evening

Nathan Osman

Good evening.

IanC

how are you guys doing tonight?

Nathan Osman

Fine. And you?

Serg

me， i'm getting a bit sleepy. . . . was working on my dynamic_mouse_speed.py script till 2 am yesterday

IanC

good, just getting back at the C learning, trying to go fast and get sooner to the more intermediate stuff :)

want to start programming sockets

but first review and relearn the fundamentals of C

Serg

12:20 AM

I should get back to C as well. As electrical-engineering student, I need it for microcontrollers and stuff like that

IanC

you guys can recommend any really really light linux distro to use as a VM?

I want to make some networking tests in virtualbox, but a regular distro usually takes up too much RAM, just wanted a distro with X-server and basic networking functionalities

to simulate at least a 3 computers LAN network

Nathan Osman

PuppyLinux is a good choice.

Serg

@IanC any distro will do , really, as long as you don't use GUI. When you wanna use light GUI , you could go with lubuntu, xubuntu, puppy linux ( i have it on USB) , freebsd with a GUI of your choice is OK. MATE is also quite OK.

edwinksl

this answer is so wrong i am facepalming hard askubuntu.com/a/808103/15003

Serg

Deepin is very pretty , but can be a bit laggy with gui

i think im gonna write a window-arranger script. Over time, people have been asking on AU for script to do 1/3 of a screen, 3/4 of a screen , etc. I wanna put it all into one script so that one could rearrange windows however they want

IanC

12:27 AM

cool, think I'll try puppy linux

CodeX

Question : is it possible to run chrome without any DE ?

IanC

DE?

CodeX

Desktop Environment

edwinksl

@CodeX yeah of course, how did you think people using WMs surf the interwebs? :P

CodeX

@edwinksl oh .. so do you think it will save much power

edwinksl

12:32 AM

it will save power yeah since DE consumes resources and fewer resources consumed = lower power footprint

but not sure how much

CodeX

@edwinksl hmm thanks .. will test it

edwinksl

sounds good

IanC

12:46 AM

just downloaded puppy linux, going to test it as soon as I finish some of the C lessons :)

Serg

1:00 AM

speaking of testing, need to fire up my MATE vm and

. . . . maybe finally edit my answer for the lks-indicator

which is overdue by weeks already

$ VBoxManage list  webcams
Video Input Devices: 1
.1 "TOSHIBA Web Camera - HD"
/dev/video0

There must be a way to expose my web-cam to virtual machines

mkay, imma go smoke and probably lie down

Zacharee1

STAHP SMOKEZ

Henry WH Hack v2.0

I think Serg is addicted to smoking. :(

Zacharee1

what an astute observation

edwinksl

lol

Zacharee1

I mean, wow, someone addicted.. to one of the most highly addictive substances?

not common

Henry WH Hack v2.0

1:14 AM

I'm addicted to stackexchange it's like Jeff Atwood MindControl (Help Me!). :D

IanC

man, pointers are a simple concept, but can get really complicated

Zacharee1

pointers?

edwinksl

char * zacharee1

IanC

yeah, in concept it's simple:

//Say you have a string in memory, a sequence of chars ending in '\0'

char *string[]={"String1", "String2"};

CodeX

Lol

IanC

1:17 AM

this is fairly simple to understand, there's a place in memory with the chars, and you just point to the address of the first char

Zacharee1

k

IanC

gets complicated when you have pointers for pointers

I mean, I can get the idea, but can't see what's truly going on in some situations

CodeX

Point is.. where is your Pointer Pointing

Serg

@IanC pointers are complicated - they're like translation between C and assembly. There's concept of pointers in assembly too

Black tea seems to really help with easing down on throat and stuff , especially for heavy smokers like myself

IanC

@Serg I would say raw assembly is even beyound that since you have to create a concept of variables yourself, you just have the memory addresses and have to worry about allocation, accessing it, changing it, so you will basically have to deal with addresses all the time

CodeX

1:27 AM

so your plan is to die early @Serg

Zacharee1

^

IanC

but I don't think no one makes programs in raw assembly, I've seem some assemblers where you can create variables by giving them a name like in higher level languages

Serg

@CodeX no, my plan is to slowly stop smoking, but so far I'm not stopping

CodeX

@Serg you might need to reprogram your unconscious mind to help you stop smoking

edwinksl

we are going to need a direct channel to your gf so we can tell her to tell you what to do :D

