I've been using Linux and Unix professionally since 1995, mostly in Linux-related sysadmin/systems architect jobs supporting academia. I generally know my stuff, but am very happy to learn something new and to be corrected when I'm wrong. Currently, I am the Fedora Project Leader.

comment Intel HD 4400 external display with linux
On mine, it shows up in the bios. You might have disabled optimus/nvidia. I did on mine initially until I discovered this exact issue. (There are some experimental hacks to get Optimus working, but easiest is to just use the Nvidia card. Should work with Nouveau, unless you need serious 3D)

comment Intel HD 4400 external display with linux
Is this one of the Thinkpad models with "optimus" dual Nvidia and Intel graphics? I discovered that with mine, the Intel just isn't connected to the external ports; you must use the Nvidia card.

comment Does LVM impact performance?
You certainly can change how work is done. For example, I can give you directions to a location via GPS coordinates, or by streetnames, or by local landmarks. Different ways, but you still have to walk the same path. The time it takes to look at a paper map vs. following your phone's instructions may differ slightly, but ultimately it's negligible compared to the walking time.

comment dd writes to CF with delay
Can I watch the progress of a sync operation? might be helpful — you can see a bit more of what's going on behind the scenes, and watch as it transfers.

comment Get files from SFTP server and manipulate in memory
Possibly it wasn't in RHEL 6.0 and released in an update? I can check, but the right answer here is probably you should update your system in any case. :)

@PackedUp What CentOS version? Just checked RHEL7 and Scientific Linux 6.5 (what I happened to have at hand) and both support it.

@PackedUp What version and from what distribution? Or, build yourself, and make sure to link against libssh2.
