V-Twin study

Visualizing the geometry and sound of a Harley-Davidson v-twin engine: p5.js sketch. Run this animated sketch at the slowest speed and observe that the flywheel mass pushes each cylinder through compression, without direct assistance from the power stroke. Also, the longer exhaust period of 405 degrees is produced by the left (rear) cylinder.

Strategic search

If we divide a circle into 360 equal angles, we end up with one degree incremental vectors in which we can look around ourselves on a planar surface. When we misplace something, we can head off in 360 different directions. If we then allow for up and down angles of equivalent size, then for the sphere surrounding us at every moment, there are 41,253 directions we can look. Given all these options, we must choose wisely.

Technically, the number of directions is computed from A=4πr² where r=360/2π. [Square degree]


Two timing twin tuplets

A rare temporally numeric occurrence is about to happen two days from now.

Almost like an astronomical event, but human made.

Loss of image quality in Word 2007

Finally, a mystery is solved. When saving a document using Word 2007, image quality would decrease. At first, I thought it was due to saving as a PDF. Turns out there is an option to fix this issue and it took a long time to find it.

Compression can be disabled on a per-file basis using the following steps:
Click the Office Button, and then click Save As.
Click Tools, and then click Compress Pictures.
Click Options.
Click to clear the Automatically perform basic compression on save check box.
Click OK.
In the Compress Pictures dialog box, click Cancel.

Note: Clicking OK on this dialog will not prevent the issue from occurring.

You can also modify a registry setting to prevent basic compression from occurring by default.

Update: Another option is to double the size of the document. For example, if targeting a size of 8.5x11, then set the document size to 17x22 and adjust margins and font size to compensate. When saving to PDF, the images will still be down-sampled to 220dpi, however, this translates to 440dpi at double the size. If printing, scale the document to 50% in the printer settings. Images will be crisp. Or...move on to libreoffice.org
