@Serg this solution will work for computers with the default ubuntu font (which I think is your aim), but if your indicator gets installed on a computer with some other default font that is not monospaced, it might show some offsets because maybe the spacing isn't the same I think

but well, you could use the tab indenting on computers with the ubuntu font and just disable it on computers with other fonts

Serg

@IanC and that's why I am going to have two functions ;) one for default font and the other for non-default

IanC

cool, should be alright then :D

Serg

Mmmm, i so wanna have VGA splitter right now. My left side feels lonely

David Cole - Grammar Police

00:23

Yo guys

Anyone good with the way programs utilize the internet?

Because MEGA is downloading at 300 kbps

But my internet provides 60 mpbs...

If you got any insight, ping me

Serg

@DavidCole-GrammarPolice there's nothing like that, ie you can make a program download faster, because the TCP protocol is build that was - it adjusts to your link speed

I'm actually studying that right now

David Cole - Grammar Police

Wait so it's intentionally downloading at like 0.05 times what my max is?

Seth

@DavidCole-GrammarPolice There are 2 computers involved in a download. Yours, and the server. You can only download as fast as the server serves the file.

David Cole - Grammar Police

Hm.. I've sen faster speeds from MEGA though, doesn't seem normal to me @Seth

Seth

@DavidCole-GrammarPolice iirc MEGA is a file sharing service? There can be a number of different reasons the speed fluctuates.

David Cole - Grammar Police

00:29

very true, but would it be anything on my end?

IanC

some programs can download faster though by eliminating some overhead of robust protocols like TCP, like using UDP or the T/TCP. But in the endgame the link speed (as @Seth said, influenced by both the nodes of the connection) will limit the speed

David Cole - Grammar Police

or is it too hard to tell?

IanC

and ISPs in some countries sell the internet with a advertised speed and deliver the minimum they are obligated by law

Serg

@Seth kind of. Server will detect if there's congestion on network and trim down value of packets by half at the point of congestion. so if server detected there's congestion at 50 packets, it will drop down to 25 and try to ramp up with every ACK

Seth

@Serg no, I mean many download servers throttle their speeds.

Serg

00:31

@Seth right, they throttle exactly to avoid congestion

@IanC UDP is not reliable though

David Cole - Grammar Police

IanC

for some services it is reliable enough, if you don't need to check that every data arrives

T/TCP is reliable though, and eliminates some overhead from common TCP

Serg

well, for data transfer it better have all data arrive. You don't want customers complain about corrupted files all the time

If it's video or audio, dropped packets here and there are ok, missing milliseconds of video ain't big deal, but files do require reliability

IanC

that's what I mean't by some services, I was going to use live video streaming as an example

for data transfer reliability is obligatory indeed

Serg

sigh . . . speaking of TCP and UDP, I've exam tomorrow about this stuff

I think i might stay up and skip second lecture tomorrow

IanC

00:36

what will the exam cover?

Serg

TCP, UDP, basic formulas, probably some basic types of connections and their speed. We haven't covered anything fancy yet, so i hope it won't be that difficult.

and i need to write up lab report. Mmmm, totally gonna stay up

IanC

by the way, some programs that were not so connection-based (like programs that were supposed to request a single file from a server and download it) usually used UDP, with the reliability of the data exchange being controlled in the application layer. T/TCP then came as a middle ground between TCP and UDP, to avoid programmers having to reinvent the wheel every time (and getting the reliability control back to the transport layer where it belongs)

being transaction-based lowered the overhead making it more efficient and faster than TCP

Nathan Osman

Hello from a kayak.

IanC

maybe I got too excited talking about this, been reading about this stuff for a while, guess I was waiting for the opportunity to talk about it haha

edwinksl

@NathanOsman careful not to drop your phone in the river

IanC

00:40

nice @NathanOsman! fishing? :)

Nathan Osman

I've got it in a zip-loc.

edwinksl

do people fish from a kayak???

Nathan Osman

No fishing.

Just a nice calm lake.

