The most likely maths behind the alleged petrol-pump price scam being reported on Facebook.
I don’t normally share this kinda thing …
Unless there’s bad maths involved!?
On Facebook usually if a post starts “Ok so I’m not normally one to share things like this but…” then it’s down to some marketing genius trying to dole out product links cloaked as hot tips. So, when I saw this post I assumed that it was something along those lines. Instead (at first look at least) it appears to be a report of over-charging for petrol:
“Now I heard about garages starting to clock the pumps to charge you more than advertised so I started putting the test to the theory and low and behold…they were right! Charging me more for my fuel…Bast**ds! Now I can’t belive I never actually checked this before!
As you can see, 1 Litre should cost 123.9 pence, when I put exactly 1 Litre in it came to 125pence!”

So, is this for real. And if it is why would the company advertise the “scam” right there on the pump for everyone to see?!? Read the rest of this entry »
Test of various editors and IDEs for writing Python for beginners.
PR4E (Python) – Programming for everyone
Writing Python for beginners
I’m doing a Coursera course from the University of Michigan called Programming for Everyone (PR4E). Writing Python direct in to the web interface for exercise submissions is a bit clunky to say the least. So I’m curious what apps other beginners are using to actually write their python code?

Advice and experience with a baby sling.
Using a baby sling
My experience of slinging
We had a huggababy sling that was great for us. However there are about a million different slings, approximately, so I’d suggest you find a “sling library” and try a few out. Usually the people running it will sell the slings but IME they’re very familiar with the slings and are interested as much in making sure you have a good experience slinging as anything.
Using your sling
When baby is titchy tiny you can lie them sideways, within a few weeks they should be able to be upright (depends on your and baby’s shape). Huggababy have a page showing different ways to wear their sling.
Personally I couldn’t get on with the long piece of stretchy fabric baby wrap we bought from eBay and don’t like all the straps on the “modern” style ones (like Baby Bjorn carriers). YMMV. Read the rest of this entry »

How to extract web history information from an Android device.
Phone internet browser
History, URLs, Cookies, etc.
Unauthorised use of my wife’s phone led me to wanting to see which sites had been accessed. So I thought it best to put what I’d learnt in to a quick blogpost on how to extract information from my Android phone (Samsung Galaxy Ace) about recent history of URLs visited and other browser stats and metadata.
You’ll need to have a rooted phone AFAICT. This is how I did it, there are of course other ways:
- Use a root enabled file manager to go to the folder
- Copy the files over to your main computer (I placed the copied files on the non-root accessible sdcard and then mounted the phone as a USB drive).
- Use an SQLite browser to open the files.
What information is available

New puzzle game
If you like puzzles and enjoyed the recent “2048” craze as I did then you’ll probably like this – Game About Squares from Andrey Shevchuk. It’s been likened to Sokoban by some, that may or may not excite your neurons. Either way it’s a curious diversion that should last you at least one lunch break.
I’ve created a couple of walkthrough videos for levels 0-10 and 11-20 inclusive. More might follow … let’s see how I get on!
If you or anyone doubted the author’s geek credentials then you’d only need to look so far as the game’s statistics page to ascertain that this guy is the real deal!
