comment Does segfaults mean bad memory
In case you didn't know, "bad memory" (and this sure looks like it) is often "memory that's come loose from its socket". Do the memtest and if that fails, try removing and re-seating the RAM first; 'tis a bit less expensive than replacing it.

comment Does segfaults mean bad memory
If a program is running while a kernel is resident, it cannot check the locations the kernel lives in. If you suspect hardware memory errors, no memory should be trusted (or, all memory must be tested). Memory tests on a live system cannot do the whole jobe.

comment Upstart reload does not work
Good puzzle. Since reload sends a SIGHUP to the named job, I'd suspect that the pid file as defined in the upstart job is not set correctly. Of course this guess is confounded by stop command working properly. So I'd dig through the system logs for /var/log mentions of my_app and add relevant entries to your question.

Upvoting based on amusement value is probably contrary to SE intentions, but I do intend to cite your Maxim 37 in the future.

Almost any editor worth using that has dictionary support should allow you to specify multiple dictionaries. What editor are you using and have you checked its documentation?

comment Not able to do password-free access to remote machine!
What distribution are you using? Almost no one ships a real rlogin by default any longer because it is horribly insecure. OpenSSH sometimes provides an alias for ssh called rlogin which never even looks at .rhosts because that's part of the horrible insecurity. See the answer by @maxschlepzig for how to remote shell properly. If you have the option of installing an old-fashioned RFC1282 rlogind, don't, It's a Bad Idea.

comment How to remove a USB drive without worrying if its been unmounted?
I concur. I also like my answer because it made me think about the design of thumbdrives and how the intentionally cheap USB connector wound up with a completely unanticipated consequence ("What's a thumbdrive?" would have been a utterly valid question in 1995).

comment Communication with MX records
+1 with minor nit: the number associated with an MX entry is a preference not a "cost" where lower numbers have higher preference (so it kinda looks like a cost).

comment How can I recover suspended processes after restarting X?
Given the way xlib works (the actual connection from X client to server) it has historically not had any provisions for reconnection to a new server. Someone may have come up with a mechanism, but since the X connection is stateful, I doubt it.
