Organizations often try to adopt a software development methodology, in hopes of reducing the risk of cost and schedule overruns in their software development project. Veterans of previous methodology adoption attempts roll their eyes or actively resist, while less experienced team members drool in anticipation of some order and predictability. In this post I describe how software development methodology adoption efforts can fail, based on my own experiences.
This is a personal perspective, so it doesn’t go back all the way to the early days of computer science. It starts when I started paying attention, which was in the 1990s. Nevertheless, I think it’s pretty accurate with respect to what was going on in the 1990s through today (late 2015).
Once upon a time, in the final years of the 20th century, there were some experienced software folks who had been through some successful projects and some failed projects, who had developed a sense for what to do and what not to do in certain situations.

Bruce Schneier summed it up well: the good guys have to secure all the doors and windows; the bad guys only have to find one. In a nutshell, that’s why security is hard. Real-world security has to deal with that problem all the time.
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.
