Awesome! And thanks for linking directly to the article on ycombinator. If they're still penalizing articles for direct links, they should realize already that links are a thing on the internet. Ali

This is great! I've been pushing D in my workplace, which is full of Python programmers and this is another good example I can use showing why D rocks. I'm going to introduce this and then push hard the line "Now you have D in the build mix why bother with C and Python at all?" Thanks, Stew

A lot of the comments were about how stupid I was for not just using ctypes or cffi. I tried today and both of them are horrible. As I say in the blog post below, either they didn't read the article (people on the internet commenting on things they didn't even read? Shock! Horror!) or just aren't lazy enough.

Very good read. I my opinion your work with integrating different languages with D is the most exciting stuff going on in the moment. If you had an RSS feed, I would subscribe. Wasn't there a planet D in the past?

Thanks! I guess you could either follow me on github, the blog itself, or Twitter.

I've been subscribed on feedly without any issues. I can't recall what I actually did to subscribe as I can't seem to replicate it, but you can try https://atilaoncode.blog/feed/ Can't say for sure with other RSS readers.

There needs to be a variant of "mansplaining" modified for Python users.

Agreed, and there also needs to be a variant of prison, modified for people who post dumb comments on Hacker News.

Whatever the language, I like the "show me the code/graphs/benchmarks/disassembly/data/something/anything" approach Atila used in his blog post. When I wrote a blog post about why C const is practically useless for optimisation, I lost count of how many people smugly pointed out that const "should" go on the other side of the *, as if that made all the difference. If they actually tried it they'd see it makes zero difference because "int * const x" is even less useful for optimisation.

I basically just ignored any of the comments about ctypes or cffi having looked at them briefly once like 5-10 years ago and throwing up my hands. But I also throw up my hands a lot!

I didn't know anything about them last week, so I didn't think I could reply properly. After looking into them today I just shook my head a lot. It's incredible the lengths that people go to justifying their pre-existing beliefs. At this point, I don't know how to convince the masses if "nanomsg in Python in 4 lines of code" isn't enough!

Perhaps a side-by-side comparison of how clean the D version would look vs how lousy the equivalent ctypes/cffi version is? Just a thought. T -- If it tastes good, it's probably bad for you.

That was exactly what I was going to do yesterday with cffi and I even started writing the code. Midway through I realised how much work it was going to be and decided that ain't nobody got time for that. Then shook my head vigorously that anyone would dare suggest this was "easy" and in any way comparable to what I'd shown to be possible.
