Ask Ubuntu General Room

Help appreciated askubuntu.com/q/793538/530811

Say, @grooveplex, what is "browser"? I'm assuming that's not Chromium?

@anonymous2 that is the native browser of Ubuntu

1:22 PM

@Rinzwind What happened to this user? askubuntu.com/users/58612/izx?tab=profile

He was last seen in 2012.

@AndroidDev maybe he simply lost interes or has other real life things going on preventing him from returning

@Rinzwind Ok, the Ubuntu browser. Just asking to be sure, because I have used some distros where Chromium was simply called "Browser." Come to think of it, though, it usually has the Chromium icon all the same.

@Videonauth But look at how much rep he has!

He's gained all of that since he left.

(Almost)

Yeah, he should at least come back and award a bunch of +500 bounties.

yeah his answers and questions are around for a while, and people reading and upvoting

I have some days to where i gain reputation without answering a single question and I only be here since 99 days

1:32 PM

@Videonauth here is my attempt gist.github.com/edwinksl/77be1e4d6594a0b2071cd3b0d903d2f3

@anonymous2 To whom?

@edwinksl looks not bad, so far but math is really unneeded in that case

char_limit = (char_num // len(charset)) + 1

@Videonauth your char_limit = (char_num // len(charset))+1 bugs out when if char_num is a multiple of char_limit

nope

it runs on my side really

@AndroidDev Well, me, of course, since I suggested it. ;)

1:36 PM

say charset is 'ab' and char_num = 8

you really just need char_limit = 4

not 5

well it defaults to 1

And since I need it more than the rest of you... (Don't think about that too long)

mhmmmm sec let me make a test case

I guess that would mean I also merit it less... :0

if you insist on not using math, then you can do char_num // len(char_set) + (char_num % len(char_set) > 0).

which may be less readable than simply using math.ceil

1:39 PM

well the remainder is always a float but im expecting integers

this is why i did the +1

simply

there is nothing wrong with setting a char_limit higher than what is required

but i don't like it, hence math.ceil

@anonymous2 You're gaining it pretty fast. Not as fast as @videonauth though :)

(Neither am I, for that matter)

lets say i have a limit of 1 and a num of 150 it would be 150 / 95 which is 1,578.. without the remainder 1 + 1 = 2 the same as math ceil would do

and you can apply that to any case

what if num is 190

it is 2 and not bigger than

if char_num > len(charset) * char_limit:
    char_limit = (char_num // len(charset)) + 1

ah o.k there is the flaw

ok then the limit would get to three

1:44 PM

exactly

mhmmm

that's why i said your char_limit is 1 larger than what is needed if char_num is a multiple of len(char_set)

well that happens if you transer c++ code :) ok have think this over and extend anyways because i want to add a gui and some more functionality

and still keeping it in a way so you can import it into other scripts

yeah your right math ceil is more elegant in that case

classic question btw stackoverflow.com/questions/2356501/…

there is even an answer that uses numpy, which is truly an overkill here

thats for sure

so int(math.ceil(......

or is it not of importance in python? in c++ i would get a type mismatch

1:52 PM

I keep wondering about how a lucky person Raja is. Their early (2013) questions get upvoted like crazy but show no sense of any research

math.ceil returns an integer

i just came across this function, but this doesnt work on non decimal numbers, if i type something like math.ceil(363) , it returns 363.0. Anyone care to elaborate — letsc Feb 14 '15 at 21:19

Why is that?

type(math.ceil(363))
<class 'int'>

Why are their questions perceived as being GREAT?

Yes, I'm a little jealous.

1:53 PM

mhmm ok than this has changed since this comment was done

If I would ask such a question now, I'd be burned to the ground — and rightly so

@Videonauth yeah looks like it

Q: How do I shut down or reboot from a terminal?

Their early questions are one liners (really, check for yourself) and I think they could easily be Googled in 2013

Even in 2013

393

How can I shut down or reboot Ubuntu using terminal commands?

@Videonauth also note the * operator, that operator is pretty cool

@grooveplex yeah but they have been quesions and answered andsince then people who google recieve often SO as result and so those questions get a big audience since then

1:57 PM

But were one line questions acceptable in 2013?

If they are clear, why not?

@grooveplex google.de/…

If I were to ask such a question today, I'd attract the same amount of negative votes

yep and a quick dupe close maybe too

which is the expected outcome

1:58 PM

because it already has been asked

But Raja couldn't Google?

Or use their imagination?

Or read man pages?

