Russian training focus in 2017 - Amphibious operations
For the Russian armed forces 2014 was the year of snap drills and the Ukraine war. 2015 brought in the Syrian expeditionary force and larger readiness exercises. 2016 saw the resurgence of army level operations and strategic relocation training. In 2017 the most notable change is the focus on the amphibious operations and river crossings.
Russian Naval infantry BTR-82A APC:s and a Zubr class landing craft
The Russian naval infantry was established by Peter the great in 1705. The naval infantry has been subordinated to the Russian Navy and it has never been treated as an individual service like the United States Marine Corps. While the quality of the Russian Naval infantry has varied wildly along the centuries it established an elite status during the World War 2. The importance of the Soviet Naval Infantry grew steadily and some elements of it, such as the parachute battalions, were considered equal to the VDV airborne troops.
After the Cold War the Russian military turned to face more unconventional threats and major naval landing operations were not given a high priority. Most of the modernization budget of the Russian Armed Forces went to the army and the VDV. The importance of the Naval infantry began to grow as the President Putin restructured the Russian armed forces for offensive operations.
Crimea and Syria
The most high profile operation of the Russian naval infantry in the recent times was the invasion of Crimea, where the 810. Naval Infantry brigade was involved in disarming the Ukrainian marines and naval forces together with GRU speznaz and VDV airborne units.
The naval infantry from the Black Sea Fleet and the Northern Fleet have also been active in Syria. They have been providing security for the Russian naval base in Tartus for a long time. As the Russian involvement in the Syrian civil war has deepened, the naval infantry has also expanded its force in the theater. The motorized naval infantry units with their BTR-82 APC:s have supported the Syrian Arab Army in many operations. Syria, while not exactly a naval operation, has been an important test for the combat and expeditionary capabilities of the Russian naval infantry.
Increased drills in 2016
The focus of the Russian naval infantry and naval spetznaz forces have been in unconventional warfare, base security and special operations against enemy shore based facilities. In 2016 the Russian naval infantry conducted several amphibious landing drills into unprepared shores with the support of the naval gunfire, army aviation helicopters and air-force tactical bombers.
These drills happened in all of the four major fleets and they ranged from a battalion sized landings to the small islands in the Gulf of Finland to a brigade level operations in the occupied Crimea.
In 2017 these drills evolved into more complicated ones. The drills involved more units and support assets. All of the fleets also tested and exercised loading and unloading of the VDV airborne units in amphibious landing conditions. The unique equipment of the VDV such as the BMD-4 infantry fighting vehicles and the Sprut-SD tank destroyers can provide important capabilities to a landing force. More importantly the VDV units are by design expeditionary and can operate independently inside enemy territory.

The integration of the VDV units into the naval infantry forces significantly bolsters the number of elite troops that Russia can use to land into the enemy shores. The VDV units are also easily air-transportable, so they have an unsurpassed strategic mobility. These landing operations would also provide an use for the newly formed VDV tank battalions, that can't be airdropped, unlike the other VDV formations.
During the fall training season, the Russian northern fleet took on new challenges. It conducted a long distance training operation that spanned nearly the entire northern coastline of Russia. The Northern Fleet landing force carried a mix of marines, paratroopers and arctic warfare specialists form the 200th Independent Motor Rifle Brigade based at Alakurtti, to a several landings in the high arctic. The longest assault happened over 2000 kilometers away from the jump off point. These locations and transit distances could mimic assaults against Iceland or Svalbard.
In addition to the published amphibious landing exercises, the Russian Northern Fleet has also been actively training small units into arctic operations under the disguise of scientific expeditions and environmental cleanup projects. Some of these expeditions have even transited through the demilitarized Svalbard islands.
New boats
While the introduction of the airborne forces into the naval infantry operations indicates a desire to conduct larger scale amphibious operations that would be possible with only the dedicated units, the procurement of naval landing equipment shows that there is still significant drive to increase the special operations capability of the Russian navy.
Russia has recently introduced four separate classes of combat boats, that provide it's naval infantry and spetsnaz forces with increased mobility and protection in coastal waters and riverine operations.

Three of the boat classes resemble the Swedish Combat Boat 90 at least visually. Kalashnikov BK-16 and BK-18 can transport half a platoon of infantry to a range of 400 km Armament of these boats are a mix of crewed machine guns and grenade launchers and a remote weapon station mounting a 12,7 mm machine gun. The boats also carry a Kalashnikov designed UAV:s to provide the landing unit with better situational awareness. BK-series boats have two 780 hp engines, that can push the boat to speeds up to 43 knots.
The Project 03160 Raptor, while externally similar to the BK-series, is supposed to be a more advanced design than the Kalashnikov boats. It's armed with 14,5 mm RWS and supposed superior sensors and better sea going abilities. It's also supposedly faster and easier to operate. The Raptor has 2000 hp engines and a top speed of 50 knots.

The fourth boat design is a more streamlined project 02800. The first time one of these sleek boats participated in a real world training exercise was on 19th of October 2017, when it supported an amphibious landing drill of the Baltic Fleet in Kaliningrad. Technical details of the new boat are still scarce. The layout of the Project 02800 resembles the Finnish Jurmo-class assault boats, but my subjective opinion is that the Russian counterpart looks way more sexy.
In addition to the combat boats, the Russian navy has procured five Project 21820 aka. Dyugon-class landing crafts. These crafts can land an motorized infantry company or a main battle tank platoon into an unprepared shore. Three of these crafts are based in the Baltic fleet, one in the Pacific Fleet and one in the Caspian sea.

In order to support larger amphibious operations in the high arctic, where harbors and shore facilities are scarce, Russia has developed their version of a Mulberry Harbor. Mobile harbor facilities that were established on the coast of Normandy immediately after the D-Day landings, were crucial for the allied war effort.
None of the recent acquisitions can replace the capabilities that the Russian Navy lost, when the French government refused to sell Russia the Mistral-class assault ships. If Russia had received the Mistrals it could pose a threat even to a defended shoreline.
Possible targets and capabilities
The Russian navy has limited number of amphibious assault ships and larger landing crafts that are capable of supporting mechanized naval infantry units. These assets are divided between the four major fleets. This limits the Russian naval infantry more than the number of available amphibious trained infantry units.
Russia can land an brigade from its Northern, Baltic and Black Sea fleets. With the support of the new high speed boats this can be improved only slightly. The greatest advantage they bring is the ability to land special forces in advance of the main landing party. Naturally they also increase the ability to conduct special operations missions along the enemy shorelines and into hostile and neutral installations, such as the Ukrainian gas rigs, that Russia occupied in the Black Sea.
Considering the obvious lack of heavy naval assets and carrier borne aviation, the list of targets Russia can use it's expanding naval landing capabilities for is relatively short. In the high arctic there are only four probable targets Svalbard, that has a Russian settlement of Barentsburg as a staging area, Iceland and Jan Mayen. The fourth is a landing along the Norwegian coast, but that would mean a full blown ground war against a NATO member.

