Khronos Releases OpenCL 1.2 Specification
New features in OpenCL 1.2 include seamless sharing of media and surfaces with DirectX® 9 and 11, enhanced image support, custom devices and kernels, device partitioning and separate compilation and linking of objects.
Didn't read all of it yet, but one thing i can answer right now:

The modules you mentioned have been superceded by better ones like XML::Twig, Config::INI::Reader/Writer and HTML::Treebuilder (and likely a lot more that i don't recall presently). Also, those bugs you point at are of medium amount, and not exactly crippling. Similar libraries in other languages likely have similar bugs, but they're less known because there's no unified bug tracker.

The problem with doing that is it would require very comprehensive reviews or for customers to very thoroughly try out all products before purchase.

For example if a new product is launched on the market and it appears to be cheap but you know that it has a Fast Quad Core CPU and decent video hardware , you already know in a relatively small amount of text that it will be good for video editing , gaming and various other tasks.

If it only has a 300Mhz CPU you already know that it will not be good for any of these tasks and you can confidently avoid it.

As another example I remember years ago seeing computer adverts which would attempt to simplying their specs with bylines such as "Family Computer" , "Small business computer" , "Games Computer" etc. What if you want a PC for use by all the family for homework/internet etc but the oldest child happens to be an avid WoW/COD Player and Dad plans to use it to prepare accounts for his small retail business?
For 1 guy coding alone that is a good return. $2000 per month doing something you enjoy and that is changing peoples lives is great.

Coffee Tables
One thing I had drummed into me in my UK ICT education (admittedly 15 years ago and it wasn't called ICT then) was that we were aiming at fulfilling client desires; that we shouldn't just go off and produce something cool, if it wasn't of use to the described and defined end user (who we had a great amount of freedom to select) and we couldn't objectively justify our development approach, it wasn't good enough.

Now, I can't say I object to a marking scheme that requires students to learn to develop what is useful and efficient rather than just what is cool...
I hope governments around the world are reading this and taking note. When you make it hard for your citizens to set up shop in your country, they are going to go somewhere else where it is easier. And all of the jobs that they would create, and money that they would pump into the local economy goes with them. It is similar to what happened to the movie industry in Hollywood. When other states and countries started offering tax breaks and streamlined permit processing, big productions moved out of California.

It's very unreasonable since they deposited the money and had zero transactions. Dwolla got the money from their bank account, and my parents wanted to send it back to the same account.

It's even more unreasonable since they gave no notice that there was a hold on the withdrawal.

Very true. I think that it is because of the form factor (small screen, full touch) that design is essential. Fortunately there are some great designers out there for programmers to hire. I've had my most success with iOS apps where I hired a designer (I'm a programmer).

I don't see any source that would lead me to believe that "Most" of the Dwalla transactions come from BitCoin, anywhere in your 3 links.

"A portion of" or "part of" does not mean "most of", any way you look at it. So, do you have any concrete sources?
It’s not so hard, really. There are a very limited number of use cases, a limited number of tradeoffs. A long list of specs is much worse than just writing “This machine is great if you need a lot of power for video editing and rendering and other creative tasks. It is, however, correspondingly noisy, hot and big, not a very good fit for mobile use or for anyone who needs a quiet computer.” That’s so much more helpful. Specs are code in comparison.

Specs confuse, specs frighten, specs suck. They force consumers to figure out the tradeoffs that stand behind them. That’s too much work.

In Europe it works like this: If you want to receive money, you give the sender your bank account number. The sender can then transfer money to you using his bank's website or mobile phone application. There is no risk involved, because knowing somebody's bank account number only enables you to send them money -- but not to withdraw money. Transactions are usually free, but take one to three work days to complete.
If you are going to outsource you best have a lot of money. Remember you will go through several iterations or smaller changes before you get it right. That is extremely costly to you. You would be better off taking 3-6 months learning. This way, if your product fails (like the other 95% of all businesses), you won't come out empty handed.
I wish him well on his endeavor because I'm not a fan of CC fees, but from a consumer standpoint, I don't see any benefits. CCs provide (i) a line of credit, (ii) fraud protection, and (iii) rewards/bonuses. All of these can be incredibly valuable, particularly (ii) - you never appreciate the no-liability fraud protection of a CC until you discover how difficult it is to deal with situations in which your bank account is affected.

If credit cards were not already the dominant electronic payment mechanism (i.e. VISA/MC were just starting like Dwolla is), Dwolla could possibly win out because businesses could refuse CC's. Not going to happen now, at least with regards to business-to-consumers. And I don't think most B2B transactions were conducted through CC's anyways.

They seem to be doing okay now, but I don't see any secret sauce that's going to make them anything more than a fringe player in the payments industry.
Ask HN: Do video games influence (good or bad) behavior?
NULL means "don't know" or "no value." Whether a column should allow NULLs at all depends on data and application.

As for storage requirements, it depends on the storage engine. For MyISAM tables NULLs don't take up any more space. InnoDB tables there may be some small savings in space. Each storage engine implements NULLable columns and NULL values differently. Worrying about the space occupied by a NULL is a micro-optimization unlikely to affect real disk space used or database performance.
Joe Fernandez: The Vision Behind Klout
You can, I just confirmed by bank account with Dwolla this morning.

One of the guys asking Dwolla questions on Twitter was a 4th generation jeweler, who regularly has $10k and up transactions. He was very eager to learn about the merchant APIs. He could probably save $500-$900 on a $30k ring if the transaction was made with their service. There are a million examples like that out there.

> I think in general you are going to find depressants will act like depressants, and stimulants will act as stimulants.

I believe this to be true, although, I am talking about those who suffer with ADHD or other dopamine-related disorder.

> It is a stimulant for all people when consumed in the right amount, though it also depends on other factors. Some days alcohol will make me stay up all night, some days it will put me to sleep in 15 minutes.

My theory is, a substance is a stimulant or depressant relative to your dopamine (or brain wave activity). Too much dopamine reception? Depressant. Too little dopamine reception? Stimulant. It has been reported that average people taking methylphenidate (ADHD medication) experience drowsiness (too much dopamine reception) as oppose to those who have dopamine receptor deficiencies, find the drug as a stimulant (too little dopamine reception).

Also, dopamine levels often vary throughout a day for most people, so your perspective would hold true with regard to this theory.
Yes, indeed, the gene may be detrimental under certain conditions to the individual (e.g: two copies of same gene), if it helps the individual in the average case.

There are many nuances that my statements in previous comments gloss over and which make them incorrect.

My point is that "societal selection" of genes is rare and virtually completely insignificant.
If someone needs a bone marrow transplant, their immune system is severely compromised (effectively eliminated). If they're given marrow from an infected donor, they'd have no way to fight off the resulting infection. It would be a death sentence.

On the other hand, many people who need a marrow transplant have some flexibility as to when they can get the donation. This is why the guidelines are so strict: the risk/reward ratio is balanced in favor of caution.
Maybe. Though Apple gives you a lot of tools to help you make good (though simple) looking applications. UIKit is pretty detailed.

Here is my simple design advice if you don't know how to design:

* Use the provided UI elements, they look great.

* Choose a primary color and an accent color, don't get carried away.

* Make sure everything lines up. Choose a number (10 pts) and align everything off of that. Aligning your UI elements will go a very long ways to make everything look good.

* If you have paragraphs of text set the line height to around 1.5 (depending on the font).

* The only thing provided by Apple that is Ugly is the UIButtons. Draw a simple, clean button or ask someone to make one for you.

If you follow these simple ideas you can make a pretty good looking application without knowing how to design.

Exactly; it is by far the most common p2p money transfer mechanism here in Italy too. I would never have thought that something like this could cost 25$ per operation in the US..
Even on my BF3 gaming PC, the UI feels slugish and lags on most clicks. In addition, it feels like the heavy-js sites are much more error prone than simple, hard-to-fail get+get+get sites. Battlelog is often not in sync with the real state of the server and your computer. Only page reloads can help in those situations.
I believe that you are wrong.

My understanding is that if a California resident signs up for a service with a company in Iowa that has no California presence, that becomes interstate commerce. According to the Constitution and case law dating back to the 1800s (largely established by mail order companies), California does not have the right to regulate interstate commerce. Even when one end of that transaction is in California.

That is, in fact, at the heart of the whole sales tax issue with Amazon that has been in the news. By California state law, sales tax is owed, but California can't regulate what Amazon, an out of state company, does. Only Congress has that authority. (It looks like they may do it as well.)

I am not a lawyer, and could be wrong. If you want actual legal advice, you need to consult a lawyer. But this is my understanding.
Low cost medical treatment
Thanks! I thought the concept of a temporary unfollow that was 100% client-side was interesting. The best analogy I could come up with for that was a "penalty box" ... again, thanks for giving it a try, very much appreciate it.
Interesting thought. I've seen IOUs between developers and designers go bad sometimes though. Different people quantify things differently. I gave a dev friend three hours of tutorial on photoshop, and later he complained about me asking him for the time back, even though that was the whole point – so I could learn some programming. Then it became an issue of "tracking hours too closely" and we never really connected again.

I'm not saying it can't work, but it does get hairy with "social debt" and how different people interpret that. "My time as a developer is worth $150 an hour, and yours is worth $75 an hour, so the time I put in is worth twice yours." I heard one dev tell a designer that once.

Why Java isnt for startups
I made an app that puts a feedback form on a website and emails the developer with user feedback. I know there are more sophisticated feedback management tools out there, but I wanted something simple.

You can see it at http://threecents.elevenbasetwo.com/signup/

Appropriately, feedback would would be great.
Accessibility cuts both ways, though. Choosing to prioritize the HTML-only version decreases accessibility to people who have limited bandwidth or download speeds.
Java scales. You can be slow or fast in any language.

I'm a bit confused, you have experience with Java, or you don't?
> yes, but the point is if the utility provided by these "dists" would be mostly useless for other languages, then it's hardly honest to use said feature to promote CPAN (and therefore perl) against other languages.

Jeeze, you're barely making any sense. I have to wonder if you're trolling here. My point was about the utility of the ecosystem, which is useful for any language. The dists i mentioned are just examples of distributions you could find on CPAN other than Moose which all receive the same treatment.

> I suspect most people install CPAN modules through the command prompt (or via their distro's package manager), rather than digging through a website.

The installation is done via command line, but it is always preceded by research on the websites. Would you exclusively buy movies by title alone without looking at reviews?

> I also note that Python tends to adopt the best packages into the standard library...

Perl core developers do include useful things as well, but they are fairly strict about which ones, since they prefer to leave them on CPAN so they can be developed and released at a faster pace than the core. And in fact, the core is increasingly being viewed merely as a tool to access CPAN.
it's spectacularly unstable for comparisons between cohorts though, most notably in the case of the Flynn effect. I find it highly unconvincing the average person in the 1930s had the same fundamental level of intelligence as those people scoring 80 on the same tests today.
The thing is that the Console companies control the supply of games so that only games that run fast (60fps+) are released. Basically you can't release a game that runs slow, so it's not an issue.

BluRay is that same, it's a standard and disc should work on all players.

Computers are not the same because the supply of software is not controlled, for example "Crysis" was released when it didn't work on most machines. In fact many machines were not even to fit to run the OS they came with, Vista, when they had 1GB or less of RAM - Microsoft does not stop even that.

Rate my startup: BusyFlow - making web apps work together
In my company (http://nous.lt) we are using tons of web-apps. They are awesome, but they do not play well together. There is no way to see the whole project status (new files, tasks, events, discussions etc.) or, for example, easily discuss a Dropbox file and then create a Pivotal Tracker task out of it.

We wanted to create something that saves time by letting us interact with all apps from one place and allows moving data between those apps. So we started building a workspace that integrates web-based productivity apps.

If you think this is interesting - give it a shot and tell me what you think!

Ruby even uses some predefined globals (eg $_) that are pretty much straight out of Perl.

They exist, and while I'm a fan of $: over $LOAD_PATH I don't think I've even seen $_ used in the wild.
Besides all the historical reasons cited, there's a simple reason: economics. The bulk of enterprise software are CRUD apps that maybe chat with an ESB or whatever; the quality is mediocre/ok, and whoever pays the bills just want to get the project done ASAP. The pool of Java devs is HUGE, it's quite easy to lose a Java dev and get him replaced the day after. The risk of using Java is very low from a management perspective; if you replace Java with Ruby/Scala/Python/etc the perceived risk would be much higher.

Besides, most big enterprises are already paying IBM/Oracle/Jboss/etc for Websphere/MQ/ or whatever App Server and support; it makes sense to use it anyway.

I would say it's mainly inertian and (perceived) risk management. BTW, I believe the Java camp got alot of things right, but that's another story.
What it gets you is the ability to give it to a household with a TV, and they can have a computer to play with cheaply.

If you're doing it right then your credit card account should be earning you the approximate equivalent of 1% cash back via rewards points or another mechanism. For my personal card I use Chase Sapphire (the one without the yearly fee), which gives 2x points for all dining purchases. Always confuses me when I see people using cash or debit cards. At my current rate of spending I could get a free iPad and a few other goodies every year by doing nothing more than not bothering to carry cash. In fact, merchants have to increase their prices slightly to account for the transaction fees, so anyone using cash is actually (in a small way) paying for my rewards.
Dude, give them some credit for moving $1M per day without even integrating with POS.

Yes. The fraud protection and line of credit are valuable to people but why is that linked to the processing fee and network? Those features are provided by the bank which only provide them irrespective of the network your purchases are processed on. That is the key.

The main advantage with a card is you can pay with it anywhere in the world. That kind of scale takes a lot of time to achieve and that is the reason the whole ecosystem is milking users.
Yeah, that was me. That Reddit thread was a lot of fun.
I think that "the reason" will vary from person to person. For me I prefer my credit card to debit because of consumer protections and chargeback ability; but I definitely know a lot of people that use their credit card as an actual line of credit.
