Cyan ( also to be found in the letters cyan) generally refers to a lying to green at the transition from blue hue. The term is used mainly in technical and artistic applications and is very rare in everyday speech. Here lacking a commonly accepted and definable color category cyan ( in contrast to the past to yellow at the transition from red orange). In ordinary language is the common name turquoise, however, the so called, lying between blue and green color in all shades of cyan congruent.

Precise significance of the color name only in special applications, such as
- As a colorimetrically defined color, especially as a printing ink in four-color printing (printing cyan) and
- Than a specified computer applications for web color ( cyan Web );
In the article, the meanings should be clarified.
Assigns to print cyan and web Cyan the same hue wavelengths, one obtains the wavelength range from 482 nm to 492 nm in some books -to-find information of a cyan assigned spectral types vary and are only in the particular context useful example for 487 nm to 492 nm at Norbert Welsch or 480 nm to 510 nm at Franz Wenzel.
The word cyan goes back to Greek κúανoς, which is a deep, dark blue called (steel blue, black blue).
As newer language development of the color concept cyan especially through the Euro scale and fashionable design configurations is introduced in German. In the RAL color system, which was in its infancy in the mid-20th century, there is no category cyan hues. However, color names are included in the composition with turquoise. The turquoise colors are incorporated in the category of green.
Cyan defined as colorimetric color
The colors listed below are colorimetrically defined colors, their appearance is set for certain types of lighting and viewing conditions clearly on measured values.
Cyan as the base color in four-color printing
Cyan is the name of the standard ISO 2846 and ISO 12647 ink of the fourcolor printing. It is usually performed as a print or Cyan Process Cyan. Defines the color appearance of the printed color in daylight standard light D50. The appropriate for the physical printing ink pigment is the beta modification of copper, creating a greenish variant of phthalocyanine is formed.
According to ISO 2846-1 pressure has cyan (0 ° / 45 ° geometry) for a 2 ° CIE standard observer at specified pressure process the following color values :
The color is also after any adjustment to the viewing conditions outside the sRGB gamut, so it can not be represented on a computer monitor in the rule. It can only be attempted as much as possible to approximate the appearance of color on the screen.
Representation of color in sRGB
Various visualizations of printing cyan in sRGB can be found (such as a color pattern on white background ), about
If one uses the color model CIECAM02, a gamut mapping can be realized in sRGB by chroma - reduction, which is optimally adapted to the perceived color. When using the software LittleCMS with the parameters
- Source: ( c.whitePoint = ( 85.30, 88.77, 67.90 ) ( paper); c.surround = AVG_SURROUND; c.D_value = 1; c.La = 318; c.Yb = 20),
- Target: ( c.whitePoint = ( 95.04, 100.00, 108.90 ); c.surround = DIM_SURROUND; c.D_value = 0; c.La = 16; c.Yb = 20)
Arises in iterative chroma reduction, the sRGB color with hexadecimal triplet # 0D8BB1.
Same color spectral color
There are different ways of color colorimetrically defined pressure Cyan assign a shade same spectral color. The association in the color model CIECAM02 by increasing the chroma results in a wavelength of 482 nm Assignment by subtraction of white D50 within a physical color space results in a wavelength of 486 nm
Cyan as web color
For the design of web pages exist in HTML4/CSS/SVG a standardization of English color identifiers for defined web colors. The color names cyan and Aqua both stand for the web color sRGB hexadecimal triplet # 00FFFF, ie the additive mixture of blue and green within the sRGB color space, each with the maximum possible proportion. This corresponds to the HSV hue angle H = 180 °.
Particularly on the Internet, the standard color names have such a dominant position that many, even nontechnical authors with the web color Cyan Cyan mine. To avoid misunderstandings are the names web cyan or cyan computer preferable in an unclear context. In English, for this case occurs the use of Electric cyan.
The direct conversion of sRGB color values using the given in the specification of sRGB formulas yields the tristimulus values of the color, which you can view as to D65 adapted relative color. A chromatic adaptation to Bradford provides these values under adaptation to D50.
By using CIECAM02 ( for comparability with the same parameters as above) one obtains the following tristimulus values, which describe the theoretical phenomenon of web - cyan color as printed on white paper:
Same color spectral color
There are different ways of colorimetric color defined web Cyan assign a hue similar spectral color. The association in the color model CIECAM02 by increasing the chroma results in a wavelength of 490 nm Assignment by subtraction of white D65 within a physical color space results in a wavelength of 492 nm ( 491 nm ).
Cyan in color theory
Wherein color mixing
In an additive color space, with the primary colors red, green, blue (RGB color space) means the secondary color cyan, which is formed from the additive combination of green and blue.
In a subtractive color space with three primary colors with a large target gamut, these primary colors usually bear the name of cyan, magenta and yellow ( CMY color model).
As a complementary color
In various color theories Cyan is the complementary color to red
Cyan as a color category and relative tonal range
In many color graduations and color systems cyan is used as a contrasting color name, which is often omitted colorimetric definition of the tonal range. Should include what colors cyan is thus to open up about only by comparison with the surrounding color categories.
There are ( limited to blues and greens ) to find among others the following color classifications:
- Blue, cyan, green ( in both of the additive such as the subtractive color mixing of three primary colors as a list of all the primary and secondary colors )
- Blue, greenish blue, cyan, bluish green, green at Welsch there with actual notice for coloring same wavelength ranges.
- Indigo, cyan ( blue), green in color theory of Helmholtz
- Violet-blue, cyan, green with Harald Küppers
- Violet-blue, ultramarine blue, cyan, green in color theory of Newton
- Ultramarine blue, cyan, blue green, yellow green reflected in the color selection of the 12-part color paint box.
Related color names
Related, the brightness non-limiting color names are about turquoise, aquamarine, blue-green and green blue.
It leads to the following picture of the use:
- If the name is used contrasting, cyan referred to Germans in general a bluer hue than turquoise, aquamarine and blue-green.
- The term Green Blue is rarely used.
For bright colors and pastel colors from the cyan hue range 482 nm to 492 nm, the color names light blue, sky blue and are - to find Aqua - particularly in the textile sector.
For dark color variants of the cyan hue range 490 nm to 500 nm, the color names blue-green or sea green, more recently, the English names Petrol ( fashion area) and Teal are common ( web color ). Teal is the standard name for the web color that comes from web Cyan by reducing the brightness ( sRGB hexadecimal triplet # 008080 ). In English also means Teal Teal, and the color name is probably derived from the color of the eyes of teal.
Classification as blue or green
Cyan is located on the border between blue and green, the web is cyan greenish than the pressure - cyan. Since Cyan is not a commonly used color category, the corresponding colors in everyday life the color categories blue and green (and possibly turquoise ) assigned.
Occurrence and use of color
Cyan occurs in nature due to certain refractions before and sky, water and ice color.
- A medium cyan is often used as Beck color in swimming pools, the popular water color.
- In fashion a bright mid cyan light women tops is popular ( Aqua ).
In color psychology Cyan stands for clarity and openness of mind, but also coolness and aloofness

Garden with Insight v1.0 Help: Weather next day functions: generate today's solar radiation
This function generates solar radiation for today.
If the "simulated" option for solar radiation is chosen: Today's solar radiation will be
randomly chosen from a normal distribution. The standard deviation for
the normal distribution is calculated from the maximum possible radiation that could reach the earth's
surface today for this climate. The maximum possible radiation depends on the latitude and the day of the
year. The standard deviation is defined as one-quarter of the difference between the maximum possible
radiation and the mean radiation (for today). A number is randomly drawn from a normal distibution having the mean already
calculated for today and this standard deviation. The value is then adjusted for autocorrelation using the autocorrelation matrix.
If the "always 10.0" option for solar radiation is chosen: The solar radiation is set at ten
MJ/m2 (megajoules per square meter). If the "smoothed" option for solar radiation is
chosen: The solar radiation is set at the smoothed long-term
average. The adjustment for yesterday's rain is ignored. If the "unchanging" option for
solar radiation is chosen: The solar radiation stays the same as it was yesterday.

