I'm a Bit Confused about Code and Data Flash. For example, how do I count write cycles?
Latest Updated:06/16/2016
How do I count write cycles for code and data flash?
You need to make a distinction between data and code flash.
For example, on the S7G2, the first 8 blocks of code flash are 8KB in size and after that, each block is 32KB. A block is the smallest unit of erasure (write). The minimum unit you can write is 256 bytes. If you write less, the line will still have to be erased before writing to the rest of it. Even if you write only 128 bytes and then wish to access the other 128 bytes, the Flash Control Unit checks if the entire line is erased before proceeding to write. You cannot write to the same unit (256 bytes) more than once between erases, since the flash the bits can only by toggled one way (the other way is done only through erase).
Data flash is made of 64 byte blocks and the minimum you can write is 4 bytes. It follows the same rules as described above for the code flash. Renesas guarantees at least 125,000 write-erase cycles on the data flash region for the S7G2. The number of erases is the most important value when it comes to write-erase cycles. You can write to 16 4-byte chunks (i.e. 16 writes) and erase one block (64 bytes) and this is still considered one write-erase cycle.

How to get changed properties for an entity in Entity Framework
Sometimes it can be useful to find exactly which entities that have been changed before saving to the database. The most basic for check for changes it to look at the EntityState property, but this does not indicate what properties that have been changed.
To get these changes we have to use the ObjectStateManager on ObjectContext. The ObjectStateManager handles the state of all entities, and can supplied a lot of other different state information about the entities.
First we always need to get the ObjectStateEntry for the entity, this a done by calling ObjectStateManager.GetObjectStateEntry.
TestEntities entities = new TestEntities();
// Query for entity and make some changes
// To get the object state entry
var stateEntry = entities.ObjectStateManager.GetObjectStateEntry(changedEntity);
To check which properties that have changed we just do
IEnumerable modifiedProperties = stateEntry.GetModifiedProperties();
We can also get all the original and current values for the entity using
CurrentValueRecord currentValues = stateEntry.CurrentValues;
DbDataRecord originalValues = stateEntry.OriginalValues;
These two objects can are accessed by column ordinal, which you may or may not know before, but luckily there is a method to get the ordinal from a column name. To get the current and/or original value for an entity, do the following
var currentValue = currentValues.GetValue(currentValues.GetOrdinal(propertyName));
var originalValue = originalValues.GetValue(originalValues.GetOrdinal(propertyName));
Not all properties are correctly marked as changed
When using this method to generate a custom audit trail, I discovered a weird behavior in Entity Framework. Everything but the primary key, are marked as modified even though it only was "changed" to the original value. And this does not work in an audit trail.
There are two ways to solve this either manual check if a property actually has been changed, or change to generate classes for the entities. The last solution are described in my previous post, Entity Framework should only mark really updated properties as modified
The other solution is to check if the current value equals the original value using the methods described above. An example could be
var stateEntry = objectStateManager.GetObjectStateEntry(entity);
var currentValues = stateEntry.CurrentValues;
var originalValues = stateEntry.OriginalValues;
var modifiedProperties = stateEntry.GetModifiedProperties();
foreach (string modifiedProperty in modifiedProperties)
 var currentValue = currentValues.GetValue(currentValues.GetOrdinal(modifiedProperty));
 var originalValue = originalValues.GetValue(originalValues.GetOrdinal(modifiedProperty));
 if (originalValue.Equals(currentValue))
 // Value not changed
 // Value changed
1 comment:
 1. Thanks, this made it very easy to implement and prevent the annoying save when nothing changed.
 We replaced line 9 with following since some DB values are Char and we trim before saving.
 if (originalValue.Equals(currentValue) || (originalValue.GetType() == typeof(string) && ((string)originalValue).Trim().Equals(((string)currentValue).Trim())))

I am trying to understand why the order of the stabilizer group of a body diagonal of a cube is 6 rather than 3. It is clear to me that rotations about that diagonal stabilize the diagonal, by definition, and the order of this group is 3 (including the identity). So that means there must be 3 other, non-identity, rotations that stabilize this diagonal. I am terrible at geometry and I cannot think of what these others would be. I don't think that any of the rotations about $i$, $j$, $k$ can stabilize the diagonal, and I can't see 3 elements of order 2 doing this either. But then there are no elements left to consider! I am confused.
share|improve this question
There is a "swap the poles" symmetry (180 degree rotation that swaps the two ends of the body diagonal), and if you allow reflections, the "inversion" should also work. (A good answer should have a picture too :-) – Jack Schmidt Oct 17 '12 at 19:29
have you considered rotary reflections? – user39280 Oct 17 '12 at 19:32
_USER_ and dado, does the "swap the poles" symmetry correspond to a "double-rotation" about the $i$, $j$, and $k$ axis (st order of these guys is 2)? Or am I misunderstanding you? – tacos_tacos_tacos Oct 17 '12 at 20:17
_USER_: $(i,j,k) \mapsto (-j,-i,-k)$ or $a\mathbf{i}+b\mathbf{j} +c\mathbf{k} \mapsto -b\mathbf{i}-a\mathbf{j}-c\mathbf{k}$ is the rotation in terms of the coordinates. The cube itself is all $(a,b,c)=a\mathbf{i}+b\mathbf{j} +c\mathbf{k}$ such that $|a| \leq 1$, $|b|\leq 1$, $|c|\leq 1$. I still think a good answer deserves a picture, but if no-one will post one, I'll write up the linear algebra version. – Jack Schmidt Oct 17 '12 at 23:38

Do Bones Burn During Cremation?
By Staff WriterLast Updated Mar 28, 2020 1:30:38 AM ET
During the cremation process, bones are only partially burned and not completely destroyed. The process involves subjecting the remains to intense flame and heat, during which all organic matter is consumed.
The cremation process leaves behind certain bone fragments. After the remains are removed from the cremation chamber, a magnet removes any metal that was inside the body, such as implants and dental fixtures. The remaining bone fragments are then processed into fine particles and placed into a container. The cremation process generally takes about three hours and entails a careful labelling system to ensure that the remains are properly identified through the entire process.

Why Does Copper Turn Green?
Copper turns green because of chemical reactions with the elements.
For the same reason that iron rusts.
Just as iron that is left unprotected in open air will corrode and form a flaky orange-red outer layer, copper that is exposed to the elements undergoes a series of chemical reactions that give the shiny metal a pale green outer layer called a patina.
The patina actually protects the copper below the surface from further corrosion, making it a good water-proofing material for roofs (which is why the roofs of so many old buildings are bright green).
In fact, the weathering and oxidation of the Statue of Liberty's copper skin has amounted to just.005 of an inch over the last century, according to the Copper Development Association.