In the Baltic Sea region the list of suitable targets for amphibious landings is likewise very short, Gotland and Åland that can provide a game changing advantage by effectively cutting off NATO access to the Baltic states. As with Norway, Russia could use naval landings to support a strategic strike against Finland or the Baltic states. Especially Finland would be a suitable target for such strike as the Finnish reserve based defense takes some time to respond to a brigade level or larger operations against it's shoreline. Although situation in Finland in improving.
In the Black Sea there is a broader spectrum of possible naval operations that Russia could conduct against Ukraine or Georgia. The concentration of combat boats in the Black Sea Fleet shows that Russia is expecting to use SOF assets rather than brute force landings. The landing and transport ships of the Black Sea Fleet are also crucial at supplying the Russian expeditionary force in Syria.
While the expansion of amphibious trained troops and the introduction of the new combat boats are not massive game changers, they clearly show that Russian armed forces


The Real Reason There's An Absorbent Pad In Meat Packages
When you buy meat, you've likely noticed the pad that comes in the packaging, and you've thrown it away without giving it any thought other than trying not to drip meat juice all over yourself, the floor, or the counter. However, the pad actually does serve an important purpose.
The reason it's there is not surprising — it's to soak up liquids from the meat or poultry to prevent them from pooling in the package. This serves multiple purposes. For one, it makes the cooking process less messy, which is important for hygiene in the home (via MyRecipes). It is also a food safety measure. The liquids from meat, unappetizingly referred to as "purge," can contain bacteria, and by absorbing the liquids, it prevents as much live bacteria as possible from leaking, as well as preserving the meat or poultry because the liquid would otherwise cause more bacteria to grow. This would increase the risk of foodborne illnesses (via My Fearless Kitchen).
What is the pad made of?
The absorbent pads are made from specific forms of paper with a plastic liner, according to the U.S. Department of Agriculture (USDA), the agency in charge of the production, packaging, and safety standards of food made in the United States.
The packaging is regulated and overseen by the Food and Drug Administration (FDA) to ensure that it doesn't contain harmful chemicals. Every piece of material that goes into meat or poultry packaging has to be individually petitioned and approved by the agency before it can be put into the pack with meat (via USDA).
The pads are made from silica gel, purified sand, or from cellulose, which is a purified plant fiber. The pads are then coated in a non-toxic, perforated plastic wrap, which allows the liquid to seep into the pad and remain there, sort of like the wicking fabric in workout clothing holds the sweat off your body so wet clothes aren't against your skin.
Is this absorbent pad safe?
As a result of the regulatory process, these pads that can hold up to 40 grams of liquid are generally safe. While eating the absorbent pad is obviously not recommended, if you find that it sticks to your meat and you accidentally cook it, so long as the pad isn't melted, torn, or broken open after the meat has been cooked, the meat is still safe to eat. Any bacteria that may have lingered on the pad would have been killed during the cooking process. Just remove the remaining bits and enjoy your meal.
Even if you do accidentally ingest a piece of the pad, it isn't digestible so it should move straight through your digestive tract without breaking down so you will likely be fine though best to try to avoid it in the first place.

Shipwrecks discovered throughout Southeast Asia and the precious cargoes they contain represent invaluable information for the study of international trade networks. However, these treasure troves of Thai, Vietnamese and Chinese ceramics, have up until this point, been unsystematic ally studied and rarely published. This book addresses this issue with the author tracing the development and fluctuations of the international ceramic trade between China and Southeast Asia focusing specifically on the 14th-15th centuries, a period known in ceramic scholarship as the Ming Gap. The term Ming Gap arose to describe the ban placed on the export of Chinese ceramics by the Ming Dynasty. The author illustrates how as a result, Southeast Asian ceramics began to fill this void and for over a century became the dominant ceramic trade ware throughout the region. Analyzing over 120 shipwrecks, the author for the first time proposes a chronology of ceramic production placing Thai ceramics into five chronological periods and discussing issues such as the relationship between Sukhothai and Sawankhalok kilns, the discovery of exported Burmese celadon wares and the location of Vietnamese production sites for ceramic exports.

Nonlinearity in Broadband Wireless Communication Systems
Licentiatavhandling, 2003
In the implementation of a digital communication system, there often exist imperfections that are not considered in the primary design. One such imperfection is the nonlinearity of the front-end devices. In most cases the physics of the nonlinearity is not completely known, and therefore the analysis of the system is very difficult, if not impossible. In this case models based on the observations from the device behavior has to be built and used in the study of the system. This thesis focuses on modeling and analysis of a system with nonlinearity. The topics covered here are modeling the nonlinearities, the impact of nonlinearity on a digital communication link, compensation of the nonlinearity effects, and measures to evaluate the susceptibility of signals to nonlinearity. In the modeling part, a model for a bandpass nonlinearity which is based on measurements on several harmonics of the output is presented. Unlike linear systems, in nonlinear systems a baseband equivalent does not contain all the information about the bandpass system. In this case the original bandpass model has to be used in some analysis. The model is then used to evaluate the performance of a broadband wireless communication system in the presence of nonlinearity. Two major classes of modulation for broadband wireless transmission are studied and the effect of nonlinearity on them is addressed. We also present and compare several methods of compensating the nonlinearity of the RF front-end of a wireless system. The methods include baseband and RF compensation methods. The design procedure for each one is discussed and the performance of the compensated system is evaluated. Finally we study signal measures related to nonlinearities, such as PAPR (Peak-to-Average-Power-Ratio), with respect to their ability to correctly predict the impact of a nonlinearity on an OFDM (Orthogonal Frequency Division Multiplexing) system. We also propose new measures for signal distortion in nonlinear systems.
baseband predistortion
single carrier modulation
orthogonal frequency division multiplexing (OFDM)
bandpass nonlinearity
multicarrier modulation
nonlinearity distortion
high power amplifier
RF predistortion
peak to average power ratio (PAPR)
baseband nonlinearity

After reading this chapter, you should understand the following:
- The liability of an agent who signs commercial paper
- What contract liability is imposed when a person signs commercial paper
- What warranty liability is imposed upon a transferor
- What happens if there is payment or acceptance by mistake
- How parties are discharged from liability on commercial paper
In Chapter 22 "Nature and Form of Commercial Paper", Chapter 23 "Negotiation of Commercial Paper", and Chapter 24 "Holder in Due Course and Defenses", we focused on the methods and consequences of negotiating commercial paper when all the proper steps are followed. For example, a maker gives a negotiable note to a payee, who properly negotiates the paper to a third-party holder in due course. As a result, this third party is entitled to collect from the maker, unless the latter has a real defense.
In this chapter, we begin by examining a question especially important to management: personal liability for signing company notes and checks. Then we look at the two general types of liability—contract and warranty—introduced in Chapter 23 "Negotiation of Commercial Paper". We conclude the chapter by reviewing the ways in which parties are discharged from liability.


text: Silt Fences are temporary silt control devices that are designed to prevent the release of silt from a construction site. Silt fences prevent silt contamination of sensitive areas such as neighboring properties, streams, and sewer catch basins. A properly installed and maintained silt fence will collect silts before they can cause contamination requiring expensive clean up. Silt fences create a puddle behind the fence that acts as a "stilling basin" allowing silts to settle. Silt Fences are most often used on construction sites where the soil has been stripped of natural vegetation. The bare soil is easily eroded and can lead to the loss of silt in the event of a run-off event. The silt fence helps to prevent the movement of silt from the bare soil area to an adjacent area.

