I'm a postdoc doing research in high-energy particle physics. I also have a hobby interest in computer programming.

You can find me on Twitter, or check out my blog and personal website! Or you can email me at stack@ellipsix.net.

However, please don't contact me through any other channel about something that should be handled through this site. If you do, I'll probably just tell you to post it here.

comment Software with Malicious Intent binded to executable?
It's asking how to tell whether there is a key logger in a piece of software, which isn't a programming question. The fact that the software was written for the OP by contract is mostly irrelevant.

comment How to uninstall files and software from a Solid State Drive (SSD)
+1, for anyone who doesn't need high security, deleting is done the same no matter what kind of drive you have (magnetic or SSD).

comment Basic security practices for desktop Ubuntu
@Daisetsu: Ubuntu does have automatic updates set up by default, and for the reason Florian explained you may not even need a firewall. Some other Linux distros require you to set these things up manually. (Those distros are generally intended for people who want a lot of control and actually prefer not to have the firewall etc. automatically configured)

comment Basic security practices for desktop Ubuntu
Mostly these tips are relevant for a server setup, not a desktop. It is true for Linux in general, though, that viruses and malware are not much of a problem, at least not compared to Windows, for exactly the reason stated.

comment sudo access for desktop actions in Gnome/KDE?
@Jakobud: if you think that's difficult, try doing the same thing in Windows ;-) You do have a point, though: allowing privilege escalation for file copy/move operations could be a useful feature that KDE does not currently have, probably because nobody's felt the need strongly enough to implement it.

comment Quick, Linux-compatible unit-aware calculator
+1 So am I, although my user interface (the Qalculate plasmoid for KDE) doesn't offer a way to express a result in specified units. I work around it by dividing my result by the units I want. I forget whether the full interface, if it even still exists, can do that. (Just so it's clear: even with the UI limitations, it's still my favorite calculator for anything I don't need Mathematica for)

@quack: well... it doesn't really answer the question, just says that the problem went away.

comment rm -rf not erasing directory
This sort of thing should probably be left as a comment, not an answer.

When I started reading I thought you were going to say that MS Support had instructions for what to do when your cat walks across your keyboard ;-)

comment Need a Linux command that takes much time
Yes, and I wasn't asking why he needs it, I was asking what exactly he needs. There's a difference.

comment Change desktop background at school
Depending on how friendly your school's IT people are, you could always ask them about it. Not that I'd expect them to change the policy, but they might at least have something to tell you about why changing the background is restricted behavior.

comment Need a Linux command that takes much time
It actually depends on your requirements... do you need this command to be doing something non-trivial while it's running? For instance, are you looking for something that will access the hard drive for a certain amount of time? Or rearrange values in RAM, or transmit continuous network traffic for that time? Or do you just want something that will not return for a certain amount of time? (That's sleep) And what exactly do you mean by "much time"? Some specific amount of time, or indeterminate-but-longer-than-X-seconds, or what?

comment What is the easiest way to free space on a hard drive?
Indeed, cron the concept is cross-platform (and I will state for the record that I am a Linux user, and have never been a "Windows aficionado")

comment Commandline complete list of commands
I think you can set the environment variable PAGER to /usr/bin/less (or whatever the full path to less is), and then bash will use less for paging.
