foobiekr··on Tesla Optimus Bots Were Remotely Operated at Cybercab Event
It is clear they were in terms of starting off. But it was on a closed set - an undergrad could have coded what they showed.

They didn’t say the extent of the control and the event was engineered to lead people to conclude human involvement was minor.

The problem is it was presented in the most manipulative and deceptive way possible.

so so so so so so so so so much this. I have tried to make prolog a part of various systems on and off for two decades and the ergonomics and basic practical shit like this is why it never works.

the answer is always: do a lot of manual stuff that the language should do for you. I can, but I can't get a team to.

foobiekr··on Psilocybin bests SSRI for major depression in first long-term comparison
Never tried it. Seems like it's vaguely hard to consume safely since it is tied to shaman woo culture overseas. Supposedly there are sessions in the bay area, but I'm not cool enough to know people who know about them, or for that matter the other things I'd like to try.

I have a plan to try it, DMT, LSD, 2-CB and 5-MeO-DMT before I'm 60, so I guess I'd better get cracking as that isn't far away for me.

Mescaline is like the angry lover version of mushrooms. I did it once, two years ago to understand why it has been used, traditionally, as the baseline for comparison for psychedelic substances, and it was enlightening; it is certainly a tasting menu of the classical psychedelics, having at different points in the experience the flavor of stimulants, LSD, mushrooms and finally something all its own, but it is also much grittier and less loving than mushrooms.

Mescaline is _rough_. And honestly the "you are done with it before it is done with you" thing is 100% true, it is also very long lasting.

Same. I came to them as an older person (late 40s) who basically had only tried pot a few times prior, and nothing at all before late thirties. I don't drink.

My few experiences, the first few times, over the course of a year, spread apart by 3-4 months, went from extremely dark to .. just positive, except the last one, where I had no visuals, no bliss at all, and just came to terms with something else in our lives that was going wrong.

The dark ones were rage and anger, and now it seems just gone, like there's nothing there. Like a weight lifted, and seemingly long term.

foobiekr··on Distributed transactions in Go: Read before you try
Microservices with their own database are often a terrible design choice, but I will grant you it is one of the two dimensions that make sense:

1. is there a _very significant_ difference in the horizontal scaling footprint/model or demand (and demand is _only relevant_ if there is static footprint)? Home the function with a similar service, if there is one, otherwise yes, add a service.

2. is there a _genuine_ and _legitimate_ need for a different database, with completely independent schema, and not some horrible bullshit where you will end up doing cross-party transactions (and almost always failing to do so well)? Are you sure you need a different database or is your team just afraid of SQL and schema management (the usual mongodb garbage)? Is the issue that you don't understand how database security works? .. if all of these pass muster, then yes, ok, that's an OK reason.

Every architecture I've seen since 2013 at startups and big companies alike (since I do technical diligence professionally as a side gig) has been microservices or simple CRUD.

Almost all of the microservices ones were totally fucking wrong and had to be massively reworked, and usually multuple times, because they had no thesis at all for what they were doing and it was often - even mostly - an excuse not to have to learn their tools beyond tutorial level and/or a desire to play with new shiny or not read someone else's code. The CRUD guys were fine, they just did business until they needed to add caching, and so on, like real products.

foobiekr··on Distributed transactions in Go: Read before you try
Great advice. Microservices also open the door to polyglot, so you lose the ability to even arrive that everyone uses/has access to/understands the things in a common libCompany that make it possible for anyone to at least make sense of code.

When I talk to people who did microservices, I ask them "why is this a service separate from this?"

I have legitimately - and commonly - gotten the answer that the dev I'm talking to wanted their own service.

It's malpractice.

foobiekr··on Why TCP needs 3 handshakes
it's called 3-way because from the point of view of a network message diagram, there are three arrows which change direction at each step.

what it really amounts to is a three phase transaction.

foobiekr··on The Fastest Mutexes
I've always disliked that lock cyclic dependencies is discussed as a hierarchy when what it really comes down to is a linear order of locks.

The problem with lock _hierarchies_ as a concept is that a lock really should represent serialization of access to a particular pool of data, and should make no assumptions that it being held implies some other lock's domain is also held. The code that results when people do not maintain this kind of rigor is quite terrible, but hierarchies tend to steer people into thinking that way because they imply recursively taking locks.

