6 New Weapons That Are Making War Look Like a Cartoon
#3. Transformer TX
The robot's teeth marks have healed, and you return to the battlefield of the future, encouraged because your sergeant has told you that the new Transformer TX will be entering service soon. Can it be? You haven't dared to imagine Transformers would have a place on the battlefield since you were 13 or so.
Before you get too excited about this one, though, we have to clear something up. A Transformer is a car that transforms into a giant robot and saves the universe. A Transformer TX, on the other hand, is a car that transforms into ... well, a car, only with wings and helicopter blades.
And that's pretty much it. It's kind of the Transformer you drew on the back of your notebook when you were eight. It's a jeep with helicopter parts stuck to it. The entire concept for this one is, "Let's put helicopter parts on a Humvee and see what happens!" Then someone else said, "Wait ... what if we add wings to it, too?" and everyone in the room just started clapping.
"Johnson, you genius."
This was commissioned by DARPA, which means they literally don't give a shit how ridiculous it looks. DARPA is the Pentagon's research wing, and its mission is "to prevent technological surprise to the U.S." which means it's paid to seriously consider every single idea that comes its way, no matter how stupid it sounds. It's only natural that the researchers' common sense should become atrophied after a while. The problem is that sometimes those ideas get approved, and DARPA ends up adding giant dinosaur legs to a submarine or something. But in this case, it could've been much worse -- here's a rival bid for the Transformer TX:
That looks like rejected concept art for a 1968 film called 2010: When Everything is Helicopters.
The Transformer TX is capable of seating four people and has an automated takeoff system, which means that soldiers don't have to know how to pilot a plane to get it off the ground. How do they land it if none of them has aviator skills, you ask? Well, um ...
"They don't. They live in the sky and have wild adventures."
"Johnson, you're on fire today."
The Pentagon hopes to get some prototypes in the air by 2015, which is real lucky, because we heard we won't be roads by then.
#2. Powerswim
So you're still a soldier of the future, and you're on a mission where you need to stealthily swim behind enemy lines, hopefully ending the trip by slowly emerging from the tide with a knife in your teeth. But you're not just swimming, because this is THE FUTURE. No, you'll be using a Powerswim.
Aka "The Dick Glider."
Like the Kitty Corner Shot, the Powerswim is a relatively simple contraption: It's a "human-powered swimming device" capable of making swimmers move 150 percent faster than normal with the same amount of effort. It was designed by DARPA to help Navy SEALs reach their destinations quickly without the use of a submarine, a motor propeller or anything else that is cool.
Nope, this shit is old hat.
But what's so ridiculous about it? Well, for starters, it makes you look like a giant dork, as the head of the project kindly demonstrates in this mine of unintentional comedy gold:
He even mentions bringing the Powerswim to his pool and teaching 25 people to use it, in what was probably the saddest birthday party ever.
"I'm a genie in a bottle. ... It helps if you sing it, guys."
There's also the small inconvenience none of the articles or videos about the Powerswim thinks to mention: the fact that it seems to be constantly slapping your junk.
"It's actually quite pleasurable."
The Powerswim was designed to be swiftly removed mid-swim and dumped in the sea, like in case someone else swims by and you're ashamed to be seen in it. We also can't imagine it being that easy to take off, unlike the piece of equipment it's meant to replace:
The Powerswim 1.0.
The Powerswim is "currently in the packaging stage," as the Pentagon's top scientists presumably try to figure out how they fuck the can fit this thing into a decent-size box and, if possible, design a logo that doesn't look completely ridiculous.
The only thing that would look sillier would be, we don't know, shoving the swimmer inside a torpedo and firing him at the enemy.
#1. Underwater Express (Human Torpedoes)
Ah, here we go. As you find yourself zipping through the water in a huge bullet, this will be the precise point at which you, the soldier of the future, realize you are living in a Wile E Coyote cartoon.
The Underwater Express is either a submarine shaped like a torpedo or a torpedo capable of carrying people inside it, depending on how you prefer to think of it. This thing can go twice as fast as the fastest submarine in the world, leaving a trail of exploding dolphins and baby seals in its path.
"There has to be some way we can make sailing hundreds of feet underwater in a metal can less safe."
How is this possible? Well, the Underwater Express uses something called "supercavitation," which is when a bubble of gas is formed around a speeding object, allowing it to move much faster than it should. This effect is usually reserved for torpedoes, which, as a reminder, are commonly intended to crash into things and explode.
One of the big drawbacks for torpedoes that use this method (like the Russian Shkval) is that they're not super-good when it comes to maneuverability and steering. It's bad enough when we're talking a big block of explosives, but what about when they're transporting important stuff like, oh, people? In fact, they're currently testing a 100-knot prototype of the Underwater Express just to see if they can steer it at all.
The fact that this thing looks like a bullet isn't exactly encouraging.
If all goes well, the military plans to set up a comprehensive network of human torpedoes ferrying people and materials across large bodies of water, totally not crashing into one another. The Underwater Express was conceived by (you guessed it) DARPA, probably after someone there saw this poster:
"Who is that man and how is he doing that?! Find him now!"

