Hello shka_.
7:02:52
shka_
hopefully beaches ubuntu stopped it's rebelion
7:03:16
no-defun-allowed
yeah, hopefully it's stopped with the GPU nonsense
7:03:35
shka_
not sure if it was gpu
7:03:50
no-defun-allowed
that's true but i have the same problem

hello heisig (IRC)

Hello shka_. Hello heisig.
8:18:55
beach
No, it is still crashing, and I can't use Ctl-Alt Fx when it does.
8:20:42
shka_
beach: what about the memory usage?
8:21:19
beach
I am not sure how to check that. I mean, I can't wait until it crashes to see, and I can't survey memory usage every minute of the day either.
8:21:28
beach
But I seriously doubt that memory is the problem.
8:22:05
shka_
heh, i know page that leaks memory in firefox
8:22:09
beach
My SBCL heap is 10GB, but I managed to do that on a machine with half this much memory.
8:22:14
shka_
32 gb will last you 5 minutes ;-)
8:22:42
shka_
anyway, we can automate checking memory
8:23:12

"eating 32gbs of ram" is a chrome thing
8:26:30
beach
I can not understand why an application leaking memory would make the computer grind to a sudden halt.
8:26:42
no-defun-allowed
beach (IRC): how many tabs do you use in firefox?
8:26:48
no-defun-allowed
well, swapping could be an issue
8:26:59
beach
I would think it would start by paging, getting slower, and then, when the application ran out of (virtual) memory, the system would kill it.
8:27:24
no-defun-allowed
i've had embarrasing pauses occur when i assume something is going way too hard on memory or processing time
8:27:30
beach
How can paging (swapping) make my computer grind to a sudden halt?
8:27:55
no-defun-allowed
well, i guess it's not going to kill your computer like that
8:28:09
beach
Yeah, I wouldn't think so.
8:28:11
no-defun-allowed
one sec, gonna write a program that leaks memory
8:28:43
beach
I may have up to 10 Firefix tabs sometimes.
8:29:17
beach
On my old system, I had way more, because it would run for months.

with riot.im, youtube and stackoverflow open my firefox is using 340 to 500mb, presumably i saw some major gcs
8:30:19
beach
What was the `top' command again?
8:30:59
no-defun-allowed
i use htop and watch the RES line
8:31:19
no-defun-allowed
htop uses a M suffix for MB, top uses KB with no prefix
8:32:07
beach
large number of threads though for firefox.
8:32:45
shka_
beach: could you please simply change enabled to true in /etc/default/sysstat ?
8:32:46
no-defun-allowed
same here, but afaik those are mostly sharing the same space
8:33:07
beach
shka_: What does it do?
8:33:43
shka_
it enables automatic, periodic system resources usage statistics gathering
8:33:45
beach
shka_: I don't have a file named that.
8:33:54
heisig
beach: I am sorry to hear that your computer is still giving you trouble. I would guess your problem is either hardware related, or a problem of the GPU driver. The other software components of a Linux system are usually quite stable.
8:34:10
heisig
I am pretty sure that browser tabs or memory requirements are not the issue.
8:34:33
beach
heisig: Yeah, me too.
8:34:49
beach
shka_: I am fairly convinced it is not about using resources.
8:34:49
shka_
it is basicly automatic and you wont have to remember about it
8:35:59
beach
Sometimes it even crashes 5 minutes after I reboot, and I have not had time to do anything then.
8:36:01
shka_
i wonder if this is a gnome issue, though
8:36:09
beach
Sometimes, with the same kind of usage, it can run for a week.
8:36:28
shka_
ok, that does not sound like resources usage
8:37:11
no-defun-allowed
okay, i got a pretty bad lockup from memory leaks but it wasn't permanent
8:37:11
beach
I suspected power spikes, but now I have a UPS too, so it wasn't that.
8:39:13
shka_
beach: well, that would not help with faulty power supply, but hardware is supposed to be fine

no-defun-allowed: Thanks!

mine gets killed at around 8300MiB. i have 8gb memory and 2gb swap with firefox, emacs and xfce4-terminal open.
8:41:17
beach
I need to try to get some real work done today. It is 10:40, and I haven't done anything (other than house chores and shopping for food).
8:41:35
no-defun-allowed
stuff gets very slow around 6500mb, X is laggy and my music starts to chop up
8:41:50
beach
Yeah, those are not at all my symptoms.
8:42:13
beach
It is very fast until it grinds to a sudden halt.
8:42:19
beach
Now slowdown whatsoever.
8:43:00

this is also distinct from what happens to me when my machine crashes.
8:43:30
no-defun-allowed
mine will freeze, audio will loop the last second or so and the screen will become garbage or blank out
8:45:53
beach
Ah, that's different from mine. Here, the screen looks fine, but I can do absolutely nothing.
8:46:00
no-defun-allowed
i wonder if i can bootstrap SICL on my machine with less memory
8:46:21
beach
You can try. I use a 10GB SBCL heap.
8:46:28
beach
But I probably don't need it all.
8:49:06
no-defun-allowed
i can't find concrete-syntax-tree or eclector on quicklisp
8:50:06
no-defun-allowed
they are on your github page so i'll use those
8:50:30
beach
Sure. I thought the were in Quicklisp.
8:51:22
no-defun-allowed
here we are, it's compilling nw
8:51:46
beach
I am working on the code, so I may have broken something.
8:51:59
beach
I try to check as often as possible, but...
8:52:05
no-defun-allowed
okay, it compiled with a 4gb heap, using around 700mb before a full gc
