It's not that it's particularly useful so much as it's available. The FCC has been clearing spectrum because more spectrum means that carriers can offer faster 5G services. Mid-band spectrum (in the 2.5-6GHz range) is particularly useful because it offers a good combination of range (measured in miles) while still having a decent amount of spectrum available and the possibility of things light higher-order MIMO to offer capacity gains.

Millimeter-wave spectrum (in the 20-50GHz range) has lots of spectrum available, but its range is often in the 50-300 foot range. It's also important to realize that because we're talking about a radius, when we turn that into a circle the difference gets magnified. A 1 mile range means covering 88M square feet. A 100 foot range means covering 31,000 square feet. 53x more range turns into 2,800x more area covered.

Initial 5G networks in the US often used 5-20MHz of low-band spectrum (below 1GHz). This does have some utility as 5G NR is marginally more efficient, even in low-band spectrum. However, deploying with 100-200MHz of mid-band spectrum offers the kind of huge gains that offer 10x (or even more) data speeds.

There isn't really a lot of spectrum that hasn't been allocated so it's often a game of figuring out who you can move for the least cost and most benefit. They chose to move C-Band satellite operators (at a cost of billions). Previously, the FCC freed up spectrum in the 600MHz range by having TV broadcasters relocate from UHF channels above 37 to lower channels.

What I grasp is roughly the following, we know, that you could construct a scalar field, part of a spacetime that solves relativity, that would show almost no effect on a weak gravity environment (it's mostly undetectable, unless close to a massive object). But in massive environments, we could in principle detect the effects of a non-trivial field (i.e. make predictions, and try to observe them).

Essentially, build a theory (perturb the theory), and make a testable prediction that works on the large scale, but would be hard or impossible to observe on a weak gravity environment (for some definition of weak, I think they mean something less massive than a star).

They ask whether or not you can do something like this with a more complex, vector field (i.e. a new force/particle).

It's all very theoretical.

But it may give an avenue to find new physics, maybe even explain dark matter/energy.

Tuples are a great example that I might not have thought of -- you practically "define" your own value types all the time. Also, all enum types are value types. And there are lots and lots of very commonly used value types in the base class library: DateTime, TimeSpan, Guid, CancellationToken. Programmers have to be familiar with their semantics.

The altimeters are used by the auto pilot, especially in bad weather. In the cockpit the altimeter would probably give obviously false readings, but in that case the plane can't land and has to divert. It is possible the interference could cause the radar to give a plausible but incorrect reading, but this is a worst case and to my (limited!) understanding, remote possibility.

I don't like their phones, their TV screens are too blue-tinted for my eyes, and their appliances are packed full of fancy features that few appliance repair centers are competent at diagnosing and repairing, and every samsung appliance I have ever had has had a major fault within 3-5 years that ultimately led to the appliance being replaced.

I may be old school but I don't think its wrong of me to expect at least a decade out of an appliance, especially when you go mid-tier or higher. Samsung is priced at mid-tier or higher, where is the commensurate reliability?

They do make good SSDs though, I'll give them that.

The 2008 crash showed that most of those signals are highly manipulated. Bond ratings can be colluded on. Just a few short years later most of the dust settled on that, it happened again with the LIBOR rate. Traditional markets can be systematically manipulated when the fiduciaries don't act in a very fiduciary manner. (It keeps happening!)
This seems like Boeing trying to get the government to cover their butt because they did shoddy work on the altimeters. They were allocated spectrum for the equipment and then built a system that monopolized frequencies well outside of the allocated spectrum.

I completely agree that Boeing needs to issue a recall order on all affected hardware and provide a fix. This should be painful, it is basically punishment for trying to cut corners on safety equipment.
That sounds good, particularly the "split weight distribution" but never-the-less I'm concerned about the weight of your unit.

I've seen designs that split off the main battery pack for added flexibility and weight management. The Vive Flow has other issues that will probably hold it back, but the way they handle the battery is great.

Asking this question in good faith and in the interest of a productive discussion: Can someone give me their reasoning for why to use this over just paying for YouTube premium? They're providing a service that you value and spend enough time on to warrant looking for a way to not have to view ads, and if everyone were to start using Vanced overnight, YouTube wouldn't be able to justify staying up indefinitely. It feels heavy on negative externalities.

Congrats on the launch! Two questions:

- How does this deal with specifics of the query languages of the different data stores? I'm not an expert with Snowflake, but I suppose it supports specific querying capabilities not found in Postgres' SQL dialect. How are those exposed to Hydra users?

- I'm confused by "As soon as transactions are committed in Postgres, they are accessible for analytics in real-time" vs. "Recently committed transactions are moved from Postgres to Snowflake in near real-time". Is data propagated to Snowflake synchronously or asynchronously? I.e. is it guaranteed that data can be queries from Snowflake right the next moment after a transaction has been committed (as suggested by the former) or not (as suggested by the latter)?

Disclaimer: I work on Debezium, another solution people use for propagating data from different databases (including Postgres) into different data sinks (including Snowflake)

I'm prepared to be wrong. It happens. All the time.

Being wrong is the essence of being a scientist. We call it "hypothesis revision". People aren't always good at letting go of dearly-held truths -- and I am a person -- but I consider it a failing, not a point of pride.

So yeah, I could be Just Plain Wrong. But I have, at least, tried really, really hard to take that possibility into account. It's not impossible that I've failed, but neither will I accept the argument (which I have heard many times) that I have to give the possibility equal weight solely on the grounds that somebody else wants me to, and their ignorance on the topic is equal to the overwhelming number of actual scientists who agree with me.

