So I started having premature ventricular contractions a couple of years ago, and had a lot of anxiety around it — I made multiple emergency room visits and trips to the cardiologists because I was convinced that when they were giving me ecgs, they weren’t getting it when I was having a severe problem and were missing a-fib(which runs in my family)

They eventually told me to get a Kardia so I could check it whenever I wanted to.

After a few weeks of checking every time I thought something was going on and periodically sending the worst examples to their analysts, I realized it was only ever pvcs, and it dramatically lowered my stress levels and made the episodes much less severe and shorter lasting. It also helped me figure out my triggers (caffeine) and helped me realize that going on a brisk walk for 15 minutes pretty much always stops them.

I wouldn’t say the Kardia saved my life or made me healthier, but it absolutely helped me get a handle emotionally on what was going on with my heart and improved my quality of life. I don’t carry it around any more, but I definitely think it’s worth getting (or the new watch) if you have palpitations and want to get a better idea of what’s going on.

Focus less on your own problems and pay attention to the problems that other people have. Especially problems where they've come up with really hacky workarounds -- think Excel spreadsheets, weird approval/email chains, manual import/exporting from one system to another, etc. All good signs that there's something to be improved, and that it's enough of a problem to put effort into.

Couple of other thoughts -- your problems are likely not to be technical. They're going to be obtaining domain knowledge, marketing, and supporting your product.

I'll second the recommendation on "Start Small, Stay Small". Also Eric Reis' "Lean Startup" and 37 Signals "Getting Real". The latter two were really helpful in getting my most successful project out the door and making money.

I'd have to agree. For mental health it's much easier, though I do think you learn a lot about your grit in accomplishing a goal when you commit to Ramen for X time.
Not so “absurd” - you may be missing some context.

A 12-lead ecg can diagnose whether you have a-fib at the time of the ecg. The question for the doctor is whether you may have “paroxysmal” ie intermittent a-fib. So what if the Apple Watch said ‘a-fib’, but the 12-lead is negative. Most doctors are probably going to end up ordering a holter- monitor, to monitor the patient’s rhythm over 24-72 hours. Some proportion of those patients may have very short runs of a-fib, and would likely have remained blissfully ignorant (and well) without the Apple Watch. Instead, they may well end up anti-coagulated, because if that patient is not anticoagulated and gets a stroke later ( which may or may not be due to a-fib), the doctor is going to get sued. Whereas if the doc starts the patient on anticoagulants, and tells the patient that, “ there’s a risk of bleeding, but...”, that is much less likely to end up in a lawsuit.
Spreadsheets are pretty good for using when exploring the execution of an algorithm or computation graph. You can basically book keep every step of an execution.

Efficiencies or lack of it is visible in the spreadsheet in a very concrete way. How many used cells are there, how many “steps” or rows is required to finish a computation and how many times are cells addressed clearly relates to time and space complexity of an algorithm.
Testers are great.

Sunk cost refers to whatever resources have already been spent. Where it becomes a fallacy is thinking along the lines of But I’ve already invested this much money or You know, I’ve been working on it for all these years, so I CAN’T quit now.

What we’ve paid into it is gone — a sunk cost — and what matters is how much additional investment from where we stand now will be required to complete the goal and whether that cost will be worth it when considered against other opportunities for the same time, money, and attention.

In some sense, we start at even every day.
> I emailed Souza one last question: If he were asked by a future president to photograph the administration, would he use an iPhone for official photos or still rely on his DSLR?

> “DSLR,” he wrote back, perhaps crushing a few Apple dreams, “though [I] would still use iPhone for some Instagram posts as I did during the Obama administration.”

I don’t see why people think this will ever change. iPhones (and other advanced smartphone cameras) will always be getting better, but I doubt they’ll ever truly surpass the quality of a dSLR. The laws of physics in the larger camera will trump until we get much more advanced in image processing (and we’ve come a long way already).
Even if "tests" (omg no!) are ordered, they're not going to jump directly to invasive procedures like biopsies or catherization (have had both!$. They're going to do exactly what you've described as a "lowly emt" - thank you for posting this.

