Thanks a lot, especially for the names of the books. After reading yours and other advice in this thread I am convinced that the way to get up to speed quickly would be to start with harder problems and backtrack as needed. Do you have any recommendations on books on analysis, the one I have with me is Walter Rudin.
Outside of the preprocessor, the char type is a one-byte integer (whether it's signed or not is implementation-defined).
All the discussion aside, there is so much wrong with it:

First of all, why does the function even accept strings? There should be some eception happening.
Second, why does it return 0, i could understand NULL but not 0 (for a function that is supposed to handle numbers, having it return a number in the invalid case, what is that?)
If it requires specific versions of PHP, I would hope that doesn't include a self-patched build that deliberately masks erroneous input data by treating NULL as 0

The moment you run a patched build, you're IMHO not running the officially sanctioned version any more.

I have to agree with the bug submitter in concept, if not in attitude. PHP is a dynamically typed language. As such, methods should expect surprises about the types of data received. Seriously, I've had PHP treat the same input as a string one time, an interface another, it's like it uses whatever is convenient at the time. If you neeeeed that data to be an int, cast it as an int, don't punish the user because type system chose a different type this time.

Additionally, and more to the point, in PHP 0 == "" == null == false, so it shouldn't be unreasonable to expect them to be treated as equivalent. It's also a nice thing when a method can always be trusted to return the same type, or these types of issues can end up cascading.

In any case, 'should' and 'nice' things are hard to rely on in PHP, that's why you should always have the docs open and read everything when writing PHP, making even basic assumptions about a method being well behaved will likely screw you over. :)
As the other replies have said, it boils down to bid rigging. What's interesting about it is the sheer scale. It apparently has been going on for at least 10 years, affects every state in the US and the banks have likely scimmed billions of dollars from it. What's particularly galling is that the entities they have stolen this money from are schools, hospitals, ports etc. Basically, another example of the already rich brazenly lining their pockets yet further with misappropriated public money. All the time hiding behind the supposed "complexity" of what they do and showing apparently no shame or remorse.
It sounds like you have no idea what an operating system is. Or, you're being unusually abstract.

Excellent, this is great stuff. I wish they had released a separate HTML5 Game Engine. At a glance, it looks like everything is tied pretty closely to the game itself. I've been looking at engines like Isogenic and Construct 2, but here you have a large HTML5 game larger than most had been able to demonstrate. Plus, its open source, where the previously mentioned engines are closed source and require a license purchase, although Construct 2 has pretty good documentation on how to make games. I really like what Wooga did with this.
> BUT the detector built its own categories(!).

It's not revolutionary. Clustering algorithms and neural nets are plenty.

Really, what differentiates this network is its scale.
I have observed myself that men tend to hate purple as a UI background color, while women like it. I have not seen that many high-quality sites with a deep purple backbround, but when I did, the designer was female. These numbers got something.
I think that these perceptions can be influenced.

For example, if Ferrari runs ads with only its yellow models for the next 10 years, more people might start associating Yellow with Speed, instead of an overwhelming vote for red
Or you put it in as a cheap link-bait tactic.
>Well, any school obviously helps you learn if you don't have a mentor or otherwise to help you sieve through the information.

I don't see how that's obvious at all.

I mean, I have a reasonable understanding of the creation side of business, and I can do straightforward sales; That side of things is easy enough to learn via trial and error.

Now, obviously, that's not /all/ there is to business, and maybe b-school teaches you about the bits I don't understand. But from a pure "you shall know him by his fruits" perspective, antidotialy, people with MBAs tend to be less successful (at sustainably growing the business... not at getting paid) than people without.

But yeah. as a small business that gives customers products or services in exchange for money? the most valuable thing you can learn is something about the product or the process that creates the product. The most valuable thing a small company has is the owner's labour. I mean, even with the ridiculous $150K/year salary numbers I hear friends throwing around these days... if I was working for someone else? I would have quit yesterday. (well, I would have gotten another job first, but... that has never been difficult for me.)
If it once was "credible" but no longer is, perhaps a more appropriate term is "uncredible" or "decredible".

Of course, that woudl imply that the act of removing credibility from something would be "decrediblizaiton" or "decredencing".

I'm in San Luis Obispo: 3 hours from LA, 3 hours from San Jose and 4 from San Francisco (6 if traffic is bad).

It's sunny, it's warm, we have nice beaches, good people, the pace is great. It is (literally) the happiest place in America (look it up). My only complaints are my allergies (really bad here compared to elsewhere) and it lacks in the culture/diversity departments.

