2166 - Crossrefering documents with uniqueness and inconsistency issues - PHP proof of concept demo
The cross-referencing of documents - where one document contains a human readable reference to another - is very common. And so is the requirement to convert those cross-references into a appropriate links. The Example Let's say that I have chunks of data of up to 160k, relating to up to 4000 ima ....

2165 - Making Regular Expressions easy to read and maintain
Have you ever seen a long regular expression made up of so many special characters that you can't read or maintain it very easily?

2164 - Updating my public profile - Graham Ellis
It's when delegates start asking me how old the picture of me in the back of the training notes is that I realise I should update my picture from time to time - not that people choose the person to teach their PHP course based on a photo of the tutor.

2162 - Admins thoughts on banning a member from a forum

2161 - Get it right ... if it goes wrong, it takes so much effort to sort out!
When things go wrong, it gets very expensive and time consuming indeed to sort them out ... something that I was reminded of in a "personal message" I have just sent to a member of our Coffee Shop Forum. I wrote: "My first priority where something is posted which could have legal implications for t ....

2160 - PHP - getclass v instanceof
It should be very rare that you want to say "what type of object is this?" in PHP - or in any OO language; that's because with a correctly implemented class structure, you should have polymorphic effects that cause your code to perform the correct operation whatever object type you run in on. Howeve ....

2159 - A long day to guess where
It's only quarter to eight in the evening ... but I'm exhausted to sleep - probably due to the quarter past five start from home this morning. Perhaps that was crazy, but for on site course between 150 and 200 miles from home, I'm torn - to travel out the night before, have the hassle of unloading ....

2158 - On the roof of a Melksham Spa House
Over the weekend, we have been working (with far more skilled friends) to get our home / office at "404" linked to the hotel at "48" via a directional wifi setup.
