i think you disable the firewall by using sudo service ufw stop (but don't quote me on that

zleap 2017-02-27 12:45:48
if ytou disable the firewall and it works you know the firewall was possibly causing the issue

I've been having a problem where my game repeatedly freezes for a second at a time, and I've noticed that each time this happens, my CPU0 usage drops to zero for a brief period... so maybe there is something wrong with CPU0, is t here any way to disable it? if I try echo 0 | sudo tee /sys/devices/system/cpu/cpu0/online I get permission denied (I can disable the other 7 CPUs)
causative 2017-02-27 13:01:27
or I'd like to switch some other CPU to CPU0
FoeHammered 2017-02-27 13:01:33
oscar mike golf i learned so much today thank y'all
nacc 2017-02-27 13:01:51
causative: if you really have an issue with cpu 0, that measn you probalby have a hardware issue.
nacc 2017-02-27 13:02:15
causative: most likely, given that you're playing a game on it, cpu 0 is really thread 0 or so
causative 2017-02-27 13:02:51
nacc, I have disabled the other 7 CPUs, andI'm watching my system monitor performance widget
causative 2017-02-27 13:02:55
so it's def CPU 0
causative 2017-02-27 13:03:33
also this is not just this one application, I have had similar freezes at other times, this is just when it's more of a problem
nacc 2017-02-27 13:03:59
causative: "CPU" is just the Linux terminology, it's really a logical thing, not a physical thing.
nacc 2017-02-27 13:04:20
causative: it seems incredibly unikely that only your thread 0 would have physical issues and none of the others

it's a single threaded program

nacc 2017-02-27 13:05:16
causative: do you understand cpu topology?
causative 2017-02-27 13:05:20
nacc, are you telling me that /proc/cpuinfo is purely logical and has no correspondence to my hardware, even t hough it lists 8 CPUs and that is my hardware?
nacc 2017-02-27 13:05:28
causative: when i said thread 0 it had nothing to do with your software threads
nacc 2017-02-27 13:05:38

For instance the command 'sudo apt-get install virtualbox-ext-pack' needs me to use the keys tab spacebar spacebar to accept agreement. Can this automated?
nacc 2017-02-27 13:06:10
Gongoj: you don't want to automate, genearlly, accepting agreements
nacc 2017-02-27 13:06:56
causative: no, i am saying that if /proc/cpuinfo says you ahve 8 cpus, it means you ahve 8 logical cpus. It does not mean you physically have 8 cpus. Which means that even if you did disable logical CPU 0, that if your hardware is that broken, there's probably something else wrong
causative 2017-02-27 13:06:58
nacc, I am not aware of an alternate meaning of thread than software threads, and googling doesn't turn up much, can you give me a link?

nacc, there may be something wrong, I did get some weird CPU pipeline errors some months ago though they haven't returned
Gongoj 2017-02-27 13:08:40
From the example I gave I don't know how to automate the accepting of the license.
causative 2017-02-27 13:08:43
but it seems it might be possible the error is just in one specific core
causative 2017-02-27 13:08:49
and I want to disable that core and see if it helps
causative 2017-02-27 13:09:00
except I'm not able to disable cpu0, just the others
UserUS 2017-02-27 13:09:46
causative: that will cause a logical failure, it will get bad blocks
nacc 2017-02-27 13:10:00

nacc 2017-02-27 13:10:06
UserUS: what? cores have nothing to do with blocks
nacc 2017-02-27 13:11:19

UserUS 2017-02-27 13:11:27

nacc 2017-02-27 13:12:15

Zambzz 2017-02-27 13:12:22
credel, well that didn't work 😢

Zambzz 2017-02-27 13:12:30

nacc 2017-02-27 13:12:31

Hello. I'm having some issues using MariaDB on Ubuntu 16.04. I install it with "apt-get install mariadb-server mariadb-client". When I run "mysql -uroot", however, I get "Access denied for user 'root'@'localhost'". I then run mysql_safe_installation and set a password for the root user, and I still get the same error over and over again when logging in with "mysql -uroot -p" and typing the correct password. any hint?
nacc 2017-02-27 13:13:21

nacc 2017-02-27 13:31:44
causative: so it doesn't really make sense to just try and taskset the one task you care about, other stuff is running too

you think I should try tasksetting all processes to fe?
