This morning we went out to see whether there was a cat, there wasn't (he was at the neighbors), but there was a package that had evidently been delivered with the cat's signature.
There were very little indication on who the seller was, which meant I knew who the seller was, so, #unboxing time?
Contrary to what people here may expect from the unmarked box it's not an adult toy, but it's definitely a toy for adults, or at least it requires adult supervision for assembly and contains small pieces not suitable for children under 3 :D
@s1m0n4 un badge, tipo quelli degli hacker camp, ma più semplice perché non sono capace :) basato sul logo del fediverso
nel prossimo post stanno arrivando le foto del badge popolato con un po' di dettagli
@s1m0n4 potenzialmente tutte quante, con dei limiti e a seconda di quanto ci si voglia sbattere.
L'esp32-c3 è un microcontrollore, non un computer su cui gira linux, ma ci girano micropython e circuitpython, per cui programmarlo è facile, e ha una radio che fornisce connettività wifi e bluetooth (BLE).
La cosa più semplice di tutte è giocare coi LED e col bottone, ed è la prima cosa che farò, autocontenuto, di sicuro effetto :D
Un'altra cosa abbastanza semplice è farlo parlare con un server, mandare cose e ricevere comandi. Qui la difficoltà è decidere cosa fargli mandare e che comandi ricevere :)
Potenzialmente si dovrebbe poter anche comunicare in modo mesh tra i vari badge, ed è una cosa che sul lungo termine vorrei fare, ma lì devo avere tempo di vedere un po' di cose che non ho mai visto, quindi non ci sarà niente di pronto a breve termine, ecco.
And here it is! (or at least here the first two are)
This afternoon was spent soldering (badly), and I can confirm that after a couple fixes it's working!
And now, it's time to write software!
(also, to populate a few more badges for some friends at the LUG, but that can wait until I'm going to see them next time)
ed eccolo qui! (o almeno ecco qui i primi due)
Il pomeriggio è stato passato saldando (male), e posso confermare che dopo un paio di pezze funziona!
E adesso, è ora di scrivere il software!
(e anche di popolare qualche altro badge per degli amici al LUG, ma quello può aspettare la prossima volta in cui li si vede di persona)
And I almost forgot:
git.trueelena.org/electronics/…
(and I've just realized that it's still missing a license. it will be something free and reciprocal, I still have to decide what is more suitable)
e mi stavo quasi dimenticando:
git.trueelena.org/electronics/…
(e mi sono appena resa conto che manca ancora la licenza: sarà qualcosa di libero e reciproco, ma devo ancora decidere quale sia la più adatta)
btw, does anybody here on fedi have any experience with soldering bare #WS2812 / #SK6812 / #neopixels with a soldering iron?
the packaging was pretty scary on expiration dates, saying that once the seal had been opened everything had to be used in 24 hours, or go through a baking process, because of moisture sensitivity.
However, it also mentioned “reflow solder or other high temperature process”: does anybody know whether would it be safe to solder them with a soldering iron after some time in non-actively-dried storage?
qualcuno qui sul fediverso per caso ha esperienza nel saldare WS2812 / SK6812 / neopixels conn un saldatore?
il pacchetto faceva abbastanza terrorismo sul fatto che una volta aperto il sigillo andavano usati tutti entro 24 ore o sottoposti ad un processo di asciugatura prima di usarli.
Però parlava anche di “reflow solder or other high temperature process”: qualcuno sa se i problemi ci sono anche se li si salda col saldatore dopo che sono stati conservati in un ambiente non attivamente deumificato?
@Beko Pharm I don't have condensation dropping down from the ceiling, but I don't have the < 10% humidity mentioned on the package either.
At the moment I have used 10 LEDs out of a package of 20, and I'm going to try storing the 10 remaining ones and then try to solder them later, maybe at two different times.
I'm a bit more hesitant to open the 50 LED package, however :)
keep them in an airtight bag with desiccant and they will be fine to hand-solder whenever you get to them in future.
