💡 Did you know that you can craft URLs that bypass X/Twitter's URL shortener (t[.]co) and domain deny list?

For instance, try sharing x.com/login?redire... in a tweet and clicking the link; you will ultimately be redirected to ddosecrets.com (which is banned by X) without ever traversing t[.]co!

FWIW, here is a snapshot of a slide from my introductory course:

This is the kind of stuff that "optics" conjures up in my mind when I chance upon it in a news article. Nothing else. 🤷

Initialising a #CORS middleware has been steadily getting faster and less memory-hungry in recent versions of github.com/jub0bs/cors, as shown by this chart (lower is better). 😇 #golang

Go's logo may strike you as uninspired and unremarkable. I'm guessing that the manga-style speed lines are meant to convey that the language is intended for "programming at scale". Right?

It turns out that rs/cors (Go's most popular CORS middleware library) allocates a lot of memory in response to some malicious unauthenticated requests. 😬

Here is a Go challenge for you! 🤓
Without modifying my package named "puzzler", can you create, in the main function, a variable of (non-exported) type puzzler.config? Playground: https://go.dev/play/p/hSSRfbZbjKK
I'll post a solution tomorrow. 😉

NaNs and maps don't mix well, but Go 1.21's upcoming 'clear' builtin function will allow us to properly delete all keys from a map (including keys that are not reflexive for equality). This is likely to prove particularly useful in generic code.
