Q: C# is the Main problem

This programming puzzle is inspired by another question which has been asked here yesterday but which was deleted by the author... The challenge: Create an executable binary (Windows .EXE or Linux binary) file which prints the following text to the standard output: Main() is the main method of...

c#

TimmyD

Speaking of computer hardware, these things are ungodly fast. My new home laptop has two of them in RAID-0 for the boot drive, and from powered-off to usable Windows desktop is around 1.5 seconds.

TuxCopter

@TimmyD I remember upgrading my laptop from an hdd to a 512gb samsung ssd. So much speed. Then I switched it over to my desktop, so now my laptop is slow again :(

quartata

Does anyone know if gcov handles #line properly? I figured I'd ask before I tried a simple test

Google seems inconclusive

TimmyD

I've been using SSDs for boot volumes (at least) for around four or five years now. And the other day, I had to actually boot up an old machine that had a pair of WD Raptors in RAID-1 for the boot. Holy cow, it was like watching paint dry.

I've become spoiled.

Geobits

So, really fun and engaging? I love watching paint dry.

TimmyD

20:09

I was going more for the time aspect. Not necessarily the engagement aspect.

Geobits

Oh. Then yeah, pretty slow ;)

quartata

"Fascinating" is the word you're looking for

Geobits

But the time flies since you're having so much fun.

It's way better than watching grass grow, at the least.

That might have something to do with fumes though.

TuxCopter

lol

I answered codegolf.stackexchange.com/q/96772/53745 but it's non-competing because I used vim

Shebang

@TimmyD Your boot drive costs more than my laptop :(

TimmyD

20:16

@Shebang x2 because they're RAID-0

The laptop as a whole was around $3800

Shebang

Yeesh

Yeah, I meant your whole RAID-0 'drive' cost more :P

TimmyD

@Tux Language-specific challenges are allowed, provided that they feature a challenge unique to that language, which this qualifies.

DJMcMayhem

@TimmyD The issue was using vim instead of VS

TimmyD

Yep.

Was getting to that part - trying to find the meta on that.

feersum

The answer was obviously incorrect anyway.

TuxCopter

20:27

Correct about their rule (except the IDE one) if I read correctly

Geobits

Yeah, I'm no C# expert, but I'm fairly sure the unicode escapes would compile to the banned letters.

TimmyD

> Marking an answer as non-competing does not exempt it from being invalid.

feersum

Wait... does the banned string rule apply to the executable?

Geobits

20:30

@Downgoat SwiftKey doesn't fix hoof problems, and I don't know why you thought it would :P

Nathan Merrill

you'd need some sort of reserve power to give it time if the power suddenly dies

feersum

@NathanMerrill Won't happen because software and media expand to to fill the available space :)

Geobits

RAM is cheap nowadays, but it isn't "put a couple TB in your PC" cheap.

all you need is for RAM price per GB to be the same as HD price per GB

Downgoat

@Geobits no, I meant that I cannot type "p l s h a l p" anymore

Geobits

Maltysen

@Shebang yeah, I just use that now, I meant the concept more than the product

Martin Ender

@Geobits apart from how insanely slow Swype was, I thought it actually worked better than the stock one

Well, "insanely slow" was a big part of it ;)

@Downgoat Yes

TimmyD

I'm not sure if it's explicitly Swype, but Windows Phone has that style keyboard built-in.

Moving is especially fun when all you have to do is pack and unpack boxes

Definitely. Even better when you don't even have to do much of that. The military-contracted ones would tell you not to box anything up, so they could do it themselves (liability and all that).

Less, but not by much. I never heard of anyone getting court martialed for boxing their stuff up.

@feersum I believe they give you money to get a mover

feersum

If you box up your stuff, does it have to be put in another layer of boxes?

@NathanMerrill That's what I would expect.

Nathan Merrill

20:58

at least, that's what they offered me

Geobits

@feersum No, they'd usually unbox it in front of you and rebox it.

Conor O'Brien

@feersum ...and put that box in another box...

Geobits

And get pissed while doing it (for obvious reasons).

ETHproductions

@Geobits No, they just toggle whether your stuff is boxed up. If it is boxed up, they ship it out without boxes.

Poll(ish): Aside from evaluating numbers and strings (a la ast.literal_eval) can anyone think of good real world use cases for evaling a string

@Mego I had just gotten that song out of my head

TuxCopter

@quartata Creating huge security flaws

Conor O'Brien

@quartata dynamic coding for newbs?

Nathan Merrill

@quartata useful for evalling equations

Maltysen

@quartata would memcache storage fall under ast.literal_eval?

Shebang

eval is one byte shorter than float

TuxCopter

21:06

@Shebang The best reason

Nathan Merrill

eval() is fine, as long as its pure

quartata

It's a pain in the ass to transpile.

to say the least

El'endia Starman

It could be left out of the transpiled stuff until later (if it's ever included).

Maltysen

question: what's the best way to show someone a math proof online? sketchboard.io kinda works

quartata

True but it just got me thinking if there's any point at all

Maltysen

21:09

@quartata wouldn't literaleval be harder than normal eval?

El'endia Starman

Well, one of the guiding ideas for Pytek was to make it more flexible/stronger/abstract so that more can be done with it. I think \eval contributes towards that. It doesn't have to be implemented right away, but I think it should be implemented eventually.

quartata

@Maltysen literal eval just requires some parsing, eval requires linking the entire interpreter in the case of a standalone executable target

@El'endiaStarman bahh I know but I'm lazy ;(

Well anyways we have bigger fish to fry for now

El'endia Starman

@quartata Yeah, like a borked parser.

Dennis

@ConorO'Brien Um, sure, but how would they be delimited? Ideally, it should take the arguments as arguments. If somebody knows how the interpreter works locally, it should be straightforward to execute the same program on TIO.

Conor O'Brien

@Dennis well, I want to parse the arguments without having the auto-parse of the command line

Dennis

21:16

What are you trying to accomplish with that?

Conor O'Brien

having quotes inside quoted args, basically

quartata

Only shells mess with that

Conor O'Brien

yeah

Dennis

That wouldn't be a problem with TIO.

Conor O'Brien

but that's how I'd be doing it locally, to circumvent shell processing

should I just change the version used on TIO?

Dennis

21:18

Please.

Conor O'Brien

maybe I'll just add a flag for it

quartata

so just use single quotes and stuff when you're calling from the shell and don't worry about it anywhere else

Conor O'Brien

and make default use regular args

@quartata nevermind

Dennis

That would be the easiest option. -af <arg-file> or something like that.

Conor O'Brien

yeah, good idea. thanks!

How similar would you count as similar

Firefox became more and like Chrome lately, so I guess Chrome is technically similar. However, since you think it got worse, you probably won't be happy with Chrome as well.

ASCII-only

If you mean Gecko-based, maybe K-Meleon would work, also Waterfox, Lunascape, Pale Moon or Conkeror

Blink (web engine)

Blink is a web browser engine developed as part of the Chromium project by The Chromium Project with contributions from Google, Opera Software ASA, Intel, Samsung and others. It was first announced in April 2013. == Engine == It is a fork of the WebCore component of WebKit and is used in Chrome starting at version 28, Opera (15+), Amazon Silk and other Chromium-based browsers and frameworks. Much of WebCore's code is used for features which Chrome implements differently (such as sandboxing and the multi-process model). These parts were removed from the Blink fork, which made it simpler, and gave...