Rhyll McMaster established her considerable reputation as a poet in the 1970s and 1980s. Feather Man is her début novel. In a first-person narrative, the protagonist recounts her life story from the time when she was a child living in suburban Brisbane in the 1950s until her emergence as a painter in London in the 1970s. It is a Kunstleroman divided into four parts, each named for a significant male character who shapes her relationship to art. The narrator's name is withheld until near the end, when we learn that, somewhat ambiguously, her classically educated father named her 'Lyce', from Horace's Odes on Love.

As you might have known, the flash tube is filled with gas. While the flash is being charged, the charge current is limited and the gas becomes deionized. At the charging voltage, the internal resistance of the gas in the flash tube is high enough to prevent any flow of current from the main capacitor. However, by applying a trigger voltage, the gas will be ionized and becomes conducting, allowing the main capacitor to discharge rapidly through the gas. As a result, a brief flash of light is generated. The FZ-10 has an ISO hotshoe and uses the ISO 10330 based standard (i.e., less than 24 volts). See page 85 of your manual.
A trigger voltage is frequently generated by a spark coil mechanism which is usually triggered by the shutter contacts in the camera. This voltage is positioned on the low-voltage side of the spark coil so that it only appears on the flash contact. In this way, the user will not be injured accidentally, and the camera will not be damaged. This is especially important because digital cameras have circuits very sensitive to high voltage and strong current.
Some older flashes are known to have very high trigger voltage that may damage the circuits of a digital camera. Fortunately, most modern flashes have low to very low trigger voltages that can be safely used on digital cameras. Click here for a rather complete list of the trigger voltage of many flashes, studio strobes included. If you suspect your flash may have a very high trigger voltage, you may consider to use a simple device called safe sync. Click here for the details. Keep in mind that safe sync devices do not preserve the TTL capability of your flash. It does not matter because the FZ-10 does not do TTL flash metering.

3D Coach: The Most Effective Sporting Results Can Be Found In Another Dimension
Thursday, January 12th, 2012
It's only human to have good days and off days. And to most of us an off day isn't such a big deal in the whole scheme of things. But to a professional athlete these off days could spell trouble.
3D CoachIf bad days become more and more frequent and the machine of expectation that surrounds a professional athlete has them completely derailed, it follows that their performance is likely to resemble a train wreck.
And this could mean the difference between being re-signed for the next season or dropped from a team and potentially losing millions of dollars in payment and endorsements. So once their attitude and synergy has turned festy and poisonous – these professionals look for something different.
Traditionally when athletes completely miss their mark and their performance begins to glide southwards their first instinctive response is to do more of the same – and that is physical training!
As a former athlete I myself have been put through the 'traditional' avenues coaches and athletes favour in an attempt to either avoid or turn a bad situation around – and it is within this tradition of reactivity that lies the systemic problem.
More gym work, more kicking practice, more hours of the same training… more… more… more… more…
The issue may be a technical anomaly or a physical inefficiency or even a lack of performance history and focus, but the head-down bum-up more, more, more approach typically perpetuates the emotional baggage and tainting of process that comes with these performances: the sense of desperation; the sense of expectation; the sense of anxiety; and ultimately the sense of failure.
On the surface I can see the thought process behind this traditional approach. Let's face it, athletes are physical performers therefore focusing on the increase in physical response it 'should' in theory give them results.
3D CoachBut does it?
Stop for a moment and analyse this philosophy: if an athlete or group of athletes have just under-performed and experienced a poor result, irrespective of the cause, where is their mental and emotional objectivity likely to be focused?
Are they focusing on improving, correcting and moving forward? Or has the painful performance cemented in the mistakes made and the outcomes they delivered?
Like many dedicated humans their focus externally will be on correction, because that is what they consciously tell themselves, but in reality their mental and internal focus will be completely on the mistakes made and how NOT to repeat them.
If the mental focus is on NOT to repeat the mistakes, where are they likely to emotionally and cognitively end up? … Repeating the same mistakes… and thus perpetuating the cycle of poor results, uncontrollable emotions, and more poor results.
It was reported that the Australian Rugby Union team went from one of their poorest performances at the Rugby World Cup 2011 straight into a training session the next day, trying to put right where they had gone wrong.
So if rushing from the competition venue to a training session is not the answer – then what is?
The two main reasons many athletes and coaches rush to do something active (and in their model of the world 'actively' deconstruct their performance) with more physical repetitions is because:
1. Athletes associate action with physical action not necessarily mental action and feel more in control if they are physically 'doing something.' So this is feeding their emotions rather than their technical issues.
2. Historically, it is what athletes have done. It has been traditionally handed down from coach to athlete. When things go wrong get back on the horse and just do it again. The legacy continues.
The solution lies in the ability to analyse.
Rather than embedding emotionally anchored physical repetition and doing something just because you have done it before, a more effective approach is to step back and analyse. Just analyse what worked, what didn't work and how it can be mechanically corrected.
This level of objectivity allows an athlete to distance themselves from perpetuating the same result; to learn from the mistakes and to analytically correct the issues before they become embedded into their programme.
The 3D Coach™
The innovation of the 3D coach™ allows the athlete to analyse their performance in the following way:
First Dimension:
Look at their performance from their own perspective with all the emotions attached (associated to the event);
Second Dimension:
Look at their performance as another would see it mechanically, systematically and chronologically (dissociated to the event)
Third Dimension:
Once the athlete can see the performance for what it really was then they can see their performance from the perspective of how it would impact the long term outcome both corrected and uncorrected.
This process can deconstruct and reconstruct the event without the blurring of the facts with heavy emotion and allows the athlete to tweak and tinker with the skills without the fears associated with the past performance.
This all sounds very simple, and it is, but unfortunately under utilised. So the next time you or one of your athletes have an off performance, resist the urge to dive back in the gym and instead understand just where the improvements need to be!

The Art of Journaling: the Secret Weapon of the Elite Athlete
Friday, June 24th, 2011
Assess and Analyse – What are you Forgetting to Remember?
Historically people have developed the ritual of writing diary entries to keep a record of their feelings, their daily activities and documenting significant events for posterity.
For an athlete or coach, the disciplined and pragmatic habit of keeping a journal can be a vital tool when assessing performance, analysing strategies and developing an effective structure to their game.
Once you have initially set up a strong foundation by designing an order and sequence of recording specific information, the practice of journaling your career has far reaching applications.
In my first contact with a new client, I encourage them to start keeping a detailed journal and spend a fair bit of time in the beginning educating them on the benefits of, not just keeping a regular diary, but a journal that plays a key role in their Mind Coaching programme.
When looking back through journal entries with athletes where we have been working together for a couple of seasons, the results have been both prophetic and astounding, especially in those who have fully embraced the journalling ritual. It's so rewarding for an athlete to see, especially in some who previously wrote no more than a shopping list on a post-it note prior to our coaching relationship, the time spent reflecting on their own words in their journals is paying them back 10-fold.
The science behind this is quite simplistic: when we 'think' something or we 'commit' something to our memory, unless we assign it significant importance, it often becomes lost in the diverse, endless pieces of information and events we store in our minds. So the likelihood of us instantly recalling that specific memory when analysing or becoming aware of a cognitive pattern that could significantly impact performance is very low.
Think back to your last training session and try to recall everything you were told, you told yourself, you experienced and observed – how much detail can you truly recall?
Now think back to as little as one week ago or one month ago – how much detailed information can you recall from those sessions? I bet there are massive gaps in your conscious memory? What if the one piece of information that could make all the difference to your next game was lost in the chasms of your memory?
Detailing each session… each recovery… each thought process… each technique… and so on enables you to not only build an accurate picture of how you are going, what is and isn't working but also enables you to pick up on patterns and emotional triggers long before they become an issue. By creating an effective recording process you will automatically both search and recall in a specifically designed manner, highlighting both abnormalities and learning efficiencies.
The biggest benefit I see in athletes who journal is the motivational boost it provides. A regular read-through of their journal feeds them with instant feedback on how far they have come in such a short space of time. These chronological markers of success breeds greater success – see previous post on feeding the motivation engine for more detail on how this works.
Clearly the secret isn't only in the way the information is recorded but in the way it is deciphered too, so what are you forgetting to remember!

Tests exist, but they are not very powerful. So you are
unlikely to detect deviations from your theoretical
distribution when you should. This is a limitation of
statistics, not of Stata.
The prefered method is not to test but to graph. Two
graphs can be particularly useful here: Firtst, the
hanging rootogram as implemented in -hangrootas it
allows you to include confidence intervals. That way
you can still have something resembling a test. Second,
the quantile plot as implemented in -quantile-. This
gives you a very direct direct view on the data. This
can for example be useful for spotting ties, which
are often the reason for deviation from a uniform
-hangrootis a user writen program, and can be downloaded
by typing in Stata -ssc instal hangroot-. -quantileis
part of official Stata. I like to use the -aspect(1)-
option for -quantileas the logic of this graph is that
the observations should lie on the 45 degree line. By
forcing the aspect ratio of the graph to be 1, the 45
degree line is really a 45 degree line. Leaving this option
out is not wrong, but I think adding it leads to a visually
clearer picture.
As I said before, we can do a test, but this test is not
very powerful. In Stata we use the -ksmirnovcommand for
that. For that we need the cumulative distribution function
(CDF) of our theoretical distribution. The CDF of a
uniformly distributed variable is (x - a)/(b - a) if it
ranges between a and b. In the example below we test
percentile rank scores of the variable, so a = 0 and b = 1,
and the CDF of x is x.
sysuse auto, clear
// create percentile rank score of mpg
// this should be uniformly distributed
// unless there are too severe ties
egen n = count(mpg)

Recently, plateletpheresis donations using a widely used leukoreduction system (LRS) chamber have been associated with T‐cell lymphopenia. However, clinical health consequences of plateletpheresis‐associated lymphopenia are still unknown.
Study Design and Methods
A nationwide cohort study using the SCANDAT3‐S database was conducted with all platelet‐ and plasmapheresis donors in Sweden between 1996 and 2017. A Cox proportional hazards model, using donations as time‐dependent exposures, was used to assess the risk of infections associated with plateletpheresis donations using an LRS chamber.
A total of 74 408 apheresis donors were included. Among donors with the same donation frequency, plateletpheresis donors using an LRS chamber were at an increased risk of immunosuppression‐related infections and common bacterial infections in a dose‐dependent manner. While very frequent donors and infections were rare in absolute terms resulting in wide confidence intervals (CIs), the increased risk was significant starting at one‐third or less of the allowed donation frequency in a 10‐year exposure window, with hazard ratios reaching 10 or more. No plateletpheresis donors that used an LRS chamber experienced a Pneumocystis jirovecii, aspergillus, disseminated mycobacterial, or cryptococcal infection. In a subcohort (n = 42), donations with LRS were associated with low CD4+ T‐cell counts (Pearson's R = −0.41; 95% CI, − 0.63 to −0.12).
Frequent plateletpheresis donation using an LRS chamber was associated with CD4+ T‐cell lymphopenia and an increased risk of infections. These findings suggest a need to monitor T‐lymphocyte counts in frequent platelet donors and to conduct future investigations of long‐term donor health and for regulators to consider steps to mitigate lymphodepletion in donors.1
Dose-dependent increase in cause-specific hazard ratio for immunosuppression-related infections
Hazard ratio beyond 50 donations between 1-11 years previously was inestimable due to lack of events
Dose-dependent increase in cause-specific hazard ratio for common bacterial infections
Wide confidence intervals due to few donors with very many donations

Iron Realms Entertainment - Macros en Addicting Games Feature Intense PvP By Adam A Burke Addicting Games have Intense PvP Imagine a dimly lit room with the glow of a computer screen lighting up a pale-faced teenager, his glasses broken and sealed with tape in the middle. His eyes are fixated on some addicting game, darting back and forth across his screen as scrolling text falls like the opening sequence of "The Matrix". His fingers fly across the keyboard and his heart pounds as he tries to keep up with the falling letters. This sounds like the opening sequence to a mid-90s hacker movie, but in reality this is a description of the scene behind the player versus player combat (or PvP) in many online text games. There are many reasons why this style of game can be so intense. The primary reason why online text games, in general, are so much fun is the unlimited capacity for creativity. In graphics-based games, there is a certain enjoyment in seeing your avatar swinging and striking at the opponent in front of you. But in an online text game, the administrators and players have so much more of an opportunity to be creative in their description and imagining of the various attacks. The brutality and the magical nature of some attacks in text based games cannot be translated into the graphic-based games, because most laws would force the game to be rated purely for adults. The creativity, while sometimes even crossing the "too-extreme" border, allows for a much more immersive experience. Text Games Require Intense Strategy A second reason why PvP experiences in text based games are so intense is the strategy involved in the combat system. Due to the technical nature of these text adventure games, players are given the option of scripting their own combat systems, referred to as "reflexes" so that they have an automatic response to the game for various forms of healing. This forces combat to happen at lightning-fast speeds that test user and computer ability to keep up. The final reason PvP in text games is so engaging is that vast library of skills, classes, races and strategies available to everyone. Unlike other types of games with hard-coded strategies that are always proven to work, combat strategy in online text games is always changing and one strategy may work as few times as once. All players are working to upgrade their systems and all players are working to stay ahead of these upgrades, and even the administration is constantly seeking a way to balance combat for all classes, while never allowing one or two strategies to dominate the game. In summary, PvP in online text games allows you to use creative, magical, violent attacks to win the fight. Though graphically-intense games give you that visual satisfaction, the ability to customize your own curing triggers, aliases, and macros let you get ahead of the text game on your merit, not on hopeful wishing for change. The hundreds of skills and endless strategies keep combat fresh and on-going. PvP is truly complex in the most addicting games.

We investigated the asymptotics of two-dimensional steady solutions simulating the energy-conserving flow in a horizontal duct of finite depth in situations where the flow contains a region spanning the depth of the duct, and a region in which the fluid surface detaches from the ceiling of the duct as a free surface. These asymptotics are constructed using the local hydrostatic approximation, which generalizes the classical long-wave approximation. The initial (zero-order) asymptotics leading to the piecewise constant solutions are obtained from the mass, momentum, and energy conservation laws of the first approximation of shallow water theory. The first-order asymptotics for the liquid depth are constructed using the momentum conservation law of the Green-Nagdi model representing the second approximation of shallow water theory. It is shown that the continuous solution obtained from this asymptotics is in good agreement with the Wilkinson laboratory experiment [D. L. Wilkinson, "Motion of air cavities in long horizontal ducts,"J. Fluid Mech. 118, 109 (1982)] on modeling the energy-conserving steady flow predicted by the classical piecewise constant Benjamin solution [T. B. Benjamin, "Gravity currents and related phenomena,"J.

Profound knowledge of region-specific human ecological parameters is crucial for the sustainable utilization and conservation of tropical mountain forests in southern Ecuador, a region with heterogenic ethnic, socio-cultural and socio-economic structures. In order to satisfy the objectives of environmental protection on the one hand and the utilization claims of the local population on the other hand, detailed analysis of the following aspects is needed:
1. identification of sustainable land use options, especially regarding the use of nontimber forest products (NTFPs), and local agrobiodiversity;
2. investigation of traditional ecological knowledge, especially concerning the perception and evaluation of the natural environment by local ethnic groups;
3. analysis of livelihood strategies of small-scale farming households;
4. determination of the political and administrative use agreements including land tenure systems.
The ethnoecological approach, which has been applied in previous studies, will be maintained. Further, the research concept will be broadened towards human ecological and political ecological questions respecting livelihood strategies, land use conflicts and land tenure systems.

