the proposal is to use electric trains on caltrain tracks. they allegedly will run at 110mph which i bet is loud, roughly 40mph more than caltrain today.

the horns are getting better with grade separation and stations that don’t have crossings. they are very loud. you can hear them all the time. HSR will add 4 more trains per hour, which means a lot more train horns.

hopefully more grade separation is done by then. i can’t imagine any city surviving without it. there was a study done by caltrain about this and some crossings are blocked 20% of the time during peak hours today - and they want to increase train count by like 30%

Sorry, you gotta overhaul majority of your architecture and its components to scale by every 10x. It's not a single "scaling wall" to break through but it's more of a relentless stream of uphill battles. And this gets even more interesting when you reached to the point where there's no prior art for your problem, usually at hundreds of billions of users.

One interesting development in the area of cubesats is that most teams are shifting towards open source designs. In the past, cubesats were mostly using old and expensive hardware (like the pumpkin board). Now a lot of teams are using open source designs like PyCubed and building the electronics themselves. As a result, the price to enter the cubesat space has dropped dramatically. This has enabled a bunch of university teams to start building their own cubesats.

Many of these open source projects actually use consumer / hobbyist grade components instead of using commercial aerospace-grade components. The commercial hardware for cubesats is made with a specific manufacturing process that makes them resistant to radiation in space. However, this increases manufacturing costs. Also, most of the radiation resistant hardware being sold is sort of slow / outdated. The solution some open source projects came up with was to just take components from Mouser and run their own radiation tests on it then choose the ones that fared good enough to be used in space. That way they can make satellite boards for way cheaper.

Another interesting development is there are some startups now offering sub 50k launches for cubesats, such as launcher space. They essentially buy launches from SpaceX then outfit it with hardware to launch a massive amount of cubesats at once. As a result of the number of cubesats they’re able to fit on one launch, the prices are now relatively cheap compared to the hundreds of thousands if not millions required in the past. However, most of these startups are heavily subsidizing the cost using VC money so these low prices won’t stay forever.

Also, if anyone has any questions about cubesats feel free to AMA. I work at Isomer space which is a not for profit building cubesats. I would love to answer any questions about cubesats or our work.

I've been using the nightly branch for 6 or 7 years now and have rarely ran into issues. In fact our entire company runs nightly due to using the latest bastions and gateways servers that sometimes the version in the main repository do not support yet.

TL;DR (from skimming thru the paper) he figured that a song's spectrogram looks like a starry sky, so matching a song is like finding a constellation on the sky. How do you do it efficiently? By searching for simple features of your constellation, such as pairs or triples of bright stars - those can be pre-hashed to find matches instantaneously. Once a possible match is found, you compare the rest of the constellation. Nothing breathtaking, in other words. However, among all the men who talked, he was the one who both talked and did, and that's his achievement.
HTTP/2 was supposed to help avoid openning too many connections, but of course TCP in TCP is bad form. Now HTTP/3 is TCP in UDP, and has separate connections (more or less) per resource. I'm not sure what the big difference is between that and HTTP/1.1 with multiple TCP connections.

There is an argument for better congestion control. Which is funny coming from Google where they control the kernel on the server and the clients.

Hello Metamate! I have worked at a pretty wide variety of employers (from government to manufacturing to startups) so I think I can say that the grass definitely isn't necessarily greener.

If you can find a small team that is working on something cool that may be fun but at least for me I've seen an absurd amount BS while working in consumer robotics. I had a ton of fun but I was extremely underpaid.

My recommendation is try to take your time and find a new team at Meta. A change of pace would probably help you out! If you've been a good performer then it shouldn't be hard. This would be much easier than interviewing and less career risk. There is lots of really interesting work in AR/VR which is pretty unique.

The good news is you have tons of options, and if you did nothing but stay at your current role you will do pretty great!

Plants can transmit prions.

Grass plants bind, retain, uptake and transport infectious prions

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4449294/

"Prions bind to plants and bound-PrPSc efficiently sustain prion replication

Roots and leaves were washed thoroughly and analyzed for the presence of PrPSc by serial PMCA (Morales et al., 2012). The results show that even highly diluted PrPSc can bind to roots and leaves and sustain PrPC conversion (Fig. 1A). [...] However, both roots and leaves capture PrPSc efficiently, even at very small concentrations, equivalent to those present in biological fluids, such as blood and urine (Chen et al., 2010).

Animals can be infected by oral ingestion of prion-contaminated plants

After exposure, plants were extensively washed 5 times with water and animals fed with dried material orally. [...] All animals that ingested prion contaminated leaves and roots developed typical prion disease. Although the incubation times were significantly longer in animals ingesting prions attached to leaves and roots as compared with those fed directly with the brain material, the differences were not as high as one could have expected (Fig. 2A)."

---

Something developed sporadic prion disease (in humans its called "Sporadic Creutzfeldt-Jakob disease": https://pubmed.ncbi.nlm.nih.gov/29887134/ ), died from it, plants grew on the fertilized land and were eaten by deer, the cycle repeats.

CWD-infected deer shred prions in urine, feces, probably saliva too (the aforementioned paper mentions that this is enough for plant-mediated infection), a trait shared with scrapie-infected sheep, hamsters and, i assume, BSE-infected cows.

Transmission and Detection of Prions in Feces

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2803675/

"Oral exposure to prion-tainted blood, urine, saliva and feces have been suggested as modes of transmission for CWD and scrapie among herbivores susceptible to these diseases. Both CWD and scrapie infection is thought likely to enter the body through gut-associated lymphoid tissues, in Peyer's patches in the alimentary tract. Moreover, the presence of the infectious isoform of the prion protein, designated PrPSc, in Peyer's patches suggests alimentary shedding of CWD and scrapie prions into feces. [...]