Lucky them :)

Just ran across this command: `:(){ :|:& }:`
P.S.: DON'T DO IT!! (Unless you want to destroy your computer)

well that graphic is kinda old already, i think even older zthan 2013 :) so youre right

@anonymous2 only thing which may happen is that you have to reboot because it becomes inresponsive

but no damage is done by that

It's the only command made up entirely of emotions :O

2:02 PM

it is a bash function

@AndroidDev he decided to leave AU

replace every : with a word and you migth see it better

@Videonauth Yeah, I just don't want to blow out my CPU or something.

You're right. That does make sense.

even my 2006 motherboard would shut down if the cpu overheats

It's a recursive function! :O

2:04 PM

@anonymous2 it fills your memory so quick and after that the computer is more busy with managing memory as computing, no real harm on cpus is possible

:)

and more recent computers might not even get stuck

because ubuntu has a limitation on recursions for functions build in

my old machine however gets beat to the point of no movement

Also I discovered a one liner that replicates yes

if you want to try it safely run it in a VM and limit the cpu usage to only half of your cores and 90%

echo y|tee /dev/stdin

so you only need to shutdown the vm

if i come across such commands i always be happy to blow up a VM ;)

installing does not take long

Q: install OpenSSL from source

ubuntu openssl

@Rinzwind Your guess, or he said that?

@terdon hahaha this is kinda nice :) --> ☃(){ ☃|☃& };

@AndroidDev a coupld of mods said that

Yeah :)

i wonder if there isnt a little bomb symbol as well :D

or a toaster symbol xD

well ok that may be windows specific :p

@terdon can you maybe remove the first two comments on this question askubuntu.com/q/793309/522934

2:30 PM

@Videonauth I deleted all of them, none of them was providing anything useful (except yours but that is obsolete with the rest gone).

yep

i dont mind mine gone would have delted it myself anyways then

@Videonauth I've removed the final snowman. Someone may blindly copy-paste this.

yeah ok :))

@StefanoPalazzo you never live dangerously?

@Videonauth 💣

2:32 PM

which Ucode is this ?

@Rinzwind I could tell you stories...

I don't think (read: I don't realize) I live dangerously, but I break things all the time :)

Avast Antivirus for Windows wants me to reboot, let's procrastinate it until the next century!

xD

Why

Windows.

Just WHY

2:47 PM

Needs reboots for nearly every change...

This I hated the most on Windows, this "you are a dummy and must restart your computer NOW" mentality

and it keeps nagging forever even if youre in the middle of important work

Or in the next century, like Avast! :D

mhmmm is there an even stronger random python lib as this normal random? i mean one which implements mersenne-twister and such ? (yeah yeah i know that /rev/random provides a better entropy)

o.O?

Isn't random's randomness random enough?

in some cases im working on not predictable enough ;)

2:54 PM

not predictable enough?

Uhm...?

yeah pythons rng feeds of of /dev/urandom in my case i need a recurring result after xx cases of random

for making test cases for something

@Videonauth For your test cases, you want to use unittest.mock (and unittest.mock.patch)

@StefanoPalazzo great, thanks for the lead, rest i can google

@Videonauth So you want to seed the RNG with a predefined value so that you can reproduce always the same pseudo-random sequence?

@ByteCommander exactly

3:00 PM

here's a test case if you want to cheat, or don't click it if you don't :) paste.ubuntu.com/18240087

bookmarked it but want to raed into it myself first

@Videonauth docs.python.org/3.3/library/random.html#random.seed

No need for a different module, the default random has that built in.

Warning The pseudo-random generators of this module should not be used for security purposes. Use os.urandom() or SystemRandom if you require a cryptographically secure pseudo-random number generator.

yep thats fine :) both solutions will find its purpose (just can't tell here which)

@ByteCommander it's good practice not to do any I/O in unit tests (i.e. no files, sockets, or devices). It makes the tests slower and more unpredictable.

That's why you mock stuff.

but that's my opinion :)

3:13 PM

mhmm a bit more than 8 hours for my 8th gold badge :)

nice

yep im getting 100 days old on 0:00 UTC

7.3k rep in 100 days, impressive :D

is there a way to make PyCharm wordwrap the output in the python console? Or am I simply blind and not find it in the settings?

Don't have it running, but probably there's a button for it right in the left side of the console.

3:35 PM

nope according to help not on the window itself

don.joey

3:47 PM

hi guys, no offense to new mods (on the contrary: well done!), but how in the world did Jacob not get elected??

@don.joey he lend me some of his fan base so i wouldnt look to bad in the election xD

jokerdino

@don.joey yes

I have a launchcode bug to look into,
file:///home/jay/Desktop/dur.png

o/ jokerdino, how are you , you have been very quiet lately :)

jokerdino

Been focused on other things these days.

4:00 PM

@ByteCommander the button for using soft wrap is in the debug console and then affects the python console as well if clicked

Aha.

