@Dennis Brain-Flak TIO is borked

Kritixi Lithos

Hello! This is The Name of All that is Good and Holy. Before you think of making your own extension to this language, here's another idea for you to consider: Don't! For the love of me, please don't make another derivative of this language!

^^ That's from BF's esolang page

brb, making PowerShell-like BF derivative.

Noooooo

TIO is borked is not a bug report. It's hardly even English. Please tell me what you're trying to do, what you expect to happen, and what happens instead.

Why did the offensive flag count show 0 when there was a flag?

Fun fact: the snippet I posted is almost valid PowerShell.

So you created BrainShell

7:09 PM

I kinda like the other amalgamation better.

@muddyfish Handled right away

muddyfish

But I could still handle it though?

@Dennis Pretty sure that would get flagged as offensive ...

@Dennis Powerflak?

7:10 PM

@TuxCopter @(1|%{}|?{})[@()] is valid PowerShell.

What does it do

@TimmyD No idea what you mean. the other amalgamation is completely innocuous.

It's a no-op visibly

Or are we talking about the other BF

github.com/betseg/Alphafuck/wiki/Commands is dis look nice

7:13 PM

@TuxCopter It takes 1, feeds it into a ForEach-Object empty loop |%{}, feeds the output of that into a Where-Object clause |?{} but since the clause is empty, no elements will result in a true clause and thus nothing is selected. That's encapsulated in an array wrapper @(...), and then indexed [...] with the index being an empty array @(). Results in no output.

dat name

@muddyfish When a chat flag is raised, 100+ 10k users storm at it at once, think about it for the fraction of a second, and raise a flag or a counter-flag. If the original flag just got dismissed as invalid, the counter drops to 0. If you click it after that but before the next 10k user clicked valid (effectively creating a new flag), the situation you describe could happen.

Hmm.

It has a driver, as is evident by the keyboard working after that prompt. However, this prompt for some reason doesn't load keyboard or USB drivers.

@mınxomaτ Does the mouse input work? Can you get to the accessibility wheel in the corner?

No input works during that prompt. Not mouse, keyboard or anything else.

I only get past that with a broken unattend.xml. However that doesn't actually give any option to switch to manual install. You can just click "OK" upon error.

I've patched the binary. So far so good, I got past the prompt.

Lenovo must be doing something pretty unique with their keyboard, because USB HID is at this point just about as generic as VGA graphics (i.e., everything supports it).

The $50 for a recovery stick is insane, too.

@TimmyD They employ proprietary driver where they can. Remember that Lenovo laptop that didn't support linux, because they used a locked-down HDD driver?

@TimmyD Yeah, $50. That's about two Windows licenses and a dozen of USB drives.

Wow, Java 8 lambdas are terrible.

int i = 0;
...
() -> { return i++; }

Requires i to be final.

I mean, I know they're just syntactic sugar for anonymous classes

and anonymous classes can't do that either

But don't advertise them as allowing for functional programming when they can't do the most basic closure trick

You can increment a final variable??

No, of course not.

That's the point.

It doesn't really have access to the variable. It has a copy.

That's why it requires it to be final.

Length-1 int[] to the rescue!

Yeah, that's what I'm doing. But it looks hideous.

Mach (kernel)

Mach (/mʌk/) is a kernel developed at Carnegie Mellon University to support operating system research, primarily distributed and parallel computing. Mach is often mentioned as one of the earliest examples of a microkernel. However, not all versions of Mach are microkernels. Mach's derivatives are the basis of the modern operating system kernels in GNU Hurd and Apple's operating systems macOS, iOS, tvOS and watchOS. The project at Carnegie Mellon ran from 1985 to 1994, ending with Mach 3.0, which is a true microkernel. Mach was developed as a replacement for the kernel in the BSD version of Unix...

clang is just a thin layer on top of LLVM. GCC is a collection, not a compiler. G++ is a compiler of GCC.

Stupid Internet.

Almost all of the BSD code is gone though.

~~bad-connection?~~ bad-connection.

Very very few components are leftover from 4.3BSD

The architecture is completely different since it's a microkernel too.

Actually clang is a wise choice for OS X. Since LLVM has the most actively developed and tested optimizers and code generators. There's a reason Google, MS and Apple are all contributing to LLVM.

Plus I find LLVM has some really nice front-end tools. Like refactoring for C++

@Dennis really random but you should totally learn J :P

And APL.

Despite cracking some C&R answers in J, I still don't have the slightest idea how to parse anything other than a string of verbs.

Oct 5 at 21:50, by Dennis

I basically created Jelly because I couldn't figure out J. :P

Actually, the Jelly documentation was total gibberish to me to, when I first looked at it.

But it fortunately has non-obfuscated source.

It was somewhat helpful after I figured out the basics.

Yeah, reading J's source code is a C&R challenge of its own.

@feersum what? J has great documentation.

hi @Dennis

o/

._.

throw new Exception;

so miles's verb is a 5-train; the first two verbs in the train obtain the first axis from the result of the right verbs. The right three verbs form a fork; the argument is passed to the left of the inner tine; since the inner tine is a bonded expression, it repeats it (left arg) times over the right arg. This is the basis for our repetition of lucas numbers. The inner tine takes `1` as a left arg, and the initial seed as right arg. The inner tine is a 4-train, which creates a list (prev_list, sum), then chops the first element from it, with `1}.`, giving the next pair of lucas numbers.

"lucas numbers"?

@ConorO'Brien miles' verb*, no?

@feersum yeah. if the left arg was 3, it would repeat it 3 times

@TuxCopter no. that pluralization is reserved for more historical figures

Which verb means to repeat something?

I thought bond was like currying

k. I should stop trying to correct english haha

I should learn about gpu coding properly one day.. this might be an excuse

@feersum it is. but since all verbs are at most dyads, it doesn't make sense to have a triadic expression, so a different behaviour is defined.

see here, right side

x m&v y ↔ m&v^:x y
x u&n y ↔ u&n^:x y

10:14 PM

@ConorO'Brien Well there's one mention of repeating: The phrase x f@[&0 y is equivalent to f^:x y , apply the monad f x times to y .

It's unclear whether this is a separate definition of &, or some behavior that falls out of the basic rules and interactions with the other gibberish there.

Eᴀsᴛᴇʀʟʏ Iʀᴋ

For the CS:GO players

@Javadoub it's J. ↔ is an equivalence marker which has no meaning in J

@Javadoub maJik

What is the purpose of the 0? To get this behavior do you need to bond with a 0, or can you have any dummy object there?

@ConorO'Brien Huh. I expected the right-hand box to be a symbolical restatement of the verbal explanation in the left -hand box, but instead it is a completely separate definition!

Like, sense 1 is on the left, and sense 2 is on the right, correct?

@feersum yup! more specifically, monadic on the left, dyadic on the right.

The highly divergent styles of the two boxes which each perform the same kind of function makes it appear that they are performing two different kinds of function.
