Dark matter seems to interact with normal matter only through gravity, but, based on the way known particles interact, theorists think it’s possible that dark matter might also interact with itself.

If dark matter were to interact with itself (as regular matter does), wouldn't we expect it to clump together and form the same structures as regular matter does, especially given that there's supposed to be much more dark matter to interact together than the regular stuff? AIUI one of the defining features of dark matter is that it doesn't clump together.

These systems are good at picking up small portions of copyrighted works within some larger context, but to guarantee that 100% of a YouTube video or scribd document is in the public domain is a different problem.

For published works like the Mueller report, one wouldn't need contentID. Matching the document's hash would suffice.

It's one man's work of passion. When I went, it was quiet enough that an attendant guided us around the entire first floor personally. It's not exactly tiny, but it's just two narrow floors behind an unassuming frontage, and so a big change from the other (public) museums in Tokyo.
Cool!

Having gone through this pain last weekend, I’m a bit wary of examples that are roughly stateless (or at least only do copying between channels). To all rust folks making samples: if you can mix in even a bit of mutable shared state (like a counter, logging, etc.), it goes a long way to showing whether your system can handle scoped threads/tasks, shared state, and straightforward concurrency ergonomically.

If you compare and contrast the docs for crossbeam’s scoped threads, Rayon’s scope, and an attempt at DIY via raw thread::spawn, I think you want to see the same clarity on the future/async/await side. Richer examples can really elucidate the pros and cons of different paths.
Anything which is published before your filing date is prior art. Something sitting in your garage that only you and your drinking buddies know about or something your coworkers have been chatting about on a whiteboard at the office is not prior art.

This also means that if you want a patent you need to file a provisional application before publishing your work anywhere (e.g. the other commenter’s YouTube example). https://en.wikipedia.org/wiki/Provisional_application

Having a first-to-invent patent system makes patent disputes into complicated messy legal fights about when different people first encountered an idea. First-to-file leaves much less ambiguity.
Europe is irrelevant. By 2050 it's estimated that Europe will only account for 9% of the global GDP [1]. Down from 15% today. China will account for 20% of the GDP and India 15% by 2050.

I can not understand the Hacker News focus on European law given its declining prospects.

This mirrors how open source hardware manufacturers can do a great job even with knock offs on the market. The Prusa 3D printer is open source, but all the clones are cheaper and lower quality. The expertise that goes in to building the Prusa is what makes them worth their higher price.

It's strange that ms got busted partly for their handling of internet explorer, but at least on windows there was never any restrictions on what 3rd party software was allowed and no obligation to pay Microsoft a 30% tax on sales. Meanwhile Apple has 50 pages of App Store Review guidelines, routinely rejects apps for political reasons. And collects taxes on everything.
This article is conflating two separate things: Apple said it should pay less for Qualcomm’s PATENTS. It always liked and never really said bad things about Qualcomm’s MODEMS. Patents != modems.

Also, the article quotes “Adam Mossoff, a law professor at George Mason University” without disclosing that Qualcomm funds GMU exactly so it will get favorable press like this.[1]

I expect better from WaPo.

> technical founders who love coding and avoid doing everything else.

the truth is that these tech co-founders are really looking for a playground to have fun with code/tech, the same way a kid wants to play lego.

Building a business is not fun at all. There are tonnes of mundane stuff, and these are fairly important. A technical co-founder is quite likely to have quit their previou job because they want to create an environment where they aren't restricted by the "business people" for doing technical exploration and play.

This is why i think finding a business partner who isn't technical is quite important. They can reign you back in.
Why? If someone like UMG or Disney steals their work do you really believe they will be treated fairly?
This seems like a good idea, until you get to interconnected systems that everyone depends on (like eg. the levees around an island, or a large harbor). Then it's STILL a good idea; in those cases everyone should pay!

This is one of my dreams! I own an awesome 67 Pontiac wagon which is a lot of fun, but after decades of riding in modern vehicles you just can't help noticing how much louder and smellier everything is with an old carbureted v8. It's wonderful to be able to pop open the hood and make sense of what's going on in there, but I'd still trade that engine in a heartbeat for a quiet electric in the same exterior.
Along the same lines, I think humanity's downfall will be its never ending appetite for complexity.
Non-term life insurance seems a good counterpoint. The price of the insurance may equal effectively a second mortgage over some timeframe but it can be priced.

It took me a long time to shake this line of thinking. Some things just won’t and don’t have to be perfect like that. You can’t store files in a DB, and you can’t be atomic across multiple systems like, say, a DB and a file system. It’s better to just figure out a working solution, like content address storing your file so that retrying is idempotent, then updating your DB once you’ve stored the file.

Why should they be difficult?

