Photon to electron to chemistry to electron definitely has a huge efficiency advantage over photon to electron to photon to electron. The battery has about >90% round-trip efficiency while the wireless power transmission over thousands of miles has on the order of 33% round-trip efficiency once you add everything up. That means that in order to get the same energy, you need almost as big of a solar array as you would in a good desert location even though you get 24/7 sunlight!

And it's not even the conversion efficiency that's the problem. It's the cost of the conversion equipment. The power electronics, the microwave amplifier, the array, the receiver array, rectifiers, and power electronics as well as transmission all has a MUCH higher cost than the actual solar cells. Additionally, the minimum size space based solar power satellite and receiver station is super expensive, and the situation only starts looking like it might be worth it when you approach multiple Gigawatts per installation.

In some ways, space based solar power is based on the idea that solar cells are expensive and scarce and their output should be maximized. Nowadays, that's a strange thing to believe because solar cells go for 16 cents per Watt on the spot market, so we tend to emphasize the constancy. But really, even that is falling prey to technological advances in battery technology.

As far as "ground stations are a small portion of the total cost" and "point power to the places you need it most," that's simply not true. The ground stations would rival an equivalent solar array in cost, not even counting the space-based portion at all! But I suppose the in-space portion WILL be crazily expensive, so you might still have the ground-stations a "small portion of the total cost" while still being crazy expensive.

And due to the diffraction limit and required safety margins, your ground stations will have to be huge. You're not just going to beam power into the middle of cities with high aircraft traffic and safety concerns. The exception to this would be if you used much shorter wavelengths, such as mm waves or lasers, but there the cost of everything (amplifiers, optics, etc) is much greater, the realistic round-trip efficiency drops to like 10-20%, and you become much more susceptible to weather. Oh, and what you're building now looks a HECK of a lot like a weapon.

Kubernetes is a thing that makes it easier for one program to talk to several other programs, by tying them together with elastic string, and putting them in whatever room it thinks they should live, and makes them as big or small as they said they needed to be. It runs in the engine bay of the truck, not in the cab of the truck, or in the container.
Seems someone else was able to get it that working: https://blog.jessfraz.com/post/building-container-images-sec...

Why are people so indifferent and why are they just standing by and not asking relevant questions and not demanding for proper test/procedures in place before continuing the test of SDVs?
In a lot of cases, from my understanding, disabling storing data about "your account" just stores data about you with an anonymous identifier.

For example, voice search history you can enable or disable, if you enable it, you can see and listen to all your queries and delete them if you so choose. If you disable the history, Google still stores recordings of your voice and uses it to "improve their service", they just associate it with an anonymous identifier. The downside here, of course, is that you can't delete the copies of your voice Google is now saving despite your desire for them not to keep your history.

(I am having a hard time finding exactly where Google currently states this, but I have a high level of confidence this is how it works, as officially stated by Google, for voice activity.)
"bit" in French means "dick" (though the spelling is slightly different, being "bite"). Then again "god" is a shorthand for "godemichet" which means "dildo" (spelling again being slightly different: "gode").
As said above, I don't think anyone is confused except for you.

Don't get me wrong, I think vegans and vegetarians can sometimes be annoyingly hypocritical and arbitrary, I think I see what you're trying to get at, but as for what constitutes a typical vegetarian diet I don't see why it's so hard to see the difference between milk and meat.
Cap table debt – and how to refactor your shareholder base
How feasible is it for Google/Facebook to infer/build profile of private browser activity?

Since most sites implement google Analytics and Facebook tracking code (ghostery is reporting both on the guardian website). They could use browser fingerprinting, which has already been proven to be extremely accurate, to augment known user profiles and data. Facebook already creates shadow profiles for people without profiles. I don't think there's any US law from making these inferences from "voluntarily" submitted information so it's perfectly plausible they would do this without telling people, no?

A more compelling argument for users to take privacy seriously would be to tell them: Hey guess what Google has the ability to know what porn you search for (yea even in your private window) since you're sending them all the data required to track you, and there's no laws in place to prohibit it.

The best way to get started is to follow the official guide https://kubernetes.io/docs/tutorials/stateless-application/h...

You will use a tool called a “minikube” which is “mini” version of kubernetes that runs on your local machine.

You should focus on to get familiar with kubectl(1) first, it’s a simple CLI tool to manage kubernetes cluster.

If you have any questions & issues you can ask on Stack Overflow #kubernetes and you can also join the Slack channel.

If the sender is on gmail, and you delete the message, does it remove it from their sent box as well? What if there are multiple recipients?

If you reported it as "not spam" and then trash it, is it removed from the "ham" training set?

If it is collected as part of a warranted intercept and you delete it, is it removed from the intercept collection as well?

If you delete an email, are any resulting changes to your personal ad profile maintained by Google reverted?

