weekends are for leisure

TL;DR: I’m learning Rust, creating a sharding StatsD proxy as a learning project, and am creating YouTube videos of the process. See Relaxing With Code.

I’ve wanted to “factory reset” my old Android phones for years but hadn’t found a good way of exporting text messages including the embedded images and videos. Some solutions involve rooting your phone, and I didn’t want to do that. Nor did I want to use an app that copied to Gmail or the cloud. And I wanted to know exactly what the app’s code was doing. So I found the MessageBackup repo on GitHub and used it as a starting point.

I recently purchased a Dell Mini 1012 on Ebay and wanted to ensure it had the latest BIOS update from 2011. Dell’s website provides an exe, but I rarely boot into Windows. I managed to find a Linux-only workaround.

What I Tried

It was a bit of a journey. If you want the TL;DR, go to the next section.

1. According to Ubuntu’s Dell BIOS page you can flash the BIOS using FreeDOS and a USB stick. Sounds promising.
2. On a Linux machine I downloaded the “Lite USB” version of FreeDOS
3. Flashed it to a USB stick with a command like this: dd if=./FD12LITE.img of=/dev/sde bs=4M conv=fsync status=progress
4. Mounted the filesystem with a command like this: mount /dev/sde1 /mnt/other
5. Tried to copy the BIOS exe into /mnt/other but there was no space on the filesystem. The FreeDOS image makes a very small FAT16 filesystem on the device
6. I then tried to resize the filesystem (to give me enough free space for the BIOS exe) using gparted but gparted wasn’t able to resize
7. I considered doing the same with the CDROM image, but really didn’t want to resize any partitions at all …
8. Then I realized I could likely gain free space by deleting files from the FULL version of FreeDOS
9. So I downloaded the “Full USB” version of FreeDOS instead
10. Wrote it to the USB stick (same as above)
11. Mounted the filesystem
12. Explored the contents and ultimately decided to delete the packages/games folder since it was large
13. Copied the BIOS exe to /mnt/other
14. Unmounted the filesystem
15. Booted with it
16. Skipped FreeDOS installation to go back to DOS. Believe it was second menu option
17. Tried to run the BIOS exe. Grr, it said it can only be run from within Windows.
18. Uhhhhh
19. I checked the notes associated with the BIOS exe on Dell’s website and saw this: “This file contains a compressed (or zipped) set of files. Download the file to a folder on your hard drive, and then run (double-click) it to unzip the set of files”.
20. I thought to my self: Ok, it’s a self-extracting exe. That must be a pretty standard format. I wonder if the unzip command on Linux can extract it?
21. Turns out unzip CAN extract a self-extracting exe. Yes!
22. I remounted the USB filesystem to /mnt/other, navigated to it within a terminal
23. Ran: unzip ./R30BLABLA.exe
24. It extracted the contents within the USB stick
25. Woo!
26. umount /mnt/other
27. Reboot laptop
28. Skip FreeDOS install, menu option 2
29. Run exe that isn’t prefixed with “win”
30. Watch while the BIOS is flashed

What Actually Worked

Condensed steps from my journey above.

This post is about how and why I pieced together my own motion-detection and encoding system. I wanted to produce smooth HD videos whenever motion was detected. Find the code here.

Note: I plan to add videos and stills to make this more than a wall of text, but wanted to get it out before the holidays.

Raspberry Pi computers are powerful despite being small. Did you know the raspivid program can capture 1080p at 30fps without breaking a sweat? Given that, I figured it should be possible to layer on motion detection without impacting the HD video quality too greatly. But like many things, it’s harder than you might think.

Queued up some Koufax on my morning walk. It had been a while. Sometimes I forget how effective horns can be. Move Out, Move On.

Amanda Nguyen is truly inspiring. That’s not something I say lightly.

• She formulated an effective strategy for getting important bills passed unanimously.
• She passed legislation by “taking our egos and shoving [them] somewhere”. Oh and compromise and respect. Yes!
• She fought to fix the broken criminal justice system as it pertains to sexual assault, and rolled that experience into Rise Justice Labs.
• Oh, and she’s training to become an astronaut.
• The ZeroUSA campaign wants to ensure that politicians will be safe in voting for gun violence prevention legislation. Founded by someone who doesn’t want to lose his second sister to gun violence. Damn, that’s heart-breaking.
• “This is a time of frustration, of political tribalism, and of waning faith in our democracy. And I don’t think there’s ever been a more vital moment in our history for people to understand that they hold the power.”
• “I needed to work with people from all walks of life and people I didn’t agree with in order to pass laws.”
• “In order for a healthy democracy to function, it’s citizens need to be able to hash things out. And we, I think, in this moment of extreme toxic political tribalism, have lost that.”

Given that I have a lot less time these days, and that my brain is being taxed by a recent job change, I’ve been on the lookout for shorter, less attention-demanding podcasts. Enter AFK from Changelog. Episodes are less than 30 minutes, and showcase “the human side of creative work”.

Especially check out AFK with Suz Hinton. They touch on burnout, and the importance of asking for help. It’s not a sign of failure.

I started a new job recently and my on-boarding mentor told me I was bringing lots of value to pull request reviews despite being the new guy. This caused me to pause and reflect on how I approach code reviews, what I might be doing differently from others, why I do it and where my habits came from.

Perhaps the best way to describe my approach is that I think of code reviews as an asynchronous pair coding session:
