good evening

> I am the Ghost of Debian Package Versions Yet-to-Be. I have come to warn you that you should avoid breaking an API at all costs.

@NathanOsman :O are you a GNOME developer?

:P

what have you not been telling us? :P

Why else would the Ghost of Debian Package Versions Yet-to-Be be at your house tonight?

1:03 AM

Lol.

Nah, I'm dealing with this: github.com/nitroshare/qhttpengine/issues/24

1:24 AM

@RobotHumans Descent is back on gog for black friday. $9.99 for the entire series (D1, 2, and 3): gog.com/promo/20171121_black_friday_sale_descent_pack

I already spent enough on Steam for now.

Planet Coaster is every bit as awesome as people say it is, BTW.

Unfortunately, it's Windows-only :(

@NathanOsman If you're actually interested in it (Descent, most people aren't 'cause it's old) this might be your last chance to get it. I was shocked it was back on gog. The two companies that each own parts of the IP had a disagreement and broke off their selling arrangement.

I'm not even sure why or how it's back

All that to say I have no idea how long it'll be back.

@muru dupe doesn't fit. I did ask for no fork bombs and preserving filesystem. Two answers on linked duplicate are exactly that - rm -rf / and fork bomb. O.o

Nobody reads questions these days

Fork bombs aren't restricted to bash

You can make one trivially in any programming language that allows creation of new processes.

Sergiy Kolodyazhnyy

OK, makes sense. But still - I did ask for no fork bombs.

Nope, you said no bash, so no fork bombs

And I don't see why I shouldn't be able to answer with a fork bomb

Question seems pretty arbitrary

Sergiy Kolodyazhnyy

Because fork bombs can be stopped (askubuntu.com/a/23535/295286)

@SergiyKolodyazhnyy yet you say assume root.

what prevents me from undoing that?

Sergiy Kolodyazhnyy

4:15 AM

Nothing, really, if it's root.

Eh, whatever. Still not a duplicate, IMHO

@muru should I edit to rephrase that, btw ?

Up to you

As long as you're asking how to make Ubuntu freeze, crash, etc., I don't see a difference

Also, another possible solution:
https://bugs.launchpad.net/ubuntu/+bug/1683889

Sergiy Kolodyazhnyy

@muru upgrading to 17.10 ?

Bug report says 17.04, but still..

Sergiy Kolodyazhnyy

I see you've a sense of humor. I like that

4:32 AM

If I did, I'd have it migrated to SU and closed as a dupe of that Windows question (step 1: install Windows, step 2: follow steps in this post).

Or maybe just stop at step 1

Sergiy Kolodyazhnyy

/facepalm

@NathanOsman and a web browser please . . . and themes . . . and appindicators

4:50 AM

whoa Lekensteyn answered? Been a while since I've seen him around.

Sergiy Kolodyazhnyy

Of course. My questions always draw attention of some of the best people in the community. Right, @muru ?

woot woot :)

For what it's worth, it is useful to be able to spin up a Windows VM on AWS.

@NathanOsman sounds like masochism :P

:P

7:27 AM

Argh. Windows Server 2016 is every bit as annoying as Windows 10. :|

what you have expected? Its still Windows after all

you can hear the hatred i have for windows, can't you? :D

IMHO the last really good windows was Windows 7

Journeyman Geek

ehh

Internally, windows 10 is probably a lot better

UI, can't please everyone all the time. Unless its gnome. In which case you can annoy all the people all the time ;p

Hehehe well yes i want unity back too, but ok does not seem to happen unless a big group of people dedicate work into maintaining it

lol

I tend to run KDE or LXQT

im running a GUI only for convenience tbh (firefox/VLC/Steam/libreoffice) the rest i mainly do in terminal

the one thing I need a GUI for on my main linux box.... is something they ought to support in the webui

(qbitorrent dosen't do rss on webui yet)

but if they did, I wouldn't need X

7:47 AM

:)

do we close questions now as EOL if they where perfectly fine at the time they have been asked?

askubuntu.com/review/close/779654 <--

@Videonauth No we do not.

26

Q: Please don't flag old questions as EOL

This discussion recently popped up on Active Questions because of a new answer. Ever since then, there have been EOL flags in the Close Vote queue for questions that were not EOL when asked; there are some from 2015, 2012, 2011, etc. None of these flags should have been cast, but I believe that ...

yeah left a comment and VTLO

you could give my comment a vote up so it shows directly

8:11 AM

I've now done so. Arguably that question could be closed as being a bug report, though I'm not sure. Either way, EoL closure is incorrect for it. Btw, it's not actually that the question is off-topic now but was on-topic at the time it was asked. It's that it's on-topic even now--unless some other off-topic reason applies--because it is about a release that was non-EoL at the time it was asked.

yeah cant change my comment anymore now , i posted a link to a second one in rhe raiders channel

this makes 4 of em i have to VTLO today for exaact the same closure reason

I saw this and that -- what were the other two?

