Why stop at twelve?
View image | gettyimages.com There is an election coming in Britain and so politicians are setting out their stalls. Education Secretary Nicky Morgan has now said that her priority will be a “war on innumeracy” and an insistence that children who leave primary schools should know their “twelve times tables”. But why 12? Until…

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…

Free software hex editor
I have noticed that my free software hex editor (hexxed) – which is licensed under the GNU GPL – does not really come up in any searches, so here’s another entry to boost it. It’s a bit crude, but it does some things well (e.g., display unicode and switch endianness) and it will run anywhere…

So what happens next? bash-3.2$ java -jar hexxed.jar -u usage: hexxed [options] -b,–block use block:offset address output – default is linear address -be,–bigendian interpret data…

Adding vi-like functionality to Hexxed
I have decided that I will model the keyboard interface for Hexxed on vi. I know that is not what many/any coming from outside the Unix world will expect, but then there are plenty of Hex editors out there and I want to make one that will appeal to at least one niche. As I…

Making some progress with the hex editor
Well, the hex editor still feels like a death march project but “I’ve started, so I’ll finish” and I have made a little bit of progress today, and it handles unicode characters (see screenshot). I am not aware of any hex editors doing that (though I am sure some do), so it feels like a…
