Which version of awk did you benchmark though? Mawk is pretty fast, for bread-and-butter awk stuff often significantly faster than perl. E.g. perl -anE 'say($F[0]) if /error/' big.log >/dev/null 0.85s

Out of curiosity, why are you using docker containers on windows? For emulate static linking or to provide network/process isolation (and does docker under windows provide "proper" i.e. secure isolation?) or something else e

Thanks, I wasn't aware of this.

That's an excellent reason not to -- I wasn't previously aware that docker had native windows application support on windows.
817.
by patrec 7y ago
I can see three broad reasons people develop on Windows: 1. They want to create a Game or Windows end user UI App (e.g. Overwatch or Photoshop) 2. They write some internal corp tooling or B2B software for windows shops (e.g. gluing some SAP

In what way does docker on macOS interoperate better with the rest of the system than a nix package? I'm pretty sure the answer is going to be "none" – you can build native, including UI apps with nix (not that I recommend th

So why not run nix in docker till Windows gets first class support?

by patrec 7y ago
Nonsense. You can run nix on basically any linux system (not just NixOS) and macOS. Not just theoretically, I'm doing both and am not running NixOS itself at all ATM. It's also the only sane way to build docker images. Since nix i

This is an annoyingly ignorant comment. Nix, unlike say docker, actually solves a problem correctly in a principled way: reliably and reproducibly going from source artefacts and their dependencies to installed binaries/libraries/

Apparently you can generally assume x = x, which seems like a very nice feature and one that's perversely absent in all other programming languages I can think of. https://bertrandmeyer.com/2010/02/06/ref

Depends on the editor, of course, but e.g. https://www.emacswiki.org/emacs/redshift-indent.el (Haven't tried the above, but I've done fairly extensive display hacks with emacs in the distant past, so I have a

This argument sounds quite bizarre to me. Why would a visually impaired programer not manage to set their editor up to show indenting spaces the way they want, or failing that, collaborate with others to do so? It's not like they can b

Just because you're not doing much (any?) interesting engineering doesn't mean you're not creating a lot of value. But it probably does mean that if you really deeply care about engineering in itself you should reconsider y

How would you do attributes?

Well, all things being equal a cleaner and more understandable language is going to be easier to implement, so I don't think difficulty of implementation should be dismissed so easily. Especially when the difficulty of implementation i

Correct, and I think this is what they are doing -- you can optionally keep the sha1s around.

Correct, but backwards compatibility does make a difference here, as in: there are surely quite a few cases where it would not be attractive to use a shortened hash if git hashes are changed incompatibly anyway, but where it will be attract

I'm sceptical of the idea that the good things about python make it hard to implement. Compared to forth – sure! But most of the non-simplicity beyond what's attributable to not being an ultra-bare bones languages comes from organ

If you mean the pseudo-code like quality that (sadly) remains a distinguishing feature, I completely agree. Simplicity, as in terms of specifying the grammar though? Python's grammar is exceedingly gnarly by now and I'm pretty sur

There is truth in that, but also a bit of "he who can't do what he wants must want what he can do". The only reason python still matters (more than ruby) is because of its dominance in ML/datascience. And this ecosystem
