Has passed about 2 months from last post, but no news from WinSid, I focused mainly on hardware and mathamatics in this period, but WinSid will be back soon with new software, ideas, how-tos (something about hardware, maybe) and mathematics.
Bye.

[Android] New cycling software idea

Yesterday, while I was cycling around for Brescia, I had an idea about a software for Android:
A sort of “bike-dock” to track your tracks, taking notes of all informations;
Basically it should be a Google Maps map (offline, no network connection required) where you choose your track (maybe with basic navigation informations on display), where each point or each “segment” can provide many informations, also with comparison with the same segment in previous exits, obviusly many informations are displayed on the screen also during the ride, like a compass, current position on the track, slope, mt over sea level, velocity, time, and many other things…
Seems to be interesting and “cheap” compared to the most exapansive bike’s computer…

In two days I’ve written a quick GUI for the Sudoku solver, up to now it’s really simple, you can only insert numbers in the grid and ask to the software to solve the puzzle.
New features are coming, as said before:
- Loading from text files and image scanning (via drag’n'drop)
- Progress of the solving process in a progress bar
- Index of “difficult” of the puzzle
- Informations about solving process (time, validity, etc)
I leave you with a screenshot 
Byee, good night!

As said before (about 10 minutes ago ) we’re working on a sudoku solver, here some technical details.
By now it uses the backtrack method to search a solution to the puzzle;
It’s a quite simple algorithm:
The software compiles a list of suitable numbers we can put in an empty cell, then, for every of these numbers, it “watches” what happens if we try to fill others cells, given that cell with the choosen number, if we arrive to an empty cell with an empty set of suitable numbers our first choice was wrong, so we try with another suitable number, and so on…
It seems very very expensive, in fact it is, but it’s enough to solve almost any puzzle in <1s, even if, if one builds a particular puzzle, it can take much more time: an example is this one which takes 2min on my machine (Centrino Dual-core 2Ghz, 4GB of RAM under Linux).

Today WinSid opens its blog, we’d like to start with some informations about our past, present and future.
WinSid born in 2007 from the idea of two young programmers of building new softwares.
During the years the things changed, a member of us “abandoned” the project (even if, now, he’s coming back, maybe ), but WinSid never changed and continued to provide free softwares!
The future? Well, now we’re working on a Sudoku solver, it’s almost done, but the graphics isn’t ready and we wanted to add some premium features (like image scanning and recognition…)
See you on the next post!
