@prologic@twtxt.net aha, thank you, that got me unjammed.

Turns out I thought I had an SSH key set up in github, but github didn’t agree with me. So, I re-added the key.

I also had to modify the command slightly to:

ssh -p 2222 -i PRIVATE_GITHUB_KEY GITHUB_USERNAME@cas.run help

since I generate app-specific keypairs and need to specify that for ssh and I haven’t configured it to magically choose the key so I have to specify it in the command line.

Anyhow, that did it. Thanks!

@prologic@twtxt.net so what is the command to use? I did ssh -p 2222 GITHUB_USERNAME@cas.run help but that gives the same error. There’s something missing here.

Since I administer bucci.onl myself, I’m a little confused. I don’t recall disconnecting myself from sending and receiving emails. I don’t even know how you disconnect someone from that. I also have never created the email address this email appears to be coming from, but maybe I should trust it anyway since they told me it’s a trusted source? Most puzzlingly, I’ve been sending and receiving emails just fine all morning, so I do not appear to be disconnected from anything?

@prologic@twtxt.net hmm, I’d be up for thinking about that. At least at the protocol and design level–I’m afraid I can’t help much with Go programming.

@prologic@twtxt.net I think those headsets were not particularly usable for things like web browsing because the resolution was too low, something like 1080p if I recall correctly. A very small screen at that resolution close to your eye is going to look grainy. You’d need 4k at least, I think, before you could realistically have text and stuff like that be zoomable and readable for low vision people. The hardware isn’t quite there yet, and the headsets that can do that kind of resolution are extremely expensive.

But yeah, even so I can imagine the metaverse wouldn’t be very helpful for low vision people as things stand today, even with higher resolution. I’ve played VR games and that was fine, but I’ve never tried to do work of any kind.

I guess where I’m coming from is that even though I’m low vision, I can work effectively on a modern OS because of the accessibility features. I also do a lot of crap like take pictures of things with my smartphone then zoom into the picture to see detail (like words on street signs) that my eyes can’t see normally. That feels very much like rudimentary augmented reality that an appropriately-designed headset could mostly automate. VR/AR/metaverse isn’t there yet, but it seems at least possible for the hardware and software to develop accessibility features that would make it workable for low vision people.

@stigatle@yarn.stigatle.no @prologic@twtxt.net @eldersnake@we.loveprivacy.club I love VR too, and I wonder a lot whether it can help people with accessibility challenges, like low vision.

But Meta’s approach from the beginning almost seemed like a joke? My first thought was “are they trolling us?” There’s open source metaverse software like Vircadia that looks better than Meta’s demos (avatars have legs in Vircadia, ffs) and can already do virtual co-working. Vircadia developers hold their meetings within Vircadia, and there are virtual whiteboards and walls where you can run video feeds, calendars and web browsers. What is Meta spending all that money doing, if their visuals look so weak, and their co-working affordances aren’t there?

On top of that, Meta didn’t seem to put any kind of effort into moderating the content. There are already stories of bad things happening in Horizon Worlds, like gangs forming and harassing people off of it. Imagine what that’d look like if 1 billion people were using it the way Meta says they want.

Then, there are plenty of technical challenges left, like people feeling motion sickness or disoriented after using a headset for a long period of time. I haven’t heard announcements from Meta that they’re working on these or have made any advances in these.

All around, it never sounded serious to me, despite how much money Meta seems to be throwing at it. For something with so much promise, and so many obvious challenges to attack first that Meta seems to be ignoring, what are they even doing?

👋 Q: How do we feel about forking the Twtxt spec into what we love and use today in Yarn.social in yarnd, tt, jenny, twtr and other clients? 🤔 Thinking about (and talking with @xuu@txt.sour.is on IRC) about the possibility of rewriting a completely new spec (no extensions). Proposed name yarn.txt or “Yarn”. Compatibility would remain with Twtxt in the sense that we wouldn’t break anything per se, but we’d divorce ourselves from Twtxt and be free to improve based on the needs of the community and not the ideals of those that don’t use, contribute in the first place or fixate on nostalgia (which doesn’t really help anyone).

