As I have worked as a teaching assistant for C++, I hoped to start learning Java by comparing it with C++. At first glance, Java code does indeed look very similar to C++. But this is just a surface similarity. The primary and most important reminder is: Despite the similar syntax, C++ and Java are … Read more
In xdb v4, the internal operation pointers are all using 4-byte unsigned int, with the maximum pointer value being 2^32 – 1, which means the maximum supported xdb file size is 4GiB (3.999..GiB). This is more than sufficient for the 40M open-source data, so there have been no issues in practical use until recently when … Read more

While emerging libraries like OkHttp and Jodd-http are indeed user-friendly, they still come with a learning curve in certain situations. Often, we … Read more
The iteration speed of both: Software iterates quickly, while embedded systems have remained largely unchanged for decades. The STM32F103 from decades ago is still usable, and even the more advanced STM32H7 series frameworks are quite similar. The transistor technology has nearly reached its bottleneck, and the analog electronics learned decades ago are still relevant. Embedded … Read more