IanC

some do, there's a friend of mine from work that wants to buy a kayak for fishing @edwinksl

Serg

@edwinksl happened to my friend once. i bought her xiao mi m1 , but she rejected it, since she already planned getting a newer one

edwinksl

00:41

@IanC wow, okay, i have never heard nor seen it before

IanC

maybe it's not very common, I think I've never seem it either, but sounds cool

grab some beer, get some exercise and maybe fish some dinner :D

edwinksl

so little space on kayak and it isn't the most stable thing in water. hard to imagine people want to fish in it except for YOLO folks :p

IanC

the fishing kayaks are probably a bit more stable

Terrance

Darn, just got done answering someone, and then the question got deleted. :(

edwinksl

@IanC heh looks awesome

Zacharee1

00:47

@Terrance lolz

@Terrance link?

Terrance

It's gone.

Zacharee1

@Seth "what"

Terrance

It was about command line key generating

gpg

Zacharee1

@Terrance I have 10.8k rep though

mod powers :p

Terrance

True that

I think it was deleted by OP

Zacharee1

00:48

I can still see it :p

Terrance

Still almost 2.5K left for me to go.

Zacharee1

hurry up then

;)

Seth

@Zacharee1 -.-

Zacharee1

lol

Terrance

WOrking on it

Zacharee1

00:51

christ askubuntu.com/review/close/624039

Terrance

I think I have maybe earned close to 300 rep over the last 3 days.

edwinksl

@Zacharee1 that misspelling in OP's username is triggering me

Zacharee1

YEAH

oop

ugh, why can't we see answers for CVed questions in the queue

Terrance

I lied. Only 205 Rep over the last 3 days. :(

Zacharee1

:(

Terrance

00:58

That is OK. I have been working so much lately, I haven't had a lot of time to really sit down and answer questions.

Zacharee1

CVs done for today

Serg

TBH, i sometimes regret choosing engineering as my major

Dealing with all the fourier and laplace bs is tiring

Zacharee1

@Serg should've done tech tsk

Serg

@Zacharee1 it's just that the seeds were planted too late. I've never been doing tech stuff until i got to college

Zacharee1

tsk tsk tsk tsk tsk

:p

Serg

01:04

i guess, my kids will have it better off - they'll learn Linux and programming from early age

Zacharee1

@Serg well think of it this way. You have a natural skill in computers. Engineering will only make you more appealing to potential hirers

Serg

Sysadmin with engineering degree ? Sounds over qualified XD

( which is a common reason for candidate rejection )

But yeah, it's definitelly more appealing

Zacharee1

and you also have two very popular fields to apply to

Terrance

Experience is a huge part of it too! :)

Serg

That ^

Zacharee1

01:06

@Terrance Too bad he'll need 40 years of it

Terrance

LOL

Serg

I've 31k rep on AU over 2 years of my presense on AU, so that's gotta trim off a 0.05 years form that requirement, eh ?

Terrance

The team of guys I work with in the data center, that is one of the biggest questions we ask is experience with Linux. Extremely helpful when it comes to troubleshooting servers that have dropped out of the cloud environment.

Of course knowing the server hardware helps too.

IanC

edwinksl

@IanC compelling reason

Terrance

01:10

Sounds about right.

IanC

and more honest than 90% of the answers :p

Terrance

@Seth Apparently the chameleon in that video is the chameleon from SUSE. Here's another video by them: youtube.com/watch?v=_9aLiv5M6AQ

IanC

if I was to leave my current job, I'd consider working on the info tech area (I know, I'm being too broad, would still have to find what specific area really appeals me) but my degree has nothing to do with it

Serg

i am starting to think i just gotta give short and not very descriptive answers, because that's exactly the type of questions they ask

Seth

@Terrance yep!

Serg

01:14

"Why are you interested in this internship ?" Uh, honestly ? Because I need experience, and ain't no other place is willing to give no experience

Terrance

@Seth I think those guys are actually local boys to where I am from, just further south.

IanC

but for now I have stability working for the state, even if the paycheck isn't thaaat high. And I get time to keep my tech stuff as a hobby

plus I'd probably need some sort of degree to get in that area anyways

just curious, in which area do you guys work?

Terrance

Sometimes stability is the way to go. After I got laid off, I did consulting but then ended up back in a normal job for stability. I needed something to keep me going.

@IanC I am a data center build technician.

IanC

Nice! Even though my work is mostly manual labour, I like the environment, it's not stressing at all, having time to myself and my hobbies, not bringing work problems home and the stability, specially since economy is in a difficult moment right now in my country

I work mooring boats at the docks

Another thing that is cool is I can study when there is nothing to do on work, so I bring some programming/networks/linux books on my cellphone and read them when I have nothing to do on the job :)

Terrance

That's a good thing to do. Hands on when you can do it is the best thing to do.