I'm a bootstrapped founder so I can work from anywhere.

I think your fear is the opposite of reality. Medium sized cities need developers. I basically have to hire remote freelancers. We have tech companies here in SLO (Mind Body, Level, iFixit, etc) and many have standing open positions because we can't find local people (all the Cal Poly grads leave). Same goes for Santa Barbara.

You may not command an SV salary here but the cost of living is lower (not a lot) and freelancing on the side is always an option.

All that to say, you can definitely make it work.
I've taken it upon myself to learn coding and at times, I find myself completely hating it. I too view it as a "means to an end", allowing me to produce MVP without needing to consult with "professional" programmers paying them to create a beta product in which I will and can create. My goal as an entrepreneur is to be a triple threat: Marketing, Bus. Dev. & Product Development. I believe whether your in the tech, bio-medical or renewable energy spaces; you are supposed to be able to create a MVP even if it is crap; especially if you call yourself an entrepreneur.

The blog post is from an American blog, so noting that specific concept of freedom of speech from an American point of view is perfectly fine in this case. And in the American concept, freedom of speech is a constitutional concept regulating what the government can do to individuals.

But the difference is that you can show it 1 billion unclassified images, then show it 1000 images you know to be faces, analyzing how its neurons respond to the known inputs to use it to classify the rest of the images.

Strictly speaking, you do need to have some labeled data at the end in order to determine how the neural net views faces, but I think that obscures what's notable about this system.

The amount of human participation involved in training is potentially six or more orders of magnitude less. That's a breakthrough, and a change in kind, not just degree.
Wait, so it's the voters who are clamoring for the use of open auctions to determine what bank to invest public funds with? Um, no. As for "[hiding] what they're doing", what do you mean? The article mentions nothing about the municipalities hiding things from the public. If you're referring to the closed auctions, that's just a way of selling something that benefits the seller. It's not "closed" in any other sense.

So what you're saying is that, because a municipality is a public entity, it shouldn't be allowed to invest funds in a manner that would be perfectly acceptable for a private entity not because the entity's constituents disapprove, but because the banks don't like it? That's absurd. If buyers shouldn't be allowed to dictate the negotiation tactics of private sellers, they shouldn't be allowed to dictate the negotiation tactics of public sellers either. You seem to be conflating (or attempting to conflate?) the banks with the municipality's constituents. It's true that a municipality must answer to its constituents, but it doesn't have to answer to any private bank that feels like whining.
I agree - the main problem is that basically no one has an idea what the day-to-day life of a scientist looks like. The outreach programs of Fermilab et.al. for school children are nice, but I'd be very interested to hear how to get in touch with working professionals to show them that

(a) scientists are not dangerous and
(b) there is work done in the ivory towers that might have a positive impact in their field
I know a ton of people who were "working poor" either just post-WWII or as immigrants, who nonetheless have managed to acquire some pretty good sums of wealth. Most of them don't go as far as being "a generation ahead", but their hard work and sacrifices put their kids and grandkids in position to be successful without going through the sorts of financial dire straits that others treat as normal.

As far as I understood, the release notes were not very explicit or complete (the list of impacted functions were missing) on this issue.

It is not enough to ask people to read the release notes, these release notes should be complete and usable.

I'm with the side of people saying you shouldn't have to apologize. That's like saying you apologize for not finding Tim Cook's personal email when iCloud is down and they ignore your calls, support tickets, emails, inquires at the genius bar, posts on their support forum, etc.

It's THEIR responsibility as representatives (and owner) of THEIR company to make themselves available via the information THEY provided, on the site you signed up for THEIR services.

They deserve the zingy blogpost and don't deserve your apology.

This is bad business and frankly I would stay far away from them despite your newfound guilt.

> Perhaps most amazing is many people's apparent assumption that banks would never engage in this kind of behavior.

I was sort-of witness to a shouting match between a well educated son and his hard-working working-class rest of the family over the fact that banks give out let's say ~ten times as much as they actually have. They called him stupid, outrageous and how could any company possibly do this and they can certainly not run their small wood-shops and small companies like that so how should a bank be able to do that? Mind you, these are average good natured law abiding folks, the kind that certainly is the majority of the population.

This goes to show that there certainly is a vast amount of blind trust in banks in the average population; looks like acting all serious-business and putting on a suit AND being able to control or at least have an important stake in a lot of major aspects of working-class citizens' lives (tight budgets, making ends meet) makes for a powerful combination.

