Warning: I am neither a skilled nor experienced programmer. I would say the kernel of programming languages is more practically something like C, assembly, or machine language. Kernel implies containing the core functionality, the building blocks. Van Roy's kernel language does seem to contain core ideas for ideal programming languages, even though it doesn't seem to translate well to existing hardware / machine language.

After reading a bit about it I started to think of it as pseudocode for programming languages, and I thought I'd share some results from my searching based on that idea [1].

"In terms of the kernel language itself, it is in fact its own programming language, a sort of "runnable pseudocode" that is executable in the Mozart/Oz platform."

Here's an interesting link I found by searching for database pseudocode [2]. This delves into the topic of "NoSQL", which might be helpful in your database basics research, but it also covers other database basics.

I am also not very skilled nor experienced with databases, but based on your request, one database that comes to mind for me is Berkeley DB. It is the building block for lots of other technologies, and is also considered one of the origins of the NoSQL concept. Here's a recent relevant discussion that probably made me think of it [3] (that and it is the basis for a distributed filesystem I'm studying). Also, check out the Wikipedia for it, and (maybe obvious to you already) searching site:news.ycombinator.com on Google can get you a lot more interesting discussions on any topic.

Here's one more random link I found [4], just because it has a lot of summaries on different types of NoSQL databases.

Again, this is all far from expert advice, which is probably really what you need, but I thought I'd just share with you what I found in my attempt to understand this "kernel language" concept and apply it to databases.

I've never understood why the American model of mixing academics with athletics came to existence. I understand why it continues, of course, since the status quo nearly always does.

The Australian(/European? I'm not sure) model of having schools only passingly involved with athletics, and then having the athletics clubs and associations as separate entities just makes much more sense to me.

First, it allows for amateur sports to continue well past high school/college, allowing those who compete for fun and fitness to do so. Sports, after all, shouldn't just something you watch on TV once you're out of school.

Second, apart from providing a fun diversion to students in much the same way as a video gaming club might do, why should any teaching institution be involved in sports? Surely that's outside the core mission.

Van Roy's book is an awesome way to explain computer languages and computing itself. I'm not sure there's anything so approachable yet mind blowing for DBs.

I think Foundation of Databases, "The Alice Book", lays out the mathematical basis well. The relational algebra might be the kernel language. I think Ullman's books on databases provide more implementation details. Caveat: I haven't finished either. The Alice book is pretty dense.

I'd describe it this way myself:

A database is a persistent repository of facts about some domain.

The simplest set of facts might be a set of values. You can't do much interesting with that. This might be main memory or a hard disk.

Beyond that, the facts might be tuples (K, V) where K is some name or key and V is some unstructured value. Key value stores and filesystems are like this. You can index K and provide fast lookups

If the tuple has more structure, it might be a relation. Relations might be described as an ordered tuple of values where each value is selected from some domain. (Name, Age, HourlyWage) might be a relation where Name comes from Strings, Age comes from Ints and HourlyWage comes from Floats.

So, we might have a couple facts like:
(Bob, 45, 14.50)
(Jill, 19, 112.95)
(Jim, 7, 1337.0)

Now, the repository of facts can provide a solver that answers questions. You define some constraints like HourlyWage > 100.0 AND Age < 10 and it finds the facts that match the constraints. It's more complicated than that and the Alice book explains the mathematical foundations well.

And the database remains a repository. You can add data to it. The repository may enforce the relations and reject facts that don't fit the domain of their values. Maybe it has uniqueness constraints on certain fields, etc. etc.

Beyond that it's mostly additional features. More complicated relational operators. Better query abstraction. Optimizations to solve queries more efficiently (query planning, etc.) Atomicity, Consistency, Isolation and Durability guarantees. Clustering and networked operations. So on and so forth in the spirit of CTM.

My intuition is that the mathematical foundation is fairly pure. So even "non-relational databases" could be viewed as implementing some non-standard form of the relational model.

How does opening more restaurants:

1) Allow non-local demand? Do people fedex overnight the food?

2) Significantly increase infrastructure load? Do people live at the restaurants when they're not serving food, and thus require schools, police, parking, roads, jobs, etc?

Even then, restaurants do create demand on the city, and they are managed via zoning laws.