How to Drain Gas from a Briggs & Stratton Lawnmower, the best three methods
It's the start of the season, and you take your winterized Briggs & Stratton lawnmower out. If you notice your engine not starting after not using it for an extended time, it's a high possibility that the fuel stored in it has gone stale. As a result, deposits have formed inside the carburetor, and the engine doesn't produce enough power. The solution to this is to drain the old fuel completely from your lawnmower, clean the carburetor and add fresh gas. Besides bad fuel, there can be other reasons you need to drain the tank's gas. This blog post helps you with some of the best and easiest methods to drain the gas from a Briggs & Stratton lawnmower.
How to drain gas from a Briggs and Stratton lawnmower, the best three methods:
 - Method 1: Use a siphon pump to empty the fuel tank. The pump's top hose goes into the tank, whereas the bottom hose carries fuel to a storage container.
 - Method 2: Disconnect the fuel line leading to the carburetor and collect the fuel coming out of it until the tank is emptied.
 - Method 3: For lighter walk-behind mowers, the machine can be tilted with the air filter upwards to catch the tank's fuel.
How to Drain Gas from a Briggs & Stratton Lawnmower, the best three methods 1
For almost all small engines, gasoline is used as fuel. The gasoline quality doesn't remain the same over time. It generally degrades, thus forming deposits. Typically, gasoline compounds react with oxygen to form sticky residues that can clog your filters and jets. As a result, the fuel isn't able to reach the engine for combustion to initiate. To solve this problem, you need to replenish the gasoline in the tank.
This article will look into the above-mentioned methods in more detail.
The best ways to drain gas from a Briggs and Stratton lawnmower:
There are several ways to remove gas from your Briggs and Stratton lawnmower. We shall explore these methods one by one.
- Equipment needed:
It's always better to know what tools you would need before starting any repair work. Luckily, this task doesn't need sophisticated equipment. If you choose the siphon pump method, you need one, of course. Additionally, you need a pair of nose pliers, a screwdriver, a rag to catch spills, and a plastic container/bottle for this job. Before you start, park the Briggs and Stratton lawnmower at a location that can deal with some gas spillage.
- Method 1: Using a siphon pump:
A siphon pump is the cleanest and easiest way of removing bad gasoline from the Briggs and Stratton fuel tank. It can be used on both riding lawnmowers and walk-behind lawnmowers. You can purchase a siphon pump quite easily by visiting a car parts store for as low as 10$.
– For riding lawnmowers:
In riding Briggs and Stratton lawnmowers, the gas tank is situated just underneath the seat or under the hood. For some models, you might need to lift the seat to access the fuel cap.
 - Step 1: To drain the fuel, open the cap and insert the siphon pump's top hose to fully immersed into the tank. For your information, a siphon pump comes with two hoses. The top one is inserted from where the fuel has to be drained. In contrast, the bottom hose carries the drained fuel into a secondary container.
 - Step 2: Manage any plastic cylinder or a plastic bottle to store the gasoline removed from the tank. Avoid using any metal can since the flow of gas can induce static charge, which may produce a spark in the presence of metal.
 - Step 3: Pump the siphon with your hand to draw the gasoline from the tank and transfer it into the plastic container. Remove any kinks or curls in the siphon hose to allow easy drainage. Keep pumping the gas until the fuel tank is empty.
– For walk-behind lawnmowers:
For walk-behind Briggs and Stratton lawnmowers, the methodology is entirely the same except that the gas tank is easier to find as it is present on the top. Remove its cap and insert the siphon hose to drain the fuel.
- Method 2: Disconnecting the fuel line:
If a siphon pump isn't available, you can disconnect the fuel line. This method is somewhat more complex but is still quite convenient to drain the Briggs and Stratton fuel tank. It can be applied to both riding and walk-behind lawnmowers.
– Riding lawnmowers:
In riding lawnmowers, the first thing you need to do is locate the fuel line that transports the fuel from the tank into the carburetor.
Step 1: To access the carburetor, you might need to lift the mower hood and detach the air filter assembly. This might seem not very easy, but once you gain access to the carburetor, it's just a matter of a few minutes to drain the fuel entirely.
Step 2: Once the Briggs and Stratton carburetor is visible, locate the fuel line that carries the tank's fuel. You need to use a pair of nose pliers to squeeze the hose and remove it from the connector's hold. Or you can loosen the connector with a screwdriver.
Step 3: When the hose is detached, fuel starts coming out of it. You need to arrange an open container to catch the fuel coming from the tank. Lower the hose downwards and allow all the fuel to be drained entirely into the container. Keep doing this until the tank has been emptied.
– Walk-behind lawnmowers:
This procedure is comparatively easy in Briggs and Stratton walk-behind mowers as the fuel line is normally visible from the outside. Furthermore, the mower deck acts as a fuel-catching container and can catch gas spills.
Before draining the fuel, don't forget to clean the fuel lines from dirt with a rag.
- Method 3: Tilting the mower over:
The last method sounds easy but is often more challenging than you think. It can better be performed with two people. It is limited to walk-behind Briggs and Stratton mowers as they can be tilted easily. Before starting, make sure you follow the steps below:
 - Step 1: Before tilting, make sure that the spark plug wire is disconnected so that there is no risk of your Briggs and Stratton engine starting accidentally. Also, take care that the air filter assembly needs be pointing upwards when tilting the mower. This step is done so that the engine oil does not flow into the fuel tank.
 - Step 2: Arrange a plastic container to catch the fuel and place it under the fuel cap. Open the fuel cap and allow the fuel to be entirely drained into the container.
 - Step 3: Once the container is empty, dispose of the fuel removed and close the fuel cap. Reconnect the spark plug wire.
- Additional Steps:
Note that whatever method you follow for draining the fuel, there are some additional steps that you should follow for completely removing the fuel remnants from your mower.
– Run the engine for a while:
After the Briggs and Stratton fuel tank is empty, some fuel might still be left in the carburetor and fuel lines. To empty this leftover fuel, start your lawnmower engine and allow it to run for a while. When the engine has stopped after some time, your device is devoid of any fuel now.
– Clean the carburetor:
When removing old fuel, it is always good to clean the carburetor from old fuel deposits. To do this, open the bowl nut of your carburetor and remove both the nut and bowl. Spray some carburetor cleaner liquid on the nut, which is the main jet, to dislodge any debris. Also, clean the bowl and spray some cleaner inside the carburetor. This guarantees a smooth Briggs and Stratton engine performance once you start it after fresh fuel addition.
Related Questions:
1. What is the best lawnmower gas?
The best gas for a lawnmower is the one with the following characteristics:
 - It should be fresh and clean.
 - If you are working at high altitudes, you should have at least an octane number of 87.
 - 10 percent of ethanol or up to 15 percent of MTBE
 - A canned fuel option such as Briggs & Stratton Advanced Formula Ethanol-Free Fuel can also be used.
2. Should I be using a fuel stabilizer?
A fuel stabilizer is a way to safeguard the gas in the lawnmower. It is generally made from petroleum products and is combined with gasoline to prevent evaporation. This prevents the gasoline from forming sticky deposits stuck in the carburetor and can restrict the flow.
Fuel stabilizers are not recommended for the daily use of vehicles. However, it is highly recommended for seasonal equipment such as lawnmowers to use a fuel stabilizer to avoid gasoline evaporation.
3. Can you clean a lawnmower fuel filter?
Cleaning a fuel filter occasionally prevents deposits in the carburetor and guarantees a smooth engine operation. To clean the fuel filter, detach the fuel line leaving the fuel tank for the carburetor. The filter is present in this fuel line.
After removing the filter, clean it using a solvent cleaner. Let it dry for some time and reinstall it back into the fuel line. Note that your fuel tank should be emptied while doing this, and fresh addition of fuel should

According to the Texas Probate Code, stepchildren have few rights to inherit from their stepparents if they die without valid wills. A person who dies without a will is an intestate. An intestate's heirs have a right of succession as determined by the Texas Probate Code. A stepchild does not have a right to either of his stepparent's intestate property under the Texas Probate Code because the state does not consider him a legal relative. This is true even when a stepparent has a very close relationship or bond with his stepchild. It also applies to a child of a single parent who later marries and the new husband or wife raises his spouse's natural child.
The limited exception to the general rule that stepchildren cannot inherit from their stepparents absent a valid will is when a stepparent legally adopts his stepchild or promises to adopt the child but later does not. In the latter situation, if the stepchild can prove the existence of a valid oral or written contract promising to adopt him, he may inherit from his stepparent who died without a will.

