Re: DIP 1034--Add a Bottom Type (reboot)--Formal Assessment Begins
On Wednesday, 3 February 2021 at 18:24:06 UTC, Imperatorn wrote: Is there a short explanation of why this was done and what it enables? Personally I'm excited to see this... Strangely enough there is a long running 'net wide disagreement on what an assert is or does. Some regard it as purely a debugging tool used as a programmer aid that is expressly turned on by the programmer, and others (such as myself) regard it as a way of stating, and enforcing the contract, provided by an API. And as such, people with the latter mindset wish the compiler would warn us if that contract is potentially violated on any path, and conversely, wish the optimizer to act on the information it provides. By adding it to the type system, it expresses and clarifies the intent of the author of the code, and expresses it in the compilers terms, ie. a type. In my day job, I have found the only resolution to the disagreement is to create two different facilities with two different names to permit the two groups of humans to get along. In my day job instead of "assert" we now have "log_If()" that are opt-in programmer debugging tools and "error_Check...()" that enforce.
Re: Online D Conference
Motivating Questions: What is the difference between an "Online Conference" and watching something on youtube? If the answer is nothing, don't bother with a conference, just create a youtube channel. If the answer is a conference is nothing like watching stuff on youtube... you better consciously and actively organise it to be different. What is the difference between "Online" and "Meat space"? If the answer is "Nothing", you will have a guy, selected by a papers committee, standing in front of an empty hall talking at the camera. Otherwise you can think much much wider... * screencasts * massively multiprogrammer online sessions * remove the paper selection committee and replace it with redditlike upvotes * or write a paper like you write a library, collaboratively, on github, with PR's. * Have game sessions, virtual choirs, ... whatever can turn online handles into humans. Disclaimer: I was involved in arranging linuxconfau 2019 and observed first hand that meatspace conferences impose huge and tight constraints on what is possible... Some things are about meatspace are very nice (eat! drink! be merry!). Some things cost a huge amount and decrease the value of the conference. (Very tight limits on number of tracks / papers, attendees, health and safety, transport, accommodation, flights, .)

Re: Unit Testing in Action
On Friday, 20 October 2017 at 14:04:25 UTC, Mike Parker wrote: https://dlang.org/blog/2017/10/20/unit-testing-in-action/ I'm somewhat late to this party but anyway, here is my two cents on the way Unit testing needs to be tweaked. One of the values of Unit Testing is Defect Localization. ie. In a well designed unit test suite, tell me which test failed, I will tell you, to within a few lines, where the bug is. However in the presence of setup and teardown failures, we lose that. Ideally we should differentiate between failures that occur during setup and teardown, versus exceptions occurring in the behaviour under test, or assertions on the validity of the result. ie. Failures under setup and teardown are not failures of the behaviour under test. The only thing we can say about the behaviour under test in these cases is, that it “hasn’t been tested”. Hopefully the behaviour that failed during the setup and teardown is explicitly tested elsewhere. ie. We should stop at the first test that fails at a point other than setup and teardown, as this is likely to be the cause, for the cascade of failures in setup and teardown of other tests.

It turns out in the wild that pure Unicode is not universal - there's lots of dirty Unicode that should remain unmolested because it's user data, and auto decoding does not play well with that mentality. As a slightly tangential aside. https://lwn.net/Articles/686392/ There exists a proposal for a linux kernel module to render the creation of such names impossible. I for one will install it on all my systems as soon as I can. However, until then, my day job requires me to find, scan and analyze and work with whatever crud, the herd of cats I work with, throws into the repo. And no, sadly I can't just rewrite everything because they (or some tool they use) doesn't understand UTF8.

And in practice the only wheel that works is shutting everything down and restarting everything up. Suddenly "No stateful communication" is looking really really Good. Coap clearly has thought these issues through.

Re: Lang.NEXT panel
Yes! That is only one of the reasons to have that ability. Almost more important is automated reasoning about very large codebases. What are the global properties?

That should be quite easy to implement now in D, and once done, would give much needed room for breaking changes we feel should be done. Pike seemed to be extremely satisfied they did it. Personally, I wouldn't be comfortable trusting such a tool. Besides, I find that upgrading a codebase to a newer language version is one of the most trivial tasks I ever face in software development - even in D. It's a cute trick, but not a worthwhile use of development resources. I very much think the opposite, drawing from many years of hacking into large codebases. I'm completely with Rob here. On a large codebase, even the slightest manual or semi-manual change is painstaking to plan and execute, and almost always suffers of human errors. I got convinced a dfix tool would be a strategic component of D's offering going forward.