I have a C++ application I'm in the process of optimizing. What method or tool can I use to pinpoint where exactly my code is running slowly?
We started with Q&A. Technical documentation is next, and we need your help.
Whether you're a beginner or an experienced developer, you can contribute.
closed as off-topic by Andrew Medico, lpapp, Reto Koradi, EdChum, Raul Rene Jul 22 '14 at 7:38
This question appears to be off-topic. The users who voted to close gave this specific reason:
If your goal is to use a profiler, use one of the suggested ones.
However, if you're in a hurry and you can manually interrupt your program under the debugger while it's being subjectively slow, there's a simple way to find performance problems.
Just halt it several times, and each time look at the call stack. If there is some code that is wasting some percentage of the time, 20% or 50% or whatever, that is the probability that you will catch it in the act on each sample. So that is roughly the percentage of samples on which you will see it. There is no educated guesswork required. If you do have a guess as to what the problem is, this will prove or disprove it.
You may have multiple performance problems of different sizes. If you clean out any one of them, the remaining ones will take a larger percentage, and be easier to spot, on subsequent passes. This magnification effect, when compounded over multiple problems, can lead to truly massive speedup factors.
Caveat: Programmers tend to be skeptical of this technique unless they've used it themselves. They will say that profilers give you this information, but that is only true if they sample the entire call stack, and then let you examine a random set of samples. (The summaries are where the insight is lost.) Call graphs don't give you the same information, because
They will also say it only works on toy programs, when actually it works on any program, and it seems to work better on bigger programs, because they tend to have more problems to find. They will say it sometimes finds things that aren't problems, but that is only true if you see something once. If you see a problem on more than one sample, it is real.
P.S. This can also be done on multi-thread programs if there is a way to collect call-stack samples of the thread pool at a point in time, as there is in Java.
P.P.S As a rough generality, the more layers of abstraction you have in your software, the more likely you are to find that that is the cause of performance problems (and the opportunity to get speedup).
Added: It might not be obvious, but the stack sampling technique works equally well in the presence of recursion. The reason is that the time that would be saved by removal of an instruction is approximated by the fraction of samples containing it, regardless of the number of times it may occur within a sample.
Another objection I often hear is: "It will stop someplace random, and it will miss the real problem". This comes from having a prior concept of what the real problem is. A key property of performance problems is that they defy expectations. Sampling tells you something is a problem, and your first reaction is disbelief. That is natural, but you can be sure if it finds a problem it is real, and vice-versa.
ADDED: Let me make a Bayesian explanation of how it works. Suppose there is some instruction
Then suppose we take just 2 stack samples, and we see instruction
The last column says that, for example, the probability that
Suppose the prior assumptions are different. Suppose we assume P(f=0.1) is .991 (nearly certain), and all the other possibilities are almost impossible (0.001). In other words, our prior certainty is that
Now it says P(f >= 0.5) is 26%, up from the prior assumption of 0.6%. So Bayes allows us to update our estimate of the probable cost of
Yet another way to look at it is called the Rule Of Succession. If you flip a coin 2 times, and it comes up heads both times, what does that tell you about the probable weighting of the coin? The respected way to answer is to say that it's a Beta distribution, with average value (number of hits + 1) / (number of tries + 2) = (2+1)/(2+2) = 75%.
(The key is that we see
So, even a very small number of samples can tell us a lot about the cost of instructions that it sees. (And it will see them with a frequency, on average, proportional to their cost. If
You can use Valgrind with the following options
It will generate a file called
I assume you're using GCC. The standard solution would be to profile with gprof.
Be sure to add
I haven't tried it yet but I've heard good things about google-perftools. It is definitely worth a try.
Related question here.
A few other buzzwords if
Newer kernels (e.g. the latest Ubuntu kernels) come with the new 'perf' tools (
These come with classic sampling profilers (man-page) as well as the awesome timechart!
The important thing is that these tools can be system profiling and not just process profiling - they can show the interaction between threads, processes and the kernel and let you understand the scheduling and I/O dependencies between processes.
OProfile is good, because it makes it much easier than Gprof to profile multiple programs at once. You also can run it on your release build (if it has symbols), instead of having to build a special profiling build.
If you don't care about taking a massive performance hit (50x), Valgrind (Cachegrind) is good.
You can use callgrind. Together with KCacheGrind, it gives a pretty nice profiler. Besides that, Intel VTune is free for educational use on Linux. It is probably the best profiler out there. If you have an AMD CPU, use AMD Codeanalyst (succeeded by AMD's CodeXL), which is also available for Linux; this one is only decent, but free.
I would use Valgrind and Callgrind as a base for my profiling tool suite. What is important to know is that Valgrind is basically a Virtual Machine:
Callgrind is a profiler build upon that. Main benefit is that you don't have to run your aplication for hours to get reliable result. Even one second run is sufficient to get rock-solid, reliable results, because Callgrind is a non-probing profiler.
Another tool build upon Valgrind is Massif. I use it to profile heap memory usage. It works great. What it does is that it gives you snapshots of memory usage -- detailed information WHAT holds WHAT percentage of memory, and WHO had put it there. Such information is available at different points of time of application run.
This is a response to Nazgob's Gprof answer.
I've been using Gprof the last couple of days and have already found three significant limitations, one of which I've not seen documented anywhere else (yet):
This was GNU Gprof (GNU Binutils for Debian) 184.108.40.20680103 running under 64-bit Debian Lenny, if that helps anyone.
Oprofile is a decent free option, but I've had better luck using Zoom. It's a commercial (free eval) profiler for Linux that has a sweeet GUI for seeing hotspots in your source code.
google-perftools is the only reasonable alternative to Gprof I've found. It's quite usable, familiar, and I believe it's time sampling, so that I/O bottlenecks are revealed, in addition to the usual CPU bottlenecks that Gprof discovers. It's also significantly less invasive.
Use Valgrind
I am pretty sure you can use Cachegrind or some similar plugin to do profiling.
The answer to run
So this is what I recommend. Run program first:
Now when it works and we want to start profiling we should run in another window:
This turns profiling on. To turn it off and stop whole task we might use:
Now we have some files named callgrind.out.* in current directory. To see profiling results use:
I recommend in next window to click on "Self" column header, otherwise it shows that "main()" is most time consuming task. "Self" shows how much each function itself took time, not together with dependents.
You may have a look at Gprof, the GNU profiler.
Another interesting tool may be IBM Rational Quantify, but it's not free.
In addition to Intel Vtune / AMD CodeAnalyst, perfmon2 is an OSS alternative, that requires a patched kernel to open up the CPU performance counter, and that would give you various performance figures that you can gather.
perfmon2 is still implementation-specific, i.e. L2 cache misses are called different things on Intel Pentium III compared to AMD64, and they're beginning work on perfmon3, which should unify the API.
But generally, Gprof would work well enough for you to detect slow code.
You can use Sun Studio's collect/analyzer. Using collect you can also profile memory usage, threads, MPI, etc. You also get a nice timeline view of your program.
If you use these tools in Solaris you can also get hardware performance counter information like in vtune or oprofile.
You can get this (and other very useful tools from Sun) at Oracle Solaris Studio 12.3.
I've had very good luck with Rational Quantify (expensive but very good) and OProfile. Be aware when using OProfile that it's a statistical profiler, not a full-on tracing profiler like Quantify. OProfile uses a kernel module to poke into the call stack of every running process on every interval so certain behaviors may not be caught. Using multiple profilers is good, especially since different profilers tend to give you different data all of which is useful.
As for using Gprof, it's OK. I would get one of the graphical front-ends, since the data can be rather difficult to get through just on the command line. I would avoid Valgrind, until you require memory checking.
There is also LTTng. I've never used that one though, so I cannot tell how well it works. But one advantage it has is an userspace tracer. In some situations that could be rather nice to have.
Don't forget the poor man's profiler which is basically a wrapper for GDB so it can do sampling of where the threads "are" every so often. Basically it uses GDB to get the stacktraces for sampling, instead of lsstack, etc.
A little unrelated, but Gprof itself can do sampling profiling, as well: Use callgrind as a sampling profiler? ("Flat profile is based mainly on sampling")
And you can also use a USR1 signal et al to dump thread backtraces.
You can check out Gprof from the GNU Project.
Here are some quick start guides:
The PCT profiler takes the stack sampling approach advocated by other responders who did not suggest a specific tool.
It can do instruction-level or procedure-level profiling. I have used it to profile non-C code in addition to C code (I have used it previously for OCaml with interesting results).
Use SysProf; It's pretty good in doing quick profiling with minimum hassle. It shows information like how many times a function has been called, time spent in each routine, overall time spent for each function, etc. Just install, do the initial configuration and then run your application/service (no need to recompile, instrument your code).
You can try out AMD CodeXL's CPU profiler. It is free and available for Linux.
AMD CodeXL's CPU profiler replaces the no longer supported CodeAnalyst tool (which was mentioned in an answer above given by Anteru).
CodeXL supports several CPU profiling techniques for AMD CPUs (for non-AMD CPUs, only time based CPU profiling is supported).
For more information and download links, visit: AMD CodeXL web page.
These are the two methods I use for speeding up my code:
For CPU bound applications:
For I/O bound applications:
If you don't have a profiler, use the poor man's profiler. Hit pause while debugging your application. Most developer suites will break into assembly with commented line numbers. You're statistically likely to land in a region that is eating most of your CPU cycles.
For CPU, the reason for profiling in DEBUG mode is because if your tried profiling in RELEASE mode, the compiler is going to reduce math, vectorize loops, and inline functions which tends to glob your code into an un-mappable mess when it's assembled. An un-mappable mess means your profiler will not be able to clearly identify what is taking so long because the assembly may not correspond to the source code under optimization. If you need the performance (e.g. timing sensitive) of RELEASE mode, disable debugger features as needed to keep a usable performance.
For I/O-bound, the profiler can still identify I/O operations in RELEASE mode because I/O operations are either externally linked to a shared library (most of the time) or in the worst case, will result in a sys-call interrupt vector (which is also easily identifiable by the profiler).
Use a profiler as most people suggest. I would recommend Very Sleepy. Be aware that Visual Studio has a built-in profiler itself, but it depends on the sampling method; you may profile CPU or I/O operations.

