well, it loads quickly because contents are provided according to your user agent and black magic with js pinging your nearest best CDN possible near you and with optimal bandwidth, and then, according to a complex choice in a matrix of supported codec(your SW)/compression(CPU)/bandwidth(the net) a video is chosen through painful trial and errors, where every choices in the matrix (growing at the power of 3 and more) is almost made by humans.

The "progress" we could benefits from these new techniques is so complicated and resource greedy and provoking a lock in of customers that I don't think it far outweigh the cost of the poor compression/control of the gif.

in the thread the guy explains that he works @nvidia, but not the GPU desktop BU but for tegra that seems a 'burnt on the chip' of the card minus the pci bus and one clock (memory clock maybe?) (according to what I understand of the source). And he seems to say this division (tegra) does not reflect nvidia global policy. I may have made quite some mistakes in precision, but globally I think that is the idea: this is not nvidia doing

well the fiducial (fiduceo I believe in latin) which people believe to have value (hash of hash of ...) requires a lot of computation thus electricity thus resources.

Whatever brainwashed geeks thinks computer industry is already using a lot of it, I am pretty confident people would be the surprised at the Total (Real) Cost of Ownership of a bitcoin, and I am absolutely not convinced it beats real money on the long run.

And, subsidiary question: will this money scale (in cost of energy)?

It is not as if I was not aware that Pypi module distribution (I am a python programmer) is unsecured and that python is lucky enough to have no scrutiny of the community.

Discussion on Pypi (catalog-sig) are pretty much advancing in the direction of a kombinat (something to complicated to be even appliable).

But I can make sarcasm because nobody will check my claims and will consideer good will and awareness as a good direction.

To be honest, the computer industry is like lemmings building a cliff of uselessly complicated stuff from which we will fall.

May the computer industry please quietly wait my retirement before crumbling down.

So basically he rediscovered poorly Bauhaus works about design and some 400 years old knowledge about typography, and he missed the last 10 years in computer industry (when screen size changed from 640x480 to 1920x1080 and industry adapted). He missed the palo alto parc works (let's say the creator of all modern computer interface) stating scientifically (biomechanic stuff) touch screens based interface will never ever works. And of course his slides contradicts what he says (blue letters on blue background vs the advice of high contrast).

I love this guy, so bold that people may believe him.

BTW, doesn't it strikes you that his domain name is «prophets.be» his quotes uses a lot of words like mantra, and theologic crap, and that a theologic website is an example?

Doesn't the word illuminated come to mind?

The cool stuff about religious people is that they can make you believe impossible stuff are possible. It is almost has fun eating shrooms.

Thanks, I always wondered how VLC was so efficient at translating pictures in colored ASCII art.

I studied physics, and I learnt actual programming and assembly language: I actually did this in the real world!

What do you learn in Computer Science then?!

Gibbering useless concepts that makes you non-sensical experts in the field of not delivering your software neither in time, nor in the frame of the specification? Or just

There are so many security issues being unveiled that at this point one might wonder if Rails 4 (and a complete redesign) may not be the way to fix the security issues.

Maybe also, if ruby programmers learned to program (instead of doing banana driven lingo development) or committed suicide throwing themselves from a cliff (along with PHP developers) (like lemmings) we could also have a boring yet more secured internet.

I am voiceless: why would the f*ck would someone loose such that much time on a trivial, yet annoying task?

That is the first lesson you have in assembly language: program in assembly language, then in C because it spares you the time (and the mistakes involved in the process) to do such a thing.

Thousands of men year efforts and wisdom ruined in a post, showing how people have too much time on their hands, and so few imaginations (well he could have written something interesting on how to display p0rn pictures in ASCII art at least).

Well it is a known QA practice: never base incentive on metrics or people will cheat one way or another with the metrics. If your dev have a prime based on SLA or tickets solved guess what? You are giving them an incentive to cheat. You will have nice figures to show your investors, ypur stock options' values will raise and coder will be better paid. Everyone is happy, who cares about the truth, the unfairness, the lie. This is just mis placed moral. Stats that can be tricked are the prozac of our society. It make the metrics describing a situation improve with mutual benefits for (almost) all the stakeholders.

