By not having a Dual-Culturalist, like me, on the team.
When the twin towers in Kuala Lumpur was being built, I was friends with some guys on the project management team and some guys at Tyco (electrical subcontractor);
"We work hard. Easily 10 hours a day... but we can't keep up with the Japanese [one of the towers]...12 hours a day, six days a week, and let's not mention the Koreans, 14 hours a day, 7 days a week, and 1 day off per month."
There was a race to completion.

An interesting clash of Western and Eastern work cultures.
But I wonder, how did this fall through the cracks?
Tiny C Compiler runs in #WebAssembly but it's missing C Header Files ... Let's add the ROM FS Filesystem from Apache #NuttX RTOS ... With a little help from #ZigLang Compiler
It's alive! Milk-V Duo S with #RISCV SG2000 ... USB UART Dongle must be CP2102, it doesn't like CH340G 😬

@Lup Yuen Lee 李立源 you know, I've been considering something like this with a Kindle 2nd generation which didn't come with WIFI but was one that used the 3G network. I've been thinking of ways to mate it with one of the very smallest #ESP32 on the market, to make that particular generation of Kindle Ereader, WIFI capable.
Because of USB Network hacks, the Kindle 2nd generation runs Linux on a MIPS processor and the front end is mostly Java code I think. Anyway, I'm going to plan carefully before I even attempt it but it would be a sweet little hack, I think.