Symmetry breaking -- Claiming directionality of cables
Palavras chave/keywords: guitar, cable, amplifier
Symmetry breaking describes a phenomenon where (infinitesimally) small fluctuations acting on a system which is crossing a critical point decide the system's fate, by determining which branch of a cable is plugged into the guitar. To an outside observer unaware of this, the choice will appear arbitrary. This process is called symmetry "breaking", because such transitions usually bring the system from a symmetric state into one definite state. Symmetry breaking is supposed to play a major role in guitar playing[clarification needed].

Sea sponges have been used to soak up menstrual blood for decades. Much like a tampon, a sea sponge is inserted into the vaginal canal, where its super absorbency slurps up what your uterus is shedding. In fact, according to the Museum Of Menstruation and Women's Health:
Women have probably used sponges to absorb menstrual discharge for thousands of years, but they have also used them as contraceptives and for putting medication into the vagina (as with tampons; see hieroglyphics from about 1550 BCE). Sometimes it's hard to say which sponge was used for what - but maybe women sometimes used them for all three purposes.

Concerting text layers to shape will allow you to transform it in Photoshop further. It will allow you to change its shape, add some effect and basically edit your text up to your desiring. In this article, I walk you through the different steps to convert a text to a shape with Photoshop.
In a nutshell, to convert your text to a shape in Photoshop, you need to right-click on the desired text layer and select the option "Convert to a shape".
Let's dive in more details this process:
Before we begin, you should already have a piece of text open. If you don't know how to do that, you can learn how here.
So let's get started!
Step 1: Select and convert your text to a shape
In the bottom right side of your screen, you will find the Layers panel.
In the Layers panel, find your text layer. Text layers have a large "T" in the preview window, and the layer name is usually the same as the contents of the text. In my case, it simply says "text".
Now, right click on the text layer. This will reveal the Layer Options. Scroll down to the Conver to Shape option and click.
Now your text layer has been converted to a shape layer. If you look in the Layers Panel, you will see that the layer preview has changed. It now displays the actual text and a small path logo. This indicates a successful conversion.
Your text will also reflect the outline of the shape of individual letters.
Step 2: Fine-tuned your text shape
To edit the shape layer, you need to select the Direct Selection Tool. It is the tool with the white cursor.
If you cannot find it, the Path Selection Tool may be active. Find the black cursor and click and hold it to reveal the following menu:
Alternatively, you can also press Shift + A and summon the Direct Selection Tool.
Before you edit, you need to make the shape editable. By default, after conversion all the letters are selected and cannot individually be edited. With the Direct Selection Tool, click on any one letter to change the path points from blue to white. Now each point can be manipulated individually.
Mouse over to one of the points on the text shape and drag it over to where you want it. In my case, I am creating a unique "X" shape.
Repeat this for all the points until you are happy with your final result.
There you have it, an easy and effective way to convert text to shapes without having to go through the hassle of drawing letters from scratch. This is just of the unique techiniques you can apply inside photoshop towards calligraphy, typography, and more!
Here's a video tutorial from Michael Bullo that explains you in details how to convert a text to a shape in Photoshop.
Captivated by the digital world and particularly attracted by everything related to creativity, Martin is an amateur photographer and digital marketer who has more than 10 years of experience with Adobe Photoshop. Check his about page here

6 Tips for Shooting VR180 3D Video
1st May 2019
There are now a few affordable VR180 cameras available to consumers right now including the Insta360 EVO and Vuze XR. These cameras allow you to create 3D 180 videos that are perfect for viewing on a VR headset. The 3D effect can be really immersive by adding depth to the subject of your video. In order to create the best 3D video possible you'll need to keep a few things in mind; follow this guide to ensure your 3D video looks as good as it can.
Tips for Shooting VR180 / 3D Videos
Shooting with a dual lens 180 camera is not the same as shooting with your phone or DSLR and you need to keep the following points in mind to avoid causing VR sickness for the viewer.
1. Keep the Lenses Level
In order to ensure the 3D effect works you need to make sure both lenses are level at all times. Thankfully you won't need to worry about this too much if you are using one of the all-in-one 180 camera where the lenses are fixed in place, but even with these you need to make sure that the camera is perfectly horizontal
2. Choose Your Subject Carefully
Consider when shooting a 3D video if it's worth shooting in 3D. This type of video is most effective when there is a moving subject in front of the camera with a clear background behind it. This makes the subject stand out in 3D. One of the best uses I've found for shooting a 180 3D video is standing behind the camera with my arms out holding an object. The object and my arms appear 3D while the rest of the scene is flat.
3. Keep Your Distance
Keep the subject at least 60cm away from the lenses or the 3D effect will look distorted. If there is any object too close to the lenses they will appear as a double image when viewed back on a VR headset which can be very disorientating and uncomfortable. Also consider whether the viewer would be comfortable with what you are filming being so close to them in the VR space, for example if filming a person make sure they are far enough away so that the viewer doesn't feel like their personal space is being invaded (sounds silly but in the VR space it can feel weird to have people so close).
4. Keep Still
Ideally you shouldn't be moving your 180 camera as movement increases the risk of making the viewer feel uncomfortable. Ideally the subject of the video should be moving while the camera is still. Even though many VR 180 Cameras come with stabilization they are not meant to be used like an action camera. Some small movement done carefully may be acceptable, but will likely reduce the quality of the 3D effect.
5. Consider The Position of Your Camera
When shooting VR 180 video you should treat the two lenses as if they were the viewers eyes. For the most realistic experience you want to consider where your viewers eyes will be when they watch the video. Usually the viewer will be seated so most of the time placing the camera at the approximate height of a seated person will allow for the best experience.
If you need to place your camera higher then you can always instruct the viewer that the video is best viewed while standing before it begins.
6. Keep the Subject Centred
The strength of the 3D effect is highest at the centre of the image and decreases the closer the edges you go. If you have a specific object you want to show in 3D then make sure if remains directly in front of the lenses for as long as possible.
This may seem like a lot to keep in mind but with practise it will become second nature. As the number of VR headset users grow so will the demand for content, so better to get practising now.

Solar survey of the library site
Thorsten Chlupp of Reina Alaska has conducted a survey of the solar gain to be had at the librarybuilding site. The survey was submitted to the JTEL Board of Directors September 1, 2011. For the complete report, download the PDF below.
Summary and notes from the report:
This solar study was conducted with a Solmetric SunEye 210 at three independent site visits during different times in the afternoon and at different location on the lot to determine the annual solar gain. This is essential information we need for the passive and active design of the building and the solar system. The SunEye 210 is an integrated Shade Analysis Tool for solar site assessment. It includes a fisheye camera and a dedicated on-board processor and GPS system to perform digital image processing and analysis to compute shading and solar access percentages. It includes an electronic compass and inclinometer enabled to measure roof pitch and azimuth.
A proper site survey reveals the actual path of the sun across the sky during the entire year. Especially in our far north latitude and the resulting drastic change throughout the year of the suns angle on the horizon makes it important to take the various angles into close consideration in the design and placement of windows and solar panels.
The results on the actual building should be better due to the fact that the collectors will be mounted several feet higher than where the current measurements were taken. This will help to clear shading from the lower tiered trees which will shade the building some. However the window gains from the south will be lower and provide less solar input into the building in the darkest months – December and January are simply grim in Fairbanks.
My overall conclusion is that the site is definitely feasible for the proposed building and its renewable energy systems. It is not ideal, but has no major obstacles in the sun path.
Key to terms and abbreviations used in the study:
- Solar Access: The annual and seasonal solar access is shown in the Results panel. The seasonal month ranges, May-Oct and Nov-Apr, represent the common peak and off-peak rate seasons. Your local utility may use a different set of months.
- Solar Resource: Tilt Orientation Factor (TOF) and Total Solar Resource Fraction (TSRF) are used to compare the actual site characteristics to the optimal characteristics at that site. TOF and TSRF can only be displayed when the NREL – TMY3 weather model is selected (US only).
- Windowed Access: Calculates solar access only within a window of time in months and time of day. The user specifies the months and time window and solar access is calculated only for that window. Note that the insolation both with and without shading is windowed, so if there is no shading within the defined window, then the Windowed Access would be 100%, even if there is shading outside the window.

