If you want to know what non-registered users think of your posts

Seth

@kos lol, my top voted post has more anonymous votes xD

Huh, this answer has 98 anonymous downvotes.

user139252

Alright, @kos, if you want to do the light grid problem, I made the input file generator more friendly to the task.

user139252

Before, it created a file that was a pain to process in the way I taught you in the challenge file

user136984

@edwardtorvalds: Oh, did you fix your GNOME issue or do you still need my help? :)

kos

@Seth Some of my posts were really not appreciated. I think I also understand why, I should probably edit them.

@HeatherBrown Ok, I'll check it out after dinner.

- Ubuntu 12.04 LTS

Summary:

libpng could be made to crash or run programs as your login if it opened a
specially crafted file.

Software Description:
- libpng: PNG (Portable Network Graphics) file library

kos

@ParanoidPanda Whoa, thanks.

user139252

How can I see which libpng I have?

user139252

which libpng returns nothing.

user136984

If anyone wants to subscribe to security updates like the one above from Ubuntu I think you can do so here.

user136984

7:34 PM

@HeatherBrown: apt-cache policy libpng12-0

Seth

@HeatherBrown apt-cache policy libpng12-0.

libpng itself isn't a package.

Jacob Vlijm

@kos @Seth hilarious, the anonymous votes seem not to make much sense :)

Seth

@JacobVlijm ikr, really weird.

user139252

I'm good :D

Jacob Vlijm

I think many of these (down) votes are done out of frustration, when someone tries out without the assumed knowledge.

@Seth, @Heather Maybe we should add a difficulty degree ("don't try this at home") :)

Seth

7:39 PM

lol

What do people use for earbuds? The free pair that came with my zune those years ago are almost done for. (yes, I'm cheap :P)

user139252

@Seth I use the ones that came with my Note :P

user139252

I don't even have the Note anymore.

kos

@JacobVlijm Some of them I understand why, probably they came from Google looking for something else, didn't find what they expected to find (maybe because the question was not quite the same as the problem they have) and gave a negative feedback.

I think that's the case for my worst rated answer: bash: ./file: cannot execute binary file: Exec format error is a common problem for 32-bit user running 64-bit applications, but in a question I answered the problem was that OP wanted to run an executable compiled for ARM. Probably just 10% of the user had that problem because they were trying to run an ARM executable.

user139252

I don't have any anonymous votes D:

Jacob Vlijm

@kos exactly. It is interesting, but not so much a reason to do it differently.

@HeatherBrown not at all???

user139252

7:48 PM

Then again, I have very few answers

user139252

Oh wait

user139252

Used the wrong user ID

user139252

I used my "Network Profile" ID

Jacob Vlijm

@HeatherBrown AHA, that's a good trick as well :)

kos

Typo -> askubuntu.com/questions/717798/why-wont-this-binary-execute

user139252

7:58 PM

@Kos Bonus points if you get it to do this

Jacob Vlijm

@kos you nailed it :)

kos

@JacobVlijm Like a typo pro XD

@HeatherBrown Nice! The problem will be Python, but I'll try my best.

Seth

@RPiAwesomeness So I dried my hacktoberfest shirt on low, doesn't seem to have shrunk any.

kos

@Seth Could you hammer this real quick? It's a typo: askubuntu.com/questions/717798/why-wont-this-binary-execute

Seth

@kos hammered.

Q: What privilege should 30k users get?

The last time we lifted the level cap was in 2011. Last year, we added a unilateral close-as-duplicate power for gold tag badge holders, but no new reputation level. So we've been thinking about giving users more reasons to keep playing. (I've answered this question with some circumstantial evide...

SmokeDetector

[ SmokeDetector ] Offensive body detected: How to have 2 (or more) distros share common /home and /usr partitions? by Evan on askubuntu.com

user139252

@JacobVlijm or @Seth, Do you live in the US and have a Raspberry Pi that you wouldn't mind submitting for an experiment?

Seth

@HeatherBrown yes, no. I don't own a single pi and I've eaten all the pie :(

kos

Why querying SmokeDetector doesn't work in this room?

