Free software to chop up your JPEGs
As a public service announcement – if you need some software (on Linux but may well compile and run on other systems if they support Qt) to chop a big JPEG up into smaller files, I have written this (in my case to support building a test set for a neural network). It’s at https://github.com/mcmenaminadrian/TestSetCreator and…
Proprietary software as a false economy
I recently had to fill in a form for the Computer Science Department at the University of York. Like, I am sure, any computer science department in any major world university, York is a “Unix shop”: research servers all run Linux and I guess the academics who aren’t using that are – as I am…
Open source alternatives to “Junior Librarian v3”?
My partner is a teacher in a primary school and has special responsibility for teaching English – which also means she’s in charge of the school library. I don’t have any personal experience of the library and Lorraine is not an IT or database expert, so what follows may be a bit sketchy… …anyway, the…
New, improved Hexxed
I have not had much luck in hunting down what is wrong with my code or the Xerces-c SAX2 parser – but I do think I have successfully updated by hex editor, Hexxed, to handle 64 bit (ie >4GB) files. Indeed it performs rather better than vi for some editing tasks (Hexxed has a vi…
President Obama’s campaign and free software
It seems a row has broken out between staff on President Barack Obama’s re-election campaign over the fate of the free software it produced (the article linked here refers to it all as “open source” but on this issue I tend to side with RMS and not ESR). Actually I do not blame the DNC…
Well, what else was I going to do? This works and that means I think BINSIC does too. It’s not quite a fully functional BASIC – try as I might I cannot get GOTO or even GOSUB to work inside loops (though I might do better if plough on with the GOSUB stuff), but I’ll…
Why choice in software matters … a story from the real world
Ten years ago today something happened that has had a significant impact on many millions of people across the world … Mozilla 1.0 was released. Above all else Mozilla, and it’s leaner, fitter, offspring, Mozilla Firefox, is the most important piece of free (as in freedom) software ever produced. For sure, it stood on the…

Who needs a free hex editor then?
OK, Hexxed, the hex editor I have been working on, is nowhere near being finished but it does seem to be in a good enough state to find testers. It’s very rough round the edges but it will allow you to open, edit and save files. I have given it a Vi-like interface and I…