On LinkedIn I see a lot of posts aimed at software developers along the lines of “If you’re not using these AI tools (X,Y,Z) you’re going to be left behind.”

Two things about that:

1. No you’re not. If you have good soft skills (good communication, show up on time, general time management) then you’re already in excellent shape. No AI can do that stuff, and for that alone no AI can replace people
   
2. This rhetoric is coming directly from the billionaires who are laying off tech people by the 100s of thousands as part of the class war they’ve been conducting against all working people since the 1940s. They want you to believe that you have to scramble and claw over one another to learn the “AI” that they’re forcing onto the world, so that you stop honing the skills that matter (see #1) and are easier to obsolete later. Don’t fall for it. It’s far from clear how this will shake out once governments get off their asses and start regulating this stuff, by the way–most of these “AI” tools are blatantly breaking copyright and other IP laws, and some day that’ll catch up with them.
   

That said, it is helpful to know thy enemy.

I’m not super a fan of using json. I feel we could still use text as the medium. Maybe a modified version to fix any weakness.

What if instead of signing each twt individually we generated a merkle tree using the twt hashes? Then a signature of the root hash. This would ensure the full stream of twts are intact with a minimal overhead. With the added bonus of helping clients identify missing twts when syncing/gossiping.

Have two endpoints. One as the webfinger to link profile details and avatar like you posted. And the signature for the merkleroot twt. And the other a pageable stream of twts. Or individual twts/merkle branch to incrementally access twt feeds.

I needed something to help with a morning schedule for two kiddos. It highlights the current 5-minute block as it goes. I think this was my first time reaching for JavaScript for a personal project. https://sidequest.club/stages.html

@eldersnake@we.loveprivacy.club Several reasons:

• It’s another language to learn (SQL)
  
• It adds another dependency to your system
  
• It’s another failure mode (database blows up, scheme changes, indexs, etc)
  
• It increases security problems (now you have to worry about being SQL-safe)
  

And most of all, in my experience, it doesn’t actually solve any problems that a good key/value store can solve with good indexes and good data structures. I’m just no longer a fan, I used to use MySQL, SQLite, etc back in the day, these days, nope I wouldn’t even go anywhere near a database (for my own projects) if I can help it – It’s just another thing that can fail, another operational overhead.

@abucci@anthony.buc.ci So.. The issue is that its showing the password by default? Would making an alias to always include the -c help? We can probably engage Jason with a PR to enable a more hardened approach when desired. I’ve spoken to him before and is generally a pretty open to ideas.

This is an upsert. So I pass a streamID which is like a globally unique id for the object. And then see how the type of the parameter in the function is used to infer the generic type. In the function it will create a new *Info and populate it from the datastore to pass to the function. The func will do its modifications and if it returns a nil error it will commit the changes.

The PA type contract ensures that the type fulfills the Aggregate interface and is a pointer to type at compile time.

Twitter has a new “social platforms” policy… is it maddening? Hilarious? Ridiculous? All of the above? I laughed, but to be clear, I don’t think ‘funny’ is a good way to describe it.

@prologic@twtxt.net, search for “quark” and you will get quack, quart, quirk, and all possible iterations. Not too helpful.

@prologic@twtxt.net Error handling especially in Go is very tricky I think. Even though the idea is simple, it’s fairly hard to actually implement and use in a meaningful way in my opinion. All this error wrapping or the lack of it and checking whether some specific error occurred is a mess. errors.As(…) just doesn’t feel natural. errors.Is(…) only just. I mainly avoided it. Yesterday evening I actually researched a bit about that and found this article on errors with Go 1.13. It shed a little bit of light, but I still have a long way to go, I reckon.

We tried several things but haven’t found the holy grail. Currently, we have a mix of different styles, but nothing feels really right. And having plenty of different approaches also doesn’t help, that’s right. I agree, error messages often end up getting wrapped way too much with useless information. We haven’t found a solution yet. We just noticed that it kind of depends on the exact circumstances, sometimes the caller should add more information, sometimes it’s better if the callee already includes what it was supposed to do.

