That is interesting. I haven't used any of the Apple watches so I can't speak to the effectiveness of its HRV calculations for me. One of the Oura C-level guys spoke in a podcast that doing those kinds of calculations isn't as reliable because of differences in vascularity / fit on the wrist vs a finger but who knows how true that is. Maybe it's true only for the existing monitoring tech?

I've seen my average vary from 10-50 and HRV max from 50-140 depending on sickness, exercise routine, hydration, drug use, etc. The quality of that average is interesting to observe as well, ie two nights' average of 40 can look very different depending on the peaks and valleys.

It is challenging though to suss out what effects various things have. It requires a whole lot of normality in my lifestyle so as to limit the number of variables as best I can.

I really like "matrices are the coordinate form of linear transforms." In the LA class I took the professor made a pretty big deal out of that, first by defining "lexicographic matrix basis" so he could write out matrices as vectors and then talking about mapping between the three different ideas.

There's still stuff he said that I'm unpacking today... that was a dense class.

Totally agree! Overwatch is often criticized for the pro meta "infecting" regular play, because low/mid level players will find themselves pressured by their teammates to play heroes that are meta at the pro level, even though pro strategies are only meta when they're being executed at the highest level of play.

Tbh outside of maybe a sandboxing aspect, UWP made zero sense to me when Windows Phone fully died. Before that, the ability to have one codebase target both desktop and mobile seemed interesting at least, but now, it would seem that there are only a tiny of handful of applications that could be useful as universal between the remaining UWP targets (desktop, xbox, IoT, whatever else)

Basically every household should already have, regardless of the origin of the disaster: 1 month of clean drinking water or reliable (tested) filtration devices and a impure water source (local streams likely to have various bacteria that will make you sick). 1 month of food that requires minimum water and fuel to cook (quick oats > slow cook oats). Enough fuel to cook that food (most of your food should not require cooking). A reliable camping stove that you have already tested. Plenty of ways to start a fire/stove. Warm clothes, blankets, med kit, sleeping bags. Soap.

I've lived for 30 days in alaska on a glacier with only what I could carry in a large pack; water and fuel were the largest by weight, sleeping bag/tent/clothes were the largest by volume. By the end, campers had devolved into small groups of people who didn't share food.

Netflix had no issues letting people go who just weren't needed anymore. They might have been very good, just not needed.

For example when we moved from the datacenter to AWS, everyone who dealt with datacenter ops was given the option to learn AWS or get a generous severance package. Also, when we moved from relational databases to Key/Value, the DBAs were asked if they wanted to learn to managed Key/Value stores instead, or if they wanted to look for new jobs.

While technically true, most GA piston airplanes have liability limits of $1MM (sometimes $2MM, rarely more) and often per-passenger [or worse, per-person] sub-limits of $100K, so there's a cap on the liability payment the insurance company is signing up for.

The iPhone.

That's a little generous, but the rise of smartphones (and their data connections) brought widgets and gadgets to the handheld, with-you-everywhere device and a little advertising on top didn't hurt. The motivated persons who developed the gadgets for free or donation moved to apps because it worked better for them _and_ they were able to get some extra money on top.

For sure there is an effect on Reddit and other places where someone will post a question such as, "I'm having trouble with my Calc class, what is a good book?" and people seriously answer Calculus on Manifolds.

Now, CoM is a classic, a real great book, but it is useful only to people who have reached a certain level of mathematical maturity. That, presumably, is not the questioner.

A version of this is that I also see people who write, "I didn't understand this topic when I took the course but now years later, I see it is all actually very easy."

(I call this Second Book Syndrome because I don't know of a common name for it. I understand this to be what Zen people mean by the "Gateless Gate," that after struggling with something at great length a person can come to see that there is no real difficulty. But I've never heard anyone else apply that name to this phenomenon and I'm not Zen trained so I'm not sure that is right either.)
Who the fuck downvoted this post, and what is your issue, asswipe? Seriously. A person can't post a fucking thing on this forum without some pissant downvoting it. Sometimes in mere seconds after posting. Makes one wonder how many downvoting bots are running loose on this forum.
I'm sorry, but people who claim "they've made the switch" just don't get it.

Agreed. At 46, and having been a night-owl pretty much my entire life, I'm skeptical that you can just "switch" to another mode. Maybe you can, through very conscious and focused effort, manage to adapt to what appears to be a "morning person" lifestyle; but I suspect that people who do that are ultimately just faking it.

That said, I've never looked at being a night-owl as something that needed to be "fixed" or something that I'd want to change.

Specifically for screenshot markup, I recommend using flameshot (https://flameshot.js.org/#/). It allows you to markup the screenshot right as you take it.
> More prevalent end-to-end encryption is a good thing.

I agree -- I am not arguing against more prevalent e2e crypto at all.