Agree except for the 2x part, Dvorak has a deep, slow, gravelly delivery that does not lend well to artificial acceleration.

Also the audio production on the show is absolutely top notch for being done by one dude, the co-host, co-inventor of podcasting, and former MTV VJ, Adam Curry.

Plus the “morning zoo” bit is just a hilarious ruse; don’t let the “light tone” distract too much from the serious media deconstruction happening.

I am curious to know what you find limiting about the Racket GUI. There have been some interesting[1] things[2] being developed with it recently. I have been able to use it to write a stock trading simulator[3] with price charts.

The knowledge is freely available, here's Dan Licata giving an introduction to Dependent Types for functional programmers https://youtu.be/LXvP1A97oAM

Even though watching that, I probably think I understand Dependent Types then I'll read the Little Typer and discover my intuition was wrong like when I read the Seasoned Schemer and thought I already knew everything there was to know about the concept of higher order functions.
I don't think people are trying to subvert constructive discussion, rather, people have a low bar for what they consider constructive for certain subjects.
Quite a cursory "review". I'd recommend

1) updating the meta-analysis of therapeutic RCTs with modern ones, as they're progressively more common

2) Reading more on "folk wisdom" re: supplements

3) Noticing David Pearce and Matthew Bragott.

Some info regarding possible harms of prostate cancer screening:
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5485506/

Relevant snippet:
‘The potential gains of screening are opposed by reduced QoL related to diagnostic biopsies, burdensome cancer treatment, including radical prostatectomy (RP), radiotherapy (RT), and androgen deprivation therapy (ADT), and the frequent long-term treatment-related adverse events, including erectile dysfunction (ED), urinary incontinence (UI) and bowel dysfunction (BD) [12–14]. In addition, RP has a small risk of peri-operative death [12, 13].

Finally, since a substantial fraction of PCas shows late onset and slow progression, overdiagnosis and overtreatment are common consequences of screening, especially when it is performed repeatedly or in men with relatively short remaining life expectancy due to age or life-shortening co-morbidity. Overdiagnosis and overtreatment are difficult to assess in empirical studies, because it would require a lifelong follow-up of men randomized to no screening and various screening options in a study without migration bias.“
No, I'm saying the less impedance mismatch we have with the real physical world the easier things will be to work and make scale beyond earth (we will need a network that can scale to mars, for example, soonish). Fundamentally, we are limited by the laws of physics, so it is beneficial to understand them.

We build abstractions because they are useful, but we also often build the wrong abstractions - this is the entire history of science - building better abstractions. Simpler abstractions are great, but they can limit you. We can build all kinds of wonderful machinery with just classical physics, but if you want the modern world with GPS etc. you need relativity to make it work. All the databases based on truetime are great and marvels of engineering, but they won't be able to scale to even a second planet (getting a GPS equivalent to work across two planets is orders of magnitude harder than the earth one, not to mention the latency).

I'm not condoning your idea of a database that explicitly uses frames, but rather something based on more physical foundations like cause-and-effect. As I mentioned, I think vector clocks satisfy this. But maybe there are other better alternatives.

I'm fully aware of the physics (I have a MPhys, and DPhil in Particle Physics from Oxford).

I know many who made it a life long career. It will see me through to retirement as I still love coding as much as I first learned it 35 years ago. I guess your experience is maybe in another part of the world; many of my eu colleagues and even most of my chinese collagues do not really have those experiences: we make (far) more than plumbers, do not get called out to fix things outside hours and do not have that insane feeling about our jobs. I only get that dreaded feeling reading HN or Reddit about how people need to take uppers to stay awake and have no weekends or vacations, or about the latest language or framework we have to use now (I actually try them all, but that is more of a hobby). But then I get back to work on stable dev stuff we have used for 10+ years and it is all good. In the C/ASM but even C# world, very little changes and you basically do not have to ‘keep up’ if you do not want to (I do, but again, this is also my hobby). Newer things hardly ever help with productivity. And a lot of new things (like daily standups) really are counter productive imho.

