Submission + - Chinese robot runs 100m sprint quicker than Usain Bolt's world record (theguardian.com)

fjo3 writes: A robot named Lightning has run the 100m in 9.32 seconds, beating the human world record, China’s state broadcaster has reported.

The humanoid, developed by the Chinese smartphone manufacturer Honor, reached a peak speed of 14.5 metres per second during a test event for the second World Humanoid Robot Games, which began on Saturday. The performance surpassed the 9.58sec men’s 100m world record set by Usain Bolt 17 years ago at the World Athletics Championships in Berlin.

Explain:

It's a Korn Shell script.

Check the readme above for a bit more of an explanation. It's fun. And really challenging, even though there's only 3 words and 3 bits to work with on the virtual machine, a 'Seed'. You combine the words together and see if the calculation computes correctly based on your assumption on a non-deterministic machine. It starts out easy, but it get's difficult quickly. Here's the start. Check the github for the rest: #!/bin/ksh DEBUG=t # expect - test your expectations # # BusFactor1 Inc. # 2017 # License: AGPL set +k tee () { echo -n "$1 " /usr/bin/tee $2 } function tri { # execute the next word if x is 1 x=$(

Thank you for the interesting response. Could you explain a bit more about what you mean by "using for example tree-pattern-matching replacement into a low-level form". What would you be replacing with what?

My goto performance sensitive problem has always been raytracing, so I think that's the next logical project to implement with this tool and see where it goes.

Unfortunately, the editors messed up a bit with the explanation of what sxc is and what it is good for. It's not about compiling your Lisp code to C, it's about writing C code using Lisp. With the S-Expression syntax of sxc, a whole world of macro programming and code generation become possible in a natural matter leading from the using of S-Expression and macros. This, so far, has been uncharted territory, although his type of project is quite popular to implement. It seems that nobody has actually used to it's full potential yet; hence the question.

What do you think that the combination of a high level language for the generation of a low level processing language would provide, if anything over the normal combinations of cc + cpp?