We absolutely want to discourage (ideally prevent) incorrect takedown requests, but correct takedown requests are a good thing. Beyond the fact that IP owners have the legal right to prevent unlicensed distribution of their IP, the only way a platform like Scribd can avoid becoming a haven for piracy is by handling takedown notices. If Scribd did not handle takedown notices and became rife with copyrighted content, they'd end up getting sued out of existence. The fact that they respect takedown notices is what keeps them immune from the lawsuits.

No it isn't. It’s because no one speaks Mandarin and Chinese music and movies are dreadful by comparison. One of the hardest things about studying Chinese is finding media to watch to improve listening comprehension that are actually enjoyable to someone used to Western levels of quality in production, writing and story telling. Khatzumoto of AllJapaneseAllTheTime.com took s break from learning Mandarin and learned Cantonese instead because the corpus of good movies is better, and it’s mostly pre-handover Hong Kong stuff. Widespread censorship leads to terrible movies.

I live in China and I’d say it’s plausible that people watch more Japanese, Korean and Anglophone media than Chinese, dubbed and subtitled. I wouldn’t bet on it but it’s at least 30%. Chinese tv and movies are dreadful.
In February, Arkansas eased restrictions on municipal broadband. I had a quick look at the text of the bill, and it appears that municipalities must get grant funding as opposed to issuing bonds or using general funds.

This Citylab story was recently submitted to HN: https://www.citylab.com/life/2019/04/arkansas-internet-munic...

A somewhat related development in Arkansas is electric co-ops, which were started to provide electric service to rural areas, starting telecommunications subsidiaries with rather firm plans to build FTTH over their entire service area. Several of these have been started in the last few years. Arkansas could see some remote rural areas without paved roads or public water get symmetrical gigabit internet before many urban centers.
In the 90's Windows had > 90% marketshare of the desktop market and Internet Explorer had > 90% browser marketshare. Globally, iOS is < 25% marketshare. So while Apple holds an app store monopoly on their own phone, you have a comparable alternatives available. Microsoft lost because, "The Court has already found, based on the evidence in this record, that there are currently no products - and that there are not likely to be any in the near future - that a significant percentage of computer users worldwide could substitute for Intel-compatible PC operating systems without incurring substantial costs." In retrospect, that looks questionable, but at the time Windows dominance looked pretty unstoppable.
This. I was surprised article doesn't mention it but its just an amazing place to visit. The so-called "Monument to the Conquerors of Space" is unlike anything you may ever encounter elsewhere and that itself is worth a visit. You cannot possibly stand under that monument and not admire the massive courage, perseverance and ambition of these trail blazers. This monument is so huge that its hard to even capture in single frame and if you manage to do somehow, photos don't convey its full magnificence.

Not doing it incurs a fairly large cost across many areas of the economy. Time has to be spent by people faffing around with this nonsense that creates no wealth economically and this essentially creates an overall drag on profitability across most of the economy, parasitically favouring only small sectors such as legal services.

The trouble is, this is a group profit motive and people seem to think of profit motive mostly from an individualistic and zero-sum perspective.

Storing legal contracts associated with accounts. I implemented a system like this. Documents were simple and usually small, pure html with no images or hrml converted to PDF, occassionally it was an attached JPEG from something someone emailed or faxed.

If you want a system where the documents are strictly linked to the account, easy to query based on account, consistent (in the DB sense), replicated and backed up with all the other very important customer info, and local so you aren't exposed to external risk factors it's the path of least resistance, and can be easily and securely implemented with very little effort.

Different solutions for different needs.
While I get this desire I have a hard time imagining ever using a free/open OS of any kind, mobile or otherwise. Mobile OSs and platforms tend to prioritize things that are unimportant for most users’ day to day use and thus suffer accordingly. They make good thought experiments or are great for the areas they’re optimized for (see *nix), but not for day to day use.

Perhaps if Apple really transitions to ARM on the Mac Line, that might be a reality in a couple years. I'm not sure they would want to replace x86 for the 'Pro' Desktop machines, but I don't think an ARM Mac Mini is out of the question.
Timeline of Mathematics
I'd say that you can safely ignore CT until you find the need or desire to learn more. The field is still very young and it probably shines most within pure mathematics, for now at least.

I think of CT as the study of "composability" in its purest form. Mathematicians are finding that this language is really good at translating domain-specific knowledge between disparate fields, not unlike the babelfish from the Hitchhiker's Guide.

FWIW, some researchers are apparently finding interesting applications in the development of biological models. John Baez has talked about applications in this direction via control theory [0].

Ask HN: Solo content businesses that are profitable?
Hi HN,

Who's had any success building building a profitable content business as a solo founder or side project?

I'm asking this because I just saw a similar thread here about SaaS and wanted to contribute but my project is a content site.[1]

I've had modest success and would love to learn from some of those of you who are a bit further along!

[1] I did write the CMS for the site myself, though... for better or for worse though.
We've banned this account for breaking the site guidelines. Could you please not create accounts to do that with?

