User provided content (post using custom emojis) caused havoc when processing (doesn’t matter if on server or on client). This is lack of sanitization of user-provided-data.

100%. Always act as though user provided content is malicious.

JavaScript (TypeScript) has access to cookies (and thus JWT). This should be handled by web browser, not JS.

Uh… what? JavaScript is a client-side language (unless you’re using NodeJS, which Lemmy is not). Which means JavaScript runs in the browser. And that JavaScript has access to cookies, that’s just a basic part of how web browsers work. Lemmy can’t do anything to prevent that.

How the attacker got those JWTs? JavaScript sent them to him? Web browser sent them to him when requesting resources form his server? This is lack of site isolation, one web page should not have access to other domains, requesting data form them or sending data to them.

Again, Lemmy can’t do anything about that. Once there’s a vulnerability that allows an attacker to inject arbitrary JS into the site, Lemmy can’t do anything to prevent that JS from making requests.

Then, if they want to administer something, they should log-in using separate username + password into separate log-in form and display completely different web page

On the backend you’d still have a single system which kind of defeats the purpose. Unless you’re proposing a completely independent backend? Because that would be a massive PITA to build and would drastically increase the system’s complexity and reduce maintainability.

I’ll still use Reddit for cat pictures and stuff like that but this feels more like a community to me than Reddit ever did.

Java is the top, C# is the bottom. The Java language designers consider unsigned integers harmful (and this). They’re basically saying “You could hurt yourself with this so we’re taking it away.” I find that patronizing and disrespectful. On the other hand C# and Go tell you, “Yo bro, doing pointer math and direct memory manipulation is not safe, but I’m not gonna stop you.”

This is how I feel about Java vs Go/C#/etc

What about a general programming news community, kind of like Hacker News?
