Advertising is only valuable when the user is engaged with the device. It's a very poor model for mining. Why not:

1. Sell compute when people aren't using their machines and split the spoils (not actually profitable for people who pay their own electric bills, but you don't have to say that)

2. Just create malware miners that run all the time.

You don’t need to download the whole block chain in order to do mining. You just need to know a reasonable starting point.
The food industry should be fined for paying off people to produce so called health studies and fake science. I read some of the comments on that article claiming footballers have great abs because they exercise, this isn't about if you're body is toned, its about your body fat percentage, you can run all you like, but you're never gona run off high sugar foods easily, unless you're doing a marathon every few days. Food is the main way to reduce your weight, it doesn't mean you eat and go hungry, it means you get clean carbs and fill yourself on good stuff. Exercise just helps tone your body up and lost a little more bonus weight.
You only need currently open transactions, a hash from the last block and a nonce.
Remember that rich westerners have a far higher per-capita footprint than the rest of the planet, eg the top 10% has about 50% of the total carbon footprint for example...

This is news that's breaking to a revitalized moon rocket industry with all agencies and players building their own big moon rocket. New Glenn for blue origins, bfr for spacex, sls for NASA, ACES for ULA (boeing aerospace + lockmart
) Chinese have also expressed interest in a moon base.

>the current car tab is at least an order of magnitude too small.

Your opinion may be clouding your judgment. It's not right to inflate the value because you can't pass a higher rate with legislation. This is why a lot of people don't support transit, because the people advocating it can't be honest.

This is also why Washington State voters keep passing a cap on the car tab fee. Like it or not, the voters of the state still get to decide on the rules that govern them. They agreed to a rate increase on the fair-market value of their vehicle, not for Sound Transit to charge whatever they want because they lost some grant money.
Indeed: if a few hundred million westerners made a real effort to curtail frivolous footprint then that 10b may happen with a lower-than-current total footprint.

It's a weird binary thing for me. And not fully under my control. It's like one of those perceptual illusions - sometimes I can stare at them with pleasant fascination, other times it's more a reflex "kill it with fire!"

You are coupled to mvc, that's the upside to a framework.
While the numbers have interesting etymological roots, in practice we just have more "named" numbers than most similar languages. English has special vocabulary with obvious roots for all tens up to 100 and ordinals are regular except first, second and third.

In Danish we just have a lot more irregular ordinals. Practically no-one in Denmark knows about the 20-based number system.

> A Scandinavist language reform movement tried to get the 20-based forms replaced by 10-based like Norwegian and Swedish have. With absolutely no success.

Danes are unusually stubborn that way.

AFAIK JS doesn't really have modules, just ad-hoc use of functions and objects for namespacing
Mining is typically something like:

Hash(nonce + Hash(chain[including with new transactions])) < value.

So in some sense you need the chain but you can pass Hash(chain) to a client and let that just increase nonce and hash it.

Without synchronisation the found block might be for a stale chain but if you're using someone else's power you don't care, and the nature of distribution here means it's likely to be fresh anyway in the unlikely chance something is found.
Speeding Up a Fat Web Client
Mining is just running a dumb hash algorithm over and over. The website would provide the package of data to hash, the browser would start hashing, which could even be done offline. If the browser solves the block, the client sends the solution back to the server. The orchestration and blockchain access is handled behind the scenes by the server.
And they also claim string_views can be constructed from a std::string. That's true of their implementation and it's true of the TS string_view but it was removed from the c++17 string_view.
I think it would mostly be about fending off senseless boredom.

"Detection of intact lava tubes at Marius Hills on the Moon by SELENE (Kaguya) Lunar Radar Sounder"

Intact lunar lava tubes offer a pristine environment to conduct scientific examination of the Moon's composition and potentially serve as secure shelters for humans and instruments. We investigated the SELENE Lunar Radar Sounder (LRS) data at locations close to the Marius Hills Hole (MHH), a skylight potentially leading to an intact lava tube, and found a distinctive echo pattern exhibiting a precipitous decrease in echo power, subsequently followed by a large second echo peak that may be evidence for the existence of a lava tube. The search area was further expanded to 13.00–15.005°N, 301.85–304.01°E around the MHH and similar LRS echo patterns were observed at several locations. Most of the locations are in regions of underground mass deficit suggested by GRAIL gravity data analysis. Some of the observed echo patterns are along rille A, where the MHH was discovered, or on the southwest underground extension of the rille.
This almost occurs to me as funny. Why does it need to be a confession? It didn’t seem like Planetary Scientists have claimed as a group that they “want” to live on Mars. The confession only makes sense if Planetary Scientists are all presumed to want to live on Mars in the first place. And even that is true, it’s not a particularly strong confession as the simple fact of not wanting to live on Mars doesn’t imply a betrayal.
Its a pretty bold accusation. Car insurance is probably the most competitive market out there.