NYC Employers: Watch For Proposed NYC Legislation Limiting the Use of AI in Hiring
New York City is considering proposed legislation that would regulate the use of artificial intelligence in hiring.
If passed, the new law would (effective January 1, 2022) require that, in order to sell an "automated decision tool" in New York City, the tool's developer must:
 1. Be able to show that the tool was the subject of a "bias audit" conducted in the past year;
 2. Offer, at no additional cost, an annual bias audit and provide the results of the audit to the purchaser; and
 3. Include a notice (aimed at the purchaser) stating that the tool is subject to the provisions of this law.
One potential issue here is that "automated decision tool" is defined in a way that may sweep in a broad range of selection tools:
"Any system whose function is governed by statistical theory, or systems whose parameters are defined by such systems, including inferential methodologies, linear regression, neural networks, decision trees, random forests, and other learning algorithms, which automatically filters candidates or prospective candidates for hire or for any term, condition or privilege of employment in a way that establishes a preferred candidate or candidates."
Notice to Candidates
In addition to imposing requirements on a tool's developer, any employer who uses such a tool must provide a notice to candidates (within 30 days of them being screened) of:
 1. The fact that an automated decision tool that is required by the law to be audited for bias was used in connection with their candidacy; and
 2. The job qualifications or characteristics that such tool was used to assess in the candidate.
The law doesn't address the degree of specificity with which "qualifications or characteristics" must be described in the notice. We believe that general descriptions of broad competencies (e.g., "customer orientation" or "problem-solving") should suffice.
Bias Audit
The required "bias audit" is defined as "an impartial evaluation," of the tool "to assess its predicted compliance with the provisions of section 8-107" of the New York City Code. Section 8-107 is the anti-discrimination section of the City Code. It includes, among other provisions, a prohibition against employment practices that have disparate impact. In general, this provision tracks the definition of disparate impact from federal law, with one very significant difference. While federal law focuses on disparate impact on the basis of race or gender (and expressly requires the collection of race and gender data to assess adverse impact), the City Code encompasses disparate impact based on any protected characteristic, meaning "age, race, creed, color, national origin, gender, disability, marital status, partnership status, caregiver status, sexual and reproductive health decisions, sexual orientation, uniformed service or alienage or citizenship status."
That last aspect could create a significant compliance hurdle for employers, since they generally do not (and cannot, without running afoul of other laws) collect information about applicants' protected characteristics other than race and gender, making it difficult to see how a tool developer could test whether or not its tool is likely to have disparate impact on other groups.
While the law continues to work its way through committee, businesses that are based in or hire employees for positions in New York City should review their pre-employment selection tools and confer with their vendors to determine if they utilize learning algorithms and, therefore, could be subject to the new law.

You already know that a strong headline gets people to start reading
your (advertising or marketing) copy. You also know that the purpose of
every paragraph is to get people to continue to read the rest of the
copy. But what happens when people get to the end of your copy?
Each of Aesop's Fables end with a brief moral ("One bad turn deserves another" or "Appearances are deceptive") that summarizes the point of the story. Does your copy end with a moral-like statement? I think of this phrase as a "toeline" (the opposite of a headline). While a headline focuses on the benefit to the reader, the toeline focuses on your offering with a reminder about the benefit.
For example, if you're selling raw, organic cat food (called Purely Cat Food), your headline might read: "Keep Your Cat Healthier Naturally". Your copy would describe why most commercially available cat food is bad for cats, and by feeding your cats this food they'll live longer and be sick less. Most people end the copy with "Now available at your local store".
Instead, create a toeline that echoes the headline. For example, "Purely Cat Food Ensures Your Pet's Health". Notice it starts with the offering, then mentions the benefit.

Why does your school need to be involved in the IAP project?
Schools are having to deal with an increasing number of children who struggle to cope with mainstream education due to learning, wellbeing and safeguarding challenges. This can lead to children being excluded from mainstream classrooms, or excluding themselves through non-attendance.
Internal Alternative Provision (IAP) can be an essential part of the system to support these children in school. IAP can increase attendance, limit the use of internal exclusion and reduce suspensions.
This project is suitable for both primary and secondary settings.
- To reflect on the school's current context, systems and practice to develop a clear intent for Internal Alternative Provision.
- To use a framework to create a plan for a trauma-informed, relational, asset-focussed Internal Alternative Provision.
- To know what structures, systems and practices are required for effective referral, intervention and reintegration from Internal Alternative Provision.
The project will include four interactive and practical online sessions led by Will across the academic year. Following each session, participants will be set a short practice-based assignment (not mandatory but helpful!) relating to supporting children at risk of exclusion and/or persistent absence.
This session will focus on the desired intent of your IAP and the context of your school. It will include;
- Key principles for inclusive, relational IAP and introducing the framework
- Different models of IAP, their advantages and disadvantages
- Measuring success; data and impact measurement
This session will focus on referral to IAP and the induction of children (and their families).
- Being authentically collaborative with families – systemic and asset-based approaches
- Curiosity to understand underlying causes of challenging behaviour and/or persistent absence.
- Developing effective student profiles and support plans.
This session will focus on the intervention phase (what happens) of IAP.
- Reflection on what works and what doesn't in relation to our intent.
- SEMH needs, trauma-informed and relational practices.
- Curriculum design and interventions to support children's assets and needs.
This session will consider the reintegration from IAP to mainstream lessons as well as focus on the next steps for developing effective IAP in your school.
- Key challenges for sustainable reintegration.
- Components of an effective transition / reintegration plan.
- Reflection on intent and how this can be measured.
- Action planning next steps.
Internal Alternative Provision Project
Will is an experienced senior leader and Special Educational Needs Co-ordinator. He has spent more than 10 years working with children with social, emotional and mental health (SEMH) needs in Alternative Provision, Pupil Referral Units, primary, secondary and special schools. Too many times he has seen children excluded from school who needn't be. His experience as a senior leader in a range of settings as well as a specialist foster carer has helped him realise collaboration between schools, families and the wider network is the most effective way to help children thrive.

An SQL statement can be preceded by the keyword "EXPLAIN" or by the phrase "EXPLAIN QUERY PLAN". Either modification causes the SQL statement to behave as a query and to return information about how the SQL statement would have operated if the EXPLAIN keyword or phrase had been omitted.
The output from EXPLAIN and EXPLAIN QUERY PLAN is intended for interactive analysis and troubleshooting only. The details of the output format are subject to change from one release of SQLite to the next. Applications should not use EXPLAIN or EXPLAIN QUERY PLAN since their exact behavior is variable and only partially documented.
When the EXPLAIN keyword appears by itself it causes the statement to behave as a query that returns the sequence of virtual machine instructions it would have used to execute the command had the EXPLAIN keyword not been present. When the EXPLAIN QUERY PLAN phrase appears, the statement returns high-level information regarding the query plan that would have been used.
The EXPLAIN QUERY PLAN command is described in more detail here.
The EXPLAIN and EXPLAIN QUERY PLAN prefixes affect the behavior of running a prepared statement using sqlite3_step(). The process of generating a new prepared statement using sqlite3_prepare() or similar is (mostly) unaffected by EXPLAIN. (The exception to the previous sentence is that some special opcodes used by EXPLAIN QUERY PLAN are omitted when building an EXPLAIN QUERY PLAN prepared statement, as a performance optimization.)
This means that actions that occur during sqlite3_prepare() are unaffected by EXPLAIN.
Some PRAGMA statements do their work during sqlite3_prepare() rather than during sqlite3_step(). Those PRAGMA statements are unaffected by EXPLAIN. They operate the same with or without the EXPLAIN prefix. The set of PRAGMA statements that are unaffected by EXPLAIN can vary from one release to the next. Some PRAGMA statements operate during sqlite3_prepare() depending on their arguments. For consistent results, avoid using EXPLAIN on PRAGMA statements.
The authorizer callback is invoked regardless of the presence of EXPLAIN or EXPLAIN QUERY PLAN.

What properties of urethane make it uniquely applicable to its products?
1 Answer | Add Yours
Based on its unique characteristics, Urethane products have been designed to cater to various needs. For example, Urethane excels in mechanical strength – hence used in the making of high tensile strength adhesives. It can endure extreme conditions such as exposure to severe temperatures, salt water, and UV light - used in the making of marine industrial products, making of skateboards, buoys, mining and water treatment applications. It is resistant to cigarette fire – thus used in making bedding materials. It is water repellent – used in a wide range of coating and waterproofing membranes.

