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 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.

comment Is there any practical reason to dual-boot Linux alongside Windows?
Sounds like you were trying to abuse the system a bit... Ubuntu is supposed to be a more "user-friendly" Linux distro, i.e. it hides things from you to keep less technical users from getting overwhelmed. If you want to do things like switching from Gnome to KDE in mid-installation, Ubuntu isn't for you.

For the record, no need to prefix with sudo if you're already logged in to the terminal as root.

comment How to copy files to an untrusted computer?
It would give you access to the other machine, and not even full access, just whatever level of access the user you log in as has. This is the way I've seen it done in the past (by some people who knew what they were doing) and what I'd recommend.

So by "untrusted" you mean that you can trust the other user with these files, but not with any other sensitive personal information?

comment What does the percent CPU mean?
CPU usage percentages are often reported out of 100% for each CPU individually, so the total amount of CPU power to be used in a dual core system is 200%, in a quad core 400%, etc.

comment How does one change user's home directory in Ubuntu 9.04?
It's not as complicated as it looks, they just had to explain in detail for people who aren't familiar with the process. All it really involves is (1) create partition, if necessary (2) mount partition (3) copy files (3) unmount partition (4) edit /etc/fstab (5) move old home directory out of the way (6) move new home directory to /home (7) mount new /home (8) check everything, and remove old home directory

comment How can I make it as difficult as possible to connect to the Internet from my “work computer”?
Yeah, probably not, unless you're feeling adventurous. But if you were, it'd probably be the best way to keep yourself offline. (Physically remove the wireless card and lock it in your boss's safe, and maybe melt the connector for good measure ;-)

comment What Linux distribution has the most up-to-date packages?
Gentoo sometimes gets new releases out the next day, and sometimes they have long delays. The latter is more likely for large programs or core system packages (like Python). But you can usually get around it by using an overlay (third-party repository) and/or by specifying that you're willing to use an untested version of the package.

comment How to work with multi-screen setup,what is it useful for?
Not all monitors can physically be flipped, though. Or... sure, any monitor can be flipped, but some of them are designed to be set in one orientation and don't have stands that will hold them in a rotated position. So you'd have to build some sort of makeshift stand to hold a non-flippable monitor. Easier, in my view: get a monitor whose stand allows rotating from the start.

I think at least the first extra monitor adds a lot more than 20% ;-)

SO = significant other (right?), for anyone who, like me, is taking 10 seconds to figure it out ;-)
