It's a tiling window manager written in Common Lisp, which means I can change any of the behavior on the fly. I guess you can do the same with xmonad, but I don't know Haskell, I do know a bit of Lisp.

Unlike a lot of tiling window managers, it does user-defined "static" layouts. You start with a single frame covering the whole screen. You can split that vertically or horizontally. You can then split either of the new frames vertically or horizontally, and so on. When I used to use i3 and xmonad, I'd get annoyed when my windows kept moving around and resizing whenever I opened/closed a window. Now I have a few different virtual desktops with layouts I find useful. Browsing on one, with a big frame for the browser and some smaller ones on the sides for xterms. Programming has half the screen for emacs, the other half for an xterm or two.

It takes a second or two to start, because let's face it, modern Lisp implementations are slow to launch, but once it's running it's quite responsive. Memory footprint isn't tiny (we're running a full Common Lisp system here), but I'd wager it's still smaller than KDE, GNOME, or Unity.

One thing I really loved was that the default keybindings were good. The default keybindings in WMs like i3 often eat a bunch of bindings for other programs--I had a hell of a time using i3 and emacs at the same time, for instance. Most of the commands are prefixed with a Ctrl-T, so you'd hit "C-t c" to create a new terminal, sort of like doing an Emacs command (C-x C-s). Yes, I know you want Ctrl-T to open a new tab in your browser; to send a Ctrl-T, you just hit it twice (C-t C-t). You can also add keybindings to the running WM using a little snippet of Lisp code, and if you like it, stick that in your .stumpwm file so it works every time. I left most things default but added Alt- to switch between desktops.

The thing about scientific computing is that scientists like to write MPI and Fortran. They just love that shit. And they are traditionally really resistant to any new programming model. So when you tell them they need to start using XYZ instead of MPI so their programs can actually complete at exascale *before* hardware failure, they get unhappy and instead implement things like checkpoint/restore that takes 70% of the runtime.

A "virtual android device" is an instance of Android-x86 running in a KVM virtual machine, which takes advantage of hardware virtualization instructions to give better performance. You could take the same software and install it on a desktop PC, assuming Android-x86 includes the appropriate drivers.

At least at my school, it was clearly (and frequently) explained what plagiarism is and exactly what happens if they find you pulling that kind of stuff. Now, maybe if you come in as a 3rd year or something like that you might be able to miss all the talks, but I think any school would be extremely remiss if they neglected to give that sort of orientation to incoming foreign students.

As a personal anecdote, semi-related, my girlfriend is from India. She has a cousin back home who is paying somebody to attend college for her, so she can get a teaching degree. It blew my mind that yes, it's considered acceptable to do this--her whole family knows, and at least the ones over there don't see any problem with it.

Cloud

+ - Cloud starting to look like big data center->

DillyTonto (793644) writes "According to a story on ITWorld, the cloud computing market as a whole is starting to look like one big data center. Diagram it and you have OSI layers, hardware, software, middleware, storage, desktop management — the whole schmear, but spread out across the whole Internet.
Two problems: You can get your whole data center from the cloud, but having different elements provided by different companies, separated by hundreds of miles, makes coordination harder. Second: There are so many new players, underfunded players and big companies wanting to rope customers in for more than one service at a time that the whole industry is ripe for consolidation.
So what happens if you hire 15 companies for SAAS, DAAS, Paas, etc, build a lot of data-center capabilities in the cloud hoping standards will catch up so you can migrate workloads or SAAS data from one cloud to another, then watch those companies all get bought up by bigger companies with no incentive to get their systems talking to someone else's and are too big to take your complaints seriously?"

I have helped write non-trivial programs in Go. It's quite pleasant. I think the big reason Google hasn't bothered to provide "adequate tooling" is the developers. That is, I think many of the creators and big users prefer to just work with a plain text editor rather than an IDE. There's a reasonably decent Emacs mode for Go, but it's readable enough without any syntax highlighting, and gofmt will fix your indentation and such for you. As for the debugger, well, there's http://blog.golang.org/2010/11/debugging-go-code-status-report.html (very old but even then they already had GDB support going), but as the first line says, "When it comes to debugging, nothing beats a few strategic print statements to inspect variables or a well-placed panic to obtain a stack trace", which is all I ever used to debug my Go code--and found it reasonably painless! Oh, and regarding generics--I'm not sure they'll ever go in. It is proposed CONSTANTLY on the mailing list, and Pike et al always indicate that they're not interested.

Thufir's a Harkonnen now.
