"[Computer science] is not really about computers -- and it's not about computers in the same sense that physics is not really about particle accelerators, and biology is not about microscopes and Petri dishes...and geometry isn't really about using surveying instruments. Now the reason that we think computer science is about computers is pretty much the same reason that the Egyptians thought geometry was about surveying instruments: when some field is just getting started and you don't really understand it very well, it's very easy to confuse the essence of what you're doing with the tools that you use." - Hal Ableson (author of SICP).

SICP will show you how CS people 'think' about programming problems and teach you your first language (a semi-toy language, useful for instruction) so it's a great first book. I haven't read the Concrete Math book so I can't really comment on it but I'd definitely encourage you to seek out a good algorithms course after that. I think Harvard has some free courses online. Then you'll want to learn a very high level language like Python for general applications. After that, what tools you learn will be more specific to what you want to end up doing.

I started out in Zoology and then moved into a MS in CS later in my career. The advice @freemo is giving is solid. Anyone with a decent logical mind can do well at the practice of programming (writing good code, working with other developers, etc) but you'll be limited on the design side without brushing up on your math. If you've made it through Cal2 then you should have a strong enough grounding to pick most of the other stuff up. Discrete math and Linear Algebre would be good courses to look for online as supplements.

SCIP is a very good intro book but TAoCS is extremely dense and you'll most likely miss most of the nuance without the equivalent of an intro to algorithms course.

@hansw@mastodon.social THC is THC, and CBD is CBD, they are no different from one strain to the next.

The reason different strains give different effects is because of the ratio of the canibinoids, specifically the ratio of CBD to THC which is the vast majority of what determines effect.

"head highs" as they are called are plants high in THC and low in CBD, sometimes as low as 0.1%. Body highs or mellow highs (where you want to fall asleep) would be the result of a high CBD content along side a decent amount of THC, a 1:1 ratio of each would give an effect that would make you feel tired and relaxed without much of a head high at all.

CBD only has a psychological effect when along side THC though. While CBD's psychoactive effect is very significant along side THC it has almost no psychoactive properties when on its own. The reason for this is how it acts on the receptors in your brain. THC by itself is whats called an Agonist for CB1 and CB2 receptors. By itself it will equally bind and "activate" these two receptors, thus causing the head high. On the other hand CBD is what is called a Antagonist of CB1 and CB2 receptors, though has a more significant effect on CB1 than it does on CB2, what this means is it **blocks** the effect of THC such that the THC has less of an effect and the diminished effect is more pronounced with its binding on CB1 than on CB2, this means when CBD is present along side THC not only is the overall effect significantly diminished but the binding of THC to the receptors is no longer balanced between CB1 and CB2 and almost all the activation occurs on the CB2 receptors. This is why CBD will alter the effects of THC but not have any effects on its own.

All that said it means when you have an isolation of nearly pure THC with no CBD present not only will you get a head high, but the severity of the high will be significant (so usually a good idea to do a much lower dose.

Wow, that's a nice interface! #SpaceX #LaunchAmerica #NASA

This is a look in the Shuttle's cockpit!

Had an idea, controversial, but what you all think?

project idea : Sniper Week

contents : posts all over the place, open to Fediverse, and tagged with a proper tag (to be decided).

* bio of famous snipers.
* cool arms used
* written materials (I have a German Snipers training manual, WWII vintage)
* photos, links to videos on different places.

And all done in the interest of #History, #Technology and general #Knowledge.

Without attitude. Without offending anyone, hopefully. CW if needed.

Thoughts? Thank you!

>There is clearly reasonable and unreasonable CW requirements

That's because you're a reasonable person but many people aren't. Just like those in the instance you mention.
As it's been said the CW requirements currently running on Qoto serve a practical purpose, no sensibilites in play there.
What I say is that if you protect a particular sensibility you're opening the gate to endless discussions.
It's way more easy to defend a 'no sensibilites protected' policy than discussing why A yes but B not with many 'unreasonable' people or groups.

That said, I'm here to have a good time, not to offend anybody and I'll gladly put a CW if I post controversial content.
