3 laps in Schrevenpark

René came up with the idea to run a couple of laps in Kiel’s Schrevenpark. However, somehow we managed to miss each other, so I ended up running 3 laps alone. Pretty hot outside, even in the morning hours.

I wonder where René is…

Quiz Question: How could you drop a table twice?

Kai Voigt — Sat, 10 May 2008 14:16:46 +0000

How can this happen?

mysql> DROP TABLE t;
Query OK, 0 rows affected (0.00 sec)

mysql> DROP TABLE t;
Query OK, 0 rows affected (0.00 sec)

Well, just use a temporary table.

mysql> CREATE TABLE t (i INT);
Query OK, 0 rows affected, 1 warning (0.00 sec)

mysql> CREATE TEMPORARY TABLE t (d DATE);
Query OK, 0 rows affected (0.01 sec)

mysql> DROP TABLE t;
Query OK, 0 rows affected (0.00 sec)

mysql> DROP TABLE t;
Query OK, 0 rows affected (0.00 sec)

I will add more such silly/hard/cool/whatever questions from time to time here.

My website is back

Finally, my website is back. After moving 123.org to a new home, I found some time to pick -again- a new blog system. For no particular reason, I’m running Wordpress now.

Enjoy and stay tuned.
