The sandblasting effect was observed during the Apollo missions.

Apollo 12 landed about 200m from Surveyor 3, an earlier unmanned lunar mission.

https://www.nasa.gov/mission_pages/LRO/multimedia/lroimages/...

The total amount of dust displaced per landing is estimated at about a ton, moving at 400m/s (900 mph), and travelling easily 3km, with lighter dust being blasted into orbit.

Alan Bean's mission gave us an absolutely unique chance to really measure this blowing dust. After landing, Pete and Alan walked over to the S3 spacecraft and cut off pieces that had been subjected to the intense sandblasting of their LM landing just 160 m away. As Alan rounded the large "Surveyor Crater" and approached the S3 spacecraft he said to mission control via radio, "I thought you said this spacecraft is supposed to be white." (Not exact quote - I'm going from memory here.) Mission Control asked "Why? What color is it?"

Alan said "It's brown!" This set off a lot of discussion back here on Earth. What did the lunar environment do to that spacecraft to change it from white to brown??? The leading theory was that radiation changed the chemistry of the paint. That theory held for 40 years.

Around me 2008 I traveled to Houston and officially checked out all the white painted pieces that had been cut off the S3 spacecraft and returned to Earth by Apollo 12.... We used Scanning Electron Microscopes, laser scanners, X-ray photoionization spectroscopy, and electron dispersive spectroscopy. We discovered the paint's surface was penetrated by sand-sized (100 micron) lunar soil particles travelling about 400 m/s. Each one made a pinhole in the paint, and we could see the soil particle lying in the bottom of each tiny hole.

That's not particularly true. I don't think there is a single mathematician whose papers are understandable to laypeople (by laypeople, I mean the average person, who remembers some but not all of highschool math). What's really going on here is that Einstein made a tremendous contribution to a tower that was already quite tall, while Darwin's contribution was to the ground floor where everybody could get on. The maths analogy to Darwin would be one of the inventors of Algebra - evolution is taught to children right along with the foundations of math and physics.

I don't understand why you feel like it's sad or pathetic that people would need a model to follow something you deem as common sense. I'm sure there are plenty of people smarter than you or I that think everything tech related is "common sense".

The whole point of a diagram for something like this is so that the people without 'common sense' can learn things that weren't instilled into them growing up. Is it really a pathetic situation for people to be teaching the unaware?

I get what you're saying in that it should be obvious, I think so myself! That is that anybody with my education and upbringing should understand easily. But if I look at somebody who grew up in a poor household and had the shit beaten out of them everyday by their parents and dropped out of high school, I wouldn't expect them to know the optimal way to behave socially.

That update option window says "max 18 hours". Doesn't help when leaving computer for 24 hours+ to render. The other thing is you might have critical work happening, and really don't want any risk of problems due to updates. So even if you're not using PC, you don't want updates to happen for a couple of weeks or longer until project isn't so critical.

The forced updates, even for advanced users, is the single reason I refuse to update to Windows 10.

I think the negativity becomes easier to understand if you put it this way.

GitHub earned trust from enterprise and open source community alike. Stable, robust, secure and reliable. Competitors try hard but they're not even close. Everyone's happy.

One day, they announce, they are bought up by a rich, notoriously closed source software behemoth that was once sued for its monopolistic tactics. It claims its now a changed company wanting to empower developers to build the future and the only way they can do that is by buying GitHub and promises to do their best work to empower every developer to build, innovate and solve the world’s most pressing challenges.

4 months down, they declare they've built a close integration with a proprietary, overpriced issue tracking tool that is described as slow, terrible, unproductive, confusing and an utter nightmare by its users.

> both US parties are weirdly on board with continually extending the reach of copyright and IP laws

I don't think it is weird considering that US is a mass-exporter of Intellectual Property. Hollywood is big global business. It is good for the US economy if other countries respect the copyright laws and are willing to pay for movie-tickets.

US is also a massive software exporter. I don't have the numbers but we know US has Oracle and IBM and Microsoft.

Think about Intel and AMD, without copyright their processors could be copied by anybody and pirated and sold much cheaper.

What's the best length for copyright protection is a different discussion, I agree that "Monopolizing works for most of a century after the life of the author is bad policy." But I don't think it is weird that countries which benefit from it would support longer terms and better IP protections in general.

>> Most Prologs do something approximating a naive depth-first search with unification, and on complex search problems this approach rapidly blows up.

Most modern Prologs use indexing on predicates' symbols and arguments to speed up queries and the days when Prolog was a "slow" language are long gone by.

As to the search strategy, it's a bog-standard, depth-first search (no approximation). Unification is part of the theorem-proving algorith, SLD-resolution. Depth-first search is used to find "resolvents", i.e. candidates for resolution (ish).

The parent post describes a backward-chaining problem, where rules must be selected depending on their arguments, most likelly to perform some complex reasoning procedure. In that context, search is required to select relevant rules at each step of the reasoning process- not, say, to search a large database for all records of persons with a name starting from "m".

For this kind of use-case, Prolog's search is not only perfectly adequate, but also nearly perfectly optimised, due to long years of development as a language.

That said, "searching a database for all records starting from m" is very much like searching for resolvents and thanks to modern practices, like indexing, Prolog can do that kind of search just fine also.
Facebook’s Zuckerberg Tells Employees to Respect Diverse Views of Colleagues
Initially I really wondering about the intention behind this new style of messages (casual and personal, lots of "we"), but now I think they are trying to get people used to the idea of "operating system as a service". It seems likely that this is where all these "We've got an update for you, just sit back ;-)" style of messages come from. Curiously, the bluescreen talks about "your computer" having an issue, though, with a sad smiley, no less.
Even Python 3 makes it easy to ignore how things work. open happily accepts a string. Regex works on bytes. open and the standard streams can be used for reading and writing without explicitly specifying any encoding or error handling strategy. There's a default value for encoding on codec.encode and codec.decode. And nothing is checked statically, so you get to discover all your mistakes at runtime—and often only with a specific combination of inputs and environment.

People don't think about these things because Python encourages you to ignore them. Until it doesn't. There'd be a lot less confusion if Python 3 were more strict/explicit about conversions.

With a traditional newspaper your readers are footing at least part of the bill for the articles

Back when I used to pay for a physical newspaper thrown at my door, I remember it often said that the price covered printing and delivery and most of the newspaper's income came from advertising. Was this wrong? It doesn't seem like it... it was sub $1 per issue, which seems about an order of magnitude less than what Amazon would charge.

I wrote this response because my experience so far is that, while not discounting his twitter antics, Elon is a force of good in this world and is mostly sincere and there seems to be a lot of fud (fear, uncertainty, doubt, often unsubstantiated or just quoting lies) spread around whatever he's doing.

Some sentences or terms you use may be factually correct in some context or way, but you seem to be painting a pretty negative picture chaining them together.

Granted, the media also occasionally report on Tesla kicking ass, but the negative press coverage almost seems like a concerted effort to spread fud every chance the media gets. The media have a vested interest in selling drama and they blow shit out of proportion and created issue where there isn't any.

They misuse their responsibility of shaping public opinion when they for example go crazy on someone taking one puff of a blunt and ignoring almost 3 hours of meaningful conversation with a sentence.

If Tesla is in such a precarious financial state and a sorry ass company, why do investors and banks keep lending and pumping money? Because the fundamentals are solid and anyone actually following the numbers and their mission, as opposed to media fud, knows they are about to skyrocket.

Their valuation may have been inflated especially if you believe the value represented the here and now but the fundamentals haven't changed, in fact they may be even better than expected. Once Tesla hits profitability on the account sheet (they already make close to 20% on every Model 3 sold but are 'losing' money because of heavy investment as far as I can tell), they will shoot to the moon because the media will then report Tesla is suddenly a good company and the optics have changed, even though the fundamentals haven't.

They're betting big on at least mid range Trucking switching electric because according to them it'll be cheaper to operate electric fleets. They got a pickup, the model y, planned to begin production soonish. They can lower their unit prices once they hit massive scales due to multiple gigafactories. They operate their own charging network, no other car manufacturer comes anywhere close to what they have.

Granted, Elon is the hype machine behind companies he's running or involved in, but his cult of personality is not all vanity. Why does Elon take no (1 dollar) salary, still holds some 20% of the stock and works his ass off and drains himself to his detriment on Tesla? Because he seems to be for real, a believer, and he delivers even if it's delayed.

Tesla under his leadership has done a great service to humanity, igniting the transformation to moving away from fossil fuels. The other car makers are lagging behind and only now starting to invest billions into battery manufacturing when Tesla is showing them they're for real.

I thought helping with load balancing and storing more volatile non-fossil energy and the creation of smart local grids and allowing people to get off the grid with their home batteries could be a reasonable endeavor for Tesla's battery division.

Ads are always disrespectful of their victims. They are intrusive and manipulative by nature.

Self respecting marketers will often say that their goal is to inform, but without fail, that "information" is laced and inextricably woven with manipulative psychology, tangential to the product being sold.

Further, in any industry where it can be employed, it chokes out every other form of revenue. How can anyone compete with "free"? Then, inevitably, when ads enter a space, they quickly dominate and poison it.

I'd start with looking at a sub-segment that you can reach within the larger roommate seeking group of people you plan to target.

Say people moving for work for example. I'd first pick an area that is fertile with people moving for work and seeking roommates. I'd then pitch this platform to as many work places that I possibly can. Give out stickers/pamphlets/freebies and ask them to be handed to new/potential employees or at least get them to recommended you to to such folks.

Next, I'd reach out to popular communities that are roommate friendly and do the same to try to get them to recommend your platform to folks seeking roommates.

Next, keep track of every lead, every post on CL/Reddit/Fb in that area of focus to gain some sort of edge or insight into your customers needs.

That should provide enough data to plan next steps.
