As we try to refactor the code to work this way, one question comes up — what should we do when there's an error (such as an invalid number of sides)? A number of utilities that I use seem to have a common convention for reporting errors (i.e. printing the name of the program before printing the actual error message), but what actually is this convention? It turns out that this originally came from the GNU coding standards! I did not know this until this experiment, and the fact that I didn't doesn't reflect well on the success of the mission of the GNU project.
AI发展提速对半导体的拉动力正在从AI芯片延伸到更广阔的领域，近日被动元器件迎来更加确定的全面涨价信号——日本被动元器件大厂村田已就MLCC（片式多层陶瓷电容）涨价事项启动了内部讨论。此前，受原材料涨价、AI及汽车需求拉动等因素影响，2025年下半年至2026年2月，包括MLCC、电阻、电感、钽电容、磁珠等产品在内的多种被动元器件，已现多轮次涨价，价格涨幅普遍在5%至30%。“事实上，高涨的需求叠加原材料涨价，被动元器件涨价行情才刚刚开启。”有分销商人士表示，村田对MLCC开启涨价，不仅显示出AI动力强劲、高端被动元器件景气度的确定性，还将挤压MLCC低端产能，从而带动被动元器件进入全面涨价阶段。（上证报）。业内人士推荐新收录的资料作为进阶阅读
