The problem here is not the technology per se. Technology is only an enabler.

The problem is that in urban areas in Asia let's say Heibei + Beijing 100 million people, Greater Tokyo/ Osaka 60 million people, Jakarta, Delhi, Bangkok each 10 million + people, inclusion is a massive problem. Here in Asia, exists tower sprawl where people anonymously exists for years. That is easily the birth-ground for anonymization which leads to seclusion and radicalization. An example are the Japanese hikkikomori.

On the mobility side, I just returned from Chennai. Lookup on Youtube traffic in Chennai. This is pure chaos. My company helps governments across Asia to plan better cities because through my data they know where and when people play, drive, park, go to events. That helps for healthier cities, because new streets can be build and parks and sports centers can be build at the right locations. We give data to justify millions of dollar in urban development.

See, drop!in for example is marketed as a travel app. But it provides a wonderful meta-data-source where events are happening and how many people go there. That knowledge can lead to better organization of public transportation to and from the events.

In addition, this app is community building by bringing in people with similar interest together who might have not met otherwise.

Btw, it might or might not interest you, but all apps are powered by the same back-end giving us the consolidated picture.

I actually would be scared of anyone being a sysadmin (or devop for that matter) and not know their system very well.

Also I actually think it's a community thing. What is way stronger in the BSD community is people not being missionaries and wanting to aggregate users as much as you see it in the Linux or MacOS world (not saying that's bad!!!).

If you join the BSD community and are like "Why would I use BSD" people will often will be like "Why bother, unless you wanna learn something new? If you don't have a reason for using it, we won't convince you". This is pretty unique to the BSD community.

That also means that you are expected to not as dumb questions.

I was active in both BSD and Linux communities, and even in the more "know your stuff" communities (Arch and Linux for example) asking dumb questions wasn't frowned upon.

Yeah, you may call this elitism. Maybe it is. I don't think so, because there is no "I am too good for answering this" and in general less politics, but then it of course you can't completely deny it, if you are supposed to adhere to the typical "How to ask good questions" guide.

And really, it's not that one is better. It certainly isn't. It's a different approach. It more likes me think of how I once watched the Standford Programming Introduction Class and the guy talked about how there is different courses and some are more about being nice and holding your hand at all time and the the other is more pushing.

It's a culture thing and just like companies are successful with different cultures you can't say one is better for everyone.

Also it depends on what you count your success on. And that can be so many things, having something stable, having great bleeding edge, having a large community, a smart community, having a few big success stories or having everyone use it.

One can maybe compare it to a business plan or describing target audiences. Nobody will say that the target audience is wrong. (even though that's more the case when your goal is to make money)
niftich's got a pretty good answer.

Most social network feeds are organized using machine learning algorithms. The ideal case is to see the latest non-trash content, but that requires the machine to interpret natural language / photos in the post. We're not quite there yet, so instead, algorithms rely on meta-data. I.e. views / shares, and match them to similar character models to yours.

This is one layer removed from the actual content, but in order to assess its entertainment value, it needs context, which takes time to collect. The results in delay in reaching your feed.
If you just want to update your system it's:

pkg update
pkg upgrade

Or just:

pkg upgrade

This will do mostly what apt-get does (unlike apt and more like many others) it won't start or restart services.

You also have stuff like autoremove, clean, which (for checking which package owns a file), etc.

The Christian Crusades were primarily a consequence of a complex geopolitical situation, a multi-century of clash of empires (in particular the Ottomans, Ummayads and the Byzantines) across multiple theatres from modern Spain to Jerusalem and beyond.

The real role that Christianity had to play in this clash was as the great unifier for a fractious western Europe wreaked by petty kings squabbling among themselves, turning their violence outward against common geopolitical foes rather than inward against each other. A pagan Europe would still have seen similar wars, it just would have had a harder time unifying to repel the encroachment of the eastern empires.

I actually find that the opposite works for most cases.
The best board games are the ones that are either a take on "common social games" or have a fairly simple ruleset.

The problem with complex rulesets is that they tend to make rounds very long which when you combine it with 4-6 players makes games drag for considerably longer than they need to be.

The worse games are the ones that try to mitigate that with multiple victory paths often partially RNG based or silly "sudden death" rounds after an arbitrary round count to force games to last no longer than 60-90min.

Sure you can point to games or systems like D20 but even then the core ruleset is fairly simple and uniform and the rest is just ad hoc that can be used rarely or not at all.

