没有人能真正精通C++

译文大多数C++程序员都存在着这样一种心态——“如果我能遵守这些规则，避免炫技、避免犯错，我就可以避免把枪口对准自己的脚。

吊打Python！Mojo语言首探！

译文 Mojo显然是为了提供该用例的默认快速版本，在该版本中，不必通过外部库来快速实现。Mojo的目标不是Python更广泛的用例集：web后端、流程自动化等等，至少在早期不是这样。这可能会在Mojo更完整、拥有更好的第三方库时出现，但这显然不是首要任务。

关注点和热点揭秘！大模型用于企业数据开发详解！

译文本文面向的是产品经理、设计师、工程师和其他读者，并假设他们对LLM如何“在引擎盖下”工作知之甚少或一无所知，但是对学习LLM有关概念却很感兴趣，只是不涉及技术细节。

QLoRa：利用GPU微调大型语言模型

译文文章介绍了QLoRa（Quantized LLMs with Low-Rank Adapters），一种在消费者级别的硬件上微调大型语言模型（LLM）的新方法。QLoRa通过引入4位量化、双重量化和利用nVidia统一内存进行分页，大大减少了微调所需的内存，同时保持了与标准微调相当的性能。文章还提供了如何使用QLoRa微调一个拥有200亿参数的GPT模型的详细步骤，包括硬件和软件的要求，以及如何准
