mh (ADHD) alc

So, the one advantage to being out of ADHD meds is that I can have a drink without worrying about drug interactions.

I'll take my victories where I can.



Okay, sqlitebrowser (from the #Debian repositories) is actually a pretty decent tool. It provides a nice point-and-click interface that makes working with #sqlite3 databases a little bit nicer. Knowledge of how to write an #SQL query is still a requirement, but it makes creating/editing tables more convenient. Maybe it's well known, but I just discovered it yesterday.

Edit: sqlite browser, not mysqlbrowser

So, I get that #KiCad can't have symbols and footprints for every component ever in their default library, but some of the things they've chosen to include can be a little confusing when compared against what they haven't chosen to include. Here's an example:

There are symbols for the TC74HC00 (quad NAND gate) and TC74HC08 (six channel inverter) series of chips, but none for the TC74HC04 (quad AND gate). Sure, the 74HC00 symbol can fairly trivially be edited into a 74HC04, but still... Am I missing something here?

Fortunately, for this particular board I was able to do some boolean magic with a single 74HC00, so it's a moot point.

@cpresser That sounds about the right time frame. We'll see who's done first. ;)


electronics question

I'd try this out on a breadboard, but I don't currently have the necessary parts so I'll just ask instead.

What happens on a 555 timer if you simultaneously drive the trigger low and the threshold high? Is this an error state that could vary from chip to chip?

My guess is that the output would be driven low, but that the drain would remain in a high-impedence state (as I'd expect both the Q and ~Q outputs of the SR latch to be driven low.

@Matthew Skala Fun fact: I was staring at that exact data sheet and didn't see that. I've no plans to do this. I was just curious. Thanks for pointing it out though.


Woo! Got my clock module down to two chips total (plus resistors, capacitors, and such).

Really basic stuff, but I'm still learning #KiCad.

Just realized the the current design won't honour the halt signal when it's in manual pulse mode... πŸ™
in reply to Jonathan Lamothe

Aha! A hacky solution, but I can fix it by wiring the switch that sends the manual clock pulse to ~HLT instead of +5V. No additional logic gates required.




Decided to look into Nostr since everyone here seems to hate it (so I can figure out why).

From their website, they tout that it's "censorship-resistant"* while also complaining that traditional social media is overrun by bots and spam.

How does one go about solving the bot/spam problem without resorting to censorship? This feels rather mutually exclusive to me.

* frequently a fascist dog whistle

in reply to Jonathan Lamothe

coincidently heard about nostr for the first time today and the context was "noted fascist network nostr" or words to that effect
in reply to Jonathan Lamothe

I haven't bothered to check it out yet. I quite like Scuttlebutt, which Nostr is somewhat based on, but Nostr lacks the features that make Scuttlebutt actually nice to use.





So, last I checked you could still buy PCB mountable sockets for them, bit does anyone know if anyone's still manufacturing NES-compatible controllers?
in reply to Jonathan Lamothe

retrobit still sells an nes compatible controller, kind of a clone of the nes advantage.
8bitdo makes bluetooth receivers that plug into an nes controller port, been thinking about getting one of those.
And there are plenty of no name 3rd party nes controllers on websites like aliexpress
in reply to Jonathan Lamothe

Sure looks like it. A quick search comes up with cheap clones, as well as "new" designs like Hyperkin Cadet.


Say what you will about modern #AI chatbots, but we've given them the ability to suffer from Dunning-Kruger. That's something... right?
#AI



Here's the funny thing about propaganda:

It gets started by someone (or a group of someones) with an agenda, but when it's effective, it gets swallowed and spread by well-meaning individuals who simply don't know any better. When this happens, it becomes even more effective, making it a vicious cycle.

Not everyone who spreads it is doing so for nefarious reasons (though many are).

...and I've officially let myself run out of my ADHD meds.

Shit.



How did I ever live before terminal multiplexing? Decided to work out on the balcony this morning, and then when the weather changed, was able to just hand off my various SSH sessions from my tablet to my laptop.
in reply to Jonathan Lamothe

Which multiplexer do you use? I've been wanting to get better with that. I've played around with screen and tmux a bit, but need to get more fluent with the commands/shortcuts.
in reply to Hrrmmph

@Spacegoat I used screen for many years. I somewhat recently switched to tmux. Both are solid options, though tmux seems more popular.


Why am I suddenly getting fundraising emails purporting to be from JoeBiden.com?


Encountered a hiccup during the daily backup of the server. Working on restoring. No data loss is expected.








Still having some stability issues. I've tweaked some settings on the database to try to alleviate the congestion.