Seth

1:29 AM

@HenryWHHackv2.0 the nice thing about Stack Exchange is that it becomes so addicting it unaddicts itself after a while

Serg

@IanC lol , some professional hackers and engineers can write pure assembly programs. Or those people who deal with embedded devices. But it really is a pain in the lower body. We've been doing simple while loop in assembly on pic18 microcontroller , took us like 45 minutes

Seth

(I totally just made that word up :D)

Serg

@Seth nah, so far it hasn't unaddicted me. It actually is quite bad sometimes. Doing AU stuff instead of homework

IanC

@Serg yeah, assembly is crazy stuff, I've studied the basics of it a long time ago. You have to reinvent the wheel all the time

Seth

I didn't say it happens over night.

IanC

1:31 AM

conditionals, loops

Serg

@edwinksl hack my wechat and you'll know :p

IanC

it's all on your hands, you just have the memory and the processor to play with hehe

Henry WH Hack v2.0

This is my second vtc post :) Hold up on area 51 why can you vtc at 150 reps weird?

Serg

it really depends on a processor. If it's ARM , you'll have more tools than on motorolla 68k

pic18 is also different from others since it kind of has working register

IanC

I just studied x86 ASM, shouldn't the basics be the same? Like the registers and basic memory/processor interation? thought the major change would be the interrupts (and registers size in case of different architetures)

I wish I knew where my assembly book was, guess I'd make a much better use of it today

back then I didn't understand some things like I do today (and I still feel I'm far from getting everything right)

Serg

1:37 AM

yes, register size differs, but also instructions differ. ARM has many instructions which can be treated as if then else if statements. I mean, that's why people like ARM a lot. What also differs is that 68k allows you to access memory directly, but ARM doesn't. you have to copy values into register first, then operate on things, and store back.

CodeX

I didn't get the concept of area 51

Serg

@IanC honestly, i feel about the same. I regret that i didn't study programming earlier and better. I feel like i lost a lot of time in my teen years and now i am only starting to catch up

But i had no computer back then either......sad

actually , even after i got one, i didn't start right away.

IanC

@Serg Well, if it makes you feel better, I think you're a good way ahead of me :p

but it's never too late to learn

I'm diving full speed into networking protocols, reading some C coding

readed a bash book to understand linux a little better

(linux shell)

Serg

i should go into networking a bit too. It's still very shaddy area for me. But as of right now, i do lots of python

Q: How can I not default to root on the new Ubuntu on Windows?

When I open the new bash shell on windows, I'm greeted with root@[computer_name]:/mnt/c/Windows/System32# I'd rather not login as root by default, nor would I like to start out in System32. That seems like a horrible recipe for disaster. What's the best way to default to a different user (I've...

Serg

1:44 AM

Speaking of C . . . .since i am doing a lot of desktop programming lately, maybe i could do some C code for X11 stuff. Or even Gtk

IanC

nice, I'd like to see some of those codes :)

might sound like a stupid question, but is X11 the X-Server running on ubuntu?

Serg

yes

IanC

is it responsable for the GUI and all input/output (mouse, keyboard, sound, etc)?

I get a little confused because if X11 is responsable for the GUI, where does GNOME and lightdm play? are they part of X11 or maybe used by it?

Serg

GUI and input devices. Sound can be managed by other things

lightdm is just login screen. that's all. Gnome is what makes windows pretty

if you use something very raw, like 9wm, you will see it has no decorations

just plain square window, no frame and no buttons

gnome and compiz are also responsible for workspaces

on plain desktop environment like motif or 9wm there is no workspaces. Just one desktop

I have bunch of other desktop environments and sometimes use motif or blackbox or openbox. I like the classic look and feel they give to my desktop

IanC

isn't lightdm also responsable to make the windows and GUI more pretty? Thought that's why you had to "remove" it to install GNOME. So they will basically interact with X11 to expand it?

Serg

1:58 AM

yes, they expand on basic x11 functionality

You don't have to remove lightdm to install gnome, by the way

IanC

thought they conflicted, nice to know

Serg

Gnome has its own gdm, but it's not required. i cam use either one separately from each other

You know, 10, even 5 years ago i could not image that I'd be discussing bunch of technical stuff with people in AU chat and doing bunch of scripts for moving around windows and stuff.

a lot has changed really

IanC

you took the red pill

:D

Serg

2:15 AM

Yup, i did. I sure wish it happened earlier though

IanC

how old are you?

