Critical Path != Critical Section

I always get the concepts “critical path” and “critical section” confused.

The “critical section” is the part in your algorithm which you must hold a lock for; whereas the “critical path” is an idea from hardware design which relates to the time taken for the longest combinatorial logic that needs to be processed during a clock cycle, thus limiting the frequency you can run your clock at.

Although the terminology “critical path” came from hardware, the same terminology is used in software. ChatGPT has a fairly good write-up on the two uses of the term “critical path”.

I learned a little more about this in Introduction to VHDL for FPGA and ASIC design.

Whatever happened to the girl who played the cello for Nirvana Unplugged?

ChatGPT:

The girl who played the cello during Nirvana’s MTV Unplugged performance in 1993 was Lori Goldston. Lori Goldston is a talented cellist who has had a successful career as a musician and composer. After her appearance with Nirvana, she continued to collaborate with various artists and bands, both as a performer and a recording artist.

Following the Nirvana Unplugged performance, Lori Goldston went on to work with musicians such as David Byrne, Cat Power, and Earth. She has also released solo albums and composed music for films and dance performances. In addition to her work as a cellist, Goldston is known for her improvisational and experimental approach to music.

Lori Goldston’s contribution to the Nirvana Unplugged performance, particularly her cello arrangement for the song “Something in the Way,” received critical acclaim and is still celebrated by fans of the band. Her performance added a unique and haunting element to the already iconic concert.

As of my knowledge cutoff in September 2021, Lori Goldston was actively involved in the music industry, and she continues to perform, compose, and collaborate with various artists. However, for the most up-to-date information on her current activities, it’s recommended to check reliable sources or her official website.

Intuitionism

Recently I read about Intuitionism and I can tell you unreservedly that I do not believe in it. I believe that objective things can exist independent of human minds and the most salient example I could give is in your computers. In your computer you can calculate 1 + 1 = 2 and you can do so quite independently of a human mind. 1 + 1 = 2 is an objective truth which can easily be modelled in a machine. Certainly mathematics can *also* be the result of constructive mental activity in human minds, but it is not limited to that. Also it might be interesting to note that machines will be able to find objective mathematical truths which are beyond the capacity of a human mind alone, in fact I’m quite sure that will have been done already (if you can think of an example feel free to let me know!).
