Also, gave me a bit of a heart attack when you said corrupting memory and so immediately backed up the previous two programs I wrote last night for this class.

2018-03-31 21:40:51 UTC  

Valgrind is a VM that does memory checking, it can call gdb to debug a program that appears to be misbehaving.

2018-03-31 21:41:31 UTC  

Corrupting RAM; I imagine you're storing the code in a more permanent storage, no?

2018-03-31 21:41:43 UTC  

yeah, just gave me a freak out for a second

2018-03-31 21:41:50 UTC  

Is that code running in kernel mode? Or user mode?

2018-03-31 21:42:27 UTC  

I'm assuming user mode

2018-03-31 21:53:12 UTC  

Well either you're running it as a regular application under an already running OS, or you're chainloading it via grub during boot.

2018-03-31 21:53:55 UTC  

Okay, definitely the first one.

2018-03-31 21:56:02 UTC  

So what are you trying to accomplish? Reading a string and adding its bytes together?

2018-03-31 21:56:58 UTC  

read in five numbers, sum them, print result.

2018-03-31 21:58:20 UTC  

You're using `scanf` with `"%s"` though.

2018-03-31 21:58:25 UTC  

oh shit

2018-03-31 21:58:29 UTC  

I forgot to change that

2018-03-31 21:58:38 UTC  

lol

2018-03-31 21:58:43 UTC  

That's why I said, write the C code first.

2018-03-31 21:59:17 UTC  

I was using my previous one as a template because that also had a loop, and that was for a string.

2018-03-31 21:59:37 UTC  

I mean, I still have a segfault, but that would have caused other problems obviously.

@meratrix why more js

2018-04-01 21:19:59 UTC  

js should be left in a ditch

2018-04-01 21:20:04 UTC  

cause js is best bs

2018-04-01 21:20:04 UTC  

and never be talked about

2018-04-01 21:20:10 UTC  

JS == BS

2018-04-01 21:20:17 UTC  

Shitting on JS is the only way some JS programmers can cope with their job.

2018-04-01 21:20:29 UTC  

Keeps them from offing themselves.

2018-04-01 23:40:56 UTC  

@meratrix 👌

2018-04-02 00:20:00 UTC  

Then why do some JS coders spend so many time shitting on other lower level languages?

2018-04-02 00:29:53 UTC  

Cause everyone's got a salty side to them.

2018-04-02 00:49:48 UTC  

^

2018-04-02 02:00:04 UTC  

Because they don't know any better.

@Deleted User Still doesn't work, ugh. Please end my misery.

preferably with a bullet to the head,

2018-04-02 11:33:00 UTC  

@meratrix did they give you a book for this class?

2018-04-02 15:01:37 UTC  

Try harder

2018-04-02 15:02:45 UTC  

git gud

2018-04-02 20:46:41 UTC  

I do have a textbook, but it doesn't go over specifics, just the general instruction set, and it's mostly computer architecture, there's one chapter on assembly

2018-04-02 20:47:13 UTC  

It seems to be summing the addresses instead of the values themselves
