If you hand me a room temperature superconductor but your published recipe doesn't work for me, I'm about 95% as excited as I'd be if I had the right recipe.
Everyone is parroting the same thing over and over again, but no one is going into the whys. Why do this, what's the benefit, how will it thwart this or that type of attack. New books on the subject tend to collect these guides, distill them a bit, and parrot it all over again.

A healthy ecosystem provides enough shelter to the preys for sustaining both preys and predator. It does not modify the ecosystem in the way than a beaver does. Not even close.
no one gives a shit at all about any of that if anyone shows up this week with a room temperature/pressure superconductor.

whoever eventually does it gets a nobel prize and the front cover of whatever journal they pick, and then a chapter in the history of the 21st century.

Look no further than car dealers lobbying for laws that all sales must go through dealers, for example. Or car companies lobbying for laws that incentivize people to own private cars by making alternatives infeasible and unsafe.
Imagine, if you will, looking both ways and slowly rolling through a stop sign; and also imagine running a stop sign at full speed and not looking. Not all running stop signs are equal. It's not the law that matters.

Also, cars aren't creating the risk. Drivers are.

That depends on the environment. Natural light fights against the functioning of light-emitting displays. Reflective displays cooperate with natural light.

You in the dark? Use OLED. Under the sun? Use EPD.
This has been driving me crazy for years now. AWS still doesn’t have complete IPv6 support, in 2023. They are front and center to IPv4 exhaustion yet seem unconcerned.
Lambda does support private IPv4 networks though.

If you can, I would always call the hotel and ask for price matching. 9/10 they say yes and sometimes I even received a free room upgrade because I paid with them directly and not a 3rd party.
Fruit of the poisonous tree: Companies that started out by thumbing their nose at laws will never be honest with their employees, customers, and shareholders.

AirBNB is a good example. They didn’t lose their soul when they made it big - they never had one to begin with.
Independent validation. Physical peer review.

That basically helps rule out scammers or gross incompetence and ensures that even if initial attempts to replicate fail because of the complexity or lack of clarity, people keep trying.
I think you're missing the point: there is no such thing yet as a room temperature superconductor. If they have such a thing, they made it. If they failed to document the process well, that's a separate issue from whether the sample they have actually is a superconductor at the temperatures described.
> Or a write through cache in each region.

This is something I want to play around with using Cloudflare. I wonder if there’s enough of a guarantee for a user to “stick” to a node that you could use Workers KV as an eventually consistent write through cache for user unique data and a Durable Object as a strongly consistent write through cache.

I feel like that would give a pretty solid balance, wouldn’t it?
do you live in NYC? Mopeds and e-bikes are all over the sidewalk, and they just caused a major crash on the Manhattan Bridge bike (not moped!!) path.
Insulation distributes heat release over time, at the cost of temperature control. If its going to be used all the time, especially with multiple units, distributing release over time doesn’t change much but the delay between first turning it on and full effect to the surroundings, and the impact on temperature control is still there.

Insulation is only effective with intermittent use.
I think the resort fee is a way to get around either lodging taxes or franchise royalties, as they might specifically apply to lodging portion of a hotel room’s price.

Hotel room night tax rates are almost always much higher than general sales tax rates. The hotel might pocket more if they sell a room for $200 + hotel tax + $50 resort fee + sales tax rather than $250 + hotel tax.
what are you talking about?

the authors haven't given anyone a sample to inspect, so every other solid state physics lab in the world is instead trying to follow the notional recipe and test their own sample.
i think you’re misunderstanding what GDP (gross domestic product) means. it’s basically a measure of the total revenue in a country’s economy. it has nothing to do with “productivity” in the sense of efficiency.
> And GDPR has, by design, extra-territorial effect: https://gdpr.eu/companies-outside-of-europe/

Yeah, but they have no jurisdiction.

Millions of EU citizens use WeChat, which is obligated by Chinese law to collect information not allowed by the GDPR, and the EU have not and will not be able to enforce an "extra-territorial effect" against Tencent.
As per the OP this is an NYC specific phenomenon. The e-bike/moped delivery drivers will blast through stop signs and red lights at 20mph with pedestrians in the crosswalk. As a pedestrian having a bicyclist slow rolling a stop sign on pedals feels safe (they aren't that heavy or fast), but getting buzzed by a dude with a motorized vehicle rolling at 20 mph feels actively dangerous and I have seen enough crashes to think that this is not just an impression.
Something I haven’t considered until today is that the resort fee is probably a tax avoidance scam as well.
Quick feedback: I really thought the “ROI Calculator” on your landing page was meant to be interactive not a screenshot so was wondering why it didn’t work. Any chance it could easily be made interactive by embedding the actual software there?
Agoda usually has better coupons and sometimes mobile specific ones, better than Booking if they have the same listing. But the prices will also vary. Same parent company.