Why would dozens of car insurers in multiple states collude to hurt poor Tesla and put themselves at risk of Federal and State sanction? If they were doing that for a tiny niche automaker like Tesla, why wouldn’t they screw over BMW or Lexus?

This whole controversy is just a distraction to draw attention from Tesla’s service practices and support for a integrated “car as a service” model where Tesla owns financing, sales and insurance.
Author here - Appraise is a new opensource tool for visual test automation. It’s like FitNesse, but for visuals, and working from Markdown that shows up nicely in GitHub repositories.

Appraise can help you:

- Automate acceptance/regression tests for visual look and feel in a visual language, rather than xUnit style code

- Review and approve changes to web pages, visual layouts and browser components quickly through visual inspection

- Publish easily maintainable/verifiable developer docs with visual examples to Github easily (markdown) or as a static site (html)

- Start Spec by Example/BDD from a sketch (hand-drawn, wireframe, or from a graphic tool), easily compare actual outcomes, then just approve the final result to make a regression test

In the near future, Appraise will also help you:

- Speed up visual exploratory testing by making it easier to rebuild visual components from example data/configuration

- Run visual tests quickly/in parallel using AWS Lambda

This is another tool we built for MindMup, and we used it for the last few months internally, to assist with visual checks and test automation. It helped us move away from tedious layout tests that were very difficult to maintain for small changes, but that would be visually easy to approve or reject. Appraise makes visual tests easy to compose and maintain, by letting people describe what they want something to look like (with a drawing, photo, screenshot or a wire-frame), instead of describing how to test it (eg 10 pixels left, this css color). Here it is in action, preventing me from introducing a stupid layout bug: https://gojko.net/assets/appraise-screenshot.png

Under the hood, Appraise uses headless Chrome to take screenshots, so it can inspect anything that Chrome can render.

The initial release of Appraise is alpha-quality. It covers our key usage scenarios, so we think it is ready for some nice community feedback. It’s useful to us, let’s make it useful to you together.

We’ve designed it to be extensible and pluggable, so other ways of executing fixtures, taking screenshots or processing results should be easy to bolt on to it. We’re releasing it under the MIT license, and the code is on GitHub.

It's a new commercially viable rocket engine (not a pork-barrel jobs program) of a size suitable for serious heavy-lift applications, designed and built in America.

Obviously SpaceX is doing similar things, but Merlin, Raptor, and the BE-4 are all part of a pretty exclusive club. I don't know why SpaceX chose to go with a greater number of smaller engines for their planned heavy lifter; I imagine it might be something to do with the difficulty of building bigger engines scaling non-linearly, and the fact that modern analysis and engineering ought to give us some advantages relative to the last time someone tried to make a really big rocket with a lot of little engines (Soviet N1).
Reportedly, dual n-back. I cannot confirm this, however. My focus improved by taking up distance running, but that's not an activity for everyone. To me, it's meditative.

There are many problems

See https://en.wikipedia.org/wiki/Pigovian_tax

For instance estimates of the "social cost of carbon" vary widely

https://19january2017snapshot.epa.gov/climatechange/social-c...

one of the most important factors is the "Discount factor" which is highly subjective. (How much do we care about 10 years from now as opposed to 1000 years from now?)

Some people don't like the idea that "rich people" get the right to pollute.

In some cases "paying money" might just legitimize bad behavior. A day care center in Tel Aviv tried charging people money if they picked their kids up late, it was not successful at letting the staff leave home early because some parents decided it was worth paying the fee.

My ex worked for Christie's and she loved her job. And I heard many hours of gossip. So many hours.

According to her, it's the best place to work, if your not in the shipping department.

Inside information: Suposedly, like so many organizations, it can be cliquey. She told me about this one guy who spotted two fake paintings, but was let go because he just didn't fit in. I was too drunk to question her deeper. One of the painting was over 1 million dollars.
Living on a foreign planet would surely have a _much greater profound impact_ on you, but the profoundness isn't what is important. It's the type of a profound impact that matters.

As an example, let's say you grew up only in the U.S. Visiting a foreign European country might have a profound impact of the type that is very eye-opening due to seeing and interacting with another culture. In contrast, visiting an active war-zone like Syria will surely have a _greater profound impact_ on you, but the type will be one that is very sad.

The same would go for a foreign planet, where the type of a profound impact it would have on you would be one of loneliness, abandoned-ness, etc.
Like others have mentioned, the economics are not good, mining is too competitive to be done on commodity hardware. Consider that over half of browsing now happens on mobile, and it becomes clear that very few people can participate.
I have some nice flash card decks on anki but have failed to make it a habit to look at them. Did you have any ideas on how to make it a habit to do these reviews? For me some of these flash card decks are kind of heavy (e.g. Deriving some equations) and I think my brain just does not always want to get into it.

