Hmm. I thought about this for a minute, it's a good question.

First of all I realized that audio processing is at a really awesome point right now: you could train a system to capture your dog's voiceprint when it barks! I suspect that would be sufficiently unique to only match your own dog in your neighborhood. But this could be attacked by recording the barks and playing them back, means your dog is making noise every time it wants to be let in, and also depends on the dog learning new tricks ;)

Then I wondered about GPS tracking, then realized that would be stupid since this doesn't require absolute positioning.

So then I thought about Bluetooth LE. I think this is reasonably short-range(?).

Then I thought about those tiny 2.4GHz 2Mbps radio modules you can get on eBay, and fiddling with one of those to set the output power weak enough so it only works when really close. But that might be so close to "not transmitting at all" it might be very flaky.

But the above 3 ideas all require battery replacement in a collar.

Image recognition does sound like the way to go. One thought that does come to mind though - capturing a wide view of the environment and requiring both "dog within small perimeter around dog door" AND "empty environment with no additional objects in it", for additional security (especially if the dog door is positioned such that it's not too hard to reach up through the hole to the doorhandle). Some tweaking would probably be needed to make the system resilient to birds and objects moved around the environment.

Very nice, a history of when bookmarks were added would be a great addition.
I personally find bodyweight fitness (aka calisthenics) incredibly challenging and satisfying. Good routines are based on progression from easier forms to more difficult forms, emphasis on form over quantity, and at the end of the day, you'll learn some very impressive skills that require tremendous, functional strength. Equipment is minimal - a bar to hang from, a floor to resist you. There is enough complexity, challenge, and progression to last a lifetime. I gave up climbing for it. Reddit's bodyweightfitness subreddit is excellent. Head there for more info. The community's recommended routine is a perfect place to begin.
It took me about 3 months (two different times a bit over a year apart). Each instance only lasted for about 4 months when I'd just lose motivation. Maybe it was because I made an accomplishment each time (being able to jog half an hour without stopping for the first time in my life was the last one), and that feeling of satisfaction meant I no longer had a drive to accomplish something anymore.

I still have my goal of being able to run indefinitely, but I'm just not motivated to start back up again.
Is there a mapping system close to being as reliable as Google Maps?
> Sometimes science involves learning things for which an immediate economic benefit is not apparent.

Exactly. That's why I want to find out how you would react to being stimulated with a powerful current 5 minutes after you fell asleep. My thesis is that you wouldn't last long, but who knows what use could come from the experiment decades down the road? So instead of delaying, strap on those electrodes so we can make some progress up in this bitch. As you yourself said, knowing more things is almost always better than knowing fewer things.
Obviously the advertising engine is divining your true wants and desires.

More seriously, if a person was known to be a privacy nut, I would serve them randomized yet diametrically opposed "advertisements" (say barbie dolls). Periodically when their guard was down I would throw in an ad for a firewall or rfid blocking wallet.
Completely agree. My 4 year old had zero (pun intended) issue playing this up to level 5 just now (using keyboard and mouse on my PC) and absolutely loved the entire thing.
Right. Only their special 300lb pods.

It takes off vertically on electric props and transitions to horizontal winged flight driven by a fuel-powered prop. That's how they get reasonable range. Several other big drones use that approach, and it seems to work.

We may see full-sized aircraft which work like that. NASA has been fooling around with electric VTOL takeoff and transition to winged horizontal flight.
Most aircraft which do that transition are mechanical nightmares, like the Osprey. It's starting to look like having a separate VTOL electrical propulsion system can compete with mechanical transition VTOL. It's certainly simpler.
Yes; relevant context is the flagged-to-death parent post.
Couldn't agree more. I'd tip for this or buy it. My girl just spent a solid half hour playing it and got really into it.
I believe the reason for this is simple (though understandably unpopular):

A lot of people that get rich because of America would just drop American citizenship once they do get rich to avoid paying back into the system that allowed them to become successful.