They would probably be good for servers if Apple cared.
I'll start! My project is called Alchemist Camp (https://alchemist.camp). I believe I've made more free screencasts for learning the Elixir language than anyone else online, but I also put some behind a paywall. It's a side project that I spend around 10 hours a week on.

I started putting screencasts on YouTube at the end of 2017 and started charging last summer. My revenue is somewhat erratic since a large percentage of my customers sign up on an annual plan, but it's been covering my rent since the end of last year. My goal is to hit a baseline $2k MRR within the next 6 months.

The biggest challenge right now is that I started a lot later than my main competitors did. As a result, my site simply isn't on a lot of the lists, many of which include badly out-dated resources that don't compile with current versions of Elixir. There are always ways to improve the product, but I've probably underperformed more on the marketing side.

Longer-term, the popularity of the Elixir language itself is also a major consideration.
Right; the probable sentence is much lower, but how much lower is to a large extent up to prosecutorial discretion (8 levels), no? Levels 2-8 (taking 2-8 levels off 10), with no priors, would be guideline 0-6 months, if I'm reading this table correctly.

Consider that you may be turning people off the product: I had run into this service before (as a job-seeker) , but gave up simply because I couldn't actually drill down to anything meaningful-it didn't offer anything above browsing job boards. Even with a small # of offerings, AND logic allows people to filter down to what they are actually seeking. Providing a ranked list that grows the more specific I am being is, in my mind, negative value, since now I have to sort through a longer list of results that likely don't match at all. There's nothing wrong with providing a page that states "there are zero results for this query, but if you relaxed {X} then there are {y} employers avaliable.
Maryland ranges from quite wealthy near DC to quite poor in Baltimore, and very rural in much of the state. (It’s also more populous than Denmark or Norway, which gets compared to France all the time.) This data is a bit old, but it shows the Washington metro area (I think the fairest comparison to Paris) having a 50% higher GDP per capita than the Paris metro area: http://www.demographia.com/db-gdp-metro.pdf. Paris is comparable in income to second-tier US cities, like Cleveland.
When this phone dies I probably won't get another one. Someone gave me their old cracked phone. It would otherwise be garbage and I won't buy a new phone because the whole system is killing the planet and human beings in places we can't name.

It's so gross, I don't want to be part of it anymore.

So I think you're not going to change my mind about this.

Until we start saying no this can't happen anymore. It will keep on.

We are all culpable.

I like the visual design of the desktop as well as the website for it. The choice of key bindings seems good too — I like that the app launcher is bound to win+space, because I’ve always mentally thought of it as being similar to apple’s OS X finder. The documentation seems well written and should get people on their way. Hopefully this gets some people over the learning curve of i3 and into a place where they can enjoy its great power and minimalism.
> I don't ever recall seeing a 2 handed bronze sword, and if the steel is worse than bronze, why didn't they go back to that?

Bronze fell out of use not because iron/steel was better but because tin was rare and hard to come by. So, I'm not sure of the exact answer to your question but I suspect it's some version of "because they couldn't".
Not always true. People have various reasons for using throwaway accounts, depending on the context.

HN's guidelines don't prohibit throwaways; they only discourage routine use of them:

Throwaway accounts are ok for sensitive information, but please don't create them routinely. On HN, users should have an identity that others can relate to.

It may be right that the throwaway account you replied to was gratuitous, but it's not true that they're only ever used for low-quality comments.
Just because Trump lost popular vote during last elections does not mean that the result would be the same if there was no electoral college. The way elections currently work is discouraging many voters from participating: if you are a Democrat in red state, or Republican in blue state you might feel that your vote does not matter and not go to vote at all.

If there were different rules voters would also behave differently. So we won't ever know who would win such elections until we actually have them.
well is it a market that just naturally high barriers to entry so the market will trend towards oligopoly or monopoly, or is it caused by senseless regulations, protectionism, etc.?
Apple's mistake is not putting the membrane over the keys instead of under it. With the engineering that's already gone into the keyboard, just go the rest of the way and make a membrane keyboard that has good tactile response.
I've never understood this advice. To me it just makes a lot more sense to store everything in the database - much less complexity.

What I've done in the past is just put a CDN in front of the file url, so the file content is stored in the db, but served from the CDN.
The issue seems to be skewed incentive towards false negatives vs false negatives. If leaving false positives (materials being taken down based on a false claim) give much lower risk to the platform than false negatives (materials that should be removed but has not been removed), they would naturally prioritize reducing false negatives.

Churches literally aren't able to address "street problems" like violence and mental health problems. Governments are the best place to deal with problems where push actually has come to shove.

There might be some creative way to make sure charity-oriented churches are better supported by social service organizations, police departments, etc., but if that sort of setup exists now, it isn't routine or well publicized.

1. In meetings, Nathan provided the author with technical questions for her to ask out loud

2. In meetings, Nathan asked the author technical questions instead of asking his other teammates

3. In meetings, Nathan declined to answer technical questions even when he could, instead asking the author