5 Hilarious Ways Game Designers Are Messing With Pirates
#2. Spyro's Never-Ending Series of Traps
Via Covergalaxy.com
Damn, even cutesy children's games get pirated? Absolutely, they do. Spyro 2 had pirated versions floating around a mere week after its release, which put a significant dent in the game's sales. With Spyro: Year of the Dragon, Insomniac Games wanted to make damn sure that didn't happen again. What they did was nothing short of genius: Instead of throwing one giant fuck-you into the game somewhere, they turned the entire game into a series of middle fingers.
Insomniac developed a series of crack-protected traps. This meant that, even if a pirate successfully removed the original copy protection, the game would still be affected in ways that wouldn't be obvious until you attempted to play through it. Although it should have been obvious from the get-go, when a fairy politely informs you that you're a horrible person doing horrible things:
Via Tcrf.net
"Thank you in advance for licking all of our dicks. Please do have a miserable day."
After that screen, developers decided to see just how much time hackers had on their hands.
It starts small -- for instance, to progress in the game, Spyro needs to collect eggs and gems, just like a real dragon would. The pirated game, however, causes random gems and eggs to disappear from parts of the game you had not reached yet. Since those important items had vanished, the player was unable to continue past a certain point. Clearly the pirates figured out what was going on, and patched that particular problem.
But here's where the real genius of the plan falls into place: Fixing that layer of piracy glitches only exposed another. It would, at different times, prevent the players from pausing the game, keep them from using portals to advance further, and change the menu language to German.
It then enrolled you in a very open and public Nazi social club.
Finally, when all previous issues had been properly patched and the hackers could actually make it to the end of the game, they found that attacking the final boss would immediately send them back to the beginning of the game, with all of their save files erased.
The best part is: It worked. Most of a game's sales occur within the first couple of months, and it took over two months for a properly patched version of the game to become available to pirates.
#1. Game Dev Tycoon Plagues Pirates With Pirates
Game Dev Tycoon puts you in the shoes of a game developer whose goal is to make good games while making enough money to do all sorts of cool rich people shit, like buying food and paying bills.
The game's developer, Greenheart Games, decided to leak a hacked version of the game, mere minutes after releasing the legitimate version, just to see what would happen. Sure enough, within one day, a whopping 93.6 percent of players were playing the illegal version of the game. So now we have a game about making games pirated by pirates? How could this possibly be more meta? Simple: by sticking pirates in the pirated game.
The goal within the game is to build a successful gaming empire and make money. Well, people who stole the real game found that, if they made enough good fake games, they would eventually receive messages like this:
Via Greenheartgames.com
"P.S. We're standing right behind you."
Yup; people are stealing your fake game, and you are making no money. Sad face.
The thievery gets worse the further you progress in the game (you start in the 8- and 16-bit era, when game piracy was barely a blip on the radar) and the better you become at game design. That makes sense, after all -- better games mean more people want to steal them. So, releasing games with solid 9-10 ratings will result in increased piracy and decreased sales. Keep releasing awesome games, and the piracy will become so ridiculously rampant that your company is forced into bankruptcy.
And yes, the irony was lost on the pirates of the world. How else to explain cries for help like this one:
Via Greenheartgames.com
Come on, little buddy ... you're soooo close to getting the point. We know you can do it!
Or this:
Via Greenheartgames.com
So close!
The creator of the game, Patrick Klug, claims that he doesn't hate pirates, although his company doesn't seem to share his sunny disposition. At least that's how we interpret a quote like "If, years down the track, you wonder why there are no games like these anymore, and all you get to play is pay-to-play and social games designed to suck money out of your pockets, then the reason will stare back at you in the mirror." Ouch.