Ehhhhh I'm not sure I'd say smart, just that low effort trolling or manipulation is harder. Plenty of obvious sock puppets and ideological hacks, and the simplified text system makes it easier in a way.

"Marketing and Propaganda works, even if you understand how marketing and propaganda works"
What the poster is saying is objectively true. At least in NYC. I would add they are particularly dangerous to pedestrians.

Whether the poster has previously slow rolled through a stop sign or cars are dangerous to bikes are separate points.

I would say e-bikes are not the root problem. They are fine. It is the drivers not following any rules is the primary problem.
This is a very uncharitable reading of what he wrote.
That particular code has been retired because after a quite a bit of trying things that weren’t quite right we understood the problem and found a better way to do it. I’m doing the next round of related work (logically modeling XSLT schemas and associated messages in OWL) in Java because there is already a library that almost does was I want.

I am still using this library that I wrote

https://paulhoule.github.io/gastrodon/

to visualize RDF data so even if I make my RDF model in Java I am likely to load it up in Python to explore it. I don’t know if they are using PyPy but there is at least one big bank that has people using Gastrodon for the same purpose.

The beam width is 0.65° at x-band. If it's off pointed by 0.5°, the signal will be 7 dB lower (which in this case, is a lot).
I've been using third party ROMs on Pixel 3. They receive monthly security updates to some extent, but obviously the hardware specific "vendor binaries" are still outdated. Frankly, I cared more about the open nature of the ROM than about security/privacy. These days, I assume all my data is available for sale everywhere anyways.
Yeah, it seems to be an ever increasing issue. I wonder what would be the minimum server specs to successfully fend off the hug of death.
Predatory pricing is already illegal. Or at least was, but apparently SCOTUS weakened it substantially.
>I wonder why that isn’t happening?

Because it's been ~10 days since it was announced in a preprint article.

The complexity and resources involved are much higher than "building websites with React", so, things happen on a different timescale.
I said I "slow roll" thru stop signs. And and like most bikers, if you are at a stop sign and there's no peds and no oncoming cars, its pretty safe to go thru the stop sign. Just like how everyone jaywalks in NYC. If I get a ticket for that, I own it but at least I'm not putting other peds at risk.

But the crux of the issue is that delivery ebike are riding recklessly. Any the majority reason for this is because they are paid by the number of deliveries they complete. This creates an incentive for them to take risks which a normal rider would not do. If the didn't have that incentive, they would probably operate in a much safer manner.
Actually, as a cyclist, I would tend agree with the person you're replying to.

A major factor is that (the vast majority of) people can't hop on a pushbike and just go 20+ mph. Non-athletes typically ride about 12 mph when they first hop on. By the time they develop the muscles and cardio to ride a sustained 20 mph, they also develop the bike-handling skills to reasonably ride that fast, as well as an awareness of when it is appropriate to ride that fast.

In contrast, anyone who hasn't ridden a bike since childhood can hop on an eBike and be going 20 mph seconds later. They often don't know how to handle a bike around other people.

> If I were required to bike on the road instead I simply wouldn't do it, it's far too dangerous. So we'd probably end up having to get a car and if, heaven forbid, I were to get in any kind of an accident a pedestrian would be considerably worse off.

A collision, not an accident. And you make it sound like something that happened to you as the driver of the car.
IMHO, the progression that explains the current state of things is:

{vendor power decrease} led to {fierce competition on unit price} led to {consolidation of vendors and manufacturing cost minimization / volume maximization} led to {offshore lower cost manufacturing} led to {decreased design agility}

Consequently, there's less appetite for the type of wild experiments that characterized 1950s and 1960s design.

Low volume = not interested

It used to be that tech was insulated from the phenomenon, but I think Google shows the same progression playing out. It just took tech longer to consolidate.
Have you spent time in Manhattan? It’s common to get buzzed by bikes going 15mph+ down sidewalks on streets (not avenues) where the street is mostly clear (and cars don’t ever go very fast on streets anyway, they really can’t).
EmDrive was supposed to work better with Superconductors!
Armadillos are just as common in Mississippi, Alabama, Louisiana, and especially Texas compared to Florida. I don’t feel like that tells the full story.

There are many more problems with animal ag, not just the area.

Climate change, resource depletion, deforestation, loss of biodiversity, pollution, overpopulation, soil erosion, and overfishing are all symptoms of ecological overshoot. Agriculture is a key culprit in 5 out of 7 of those symptoms, and animal ag accounts for 80% of all agriculture.

20 years ago with fridges is a bit of a funny one because by then most had gotten rid of the nasty CFC's. But, even at that, it looks like today's fridges are _orders of magnitude_ more efficient to run than those from about 15-20 years ago.

For an oven and hob, the basics haven't changed, but my previous flat had a $600 oven that was silent, leaked practically no heat, preheated in a couple of minutes and came with nest features like an auto switch off. My new home has a range from about 15 years ago that cost 3x that, takes 20 minutes to preheat, has massive cool spots in the oven, and is noisier than my dishwasher.