The one thing you need for a good board game is to have decent strategic depth with mechanics that induce interesting social dynamics, a lot of games try to implement the former by making it complicated by design and forget the latter.
Real maths is done either in books or papers, where the authors explain every bit of notation they will use. This is not the case in online resources, which is indeed a bad practice... But hey, don't blame maths for that.

And regarding the "understanding maths in terms of computer programs", sure that's possible to do with _some_ topics, but you just can't expect a computer to represent _every_ concept you'd like.
My friend is like that too, he also does it's own games... with complicated rules too haha

I prefer the most bang for the rules, they should be as simple as possible to let the game still be interesting
Perhaps Maths students will soon be studying the "Bridges of the Euro" problem, instead of the "Bridges of Königsberg" problem. That will solve two issues:

* the name Königsberg has not been used by most of the world for many decades. The city itself goes by the name Kaliningrad, although younger people often use the nickname "König" for the city.
* the bridge count in now-Kaliningrad is not the same as in the famous puzzle.

(Yes, yes, I'm trying to show off that I went to Kaliningrad and checked out as many of the bridges as still existed.)

Putin's Warning, Software Eats Government?
Domain-specific languages, notation, and vocabulary exist for many disciplines. They are for the benefit of experienced practitioners and allow them to express common concepts and ideas in a precise and concise fashion to those who have been also been trained in the art.

Sometimes jargon, abbreviations, and cryptic notation exist to artificially make it harder for outsiders to understand what's going on, but the examples in this post don't convince me. The true issue here is that the appropriate Wikipedia article has no link to the "Simple English" version.

Most humans are capable of using context to distinguish usage. Operator overloading in programming languages and in mathematics can be useful sometimes.

I was really surprised with the R&D number and thought it was incorrect since I knew the spending to be small. Just checked that in the last 2/3 years there has been a major upgrade in R&D spending.

Not sure where all the money is going though. There hasn't been any major breakthrough improvement in Apple tech to match the spending. Any big stealth project? What does everyone thinks?

Nice UI btw.
With the majority of articles about cutting edge science, very few HN readers would be qualified to state whether or not it's a breakthrough or bullshit. The option would protect HN from the bullshit, but it'd also hide the breakthroughs that people believed too good to be true. I think that'd be an overall drop in the quality of what we read here.
Show me a paper that explains "every bit of notation they will use"! ;P

(I understand there's a difference between "explaining" and "stringently defining", but I can't help thinking of the only book I know that actually tried to stringently define all notation: Principia Mathematica. If I remember correctly it took Bertrand Russel about 160 pages to define addition and prove that 1 + 1 = 2. :P)
>had Europeans been atheists

Silly counterfactual. A more interesting one would be if Europe had remained firmly Pagan instead of substantially Christianizing in the first millennium AD. In that case, one could imagine that no great religious alliances would oppose the Ummayad and Ottoman caliphates, nor would Byzantium hold out as long as it did... eventually we might be looking at an Islamic colonization of the New World, as the well-regarded Islamic traditions of science and scholarly inquiry ultimately discovered America.

A big question would be whether colonization and conquering would proceed at the same pace without the Spanish efforts, and if not, whether smallpox resistance and the like could have taken root and afforded the native American peoples a better fighting chance. And would the same ethnic groups be represented among the colonists? What slavery practices would we have seen?

In my experience people that are very verbose, that talk or write at great length and with ease, tend to have a dislike for terse formulations. Sometimes to the point of being offended by it. Math is just about the ultimate in terse notation and perhaps the author is one of these verbose people.

The same thing can be seen with programmers: The verbose programmer writes a lot of lines of code and is proud of it, while the terse programmer is proud to remove or simplify code.
Arguably it was the ratings agencies that should have been prosecuted.

They certified many, many unsafe investment as "AAA rated", when they should have asked questions.

The few people who did pick the crash did exactly what the rating agencies were supposed to do - they dug through the paperwork, found out what was backing each investment and saw how bad they were.

One might argue that they couldn't because they were paid by the banks. I say that is a separate issue to what could be argued was either careless or fraudulent behaviour.

> Most humans are capable of using context to distinguish usage. Operator overloading in programming languages and in mathematics can be useful sometimes.

No doubt about it! But the difference as I see it, and what the OP is complaining about, is that in domain specific programming languages it's always possible to find a definition for the notation (an overloaded operator is defined somewhere, and so on); whereas in mathematics the only real definition is in the head of a mathematician.

I have to agree with the OP, that sucks. :(
The raison d'etre for these kind of institutions is precisely to centralise power. So that matters of wider community importance can be agreed upon collectively and standardised. And we absolutely do have issues that need to be solved at a continental level.