Jacob Vlijm

@HeatherBrown I live in far, far away (the Netherlands)...

user139252

8:27 PM

Darn. Other countries would work, but it would probably be slow...

user139252

I want to play around with Apache's virtual hosts, shellinabox daemons, and VPN connections

user139252

Basically, recreate my website's daemons on other Pis, connect them to my Pi through VPN, have Apache point a path to those daemons, and then allow users to pick from "hosts" to work on.

user139252

So, if you know that "bifrost" has 5 users logged in, and you wanted to do something that could take up a bit of CPU, and "jotunheim" didn't have anyone currently logged in, you could create a user on "jotunheim" and work from there

user139252

I need a magic switch!

user136984

8:50 PM

Anyone here use the Tox client Toxic‌? :)

kos

@ParanoidPanda I saw your question, if you want to check it out the Arch package comes with the man page: archlinux.org/packages/community/x86_64/toxic

user139252

@zacharee1 Do you have a pi?

Zacharee1

@HeatherBrown no

user139252

Darn.

user139252

Well, technically, this could work on any always-on system

Dangit Blender. Why aren't you rendering my circle mesh?

user136984

9:29 PM

@kos: Oh, well I'm probably moving to Arch soon so that will be good if they package them with manpages... :)

user136984

Anyway...

user136984

Goodnight! :)

Seth

@HeatherBrown you should really just get another.

A model B or B+ should be cheap enough these days, and still add quite an increase to processing power.

Zacharee1

9:49 PM

@HeatherBrown what?

Journeyman Geek

@HeatherBrown hm. Sounds like a job for HAproxy or something as a front end

and maybe having one pi do authentication for everything

user139252

10:04 PM

@JourneymanGeek Yeah, I've got it all worked out. I'll take down the Pi I have running as my doorbell and use it as an additional host

Seth

10:16 PM

@HeatherBrown I'm sure something like a pi zero could handle the doorbell too.

VishwaPrakash H V

Hello all

Can somebody suggest me good books about unix shell scripting??

Seth

there's no need to bold it >_<

VishwaPrakash H V

:)

I googled it , but thought it would be better If I ask here

Can I ask these kinda question in Unix & Linux ? or is there a better Stack Exchange Site for these kind of discussions ?

user139252

@VishwaPrakashHV You could try this one

Zacharee1

@VishwaPrakashHV the problem with that question is that it's kind of opinionated. Here or on U&L, you'd probably end up having your question closed.

Q: How many comment votes do we each get in a day?

Today I ran out of comment votes, I did not even know this could happen. This is not attached to my Q&A votes, I still have 10 of them left. So I can make sure I don't waste my votes, it was annoying not to be able to vote on an important comment, how many do I get?

support comments votes

user139252

@Seth my Pi Zero is the one operating my Keurig, since I didn't need it to be connected to the internet :P

user139252

The door bell isn't really needed, it was just a fun project.

user139252

I spend too much money on pointless things...

Fabby

@HeatherBrown Don't we all???

Cigarettes, booze, ...

@VishwaPrakashHV How about free?

user139252

10:39 PM

@Fabby I at least don't buy cigarettes :P

user139252

Shocker to everyone, though: I do smoke. (Don't tell @Serg).

user139252

I partake in the social form of smoking popular here in the states, but originating in the middle east, known as hookah.

user139252

But only sometimes, usually weekends.

RPi Awesomeness

Le gasp

Fabby

@HeatherBrown And what do you fill the Hookah with?

Apples? >:-)

@HeatherBrown Every tried apple tobacco?

or Salsa?

@ParanoidPanda I subscribed you...

Because you're a walking security risk! ;-)

user139252

@Fabby If you mean an apple-flavoured tobacco, yes. I prefer the mango flavour hookah tobacco my local lounge has. It's sweet, yet tangy.

Fabby

@HeatherBrown Mmmh, never tried that one... Can you get the tobacco brand "Salsa" in CA?

user139252

I haven't seen it in any of the shops

Fabby

10:47 PM

It is pure tobacco, but reminds me more of cigars then of cigarette tobacco...

I tried the pure stuff at a friend of mine who likes to mix it with aromatic herbs... :-)

user139252

I should have written this in C

Mateo

hey everyone, ordered a nexus 4 - flashing to ubuntu right now!

user139252

Then I could compile it, possibly run it faster...

Fabby

@HeatherBrown In this case "possibly" = "certainly"... Only Assembler is faster then C... ;-)

Well, and maybe Go (Haven't tried it out yet myself, but looked at a few bench marks, and that's why it's on the list!)

Mateo

hm, slimport adapter is still in the mail, stay tuned I'll try out some convergence stuff sometime

yep, bluetooth

you can pair mouse/keyborar - and it kicks it into desktop mode!

    calls_counter += 1
