jq 的開發狀況

Hacker News 上看到「Jaq – A jq clone focused on correctness, speed, and simplicity (github.com/01mf02)」這篇的時候,倒不是 jaq 本身如何,而是在 id=38465712 裡面提到了 jq 的發展停滯了五年左右,但最近又恢復了:

Well, taking into account that jq development has been halted for 5 years and only recently revived again, it's no wonder that bug reports have been sitting there for that time, both well known and new ones. I bet they'll get up to speed and slowly but surely clear the backlog that has built up all this time.

然後下面有提到 https://github.com/jqlang/jq/issues/2305#issuecomment-1572634869 這個,今年六月的時候開始重整團隊改善 bus factor,加入更多新的 maintainer 進來。

算是個好消息,朝向 community 的方式來發展...


GitHub 上的 fulldecent/system-bus-radio 這個專案可以打破實體隔離限制傳遞資訊:

Some computers are intentionally disconnected from the rest of the world. This includes having their internet, wireless, bluetooth, USB, external file storage and audio capabilities removed. This is called "air gapping". Even in such a situation, this program can transmit radio.

有些電腦因為種種因素而實體隔離 (像是因為安全因素,或是保密因素),於是就有人研究各種方法傳遞資訊。這隻程式利用 system bus 在 Macbook Air 上產生 AM radio 訊號:

And run it on an Apple MacBook Air (13-inch, Early 2015):


Then use a Sony STR-K670P radio receiver with the included antenna and tune it to 1580 kHz on AM.

這方法好硬... 但也證明了可以藉由這種方法傳遞訊息。
