Python provides the buffer interface, however (which `array` module implements), which links Python's buffers and memoryviews to numpy arrays to multiple other 3rd-party array-like and table-like types and structures.

Given that it's the decompression speed that is typically the "user-facing" part in many contexts (with compression being done by automatic jobs etc), such a difference in decompression speed is pretty awesome indeed. (which

And then you quite quickly get to a point when you need to curate an "awesome list of awesome lists" like https://github.com/sindresorhus/awesome or "awesome list of awesome lists of awesome lists"

Yea that's a good one. Same with numbers and special characters. Someone needs to make a velocity-sensitive mechanical qwerty keyboard :)

Thanks a million, never seen this one, looks quite awesome!

If we’re really talking “at the speed edge”, low hundreds of nanos would be already considered too slow these days :)

Could anyone recommend a good “terminal/shel guide” for people not familiar with the shell and gnu tools at all? Like ls, cp, less, find, grep etc and why is it all needed? (not for myself; for some friends who are learning coding on m

Ditto re: doors :) I’m renovating a Victorian house (Dublin centre) and it took us a good few weeks to pick a front door and its colour so it blends in the neighbourhood. I was surprised to find out there isn’t a single book on that.

Some companies already do have obligatory “compliance” leave, especially in the finance field.

Except for the 1-indexing part.

It solves everything if you're happy with C++. Not everyone is, I would personally prefer Rust as it's a better language. (Source: using Python/C++ at work, contributed a lot to pybind11)

> I'm not sure why someone would pick OCaml in 2019 You definitely would if you already have millions of LoC in OCaml.. like Jane Street does. For a random person, I would agree. I tried it myself for a few personal projects (I know

There's also things like numba - basically a Python decorator that lazily JIT-compiles Python functions to LLVM, and supports numpy. For scientific work, it's quite often hard to beat (and sometimes somehow beats a raw c/c++

Python 4 will not "break everything again", it will be equivalent to a point release. It has been already explicitly mentioned.

> most tasks where you have < 1mil rows of data Now that's quite a generalization... most tasks? If all you're doing is a=b+c then perhaps. I work in HFT and even for trivial data exploration I would never even consider touc

Plus the lack of vim mode.

Was about to say that myself. How many programmers (especially Linux ones) use vim? Out of the emulations I’ve seen, JetBrains one is perhaps the closest to real vim (albeit not without a few weird corners). If Pharo is so flexible and modu

Oh - thanks for noting! SF Mono looks pretty cool, I missed it somehow (is it available on 10.12?). I guess I'll have to dig it out of Terminal.app now to try it out.

I use Spacemacs ONLY to have access to Magit. And I've successfully converted many non-emacs non-vim folks to use it, all of them love it.

As a DJ, you would need that music preferably in 24-bit WAV, which is not something you get from spotify and soundcloud.

I can't find anything better than Monaco for myself. That's something about it aesthetically pleasing which I can't quite explain. Fira Code probably comes second.

I’m not an fpga engineer myself in my firm, so I can’t answer that with certainty, but one thing I know for sure is how strong the “not invented here” syndrome is in this kind of shops, so you can guess...

by aldanor 8y ago
I’d say typically not, there’s not much to use as most of the FPGA code would be know-how and optimised down to cycle-level for each particular exchange.

This shouldn't have been downvoted.

My personal view: C++ has issues and problems because it's too old and it's not going to get rid of the old baggage, hence it will have to carry it forward while adding new stuff on top (concepts, ranges...). Those issues are not

In HFT shops, we usually categorise stuff as “hardware” (fpga) and “software” these days. Low-latency typically means sub-microsecond.

Somewhat related and also Rust - I’ve recently put together a crate for frp-like computation (in terms of streams and all that, but the use case is somewhat close to adapton, although simpler), for my own use but then figured I’d share it b
