2458 - Cant connect to local MySQL server through socket /tmp/mysql.sock
Q Have you ever had the error message Can't connect to local MySQL server through socket '/tmp/mysql.sock' from your PHP program. It's one that I see quite often, but it doesn't seem all that well documented ... so what's the cause, and the cure? A The error message seems to occur if you delete y ....

2457 - Railway Arithmetic
1 + 1 = 1 If you have an early morning round trip out and back to a residential / suburb, and a similar evening round trip, you're just providing a single commute opportunity to the origin point of the train. 2 + 2.5 = 8 If you take the two round trips of the first example, and add two more round t ....

2455 - Lua examples - coroutines, error handling, objects, etc

2451 - Gypsy says
Gypsy has asked me to point out following on from yesterday's entry that although she appeared in three out of the four family pictures (and was the ONLY one to appear multiple times, I noticed!), she did NOT appear in the picture with the food.

2450 - Family Gathering at 404, The Spa
Yesterday's lunch was the first time in goodness know how long that the whole family living here abouts came together for dinner, so I'm going to make a very rare break from my 'norm' and post a family photo which they all knew I was taking. From left to right, my Dad, son Chris, his wife Delene, T ....
