Got a Playwright question - in my tests I'm clicking a button which in the backend sends an email. I tried to use Jest to mock that function in the backend so it doesn't send an email, but that doesn't seem to work. Should it?

I could check for NODE_ENV in the backend and not send an email, but I'd like access to the email contents in my playwright test, but without actually sending an email.

Am I thinking about this all wrong?

@joelanman I've done that in the past, yeah.

It seems to me that one of the problems with Mastodon is that if someone links to a post from a user on another instance, it's a multi-step process to follow that other author.

Note that this is when using the default web UI.

When using (e.g.) Tusky on Android, it smoothes over a lot of that for you.

rogerlipscombe,
@rogerlipscombe@hachyderm.io avatar

@jimfl maybe, but it's not great for new users who are trying to build up their feed.

Also this: following the link drops you on the other instance's web UI, and you're presented with login/sign-up buttons, which is confusing.

So a newbie ends up signed up for multiple instances before they figure out what's going on (if they ever do figure it out).

UK government planning nuclear site in Scotland

https://www.bbc.co.uk/news/articles/c9eze1dzy5no

This is pointless: Scotland is already self-sufficient on renewables. What we need is a new grid interconnect between Scotland and England so we can export our surplus energy to the south!

It's all about the lobbyists, of course:

"Its ambitions for up to a quarter of all electricity to come from nuclear power by 2050 are being led by government-backed body Great British Nuclear." (Who?)

@http_error_418 @cstross

It's probably true that the desire for Plutonium fast breeder reactors for nuclear weapons material has led us to the Uranium-based nuclear power plants we have now.

If we'd not been obsessed with getting weapons-grade Pu, we might have tried some other, potentially safer, options.

Worst downsizing I ever went through (short of "company is bankrupt, go home") was 10%, and that fucked our operational efficiency for a quarter. Spotify laid off 17% and are suffering. The C-suite were fools to assume there was 17% slack in the system, much less that middle management would choose the right 17% to fire (or that competent workers wouldn't see this coming and jump ship to better jobs, leaving time-servers behind).

@cstross yes, and it's not just the direct loss of the 10% that bites you. It's the trauma, and the fact that everyone starts keeping their head down on their own work, and no one feels like helping other people.

Been reminded a couple of times recently that I seem to be the only person who refuses to say 'mouse cursor'. I call it the mouse pointer, to distinguish it from the 'cursor' which is the block or line or caret in your terminal or text-editing environment that shows where your next keyboard input will go.

If you think 'cursor' is the mouse pointer, what's the other thing called?

And if you say 'cursor' for both, what's your usual strategy when you need to clarify?

rogerlipscombe,
@rogerlipscombe@hachyderm.io avatar

@simontatham Windows, as I'm sure you know, calls the text cursor the "caret". I use "pointer" and "cursor" .

celebrating 48K YouTube subscribers by thinking about how x86_64 (currently) uses 48-bit addressing

https://en.wikipedia.org/wiki/48-bit_computing

screenshot of the wiki article linked in the post. the highlighted part is in the sentence that says "The minimal implementation of the x86-64 architecture provides 48-bit addressing encoded into 64 bits"

@fasterthanlime

"future versions of the architecture can expand this without breaking properly written applications"

Good luck finding those mythical "properly written applications".

Question: what's the max time that you'd find acceptable for your unit tests to run?

And I'm well aware that there's a bunch of considerations, no right answer, and so on. Just curious to learn what people think.

rogerlipscombe,
@rogerlipscombe@hachyderm.io avatar

@anderseknert it would be interesting to see variation by language/platform. I know that the C++ folks I used to work with were more tolerant of long-ish build/test cycles.

rogerlipscombe,
@rogerlipscombe@hachyderm.io avatar

@anderseknert in my Erlang projects, I'm happy with somewhere under 5 minutes for unit tests. For integration or end-to-end tests, maybe 20-25 minutes.

Increasingly finding that -generated images on a blog post lowers my opinion of the author — not (just) because of a principled anti-AI stance but also simply because it’s rubbish.

If you’re happy decorating your work with generated garbage I’m just going to assume your standards are that low for everything you do.

rogerlipscombe,
@rogerlipscombe@hachyderm.io avatar

@benjamineskola I occasionally wondered why a lot of blog website templates have a place for an image.

Even before GenAI, would you want an endless succession of bland stock photos, or - worse - my head shot, on the home page?

"Thanks for reaching out, but I'm not interested in working at a company as deeply unethical as Facebook."

That was almost 4 years ago. Haven't heard anything since.

    @jimfl I've had issues with Erlang on macOS where I've needed to explicitly listen on IPv4 and IPv6 separately otherwise things fail to connect. I wonder if this is a similar problem...?

    rogerlipscombe,

    @jimfl the DNS implementation on macOS has always been a bit flaky.

    Returning NXDOMAIN for "localhost"? Go home, macOS, you're drunk.

    I'm fairly sure I'm good but just checking: is there any reason to censor a Wireshark stream of what happens when plugging in my home computer?

    My reasoning is that anything that matters should be encrypted with TLS or other, that the LAN addresses are useless, and I'm even okay with my public IPv4/IPv6 addresses leaking.

    With that in mind.. can you think of anything else that shouldn't end up on the YouTubes?

    rogerlipscombe,
    @rogerlipscombe@hachyderm.io avatar

    @fasterthanlime I did a Wireshark mini-tutorial at work a few weeks ago.

    I considered doing the captures on a completely fresh computer/VM, just in case.

    That phenomenon where you have a compile error, or a software bug, and when you fix it it turns out there was another one hiding behind it, and so on. And you don't find out what each failure is until you've fixed the previous one, so it's hard to tell in advance how many more problems you'll have to fix until it's working.

    It just struck me that a nice snappy description of the phenomenon is: "Error messages ride in single file, to hide their numbers."

    rogerlipscombe,
    @rogerlipscombe@hachyderm.io avatar

    @simontatham or the opposite, when you try to reproduce a bug, and several other bugs (that you've never seen before) jump in front of the one you're interested in.

    Once, a long time ago, I was sent to a conference about High-Frequency Trading. The buzz at the time was accurately measuring microsecond latencies.

    I was asked what we used. My reply was something like: "we deal in physical, delivered, commodities; a calendar is generally good enough".

    @jimfl @nicd this is basically what the different function clauses will compile down to, so they're equivalent.

    I suspect (but haven't checked) that the binary prefix matching would also be more performant than calls to String.starts_with?
