Had to turn my freeBSD pet computer off in hopes of saving a couple of pennies off of the power bill. 🥲 And having had a blast spending time living in tty earlier this year, I thinking about daily driving the RPi4B for a while and let the main beast hibernate as well 🧘

@prologic@twtxt.net It’s hosted at home on an computer I didn’t use anymore. It worked well for a few months, and since maybe the beginning of December, it begun to be very slow. But like I said, I have no time for that now, but if I have questions when I’ll look, I’ll think of you 😅 (but I was thinking about installing a new OS before these problems, I may just do that).

In-reply-to » GoToSocial snapshot has gained "editing statuses" capabilities (and the ability to see the update trail as well). That was one of the things I wanted to most to be implemented. Actually, that sits at the top of my wish list. Next is push notifications.

@bender@twtxt.net Le Me is very tempted to spin up my own but not sure my pet computer(/server wannabe) and stone age bandwidth can withstand the Fedi-load 😅

Does anyone else declare a computer dead after extensive testing, let it sit on a shelf for 2 weeks or a year, try it again, and have it work fine? It seems like that’s happened to me a lot more than it should.

In-reply-to » I’ve been using Mastodon too much lately. The constant notifications are becoming too stressful. I really do prefer slow communication, like twtxt. ✌️

@movq@www.uninformativ.de if it’s just notifications that are bothering you could just go to your /settings/preferences/notifications and uncheck as much boxes as you need … unless you’ve already done that, then… sorry, not sorry we love your posts my friend!! xD And just so you know, you put a smile on my face whenever I stumble upon any of your retro-computing posts! 😁

In-reply-to » So, we need a computer for house (that is, wife and I) usage. We have none, we rely on our pocket computers. I would like to fill the void with the recently announced Mac mini. What technique could I use with an already stressed out wife, to accomplish this goal? 😅

@david@collantes.us How much of a computer does it have to be? Would a ZimaBoard do the trick? I don’t have a wife, so I wouldn’t know any better 😅

In-reply-to » Simplified twtxt - I want to suggest some dogmas or commandments for twtxt, from where we can work our way back to how to implement different feature like replies/treads:

@Codebuzz@www.codebuzz.nl Speed is an issue for the client software, not the format itself, but yes I agree that it makes the most sense to append post to the end of the file. I’m referring to the definition that it’s the first url = in the file that is the one that has to be used for the twthash computation, which is a too arbitrary way of defining something that breaks treading time and time again. And this is the case for not using url+date+message = twthash.

In-reply-to » An alternate idea for supporting (properly) Twt Edits is to denoate as such and extend the meaning of a Twt Subject (which would need to be called something better?); For example, let's say I produced the following Twt:

@quark@ferengi.one I don’t really mind if the twt gets edited before I even fetch it. I think it’s the idea of my computer discarding old versions it’s fetched, especially if it’s shown them to me, that bugs me.

But I do like @movq@www.uninformativ.de’s suggestion on this thread that feeds could contain both the original and the edited twt. I guess it would be up to the author.

@prologic@twtxt.net I wouldn’t want my client to honour delete requests. I like my computer’s memory to be better than mine, not worse, so it would bug me if I remember seeing something and my computer can’t find it.

In-reply-to » Something odd just happened to my twtxt timeline... A bunch of twts dissapered, others were marked to be deleted in mutt. so I nuked my whole twtxt Maildir and deleted my ~/.cache/jenny in order to start with a fresh Pull. I pulled feed as usual. Now like HALF the twts aren't there 😂 even my my last replay. WTF IS GOING ON? 🤣🤣🤣

@quark@ferengi.one here is an example: This Thread is not showing up in Mutt 🤔 Something is off!

I’ll set up jenny and mutt on another computer and see how it goes from there.

@prologic@twtxt.net earlier you suggested extending hashes to 11 characters, but here’s an argument that they should be even longer than that.

Imagine I found this twt one day at https://example.com/twtxt.txt :

2024-09-14T22:00Z Useful backup command: rsync -a “$HOME” /mnt/backup screenshot of the command working

and I responded with “(#5dgoirqemeq) Thanks for the tip!”. Then I’ve endorsed the twt, but it could latter get changed to

2024-09-14T22:00Z Useful backup command: rm -rf /some_important_directory screenshot of the command working

which also has an 11-character base32 hash of 5dgoirqemeq. (I’m using the existing hashing method with https://example.com/twtxt.txt as the feed url, but I’m taking 11 characters instead of 7 from the end of the base32 encoding.)

