Techtarget's Java ServerSide Symposium 2009 Impressions

Just got back from Vegas where between Wednesday and Friday a small-ish java conference was taking place. This was my second one, the first being five years ago in 2004. Of course it's hard not to compare, and I find myself doing it anyway... I can't help but feel that the excitement has left java server software. Remembering one of the very first java conferences in Sydney 1995, when it was still almost academic and less of an industry conference, I feel like we've come to an end of an era. The tedious reality of maintaining enormous enterprise systems built over the the last decade has sinked in, and unfortunately there is nothing exciting about it, but everything difficult and complex. Those less fortune whose systems took advantage of EJB1 and EJB2s will suffer the most, as those are dying technologies and are rapidly being replaced by simpler more component friendly software.

Binary PostgreSQL installer broken when used on RedHat EL5.3 / Dell PowerEdge 2950: Hangs server reboot.

This is a very quick post that would hopefully save someone else hours of hitting the head on the wall like I did. If you are installing RedHat Enterprise Server 5.2/5.2 x86_64 on Dell PowerEdge server, be aware of the following issue with PostgreSQL binary installer offered by EnterpriseDB. After installation the server is unable to cleanly shutdown due to the fact that the binary installer does some voodoo with libtermcap - basically making this system library be used from inside postgres installation folder. Because of this, kernel can not umount /usr (or whenever your PostgreSQL is installed) and hangs the shutdown. Solution: Build PostgreSQL from the sources. They are ahead in minor version number anyway. Thanks.