sec let me find them in history

@Videonauth Well it's not a big enough issue that you would have to change it. But you can change it, by removing the comment and posting a new one. The only upvote on the comment is mine, and I can just upvote the new one. It's totally up to you.

ok then sec

8:14 AM

It's really good enough though. So like I said, it's totally up to you.

done

on both

nah was only those two but i had to VTLO a lot today

you can see in the history

I don't see much difference between the old and new comments. But I've upvoted them.

i took yout the , even it is EOL now

What I mean is that, like the previous comments, your current comments suggest that those specific questions are currently off-topic but that we refrain from closing them as an exception to the general practice of closing off-topic questions. What is actually going on is that they are still on-topic (or at least not off-topic due to being about releases that are now EoL), because to be off-topic as EoL a question has to be about a release that was EoL at the time the question was posted.

We actually do close some questions that become off-topic over time as a consequence of changing consensus about the site's scope. These, however, never became off-topic as EoL. Your comments link to the meta question, and probably no one is going to read into them with the level of detail that I am right now, so like I said, it is completely unnecessary to change them. But the new comments are no better than the previous ones.

They are just as good, though, and the old comments were really okay, so these are too.

10:49 AM

Another old question answered – and I learned about some beautiful screen color temperature settings. :]

4

Q: Using terminal to have xflux at a certain temperature at all times

I'm trying to configure my xflux to have the screen's temperature at 3200 at all times, however it only seems to configure it for night time. Here's the command I put in: ./xflux -l 52.5, -g -1.886 -k 3200 This only configures it for night-time, is there any way to have this all the time?

command-line f.lux

@dessert you can add to install redshift-gtk too which as well offers a tray icon for redshift with the ability to switch it off if needed or even switch it of for a certain amount of time (i.e. 30 minute, 1 hour and 2 hours)

@Videonauth thanks, that's a good addition!

<-- long time redshift user :)

11:10 AM

Hi ... wth is redshift?

f.lux is similar to it too

it provides the shift to a different color temperature at night times so it has less blue and so on

@Fabby awesome it is!

jonls.dk/redshift

@dessert still, tricky to set up if you want to have proper temperatures and not just a red screen :p

How does it work? does it use the built-in camera?

Light sensor?

no you give it your location and it uses the internal clock of your system to determine night time

11:18 AM

:D :D :D

OK, not interested then... >:-)

hehehe , god i dislike it when a user asks a question gets an answer for it and then goes on and asks a different question on the site without even accepting the answer on his other question nor even upvote it lol

If they confirmed that the answer actually solved their problem, then I think it is reasonable to suggest they accept it, so long as you remove the comment afterwards. (You should still remove it after a short while even if they don't accept it, though, since such meta-comments are noise.)

@dessert Nice!

old one anod now it seems to have fixed it for him in the new one

@Videonauth Yup...

Yeah, faketime is often useful. :)

11:23 AM

@Videonauth What I do is tell them to roll back their edits, accept the original answer and then ask a new question because we won't charge them more for an additional question...

@EliahKagan That's exactly where I learned about it! :D

:)

@Videonauth Wait... I think I misunderstood you. Is that even a different question? Or is a duplicate of their first one?

@EliahKagan its different now he struggles to install mongodb

before he struggled with the repo because he had no key in his kearing

Oh. Right.

I'm glad I asked first before voting to close!

So did your answer actually solve the OP's original problem?

@EliahKagan think so at least his newest apt update does not show a gpg: error

11:26 AM

It's a "gimme ze codez" OP

yes seems so his newest is probably a dupe but im not yet sure which target

or its unclear since he only dumps a lot of code on it

@Fabby Are there actual requests for code, or do you mean that in an extended sense?

@Videonauth But not a dupe of their own first question, right, because the problem is different?

I wonder if they did something else than what you said to solve the first problem, and if whatever they did might be relevant to the new problem. I'll comment to ask them.

@EliahKagan Extended version.

I mean: no research whatsoever in the question.

@EliahKagan nope not a dupe of their first question

so "I don't want to learn CLI, gust give me the command"

11:31 AM

I mean, it's completely acceptable to ask how to do something on the command-line in Ubuntu. People should search first, but there is absolutely no requirement to become command-line gurus as a prerequisite to using Ubuntu. Ubuntu is supposed to be "Linux for human beings." Our expectations cannot reasonably be the same as all the expectations on a site like Stack Overflow.

4

@EliahKagan A star for that.

I haven't looked into this question specifically, but how many times I've been able to answer questions I knew nothing about by going to them googlez is amazing!

--> sad this does only SO topics mostly : idownvotedbecau.se

(and this one smells to high heaven of that; i'll have a look after working the review queues)

@Videonauth Looking more closely at their terminal output, I think they forced the repo to be added instead of properly adding the key for it. The messages in both questions are about not being able to authenticate that same repo. This is why I had originally though they were duplicates, and now I am thinking they might turn out to be duplicates after all.

Anyway, I've posted that comment I'd said I would post.