There is no other country that offers as much upward mobility as the US to its citizens. Hence the tax.
Idk, back then I had worse luck with Macs crashing on me than Windows.
Me too! I would love to hear more about your experience.
Seconding this. My daughter spent half hour playing this and absolutely loved it. Got up to level 5 and was doing OK but that's where she started to make a few mistakes. I agree with all your points.
This doesn't really work for a lot of people because now on top of still being inconvenient and not changing the willpower aspect, there's also the constant knowledge that you're spending money on something you don't really need. The only exception I can think of is if the gym could literally go to you, as in good fitness equipment in a large van or small truck that drives to your house with the trainer.

I find this a weird take because we're in a renaissance of quality story telling TV right now. Keeping in mind Sturgeon's Law, only 66% of tv being crap is a win.

Too bad, there is no abstract in the paper.
Some people cannot find motivation to exercise alone. Did you enjoy rock climbing itself or the community aspect of it and socializing with people. May be you need a partner for your workouts to keep yourself motivated. I tried Peloton bike in the gym a few times. I am not a fan in general of stationary bikes and treadmills, but Peloton workouts are fun, and you a part of an online community. The bike is expensive though, but if it works for you it may be a great long term investment.
Does it raise your BMR that much? What is that energy doing exactly? Does your body temperature increase? Do you move around more? You can't have energy going nowhere, of course. What other activities can drive the same? And what is the magnitude?

"The extra muscle mass you built also raises your BMR in a longer lasting way."

Unless you are talking about fantastic amounts of muscle mass here -- 10 pounds of muscle will only burn an extra 60-70 calories a day -- this oft mentioned factoid is unnoticeable in daily calorie expenditure.
Exercise is the best! Physical and mental gains, guards your health, keeps you young.

I had a gym close to my office, and used to take the lunch hour to exercise. Really made the day go quickly! (Sadly, that gym moved and now I have to work out after work. But the upside is that I now go with my wife, son and daughter.)
You don't think there might be any merit to the idea that women/led charities have more difficulty getting large donations?
A generation was raised on usable designs which clearly communicated interactability with a consistent visual language. It is only natural that they would come to think of computers as inherently ordered, understandable devices. Machines had always been this way.

It was obvious to this new generation that the affordances of youth were purely redundant. Clutter. Overhead. Junk! Widget by widget, pixel by pixel, bevels were smoothed. Tasteful gradients and transparency replaced harsh outlines. Explanatory text was tucked away. Manuals became brochures, then a lonely slip of paper with a URL. Maybe a QR code.

Now my screen is the very picture of elegance and sophistication. There are no extraneous details. Indeed, there are no details. I caress my phone's surface gently, hoping to see a sliver of its rapturous visage peel back, hinting that I have found the first step in the puzzle box of its interaction model.

Alas, no dice. Maybe I can hunt down a how-to video... to show me how to hunt down a video...
I've had the same experience with exercise as you, but instead of rock climbing I really started to enjoy group yoga for a while. I used to attend a free class given by a friend and his wife in their home. The only reason I stopped was because it was a half hour drive each way on Monday, Wednesday and sometimes Friday night. It ran from 7:30pm to 9pm.

The people there were very serious about practicing yoga and I was completely out of my element. What I liked about it was that it was very challenging, fulfilling and I saw a great results within a month. My energy levels were way up, I felt balanced in more areas of my life and I was losing weight. Being part of a group really motivated me to do my best and to go the entire 1.5 hours without quitting. I also enjoyed the bit of socialization before and after class. The hour of driving started annoying me after a few months though and work got in the way at times, so I eventually stopped going.

Recently, I've been thinking I'm going to turn my 2-car garage into a gym to hold my own regular practice. I love the idea that people would come to me instead of me going to them. I'm still thinking about ways to attract the right kind of people to join in. I am no Yoga Guru. Perhaps I will see if I can find some newly certified yoga teachers and ask if they want a place to practice with a group. If I can't find a real teacher, I think I might just fake it. Sometimes if you can't find the Guru, you just have to be the Guru...
If I was offered a free ride on an Osprey, I'd laugh, then run away as fast as I could.
You can probably get a rock climbing / bouldering setup built at home depending on how plenty your plenty of money is.