Herein, what is Texas sage good for?
Texas sage is a classic in the American Southwest. What is a Texas sage shrub? As a native plant, it provides cover for wild animals and birds and helps stabilize loose desert soils. This adaptable plant is drought tolerant and useful in areas with high heat and cold desert temperatures.
Subsequently, question is, how do you take care of Texas sage? Texas sage does not need rich soil to thrive and prefers dry but well-draining alkaline soil with infrequent watering. Stop watering the plant during winter. It is a water-conserving plant and only needs occasional watering. This makes Texas sage ideal for xeriscape gardens and dry soil is ideal for older plants.
Likewise, can you eat Texas sage?
It also helps that almost the entire shrub is edible some way. The blossoms, yellow or red, can be eaten raw or cooked. Their flavor is mild.
How quickly does Texas sage grow?
The Texas Sage is a fairly slow growing plant, and may take up to two years to become fully established and bloom reliably. Once established the Texas Sage is extremely drought tolerant, requires very little supplemental water, and will bloom after a good rain storm.
29 Related Question Answers Found
How much water does a Texas sage need?
Water newly planted Texas sage every five to seven days for a few weeks until it's well established, allowing the top 2 inches of soil to dry out between watering sessions. After that, rainfall should be enough in most climates. If rainfall is below average, water the plant in summer to promote flowering.
Is Texas sage poisonous to dogs?
Commonly called barometer bush or Texas sage, Leucophyllum frutescens has green or silver leaves and seasonal blooms, most commonly shaded purple. Barometer bush is not typically toxic to dogs, but can shelter allergens and other poisonous animals or matter.
Does Texas sage attract butterflies?
Bloom Time
Texas sage most often blooms after summer showers and does bloom repeatedly in waves from spring through fall, especially after rains moisten the soil. Other benefits of Texas sage are its interesting foliage and its ability to attract butterflies and other beneficial insects.
Do bees like Texas sage?
Texas Sage Plant Features
The flowers attract bees, butterflies, and other polliantors.
Does Texas sage loose leaves in winter?
ANSWER: Leucophyllum frutescens (Cenizo), or Texas sage, is a dry land plant that responds very strongly to weather conditions. It often loses leaves following a cold winter. Texas sage can be pruned severely if desired without permanent damage.
Is Texas sage an evergreen?
As you might have guessed, Texas sage originated in Texas, but also in New Mexico, and across the border, in northern Mexico. It is an evergreen shrub, with grayish-green leaves and purple flowers. Texas sage also goes by the names of Texas Ranger and Silverleaf. It's a perennial which will bloom on its own every year.
Can you cut back Texas sage?
If left to grow naturally, Texas sage develops uneven branches and an unruly appearance. Pruning is not necessary, but an occasional trim keeps the shrub looking neat. Ideally, pruning should occur in late winter before Texas sage produces new growth.
Why is my Texas sage not blooming?
Texas Sage thrives in full sun and well-drained alkaline soil. They will tolerate a bit of shade, but too much shade will result in leggy plants that don't bloom heavily. Supplemental water in summer will help plants grow faster and bloom more, but over-watering or poor drainage will kill Texas sage quickly.
What is Cenizo good for?
Comments: Cenizo is popular for xeriscaping in Texas - it is a good choice for foundation planting and hedges, and is useful as a windbreak barrier or a screen. It is not unusual to see Cenizo as a sheared hedge, although light pruning to maintain a more natural shape may result in a healthier shrub.
What is Purple Sage good for?
Highly aromatic, Purple Sage is the most effective medicinal variety of Sage but stands cold the least. It can be made into teas to aide in digestion, used as an anti inflammatory agent for insect bites and can relive chest colds and congestion.
Can you cook with Purple Sage?
Purple sage can be used in place of common garden sage or when an added pop of color is desired. Purple sage develops optimal flavor when cooked in fat such as butter, olive oil, or bacon. Pan fry fresh Purple sage leaves until crispy for a uniquely colored garnish for quiches, pastas, risotto or other dishes.
What does it mean when purple sage blooms?
It tells you when it may rain! A drought-tolerant, evergreen shrub, this pretty, silver-leafed bush can bloom tubular-shaped blossoms that are a bold purple in color. Actual rainfall may not occur, but the plant is sensitive to changes in barometric pressure and humidity, and therefore it blossoms.
How do you prune a Texas Ranger?
Prune the shrub in the late winter or early spring when it is dormant. Cut out any dead or broken branches with a pair of pruning shears. Make each cut 1/4 inch above an outward-facing leaf bud, lateral branch or branch base. Remove any crossing branches that rub against other limbs.
Why is my Texas sage yellow?
How do you transplant Texas sage?
The shrub can get established and form a good root system during the cool, wet season when conditions are mild.
 1. Clear the planting area and remove rocks, weeds, roots and sticks.
 2. Soak the container the Texas sage is in 24 hours before planting.
Is Texas sage drought tolerant?
Very drought tolerant. Requires excellent drainage. The Texas sage is a fairly slow-growing plant, and may take up to 2 years to become fully established and bloom reliably. Once established, the Texas Sage is extremely drought tolerant, requires very little supplemental water, and will bloom after a good rain storm.
What does Texas sage look like?
Handsome and hardy, Texas sage is an outstanding South Florida landscape choice with its silvery foliage, purple flowers and drought-tolerant nature. The lavender to purple blossoms appear on and off all year amidst small, soft, silver or gray-green leaves.

How to make the mouse left-handed in Mac OS X
This page explains step-by-step how to make the mouse left-handed in Mac OS X. Unless you have a single-button mouse, your mouse is set up for a right-handed person by default, with the primary button on the left. However, you can swap the function of the mouse buttons from the default left click, so that a right click is instead used for selection and dragging. You'll just need to remember to press the opposite button to what is called for when you are following instructions (for example, if you are requested to right-click on something).
Note: The following abbreviations for keys on the Mac are used: Ctrl is used for the Control key, Apple is used for the Command key, and Alt is used for the Option key. For keyboard access, make sure 'Full keyboard access' is turned on - you can turn it on or off by pressing Ctrl + F1 at any time.
Step 1: Open the 'Keyboard & Mouse' window
Make sure you are in 'Finder'. If necessary, press Apple + Tab to cycle through the open applications until you return to 'Finder'.
Click on the 'Apple' icon on the menu bar or press Ctrl + F2.
Click on 'System Preferences', as shown in Fig 1, or press the down arrow key to highlight it and then press Enter.
In the 'System Preferences' window (shown in Fig 2), click on the 'Keyboard & Mouse' icon, or press Tab repeatedly (you might need to press Ctrl + F7 first) to cycle through the icons until the 'Keyboard & Mouse' icon is highlighted and then press the Spacebar.
Step 2: Swap the primary and secondary mouse buttons
In the 'Keyboard & Mouse' window, make sure the 'Mouse' tab is selected. If it is not, click on it, or press Ctrl + F7 to highlight one of the tabs and then press the left or right arrow key to select it. Depending on the mouse you are using, you will see something like the window shown in Fig 3, which shows the default button settings for a right-handed person.
Click on the drop-down button to the right of the picture of the mouse and select 'Primary Button' from the list, or press Tab until the drop-down button is highlighted and then use the up and down arrow keys to scroll through the options.
Click on the drop-down button to the left of the picture of the mouse and select 'Secondary Button' from the list, or press Tab until the drop-down button is highlighted and then use the up and down arrow keys to scroll through the options.
(If you prefer to use your mouse as if it had a single button, select 'Primary Button' from the drop-down lists to both the right and the left of the picture of the mouse.)
You can also change the function of the side buttons and scroll ball (or scroll wheel), if your mouse has these.
When you are finished, click on the window's red close button or press Apple + W.

