Twice today now...Anyone else having issues?

Zanna

this question seems a useful one for our site

I don't think it needs to be closed

It's really about setting up to write code, isn't it... that's on topic here

@Zanna reopened

@Fabby thanks a lot!

@Zanna people tend to forget AU is a "site for Ubuntu users and developers" <-en.wikipedia.org/wiki/Ask_Ubuntu

Zanna

8:12 AM

oh no...

that "developers" bit though is about development of Ubuntu specifically

we interpret this as an end user question

shell scripting is on topic... but pure programming questions in other languages are off-topic

haha it's a bit complicated

Q: Please don't close questions that are for "developers"

I see questions on Ask Ubuntu set to on-hold or being closed because they involved bugs and are meant for "developers". Stated in the description for askubuntu.com Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's built and run by you as part of the Stack Exchang...

discussion close-reasons bug-reports

wait that's a completely irrelevant meta post about something else entirely :D

sorry for that XD

the is this programming question off topic? is a pretty fuzzy area of our scope

I tend to go by the chances of getting a good answer in this area rather than any other consideration

like, I remember Eliah Kagan found a badly answered C++ question. He said, this shows that AU is not a good place for C++ questions. If our community can't evaluate answers properly, then it's not the right topic for our site

OTOH questions about Python for instance tend to get well answered here. So I'd vote to keep open or reopen if an answer's been posted

but this is a very tricky way to manage scope.

Jacob Vlijm

@Zanna thye site itself seems to be kind of inconsequent though when it comes to languages. Many, no practically all, cli questions are not Ubuntu specific, while a language like Vala is the "house" language of Gnome, so OT by definition one would say. Curious what would happen if I posted a Vala Q.

Zanna

I think Ubuntu specificity has nothing to do with it - simply that shells are used by so many Linux users

@JacobVlijm Your question would be on topic if and only if it were about developing something that would be part of Ubuntu. That's how I understand it

Jacob Vlijm

8:29 AM

Sure! but that should count for anything if you apply the rule strictly. I remember quite a few downvotes/close votes on programming for Ubuntu.

... as well as cli questions, not closed, despite the fact that they are not Ubuntu specific (which is fine with me, but still). Think the line between programming an scripting is extremely vague.

Many things seem to be more by tradition (which changes over time) than a rule that makes sense in all possible ways. Also note for example that we often see heavily upvoted answers on SO, containing only ... a link! @Zanna

Interesting to note the differences in perception.

@JacobVlijm Using a language in Ubuntu makes it on topic

Though I would assume there is a boundary where it would be better to ask it on a coding specific site :)

Jacob Vlijm

9:43 AM

@Rinzwind Thought it was the other way around: if a question is about an issue that needs solving -> fine, if it is about an issue + specific language -> programming question.

dessert

@Zanna @JacobVlijm Btw, where does this “Ubuntu specific” come from? I can’t find it neither on any help page nor in a relevant meta discussion, on-topic on the contrary speaks of “Ubuntu-related questions”. IMO the question whether something is specific to Ubuntu – what ever that means, a clear definition seems insanely complicated – should not be relevant.

Jacob Vlijm

@dessert I assume Ubuntu specific and Ubuntu-related is kind of the same?

dessert

not at all! one includes anything with Ubuntu, the other excludes anything that’s not.

terdon

@dessert There is no rule about "Ubuntu-specific", only about "applicable to Ubuntu".

Jacob Vlijm

9:55 AM

^ that's a nice definition

terdon

After all, there is almost nothing that is actually Ubuntu-specific. We would have a very empty site if we only allowed Ubuntu-specific stuff.

2

Jacob Vlijm

@dessert Yeah, I see, you' re right.

terdon

The development thing is indeed trickier. The way I see it, there are two broad categories. Classic scripting languages like perl, python, awk and the shell are traditional *nix tools and part of a sysadmin's toolbox. So questions about using those on an Ubuntu system are on topic. Compiled languages would also be on topic but only when the problem is related to Ubuntu.