> If an encrypted DNS scheme is blockable by you, it's blockable by an ISP.

Perhaps, but it's also possible (unless you're using DoH) to evade those blocks without a great deal of difficulty.

I'm not arguing with anything you've said here, really. I'm just pointing out that the way that DoH works means that there is a security hole that makes it very easy for marketers and other spies to evade your protections against them.

So yes, DoH brings some security gains. But at the same time, it also brings some security losses. Whether that tradeoff is good for you should be a decision you can make -- but again, due to the way DoH works, you no longer have that choice available to you without going to extreme measures like I have.
I'm not a die-hard follower of Apple developer news, but it being released in June 2019 made it feel at least somewhat mature to try out. There's nothing AFAICS on the SwiftUI documention mentioning that it's not quite production ready.

> Or are react and react-native completely different beasts?

The language is the same, and the core concepts are the same, but the SDK's are completely different. You are using different build tools, different API's, different platforms. It's not HTML-in-JS. So a React developer is not going to be fluent in react-native by default.

Look, ma! I'm driving on a track with no hands! What a joke.
"Legally" is dubious. Intercepting any private wire communication is a clear violation of federal law (e.g. 18 U.S. Code § 2511), and a violation of the law in many states (e.g. CA PC 631).

Unfortunately, the US government is one of the larger users of ISP surveillance activities, benefiting through the purchase of private data as well as using administrative subpoena to obtain the data collected by ISPs without due process or meaningful oversight.

This creates a conflict of interest which I believe is preventing the US from zealously enforcing existing criminal law which would be otherwise sufficient to significantly reduce surveillance by communications providers.

> Even so, I don't even think such an API should exist.

There is no "exfiltrate all my history" in the webextension APIs. What exists are two distinct and reasonable components.

A) accessing browsing history/current tabs/network requests¹. all things required for extensions to work
B) ability to make generic network requets

Combining these two can be used to exfiltrate data. But that does not mean that any particular extension that has access to both will also exfiltrate private data. Thus a blanket warning would be overly broad and anything more targeted would require manual sourcecode inspection.

¹ Those require separate permissions, but for the purpose of the discussion they can all be used to harvest data
Disintegration (2019)
Yeah, in fact, on our 3, it's pretty annoying. I virtually always have my hands on the wheel when autopilot is on, and it still seems like it nags me every 15 seconds to apply turning force to the wheel. Even when I think i'm applying enough force. Then sometimes you apply too much and it disengages.

I can't say I use it all that much, or like it all that much, but I do so occasionally. Just got home from a roadtrip last night. Frankly, because I'm watching where I'm going anyway, I feel the traffic aware cruise control (available on lots of other cars as well) is the best part. If you're looking down the road the steering input from your body is basically automatic anyway. And it's smoother than autopilot.

(if you're not looking where you're going, hopefully you're not in the driver's seat)
Most hardware companies suck at making software. If AWS can get a decent traction, maybe they will replace their custom crap with better engineering software, which would be a win.

Also a win for AWS, of course, as this would make it easier to use their services.
Totally, but when using AI to control wipers its sad they cant be bothered to respond to safety regulators when they could be leaders in this tech by simply adding a camera system that monitors the driver like some other automakers are experimenting with implementing.

Same issue. I am resident in Lithuania (but I am from the UK originally). When I view youtube (on a firefox browser I have never logged in to youtube with) I get the same message...
Actually a rather famous example of your point are the Feynman lectures. They are often hailed as a great, "easy" and intuitive explanation of physics. However, supposedly at the time, the undergrad students Feyman was teaching did not think their were all the rage. It was actually the grad students who retook the material and really enjoyed them. To support your point I think sometimes it is really necessary to have been exposed to the material and been able to grasp some part of it, then you are open to these type of explanations which really lift you over the hurdle of the things that you didn't quite get before.
Ideally this would be a standard component of home routers, especially some easy wireguard QR-code setup. But yes, until this happens it's something for more tech-savy users.
I like the clear statement that the components are memory optimized (as opposed to execution-time optimized). Their target audience are device developers (and of course users of those devices), they're making good steps towards that, but of course both should be wary of how auditable the toolkit is, and most importantly can it be abused by Amazon

But nobody could view your web page unless they had downloaded the appropriate scripting language.

That made it appropriate for intranet applications, but not the internet.
Indeed they do, which is why that's not a sufficient defense all by itself.

The next level up is to block the DNS lookups that happen when the spies are trying to find their servers. That's what DoH prevents.
I thought the static PNG was just fine, personally. What would an animated GIF show here, the time changing every 60 seconds? Animated product showcases are just annoying to me because I can't study any particular scene long enough to see everything.
He's suggesting he ought to be able to use imperative Swift control flow constructs in the declarative SwiftUI DSL. I suppose I can't really know exactly what his confusion is, but that just doesn't make sense.
> 1) Growing density - you use a lot less square footage by growing up!

