One last blog entry


Today I released a major new version of Mathomatic, version 16.0.0. I don't know where to publicize it, Twitter is so bad that my posts don't even show up in a search for "Mathomatic". Google+ seems to just want entertainment. Freecode.com seems to be the only place a free software author can post things and be seen. Thank you for Freecode.com.

Mathomatic version 16.0.0


This latest major release features new functionality and bug fixes, too many to list. Code, documentation, and user interface improvements and corrections were made. Everything has been cleaned up and tested to perfection. It does everything I could imagine that is helpful, except for logarithm support. I will add logs when I feel better. See The Mathomatic Website.

I hope you like it and learn from it; it is my best work. Please provide feedback, if nothing else. Thanks for reading my blog.


Signing off,

George Gesslein II

I think I will not be blogging on Advogato anymore. No one can comment on my posts, and it doesn't seem to be reaching anyone. So, logging off...

Function entry support

Now Mathomatic can accept any function strings, like f(x+y), by typing "set special_variable_characters ()" at the beginning of a session. It copies the entire function string into a variable name, so no operations can be performed on it, but it can exist and be displayed in any expression where everything else works. Functions can then perhaps be taken care of by another program if needed.

This is just added as a temporary measure, until I get better and add more function support to Mathomatic. Otherwise any function entry gives the error: "Named functions currently not implemented, except when using m4."
Trig and many other standard functions are handled with m4 Mathomatic (the program named rmath), which is usually included in any recent Mathomatic package.

Mathomatic in Debian

Had my first Debian package update uploaded today.
Mathomatic is now maintained by me in Debian.

This may be a good thing, now I have the ability
to create and/or maintain any Debian package that
needs it.

Mathomatic version 15.6.3 is released today, it is a ton of work, but I had to do it before I end up in the hospital again. I am feeling like I am going to lose consciousness all the time now. Not a pleasant feeling.

My Internet is totally controlled by an unfriendly alien force. I hope it doesn't hurt me. It has removed all social contact from me. I just keep doing good in my little cage.

New Advogato Features

New HTML Parser: The long-awaited libxml2 based HTML parser code is live. It needs further work but already handles most markup better than the original parser.

Keep up with the latest Advogato features by reading the Advogato status blog.

If you're a C programmer with some spare time, take a look at the mod_virgule project page and help us with one of the tasks on the ToDo list!
