           Since it's hiring season, the first question I ask, after a five minute overview of the team, the responsibilities, and myself: Why do you want to join [COMPANY]?

             I've used a lot of GPT-5 Pro and Opus 4.1 to think deeply about how to make HiFi generation faster or better. Everything it told me, I've already tried.

             Unpopular approach to learning C++ During my MSc, I had a great tutor, who taught me binary auditing and reverse engineering using IDA Pro. He challenged us to understand the assembly code, find ways to exploit it and write the exploit, or implement keygens. Thankful for that!

             Thanks to ChatGPT, most of your CVs look the same and make it much easier to filter.

             Today was a good day. Sonnet 4.5 and installed new GPU. Still waiting for the case to arrive.

             Ok, since I need real feedback to keep working on my CLI app, I’m giving away FREE lifetime licenses to anyone who reposts this tweet.

             If the LinkedIn link on your CV results in a 404 and your linked GitHub profile has no public repos, do you even care?

             It's this season again, I'm going through CVs. If you claim to be detail oriented, but name your CV `Armin_Toepfer_Formatted_Resume (1).docx` then it speaks for itself more than the content. And for Christ's sake, do not send .docx! Only PDF.

             Newest low: I gave Claude Code the compile line to reproduce errors. It executes the line, patches the code and then claims it's done. I ask it to retry, it refuses to run the same command again and wants to check the next file. Gaslighting...

             I'm giving up on code-supernova for now. It also bloats up the context window insanely fast.
