While it would appear that the protestors were misguided in this instance (though perhaps they weren't, I only know what the article tells me), the near-fetishisation of Japanese culture in the West does bother me.

Japan's status in the West does seem to be different to that of other Asian nations, probably because it's a 'developed' country. But then, isn't that only because in the Meiji era, it rapidly 'Westernised' itself to appeal more to Western tastes and be taken seriously?
Nice approach! "reload" was a nice touch to learn.

What I miss usually are two parts of deploys that are often ignored, and are critical in production environments:

1. Revert/rollback to older versions. We're humans and despite having all the processes sometimes murphy's law applies on moderate to complex server setups.

2. There is git/svn for code tracking, but even more important is the database consistency. Versioned backups and restores should be also part of the whole setup.

I'm currently looking into having the full setup with no downtime with open ears.
That SQL statement that does update and insert is pretty cool. It chains together both parts into single statement so it doesn't even need to start and commit trasaction, right?

It makes me wish for some kind of "advanced postgres" guide.

A new photon is emitted after absorption by the old one, the new one is absolutely indistinguishable from the original. The few that remain absorbed will slightly warm up the glass which then regains thermal equilibrium by throwing off a photon at a much longer wavelength in a random direction.

Why would you keep your FB posts public and not limited to your friends or to some subset of those (depending on what you are posting)?

Comments here seem to once again indicate as if everything posted to Facebook was automatically and irrevocably public. I don't really see that going on at least on my group of friends.
Interesting.

I think the point about the mathematics being too difficult for a "rank and file" programmer is probably a little off base. It isn't so much that the concepts are difficult as the fact that it seems prohibitively time consuming for relatively little gain that would put most people (especially those managing a project) off using formal specification / verification to build their software.

In most cases besides safety critical systems, it is acceptable to ship a product in 1/10th of the time, knowing that there is chance that there are imperfections.

Additionally, having used the Z language mentioned in the article, and taken some classes in university on formal methods, the thing which put me off the most was the (necessary) verbosity of the specification languages that are used for these type of things. I never wrote something that wasn't incredibly trivial, because it would have taken too long.
Waveishly.
I'm not sure Martial is as risky a bet as people make out, it's not like United don't have a similar analytics team in place (every premier league team does), doing the same kind of analysis.

Arsene certainly revolutionised scouting, but I think now it's a lot more well understood by other managers.
Indeed.

If ALL we're interested in is what others /think/ of us, then by all means let's hedge our bets in that regard. If looking stupid however is a byproduct of a longer journey to achieving something, then who cares what others think about our intelligence or our paraded stupidity.

But if looking stupid affects our chances of achieving what we set out to achieve, then we should be more circumspect before acting.
> the new one is absolutely indistinguishable from the original

This is where I get stuck, because no one explains this. How do we know this is true? Is this because they match in all the parameters that we're aware of (say, momentum, spin, whatever), or is this because it has been proven (through a Bell-like test) that there cannot be any other parameters that we are potentially unaware of, and hence if they match in the known ones, then they are one and the same?
I'm not coldtea but the implication appears to be that they are being bribed
> The main problem with them is that Delorean Motor Company didn't really follow the concept of "model years," instead changing things as they went along, so restoring one to original condition is practically impossible.

I've heard there is a new car company that does something similar (not having precise model years) and also offers a car with gullwing doors.... I think it starts with a "T".... I wonder if they'll be hard to restore when collectors look back in 20 years.

In my opinion, this is one of the major unsolved (or under-solved) issues in web development. You have to write and test migrations, and then you have to make sure the migrations are tied to your deployment/rollback process.

If there's a service/tool that automates a lot of this or makes it safer, I'd be really happy to learn about it!
I don't know how to explain it. It's fucking annoying. While programming, I have to remain focused and mentally aware. While talking to anyone at work, I have to act like a ditzzy vally girl or hippy of some type. If I don't do this, I'm pegged as a threat. I've found that I can really only get shit done in a remote office, otherwise I'm circle jerking the whole staff. In short, some of us Americans hate it too.
to be honest, to most cultures out here/there general average American is by far the loudest person around, beyond any modesty. Usually not really appreciated, and the more traditional (ie didn't change that much in last 500 years) the culture is, the worse the effect.

Personally I like it, a very different approach to self-presentation, that in some situations is more effective than usual shy polite careful... whatever,.

But if you go backpacking in remote places somewhere in south asia for example, it can cause a bit of friction with locals sometimes.

Everybody is little bit racist. It's about how much you act on it.

It's awfully like with Christian morals. Everybody is a sinner. Everybody pretends to be Zealous. And everybody mocks everybody else for being sinners. Donate money/buy indulgence, what's the difference? Just remember to be ashamed of yourself.

