<p>Is it correct to rephrase PolarQuant as “embeddings vectors but as complex numbers” since polar vectors were represented with i complex numbers in other fields of applications? Would this open a new field of transformations using complex number arithmetics?<p>Edit: I believe I have my math concepts all wrong. Vectors are currently represented with xyz coordinates, so that can be our complex number equivalent. This paper saves memory size by ‘simply’ transforming this “complex number” into its polar form (radius/size and angle). Since you use less bytes on angle + radius you then always refer to that polar form instead of the regular vector/complex number part. If I have my concepts correct this idea is simple and genius.<p>Edit 2: I may be missing the forest for the trees here. I’ll try to learn more from the actual sources if I can.</p>

<p>I work at a enterprise tech company that has kinda of a monopoly on its market. The hate I get when I mention I work there is so big… I can only imagine what a MS Teams dev would get these days. The worst is when they complain about the UI… when I’m one of the few frontend focused devs there.<p>I’ve had a government worker stop processing my request and start complaining about the product I build. Lost a good half an hour trying to understand their bug but we didn’t get anywhere</p>

<p>Yep, bugs are already just another cost of doing business for companies that aren’t user-focused. We can expect buggier code from now on. Especially for software where the users aren’t the ones buying it.<p>Disclaimer because I sound pessimistic: I do use a lot of AI to write code.<p>I do feel behind on the usage of it.</p>

<p>This was 2008 when they were fighting for titles still (turns out they were robbed and the FIA knew about it and let it play out).<p>That said I imagine what Jonathan Wheatley would be able to achieve in a task similar to this since he had the Red Bull team maintain a consistent sub-2 second pit stop at Red Bull and he was able to significantly quicken the Sauber one this year.</p>

<p>I like this. I have crafted a Claude Code docker container to similar effects. My problem is that my env has intranet access all the time (and direct access to our staging environment) and I don’t want a coding agent that could go rogue having access to those systems. I did manage to spin up an iptables based firewall that blocks all requests unless they’re going to the IPs I allowlist on container start (I was inspired by the sandbox docs that Anthropic provides). My problem right now is that some things that my company use are behind Akamai, so a dig lookup + iptables allow does not work. I’ll probably have to figure out some sort of sidecar proxy that would allow requests on the fly instead of dig+iptables.</p>

<p>So they automated most of the production in order to compete with cheap labor. It didn’t bring the manufacturing jobs as we think of them back: it did something better.</p>

<p>I’m not not a lawyer at all and I have no real idea. My guess is that existing visas are already printed and henceforth there is no petition anymore, you have a status or visa already. Since the old petition didn’t require the payment, you don’t need to show proof of payment now. But lol if I actually know how this works, can be anyone’s guess.<p>My guess is that if this goes forward new h1b visas petitioned while the worker is outside the US will have a line saying “must show proof of payment” or something like that, while petitions while in the US won’t have that line on their visa stamp</p>

<p>Yes, but a visa stamp renewal is a visa “application” while the document that allows the application is the “petition”, which is the word used on this text and the step requiring the payment.</p>

<p>IIRC the author compares brain scans and recognition abilities of children of hunter gatherers that where sent to school vs same age relatives that were not. I’m bringing this up from memory now and I’m not so sure of this, but this claim stems from some studies of the author</p>

<p>Literally one of the main points of the book: the church’s mandate and enforcement of monogamy in Europe lowered violence so much that a different kind of society emerged.</p>

<p>The author uses mostly hunter-gatherers tribes/societies in different continents as the control groups, usually. Most of his work is in anthropology.</p>

<p>I do not have the time now to craft you a full answer as I don’t have the book on hand and have only been commenting from memory so far. But to give you a quick answer: I don’t think all of it is shallow, especially given the format: the book is mostly a prose re-writing of the author’s own peer-reviewed anthropology scientific papers. Most of the authors claims are backed by actual papers for reference on the footnotes. As for replication it seems that the author himself replicated some of his studies with different hunter gatherer societies in the world. It’s been a good while since I read it.<p>I can tell you from my personal experience that the info there has helped me understand the differences between how people think in Brazil (where I come from) and how people think here in the US. Could it be me pattern matching? Possibly<p>I wouldn’t expect all of it to be true, but I would be very surprised if most of the sources the author provide are false or lack theory and tests, since he explain control groups and experiments in details.<p>I’m not that married to the book either, as I find some claims rather bold (like the Italy divide)<p>The title does sound catchy tho<p>Edit; the author’s main point is how the papal rule on monogamy changed Europe and its colonies to this day, which I didn’t capture on my main comment. Lots to unpack there</p>

<p>Yes, your point and other points around the web I’ve seen make his argument about north and south Italy very controversial to say the least. He does have data to back it up, where he presents distance to nearest church as a predictor for how well a population will fare, and south Italy didn’t have the churches that north the Italy had</p>

<p>I meant it as “is responsible for” or “explains”. The author doesn’t seem to make any judgement in over the other, but he presents polygamy in a society as a causation for male violence. Sorry for that, English isn’t my first language</p>

<p>I don’t have the data but I assume the corpus available to train an LLM is majorly in English, written by Americans and western counterparts. If we’re training the LLMs to sound similar to the training data, I imagine the responses have to match that world view.<p>My anecdote is that before LLMs I would default to search Google in English instead of my own native language simply because there was so much more content in English to be found that would help me.<p>And here I am producing novel sentences in English to respond to your message, further continuing the cycle where English is the main language to search and do things.</p>