GENESEO, N.Y. - The State University of New York Board of Trustees has named David Geiger, professor and chair of SUNY Geneseo's chemistry department, a distinguished teaching professor. The distinguished rank constitutes the highest system tribute conferred upon SUNY instructional faculty.
Geiger is one of nine SUNY faculty members named a distinguished teaching professor this year (two in an honorific capacity). Fifteen other SUNY faculty received distinguished professorships: six were named distinguished professors for achieving national or international prominence within their field, and nine were named distinguished service professors (three in an honorific capacity). View complete list.
Geiger is among 40 Geneseo faculty members who have received the distinguished rank since 1973.
"It is with great pride that we recognize SUNY's most brilliant scholars and teachers and those whose service to the community and to SUNY merit the distinguished ranking," said Board Chairman Carl T. Hayden. "We are grateful for their contributions to our students, to SUNY, the communities we serve and the body of knowledge in their chosen field of inquiry."
The board said Geiger "employs a variety of best practices to engage his students and spark excitement about chemistry" but noted that his "unique contribution is the way he helps students develop self-confidence as learners and scientists by letting them know he recognizes their talents and has faith in their abilities."
The board also said Geiger's "ability to bring out the best in his student extends to the collaborative research he conducts with his undergraduates."

I'm currently a full time developer (9-6). I am also currently working on my own business idea in my free time. This business idea will take a fair amount of effort to get anywhere near completion.
In an ideal world I would like to be able to devote an extra ~20h a week to the project. So far I haven't been able to consistently achieve that, i'm really not used to working a 60h week and i have found motivation to be a big problem.
I have generally been doing a ~5h on both Sunday and sat and then a couple of ~3h sessions during the week.
Can anyone advise on the best way to manage working long periods? Is it better to work longer in the week and keep weekends free or is it better to spread your workload over a longer time so your not doing stupidly long days? Can anyone offer some advice on how to achive a longer productive week? Thanks

Our accreditations
Read about some of the accreditations we currently have and what they mean to us.
Fundraising Standards Board
The FRSB is the independent self-regulatory body for UK fundraising.
Being a member of the FRSB requires that we
- (i) comply with fundraising best practice,
- (ii) keep up to date with any changes; and
- (iii) handle any fundraising complaints appropriately.
Involvement in the scheme is intended to raise standards and build public confidence in fundraising. We signal our membership of the FRSB through the use of the "give with confidence" tick logo on all our fundraising and 'corporate' materials.
Our membership is reviewed and renewed on an annual basis.
If you have any questions or issues with our fundraising activities or practices you can contact our Complaints Co-ordinator by emailing firstname.lastname@example.com.
Check out our fundraising promise.
Information Standard
LGBT Foundation is a certified member of the Information Standard. This is a scheme that has been developed by the Department of Health to enable anybody to quickly identify trustworthy information regarding health and social care.
By being awarded the Information Standard, it means that the Department of Health is satisfied that the information we provide meets their standards.
To achieve the standard, LGBT Foundation has had to show that we produce information which is:
- accurate
- impartial
- balanced
- evidence-based
- accessible
We are grateful for any feedback we receive about our resources and information, so if you have anything you would like to tell us about any product, please let us know in the comments box. Any comments we receive will be kept and considered when we are updating our resources, which we aim to do every two years.
All resources that have the Information Standard logo on them have been produced in accordance with the Information Standard. Those web pages and resources that don't have the logo are not in scope of the Standard. This is very often because it is not related to health and social care, or because it was produced by an individual or organisation not working directly for LGBT Foundation.
The Lesbian & Gay Foundation tries to make sure that all our information is accurate and up to date. We take no responsibility for any error or omission, but we will endeavour to rectify any error or omission once it is brought to our attention. Neither the scheme operator nor the scheme owner shall have any responsibility whatsoever for costs, losses or direct or indirect damages or costs arising from inaccuracy of information or omissions in information published on the website on behalf of LGBT Foundation.
Investing In Volunteers
The Lesbian & Gay Foundation were first awarded with the Investors in Volunteers chartermark in May 2008; we recently achieved re-accreditation until 2015.
Volunteers are involved in all aspects of LGBT Foundation's work from being a trustee, to delivering face to face counselling sessions to giving out information and resources in the Village. We could not do what we do without volunteers so the Investors In Volunteers chartermark is really important to us as we feel it demonstrates our complete commitment to providing a safe, inclusive and empowering environment to volunteer in.
The Investors in Volunteers application process involves working with an assessor who supported us to complete a self-assessment and action plan, went through our policies and procedures and visited our offices to interview volunteers and staff members to check we are meeting quality standards.
This really positive process highlighted the amazing work our volunteers are doing and the impact they are making on the lives of the lesbian, gay and bisexual community.
LGBT Foundation are really proud to hold the Investors in Volunteers award.
Investors in People (IiP)
We received Investors in People accreditation in 2010.
For us, accreditation means that are staff are important to us, and that we have the right structures and processes in place to support and develop them.
IiP is a tool to liberate innovation, creativity and quality from all our staff, to help us to provide the best possible services and support to the people who use our services. It is based on the concept of 'Plan, Do, review', and means that we are always striving to continuously improve.
Our needs, and the needs of our staff, change constantly, and IiP allows this flexibility.
Since being IiP accredited, we have seen our staff team grow in size, and the services and support we offer grow in tandem.
Positive about Disabled People
LGBT Foundation has been a member of the Positive about Disabled People Scheme, which is run by Jobcentre Plus, since 2007.
As part of the scheme, we make five commitments regarding recruitment, training, retention, consultation and disability awareness.
These commitments are:
- to interview all disabled applicants who meet the minimum criteria for a job vacancy and to consider them on their abilities
- to discuss with disabled employees, at any time but at least once a year, what both parties can do to make sure disabled employees can develop and use their abilities
- to make every effort when employees become disabled to make sure they stay in employment
- to take action to ensure that all employees develop the appropriate level of disability awareness needed to make these commitments work
- to review these commitments each year and assess what has been achieved, plan ways to improve on them and let employees and Jobcentre Plus know about progress and future plans