For TV's, 20 years ago we were using CRT's to drive 480 vertical lines for the most part. Nowadays, you can get a 1080p HDR led TV for $200 that used 1/3 of the power of the CRT.

I've been running a FreeBSD server (web, email, DNS) for 20 years at this point, so consider this a long-term review.

It just works! Specifically, keeping the system running and up-to-date is very low-maintenance. On the software side, the pkg system has been great—and a welcome change from manually installing ports from source. On the OS side, security updates and upgrading major and minor versions have all been painless.

I haven't run a Linux server long-term, so I can't compare, but my biased perception from the outside is that it seems like Linux changes more rapidly and requires a bit more hands-on management.

They have 30GW of renewables in the AEMO connection pipeline at the moment, ~7GW greater than entire continent coal generation (which will add to current renewables capacity) [1] [2]. Batteries are scaling up to consume grid services revenue and drive out thermal generation [3].

Also of note: "NEM total emissions declined this quarter to the lowest Q2 level on record, of 28.7 million tonnes of carbon dioxide, 6.6 per cent lower than Q2 2022, whilst emissions intensity dropped 4.3 per cent to 0.61 tCO2 e/MWh."

"“Rooftop solar generation increased 30 per cent from Q2 2022, which reduced electricity demand from the grid. Coupled with higher renewable output, wholesale prices were zero or negative nine per cent of the quarter throughout the NEM, a new Q2 record,” Ms Mouchaileh said." This bears repeating: 9 percent of the time, the wholesale cost of power is zero or negative.

>but what's stopping a random internet anon from gluing a crumb onto a pipette and taking a picture of it?

Nothing, just like nothing would stop a random internet anon from faking a video of the same thing. Even if that existed, it still wouldn't be sufficient evidence (especially given this is a different synthesis than the one in the paper), it would just be much more overblown.

Wait for lab reconstructions, or at the very least, this anon's writeup, instead of following a live twitter blog and then complaining that it's not conclusive.

I have started working for a startup recently. My main responsibility is to develop networking features for our cloud on bare metal. We started ipv6 by default but soon we discovered that the biggest issue is "not" the setup side. Ipv6 setup is actually quite straightforward, if you're starting from scratch. The biggest problem of ipv6 is that the ecosystem is not ready for it, at all. You cannot even use github without a proxy!
Hence, we had to start implementing ipv4 support immediately, because VMs for developers that only has ipv6 is almost useless.
This is illegal btw.
Presumably they’ll add a second toggle for “show total cost including all fees and taxes”, which will give every cent you’re going to pay, except special surcharges.

I can’t give a blanket statement for the US, but in the cities I’ve lived in, cyclists of all powertrain types are supposed to be on the street and not the sidewalk.

When I was a bike commuter, I’d on rare occasion take a stretch of sidewalk, slowly, to avoid road construction and hazards I just didn’t feel safe traversing. I would not bother a single pedestrian and was probably coasting at the speed of a jogger/runner. None the less I’d still get yelled at by cops to get on the road. Meanwhile cops do nothing when, at least in Downtown LA, cyclists are running red lights.

I’m not an anti-car/bikes-only person but we do need better awareness for all of the rules of the road for cycles and add protected bike lanes. The situation now with a lack of knowledge, blatant violation of stop signs and lights by bicyclists and motorists, and in some cases conflicting and incompatible stop light rules, is complete madness.
Re: nuclear weapon detonation, the implied probability of 9% (I take it source is: https://polymarket.com/event/will-a-nuclear-weapon-detonate-...) might be factoring in the premium for the insurance that participants that predict a detonation are interested in acquiring.

Let's say that the real odds of detonation are 1% and that everyone participating in the market knows and agrees to this. You would expect the implied probability that the market produces to be 1%.

But in practice, a nuclear detonation would be a highly disruptive event where the impact is hard to assess. This creates an asymmetry of interests. If you want to protect yourself financially from such an event, you would pay a premium for it (which in a prediction market implies placing a higher bet on "detonation will happen" than a perfect gambler). If you want to protect yourself from the event _not_ happening, you would also do the same, but no one really does that other than speculators.

Similarly, you can sell tornado insurance to a lot of people, but very few people are interested in insuring that a tornado _will_ happen (maybe concrete bunker architect studios?). So the underlying prediction market would skew towards overestimating the likelihood of tornados.
Where, Riverside Drive? The parks? The vast majority of bike lanes I see either A) do not exist, so bikers are forced to share space with either cars or pedestrians, or B) a narrow lane in the road demarcated by only paint. Plus, bike lanes are often blocked by delivery trucks, taxis, etc, so bikers end up having to share space with cars or pedestrians anyway.
If you've never had an ice maker break on a fridge, then you're a lucky person.

The west side greenway is segregated downtown and in midtown, but joggers and tourists often go in the bike part anyways. There are some pretty clear signs and bikes painted on the ground there, but they get ignored.