Approval cutoff
The approval cutoff, approval threshold or neutral preference level is an option that may be used with a ranked ballot. It allows the collection of the information necessary to create an Approval ballot. Note that the concept of an approval threshold can also be used in a theoretical sense[1] i.e. if a voter is deciding who to vote for in Approval voting, they may do so by thinking about their ranked preferences and mentally deciding who their least-preferred candidate is that they consider acceptable.
Specifying a neutral preference level indicates that candidates above a certain rank have positive preference, while candidates below that rank have negative preference. Positive preference is equivalent to an approval vote, while negative preference receives no approval vote.
Sometimes candidates at the approval threshold are also considered approved, instead of being treated neutrally. There may be a loose terminological tendency to use "approval cutoff" to indicate the neutral preference level option, and "approval threshold" to indicate this option.
When a method uses a ranked ballot with approval cutoff, the usual procedure is that the neutral preference level is set below all ranked candidates, and above unranked candidates.
A voter can set the approval cutoff above the default level by ranking an extra "Neutral Preference" candidate.
A voter may decide to set the neutral preference level between some ranked candidates in order to indicate that
 - among the non-approved candidates, some are more preferred than others.
 - the ranking of candidates above and below the line is not as important as having a candidate above the line defeat all candidates below the line.
It is also possible to consider fractional approval thresholds i.e. one threshold which gives candidates 100% approval, a second threshold that gives them 90%, etc. Thesr thresholds would be consecutive, so for example, a voter giving their 2nd choice 100% approval but their 4th choice 90% approval would also give their 3rd choice 90% approval. This would allow the collection of rated ballot information.
The approval threshold is usually indicated with a |, which can be visually highlighted by putting space after it. Example:
30: A>B| >C>D>E
This means 30 voters approve both A and B, but not C, D, and E.
Another way to implement the approval threshold in practice would be to let voters mark approval of the candidates directly (similar to Approval voting) alongside their rankings, and then for whichever of the approved candidates the voter ranked lowest, all candidates ranked equal to or higher than that candidate are also considered approved.
A preference-approval is a preference order that combines preference with approval. It can contain either weak or strong preferences. A complete preference-approval is a total preference order.
Rationality RestrictionsEdit
Here are some rationality restrictions on preference-approvals. Suppose there exists two alternatives, x and y:
1) If a given voter prefers x over y, and approves y, then she must approve x.
2) If a given voter prefers x over y, and does not approve x, then she must not approve y.
3) If a given voter is indifferent between x and y, and approves x, then she must approve y.
4) If a given voter is indifferent between x and y, and does not approve x, then she must not approve y.[clarification needed]
Note that these same restrictions can be applied to rated ballots or fractional/weighted approval thresholds i.e. a voter who prefers one candidate more than or equally to another must give the first candidate at least as high a score or degree of support as the second. The KP transform can be used to model this in terms of Approval ballots.
He are some expressions of preference-approvals and translations into natural language:
|x>y: "The voter prefers x over y, but approves neither." |x=y: "The voter is indifferent between x and y, but approves neither."
x|y: "The voter prefers x over y, but only approves x."
x>y|: "The voter prefers x over y, but approves both."
Steven Brams and Peter Fishburn used preference-approvals in their book "Approval Voting" in 1983, though it probably was used before then.
There are 2, 8, 44, 308,... different preference-approvals for 1, 2, 3, 4,... candidates (Sloan's A005649).
Total preference orderEdit
A total preference order is a complete preference-approval. In other words, it is a preference-approval that contains all alternatives competing in a given election.
Sometimes an approval threshold is also indicated using an ">=", for example, A>B| can be written as A>=B.
The logic of the approval threshold is that if a voter approves a candidate, and they prefer some other candidate(s) over the candidate they approved, then it's very likely that voter would also approve of those more-preferred candidates if voting with an Approval ballot, since otherwise they'd be giving more support to a candidate they prefer less than the candidates they'd be disapproving.
An approval threshold can be used in the context of rated methods as well. This can be useful for cardinal PR, since it could be possible to allow, for example, a Green Party voter to approve both Green Party candidates and Democratic candidates, using the approvals to ensure one of those preferred candidates wins, and then score the candidates in such a way as to maximize the odds that of the preferred candidates, one of the Green Party candidates wins.
It is generally assumed that a voter who doesn't indicate an approval threshold at least approves all of their 1st choice candidates. So if they had voted A=B=C>D>E, then A, B, and C would be considered approved.
See Smith//Approval for an example of the use of the approval threshold.

The last time I checked, most sugar is really dry (unless it's something like brown sugar). So why is it categorized as "wet"?
Sugar is not really a wet ingredient, it's just treated as one in certain types of baking (i.e. cakes).
When making a cake or other "fluffy" baked good, you want a fairly small amount of gluten to be produced, otherwise you'll get a chewy texture instead, and you definitely don't want a cake to be chewy like bread.
Dissolving sugar in the water inhibits the gluten-forming proteins. It's a method (actually, the method) of adding more liquid to the mix without getting a tough, chewy cake. It is for this reason that sugar is considered a "wet ingredient" - because the process only works properly if you add it with the water, not with the other dry ingredients.
It's even possible for sugar to be a dry and wet ingredient in the same recipe; you might add just enough sugar to the water to get the right texture, and add more to the dry ingredients for further sweetening.
I'm not sure what the context is, but I dug up this article that mentions sugar being a wet ingredient when baking certain items such as cake. A quick summary from the article:
"...the general idea is that Sugar and Water are Best Friends Forever, and they swear that nothing will ever separate them."
I'm guessing basically sugar is used with water (as opposed to being kept undissolved as a solid) so much that this is why it is considered 'wet,' at least in the context the article talks about.
Hope this helps!

Lay Poisonous Eggs
Answer: Taste with Their Legs
Some species of butterflies have a rather curious talent that we should all be glad humans do not possess: they can taste via their legs. These butterflies have special hairs on their legs called gustatory sensilla that are the same specialized hairs found on their mouths and antenna that function as taste receptors.
How does tasting via their legs help the butterflies? By tasting the leaves they alight on, they can immediately determine if the plant is a suitable host for their eggs. In a world where predators are many and dallying on a plant is dangerous, the ability to instantly determine if the plant they've landed on is hostile or an ideal spot to leave their young offers a huge advantage.

Self-reinforcing Mechanisms in a Multi-technology Industry: Understanding Sustained Technological Variety in a Context of Path Dependency
Artikel i vetenskaplig tidskrift, 2015
This paper studies self-reinforcing mechanisms in multi-technology industries, i.e. industries in which technological lock-in does not occur and several technologies continue to coexist. The purpose of this paper is to investigate what kind of self-reinforcing mechanisms can be present in such industries and explain how multiple paths can coexist and interact in a context of self-reinforcement and, ultimately, path dependency. Building on the empirical example of the lighting industry, the paper shows that all previously recognized types of self-reinforcing mechanisms can be present in a multi-technology industry. However, in addition to the path-internal positive feedbacks and cross-path negative externalities identified in single-path settings, multi-technology industries also experience positive cross-path externalities that create a symbiotic relationship between alternatives and allow for the reproduction of the same development pattern across technologies. Due to the existence of such non-negative technology interactions, multi-technology industries can be path dependent while still retaining technological variety.

5.7. Scalar Coordinate Variables
When a variable has an associated coordinate which is
single-valued, that coordinate may be represented as a
scalar variable. Since there is no associated dimension
these scalar coordinate variables should be attached to
a data variable via the
Under COARDS the method of providing a single valued coordinate was to add a dimension of size one to the variable, and supply the corresponding coordinate variable. The new scalar coordinate variable is a convenience feature which avoids adding size one dimensions to variables. Scalar coordinate variables have the same information content and can be used in the same contexts as a size one coordinate variable. Note however that use of this feature with a latitude, longitude, vertical, or time coordinate will inhibit COARDS conforming applications from recognizing them.
Once a name is used for a scalar coordinate variable it can not be used for a 1D coordinate variable. For this reason we strongly recommend against using a name for a scalar coordinate variable that matches the name of any dimension in the file.
Example 5.11. Multiple forecasts from a single analysis
dimensions: lat = 180 ; lon = 360 ; time = UNLIMITED ; variables: double atime atime:standard_name = "forecast_reference_time" ; atime:units = "hours since 1999-01-01 00:00" ; double time(time); time:standard_name = "time" ; time:units = "hours since 1999-01-01 00:00" ; double lon(lon) ; lon:long_name = "station longitude"; lon:units = "degrees_east"; double lat(lat) ; lat:long_name = "station latitude" ; lat:units = "degrees_north" ; double p500 p500:long_name = "pressure" ; p500:units = "hPa" ; p500:positive = "down" ; float height(time,lat,lon); height:long_name = "geopotential height" ; height:standard_name = "geopotential_height" ; height:units = "m" ; height:coordinates = "atime p500" ; data: time = 6., 12., 18., 24. ; atime = 0. ; p500 = 500. ;
In this example both the analysis time and the single pressure level are represented using scalar coordinate variables. The analysis time is identified by the standard name "forecast_reference_time" while the valid time of the forecast is identified by the standard name "time".