When noninfected Syrian hamsters were cohabitated with Syrian hamsters orally infected with Sc237 prions, we observed 80–100% infection rates within 14 days after oral challenge."

Also, birds can spread prions in their litter:

Crows don't digest prions, may transport them to other locations

https://www.sciencedaily.com/releases/2012/10/121017181250.h...

"Crows fed on prion-infected brains from mice can transmit these infectious agents in their feces and may play a role in the geographic spread of diseases caused by prions, such as chronic wasting disease or scrapie."

That is not the pronunciation they encourage, read the whole line:

"Rebol" is definitely not meant to rhyme with "cause". The common word in the two is "rebel", the emphasis is on the way the syllables break and the sound of the first syllable, not on making it sound like "rebel yell" (which would be a bizarre way to pronounce "Rebol"). This is present to emphasize that while it looks like it could be made into "ree-bowl" or something, it's not supposed to be.

> This thing and Rust: "constant" -> something unable to change "mutable constant" -> a changeable constant...what?

"What?" indeed. Rust doesn't have "mutable constant". Rust's "const" is actually a constant, unlike in C where "const" means "Sort of immutable, although maybe not".

I guess maybe you've been told something about Rust like "let is kinda like C++ const" and so you've come to the erroneous conclusion that somehow "let mut" means "mutable constant" but that's just because you didn't really understand, blame either your attention or the poor explanation, it's surely nothing to do with Rust which has never said this is "mutable constant" since that's nonsense.
When they built the San Jose stadium (in a wetlands reclamation area), they ignored their environmental mitigation plan starting on day one.

I know bicyclists that were severely injured as a result (they set up unsafe and illegal temporary bike lanes instead of using the ones in their plan, then neglected them).

This was reported to the appropriate local authorities, but they said no one actually had the authority to enforce the environmental plans.

I assume high speed rail will proceed in the same way, and these decade long delays will be completely pointless in the end.

The inhabitants don't lose.

Play your scenario out.

A bunch of poor people buy 100 acres of land for $1, and they turn it into a paradise.

It becomes cool, so rich hipsters wanna buy up chunks to Instagram it.

The first person sells a patch of land he bought for $0.01 for $1M. Suddenly, property tax on everyone's $0.01 parcels shoots up from $0 to $12,000 per year.

These people have no jobs, so they can't afford $12,000 in taxes per year, so they're all forced to sell their properties to other hipsters on Instagram for $1M, too.

Well guess what?

Now they're millionaires.

I mean, technically, not. They've got some taxes to pay. But you get the idea.

No owners "lose" from property values shooting through the roof. ESPECIALLY not leveraged owners (mortgage holders).

>> This is not true for nuclear energy: even very remote bystanders unwilling to take the risk are majorly exposed.

> Nah. We're all responsible for the choice. That's how democracy works.

If citizens directly decide upon a given subject then a referendum about nuclear energy is necessary. In nearly all nations there was none. Therefore we aren't all directly responsible.

In practice elected people decide, and in Western democracies they theoretically bar the majority from oppressing any minority ( https://en.wikipedia.org/wiki/Tyranny_of_the_majority ).

However it could not work this way for nuclear energy because dismissing concerns (about safety, about dangerous waste long-term effects...) is sufficient and was easy: at first by declaring that all those reactors are under control, that any real problem is so highly improbable there is no real risk. Nuclear experts convinced many politicians.

This stance was tainted after each mishap (TMI, Chernobyl, Fukushima...), and the approach mutated into minimizing the effects of mishaps. However less and less politicians were willing to take the risk.

Renewables then began to gain traction, as more and more citizens and politicians see them as adequate and alleviating many challenges (risk, waste, dependency towards uranium...), and renewables quickly gains terrain while nuclear is more and more stuck.

The new approach is to pretend that renewables aren't adequate due to their intermittency, albeit many studies and existing technologies do offer efficient ways to compensate it.

The effect on democratic nations' choices will be clear in 5 to 10 years. However in such a context whatever the result will be pretending that we will all be responsible for it is IMO highly debatable.

>> No, given the RBMK architecture the positive void coefficient isn't a major flaw.

> The results speak for themselves.

I repeat: each and any existing nuclear reactor car suffer a meltdown, this is absolutely not specific/proper to RBMK. Moreover there is no perfect containment, in some configurations they may isolate the reactor for only a few days.

> The data on nuclear speaks for itself

It highly depends upon which data one considers, in other terms which ones are describing reality.
Experiment:

1. Open TextEdit.app

2. Type some random characters.

3. Attempt to quit with Cmd+Q.

4. A dialog box shows up, prompting you to save the file. Hitting Tab just cycles between the "Save As" and "Tags" text fields. There is no way for me to select the "Delete" button with Tab.

Challenge: quit TextEdit.app in that situation with they keyboard, without using the mouse, and without saving a file.

That's a broader topic btw: Apple's apps often make the Tab button only cycle between text fields. In Safari when logging into Spotify I can't reach the "Remember me" checkbox with Tab. It only cycles between the login and password textfields and the URL bar. Luckily, other browsers don't have this flaw.

It's a law. You can just put in exemptions.

- "You may not pay more than 5% of your income in land tax".

I don't see the issue. We don't tax income at 20% with no deductions. We don't place a sales tax on all goods equally. We don't tax corporations the same way we do individuals.
