12:02 AM

I was wondering why that was almost 1 hour alive

I don't know why this dude can't able to figure out his problem.

1

Q: Regex to club consecutive lines?

I have text file like this name1 age1 name2 age2 name3 age3 name4 age4 I want the data in this format name1:age1 name2:age2 name3:age3 name4:age4 Can anyone suggest me any regular expression to achieve such results? I am using eclipse regular expression which works the same way as notepad+...

4

Q: Regex to club together N consecutive line in shell?

Let say I have a text file in this format field1a field2a field3a field1b field2b field3b I want to club 3 (or in general case N) consecutive lines, how will I do it with sed or other command line utility in bash shell? expected output field1a:field2a:field3a field1b:field2b:field3b

text-processing

And also see the votes received on SO and UL.

12:22 AM

@slm have you done rpm packaging? unix.stackexchange.com/q/166328/41104

12:34 AM

oh man, I swapped caps and esc for quicker vimming and now I keep pressing the wrong one >_>

1:08 AM

@Seth IS A FEATURE!

@Braiam hahaha

2:01 AM

Does anyone know how to digitally sign pdf files using free software?

extra points for intergrating into into a LaTeX workflow.

the points in this case are metaphorical. i haven't asked a question. should i?

Hmm, this does not look encouraging.

Q: Open signed PDFs in Linux

We have some PDF files which are secured by a .pfx certificate. On Windows we can use Adobe Reader to read these PDF files (with previously imported certificate). I've googled for a long time but I can't find a PDF reader which can open this. NOTE: Just so it's clear. If I were to open a PDF fi...

pdf certificates x509

@FaheemMitha - sign with your signature or digitally sign?

yeah that Q has been sitting here, it cannot be done

I've searched in vain

wanting to A'er it

@slm What does "sign with your signature" mean? You mean like a watermark?

your John Hancock signature

the latter. an invisible electronic signature.

impossible w/ opensource

2:05 AM

not possible then? bummer.

I couldn't find a solution

@slm Ok. that sucks.

nope only with proprietary tools

@slm Yes, so I see. If you coudn't figure it out, it's probably very difficult or impossible.

I've spent ~1 solid week researching that sucker

2:06 AM

@slm Wow, really? Sheesh.

couldn't come up with a workable set of tools

Are there technical reasons this feature cannot be added? is the signing thing part of the spec? did you talk to any pdf viewer devs?

most of the tools fail open so if the signature is done in a relaxed mode, then you think the opensource tools can handle it but if you sign the file so that the tools reject if they cannot handle it, you'll see that they're all deficient

Can someone please tell if I have understood correctly?

Hmm, looks like you were looking at this quite recently.

@slm I see

2:08 AM

seems to be a feature that no one in O.S. wants

yeah cuz that A is wrong

@slm Oh. Strange.

I was trying to A'er it for weeks before that guy and couldn't come up with a method

@slm what A?

Oh, right, the answer to that question

The sole A'er there is wrong

@slm Right, Got it.

2:09 AM

food for through: downvotes doubled this year compared to last year

Annoying that it can't be done.

Yeah but we have 10k more UV to only 1K more DV

so as a whole they're going down

meh, just singing with a gpg archive @FaheemMitha

yeah I think @Braiam's right, gpg is a better way anyhow

When did this site open its doors?

2:11 AM

go live?

@Braiam elaborate, please.

@slm yes

@slm proportionally speaking, upvotes only got 25% boost while downvotes got 100%

@FaheemMitha how software sign their tar release?

look at how those were dispersed user wise and I'm sure there's a pattern there

That's how it usually goes. We're getting more random people as more people discover the site.