11:36 AM

This second questions seems he is trying to install mongo from a repository which does not support his version of ubuntu

But aren't both messages about not being able to authenticate http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.4 Release?

W: GPG error: ubuntu.bigbluebutton.org/xenial-200 bigbluebutton-xenial InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 37B5DD5EFAB46452

old one

no mongodb mentioned at all

and the new question is about mongodb

whihc might be a requisite to the first program but not sure

You are correct! Sorry, I have removed and replaced my comment with one I think is correct. I still suspect they are related but the messages are for different repositories.

if it would have been for that same issue on the same repo i would have already closevoted it as dupe but it isnt a dupe at all to that first question of him

Yeah.

@Videonauth I'm not sure that's sad. I don't know how well linking to that site actually works on Stack Overflow, and I don't want to criticize its use with inadequate familiarity, but on other sites where I'm more active than SO, I've seen it used very poorly even in cases where commenters clearly felt sure they were using it correctly.

For example, although that question on Unix & Linux was somewhat poorly asked and the OP didn't describe their research in sufficient detail, it was very clearly not a case of no effort.

One of the benefits of having to explain oneself is that one can address a question specifically rather than just issuing forth platitudes. Another benefit is that, by doing so, one can often figure out if one is actually correct during the process of writing the comment. (Although my own recent, now-replaced comment would arguably be a counterexample to that. :)

11:43 AM

@EliahKagan yep this is why i said it only really covers SO specific and even there it is misued often

@ParanoidPanda I'm sorry to hear that. May I ask whether English is your mother tongue?

user136984

@dessert: And I will lick all your ice scream away if you're not careful! >;P

3:57 PM

@ParanoidPanda It's just that it's not mine and I like to learn from what people write: You used “this writing” in a way I wouldn't have thought it would be correct.

user136984

@dessert: Yes, people do say that generally in more format text, "at the time of this writing", meaning that at the time of the writing of the text it was true, thus explaining to those who read it in a year or something once this may have changed.

user136984

:)

@ParanoidPanda I really like that you don't just let the matter rest. +1

user136984

You got me worried for a little bit then.

user136984

I would say "at the time of writing"

but I don't think it really matters

since it's English, and there are no rules

user136984

@TheWanderer: I don't know, maybe the way I write it is more traditional or something, I picked it up from newspapers.

@TheWanderer There are rules, just that they are made by the people and constantly change.

user136984

4:02 PM

I don't see it so much any more though.

blog.hubspot.com/marketing/how-internet-changes-language

@ParanoidPanda I would assume the main reason your post was closed was not because it was self-answered but because it isn't really on topic there. You weren't asking a security question, as such, you were asking a question about configuring a specific piece of software. Yes, the feature you want to configure is security related but your question wasn't about the security side of things, it was about the software usage side.

So it would have been fine on AU, SU, U&L or any other site that deals with configuring software, but borderline or flat out off topic on Security.

user136984

@terdon: Ok, I didn't realise that, then they should migrate it elsewhere then.

@ParanoidPanda Migration is awful. Remember that normal users can't migrate to arbitrary sites, only mods can. So all a regular user can do with an off topic question is close it.

user136984

@terdon: Ok, I'll flag it for migration. Which site do you think best fits?

4:15 PM

@ParanoidPanda Don't flag for migration. There's not really much point to it. Also, if it is migrated it will keep its original datestamp so it won't be shown immediately on the /questions page. Just repost (since it's already closed) or delete and repost (but not while there's an open meta discussion).

And I'd say SU is probably the best site for it.

user136984

@terdon: Ok, I guess I will see if anyone answers on Meta and then repost if they don't like it. Or repost if there's no activity there for a little while.

I left a little comment as well so that people don't think it's malicious or off-topic reposting as that's generally not allowed but fine in this case given it was more moved than duplicated across multiple sites. In fact it's not at all duplicated because I first deleted it from Information Security. :)

@ParanoidPanda I'd keep the permalink to what terdon said, just in case. ;)

@dessert: Yes, you're right, that question could get a Massive Assault there otherwise from people who don't completely understand the situation.

To make this question on-topic it's necessary to reword it to clearly fit this site's scope after reviewing the community guidelines first, see askubuntu.com/help/reopen-questions. — dessert 15 secs ago

@JacobVlijm If you really think this question fits the rules, wouldn't it be straightforward to rather edit the actual question and adjust it to what you think OP wants (which is not really clear, you have to admit) instead of adding a note to the reviewers to the question which you on top of that already added as a comment? I don't mean to offend you, but I think this is not the way AU works and should be used.

11:10 PM

Lol: github.com/qt/qtbase/blob/…

@dessert a temporary note is quite acceptable I believe and has been done before. The question is quite clear imo, only when skimmed, it may seem a java related question. I therefore removed the java tag. It got nevertheless put on hold, a clarifying note is therefore obviously needed.

ah fun, the question I just answered gets an up-vote my answer doesn't lol :P