Then anything you do cardio and weight lifting wise could be in support of your climbing goals depending on where your weaknesses are once you reach a certain level.

I enjoy weightlifting because it makes me eat better, sleep better and thus feel better and I like how precisely you can measure progress (compared to team sports for example). A squat rack, bench and Olympic barbell at home is all you need for a simple program like StrongLifts 5x5 which takes very little time.

At the end of the day, you can be Jeff Bezos rich but Jeff still has to do the actual work, perhaps with a little steroid help though he seems jacked. Fitness is one of the things you can't just buy outright.
> 18 people have died in space exploration since the 1950's. Over a million people die in car wrecks each year on earth

I was curious about the statistical risk here, so I crunched some numbers.

There are approximately 230 million licensed drivers in the United States alone¹, versus approximately 560 astronauts². So let's do the math here:

18 space deaths / 560 astronauts¹ = 3.214%

1,850,000 US automotive deaths² / 230,000,000 US licensed drivers³ = 0.804%

50,000,000 worldwide automotive deaths⁴ / 1,200,000,000 worldwide drivers⁵ = 4.167%

So by US automotive safety standards, space travel has a long ways to go in terms of fatality reduction, whereas by global safety standards space travel is approximately on par.

¹: https://en.wikipedia.org/wiki/List_of_astronauts_by_name

²: https://www.asirt.org/safe-travel/road-safety-facts/ (your link), assuming the 37,000 per year is constant

³: https://hedgescompany.com/blog/2018/10/number-of-licensed-dr...

⁴: Assuming - again - a constant 1 million deaths per year over 50 years

⁵: https://www.quora.com/What-percent-of-the-world-population-k..., which assumes that there is at least one person capable of driving per registered vehicle in the world; this is almost certainly a drastic underestimation, since it doesn't factor in passengers at all.
The same is true for China and its 99 year apartment leases. Everyone is assuming the government will roll over the leases for minimal fees, or eventually repulsed the leases with a proper property tax, but nothing is guaranteed yet.
I think the issue is that the version number and name change would be the same line. Maybe you'd see that the line changed and that the version number changed and assume that was the only change for the line. (Depending on client, might not highlight specific sub-line changes)

Huh. In Canada you can’t buy land on First Nation reserves. They do 99 year leases, but you buy and sell the home the same way as if you were buying the land as well, since the expectation is that the lease would be renewable for the foreseeable future.
The Peloton wife would like a word with you...

But in all seriousness, it sounds like a Peloton bike might be a good fit for you. You don’t need to leave the house and the live classes should alleviate some boredom. It can probably even help with your desire to throw money at something. I’ve not used them myself, but have seen a neighbor who has one in her garage. She got into good shape impressively quickly after having her second child.

They probably can, but they won't until they have to.
I found BJJ (Brazilian Jujitsu, aka "pajama wrestling") to be the thing I enjoyed and could integrate into my life. This isn't going to be for everybody - hardly anyone (statistically speaking) steps onto the mat to begin with and the drop-out rate is savage. However, it's been the thing that keeps me fitter and saner than I would be otherwise - and it's a brutal reality check when you start getting fat and/or lazy.

I don't think the specific thing I do is likely to work for you - or most people - but I think having a real sport to work on that's a sane distance from your house (my gym is a 12 minute drive) is a good chance. Ideally take a look at the profile of the sport and see if (a) you like the idea and (b) there are actually people your age and fitness level doing it in any substantial numbers (i.e. at 47, I'm not going to take up gymnastics). My wife likes tennis, which is about a 5 minute walk away and there are plenty of middle-aged weekend warriors doing that too.

TBH if everything out of the house is that inconvenient you should be rethinking where you live, but that's just my prejudice - one of the major factors in selecting city/neighborhood was proximity to a wide variety of activities in easy walk/drive distance. Obviously you may have a lot of other factors keeping you where you are that are more important.

