I mainly use it for development however i do play some games. The disturbing thing is that the computer is loud on pretty simple tasks.
Here are…

I'm looking at the new MacBook Pros and trying to decide between the Core i7-4960HQ (2.6 GHz) and i7-4850 (2.3 GHz). I've found some synthetic benchmarks comparing them, but I haven't found a lot of data, so I'd appreciate any pointers to good comparisons for the Haswell family (especially these two…

I've got an Intel i7 3770 CPU and am generally quite happy about it.
However when I am just browsing around without programs running in background it seems to underclock itself quite a lot. This is not a real issue, however there seems to be a small hiccup (0.1s maybe) when it clocks itself higher…

I am currently choosing between Intel Core i7-3770 (quad, Ivy) and Intel Core i7-3930K (6 cores, Sandy Bridge-E). This machine will be used for both work (Adobe, Autodesk software, graphic and coding-related) and gaming.
Even if some applications I will use are capable to utilize all 6 cores at…

According to http://net-snmp.sourceforge.net/docs/mibs/ucdavis.html#scalar_notcurrent ssCpuUser, ssCpuSystem, ssCpuIdle, etc are deprecated in favor of the raw variants (ssCpuRawUser, etc).

I've noticed that there are sometimes (large) differences between the reported total CPU usage and a summation of the per-process CPU utilization given by apps like top and wmtop.
As an example: I recently ran a git filter-branch --index-filter on a fairly large repo, with the index-filter command…

I have a Ubuntu 12.04 server which sometimes dies completely - no SSH, no ping, nothing until it is physically rebooted.
After the reboot, I see in syslog that the oom-killer killed, well, pretty much everything.
There's a lot of detailed memory usage information in them. How do I read these logs…
