A quick FYI: IBM DB2 9.7 isn’t compatible with DB2 9.5 or 9.1 servers by default. The symptoms of the incompatibility are that some (but not all) queries result in an error which looks like: SQL0805N Package “NULLID.SQLC2H21 0X4141414141504161″ was not found. The solution is that the servers must be made compatible with the newer [...]

Recent versions of DB2 have support for Unicode, if your databases are flagged as Unicode-enabled. This is a good thing, so you may have done it without thinking too much about the consequences. After all, i18n is good, right? Unfortunately there are some major snags to be aware of. In particular, in Unicode-enabled databases the [...]

I just became aware of an interesting JavaScript ‘feature’. The code y = x % 1; is equivalent to y = x – Math.floor(x); because ECMA-262 says: … the floating-point remainder r from a dividend n and a divisor d is defined by the mathematical relation r = n − (d * q) where q [...]

My attention was drawn to a trainwreck of a discussion on Reddit, which was triggered by another trainwreck of a discussion on an enterprise Java community web site. The vexed question: Is Java pass by value, or pass by reference? My short answer, carefully phrased: Java passes both object references and primitive types by value. [...]

Recently on the ruby-core mailing list, someone asked why Ruby doesn’t have multi-line comments. I did a few searches, and didn’t find much discussion of the evils of multi-line comments. I thought it was common knowledge that they were a bad thing and a historical mistake made by Kernighan and Ritchie, but apparently not. So, [...]
