I really, truly wish HN would moderate and remove comments about a link's medium. Every single post here has at least one person complaining about the layout of the source. Every time. It's exhausting. I hate it. It contributes absolutely nothing, and I don't know if anyone's noticed, but people keep using Twitter! Gasp! If you hate Twitter so much, reach out to the tweet author and ask them to publish elsewhere. If you hate Medium, e-mail the author and ask them to switch platforms. But dear God, can we please stop complaining about it in HN comments? Either read it or don't.
I wouldn't be surprised by any of this, but the reddit post reads too... reddit-y, I guess? I mean, I could easily write a post like that without actually doing anything. Where's the proof? I want to see these analytics payloads. I want to see how they disassembled the app. So far, though, there's not a lot of proof, just some statements about analytics data and "I'm a nerd who figures out how apps work for a job".
I'd argue that if you are neither willing nor able to learn nginx's config file format, you should not be configuring nginx. The default config has example blocks with comments anyway. If that's not enough, nginx maintains current documentation. But if you're configuring a web server (or anything, for that matter), you should take some time to learn how to configure it.
I wish people would stop thinking of S3 as a filesystem because it isn't, and in ways that can cause serious issues. I can't tell you how many questions I get from devs asking "how do I rename a file in S3?" You can't. They're not files. It's not a filesystem. The folders you see on the web interface are just sugar, but if you have only a superficial knowledge of S3, you might be tricked into believing it behaves like a filesystem.
S3 is an eventually-consistent object store. We need to treat it as such.
Please just stop.