@Braiam Ok

@FaheemMitha ;)

2:13 AM

@Braiam - I'd bet you money there's a huge cluster of DV's to a very narrow swath of users

I can think of 5 users that probably got a big chunk of those, not to mention DV'ing Q's is free

we see it all the time with crappy Q's where they're DV'ed into oblivion

if you take those DV's out I'd be surprised it the trend was increasing

@slm ha! you are the most downvoted user, followed by Gilles and Stephane data.stackexchange.com/unix/query/232037/…

@Braiam among us three, that is: that query only considers users who've made more than 1500 posts

@Braiam - I know from watching my rep I get a fair amount of hate voting

I assumed Gilles got it too

cost of doing business

@Gilles yeah, was wondering why your friend wasn't on the list

he's the leader when I've looked in the past

2:21 AM

when lowering it to 100 you can see him data.stackexchange.com/unix/query/243417/…

data.stackexchange.com/unix/query/edit/243419

@Braiam 1/3 received downvotes, excluding deleted posts

that's w/ it at 10

^^^^ sites sorted by the proportion of downvotes (deleted posts are excluded)

this excludes deleted posts

either we don't downvote much or most of what we downvote ends up deleted

if we check the total mass of all users votes (minus community) vs votes that are recorded on posts we may be able to know which is

If you don't use available libraries, if you reinvent every wheel just because you can, I don't want to work with you. — Louis Wasserman 4 mins ago

2:36 AM

Most of our DV'ing is in piles.You generally see everyone DV'ing crap in a group.

@Gilles - you got a script that pulls that?

I like to star interesting DE queries

@slm shhh! I'm trying to break in his system and get the script for the API

@slm data.stackexchange.com/stackoverflow/query/195762/…

I might have posted the formatting script on some meta

I have 10 downvotes. I didn't think it was so many. Mostly on questions, I think. And 3 on one question.

can we review this? data.stackexchange.com/unix/query/169338/…

2:52 AM

what's this query?

most of the questions linked to this one which was deleted ended as scrub duplicates

they can be deleted through

@slm report script

@Gilles - thanks!

@Braiam done. I either voted to reopen or to delete each of them.

good, I spent all my delete votes just on the book's questions

3:01 AM

@Gilles - did you VtR this?

0

Q: How to change themes for GNOME3

I have installed live desktop. How can I change it's theme?

I'm finally caught up with voting. Now I have almost three weeks' worth of questions to answer

ha

@slm no, delete (no useful answers)

you can see that in the mod timeline. Very powerful stuff.

3:12 AM

and just to finish, lets delete this one unix.stackexchange.com/q/50608/41104

yeah I checked it for the rest

OK I've gone thru and reopened the ones you specified and deleted the rest. I also heavily edited the reopened ones and their A'ers so they're in much better shape now.

@Braiam nuked

anything else?

well, read this if you want... unix.stackexchange.com/q/13577/41104 through there is nothing novel in the A's

ARG!! SE SO SLOW!

anyone feels against creating the haproxy tag?

make it

last one done too

maybe we should create a library in GH about those topics

3:40 AM

?

books?

4:08 AM

@terdon I don't know why I keep looking for the link of that

I have a question but it would be too broad or opinionated in the main site.

Is there any scenario where SSH local forwarding would be more advantageous than using the SOCKS protocol for SSH?

@Ramesh an application that doesn't support SOCKS

(but there's tsocks)

1 hour later…

5:42 AM

@Gilles Ok, noted

1 hour later…

6:59 AM

@FaheemMitha I just got the chat transcript of Oct 26 (wonder why stack message took more than a week and more to alert me. To your question of FOSS tax planning using indian laws and taxation, I know none.

@FaheemMitha for financial accounting, KK/Krishnakant is doing gnukhata (gnukhata.org) which is FOSS. They just released version 1.0 about a week back . See flossexperiences.wordpress.com/2014/11/05/…

1 hour later…

8:26 AM

@shirish Thanks. I'll take a look.

@shirish Yes, it seemed unlikely.

Do yourself use tax software to calculate your taxes?

9:08 AM

Hi guys. Can anyone shed light on:

wget -c phab.jasom.org/orfiles/filelist

GnuTLS: An illegal TLS extension was received.
Unable to establish SSL connection

Server side misconfiguration?

This uses mongrel2

@FaheemMitha no, do it manually. There are IT forms which use Oracle Java forms to help fill you but at times fail and at times are buggy as well. It would be nice if there was a FOSS solution for this. I have written on this on my blog as well sometime back.