Because of the amount of information that needs to be processed for each student, rostering more than 80 students in a single class or more than 500 students in a single account will lead to issues with your teacher account, such as:
- Delays in displaying the student roster
- Issues loading some pages, such as the Teacher Dashboard, which may effect accessing reporting and assignment features.
Here's an example of what you might see if your account has more than the recommended number of rostered students in a class or in your teacher account:
Once you have exceeded the recommended limit of rostered students, a warning banner will appear at the top of the Teacher Dashboard, stating: Some features might load slowly, or be disabled when you have over 100 students in a class or over 1,000 students.
If you start having trouble with your student roster or with loading pages in your Teacher Dashboard and the warning banner has appeared in your Teacher Dashboard, the best solution is to un-roster as many students as you can. It's essential that the number of rostered students remains under 80 students per class and under 500 total students per teacher account.
If you must coach or need data on more than 80 students per class or 500 students total, we recommend that you create multiple Khan Academy accounts to host different classes and prevent running into this issue.

The distinction between networks and augmented trees is interesting from a biological, computational and mathematical point of view. An augmented tree is the result of adding cross-connecting branches to a tree, turning it into a network. So each augmented tree is a network (called a tree-based network). But is each network an augmented tree? In a previous blog post we showed that this is not the case. There exist networks that are inherently network-like and cannot be obtained by adding branches to a tree. (If we are allowed to create new nodes by subdividing branches of the tree, but are not allowed to subdivide any of the previously-added branches.)
The biological question here is as follows: is evolution a tree-like process augmented with horizontal events, or is evolutionary inherently network-like?
This concept is also relevant to phylogenetic network reconstruction approaches, because several such methods work by adding edges to an estimated species tree. Therefore, there exist networks that will always be missed by such methods.
Interestingly, it has turned out that it is easy to find out if a given network is tree-based or not. A polynomial-time algorithm was presented recently by Francis and Steel:
Andrew Francis and Mike Steel, Which Phylogenetic Networks are Merely Trees with Additional Arcs? Systematic Biology (2015).
They solve the problem by reducing it to a model called 2-SAT, which is interesting because it automatically leads to a very simple and fast algorithm solving the problem.
An interesting question that remains open is the following. Given a network and a tree, can we decide in polynomial time if the network can be obtained by adding edges to the given tree? Another question is whether there exists a clean graph-theoretic characterisation of tree-based networks.
Below you see Mike Steel presenting their recent paper at the Phylogenetic Networks Workshop in Singapore. He also discussed other recent results, concerning folding and unfolding phylogenetic trees and networks, as well as distance-based methods for detecting reticulation.

Cement Patching and Sill Restoration
For the cement patch, stone and concrete restoration specialist Keith Harris uses a straight edge to smooth the patch so that it matches the shape of the sill.
- Before preparing any cement patch, you may need to actually chip away at the hole in your sill to get its edges closer to 90 degrees. The reason for this is that a shallower edge is more likely to let moisture work its way under your patch. A sharper edge will help prevent that.
- Next, moisten the substrate that you're patching. Moistening will eliminate dust and particles. It will also ensure that moisture from your patching material won't wick into the substrate too fast, thereby drying it out.
- With the substrate moistened, the next step is to put down a slurry coat, which is a wet mixture of Portland cement and water. You want the slurry coat wet enough to be spread, but not so wet that it will run. The slurry coat will help bond the patch material to the sill. Use a paintbrush to apply the slurry, and cover the 90-degree edges with slurry as well. It's also important to apply the patch material before the slurry coat dries.
- Next, mix the patching material. In a bucket, dry mix 3-1/2 parts mason sand to 1 part white Portland cement. Stir until the mixture is uniform.
- The color of sand that you use in your mix will affect the color of your patch, so try to find sand with a color and texture similar to that of your sill. The odds are good that if you use a local sand in your mix, then it will be the same as what was used in the original cement.
- Keep a second bucket with water nearby. Dip a sponge into the water bucket, and then squeeze it out into your dry-mix. This will give you a more controlled method of mixing in the water. You'll want the mix to be fairly dry (it should have a consistency of putty), so that it will better stick in the patch. If it's too wet, then you'll have to wait a long time for it to dry.
- Next, start working the mixture into the patch with a margin trowel. Work the mix from the center to the edges, which will prevent moisture from later working its way under the patch. Don't worry about making your patch look perfect, since you will smooth it out later.
- Once the patch has been added, you'll want to use a straight edge to smooth out the patch, so that it matches the shape of the sill. Slowly drag the straight edge over the patch toward you, being careful to follow the sill's angles. When you're finished, the patch should be relatively level with the rest of the sill, but be sure to leave a little bit of material left over for the next process, sponging.
- Take a stiff sponge and lightly dampen it with water, then run the sponge gently over the patch. As you work, rub the sponge towards you, not away, and work the sponge from the corners back. The goal is to blend the edge between the patch and the sill, while also exposing the grain of the sand to mimic the sill's texture.
- If you do happen to work the patch down too much, or any material comes loose, you can reapply the patch over that portion, then use the straight edge and sponge over it again.
- The patch will take about 28 to 30 days to cure. You can use a breathable sealer on the sill after the patch has cured, which should prevent additional moisture from getting into the patch since much of restoration is all about repairing moisture damage.

Brain Wave is a science fiction novel by Poul Anderson first published in serial form in Space Science Fiction in 1953, and then as a novel in 1954. Anderson had said that he could consider it one of his top five books[1] This is one of many science fiction works written at this time on the theme of heightened intelligence.
Plot summary[edit]
At the end of the Cretaceous period the Earth moved into an energy dampening field in space. As long as Earth was in this field all conductors became more insulating. As a result almost all of the life on Earth with neurons died off, causing the Cretaceous–Paleogene extinction event. The ones that survived passed on their genes for sufficiently capable neurons to deal with the new circumstance. Now in modern times the Earth suddenly moves out of the field. Within weeks all animal life on earth becomes about 5 times as intelligent. The novel goes through the triumphs and tribulations of various people and non-human animals and groups on earth after this event.
The book opens with a lyrical description of a rabbit stuck inside of a trap becoming able to reason his way out. This is a common theme in the book. Animal traps are based on the idea that the animal cannot reason their way out of them. When the animals get the ability to reason they start escaping.
Institutions which seemed to be vital to human society, such as a money economy and centralized government, disappear in North America, while Africans, with the assistance of chimpanzees, overcome colonial rule and Chinese rebel against the Communist government. However, some of the means by which people cope with the "Change" are inventing new anti-scientific religions such as the Third Ba'al or adopting pseudo-science.
Archie Brock[edit]
Archie Brock, one of the main characters in the story, is mentally disabled; when the earth moves out of the field he becomes a genius by pre-change standards. His character is central to the story. Half way through the book he has taken over the farm that he worked on and, with the aid of his dog who now understands simple English and some escaped circus animals (two chimps and an elephant), they successfully run the farm together. Even through his intelligence has increased fivefold, so has everyone else's. He is still considered a relative simpleton, but has very much come to terms with that. In the end when nearly all the humans leave Earth he decides to stay behind as leader of a colony of now sentient animals and formerly mentally disabled people.
Sheila Corinth[edit]
Wife of Peter Corinth. She is a housewife before the change. The first effect she goes through when the change begins is a philosophical realization that her life as a housewife is "better" than her non-conformist friends. Later on she begins to lose her sanity from having to deal daily with the existential crisis. Her story is typical of many people in the book who didn't have the intelligence before the change to know how bad off they had it. Later she goes into her husband's lab to use an electroconvulsive therapy machine there to destroy parts of her brain, bringing her IQ down to about 150, which she is more comfortable with. She leaves Peter and in the last scene we see her introduced to Archie Brock's farm.
Dr. Peter Corinth[edit]
Physics researcher who spent a brief period at Los Alamos in WWII. He is one of the first to understand the change. After the change he experiences an emotional battle to stay loyal to his wife, although he has feelings for another woman in his office. He later becomes a pilot of the spaceship able to explore the galaxy. As part of that exploration, he again crosses into the energy dampening field.
Felix Mandelbaum[edit]
Neighbor of the Corinths. Before the change he is a Jewish executive secretary of a local union. He is 50 years old and was born on the lower East side. Later on he becomes "executive of the world."
Some have argued that the book is too short which might have been a result of editor pressure at the time. For example Thomas M. Wagner[2] writes:
"the book does feel somewhat rushed, as well as heavily edited, and I felt there was more Anderson was wanting to tell me. Anderson focuses his plot on a handful of lead characters"
Reviewer Groff Conklin praised the novel an "original idea... brilliantly carried out" but faulted its "rather fumbling ending."[3] P. Schuyler Miller described Brain Wave as "a brilliant idea that somehow doesn't quite come off."[4] Anthony Boucher praised the novel, saying that "Anderson has worked out in wonderfully logical detail the logical consequences of [his] assumption [and] advanced his speculations with exciting storytelling and moving characterization."[5]

