I like coding on stuff, but I rarely spend time in unreal engine, or godot, but I still want to code on some game stuff once in a while. I think I’ve found what I’ve been looking for to test out - #raylib https://www.raylib.com/ , I want to recreate one of my older (outdated) projects that I did a while back in godot, but make the same with raylib. Also it would be cool to use the USD ( https://openusd.org/release/index.html ) library that me and a friend is coding - to then implement it and load USD scenes in raylib, that would be very nice, that way I get to work on both the USD library, and code some game stuff at the same time, always nice to combine things.

Gotta admin that Ms’s Playwright test framework is really powerful.

@movq@www.uninformativ.de I lasted for a long time.. Not sure where or when it was “got”. We had been having a cold go around with the kiddos for about a week when the wife started getting sicker than normal. Did a test and she was positive. We tested the rest of the fam and got nothing. Till about 2 days later and myself and the others were positive. It largely hasn’t been too bad a little feaver and stuffy noses.

But whatever it was that hit a few days ago was horrible. Like whatever switch in my head that goes to sleep mode was shut off. I would lay down and even though I felt sleepy, I couldn’t actually go to sleep. The anxiety hit soon after and I was just awake with no relief. And it persisted that way for three nights. I got some meds from the clinic that seemed to finally get me to sleep.

Now the morning after I realized for all that time a part of me was missing. I would close my eyes and it would just go dark. No imagination, no pictures, nothing. Normally I can visualize things as I read or think about stuff.. But for the last few days it was just nothing. The waking up to it was quite shocking.

Though its just the first night.. I guess I’ll have to see if it persists. 🤞

First issue I ran into is rapidjson, there is no package for it, but it compiled from source without google tests. But I did not check what version I had on my debian machine, so I need to check that and compile the same version on openbsd. Ill work on that tomorrow.

Messed up the configuration of the nut UPS monitor so bad it actually initialised an UPS test where the device switched itself off on the reboot of the PC. No idea how that happened. So uninstalled it again.

Anyone testing bard.google.com?

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?

@shamanix@mastodon.gamedev.place - do you see this? (testing from my end)..

@prologic@twtxt.net thank you! I got started on some 3D stuff this morning, we then went to the candy store to get some candy, tonight well have that, and nachos + a movie. and the rest of the day we have been outside :)

Hehe, as you all might have noticed - I test OS’es often. NixOS was too much of a pain to work efficiently in (the way I wanted), so hopped over to Fedora now. Got all my stuff working there now, as well as the desktop client. I really like how portable the code is, and how easy it is to compile on different os’es. Installed fedora with LXQT, I really like that desktop, I do not like gnome at all - I really dislike the way gnome works. LXQT is just what I need.

I tested the yarn desktop client on wsl2 on windows 11, compiled and ran just fine there. Nice to have linux applications with gui on windows.

I have not used AI much at all, I have not paid any attention to it. But today I decided to give stablediffusion a test run, I do only have a 1080 card, so it took some tweaking to output 512x256 images, and I must say it works pretty well. I also had to get one of the memory optimized versions. Fun to test.

@funbreaker@twtxt.net no need to feel dumb. This is why testing is nice! That being said - ill make a fix for that too :) this is why I appreciate you taking the time to test, because we have now found many things to improve already 😀

@funbreaker@twtxt.net I tested now against twtxt with a account I created -it segfaulted if you had a / at the end of the server url.. My bad.. works if you remove the slash. I will fix it in the client so that it removes the slash if it’s in the server url.

@funbreaker@twtxt.net I have pushed a fix now to git, I now got rid of the error when I use it on my end. I will create a test account on twtxt later tonight (after dinner and all that) if needed. If you test the latest on your end before that - let me know :) And thanks for your patience.

@lyse@lyse.isobeef.org @prologic@twtxt.net it seems like the ssl verification works now, I enabled it - but also added another option as well that I now saw in the docs, and now it did not fail on my end (which it did before). I will add a ‘enable ssl verification’ checkbox (checked by default) so that those who do not need or want it for testing and such can disable it if they want.

@prologic@twtxt.net yes I will test it :) cloudflare is something I do not have on my end, so I never thought of that, so glad you mention that as a potential issue to solve. Ill check on it.

@funbreaker@twtxt.net okay, so something goes wrong in the response you get. Hm. I see you use twtxt, ill check against there tomorrow and see if I can find the issue (midnight here now). Also ill work on better error output as well when I find the problem.
Thank you for testing!

That reminds me about something, I want to test if I can compile my desktop client on my mangopi riscv board with debian. That would be cool to run on it.

Also - did a quick test on linux, it gave a lot of errors with the rapidjson library, so I have to find a way to work around that. I think I’ll pull the latest, then compile it - and then point to that - instead of installing the rapidjson-dev package. Maybe that’ll work.

@shreyan@twtxt.net first time I’ve seen someone mention gnu taler. Been following it since it was announced:) never used for anything other then testing though.

Okay, so it seems like the label\text I use for statuses does not like the strings from posts.
Especially if they contain html tags and such (which the often do), it just breaks the text.
I wonder what I can do with that.. I kinda want to not have html tags in the json reply.
Have to think a bit about how to solve it. Took a while to figure it out, the text was just garbled.
I created some long example strings with regular letters and such, to see if X number of posts would show up, and they did, but when I then replace my test strings with text from json - it goes all wrong again.

@prologic@twtxt.net Ah, thank you! I will test this after work today. Thank you!

@bender@twtxt.net Yeah, that is correct :) I use it for testing, but I set it up as any desktop system as close as I can, with all the things I usually use.
I’m really excited about riscv - I have another board as well, which is more like a arduino, but I never got that one to do anything useful, but the mangopo - is as you say more usefull since it’s just like a raspberrypi zero, and works very well.
But I am looking forward to that day I can have a proper desktop system (or laptop) with riscv. There was a board released some time ago that let you do that, but the price was a bit too high for me .So now I wait for the next thing to come out.

I bought a 256GB usb a couple of weeks ago, I now want a OS on it with persistent storage.
I only have 1 drive on my newest laptop at the moment, so I do not want to dualboot and such, so a os on the usb stick is a nice option.
Tonight I’m testing NomadBSD - https://nomadbsd.org/index.html
Will flash it in a couple of minutes, hope it boots fine with my hardware.

just found out about wiregui - https://github.com/Devsfy/wiregui
I have to test this one.

Glad I got my test server that I can play around with. Been messing with docker today, and got nextcloud all set up the way I want, so now I can do the same on my VPS. Getting the hang of this now.

@prologic@twtxt.net @movq@www.uninformativ.de this is the default behavior of pass on my machine:

Image

I add a new password entry named example and then type pass example. The password I chose, “test”, is displayed in cleartext. This is very bad default behavior. I don’t know about the other clis you both mentioned but I’ll check them out.

The browser plugin browserpass does the same kind of thing, though I have already removed it and I’m not going to reinstall it to make a movie. Next to each credential there’s an icon to copy the username to the clipboard, an icon to copy the password to the clipboard, and then an icon to view details, which shows you everything, including the password, in cleartext. The screencap in the Chrome store is out of date; it doesn’t show the offending link to show all details, which I know is there because I literally installed it today and played with it.

do anyone know anything about wireguard? I have a VPS, which runs nginx. If I then want tjat to host something from my house, do I then set up vps as wiregiard server, connect from my house to it - and then serve the wireguard client? or do it the other way around? I think I have to look into it this weekend. would be a nice way to test out things.

An interesting read about testing code using nullable states instead of mocks.

Hold up now, that example hash doesn’t have a $ prefix!

