This is the most fabulous tree that I see every day. I have other favourite trees elsewhere, but this is amazing.
Also, less fabulous, this is where I sit to practice glyph hacking .

I'd resigned myself to being badgeblocked at L12, but by recharging resonators over the ocean, weirdly levelled up on the school run.
I hope none of this means anything to you. #ingress

Comet 12P Pons-Brooks is now a naked eye object, if you can see it through all of the Starlink satellites. Photo by Richard Schrantz in Nicholasville, KY USA. Schrantz writes: "I tried to image comet 12P Pons-Brooks on 3/28/24. Even though the field of view is just 1.75 degrees wide, I was carpet-bombed by satellites! This represents only 25 minutes of exposure. Thanks Starlink (and/or other satellites). Sheesh. Epsilon 180 ED, ST10XME camera."

@j_bertolotti @elaterite I'll try to get one - was discussed at KTN photonics meeting a couple of weeks ago. I'm away from machines right now.

HIVE MIND and also maybe BRITISH HIVE MIND, here is what I need, should you have any faves to proffer:

Obscure but hilarious British tv comedies that lasted 1-3 seasons and nobody could be bothered to pick them up for streaming except some dank corner of the streaming universe, like Roku Channel or whatev.

CRITERIA:

  • preferably TVMA or 16+
  • No laugh-tracks (this disqualifies most shows from being good and, frankly, is distracting and archaic and condescending as fuck)
  • not super-popular (basically if it's like Fleabag or Green Wing and on a mainstream streaming service and internationally recognized as brilliant, I will pretty likely have seen it
  • made roughly 2008ish to present
  • has NOTHING WHATSOEVER to do with Ricky Gervais
  • narrative storytelling e.g. NOT faux-documentary

As some guidance, here are shows of the ilk I am in the market for (and thus have already seen [AND RECOMMEND]):

Plebs
Bluestone 42
Crazyhead
Porters
London Irish
Toast of London
Zomboat
Cockroaches
Fresh Meat
White Van Man
Time Wasters
Back
Upstart Crow
Sirens
Raised by Wolves
Detectorists
The Bleak Old Shop of Stuff

Any suggestions welcome and thank you! ๐Ÿป

My approach for Advent of Code this year is to always try the simplest option first, even if it seems inefficient. It's much easier to write and debug 'find all possibilities, then filter' than 'find the filtered ones in a single step'. If you really want performance you can probably split up the possibilities and filter 1/X of them in X threads or something.

bocs,
@bocs@toot.wales avatar

@pwaring hard agree! I make a pretty complete data model even if it doesn't need to keep everything, or be indexed, or whatever. More than once this year it's paid off. I always parse all the input and stash it in the model before doing anything problem specific. Yes, it's inefficient and requires at least one more loop and more memory than necessary, but simple and naรฏve suits me ;)
(I do sometimes improve it later).
Next year, improved code will be much easier to understand and reuse.

Due to a heavy cold, I took a few days off from .

I finished some tasks, all days until 12, the 15th and first parts of 13 and 14.

13 A drove me mad! ๐Ÿคฌ

I found 3 patterns to have 2 solutions instead of 1 (painfully checked by hand: true!).

So: what to do?

I tried:

  • Leaving out ambiguous solutions.
  • Adding the results from both
  • Every possible combination of solutions.

In the end: One of the combinations worked!

In my view, the data was poorly designed.

@mina One of the interesting side effects of thousands of us all doing the same thing is that it really highlights how different people think differently. Some days look impossible but can be broken down logically. Others look impossible and require kind of next-level insight or imagination. 1/2

bocs,
@bocs@toot.wales avatar

@mina Others look annoying but mechanically tractable. A few look easy. They all need mapping onto algorithms which comes more easily with experience and familiarity with languages and libraries and environments, none of which I have.
I looked at some of your solutions last week and still don't understand them!
Conversely, 13 just worked for me.
People are all different and all awesome. Hope your cold has gone!

That's the only time, ever (including the future), that i'll do part 2 using only 8 characters more than part 1.

started very late with day 3; works fine on examples, fails on real. i'm almost at the point of printing the input and manually looking for what's breaking it. not a good look on day 3 ๐Ÿ˜ฎ

Slightly worried that day 2 was easier than day 1, kinda feel like tomorrow might be horrible.

For the first day of living in UTC+0, I actually have to be up at stupid o'clock anyway. In the interests of speed, which I usually do not care about, given the opportunity I shall start day 1 in in which the thing will take moments. I'll clean it up into because, well, one ought to. I'll then start again in because that's what I want to learn this time around.
I see a lot of exotic things, or rust, or R. Where's my perl tribesfolk?!

Right. Does peeling (not eating) a grapefruit make anyone else's tongue go completely numb or am I an alien. There's some freakass chemicals in grapefruit exoskeletons, which I assume get sprayed at attackers, for the very purpose of defense.
Good to know, either way. Ta.

It just amazes me that people keep expecting me to fly all over the place for conferences and seminar lectures. I've gotten uninvited to 2 conferences in the last couple weeks by politely asking if I could give the invited talk remotely instead. This is dumb, we need to change.

bocs,
@bocs@toot.wales avatar

@sundogplanets you know you're allowed just to say no anyway? One of the main things I've come to realise over last 5 years or so is just how messed up the whole industry of conferences is.

It's only 8pm and all my lecture stuff is prepped for tomorrow (I think). I don't have anything prepped beyond tomorrow, but THAT'S OK. I'm actually really looking forward to teaching, it's just a crapton of work... I wonder what weird school-related stress dreams I'll have tonight?

@sundogplanets writing and delivering a new course was one of the hardest things I've done. About 8 hours work for 1 hour of delivery, with 4 hours of delivery a week. And it wasn't my actual job. With the creation time, students were paid more to be there than I was to write and deliver. Good luck!

TIL; ingress is still very much still going and seems to be still excellent. Hard to believe an app for a location based game is still going a decade after I played, when all of the technology involved has moved forwards doing it's Moore's Law thing.
So now I shall be basing all my exercise around capturing portals. I may be some time. #ingress

I had to find a couple of papers for one of my students to review and I just looked at all the new papers on satellite observations and predictions for satellite pollution and now I am super depressed.

What's currently playing out in Low Earth Orbit is the worst parts of capitalism, on fast-forward (literally at several km/s if you want to get technical...) It's so bad. Orbit needs strong, international regulation 20 years ago.

Equations like this are why I do brute-force modelling of orbits most of the time rather than pencil-and-paper theory. Yikes. (Although I used this equation in my PhD thesis so apparently I knew how to deal with this ~10 years ago...)

@sundogplanets I like how the other multiples of the angles were deemed unhelpful and their coefficients have sulked off to the corner of a dingy pub to bemoan becoming negligible.
