Wait who can protect questions?

Mendeleev

@WheatWizard mods I guess?

Wheat Wizard

This question was protected by a non-mod non-community user

Mendeleev

I think theres a rep thing

ATaco

5:06 AM

You can protect at 3,500 Rep.

Wheat Wizard

Oh wow, then I can protect questions

DLosc

@ATaco Is there some other condition too? I'm not seeing the place to click.

Mendeleev

...I just wrote "laptop" as "altpop"

fml

Wheat Wizard

Yeah I don't see any button myself

ATaco

That's all I know.

Wheat Wizard

5:08 AM

You can click on that to bring you to the privedges page where they have more info (I can because I got all the privledges ;_;)

DLosc

Aha: The question must have at least one answer by a user with < 10 reputation on the site.

Figured it might be something like that.

Also, the privilege comes at 15,000 rep on fully graduated sites.

Wheat Wizard

Oh man I need to get more rep before we graduate

DLosc

I was just about to say, "Guess I need 2500 more before graduation" X^D

Wheat Wizard

I just need to hit 10k so I can keep my review access

I really don't care about site analytics

Kritixi Lithos

For a moment there, I was excited that we graduated

Phrancis

5:26 AM

Speaking of graduation, what's the latest news from SE for this site?

betseg

I...just...what?

Ashwin Gupta

@betseg what language?

betseg

JS

Ashwin Gupta

I knew JS was broken.

I didn't know it was that broken

does >= compile to the same thing as if(null>0 || null == 0)?

because it could be a bit thing based on how it compiles

or is interpreted*

78

Q: Why `null >= 0 && null <= 0` but not `null == 0`?

I had to write a routine that increments the value of a variable by 1 if its type is number and assigns 0 to the variable if not, where the variable is initially null or undefined. The first implementation was v >= 0 ? v += 1 : v = 0 because I thought anything not a number would make an arithmet...

betseg

It seems ( a >= b ) is defined as !( a < b )

Ashwin Gupta

5:34 AM

@betseg probably

bad design, is that just chrome? FF and IE use different JS interpreters

betseg

ES designed it that way :(

Saw a link in Reddit to some ES guide

Ashwin Gupta

damn, they must've done that for a good reason though.

ATaco

@betseg Not true in all cases it seems.

Ashwin Gupta

Just to save code I assume

@ATaco example case to counter?

ATaco

a=function(){};console.log(!(a<1)==(a>=1))

Phrancis

5:37 AM

If you're comparing null with greater & lesser signs, you're probably doing something wrong regardless of the language

betseg

Is it true?

Ashwin Gupta

@Phrancis fair enough

@betseg no false

betseg

@Phrancis well in c you're just comparing with 0

Ashwin Gupta

@Phrancis but what if I need to know if(null>null+1)????!?!??!?!?!??!?!?!?! :(

interestingly enough, JS considers null+1 =1

betseg

Plz feed me with more information, I'm on mobile and have no console :p

Григорий Перельман

5:39 AM

@AshwinGupta Because == is itself borked

===?

ATaco

null < null+1 and !(null > null+1)

For the curious.

console.log(null<null+1, null>null+1)
 true false

Phrancis

Since JS can't afford to crash the browser or web page every time it encounters something unexpected, it has to play fast and loose with some things

betseg

Makes sense

Ashwin Gupta

help me out here, I'm a linux noob: I've downloaded a microcontroller (MSP430) GCC compiler onto my rpi, where should I place such a thing?

like good practice: where in the file system? Certainly not the desktop.

ex: in windows I'd put software under Program Files (x86) or Program Files for x86-32 and x86-64 bit applications respectively.

Григорий Перельман

The equivalent of Program Files on Linux is /usr/local/bin/

Ashwin Gupta

5:52 AM

@ГригорийПерельман ty

Григорий Перельман

Technically there's multiple directories like that, but /usr/bin/ should only be modified by the package manager and /bin/ should be things that come with the system.

Ashwin Gupta

@ГригорийПерельман oh wait no this GCC version I'm installing manually through compiling source

so i shouldn't put that in /usr/bin. Where do i put it then?

betseg

Still /usr/local/bin

Ashwin Gupta

oh I see /usr/local/bin vs /usr/bin

got it

thanks

betseg

But still check if the variable $PATH has /usr/local/bin/ in it

Ashwin Gupta

5:56 AM

@betseg i'll add it if it doesn't

Kritixi Lithos

-f    If the destination file cannot be opened, remove it and create a
           new file, without prompting for confirmation regardless of its per-
           missions.

