<FatalNIX> heat: I love how Ubuntu has been behind on everything. Elixir is almost completely broken as a package..
<FatalNIX> I don't particularly use Ubuntu outside of the machine they provide me at work, but Some of those packages are almost dinosaurs now.
Likorn has quit [Quit: WeeChat 3.4.1]
<heat> well 20.04 is 2 years old
<heat> the meson they package was almost brand new at the time
<FatalNIX> I ended up just upgrading the work machine I have to 21.04 or something..
<FatalNIX> because I need C20
<FatalNIX> Something I need to compile is using a bunch of crap that just won't compile with std=C2a
<heat> why do you need C20?
<FatalNIX> Apparently btop wouldn't compile without it
<FatalNIX> so I was like ok mess with the Makefile, tried c2a, and it complained that certain C20 features being used weren't there, so I was like ugh okay, gcc isn't compiled with C20 support...
<FatalNIX> I could have recompiled GCC but decided to upgrade Ubuntu instead and now it works XD
<heat> tbf it's C23
<heat> it's not even finished yet
<FatalNIX> OH, that's why.
<FatalNIX> Makes more sense now
<heat> using features from an unfinished standard is not the greatest idea
<FatalNIX> I'd agree
<FatalNIX> But I really wanted to see what the hype about btop was.
<FatalNIX> I generally use htop
<heat> oh you mean c++
<heat> that's definitely c++
<heat> btop is written in c++
freakazoid12345 has joined #osdev
<FatalNIX> YES
<heat> a compiler from 20.04 that doesn't have c++20 is very weird tbf
<FatalNIX> Sorry.
<FatalNIX> I forgot it was C++ :P

<FatalNIX> I spent like 2 minutes on it and was like wtf I'm upgrading anyways
fwg has joined #osdev
<heat> my ubuntu server 20.04 has c++2a
<FatalNIX> c++2a wouldn't compile it unfortunately
<heat> gcc 9.4 which is decently good
<heat> if they require such a new compiler, they should stop requiring such a new compiler
<FatalNIX> Slackware has GCC 11.2 atm
<FatalNIX> Kinda funny considering Ubuntu is supposed to be the bleeding edge? :P
<heat> huh?
<zid> irt backlog, I use rundll32 a lot still
<heat> ubuntu is everything but bleeding edge

<heat> FatalNIX, ya see, it's their fault
<heat> they're using ranges
<heat> ranges support hasn't even been finished yet
<heat> current gcc's ranges support is *incomplete*
<heat> requiring such a new toolchain without controlling the toolchain you're supposed to use is pretty damn
<heat> dumb*
<zid> The trick is to use so many new features people can't even try to hack around needing a new compiler
<zid> No more bug report for "Could you please change this one line so it works in C89?"
<FatalNIX> NO.
<zid> "What instrument do you play?" "Slot A"
<zid> Slot 1 I guess technically

<gog> i've been working on a unit test for a kde framework library and i can't make the windows CI pass. i'm beginning to think the plugin it depends on is broken
<gog> i'm actually looking into building qt for windows with mingw and running it against wine just to unbreak it
<gog> :|

<geist> Hmm that sounds unfun. What version of MSVC is current?
<geist> Did they release 2022?
<gog> i have no idea
<gog> i don't really have a windows machine to dev with
<gog> or i could reopen my merge request. i got frustrated because somebody asked me "why did you change the CMakeLists.txt? use kcoreaddons_add_plugin() instead" then somebody else coming in and saying "this is a tier1 framework, it can't depend on kca"

<heat> gog, i'm curious, any specific motivation for doing kde work recently?
<gog> heat: kidletime was broken and crashing lxqt-powermanagement
<gog> i fixed that bug and one of the maintainers asked me for a unit test
<gog> so i started doing that
<gog> but i had issues with it
<gog> i've mostly fixed the issues and the CI accepts it for Qt5 and 6 but the Windows plugin doesn't emit any signals
<j`ey> I would just disable the test for windows :P
<gog> leads are enabling windows CI globally for all tier1 frameworks
<gog> the pollign plugin for windows is just plain broken i think
<gog> or it doesn't work in the test environment for whatever reason
<gog> i have no means to investigate why
<heat> ah
<heat> I was thinking it could've been related to season of kde having started a few weeks back
<j`ey> I think thats reasonable to just disable it on windows then
<gog> nah, this was personal :p
<gog> it annoyed me so i fixed it
Likorn has joined #osdev
<gog> a good enough reason imo
<heat> just an fyi, google summer of code started accepting applications and there are plenty of os-like projects out there if anyone is interested

