er u may assume the text has spaces in it

ill change it so no punctation is allowed either

upper+lowercase allowed

@DialFrost Wouldn't it be "The quick brown fox jumps the dog"?

@mathcat drat, foiled again

ta Radvylf srik su shilani

Any feedback on Inject arbitrary code into a compiler?

@AaroneousMiller Just a warning, I don't know if Vyxal would qualify for this CnR

Due to the requirements about the language being deterministic

And it also specifies the cop should make the language, so you'd probably just have to make a version of "vyxal" with the subset of features required for the ACE

Aaroneous Miller

@taRadvylfsriksushilani Vyxal has some commands for RNG, but other than that it's completely deterministic, to the best of my knowledge

@taRadvylfsriksushilani I helped make Vyxal

ta Radvylf srik su shilani

Hmm, I guess that'd count.

Aaroneous Miller

If you don't think it qualifies that's fine, I'll leave it up to you

ta Radvylf srik su shilani

14:40

It's a bit of an exception under the current rules I guess, but excluding an ACE in vyxal wouldn't be very fun

Just like...answer in "Vyxal but don't use the RNG operators" and I'll be fine with it :p

Considering the width and height of the plus as a unit, and O is the bottom-left corner.

Fortunately, the charging one has been solved now that we've all standardized on mini-USB. Or is it micro-USB? Shit.

ta Radvylf srik su shilani

Windows: Most common, but kinda sucks in a lot of ways
MacOS: Pricy hardware and lacks some freedom
Linux: Not evil but very ugly and lacks compatibility with lots of stuff
Chrome OS: Only good for cheap laptops
iOS/Android: I'm not writing code on a screen that tiny

If only we had a small, secure, nice looking OS with extremely good hardware and application support

user

@taRadvylfsriksushilani phones boot quickly (well they never shut down

ta Radvylf srik su shilani

But we can't even manage to get good support for linux after decades

@user I only gave them gray since when you do shut them down or update them, it's kinda inconvenient

user

Because no corporation owns it and there’s a million distros

Ginger Industries

16:32

@taRadvylfsriksushilani so you want Linux but it can run Windows apps?

user

@taRadvylfsriksushilani isn’t chrome os the same once you shut down?

Ginger Industries

@user I'm sorry once you what

user

@GingerIndustries i think they want more appa for linux

@GingerIndustries shut

ta Radvylf srik su shilani

Linux needs something like a Microsoft, that runs it on hundreds and hundreds of computers and makes sure any compatibility issues are fixed, and keeps graphic designers on salary so they can make it look good

user

Ubuntu kinda like that

ta Radvylf srik su shilani

16:33

But they're too Microsoft

And Ubuntu still manages to be ugly and have bad compatibility

user

But people are just so used to mac and windows and linux doesn’t advertise

ta Radvylf srik su shilani

@user Chromebooks boot up almost instantly

user

@taRadvylfsriksushilani because they’re not enough like microsoft (not that being a big bad corp is good)

@taRadvylfsriksushilani mine takes half a minute :(

Ginger Industries

@taRadvylfsriksushilani ubuntu gets closest to what you want

ta Radvylf srik su shilani

@user And yet they already do the bad-Microsoft-things, like centering things around profit too much

We need an OS made by a non-profit company

Ginger Industries

16:35

@taRadvylfsriksushilani well do you have any suggestions?

user

What do you expect them to do? Profit is why they exist

ta Radvylf srik su shilani

That can take care of advertising and testing and UI/UX, but that doesn't have to be overly bad

user

@taRadvylfsriksushilani yes

Ginger Industries

y'know actually

we're kinda in an Alexander Graham Bell-type situation here

user

Remember that Non profits aren’t always good tho

we've got all the parts for a good-looking, well-built Linux-based distro but we just haven't put it together

user

@taRadvylfsriksushilani :(

ta Radvylf srik su shilani

Windows feels kind of...idk, bloated. An OS should be kinda small IMO. It's the base that your apps run on, not the whole entire computer.

user

@GingerIndustries good looking distros exist already

ta Radvylf srik su shilani

16:36

I kinda think we should start from scratch honestly

Windows and Linux both have decades of compatibility stuff they have to deal with, and have security and other issues that can never be resolved, ever

user

@taRadvylfsriksushilani what? No don’t take away my preinstalled microsoft todo and solitaire what would i do without them /s

@taRadvylfsriksushilani have you considered that this is hard

Ginger Industries

Lots of applications? flatpak/snapcraft + some sort of APT gui
Good design? plenty of desktops to choose from
Price? Free
Just works? this is the hard part but I think it can be done

ta Radvylf srik su shilani

@user Yes

user

Any software will get compat issues eventually anyway, best to stick to linux

@taRadvylfsriksushilani like really hard

Ginger Industries

@taRadvylfsriksushilani these are kinda unavoidable consequences of making an OS

ta Radvylf srik su shilani

16:38

I disagree

Ginger Industries

methinks it's about as good as it's gonna get

user

^

ta Radvylf srik su shilani

Unfortunately, for practical reasons, I do too

user

I’m hopeful about linux support getting better but it probably won’t change much

ta Radvylf srik su shilani

Linux has massive compat issues despite existing for decades, so anything new is virtually guaranteed to fail unless all of the major companies were backing it and there was enormous incentive for app developers to port things to it

user

16:40

Also the boot time isn’t a huge issue imo, but small linuxes exist already

ta Radvylf srik su shilani

I don't want things to be small for boot time reasons, but for security and simplicity reasons

user

Security?

ta Radvylf srik su shilani

Yes. The less code, the fewer bugs can hide in it.

user

Ah

ta Radvylf srik su shilani

Bloated, rarely used features are more likely to see less scrutiny and harbor really bad vulnerabilities

How many issues does unix have compared to linux?

BSD is close to Unix I think

user

MacOs?

ta Radvylf srik su shilani

That's based on Unix too yeah

But I'm p. sure it's not that similar