Ashwin Gupta

@KritixiLithos yeah Ik I just manned it

not the end of the world, it found the file

Mendeleev

6:11 AM

I have officially started Pre-Calculus

betseg

But does it include calculus?

:p

ATaco

Pre-Calc? Oh boy.

If you don't already hate graphs you will now.

Right up until the point where you realize everything makes sense and is sort of beautiful in a way. If you don't hit that point god save you.

DJMcMayhem

6:26 AM

I enjoyed pre-calc a lot

Григорий Перельман

The first semester was review of Alg 2, and the second semester was entirely Trigonometry

¯\_(ツ)_/¯

Kritixi Lithos

We're starting calculus next school year

betseg

We too

Григорий Перельман

We? Who exactly are you speaking for?

Kritixi Lithos

My class

Григорий Перельман

6:29 AM

I'm taking Calculus next year too, eh.

@KritixiLithos Oh, for us we all take math classes in whatever order.

So I'm taking Stats now but took Precalc last year

But the people I took precalc with are mostly in Calc now.

Kritixi Lithos

The teacher decides the order for us. Right now, our unit is statistics

Григорий Перельман

Oh, for me Stats is a class, not a unit.

I suppose different places have different systems

betseg

The government decides our order :D

Григорий Перельман

Well, there is some order. I can't, for example, take calc before pre-calc.

But if I really wanted to, I could take a test and waive the requirement.

Kritixi Lithos

@KritixiLithos Wait, I think the IB decides the order for us, not sure

betseg

6:35 AM

@betseg and they change the order every year

Mendeleev

@ГригорийПерельман I see you have a similar program to mine

Григорий Перельман

It's standard across most of the United States if you're in a public school.

Mendeleev

@ГригорийПерельман No, I mean the online/choose your own class thing

Григорий Перельман

Well, considering we live in the same county

Mendeleev

Well, in a traditional high school, I would be sitting in an actual classroom...

Григорий Перельман

6:49 AM

Oh, right, I forgot you did that.

Mendeleev

Your school does it similarly to mine, where all classes are online and can be completed as needed

Григорий Перельман

No, most classes are not online, but you can take them online if you want to fulfill a requirement for a more advanced class.

Mendeleev

I see

Григорий Перельман

That's normal.

Mendeleev

Oh, OK

$user image$

$300^{google.com}$

OK, that broke the userscript @ATaco

DLosc

7:01 AM

@Mendeleev Nonsense, beautifully typeset

Mendeleev

@DLosc No, the second one, ChatJax chokes on that

Like, usually I can $\LaTeX$ and it's fine

It just gets rendered by $ChatJax$

DLosc

I was afraid you would misunderstand me. I meant that 300 to the power of google.com is nonsense, but with LaTeX it still looks beautiful.

ATaco

I can't test from here, on my phone.

Mendeleev

@DLosc Oh, I see what you mean now.

DLosc

Should've gone with Beautifully typeset nonsense

Mendeleev

7:07 AM

@DLosc yes

Matthew Roh

Wait, LaTeX in chat?

Mendeleev

@MatthewRoh You have Tampermonkey, right?

Matthew Roh

@ГригорийПерельман Yeah, I do

Григорий Перельман

Yeah, with those three links you get syntax highliting, chatjax, and commands.

Commands are /tableflip and the like replaced with emoticons, for the full list you need to look in the code.

Matthew Roh

So, basically discord chat commands in SE chat?

Григорий Перельман

That was the original inspiration, in fact.

Also, /$\LaTeX$ inserts the $\LaTeX$ as an image so people without the script can see it.

Matthew Roh

o_o

Григорий Перельман

7:52 AM

No, /o_o

Matthew Roh

Григорий Перельман

Huh

I think you need to refresh chat

Matthew Roh

okay..

Q: Make a 'Logical' interpreter

'Logical' is an esoteric language I am working on. It involves 4 logic gates, AND(&), OR(|), NOT(!) and XOR(^). Since only having 4 logic gates, the IO is only true or false (We are not discussing Qubits here :P) It will have some lines in the format [input 1] [(not included in not gates) inpu...
