This might appear to be a strange first topic in a sequence of blogs about Computing, but its content is directly relevant to a current GCSE controlled assessment task – although, of course, I’m not going to say which one!
One of the problems with coming new to Computing is that (without wishing to sound like Donald Rumsfeld) you don’t know what you don’t know. Most teachers can probably see the name of a topic with which they’re not familiar, read about it, and teach it, but modular arithmetic is a simple mathematical concept and very useful programming technique that isn’t mentioned in the National Curriculum and I haven’t noticed it in any GCSE specification. If I were to ask you, “What is 10 ÷ 4?” , what would you say? I suspect that most adults and KS4 students (and, indeed, most programming languages other than Python) would say “2.5”. That’s basically all modular arithmetic is – division with remainders, where we’re particularly interested in the remainder part. Noughts and Crosses. Computers do some miraculous things.
A computer can beat the World Champion at Chess, even fly a plane more skillfully than a human ... How do they do it? How can a lump of silicon and wire appear to be smarter than a human...? Everything clever a computer does is ultimately down to a person - a computer scientist in fact - writing clever instructions: rules to be followed. Every thing you have ever seen a computer do, was just it obeying the rules written by a computer programmer probably years earlier.
With the instructions on this web page, even your kid brother can play better Noughts and Crosses than you can! You will struggle to beat the instructions at any rate. WINDOWS93.
From Ada to Zuckerberg: History's most important IT people - Computing. Readers of Computing will know better than most how wide-reaching and fantastic the effects of IT have been, and continue to be, on the human race.
The leaps and bounds technology continues to make year in, year out are staggering. But who are the people that made information technology what it is today? From the raw conceptualism of a computing algorithm or building the first transistor-based processor, to executing established practice to create the World Wide Web or social networking, Computing has identified the key individuals in an epic chronology that spans over 400 years. But who are these people who built IT from nothing to the global phenomenon to which we owe our careers and lifestyles today? Who is the king of relational databases, and who is the queen of mobile phones? And who pioneered the induction motor and AC electricity, but ended their life flogging unlikely energy weapons to global superpowers while taking care of injured pigeons?

Digital photographs are actually just spreadsheets. When you take a photo, your camera measures the amount of red, green and blue light hitting each pixel, ranks them on a scale from 0 to 255 and then records those values as a spreadsheet. Matt Parker found a way to actually open digital photos as spreadsheets in Excel.
The process involves cracking the digital photo file open, scraping out all of the numbers and putting them into the cells of an Excel spreadsheet.

Moore’s Law, the observation that overall processing power for computers will double every two years (or more accurately that the number of transistors on integrated circuits doubles), is a fascinating computing concept that is very easy to demonstrate to students by mapping the history of computing over time.
I have always thought about it in terms of hardware, but last week I came across this excellent illustration of the Law, as shown by Eidos’s famous character Lara Croft of the popular Tomb Raider series.

Remodelled ZX Spectrum production set to begin. 14 January 2015Last updated at 08:48 ET The new ZX Spectrum Vega features an SD card slot and joypad controls Production is set to start on a remodelled version of the ZX Spectrum, which will come pre-installed with 1,000 classic game titles.
Nottinghamshire firm SMS Electronics will manufacture the Sinclair Spectrum Vega at its Beeston factory. The machine, which has been developed by Luton-based Retro Computers, is due to go on sale in April. Sir Clive Sinclair, who launched the original ZX Spectrum computer in 1982, is backing the venture. Mark Goldby, managing director of SMS Electronics, said he was hoping for "big things" from the new machine. GamesYouLoved. Google Code-in 2014 - Home page.