Another anecdotal point; we are rolling a new app; the lead tech is 64 y/o and uses React Native and Node (different company than the above so different tech choices; not my choice). He does the app and the API almost all by himself (I do code reviews on them). He gets paid well, works from home and is fast.
On a more mundane level, IBM was full of older techies and programmers. Until more recently, anyway. In my mid-thirties there I felt like a youngster.

Do we have any evidence that these devices lead to long lasting changes? We know that fitbit doesn't.

Yes, they certainly could, but this change doesn't change that at all.
Start a sandbox of some sort, some kind of (digital) file to collect things in.

Collect stories and examples of successful side projects that resonate with you. (You can start by searching HN. This gets talked about a fair amount here.)

Also, collect your ideas and start fleshing them out.

Also, collect information on how small side projects get monetized.
Thank you! This weird meme that programming is hard so lets just half ass things with some saas products glued together with some bird shit and bash (“bash is not code amirite?”) needs to die already.
What's up with all the Excel hacks these days?
Everything here is completely consistent with what Musk has been saying from day one - he wants to open up Mars to humanity, not to colonize it by himself.

As for BFR, so sure, they found some extra uses after reviewing newest design. They have to earn the money for the Mars mission. But the story has been completely transparent from day one - SpaceX is means to an end, to get people to Mars. All their developments - from reusable launches to BFR - are directly in line with this goal. If Musk was in for the money, there are many easier ways for a person with his resources to multiply their wealth.

When you see a group of people that claim to pursue a particular goal, and then spend a decade doing exactly that, you should consider giving them the benefit of the doubt and assume they might be actually honest about it.
Is there a way to download Netflix videos too? My reason is I just can't watch anything at less than 1.5X speed nowadays and Netflix has no such option on mobile (there is a chrome extension though). Any ideas how to do either (dl or increase playback speed on mobile)
- good solutions are abandoned by no reason other than lack of momentum/popularity

- there's a sweet spot between "new, cool but unproven" and "boring but works" and it is different each time

- find the right level of abstraction to work with. Too high and you'll lose flexibly, too low and you're doing work you shouldn't.

- cut the crap and don't waste time with what you don't need. Focus on the product and on shipping the product. Your customers don't care about the latest js lib unless your product is significantly better than the competition for using it.
> > We don’t see, hear, smell, touch, or taste time. And yet we somehow measure it.
> you can either make the software meet some greater threshold

That will, on the other hand, increase false negatives. I think that will defeat the whole purpose of putting the sensor in the watch.

> medicine hasn't studied whether or not healthy hearts are regularly doing this because sensors were inconvenient previously

Medicine has studied this. It is just that this specific kind of diagnosis is subjective and there are a lot of debate.

The main point, from what I understood, the author is arguing is that the one-lead EEG of the Apple watch is prone to higher false positives, and users should take it with a grain of salt.
What were they thinking? That most people wouldn't know or understand the implications over centralizing all things to better collect information. For Google, they turned an old adage into becoming one of the wealthiest companies in the world with the full understanding that besides government regulations, nothing's stopping them.

"Knowledge is power. Information is power. The secreting or hoarding of knowledge or information may be an act of tyranny camouflaged as humility."
--Robin Morgan
The most important thing I have used constantly in my decades of programming: learn the skill of negotiating and specifically get good at saying "no". You will be a far happier programmer and the people you work with will be happier.
I must agree with the potential harm of increased false positives but I am not sure if this is the real issue here. In a short period of time, it is impossible to accurately analyze heart trends to find AFib. I mean, people might feel that everything is okay when it's not (false negatives ARE problematic), which can be only determined in full 24h+ / 12-lead ECG scan. However, 20-30s ECG monitoring is still adequate to gather information about some of the disabilities of the user's heart (for example, if any ventricle is damaged).

When we were bootstrapping with a similar idea as Apple Watch at Aidlab, all cardiologist were looking at us like we were crazy. Well, seems we were talking with wrong doctors, and we should go straight to Dr. Ivor Benjamin.

