I use Emacs and just switched to Cinnamon when upgrading to Trusty Tahr. It somehow stole the control-space keybinding, which I use in Emacs a lot; it is used for setting the current mark, so I can cut or delete a region of a buffer. This is also used for the autocomplete feature in Eclipse, which is one of the main reasons I use Eclipse.
Solution found: some built-in thing called IBus binds that for setting the input method. I like the input method I already have set up & I don’t need to change it, so here’s how to disable that: answer on askubuntu.com.
I bought a Lite-On eTDU-108 DVD writer, as a companion for my MacBook Air which lacks a built-in optical drive.
Using this drive with a Mac is strange because it has a lid, so the Mac cannot physically eject the media. This leads to odd circumstances such as when you tell the Finder (or iTunes) to eject the disc, and it makes the icon disappear and suddenly it’s back, as if you had inserted it into the drive again at superhuman speed.
Most of the sequences of ejecting discs that I came up with resulted in error messages, failure to eject the disc, spinning beachballs, or unplugging the USB cable from the drive in frustration. I finally figured out the right sequence to eject a disc from this drive when it’s connected to a Mac.

Interviewing at large tech companies is different from interviewing at a startup. Here are some tips about how the interview process differs, and some specific advice for how you can prepare.

If you make a screen with a name using
screen -S foo and then try and reattach later using
screen -R f[tab] it doesn’t work. It only completes the full name as seen in
screen -ls which starts with the PID of the detached screen, like
9972.foo. Not very convenient. Why can’t it just complete using the name you gave it?
Someone else solved this problem three years ago but nobody accepted their patch, and now /etc/bash_completion.d/screen has been overhauled and the patch no longer applies.
I updated the patch so it works and resubmitted it to Ubuntu.
If you don’t wanna wait, grab the code from this gist and do this:
sudo patch /etc/bash_completion.d/screen screen.patch
This will probably work on Debian too since that’s where the completion script came from.
In the past few weeks, I’ve had a few conversations with web developers and back-end engineers who are unfamiliar with Ruby, in which I’ve tried to explain how Ruby can be nearly as expressive as Perl (tiny amounts of code can accomplish a lot) while being as readable as Python or Java. In fact, I think that Ruby’s expressiveness can remove distracting boilerplate code, allowing compact expressions to be far more readable than a more verbosely written version of the same algorithm.
