@lyse@lyse.isobeef.org @movq@www.uninformativ.de Oh, I had a experience this weekend as well, a dog was barking in the forest, sounded like something was wrong (it’s a fairly public area), I then continued my walk, and Nanook got more and more nervous, I then continued the walk, and Nanook froze. I could still hear the dog barking quite close. And then someone shot a rifle. I’m glad I did not walk up to where that dog was, I kinda wanted too, because I first thought maybe something was wrong. But it honestly weirded me out that they did this in such a place as they did, almost called the cops to be honest to check with them, but I did not at the time..

I understand your thoughts on this, but I would not call it a failure - because you learned a lot from it, and lots of things worked as well.
And there are alternatives for those who needs\wants activitypub, so I think also yarn\twtxt benefits from you focusing on that instead of dealing with the frustrations of activitypub integration. And maybe it’ll feel a bit better to put that on the backburner? :)

Question to all you Gophers out there: How do you deal with custom errors that include more information and different kinds of matching them?

I started with a simple var ErrPermissionNotAllowed = errors.New("permission not allowed"). In my function I then wrap that using fmt.Errorf("%w: %v", ErrPermissionNotAllowed, failedPermissions). I can match this error using errors.Is(err, ErrPermissionNotAllowed). So far so good.

Now for display purposes I’d also like to access the individual permissions that could not be assigned. Parsing the error message is obviously not an option. So I thought, I create a custom error type, e.g. type PermissionNotAllowedError []Permission and give it some func (e PermissionNotAllowedError) Error() string { return fmt.Sprintf("permission not allowed: %v", e) }. My function would then return this error instead: PermissionNotAllowedError{failedPermissions}

At some layers I don’t care about the exact permissions that failed, but at others I do, at least when accessing them. A custom func (e PermissionNotAllowedError) Is(target err) bool could match both the general ErrPermissionNotAllowed as well as the PermissionNotAllowedError. Same with As(…). For testing purposes the PermissionNotAllowedError would then also try to match the included permissions, so assertions in tests would work nicely. But having two different errors for different matching seems not very elegant at all.

Did you ever encounter this scenario before? How did you address this? Is my thinking flawed?

💭 While some people like to jump between blogging software all the time, or go back to Hugo from a custom one, I don’t really miss Hugo after switching to GoBlog in 2020, but enjoy having my own system quite a bit. Not that Hugo, WordPress, etc. are bad blogging systems, but I really enjoy being able to quickly code a fix without having to research docs, StackOverflow, or the source on GitHub. And when I have an idea for a new feature, it would often not be easy to implement in the existing systems. ⌘ Read more

I played around with parsers. This time I experimented with parser combinators for twt message text tokenization. Basically, extract mentions, subjects, URLs, media and regular text. It’s kinda nice, although my solution is not completely elegant, I have to say. Especially my communication protocol between different steps for intermediate results is really ugly. Not sure about performance, I reckon a hand-written state machine parser would be quite a bit faster. I need to write a second parser and then benchmark them.

lexer.go and newparser.go resemble the parser combinators: https://git.isobeef.org/lyse/tt2/-/commit/4d481acad0213771fe5804917576388f51c340c0 It’s far from finished yet.

The first attempt in parser.go doesn’t work as my backtracking is not accounted for, I noticed only later, that I have to do that. With twt message texts there is no real error in parsing. Just regular text as a “fallback”. So it works a bit differently than parsing a real language. No error reporting required, except maybe for debugging. My goal was to port my Python code as closely as possible. But then the runes in the string gave me a bit of a headache, so I thought I just build myself a nice reader abstraction. When I noticed the missing backtracking, I then decided to give parser combinators a try instead of improving on my look ahead reader. It only later occurred to me, that I could have just used a rune slice instead of a string. With that, porting the Python code should have been straightforward.

Yeah, all this doesn’t probably make sense, unless you look at the code. And even then, you have to learn the ropes a bit. Sorry for the noise. :-)

Got some good progress on the GTK gui today, got the timeline to work!
Took some time to figure out how the UI layout stuff works, but it looks good now.
I will add the avatars next.

The way it is right now - I got this up and running in a couple of hours, instead of ‘days’ with FLTK.
So I’m glad I made the decision to switch to GTK,
Right now I’m doing all development on Trisquel OS, windows version will come later on.

Also - since I thought about the possibility that I wanted to switch early in the process the code that does all the work is UI independent, meaning this was easy to do. +1 for planning ahead.. :)
I will post a screenshot of the new UI soon, once it’s a bit polished.

@prologic@twtxt.net I like it, I get to follow some people I could not follow before, which I find useful.
But if you have second thoughts about it all - then I can understand that.
If you decide to pull the plug on it - then I’ll just get some additional activitypub service installed on my server and use that for that (I was thinking about installing this: https://github.com/tsileo/microblog.pub ) if needed.

Q: Is anyone actually finding the activitypub experimental feature I’ve been working on (for those running main) actually useful? 🤔 (because I’m not and having second thoughts…)

👋 Hey y’all yarners 🤗 – @darch@neotxt.dk and I have been discussing in our Weekly Yarn.social call (still ongoing… come join us! 🙏) about the experimental Yarn.social <-> Activity Pub integration/bridge I’ve been working on… And mostly whether it’s even a good idea at al, and if we should continue or not?

There are still some outstanding issues that would need to be improved if we continued this regardless

Some thoughts being discussed:

• Yarn.social pods are more of a “family”, where you invite people into your “home” or “community”
  
• Opening up to the “Fedivise” is potentially “uncontrolled”
  
• Even at a small scale (a tiny dev pod) we see activities from servers never interacted with before
  
• The possibility of abuse (because basically anything can POST things to your Pod now)
  
• Pull vs. Push model polarising models/views which whilst in theory can be made to work, should they?
  

Go! 👏

Trying to wrap my head around webfinger..

my first thoughts about it were that a subject of acct:me@sour.is would have a listing of rel’s for the different accounts that are related to me (ie. yarn, salty, twitter, mastodon, etc…)

but maybe my thinking is at the wrong level.. that each of those accounts would be on a subject level and the rels are describing different aspects of that account. so i would have salty:acct:xuu@sour.is, twitter:acct:xuu, mastodon:acct:xuu@chaos.social, yarn:acct:xuu@ev.sour.is and then i could have a main acct:me@sour.is that links them together as aliases.

I found okta will do something similar with its accounts to show as okta:acct:user@domain so maybe I am on to something?

@movq@uninformativ.de yeah.. i rewrote it a few times because i thought there was something breaking.. but was mistaken
though now i am seeing a weird cache corruption.. that seems to come and go.

Moving to another city
As I’ve probably written many times before (have I?), I’m currently moving with my girlfriend to her university town. I will keep my old apartment as a second home. But it’s still my first move to another city and I’m just realizing it. ⌘ Read more

I was inclined to let this go so as not to stir anything up, but after some additional thought I’ve decided to call it out. This twt:

is exactly the kind of ad hominem garbage I came to expect from Twitter™, and I’m disappointed to see it replicated here. Rummaging through someone’s background trying to find a “gotcha” argument to take credibility away from what a person is saying, instead of engaging the ideas directly, is what trolls and bad faith actors do. That’s what the twt above does (falsely, I might add–what’s being claimed is untrue).

If you take issue with something I’ve said, you can mute me, unfollow me, ignore me, use TamperMonkey to turn all my twts into gibberish, engage the ideas directly, etc etc etc. There are plenty of options to make what I said go away. Reading through my links, reading about my organization’s CEO’s background, and trying to use that against me somehow (after misinterpreting it no less)? Besides being unacceptable in a rational discussion, and besides being completely ineffective in stopping me from expressing whatever it is you didn’t like, it’s creepy. Don’t do that.

Because I used Prometheus and Grafana at work, I also tried them at home and I must say, monitoring isn’t as boring as I always thought. Next up Kubernetes? 😅 ⌘ Read more

I was just reminded of this interpreter for an APL/J-like language by Arthur Whitney, the absolute weirdest bit of C code I’ve actually gotten something out of, and thought I’d share: https://code.jsoftware.com/wiki/Essays/Incunabulum

After all, debugging is still fun!
One reason I use an Android smartphone is that there are apps like Indigenous (a MicroPub-compatible app for posting from your phone to a MicroPub-compatible blog). And even if the app ever disappears from the store, there’s still the option to manually install the app. And if you need to, you can also develop your own apps without having to invest nearly $100 a year. ⌘ Read more

Prosodical Thoughts: Mutation Testing in Prosody
This is a post about a new automated testing technique we have recently
adopted to help us during our daily development work on Prosody. It’s probably
most interesting to developers, but anyone technically-inclined should be able
to follow along!

If you’re unfamiliar with our project, it’s an open-source real-time messaging
server, built around the XMPP protocol. It’s used by many organizations and
self-hosting hobbyists, and also powers applications such as [Snikke … ⌘ Read more

First work day in my new job
My first day at my new job is over, and it went quite well despite the lack of sleep. Super nice colleagues and I am already full in the training. ⌘ Read more

Why can’t I sleep when I’m excited? And why am I not excited during the day, but then my thoughts are circling at night? Well at least I slept well yesterday. Maybe that helps to get through the day somehow after only 3 or 4 hours of sleep. ⌘ Read more

real world software development is a never-ending series of compromises Thoughts on why sometimes programming/software engineering discussions suck | Hacker News

@mckinley@twtxt.net Haha, while composing I was wondering two or three times whether I should throw my thoughts in an HTML page instead. But out of utter laziness I discarded that idea. ¯_(ツ)_/¯

@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.

Hi, I am playing with making an event sourcing database. Its super alpha but I thought I would share since others are talking about databases and such.

It’s super basic. Using tidwall/wal as the disk backing. The first use case I am playing with is an implementation of msgbus. I can post events to it and read them back in reverse order.

I plan to expand it to handle other event sourcing type things like aggregates and projections.