Good to know.

in gcc, typedef int bool; gives this: error: redeclaration of C++ built-in type ‘bool’ [-fpermissive] It compiled fine in gcc on Ubuntu 15.10, but not in Ubutnu 16.04.
both are GCC5+.

Anyone switch to 16.10 yet?

@Rinzwind only in a VM still runs on unity 7 tho

and haven't looked at it lately

@Rinzwind I just switched like 15 minutes ago

4:15 PM

Hello everyone :D Can anyone tell me How to make use of SSH and TELNET to send messages ?

@rohith define 'send messages'

to who?

maybe my friends

who are also using ubuntu

@rohith use the write command, or wall, or mail.

all via ssh

@j0h @Journeyman any study materials that you would suggest , to learn more about SSH or TELNET ? :)

$man ssh

4:21 PM

@rohith telnet and ssh are essentially tools for running command remotely

oh

if you're on the same system, wall. If you're on another one, they'd need a client.

you can write a script that logs you in, and messages after login

for example. I have a script that sends messages over the growl protocol to my windows box

@Journeyman I had to google-search what was growl protocol ... I'm a complete newbie and I have Zero knowledge :P

@j0h just read the man-page "man ssh"...so ssh allows me to have a remote session ?

4:33 PM

@rohith provding there is a server, and you have permissions for it yes. then you execute commands, write scripts, send pre-writen commands etc.

oh

hows your day so far? :)

It's a national holiday here, so it's good :)

OH HAPPY CANADA DAY

hehe and I'm getting over my flu slowly and finished a first small rudimentary python program today

6:47 PM

@edwinksl Thanks.

@Videonauth Not cool about the flu. But finishing a Python program - that's awesome.

yep and it werks even is able to crate 100k character passwords with a decent entropy :)

@Videonauth Procrastinate it until next century ;-)

Aw man.

The Wayback Machine doesn't have the page I need archived.

yep but i think next century starts when i go to bed

@Videonauth you are about to reach "a century of days" on AU

indeedy and got today already my 4th steward badge :)

and in a few hours another golden one :)

@Kupferdrache what post is this

RIP ALAN RICKMAN

Q: Just downloaded the latest version of Ubuntu. How do I actually install it?

-4

Just downloaded the latest version of Ubuntu, What do I do now? I see where it is downloaded in my downloaded folder, but how do I run this operating system? I am new to this...Ha! Thank you

14.04

I think, it is off topic, close vote seem ok, for me, but, I don't think it needs a downvote as well.

it doesn't show any research effort

because if it did, the OP would have found the dupe

7:34 PM

well some people pass by leaving their close votes sadly, but to be honest this question is so bad that it hurts already

AU is pretty forgiving

and i mean it is no rocket sience to put a dvd do a drive or plug an USB in ;)

plenty of the new questions i see on SO have negative votes

I made a basic answer anyway befor it got closed, not a fully fleshed out one, but a helpful one, at least I hope so.

yep or new answers dont get UV :) but well mine will in time i guess

@Kupferdrache you can still flesh it out tho if you feel it is lacking

7:37 PM

@Kupferdrache you can just delete your answer on the closed question and copy paste it into the dupetarget if you think your answer is different from the rest

here is what i do, i answer a question, let it be for an hour or so then revisit it

Not without more information.

in any case, -4 is damn rare in AU, it is reserved for truly awful things

Most times I don't think my answer give any real new stuff, so I let be.

I am not good at explaining most stuff i try to learn for my self.

You wanna know how i learned to use Linux after I migrated to it from windows this year February?

7:42 PM

That could be a reson, why my own questions aren't well visited either. Or they are too special, who knows?

Sure, it is ever a good idea to learn somthing new @Videonauth .

Firstly i installed ubuntu on my laptop, banged my head against a wall because of the wifi for a few weeks untill i found ask ubuntu, broke serveral installations in the process then to make it suitable for myself, but only reading here

then after i was settled i made a vm and tried to figure out commandline question answers

just answered them

trial and error till i had the sollution

and if i broke the VM i started over

then stumbled over questions where i felt, huh? well i had this problem too a few weeks back and answered them too

this is how i gained 7k+ rep within 100 days

O lot of efford, it's a pitty you have done this already, less question, I could try the same with.

