Thanks, I’ve added it to the article.

Absolutely. But since we still have to support SSLv3 from 1996, I wouldn’t hold my breath. :(

RC4 has no known practicably exploitable weaknesses and is well supported, insofar the “ancient” is actually working in its favor. That said, if you know as much as you do, you don’t need that article and can fine tune yourself. It’s for pe

You could put it that way. The point here is that the threshold of interest needed to apply is much higher for women than for men. These barriers are real but you, as a man, can’t really judge that because you hadn’t to cope with them. You

The success of outreach programs prove your “Women just weren't interested enough to put CS in their application forms for college.” wrong. Unless women changed significantly since the mid-nineties which I doubt.

I have added them (and the ones you and Alex added) to the article. Feel free to send me more.

You get ePub, PDF, mobi and iPad-optimized PDF. I usually read the latter, it just looks gourgeous.

Yeah sometimes I wish there were a warning whenever someone defines a function with [] as def arg.

I think it’s just attrition by explaining the GIL problem over and over again. Nick is one of the major core developers and probably just fed up by the topic. So this bit of snark is all the pay he’ll ever get for his work on CPython.

The counter is not (even while some people try to turn it that was): THREADS SUCK, WE WON'T ADD THEM BECAUSE WE DON'T LIKE THEM. it is: given the circumstances (which Nick outlines verbosely) a removal of the GIL is not pragmatic. And this

Not sure if you’re trying to troll me by taking it out of the obvious performance context but anyway: The performance penalty due to the usage of a un-JIT-ed scripting language?

For one, they didn’t start out with the baggage of nearly 20 years but started building a JITed VM which was polyglot by design.

As it has been pointed out for several times: the adoption of Python 3 is doing just fine. It has never been expected that everybody will be using Python 3 today. But look at all those current efforts at Canonical, Django, Twisted…it’s not

That’s essentially what __future__ imports are for – things that go further would be simply too much work and Python 3 was about shedding weight, not shipping essentially two interpreters. (while they are very similar from outside, the inna

If you’re using python, the performance gap between processes with message passing and threads with locking is the last of your problems, believe me. The big difference is that processes are much more robust and testable. The cases where th

I find Nick arguing pretty much to the point and the quote above was ripped from it’s context which is a huge section balancing the arguments against each other. tldr He argues there are better ways for scaling out than threads and removing
108.
by hynek 14y ago
The article doesn’t say multi-CPU scaling isn’t necessary. It says that threads are usually the wrong answer anyway. There are great process based ways to scale out – look no further than Erlang to see it’s true.

There is no such thing as "Python 2" or "Python 3" modules. There are just modules that will go belly up because they are incompatible with one or another. I presume you mean that you can’t access your old Python 2 modules from a new Python

The general opinion is that you shouldn’t use threads unless really necessary. Processes or eventlets are usually preferable. Python is not the only high-level language with this "problem" btw. FWIW, my personal opinion is that the future o

Ironically, Py3s purpose _is_ to fix Python’s warts. You just seem to be lucky enough to not have encountered them yet. :) Python 3 was about _losing_ baggage so we can start adding features again. The fact that Python 3.3 has a lot of more

by hynek 14y ago
You seem to presume that if there weren’t Python 3, we’d be busy removing the GIL. That is not the case, removing the GIL has no priority for reasons already too often discussed.

by hynek 14y ago
And what exactly has that to do with Python 3.3? You spoke about overwriting CentOS’ /usr/bin/python with Python 3 but don’t have enough “engineering talent” to do proper deployments? You speak about economical factors, but doing broken dep

I’m not sure what’s half-baked about a 3 years old ticket for a Python version that has never been declared as usable. (3.2 was the first production-ready Python 3)

by hynek 14y ago
Uhm I don’t get this: yum uses /usr/bin/python, why should it care about /anywhere/python3? Also we have many CentOS 5 servers but won’t let dictate our Python based software development by their Python 2.4. So we just rolled our own RPMs a

I respect your opinion and maybe you’re in a unique position that makes Python 3 really awful to you, but in general your comment seems more like a knee-jerk "lolpython3" reaction that was appropriate while 3.0 & 3.1. But now, that situ

You can’t hide the complexity of doing that right but OTOH the ipaddress objects have useful str() methods: >>> str(ipaddress.ip_address('127.0.0.1')) '127.0.0.1' >>> str(ipaddress.ip_address('::1')) '::1'
120.
by hynek 14y ago
Ehm, how do you check whether an IP address is inside of a specific network with strings? Or how two networks overlap? How many addresses a network has? Hint: there’s more than /24 networks and IPv6 makes it even more complicated.
