I can usually work for relatively long periods of time without needing the internet, or needing it only sporadically, and mostly while using emacs to edit various kinds of text files.  While I'm doing this, I usually turn off power to the Airport wireless radio on my MacBook Pro to save battery power, then turn it on only when I need it. Using emacs trains you not to use the mouse unless

I needed to generate a plot in Matlab for data over a triangular domain.  It took quite a lot of googling to find the answer, which ended up being relatively simple, so I thought I'd post the solution here. The main trick was to use the fill command to draw a triangle over the unwanted parts of the plot.  Note that I also make the background color of the plot white, which I ALWAYS do because the

The quick and dirty:  Git Dashboard is a lightweight git repository manager and Dashboard widget that I wrote to organize local repositories. I use git for a lot of stuff.  I find it useful for document projects (latex mostly) as well as code projects and research projects.  The associated repositories are, to some extent, a snapshot of my work life, and therefore the more organized they are and

git svn is a great way to work locally using git for remote svn repositories.  The basic workflow is rebase, hack, commit, hack, commit, etc, rebase, dcommit.  You'll get lots of google results by just searching for git svn.  One feature that's really nice is interactive rebase.  For example, to interactively examine the last 8 (local) commits and have the option to delete or combine commits (

A pretty common task when editing c/c++ programs is to switch between the source and header files (i.e. file.c or file.cpp and file.h). I had a handy keyboard shortcut in vim to do this and, despite my newfound appreciation for the concept of Emacs, this was one of those things that in practice I was sorely missing. I actually sort of expected it to be built in... M-x

I'm liking emacs. I still miss some of the vim commands, particularly numerical prefixes (I know, in emacs you can do C-u to prefix a command, but it's just not nearly as elegant) and the "repeat last edit" command ".". But on the whole, I like how integrated emacs is, how customizable it is, and actually a few of the editing commands (one of my new favorites is C-x ; to set the comment column

I've been playing with Emacs lately. The MO of Emacs is to avoid leaving it any more than absolutely necessary, so there are packages for doing all kinds of stuff. One of those things is posting to blogger. It didn't take too long to find this article introducing g-client, which can be downloaded from google here. Downloading and installing it were relatively painless, except that you need to

So I saved up some birthday and Christmas money and got a couple new items of camera gear. I got the Nikkor 50 mm f/1.8, which for less than $150 is really a no-brainer. It's super sharp and fast (there's a reason they call it the "nifty fifty"). I like it a lot. I also picked up Manfrotto 190XB tripod legs and a 484rc2 quick release head. It's not the biggest tripod but that was kind of the

If you're like me, you tried Keynote 2009 and - while Keynote continues to be a superior presentation tool - decided that it wasn't worth the cost of upgrading. If you're even more like me, you created at least one presentation in Keynote 2009 during the trial (or converted a Keynote 2008 presentation to Keynote 2009 and tweaked it a bit), and were then quite dismayed to find that you could not

I develop a lot of c++ code on my mac for cross-platform applications, and I've often wanted a convenient way to export a list of source files belonging to a given target in an XCode project. That way when one of my colleagues wants to create a new project on another platform (e.g. Visual Studio or makefile) I can tell them which subset of the source tree to compile for a given application.

I remember taking it around the time we were searching for Janis Joplin's house on Lyon Street, so I guess that makes it Upper Haight still, but the lower end? We walked all the way from the MUNI stop at Carl & Stanyan down the full length of Haight to Market Street, had lunch at a place called Cafe

I'm the proud new owner of a Nikon D80 DSLR!  Or at least I was a month or so ago when I got it.  I don't update this very often, just when the mood strikes.  Anyways, I had been scoping DSLRs out for a couple months and decided to finally go for it (permission from my wife to spend a bunch of money was also key).  I picked up the D80 with two lenses; 18-55 mm f/3.5-5.6 VR and 55-200mm f/4-5.6 VR

The whole "work blog" thing died after about one day, so that's gone. I'm really interested in getting an SLR this year (after the credit card is payed off from Cancun/Christmas/etc/etc), so maybe I'll go back to a regular blog kind of thing and post some pictures. Why not?Here's a picture of the Old Church of St. Andrew here in Newtown. I took it late in the afternoon and was able to get the
