The Nineteenth Byte

8:05 PM

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.

@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 :(

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

Google seems inconclusive

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.

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

8:09 PM

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

Oh. Then yeah, pretty slow ;)

"Fascinating" is the word you're looking for

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.

lol

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

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

8:16 PM

@Shebang x2 because they're RAID-0

The laptop as a whole was around $3800

Yeesh

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

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

@TimmyD The issue was using vim instead of VS

Yep.

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

The answer was obviously incorrect anyway.

8:27 PM

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

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

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

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

Please help, I installed SwiftKey and now I cannot type correctly >_>

@feersum If yes then the thing can't be answered without hard machine code hacks

;_;

@feersum Hmm. It says the cs file "generated by the IDE", so I guess not.

Wat

CLion don'y support Makefiles

still waiting for the day when computers automatically put the entire HD on RAM, and simply save it back on shutdown :)

8:30 PM

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

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

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

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

downloadmoreram.com RAM problems fixed

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

8:32 PM

Why would that be expected to happen?

@Geobits who need TB's of harddrive space?

25gb should be enough for anyone

oO

have you met any gamers?

8:33 PM

I have more than 25GB of photos I've taken. That's not even counting music, movies, games, etc.

Heck, I can name individual games that are more than 25GB

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

That's... not a problem.

Wait, so SwiftKey is forcing you to type with correct spelling?

Yeah, where's the problem?

ಠ_ಠ

The problem should be clear

You can't say "gaot"?

It's not. But your typing is.

It's starting to become clear, yes. But it isn't the typing.

Aww

@Downgoat get swype

@Downgoat Use Dasher

I never did like swype. The stock keyboard seems to work better than any of the third party ones I've tried.

Doesn't the Google keyboard have the same gesture typing?

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

8:40 PM

@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 ;)

yeah I mean in terms of word recognition though

@Maltysen that is only android afaik

@NathanMerrill That drops tomorrow, doesn't it?

@TuxCopter for keybaord?

8:42 PM

@Downgoat no, only android stock keyboard has it built in, but you can buy the third party keyboard for iphone too

@Downgoat Yes

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

@MartinEnder Oh. Mine does fine with that, but I don't swipe-type. I've never had issues with the word recognition/suggestions for actual typing.

Anonymous

@TimmyD So you and the other 3 people with Windows Phones can enjoy it :P

Yep. It's great.

8:44 PM

If your hands are just right, swiping works great. If they're the slightest bit sweaty, it's terrible. I live in Florida, so...

Unless you're moving to Arkansas.

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).

@Geobits They will be Google-contracted, not military-contracted. Slightly different.

Less chance of a court-martial

Seriously? Google contracts a mover?

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

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

@NathanMerrill That's what I would expect.

8:58 PM

at least, that's what they offered me

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

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

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.

@NathanMerrill From my understanding, it will either be that or a mover contracted by Google. Moving cross-country is a bit complicated :P

@Mego I thought that cities were the one part they hadn't figured out

9:05 PM

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

@quartata Creating huge security flaws

@quartata dynamic coding for newbs?

@quartata useful for evalling equations

@quartata would memcache storage fall under ast.literal_eval?

eval is one byte shorter than float

9:06 PM

@Shebang The best reason

eval() is fine, as long as its pure

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).

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

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

9:09 PM

@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.

@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.

@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.

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

9:16 PM

What are you trying to accomplish with that?

having quotes inside quoted args, basically

Only shells mess with that

yeah

That wouldn't be a problem with TIO.

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

should I just change the version used on TIO?

9:18 PM

Please.

maybe I'll just add a flag for it

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

and make default use regular args

@quartata nevermind

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

yeah, good idea. thanks!

I think I've caused you and TIO enough pain trying to get node on it :P

9:24 PM

@NewMainPosts I kind of wanted to do this in Retina, but padding the numbers is just going to make it annoying. Meh.

@ASCII-only Do you have a code page?

ASCII is only 7 bits.

Just was for a few seconds. Chromium is weird that way.

flawr

Speaking of browsers, I used to love firefox, but seems to have gotten worse over time, any other similar browsers you can recommend?

10:37 PM

@flawr Define similar

flawr

No

I'm learning about trichoplax right now

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.

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

flawr

I used to love firefox because of its speed and certain plugins and the flexibility you had, but it seems they restricted all those things in the last bunch of years.

Or else use Opera or Vivaldi (warning: both use Chromium)

Do you mean WebKit?

@Dennis No, Opera uses Blink (whoops nevermind), but Vivaldi is definitely Chromium-based

mınxomaτ

@ASCII-only Blink is Chromium.

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...

Blink is the engine, I thought Chromium was the actual browser

Ah, Blink is a WebKit fork. I knew I couldn't be that wrong. :P

mınxomaτ

10:45 PM

@ASCII-only If a Browser uses Blink, which is a part of Chromium, then it's Chromium-based in my book.

@mınxomaτ I wouldn't say that, isn't that like saying K-Meleon is Firefox-based?

WebKit/Safari/Blink/Chromium... it's all KHTML under the hood anyway. :P

everything is basically varying degrees of IE

Which is just Mosaic.

it's all just nice looking rock

@NathanMerrill normalization?

11:30 PM

maybe? google says that normalization has to do with vectors, and it normalizes it according to sqrt(a^2 + b^2)

but the rest of the process is correct

You normalized it according to the infinity norm instead of the 2-norm.

does that math actually work out?

@EᴀsᴛᴇʀʟʏIʀᴋ remind me?

Math terminology is not absolute. It's a type of normalization.

sqrt(a^2 + b^2 + c^2...) = a + b + c...?

11:32 PM

@NathanMerrill no

I didn't think so

@NathanMerrill sqrt(a^2 * b^2 * c^2...) = a * b * c

@DestructibleWatermelon no

Sep 26 at 13:49, by Eᴀsᴛᴇʀʟʏ Iʀᴋ