TouchMail - Email for the touch
Hi all,
I'd like to share my attempt at the Sencha Touch Contest (Which did not make it to the top 10)
What I have is an email application with multiple account support, contacts and signatures.
All pretty standard, until you get to the inner workings.
It's all based around WebDatabase and have the corresponding Store and Proxy extensions that translate your database to record models inside the store and back. All methods are supported (you write to the store and it writes to the database)
sorting and filtering is also on. Still working on the paging integration.
The application itself uses a php backend to proxy all the information to and from the IMAP/SMTP servers. Nothing is really kept on the server. There is no database or anything, just the source files.
More about it you can find at TouchMail

Very well done. Simple UI and good you used web storage. Hope you do well for the competition. And btw thanks for sharing it.
28 Oct 2010 5:20 PM #3
Thanks for the feedback
I don't know if anybody has actually tried to hook it up to account yet, but the app is pretty nice. It automatically recognizes contacts, it let's you add new ones from emails you've got. It syncs with the server, so whenever you delete a message, it get's deleted from the server as well and send messages get copies in the sent folder on the server.
I have lots of ideas for improvements, but that is what I got for these 3 weeks
I hope to finish most of it soon, so it can stay cached on the devices and be used offline (what it's actually mend to do)

Is it possible to download a version to test it?

Hi there, do you have plan to open source it, so we all can have peek

If you ride in dry and dusty conditions, a foam pre-filter kit is a great way to extend the life of your main filter, and more importantly your engine. Nothing protects your engine as well as an oiled foam UNI filter. Adding this pre-filter to your air intake intercepts sand, dust, silt, and dirt before it can even get to your main air filter.
An added bonus to this pre-filter is that it's completely washable and reusable. After a dusty ride, simply pull the filter, wash, oil, then re-install. The high quality foam material ensures the filter will last many rides.
The pre-filter simply installs in place of the stock snorkel on the Tiger 800 or 800XC. It is easily accessible by removing the seat. The filter fits both ABS and non-ABS models.

This paper presents an online simulation framework that can be used to support operational decisions within the context of Through-life Engineering Services. Acting as a closed-loop feedback control mechanism, the simulation model is physically coupled to the assets and will be triggered and automatically executed to assess a set of operational decisions related to maintenance scheduling, resource allocation, spare parts inventory etc. Experimental cases comparing the online simulation against the traditional approach will also be presented. The outcomes have demonstrated the prospects of the framework in enabling more effective/efficient operations of engineering services leading to high assets availability and reduced through-life costs.» Lire plus

Is it possible to turn on a custom feature atomically when you create a new site collection? I have a branding feature that I want to be turned on by default for each site collection made.
For now, SharePoint 2010 does not support event for site collection adding or added.So it is not possible to do it programmatically
Yes, You can plugin your feature to the site definition used for the site collection by "Feature Stapling".
You can define a feature at scope of Web application. It will automatically activate the stapled feature(which is your feature) within every site (in web application) that is based on the site definition you provide in <FeatureSiteTemplateAssociation> like below sample.
If you want to activate the feature for all kind of sites in web application, you can associate stapling a feature to global site definition(TemplateName=" GLOBAL") and blank site (TemplateName=" STS#1").
Change the Id to your feature Id in above sample.
The scope of the feature that does the stapling must be higher than the features being stapled. For example, a feature at the site collection scope can staple only features at site-level scope. So, you can fine tune the your feature scope accordingly
Yes, it's possible. The (probably) easiest way is to use feature stapling. Then you can say that all new instances of e.g. STS#0 (Team site), should activate this feature.
You can create a a Feature of Web Application Scope and deploy it on your Web Application. So whenever you will create a site collection in your web app, that feature will be activated on it.
You can also set the Automatic Activate property of the Feature to TRUE.

