I was using the "bc" command line calculator. Turns out it's rounding the exponent. The revised number is correct, though.
Moore's law: Transistor count doubles every 18 months. Assuming 40 years at the company (it's a bit less) that's: 2^(40/1.5) = 67,108,864 The 62 Core Xeon Phi has 5 billion transistors. Divided by that number is: 149.…
Would make sense. Michael Bender is a co-author on that paper and he apparently works for Tokutek, judging by this presentation: http://www.bnl.gov/csc/seminars/abstracts/Bender_Presentatio...
As I understand this, this wouldn't automatically protect you from race conditions. If you have a shared variable x then a statement like x += 5 may be fine depending on whether it is implemented as a single bytecode…
"I'm thinking of doing a PhD in Germany" I'm not discouraging, but once you're considering a particular position, please try and talk to previous PhD students of your prospective supervisor. Germany has hardly any…
The blog author didn't actually have two factor authentication enabled. The headline is wrong.
That depends on the kind of scientific computing you want to do. Haskell has the repa library [1] which is very nice for working with (multi-dimensional) arrays at a high level. Performance is decent (I don't know if…
Small correction: "Plankalkül" which translates to "plan calculus"
Or create a (resizeable) image that is case-sensitive. Not sure what the performance overheads of that will be, though.
I think he/she meant that birds can't survive in space. The pigs at least seem to have some sort of bowl around their head.
Note that in many dynamic languages (and I think that includes PHP), syntax checking is done right before you try to run it, and type checking is performed at runtime. When you're programming in a Java IDE, these kinds…
Yes, for the AI class they promised to give you a signed statement of accomplishment. IIRC, this statement will also tell you how well you did in relation to all other students (including Stanford students).
Well said! I don't think I found a argument in that article that I would agree with. The mentioning of Perl as a great example is probably the worst. The purpose of a programming language is to express things as…
That will most likely bite you since you're giving a pure type to a non-referentially transparent function. There is a reason why random functions are in a state monad or IO.
That's very easy to explain. A low-pause GC requires a concurrent garbage collector. Writing a correct concurrent garbage collector is VERY tricky, so you usually start with something much simpler. Concurrent GCs…
Hm, this doesn't mention support for lexical closures (not turned on by default, of course) which supposedly has been merged into the master branch. I sure hope this will make it into the release.
There is an interesting book, "The Spirit Level: Why Equality is Better for Everyone" by Richard Wilkinson and Kate Pickett, that makes a very strong argument that in developed countries inequality is correlated pretty…
I understand that this is meant just as an experience report, but I have to say this article didn't convince me in any way that this rewrite was a good idea. Obvious questions: 1. How does the performance of the new…
Given that some people have separate accounts for games, I wonder how accurately that number reflects the actual number of users.
Looking at the instruction set it doesn't even support subroutines. It would only need a way to get and set the current program counter (like ARM) and you could implement subroutine calls using push, pop, and jmp.
Actually, there are microkernels running in a vast amount of mobile phones nowadays. They typically don't run on the main CPU, though, but on various controller chips. Microkernels are practical -- they just have…
In the video he mentions it's about 5000 per night.
Both have a hostile attitude towards privacy, claiming that it's dead, trying to make it look old fashioned and irrelevant. [Citation Required]
Actually he bought Pixar to turn it into a hardware company. John Lasseter is probably the bigger reason why it became such a successful animation company. Of course, thanks to Steve the company survived long enough to…
Do you have any references for your "as fast as C" part? That seems like a very dubious claim. If your ultimate goal is performance, I believe PyPy is fundamentally flawed because it already introduces two levels of…