To experiment and get a feel for yesterday’s research results I tried myself on the combined log parser and how to signal three different errors. I’m not happy with it. Any feedback is highly appreciated. The idea is to let the caller check (not implemented yet) whether a specific error occurred. That means I have to define some dedicated errors upfront (ErrInvalidFormat, ErrInvalidStatusCode, ErrInvalidSentBytes) that can be used in the err == ErrInvalidFormat or probably more correct errors.Is(err, ErrInvalidFormat) check at the caller.

All three errors define separate error categories and are created using errors.New(…). But for the invalid status code and invalid sent bytes cases I want to include more detail, the actual invalid number that is. Since these errors are already predefined, I cannot add this dynamic information to them. So I would need to wrap them à la fmt.Errorf("invalid sent bytes '%s': %w", sentBytes, ErrInvalidSentBytes"). Yet, the ErrInvalidSentBytes is wrapped and can be asserted later on using errors.Is(err, ErrInvalidSentBytes), but the big problem is that the message is repeated. I don’t want that!

Having a Python and Java background, exception hierarchies are a well understood concept I’m trying to use here. While typing this long message it occurs to me that this is probably the issue here. Anyways, I thought, I just create a ParseError type, that can hold a custom message and some causing error (one of the three ErrInvalid* above). The custom message is then returned at Error() and the wrapped cause will be matched in Is(…). I then just return a ParseError{fmt.Sprintf("invalid sent bytes '%s'", sentBytes), ErrInvalidSentBytes}, but that looks super weird.

I probably need to scrap the “parent error” ParseError and make all three “suberrors” three dedicated error types implementing Error() string methods where I create a useful error messages. Then the caller probably could just errors.Is(err, InvalidSentBytesError{}). But creating an instance of the InvalidSentBytesError type only to check for such an error category just does feel wrong to me. However, it might be the way to do this. I don’t know. To be tried. Opinions, anyone? Implementing a whole new type is some effort, that I want to avoid.

Alternatively just one ParseError containing an error kind enumeration for InvalidFormat and friends could be used. Also seen that pattern before. But that would then require the much more verbose var parseError ParseError; if errors.As(err, &parseError) && parseError.Kind == InvalidSentBytes { … } or something like that. Far from elegant in my eyes.

Alright, check this out. I just kinda completed today’s project of converting a jeans into a saw bag. It’s not fully done, the side seams on the flap need some more hand sewing, that’s for sure. No, I don’t have a sewing machine. Yet?

Image

At first I wanted to put in the saw on the short side, but that would have made for more sewing work and increased material consumption. As a Swabian my genes force me to be very thrifty. Slipping in on the long side had the benefit of using the bottom trouser leg without any modification at all. The leg tapers slightly and gets wider and wider the more up you go. At the bottom it’s not as extreme as at the top.

The bag is made of two layers of cloth for extra durability. The double layers help to hide the inner two metal snap fastener counter parts, so the saw blade doesn’t get scratched. Not a big concern, but why not doing it, literally no added efforts were needed. Also I reckon it cuts off the metal on metal clinking sounds.

The only downside I noticed right after I pressed in the receiving ends of the snap fasteners is that the flap overhangs the bag by quite a lot. I fear that’s not really user-friendly. Oh well. Maybe I will fold it shorter and sew it on. Let’s see. The main purpose is to keep the folding saw closed, it only locks in two open positions.

Two buttons would have done the trick, with three I went a bit overkill. In fact the one in the middle is nearly sufficient. Not quite, but very close. But overkill is a bit my motto. The sides making up the bag are sewed together with like five stitch rows. As said in the introduction, the flap on the hand needs some more love.

Oh, and if I had made it in a vertical orientation I would have had the bonus of adding a belt loop and carrying it right along me. In the horizontal layout that’s not possible at all. The jeans cloth is too flimsy, the saw will immediately fall out if I open the middle button. It’s not ridgid enough. Anyways, I call it a success in my books so far. Definitely had some fun.
