>In 1964, Japan was able to build its 320 mile long Shinkansen from Tokyo to Osaka in just 5 years for less than $12B, inflation adjusted.

Another important factor here is the cost of construction: the California project will all be above-ground, AFAIK. However, a significant portion of the Tokaido line between Tokyo and Osaka is through tunnels, so the difficulty of construction was far greater.

For a more apples-to-apples comparison, Japan is currently building the [Chuo Shinkansen](https://en.wikipedia.org/wiki/Ch%C5%AB%C5%8D_Shinkansen) line between Tokyo and Nagoya (286km/178mi), which will be a 505km/h maglev train that's 90% underground, as they have to tunnel through various mountains. It's projected to be finished in about a decade I think. Current costs have risen from the initial projection, and are at about 7 trillion yen for the first leg (Shinagawa to Nagoya), which at the current exchange rate is about USD$44B. But remember, that's about 160 miles of tunnels through mountains, plus all the rolling stock (which doesn't actually roll LOL), including the deepest tunnel in the country, and a line which isn't even conventional rail, it's a maglev track. By comparison, California is spending all that money on an above-ground train, in a place with excellent weather, using the same rail technology Japan was using 50+ years ago.
Conway's Game of Life for curved surfaces (2012)
Alito said "[the Constitution] means what people would have understood it to mean at the time it was written." One can certainly accuse Alito of cynically ascribing modern Republican party politics to the framers, but I don't see a "smoking gun" here.

To paraphrase his opinion on Dobbs, ex facto the Constitution grants neither an explicit right nor prohibition to abortion--the framers saw it as a legal "gray area" to give a liberal reading of history--so following the 10th amendment, any regulation of abortion should be devolved to the states. Perhaps it is better if abortion were nationally legalized, but Alito's opinion seems reasonable if we are following the rules to the letter.

Re: the Founders, they do not write about the "tyranny of the past" nearly as much as they write about plain ol' "tyranny" of living govts--maybe the closest is Federalist No. 14 or Thomas Jefferson's 1816 letter to Samuel Kercheval "We might as well require a man to wear still the coat which fitted him when a boy, as civilized society to remain ever under the regimen of their barbarous ancestors." Conversely, we can find tons of examples of the Founders being inspired by classical/traditional sources e.g. Greek (Plato, Aristotle, Plutarch), Roman Cicero, Polybius), the bible, English Common Law etc. It is clear the Founders were neither iconoclasts nor Trotsky-style "Permanent Revolutionaries."
At a large enough scale you can do most of these processes by automation, except the actual courier delivery. And well, at least UPS has actual identified locations in their vans, so just going by location+barcode might be somewhat practical for them.

Or more recently, Brightline built a private high speed rail in Florida for $5 billion, spanning 170 miles. It’s hard to imagine a plausible reason this should cost 100 billion, especially given the fact they already have Amtrak rail running through California
Instead, it should be the good old days when Congress had a purpose and the Executive wasn't legislating. Chevron is from 1984, not the 1930s.
No. By the time this rail is done, the last mile will be done by teleporters.
Hydrogen as fuel won't work, yes; but generating it and immediately making hydrocarbons or ammonia or other chemical feedstocks with it is perfectly feasible. It's already being done. Just not with electrolysis.

If you're in San Francisco, the Asian Art Museum in Civic Center has an amazing Kushan and Gandharan art exhibit.

There is a similar set of exhibits at the Harvard Art Museum as well, but they don't really bring up the Yuezhi and Gandharan aspect due to donors and politics.

The Kushan and Gandharan era is also a much less researched portion of Central and South Asian history sadly, despite being an interesting tapestry of Indo-Iranian and pre-Turkic Central Asian history, and one of the first forms of proto-globalization.

Would love to visit Dunhuang, Pazyryk, and Ai-Khanoum as well as some point but that probably not happening in my lifetime.

"The Khyber Pass: A History of Empire and Invasion" by Paddy Docherty a good intro book as well about this historic (and imo underappreciated) connection.
Cash is progressively disappearing, in particular as PayPay has gotten foothold.

The main gaps that were filled:

- interpersonal payment is now easy. 10 people eat together, splitting the bill is now sharing a QR code and 30s of operation for each, no exchange of contact, nothing finicky, and it can also be done later (no tap needed)

- phone networks are fast enough to make the transactions near instaneous. We're talking 3s at most in a sheet mobile environment. 1s with a wired POS.

- phone are secure enough, being already the central part of our electronic life.

All in all, cash will always be used somewhere, but even grandma's vegetable stands are starting to accept QR codes.

