Before we went to HD with Sonys, that Panasonic was THE camera for our production department. Cheap, lightweight, easy to use, fairly robust. King of the 'good enough'.

One neat idea psdoom allows for is making you work harder to kill a process that should be harder to kill - I don't remember what they scale by, probably runtime? It makes a certain kind of sense that it should be harder to kill a httpd that's been active for months than a grep -r you started 30 seconds ago, but nothing in the user interface of kill allows for that.

I think my issue with them is that they were created in a way where it was easy for some graybeard in the 70s to do something really fast so the command is just two characters and it has the ability to gently caress up your entire computer if you type the options wrong. So it feels like to move a file you have to type out a 130 character long command line with 20 options but if you want to delete the entire file system just type jkl in any terminal, no need to even press enter.

If they didn't they would suck The interesting UX discussion is that physical tools are not like that. Pulling nails and cutting wood and the like is, as a first approximation, harder for more structurally important parts of your house. Do we want CLI tools with similar mechanics? Probably not! That doesn't mean it we can't have fun wondering what that would look like - and psdoom comes up as one of the few examples of actually implementing it, even as a joke.

Well what I was about to add was that you can use a hammer to hit a nail or your 5 year old son can use it to smash a window. It doesn't have any built-in safeguards against the latter, and should it? Wouldn't that make it worse at hitting nails? Maybe today that's a wholly different conversation when hammers can have wifi and AI

Windows may be an expensive and annoying part to replace, but the roof won't fall on your head because a window pane broke. Hammers shouldn't have safeguards, but it is a natural side effect of their job that a roof truss is harder to cut than a skirting board, and a framing nail is harder to pull than a carpet tack. It's that "more important things are sturdier" effect that's lacking on the software side. There are ways we have tried to add some resistance later, like immutable files and even making parts of the system read-only. That helps, but I conceptually like the idea of a simple heuristic that makes more important things harder to break. Even if it wouldn't make any sense in practice.

Process killing difficulty thought experiment? I'll give it a shot! For something cli-compatible, killing a process also requires typing in a key akin to a password or hash. The key is in no way secret, it's shown in the process list/details, and also given a part of the error if you fail to kill a process correctly. It's randomly generated and refreshed every minute or so. The length of the key is determined by how long the process has been running, the character space is based on account context. Process started by same user the key is just numeric, process started by different user alphanumeric, system level or processes flagged as important include symbols

I guess I'd like to see more about the criteria for what should make a pid more difficult to kill. Why is it just the long-lived ones that should be tougher? Why wouldn't you ever expect to run into a situation where you want to kill the 3-month-old Apache process but not the new one you just spawned with a new config? I know for sure at least as often as not the process I want gone is the one that's been slowly leaking memory for a year and now I have to type in a 21-digit prime number? gently caress that I'll just reboot

Sad news today, after my newly ordered Toshiba T5200 spent three weeks circling in the mail due to some mislabeling, it finally arrived with a broken plasma screen. Replacements are not easy to find unless you want to spend $300+ from an industrial supplier, so time to watch for other options It's a real shame since the plasma display (and being more powerful/moddable than my T3100) is why I wanted it. The good news is I figured out how to switch it to external display so it's at least a 386 desktop for now. Particularly once I add sound/network and put in a new battery and a Gotek.

I’ve been trying to find the model of a laptop I used to have. It was the first computer that was ever “mine” as an 8yo kid, a hand-me-down or yard sale find or something like that. The one thing about it, which I have never seen before or since, was that the whole screen could be detached and driven by a single thick cable from the laptop. The back of this color LCD was removable, such that you could place the screen on an overhead projector to present your screen. I thought this would be easy to track down, but my googlings are turning up nothing. Does anyone remember these?

Yes! I want to say Texas Instruments? We had some of those in my elementary school, so naturally, my memory of them is foggy I thought they were the coolest things. The teacher could just plop them on the overhead and we could see what was going on. There were definitely some education-specific programs we were using with them E: maybe not. We had these: http://www.datamath.org/Graphing/TI-VSP82.htm and I assumed the cable was running to a separate PC, but I guess it’s just a power cable? They run off a calculator, which is why I only remember them being in math class I guess. When I was a kid I thought they were real computers.

It’s really driving me nuts that on top of not being able to find the specific model, there seems to be no googleable evidence of such a thing ever having existed. Mine? I got bored of solitaire and took it apart to see what’s inside, using a hammer and a flathead screwdriver

r u ready to WALK posted:https://www.youtube.com/watch?v=nduMTX86Zl0 I and several of my friends had a network where we'd install a new OS (don't remember the name now; this was over 20 years ago now) and trade games like Mario, Mega Man 83, etc. I'd occasionally write a text RPG for my friends in Basic. Lots of fun. Now those Ti-nspire calculators can emulate real Game Boy games, from what I've seen on YouTube.

My daughter is a high school junior and, while it is odd that graphing calculators haven't changed in the 26 years since I finished high school, I appreciate that I can pick up the calculator and quickly remember how to do things.

I spent much time bored in class trying to work out how to build a ti83 based network using the com port. I didn't know anything about network contention so it would have to be circuit switched. Could a z80 asm app have enough control over the com port to do something more interesting?

The good thing about graphing calculators is that they stay the same for decades. They just work, and last forever on their batteries, and don't require updates of any kind and certainly don't start updating themselves while switching around the locations of buttons or menu items. Instead of each couple of years having to deal with new app-related 'New and improved' bullshit on phones that may or may not work, or even be outlawed because of telephones in classrooms restrictions. Truly a tech relic, in the best of ways. The downside is that the cost is also a relic from the times that a calculator with a graphic display was something really special.

Dyscalculia is not fun so I didn't get very far with math, but I do remember the smarter kids having a program that looked like what the teacher would use to wipe the calculators so they could keep all of their games and pre-saved stuff for class.

Teachers were so busy trying in vain to prevent students from playing games or "cheating" with programs that they missed the fact that figuring out how to write a program to calculate the quadratic formula was clever and showed initiative and at least a degree of talent.