Who cares about the customers or minorities anyway? I mean not on the paper but honestly?

I noticed http://en.wikipedia.org/wiki/Binary_heap had a (slighlty) improved version of the binary Heap copy pasted from the same book.

Unless you have a sensitivity to the initial conditions, hence you have a chaotic system. Which happens as fast as n body interactions in a gravitational field (but how many bodies/iterations do you need, which initial conditions makes the error a problem?)

But as I stated earlier, I think I have to check first because I am not that convinced any more on the performance point of view that JS has a problem, and float representation is not a JS problem, but a problem global to all CPUs.

Well it can be more than 10^-12 sometimes and the problem is not in physics but in trading when errors stack up. That's why I prefer when e-commerce solutions are based on fixed point arithmetic.

Even though canvases are still not homogeneous in terms of performance from browsers to browsers, some works fairly well.

Without tests at first glance I might be having false asssumptions on modern JS optimisations: NaCl (C) http://juliamap.googlelabs.com... VS http://www.atopon.org/mandel/# does not strikes me as JS being an order of magnitude slower than NaCl.

It looks like I might be very wrong.

I will make my opinion later by calculating decimal of PI or something like that in C and in JS to benchmark.

I think I need to update my knowledge. :)

Well, I would discourage playing with math if accuracy was important. Just open firebug and multiply

  >>> 10*1.1198 
  11.197999999999999

This limitation is intrinsic to IEEE 754, and no alternative are in the pipe (IEEE854 seems stalled).

I have been working for the web ads industry and canvases were pretty disappointing in terms of performance when the number of sprites were growing up. The funnier part was the inconsistency in result amongst the browsers.

So simulate as much as you want, just don't expect to beat flash or native client in terms of performance...

You really want to play with physics/math with ECMA 262? O_O (hint JS knows nothing of integers) Floats are way to slow (and faulty when div/mul are called) compared to int to do anything serious. All 3D engines tricks are about doing complex math with integers (EDIT: or other tricks http://en.wikipedia.org/wiki/Fast_inverse_square_root#Overvi...)

Are any jailbreaked iphones with privacy patches installed being leaked? Xhi2 analysis is not only about what triggers the correlation, what does not trigger the correlation is also important. My guess is jailbreaked are underrepresented in leaked UDID either because jailbreak is shielding users or because users able to install a jailbreak are more aware of computer security issues. Regular Iphone are cell phones remotely controled by a 3rd party, jailbreaked iphones are computers you control. I am no paranoid freak, I am just a regular sysadmin with a pretty low security awareness.

Well, I like to exaggerate a little bit. Especially since sociopathy/asperger are rather ill defined. So discard all my remarks as pure troll (don't feed the troll :).

The real point is there are no truly acceptable positive feedbacks if one does not equally express negative feedbacks.

So ... one should not whine for getting flamed even if it is socially unacceptable to discard all this work because that's the path for improving...and later maybe getting praised.

because if you are really a coder you prefer negative feedbacks than a false confidence. Even though it is yet socially unacceptable, social rules are stupids.

You cannot earn any glory in publishing your code if people don't tell the truth. To be pleased by one «I love what you do», you should ready yourself to get a couple of «you are doing crap». Coders are not expected to publish good code at first, they are expected to improve their work through sincere feedbacks. That is our culture.

Social norms are unproductive when it comes to work in cooperation.

The fact that Asperger (sociopaths) are 10 times more prevalent in coding expertise might not help.

Excellency in coding is an aristocracy that needs no excuses and don't fear critics. You shall not fear the fight if you believe in your creation, because good design can stand the assault of the best criticisms.

Social norms are only their to protect a hierarchy of status. Truth protect the hierarchy of competence.

If you are just a hipster searching for a social status based on consensus then flee for this is war against you. THIS IS SPARTA!!!!!

Thanks. I do despise stupid brainless people: they are a threat to all the things I believe in: democracy, science, fun, sex, good taste & style.