Revision as of 08:57, 20 February 2013
|Chin-Up Bar
Title text: Those few who escaped found the emergency cutoff box disabled. The stampede lasted two hours and reached the bottom three times.
Black Hat is blocking traffic on the longest escalator in the country, the escalator in the Wheaton station in Washington D.C.'s Washington Metro.
An escalator is a motorized stairway. Black Hat installs a chin-up bar at waist height. Chin-up bars are typically capable of holding up a 300 pound (130 kg) person without moving. Being at waist height makes it hard to duck under, and hard to hurdle. Either way, on a crowded escalator during a high traffic period, avoiding the bar will be extremely difficult. The first people would probably stumble backward to avoid it, which would collide them into the passengers behind them, creating a domino effect all the way down. Of course, as the escalator continues to move people forward, but the wave of falling people is moving backward, its apparent speed will be slower than it actually is.
That is the joke in the title text, that over two hours the wave can reach the bottom only three times, whereas if this were a simple staircase the event would only last once and be over as quickly as people can fall down.
- [Black Hat is standing on an escalator as it ascends. He is carrying a pole with what looks like a bracket on each end, resting on his shoulder. In front of him is Ponytail, and in front of her is a punk with spiked hair and pimples. Behind Black Hat is Cueball. Behind Cueball is a man wearing glasses with a goatee standing next to someone with short hair.]
- [The view closes on Black Hat and Cueball. In the background a girl can be seen standing on the descending escalator.]
- Cueball: This is a long escalator.
- Black Hat: 70 meters. Longest in the country.
- [In the background the girl from the last panel has now passed the group and a few other people can be seen descending.]
- Cueball: Why're you carrying a chin-up bar?
- Black Hat: Why aren't you wearing a hat?
- [The view opens up a bit more to show the two riders ahead, and the two behind.]
- Cueball: I'm not really a hat person.
- Black Hat: And I'm not really a Not-carrying-a-chin-up-bar person.
- [Close up on Cueball]
- [The view opens up to show the same people in the first panel. They're near the top of the escalator now and Ponytail is beginning to step off.]
- Cueball: Seriously, why did you bring it?
- Black Hat: How should I know? I'm not a psychologist.
- [As Black Hat steps off the escalator he turns and installs the chin-up bar such that it blocks people from leaving the escalator, about waist height. Cueball turns to observe what Black Hat is doing.]
- Twist
- Click click
- [They get onto the descending escalator. The man with glasses and a goatee and his companion are blocked from leaving the escalator by the chin-up bar.]
- [The next panel is large.]
- [The view shows an extended section of the escalator, the top right has become a pile of people all squished together and on top of each other. One person has grabbed another by the hair and is standing on a third person in an attempt to not fall. Someone is falling off the pile and another person is running down the escalator to avoid them. People closer to the bottom of the escalator are looking horrified at the scene ahead of them. In the background hat man and his companion are visible. Black Hat is looking toward the bottom of the escalator, not caring or noticing the chaos unfolding. Cueball looks back pensively.]
- It would appear that the goatee'd man behind Cueball has been seen before as the Psychologist from 435: Purity. It would also seem that the person he is with might be the Sociologist from that same comic.
- If it is the psychologist, he should have been able to diagnose why Black Hat was carrying a Chin-up bar.
add a comment! ⋅ add a topic (use sparingly)! ⋅ refresh comments!
I know the Wheaton Metro station and its escalator very well (I live about 5 miles from there). There are several issues with the comic.
- There isn't a convenient place that the panels showing diagonal motion (1-6 & 10) can be shown from. The entire escalator set is in a solid tube through the rock. I guess that it could be done from the *third* escalator.(See http://en.wikipedia.org/wiki/Wheaton_(WMATA_station) ) (This would be with (viewed from the bottom, the center going up, the left going down and the right either not moving or going up)
- There are emergency cut off boxes both at the top and the bottom of the escalators.
- There is a kiosk about 40 feet from the top of the escalator staffed by an employee next to the fare gates.
- In panel 9 there are two raised disks between the up and down escalators. While this is true in some of the other escalators, the ones for Wheaton are very close together and there is only one column of raised disks.Naraht (talk) 16:41, 28 February 2013 (UTC)
- What can we learn from this? - That not all of the facts in XKCD comics are right, and some are outright exaggerated (thank you Mr. Naraht). I personally learned that life will keep hurting me on purpose until I figure out how to help myself (Thank you Life and thank you Mr. XKCD for this lesson). - E-inspired (talk) 16:46, 28 February 2013 (UTC)
This is a comic. It's Fiction. It does not claim to be the "Wheaton Metro" escalator anyway - that was in the commentary. Relax. 184.108.40.206 19:16, 22 March 2013 (UTC)
- While I agree that Naraht needs to calm down (I used to live 1 mile from the Wheaton Metro, and would walk up it as fast as I could), you cannot say that the comic did not claim to be the "Wheaton Metro." Black Hat describes it as 70m long, and the longest in the country. There is only one escalator that fits that description, and it is in Wheaton, Maryland. It's like seeing them going up an elevator, never seeing what they are ascending, and having one of the people mention that they are going to the top of the tallest free-standing stone structure in the world, 555 feet, 5 1/8 inches. There is but one structure that fits that description: the Washington Monument. A description can make a claim without using the exact wording. 188.8.131.52 03:44, 7 August 2013 (UTC)
Grammatically, the last sentence should be "The people that actually made it to the bottom were unable to use the emergency shutdown because Black Hat had disabled it. ", (adding 'had' to 'disabled') using the past perfect for the last clause because it refers to an earlier time than the time of trying to use the emergency shutdown, even earlier than the events of the first panel. -CFitz 184.108.40.206 10:39, 12 November 2013 (UTC)
The title text does not say "those few who reached the bottom." It says "those few who escaped." Several people could have gotten around the chin-up bar or jumped the divider to get on the down-escalator.

