thats what water does if it not covers the full plane and theres no friction on the plane it collides with

make the surface uneven and add some slight wind?

and only when im satified i bake at full res
bake and render i mean

Q: Correct way to queue items for a worker goroutine?

Nathan OsmanI am writing an app that allows users to upload files and queue them for processing. My approach to this is to create a goroutine for processing uploaded files and to use a channel to signal that a new file is ready for processing. Basically, the processing goroutine does this: for { while ...

go race-condition channel
:|
Videonauth
Videonauth
01:49
why not simply put a variable as lock, so the next item only gets processed when the first one is done?
TheWanderer
TheWanderer
does Go have interfaces?
Nathan Osman
Nathan Osman
Locking is slower than using channels in Go.
@TheWanderer Yes.
TheWanderer
TheWanderer
can you use that?
Nathan Osman
Nathan Osman
Woot! I got a clever answer already.
@TheWanderer What do you mean by interfaces? I should have asked that first.
TheWanderer
TheWanderer
like Java interfaces: callbacks
Nathan Osman
Nathan Osman
01:57
Ah.
Not like Java, no.
In Go, an interface defines a set of methods that a type must implement.
TheWanderer
TheWanderer
so an abstract class
maybe you should just use Java :p
wait no
PHP! :D

No.
No. No. No.

Just gotta give the channel a capacity of 1.
TheWanderer
TheWanderer
no idea what that even means
Nathan Osman
Nathan Osman
02:02
Channels are used to communicate between goroutines.
(Which are like mini threads.)
So one goroutine sends on the channel and the other receives.
The only catch is that both operations block by default.
You really ought to learn Go :D

@Terrance Should it be undeleted? That can be done. I could cast an undelete vote, and since it has two of them, that should be sufficient. Would you then answer it, and in your answer would you be able to explain why enabling that repo would address that problem specifically?
Videonauth

@EliahKagan That was at least my assumption and thus gave my undelete vote (the second one)
Terrance
Terrance
03:20
@EliahKagan I believe so. After looking at the files that are saying that they will not be installed they seem to be coming from kubuntu-ppa/backports when I look at them in my apt-cache policy command.
Terrance

Honestly, it really is not a big deal if it gets undeleted. OP may not want to install the kubuntu-desktop anymore.

@Terrance Sorry, I was afk. If you still want to post an answer, and your answer would use the specific details of the question while also benefiting people besides the OP, then I think it's reasonable to undelete it. I'd definitely cast my undelete vote if that is the case. So you can let me know.
Eliah Kagan
Eliah Kagan
06:22
To clarify: if you think the question facilitates an answer that'll help others, I'll absolutely vote to undelete. If the OP doesn't want their name on it, they can have SE dissociate it from their account (then it'll show as being by a grayed out "anon" user). I'm not generally reluctant to undelete other users' posts. But if it's only to help them, not others, then I'm inclined to go by their choice to delete it. That isn't site policy or anything. But for me that's the deciding factor here.

@Zanna I just noticed that in that answer you mention:
> You can remove the quotes, unless your username has special characters, or you can...
But why would it be a problem for the username to contain characters of the sort that sometimes trigger expansions by the shell? Are more expansions applied to text expanded from ~?
My quick testing suggests this does not happen, but are there versions (in Ubuntu) where it occurs as a bug or something?
I have found this. But all versions of (including EoL releases) have had Bash 4, right?
Zanna
Zanna
I was just worrying about this... it would be bad if it did get expanded further
I shall remove those words...
Eliah Kagan
Eliah Kagan
Oh, actually some old releases have had older Bash versions.
old-releases.ubuntu.com/ubuntu/pool/main/b/bash
No currently supported release does, though. My 14.04 system has bash 4.3.11. Nobody should (even be able to?) have stuff in their username that would trigger problems. But people could have weird home directories. I'd suggest either removing the warning as it effectively doesn't apply to Ubuntu, or clarifying that it's the home directory, not just the username, to which the weirdness caveat applies (as if the current warning is needed, it doesn't do the full job of warning about the problem).

15:18
@dessert There's a huge difference between them. One just posts the homework assignment expecting us to do it fot them, while the other tries, shows what they have and only asks for help on a specific aspect they're having trouble with.
The first is off topic as simply "too broad". The second is fine and worth upvoting.