9:27 AM

@shirish You do it manually? Ok. So, you do it yourself? No tax accountant?

I see 'Tax Guru' and use the web more often than not to resolve any queries. I would probably need a Tax Accountant if someday I turn to make a foundation or something, but as of yet can make do without one :)

@shirish What is Tax Guru?

@FaheemMitha this is it in.com/tv/shows/cnbc-awaaz-110/tax-guru-9981.html

it's a weekly show.

@shirish Oh. Can you watch it online?

I think there are some youtube videos, but not all.

search for Subhash Lokhotia on youtube and other places. If there is a CNBC Awaaz site which streams or records the shows you might be able to watch it (but would probably require flash).

10:04 AM

@shirish Ok. Did you find this tv show helpful? Videos are usually not an efficient way to get information

This answer looks kinda broken

A: How do I get the unix find command to print out the file size with the file name?

find . -name '*.ear' -exec ls -lh {} \; just the h extra from jer.drab.org's reply. saves time converting to MB mentally ;)

Might work if you restrict to files, otherwise will print out everything in a directory

@FaheemMitha Yep, and in spite of that 20 upvotes. Can't you just edit that to get the error out?

@Anthon I'm not exactly a expert with find and friends.

I might add a different error. If you know what you are doing, go ahead.

There is another answer a bit below which has the same error.

10:21 AM

@FaheemMitha The -f type was mentioned in the other comment on that post as well. The original answerer clearly doesn't want to improve this incorrect answer and the OP is alive as well and doesn't seem to care.

@Anthon yes, the other comment brought up the same issue without actually saying the answer was "suboptimal".

On the other hand because of the -name "*.ear" it is unlikely that a directory will be matched

For the subset it should work, but it is not a general answer

^^^ subset of the example directory hierarchy

@Anthon I tried it , got reams of non-matching stuff, then realised the problem.

should we downvote?

That is not going to help future visitors much, maybe we should just create a new question with a directory structure where .ear matches a directory as well, then refer to this post and answer that it doesn't solve it.

Then provide the correct answer and get the other one closed as a (subset) duplicate.

:-)

Unfortunately closing something on SO is going to take years, unless they purge the VtC queue again, then it will take forever

How do I find files in a list ending in .tar?

less gitfiles.out | grep *.tar | less

does not work

@Anthon That seems overly complex.

10:30 AM

@FaheemMitha grep '.tar$' gitfiles.out

@Anthon Thanks

Regular expression if you don't use grep -F, so the $ is end of line.

@Anthon ok

@FaheemMitha I voted to close with as reason that it belongs on Unix & Linux SE. Once it gets here we can treat it for what it is ;-)

@Anthon Well, @terdon has superpowers, so he can use them for good, and expedite the process, perhaps

10:55 AM

@Anthon Nope, too old. Can't migrate posts after a certain time. 60 days I think. I submitted an edit to it with -type f at least.

11:13 AM

Man, sometimes I wish I could downvote twice:

-1

A: Count total no of functions in .h files

If you use datatype functionname(arg....) you can use : egrep "\(*\)*;" headerfile.h |egrep -v grep |wc -l

11:27 AM

@FaheemMitha It's helpful as you get some tips sometimes. You are right though, that it's not efficient as maybe having a C.A. Each way has its trade-offs in more than one way.

11:39 AM

@shirish Ok. I'd have thought for a business, a CA was worth it.

Of course, they can be expensive

@terdon This Mohsen chap gets constantly downvoted, yet he is still here, and has over 2000 rep, which means he can edit without supervision. I hope someone is keeping an eye out for his edits.

I gave way to the dark side and downvoted this...

@terdon i don't see your edit. How come?

12:04 PM

@FaheemMitha it works out for businesses but that too of certain scale and size. I have deliberately kept it small so I can goof off, travel and do workshops and such which is not possible if I am into business day in and out. Hence the need for C.A. is less there. I do know a couple who do assist me for advice but that's the extent of help I take from them.

@shirish Ok

@shirish ever done anything with Common Lisp?

Ok, off to yoga. Later, guys.

nope, not my cup of tea, sorry.

1 hour later…

1:19 PM

@shirish Just curious. CL is not big in India, I guess.

3 hours later…

3:50 PM

@terdon you can, just ask 8-)

@slm The unfortunate Mohsen is down to -3. That seems like enough to make the point. One of those downvotes is mine...

It's fitting that it's a wrong A on a bad Q.

meh, if I want to count the amount of functions (was it?) I would drop grep and use emacs

Stephane put in the example code too. How much more can you help here? If ppl cannot even help their own causes even a little let it be.

gdb would be better solution here, 2 ppl have told hte OP as much.

The XY is the real issue IMO

yeah, but for static analysis I would use my text editor builtin awesomesauce

3:57 PM

anyone using lubuntu here?

Why would the gnome-control-center look different on this release vs. vanilla buntu?

2

Q: GNOME System Monitor "System" tab

In an earlier version of GNOME System Monitor on lubuntu there was an addition tab, "System" which displayed some handy system information in a single location including Ubuntu version, Linux kernel version, amount of RAM and processor info. How is this available now? Since the info was there i...

something seems fishy here to me

@slm because it isn't gnome-control-center but unity-control-center

you can install gnome-control-center, I just did it last night

yeah, but he's not using it but the fork, granted I don't know why he can't use the "system" widget

the fork?

something seems fishy

> The control center used in Unity 7. It is based on GNOME Control Center 3.6.

launchpad.net/unity-control-center

4:03 PM

if it was something actually mildly interesting I'd be inclined to help more, but the info he seeks is in like 10 other places, adjust and move on.

the only other thing is for me to do is d/l lubuntu and then show that it's the same and then find out that he's looking at the wrong monitor or some crap

@slm or, you know, poke @terdon with a sharp stick so he boots his VM :P

I thought I was by whining about it in here 8-)

Man I hate days where I feel compelled to help...

going to d/l lubuntu

feels sorry for @slm

cool, answered two questions today! totally in the roll

2?

now 3

my average is around .25 A's per day

4:16 PM

ah

1 hour later…

5:33 PM

@FaheemMitha @FaheemMitha just possible, python, ruby and bootstrap.js are all the rage nowadays because the first two make enough of a noise every year with their shows, while bootstrap.js for obvious responsive UI's and web at low-cost. I haven't heard much about CL in the Indian context, no.

5:48 PM

@shirish I've never heard of bootstrap.js. I do use Python.

6:20 PM

@FaheemMitha @FaheemMitha see getbootstrap.com

4 hours later…

10:45 PM

Anyone here know how I can tell what is included (i.e. packages) in a default debian install and/or on a liveCD?

11:20 PM

9

A: What packages are installed by default in Debian? Is there a term for that set? Why some of those packages are `automatically installed` and some not?

The base system is described in Debian policy as all packages with required or important priority You can search for the packages these translate to with aptitude aptitude search ~prequired -F"%p" aptitude search ~pimportant -F"%p" debootstrap installs these, tasksel will then install whatev...

finally, found 600 questions worth of my vote

also @Seth debian.org/doc/debian-policy/ch-binary.html#s3.7

@shirish Ok, I see.

@Seth If you mount it, I think there is a list of packages in there, like any archive.

Though it has been a while

11:35 PM

also @Seth ftp.debian.org/debian/dists/squeeze/main/installer-amd64/…

remember that Debian installation CD doesn't use deb's but udebs

@Braiam aha! That was more what I was looking for.

hm, no qt libraries?

why would they?

the same reason ubuntu has them?

err... Debian only includes the minimal stuff

so I see.

11:41 PM

Debian is akin to the netiso of Ubuntu, just the minimal necessary to install your system as you like

maybe you are looking for the live images instead cdimage.debian.org/debian-cd/current-live/amd64/iso-hybrid (check the .contents file)

well thanks for the help. Perhaps this means I'm looking at it the wrong way..

the log may contain some useful information too

thanks
