Several times, sometimes to find out when an incompatibility was introduced in an upstream dependency to find the maximum compatible version, but usually to find the commit that introduced a strange bug.

The process is always the same… Write a unit test, start bisect, check test select next bisect step, repeat. If your last-known-good and first-known-bad are correct, it always worked for me.

Since this was a question about a lemmy feature, I’m talking lemmy here, arguing about fediverse, TCP/IP or electricity numbers/servers/plants doesn’t seem usefull in this context. Providing a link to a server that to your knowledge (you provided the reason) hosts illegal content can be seen as participating in this crime or at least advertizing. (Disclaimer: I’m no lawyer, I just remember whole BBS being seized for providing lists of (international) phone numbers to BBS that hosted warez and there’s stuff that’s worse than warez).

There are a few different things I’d like to mention:

• I don’t think, that there is such a thing as a massively defederated instance exists right now. The most blocked instance is blocked by about 11% of the instances, followed by two instances at 6%
• Even if the die hard scene users would know their instances, not every random troll or spammer would.
• This doesn’t address the possible legal issues of publicly announcing where someone could find illegal content
• If “small queer instance” refers to beehaw… That’s the second largest instance there is as of today according to https://github.com/maltfield/awesome-lemmy-instances

And lastly: If you’re new to the fediverse you maybe shouldn’t run your own instance in first place. Helping reckless people pull reckless stunts is a bad reason to promote a feature.

Currently it isn’t and I don’t think, that this would be the best idea ever since it could be misused as some kind of index to find bad instances. The defederated-list is available to the public and thus the defederating instance could in fact be “advertizing” the instances they defederated from (“Look, we don’t want this stuff here, but these instances are for [right-wing|transphobes|bots|spammers|porn]”)…

Depending on where the instance is hosted or where the admin lives, it might even be illegal to in fact point people to places where they can find certain things.

I’ve seen the fun of “prints everywhere” in production when a colleague forgot to remove a “Why the fuck do you end up here?” followed by a bunch of variables before committing a hot-fix… Customers weren’t to amused…

Edit: That was a PHP driven web shop and the message ended up on to of the checkout page

I seldom use profilers because I seldom need to. It’s only usefull to run a profiler if your programm has a well defined perfomance issue (like “The request should have an average responsetime of X ms but has one of Y ms” or "90% of the requests should have a response after X ms but only Y% actually do).

On the other hand I use a debugger all the time. I rarely start any programm I work on without a debugger attached. Even if I’m just running a smoke test, if this fails I want to be able to dig right into the issue without having to restart the programm in debug mode. The only situation, where i routinely run code without a debugger is the red-green-refactor cycle with running unit tests because I’ll need to re run these multiple times with a debugger anyway if there are unexpected reds…

What enables me? Well there’s this prominent bug-shaped icon in my IDE right besides the “play button”, and there’s Dev-Tools in Chrome that comes with the debugger for JS…

Running your code without a debugger is only usefull if you want to actually use it or if you’re so sure that there aren’t any issues that you might as well skip running the code altogether…

The main difference between these two instances as I see it is that lemmy.world gets a whole lot more media coverage, attention and direct links than sh.itjust.works. You have to do research or visit join-lemmy.org to find a link to sh.itjust.works and then their tagline starting with “A bilingual (EN/FR) general-purpose instance located in eastern Canada! Powered by 99% renewal energy!” might just keep some uniformed (as in how this federation-thingy works) non-canadians from joining (yes, I left out the second part of the tagline, assuming most people who’d be put off by the beginning wouldn’t read any further).

I think it’s a lot less nefarious. About every post or article about Lemmy that links to Lemmy instances has links to (in this order in almost every article I remember) lemmy.world, lemmy.ml and beehaw.org. Of these 3 only lemmy.world accepts new users without vetting. Lemmy.ml doesn’t accept new users at all and beehaw doesn’t really look that welcoming to someone who knows they might stir some shit up in the future and also getting into beehaw requires more effort. So with lemmy.world usually being the first on the list and additionally requires the least effort to join, this is where all the world and their uncle end up on. They just get the biggest unfiltered influx and with that the biggest amount of toxic people. (I want to make sure that I’m not calling lemmy.world users lazy or toxic or anything like or that this is their target audience. It’s just a fact fact that someone who can’t be bothered to do research and/or “write an essay” as someone called it, will most likely end up on lemmy.world)