Totally agree. I did this after a few years off being a competitive track athlete, and trying different sports. I got a personal trainer to come to my house 3 times a week at 6am. It works because you don't have to think about what to do, you're just told to do it. You can't get out of it because they're coming knocking on your door at 6am, and you end up having some fun and interesting conversations. That got me back in to track athletics with a coach and it's something I look forward to every day.
Curious, would you ever approve a third party change to a lockfile? I maintain a very large OSS project and I don’t know any reason I would accept a PR that changes the lockfile.
With NPM, this is not true. You can reference exact versions in every single entry in the package.json file and it doesn’t matter.

Each one of those exact versioned libraries you referenced will itself likely have semantic version dependencies which may update themselves. Unless every single dependency you depend on also follows the policy of pinning to exact versions (and their dependencies do the same, and so on), you are still vulnerable (See left-pad incident, which was a sub-dependency of babel).

The only way to avoid this is the old shrinkwrap or the new package-lock.json feature.
Some fasting would probably help this guy a lot.

Another under-appreciated point: in the end, aging & chronic disease are due to metabolic activity, and reducing your metabolism x time AUC probably has a lot of benefits.
Consider adding your own needs to “management.”

Your mind and body need rest, you have a need for social interactions with friends and family, a need for at least 8h of sleep (see why we sleep) etc.

Your body is your ultimate manager because when at some point it says no, you’re out of luck and choices. Respect that.
> Now I'm far from retirement age

that's why you feel this way. After you lived a life and developed social ties and relationships in place it would be impossible to rebuild those in a radically different country.

Statements like "Retire to Vietnam!" are mostly absurd nonsense - really to go to a place you can't even read the signs?. The most valuable asset one has are the social ties - far easier to live in a boring German village where you know most people than in the most dynamic place on Earth where you never lived before.
In CA, they call it mosaic. But this mosaic has lead to significant anti immigrant sentiments lately. See Québec's Law 21 and to some extend Law 9.
I understand that $2 / month is not trivial for everyone, but this criticism alone is simply not helpful. If a person, such as yourself, does not value the benefits the service provides as greater than the price, they are simply not his/her target market.

Your argument could be that the price asked would limit his/her market needlessly by simply being too high, but at this price point I doubt that to be the case.

He / she built a service with a clear value prop (fastest food logging possible, backed by high quality / custom data, with a privacy focus). For those interested in food logging without having their eating and nutrition habits / data sold off, I doubt the price would be a deterrent.

Maybe you can say the service is not meeting expectations in some way. That’s fair, but then please provide more specific feedback.

Given the nature of this forum, let’s try to be either more supportive or at least more clear about what could be improved. Drive-by negativity is just not helpful to anyone.

I, for one, applaud his/her efforts, find the offering enticing and the price to be very reasonable (Probably too low, in reality) given the attention to detail, data provided, and problem being solved.

Disclaimer: I have not used the service and have no association, only browsed the site. I rarely comment, but wanted to balance out this low-effort negativity.
I was under the impression that the biggest driver of marketing costs for drugs was providing free samples of the drug to doctors, with training doctors coming second and advertisements a distant third.
I have a huge problem with someone who says, "We should just make compensation merit-based rather than based on accidents of birth", because it refuses to acknowledge that we already live in that system. It's just that the "merit" is stuff that happens to correlate strongly to accidents of birth (like IQ, speaking the "correct" dialect, being well-educated, and so forth).

It turns into, "our system is broken, we need to system _harder_", and is just as much nonsense.

Ask HN: What technical problems must be solved for blockchain to be fundamental?
The title is lacking due to length restrictions (any suggestions for better phrasing are welcomed).

Bitcoin is more than a decade old. Technological growth can be exponential, which makes me question if there will be an explosion soon due to technological breakthroughs in the blockchain space/industry (or did/am I miss/missing it?). I'm curious from a technical (and perhaps economic perspective) rather than political in an effort to focus upon the engineering effort that is required and could be possible without economic or political intervention. [i.e. improvements in transactions per second, improvements in energy consumption, improvements in ...]

1. What technical problems must be overcome in order for blockchain technology to a fundamental platform for society?

2. What are the potential solutions to these technical problems?

3. And how close are those solutions to being attained?