Boxing and unboxing are to be avoided, but that's not the same as saying you should avoid using the Systems.Collections classes for values. There are more ways to box values, and sometimes the code savings is worth the performance costs.
Conventional Wisdom Explained: 'as' and 'is' vs. casting
I'm not going to discuss performance here, because that's not the reason to pick one or the other. The as and is operators do not examine user defined conversion operators. Casts can make use of both explicit and implicit conversion operators. The exact behavior of user defined conversions and casts gets complicated, and relies on the compile-time type of the arguments. I discussed all the details on pages 18 – 24 of Effective C# (Item 3).
The next important question is whether or not it's an error condition if the conversion fails. If it's an expected behavior to receive inputs that are not the expected type, the as and is operators provide simpler checks than introducing exceptions. However, if you're going to write this:
if (! o is ExpectedType )
 throw new ArgumentTypeException( "You didn't use the right type" );
Please just use the cast instead. It's clearer. On a related note, consider the difference between double.Parse() and double.TryParse(). One assumes success and throws exceptions when it fails. The other returns error codes to indicate a problem.
Conventional Wisdom Debunked: for loops are faster than foreach
I'm not going to say that foreach is faster. However, I am going to say I'm happy to work in an environment where the compiler writers work hard to optimize the language constructs that are the most versatile. The C# 1.1 compiler added optimizations to the code generated by foreach loops and arrays. In version 1.0, the for loops were much faster. That's no longer true. (Remember that earlier recommendation to profile your code?)
The best practice here is to write the clearest code you can, and expect the compiler to optimize properly. If necessary, profile and improve.
Conventional Wisdom Debunked: NGen will improve performance
Maybe. Then again, maybe not.
This is a dangerous recommendation. Yes, it's true that nGen will lower the startup time for some assemblies. It's also true that you will lose some of the advantages of JIT compilation. There are a number of optimizations that the JIT compiler can perform only at runtime. This whitepaper gives a good overview of the advantages of leaving the JIT step to runtime.
This is a performance only recommendation that I would never blindly follow without profiling both versions, both startup times and operating times. In addition, you should profile combinations of NGen'ed and regular assemblies.
As I said in my opening the purpose of an Effective book is to provide the most useful pieces of advice to the most developers. That advice must be justified with the technical information to help readers decide when advice applies, and under what scenarios it can be safely ignored. I've given you a taste of the justification I gave readers in Effective C#, and how that sometimes conflicts with the recommendations often repeated among C# developers. Addison-Wesley, The Code Project and I are working to excerpt some of the Effective C# items here for Code Project readers.

I agree with you, but I would not say the sanity check is obscure. That behavior is based on the very definition of the foreach pattern. Not complying with it would break the contract and would be a bug.
There is a lot of trick that the C# compiler is doing for you, but each compiler is a different beast Smile | :)

In archaeology a postpipe (or post pipe) is the term given to the remains of an upright timber placed in a posthole. Given the right conditions, timbers may survive over long periods of time and a recovered postpipe can simply be of solid wood. Under less preservative conditions however, only a dark circular stain of organic material may be left in the fill of the posthole observable in plan and section. This differs in consistency from the less organic backfill of the posthole and can be identified simply through this change in make-up. The size and depth and of the postpipe can provide information as to any reuse of the posthole especially if several different postpipes can be identified. They can also indicate the species of wood used and help suggest the nature of the structure that the timber once supported.

Exposure to urinary catheters is considered the most important risk factor for healthcare-associated urinary tract infection (UTI) and is associated with significant morbidity and substantial extra-costs. In this study, we assessed the impact of urinary catheterisation (UC) on symptomatic healthcare-associated UTI among hospitalized patients.
A nationwide period prevalence survey of healthcare-associated infections was conducted during 1 May to 30 June 2004 in 49 Swiss hospitals and included 8169 adult patients (4313 female; 52.8%) hospitalised in medical, surgical, intermediate, and intensive care wards. Additional data were collected on exposure to UC to investigate factors associated with UTI among hospitalised adult patients exposed and non-exposed to UC.
1917 (23.5%) patients were exposed to UC within the week prior to survey day; 126 (126/8169; 1.5%) developed UTI. Exposure to UC preceded UTI only in 73 cases (58%). By multivariate logistic regression analysis, UTI was independently associated with exposure to UC (odds ratio [OR], 3.9 [95% CI, 2.6-5.9]), female gender (OR, 2.1 [95% CI, 1.4-3.1]), an American Society of Anesthesiologists' score > 2 points (OR, 3.2 [95% CI, 1.1-9.4], and prolonged hospital stay >20 days (OR, 1.9 [95% CI, 1.4-3.2]. Further analysis showed that the only significant factor for UTI with exposure to UC use was prolonged hospital stay >40 days (OR, 2.9 [95% CI, 1.3-6.1], while female gender only showed a tendency (OR, 1.6 [95% CI, 1.0-2.7]. In the absence of exposure to UC, the only significant risk factor for UTI was female gender (OR, 3.3 [95% CI, 1.7-6.5]).
Exposure to UC was the most important risk factor for symptomatic healthcare-associated UTI, but only concerned about half of all patients with UTI. Further investigation is warranted to improve overall infection control strategies for UTI.

(Phys.org)—Finding the similarities between volleyball and snooker may seem quite tricky. However, a group of physicists have found that the spread of scores, otherwise known as distribution, across their ranking systems are almost identical.
They've also shown that this is the same for almost all sports, whether their ranking systems are based on points or the earnings of each individual or team.
Publishing their study today in the New Journal of Physics, the researchers came to this conclusion by statistically analysing the ranking systems across 12 different sports: tennis, golf, table tennis, volleyball, football, snooker, badminton, basketball, baseball, hockey, handball and fencing.
Rankings are a direct measure of a player or a team's performance and come in different forms. Some sports are ranked using a points system, while others are ranked using earnings. By statistically analysing the rankings and plotting them onto graphs, the researchers found that the distributions for each sport were almost identical.
The reason why the ranking systems have a common distribution is unknown and is the latest example of a phenomenon that abides by the mysterious 'power laws' – a term used to describe phenomena where large events are rare and small events are common.
In the past, research has shown that the frequency of words in different texts, the size of cities and people's income all abide by the same power law.
Co-author of the study, Dr Wei Li, said: "Let's take human wealth. The chance of being a billionaire is small, but not zero as we see thousands of them in the world. At the same time, the chance of being poor is very high. We call this distribution a power law and, for some unknown reason, witness exactly the same distribution in other everyday phenomena.
"The sports ranking systems we analysed all follow similar power-laws."
The researchers, from Hua-Zhong Normal University, ISMANS (LUNAM Université), Université de Maine and Max-Planck Institute for Mathematics in the Sciences, also found that the sport rankings agree with a maxim known as the Pareto principle.
Also known as the 80-20 rule, this states that, for many events, roughly 80 per cent of the effects come from 20 per cent of the causes. Vilfredo Pareto noticed this in 1906 when he found that 80 per cent of Italy's land was owned by 20 per cent of the population. The rule also applied to a variety of other countries he analysed.
In all of the sports analysed, 20 per cent of the players possessed 80 per cent of the total scores of the whole system.
"We all want to be the best or at least one of the best in some aspects. A businessman wants to be Bill Gates; a model wants to be Cindy Crawford; a tennis player wants to be Roger Federer. The idea of ranking is ubiquitous throughout our human society and we have found that for a number of sports, there is a similar law which dictates how these rankings pan out," continued Dr Li.

