The Courier and the truck

The Courier and the truck; complement and substitute Although people say “this time is different”, there is something in common. In the ancient ancient times, if you needed a parcel moved across the country, you hired a body. The good courier had good strength to carry the parcels, strong legs, deep lungs, and a tolerance for going without (too much) rest. Those were the metrics. Speed was a property of the person, so you paid for the person who had the most of it. ...

The overthinking of LLM

I asked Deepseek to draw the Schlegel diagram of a hexahedron — should be a very simple task right? Just 2 squares and link up their vertices. And yet I noticed something interesting: it tends to overthink and end up outputting nonsense answers when DeepThink is on (which is supposed to be more powerful and “clever”), but getting the task done correctly when DeepThink is off.

Why do I hate using chatGPT to replace search engines

My pc is overheated how do i cool it down because it is my life1 Someone said that chatGPT will replace Google. Some kids/ early teenagers do often ask chatGPT for things that could have been found by Googling. I really hate the idea of replacing search engines by chatGPT.

When we were kids and learnt how to use search engines, we acquired the skills of capturing important parts of the questions in our minds and turn them into keywords. Bashing questions like “my hard disk is full how can I get more space” usually get worse results than things like “hard disk space full solutions” as their counterparts. ...
