SWE in Machine Learning GPU Systems Software at Google.

In my free time, lately I am attempting building a new programming language.

My interests include Linux, C++, operating systems, GPU programming, optimization, multithreading, and Go.
Today #samsung raped my phone. It installed "one ui 2.0" without my consent, without asking me, and they use extortion to force the software onto my phone. #endsoftwarerape

#C++ #performance #optimization. Remember that reducing the number of instructions doesn't matter that much anymore. The type of instructions and memory bandwidth matters much more! Zen 5 can execute around 2500 additions in the time it takes to do 1 non-cached load from main memory.

Tip for code #optimization in low level languages like #c and C++ #cpp (or #rust):

If you need to do multiple reads (R) and writes(W), then you'll usually find that RRRRWWWW is faster than RWRWRWRW.

Bought an espresso machine and coffee grinder... but despite what Amazon's #ai says, the Cuisinart DBM-8P1 cannot grind #coffee into #espresso grinds.

Ordered a Shardor grinder, which is a brand I've never heard of... but it has a setting for espresso, so fingers crossed...

Meta's false use of the term open source to describe Llamma needs to be remedied with a lawsuit. #opensource #meta #ai

C++ is the most modern programming language, but suffers from poor designs in tooling and dependency management by GNU, Apple, and Microsoft. Docker makes this much more manageable for Linux, but it's a band-aid for bad tools, not a true solution to the root cause. #docker #c++
