Yeah, I often want a place to just gab. I kinda do in my blog, but that's more often something that is more finished since I feel like a blog post needs to have some more length to it: http://dpldocs.info/this-week-in-d/Blog.html I tweet from time to time but it is hard to fit code examples in there, like this one last night https://twitter.com/adamdruppe/status/1300914727627960320 yeah that took some trimming. of course if you are on the #d IRC channel you can often find me basically talking to myself as I think out loud about whatever code I'm doing at the moment... lol But what I think would be really cool though is like an internal twitter... no size limit but also a culture that there's no expectation for length and quality.

Not only is Symmetry Investments hiring D programmers, they are also generously funding two positions for ecosystem work under the D Language Foundation. And they've put up a bounty for a new DUB feature. Read all about it here: https://dlang.org/blog/2020/08/30/symmetry-investments-and-the-d-language-foundation-are-hiring/ This is a great initiative! It's also a great opportunity for up-and-coming D contributors. I know that if I had this chance back many years ago when I was unemployed I would have jumped at the opportunity. So if you're in a similar position don't hesitate to apply!

I meant having several hashes in dub cache. Then if the user changes the hash algorithm dub checks calculated hashes against cached ones and avoids total rebuilding. Hmm, probably I was too confident. I've implemented support for both sha1 and sha256. It takes about 30 lines of additional code but what is worse the code uses classes now and dynamic memory allocation. I would avoid it. But in other it works as I expected: ``` dub build --hash=sha1 dub build --hash=sha256 ``` I do not test it in big projects but building dub does not show any difference in performance

Yesterday I thought about it and now I believe that if you change sha1 to sha256 or vice versa then dub just rebuild all because sha1 and sha256 has different sizes so cached hashes will be different to calculated ones and collisions are impossible. No need to support mixed mode. The drawback is total rebuild on algorithm changing but I suppose it will be seldom operation. Another way is to having several hashes simultaneously and select one of them depending on option value. Implementation of this will be simple.

A server approach would probably scale much better, if the intent is to speed up the developer's CTR cycle. But in any case, thanks to Symmetry for doing this! This is huge. We need both a fs-watcher daemon support and "offline" incremental build support, based on SHA-256 (note that git is moving away from SHA1 to SHA256 [1]).
