Hi Tonjé,

This is a great idea, but how do you protect yourself from Netflix and Amazon simply deciding to eat your category? It seems like as the 800 pound gorillas in the market, there's nothing preventing them from simply beefing up their catalogs and adding some categories to do the same thing.

FWIW, Amazon does offer Middle of Nowhere (the film in the article screenshot) for rental (no free streaming with Prime) and the "Customers Who Watched This Item Also Watched" is all African-American films as well. That said, it's not clear how deep their catalog goes, and they don't actually have an African-(American) category one can browse.

(Also, why did you write your last name in ALL CAPS? I've seen people do this before, but I've never understood what the convention is trying to achieve).

Hi! All the best for this!

One small question, why is the website in french? I think this product can have global audience, even better no?
I don't get how Netflix-of-$NICHE can be a long term business. It seems that once $NICHE-stream demonstrates sufficient demand, Netflix can simply license the same content and provide customers with a superset of the content that $NICHE-stream provides.

It's also unclear to me that Netflix is even lacking in this specific niche. My ex-girlfriend loved browsing my netflix over a VPN because it had so much of her african american comedy. (Admittedly, what she - an African woman - considered a good selection might be different from what westerners consider a good selection.)

In a few cases, e.g. Parables ($NICHE=devout christians), I can see how they offer something different - they deliberately exclude content (e.g., movies that offend christian sensibilities) that their members don't want. But that doesn't seem to apply here.
You have this exactly backwards: you are guaranteed to lose 0.5 cents/transaction. Suppose the price is $1.00 so you hold 100 shares. The price move up to 1.01 so you buy a share (at 1.01). Now the price moves back to 1.00 so you sell a share (at 1.00). You just lost 0.01.

There is no algorithm that guarantees you will make money in a fair market. The only way to guarantee making money is arbitrage or trading on inside information.

How is the car going to park itself? The grandparent's point was about how annoying trying to find a parking space is.

Can self-driving cars parallel park yet?

Can they detect a strip where parking is only allowed between 9-4 and it's 4:30? Can they detect fire lanes?

EDIT:

Also, are these automated taxis really going to be more affordable than owning your own car? Taxis are incredibly expensive today. Sure you save a lot of money when you don't have to pay a driver, but is it really enough to make car ownership undesirable?

Good article. Modeling FoW is one of the classic hard problems in wargame design, especially for boardgames, where the options for hiding information from one player without hiding it from all are limited.

The problems with "Good Guy" FoW go a little deeper than the article indicates, though. It correctly identifies human error (a platoon leader misreading a map, for example) as one reason why a commander's intelligence about the status of his own units may be incorrect, but there's other factors that can cause such problems as well, such as:

- Communications latency: the time between an order being issued and its being received can be significant, and lead to units following orders that were based on a situation which no longer exists, or disregarding orders because by the time the orders arrive the situation looks different to them than it did to HQ

- Subordinate initiative: lower-ranking units have their own leaders too, and those leaders have free will just like the Big Brass at HQ does, which means that sometimes they take action on their own authority, either in the absence of or in contradiction to existing orders

A textbook example of the latter problem is Union general Dan Sickles' advance on the second day of the Battle of Gettysburg (see: https://en.wikipedia.org/wiki/Battle_of_Gettysburg,_Second_D...). Sickles' corps was part of the long "fish-hook" defensive line that the overall Union commander, Gen. George Meade, had formed his army into after the Confederate assaults the day before. But, seeing slightly higher ground in front of his position, Sickles on his own authority marched his corps forward to occupy that ground. The result was disastrous; Sickles' troops were too far forward for the rest of the Union line to support them, so they were smashed when the Confederates hit later that day.

This type of thing is extremely hard to model in a wargame, because ultimately players want to feel that their winning or losing is down to the decisions they made, not due to random factors or the game itself pushing against them. So, while balky subordinates like Sickles are not uncommon in real life, how do you model that in a way that doesn't make the player feel that the game is essentially playing itself? It's a sufficiently hard question to answer that most designers don't even bother to try.

That's kind of like saying "If you could travel faster than the speed of light..." Paying without an upper bound is no less a violation of the laws of physics in a finite universe.

Your peripheral vision can see stuff coming from the side quite well.
>Then he talks about corporate monopolies (anyone who's read economics 101 would tell you corporate monopolies are rarely result of unadulterated capitalism, but rather state corporatism).