@terdon That's right, unfortunately the bad guy does it some days earlier every time. :(

@dessert So? Just downvote and vote to close.

Will gcc command/process (in gnome-terminal) continue running if I close the lid of laptop and screen-locks?
dessert

15:28
@terdon You're right, there it is – evil mod!
;)
I think so, but why don't you just try it with e.g.
for i in {1..20}; do echo $i; sleep 1; done
Videonauth
Videonauth
@Pandya if your laptop doesn't suspend when the lid is closed it should still run
Pandya
Pandya
@Videonauth yes, it doesn't suspend, it (clausing the lid) just cause for screen-off and lock
Videonauth
Videonauth
then it should stil run if you open it and unlock your screen, but if that compilation is important, try it with a shell script first, if that is still running you can be sure your gcc will be doing what he does still when you close the lid
terdon
terdon
If it doesn't suspend, then everything should continue to run, yes.
Pandya

@dessert oh! it looks stopped or slows down atleast! :(

@Pandya Really? That's unexpected. oO I do that all the time and it works flawlessly.
Do you say closing the laptop lid slows down sleep? That's actually quite funny!
Pandya
Pandya
@dessert Yes, I've just tried: typed the command, press enter and suddenly closed the lid for about 40 seconds and when I opened the lid and unlocked the screen, it reached to 10 only!
@dessert I think locking the screen may allow process to continue but I need to check what happens when I close the lid.
How do I check it?
dessert
dessert
@Pandya I have no clue.
terdon
terdon
@Pandya Why are you so sure it doesn't suspend? Also, try printing to a file and not the terminal: for i in {1..20}; do echo $i; sleep 1; done > file
Pandya

@terdon Yes, well I want to check it, is there any gsettings scheme I can check with, let me search...

Btw, if suppose I don't close the lid and screen automatically off and lock (with lid opened) then Can we surely say that process would be running? @terdon @dessert
terdon
terdon
If it's just the screen, then yes. Just like in a normal desktop: if you unplug your screen, nothing is affected.
dessert
dessert
@Pandya Not at all! You could run low on battery power, there could be a blackout, your hard drive could suddenly fail, your CPU could suffer a terrible meltdown, or your evil kitty could press Ctrl+C. There is no way to be absolutely sure your process will continue to run.
Pandya
Pandya
Let me pop-out my actual problem: I need to run a c programme for about 14 hours (for 200000 iterations). Now here I want two things. 1. Process shouldn't stop in any case (I'll going to put my lapttop plugged in) 2. It would not be a good idea to stay the screen on always since it may reduce the life of screen/battry. So, I hope that screen may off and lock but process should continue anyway. I am ready not to close the lid. @terdon @dessert
terdon
terdon
15:45
@Pandya Then just don't close the lid.
I would also run it in the background so you don't stop it by accident. But I've run processes that take weeks with absolutely no problem.

nowadays it's an 8-hour exercise.
@ByteCommanderthere are 3 basic DR tests:
1. comms fail-over test (needs customer NetEng and our NetEng)

2. DC fail-over: Shut down primary site, fail-over to secondary.
3. Bubble test.
now a bubble is a snapshot of the DR environment in the second DC completely firewalled off and brought up while production site keeps running.
That's all it is... Not rocket science.

aha, so the intention is not to accidentally break down prod while testing with that last one :D

Just a combination of storage, compute and network technology.
Yup: don't touch PRD

It is... But it's not if it's the first one, takes 2 weeks of scope definition, 4 weeks of execution and the customer wants it done all over again in 2 weeks time when none of the lessons learned have been implemented because their beancounters went for a drink and abandoned the test and I was awake for 30 hours to give them what they wanted...
"Hey, you're German, why don't you get the Germans to set everything up next week while we celebrate Thanksgiving?"
Forgetting that: There's like 2 of us in Germany (Sales organisation doesn't count: they're 30 or so)
and maybe 8 techs in the UK.
And I'm the only one working in both EMEA and AMER...

And on top of that, these are West-coast guys so they wake up when my day is finished...
I'm just pissed off is all.
And the Sales guys will probably kow-tow and give the re-test away for free.
