A quick search reveals several other serious vulnerabilities in Tenda routers that could grant administrator privileges. Therefore, I tend to believe this is due to the company's incompetence and lack of technical skill rather than malicious intent—but it's still a reason to avoid using Tenda products. There's a reason why Tenda's market share is far lower than TP-Link's.
There are many open-source software developers whose backgrounds we don't know much about, such as Russell King, who implemented the 32-bit ARM port of Linux. He used the magic number 0x016F2818 (24061976 in decimal) without explanation, which I guess is his birthday, but I can't verify it since he hasn't disclosed his birthday anywhere.
Because Türkiye is a widely recognized sovereign state, while Taiwan (or more formally, the Republic of China) is not. Taiwan is also not a member of ISO.
It's best to avoid using std::wstring and other wchar_t-related facilities, as they are highly non-portable across different platforms. If you need to interact with the Win32 API, use char16_t and std::u16string, so that anyone knows it contains a UTF-16 encoded string and knows how to use and process it.
In ancient China, the imperial year designations were usually changed in the second year following the coronation of a new emperor, thus preventing the occurrence of two imperial year designations in the same year. Japan seems to have chosen to change the imperial year designation in the same year because of the faster flow of information in modern times. I still think it would be more convenient to change it the second year.
I've recently been doing something similar: I have a UbiSurfer 9, a netbook using an S3C2416 chip as its CPU, running the ARMv5 instruction set, and with 128MB of DDR2 memory. Its original operating system is WinCE 6.0, and I'm trying to run Linux on it. The good news is that Debian still maintains the armel architecture, so we potentially have a large number of userspace programs available. The bad news is there's no suitable kernel and bootloader. Fortunately, a friend helped me write a bootloader and modified the kernel source code to make it work. Running a Debian system is possible, but quite slow, so I created a minimal system with only Busybox[1], and it works perfectly.