Things like "How can I convert a string to an array in C" I would consider off topic, but "How can I query the procfs filesystem in C" would possibly be on topic.

I think Gilles's answer to this U&L meta post is also broadly applicable to us:

A: Unix C API calls ontopic?

Unix's shell interfaces tend to be pretty close to the syscall interfaces. In particular shell utility errors are often straight lifts of system call errors. So people who understand the one often can help with the other. Therefore I think questions about the system interfaces (i.e. the C API) sh...

Obviously not the general UNIX stuff, but the basic idea that if it is about the Linux kernel side of things (and, for us, is being tested/run on an Ubuntu system), then I guess it would be on topic.

So if you're developing an Ubuntu driver for a piece of hardware, for example, you should be able to ask here.

Jacob Vlijm

10:27 AM

@terdon indeed a tricky set of variables to decide on. In general, in cases of doubt, I feel there is more harm in a too strict policy than every now and then letting a case on the edge slip through.

terdon

@JacobVlijm Yesh! Absolutely.

I also feel it is always better to err on the side of allowing more content on the site than removing it.

This is a perfect example for me:

docker software-uninstall r

The question of managing a docker instance and the software installed on it is 100% applicable to and interesting for users of Ubuntu. And we just lost that question because of the too-strict policy. In an ideal world, I'd have just edited that to not mention Debian and then we would have gotten a useful question and the OP a helpful answer.

But, as it is, I just migrated to U&L instead.

@DKBose the quality definitely varies hahaha

I love the fermented foods and coconut based chutneys. Too yummy

DK Bose

IIRC, idli and dosa do involve some fermentation of the rice batter. But our hostel staff economically used to under-fry the dosa and under-steam the idli :(

@Zanna Please help me with that, a question’s title is “Is there a way to make it so the cursor is included when I prtscr key?” and I want to make it “How to include the cursor in the screenshots created by pressing PrtScr?” – is that acceptable or can it be further simplified or improved?

maybe “… screenshots created when PrtScr is pressed”?

DK Bose

@dessert instead of cursor, you could use "mouse pointer"? man gnome-screenshot refers to "pointer".

dessert

oh, didn’t think of that, thanks :)

Zanna

@dessert sure, but instead of "how to" I would put "how can I". Just because I'm pedantic

DK Bose

That reminds of my school teacher with "yes, you can but you may not" ;)

I'd go with "How do I" ...?

Android Dev

@Seth hi :) I've just been super busy...... also I probably should change my name lol, I love doing Android development as a hobby but I'm not super great at it....

@ByteCommander sorry to bother you again... The edit to this question has rendered my answer to longer "answer the question" if you will. Should I just leave it or?

(The question was changed from "Why is hibernation so complicated" to "How can I make it work on my laptop")

Byte Commander

Hmm, this is difficult

The original "why is it difficult" was something I thought to be a relatively bad question, but your answer to that is quite good.

The changes that got made, including the OP's specific hardware and steps taken to enable it, are very substantial, so you're right the answers don't really fit any more

I'd personally probably lean towards reverting the edits and asking the OP to instead post a separate question about their specific case and how to get that second bullet point to work, leaving this one as theoretical question about the general difficulties of hibernation. It might be closed as too broad/opinionated then maybe, but I think it's better like that to preserve the answers and content.

hmmmmmmm....

@AndroidDev I wrote a comment, if the OP's fine with asking a new question about the specific hibernate on lid closing issue and reverting the original question, that's how we're gonna do it. I don't just want to force that on them though.

@jmath1983 I see you got two relatively good answers about the theoretical difficulties with hibernation, which I think address your original question quite well. However, due to the substantial changes to your question over time, making it basically only about hibernating when closing the lid instead, these answers do not fit any more. I think it would be best to revert your question to what it originally was about and you then ask a new question regarding the hibernate on lid closing issue. What do you think? — Byte Commander ♦ 1 min ago
