Nothing interesting about me. This is not the user you are looking for. Move along. Move along.

comment Linux: ps command's output is randomly different than expected, can you find the reason?
It works for me. Tested on Ubuntu 14 LTS and Fedora 21. Maybe CentOS 6 is just too old. I didn't realize it was a new thing.

Instead of etime use etimes. Put the s on the end.

comment Although 80 and 443 are system ports, how are most web servers able to bind to them anyway?
On Linux you can also apply CAP_NET_BIND_SERVICE capability to the program or you can use iptables to redirect a system port to a regular port.

You have your answer. What you didn't ask was how to do this better. Use etimes to get seconds. Then you have no weird parsing of the time to do.

comment Linux - Is there a way to prevent/protect a file from being deleted even by root?
Taking this a bit further, you can use squashfs or cramfs which are compressed and read-only. It needs a special tool to build the filesystem.

comment Write caching in linux
I am not sure about Windows but Linux may defer non-sync writes up to the sysadmin's configured time. Defaults are 5 or 60 seconds depending on the filesystem.

comment Would the data on the RAID Card Cache and Drive Cache be lost when a kernel panic happens?
The machine's power distribution board or motherboard might also fail. Although personally I've seen more RAID card failures.

That can also be caused by a messed up router/firewall. See lwn.net/Articles/92727

comment Packet loss on between firewall and uplink?
I've seen these intermittent problems caused by either bad cable or failing ports combined with link autonegotiation. It glitches and thinks it is 10Mbit half, for example. It might work fine forever just by forcing the connection type. Remember to do both ends.

comment 4TB drives using an ARC-1231 controller?
@StefanLasiewski: A new RAID controller is as likely to fail as an older one. If really new, even more likely.

comment Why is 1 of my 24 CPUs Pegged at 100%?
Couldn't that also be a driver bug or a piece of bad hardware interacting with a driver with no error recovery? Or maybe software calling into the kernel in a tight loop.

comment Force edit txt file that is in use windows
I remember seeing programs that would forcably break file locks. I believe they did it by attaching to each process with the lock and closing the file handle from inside the process.