In short, yes MSL is definitely a thing, and good* vendors will pop a humidity indicator card into the pack so you know if they are ready to go as soon as you receive them or not. The issue is that many plastics are hydrophilic (they like to absorb moisture from the air), especially the plastics used in LEDs. When “wet” plastic is exposed to the 260°C ambient temperature of a reflow oven, the moisture can’t evaporate quickly enough so it turns to steam and builds pressure inside plastic packages which can make them explode.
Hand-soldering is usually fine because you don’t heat the entire package, only the leads, and you should only need a couple of seconds of heating to solder the joint instead of a typical 5 minute reflow cycle
@I love this, so I thanks! that's what was felt plausible, but also I was afraid to hope :)
There was indeed an indicator card (and dessicant) in the bag, and the leftover LEDs have been put back into it, and closed with some tape, I guess put the bag into a zip bag with some extra dessicant just to be sure. I assume that the indicator bag will say that they have been exposed to humidity the next time I'll open the bag, but then I don't have a reflow oven (and I'll avoid using the hot air station just to be sure) :D

I have used vim since around 2000. I have written five books, a PhD thesis, a few dozen papers and over 150 articles with it. At this point, my higher brain functions are not engaged at all when I use a bunch of common vim commands, they just happen. Documents I wrote with anything else have random :w in the middle.
So I tried NeoVim when it was quite new. Vim that you are familiar with, but better? Great!
Persistent undo is one of my favourite features of vim (introduced a few years after I started using it). My .vimrc includes a couple of lines related to this. One sets the path to be under ~/.cache so the undo files do not clutter the rest of the filesystem (I do the same for the swap files). The other sets the undo limit to something large (10,000, I think) because disk space is enormous relative to pretty much anything involving human-readable quantities of plain text.
I don’t often need the persistent undo. But on the few occasions when I have needed it, it’s been invaluable: ooops, I deleted something from this file, maybe last week and one reboot ago, what was it? Undo until I find it, copy it, paste it into the current version. Or, a bit more commonly: I had this working, then I tidied it up ready to commit, now it isn’t working, what did I do?
Vim has kept this working across major version upgrades over a period of about 20 years. I don’t even think about it, it’s just part of Raskin’s First Law: A program may not harm a user’s data or, through inaction, allow a user’s data to come to harm. If vim or the computer crash, or if I close a file and come back to it six months later, my undo history is still there.
The first thing I noticed in NeoVim was that undo didn’t work. I tried opening the file in vim and undo didn’t work there either.
Neovim had changed the format of the undo files. It hadn’t upgraded the old one. It hadn’t used a different name for its undo files. It had just noticed the existence of a vim undo file, deleted it (losing all of the data in it) and replaced it with one that vim couldn’t read.
I raised an issue about this and was told that the persistent undo format was unstable and users should not rely on data being preserved in a feature explicitly called persistent undo. It had changed once and would probably change again.
And that ended my experience with NeoVim. The authors showed immediately that they absolutely could not be trusted with any of my data. Breaking persistent undo is something I could forgive as a bug, but the attitude that just because something is a persistent file on your filesystem that contains data that you might want is no reason for their program not to delete it meant they had no concept of a duty of care to their users.
Apparently now they’re platforming white supremacists. I am completely unsurprised. Different facets of the same underlying attitude.

"My favorite thing about The Odyssey is that when you notice how the poem is structured, the whole thing starts looking like Odysseus is just making up an alibi after coming home from a 10-year Fuckboy Tour of the Mediterranean.
See, the parts of The Odyssey that Homer narrates directly are surprisingly grounded. At the beginning we see Ithaca, Telemachus travels around looking for news of his father, and so on. At the end Odysseus returns, kills the suitors, and everyone is happy (except for the suitors). The gods interfere constantly because this is ancient Greece, but mostly it's a story about people doing people shit just like The Iliad.
But in the middle section, the narration very conspicuously shifts from Homer to Odysseus himself. He's explaining to the Phaeacians why it took him ten years to sail home from Troy, and suddenly we're dealing with one-eyed giants, cannibal armies, a witch who turns men into pigs, magic bags full of wind, six-headed sea monsters, and a trip to the Underworld.
