Fix journal in an HFS+ file system
December 15, 2011
Yesterday my external Western Digital disk (which I use for Time Machine, among other things) stopped mounting automatically when I plug it in. This may *cough*definitely*cough*have something to do with me unmounting it forcefully while it was doing a backup, since I was in a hurry. Disk Utility reported everything was OK with the disk, but it still failed to mount. Upon poking a bit deeper, I found these messages in the logs:

WANT: Topbrewer - Scanomat

via scanomat.com I remember joking in grad school that we should've had coffee-on-tap so we didn't need to walk all the way down to the kitchen. Seems my dream has come true. I want one of these.
Remapping Mac modifier keys on Emacs 23.3
November 27, 2011
I just switched from Carbon Emacs (which is old Emacs 22.x) to Emacs for OS X Modified on my Mac (which is a Cocoa app, and Emacs 23.3). One of the unwelcome changes was that the Emacs 'Meta' modifier is now by default mapped to the Option key and not Command as before. But this gave me the opportunity to learn how to map the Mac keyboard modifier keys arbitrarily.

via theinspiration.com One time on a plane from Brussels to Chicago, I was trying to make space in the overhead for my backpack, by moving a large bag with a flowery stamped design. A large tattooed, biker-type guy across the aisle says to me: "please be careful, I'm transporting a china set in there". Never judge people by their appearance :)

Quadrocopters are really getting popular for research, and for a reason - they are seriously cool. Arms / grippers have already been used on them: They can also do ball jugling: Have precise movement control: And do mapping: Tip of the rotor blade to Axel Tanner for sending me these.

All the apps on my iPhone
October 31, 2011
I’m doing some cleanup and reorganization, and captured my current app setup as a reference point. Here they are. Quick note: The first screen is my most-used apps (some are going out now, like 2Do which I've never liked too much, but was the best way to sync tasks with Outlook, which I'm no longer forced using). Second screen is all my folders. Third and fourth screens are my girls' screens, with the games they use when they borrow my phone.

What's New in CFEngine 3: Making System Administration Even More Powerful - O'Reilly Radar
October 28, 2011
CFEngine is both the oldest and the newest of the popular tools for automating site administration. Mark Burgess invented it as a free software project in 1993, and years later, as deployments in the field outgrew its original design he gave it a complete rethink and developed the powerful concept of promise theory to make it modular and maintainable. via radar.oreilly.com I contributed to this article by Andy Oram on CFEngine 3.

New job, new book
October 19, 2011
Today I have two big announcements to make. First, as of this week I have a new job, I am now working with CFEngine AS, the company that develops and maintains cfengine. As you know if you read my blog, I am a big fan of cfengine. It is a mature and able tool that provides extreme flexibility and power to system administrators. The company is full of energy and with very interesting projects to make cfengine even better and more popular than it is today.

Dennis M. Ritchie, R.I.P.
October 13, 2011
Dennis Ritchie passed away last weekend. He was one of the great minds in systems research and development, father of the C programming language, and one of the big contributors to Unix, both of which power the Mac on which I'm typing this, the iPhone on my desk, the Windows machine I use at work, the servers on which this blog is hosted, and much of the infrastructure both you and I use to connect to it.

Farewell, Steve. Thank you for all you did for the computer industry, for design, for music, for telephony, and for so many other aspects of our lives. You will be missed.
Gene Schultz, R.I.P.
October 3, 2011
A few days ago I learned through Spaf that Gene Schultz had had a severe accident and was hospitalized. Later we learned that the accident was apparently caused by an earlier stroke that went unrecognized. Yesterday, October 2nd, during the afternoon, Gene passed away. I met Gene about 15 years ago while I was a grad student at Purdue. I met him initially at a couple of conferences, and later while he was visiting Purdue for some time.