Deleting an email from all of Google is not quite so trivial as "empty your trash, and it's gone entirely".
I just thought of something, all the attention that this is finally getting means you can go dark without raising suspicions.
Awesome! Now worldwide ;)

Ideas:
-Open up to the main local bookers (in my country that would be one firm, Mojo), monetization via referrals?

-other awesomeness would include: local clubs and pubs access via API, same monetization.

-Main few hits per band and then select bands that "sound like" selected view of the most listened to bands.

-Anything that makes me discover worthwhile bands in my area that give me an unexpected nice night out without having to notice the social media multiverse (my favorite teen bands from 20 yrs ago got together last summer and I noticed last week.. guess I haven't got any of my teen surf punk friends anymore)
Fantastic idea.
I was actually surprised going down the list at how little Google has on me. I mean, I've used Duckduckgo for a long time and never used Android, but forgot I had turned off ad personalization and deleted youtube and search history.

I'm surprised they didn't have anything in search or youtube because I deleted the history long enough ago that I didn't remember doing it, so I've successfully stayed away from using them.

Still waiting for the data download, but I know they have all my gmail messages and some stuff I put on Drive a long time ago.
Slightly OT, however; Pros buy snap on because of convenience. Most know there are cheaper, better made tools available for the last 25 years. The tool trucks, and big lines of credit, and bling factor are their only remaining upsells. The 'made in usa' stamps are even disappearing from their tools as more come from tiawan and china. It is hard, if not impossible, to justify the markup without some huge ego stroking, tradition and deliberate lack of comparison shopping.
> Bear in mind, these companies know which ads they've shown you and when, for example, and at least in one case, buys your credit card transaction history to compare your purchases with the ads you've seen.

Correct me if I am wrong but are you saying one of these two companies buys people's credit card transaction history and then compares people's ad history against the transaction history? If yes, that sounds really incredible.

Devil is in the details. There's just no place to reliably source all of the events that are happening. Sure you can get the ones that sell tickets through ticketmaster, or whatever, but nobody reliably aggregates all the smaller concerts. So this will always be badly incomplete. Discovering all those shows is on of my main use-cases for facebook right now - it's the one place (almost) all of them show up.
Yep. App Transport Security mandates that you have to explicitly whitelist the domains [0] which you want to access via plain http. This however, has nothing to do with certificate pinning, which the OP was mentioning.

[0] Of course you can use the blanket NSAllowsArbitraryLoads to allow plain HTTP everywhere.
To follow this up, can anyone explain the benefits over Docker? I've used Docker before but am unfamiliar with Kubernetes terminology. I do understand it's an open source project by Google.
I dislike advertising and I'd love to see marketing move from a "push" to a "pull" model, where consumers ask for information about products they want. It's not easy to see how we get there. Defending the right of consumers to block ads, and moving from ad-based funding to subscriptions could be a start. An outright ban on ads - I don't see how that could happen without overreaching to non-infringing speech.
Most of these tools have been around for more than 5 years, many organizations have invested tons of money to use them, and each is supported financially by one or more corporations, so by that metric alone they aren't going anywhere anytime soon.

Resignation obviously can mean resigned to, eg

"having accepted something unpleasant that one cannot do anything about"
"he has a pet bird" "she has a pet squirrel"

There's nothing wrong with "pet X", you're just used to dogs and cats being pets by default.
True; I was lucky enough to be able to find a path through the maze that goes around most of my mental barriers. There’s no guarantee such a path will exist, and even if it does, it’ll be different for everyone.
AFAIK that is already illegal in the EU, and certainly will be under the GDPR.
Do you have a link to a study that supports your assertion? I find it difficult to believe that plant foods are universally toxic to cats. In fact that sounds like it can't possibly be true or scientifically verified.
Well, even saying no in a particular tone of voice can be accepted as a scolding, especially if the tone is in higher notes. What is a particular tone of voice, which will not effect them in a way that scolding does? They are not human and cannot express their minds, which makes it more complicated to understand whether you crossed the line or not. I remember talking to the kid the other day and saying no to something in a very calm but firm way, she said I was scolding her and didn't understand why I would do that. I hope it does complement my point.

I didn't disagree with the fact that it is the ideal way of raising them, but sometimes being strict wouldn't hurt if the other methods don't work. And by being strict I don't mean being violent and beating them, since I am not a violent person by nature.

> If the sender is on gmail, and you delete the message, does it remove it from their sent box as well? What if there are multiple recipients?

Obviously google won't "unsend" email, they aren't a DRM platform that will delete data anywhere that anyone you have ever shared it will has ever sent it.

> If you reported it as "not spam" and then trash it, is it removed from the "ham" training set?