I believe for the K210 Kendryte/Canaan simply grabbed the latest Berkeley Rocket commit, didn't change a thing, and simply added peripherals (including an NPU) around it to make a complete chip.

And, yes, that latest commit at the time was priv spec draft 1.9.1, which is quite different to what eventually got ratified.

For a while people trying to use the K210 thought the MMU was broken but it's not -- it's just an older spec.

Good luck cutting down any modern Linux kernel to boot in 8 MB RAM! Being able to do that might even predate Linux working on anything other than x86.

xv6 works fine though.

Edit: I was a little bit off. Linux 2.0 required 4 MB, recommended 8+, and already worked on Alpha, SPARC, MIPS, PowerPC, ARM, 68k. Linux 2.2 (1999) required 8 MB, recommended 16+.

Why China's Central Bank Could Become More Like the Fed
Forgot to answer your actual question: Delta does directly handle its ramp operations at ATL, as well as at BOS, CVG, DTW, MSP, MIA, and SEA. But in the US there are state and federal labor laws to consider and where possible, they, like the other major airlines, offload a lot of staffing generally to Unifi or similar specialist staffing agents. Unifi used to be part of Delta until spun off and sold around 2018 if I remember correctly. Beforer then they were called Delta Global Staffing and primarily handled temp hiring. Now it is 49% owned by Delta but covers hiring for United and Alaska and a few others where possible, and provides the training and certs and all that as well, temp or full time, where possible, including some ramp positions at ATL. SLC, LAX, LGA, JFK are all Delta hubs and positions for ramp agents are entirely absent on Delta's career's page, but on Unifi there are pages and pages that cover almost everywhere in North America where Delta flies. Compare Unifi's open careers page: https://unifi.avature.net/careers to Delta's: https://delta.avature.net/en_US/careers and it should be pretty obvious as to the difference.

This is a bit of generally not very useful osint info but a subdomain search on HR platforms can reveal at least to some degree the labor situation at a lot of entities. avature has over 4000 subdomains in their dns records on securitytrails alone. Not all are for staging or VPN access or SMTP. Some are no longer active, but most do resolve. That's medium potatoes at best compared to the 10k+ at bamboohr. Although if you are doing OSINT you're probably not going for a job at a lot of these staffing agencies anyway. Ever since I was asked to leave a Cutco presentation in 2011 I haven't applied for a job since and I've been poached multiple times and am basically retired at 37. But this is a neat trick and I like dataset gathering for its own sake, and it definitely gives off an interesting view of the economy that may or may not reflect how any one feels about how things are going.

(If I need a job, I prefer fangraphs or baseballprospectus anyway, but they aren't hiring anyone who filed tax returns as professional gambler, sadly)

The programming would be writing the knitting pattern. Not executing it.

How many knitters write knitting patterns? How many know how to algorithmically modify a pattern to suit their body type?

I used to teach computing at night school in the 1980s and as a metaphor it was remarkably useful for motivation with older women who were in an "I can't do this" frame of mind. Pointing out that if they did any design work in knitting or crochet, or at least could understand how to modify a complex pattern e.g. around a neckline, or cabling, they were already "doing it"

A jacquard loom is for weaving. Knitting machines are very programmable.
They do share code and data, the links are at the end [1,2]. The results do seem to more or less reproduce, but I'm also not entirely convinced by the explanation they provide. I was thinking that the difference is attributable to the shenanigans that SELFIES do with valences to make sure that all strings are valid (thus entirely derailing the model after a single mistake rather than getting the string thrown out), but I couldn't figure out how to prove it.

Who was the first person to propose FFTs for faster polynomial multiplication?

Got curious about this recently. I’m not great at citation tracing, but did make it back to this 1995 paper by David Eppstein [0] where he uses it to efficiently solve Subset Sum after an incremental update. Surely Knuth’s TAOCP had it even earlier?

The fact that FFT polynomial multiplication also lets you solve Exact Subset Sum with Repetition in sub-exponential time came as a real shock to me. [1] Crucially, this algo is O(N log N) where N = the maximum element, not N = the set size, so it isn’t a P ≠ NP counterexample or anything.

Ok well Brightline, a private company, built 170 miles of high speed rail in Florida for $5 billion 6 years ago.

I'm being pedantic here but... I think the correct statement is "the more context an LLM or human has TO A POINT, the better decision it can make".

For example it's common to bury an adversary in paperwork in legal discovery to try to obscure what you don't want them to find.