Looking at the source, it could be that Mechanize is supposed to work like that. It forces the form method to uppercase when it fetches the form; you are expected to supply the method in uppercase when you want to match it. You might ping the mechanize person(s) and ask them if it's supposed to work like that.
Here in Mechanize.submit, it forces the form method to uppercase before comparing it:
def submit(form, button=nil, headers={})
 case form.method.upcase
 when 'POST'
 when 'GET'
and here again in Form.initialize, the method is forced to uppercase:
 def initialize(node, mech=nil, page=nil)
 _USER_ = (node['method'] || 'GET').upcase
But in page.rb is the code where mechanize is matching a form (or link, base, frame or iframe) against the parameters you gave, the parameter you passed in is not forced to uppercase, so it's a case sensitive match:
 def #{type}s_with(criteria)
 criteria = {:name => criteria} if String === criteria
 f = #{type}s.find_all do |thing|
 criteria.all? { |k,v| v === thing.send(k) }
 yield f if block_given?
Well, it's a case sensitive match if you pass in a string. But if you pass in a regex, it's a regex match. So you ought to be able to do this:
login_form = page.form_with(:method => /post/i)
and have it work fine. But I would probably just pass in an uppercase String, send the Mechanize person(s) an email, and move on.

An exploratory study of Nantou Ancient Village revitalisation focusing on visual, cognitive and structural aspects
MetadataShow full item record
In the absence of spatial diversity, there is a need for additional elements that will enable the recognition of the space in which we are. These elements are landmarks. In order for a certain thing to be considered a landmark, it must be unique and recognisable either by its properties (size, shape, colour, materialisation, etc.) or by the location where it is located in space. Landmarks and zones with a strong character provide a strong identification of the space with its peculiarity. This paper analyses the identity of the urban settlement of Nantou Old Town as a historical cluster located in the attractive location in the Nanshan District of Shenzhen City, with over 800 residential and commercial units. The study was conducted experimentally on a number of respondents who are regular or occasional consumers in Nantou settlement, through a closed questionnaire, from which we got answers to the initial questions: how successful is the revitalisation of this cultural-historical settlement, what are the landmarks, how simple is orientation through the settlement and what method is most common in wayfinding (landmark or navigation app), does a consumer's choice in wayfinding device and landmark physical characteristics (colour, texture and form) depend on personal dimensions (gender, age, educational level and familiarity with environment).

PVC water belt use precautions
High temperature resistant hose
It is also a kind of steam hose, which is mainly used to transport hot water with a temperature greater than 100 degrees and less than 180 degrees. We all know that the maximum temperature of water at a standard atmospheric pressure is 100 degrees, but if the pressure of the closed pipe is more than 100 degrees, the hose must be pressurized and temperature. The higher the pressure, the greater the pressure. High-temperature water-receiving hoses When selecting the type, the pressure of the hose must be taken into consideration to prevent the steam hose from rupturing or injuring the equipment due to too much pressure. It is preferable to use a threaded joint or a high pressure joint to ensure the safety of the hose.
High temperature resistant acid hose
Because the material of the steam hose is generally EPDM rubber or EPDM rubber, this rubber has good corrosion resistance, so the steam hose can also be used to transport various acids with high temperature, such as hydrochloric acid and sulfuric acid.

Food is the basic source of nutrition to both humans and animals. Lack of it leads to hunger which can be tracked by a pawn's food meter known as saturation and a long excessive deprivation leads to starvation.
For a more in-depth guide to farming and producing food, see Food production.
Raw Food
For a list of raw food items, see Raw food.
Food found in its natural stage is raw, fruits can be consumed without cooking but vegetables and meat will taste better for the colonist when prepared. Raws can still be consumed without being heated but causes the Ate raw food thought with a -7 mood penalty. Eating raw food restores 0.05 saturation each. Foods cooked at an electric stove, fueled stove or campfire turn into meals, later on it can be processed at the nutrient paste dispenser as well.
Raw food can be obtained from a variety of sources:
As of Alpha 15 (August 28st, 2016), there is a message telling you when food has spoiled.
Food will be wasted if left unattended (except for beer) by two factors: exposure and high temperature.
 - Storage in temperature above 0°C will spoil over time as well, though temperatures below 10°C will slow down spoiling. A freezer room can be created by placing at least enough Coolers in proportion to its size, the bigger the storage the more coolers required. In the early game, this can pose a threat if located on warm biomes.
Note that freezing temperatures alone does not prevent deterioration of food. For example: a raider is killed and drops his/her fine meal outdoors. That meal will still decay from exposure.
Once spoiled, food will vanish and can never be recovered. However, food can be eaten at any stage before spoiling with no visible mood effect.

Using Spring Connectors in SOLIDWORKS Simulation to Reduce Complexity in Your Analysis
By Paolo Olmos
I recently worked on a customer project which involved answering the question, "How can I represent complex sub-assemblies or components that are part of a larger assembly using SOLIDWORKS Simulation?" The customer wanted to include ball screws and linear rails. These sub-assemblies include bearings, threads, and complex mounting geometry that would require a significant amount of time and effort to setup - and a significant amount of time to solve. Additionally, if I were to miss an element in the setup, the analysis could fail or the results may be invalid. One way to simplify an analysis that involves complex sub-assemblies or components is to replace them with spring connectors. Replacing components with spring connectors allows you to:
 - Reduce the number of components that need to be meshed, improving solve time
 - Simplify the analysis setup, reducing the overall time necessary to execute the analysis
While maintaining the inherent stiffness of the components you remove by replacing them with an equivalent spring stiffness. As an example, let's take an assembly made of 2 plates with a spring in the middle. Including the spring in a linear static analysis with a 100 lbf load applied, the results show a displacement of 0.282 inches. To use a spring connector in this situation, the spring component is suppressed and replaced with a virtual spring that uses the stiffness data you have for the modeled spring. As you can see in the screenshots below, we can get the same displacements as the analysis that included the modeled spring.
Spring Connector
Right: Results With Spring, Left: Results With Spring Connector.
Comparing the setup and solve time between the two studies:
 - The setup time was short for both studies, but imagine if the spring was a more complex sub-assembly or component. It would require time to define contacts, material, and fixtures for all the elements in the sub-assembly or component. The setup time could be substantially longer.
 - The solve time for the actual spring took 6 seconds to solve versus 2 seconds for the spring connector analysis.
A couple of other things to consider when using spring connectors:
 - Make sure that the face selected for one body shares a common projected area on the face selected for the other body. If you don't, SOLIDWORKS Simulation cannot create the spring and will display an error when you try to run the analysis. In the example above, the faces selected had the same area and were directly overlapping when looking at the top view.
 - You can create split lines to separate the faces of each body in order to create a common projected area between them. In the example above, this technique would have been required if the spring was significantly smaller than the plates.
As you can see in this brief overview, spring connectors can help you obtain accurate results, while saving you time to setup and solve your analysis. Keep a look-out at this space for a follow-up blog article that covers using spring connectors to represent the ball screw and linear rail assemblies mentioned earlier, or watch my webinar: SOLIDWORKS Simulation - Representing Ball Screws and Linear Rails in Your Analysis.

The code and value together are unique, and a composite key is created containing them both.
We load in reference data from an excel spreadsheet, and at some point, there was a code and value pair added to a reference data type which matched exactly with a code and value pair from another reference data type. Attempting to add the second code value pair resulted in a unique key violation.
I needed to add the discriminator column into the composite key. If you're using auto mapping, you'll need to add an auto mapping override. Below is an example of creating a composite key containing the code, discriminator and value columns.
public class ReferenceDataAutoMappingOverride : IAutoMappingOverride
 public void Override(AutoMapping mapping)
 const string uniqueKeyName = "UK_ReferenceData_discriminator_Code_Value";
 mapping.Map(refData => refData.Code).UniqueKey(uniqueKeyName);
 mapping.Map(refData => refData.Value).UniqueKey(uniqueKeyName);

Zend Framework 101: Zend_Log
Creating Your First Logger
To begin, I'll show you how to create a basic file-system logger. To achieve this we must instantiate the
Zend_Log class, then add a writer to this object. We will use a writer that writes log messages to the file system.
The class we use to write log messages to the file system is
Zend_Log_Writer_Stream. This class accepts the path where the log messages should be written to as the first argument to the constructor.
Listing 1 shows an example of creating the logger and adding the writer to it. You can either add the writer when instantiating
Zend_Log (such as
new Zend_Log(new Zend_Log_Writer_Stream(...))), or as shown in the following listing.
require_once('Zend/Log.php'); require_once('Zend/Log/Writer/Stream.php'); $logger = new Zend_Log(); $writer = new Zend_Log_Writer_Stream('sample.log'); $logger->addWriter($writer); $logger->log('sample message!', Zend_Log::INFO);
The above listing concludes by calling the log() method on the
Zend_Log object. This records a message to the log. Listing 2 shows an example of how the log file appears after this code is run.
$ cat sample.log 2009-04-11T14:47:20+09:00 INFO (6): sample message!
In the next section I'll cover the recording of events in greater detail.

Using your existing pattern - OnClosing + AW_HIDE does it in reverse.
protected override void OnClosing(CancelEventArgs e)
 AnimateWindow(this.Handle, 500, AW_ACTIVATE | AW_SLIDE | AW_HOR_NEGATIVE | AW_HIDE);
share|improve this answer
Why don't use simply Form.Location property.
Increase or decrease it's relative values to achieve sliding animation effect you want.
share|improve this answer
This library might be able to do what you want.
Example code from the site, which could, in your case, be placed in the Closing event.
Transition t = new Transition(new TransitionType_EaseInEaseOut(2000));
t.add(pictureBox1, "Left", 300);
t.add(pictureBox1, "Top", 200);
Once you've done the animation, you can use the TransitionCompletedEvent event to hide the form. (or you could animate the Opacity property of your form)

Meaning: highland; The name Elam is an Assyrian word meaning "high."
the son of Shem (Gen. 10:22), and the name of the country inhabited by his descendants (14:1, 9; Isa. 11:11; 21:2, etc.) lying to the east of Babylonia, and extending to the shore of the Mediterranean, a distance in a direct line of about 1,000 miles
"The inhabitants of Elam, or 'the Highlands,' to the east of Babylon, were called Elamites. They were divided into several branches, speaking different dialects of the same agglutinative language. The race to which they belonged was brachycephalic, or short-headed, like the pre-Semitic Sumerians of Babylonia.
"The earliest Elamite kingdom seems to have been that of Anzan, the exact site of which is uncertain; but in the time of Abraham, Shushan or Susa appears to have already become the capital of the country. Babylonia was frequently invaded by the Elamite kings, who at times asserted their supremacy over it (as in the case of Chedorlaomer, the Kudur-Lagamar, or 'servant of the goddess Lagamar,' of the cuneiform texts).
"The later Assyrian monarchs made several campaigns against Elam, and finally Assur-bani-pal (about B.C. 650) succeeded in conquering the country, which was ravaged with fire and sword. On the fall of the Assyrian Empire, Elam passed into the hands of the Persians" (A.H. Sayce).
This country was called by the Greeks Cissia or Susiana.

One of the configuration variables we can find in the solrconfig.xml file is maxBooleanClauses, which specifies the maximum number of boolean clauses that can be combined in a single query. The question is, do I have to worry about it when using filters in Solr? Let's try to answer that question without getting into Lucene and Solr source code.
Let's assume that we have the following query we want to change:
q=category:1 AND category:2 AND category:3... AND category:2000
Sending such a query to the Solr instance with the default configuration would result in the following exception: "too many boolean clauses". Of course we could modify the maxBooleanClauses variable in solrconfig.xml file and get rid of the exception, but let's try do it the other way:
Let's change the query to use filters
So, we change the above query to use filters – the fq parameter:
q=*:*&fq=category:(1 2 3... 2000)
We send the query to Solr and … and again the same situation happens – exception with the "too many boolean clauses" message. It happens because Solr has to "calculate" filter content and thus run the appropriate query. So, let's modify the query once again:
Final query change
After the final modification our query should look like this:
After sending such a query we will get the search results (of course if there are documents matching the query in the index). This time Solr didn't have to run a single, large boolean query and that's why we didn't exceed the maxBooleanClauses limit.
To sum up
As you can see the answer to the question asked in the begining of the post depend on the query we want to run. If our query is using AND boolean operator we can use fq parameter because multiple fq parameters are concatenated using AND. However if we have to use OR we would have to change the limit defined by maxBooleanClauses configuration variable. But please remember that changing this limit can have a negative effect on performance and memory usage.

text: The basic requirement for the successful deployment of a mobile augmented reality application is a reliable tracking system with high accuracy. Recently, a helmet-based inside-out tracking system which meets this demand has been proposed for self-localization in buildings. To realize an augmented reality application based on this tracking system, a display has to be added for visualization purposes. Therefore, the relative pose of this visualization platform with respect to the helmet has to be tracked. In the case of hand-held visualization platforms like smartphones or tablets, this can be achieved by means of image-based tracking methods like marker-based or model-based tracking. In this paper, we present two marker-based methods for tracking the relative pose between the helmet-based tracking system and a tablet-based visualization system. Both methods were implemented and comparatively evaluated in terms of tracking accuracy. Our results show that mobile inside-out tracking systems without integrated displays can easily be supplemented with a hand-held tablet as visualization device for augmented reality purposes.

How To Make Your Climbing Gear Last Longer
How to make your climbing gear last longer Redpoint Climbing Australia Cofounder Jack Tho Trad Climbing at ArapilesClimbing shoes and rope are the most frequently used climbing gear that also endures the most wear and tear. Here are some tips on how to look after your climbing gear so that they may last longer.
Climbing Shoes
 1. Practice your footwork. The wear and tear on your climbing shoe rubber can tell you a lot about your climbing technique. If you see abrasions on the tip of your toe rubber, you may be dragging your foot along the wall and readjusting rather than placing your foot correctly the first time. Try improving the precision of your footwork by climbing slowly during warm up, consciously thinking about exactly where you want your foot to land before placing it on the hold. Practicing downclimbing can also help improve your footwork as you tend to weight your toes when leading with your feet.
 2. Opt for durable and stiff rubber. Most climbers will wear down their first pair of shoes quite quickly due to scuffles with the wall. Avoid buying any high end shoes with sticky and soft rubber (e.g. Vibram XS grip 2) because it will wear down and need replacing very fast. Instead, opt for stiffer and thicker rubber, minimum 4mm for the rubber sole. You can roughly gauge the stiffness of the rubber by pressing your nail against the bottom of the rubber shoe sole. Check out this article to find out how much you should be spending on climbing shoes.
 3. Air out your shoes after every climb. This means taking them out of your gym bag and leaving them near a door or window after you get home from climbing. Avoid direct sunlight as this may deform the rubber.
 4. Know when it's time to resole your climbing shoes. After every climb, check that the rubber soles under the toes still make an edge with the rand. If the edge where the rubber sole meets the rand is round and smooth, get your shoes resoled. Most climbers wait until the rand breaks through. Patching up the rand (or toe cap) typically costs 40-60% more than just the soles. Arapiles Resoles is one of the best, however they don't always accept jobs via mail. Big John Resoles in NSW accepts jobs via mail, including interstate.
Climbing Rope
 1. Keep your rope away from dirt and grime. Small debris such as dirt and sand can damage the sheath of the rope over time. A cheap alternative to a rope bag is the Ikea blue carry bags.
 2. Beware of UV and heat. Do not store your rope in the trunk of your car on hot summer days. Heat over 30 degree Celsius can break down the fibres.
 3. Clean your rope once a year, or when it looks dirty. The easiest way to do this is in a bathtub with warm water and some rope cleaner or hand soap. Avoid anything abrasive such as detergents and high-pressure hoses. Soak your rope in the soap water and run your hands along the length of the rope. You'll need to do this twice to rinse the soap out the second time. Allow the rope to air dry.
 Climbing ropes cost from $250 to $450 and climbing shoes cost from $120 to $260. It definitely pays to look after your climbing gear and make them last as long as possible.


RTX shows bigger calculation difference with CPU than GTX?
I have source codes to solve 2-dimensional shallow water equation using C++ and Cuda 11.2.
I have tested the exe file on GTX970, GTX1080Ti, RTX2070, RTX2080, RTX2080Super.
The results of calculation difference with CPU are as below.
GPU ====> Max. value of calculation result difference with CPU
GTX970 ====> 0.001
GTX1080Ti ====> 0.001
RTX2070 ====> 0.204
RTX2080 ====> 0.261
RTX2080Super ====> 0.221
The question is "Why RTXs have bigger difference than GTXs? "
Are there any build options for RTXs?
I use Visual studio 2019, Cuda Toolkit 11.2, and C++.
I applied sm_52 and compute_52( or sm_75 and compute_75), and "Use Fast Math : false" options.
My PC OS is Windows10 64bit.
Please help me.
calculation difference with CPU
This is not a valid measure of correctness or accuracy.
Since code generation has an architecture-dependent component, on both CPUs and GPUs, numerical differences can result. For example, the compiler may re-arrange code to increase instruction-level parallelism, or apply fusion of FMUL and dependent FADD into an FMA (fused multiply-add) differently, or some math functions may have slightly different accuracy within the stated accuracy bounds.
If you want to assess accuracy, the easiest (but not entirely foolproof) way is to compute reference results in (much) higher precision, then compare against that.
If you merely need the issue to go away, try compiling with -fmad=false. Note: this will in all likelihood decrease both performance and accuracy of the GPU implementation.
Thanks njuffa,
You are right, it is not about accuracy.
So I have changed the title of this issue.

New title: RTX shows bigger calculation difference with CPU than GTX?
I think its unlikely that anyone can give you a complete answer unless either you provide a complete code example, or someone decides to write a lengthy tutorial for you.
The only "build options" specific to RTX that come to mind are the ones you already mentioned: it's always good practice to compile for the architecture(s) you intend to run on, e.g. compute_75/sm_75 for a cc7.5 GPU.
Here is a brief tutorial. I would say there are two general categories of issues here.
 1. Those arising from machine calculation methods. For example comparing float to double, or with or with FMA contraction, are a couple examples. Such differences can easily give rise to differences in results, whether we are talking about comparing CPU to GPU or some other comparison. In addition, other more complex operations such as sin(), cos(), and other "library" match functions may simply be implemented differently on two different "machines" giving rise to different results.
 2. Those arising from order of operations (algorithm calculation methods). Floating point operations don't always have all the characteristics of basic math operations that we learned about in grade school/middle school. If you compare a serial algorithm/realization to a parallel algorithm/realization, its often the case that the math doesn't get done in exactly the same order. This can give rise to differences. A possible item to read here is this floating point whitepaper
Because the two GPUs you mention generally have different sizes (e.g. differing numbers of SMs, for example) a nice ninja-tuned parallel reduction that scopes out the size of the GPU being run on, then uses e.g. a grid-stride loop to size the grid to match the GPU, and then doing a parallel reduction, will likely give at least slightly different results depending on the GPU it is run on.
I doubt that is actually the issue in your case; I don't know what the issue is in your case. You're welcome to discuss it further, but I'm unlikely to provide any further response unless you provide a short, complete example that demonstrates the issue.
There are many questions on various forums that fit this general description (CPU/GPU differences), here is one example. Yes, I'm aware that one doesn't specifically focus on GPU-GPU differences. Here is one that discusses GPU-GPU results differences, in a general way. I'm sure you can find others.
Thank you, Robert_Crovella
I will review my codes carefully about your comments.
And if I have any positive results, I will let you know.
Thank you, Robert_Crovella.
I have reviewed my codes in detail, and it seems I have found the solution.
The summaries of my review are as follows.
 1. __syncthreads() function acted more strictly in RTX than GTX.
 (e.g. At a __syncthreads() in a "if" statement, RTX was hung but GTX was not.)
 2. GTX was more sensitive on the value of thread per block (TPB).
 When the TPB was changed, the calculation results from GTX were less sensitive than RTX.
 (** My calculation includes iteration process (implicit method).)
 3. When I applied larger value of TPB(e.g. 32, 64, 128, 256, 512), the calculation results from RTX became closer to the results using CPU. I think, this may be, larger TPB can sync more control volumes in a block even though cudaDeviceSynchronize() is not applied.
 (** The control volume is minimum calculation unit when using finite volume method (FVM).)
 4. When I applied TPB as 256 or a larger value to RTXs and 32 to GTXs, the calculation results from all the GPUs were very close to the results using CPU.
 (** In my first posting of May 27, TPB 32 was applied to all RTXs and GTXs.)
Again, thank you for your comments and encouraging.


NHibernate Caching: The Secong Level Cache Space Is Shared!
time to read 3 min | 439 words
Let us assume that you have an architecture that demands that you'll have a database per client (quite common, by my experiance), but the application layers are the same. This is usually done for reasons of security and/or scalability. So there is no way a client can get information for another client.
This is fairly simple to handle with NHibernate, you just create a session factory per each client. This is actually an advantage, since you can start playing with the implementations of the classes for each client. (Yes, you are reading me correctly. In this case, it possible to turn NHibernate into an Inversion Of Control container).
The issue turns up when you have caching turned on. Assuming you have an entity of the same type with the same identifier in two of the databases, you may very will mix the data when it is cached. NHibernate maintain a single second level cache per session factory, so you are supposed to be safe from this. The problem is that the cache space is shared (and it has to be shared).
Let us take an example of an Employee object with id of #5, which exist in both IniTech and Fuzbar databases. When the employee instnace is loaded and put in the cache, the cache key that is used looks something like: "NHibernate:Entities.EmployeeManagement.Employee:5@5". Now, when we try to load an employee from the second database, we first lookup in the cache, finding that there is an instance there, because the cache keys matches.
This is happening because the cache space (so to speak) is the same space for all the caching strategies. For SysCache, it is the ASP.Net cache that is used for the cache space. For distributed caching, Memcached is used. In both cases, if the same cache key is generated, the information will be returned even if the key was actually inserted by another session factory.
In this sceanrio, I solved the issue by modifying the SysCacheProvider to be aware of the current database, and insert the current database name to the cache key. This solved all the issues in one stroke.
The JIRA issue for this is here. I was surprised to learn that I was the first to encounter this, and in the comments to the JIRA issue, I found that indeed I wasn't the first. :-)
The issue is solve by specifying cache region prefix in the session factory configuration, but the functionality wasn't ported to NHibernate yet.

