Youngsters find it hard to believe, but before Apple introduced the first cell phone, you had to carry one of these bad boys with you if you wanted to stay in touch with friends

Pundits: social media is an existential threat to the youth and to democracy itself

Government: ok we're gonna take away TikTok

Pundits: nooooooo I was using that

C pro trick! Let's say you have code like this, and you want to comment out a block of code - let's say, lines 5 to 7 - with some nested comments. A pain, right?

Well, not anymore -- not with my patented POWER COMMENT technique!

Security product vendor: you've come to the right place, we have a wide selection of stuffed birds

One of my favorite things is asking LLMs "what's wrong with <this>" when nothing is wrong with <this>. Works with code, circuit schematics, and so on.

You usually get a wall of *really* convincing text, and I imagine some poor student trying to make sense of this.

A 15-minute intro to resin casting: https://lcamtuf.substack.com/p/a-15-minute-intro-to-resin-casting

I sometimes get asked why I still wear an analog wristwatch. It's true that I don't need it. But it is a symbol of a certain level of sophistication and class.

You can use an if () statement to see if the feature is supported by your compiler.

@dalias OK, you advance to level 2

Without running the code, guess the result

I have a big announcement to make, we're coming out of stealth
