I've been working with machine learning in production for more than a decade. The biggest challenges I see are actually organizational rather than algorithmic when it comes to delivering value. Most of that comes down to the additional

When you remove the context around statements (thread about rust concurrency), it's easy to make a statement into overblown nonsense. You may be interested in the broader analysis contained in the link from parent comment, about the ty

This is actually pretty amazing. I wouldn't normally trust a single author implemented project to sit between my application and my database, since that is a rather critical single point of failure. However, a grep that fails to find `

As a fan of Rust, this seems like the perfect application domain for "fearless concurrency". Having gone through the bowels of a few different connection pool implementations in various languages (because they had bugs in producti

I'll go edit the post to make it more clear that you need to follow the links through the code to get the actual answer... it's more involved than a single snippet.

Rubinius is neat, but for me personally (and I think most of the community) it's performance. Writing C enables optimizations by hand that still yield very significant performance gains over the best of what any other high level langua

Matz mentioned off hand at the last Ruby Conf that Nobu has been experimenting without the GIL. It's scary because running code without the GIL will expose a lot of existing concurrency bugs that have been safely hidden thus far. A lot

Would love to have questions like this on Omniref for other code readers. VALUE is in fact a pointer, ie a raw integer, which is pass by value in C, so it's fine to return.

Do you happen to have an old version of Inconsolata font installed? In this case, chrome and firefox both prefer the font on disk to the google webfont specified in the css, which causes a display bug.

We're planning a C memory management follow up, with a focus on Ruby GC and its recent improvements. We're also looking for authors to feature who write similar content, so if you wanted to do a series on a particular chunk of C y

Thanks wasd. The next thing you could do, is highlight some C and ask the community any questions you have. I intend to keep writing the series, since there's easily enough material there for a book. If you signup for an Omniref accoun

As you point out, the speed at which programming is evolving makes maintaining relevant experience difficult for a human, which makes programming at least different in degree from other professions. The ultimate goal is to build a hive mind

I love the power of the unix shell. find | cat | grep would get the job done just as well if you had all the source in an accessible file tree, but I don't think you'd see any performance increase as the bottleneck is still random

About 2 hours. The regex is IO bound, on a text column with 87GB + 68GB postgres toast. It's on a new 1TB 3k iops EC2/EBS ssd volume, which seems to be able to sustain about 20MB/s.

The dynamism of ruby does make things difficult, if not impossible, to fully realize until runtime. Incidentally, tests are popular in ruby, and give us runtime examples to work with for stronger analysis. If we're just spitballing, as

Great example. A code browser is on our radar, but it would be a big enough undertaking to do "right" that it hasn't made the cut for low hanging fruit. Our next step may be to just hyperlink all methods/classes/con
