Buy a new Dell laptop and you too could get this support

Ok, so someone is bound to say I'm just using a blog entry to complain about a company and although I am, it was not me that got the bum end of a deal from Dell. My friend, does not use computers every day and is self employed in the building industry but needs better records for his tax and the production of bills and would like to watch a DVD or two. He found a laptop he liked but could not find anyone selling it and found something almost equivalent from Dell.

Upgrade to Ubuntu 10.04 broke my Oracle SQL Developer

I just upgraded from Ubuntu 9.10 Karmic Koala to 10.04 Lucid and my Oracle SQL Developer stopped working entirely. I didn't bother trying to look in to it as my SQL Developer was rather old anyway so I downloaded and it didn't work either. Seeing the warnings on the SQL Developer page about supported JDKs I first checked what I had installed.

New 1.24_2 development release of DBD::ODBC

I am happy to announce another development release of DBD::ODBC. Many thanks to everyone who has contributed to this release and especially to all my friends on the #dbi irc channel and perl monks. My intention is to add a lob writing method and full support for DBI's DiscardString and StrictlyTyped attributes in the next development release before releasing a final development release and finally a 1.25 full release. To support the new odbc_lob_read I've had to delay the binding of columns until the first fetch instead of as before when the result-set was described. This should not have any adverse effects but you are advised to test this release as without any feedback it will move to the next final release. The changes since the last full release are:

character|binary lob reading in DBD::ODBC

I currently maintain DBD:ODBC and needed to obtain a lob (large object) in chunks. It doesn't really matter why but in general the lob is very large and I can process it in chunks in my Perl code so it makes sense to read it in chunks instead of read it all in one go (thus requiring loads of memory). DBD::ODBC does not have this functionality currently.

Why is taint mode so slow?

In the last few days on and off I've been trying to locate a problem with a fairly complicated Perl daemon using POE which was taking a huge amount of time to return a large file via LWP::UserAgent. It's taken a while since in reality we were not doing a simple HTTP GET and the circumstances under which the problem occurs are difficult to set up. However, I've at last tracked it down to taint mode.

Devel::NYTProf saved us again and raises a question

Not for the first time a Perl POE daemon in our development system seemed to be taking a long time on certain requests. It is a large amount of code and although we had our suspicions we've learnt the lesson now - Devel::NYTProf is so simple to use we had no hesitation in running it on this daemon. Instead of:
perl program_args
you simply run:
perl -d:NYTProf program_args
then a nytprof.out file is created and then you can generate the HTML report and view it with:
mkdir report
nytprofhtml -o report
firefox 'file://report/index.html'

ODBC - The Connection Process

A great deal of issues arise in the dbi-users mailing list and to me personally concerning ODBC connection issues so I thought I'd describe the ODBC connection process here (with a slight Perl angle since I look after DBD::ODBC). The information here should be of general interest to anyone using ODBC.

DBD::ODBC 1.24 official release now on CPAN

I have uploaded the official 1.24 release of DBD::ODBC to CPAN. Many thanks to everyone who has helped with this whether it was patches or testing. Here are the changes since 1.23: =head2 Changes in DBD::ODBC 1.24 May 14, 2010 Minor change in Makefile.PL to only use NO_META if ExtUtils::MakeMaker is at least at version 6.10. Reported by Chunmei Wu. Minor change to test rt_50852 which had wrong skip count. =head2 Changes in DBD::ODBC 1.23_5 May 6, 2010 Added advice from Jan Dubois (ActiveState) on building DBD::ODBC for ActivePerl (see

DBD::ODBC 1.23_5 released - soon to move to official 1.24 release

I the last few days I released another development release of DBD::ODBC 1.23_5. I've been waiting for smoke testers to attack this release and then I will do an official 1.24 release. Since very few smokers actually run the test code I'm going to look at Test::Database for the next release - if you are a smoker and have Test::Database setup for DBD::ODBC I'd love to hear from you (really). 1.23_5 contains the following changes since 1.23: =head1 CHANGES =head2 Changes in DBD::ODBC 1.23_5 May 6, 2010 Added advice from Jan Dubois (ActiveState) on building DBD::ODBC for

Testing DBI's DBDs

I've maintained DBD::ODBC for some years now but one thing that constantly causes me problems is finding enough testers to be sure a development release is good enough to be released officially. CPAN Testers do a great job (and I joined the clan for a while until the throttling issues last Xmas and now I wait for CPAN Testers 2) but very few (if any) have a data source set up to a real database. Mostly the reports I get are PASS but when I look at them there was no actually data source set up so no real database tests actually ran.
