A while ago on a whim, I did a somewhat deep dive into the abacus. I thought it would be interesting to learn about a device that is sometimes credited as an ancestor of the modern computer.
I've come to be of the opinion that it's not really a fair comparison though. An abacus is not a computer... at least not a full-fledged computer. It doesn't compute anything. Your brain does that. I think it is fair however to compare it to memory, though.
An abacus is essentially an array of memory cells. Instead of storing bytes, it stores digits, but that's a trivial distinction. You even have to allocate those memory cells to accommodate the structure of the data you are operating on, just like you would with the memory in a computer.

@RicoElectrico I'll second the recommendation on ESP32. I probably have 10 of them now and they are quite capable.
That said, the Pi Pico is decent too, especially if you have unusual high speed signaling requirements.
my current project is doing just that and with #esp32
[edit]This setup uses a handful of #esp8266 with sensors, all in a mesh with network, plus one esp32-c3 as the bridge to the normal home WiFi network, and a #RaspberryPi Zero for data storage

I buy from AdaFruit. Their boards are more powerful than the Arduino, and not as powerful as a Raspberry Pi.
If I need an operating system, I plug an AdaFruit board into a Raspberry Pi.
My most popular project in that area is: github.com/shapr/bloohm
GitHub - shapr/bloohm: visual bloom filter to display process status as neotrellis m4 output
visual bloom filter to display process status as neotrellis m4 output - shapr/bloohmGitHub
Arduino produces a range of boards, including ones that are far more powerful than the Uno.
I would recommend the Pi Pico though if you're looking for something faster than the Uno and still cheap. There's Arduino IDE support for them as well.
@xorbit I just started using one, a C6 (that’s what they had in stock in the shop where I was ordering the other stuff.)
I program it with the Arduino CLI, because that’s what I’m used to and I don’t want to learn another toolchain before I know if I need to. I’m impressed so far. The dev board is cheaper than an Arduino Nano, it has many features, WiFi, Bluetooth, Flash memory is very flexible.
depends on your use case. Pi and Arduino are extremely different beasts.
Do you need lots of GPIO? Network? Wi-Fi? Memory? Flash? Camera/LCD connections? Floating point or integer only? A multitasking OS (with X! and a GPU!), an RTOS, or bare metal? Interoperability with some ecosystem? With good community support or something raw that you can slog through in god-mode and never need to update?

That Mozilla thing makes me think of an effect I keep seeing that I tend to call inversion of expertise. I'm sure there's a better name that's already established, but that thing where a priority is set that's manifestly absurd, such that only people *without* the expertise to realize the absurdity get promoted into decision-making positions.
That then further erodes institutional capabilities, and makes it even harder to incorporate expertise.

I think that's because it's a confluence of factors? The market reacts to the hype, big companies react to the hype to increase their stock price and then look at each other like "oh crap, we have to keep going or our *competitors will win*", lather rinse repeat. I think there are decision makers that know it won't pan out at some places, but feel obligated to get in on the hype before the bubble pops.
Was the same way with Blockchain and dotcom (in bigger ways).

I'm sure it happens for other reasons, too, but in #uspol we see it because the person appointing / hiring has a position (political view) that does not reflect observed reality, such that people with sufficient expertise can't support that position and don't get hired / appointed.
I'm sure it happens all the time for more bureaucratic reasons to.. institutions are almost always incapable of winding down and ceasing operations, even when that would benefit the persons they serve.
@BoydStephenSmithJr @ShadSterling Kind of... that's the idea that someone is promoted because they are competent, but fail to be promoted once they reach the ceiling of their competence, ensuring that they eventually end up in a job for which they are definitionally unsuited.
What I'm pointing out differs in two ways: the promotions in this case are *because* they're incompetent, and I'm looking for the systemic consequences of that selection rather than the individual consequences.
My mother-in-law overestimates my command of the Spanish language (though knowing French is admittedly helpful).

Since I am not a dumbass, I know that it doesn't actually take $400,000,000 a year to develop a web browser. So since Mozilla gets at least that much EVERY FUCKING YEAR from one source out of the many they have available, why are they now asking for donations from me?
Perhaps it is time to get back to developing a web browser, rather than other things that aren't web browsers that you wish to stuff in my web browser in order to monetize me?
@.vad//hakara🧭 It turns out, making a web browser is more complicated than you would think.*
I doubt it costs $400,000,000, as you point out, but there's a reason there's so little competition in the market.
* Looking at the HTML5 spec, I can't escape the conclusion that this is by design.

I have a friend who is being harassed and threatened semi-anonymously via Facebook. She knows *who* it is, but Facebook and Police are characteristically being uselss.
I am kinda useless at this side of deanonymization, but does anyone have advice or resources for deanonymizing enough to get cops to move?

"Facebook" -- find the error.
The only valid advice is:
LEAVE F.C.BOOK for good.
that sounds like a horrible situation. I'm a little confused how she could be being harassed on FB if she's made her account Friends Only and then unfriended anyone who is nasty, though. You don't have to be wide open to the public, there (unless you are trying to run a business).
Locking her account down only addresses stopping that avenue for the harasser, though. It doesn't address getting the cops to handle threats. But is her harasser using multiple FB accounts?
@silverwizard Facebook requires users to use their legal name, so you can report any account with pseudonym and they have a chance to be locked until the user submits a government ID and their display name will be changed to what’s written on it.
It won’t directly address the harassment but it might help with the identification part of the police process.

if you can host a file on a site where you can look at the access logs and then post a link to that file, you might be able to bait them into downloading the file which could give you their IP address in the access logs. A whois search for the IP address.could get you their ISP and geolocation information on the IP could get you the general area.
That's a lot of "ifs" and "coulds", though.

from there, of the police still won't do something, it turns to filing court orders to get information from the IP holders about who had the IP at the time of access and harassment.

It should come as no surprise to anyone who's been paying attention that I've grown disillusioned with capitalism over the past several years. What's interesting to me though is that any time I express this publicly, there are no shortage of capitalists who falsely assert that I am claiming that communism is the ultimate solution to everything. This is a false dichotomy.

Just beautiful. Great reminder how pure and powerful Unix once was.
Thinking about it, my first serial-line terminal login on a SysV machine was back in January 1990, eons ago. It was a big tower case server with a 68020, and even then it was considered an older machine for legacy projects and unimportant enough to let newbs like me have a go at it. Your machine is about a generation or two older, and still running strong. Great job!
Hey #Unix folks recommend me your favorite games that can run in the terminal that aren't:
1) the most basic boring arcade stuff like snake or missile command
2) roguelikes/dungeon crawlers (love em but there's no lack of those)
3) chess, backgammon, etc., more meaty board games sure but there's already a million easy to find ways to play chess in a terminal
edit: 4) IF, I know where to find plenty of that, forgot this one
This is for my machine with no gui so when I say terminal I mean terminal not just like "text based and looks like it'd be in a terminal maybe".

in reply to publius • •@publius I did not know that. I did know that an earlier incarnation was basically a sandbox though (the so-called dust abacus). It was a box with a thin layer of sand that could be drawn on with your finger or a stick (like a chalk board).
Later iterations involved carving grooves into a hard material and placing stones in them. I imagine the tablecloth spawned from this idea perhaps? (Or maybe the other way around?)
It wasn't 'till later that someone had the idea to put a hole through the stones and thread a rod through them so you wouldn't lose them.