I’ve been doing c, c++, and objC for over 20 years and am just getting started with Clojure. Sure, it’s easy to understand the basics of clojure in a few weeks but it’s going to take me a while to stop thinking imperstively and objected oriented. Mutating everything is programmed in me at this point. I think it’s going to take me months to get decent at Clojure if not a year. I’m sold in the ideas but it’s not easy if you have been doing imperative style programming . I’d bet it’s almost easier for a novice to pick up Clojure

"I agree. My experience has been that ageist views (just like sexism, racism, homophobia, etc) are more often expressed by people of previous generations and that millennials are actually more flexible and open to the idea that they would work with someone older (or of another gender, different skin colour, etc)."

I think millennials are far more open when it comes to sexism, racism, homophobia, etc by far. However, when it comes to ageism not so much.
I'm only familiar with Bird Law, and as there are no birds on the moon, I am sure that "rock law" will predominate in that if I hit you over the head with a big enough rock, I then obviously own the moon.
It sounds awfully like the arguments that traditionally nationalist groups use against immigrants, contending they're less intelligent and accept lower wages because they're culturally inferior and just don't know better

Is this the new Godwin's Law?
According to link above the treaty prohibits all sovereign claims.

However, getting there can be made into a reasonable barrier to competition. Sure you can also exploit the moon, but how are you going to get there?
I’m probably making a mistake here by commenting before reading the article, but I’ve seen many cases where issues with food prices and food supply have been diagnosed as long term effects of food aid or cheap imported food. What can happen is that local farmers go out of business or stop growing staple crops because prices collapse. When conditions change and the food aid stops or the price of imported food rises, there aren’t enough local farmers left to feed everyone. That will obviously cause food prices to go through the roof. It’s always something that has to be considered when planning aid to a country.
Can you give some examples of applied math sub fields that haven't been exploited to their fullest? I'm genuinely interested.
Proved this for myself and then wrote a book about it.

I personally (Richard Boegli) lost 40 kg in 40 weeks (90lb in 9 months) WITHOUT exercise. [90lb in 9 months (no exercise)].

I chose to do it WITHOUT exercise, as my theory was that I would keep it off longer, if it wasn’t dependent on exercise. Every other time I lost weight in my life, it was a combination of diet and exercise. When the exercised stop, the weight would creep back up, as I was still eating too much.

I wonder if this only applies to the NVMe models (like 950 and 960 Pro)?

Edit: probably not. The 850 Evo spec specifically mentions support for IEEE1668 (Encrypted drive)[1] (probably a typo there, should be IEEE1667).

950 Pro specs say: "EncryptionTCG Opal Family Spec and eDrive(IEEE1667) to be supported by FW update" [2]. Not 100% sure, but I think this update never arrived for some reason.

960 Pro specs don't mention anything [3]

I wonder how stable such tubes would be? No water erosion, no earthquakes, even though they must have formed at a time that was more geologically active.
They could be on the edge of collapse if say, a large vehicle drove in them. Am I wrong?

Just a first thought. Other than that, they could probably serve as a goal for human spaceflight, an intermediate step between walking on the moon and colonizing mars.
This is talking about the “kites” though, not the “gates”.

Thanks for the reply, it was very informative.

I've programmed in dynamic languages for most of my career (about a decade now), and have always missed types. I picked up OCaml (Reason flavoured) recently, and I've been able to enjoy the Hindley-Milner typesystem without worrying about side-effects with complex types, since OCaml is a fine mix of imperative and functional programming.

Language preferences are usually framed as an objective measurement, but I've always found it to be based on our personal experiences. Since you've been doing a lot of Java, I'd surmise that the clean, functional yet dynamic nature of Clojure with Java interop is appealing to you. Me on the other hand has been burnt enough times with dynamic systems that keep shifting from under your foot (Ruby metaprogramming), test suites that makes refactoring more difficult (it provides safety, but the manual labour is unforgiving), and a general sense of dread everytime I put systems into production. But more than anything else, the biggest pain has been the sheer difficulty to refactor growing codebases.

Large dynamic systems, if they manage to not crumble from the inside, usually gets hammered by a sweeping change in external reality (terminology changes, shifting of levels in domain hierarchy etc.). When there is a pressure to ship we add a new mapping without touching existing naming, and slowly the domain names in the system exhibits a tangled relation with the actual domain.

That's just been my experience, and so I'm here learning me some good old OCaml and being very happy with what I'm getting out of it.

There's this great blurb:

We're a bit saddened to see that some of our customers integrate Coinhive into their pages without disclosing to their users what's going on, let alone asking for their permission. We believe there's so much more potential for our solution, but we have to be respectful to our end users.

https://coinhive.com/blog/status-report

It'd be awesome if someone did a comprehensive breakdown. If you scale this up to remove ads from 10% of the net or 30%, does it stay valuable with that mining power added to a single coin? Or does this business model require the continued pump and dump of worthless coins? What kind of energy and workload is this putting on user machines (in many cases without permission)?

If I run across a site that is mining without notice and permission, I'll never visit again, as best as I can. I don't want to support that. Hosting websites is relatively cheap, if companies weren't writing such bloated software, their costs would be much lower. Fix that first without adding more junk to the tech community, please.