Stated differently: locks should be taken and released in a fixed order - so locks are ranked - but there should not be a model where all lower-ranked locks must be held for a given lock to be taken. The lock protects its domain and the ordering of take and release is to prevent deadlock, but there's no requirement for completeness.

foobiekr··on Do AI companies work?
In particular:

"There is, however, one enormous difference that I didn’t think about: You can’t build a cloud vendor overnight. Azure doesn’t have to worry about a few executives leaving and building a worldwide network of data centers in 18 months."

This isn't true at all. There are like 8 of these companies stood up in the last three or four years fueled by massive investment of sovereign funds - mostly the saudi, dubai, northern europe, etc. oil-derived funds - all spending billions of dollars doing exactly that and getting something done.

The real problem is the ROI on AI spending is.. pretty much zero. The commonly asserted use cases are the following:

Chatbots Developer tools RAG/search

Not a one of these is going to generate $10 of additional revenue per sollar spent, nor likely even $2. Optimizing your customer services representatives from 8 conversations at once to an average of 12 or 16 is going to save you a whopping $2 per hour per CSR. It just isn't huge money. And RAG has many, many issues with document permissions that make the current approaches bad for enterprises - where the money is - who as a group haven't spent much of anything to even make basic search work.

How much market share do you have?
foobiekr··on Sleep duration, chronotype, health and lifestyle factors affect cognition [pdf]
A lot of people confuse the secondary effects of alcohol (basically, mostly, social permission) with the primary effects. Most developed countries have purged almost all ritual from their cultures, which means that there aren't really occasions for people to experiment with their behavior - and it provides air cover for engaging in riskier behaviors - and so alcohol provides the outlet for them.

Alcohol is one of the most boring psychoactive experiences there is, it's the safest, the most predictable and the most repeatable. There's nothing challenging about it - happy drunks are going to be happy drunks, angry/emotional drunks are going to be angry/emotional drunks, people who use the context of alcohol to excuse behaviors that they feel they would otherwise be judged for (promiscuity, "I love you guys! no I really do!", etc. etc.) are doing just that. The only drug with more predictability than alcohol is caffeine, with the common opiates being next in line for being absolutely predictable - do X get Y.

Alcohol is boring. Even pot or tobacco are more interesting, but they lack the social context that provides behavioral permissibility which is really what drives the ritual-lite use - going drinking on the weekend.

"all with their different nuances in how they alter mood and thinking patterns"

This is honestly not true unless you are including absinthe. Ethanol is the only active ingredient and it has one of the most well understood dose-response curves and one of the most heavily studied effects. The rest is all in your head.

There just isn't that much to the alcohol, it's very one note, moreso than any psychedelic, moreso than even smoking (where dose control significantly varies the effects) or even cannabis which is also relatively one note.

foobiekr··on AMD records its highest server market share in decades
Strategically, in global terms from a US-centric point of view, it would be very good if Intel could recover, as having the entire world reliant on TSMC would be bad for everyone. Also there really isn't any other org like Intel at the moment in the broader sense in a few ways (mostly advanced research).

That said, Intel really has nothing to fall back on. Internally, it is very much like many of the other big companies - run by executive whim papered over with justifications that are tissue thin. There are a lot of companies like this - Cisco, Intel, whatever the hell is left of IBM, Nokia, Lattice, NetApp, etc. - that will probably die this decade if they fail to reboot their executive and managerial cultures.

I have a lot of friends who have been in the great parts of Intel (the CPU design teams and, believe it or not, fabrication) and the crap parts (everything else, especially networking and storage [what's left of it], except maybe the perenially suffering ICC team). Pat has failed to make things materially better because the system that is the body of Intel is resilient to disruptions of the sort he is trying. A massive replacement and flattening of culture is required there and he has not been able to execute on it.

Turnover is coming for all the companies I list above. If I had to go out on a limb and suggest a longterm survivor from the list above, it might be Lattice. Otherwise everyone listed is driving hard straight to the ground internally, whether the market sees it or not.

Your logic is weird and false. There's nothing holy about dying.

On rare occasions the live vaccine actually reverts. Polio is an amazing story because the live vaccination campaign may have had collateral impact on the families of the vaccinated as they shed particles.

foobiekr··on What happens in a mind that can't 'see' mental images
For those who cannot visualize things: try the same experience with your eyes open. I can't visualize anything with my eyes closed - maybe black-and-white shadowy outlines if that - but with my eyes open I can visualize things kind of up above my head outside my visual field.

(There's an irony for me in that I had, until I got older, perfect experiential recall of short clips of time, including the feeling of motion, sound, etc. That faded to nothing in my forties. Enjoy being young, the worst part of aging is the very things that are you start to become threadbare.)
