Python saves the day...again.


I've been having some challenges with my drawing algorithms not showing the data properly on the screen. Everything's looking pretty great so far in terms of curve smoothness, but the peaks in the impedance plot were not showing up where they


Weird site issues


For some reason, the debian-unstable version of ntptime was returning me a time that was 4 hours behind from what it should be. My time zone and everything seemed to be fine. I couldn't figure out what was wrong.</p><p>Doing an 'apt-get upgrade...


Fun with NSImage...not


Last night I managed to round my time off to 40 hours. The majority of my time was spent trying to figure out how to speed up my NSView. Since the NSBezierPath was simply following my FFT's window size, it would really bog down around the 8192...

Calculating costs


After the past weekend, the "hours counter" is up to 37. This is measured in terms of productive hours, and not just the hours I've simply set aside to work. Unfortunately, the first 12 or so hours are purely an estimate, and that's a generous...


Challenges abound...


There has certainly been a lot of buzzing in my brain the past few days regarding the use of Bezier paths and lots of points to be plotted 'nicely'.</p><p>Thankfully, I took the geometry course we had offered in the summers of even years (?) which...


Progress so far


I'm going to try keeping a bit of a development log to look back on one day for this software. Perhaps it will help me realize where I spent too much time, or what concepts I'm having the most trouble with.</p><p>Also, I find that by putting my...