I am currently trying to retrieve a unique device identifier. Here is my code:

var reader = Windows.Storage.Streams.DataReader.fromBuffer(;
reader.unicodeEncoding = true;
var identifier = reader.readString(reader.unconsumedBufferLength);
But it raises following error:
The operation attempted to access data outside the valid range.
How can I retrieve the size of my string? I also tried to use, but result is the same.

Depending on what you are using it for, you should be aware that the id will change, possibly frequently on some devices. You should probably use a subset of the constituent components in the id if you need to (more) reliably identify the device again later. Docs here: – Endophage Nov 9 '12 at 21:14

I can't try to replicate what you're doing at the moment, but you might try reading it as bytes into array like this:
var array = new Array(;
And then convert the array to a string for the identifier.
See these posts for examples:

Your solution works perfectly. Thanks for your help, even if I still can't get the reason why they return a IBuffer object instead of a simple string. But sure they got one. ;) – Jonathan Petitcolas Aug 22 '12 at 8:36

Letter from Africa: Why age is just a number in Ghana
By Lorlornyofm May 14, 2017 14:02
Letter from Africa: Why age is just a number in Ghana
In our series of letters from African journalists, veteran Ghanaian journalist Elizabeth Ohene reflects on why in Ghana a person's age is not etched in stone.
Ghanaians do not particularly love numbers. We tend to be quite lax, especially with figures that have to do with age.
Someone's date of birth or age is not considered important and very rarely features in any story about that person.
I know that in many parts of the world, once you are born and you acquire a date of birth, it stays with you. It is unchangeable and you die with it.
In Ghana, it is common to see notices in newspapers announcing a change in someone's date of birth. This often happens when a working person's date of retirement is approaching.
People then swear an affidavit to change their profiles from the 59-year-olds they are known to be, to the 55-year-olds that they want to be so they can carry on receiving a salary for a few extra years.
According to the constitution, the retirement age for most public officers is 60.
Seven years younger
Some people have been known to swear affidavits to change their date of birth that would put them in Primary Class One before they were born.
The most dramatic Notice of Change of Date of Birth I have seen was one that reduced an official's age by seven years.
An official of the Electoral Commission (EC) helps a voter to do biometric verification before casting his vote for the presidential election at Bole district in northern Ghana, on December 7, 2016.
Image copyright AFP: Image caption Incorrect birth records could undermine elections
I am writing about this subject because of a recent news item that I thought went way beyond the extraordinary, even for Ghana.
The news report said that about 800 teachers had applied to the Ghana Education Service to have their ages changed.
Some wanted their dates of birth changed to make them younger and a few wanted their dates changed to make them older than what was on their documentation.
The news story was greeted with a lot of outrage and I said to myself: This must mean Ghana is finally joining the rest of the world in paying respect to dates of birth.
"How can people want their dates of birth to be changed?" was the incredulous reaction to the story I heard from many young people.
But then the head of one of the teaching unions came out to make a spirited defence of his members.
The teachers wanted their dates of birth changed only because, according to him, mistakes had been made at the time of their employment by the payroll departments in entering the dates.
Why make a fuss about three years?
This phenomenon has been possible because very few births are recorded.
Once upon a time it was illiterate parents that did not bother to get the births of their children recorded and with time the date got lost in the mists of memory.
A birth certificate is supposed to be provided before a child can be enrolled in school but somehow or other, many people are able to get their children into school without birth certificates.
Elizabeth Ohene:

This total disregard for the sanctity of dates of birth manifests in other ways that sometimes undermines all official records in Ghana.
When in later life you require a birth certificate, you would go before a commissioner of oaths and offer a date that would be said to be based on the best "guessestimate" given you by your parents or family member.
In much later life, when you are approaching the compulsory retirement age of 60 and you desperately want to continue to work a few more years because you can't survive on your pension, you go back to the commissioner of oaths and swear that you have now discovered compelling evidence that the original date of your certificate was wrong.
For example, you were told that you were born in the year the chief of the village was enstooled (inaugurated) and you have discovered he was enstooled in 1968 and not 1965.
There probably does not exist any official record of the date of the enstoolment of this chief anyway, so why make a fuss about a difference of three years?
Ghana school class
Some school children might have voter cards
I have seen school children who cannot be more than 14 years old who have voters registration cards. The law says you have to be 18 to register to vote.
The consequences might follow you through life unless you are prepared to go on paying visits to the commissioner of oaths to acquire new dates of birth.
Police recruitment advertisements have a cut-off date of 25 years.
You are really 21 but have a voters' registration card that says you are 26 because you passed yourself off as 18 when you were 14.
Sometimes it has been football players who try to shave off a number of years from their ages so they can participate in age-restricted competitions.
Nana Akufo-Addo, the new president of Ghana,
Photo: President Nana Akufo-Addo, 73, wants citizens to have ID cards with unchangeable biometric data
These days technology is being deployed to ensure the integrity of such competitions, making it difficult for 20-somethings to participate in under-17 competitions.
A lot of attempts have been made to enforce the registration of births and deaths, and so far all these attempts have failed spectacularly.
There is already in existence a regulation issued by the head of the civil service some years ago which says public officials are not allowed to change their dates of birth during their time in government employment.
In other words, you are stuck with whatever date of birth you enter the service with, and you cannot get younger or older by swearing an affidavit.
It was always going to be difficult to enforce this directive because there are many people here who believe their ages are "confidential" and should not be advertised.
You could ask someone how old they were and get a reply: Is it my official or real age that you want?
One of the firm promises made by the new government is that within its first year in office, a national identification system will be in place.
In other words, all Ghanaians will have identification cards with their unchangeable biometric data and none of us will be able to swear an affidavit to acquire a new date of birth.
Stan Wawrinka of Switzerland plays a forehand in his semifinal match against Roger Federer of Switzerland on day 11 of the 2017 Australian Open at Melbourne Park on January 26, 2017 in Melbourne, Australia.
Switzerland's tennis star Stan Wawrinka has been described as "a mere 31"
We are all holding our breath.
And whilst I await this dramatic change, I have been wondering if there are any advantages in the current situation where a person's age is a changeable and confidential figure?
My mind went to a sentence I read in an online article in a British newspaper earlier this year.
Those who follow tennis would recognise that this was part of a report during the Australian Open:
"A few hours after Serena Williams, 35, joined her 36-year-old sister, Venus, in the women's final by trouncing the 34-year-old Mirjana Lucic-Baroni, Federer, 35, somehow conjured some more retro magic to beat Stan Wawrinka, a mere 31, for the 19th time in 22 matches," the article in The Guardian said.
I fear that faced with the possibility of such prose in our newspapers, many people in Ghana are going to opt to keep dates of birth a changeable and private event.

