started to think every passage with more than continuous three paras with solely few words or chars as slop articles from gpt. commonly in addition to phrase "it is..., but..." and frequent use of subjective pronouns "i would."

supporting asymmetric and heterogeneous multiprocessing unit can never be a personal heroism tale.

Girls do not ship with datasheets or TRMs. Unlike a processor, you shouldn't try to reset her if the initial handshake fails. You know every timing constraint, but you never know when to talk to her. Unlike firmware, you can’t patch your awkwardness and retry.

What exactly is being protected, by staying still, that is worth more than what's being lost? He doesn't have an answer. Neither do they. And so the rain falls on the transparent umbrella, and everyone stands very close, and nobody speaks.

Interrupts are asynchronous. Communications are typed data flows.

github.com/orgs/community… I know someone is exploiting advanced models for various purposes, but this couldn't even take up 1%. We don't want to pay an extra $10 for Copilot "castrated" models, in addition to the $20 Cursor, Claude, or Codex.

Sorry for disturbing but have engineers in ST checked the headers of cmsis for N6 and MP2? Pic 1. In MP2xx A35 headers, all of 40 headers omitted a slash for Doxygen comments. Pic 2 and 3. In MP21x and N6 M33 headers, the bitmask operation only had right parentheses.

Submitted a PR for ST for complementing left parenthesis, identified when, after the script parsing, the header panicked: github.com/STMicroelectro…. It could be my first PR related to C code.

The life of a domestic 12 grader is literally not a normal one that one could withstand. Just a figure: less than two months, 16 mock papers in each subject, as well as the same amount of section practice and other mock activities. Every day, a 90-minute paper on each subject.

And the initial inspiration on working on this was a tough pathfinding to a bookstore in Shanghai near SJTU. It reminded me on the experience spending 30 minutes finding ARTEASG in a Intime Mall with only one entry to Basement I.

This is what I started to plan three months ago, and started to write code two months ago. Learning bare-metal firmware on Rust, or mobile app via Tauri. Though the current effect was solely localization and navigation without tested pipeline on access control, it's complete.

200 days past, when I was supposed to recover, finding myself still unable to smile, to greet, or to connect. Not daring to look at the past, yet fearing to face the future, only isolation at present, locking myself in bits and qubits.

I recently opened my first PR to esp-hal. Switching from user to contributor is definitely a cool experience! github.com/esp-rs/esp-hal…

I successfully generated a correct PWM signal for the SG90 using bare-metal Rust-written code on an ESP32C3. It's better to have a prompt to configure those parameters rather than exporting a `config` API that says nothing about the configuration mandated, but overall, it's good.