<heat> join T I A N O C O R E, the industry standard open source UEFI implementation
<heat> liberally licensed too
<heat> or coreboot if you're a weirdo
<gog> tianocore might be a good fit for me
<heat> damn right
<gog> hah, they want unit tests
<gog> might put together a proposal for that
<gog> the dynamic linking one is also intruiging because it aligns with what i've been working on in my own code
<gog> and possibly ACPI-CA test application
<gog> i know less about that though
<heat> if you need the money/experience I'd say that doing a large project is better

<gorgonical> When you sit down to start work on some program, do you have a routine you engage in? A snack or drink you prepare, a comfortable robe, etc? I know so people that have strange habits. I always make a big glass of iced tea
<dh`> a programmer is a device for turning tea into executable code
<gorgonical> The usual aphorism has to be changed when you come from the American south
<klange> If you use "caffeine" it is correct for tea, coffee, and soda.
<kingoffrance> also soap apparently
<moon-child> gorgonical: programmer socks!
<gorgonical> moon-child: Mine have bob ross's face on them
<gorgonical> klange: Makes me wonder about caffeine habits around the world. I imagine Europeans engage in different coffee habits. I have a dutch friend that has a nespresso machine I've never seen before. Makes cappucinos from pods
<gorgonical> Maybe I'm just behind the coffee machine tech
<heat> yeah I have that here
<heat> I tend to avoid caffeine as much as possible
<heat> a year or so ago I drank so much caffeine (coffee + red bull + monster energy) that my heart kinda started skipping beats and I'm afraid that I don't want to die
<heat> way healthier this way :)
<gorgonical> heat: I am either mostly resistant to caffeine or deeply dependent on it. I can usually consume 8-12 cups of tea a day with no noticeable caffeine side-effects
<gorgonical> Though tea is much less caffeinated
<shikhin> Heart skipping beats sounds like something that needs medical attention.
<j`ey> or youre in love
<heat> several weeks of unhealthy habits does that to ya
<heat> I stopped having any of that since I stopped

<dh`> if you're from the south, isn't "tea" shorthand for "sugar"? :-)
Burgundy has quit [Ping timeout: 268 seconds]
<gorgonical> dh`: It used to be. But then as a teenager I learned how it was made and now I only drink unsweetened tea
<gorgonical> If you like sweet tea, never ever watch it made
<dh`> when I was much younger I used to drink the bottled lipton stuff with lemon that was in vogue then
<dh`> it's terrible tea but it was ok as non-fizzy soda
<gorgonical> I did drink some of that stuff in college. It's not easy to get unsweet tea in the south
<dh`> but I am far too much of a tea snob to put sugar in my tea
<heat> why do you folks like tea so much?
<heat> is it a cultural thing?
<gorgonical> That's part of it. Really high-quality tea is very lovely, like good wine
<gorgonical> Obviously different, but the variability of good tea is like that
<gorgonical> Now to explain why we drink lipton or whatever, yes that's mostly cultural habit I would say
<kingoffrance> there's probably some history of not wanting to import tea due to a tax or something
<kingoffrance> some minor historical event
<dh`> pish
<kingoffrance> thats what ben franklin says, it was not about the tax
<dh`> it was about whether the tax was legal
<dh`> anyway when I was a kid I always liked the tea you got in chinese restaurants, and eventually discovered that you can secure good tea other ways
<dh`> (and it's a lot easier now, you can get adequate tea in supermarkets now, at least in cosmopolitan areas, and that was absolutely not true in the 80s)
<dh`> (and there are lots of places to order good tea from)
<gorgonical> A lot like coffee, too. The only thing I continually want for is good oolong tea. It doesn't even have to be loose-leaf
<gorgonical> :(

<klange> you could apply the same techniques to drive a single LED, yielding a 1×1 display and handily beating this for the title

<Griwes> but what if you pretended to be an rgb 1x1 display, but only used one of the colors in the signal to drive the led?
<klange> That might win on "worst", but I fear it's falling into the realm of not actually qualifying as functional.
<gog> its functional if you only have a parietal eye
<Griwes> Noone said anything about "qualifying as functional" ;D