Simply do a lot of new questions every day, and i keep others normaly finding the dupes, im more the answer first then look for dupe guy :)

4 accepted answers per day plus maybe 1 upvote are already 100 reputation

i aim normally for answering about 5-6 questions if i can

per day

yup, I am still on 50, but I try to do my best.

i have to admit sometimes its really a race against the clock to answer a question :) some people here are really quick finding solutions

SHAME on you @rinz

xD

7:55 PM

@Videonauth 215 rep today so I wont bother you today ;)

hahaha good to know lol

I am still on figuring out, What I wantesd to much here: unix.stackexchange.com/questions/286740/…

@Kupferdrache Other thing is, the more answers you have already provided the more rep you simply get coming in per day somehow by older answers of you where someone found it helpful and upvotes it

sometimes I hate the chat for that, you get only a preview, when you post nothing but a link

@rinz when will you beat oli

7:56 PM

@edwinksl never

I am 3.1k up this year. so lets assume I can extend that to 6.2 over the whole year

gap is 41k

so ... if I keep it up... in 8 years?

so never :-D

yeah i guess the jump up to about the top 100 users here is easy, then its getting slower and slower to gain positions

1st 50k are pretty easy.

@Rinzwind you made me laugh, waths your specialty?

well but still not earned in three months this far i got knowledge xD

The longer you stay and the sooner you start in a board the easier it gets, as far a i can see it from my view.

8:02 PM

good morning. 8 am here in askubuntu

@Kupferdrache it is. you can just start answering anything you see. pick up 2, 3, 4 upvotes per anwser. stop when at 200. and do the same the next day. you will get extra rep from the 1st day on the 2nd day.

the 2n 50k though... ppl will expect long and thorough answers from you.

@Videonauth yes you can.

Didn't find enough answers for that for me, I come at one anwser per day at best 2 if I am feeling really good including the anwsers to my own questions. So it still a long way.

it is 10 pm here

@Rinzwind yep but the mlongest answers didnt bring me the most reputation ;) the short ones have done that

@Kupferdrache when I started I answered 10 through 20 questions a day aiming for 200 rep a day.

IQRL DRIVERS NOT EQUAL

8:06 PM

mhmm what to do with this? askubuntu.com/review/low-quality-posts/586275

@Edity this aint askwindows :=)

@Videonauth no action required

might ask in root access @Rinzwind

my personal feeling is to skip it because i was already who rose the LQ flag on this

hey someone, find a question from me interesting enough to upvote it, I answered it my self meanwhile. may be my other one attractes some comments soon(tm).

but chmod 777 again is so bad that i want to recommend deletion without a comment

well i skipped it

8:09 PM

@Videonauth dupe it askubuntu.com/questions/261250/… :D

@Videonauth hmm not true for /tmp/ 1 thing though: it MUST have also sticky bit set

@Kupferdrache by the way weekends are the best time to gain first rep

the amount of questions incomming is mostly higher as during the week

especially beginner questions

rep, isn-t that important, as long as I can get at least comment to my questions and/or anwsers.

@Videonauth voted for delete on that answer

rep is important!

@Edity nope. rep is nothing :=D

8:14 PM

@Edity edity not really, but still a nice side effect :)

:]

double-pinged

the quality of the answers count or questions respective

a number on a internet page. That is rep :=D
more important is your attitude on AU chat, in AU comments and in answers.

Are the people who approve suggested edits sleeping?

im banned from approving for today :) have my 20 full

yesp

8:39 PM

dammit rinz you where again quicker than me. I took to long for my anwser.

Slowly I am thinking, you must hve a link list laying beside you quick, you find the dupes each time.

@Kupferdrache You better advise to edit the /etc/default/grub and /etc/grub.d/<files> instead, followed by an update grub.

--> askubuntu.com/questions/793723/ubuntu-startup-run-level

that would be the proper way of solving it

you might need to google a bit where to put those parameters there to makeit work

:) tip to improve your answer

You are right, did the quick and dirty way I am using for my LFS boot entry.

8 swodniw

another thing if you fear to gain minus votes for something while you edit it, delete it and undelete it later after you have edited it

But you don't want to delete too many answers either. You might just want to compose offline than post when finished.

8:47 PM

^what he says

my tip is only if you have already posted an answer

and @chaskes if you undelete your answer later on this should have no impact, or?

I don't know about that one. I need someone more SE aware to weigh in on that.

well where are the old school mods when they are needed ;)

maybe rinzi knows that ?

@Kupferdrache na. just using askubuntu as a search engine from the google search bar

@Videonauth or add a "work in progress" to the answer

it is basicly that same ;)

@Videonauth I updated the answer with your suggestion.

@NathanOsman this aint a rant. this is just common sense :=D

8:56 PM

@Kupferdrache and i edited it a buit to make it a tad better and woosh you have an accept :)

It sounded like a rant to me :D

@Kupferdrache "Work in progress" (as rinziwind says) is cool. but, that I thought that answer that I just commented on kind of stretched the work in progress concept close to its limits. Just a thought. :)

and an upvote, cool so 25 more reputation :)

@NathanOsman :D the thruth is never a rant :+

There's a healthy element of rant. I also hate it when some company abandons a project you shelled out a lot for in just a year or so.

8:57 PM

Nice, doesn't solve my own problem, but feels good