Create, Edit, or Remove PDF Annotations in UWP
Once PSPDFKit for Windows has loaded annotations from a PDF, these annotations will be made available via the Document API.
The API will return a List of IAnnotations. This interface allows you to determine the AnnotationType and several other properties and methods common to all annotations, such as BoundingBox, Id, PageIndex, and ToJson().
The BoundingBox describes the annotation's location and size on the page. This property is represented by a Rect, with X and Y describing the top-left coordinate of the annotation on the page, and the Width and Height describing the size of the annotation.
PSPDFKit for Windows and PSPDFKit for Web use Instant JSON coordinates. In other words, the origin of the page, "0,0," is at the top left, with the Y axis value increasing as you move down the page. If you need to convert between these coordinates and PDF coordinates — which have their origin, "0,0," at the bottom left, with the Y axis value increasing as you move up the page — you can use the conversion utility methods here.
Using the AnnotationType property, you can cast to a specific annotation type to work with its specific APIs:
if (annotation.AnnotationType == AnnotationType.Ink)
 var ink = annotation as AnnotationType.Ink;
 return ink.IsSignature;
Creating, Updating, and Deleting Annotations
To create an annotation on a page, instantiate the type you want:
var textAnnot = new Text
 Contents = "A new text annotation",
 HorizontalAlign = HorizontalAlign.Right,
 VerticalAlign = VerticalAlign.Center,
 BoundingBox = new Rect(10, 10, 300, 300),
 FontSize = 48,
 Bold = true,
 Italic = true,
 FontColor = Colors.Cyan
Then you can add it to a page like this:
var createdTextAnnotation = await pdfView.Document.CreateAnnotationAsync(textAnnot);
After it's added to a page, the new annotations will have a unique Id.
If you wish to update an existing annotation, this can be done like so:
createdTextAnnotation.VerticalAlign = VerticalAlign.Top;
createdTextAnnotation.Opacity = 0.5f;
await pdfView.Document.UpdateAnnotationAsync(createdTextAnnotation);
To delete an annotation, you only need its Id:
await pdfView.Document.DeleteAnnotationAsync(createdTextAnnotation.Id);

text: The design of automated negotiators has been the focus of abundant research in recent years. However, due to difficulties involved in creating generalized agents that can negotiate in several domains and against human counterparts, many automated negotiators are domain specific and their behavior cannot be generalized for other domains. Some of these difficulties arise from the differences inherent within the domains, the need to understand and learn negotiators' diverse preferences concerning issues of the domain and the different strategies negotiators can undertake. In this paper we present a system that enables alleviation of the difficulties in the design process of general automated negotiators termed Genius, a General Environment for Negotiation with Intelligent multi-purpose Usage Simulation. With the constant introduction of new domains, e-commerce and other applications, which require automated negotiations, generic automated negotiators encompass many benefits and advantages over agents that are designed for a specific domain. Based on experiments conducted with automated agents designed by human subjects using Genius we provide both quantitative and qualitative results to illustrate its efficacy. Our results show the advantages and underlying benefits of using Genius for designing general automated negotiators.

Quick Answer: How Does Wax Recording Work?
Does black vinyl sound better?
Only white should sound worse.
The white substance used to due the record can cause random pops (rumor has it that it is a kind of chalk).
Other vinyl – colored or clear can be dead-quiet.
so a colored vinyl record with no black in it may actually sound better right out of the wrapper than a black one..
What is a wax record?
The wax record simply put is a hollow cylinder made from wax that, when put into a phonograph or graphophone machine it allows you to record sound and reproduce that same sound.
Why is vinyl called wax?
This was electroplated to make the metal parts to stamp finished records. Hence, for almost the first 50 years of recorded sound, including cylinders, wax was the media that took the original sound waves. Therefore the term "wax" came into popular use as slang for a record.
Is Vinyl A plastic?
Vinyl (polyvinyl chloride or PVC), is the world's most versatile plastic, used to make everything from food wrap to auto body parts. Vinyl is composed of two simple building blocks: chlorine, based on common salt, and ethylene, from crude oil.
Is a record player worth it?
It's mainly worth it if you're going to listen to stuff on vinyl. There's no point in making the investment if it's going to sit and collect dust. If you feel drawn to vinyl, then absolutely. It's mainly worth it if you're going to listen to stuff on vinyl.
When were wax cylinders used?
The Edison Phonograph Company was formed on October 8, 1887, to market Edison's machine. He introduced the Improved Phonograph by May of 1888, shortly followed by the Perfected Phonograph. The first wax cylinders Edison used were white and made of ceresin, beeswax, and stearic wax.
What were records originally made of?
Why is vinyl used for records?
Why is it that vinyl records are generally black? PVC (polyvinyl chloride), the material that vinyl records are made of, is clear in its natural form, allowing records to be manufactured in just about any color imaginable.
Does vinyl actually sound better?
Vinyl is far more high-quality. No audio data is lost when pressing a record. It sounds just as great as the producer or band intended. There's another, far superior reason why vinyl is better than lossy digital formats.
Is my record a 33 or 45?
12″ records that are albums (>20 minutes per side) are 33, 12″ records that are singles may be 33 if they are from the US or 45 if they are from Europe. 10″ records are usually 33, but there may be 45 as well.
How long does a gramophone needle last?
Most manufacturers recommend changing your stylus at around 1000 hours of record playing time. So if you're using your turntable for an hour or so per day on average, ideally you should be changing the stylus every couple of years.
How do gramophones work?
Like other record players, gramophones read the sound with a small needle which fits into the groove in the record. That needle is attached to a diaphragm, which in turn is attached to a horn. … These vibrations are transmitted to the diaphragm, which itself vibrates, creating sound.
Are 78s worth anything?
"The early blues material from the '20s and '30s is the hottest material of all," Mr. Tefteller said in a phone interview. He said that on average a rare jazz 78 might sell for $1,500 to $5,000, whereas sales for a comparable blues record would start at $5,000.
What was the first song ever recorded on the phonograph?
Au Clair de la Lune.On April 9, 1860, Scott recorded a snippet of the French folk song "Au Clair de la Lune."
Who invented wax cylinders?
Thomas EdisonPhonograph cylinder/InventorsEdison had introduced wax cylinders that played for nominally 4 minutes (instead of the usual 2) in 1909 under the Amberol brand. They were made from a harder (and more easily breakable) form of wax to withstand the smaller stylus used to play them.

Why is tinfoil a poor medium for recorded sound?
The recordings could be played only a few times before the indentations made by the sound on the tinfoil were so flattened down as to be unplayable. … It was changes in the physical medium itself that would ultimately exert the most long-lasting effects on the evolution of American sound recording history.
How does a vinyl record work?
Vinyl record players are electromagnetic devices that change sound vibrations into electrical signals. When a record spins, it creates sound vibrations that get converted into electrical signals. … Electric amps vibrate and feed the resulting sound into speakers, which amplify it and make it louder.

What's the difference between a turntable and a record player?
What Is A Turntable? In its basest form, a turntable is simply a major component of a record player. … But turntable also refers to a standalone unit you can purchase. In this sense of the word, a turntable is similar to a record player, except it does not come with built-in speakers or an amplifier.
What replaced records?
In an attempt to head off the disc advantage, Edison introduced the Amberol cylinder in 1909, with a maximum playing time of 4 1⁄2 minutes (at 160 rpm), which in turn were superseded by Blue Amberol Records, which had a playing surface made of celluloid, a plastic, which was far less fragile.

You should consider passing the value via the model:
_USER_.CheckBoxFor(model => model.abcd)
If you need to set it to be 'false' then you can do this by setting the abcd property to false in the Controller before returning the View.

Checkboxes don't have different checked/unchecked values, they only have a checked value. If you understand why razor outputs the hidden field then you understand this.
Imagine for a second that it did have value='false'. What would happen when you checked the checkbox? Would you expect the value to change? (hint: you shouldn't). You'd have a checked checkbox with value='false'. What does that even mean? Then, upon posting, you would post false as your value, and that would be nonsense.
So. Checkbox value attributes don't change. If you need to write code that uses the value, don't look for its value, look for whether or not it's checked.

So if i need the checkbox to be checked and unchecked based on the true or false that we pass eg _USER_.CheckBox("abcd",false) what should i do? Since i couldnt get what i wanted from your answer. – Desmond Nov 16 '12 at 9:01
_USER_ A checkbox inputs "checked" state is a separate property from its value. Notice that if you check and un-check a textbox the value property does not change, however the browser sees whether the checkbox is checked or not and if it's checked it posts the input name/value, if it's not checked it does not post anything at all. Hence why there's automatically a 2nd hidden input field with value set to false created, so if user checks the checkbox the server will receive two key/value pairs for both inputs, true and false and it will accept true in this case, if one just false. – LaserBeak Nov 17 '12 at 6:41