A more accurate analogy -- claiming that high density development will bring more restaurant patrons, resulting in more restaurants opening, resulting in restaurant prices dropping.
Ask HN: I am underpaid and overworked – how much equity do I deserve?
<this is a throwaway account>
Background: For the past 2 years, I have been part of a custom software development company run by myself and two relatives, one of which owns 100% of the company. I've been quite severely underpaid for the past 2 years, but I had agreed to it because I knew the company couldn't afford it yet and I ultimately wanted to have equity in the company. I was under the impression that I was going to be part of a hustling team that would work together to build something great. In reality, the owner has effectively checked out and expects me and my other relative to run the company for him. I need to have a talk with him for how much equity myself and the other relative deserve, in addition to salary increase. The company has sustained positive YOY growth, but the actual finances and how the money gets spent is more of a shady subject.

How do you think I should approach this? How much equity does someone in my position deserve? I realize I haven't provided all the details, but any advice would help.

According to Akamai's State of the Internet report for Q1, the US has an average broadband speed of 11.9mbps. Romania is 12.8mbps, Poland is 9.8mbps. By comparison France is 7.5mbps, and Germany is 10.2mbps.

Based on the median household income in Romania being 16% that of the US, if 1gbps Internet access there costs $35-$40, you're paying the US equivalent of $210-$240.

I reject the premise that San Francisco should be planning for an ever-increasing population.

At some point I think that San Francisco should look at itself and say "Hey, we're a small, earthquake-prone hilly penninsula, we can't expand outwards. Traffic flow is constrained by planning decisions made a long time ago. We've got a pretty good quality of life as it is, and lots of nice historic buildings. Let's just put a lid on it and declare we're basically full".

Many of the nicest cities in Europe are ones where at some point in the past they've decided to stop building in the historic city centre and just leave things as they were at some particular point in time.

If anything I think San Francisco needs fewer people. San Francisco should focus on quality of residents, not quantity.

I meant Occam's razor as a way of explaining why they were handed over as paper - the simplest explanation being they were intentionally making it harder.

I get why the agency might print it out- but I don't get why the Clinton staffers would print them out. If the government is going to subpoena or raid me, they're just taking my computer. Sure, if it gets to public release, then they might print/redact. But they sure are not going to wait for me to print out stuff and hand it over.

Given the original 'two phones are too difficult' excuse for having the private emails, I can't see how printing out the paper and handing that over can be seen as anything but deliberate delaying. Unless I'm missing something here, it's not like the Clinton staff redacted the mails themselves - they just deleted the ones they didn't want to hand over.

If the agency staff are redacting for public release, then that is a different thing altogether, they could have done that from the original emails.

Ask HN: Startups – Make Money vs. Change the World
I've been following the tech scene for a while and it seemed like the general advise for future startup founders is to make sure you are really passionate about the problem you are trying to solve [1] and startups are supposed to "disrupt" existing business and "change the world". And if your reason for starting a business is just to make money, it seemed like you are destined to fail.
However, after reading some biographies of successful entrepreneurs, it does seemed like making money WAS the main motivation and they weren’t particularly "passionate" about the problems they were trying to solve. A good example would be Dennis Felix. In his book "How To Get Rich", he mentioned that the biggest myth regarding getting rich - “The first is the claim that people did not set out to get rich but became rich by 'accident'. 'Oh, I only did what I love to do and woke up one day to find myself wealthy.' That sort of thing. It may have happened. But very rarely in my experience”. From Paul Getty’s How To Be Rich, “Almost without exception, there is only one way to make a great deal of money in the business world–and that is in one’s own business.” And finally, From John D Rockefeller’s Biography, he was initially selling meat or some sort but changed to the refining oil business as soon as he realised that it made more money.

Thoughts?

It's really sad to see no mention of Valve anywhere in the article. The work that was done at Valve in 2012-2013 on VR hardware and software was critical to the success of Oculus. Valve created a complete VR demo that was shown to Andreessen-Horowitz near the end of 2013, and was a deciding factor in their decision to invest, as well as Facebook's decision to buy. At that time, the best hardware created by Oculus did not have 6DOF, high-resolution tracking. It did not have low-persistance, globally-illuminated displays. It did not have proper lens distortion correction. It did not have presence. Basically, all of the hardware factors that have made modern VR exciting were discovered and developed by the team at Valve. Unfortunately, Valve was not able to capitalize or commercialize all of this work, and basically just gave it away through a very awkward interaction. Source: I worked there on VR. Of course, they are now working with HTC on the Vive, which is really great, and is going to give Oculus major competition.