Let's talk about this point as a whole. Firstly, I don't think it is well substantiated, and there are numerous examples to the contrary- Microsoft, Standard Oil, United Fruit, telecoms, airlines, railroads- almost anything which requires significant initial investment to grow. But, more importantly- why distinguish between capitalism and what you call "state corporatism"? The corporations who lobby the state, or coerce the state, or even cause the formation of an authoritarian state in ways that work in their favor are merely being good capitalists- they're simply better at competing than other capitalists! When United Fruit coerces the US government into supporting a foreign coup, or a corporation coerces the police or military to massacre striking workers, or big oil asks for huge subsidies- it's no different from a capitalist perspective then investing in advertising or aggressive expansion, and all are about increasing control and centralizing power. If there were no state corporatism, how long would it be before a capitalist caused it to come about? Campaign finance laws, monopoly regulations, and public opinion can be rolled back or simply ignored until power is consolidated; the inherent unequal distribution of power in capitalism means that a comparative few people will always be capable of doing this. In the words of Woodrow Wilson: "If there are men in this country big enough to own the US government, they are going to own it". State corporatism, monopology, and inevitably authoritarianism are the end game of capitalism, not a perversion. You can't put limits on the definition of capitalism so that the second anyone is any good at it, and the most obvious oppression that being good at capitalism causes is then apparent, that suddenly it's "not capitalism" anymore because they didn't play by your rules in a system where the actual rules are what those with money say they are. Hopefully, this should make you more critical of the inherent viability of capitalism.
Some might suggest that imperialism is the highest stage of capitalism.
Plagiarism detection programs: Why are they all ineffective?
Interesting. I find the skills sections to be really helpful. I understand that the signal is not official and not a certification of any type, but the endorsements give me a sense for the extent to which someone is known by their peers and colleagues for a certain expertise. That's useful when I need to get up to speed on someone very quickly (e.g., when they got CCed onto a call with me and I don't know who they are).

Of course, you're assuming that the undercover drug lords are intelligent. Is this the case? Have they figured out how to make efficient use of the information resources at their disposal? Intriguing question.
Hoarding guns makes it easier for some people to sleep at night because they think that the government is going to come for them, or they are preparing for the fall of civilization.
I think I might go so far as to say I don't really think either of you know what you are talking about. Monopolies are created by barriers to entry into a market, this can include things like state regulation, but also things like intellectual property, and capital. Monopolies distort the market, but are not always net negative. Perhaps a good example are silicon wafer manufactures (technically an oligopoly, but the same arguments apply). Because the startup cost for silicon manufacturing is so high, and the infrastructure takes time to build, supply does not have to, and regularly does not match demand (bad). That said, the scales of economy involved with allowing a single company to produce so much silicon in this case makes that trade off well worth it.

I think it's silly when people use monopoly as a synonym for bad. Sometimes monopolies make sense.

I don't have specific examples, but I know that it's possible to read signs easily, (as in you can write a program to do it yourself with no great techno-wizardry,) and I don't see any reason they couldn't use that data.
The problem with Greece isn't capitalism, that much is obvious. The problem is the EU was designed to fail. It was created in such a way to appease the dominant economic countries by guaranteeing the EU would not be a transfer union. This all but doomed weaker economies from the get go.

Tied to one currency they lost the most effective means of combating budgetary and economic issues. Worse, as they become weaker it becomes ever harder for them to generate the hard currency they need.

So if anything what happened is exactly the opposite of capitalism, they could not compete because the rules agreed by governments prevented them. Yes Greece shares fault for working the books but the EU was formed to only favor the powerful countries and protect their interest, this was no union
Formally: monopoly power is controlling 25% of a market.
It simply relies on the Voting feature of ETCD (Raft) it's really simple to use locking with etcd, and etcd is really really stable.
However it would be easier to install etcd on every Postgres node and just make a golang library that sets the master of Postgres to the etcd master (etcd also has a leader). Also systemd would keep the overall system healthy. (that's what we at envisia do) Just have repeatedly check if the machine is the leader and if yes it sets the url of the currently running machine to a etcd key. So overall we need to use 3 Postgres machines and 1 could fail and we would still have voting, however thats just for a single master where we don't need to read from the slaves, however thats easily extendable.

Oh and here is the Compare and Swap (Atomic) functionality of etcd that he described: https://github.com/coreos/etcd/blob/master/Documentation/api...
wbhart got the gist of it.

Here's an even longer version of the rules:

Click/tap numbers to connect them to a chain. You can only connect numbers that are at the left, right, top, bottom of the last selected number. As a faster alternative, you can also drag/swipe through the numbers.

When the sum of the chain ends in zero (ie. sum % 10 = 0) you get rewards and side effects depending on whether the chain's length is composite or prime.

- if it's composite (e.g. chain length is 4, 6, or 8 digits long), you gain 2 seconds on your time for each digit connected. However, each digit also gives you a 1 in 4 chance of replacing a digit in the grid with a "blocker", a cell that cannot be selected.
- if it's prime (e.g. 2, 3, 5), you only gain 0.5 seconds for each digit, but instead of spawning blockers, each digit now has a 1 in 5 chance of removing a blocker in the grid.

Either way, the point value of the chain is ((sum / 10) ^ 3) * 5.

So connecting 1-2-3-4 gives you 5 points and 8 extra seconds but has 4 chances of spawning blockers. On the other hand, connecting 9-3-8 gives you 40 points, 1.5 extra seconds, and 3 chances to clear blockers.