In the new Android/iOS app/game/experiment called Curiosity, how long does it take for the cube to update? I did a ton of work in one section of the cube and I carved in my initials. Then I got on my wife's Android device, to see if I could see my work on another device. I couldn't find my stuff. In fact, it looks like an entirely different cube --- there was absolutely nothing in any area that looked remotely like what it looked like on my device. So I thought maybe it would take a while for my work to get updated. So we waited an entire day, and revisited the cube on both devices. Once again nothing looked similar at all. We zoomed into the exact same location, and waited for a few minutes in case it needed to catch up or something. Indeed, after a few minutes the cube DID refresh (bonus question: how long does the in-game refresh take to happen after you start the app?), but it was entirely different for both devices.
I already considered and checked to make sure that we were really looking at the same side of the cube, in the same location. We checked several times over the course of a couple of days, and the only conclusions I can come to are that either, A) the game is lying, and just randomly making it appear that the cube is being chipped away at by other people, or B) there is more than one cube.
What's the deal? I'm already aware that they have been having issues (coins being lost, etc.), but I have not seen anything regarding what I'm talking about.


text: I am developing an intranet site on a Raspberry Pi and am interested in incorporating Piwik into my code. My question, however, is how much overhead impact there will be with the pi's CPU/RAM? Does Piwik run as a constant and all the time analyzer in the background, or is data fed to it fairly passively until someone accesses Piwik from a browser, at which point would system resources be consumed in depth?

I replaced my graphics card but I'm not sure how to set things up on Ubuntu.
When the computer boots, it doesn't start GDM (I think that's what it's called). Instead, it asks me to log in the command line. If I try to do a
startx, it tells me there is no AMD device connected or something to that extent.
I originally installed the ATI drivers using the GUI. It said that I was using the limited drivers or something to that extent with a popup on the right of one of the taskbars, so I clicked there and updated it. I think it could also be reached by going to System > Administration > Restricted drivers or something close to that.
I tried installing the nivida drivers by doing a
sudo apt-get install nvidia-glx-185 and then doing
sudo modprobe nvidia and
sudo nvidia-xconfig as this guy says but that didn't work.
modprobe couldn't find anything related to Nvidia and
nvidia-xconfig wasn't an available command for me. Since I wasn't sure how to remove the ATI drivers I did that without messing with them. Not sure if that was a good idea.

IR Thermometers read surface temperatures. Can they accurately read the interior temperature of my oven through the glass panel? Or will it be reading the surface temperature of the glass rather than the interior?
It will measure the temperature of the glass itself, but not necessarily in an accurate way. Most glass is largely opaque to IR, but will radiate IR of it's own based on temperature.
The trick with IR thermometers is that they are guessing the temperature of an object by making an assumption about how much IR (Infrared Radiation) that object will radiate when it is a certain temperature. Cheaper IR thermometers have what is called "fixed emissivity", which means that they always assume that the object you are measuring is radiating 95% of the radiation that it would theoretically emit if it were a perfect black-body object. An emissivity of 95% (or 0.95) is a good start for most household objects - cloth, painted surfaces, etc.
Where it breaks down is with things like shiny metal, glass, liquids, etc. For those objects, the amount of radiation released at a given temperature is more or less than the expected 0.95. Shiny metal pans, for instance, can be as low as 0.2, meaning the displayed temperature will be much lower than the actual temperature.
You can use tables of emissivity values to correct your temperature reading, like here: http://www.tnp-instruments.com/sitebuildercontent/sitebuilderfiles/Infrared%20Thermometer%20and%20Emissivity.pdf (Note, for this table, use the 8-14 micron column).
That takes away most of the convenience of the thermometer, but it is a useful reference. The closer an object's emissivity is to 0.95, the more accurate your thermometer will be. You can improve accuracy by painting an area flat black, or even using a piece of masking tape stuck on the object to make a good "reading point". Fancier thermometers allow you to set the emissivity, and even fancier ones allow you to auto-calibrate with a contact-thermometer add-on.
To get back to the original question, glass has an emissivity of around 0.75-0.85, meaning the measured temperature will be a little lower than the actual temperature. Of course, even an accurate glass temperature doesn't tell you a lot about the actual oven temperature. My favorite surface for taking the measurement is my pizza stone, which is just about 0.95, perfect for accurate readings.
Sorry, you'll have to open the door. IR Thermometers will typically only read the "exposed area and not through glass."
To make use of your IR thermometer, be aware that "They will not measure polished surfaces accurately, or measure through glass, because glass can block infrared radiation. To measure such surfaces, stick a piece of flat finished adhesive tape to the shiny surface ... and point your thermometer at the tape. (Fluke)"

I was playing with my computer attempting to install Ubuntu 12.04.2 LTS i386, and I accidentally converted my C:\ with Windows on it to EXT4, and Windows hangs on boot. All of windows is still on the drive, along with the files, but I really want to use Windows again. All I need to know is how to convert back to NTFS without losing windows. Any help would be appreciated.
Despite what some other people are suggesting, formatting a partition generally doesn't erase all the data on it. However it doesn't exactly keep them either. It wipes the file table that records what files are stored on the partition and where. Generally the data for all the files will be there, but as you start using the partition it will get overwritten with new files. You are unlikely to be able to go back to NTFS and have all the files, directory structure etc exactly as it was before. You are unlikely to be able to get Windows to boot properly without reinstalling it. You should be able to recover most of the files using a file recovery tool such as TestDisk or PhotoRec, but there is no garauntee.
I'm sorry to say it, but I believe you formatted your C: to EXT4, which erases all data on it. Like psusi said, there is no way to "convert" NTFS to EXT4 - you must be getting mixed up with formatting. Again, if this is true, all data has been lost. Be more careful next time; it even warns you!
CITATION: Convert filesystem NTFS -> EXT4?
Use TestDisk (http://www.cgsecurity.org/wiki/TestDisk) to undelete the files. Save the recovered files to an external drive. Then, reformat EXT4 to NTFS. Lastly, move the files from the external drive to the new NTFS filesystem.

