Or maybe you are expecting one context and the author is using a different one. This is quite likely given the author (a well known hacker, and having worked in particular on this exact problem through his project codeville)

Concerning the 35 hrs/week: it is the legal duration for work above which you are supposed to pay a higher hourly rate. It is NOT a maximum, and many people work more than 35 hrs/week (the figures for working hours are pretty similar betwee

No, I think it is a terrible example at so many levels it is not even funny. The only interesting thing about that example is how almost any other solution is much better. I would consider quicksort to be a quite simple example if you use a

if you are interested in new insights about complex numbers and analysis from a geometric POV, this book is wonderful: http://www.amazon.com/Visual-Complex-Analysis-Tristan-Needha... and quite accessible.

Agreed - the problem is not recursion, but that it becomes useful for actual complex problems. I understand recursion pretty well at a conceptual level (my background is math, mostly self-taught for CS), but I have a hard time using it for

inlineCallback overhead can certainly become significant. Saying that it is not an issue because it is nothing compared to IO only works if you are not CPU bound in the first place - but for many applications in python, you are CPU bound. U

It is not that simple in real life, unfortunately. Even ignoring the fact that inlineCallbacks's overhead is significant, inlineCallback forces you to serialize things which may be run in parallel. If you do yield f1() yield f2()

I have to ask: what reasons do you have in mind for the "sketch why this could happen". I have never worked for a large corporation, and besides usual miscommunications between departements about official policy, I cannot find any reasonabl

You sometimes see one or two Apple people at speech conferences, at least it was true 2-3 years ago. I cannot imagine that not to be the case anymore.

For the C rationale: yes, I want to use clang to generate cython interface files from pxd (I have an horrible hack using gccxml ATM: https://github.com/cournape/cython-codegen ), and I would prefer writing the tool in python from ctypes. D

Does anyone have experience with using the C API from clang ? Does it improve from former versions (doc, stability) I would really like to get a reliable C header parser for code generation, and gccxml is just damn awful to use.

I know very well about the use of static within compilation unit, but I was referring to "public API" (more exactly: API between components of your application). This is especially excruciating once you need to use various libraries outside

I don't think it is an issue of technology (typedef, etc...) as much as an application target issue. Using short names in a language without any kind of namespace support can only work for a certain type of applications and developmenent or

Don't hesitate to ask on the ML (while I know numpy fairly well inside out, I am not the best person to talk about parallelism). There is also a lot of talks available in the scipy conferences video. See http://conference.scipy.org/scipy20

There is not effort to "get numpy working on cython" (I am not sure what it would really mean). There is an effort to refactor numpy code between the python-dependent part and the more core, "pure C" part, which would help. Adding pypy as a

The big issue here is that most scientific code in python runs on top of numpy, and getting numpy to work on top of pypy would be challenging. I understand that relying on a C extension compatibility layer would make things slower at first,

I have never used the parallel stuff in ipython, but my understanding was that it was more for cluster-kind of stuff. This is getting significantly rewritten, also, so things are changing there. But the way most people use parallel stuff in

One thing to note is that the authors are foremost very well known machine learning researchers. Reading Bottou's PhD thesis (in French unfortunately for most HN readers) was kind of depressing in a way, when you see the kind of things he d

I am curious about why you think numpy/scipy does not fit that bill ? Python is a straightforward general purpose programming language, has a lot of stats functionalities, can access GPU functions. While python's story for parallel programm

primary sources is known to be one of the worst way to study any field, especially when you are not familiar with it, because you lack the context, and because they are rarely written for the profane. This is all the more true for maths: ha

Yes, this is a real pain point, because that's exactly why you need everything to be non-blocking in the libraries you are using with something like node.js (things like twisted in python have exactly the same issue). Not only do you need n

So it is more an architecture issue with conventional hardware ? It makes much more sense to me with this explanation - the issue is the same as in most real-time systems then (like in embedded hardware for audio gears, which is more famili

This seems a bit surprising: what is the latency coming from the NIC to the motherboard ? I somehow doubt the latency due to distance within one piece of hardware matters (current CPU cannot do much more than a few 1000s cycles for the elec

As someone who studied maths before programming, I think the only real predictor is whether you are comfortable with discrete mathematics. I don't find most mathematics I learned (undergrad + stats/EE at graduate level and above) very usefu

I am not familiar with leiningen or clojure, but it looks like you are just adding a list of requirements + version, which is exactly what you get with pip + requirements.txt file ?

But what's the difference with python at that point ? Is is because the JVM makes it inherently easier ("one" jvm, one bytecode, no difference between version/build options for C extensions) ?