Angry Birds for the Web was developed for HTML5 and it works reasonably well on desktops and cross-browser (runs on Chrome, Firefox, and IE9+) It runs offline via HTML5 AppCache, via Chrome app, or online.

Maybe your article should be titled "Writing games in HTML5 for Mobile Devices is not ready". because I don't think the same reasoning applies to the desktop.

You won't achieve 100% reach, as you will fail on some combination of hardware, but perfect is the enemy of the good here.

Also, I think there is a little bit of arrogance in the two articles Wooga posted. They claim they are one of the most technologically sophisticated HTML5 games, but that seems dubious. Angry Birds, Field Runners, Bejeweled, Sonar, and Cut The Rope, are just a few of many of the games out there are push the limits of HTML5 performance, and are much smoother than Wooga's offering and do more onscreen. I don't want to bash them, I just want to make the point that if they are having performance issues, it's not because they are pushing the limits of what the browser is capable of.

The real lesson is that mobile browser performance sucks, especially Canvas operations. If and when Mobile Safari and Chrome for Android get WebGL, mobile HTML5 games might be more plausible. Javascript performance on mobile has been doubling roughly every generation. The newest WebKit implementations like iOS6 support the Web Audio spec which addresses low latency sound, and File System APIs for local storage. In another generation, it may be more viable.

Have a look at Quake ported to HTML5 done in 2010 by me and a few others: http://www.youtube.com/watch?v=fyfu4OwjUEI&feature=playe...

Back then, it ran at 45-60fps. Today, it runs at 200+fps on Chrome on the same machine.

There are options for multiplatform development. Angry Birds was done with PlayN, in which you write you game in Java, and we compile it to JS (with GWT targeting CSS3+DOM, Canvas, or WebGL), Android (run direct on dalvik with OpenGLES), Flash (via GWT->ActionScript compiler), and IOS (via translation to CLR + Monotouch ahead of time compiler)

hAXe is another similar platform. Write code in ActionScript3-like typed-Javascript, compile to JS/SWF/C++/Objective-C/etc.
This is a tough one, some of the second string accelerators could be failing because of the applications they are getting.

It becomes and chicken and egg problem, to get good mentors and attract investors they need to get good founders involved. To attract the good founders to an extent you are going to need good mentors and access to a strong investor network that the founders benefit from accessing in conjunction with the accelerator. Or alternatively a far better equity deal.

It's really uncool to blame your poor planning on other people. This is a business not a frat party you forgot to text somebody about. You're the owner of a company that is taking other peoples money for a service. You dont get to say "Sorry guys, I was moving". I mean, are you serious? That's your excuse. You could have easily delegated some time or had an employee handle support and offset your move dates in order to offer seamless support and not put peoples trust and their own customers relationships on the line. If i was your customer I would immediately jump ship.

Also: 3 weeks of no response is far from "quickly" becoming snipe. I could understand if that mans blog post was after 3 days, but 3 weeks? Come on. You guys fucked up.
The only originality in this work is the processing power used. The principle in it self is not original.

For a possible resemblance with the real cortical neural network working principle and face or object recognition, this is just a farce.

Regarding getting closer to the presumed singularity, this is like saying that cutting flint is close to making diamonds.

The authors didn't claim that, but the abusive use of "neural network" for such kinds of applications is just doing that. It is a dishonest abuse of people who can't make the difference.

The true problem is that significant quality work toward modeling real cortical neural network is drown in the sea of such faker crap.
No, not good enough. Each bank chooses different exchange rates. Using a converter gives you a spot price from one institution. There's no telling what the customer will actually be billed. Indeed there's no certainty that the transaction will even be journalled that day. Moreover, they'll be slugged for an "overseas transaction fee". Finally, it means you're unable to use any kind of collateral that quotes a price, because you can't guarantee it.

It's a marketing disaster, in fact, and would look completely amateurish.

The reason we wanted to have the code itself in space is because there ARE things people can control on the sat (supervised by us): you can control the cameras, command the attitude control, and activate the antenna. We also thought it would be more rewarding for students who want to use the satellite to gain real experience in coding on real hardware.

The you're right about the commercial GPS, it wont return location data above a certain altitude. We want to use the commercial GPS for other experiments (it will still have some functions that work). We've also included a second space-rated GPS in the bus itself for the location data.

To help us bring down the integration/testing time, we've teamed up with the manufacturer of the components of the satellite, they will be using their facilities and engineers to make sure we deliver by 2013 launch date.

Let me know if there is anything I can address about the design!

Cheers,
Joel