I heard over the weekend that Mary Tamm, Romana I from the original "Doctor Who", had recently passed away. Sad news. Details here: http://www.mirror.co.uk/news/uk-news/mary-tamm-dead-tom-baker-1169800.
While I'm at it, R.I.P. for the recently deceased Sherman Hemsley (great work as George Jefferson) and Chad Everett (who, along with James Brolin, was pretty much the proto-George Clooney for TV medical dramas when I was a kid).

"It's a huge party, and we never expected it to be that way," said brewery co-owner Joe Rowland.
Started last year as a way to incorporate the ideals of the brewery with the ambition and diverse character of people hiking the entire A.T., the releases (three a year) have garnered quite a following of beer connoisseurs and nature wanderers. The first release is timed to coincide with the waves of thru-hikers — a hundred or more a day at their peak — passing through the region in late March en route from Georgia to Maine on the footpath.
The events focus on the idea of "trail magic" — a random act of kindness that occurs on the trail, whether it's providing food to a hungry thru-hiker or inviting them into your home for a shower and real bed.
"That whole concept of doing something totally random, an act of kindness we can tie to the A.T., just fit us," Rowland said. "So, we came up with the series, which coincides with the launch time, midway point and end of hike."
The vision for the releases came from Rowland and others at the brewery occasionally setting up shop on the trail. They would grill out for the day and provide anyone passing by with a hamburger or drink. It became something that really inspired Rowland and opened his eyes to the vastness and wide array of humanity moving along the sacred route.
"People who go out and hike this trail, it's just amazing to see the variety out there and why they're doing it," he said.
With the trek averaging around six months to complete, the brewery kicks off the first release in late March, which is typically when hikers start to trickle through the area. The other two are scheduled to take place on June 7-8 and Oct. 11-12.
Rowland said there are a handful of requirements for the beer, including that it has to be high gravity (stronger alcohol content by volume) and must contain some sort of local ingredients. The benefits of a high gravity concoction is that is ages better, meaning a year from now it will taste as fresh as it did the day it was tapped.
This first release of 2013 will be a Russian Imperial Stout. It was made with local sorghum (the ingredient used in molasses) and wildflower honey, and has been aging in used Maker's Mark bourbon barrels.
"We don't replicate any styles that we make [for the releases]" he said. "The possibilities are endless when you're making a product like that."
Of the revenue brought in, Nantahala has partnered up with the Friends of the Smokies and the A.T. Conservancy, two groups that work to protect and maintain the trail — whether it's the trail bed itself, the landscape it passes through or the intangible trail experience.
One of the programs they support are the "ridge runners," a vital team that spends days at a time traversing legs of the trail aiding thru-hikers. While ridge runners are found the length of the trail, they are all the more critical in the rugged and secluded section running through the Great Smoky Mountains National Park, where the distance between trailheads or nearby towns make hopping off to get help impossible. Ridge runners not only help educate thru-hikers but also provide them with any weather reports, supplies, medical attention or miscellaneous needs they may have while in our backyard.
"This is one of the most popular sections of the trail," Rowland said. "And these ridge runners make sure hikers are good to go. It can be extremely remote out there, and you probably won't have contact with anybody else except other hikers."
Trail magic: the real stuff
But, the cherry on top is the biggest surprise of the weekend. As soon as the event begins, the brewery sends a vehicle down to the Nantahala Outdoor Center where the A.T. passes through. With the help of friends who work at the NOC, a few people are randomly selected off the trail and invited to partake in the festivities up in Bryson City.
"Right now, there are people on the trail that have no idea they will be selected," Rowland chuckled. "They're going to be picked off the trail, have a cabin setup, the whole nine yards. It's pretty cool."
These folks are chosen based on their humility and intent for doing the trail. Once at the brewery, they are crowned the kings and queens of the release party. From there, they are whisked away to the nearby Watershed Cabins, where they can rest and relax in some of the finest accommodations around — free of charge.
"we aim for more of an older crowd, so that they won't damage such a nice place," Rowland said. "And we want to choose people that are serious about doing the trail."
In 2012, the brewery selected three hikers with stories as unique and astounding as the quest itself. Two were a couple that had met on the trail the previous year. She was a Type-1 diabetic (one of the first with the syndrome to complete the trail). He was a veteran and Purple Heart recipient who had lost his wife and daughter in a plane crash. They fell in love on their initial trek and decided to celebrate their engagement by doing the journey again.
The third person picked up was a renowned female hiker named Yogi, who rose to wilderness fame with her cherished trail guides she wrote about the Pacific Coast Trail.
And yet, for Rowland all of these people, places and things are part of the rich philosophy of why he and his comrades decided to set deep roots in Western North Carolina and create fine craft beer.
"If you make a good product, people will come and find it," he said. "Bryson City is one of the last little outposts where you can be this close to a giant wilderness area and still be able to go out there and explore it. You can't get that anywhere else."
Want to go?
The "Trail Magic Ale No. 4 Release" will take place at 6 p.m. on March 22 and noon on March 23 at the Nantahala Brewing Company in Bryson City. The festivities include music and the brewery's newest creation, a Russian Imperial Stout. Music acts include Liz & AJ Nance and The Freight Hoppers, with other groups to be announced. Attendees are allowed to bring their own food (grills are provided outside). As well, if you have a limited or rare homebrew/beer to offer for sampling at the brewery, feel free to bring it. There is no cover charge for the event. All patrons must be 21 years or older.

Just Another Genome Hacker,
Sadly, my most voted-up answer on Stackoverflow (312 votes) belonged to a question that later got deleted. The question came from a girl that asked for something cute that she could put on the icing of a birthday cake for her programmer boyfriend.
I suggested that, if her boyfriend is somewhat mathematically inclined, she write the following:
sin(t) √|cos(t)|
r = __________________ - 2 sin(t) + 2
sin(t) + 7/5
If he doesn't get it at first, she could tease him with saying that it is obvious that he should take the polar plot of it. If he still doesn't get it, she should tell him to enter it in WolframAlpha, that should yield the result:
