Thursday night
5-yo: "Daddy, can I get a night light?"
Dad: "Sure, buddy. I've got all sorts of glowing things. What do you want your night light to be like?"
"Rainbow!"
"Say no more."
How to write Java code that doesn't suck
2017-09-04 02:42 by Ian
It only takes one simple piece of knowledge to write Java code that has a runtime heap usage more inline with that of a comparable C program. I am writing this post as a public service to teach your engineers how to remove Java from their Java code.
I think I fried my first digit

This is a running log of my postmortem analysis.
Digitabulum r2 PCBs have arrived
2017-02-18 01:11 by Ian
The r2 hardware arrived Friday. Had CPLD images flashed by Saturday. I'm crazy-busy writing enough firmware for the ESP32 to test it. Until then, photos...
Digitabulum: Flex circuits, and a release choice
2017-01-05 23:46 by Ian
After 1.5 years, the digit design is complete, and is real hardware on my desk. This was easily the hardest (and most expensive) part of the project.
Digitabulum: Digit update
2016-12-14 01:48 by Ian
First articles of the flex parts arrived today. This is a panel as it arrives at the assembly house. This one was shipped to me as a representative sample that I can use for testing some EE parameters.
Securely wiping data with minimal tools

This was an email I wrote to some coworkers explaining how I securely wipe data. I am reproducing it here.
Digitabulum: Final digit layout
2016-10-19 02:13 by Ian
Fabricator is ready to roll with the flex circuits, after a looooong game of ping-pong and a few re-work cycles. Getting things right in such tight constraints was not a trivial task. And after more than a year of refinement, the digits should be landing on my bench around this time next month.
The state of my exposure to cryptographic libraries

This is a quick overview of the cryptographic libraries I have deep experience with.
The Wrongness: Route and Identity
2016-09-25 01:46 by Ian
Of all the species of Wrongness I commonly observe in the wild, the conflation of Route and Identity is of particular concern at layer 7 of the OSI stack.
