365 - Letterbox Pictures
There's a convention that pictures are pushed using a 4:3 or 3:4 aspect ratio and those are known as landscape and portrait formats ... but I've taken a few pictures over the last few days that seem to lend themselves naturally to the 2:1 ratio You might almost call this a "superlandscape" view o ....

364 - pu daily and p hourly
Tcl is a command based language - everything you do uses a command that starts with a command word such as puts to output information or set to assign a value to a variable. The while command (yes, it really is a command) lets you define a block of code that's to be run repeatedly while a conditio ....

363 - Greetings from Edinburgh
I slept in this morning ... woke at 06:30 and - yikes - had two hours of work to do before training, so "The Mouth" is shorter and later in the day. And, yes, I'm fighting the Edinburgh traffic each morning from shore where I'm staying to mountain top where I'm working. ....

362 - The ireallyreallywanna operator
In Tcl, any character (yes - any character) can appear in a variable name, though making use of variable names that contain - for example - spaces adds a needless complexity to your coding. Groups of special characters can be protected from the Tcl interpreter by wrapping them in curly braces, and i ....

361 - Binary Large Objects or bars
When designing a MySQL table, it's vital to choose the correct data type to hold your information. One such possible is a Blob - a binary large object - which can hold any byte stream that you like (choose the subtype based on maximum size). Ideal for data like images which you won't want to searc ....

360 - Spring turns to Summer
Taken yesterday in the Herefordshire countryside - a little further from home than most of the pictures that I put up on "The Horse's Mouth". This will be forming part of my "clickable map" demo - where I'm putting up pictures from all around the UK. See ... Work in progress (Click on map ;-) ... ....

359 - Chicken soup without the religion
Lisa's just back from a trip to the USA and was commenting on how strong the religious right is becoming there. I celebrate the fact that in our lives / in the UK we can take different views and positions on politics and religion from our neighbours, yet still get along well with them and hold them ....

358 - Use standard Perl modules
If you're writing a piece of code and you think "surely someone has done this before", then you're probably right. Chances are that someone has written the code, debugged it, tested it, documented it, and may even maintain it and have a lot of facilities that you would love to have but cannot justi ....

357 - Where do Perl modules load from
When you're writing a Perl program, you're strongly encouraged to use existing code that's already been written to perform common functions. Not only does this save you time re-coding, but it also means you get code that's already tested and proven, and there's only one piece of code to be maintaine ....

356 - Sudoku helper or sudoku cheat
Have you seen the sudoku puzzles that are being published in the Daily Telegraph and (I think) the Los Angeles times? There's a whole group of addicts out there and helper and forum web sites too. Lisa pointed the puzzle out to me recently (no, she's not an addict!) with the thought of providing ....