Estimating Irrigation Water Quantity and Qualityby Otto J. Helweg, (M.ASCE), Assoc. Prof.; Dept. of Civ. Engrg., Univ. of California, Davis, Calif.,
Desi Alvarez, (A.M.ASCE), Engr.; Tetra Tech, Pasadena, Calif.,
Serial Information: Journal of the Irrigation and Drainage Division, 1980, Vol. 106, Issue 3, Pg. 175-188
Document Type: Journal Paper
Abstract: The value of water quantity and quality is shown by its demand curve (surface). But because the market for water is imperfect, the demand surface must be derived by other means. This paper shows a theoretical process for determining the derived demand surface for both water quantity and quality, using data for citrus crops in California. The results show that for the relevant price range, the demand for water quantity is relatively inelastic, indicating that pricing is not an attractive mechanism for controlling water distribution; however, the demand for water quality is relatively elastic which makes pricing a possible means for managing water quality. The results also support the claim that the value of water is considerably more than most irrigators pay for it.

Xbase - Clever solution to laser engraving fumes.
The Xbase extraction and filtration system.The Xbase extraction and filtration system with a laser engraving machine attached on top.
The need to extract hazardous fumes from engraving lasers to protect the health of the operator and to prevent damage to the laser itself is obvious. But what is the best way to do it?
Engraving lasers burn away layers of material such as glass, wood, rubber and metal in order to make an engraving. This process releases various gases, vapours and particles that can affect the quality of an engraving or damage the laser. These fumes can also cause long-term medical conditions if inhaled by the operator.
Health and safety regulations demand that operators of equipment that produce hazardous fumes are protected. One answer to this particular problem is a fume extraction system that connects to the engraving laser.
In the past, laser owners may have connected a fume extraction system that takes hazardous fumes from the laser and discharges them into the atmosphere outside. This has several drawbacks.
To install an external discharge system can require the hiring of specialist companies to drill holes through walls or ceilings, they may also need to install additional pipe systems. If the vent is to go through the roof then scaffolding may be required and a roof stack would have to be installed and secured. All this can be expensive, time consuming and disruptive to work. It may also be impossible to discharge fumes outside, for example if the building is rented or the laser is say, in the middle of a shopping centre or office block.
Any holes made in the walls or ceiling would need to be properly sealed to prevent water leaks and if the laser is moved to another room then the holes would have to be sealed up completely and re-drilled elsewhere. Discharging the fumes outside may also cause complaints from neighbours or the environmental authorities. There is also the risk that fumes may re-enter the workplace through open windows and doors.
Discharging air from the workplace to the outdoors can also increase energy costs as heated or conditioned air will be pumped outside.
The alternative to discharging fumes outdoors is to use an extraction and filtration system such as the Xbase™ from Purex International Ltd.
The Xbase connects to the engraving laser in minutes using a short length of flexible hose and extracts hazardous fumes using powerful flow controlled blowers. The fumes are then drawn through a patented, specialised filter system before clean air is returned to the workplace. Because the Xbase returns air to the workplace there is no need to cut any holes for ducting in walls or ceilings and no heated or conditioned air is lost.
The Xbase is easy to move around, so if the laser moves, the Xbase goes with it. It is quiet in operation and because no holes in walls are required it is ideal for use in shops, malls, kiosks, schools, engraving workshops and offices.
Another added bonus is that many lasers available on the market can sit on top of the Xbase meaning an additional laser stand is not required. The Xbase also has storage space inside it that can be used in a variety of ways.
The extraction rate is fully adjustable so problems like drag marks on the work can be avoided and the system can be configured to filter fumes from most engraving materials.
The Xbase is available from Purex or a worldwide network of stockists, for more information visit the website _URL_

Ἀνδρεία, Τόλμα, Θράσος - Male and Female Courage in Classical Greek Literature
Sammanfattning: This thesis discusses the differences in the descriptions of and the attitudes towards female courage in the literature of the Classical period. Male authors of this period wrote extensively of the martial and virtuous courage of men, andreíā, yet in some instances instead labelled courage as tólma or thrásos. Tólma and thrásos are even more commonly used in descriptions of female courage, audacity or rashness. How these three words could be used in relation to men and women is discussed, and the fundamental belief of the Classical period that women were not capable of courage is encountered. As courage was outside the nature, phúsis, of a woman, her actions were always more likely to be viewed as tólma or thrásos. To what extent the literature of the period can reflect the lived experience of the ancient Athenian is unknown. However, it is concluded that literary works both impact and are impacted by social and cultural values, such as the view that women should not or could not be courageous.

(HealthDay)—For patients with esophageal cancer undergoing resection, surgeon volume, but not hospital volume, is independently associated with prognosis, according to research published online Jan. 7 in the Journal of Clinical Oncology.
To examine the influence of hospital and surgeon volume on survival after esophageal cancer surgery, Maryam Derogar, M.D., of the Karolinska Institute in Stockholm, and colleagues conducted a population-based cohort study involving 1,335 patients with esophageal cancer who underwent esophageal resection in 1987 to 2005. Participants were followed for survival until February 2011.
The researchers found that annual hospital volume was not independently associated with overall survival, and after adjustment for hospital clustering effects, hospital volume was not associated with short-term mortality. Mortality occurring at least three months after surgery was significantly reduced with a combination of higher annual and cumulative surgeon volume, with a hazard ratio of 0.78 for surgeons with both annual and cumulative volume above versus below the median. The association persisted after adjustment for hospital and surgeon clustering.
"In conclusion, this large and population-based cohort study provided evidence that long-term survival is independently influenced by surgeon volume but not hospital volume," the authors write.

By using entire islands as experimental laboratories, two Dartmouth biologists have performed one of the largest manipulations of natural selection ever conducted in a wild animal population. Their results, published online on May 9 by the journal Nature, show that competition among lizards is more important than predation by birds and snakes when it comes to survival of the fittest lizard.
Podcast: Lizards and Evolution
"When Tennyson wrote that nature is'red in tooth and claw', I think the image in his head was something like a Discovery Channel version of a lion chasing down a gazelle" said Ryan Calsbeek, an assistant professor of biology at Dartmouth College and a co-author of the study. "While that may often be the case, intense natural selection can also arise through competition. Sometimes, death by competitor can be more important than death by predator".
To show this effect, the researchers covered multiple small islands in the Bahamas with bird-proof netting to keep predatory birds at bay. Other islands were left open to bird predators, and on still other islands, the researchers added predatory snakes to expose the lizards to both bird and snake predators. Next, they tracked the lizards over the summer to record which lizards lived and which died on the different islands.
"We found repeated evidence that death by predators occurred at random with respect to traits like body size and running ability" said Robert Cox, a post-doctoral researcher at Dartmouth and Calsbeek's co-author. "But we also found that increasing the density of lizards on an island consistently created strong natural selection favoring larger size and better running ability."
Calsbeek and Cox explain that in high-density populations, the intensity of competition for food, space, and other resources is likely to increase. In turn, this increased competition favors the biggest, toughest lizards on the island.
"The lizards play for keeps," said Calsbeek, "and there's no room for the meek when times get tough".
Though the researchers note that competition will not always be more important than predation in other species or in different environments, they emphasize that their study has broad social implications because it demonstrates the ability to conduct evolutionary experiments in natural animal populations.
"Many people are skeptical of evolutionary biology because they perceive it as a purely historical science that can't be tested experimentally. Here, we're providing a real experimental test of natural selection as it happens in the wild. That's an exciting way for us to advance the public's perception of evolution" said Calsbeek.

text: Truso, situated on Lake Drużno, was an Old Prussian ( Pomesanian) town near the Baltic Sea just east of the Vistula River. It was one of the trading posts on the Amber Road, and is thought to be the antecedent of the city of Elbląg (Elbing). In the words of Marija Gimbutas, "the name of the town is the earliest known historically in the Baltic Sea area". The main export goods of Truso were amber, furs, and slaves, while blacksmithing and amber working were the major industries. The beginnings of the town can be dated back to approximately the end of the 8th century, while in the second half of the 10th century, the town declined and was eclipsed as a trade center by nearby Gdańsk.

Why LLBLGen Pro v3.0 is better than the regular designer for EF v4.0
As a comment to my blogpost about the 12 minute long video of LLBLGen Pro with Entity Framework v4.0, Burton Roberts asks:
Could you list the advantages of using llblgen pro 3 with Entity Framework versus using EF alone?
Of course! Now, I know these posts are often classified as'marketing' but so be it.
Why is the LLBLGen Pro v3.0 designer better for Entity Framework v4.0 than the regular Entity Framework designer? Below I'll give an (incomplete) list of features you have at your disposal with LLBLGen Pro v3.0 which you don't have with the EFv4 designer.
 - LLBLGen Pro's designer can handle massive models with thousands of entities.
 - Single entity, multiple target databases (e.g. an entity can have mappings to a SQL Server table and a MySql table in the same project)
 - Grouping of entities in the project: as a visual grouping system (so single output project) or as 1 output project (and thus edmx file / code base) per group.
 - Fine-grained reverse-engineering features, for full control over how names are created for fields, navigators, entities and the like: patterns for navigator names, pascal casing of names even if they're uppercased, '_' removal, abbreviation replacement, pluralization/singularization, fragment stripping from fields, tables, views and procs (e.g. 'tbl_', 'pr_', both suffix and prefix), auto-grouping of elements based on schemas.
 - Configurable reverse-engineering so you decide what follows what: do model relationships follow FK constraints in the database or not (e.g. when the DB doesn't have FK constraints, and you don't want to lose the manually created relationships). The same goes for unique constraints, primary key fields, field length/precision/scale etc.
 - True model-first development: tracking of changes made to the the relational model data in the project, and these changes are exportable as UPDATE DDL SQL scripts, including renames of tables, fields etc.
 - Unique constraint support: you can define which fields are unique so a unique constraint is created using model-first techniques
 - Model views: you can define multiple visual views on the entire project, including documentation, which help you focus on smaller areas of the project and also make it easier to discuss model details with domain experts
 - Productive ways of creating a model from scratch using Quick Model. Quick Model is a text-based DSL coupled with a visual representation which allows the user to very quickly create a model from scratch using text sentences. The elements created are added to the main model, and the feature can be used to specify a model quickly during an interview with a domain expert. The domain expert can then immediately see whether the model is correct or needs adjustment, as it doesn't take extra time to create it. As it's the same model the developers will work with there's no time lost by re-creating from scratch a'real' model based on a report from the interview with the domain expert
 - Powerful entity / complex type editing tools: all fields are displayed in a grid and you can define new fields with all specifics from the keyboard without moving your hands (see the quick model video above). No need to mess with a property grid.
 - Automatic forward mapping of fields, entities: auto-map model-first created entities and fields to existing elements or auto-create new tables from the entity definitions
 - Fine-grained control over generated relational model data: when using model-first, you generate tables from entity + mapping data. To make this as easy as possible, you want to define whether you want 'CustomerId' be generated as 'CustomerId', 'CUSTOMERID', or 'CUSTOMER_ID' (or even 'customerid' or other variants). This is important for case-sensitive databases like oracle and postgresql. Also you'd want to define whether you want natural character string types, currency types over decimals and variable types (e.g. varchar) over fixed length types (e.g. char).
 - Powerful search based on C# / VB.NET linq queries: to obtain information about elements in the project, you can define a linq query inside the designer to obtain the information you need, using the projection you need, and even export the information to excel or other program.
 - Automatic relational model management based on mappings: say you have 100 tables in your database, and you use 90 of them in mappings. LLBLGen Pro can warn you about these 10 tables which aren't used, can automatically remove them for you (through an UPDATE DDL SQL script), exclude them from the project (so they're not used in the project but also not removed from the db) without any effort from your side. This also goes for fields, it can automatically remove unused fields from mapped tables if you want (or warn you instead, or be totally silent about this, your choice)
 - Attribute definition for elements: no more 'buddy' classes needed. LLBLGen Pro v3 has a 2-step settings system where you can define defaults which are then used for all instances of the type the setting is specified for (e.g. for the type 'entity', setting A, B and C are set), which can then be overruled at the instance level (e.g. the 'Customer' entity). You can use this to specify an attribute for the type 'field' at the project level, which is then available for each field, and generated into the code for that field.
 - Task based code generation using powerful templates. You can easily control which code is generated using the task-based code generation, using templates which can be edited inside the designer. The code generated is placed in separate VS.NET projects using normal classes and namespaces, so it looks like code you'd have written yourself.
 - Errors produced by validation contain suggestions how to fix them, often with 1-click fixes inside the suggestion. The errors produced by the validation system can have one or more suggestions to fix the error, and each of them has a link you can click which either fixes the error for you or opens the editor for you of the element containing the error so you can directly focus on fixing the error without having to mess with XML files.
 - Clever inheritance modeling: not only can the designer automatically find inheritance hierarchies for you, it also cleans up elements no longer needed from subtypes if you make A a subtype of B. For example, A and B share a 1:1 relationship over their PK's. When you make A a subtype of B, this relationship has to go, and A's PK is inherited from B. Also fields in A which have the same name as B's have to go, as that would lead to errors. This is automatically done for you.
 - Define Target Per Entity Hierarchy (all entities in the hierarchy are mapped onto the same table) discriminator field values in the designer and use them in model-first scenarios.
I'm sure I've forgotten things, as well as not pointed out extra features the designer offers on top of the target framework, like typed lists, fields mapped onto related fields and the like.
LLBLGen Pro v3 is scheduled to be released at the end of May 2010.

As Brian Agnew points out, 5 minutes is entirely manageable, if somewhat wasteful of resources, if one can control timeout settings. Otherwise, at least two requests must be made: The first to get the result-producing process rolling, and the second (and third, fourth, etc., if the result takes longer than expected to compile) to poll for the result.
Brian Agnew and Darrel Miller both suggest similar approaches for the two(+)-step approach: POST a request to a factory endpoint, starting a job on the server, and later GET the result from the returned result endpoint.
While the above is a very common solution, and indeed adheres to the letter of the REST constraints, it smells very much of RPC. That is, rather than saying, "provide me a representation of this resource", it says "run this job" (RPC) and then "provide me a representation of the resource that is the result of running the job" (REST). EDIT: I'm speaking very loosely here. To be clear, none of this explicitly defies the REST constraints, but it does very much resemble dressing up a non-RESTful approach in REST's clothing, losing out on its benefits (e.g. caching, idempotency) in the process.
As such, I would rather suggest that when the client first attempts to GET the resource, the server should respond with 202 "Accepted" (_URL_ perhaps with "try back in 5 minutes" somewhere in the response entity. Thereafter, the client can poll the same endpoint to GET the result, if available (otherwise return another 202, and try again later).
Some additional benefits of this approach are that single-use resources (such as jobs) are not unnecessarily created, two separate endpoints need not be queried (factory and result), and likewise the second endpoint need not be determined from parsing the response from the first, thus simpler. Moreover, results can be cached, "for free" (code-wise). Set the cache expiration time in the result header according to how long the results are "valid", in some sense, for your problem domain.
I wish I could call this a textbook example of a "resource-oriented" approach, but, perhaps ironically, Chapter 8 of "RESTful Web Services" suggests the two-endpoint, factory approach. Go figure.

Eggs can taste delicious if cooked properly to stop the smell.

An egg salad whether on its own or in a sandwich is easy to make and can taste delicious but the smell can be off-putting. Eggs can produce a sulphuric smell caused by over cooking. These egg proteins can become over coagulated and this creates an excess of hydrogen sulphide, which causes the eggy smell.
Fortunately, there are a few simple steps to prevent this from happening.
Place the eggs in a saucepan of cold water so that they are fully submerged. Add 2 teaspoons of white vinegar and bring the water up to a simmering point. Continue to simmer for 7 minutes. The vinegar will neutralise the odour without affecting the taste of the eggs.
 - Place the eggs in a saucepan of cold water so that they are fully submerged.
Remove the saucepan from the heat and remove the eggs. Submerge the eggs in the bowl of cold water and leave for 2 minutes. The cold water stops eggs from continuing to cook inside their shells and prevents the yolk from turning a dark greyish or green colour. Discoloured yolks are a result of a reaction that increases the sulphur smell.
Peel the eggs to remove the shells. Store the eggs, covered in the fridge until you are ready to make the rest of your salad.
To remove any lingering smells from your kitchen, boil a saucepan of water with 1 teaspoon of vinegar for 5 minutes. Discard the water. The smell of vinegar will disappear quickly.

Sobre o livro
Message is one of the greatest poems in the whole of Portuguese literature. It was also Fernando Pessoa's only book written in Portuguese to be published during his lifetime. At the time of its release, in October of 1934 (just over a year before the author's death), Europe of the Enlightenment and freedom was succumbing to the advance of modern dictatorships, the escalation of expansionary nationalisms and a brand of imperialism based on atheistic materialism which, half a decade later, would trigger the Second World War.
It is out of this atmosphere of general European decline, and with unwavering focus on his own country in particular, that Pessoa orchestrates his Message: a telling of the great events and protagonists behind the genesis of Portugal, of the golden age of maritime discovery and of subsequent national entropy, all of it predictive and flowing towards the future construction of a new and different empire: the Fifth Empire, which, in the author's vision, would be a matrix of spirituality, messianism and millenarianism.
Introduced and annotated by António Apolinário Lourenço, the present bilingual edition of Message offers to its readers both a guide for understanding and an interpretation of the poem in light of the history of Portugal and the doctrines of esoteric and heterodox Christianity, all of which played a central role in the intellectual education of Fernando Pessoa.

The Southern Darter ( Sympetrum meridionale ) is not a common species in Southern Spain and care is needed to confirm identification. Where it is found in larger numbers it is never as abundant as the other Sympetrums. Breeding habitat is in waters with plenty of emergent vegetation and even marshy areas. These photographs were taken in wet areas off the Canuelo shown.
KEY I/D FEATURES
The virtual absence of any black abdominal markings, particularly on Segments 8 and 9, are a good indicator. On the sides of the thorax there are narrow black lines along the sutures. The legs have more yellow than black in them.

Life Science: Bottle Biology
Bottle Basics: Stringing Bottles
Bottle columns do not have to be strung and hung up but there are several advantages to doing so. By stringing bottles, you can:
- access different segments of your system more easily;
- stabilize your system and hold joints together better;
- transport your system more easily; and
- increase the chances that kids and/or pets will not knock your system over.
- Use a soldering iron (a hole punch works too, but holes are more
prone to ripping out) to make holes on each side of the bottle above
and below each joint.
- String nylon craft cord (string works too but is prone to decaying if it stays wet a long time) up one side and down the other, alternating between from outside in and from inside out.

Internet handshake extends the human touch
Scientists have developed a means of shaking hands across continents by using the internet to transmit such properties as grip, movement, even skin texture.
How the device works
Virtual handshake: How the device works
Scientists have developed a means of shaking hands across continents. Using the internet, the new technology can transmit such properties as grip, movement, even skin texture - everything, in fact, but actual physical contact.
A device that allows computer users to "feel" things online means that old friends thousands of miles apart could shake hands for the first time in years, a mother could soothe her child's troubled brow from miles away or even send a kiss via the web.
With the aid of a series of tiny motors and pressure pads built into a glove, users can transmit information about the position of their fingers, strength of touch and even the feel of their skin.
Prof Alan Marshall, from the department of electrical engineering at Queen's University, Belfast, who has been developing the "haptic" or touch technology, believes it will make using the internet a far more "complete" experience.
He tested a prototype of the technology by conducting a virtual handshake between one person in Belfast and another at BT's research laboratories in Ipswich.
The pair could see each other on their monitors and were able to feel their hands grasping, despite being more than 300 miles apart.
Prof Marshall is now developing the technology so that internet users will be able to "feel" their way around and even handle products while shopping online.
He said: "Almost since its conception, the internet has really only used two of the senses - visual and audio. It will have to enhance the experience by making it more realistic.
"Haptic devices give the illusion of actually being able to shake hands, or move an object like a cup around a screen while actually feeling what it is like."
Prof Marshall and his team are working with companies in America and Canada to create sensory products that can be used over standard connections and compensate for the variable download speeds that might be expected to interfere with the "realism" of the -experience.
He claims, however, that it will be possible to send detailed touch information over normal networks and even to embed information about the physical properties of objects in photographs on web pages.
That would mean, for example, that online stores could let shoppers handle their products before they buy. There are also interesting possibilities for computer games, which could be made to seem more realistic.
Prof Marshall said that he expected haptic devices to be commonplace within about five years, perhaps even replacing the computer mouse.
He said: "The motors give the impression that you can touch the object, and you can embed different properties such as sponginess, tactile sensation and grip strength in an object on a screen.
"Take games consoles such as the Nintendo Wii, which have already given players the ability to control their screen characters with their own movements.
"Imagine what it would be like if you could play as a virtual tennis player and feel every impact of his serve."
Prof Nigel Shadbolt, president of the British Computer Society, said: "Allowing people to feel directly what they are seeing on a computer screen is a Holy Grail.
"While it is challenging, I am certain it is coming and will open up the internet like never before."

When photography was first introduced and became popular, it was a lengthy process, with prolonged exposure times and the requirement for the sitter to remain still throughout the process. This proved to be particularly difficult when dealing with children, and photographers often dreaded their visits to their studios. Neck and back braces might be used to help to prevent the child from moving during the photography, and this helps to explain the rather fixed look on the faces of many children.
As exposure times shortened, children were photographed more frequently. Wealthy families had their children photographed at least once a year to record growth, and important stages in development were symbolised by a change in clothing style. Little boys wore dresses until about the age of five, then short trousers until about twelve, when they adopted long trousers like adult men. The age of girls was indicated by the length of their skirts: short for little girls, calf-length for teenagers, and ankle length after 17, when they were considered grown up.

How to fix: fail to boot Ubuntu using USB
I always prefer using a USB to install Ubuntu or any other Linux distro because it is easier, more convenient and faster than using a CD or DVD. However, yesterday a friend of mine got an error when trying to use a USB to boot Ubuntu. When he booted up using the USB, the bios of his laptop display an error " Bootmgr is missing, Press Ctrl+Alt+Del to restart". Here is the picture of the error:
bootmgr is missing
The reason of this error is that the file system type of the USB is NTFS. To make the USB work, you need to change its file system into FAT first before using UnetBootin to create the bootable USB.
To format a USB stick, you can use Gparted or other similar tools with a GUI. However, the cooler way is to use the command line. Here I will show you how to do that:
First, plug the USB in then run the following command as root to find out the name of the USB:
 sudo fdisk -l
After you ran this command, you will see the name of the USB ( usually /dev/sdb1)
Next, you just need to run the following command to format the USB into FAT file system:
 sudo mkfs.vfat /dev/sdb1

Director Van Ling, talks to New Greek TV about "Cliffs of Freedom", the story of the Greek War of Independence
CLIFFS OF FREEDOMis a romantic historical epic film, that is the first Hollywood feature film to tell the story of the Greek War of Independence of 1821. The film was a passion project since the 90s, for Executive Producer and Co-writer Marianne Metropoulos, who spent several years developing a story that would bring the Greek war for independence alive for modern audiences. Along with Hollywood's veteran film Producer, Casey Cannon, Director Van Ling, and Executive Producer, Dean Metropoulos, Cliff's of Freedom tells the story of Greece's struggle for freedom after centuries of iron rule and oppression by the Ottoman Empire.
The film's cast includes; Tania Raymonde (Lost, Cloverfield, Goliath), Academy Award winner Christopher Plummer (The Sound of Music, Beginners, The Last Station), Billy Zane (Titanic, Dead Calm) and Raza Jaffrey (Homeland) depicting the start of the Greek War of Independence. Famous actors of Greek descent join the cast including, Billy Zane and Kosta Mandyllor.
The film stars Tania Raymonde as Greek freedom fighter Anna Christina. Cliffs of Freedom is love story between a young Greek girl and a Turkish Ottoman Colonel during the dawn of the Greek War for Independence, the film is directed by long-time James Cameron collaborator Van Ling (The Abyss, Terminator 2, Titanic).
Cliffs of Freedom is inspired by historical events that occurred almost two hundred years ago. The story sees conflicted Turkish colonel Tariq spare the life of 12 year old girl, Anna Christina. Years later the two are eagerly reunited, but as the Ottoman empire continues its reign of terror on Greece, Anna Christina is compelled to join the Greek rebellion and lead the fight against the man she loves.
Yanna Darilis caught up with the Director Van Ling, to talk about bringing these historical events to life through this story.
YD: What inspired you to tell this story about this period of Greece's history? Did you have knowledge about these historical events prior to this script; what impacted your emotions the most about this story?
VL: Well, as is appropriate for this film, it started with a woman: a Greek-American named Marianne Metropoulos had come up with a story idea in the mid-90s about a Greek village girl who falls in love with a Turkish officer, and wanted to develop it into a film. She spent many years working with different Hollywood producers, but it was only when my producing partner Casey Cannon came on board around 2010 did things really start to go somewhere. This was partly because Casey's a strong and determined woman, and also because with over thirty years of experience in the film business, she knew how to produce it, yet was not tied to the usual studio mentality where they assess any project based solely upon its potential box office return. There was literally almost no interest in mainstream Hollywood for stories that took place in this historical period, unless it could be done for little to no budget… which would not have done justice to any story that touched upon the Greek War of Independence. Casey took it on as a challenge to help Marianne get the film made in a way that would do the best justice to her story and reflect Marianne's sense of passion for it.
So during the many years she worked with Marianne on honing the story and explore the logistics of making it, Casey would bring me in as a creative consultant. She and I would brainstorm how to get from point A to point B in Marianne's original story, and I would make suggestions and Casey would say "why don't you write that up?" So what started as story notes became full scene descriptions and dialogue suggestions, and by 2014, I had done a complete rewrite of the entire story and script, and was invested in the storytelling. I think that's why Marianne ultimately decided to ask me to direct the film.
I love history and doing research, so I was fascinated by this period of world history that I knew nothing about when I started. And one of the things we as filmmakers try to do is find and focus on things that resonate emotionally with other people, not just the culture at hand, so it's not just a foreign story from a distant time and place, but a human one that is relatable to what's going on now. And it seems that revolutions, hope and resilience never go out of style. Also, the opportunity to try to work with and develop a strong female protagonist, just as I had watched my mentor James Cameron do in each of his films, was fantastic.
YD: Films based on history tend to have two sides of the story at times, how important was it to stay true to the facts, and what kind of team did you compile to make sure that the history was portrayed as it truly was?
VL: As a first generation Chinese-American born in the US, it was very interesting to see the parallels and differences between cultures and try to bring a more objective view of the historical events as recorded. But in this case, even our Greek historical consultant, Eleni Drivas, noted that there is "no consensus" as to all of the facts in this period of Greek history. It's interesting and fraught when one culture's or faction's or person's facts are another one's propaganda. Everyone is certainly entitled to their own opinions, but if you're the kind of person who balks at the fact that a Greek and a Turk could fall in love, then maybe this movie is not for you!
For my part, I tried to find a balance between compelling storytelling and historical accuracy. I always want to do both, but the challenge here was that it was like "Rashomon" in terms of the actual historical facts. Marianne said to me at the start of the project: "when in doubt, ask a Greek"; and that's what I did… and I quickly found out that each and every Greek person has a different upbringing and opinion as to what actually happened, or what to say, or even how to make the sign of the cross, based on what they were taught… and each one of them is vehemently adamant that their way is the only way. The old joke that even Marianne told me was that if you put two Greeks in a room, you will get three opinions… this is why the Greeks had to invent democracy! So at a certain point, I tried to find a balance, which was tough when everybody disagrees with each other on every little detail except on the fact that I was portraying it wrong! So there was a lot of narrative instinct and compromises throughout the process. But I hope I was able to capture the spirit of Greece and reveal some common humanity in a story that mixes fictional characters and events with real historical ones, since we were not making a documentary here.
YD: Tell us about the fictional Romeo and Juliet element, and why it was important to tell this story?
I really can't speak for Marianne Metropoulos, but I believe she wanted to celebrate her Greek heritage but also do a romantic storyline that was universally relatable, with themes of family and honor and vengeance… and to also say that love can make a difference in bridging entrenched cultural hatreds and bringing about change, through deeds or through inspiration. At least those were the aspects that I latched onto as elements in which everyone could find personal meaning, not just Greeks and Turks. In stories of war and oppression and sacrifice, there is often a tendency to focus on the hate and the atrocities and to forget that there are human beings and personal emotions at the core of every conflict on both sides… and these can either be used to further divide people and perpetuate hatred between cultures, or they can be used to understand, mend and heal… often at great cost.
 YD: Greece's history is vast and the heroic spirit is portrayed throughout time in various historical accounts of wars, what were you looking for in a producing partner and director in order to capture the essence of this historical story, and what made you decide to work with producing partners Maria Metropoulos and Casey Cannon, to bring this story and these characters to life.
VL: It seems to me that the history of Greece is a history of tenacity and determination, and it took a whole lot of both to get this movie made. At a screening recently, one Greek viewer told me that this film was 200 years in the making, which is certainly both a humbling thought and a responsibility I took very seriously when directing the film. I had worked with Casey for almost thirty years, and I could see that Marianne had the gumption and wherewithal, just not the experience in filmmaking… but that's where Casey and I came in. So it was about finding partners who were able to collaborate and respect each other under fire, which is always a challenge. But I'm very grateful to Marianne and her husband Dean Metropoulos for trusting me with her very special passion project, and I'm forever grateful to Casey for fighting alongside me and inspiring me every step of the way. It's been an honor to work on this film.
YD: The _TAG_ is movement in the production notes. I'd like to know more about the movement's relevance

Singing Capacitors and Whining Inductors
A Practical Introduction to Acoustic Cryptanalysis
Dan Hagon
In this talk we provide a practical introduction to Acoustic Cryptanalysis using tools and techniques that are easily grasped and cheaply available. The intention is not to present any new results, but instead the emphasis is on gaining a foundation in the theory of such attacks, so that you will be able to apply them more effectively in more challenging scenarios. As we shall see, such attacks are an extension of other types of side-channel attack (timing and power analysis attacks in particular), with the added promise of bridging air gaps.