A friend of mine shared his strategy with me: find some big uninteresting data set from the government or whatever, figure out some way to make it interesting for regular people, and build a nice interface to it.

For instance, turning old real estate and immigration records into an ancestry site.

Monetizing it is still an issue...
Especially if it's meant to be an educational and in any case non-realtime encoder, intrinsics are not really necessary and make the code less portable.

I also wonder how much the compiler can do autovectorisation on code like this --- it's pretty much exactly the type of code that autovectorisation is intended for.

Edit: I noticed in the benchmark that it compressed the 10s foreman.cif (demo video) in half a second, so it's already 20x faster than realtime on that small resolution.
Utter hogwash. The author's mistake, often made by physicians when presented with technology that gives consumers more information, is that consumer knowledge and attitudes remain static.

In fact, while this may at first lead to a bunch of hypochondriac-like behaviors, people's fascination with themselves will quickly teach them to not be alarmed.
It has very limited support for H264 advanced profiles that are usually used, which is a down side. I was honestly surprised about the lack of a good decode library.
Feel free to counter my statement with actual arguments, I’m assuming (principle of charity here) that you do have some.

Decisions are really easy to make when you have no responsibility - whereas having one of your patients die from brain bleeds on anticoagulation (as well as having patients stroke out when anticoagulation might have prevented it) tends to give you a healthy appreciation for the harms on both sides of a decision that you make about people’s lives
> As it is, any approximation of absolute mutual information is predicated on the existence of said information.

That's not true. I can approximate a circle on a piece of paper or with a computer or whatever without there ever actually being a true, platonically ideal circle in the entire universe. Similarly, I can construct a heuristic which approximates shared information without that shared information existing in the first place.

Chromium Ungoogled repo [1] made it to the `top30` some days ago. I too have switched back to Firefox with the release of Quantum and have been very pleased.

Frankly, I am amazed every day that Ungoogled Chromium, Firefox, & DDG.co are as good as they are. (aka: slightly inferior to Google regarding product polish, but truly "good enough" 98% of the time - without selling my future data down the drain)

What? That "context" seems absurd considering that the alternative is that the person has 0 warning and 0 indication of either kind of a-fib. Even if the person doesn't have paroxysmal a-fib but the Apple Watch detects an irregularity, I think it would be grossly irresponsible for a doctor to prescribe anticoags without confirming some kind of condition.
Apple Watch 'gameifies' fitness. You set a goal of burning a certain amount of calories, "moving" a certain distance, etc. -- and it tracks these things, and gives you little "awards" for when you successfully meet your goals per week or per month, and tries to encourage you in smart ways if you're not making your goals ("Hey if you do a brisk walk in the next few minutes, you'll have met your goal!!"). I find that these reminders work pretty well for me.

As well, if you have peers who have Apple Watch/fitbit, there are tons of apps you can use to "compete" with them.
I was thinking of various replies to this, but then I realized I don’t really want to have a conversation with someone who starts their comment with “Are you kidding?” Suffice to say that if you wanted to build a rocket to launch satellites as cheaply as possible, the result wouldn’t be an A380-sized spaceship with enough living space for a hundred people.
Wait, so the argument against having more data is that sometimes that data is misinterpreted or misunderstood? That does not seem like a good argument.

You mean apart from the obvious?
Sure, I don't disagree that many "blockchains" have no need to be such.

There is, in my mind, justification for there existing at least one distributed computation substrate where machine-agents can basically play a https://en.wikipedia.org/wiki/Nomic together, each asserting rules into the system, and then moving data (including data representing physical assets, and new rules) around according to the thusfar-established ruleset. Basically, an extensible distributed stock market where different negotiable synthesized instruments, each with their own rules, can be brought into being and traded, without needing to get buy-in from anybody, by just throwing them on there and seeing if anybody is interested.

(You know, the thing that there was enough pent-up demand for that the very first even-somewhat-viable distributed computation substrate, Ethereum, was forced into this shape despite not being very well-suited for the job, having been designed for entirely different kinds of computation.)

That's pretty much the only good case for a smart-contract blockchain as such that I know of, though.