But things like "spam" email will be "unlinked" from your account at the very least, and possibly fully deleted (does information "learned" from a spam email count as that email in your mind? If they use a neural-net to train spam filtering does that become "your data" when it learns from something of yours?)

But regardless, I didn't want to get into internet arguments about what the big companies might possibly be doing through a shitload of what-if's. I just wanted to point out that the reason the author of the blog had 'deleted' things in their takeout was because they were in the trash, and the trash wasn't emptied...
>The critical point which is being made is that the Pr0gramm users donating to cancer research and the Pr0gramm users mining through Coinhive might be different people, and lumping them together because they all use Pr0gramm would be unfair (this is the argument they're making--I don't know whether it's true).

I think you misunderstood something. Pr0gramm users can use something like coinhive voluntarily, on their own machine only, unless they like blasting their login data out into the internet. This can be used to get premium time for this pr0gramm account and nothing else.

The connection here is, that this was the prototype for what is now coinhive, which has been developed by the former pr0gramm admin.

This is the connection between pr0gramm and coinhive. I don't think anyone ever claimed (not even Krebs) a lot of pr0gramm users would be involved in blackhat usage of coinhive. It's an imageboard with thousands of users. I mean, seriously, the amout of people on HN proportionally that use coinhive in a blackhat way is probably higher than on pr0gramm. Simply because most people here have the technical skill to do it, where pr0gramm is simply a website for shitposting.
Accidents like this will spur the AV community of companies to form a body (AVI?) to protect AVs from bad press by enacting a set of rules for all AVs to abide by.

Eventually, gov't policy will take AVI rules and recommendations and formalize them into their own books. But until then, the whole thing is deeply experimental. And regulation is premature. Otherwise, you may be crushing potentially great ideas unknowingly.
...and once again, an article that could have actually gone in depth on this topic, manages to leave out the data these companies collect and purchase from third parties (e.g. credit card transactions) and public records.

It's funny, I bet Google is glad this article is out there. Look how easy they make it to see "everything" they know about "you". And you can delete it if you want!

When they are thinking about this article, no one will worry that you can't see any profile they have for you when you aren't logged in.
It's a link aggregator and a webforum. As far as I'm aware, you don't friend people or submit original content, or follow that of others. I would not consider it social media.
I admire your optimism, but I just can't share it.

That licensing rant ends with the line "And it will only cost $30 per seat." (for and education-specific version) while also specifying a plan that would prohibit distribution either by or to education institutions.

I really don't have a problem with commercial software. But schemes like this, trying to get the best of both worlds and in the process undermining the meaning of Free Software always strike me as both destructive and pathetic.

It's not even that hard to properly execute a dual-licensing scheme: they could license the code under GPL, which would make it hard to impossible for others to commercialise. Then, they could offer a commercial license to educational institutions, and would be the only ones allowed to charge for such a version.

But the tone of that blog post makes me think there's more that's wrong with this project than just their licensing.

I get you. It's really variable what someone's person AL definition of vegetarian is, which often defies what the intuitive definition is. E.g. meeting a self proclaimed vegetarian that eats fish. Yes, we'd call that a pescatarian (or just an omnivore) but they stick to "vegetarian". I think that the inconsistencies come from that vegetarian means some types of animal products, and the types become unclear.

And speaking personally, vegetarianism is morally inconsistent, too. Just leave the whole animal alone!

IMO that's another thing you learn with time. There's no sure path.. you oughta crack through. Which is a bit paradoxical since you actually lack willpower but it's the only way.

It's like todolists.. I have thousands of them. Nothing happens. At times I just roll up my sleeves, in a very thin anger, and just go through chores and duties.

Now that I internalized that notion I'm much more willing to do things rather than procrastinate and day dream about how I would/should/could.

I'm not 100% proactive, far from that, but I know I'll be much happier if I do be (sic).

In a bad organization many people that would perform to satisfactory levels begin to underperform. One signal of this is when individual responsibility is removed from the equation.

I enjoy organizations where individual's expectations are clearly defined, and I prefer if there are consequences for missing those expectations because I feel like it increases the reliability of the team.
I did this as well, and it does work well.

At work, when I ever found myself thinking about checking reddit, facebook, etc, I would instead step aside and do pushups. It improves my productivity.

Until I started getting criticism from others about doing push ups, it had worked well. I realized my depression/anxiety was external.

Even when I moved, one of the bizarre things I encountered were people criticizing me for doing pushups, even though I stopped doing them. It was either one of several freak chance things, or there really was/is negativity coming from external sources in my life.

Well, sorry for a bit of a personal rant, but if you need help, might as well put yourself out there a bit, I suppose.
This isn't a full explanation, but Kubernetes isn't a direct competitor to Docker -- but rather Swarm, Docker's orchestration solution. Both work with Docker (or one of it's direct competitors such as Rkt) to orchestrate multiple containers that work in conjunction with eachother.
