Charging four 35AH 12V batteries from empty

Posted at age 30.

In preparation for the burn, it’s time to charge the batteries I use for my solar setup. I was surprised to find them registering only 5 volts on my multimeter; something in the solar regulator must have been discharging them. This at least gave me an opportunity to see how long they take to charge from empty and how much power that uses.

Random numbers

Posted at age 30.

In my Arduino projects, I had been using the typical pattern of seeding the pseudo random number generator with a reading from an analog pin like randomSeed(analogRead(A0)). Anecdotally, the results seemed nowhere near random. If I had a program that selected from three modes, the first mode would be the selected mode the majority of the time.

Starting with DigiKam

Posted at age 30.

I’m starting to figure out my photography workflow on Arch Linux. Previously I used Adobe Lightroom for organization but still did almost all editing in Photoshop. I never quite figured out an editing workflow I was happy with in Lightroom. But now I get to circumvent that step and figure it out on Linux. :-)

Automatically relaunch unresponsive Mac app

Posted at age 29.

The Insync client on my macOS 10.12.5 installation freezes at least daily, which I only notice when I find files are not syncing across my computers. My hacky solution was to write an AppleScript to check if the client is unresponsive and create a launchd agent to start the client any time it is not running or crashes (different than “Not Responding”).

Coveting my neighbor’s citations

Posted at age 29.

Every once in a while, I write a blog post where I want to put a few footnotes. More frequently, I reference sources. My writing is far from academic, but I figure the least I can contribute is pointing readers (usually just my future self) in the right direction. When I consider the best ways to accomplish these goals, I am reminded of all the other rigor and consistency related issues I have yet to adequately address. The Buddha was right: life is suffering.

The Black Swan

Posted at age 29.

I am so far enjoying “The Black Swan: The impact of the highly improbable” by Nassim Nicholas Taleb (Random House, 2007). In searching briefly for a summary both to inform the rest of my read and to send to Yizhen, I found a review and critique by David Aldous from January 2009. I have no strong opinion on Aldous’s main disagreement about the cumulative impact of non black swan events, but I appreciated more perspective. I should check out the other critiques mentioned and Taleb’s “shorter and more cohesive account”, “The fourth quadrant: a map of the limits of statistics”.