Humans do not do better with excessive context and it is appearing that although you can go to 2m tokens etc. they don't actually understand. They ONLY do well at "find the needle in the haystack, here's a very specific description of the needle" tasks but nothing that involves simultaneously considering multiple parts of that.
That's why I'm introducing my new Quantum Heisenberg computer. It works until you observe it.
I’ve wondered if this existed, to simplify writing a system that parses and processes RSS.

Frankly I’d go a bit further and spit out events, so people can code “give me the next entry” without having to mess with polling lots of rss endpoints. Just tell me when there’s a new entry.

Or turn it into a web hook so you just code the parsing, and delivery is outsourced.

Polling for changes is a terrible design. The source has to serve data on repeat to every reader that is set up to check once every week/day/hour/minute.

At the very least have a distributed cache that is set to return only the entries created after generally agreed timestamps. (Please tell me that exists now, or why it’s a bad idea.)
Many thanks! Book marking now,

Almost everyone uses MiniLM-L6-v2.

You almost certainly don't want to use MiniLM-L6-v2.

MiniLM-L6-V2 is for symmetric search: i.e. documents similar to the query text.

MiniLM-L6-V3 is for asymmetric search: i.e. documents that would have answers to the query text.

This is also an amazing lesson in...something: sentence-transformers spells this out, in their docs, over and over. Except never this directly: i.e. it has a doc on how to make a proper search pipeline, and a doc on the correct model for each type of search, but not a doc saying "hey use this"

And yet, I'd wager there's $100+M invested in vector DB startups who would be surprised to hear it.
And it definitely is a treat to accessibility. RSS accessibility!

I use Handbrake to encode piano practice sessions to be sent to the piano teacher. Since the teacher cares more about audio quality I configure Handbrake to use the original audio stream. I dial down the video quality from the default 24 or so to 28 for lower quality. Artifacts are somewhat visible but acceptable. The multi-gig files from the camera become small enough to be emailed directly.

However while Handbrake supports this use case perfectly I don't think there's a way to re-encode the audio but keeping the video. I guess that's when this submission comes handy.
Meanwhile they made almost impossible to restore a local chat backup. Yay!
> I'm not completely sure how this squares with the fact that I can listen to a song that I like dozens of times and still enjoy it

Well, it raises the question of: does listening to a non-repetitive song, repeatedly, make it repetitive? Is there a certain gap of time that, even if something repeats, that it no longer feels repetitive?
It's like Tim Berners-Lee being referred to as "Web Developer" :)

> You will notice that past a certain angle, the lift starts to decrease, and is replaced by a lot of drag, a force trying to slow down the wing. This is called a stall, and it limits how much lift a wing can create at any given speed. A proper airfoil geometry can generate more lift before stalling, and creates less drag for a given amount of lift, which is why most airplanes use them.

I'm a bit of a novice, so it sounds like this is the same explanation you're giving. What is the article leaving out?
Dns is a hierarchical recursive service. When you make a DNS query, such as requesting "www.google.com", you typically do not do the full resolution in your application - but you do make the DNS query on your application. What you instead do is make a DNS request to your configured "recursive" server, asking it to make further queries on your behalf if it doesn't know the answer.

We do something obviously silly for this exercise - we assume that all caches are cold, because the point of a recursive DNS server is mostly to act as a cache. So we'll be going through a bunch of queries that usually are simply answered from cache instead.

At the top are 13 "root dns servers". These return responses for top level domains, such as ".com". When you want to request www.google.com, first you have to ask who controls ".com". Your recursive server (just "you" from now on) sends a request to the root servers - "Who are the nameservers (ns) for .com?" Also written as "QUERY .com NS". The root servers will answer - "A(answer) .com NS 1.2.3.4 AA (Authoritative answer)". The root dns servers believe they are the authority for the "." Zone, because they are.

The recursive resolver, you, then use this knowledge. You ask a similar query of the ".com" nameservers - "Q google.com NS" they respond, giving you an authoritative answer for google.com "A google.com NS nameservers.google.com AA". But you don't know who the nameservers for google.com, how do you resolve this loop? DNS has a mechanism for that. It includes a few extra records, called glue records, to close the gap. "X(tra) nameservers.google.com 8.8.9.9"

Finally, you know who the nameservers for google.com are - You then send them a request. "Q www.google.com A(Internet Protocol)" you might instead send an AAAA request, for an ipv6 address, instead.

There's a ton more - Support for text records of arbitrary type, support for addressing schemes that no longer see use, etc. but thems the basics. You can run your own whole Internet, if you want to - Just build your own recursive server pointing at your own roots, and then host whatever you want on whatever up you want - Just don't expect to be able to connect to the real Internet at the same time. Also basically everything phones home and breaks. :shrug:
