@movq@www.uninformativ.de Yeah, most of the graphical applications are actually KDE programs:

• KMail – e-mail client
  
• Okular – PDF viewer
  
• Gwenview – image viewer
  
• Dolphin – file browser
  
• KWallet – password manager (I want to check out pass one day. The most annoying thing is that when I copy a password, it says that the password has been modified and asks me whether I want to save the changes. I never do, because the password is still the same. I don’t get it.)
  
• KPatience – card game
  
• Kdenlive – video editor
  
• Kleopatra – certificate manager
  

Qt:

• VLC – video player
  
• Psi – Jabber client (I happily used Kopete in the past, but that is not supported anymore or so. I don’t remember.)
  
• sqlitebrowser – SQLite browser
  

Gtk:

• Firefox – web browser
  
• Quod Libet – music player (I should look for a better alternative. Can’t remember why I had to move away from Amarok, was it dead? There was a fork Clementine or so, but I had to drop that for some unknown reason, too.)
  
• Audacity – audio editor
  
• GIMP – image editor
  

These are the things that are open right now or that I could think of. Most other stuff I actually do in the terminal.

In the past™, I used the Python KDE4 bindings. That was really nice. I could pass most stuff directly in the constructor and didn’t have to call gazillions of setters improving the experience significantly. If I ever wanted to do GUI programming again, I’d definitely go that route. There are also great Qt bindings for Python if one wanted to avoid the KDE stuff on top. The vast majority I do for myself, though, is either CLI or maybe TUI. A few web shit things, but no GUIs anymore. :-)

I have finished 1-9 on Python. If anyone is interested, I could share the code, or in Reddit many people have shared theirs.

@andros@twtxt.andros.dev If something fits in a CSV file, it typically doesn’t require a database. I agree with that. Depending on the application, more complicated queries might benefit from a database, though. I don’t know awk very well, but I could imagine that grep, sed and cut reach their CSV processing limits rather quickly when you have to deal with escaped (multiline) fields.

I only very rarely have to deal with CSV files or databases in my day to day life. Maybe, these classic Unix tools offer some tricks I’m not aware of. When I have some more complicated CSV input, I generally reach for Python.

Ontem voltei a pegar no Django depois de 10 anos para um side-project. É como se fosse um regresso a um lugar onde um dia se foi feliz.

Tem a sua personalidade e tal, mas continuo a adorar os seus pormenores e as suas escolhas sobre como deve funcionar uma framework web.

Também fiquei muito agradado de ver que muito pouco mudou desde há uma década no que toca à forma fundamental como o Django faz as coisas. Talvez isso não seja apreciado pela juventude habituada a ciclos de upgrade rápidos e drásticos, mas pra mim foi um grande alívio ver que não tenho de me atualizar muito para montar um pequeno projeto.

description = 🏗 Full-Stack developer (Mainly Python) ✍ Writer[...]

I’m developing a tutorial for the Django Girls. Does anyone here have experience with #Django ? #python

The project is a POC (Proof of Concept) that went into production and the company has customers who are using it. The developers had been working for several years, without testing, structure, isolation and so on. The company hired me to transform the project into a real product. There are in my hands 422 python files to transform that they beg me a refactore, architecture and testing. Every developer’s bad dream.
My first step is to read and understand the tree because there are apps inside other apps call each other. I am very determined to work on a new repository.

@prologic@twtxt.net Which one? I don’t mind the ternary operator at all. In fact, I often find myself missing it in Go. I don’t find the two alternatives particularly elegant:

foo := "eggs"
if bar {
    foo = "spam"
}

Or:

var foo string
if bar {
    foo = "spam"
} else {
    foo = "eggs"
}

To my eye, this just would look a lot nicer:

foo := bar ? "spam" : "eggs"

Or at least as the Pythons do it:

foo = "spam" if bar else "eggs"

The ternary operator especially shines with relatively short expressions.

For many years I have found Flask to be too basic a tool for modern development. But since I create APIs using Flask with Pydantic to validate the input data, some middlewares for parsing and Blueprint to separate the code into modules… I must admit that I am super comfortable, fast and easy to test.

What is clean architecture? That’s a good question.

You think of a pattern for ordering code with good decisions isolating technologies (you can change the web framework or database without break the business logic), easy to test (you only test interfaces and use cases), sharing code between frameworks (entities and use cases), scalability, modulations and standardizing names. Clean architecture is not perfect, it has a learning curve and some abstraction in each technology. You can even find rejection with yours colleagues.
I have a good article on this topic.

@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.

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.

have to admit that switching to python & numpy for data analysis from klong relieves me from a huge pain in the ass—klong is just slow for that.

I’ve made some fixes to twtxt to make it work with Python 3.7+. I hope @buckket@buckket.org will apply this patch!

I feel like it took me a bit longer to fully understand how to work in Smalltalk than it did most languages. The IDE is different than anything I’ve used before, and probably anything you’ve seen as well. You’re not going to be opening myscript.st in your favorite text editor, and then run it from the command line as you would a Python program. It takes a little mental adjustment to start with.

That’s not the warning, howe … ⌘ Read more

@lyse@lyse.isobeef.org I’m a big fan of using PyCharm and IntelliJ on large Python and Java codebases respectively. In my personal life, I mostly use Emacs (because I don’t hack much Java outside of work), but I do wonder what GoLand is like.

JavaScript : web apps

wut?! 😳 seriously?! 🤦‍♂️

Python : small tools

Okay 👌

Go: micro services

Umm bad generalization 🤣 – Example yarnd that powers most of Yarn.social 😂

Java: enterprise software

Yes! Oh gawd yes! 🤣 And Java™ needs to die a swift death!

C: crimes

Hmmm? 🤔 I feel this one is going to have some backslash and/or go the way of “Hacker” being misconstrued to mean entirely different/incorrect things as is what’s happening in the media (for various definitions of “media”).

@movq@www.uninformativ.de I would not mind keeping a diff, if you tell me where to make the changes! I know nothing of Python, and I have spent already a couple of hours trying to make sense. I know it is there, in front of me, if only I knew Python. 😩