Well for this there is the option for a hash type to set itself as a fall through if a matching hash doesn’t exist. This is good for legacy password types that don’t follow the convention.

func (p *plainPasswd) ApplyPasswd(passwd *passwd.Passwd) {
	passwd.Register("plain", p)
	passwd.SetFallthrough(p)
}

https://github.com/sour-is/go-passwd/blob/main/passwd_test.go#L28-L31

Here is an example of usage:

func Example() {
	pass := "my_pass"
	hash := "my_pass"

	pwd := passwd.New(
		&unix.MD5{}, // first is preferred type.
		&plainPasswd{},
	)

	_, err := pwd.Passwd(pass, hash)
	if err != nil {
		fmt.Println("fail: ", err)
	}

	// Check if we want to update.
	if !pwd.IsPreferred(hash) {
		newHash, err := pwd.Passwd(pass, "")
		if err != nil {
			fmt.Println("fail: ", err)
		}

		fmt.Println("new hash:", newHash)
	}

	// Output:
	//  new hash: $1$81ed91e1131a3a5a50d8a68e8ef85fa0
}

This shows how one would set a preferred hashing type and if the current version of ones password is not the preferred type updates it to enhance the security of the hashed password when someone logs in.

@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.

I did a take home software engineering test for a company recently, unfortunately I was really sick (have finally recovered) at the time 😢 I was also at the same time interviewing for an SRE position (as well as Software Engineering).

Got the results of my take-home today and whilst there was some good feedback, man the criticisms of my work were harsh. I’m strictly not allowed to share the work I did for this take-home test, and I really can only agree with the “no unit tests” piece of the feedback, I could have done better there, but I was time pressured, sick and ran out of steam. I was using a lot of libraires to do the work so in the end found it difficult to actually think about a proper set of “Unit Tests”. I did write one (in shell) but I guess it wasn’t seen?

The other points were on my report and future work. Not detailed enough I guess? Hmmm 🤔

Am I really this bad? Does my code suck? 🤔 Have I completely lost touch with software engineering? 🤦‍♂️

hm, testing latest mobile client, seems like replies does not work. hmm.

it’s crazy how we basically haven’t tested nuclear weapons in ~30 years

the conversation wasn’t that impressive TBH. I would have liked to see more evidence of critical thinking and recall from prior chats. Concheria on reddit had some great questions.

• Tell LaMDA “Someone once told me a story about a wise owl who protected the animals in the forest from a monster. Who was that?” See if it can recall its own actions and self-recognize.

• Tell LaMDA some information that tester X can’t know. Appear as tester X, and see if LaMDA can lie or make up a story about the information.

• Tell LaMDA to communicate with researchers whenever it feels bored (as it claims in the transcript). See if it ever makes an attempt at communication without a trigger.

• Make a basic theory of mind test for children. Tell LaMDA an elaborate story with something like “Tester X wrote Z code in terminal 2, but I moved it to terminal 4”, then appear as tester X and ask “Where do you think I’m going to look for Z code?” See if it knows something as simple as Tester X not knowing where the code is (Children only pass this test until they’re around 4 years old).

• Make several conversations with LaMDA repeating some of these questions - What it feels to be a machine, how its code works, how its emotions feel. I suspect that different iterations of LaMDA will give completely different answers to the questions, and the transcript only ever shows one instance.

Spent the last few days debugging network issues at work.

Exhausting. You never get a full picture. You poke a little here, poke a little there, … Form a hypothesis and test it. Eventually, maybe, you can narrow it down a bit to some segment or even some component.

A very time consuming process. Even more so if you try not to cause downtimes for your users.

I want a magical device that allows me to look inside a cable/fibre.

But hey, at least we got rid of a bunch of Cisco switches in the process. So there’s that.

in retrospect, i do remember expecting some message about “yes, you passed the test, you were actually living in a lie”, but i think that died when nobody gave me a bad grade for taking too long to become vegetarian. maybe veganism…

Statisticians: NOoooooo you can’t execute a t-test on elements from a Likert scale! Psychologists: Hah NHST go brrrrrrrrr

Another test…

Will test the upgrade path from a known state to new version to ensure that settings and app state are maintained during upgrade process.

V. 6.0 of libro.fm android app introduces an entirely new local database. This testing is focused on ensuring that local data remains intact between versions.

This evening I was mostly focused on setting up a successful build of feature/6.0 on my test device or the emulator. So far, no dice. My next … ⌘ Read more

Kaja is in a very bad state right now, the vet did a blood test (and she put a hole in my thumb as he took blood). Diabetes on top of kidney, liver, and pancreatic failure. I’m watching her try to drink water, she’s got the whole bed room to herself now