Odysseus tells his story to the Phaeacians while he is stranded, broke, and in desperate need of a ship home. And remember that Odysseus is not merely capable of lying – lying is basically his superpower. He routinely invents elaborate fake biographies for himself at the drop of a hat, to the point that even Athena is impressed with his capacity for deception. He is canonically the original male manipulator.
And it makes sense why Homer depicts Odysseus telling all of this to the Phaeacians instead of the much-less-gullible Penelope, since you can imagine how his story would have gone over with her:
"Odysseus, the Trojan War ended 10 years ago. Where have you been all this time?"
"See what had happened was, we were gonna come straight home – but then when we were in sight of Ithaca, my men opened this magic bag of wind while I was asleep and it blew us to the other side of the ocean."
"Why did they open the bag after you told them not to?"
"Ah, well, see, I sort of forgot."
"Your men all died because you had a magic bag of wind that you forgot to tell them not to open and then took a nap?"
"No, they were all fine! But see, then a cyclops and some giant cannibals killed most of the men, and a witch turned the rest into pigs. But don't worry, they got better."
"They got better?"
"Well sure, the witch changed them back after I slept with her."
"...I see. Well, I suppose you had to save your men."
"Exactly! And so after a year with her-"
"You slept with her for A YEAR?"
"Hermes told me to, baby!"
"The god Hermes told you to fuck another woman. For a year."
"Penelope, who am I to question the will of the gods? So then we went to the Underworld, and after a quick detour back to see Circe again-"
"YOU WENT BACK?"
"It was important, babe! She had to tell us how to avoid all the sea monsters!"
"The sea monsters."
"Oh, sure – loads of sea monsters out there. The sea is lousy with monsters these days."
"Uh huh. And did you sleep with her again?"
"I mean, it would have been rude not to..."
"ODYSSEUS."
"Will of the gods, baby, will of the gods! So anyway we're headed home for real this time, but the men ignored my extremely excellent advice and ate one of Helios' sacred cattle while I was asleep, and Zeus killed them all. Damndest thing. So I wash up naked on this beach with a beautiful nymph, and well, one thing kinda led to another..."
"Did you sleep with her for a year too?"
"Of course not!"
"Well, that's a relief."
"It was seven."
"SEVEN?"
"She bewitched me! I was bewitched! Can't fault a guy for what he does when he's bewitched, can you?"
"And did you meet any other women on this epic journey of yours?"
"Well, there was this teenage princess..."
"ODYSSEUS!"
"Nothing happened, babe, I swear! I just washed up naked on the beach right in front of her. Nice girl, you'd like her."
"Odysseus, this is the second time you've just happened to wash up naked on a beach right in front of a beautiful woman."
"I know! Crazy, right? Anyway, when I told her parents everything that had happened, they were so amazed that they gave me all this gold and a ride straight home so I could be with my beloved."
"After 10 years."
"Well yeah, straight home after 10 years. Don't forget the sea monsters, babe!"
"The sea monsters that you are conveniently the only person left alive to have witnessed."
"I don't love where you're going with that..."
"Odysseus, do you know what I did while you were gone?"
"...Waited faithfully for me?"
"I raised your son, ran your kingdom, kept a hundred men from taking your throne, and spent three years weaving and unweaving the same fucking burial shroud every night to keep them off my back."
"That's... actually very clever."
"Thank you."
"You know, between the two of us, that's really more my–"
"Finish that sentence and I'm sending you back to the Cyclops."

Stamattina siamo usciti a vedere se c'era un gatto, non c'era (era dai vicini), ma c'era un pacchetto che evidentemente era stato consegnato facendo firmare al gatto.
Sul pacchetto c'erano pochissime indicazioni di chi fosse il venditore, quindi ho riconosciuto chi fosse il venditore, quindi è il momento per un unboxing?
Contrariamente a quello che certa gente qui potrebbe pensare vedendo la scatola anonima non è un prodotto per adulti, ma è decisamente un giocattolo per adulti, o quantomeno richiede la supervisione di un adulto per l'assemblaggio, e contiene parti piccole non adatte a bambini sotto i 3 anni. :D
