Tool Tips

Submitted by BinksUK on Thu, 05/18/2006 - 12:05

Whilst writing the fault logger I came across a need for "tooltips". You know the kind, a little floaty box when you hover over a certain piece of text or icon giving extra information to the user. A small web search showed many a possibility, some free, some not so free. I eventually settled on a freeish solution until it became apparent that I'll be selling the fault logger on and I would get into issues along the line.

Scale

Submitted by BinksUK on Thu, 05/18/2006 - 04:51

Distance on the ground = map scale X distance on the map

Dg = scale X Dm

Dm = Dg / scale

A simple mathematical model where only the connectivity information is preserved.

Consists of:

Points - vertices
Lines - arcs
Numbers on the arcs (e.g. distance) - weights

Advantages: a simple visual representation of a journey by giving the main pieces of informatin - place names and distances.

Disadvantages: You loose out on further information and visual representations.

Types of Statistical Investigation

How big is X? - Summarizing
Is X bigger than Y? - Comparing
Is X related to Y? - Looking for relationships

Reviewing Statistical Techniques

Technique	Definition	Purpose
Line Graph	Where data values are plotted along two axis and joined together.	Used to give a graphical view of data in order to make interpretation easier
Mean	The average - sum of all number in the batch / batch size	An average value of all numbers in a batch to give an overall representation
Weighted Mean

Math's Investigation

Pose the question
Collect the data
Analyse the data
Interpret the results

The statistical investigation cycle - once you get to interpreting the results you may find new questions are raised and the cycle begins again.

Tired

It's been a long week. I'm ready for another holiday I think.

The Fault Logger has been properly released at work, although still only internally to the ict department rather than whole school so they can continue to find bugs for me. All good I think. So now I can move on to implementing some of the other features, the fun stuff

Word Wildcards

Submitted by BinksUK on Mon, 05/08/2006 - 15:38

Every now and again I need to remove unwanted linefeeds and carriage returns from a piece of (usally pasted) text. As this is not a frequent job and my memory is useless I usually spend a while trying to remember the exact codes for doing this. It can be done via words find and replace feature but what to replace? Hopefully this will help next time I'm stuck.

Warm Snow

Submitted by BinksUK on Mon, 05/08/2006 - 06:56

I've long maintained that the only thing wrong with snow is that it's cold.

If you could get warm snow all would be right with the world.

It is now the warm snow time of year. As I sit and write this I can see the little flakes fluttering down through the window.

Obviously it's not real snow, I haven't completely lost it, but it looks like snow, it's fluttering about like snow, it's moving in the wind like snow, apart from no snowballs it's just as good as the real stuff.