Just like this systemd bug they are talking about. Unfortunately, I cannot seem to get my system to crash with it at all. :(

IanC

01:29

I've seem Nathan's message, but I didn't know there was a bug behind the statement

what is it about?

chaskes

@NathanOsman btw, have you seen this site: devuan.org

Serg

@IanC you mean the systemd bug ?

IanC

yeah

Terrance

Yes

Serg

@IanC techworm.net/2016/10/can-crash-linux-systemd-single-tweet.html

Read that article

Terrance

01:31

I am running the while true loop on the bug, and my system isn't doing anything. I can still stop and start my daemons. I can do everything on the system still. I don't get it.

Serg

basically , if you send null notification onver systemd, it crashes

nice vector for DOS attacks

Terrance

I am going to try a clean reboot. Just testing if this bug is affecting my 16.04 system

Serg

@Terrance if you haven't updated in last 4 days, it probably does. It's not version specific though it seems, people on github reproduce it with couple different systemd versions on debian

IanC

NOTIFY_SOCKET=/run/systemd/notify systemd-notify ""

Is that the bad guy?

Terrance

I have updated

Yep, no crash on my system at all.

@IanC I believe so.

Serg

01:34

yessir

Nathan Osman

I'm back now.

Serg

Exactly the same thing as on github github.com/systemd/systemd/issues/4234

IanC

NOTIFY_SOCKET is not defined on a regular shell, is it read by systemd as the destination of some notification?

Nathan Osman

Man, that was fun.

Terrance

OK, time to go feed my dogs and give the one her shots. Enjoy all!

IanC

01:37

see you later @Terrance!

on the comments it seems the bug isn't affecting everyone though

how can I connect to a ssh server and share files

IanC

scp and sftp

TheXed

like on windows i would use a program called winscp

IanC

use scp, the usage is very similar to the ssh client (since it is a client actually, but with the aim to transfer files only)

TheXed

02:14

how do I use scp?

IanC

I haven't used it yet, but if you know how to use the ssh terminal client you should get it real quickly, let me get an example

TheXed

Oh that looks like a lot of work...

I will just remote into windows :-P

or better yet...

IanC

say you want to copy the file /home/user/myfile from the remote server with IP 123.123.123.123 to your local folder /home/localuser

TheXed

vnc viewer,,,

IanC

would be something like:

scp [email protected]:/home/user/myfile /home/localuser

if I'm not mistaken

as I said, I haven't used it myself yet, but seems simple on the man pages, give it a look!

Serg

@IanC Fourier series and Fourier transform :)

Just trying to catch up on my digital and analog communication stuff

IanC

I had this on college, would have to study it again if I needed it though

I remember more about Laplace transforms then Fouriers

Serg

I think i killed my brain when i was taking Circuit Analysis with Laplace. I don't understand how i passed that class with B mark

IanC

had to use it a lot on a class called Chemical Process Control

you make EE right?

Serg

Yup

IanC

03:39

I think transforms are a bit heavier on your course, because it uses it a lot right?

Serg

Yes. And quite honestly, it hasn't been approached well enough in my program. Basic circuit analysis classes are just algebra, then you get to that Laplace class, and all of a sudden boom !!! Hello Calculus !!!

And partial fractions

I've talked with one guy about this. We agreed that students basically try to figure out math and at the same time figure out how does it apply to circuit analysis, which is wrong

It'd be nicer if there was slower pace

IanC

I agree

it only stimulates getting enough grade to pass an exam, instead of making an incentive for you to go after information and really learn stuff

which is actually a broad issue on the educational system, it's one of the reasons I wonder if it would be worth to make some graduation (or course) in the info tech area

Serg

03:54

That's exactly what I want. I wanna really learn this stuff, I want to really appreciate the genius of Laplace and Fourier and other methods to analysis. But in the end, it all just comes down to 1 or 2 hours of bull and spooking students about bad grade. That's totally wrong

I want to love that knowledge, I want to be obsessed with it, spend hours upon hours researching that stuff and doing something with it. It's just not happenng that way.

IanC

If only we could have the passion and freedom we have to study our hobbies, along with the information access and guidance we have (or are supposed to have) in college, that would be a good mix

educational system does not work the way it was supposed to IMHO, but I'm not sure exactly how I'd do it differently