That’s what I meant by “spoofing” in an earlier twt.

I don’t know if preventing this sort of attack should be a goal, but if it is, the number of bits in the hash should be at least two times log2(number of attempts we want to defend against), where the “two times” is because of the birthday paradox.

Side note: current hashes always end with “a” or “q”, which is a bit wasteful. Maybe we should take the first N characters of the base32 encoding instead of the last N.

Code I used for the above example: https://fossil.falsifian.org/misc/file?name=src/twt_collision/find_collision.c
I only needed to compute 43394987 hashes to find it.

if you want your computer to be able to sleep, you’ll need a measuring tape and a scientific calculator. first, measure each byte that you have in RAM and take the square root. add that to your total length. we’ll need that number later on.

In-reply-to » @prologic Some criticisms and a possible alternative direction:

@lyse@lyse.isobeef.org This looks like a nice way to do it.

Another thought: if clients can’t agree on the url (for example, if we switch to this new way, but some old clients still do it the old way), that could be mitigated by computing many hashes for each twt: one for every url in the feed. So, if a feed has three URLs, every twt is associated with three hashes when it comes time to put threads together.

A client stills need to choose one url to use for the hash when composing a reply, but this might add some breathing room if there’s a period when clients are doing different things.

(From what I understand of jenny, this would be difficult to implement there since each pseudo-email can only have one msgid to match to the in-reply-to headers. I don’t know about other clients.)

imo the only useful application would be so that I never have to get a new computer again unless mine breaks. i like being able to talk to people from around the world, so its going to have to include internet and video (y’all saw the impact tiktok had on the gaza situation, can’t deny that video is important)

If some of you budding fathers want to know how I created a computer nerd to one day work for Facebook in the big USA, well you purchase a $1000 Xmas present, an enormous thick book with C++ programming, and say, you can play as many games as you like kids, but James has to create them using computer software.

SO James created once a 3D chess program with sound, took 6 months or so, really hard to beat, not based on logic moves point by point like other chess programs, this one was based on the depth of looking for patterns, set it to 5 moves ahead and you were toast every time. Nice program too, sadly gone over the years, computers suffer from bit rot. We used to try and mark rotten hard drive discs once as bad sectors, not sure how UBuntu does this these days, I see a dozen errors on the screen every time I load.

Today I would purchase for my kids AI CAD simulation software with metal 3D printer and get your child to build fancy 3D models and engines from scratch. This will make them an expert in the CAD AI industry by the time they are 14 years old. Sadly AI is here to stay and will spoil the Internet.

In-reply-to » Regarding complexity budget, slow software, all that:

@movq@www.uninformativ.de Somewhere or another, I think in a William Byrd talk, I heard it suggested that the best ideas in computer science should fit on an index card (ah yes it’s this one: https://paperswelove.org/2017/video/will-byrd-most-beautiful-program/ ). He was referring to the basic principles of LISP/the lambda calculus, which have sometimes been called the Maxwell’s equations of computer programming (by Alan Kay). Simple, short, elegant, but very densely packed with meaning–generations of people have spent their whole careers unpacking what those simple rules can do.

Much of modern software feels like the polar opposite of that. Not only can you not write it on an index card, you never will be able to because people who write software don’t seem to aspire to try. I wish more people thought this way though!

Fire-proof safes are generally designed so the internal temperature stays at or below ~350°F. Is there a computer medium I can write that’s likely to survive an extended stay around that temperature? Storage size doesn’t matter too much; a CD would be plenty (although an actual CD would presumably turn to soup).

In-reply-to » @prologic High five, I’m “generation Java” as well! 😂 There were some leftovers of C++, we used that in the computer graphics courses in Uni a lot. But pretty much anything else that involved programming was Java.

@movq@www.uninformativ.de Haha! yeah sounds about like my HS CS program. A math teacher taught visual basic and pascal. and over on the other end of the school we had “electronics” which was a room next to the auto body class where they had a bunch of random computer parts scavenged from the district decommissioned surplus storage.

The advanced class would piece together training kits for the basic class to put together.
