Things you can do with a debugger but not with print debugging

news.ycombinator.com Unknown 2025-10-01 02:22:54

Things you can do with a debugger but not with print debugging People do or do not use debuggers for a variety of reasons. For one thing, they are hard to setup in many codebases. Second, you can’t use them when your application is running on remote environments (such as kuberenetes). So, anecdotally, I have seen way more people using Print/ log.Debug compared to a debugger. Which is a shame, because while debug logging is convenient at times, debuggers can do some things which you can’t easil

gizmodo.com Riley Gutiérrez Mcdermid 2025-10-19 10:06:55

As investments in artificial intelligence continue to soar, some analysts are raising alarms about a looming bubble that could burst and trigger broader market declines. Others, however, say they’ve never been so sure that it is a growing opportunity. So who is right? Well, on Wall Street, there’s a pick-your-flavor opinion for whatever it is you want to back, so we can’t determine that. But we can show you what each side is thinking.

In Brief When Amazon hired the founders of AI startup Adept last year, it was one of the first examples of what became known as a reverse acqui-hire — a deal where a large company hires key startup team members and licenses its technology, rather than acquiring the startup outright.

Why Go Rocks for Building a Lua Interpreter

By Roxy Light I recently needed to build a custom Lua interpreter in Go. The exact reasons aren’t important for this blog post, but neither the reference implementation — which I will be referring to as “C Lua” throughout this article — nor the other open source Go Lua intepreters I could find were a good fit for my needs.