I cannot prove, of course, that I am willing. But I am at least willing to say that I'm willing, and give what evidence I can that I'm sincere about that. I do not believe that to be true of those who will continue to tout ivermectin despite the linked article, on top of so many other articles.

Calcite is definitely some cool tech. I can see why it would be attractive for bigger teams, but it seems like a big lift for smaller teams. Our goal is to make it easy for devs already familiar with Postgres to be able to use add databases without learning new tools or adding software... besides adding Hydra, of course!

> The western alliance has not only rebuffed Russia, it has expanded eastwards against promises made and thus provoked the current situation in Ukraine.

Every country is free to join NATO if they want, Russia has no say in it. And the reason why most Russia neighbors want to is because Russia is a bully, and NATO can protect them from being bullied.

> What would the US do if the soviets were to expand into Mexiko? Or... Cuba? We know how that went.

Well, for one the US did not attack Cuba... Also, Soviet Union was aggressor side for the whole duration of Cold War, that move was just prelude to further aggression against the West.

> If the mission of NATO was to secure peace, why would they reject Russia

Because the best way to secure peace is to keep Russia at bay.

> Russia as a white-majority christian country shares many values and culture with the others.

LOL, no. Russia does not share western values, such as democracy, freedom of speech or other human rights. They do not belong in Europe, they belong in Asia.
I kind of doubt it. The number of employees (players) in the NFL are a much lower size. Each organization is aware of virtually all the potential candidates. Then is somewhat easy to identify the talent due to stanrdized stats and the fact that much of their past performance has been filmed. Sure, some subjective stuff comes into play around potential and stuff.

In IT, it seems like it's all subjective. If it isn't subjective data, then it's not very meaningful and could be gamed (PRs, lines of code, etc).

Funny you mention that. I was this >< close to preempting your comment by mentioning him but figured I'd give you the benefit of the doubt.

Ask yourself, why do you even know Till's name? Why did Till's killing spark national outrage when 20yr later that would have gotten barely a peep out of people? Because times changed and that kind of behavior was no longer excusable.

>but I think living in a community where you could be brutally killed for any or no reason...

Till was killed for violating social norms (that he presumably was not sufficiently aware of). His death was no different than that of a peasant 1000yr earlier killed for bad mouthing a local lord. It's tragic. But it wasn't without reason, though we may think the reason flimsy and disagreeable.

And this time I am going to head off the inevitable reply by pointing out that I am not defending or justifying Till's killers, just explaining the context.

We haven't finalized on the mmWave yet, but there's standards for human body exposure that we will of course meet. IEC 62311, ICNIRP guidelines, and so on.

The mmWave transmitter is directional, and the basic restrictions for local exposure in ICNIRP for the general public is at 20W/m2. The transmitter EIRP is 15dBm, so you'd need to put the entire transmitter's EIRP into a 4cm * 4cm target to exceed those.

Automakers argue that independent shops can already get the data they need, with permission — but making it automatically accessible by third parties is dangerous.

Yeah, this is just further BS in a long line of BS. This continuing quest to build vehicles that cannot be serviced by anybody but a dealer is just a tactic to make more money off the misery of customers. I dearly wish they just banned the sale of any auto that couldn't comply. We honestly need to deal with this company throws a hissy-fit culture (e.g. Apple and the App Store) every time society says it wants all companies in a sector to act in a certain way. This rent seeking is just getting out of hand.

The Boeing 737 design was introduced 50+ years ago and is still used (albeit not in 50 year old planes) today in a multitude of airlines for passenger travel.

That said the 737 MAX fuckup is something that neither Boeing, or the many worldwide air travel regulatory institutions should be forgiven for. But that doesn't make the 737 design itself bad. That particular iteration, due to Boeing's attempt undertake Airbus and falsely sell the planes to airlines as a drop in replacement with zero extra training needed unfortunately resulted in deadly crashes. The people that decided on that should be charged on the deaths that occured because of their greediness.
Totally agree. I love Cloudflare. I recommend it even for small businesses. It's easy to use and scales beautifully.

The article says:

> My issue arose when I realized that they remove your SSL certificate, then use their own. Cloudflare is a big MITM service.

All you have to do is change one setting in the DNS record (from Proxied to DNS Only) and you totally bypass the Cloudflare reverse proxy for that resource. So you can use your own SSL cert (if that's your thing). And you can still use Cloudflare access/zero trust with that resource. And solid and free DNS service. And cheap domain renewals.

Cloudflare is a great set of tools for many use cases.

I don't have a problem with the price - I have a problem with being sure what I'd be getting for that money. If it was guaranteed to live up to the claims that are being made then it's in the ballpark of a good laptop, which I have no problem dropping all sorts of money on. This device has several potential problems though, that can render it completely unusable rather than a laptop that mostly works fine except for a nit or two:
- If it's too heavy/uncomfortable, you can't use it for long enough to warrant switching your compute medium to VR
- If the battery doesn't last long enough, then you're tethered to a wall outlet.
- If the display has distortion or artifacts, the eyestrain may render it unusable over time.

Some of which can be addressed by being able to try before you buy, and the rest will come out in the product reviews....but right now there are no product reviews, and signing up for a preorder at this price is taking a lot on faith.

I wish this team all the success in the world, but I'll probably wait for V2.