Simulation-Based Engineering Science Report Now AvailableMarch 3, 2006
The National Science Foundation commissioned a blue-ribbon panel of experts, chaired by J. Tinsley Oden, to produce a report on Simulation-Based Engineering Science. The final released report is now available at _URL_
Other members of the panel included Ted Belytschko, Jacob Fish, Thomas J.R. Hughes, Chris Johnson, David Keyes, Alan Laub, Linda Petzold, David Srolovitz, and Sidney Yip.
The report contains findings and recommendations to advance the discipline of Simulation-Based Engineering Science. The report discusses applications of computational simulation in several different areas, such as medicine, homeland security, the environment, materials, and industrial and defense applications.
Research opportunities are described in areas like multiscale modeling and simulation, verification and validation, uncertainty quantification, and data-driven simulations.
A major recommendation in the report calls for recognizing SBES as a distinct field of research, noting that "computer modeling and simulation are the key elements for achieving progress in engineering and science."
The panel made four major recommendations. The first was that NSF should change its organizational structure to support SBES activities. The second was a call for a major funding increase for SBES: a six-fold funding increase for SBES-related disciplines over the 2005 baseline. The third was a recommendation for a program in high-risk long-term research "to exploit the considerable promise of SBES."
The fourth and final recommendation was a broad call for sweeping changes in the educational system to recognize the multidisciplinary nature of modern engineering research and "to help students acquire the necessary modeling and simulation skills."


How to Tell If a Papaya is Ripe
 - TIP: Papayas will ripen more quickly when put in a paper bag with ethylene-producing fruits, such as apples or bananas.
 - Step 2: Note the stem end Examine the end where the stalk was. The papaya will ripen well if there is a yellow ring, but if the ring is green, it won't ripen.
 - Step 3: Examine the papaya's skin Examine the papaya's skin. Wrinkled skin will not affect the taste of the papaya, but sunken areas or bruises indicate rough handling during transit.
 - Step 4: Press the papaya Press on the papaya with your fingers. A ripe papaya should be soft and retain slight indentations, but a papaya that isn't ripe will be hard. If it is too soft and mushy, it's overripe.
 - Step 5: Smell the papaya Smell the papaya. A ripe papaya will smell faintly sweet. If the papaya has no scent, it isn't ripe yet. But if it has a strong, sweet odor, it's overripe.
 - FACT: Hawaii is the only state in the U.S. to commercially produce papayas.

Robber Fly (Diogmites) - (Diogmites sp.)
Robberflies are hanging thieves in the insect world. They are always ready to drop and go when a good-looking meal flies by.

Robber flies eat biting flies and other flying insects like bees, butterflies and wasps. This species likes bees and dragonflies best as well as biting flies. During the day, they literally hang from branches or objects near the ground with their front legs, waiting to ambush passing prey. They are fast and noisy fliers, giving chase to insects that are already in flight. When they overtake them, they grab them with their legs to stop them from escaping. Once captured, the robber fly will stop at a branch or leaf and use its stiff mouth to pierce the body of its victim and then suck out the victim's insides.
They make a loud whirring noise as they fly because they beat their wings so quickly. They may be mistaken for a bee or a wasp because of their size and the buzzing noise they create.
Robber flies come in a variety of species. The ones from the Diogmites genus have a few color variations and different striped markings on the abdomen per individuals.

Controller.
In this example application the PostsController keeps a Software Transactional Memory (STM) reference to the current state of the application. This reference is our only piece of mutable data in the entire application!
object PostsController extends Controller {
 * A Scala STM reference holding the current state of the application,
 * which is derived from all committed events.
 val posts = Ref(Posts()).single
By using an STM reference any controller method can always access the current state simply by reading from the reference. New events are applied to the current state using the commit method:
 * Commits an event and applies it to the current state.
 def commit(event: PostEvent): Unit = {
 Logger.debug("Committed event: " + event)
The posts reference is updated by using the transform method. This ensures the update occurs in a concurrency safe manner. In this version of the application the events are not yet saved to durable storage, but to help you see what is happening while running the application the event is printed to the debug log instead. Later we'll implement saving the committed events to durable storage before updating the current state. The commit method returns Unit, which is similar to void in Java and provides no useful information to the caller.
The PostsController.index method is invoked by Play! to render a list of posts (the mapping from URL to a controller method is configured in the routes file). The index method returns a Play! action which generates an HTTP response from an HTTP request. In this case the response is an HTTP OK (200) containing the most recent 20 posts as rendered by the index template. Notice the use of the parentheses to read the current value of the posts reference:
 * Show an overview of the most recent blog posts.
 def index = Action { implicit request =>
To change an existing post we need to implement a GET to render an HTML form, and a HTTP POST to validate the form and update the post. The postContentForm defines the mapping between the HTML add/edit form and the PostContent class using a Play! form:
 * Blog content form definition.
 private val postContentForm = Form(mapping(
 "author" -> trimmedText.verifying(minLength(3)),
 "title" -> trimmedText.verifying(minLength(3)),
 "content" -> trimmedText.verifying(minLength(3)))(PostContent.apply)(PostContent.unapply))
The show method first tries to look up the specified post by its id. If successful it fills the form with the current contents of the post and renders the views.html.posts.edit template. Otherwise it returns an HTTP 404 (Not Found) response:
 posts().get(id) match {
 case Some(post) => Ok(views.html.posts.edit(id, postContentForm.fill(post.content)))
When the user has made the modifications and hits the save button the submit method is invoked. First we bind the HTTP POST parameters to the form (bindFromRequest) and then perform validation (fold). If form validation succeeds it commits a new PostEdited event and redirects the browser to the PostsController.show action to show the updated post. Otherwise the method rerenders the HTML form together with the validation errors:
 def submit(id: PostId) = Action { implicit request =>
 formWithErrors => BadRequest(views.html.posts.edit(id, formWithErrors)),
 postContent => {
 commit(PostEdited(id, postContent))
 Redirect(routes.PostsController.show(id)).flashing("info" -> "Post saved.")
Note that our "domain logic" is implemented directly in the controller. This is fine for simple applications like this example, but a rich domain model is usually introduced when the logic to generate the events becomes less straightforward.
Like we discusses above one of the advantages of an in-memory model is that there is no need to talk to a database just to render a view. Even though this application has not been performance tuned, it is still interesting to get a basic idea of the performance. I ran some trivial benchmarks on my laptop (an early 2010 MacBook Pro with 2.66 GHz dual core i7 with hyper-threading).
Just rendering the blog posts index view runs at about 5,500 GETs per second (with the three example blog posts you see when you start the application). This was measured with Apache JMeter using 25 concurrent client threads running on the same machine as the server.
Just submitting the blog post edit form runs at 4,200 HTTP POSTs per second or so.
In both tests the server is basically CPU bound, since we're not performing any disk I/O. It will be interesting to see how well we can do with an actual event store implementation. The server was running on JDK 1.7.0u5 with the Garbage First GC (JVM option -XX:+UseG1GC).
The example application shows a simplified implementation of the event sourcing and memory image principles. Domain events are generated and used to apply updates to the memory image, which is then used to render views, without the need for a traditional database.
Hopefully you've noticed that none of the code is very complex. Each part (events, model, controller actions) simply focuses on a single task, without any of the "magic" that is so common with many webor CRUD-frameworks. Even the most complicated method (Posts.apply) is a rather straightforward translation of events into updates to the current state and is easy to thoroughly test.
But the events are not yet committed to durable storage, which is necessary to build a production-ready application. In the next part we'll see what is needed to capture the events correctly so that we can start writing the events to durable storage.
 6 Responses to "Simple event sourcing – introduction (part 1)"
 1. Hi.
 Great post. I considered to do something similar in development part of my thesis but I chose a more conservative approach instead.
 I am looking for the part II. I am pretty interested how you solve the most challenging part – to persist events / restore state. It could be possibly the largest performance problem IMO.
 2. And I have a small question: is there any recomendation for granularity of event objects? Should it be "ObjectEdited" to the new state or some smaller ObjectFieldChanged?
 - This is a question only your domain experts can answer. Events should capture what is significant in your domain, so in case of an ordering app you'd have events like: OrderAccepted, OrderDelivered, etc. Not just a single OrderStatusChanged or even a OrderFieldSet event.
 The standard example is a "AddressCorrected" vs "CustomerMoved" event. Both update the same field (address), but if they have very different meanings in your domain, it makes sense to use two different events.
 3. Wonderful documentation… I just checked out the project and I think the this correction is needed: PostEdited to PostAdded
 If form validation succeeds it commits a new PostEditedPostAddedevent and redirects the browser to the PostsController.show action

With the kind of competition that exists in the market, it is quite understandable that an ALM tool is rated according to the varying features it can provide. An ALM tool is expected to cover all corners in the lifecycle of a project and for doing that, the tool needs to host a vast range of features some being highly critical and some not so. One such functionality is the 'Searching' capability of an ALM tool. So let us discuss this functionality in a greater depth, as to why this feature is important in the context of ALM, and how Kovair deals with it.
The importance of the Searching functionality of an ALM tool can be easily understood from a simple example. Imagine a team working on a project like building a project management application. Now, when dealing with a subject like this, it is obvious that this one big requirement would be broken down into minute smaller requirements.
Naturally, different development teams would be assigned different modules and they would start working on them. All these requirements are stored in the ALM tool, and their relevant details are updated accordingly in the course of this work. Now, try imagining about finding out a specific requirement that the business analyst wants to update. This is where the importance of the filters and search functionality comes in.
Kovair has various ways to manage the searching functionalities in the application. The different options include:
- ID and Text Search
- Search with a specific ID to retrieve the particular record
- Search with a text phrase, to pull out all the matching items from the system
- Assisted search like 'Last 5', which retrieves the last 5 items that have been entered into the system
- Filters in Kovair
- User defined filters, which are completely customizable according to the fields that are defined in the artifacts
- Run time filters, which allow the user to specify the search criteria, whenever the filter is used
- Global filters, which can be defined at Site level (equivalent to an organization) and are available across all the projects
- Shared filters, which are defined at Workspace level (equivalent to a project) and are available across all the artifacts in the Workspace
Now, let us discuss these features of Kovair in detail:
ID & Text Search
Kovair has an 'ID & Text Search Box' which has extensive capabilities. The Search box is intelligent enough to understand whether the user is attempting a text search or an id search. This effectively means that Kovair has one single search box, which can perform both id search and text search.
When a user enters a numeric value, the system searches across record IDs and retrieves data from the system. On the other hand, when a user enters a text phrase, the system retrieves items corresponding to the matching texts.
Kovair also facilitates queries like 'Last 5' or 'Last 25', which would pull out the last 5 or last 25 entries that have been added into the system. These kinds of searches help the user in retrieving dynamic search results from the system, with the same command.
Filters in Kovair
Kovair has different types of filters which allow users to search specific sets of records and find what they are looking for. By default, Kovair retrieves the data, by virtue of the system defined filter. However, Kovair users can choose to create customized filters according to their specific needs. All that a Kovair user needs to create a new filter is an appropriate access right.
A specific type of filter that is available in Kovair is the Run Time filter, which allows users to set filter criteria in run time. You can create run time filters in Kovair based on the different fields that are available within an artifact. Once designed every time the corresponding filter would be used, the system would allow the user to define the criteria based on which the system should retrieve data. The different types of fields that are available in Kovair can be used for this purpose depending on the needs of the user.
Apart from defining filters specifically for each artifact, Kovair also has the concept of Global and Shared filters, which allow the users to create filters at the Workspace (equivalent to project) and Site (equivalent to organization) level.
Global filters are defined at Site level, whereas the Shared filters are defined at Workspace level. This effectively means that a Global filter can be used in a range of Workspaces the user has access to, and the Shared filter can be used across all the entities in a particular Workspace. The primary advantage of such filters is the fact that the creation of similar types of filters in various artifacts can be avoided.
With all these searching mechanisms prevalent in the system, Kovair provides its users with a range of efficient searching options, which in turn allows the users to use the tool more effectively.

Last week, as Theo and I were leaving a shopping center, we spotted this aboriginal man on his bicycle with a didgeridoo. I love the modern and traditional elements going on here.
So what's a didgeridoo, you ask? It's a wind instrument developed by indigenous Australians a thousand years or so ago. It's made out of a hollow tree that is cleaned out and shaped. Beeswax may be applied to the mouthpiece end and the instrument may be painted or left natural. The didgeridoo is played using a special breathing technique to continuously vibrate the lips and produce a drone.
The didgeridoo is not just a musical instrument. It's also a ceremonial instrument that traditionally only men play; women sometimes play it informally. Some indigenous Australians believe it's cultural theft for non-indigenous Australians to play or even touch it, but it's quite a popular product in tourist shops, like the ones shown above from the Queen Victoria Market.

Comparison and Contrast
Which of these things is not like the other? Use the Compare-Object cmdlet to find out.
There may be times when need to compare objects to see what is different. This if often the case when you want to capture state information and see what has changed between "snapshots." For example, you might want to troubleshoot a problem by capturing process information in the middle of the night and compare it to a known good state. Let me show you how to use the Compare-Object cmdlet, which has an alias of Diff.
First capture the current running processes:
PS C:\> $before=get-process
Then start Notepad and Calculator. Now grab an after snapshot:
PS C:\> $after=get-process
The Compare-Object cmdlet compares a source object to a reference object. In our example we want to compare before and after:
PS C:\> diff $before $after
What you'll likely see is a long list with a side indicator that tells you which item doesn't belong in the other. Remember we're dealing with a collection of process objects and even though a process like PowerShell is still running, some properties like memory utilization will have changed between snapshots. That's normal. What we want is to narrow the comparison. We can do that by selecting a property:
PS C:\> diff $before $after -property Name
Now you should see that the Notepad and Calculator properties are only found in $after. Here's one more quick example. Get all the current running services:
PS C:\> $now=get-service
Stop or start some services and take another snapshot:
PS C>\> $later=get-service
You can use Compare-Object to return more than one property:
PS C:\> diff $now $later -property Status,Name
This will show the differences based on status as well as showing the service name.
Remember, you can use the Export cmdlets to save state information and then re-create the objects using the corresponding Import cmdlet. Save a current snapshot to a variable and compare the two.
Note that this is just an intro; be sure to look at the help file for Compare-Object to find out more.

This exhibition of Modern British paintings aims to convey a spectrum of the rich and diverse artistic achievements centering on the turn of the century. It illustrates the progression of the 'Modernist' path from the Academy dominated years to the Newlyn and St. Ives group and later the Camden and Bloomsbury circles. While some of the works display the continuing appeal of the traditional and academic styles, other reflect an open attitude and gradual adoption of new Continental influences, ranging from the French Impressionism of Steer to the tubular, Leger influenced style of Roberts.
