Now WTF!? Suddenly, @falsifian@www.falsifian.org’s feed renders broken in my tt Python implementation. Exactly what I had with my Go rewrite. I haven’t touched the Python stuff in ages, though. Also, tt and tt2 do not share any data at all.

By any chance, did you remove the ; charset=utf-8 from your Content-Type: text/plain header, falsifian?

@mckinley@twtxt.net To answer some of your questions:

Are SSH signatures standardized and are there robust software libraries that can handle them? We’ll need a library in at least Python and Go to provide verified feed support with the currently used clients.

We already have this. Ed25519 libraries exist for all major languages. Aside from using ssh-keygen -Y sign and ssh-keygen -Y verify, you can also use the salty CLI itself (https://git.mills.io/prologic/salty), and I’m sure there are other command-line tools that could be used too.

If we all implemented this, every twt hash would suddenly change and every conversation thread we’ve ever had would at least lose its opening post.

Yes. This would happen, so we’d have to make a decision around this, either a) a cut-off point or b) some way to progressively transition.

Go 機器學習框架之火重燃，Google 前研究員開源期望媲美 Jax 的 GoMLX
Go 作爲一門兼具高性能與簡潔性的編程語言，近年來在各種領域得到廣泛應用。然而，在機器學習領域，Go 相比 Python、C++、Julia 等語言，生態仍然較爲薄弱。目前的 Go 機器學習框架無論在功能全面性上，還是在社區生態支持上都難以與 TensorFlow、PyTorch、Jax 等重量級框架抗衡。究其原因，筆者覺得還是 Go 社區缺少熟悉和精通機器學習方面的人才。不過，隨着時間的推移，總 ⌘ Read more

I love shell scripts because they’re so pragmatic and often allow me to get jobs done really quickly.

But sadly they’re full of pitfalls. Pitfalls everywhere you look.

Today, a coworker – who’s highly skilled, not a newbie by any means – ran into this:

$ bash -c 'set -u; foo=bar; if [[ "$foo" -eq "bar" ]]; then echo it matches; fi'
bash: line 1: bar: unbound variable

Why’s that happening? I know the answer. Do you? 😂

Stuff like that made me stop using shell scripts at work, unless they’re just 4 or 5 lines of absolutely trivial code. It’s now Python instead, even though the code is often much longer and clunkier, but at least people will understand it more easily and not trip over it when they make a tiny change.

The EU’s Proposed CRA Law May Have Unintended Consequences for the Python Ecosystem (as well as the entire free software movement).

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. :-)

@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.
