>as if losing money overall on your house means it was a poor choice.

From a financial standpoint, that does make it a poor choice. Losing money == bad investment.

I've been listening to some other commentors on the subject and that has evolved my position a bit. Smart people change their mind when new info/viewpoints become available.

>average rent in your area vs house prices, cost of living in your area vs other areas, our salary and where your job is located

Rent is pretty much always a function of home price so, again unless there is a qualitative reason (like you have a big family and you need 3-4 bedrooms) renting is going to make more financial sense. You statement on cost of living is wrong. Places where the cost of living is high will have high rents and home prices.

My OC was not about comparing the monthly costs of rent vs. buying. It was pretty explicitly about a home not being a good investment when the actual cost (including total interest and incidentals) is factored in.

The bottom line is, there are cases where it will make sense to buy. For most people, this is not the case and they buy simply because they are ignoring the actual cost.

Oh yeah my post was half joking, half playing devil's advocate to the oversimplification of the tweet it was replying to. But either way, the point was that getting (only) non-criminals off encryption still makes spotting criminals easier, which I don't think is an oversimplification.

Is efficiency a game-stopper? I would assume the low wifi power levels are the main problem, but that can be solved by cranking up the power. And you can aim the source.

This is a very North American ideology, lots of families live in very small apartments around the world.
"Apparent" and "noticeable" are terms that point to characteristics that we, as humans, are able to notice. A 1% more chance of survival is hardly noticeable by a human being without the tools of controlled observation and statistics, however the mutation that allows it can spread very quickly through a population in a few generations.
Optimization is a matter of fine tuning, so the effect of mutations has to be small enough to allow it. Sometimes a slightly larger mutation can create such an advantage that a cascade a smaller mutations ensues to fully exploit its potential. However I'd say it's more he exception than the norm.
Just like I always say, all a man needs to succeed in life is maths and squats.

I agree, it's ridiulouly low. From the article:

> In their proof-of-concept experiments, the team demonstrated that the PoWiFi system could wirelessly power a grayscale, low-power Omnivision VGA camera from 17 feet away, allowing it to store enough energy to capture an image every 35 minutes.

I made a back of the envelope calculations for a similar project ( see https://news.ycombinator.com/item?id=10323565 ) This other projet claim that they can harvest ~30µW, this is very little. For example, it can only blink a led a few times per minute, because a normal led use 30mW=30000µW. Read the complete comments for more details.
I recently saw a talk on this, and I didn't understand the barcode charts then either. For example, I understand that the zeroth order Betti number gives the number of connected components. So, why does the bar code chart show multiple numbers for each radius value? Shouldn't it look more like plot of some non-increasing function where for each radius, there is a single zeroth order Betti number on the y-axis (since the number of connected components is non-increasing as a function of the radius)?
Diamond mining is highly mechanized. There definitely are local workers but fortunately it is no longer as labor intensive as it used to be (that's bad because fewer jobs, but it is also good because those jobs were super dangerous and very low pay anyway).

Paper (linked in article) is here: https://homes.cs.washington.edu/~gshyam/Papers/powifi.pdf

Disregarding the usual HN snark for media terms ("game-changing") and the usual criticism ("been done before", "won't be effective"), this is actually really cool. If we look at all the innovations in the past year, this is a pretty dang neat one.

They mention Tesla in the opening line of their paper. In short, the biggest innovation they came up with was solving the mismatch of Wifi operation and optimal power transmission. Read the paper; it's quite good stuff.
100% agree. That's how I grew up too and I never felt like I needed/wanted more space.
Only if this is cheaper, and you have room for a big antenna.
Wireless transmission has been demonstrated by others before Tesla e.g. Heinrich Hertz. And I mean induction is arguably a form of wireless transmission which has been verified by Faraday in the 1830s. The problem is now as it was then that wireless transmission is governed by the inverse square law and therefore inefficient to the point of being unusable in most real world application.

It's not enough to power a thermostat. µW is microwatts. WiFi radios need milliwatts. As jimrandomh mentioned, the levels of power here are the same as what a watch battery can provide for eight years. Watches don't even run off of a watch battery for eight years.

