Turns out I was storing multiple (10+) gigabytes of internal data from the ventilation system including fan speeds, system humidity and temperatures, etc as it is one of the most aggressively real time systems connected to the automation.

Oops?

So I noticed yesterday that my home automation server (surprisingly useful when you have solar panels) was running out of storage space, and thought I was going to have to buy more.

Then I noticed that I'd stored every change in fan speed of the ventilation system for the past 18 months because I'd forgotten to add a retention policy.

I've been very impressed with the collaborative editing support built into CodeMirror. There's certain properties in software that still always feel magical to me, and shared code editing is very much one of them - watching changes made by other people spread around the world appearing in front of your eyes is still just awesome, even if I do know how the magic is happening behind the scenes.

We had to page requests to one of the SOAP APIs because if you asked for too many customer details at once, you got back malformed xml ending with -- more --

@[email protected] This is a really clear explanation that I've sometimes missed in the past. Thank you for making it happen!​

@[email protected] ​The only unfortunate issue with that is that it involves going to shops; the kind of things that I'd buy from the shops I'd like to visit (board games, books, etc) are pretty easy to order reliably online (and there aren't many local options), while the things that can't reliably be bought online tend to be in shops that are a full on sensory assault.

Both of these things make me sad.

@[email protected] ​Sort of related to this: I've taught professional developers (who had been taught recursion is potentially dangerous and hard to reason about) recursive coding techniques, and I have taught multiple 10-12 year old kids how to use recursion.

The two groups find this specific aspect of coding about equally easy to learn despite the much broader capabilities of the "professionals" in general (explaining why .NET APIs are built of classes with interfaces to 10-12 year olds is a whole other challenge).

(Obviously there are also many professional devs who weren't taught that recursion was a Dangerous Evil to Be Avoided™, but that's not the point here)

@[email protected] ​I'm with @[email protected] here - ten years ago when I first heard it, it seemed catchy and came with good enough advice I liked it. The more I've thought about it since, the more I've decided it is actually quite harmful in it's imprecision. A strong like, weakly held, I suppose...

I missed it at the time, but someone recently pointed me to this Stephen Collins comic which is both brilliant and also perfectly captures a lot of what is broken in the current usability of technology. Assumed meanings, performative "checks", etc.

@[email protected] @[email protected] I love good game system design in the way I love a good board game, or a good programming language, but in terms of actually running #ttrpg I feel like I notice bad system aspects much more than I appreciate good system design.

Like... hit points and falling damage; if the character knows in universe that they can jump off a ten story building and brush it off but the universe doesn't "feel" like that should happen, that's an issue.

But clunkly, awkward, weird systems? Honestly they seem to fade pretty quickly into the background as long as they don't break the universe.​

@[email protected] "I don't understand it" <- I think this is what makes it so hard. I don't understand my own task avoidance even when it's happening; I mean sometimes I just get lost, but sometimes I'll be sitting there feeling miserable and not understanding why I can't just get up and do the thing. I'm slowly learning to recognise more realistically when I can and can't do things, and on a good day feel less guilty about the "can't" - but as to why? Often it just feels so stupid.

@[email protected] @[email protected] ​That was really helpful!

Unfortunately, since then I've mainly seen it used as an excuse for loud voices to drown out the quiet ("well, if I can't state this opinion forcefully it's not a real conversation") or to justify a lack of due diligence/research ("well, I have a gut feel so I'll just go for that strongly until someone else does the work to point out why it's a really stupid idea - but it was weakly held so I don't need to feel any guilt!")

@[email protected] @[email protected] I have some history with this phrase...

It was first explained to me in the context of being a Brit working in a US company for the first time, where my new manager mentioned that I was putting forward good ideas in a tone that to Americans sounded like I didn't believe in them. His comment was that it was better to state an opinion clearly and without excessive caveats and let it stand and fall on its merits, being willing to give way if you were convinced by the feedback that it wasn't the best option.​

After a discussion on here recently about chat services allowing your local nicknames to override people's display names, I was amused this morning to see "Admin Mum deleted this message" in a chatroom where my mum happens to be a moderator but isn't just for our family.

Apart from a moment of double take, it also struck me as the kind of super hero the world needs sometimes. "Admin Mum; overcoming bureaucracy for a better world!"

My Ink support in CodeMirror is now in its own project separate from @VisualInk , meaning it can be easily used in other JavaScript projects.

@[email protected] the scary thing about this framing is that it rather highlights the fact that security issues don't tend to have (short term) cash flow implications, while downtime incidents do.