Yes, but all of that square footage is inside the building, which cost money to construct and operate, in addition to capital costs of constructing the multi-tiered farm and wiring it with LEDs

> 2) Can grow anywhere

Yes...anywhere...inside a heated building. Even if the LEDs used provide some degree of heating, some sort of HVAC to regulate temperatures must still be employed. I'd imagine you wouldn't use an unheated warehouse in Canada during winter.

> 3) The ability to very carefully fine tune the end product due to a large number of controllable inputs into the growing process

Probably the only real advantage. It also makes ramping up to demand somewhat easier, since the growth time is shorter.

However, make no mistake - so far these are low calorie greens at a luxury price.

>Before enabling Autopilot, you must agree to “keep your hands on the steering wheel at all times” and to always “maintain control and responsibility for your car.” Once engaged, if insufficient torque is applied, Autopilot will also deliver an escalating series of visual and audio warnings, reminding you to place your hands on the wheel if insufficient torque is applied. If you repeatedly ignore these warnings, you will be locked out from using Autopilot during that trip.
IIRC after the 2nd notification, it will slow down and disengage autopilot with no ability to re-enable it until you park the car. Proactively ignoring it isn't really an option.
Isn't this basically SRGAN?

Edit: sorry I guess since there's an explicit rotation module it's closer to SRGAN+deformable convolutions.

I started with the full version of MacScheme about the same time that I started with CCL. I loved them both, and at first I liked MacScheme better because Scheme was a smaller, simpler language, and easier to learn. CCL won me over in the end because it was just so much easier to get things done.

Later on, John Ulrich, who owned Lightship Software, the publisher of MacScheme, came to work at Apple and became a friend and colleague. I continued to use MacScheme off and on for years.

I’ve happily paid for Lispworks licenses many times now, but even Lispworks isn’t a good solution for everything I want to use Lisp for. A modern version of CCL’s graphical environment would still be a nicer place for newbies to start. You could even use Lispworks to build a product like that, if the license didn’t prevent it. (Lispworks doesn’t allow their product to be used to make Lisp development systems, which is understandable. They’re a small company who don’t want to put themselves out of business by enabling a customer to give their Crown Jewels away.)

Totally disagree. First principle thinking is a clearer formulation of what the author wanted to achieve with the meta concept. For example in the marketing example where the meta dictates movement from adsense to xyz platforms you can also get there by first principles, which is finding the most cost effective way to reach the audience.

When you're thinking from first principles you are not disregarding the current conditions, including constraints, you are just not allowing yourself to be a lazy and are constantly reevaluating the situation from base. Many people love to talk meta but they end up with a hazy understanding of fundamentals and end up behind the curve, very detrimental. First principle thinking just avoids these issues.

BTW. Games are not perfectly analogous to IRL. Games can sometimes be (imo poorly) designed to function completely based on a fluctuating rps system that forces a meta, where if everyone goes rock you'll have the highest percentages going paper. IRL doesn't really work that way. Pikemen beats cavalry, cavalry beats swordsmen and swordsmen beats pikemen, but guns beat all 3 and it's completely OP.
That's not a good counterargument. Why you ask? Because that's something that OS vendors could easily and trivially deploy with only minimal effort.

For example on Linux you could do this with running a localhost instance of unbound, and having a DHCP client hook script updating unbound's configuration for domain specific authorative DNS servers based on the DHCP options for nameserver and domain name.

Just put that as out-of-the-box setup into default Linux distributions' installation: Not only does this greatly enhance privacy. It also prevents enterprise information leakage, and every program on the system is going to benefit from it. Not just the browser.

DoH is a clusterfuck of stupid. There's not one single redeeming quality about it. Everything positive it promises to do has been already solved in a far better manner by earlier developments. And it comes with the penality of concentration of failure points.

In the best case scenario it doesn't impair your privacy.

In the worst case scenario, all the DoH resolver operators in the U.S. will get FISA court orders – including a gag order – to install boxes helpfully provided by some three-letter-agency that monitor all incoming and outgoing traffic of their resolvers; getting the DNS queries/responses in the clear would be nice, but they don't really need it, for the resolvers provide some nicely observable traffic hub on where it's super easy to time correlate outgoing DNS resolver queries to incoming DoH requests.

And don't even believe that DoH requests would be indistinguishable from "regular" HTTPS traffic! Unless you're running into an DNS record that's been overloaded with everything DNSSEC offers the bandwidth requirements of DNS are fairly balanced in both directions. Plus, the amount of data transferred via DoH is more or less the net size of the final DNS query and request combined. So either you pad DoH for the worst case scenario size, or you have a pretty well readable side channel.

No matter from which angle you look at it, DoH makes no fucking sense whatsoever. It's just stupid, if not malicious.
