I don't know what the fuss is about the latest iTunes update. Then again, I don't use iTunes. Meh. 8 hrs ago

Robot Sunday: Self-assembling, flying drones

Here’s another scary step towards a robot uprising.

A group of researchers are developing robots that dock together and take off by themselves. Called the Distributed Flight Array, the group of robots roams around independently and assembles randomly to form a flying vehicle. The modules communicate with each other to control the platform’s flight.

I’ll host it later for a one-click install. Update: Here is the one-click install.

Display user account info in a Windows AD

(Hell just froze over! I’m actually using Active Directory! In Windows! {Well, I did use Active Directory in a previous job, but that was because of LDAP…} {And I’m using waaay too many exclamation marks!} Anyway: it’s the command line — gosh, I miss the C:\ prompt. Not!)

To display user info in an Active Directory domain controller:

C:\> net user username /domain

Zypper clean-up

So I was having this problem updating some Kerberos 5 patches in my SuSE test environment — apparently a patch RPM was broken. I tried fixing that by downloading them directly, not using

sudo /usr/bin/zypper up

but

sudo /bin/rpm -Uvh krb5.patch.rpm

instead. No dice.

Since there was no yum clean equivalent in the Zypper version (0.6.201) in my server, I promptly deleted all sources under /var/lib/zypp/cache, thinking I could just refresh the cache later on. Well, it didn’t quite work that way.

Zypper complained about missing sources, so I had to look for the source files that refer to the cached source directories:

sudo grep -l Source.garbage /var/lib/zypp/db/sources/*

and removed them as well. I did another run of sudo /usr/bin/zypper up and I was able to install the patches successfully.

There must be a better way of doing this…

Robot Sunday: World robot population

The numbers are in (with caveats, of course): there are 8.6 million robots in the world.
