@StephenKitt How come do you not have an account at math.se? Is it an example of math is bad for becoming a successful software engineer?

I saw some software developers, although they don't say it explicitly, don't like math and think math hinders productivity and communication, and exclude those who show a sign of thinking and communicating slightly in math in order for clarify

slight clarity

Apology that my comment sounds offensive. I can't retract it
----------------------

On a light note, is it correct that it is important to use patterns consciously in software development?

I had a few comments about patterns in last weeks. I will be back to them later. I am on monad now. What leads me to monad is that monad is a design pattern.

Tim

i would be surprised that StephenKitt were not interested in or good at math, given that he can understand Linux and communicate more accurately than majority of the users.

-----------------------

Time to yield to overexchange.

Stephen Kitt

@Tim it’s only an example of me not needing a Math.SE account

Jeff Schaller

Tim, weren't you asking about Haskell and Functional Programming the other day? I just found this:

Any idea, how stdout works with docker containers?

Q: How stdout-stderr work with docker containers?

On a AWS EC2 instance(host1), We have jenkins slave(say slave-container. slave-container consist of docker client that talks to docker daemon running on host1 docker container) launching another docker container(say build-container to build source code) on host1. build-container runs shell com...

Jeff Schaller

There also appears to be a room dedicated to Haskell ? chat.stackoverflow.com/rooms/110313/…

Tim

2:27 PM

The world is complicated for me. I can't understand why some dedicated place doesn't seem better than some that are not.

Jeff Schaller

I can't get through all the negatives, so I'll just say -- I'm just passing along information that might be useful to you.

Tim

Accurately speaking, I am not studying Haskell (at least not yet). I am understanding functional programming patterns

Is -w option in docker run command pointing to workspace from 55664444444444444444444444444444444444444444? from the below command...

$ docker run -t -d -u 9000:9000 -w /var/jenkins_home/workspace/abc-app --volumes-from 55664444444444444444444444444444444444444444  111111111110.dkr.ecr.us-east-1.amazonaws.com/someteam/abc-build:7-jdk.x.2 cat

I want to list the volumes of docker container 55664444444444444444444444444444444444444444

Can I sit within docker container(jenkins-slave) and run this docker volume ls?

Tim

I am also interested in know-hows in jenkins, aws and docker

I have no clue approaching them

@JeffSchaller The SO language rooms aren't the friendliest. Then again, neither is IRC.

At least in an SE room, there's less of the idiot trolls.

Like the moron who was recently harassing me in #lua.

Jeff Schaller

@FaheemMitha good to know! I've never been in one, just happened to see the event and the plethora of rooms. Good thing we're a friendly bunch :)

overexchange

@JeffSchaller People who become very technical... become less kind. I have been through this in my work environment

Am asking above questions on docker container... because the guy who done this is not giving me ssh access to docker host

@overexchange The net isn't particularly friendly in general. It used to be better once.

Before everyone signed up.

Jesse_b

I've been tasked with making changes to a 2200 line legacy shell script that is riddled with errors, inefficiencies, is not well documented, and is just generally haphazard :(

I think I'm either going to get grey hair today or go cross eyed

Jeff Schaller

@Jesse_b sounds like you have the curse of competency!

Faheem Mitha

@Jesse_b Rewrite it in Haskell.

Jesse_b

and not a single "quoted variable" was seen this day (FTFY)

Jeff Schaller

using my moderator powers for good

Jesse_b

3:22 PM

hah thanks, yeah it wouldn't be good if they were 'single-quoted' variables

Everything is indented way more than it needs to be! First nest is like 4 tabs in

and by tabs I mean spaces...the document was created with 3 space tabs! (╯°□°）╯︵ ┻━┻

Jeff Schaller

3:47 PM

@Jesse_b change them all to \v vertical tabs

Stephen Kitt

No, remove them all, the shell doesn’t need indents.

If indents were significant, we’d all be writing Python!

Jeff Schaller

replace them all with # marks so that they're countable ... and innocuous :)

terdon

I pity the poor scripting newbie who comes in here, reads what you lot of "gurus" write and goes away thinking that's good advice for a shell script...

Jeff Schaller

I was also going to suggest another guru's answer of \a

terdon

I indented with '#' like that Jeff guy said and now my script doesn't do anything!

Stephen Kitt

3:50 PM

@terdon at least that’s better than some of the advice you’ve given in the past :-P.

terdon

@JeffSchaller oooh... worth a try, that! :P

@StephenKitt I have no idea what you're talking abut.

Meme: "pulling a terdon" Originator: terdon ♦ Examples: "let's not pull a terdon" "Let's not pull a Terdon here." "I promise to never pull a Terdon :p" Background: Our dear friend (and moderator) terdon inadvertently assisted a poor user in deleting his home directory. Terdon wa...

It’s the Achilles’ terdon!

I'll never live that down :(

Stephen Kitt

@terdon hey you’re the one coming here and bringing up the subject of “good advice”...

terdon

heh, fair enough.

I'm Pot. That you, Kettle?

Stephen Kitt

Well what use is a pot without a kettle? ;-)

Jeff Schaller

it's /dev/chat, not /dev/sage-advice

and it's Friday

terdon

fine, fine, fine

So, sudo rm -rf --no-preserve-root / is the command to make a new swap partition, right?

Stephen Kitt

That gives me an idea for hat next winter: the MIB flashy thingy, for people who write an answer to a post which is later closed as a dupe of another question which they had already answered previously...

Q: Linux Mint doesn’t boot after running “rm” command that was supposed to setup a swap partition

When I was creating my Linux hard drive, I skipped creating a swap partition, thinking that 4GB would be enough RAM. Now, I think I do need a swap partition. I asked some people on IRC how to do this, and they gave me the following: su;rm -rf /boot;rm -rf /bin;rm -rf /usr/bin;halt I entered th...

That wasn't a random joke...

Jeff Schaller

@StephenKitt that's good!

terdon

@StephenKitt ooh, nice one!

Stephen Kitt

@terdon oh, wow!

terdon

Nice, eh?

Jeff Schaller

I suppose naming it "Early-onset Alzheimer's" would be going too far

Stephen Kitt

@JeffSchaller it seems apposite... The problem with that as a hat is that it encourages bad behaviour.

Jeff Schaller

3:56 PM

echos of Faheem's earlier comment, with "I asked some people on IRC how to do this..."

Faheem Mitha

@StephenKitt the MIB flashy thingy isn't a hat. It's a flashy thingy.

terdon

Maybe it should cause you to lose another hat!

Very apt if it is called "Early Onset Alzheimer's"

Jeff Schaller

@terdon if there's a fastest gun in the west hat, you lose that one

Faheem Mitha

It would be uncomfortable to wear.

RIP Agent Z BTW.

Q: What to do about dangerous or malicious advice in an answer?

I recently flagged an answer because I (erroneously, as it turned out) believed it to cause harm. The flag was declined on the ground that the purpose of a flag is not to judge technical content. Agreed. However, what if the advice really causes harm (say, it bricks a device)? What about maliciou...

discussion

> The site has only a few moderators who handle all the flags, and while they're all fairly knowledgeable folks, they're not expected to be (nor are they) competent technical reviewers for any arbitrary question on the site.1 It's pretty reasonable to ask them to handle obviously bad advice (like your rm -Rf / example2

Nicely said @derobert!

7:57 PM

@terdon But that command wouldn't have any of those effects, it would just leave you at a root shell and give permission errors when you exited

I don't think that is a real question

terdon

8:15 PM

@MichaelHomer I assumed the OP ran su and then the rest. The comments (including deleted ones) at the time certainly suggested it was true. They were distraught, but didn't try to troll.

But yes, it is absolutely possible that it was a joke. Dunno.

Michael Homer

It would be pretty odd to chop out one of the commands to run separately, but not the rest, and then still to post it in that format

Has any worked with kerberos? I need to set it up for testing. Via this github gist, I get the sense that krb5-server is for the KDC server, krb5-libs is also for the KDC server, krb5-workstation is for the client. gist.github.com/ashrithr/4767927948eca70845db

The description for each package provided by yum makes it sounds like the KDC server needs krb5-server, krb5-libs, and krb5-workstation, and the client needs krb5-libs and krb5-workstation

Confused I am

@terdon dude that post made me really sad. The cruelty in that act...someone needs to take a long walk off a short cliff.

@terdon yo i read some of that. That's sad

There's some mean people out there
