Spa website: more planning

Implement this.

With the above implementation should likely come a few extra types of classes of data.
The only problem with adding more types of data is that a different type of admin page needs to be written. Currently the admin page can edit the entire site, which is nice. I think the all encompassing design currently in use, is best, since it can be tailored to many different uses. Continue reading

PPC Software Upgrade to WM6.1

I installed Binky’s 3.4 ROM today.
Comparing this install to the K’s Rom 1.31 Lite I had previously on the device, it looks better. More memory available for program and Storage.
Storage: Total 70.98MB, in use 3.07MB, Free 67.91. Program:Total: 48.68, In use: 21.48, Free: 27.2MB.
After installing Point UI 1.51a,
Storage: Total 70.98MB, in use 5.28MB, Free 65.70. Program:Total: 48.68, In use: 24.52, Free: 24.16MB.
So after PointUI installed and running, I am only loosing 3MB. Much better then the 6MB lost in my last setup.

So far, both PointUI (with the PointUI optimized font rendering on) is much much faster. Also (I guess due to WM6.1) applications take less time to launch.
Overall, certainly an improvement.

Archiving photos

I’ve been thinking about how to archive my photos, for a wile now.
Do I keep the RAW file? Should I just keep 16bit PNG/Tiffs instead? What about the RAW editor that created the file that stores the changes to the image?
Also, how to keep myself and my wife happy, with high resolution images that she can view on her laptop, but don’t take a lot of time to view wirelessly.

So I think I’ve decided on a solution.

Keep the RAW files, with the accompanying .bib file that Bibble creates to store the modification data.
Monthly move data that is older then 1 year old to a separate folder that should get backed up, and then erased off the computer.

When working on images, and time comes to save them, save a “Proof” jpeg file which is 1024×786 resolution, and a “Full” jpeg file which is the full resolution.
The file name convention should be:
Proof/Full-description-date-time.jpg/CR2
This should allow for chronological sorting of files.

When images are copied from the camera, they are put in the “Unsorted” folder.
In Bibble, “Download” the files from the Unsorted folder to the appropriate location like I currently do.

Autoslalom solver

Just some thoughts:
– Use the coordinates of the cones as initially thought
– The initial (and subsequent) paths should consist of vectors. A starting point, a direction (absolute) and a length.
– Steering change should be just that. An increment in angle of the next vector.

I think usage of curves should be avoided. I will use straight line segments/vectors (short ones and long ones) to make up the entire path.

Set an initial value for max acceleration, max deceleration and max centripetal acceleration.

Java

Started learning Java.
Installed Eclipse, with the java development tools, and already wrote and ran the “hello world” program! Wohoo!

Listing of some sites that are useful, as I find them along the way:

A good introductory book to Java is “Thinking in Java”. Free copy here:
