Can you elaborate? I’m not familiar with these. What are the pros/cons?

As for the Apple Card, I’ve been fairly dismissive of most of Apple’s recent products, but this is the most interested I’ve been in an Apple product since the iPhone. It feels like a similar situation: a “device” that seems simpler to use than existing offerings leveraged off of a partnership with a company that has nothing to lose by playing along with Apple’s game. It might not be the best card offering in terms of features, but it seems like a solid choice for the masses.
Where's L. Bob Rife in all of this?
Unless I’m mistaken Lyft came after Uber right? They built a good product but nothing unique other than being “not-Uber.” In that sense you can think of Green and Zimmer as being hired by their investors to produce an alternate Uber. They executed very well against their task and everyone got a nice payday for it.
I'm going to let the pilots decide whether it's reasonable. I don't know anything about flying a 737 and I'd wager that 99% of the people posting here don't either.

If the US pilots unions are okay with it, I'll be okay with it. They haven't crashed any 737 Max yet.
Are people in general not recommending the Dell XPS's anymore?
First time I’m interested too. I hate wearing watches and stuck to an iPhone and MacBook only until now but I’m at a high risk for heart disease. My dad died when he was only 43 from clogged arteries. I have familial high cholesterol, but statins have helped me lower to normal levels. My dad died in 1992 before statins. With statins and ecg on a watch we are all very fortunate to live in the time we do.
It is odd to me how he keeps describing his $500/month insurance as being useless: he is generally in excellent health and his yearly expenditures are low enough that he is always paying down the deductible.

Does he feel car insurance and home insurance are useless since he didn't total his car last year and his house didn't burn down?

He knows this (as he mentions it obliquely) that he could lower his deductible but his costs would go up. Is he complaining that he is on the wrong part of that tradeoff curve? Or does he expect low-cost insurance with a low deductible that covers all of his routine medical expenses?
> Is there any reason why they can’t accept an alternate credit card from the one that secured a reservation?

I did just that 3 weeks ago. Someone made a reservation for me, I used a different card to pick up the car.
I think we're diverging. The mental model of a Rails developers is well formed and if you're a beginner then you can rely on a very strong community for opinions, best practices and conventions to follow. This greatly decreases cognitive load and immensely improves productivity.

When you make a jump to a JS stack (whether client side or server side) you have a lot of options but no best practices or conventions to follow. You have to make a lot of choices which have already been made for you in RoR. Even though SPA frontend dev has settled between React and Vue, you still have to make a lot of decisions. React also bills itself as a view library. You have to make decisions about state management (if needed), routing etc etc. A vast chunk of these decisions are made for you in RoR so that you just work on the app. I think this is what the author was lamenting about.
I don't buy the explanation given in that discussion thread. A quick googling suggests that RSI from keyboards is related to how much pressure you have to exert to move the keys, and the low-key-travel MBPs don't need much pressure to press a key. This really sounds to me like it's just anecdotes and confirmation bias (I got RSI now, it must be due to the new keyboard design, as opposed to just continued use of keyboards over a long period of time coupled with aging!)
Does Docker or Centos or Beanstalk or Kibana mean anything? No, they're just symbols. It's just a name and you have to know what it means. Everything in tech has some stupid name.

You're not missing any part of using serverless by not caring about servers. You have platform constraints to minimize.
That's what a-fib is: unusual rapid heart rhythm.
Are there any quality alternatives for literally just monitoring your heart? I don't like the watch but I want that feature pretty badly.
As a beginner, Rails seems much easier to get from zero to something. So much of the tutorials I’ve seen on react are about dependencies and environment setup. I know React has some big advantages but on smaller teams/projects it’s hard to see the benefit.
For those downvoting me, if you genuinely think that pentalobe screws are bad, can you please explain why someone who doesn't have access to a pentalobe screwdriver has even the slightest business opening up an iPhone?
It feels useless when you know that after paying in $500 a month for decades your insurance could be cancelled for making a claim.
IDK about this. I find it kinda creepy to have my heart beat monitored & sent to a server far away and not under my control. I mean, ad companies already have so much data about me, do they also need to know how my heartbeat reacts to an ad? Does my insurer need to know it? I wonder whether it can detect sex and be used to e.g. track infidelity.

On the other hand, of course it's great to save lives and help you detect possibly harmful conditions. The thing that makes me uneasy is not the idea of a heart tracker watch per se, but the possibility that maybe one day the facebook app wants access or chrome because of WebHeartBeat API or whatever. This trend of constantly increasing amounts of data sources sent to the cloud is sick.
I never liked Rails even when it was hip. Way too much bloat and magic behind the scenes, and also poor performance because of that.

I always preferred Flask, because it gave you a minimal framework, allowing you to cherry pick modules as needed. Sinatra looks similar if your preference is Ruby.

I cannot say that a Node stack is better though. Both Rails and Node are fairly awful, but for entirely different reasons.
I'm surprised nobody has mentioned Logicblox yet [1,2]

I saw some variation of this story around the time it came out:

Grandfather discovers heart condition thanks to children’s museum exhibit

https://kdvr.com/2019/02/21/grandfather-discovers-heart-cond...

I don't think I submitted it to HN. I felt it would be viewed as fluff.

But we have incredible and constantly increasing opportunities to casually check biometrics that previously required serious medical exams and lab work, etc. It's absolutely changing things.
The US Intelligence Community as a whole is under constant demand for perfection. Not every individual unit (I've worked with several, and it varies), but institutionally the executive branch and military leadership applies the pressure of perfection at the top, and that pressure trickles down, skewing data, analysis, and policy making (and policy execution!).

I personally blame Hoover for the state of things, but as a whole, our government is used to control, and complete control relies on complete information. If something is missed because it fell between the cracks in the IC's sampling rate, the executives publicly blame the IC for not informing them, which ends with demands for a higher sampling rate. Look deeply into the causes of our most recent invasion of Iraq, and you'll see this pattern pretty clearly.
The US airlines all purchased some/all of the "optional" safety features that would have made it obvious to the pilots that the system was malfunctioning.
I'm confused by the "systemic weakness" exception for the third case. Obviously I need to research this, but it seems that in many cases, a backdoor is, almost by definition, a systemic weakness. Of course, I wouldn't want to argue that point in front of a judge, but it would be useful to have more clarity around this.
To quote the ever popular HTTParty Ruby library: "When you HTTParty, you must party hard!".
Most of them are useless. What's your goal?
I'm waiting for a chance to try out Crystal/Amber, which is type-checked (not sure how safe?) and can be pre-compiled like Go apps. It looks really close to Rails:

(I couldn't find any code snippets on the official Amber framework page, I hope this is representative.)
Every reliable complex system started as a reliable simple system and evolved.
Yeah, something looks and feels very weird about these pages. The antialiasing behavior on some of the shapes+text is very strange looking, as well as some weird scrolling behavior. Seems very... uncanny, as you say.
Why not buy the cheapest S4 model for around $400 or so and just only do the ECG? Or are you looking for a less expensive option?

The reason is I would suggest the watch is their ECG is tuned quite well.
Bingo. This is the end state of capitalism, a total lack of concern for brand on the part of the companies; a total lack of loyalty and trust on the part of the customer.
This is why I feel like merging Asperger's into Autism was a mistake. When some people say Autism, they mean being slightly non-neurotypical in a way that maybe adds some challenges to the person's life, but is more of a difference than a disability. When other people say Autism they mean severe behavioural and cognitive difficulties and round-the-clock specialist care. Each of these people is speaking from their own experience and yet this one label covers an incredibly wide range of implications.
Imagine a regular sized family of 4, you have to shell out more than $20K/year for the most basic health insurance for your family if you are self employed, $20,000! and you still have to pay for EVERY doctor visit for your kids and regular checkups, and your family deductible is around $10-12K. And every year they send you a new increased quote by 10-15%. There should be some kind of a discount for families, like when you have multiple cars under your insurance your rate barely goes up when you add another one.
His insurance sucks. We don't need to look at a chart to realize that. I have a low deductible and I pay under $100/mo.
Licensed nuclear plant control room operators go through 40 hours of training every 6 week. Generally 5 weeks of operations rotation then 1 week of training, all year, every year. Twenty hours of classroom and 20 hours of simulator training, the week includs a written and simulator exam. Failing either and the operator is taken off shift until his remediation training is complete and exams passed.

If pilots rotated into training time these changes could be addressed in simulators on a scheduled basis the airline could plan for.
Plastic that's been buried in a landfill won't show up in the ocean. Plastic that's been burnt in incinerators won't show up in the ocean. As this story shows, if plastic finds its way into the ocean, it's because people had loaded it onto ships and dropped it there.
Programming Is for Squares
Nasa's Mars Helicopter Completes Flight Tests
I tend to describe my issues with Rails in a nutshell: it felt like everything was optimized for day 0 instead of day 30 or 300.

Devise was the ultimate example of this. `rails generate devise:install`. Instant authentication system with almost zero changes to your code base.

Yet now something as central and important as authentication is implemented outside of your application in some highly abstracted software. To do something as simple as figure out the name of the cookie it sets, you have to either dive into its internals or look at the actual cookie it sets instead of just reading code that should've existed in your code base.

Rails was the first "language" I learned so I was its best case subject. It was able to indoctrinate me in the beauty of metaprogramming and things like that. Yet that still wasn't enough to keep the light from shining through the veneer when working on a real world projects where you just want to know how something works by reading application or glue code, not daisy chaining through a bunch of library code or hoping you cache-hit the library's FAQ so you don't have to deep dive.

There seems to be a lot of "why is there no Rails in {JS,Go,Rust,Clojure,...}" lately and it's no surprise to me why there isn't. The same reason Ember and Meteor never took off to the degree that React did.

There was some sort of "glue code just isn't that bad" renaissance.
Go to a doctor for a physical every year.
I really like the start of your comment. I see that if something bad happens, the politicians shift blame to the Intel community for missing it. Then they put pressure for more complete information from them. Then later, when there's civil outcry over a surveillance state, the politicians shift blame onto the Intel community for being too invasive. Politicians man.
Do you have any code samples for this? Sounds interesting.
I can't lie, I was thinking of switching to the Apple card when it's released. Unfortunately, it's a mastercard :( so no costco gas or shopping and I only carry one credit card in my wallet..
I'm still floored when I read those interest rates. You guys got a Visa Debit? It's a visa, that uses the money you have... Clever isn't it?

When will people understand that buying something now without the money is not freedom? It's not, it's shackles.
When it comes to your heart, you want a false positive rather than a false negative.

This is just basic medical stuff.
Web Notifications Need to Be More Like Blimpie
Static is my hope too.

We started with a Rails project two years ago. It's a bit slow, but dear god we get so much done with it. That being said, having Typescript on the frontend makes it so utterly clear how much better Rails would be with static typing.
While this is great for Afib detection it's its very rare CDC says 2.7-6 Million people[1]. Still great for those people! I still think we need to do much better. High BP and hypertension is way more important to measure since they can be diagnostic in a larger percentage.

My dad is a triple bypass heart patient. ECG and stress tests did diddly squat to detect it, until it was too late and it was diagnosed by a CT Angiogram. I now get CT Angiogram with contrasts every few years just to be safe because of family history.

So I do. But nothing he does touches on this subject, at least I think. Maybe I'm not in the right age group for him to bother. He listens to my heart and checks blood pressure. My sense is that this is just so unlikely given what he does know about my health that he doesn't explore further.
But...most doctors don't give ECGs at physicals?
That’s just it—the way they describe it, they can use it for nefarious schemes, except marketing.
A nuclear power plant failure, in the worst case, is much worse than the worst case pilot error.
bogomipz -- sorry, I didn't see you replied to this. The machine traps to a parity error handler (one for microcode RAM, and a different one for data ram) and prints out a message indicating the error code and the address being read when it was detected.

There are a number of microinstruction formats, and fields aren't always contiguous. Making up an example, say the instruction is "ADD R1,#imm8" to add an 8b immediate to the R1 register. But the 8b immediate value is stored in bits [14:10] and [4:2] of the microword. The straight-forward way would be to write "uint8_t imm = ((instr >> 7) & 0xF8) | ((instr >> 2) & 0x07;" Instead, when the writable control store is written, that quantity is decoded and stored in an 8b aligned predecode field, so getting the value is just "uint8_t imm = instr_struct.imm8;"

The machine is the Wang 2200. There were two architectures: the first used a 20b word in ROM, the second used a writable control store so the BASIC could have bug and feature updates by mailing out floppies.
The point is that inflating the money supply is a tax, just a hidden one spread across all holders of assets denominated in that currency (cash, loans, salaries, ...)

Smaller amounts of "print and spend" inflate less than large amounts, but they do cause inflation, and the wish list is never just healthcare.

Controlling a fiat currency lets you hide some taxation as inflation, but it is no free lunch.
My mistake! Sorry! I think I must have conflated a few different comments in my mind.
Get the monopoly established, then you work on making it profitable. Being the only game in town is more important to them right now.

Is it sustainable? of course not. Does that matter to the people who want ALL of the money, not just some of the money? of course not.
I could never get into Rails because of all the magic. “It just works” doesn’t cut it for me, if I as an engineer, can’t understand exactly what’s going on under the hood.
This is a map of the religion people feel obligated to say they are when asked by someone they don't trust.
"Better a diamond with a flaw than a pebble without." [1]

Are people be better off without the watch altogether if it does not have perfect detection?

Don't let perfection be the enemy of good. I don't think we should hold Apple/the watch accountable for type II errors for similar reasons as to why we have Good Samaritan laws.

It's true that there isn't an official way to use Devise over REST, but then again Devise isn't even the official way to manage auth in Rails apps - it just happens to be the de facto one due to community support. That being said, by using something like devise_token_auth/simple_token_authentication and devise-two-factor you can have a token based auth system with MFA ready in a matter of minutes.
Personally, I don't think there are really any back-end frameworks that have an official way to handle auth as it's always based more on community consensus.
Instead of killing the player character, the game kills you, the player.
A system they weren't told about, weren't trained on. What they have is an "AOA disagree" indicator, among dozens of indicators. There's no reason for them to see it or go looking for it in the example cases of MCAS upset where they're reacting to an urgent situation. The indicator might be useful for a maintenance squawk report.

Ordinarily sensor disagree would give you some idea what could be affected because you've had training to tell you this. Not in the MCAS upset due to faulty AOA sensor case.

Until the reports are complete, I think it's getting out over one's skis to say would would have been obvious to U.S. pilots.
I'm interested in hearing about applications successfully using ActionCable for what and how. It's unclear to me how much use it's getting, or how well it meets actual use cases.
It’s really good at highly dynamic/interactive apps, such as browser versions of asana or slack, or other things where user actions are small but frequent. If you aren’t doing full page reloads and have a lot of changes, it’s much simpler than managing each individual state change in vanilla javascript.

I personally think React’s component model is much nicer than any templating system I’ve used as it supports composition as a first-class feature.

And if done well, yes you get better performance on the frontend. (If done poorly, you don’t.)
While true by the dictionary definition, the commonly-understood colloquial definition of 'censorship' is government censorship.
This is indeed an awesome area that I’ve barely ever considered. If I had to go do another PhD, it might be in this. I’ve seen research about using cell phones to detect drug use (and try to prevent the urge).

What other everyday objects could be utilized? What about my phone’s front facing camera to scan my face looking for muscle twitches or eye issues?
Fuku is puzzling in many ways.

Daiichi was built 10m above sea level in a region where several huge tsunamis had struck in the previous century, including one in 1896 which rose to 38m. The 2011 tsunami: 15m.

Also puzzling: the consequences of opening the containments to relieve H pressures, as against the consequences of letting them explode.

Also puzzling: the coast of Japan has A LOT of offshore winds. Why is importing fossil fuels a better idea than going with wind?

Whatever the source of this mistake, what's certain is that the cleanup cost will be hundreds of wasted billions. The hidden costs will be kept hidden for as long as possible ... a long, long time.
Not sure what you mean by that, but probably not that stack corruption is a necessary evil of any language.

They are supposed to say, "I don't care what the indicator says, I never spilled anything on this laptop".

If the indicator doesn't do what it's supposed to then why would you accept it once? Why would someone accept it 5 times??

As a comment, if the other parts of the laptop can fail it's not unreasonable to think that the moisture indicator could also fail.
The arrogance and ignorance of this post is massive. There is nothing wrong with rails or django or symfony or any other server side rendered web framework, whether it's 2012 or 2019. The author seems to think that somehow react SPAs are the only modern apps. The case against SPAs is still huge and for most use cases, they are the wrong tool for the job. This type of cargo cult, fashionable trend thinking undermines his entire argument and questions his qualifications as an engineer. There's no logical explanation for not using rails or something like it. He's complaining about a problem with literally dozens of proven solutions, including rails, that he's even aware of, and yet refuses. What ever happened to use the best tool for the job rather than what's fashionable and popular in 2019? I would not want such an engineer anywhere near my company, that's for sure. I can't think of a worse trait than knowing the right solution to a problem and deciding to use something else just because "everyone else is doing it." Absolutely bonkers.
Where I'm located, .NET has died years ago. Just Java, Go and C++ now. I guess these things are regional.

Unity is increasing C# popularity, though. So maybe .NET is not going away, at least yet.
I think this is an interesting idea, but it also reminds me of this youtube video https://www.youtube.com/watch?v=760uy8Oa_XM

The lady complains but I think she enjoins it. It's fun to complain and be heard, even if it seams minuscule annoyances to any observer.
If I remember correctly frogs were an early model organism for studying fertilization because their eggs are large. Seems reasonable that would extend to early hormone secretion post-fertilization.
Toilabs. Just started out doing just that.
It's private code. I'm writing a book on this topic and will release once it's done.
O_EXCL and RENAME_NOREPLACE are examples of why you want case insensitivity to be in the kernel. They're atomic operations: if you use O_EXCL, you could get a successful file creation, or you could get EEXIST, but not something in between. But you can't implement a case insensitive version of O_EXCL in userland. As I said, the best you can do is scan first to see whether a conflicting file already exists, but that doesn't help if a conflicting file is created in between the scan and when you create your file.

The kernel is in a better position; since all readers and writers must go through the kernel's filesystem routines, those routines can use mutexes or other concurrency mechanisms (that they need anyway to protect their data structures) to implement higher-level atomic semantics. That's how the kernel implements regular O_EXCL, and it's how it can implement case-insensitive O_EXCL as well, without having to deal with race conditions. In fact it already does that for vfat and other case-insensitive filesystems.

(A FUSE filesystem similarly gatekeeps all accesses and thus can do the job in userspace, but FUSE is slow.)
