Is there a reason to use `top` over `perf top`?

2013-11-10 Thread Elazar Leibovich
It seems that while top lists kernel provided statistics per process which is somewhat interesting but not all that useful, perf is really sampling the system, and gives a real picture of who's hogging your system, which is usually why you've started top in the first place. Let me give a trivial e

How do I even debug this?

Hi all, At home, I have a highly sophisticated media server (i.e. - a bash script that schedules, using "at", a "cat /dev/video0 > video.mpg", and schedules another "killall cat"). We usually just order the Yes transcoder to jump to the proper programme at the right time, and coincidentally tell t

BTW - why do you need tab completion every time? Can't you assign a shorter alias? What about writing a small CGI script and moving to a web interface? It'll be much more future proof IMHO. On 11 November 2013 06:36, Amos Shapira wrote: > For a start: http://code.google.com/p/connectbot/issues

linux system acting as access point/router?

2013-11-10 Thread geoffrey mendelson
I want to set up a laptop to act as a mifi type router. The reason is that I already have it, and it has a 6 hour battery. What I want to do is normally use the Wifi as a connection to my home network, which already has routers, DSL lines, DHCP servers, etc. When the power is out, and they are

While the point of perf not being available to non-root out of the box are valid (though, it's just apt-get install linux-tools + echo 0|sudo tee /proc/sys/kernel/perf_event_paranoid away, and it's the best bargain you'll ever make), IMHO this is indeed apple vs apple comparison. The goal of top's