Where?
I'm from that land called Vancouver, BC. BC in general has NIMBY policies. The cost of construction is also higher. Maybe not as bad as the bay area, but enough to exasperate the problem. BC is also not experiencing a population boom fueled by an economic boom like SF is. It hasn't for the past 20 years, the SFBA has experienced it twice.

London and Vancouver are created by loose investor immigrant laws and tax incentives for the rich. You could get Canadian citizenship as an 'investor' by basically buying a house until very recently. On top of that, you get special tax treatment for the first several years of citizenship if your rich by Canada. Canada's real estate bubble never popped.

China has a large amount of ongoing capital flight, Vancouver is nice and stable, and a relatively quick flight back to China. Vancouver has a huge Chinese immigrant community. All of this combined plus the general Canadian real estate bubble & laws creates Vancouver.

---------------

London is even worse. In the UK they have a nom-dom resident tax law, where you basically just pay a flat tax of ~$40k/yr and have no taxation on your foreign income as a rich person. London is a hub city for the world too. The UK also has very low property tax rates. All of these facts combined create London.

If the UK wants to reverse London, then getting rid of non-dom tax laws, adding wealthy-only property taxes and treating them as normal tax residents will reverse the trend fairly quickly.

--------------

The USA is not an attractive place to be rich resident, unless your wealth comes from a US corporation. The USA has a high relative tax load, citizenship based taxation (only place in the world!), harsh anti-corruption / anti-money laundering laws, a very powerful, wealthy and motivated tax collection agency, a global financial surveillance apparatus, estate tax, a long and annoying immigration process and so on. All of this puts a damper on the super wealthy making another London.

Also the state of a place doesn't really matter, the 'investors' would be interested in molding crack houses. They have the money to turn it into whatever they want. You can do a total rebuild in SF as long as you keep the same square footage. One ancedote is a heavily molded crack shack in my neighborhood listed at ~$600k and sold for ~$900k. Like I was getting an allergy attack just walking into this place for a few minutes. Also see the same thing in Vancouver with this comedy game: http://www.crackshackormansion.com/

In summary: Build more, build tall, we need more 30 story residential apartment complexes! The laws of supply and demand do work! Ideally right beside BART and Muni tunnel stations. The mission became overpriced despite being a bad part of town because of BART.

What we need is more people capable of entertaining an idea without necessarily believing it. People who can acknowledge multiple possibilities and put reasonable plausibility ratings on them without getting too emotionally involved with any of them. People who can say "Yes, the widely accepted story is probably true, but here's five or six low-probability alternative possibilties."
I find it a bit bothersome when you start to compare SF to Tokyo. The fact that its subway only serves a bit more than 20% of Tokyo's rail traffic, yet at the same time is world top at daily passenger-kms, shows just how massive Tokyo's public transport network is. Earthquake safety have nothing to do with this, it's simply the ability and will to invest in public transport on a massive scale that's proportionate to population growth. I mean just look at table [1]. Japanese do a factor of 25 times the rail passenger kms per person compared to Americans. And I don't think Americans have a much shorter commute. Another way to put it, Switzerland, in total, with just 8M inhabitants, does 1.8x the passenger rail traffic as the whole US [2]. Just think about that for a moment. It doesn't matter whether you put it under ground, above ground or through somebody's swimming pool - any rail is progress in the US.

Edit: Another fun list: The world's 50 busiest train stations. Guess how many are Japanese [3].

> Our mission isn’t to connect a billion people, it’s to connect everyone in the world.

I wonder whether he is aware that Oculus has been moving away from that goal for a while now. They are now a company that works with Microsoft, AMD and nvidia on Windows-exclusive APIs and have dropped support for all other operating systems.

That's why all "social" VR applications for the Oculus Rift are a joke. Sure, you can get together in VR. But only when you use windows and only with other windows users. Zuckerberg says he wants to connect everyone. Right now Oculus is working on connecting Windows users exclusively. I wonder what Zuckerberg thinks about his newly acquired company acting this way.
While affordability is certainly an issue, the OP probably is probably referring to capital costs involved and whether Google can recover them back.
Thanks, that's a better link than I found. It also shows that the minimum combined salary over 3 years for a player starting in 2016 would be $450K + $540K + $630K = $1.6M.
