Hard drive failure analysis – the Backblaze experience

backblaze.com marks 13 years of collecting Hard Drive Stats data. Statistics such as these provide folks who may not be keeping such detailed records to have a statistical approximation as to how and when their own hard drives might develop faults.

As of the end of 2025, Backblaze was monitoring 341,664 drives used to store data. For our evaluation, we removed from consideration 4,013 boot drives and 459 hard drives, as they did not meet the criteria to be included. Removing these drives leaves us with 337,192 hard drives to analyze.

See Backblaze’s detailed report on their disk inventory in the post here.

NEW LEARN GUIDE: Tiny Wiki for CircuitPython #CircuitPython #AdafruitLearningSystem @Adafruit

Tiny Wiki is a small webserver that runs on a microcontroller and hosts a minimal Wiki system backed by markdown files. It was originally created by Kevin McAleer for Micropython devices. You can create and edit pages, linking them together to form a Wiki structure. This guide features a CircuitPython port of the Tiny Wiki project. It is built using the CircuitPython HTTPServer and TemplateEngine libraries. It was designed for the Adafruit Fruit Jam, but could be adapted for other CircuitPython devices with access to WiFi and a microSD card.

Making an STM32G431 analogue TV transmitter

Kris Slyka has a bit of an obsession with vintage analogue video cameras.

A few weeks ago I felt like it was finally time to take the next step and get myself one of those “televisions” I had heard so much about. Stop feeding those pristine analogue signals into a digital capture card and instead enjoy them fully analogue, end to end, crt to crt.

Turns out that one of the reasons this TV was so cheap was because it doesn’t have any video input besides an antenna. And it’s black and white. Both of which are deeply disappointing to gamers. And since analogue video broadcasts around here have stopped like a decade ago I couldn’t even enjoy our high quality domestic TV programming, let alone connect any of my weird cameras.

So, there’s two options here, basically: Either, mod the TV for composite video input (not too hard) or just get an RF modulator (easy).

After realizing that broadcast television uses negative modulation I was able to hack together a little inverter and amplifier circuit, hook up one of my cameras and get beautifully bad looking low latency video, no computers involved! Easy!

See how Kris performed this electronic magic in the post here.

Daisy Gatson Bates Day Black History Month 2026 #BlackHistoryMonth #DaisyGatsonBatesDay

Daisy Lee Gatson Bates was a civil rights activist who played an integral role in the integration of Arkansas schools. She was a mentor to the Little Rock Nine, she and her husband also published the Arkansas State Press a revolutionary newspaper that dealt with civil rights and other issues in the black community.

From Arkansas PBS:

Daisy Gatson Bates was a trailblazer in the Civil Rights Movement and played an integral role in the integration of Little Rock Central High School in 1957. She served as the president of the Arkansas Chapter of the NAACP. Her work made her a household name, and, on Feb. 19, 2001, the state of Arkansas declared that the third Monday of February would be Daisy Bates Day. This year, we celebrate Daisy Bates Day on Monday, Feb. 17.
