Yet another dev thinking he's a cybersecurity expert 💀
https://www.reddit.com/r/programming/comments/1mb9beb/yet_another_dev_thinking_hes_a_cybersecurity/

<!-- SC_OFF -->So I decided to make an "antivirus" for Node.js. It checks uploaded files, marks them as clean / suspicious / malicious, and even lets you plug in YARA rules. Basically: "Yo bro, your ZIP file smells like malware, I ain't saving that." Is this useful, funny, or just plain cringe? I can’t tell anymore. <!-- SC_ON --> submitted by /u/Extension-Count-2412 (https://www.reddit.com/user/Extension-Count-2412)

Here comes the sun

<!-- SC_OFF -->“Write crates, not programs” is a mantra my students are probably tired of hearing, but it's something I think many programmers would do well to bear in mind. Instead of being a Colonial gunsmith, in Scott Rosenberg's analogy, hand-crafting every nut and screw, we should instead think about how to contribute trusted, stable components to a global repository of robust software: the universal library of Rust. I have a fairly well-defined process for going about this. Here it is. <!-- SC_ON --> submitted by /u/AlexandraLinnea (https://www.reddit.com/user/AlexandraLinnea)
