anderson: Server Migration (RootBSD)

Finally getting around to migrating my server (which is currently running at a dedicated hosting place) to a virtual server over at RootBSD (http://www.rootbsd.net). The virtual server is very snappy and feels like a bare metal box so far. Reliability has been good too, and it is 1/3 the cost of my dedicated hosting plan. So far, so good.

anderson: Tweet tweet!

Just in case you do not already know, I set up a twitter account for FreeBSD, that auto-tweets from feeds sent in from the freebsd.org RSS feeds. It keeps you up-to-date on things like releases, security notices, and FreeBSD bloggers’ posts. The twitter account can be found here:

anderson: Page 56…

The game is simple:

  1. Grab the nearest book.
  2. Open it to page 56.
  3. Find the fifth sentence.
  4. Post the text of the sentence in your journal along with these instructions.
  5. Don’t dig for your favorite book, the cool book, or the intellectual one: pick the CLOSEST.

Results for me:

“When a high vacuum had been reached, first the connecting tube, and then the bulbs, were sealed of; they are therefore of the same degree of exhaustion.”
- Nikola Tesla: Experiments with Alternate Currents of High Potential and High Frequency.

Nikola Tesla is the most fascinating and probably one of the most forgotten inventors/physicists to walk the Earth. If you don’t know who he is, turn off your computer, your lights, etc, and throw away any fluorescent bulbs, and while you are at it, turn off your radio.

anderson: Sicko

I just finished watching the movie ‘Sicko’. Makes me sad to see the United States in is such a poor position health care wise. Why does Cuba have a better health care system than USA? That makes no sense, and it pisses me off. Why are the healthcare companies destroying our nation? Is it worth the money? I guess it must be.

anderson: PUFFS for FreeBSD?

I’ve been considering porting PUFFS (NetBSD’s kernel implementation of FUSE) along with reFUSE (the library that goes along with PUFFS) to FreeBSD.  I wonder what the interest is in this?

anderson: FreeBSD Cross Reference Online

After being a heavy user of Robert Watson’s FreeBSD cross reference site (here) which indexes many different OS kernels, including FreeBSD, NetBSD, OpenBSD, Linux, Darwin, OpenSolaris, and more. It’s quite impressive, however, I often found the need to see the entire OS, and I’m mostly interested in the BSD’s. I ended up building a local version on my laptop, so I could take it with me wherever I went (it’s handy when you are on a plane). After using it quite a bit, I realized that I also wanted a version available to me on the web, that I can also use as a reference for others. So, I built it, and made it available here:

FreeBSD Operating System Cross Reference

Feel free to use it as much as you like.

In a future entry, I may show the steps and changes I made to get it all running, if there’s enough interest.

anderson: Utility File Systems

What’s next? We all know about devfs and similar file systems, and many of us use unionfs or nullfs. However – what other utility file systems would be useful, that we haven’t built yet? I think tools like FUSE have given a lot of people some very creative ways of thinking about file systems, but how can that be extended into other areas?
