comment Linux cache evictions
No - vfs_cache_pressure controls the ratio of meta data vs pagecache retention (at least according to the docs I've read and the experiments I've run)

comment Can I read what CCFLAGS were used for building a binary?
Thanks Shadok - if you add this as an answer I'll accept it. In my case the code was compiled with gcc 4.5 :) but the binary in question has been stripped :(

If this really is a SSD you might want to reformat it to align the erase blocks with the partitions.

comment Fast way to copy a large file on a LAN
Runing rsync against a file accessed over NFS means that the entire contents of the file needs to copied over the network at least once. You don't need a daemon to invoke a client/server rsync - just run it over ssh. (it's theoretically possible to invoke the remote end over telnet / rsh - but rather silly to run such a service in practice - ssh doesn't add a lot of overhead).

comment Importance of fsck at boot with Journalled filesystems?
psusi - what have you been smoking? " Disks do not report writes as completed before..." - yes they do. "enable the write cache, which is disabled by default" - not on any disk I've ever configured. "barriers are used to prevent reordering" - but you said I was "conflating ordering with barriers"

comment Run unix command precisely at very short intervals WITHOUT accumulating time lag over time
I think it's also very probable that the programs porg has tested block while running the intended process - which logically they should do to avoid killing the machine they are running on.

comment handling right click with single button mouse (tablet)
For simplicity I'm probably going to go down the noVNC route - which makes it much simpler to swap the event strings in Javascript, or use xmodmap -e 'pointer=3 2 1....' serverside (with a timer to restore)

comment Ethernet Sniffing Embeded Device
My vote would be for wireshark. You might also want to get hold of a cross over cable in case the device acts as a hub / router / bridge.

comment How can I autostart GDM on Fedora 15?
Did you check what runlevel (fedoraproject.org/wiki/Systemd#How_do_I_change_the_runlevel.3F) you were booting into? Not familiar with upstart on Fedora, but I believe chkconfig can still be used to add/remove services from runlevels.

comment What is the appropriate value of vm.swappiness when using zram?
"increasingly fast"? On the fly compression has been performing better than direct disk I/O for more than the past decade (its never going to be faster than memory access - that's not the point)

What is it that you're wanting to configure? What is it that can be configured in ssh which overrides / is equivalent to the data in /etc/hosts?
