I found reading Linux source more useful than learning about xv6 because I run Linux and reading through source felt immediately useful. I.e, tracing exactly how a real process I work with everyday gets created.

Can you explain this O(n2) vs O(n) significance better?

Have you considered EBPF filter that looks for 'Mozilla/5.0 (compatible; crawler)' and drops packets from that IP for 1 hr where it just straight drops packets. I.e, this is probably best way to handle bots, don't even reply so they have to timeout which usually is a few seconds.
good sick of all the cheap Chinese products that break in a week and have to order another. Even the clothing seems to fade and be useless in 6 months.

from my understanding RISC-V chips are slower and more expensive and less optimized compilers, so why in the world would an end user use one?

Can what you explain what the significance of the US 10 year yield going up is?
Book is 10 years old, isn't it outdated?
Wonder what percent of illegals are criminals (other than being illegals). My guess is 10 percent (but no idea Trump probably thinks 80 percent) and is why most people in California consider illegal immigration as acceptable.
interoperability with subpar user experience is just an excuse for poor engineering or low resources. I.e, my x-wifi-network card doesn't work in Linux. No one is spending time making it work / too many devices to test properly. It is the manufacturers responsibility to make it work with linux and they don't care so there are a few people that make it work and write generic drivers that may or may not be optimized to the specific manufature. Same story for all " interoperability subpar user experience"
Unfortunately many of these scientist stopped doing science and became activist.

$1 for 1000 pages seems high to me. Doing a google search

Rent and Reserve NVIDIA A100 GPU 80GB - Pricing Starts from $1.35/hour

I just don't know if in 1 hour and with a A100 I can process more than a 1000 pages. I'm guessing yes.

Don't really need a study for something you can figure out fairly easily on your own. I tried to smoke and program probably 3 times and results were always the same. Significantly less productive. Started working on tasks not aligned with larger goal. Had many ideas that seemed amazing at the time and later found out to be dumb. In that sense it is creative enhancement in that you consider more idea, but just in general most ideas are dumb. Difficult to stay focused on the most important task and makes me wonder more. Loss of focus.

The real question is: How do I use cannabis correctly? What can it actually do for you?

From my experience smoking once every 2 months has net benefit... It cannot help you program but it can help you higher level ideas related to programming. It can answer the why better than it can answer the how. It can be a reset and motivation and prevent you from burn out even if you are working more than 60 hrs a week. But it is dangerous in that you want to get the relief constantly, so from my experience once every 2 months is fine.
