- I am really enjoying my setup to Measure Humidity and Temperature of your home with Phidgets and Prometheus.
- turns out humidity in the kids room fluctuates drastically (between 40% and 60%) depending on the various activities taking place at home (showers, cooking etc.) OSS Grafana is fantastic for visualizing the daily fluctuations - it shows when the dehumidifier kicks in and combats steam coming from wet children and freshly cooked stuffed peppers.

On a vaguely related topic the Phidgets SBC collecting temperature and humidity at home is an armhf v7 board. I recently compiled some Go code for it (lpsh) and learned about the different GOARM options. Turns out as of this writing Go supports the following ARM architectural families:
| Architecture | Status | GOARM value | GOARCH value |
|---|---|---|---|
| ARMv4 and below | not supported | n/a | n/a |
| ARMv5 | supported | GOARM=5 | GOARCH=arm |
| ARMv6 | supported | GOARM=6 | GOARCH=arm |
| ARMv7 | supported | GOARM=7 | GOARCH=arm |
| ARMv8 | supported | n/a | GOARCH=arm64 |
Picking the wrong value results in:
$ ./lpsh-arm
Illegal instruction
Comparing the arm6 and arm7 compilations with diff -y --suppress-common-lines <(xxd lpsh-arm6) <(xxd lpsh-arm7) - the files are unsurprisingly different:
- a great read by DHH on The benefit of seniority ought to be bandwidth
- “There’s nothing more dangerous than excess managerial bandwidth. This is how you cultivate constant churning of plans and processes.”
- “hire managers who’d rather be building”
- moonlighting manager
- Cal Newport - On Slow Writing
- Barkclay Crenshaw 2024 tour dates!!
- I am teaching my elementary school children coding… but not all of them are excited about it. Wondering whether an intro to Pixel Art would be useful for the 7yo who does not want to program in C at the moment: Make Your Own Pixel Art by Jennifer Dawe and Matthew Humphries -