Serg

26 as of this July

And you ?

IanC

lol, I had to check which year we are in

I'll turn 23 november

you're young dude, plenty of time to learn and become a linux guru :p

Nathan Osman

I also recently acquired the age of 26 :D

IanC

happy late birthday!

Nathan Osman

2:26 AM

Thanks.

Serg

Yeah, there's plenty to . I just tend to look back on paths too much and stuff.....And there's also the whole peer pressure and parental critique and blah blah......

IanC

pressure on what you mean? career?

Serg

2:44 AM

pretty much. All my ex classmates graduated, have jobs and families. I'm still im college and without any serious job or possessions

i know it'll come with time, it's just that the world moves much faster than i do

Q: were my ubuntu hacked?

Sorry my grammar I'm from Brazil. I see my ubuntu today night and my computer name changed automatically for "localhost" my ubuntu is freshly installing.I only installing "sudo apt-get install myspell-pt-br" And I already activated my firewall. My ubuntu is 16.04.1Lts desktop. was I hacked? thank...

scripts hacking

Somewhat funny. localhost == hacked

Zacharee1

3:00 AM

were it?

IanC

@Serg don't worry about this stuff, just live the way you want to live. My ex classmates are probably working in chemical engineer industries, going through the expected path, and I decided to move to the coast and work mooring boats. I'm happy here

and I don't think I made a bad call, I just made MY call. So if you believe what you are doing is what you want for yourself, I don't see why care too much about those kind of stuff

IanC

3:11 AM

well, I think I advanced a good bit, next lesson "Stack and Heap allocations", I was just about to research it :p

Nathan Osman

This is gold: m.reddit.com/r/totallynotrobots/comments/4w4lnk/…

Serg

I made my own choices too. At first when i chose electrical - engineering I was slightly miserable but i like this stuff more and more. But I really get excited by programming. That's why I spend so much time scripting on AU. I mean, I am not much of a hardware guy, more interested in software and coding. And while it can be challenging, it brings me satisfaction

IanC

then just keep doing it, what are you graduating in right now?

(gotta update the other distro, brb)

Serg

Well , I don't think I'm gonna be graduating any time soon, I think I need like 2 more years. I failed a lot of classes, so it took me long time to get back on track

Serg

4970 × 3313 image . . . uh . . . i dunno if my desktop can handle it

How's that ?

CodeX

Looks cool

mine I can't show because it is full of note widgets

ƎpᴉʇʎXD

unless you got a freaking 4K SAMSUNG SUHD TV as your monitor

Serg

3:36 AM

@CodeX by the way, how's the script working ? just making sure if you're satisfied with the performance and stuff like that

@CodeX you can always hide icons, there's an option for that

command actually

ƎpᴉʇʎXD

chineese ?

@ƎpᴉʇʎXD chinese what ?

@Serg ok will try that

tea time ..brb

Serg

@CodeX what kind of desktop are you using ? Looks familiar but can't put a finger on what exactly it is. Blackbox ?

oh, sorry, go ahead

CodeX

@Serg Kde

Serg

KDE ? I thought it had start menu with K button , like start menu in windows

Does look pretty though

CodeX

Kubuntu .. I customized it

Serg

3:43 AM

Ah, I see

well good job , looks really pretty. Kind of like a cross between chrome desktop and blackbox desktop

Nathan Osman

It's better than Gnome. But then again even GNUstep is better than Gnome.

Serg

I'm content with Unity so far (especially since i am on SSD and 8 GB of RAM). Unity is pretty and has enough functionality of its own. If I need something lightweight - openbox or blackbox. But that's just me.

CodeX

4:03 AM

hmm I never heard about blackbox .. does it have something to do with airplane xD

Serg

:3 nope, no airplanes at all.

CodeX

I like this time widget .. sync's with google calendar

Serg

and it even has weather update

CodeX

yeah now that I have advertised you should switch to kubuntu xD

Serg

Mmmm, maybe not entirely . . .I'll get Kubuntu VM for sure though

CodeX

4:09 AM

cool