Game ends when the time runs out. The goal is 1 million points, but the game will not stop you from playing when you reach that point.

Scientist develops model for robots with bacteria-controlled brains
There are a number of unexplained phenomena, easy to forget about but nevertheless essentially waiting on "new physics" to model.
I think you're probably right about the concept, but I didn't know that it was "a thing" until the documentary The Fog of War[1]. Excellent retrospective about Vietnam.

Like a lot of designs that use Raft/Zookeeper/Paxos/whatever as a building block, the full system doesn't inherit all of the safety properties of the underlying consensus algorithm. I don't think that makes this code useless by any means, but I think it's important to be aware of the edge cases.

Consensus algorithms are popular because they're supposed to solve the difficult problem of guaranteeing consistency while attempting to provide liveness, in the presence of arbitrary node or connection failures. Etcd itself can provide this for operations on its own datastore, but that doesn't mean it can be used as a perfect failure detector for another system (which is impossible in the general case). In particular, if the database master becomes partitioned from the etcd leader for more than 30 seconds but is still accessible to clients, boom -- split brain.

(You can attempt to mitigate this with timeouts, but that's not foolproof if your system can experience clock skew or swapping/GC delays. Exactly this kind of faulty assumption has caused critical bugs in e.g. HBase in the past, turning what would otherwise be a temporary period of unavailability into data loss.)

EDIT: If I'm reading the code correctly, compose.io doesn't make any attempt to mitigate this failure scenario. If the Postgresql master can't contact etcd, it continues acting as a master indefinitely, even after 30 seconds have expired and another server might have taken over. This appears to be what happens in the "no action. not healthy enough to do anything." case in ha.py. I'd be happy to be corrected if there's something I'm missing.

Wouldn't another fix be public financing of campaigns and a ban on contributing private money to elected officials in any capacity?

This is the "pipeline excuse" for why various groups are underrepresented in so-called technology jobs.

There is certainly some truth to this. On average some groups receive poorer education than other groups and one would expect them to be underrepresented to this extent given hypothetical fair hiring relative to their proportion of the general population.

But the question is whether some groups such as Blacks and Hispanics are underrepresented relative to their percentage of CS or other engineering degrees for example. USA Today published an article on this:

http://www.usatoday.com/story/tech/2014/10/12/silicon-valley...

It may furthe be added that in many contexts technology employers claim to be desperate for "qualified" technology workers, though they are vague about what "qualified" means. They often seem to imply that a CS degree means qualified.

In fact, technology companies appear extremely picky about who they hire, often informally citing "cultural fit" which is clearly not about technical qualifications despite the high profile statements that the problem is strictly technical qualifications.

In some respects, the technology industry is very diverse with many people from all over the world and many ethnic groups. It is certainly not lily white or even close. It is not NASA mission control in the 1960's with white male engineers with buzz cuts as far as the eye can see. Even the official diversity numbers from the companies, taken at face value, claim about thirty to thirty five percent are "Asian," most of whom would not be classified as white by most people. However, there are various groups, ethnic and otherwise that are rare.

The pipeline is only a partial explanation, one the company's promote because it absolves them of any responsibility.
Not a physicist or a scientist, but I do follow the news, and I think there's a lot happening 'under the surface' with people working on mathematical foundations (category theory, complexity theory, homotopy type theory) that are going to surface into physics in unexpected ways in the fairly near future.
I find the article lacking. Author makes a bunch of controversial yet unsupported statements. Even if they're true (something he doesn't really bother proving), the logical links from one to the next are missing.

The use of malware itself isn't really the legal reason why this is questionable. You can get a warrant to hack someone.

Just like busting down a door and taking someone's stuff is burglary, but a cop can do it with a warrant.

The legal reason for why this is questionable is because typically the judge can only issue warrants for people or places inside their state. The problem is that the rule was written before the internet.

It totally falls apart with TOR because law enforcement and courts can't even figure out where the server is. So this leads to an interpretation of the law where no court in America can issue a search warrant on a .onion address. That is absurd. There is no policy or legal reason to justify giving someone like a child porn distributor a free pass merely because they use TOR.

I'd actually argue that the search is valid if the state has a TOR access node located within it because the .onion address is what is being probed via TOR. It's essentially acting on behalf of the server. But many would disagree with such a broad reading of the rules. And it would be hard to draw a line between TOR and an old ISP network.

No, monopoly, market, or pricing power (the the terms are equivalent in anti trust law) exists when there is a range in which an entity can increase prices without losing sales to competitors. There is no percentage of market threshold.

This definition reflects the economic concept of a monopoly in that the presence of this pricing power indicates the absence of a competitive market with perfect substitutes for the goods sold.
I don't disagree, but keep in mind that on the large codebase you want to avoid false negative in term of pep8 errors.. I.e. if every time you build you see 100s of errors, you start to ignore those.
