Hi, 各位朋友，这是本频道的第 3 期内容。我们开启新的系列—— IT 热点速递。本文选取了 GitHub trending 和 Hacker News 上的热门、有一定普适性的内容，希望对你的工作有所帮助。
1. RenderCV: resume generator for academics and engineers
source: https://github.com/rendercv/rendercv
resume 这里是“简历”的含义，注意发音是 /‘rɛzjuːmeɪ/，近似：REZ-you-may. 它还有“继续”的含义，此时发音 /rɪˈzuːm/ 近似：ri-ZOOM. 为了区分，有时做“简历”意时可以写成 résumé.
简历, 在北美常用 resume 这个单词，而英式、欧洲用 CV (curriculum vitae).
Write your CV or resume as YAML, then run RenderCV by rendercv render John_Doe_CV.yaml, and get a PDF with perfect typography. No template wrestling. No broken layouts. Consistent spacing, every time.
With RenderCV, you can:
- Version-control your CV — it’s just text.
- Focus on content — don’t worry about the formatting.
- Get perfect typography — pixel-perfect alignment and spacing, handled for you.
typography: 排版
wrestling: 有“摔跤”的含义，here means struggling with something difficult, awkward, or frustrating, rather than the sport - “较劲/折磨”。注意发音 /ˈre-sliŋ/, t is silent.
- I spent hours wrestling with the configuration files.
- No more wrestling with CSS layouts.
2. Fabrice Bellard Releases MicroQuickJS

今日 Hack News top1.
MicroQuickJS (aka. MQuickJS) is a Javascript engine targeted at embedded systems. It compiles and runs Javascript programs with as low as 10 kB of RAM. The whole engine requires about 100 kB of ROM (ARM Thumb-2 code) including the C library. The speed is comparable to QuickJS.
引起如此热议的原因有 2 个: JS related; Fabrice Bellard (the developer) related.
(comment 1) This engine restricts JS in all of the ways I wished I could restrict the language back when I was working on JSC. You can’t restrict JS that way on the web because of compatibility. But I totally buy that restricting it this way for embedded systems will result in something that sparks joy.
(comment 2) Well, as Jeff Atwood famously said, “any application that can be written in JavaScript, will eventually be written in JavaScript”. I guess that applies to embedded systems too.
注意这个 buy, 非常 native 的用法。 If you buy an idea or explanation, you believe it, accept it, or find it convincing, 类似中文的 “买账”.
- I buy that.
- Do you really buy this explanation?
- I don’t buy the idea that complexity is unavoidable.
- At first I was skeptical, but now I buy it. (skeptical, 怀疑的)
(comment 2) Fabrice is an absolute legend. Most people would be content with just making QEMU, but this guy makes TinyC and FFmpeg and QuickJS and MicroQuickJS and a bunch of other huge projects. I am envious that I will never anywhere near his level of productivity.
(comment 3) For all the praise he gets here, few seem interested in his methods: writing complete programs, based on robust computer science, with minimal dependencies and tooling.
(comment 4) When I first read the source for his original QuickJS implementation I was amazed to discover he created the entirety of JavaScript in a single xxx thousand line C file (more or less). That was a sort of defining moment in my personal coding; a lot of my websites and apps are now single file source wherever possible/practical.
versatile: “多面手”,常用来形容人或者工具。
be content with: If you are content with something, you are satisfied with it and do not want more or anything different. “满意，知足”。
envious: adj 嫉妒的(动词 envy)
a sort of: If you say a sort of something, you mean a type or kind of it, or something that is like it but not exactly the same. 口语里常用。
- Quill acts as a sort of rich-text playground for web developers.
- The configuration file is a sort of blueprint for building the system.
3. We replaced H.264 streaming with JPEG screenshots (and it worked better)

基于 ChatGPT 摘要，我再重新组织了下重点，希望对你有所启发。
The initial implementation used a modern video pipeline: hardware-accelerated H.264 encoding, WebSockets, and browser-side decoding. On paper, it delivered smooth, high-frame-rate video. In practice, it frequently failed. Many corporate networks aggressively restrict traffic, deprioritize UDP, or block WebRTC-related protocols altogether, leaving only HTTPS traffic on port 443 reliably usable.
企业网络上对网络协议有限制，阻碍了新技术的应用。On paper, In practice 适合用在理想和实际的对比中；aggressively 激进地；deprioritize 使低优先.
In the end, the most reliable solution turned out to be the simplest one: periodically serving JPEG screenshots over plain HTTPS. Despite being more than a decade old, this approach worked consistently across locked-down enterprise networks, degraded gracefully under poor conditions, and required far less infrastructure and client-side complexity.
最简单的方法成为了最可靠的方法。turned out to be 适合用在结论处；periodically 定时地；locked-down, 封锁的, 高度受限的。
The takeaway is not that modern streaming technologies are bad, but that real-world constraints matter more than theoretical elegance. Sometimes, shipping a robust product means choosing boring, well-understood tools — and accepting that older technology can still be the right answer.
方法是为问题服务的。The takeaway is 适合做经验总结；elegance 优雅；ship a product 固定用法。
