Vote For Bob and save our country's wildlife

I don't usually get too involved in politics other than taking an interest and of course voting but there is one thing I'm passionate about and it is our country's wildlife. I see all sorts of examples of where our wildlife and conservation is taking a back seat to in particular development (e.g., the +Yorkshire Wildlife Trust first conservation area at Askham Bogg, near York which is under threat right now - see With a new election coming up soon we need more politicians up for election to state what they are going to do to protect our wildlife, reserves and conservation areas.

The RSPB have started a campaign "vote for bob" to make sure our politicians know we are concerned about our natural places. If you want nature back on the agenda then please vote at

Windows 7, Screen blank after a wake up from sleep

I'm putting this here as a reminder to myself and in case it helps anyone else.

I have an NVidia GTX660 (latest driver) and an ASUS pb278Q connected via the display port. I have the power settings to turn off the monitor after 30 minutes and mostly leave the machine turned on. However, often when I come back to the machine and hit a key on the keyboard or wiggle the mouse the machine wakes up but my screen is blank.

Perl script to rename Nikon RAW files and now export MakerNotes

I use a Nikon D7100 camera and Nikon's Capture NX2 software. Recently Nikon have released a beta of some new software (here) they've got another company to produce and when it goes live Nikon will stop supporting Capture NX2. I wrote about the problems this will cause me and thousands of others at Nikon Capture NX is dead, Nikon have stolen our property and left us high and dry. Now it appears the subject of that post might be a bit over the top (I was really annoyed when I read the beta announcement of the new NXD beta) but the fact remains I (and countless others) have got thousands of hours of image editing that could potentially be lost. What is the problem?

Nikon Capture NX is dead, Nikon have stolen our property and left us high and dry

The thread on dpreview that started this off is at here. Basically, Nikon have got Silkypix to write a new editor (NXD) for Nikon and will stop supporting Capture NX. You can try the beta of NXD here. The beta feedback page is here and the official comments include things like:

New release of Perl DBD::ODBC with support for MS SQL Server Query Notification

I just released the 3rd development release of DBD::ODBC (1.39_3). Apart from a few bug fixes and other changes (see below) this release adds support for MS SQL Server Query Notification. Query notification allows an application to request a notification from SQL Server when the results of a query change. Once set up you can block on an execute call waiting for the query to change. Here is an excerpt from the pod:

New Perl DBD::ODBC 1.47 release

I have just uploaded DBD::ODBC 1.47 to the CPAN.

This release does contain significant changes in behaviour for unicode builds of DBD::ODBC so I hope when I warned you months ago you tested it.

Thanks to everyone on the dbi-dev list and irc that helped me work my way through the unicode issue.

I'm now going to sit back and wait for the usual rush of reports from everyone who didn't test it.

See below for changes since last full release.

1.47 2014-02-19

Full release of the 1.46 development releases.


Speed comparisons of HTTP clients in Perl

Back in 2011 I wrote Faster HTTP usage. At the time Curl was the winner for the way I use HTTP. Since then a few more HTTP client modules have appeared on the CPAN and I was nudged by Tim Bunce to repeat my testing with the newer Hijk and HTTP::Tiny.

Renaming Nikon photograph files with Perl

I have owned a Nikon D3100 for a few years now. I generally have it set up to take nef/raw images and in camera processed jpg files so I end up with a load of files on my SD card called _DSCNNNN.NEF and _DSCNNNN.JPG. I sometimes edit the raw/nef files in Nikon capture NX and write a new JPG out as _DSCNNNN_copy.JPG and upload it to picasa or Nikon or google plus.

How to fix printer head jam on Kodak Hero 5.1

This morning I had a printer head jam on my Kodak Hero 5.1 and despite searching on the net I could not find anyone with a solution except a youtube video for another Kodak printer.

Obviously, you follow this at your own risk.

Perl DBD::ODBC 1.46_2 released - You REALLY need to test this release

I've just uploaded DBD::ODBC 1.46_2 to the CPAN. In the process of writing Some Common Unicode Problems and Solutions using Perl DBD::ODBC and MS SQL Server and github repo I discovered a serious bug in the way DBD::ODBC can attempt to insert unicode characters into char/varchar/longvarchar columns. This experimental release fixes that issue but it does mean this release contains a significant change in behaviour. Since 1.46_1 yet another unicode fix was added too.
