*Rant* No Reply-To?
by Timothy Baldridge March 17, 2011

March 17, 2011

Why is there no "Reply-To" in the headers on this list? Whenever, in gmail, I hit "reply" it automatically sets the to address to the "from" field in the mailing list e-mail. So I end up e-mailing the person directly instead of the list. This is highly frustrating.

phb impression from speed.pypy.org
by Massa, Harald Armin March 17, 2011

March 17, 2011

Hello, I really love the improvements to the clearity of speed.pypy.org In the last days I have dropped some times on that page, aaaand... although I read the description and understand it, what my mind FIRST processes from the How has PyPy performance evolved over time? picture is that "performance got worse" Yes; right after that I read the small print of "smaller is better". But still... my eyes tell me "it got worse". Would it be possible to think of a presentation that allows to GROW … [View More]

I'd imagine a default 'reply-to-all' would be much more harmful, unless you can apply these settings based on a filter.

This is something that Java, and C#, and C++ all require. Yes, the Python interpreter should never crash because of user mistakes. -- Regards, Benjamin

Any Multithreading Primitives?
by Timothy Baldridge March 15, 2011

March 15, 2011

Does PyPy have any sort of multithreading primitives that are available in rpython programs? I'm specifically looking for CAS. I can probably simulate a mutex with CAS. Or do I have to drop down to some sort of assembly generation to atomically update a object reference? Thanks, Timothy -- “One of the main causes of the fall of the Roman Empire was that–lacking zero–they had no way to indicate successful termination of their C programs.” (Robert Firth)
