PIO vs BIO
PIO:
- CISC architecture
- Rich set of configurable options with each instruction
- Cycle-counting is easy, allowing for hand-crafted bit-bang waveforms and deterministic response times
- Small instruction memory, shared by all four cores
- Optimized for each core implementing a different function
- Larger logic area
- Lower clock rate, but guaranteed IPC of 1
- Custom tooling, no compiler (afaik)
- Closed source, may be encumbered by at least one patent
BIO:
- RISC architecture
- Primitive operations in each instruction: requires several instructions to match a single PIO instruction
- Cycle counting is harder, but deterministic, real-time performance is facilitated with stallable registers
- ISA extensions for direct inter-core communication with FIFOs
- Larger instruction memory, private to each core
- Optimized for multiple cores collaborating to improve performance; or, each core implementing a different function but at a lower speed
- Smaller logic area
- Higher clock rate, but IPC in the range of 0.2-0.33 (could be improved by using more logic area)
- Leverages standard tooling for RV32E, including compilers, assemblers, macros, debuggers, etc.
- Open source, patent-free

計算兩個角度之間的最小角度差（Delta Angle）
((angleNow - anglePrevious) + 3*PI)%(2*PI) - PI
計算兩個角度之間的最小角度差（Delta Angle），並處理了角度環繞（Angle Wrapping）的問題。
以下是它的運作邏輯：
相減：計算當前角度與前一次角度的差值。
位移 (+ 3 * Math.PI)：將差值往正向偏移，確保後續取餘數時處理的是正數空間。
取模 (% 2 * Math.PI)：將角度限制在到 0 to 2*PI的範圍內。
修正回正負區間 (- Math.PI)：將範圍平移回 -PI 到 PI 之間。
結果：
它會回傳一個介於（-180°）到 （180°）之間的數值。
這在處理旋轉邏輯（例如角色轉向或相機追蹤）時非常重要，能確保物體會往最短的路徑轉動，而不是繞一大圈。

Joint Comprehensive Plan of Action
🌐Joint Comprehensive Plan of Action
Under the JCPOA, Iran agreed to constrain its nuclear program by limiting fuel cycle activities that could lead to the production of weapons-grade uranium or plutonium. The JCPOA restricted the number and type of centrifuges in operation, the level of uranium enrichment, and the size of Iran's enriched uranium stockpile. Key facilities at Fordow, Natanz and Arak were repurposed for civilian uses such as medical and industrial research. Iran agreed to accept more intrusive IAEA monitoring measures of its fuel-cycle related activities. In exchange for complying with these restrictions, Iran received relief from nuclear-related sanctions imposed by the United Nations, the EU, and the United States, but many U.S. sanctions unrelated to the nuclear issue—targeting Iran's missile program, support for militant groups, and human rights record—remained in place, limiting the economic effect of sanctions relief. The agreement also set a timetable to lift the UN arms embargo, contingent on Iran's continued compliance with civilian nuclear commitments.
The agreement took effect on 20 January 2016. It was criticized and opposed by Israel, Saudi Arabia, Iranian principlists, and some in the United States.
The United States withdrew from the pact in 2018, imposing sanctions under its maximum pressure campaign. In a symbolic response, members of Iran's Islamic Consultative Assembly burned the text of JCPOA in the Assembly.The sanctions applied to all countries and companies doing business with Iran and cut it off from the international financial system, rendering the nuclear deal's economic provisions null.On 18 October 2025, in the aftermath of the Twelve-Day War, Iran officially announced the termination of the agreement after 10 years.

Lab-On-a-Chip Grippers Could Handle Human Cells Researchers design shape-memory cages to grab cells and organoids
Now, researchers have developed a lab-on-chip that adds a new feature to these systems: low-power grippers that can hold cells or tiny organ models called organoids in place. The CMOS-compatible lab-on-a-chip features shape-memory grippers and chemical sensors for detecting molecules such as neurotransmitters. The micro-cage array was presented in San Francisco on 18 February at the IEEE International Solid State Circuits Conference.

Spec-Driven Development
🎬Coding is dead. Long live the software engineer.
💾Programming as Theory Building
🎤Programming as Theory Building
🌐Understanding Spec-Driven-Development: Kiro, spec-kit, and Tessl
One workflow to fit all sizes? Kiro and spec-kit provide one opinionated workflow each, but I’m quite sure that neither of them is suitable for the majority of real life coding problems. In particular, it’s not quite clear to me how they would cater to enough different problem sizes to be generally applicable.
When I asked Kiro to fix a small bug (it was the same one I used in the past to try Codex), it quickly became clear that the workflow was like using a sledgehammer to crack a nut. The requirements document turned this small bug into 4 “user stories” with a total of 16 acceptance criteria, including gems like “User story: As a developer, I want the transformation function to handle edge cases gracefully, so that the system remains robust when new category formats are introduced.”
I had a similar challenge when I used spec-kit, I wasn’t quite sure what size of problem to use it for. Available tutorials are usually based on creating an application from scratch, because that’s easiest for a tutorial. One of the use cases I ended up trying was a feature that would be a 3-5 point story on one of my past teams. The feature depended on a lot of code that was already there, it was supposed to build an overview modal that summarised a bunch of data from an existing dashboard. With the amount of steps spec-kit took, and the amount of markdown files it created for me to review, this again felt like overkill for the size of the problem. It was a bigger problem than the one I used with Kiro, but also a much more elaborate workflow. I never even finished the full implementation, but I think in the same time it took me to run and review the spec-kit results I could have implemented the feature with “plain” AI-assisted coding, and I would have felt much more in control.
An effective SDD tool would at the very least have to provide flexibility for a few different core workflows, for different sizes and types of changes.

BNO085
The BNO085 by the motion sensing experts at Hillcrest Laboratories takes the familiar 3-axis accelerometers, gyroscopes, and magnetometers and packages then alongside an Arm Cortex M0 processor running Hillcrest's SH-2 firmware that handles the work of reading the sensors, fusing the measurements into data that you can use directly, and packaging that data and delivering it to you. If the name and description of the BNO085 sounds strikingly similar to those of the BNO055 by Bosch Sensortec, there is a good reason why: they're the same thing, but also they're not. Thanks to a unique agreement between Bosch and Hillcrest, the BNO085 uses the same hardware as the BNO055 but very different firmware running on it.