The problem is that sometimes those institutions overreach into areas that should be handled at a lower level. Arguably the British Parliament is more guilty of this than the EU and has control of things that are much more important to everyday life.
What I'd really like is a 15" E-ink display with a good refresh rate. For coding and lookup up documentation at night or in the sun, that would be a pretty good setup.
Specifics tactics vary widely depending on the sector, but the general principle is this:

(x)^n

x being # of people you're able to reach (sorry for the nondescript language), and n being how many people each of those persons will share that tool.

Obviously, whatever endeavor you undertake should seek to maximize n. And it would also be good to aim for low cycle time.

MNIST Handwritten Digit Classifier – beginner neural network project
>Two, wikipedia refers to E(X) and E(Y) as the means, not the expected value. This gets even more confusing because, at the beginning of the Wikipedia article, it used brackets (E[X]), and now it's using parenthesis (E(X)). Is that the same value? Is it something completely different? Calling it the mean would be confusing because the average of a given data set isn't necessarily the same as finding what the average expected value of a probability distribution is, which is why we call it the expected value. But naturally, I quickly discovered that yes, the mean and the average and the expected value are all exactly the same thing! Also, I still don't know why Wikipedia suddenly switched to E(X) instead of E[X] because it stills means the exact same goddamn thing.

IIRC, the mean is the particular case of the expected value where the transformation function is the identity function.

The general expression of the expected value, where f(x) is the probability density function and g(x) is the transformation function, is:

E[g(X)] = \int{g(x) * f(x) * dx}

Let g be the identity function (g(x) = x), then E[g(X)] is the mean.

For example, let's say that you bet on a throw of dice such than you win 2$ if the result is odd, lose 3$ if the result is 2, and win or lose nothing otherwise. Here, the event X is the throw of dice: you have 6 possible outcomes. Your transformation function is the gain you get for each outcome, therefore g(x) is defined by:

1 -> +2

2 -> -3

3 -> +2

4 -> 0

5 -> +2

6 -> 0

Then, the expected value E[g(X)] can be calculated by summing all the g(x) multiplied by the probability p(x) for all x (all outcomes).

The first point of the article, in my opinion, is more about statistics than math in general, and I believe people find it weird because of the confusion between X and x, the former being a random variable associated with a distribution function, the ater being a value in the domain of X.

The second point of the article is just ease of notation. The derivative of a function doesn't exist; a derivative is always made with respect to a variable (df/dx), but if a function has only one variable, then the derivative of the function is defined as the derivative of the function with respect to the one and only variable and we don't need to write this only variable (f'(x)).

You could always write the variables of a function (df(x, y, z)\dy instead of df/dy), but that's just a waste of time, specially when you have to write it for every line of the demonstration.
These are just issues that someone unfamiliar with a field would face. None of them are problems for those of us in the field.

First, the expectation thing. He's using a special case, E(X), and complaining that the more general case doesn't follow the general case. It's like saying "Well the plural of mouse is mice but the plural of house isn't hice!". The general definition of expectation (for a discrete probability) is

E(f(x)) = sum f(x_i)* p(x_i)

If you start with this general definition, both E(X) and E(X^2) are perfectly natural. The author's error of starting with the special case in no way implies an issue with notation.

And how is the fact that Wikipedia is inconsistent between E(X) and E[X] in any way mathematical notation's fault? If you read a novel that starts using ' for quotes and switches to ", that's an issue with the novel (assuming its not stylistic) and not an issue with the typography in general.
Do you find the replayability of smallworld is largely due to the randomisation of which (race, attribute) pairs are available per game?

Arguably Dominion has good replayability for similar reasons: you only play with a subset of the cards every game, and a lot of the strategy revolves around exploiting interactions between different cards. On the other hand Dominion is one of those games where there is very limited interaction between players, which perhaps doesn't make for great replayability.
"DISHONEST, DECEITFUL AND CORRUPT"
the problems I had were mostly with good names. So names that are 1. already used in everyday life AND 2. really fit the concept.

These words have definitions in my head that I use often and now math uses them differently.

Like 'Menge' (german for Set) which has 'almost' the same definition in math and everyday use.

I like the physics approach more, gluons, quarks, protons, etc. these are all words that never had any definition in my life in the first place
I remember being so outraged when i was first introduced to derivative in high school... Seeing that they didn't use the same notation nor exact same definition in my physics class and maths class, in the same year, that was making me absolutely furious...
Leibniz notation is very interesting as it is not technically correct but it is still is used in lots of maths today.