So if one doesn't care about home renovations, building property value over time, that pride that comes from saying you own (but mortgage == owning something fully in x0 years?) something, and wont mind moving if prices change, then it seems like one should stick to renting?
First tech needs to focus on small distance wireless power. I need to be able to easily and reliably charge my phone wirelessly. Plugging in wires is just straight up old fashioned. Qi is really getting mainstream now but having to position the phone perfectly is not that great. I know of A4WP with NXP as one of the main companies developing tech that can charge everything over the pad, no matter the placement. It also includes stacking. If we can build out this to also be integrated in laptops, lamps and other "put down" devices, I can believe this can evolve into something larger doing it over a bigger distance.

There's the whole "I am not poor but I have compassion for those who are and don't want them to die and suffer for lack of medical care" angle that you might want to consider.
It is interesting and could be a game changer for the 'internet-of-things'. WiFi is everywhere and just to be able to run a device a couple of seconds per day without having wires attached to it could enable a huge number of applications.

Get your raise going out the door, relying on the ones your company gives you is the route to mediocre raises.
In Japan, there is a similar idea called "Shared Houses". This kind of reaction to the status quo means that we're solving the housing problem in the wrong way. Instead of providing faster transportation mechanisms, we're investing into places that are even more cramped.

As many have pointed out, a micro-house is unlikely to be good when you have a family and children to raise.
You're not wrong, but you don't quite understand how 20% time works in practice. It's a formal way to recruit part-time help on unrelated projects, and it's recruited for and tracked in exactly the same way using the same systems as normal jobs & normal performance management. It's a fantastic way for people at Google to seek out learning opportunities or places to participate outside their normal team/group/dept/BU.

Most companies look at 20% time as a super-informal way for people to volunteer "spare time" to work on non-core stuff, but that isn't how it works at Google, at all.

That said, your central point is 100% accurate ... but at least within tech, I think that "40 hour, strictly scheduled workweek" has been gone for several years now.

Personally I find internet consuming because I get this feeling of being social, but I never get my need of socializing satisfied. I can "talk" here sure. But going for a walk with a friend and not talking much feels better afterwards.

But this neither might not matter for the majority of internet browsing people. About 50% of population are extroverst like me.[1] The remainder is introvers. It's likely that majority of internet users are introverts, who have lot smaller need for socializing in the first place.

This would only be a problem if you currently spend every waking hour working effectively. It is now 7:18am my time, and I already worked out for an hour, mostly lifting weights. I didn't cut into my work time at all and I'll be way more capable of working than if I just woke up and started work.

As a reasonably experienced manager, I think holocracy can sort of work in the context of largely repeatable units of work, and areas that don't require a lot of focused independent thinking by single individuals. But if you're working on a biz dev strategy, for example, that's just not something a random employee can successfully do and by definition that means it has a dependency on the person/people who can. There are loads of functions at all medium++ sized companies like that.

The barcode is not usually showing the zeroth Betti numbers. It's usually showing the first Betti number, which intuitively counts the 1-dimensional holes in the space. For each radius, there could be lots of those (imagine several circles that all have a single point in common, then the first Betti number will be equal to the number of circles). At a given radius, there will be one bar over it for each 1-dimensional hole. If a bar is really long, i.e. the same hole exists for many radii, then we assume that it must represent actual structure in the data, rather than just noise.

You could do a barcode for the holes of any fixed dimension, but as you point out, the 0-th dimension case is relatively uninteresting, and as you get to higher dimensions, it's harder to visualize and interpret what is going on. So dimension 1 is most common.

It's pretty interesting to me that while we simultaneously demand that companies build everything with power efficiency in mind and embrace environmental consciousness, we take all this power and use it in increasingly inefficient ways.

DO isn't going after large businesses. A startup could get traction on DO and then migrate to something like AWS when they need more flexibility but will have larger costs.

If DO started to offer things like load balancers, managed DBs as a service (similar to DynamoDB and RDS), and Storage (S3). That could change their business quickly. Somewhere between Heroku on AWS is the sweet spot IMO. Heroku is $$$ and very little to no flexibility and AWS almost has too many services now with no focus.
