realtime what? Realtime like C? Realtime like ATLAS or MKL?

Your choice of terms is very interesting! I would say that Protovis and d3 do not take a Grammar of Graphics approach per se; rather, they tackle mostly just the lowest level of the grammar, namely aesthetic composition and some transfor

That's very interesting. What sorts of DSLs are you creating, or can you say?

I completely agree. I like how most responses to your rant hone in on the fact that it's a simple syntactic change, but utterly fail to get the point that composition of stateless functions a la Joy is totally magical, and opens up a whole

Matlab and Fortran are influences for Scipy; in fact, there is Fortran code inside Scipy. I'd love to hear more details about the deficiencies, or how it might be more influenced by those. I agree that the ideas of statistical processing in

Writing it in Cython would have been my solution. No futzing around with 8 or 9 iterations. It would just be fast, and the code would still look clean (unlike the obfuscated garbage they ended up with in the blog post).

Unfortunately, the ord() function call overhead in Python may swamp the difference in speed between a dict lookup (hashtable) and a list lookup (ordinal index).

I was going to do a Cython lightning talk, but the organizers indicated that we ran out of time slots, so I could only give one talk. Half of the audience at PyCodeConf indicated they were aware of the Cython project, although perhaps it w

Maybe and maybe not. GPUs are good for problems where the appropriate data can be placed near the vector processor, a priori. There are many embarrassingly parallel problems where memory coherency does not exist, or where the input data s

Why? Courier is widely available and code is readable and monospaced.

Oh, but he's part of the lore and the canon, so even though the sixth patriarch tells you to stare at the moon and not the fingers pointing the moon, on HN there's a lot of finger-worship going on.

Yes, I hear this all the time. I know that the fancy course 6 kids here on HN would poo-poo it, but it's a very common usage in scientific computing. I can imagine the origins and can hypothesize about why it persists (the festering petri

Greg Wilson once commented that the subversive way to get scientists to use source control was not to pitch it as a code history tool, but rather as a nifty way to sync up code between their work machines, home machines, etc. He said he ha

There is a market, and it's called libraries. Eventually you will use a language where software carpentry and code reuse is a core feature, and tested, modular libraries for not only core algorithms, but also deployment and dev-ops stuff (

The core problem is that you can't solve a problem you don't understand. I imagine that a large number of the twenty-somethings lured into the Valley to build the next wave of YC startups have just finished or dropped out of college. Very

There is definitely a social scene in geekdom now with its own zeitgeist that is independent of underlying intellectual factors. Using the terms from Zen and the Art of Motorcycle Maintenance, geeks used to inhabit just the intellectual pl

Use Cython, then. It's my preferred way of writing C.

We just need to tap into the accelerometer, do an FFT and low-pass on the microphone, and check for a correlation between the frequency of a rhythmic acceleration and the frequency of grunting.

Absolutely.

Can you please point out the parts of my blog entry that are "bitter"? Or was that one line - whose sole purpose was to mirror and acknowledge Zed's colored history in the Ruby world - enough to paint me as a "bitter" person?
329.
by pwang 17y ago
Yes, you are wrong. I wrote nothing further about Rails after that. In fact, the only reason I brought up Rails in the first place was to acknowledge Zed's animosity towards that community.

Our company provides and supports commercial builds of Python along with 40+ other packages (including scipy, numpy, PIL, wxPython, etc.) on Solaris. The Sun compiler is not great, but that has very little to do with Python.