I'm not sure if this is Christian cultural undertones finding a new way to surface. Or did church just capture something very integral of human psyche with their rhetoric. Hopefully this bullshit is eradicated if the idea of "thought crime" becomes unpopular enough.
The fact is that all these options are more complex than just using Nim.

Cython is certainly great, but still Python objects and C structs differ, and you have to keep in mind the difference. Same for C functions and Python functions. And if you use the dynamic features of Python, you do not gain much in efficiency, because Cython does not have static dispatch, hence it has to rely on runtime checks.

In a way, Cython is its own language, and it is not a particularly powerful one. The help you get from types is limited, as many things will just have type object. At this point, I just prefer to use Nim, which is friendly enough, and has overloading, generics, macros and many other features.

I’m Not an Elitist, I’m Just an Alpha Female
It's interesting, reading about how my counterpart at other shops do it.

In our own Django web app, we basically just use the load balancer for deploys. Our service provider (Linode) has a nice API, so when deploying we just do one server at a time and direct traffic away from the ones doing the upgrade. It's not complicated and works just fine... At least when there are just two machines.
I suppose that's a catchier summary than "Facebook history may allow people without credit scores to get loans".

After a moribund launch of my well-intentioned startup in 2012, I know understand what others meant by "you have a lot of courage" (to leave your job and take the risks). What they mostly meant really is that I had the courage to look stupid. Except I didn't know that or care much for what "bravery" meant.
To expand on that a little with a software analogy, is it a bargain because they hired a talented intern who graduated into a full-time employee, or is it a bargain because they hired someone talented from a different country who has lower salary expectations?

I think PostgreSQL still executes it as a transaction, even though it is a single statement.

While benchmarking this, I learned that with the default and safe settings (synchronous commit), PostgreSQL can only do few hundred write transactions per second, however simple. Set synchronous_commit=off in postgresql.conf and TPS goes into thousands.

I have a question that's slightly off-topic from what OP asked. Is it possible to know which particles are entangled? If I have a pile of particles, can I say that a select group of them were still entangled while others are not?

In his book Hyperculturality (2005), the Korean-German philosopher Byung-Chul Han distinguishes between "cultural appropriation" and "cultural exploitation." He argues that appropriation per se is not a problem (because culture, after all, is generally not diminished by being appropriated), but exploitation is. Exploitation occurs when there is a clear power differential between appropriator and expropriated (think whites poking fun at blacks in a society that used to be based on the slave labor of black people), but there are plenty of examples where processes of appropriation do in fact lead to "new creativity" (think Korean tacos).
Well, very unlikely you will pay some 30+ aged footballers (except GK) much higher value regardless of which countries they were from. But for youngsters, they are full of potential, so a tool to help the club to scout is very helpful. In the past, they are relying heavily on "scouting agents", and that's bit of an art than science with data backed.
I would suggest that the cartographer’s sensibil-
ity is becoming ever more crucial to public life. We are awash
in data, and all our “look-up” needs can be fulfilled in a matter
of seconds. But we also rely on maps when making sense of
the world — we use them to orient ourselves historically, socially,
and politically as well as geographically. This has always been
the case, but what is new today is the opportunity for unusual,
provocative, or minority points of view to reach a wide audience.
Pick an issue — anything from drone strikes abroad to the
Olympic bid in Boston — and imagine a map that reframes
the debate. Now go make that map. For the cartophile, loving
maps should mean producing them, too.

I think he doesn't really value the point that more people have access to geo (and other open) data and to excellent mapping/visualizing tools nowadays.

Could they do that? You'd probably have to read (and keep up with) the T&Cs.
Most of the time the domain name will be sent in the clear anyway. For example, when you connect to a plain HTTP site, the domain name will probably be included in the "Host" field. When connecting to a HTTPS site, it will probably be included in the Server Name Indication extension field during TLS handshake.

Of course there are many times the domain name will remain hidden, if the DNS record is encrypted, but that is not a fraction of total use cases, and I doubt there will be great force pushing for DNS encryption.

In football (soccer), more so than in sports like baseball in America, players' costs are often more in the price tag when getting the player than their wages. A very good player might make £10m/yr in wages, and cost £50m to buy from a different team.

Unknown players will be cheaper on both, but even if you picked them up on a one year contract and they immediately proved that their next contract should be highly paid, you've still saved a potentially huge amount on buying them before they were worth a huge signing fee.

Gradually salary will catch up based on how well they play and based on the market, and the team that found this cheap player can either stop considering him a cheap player (but still be glad he came in cheaply), or can sell him on for a profit.

The top 10 salaries in the premier league range from ~£10m/year to ~£15m/year, so consider that buying a top player and keeping them for 2 years can often cost £20m-£80m. If you can buy a player for cheap and pay him not a huge amount, you can afford to spend a few years turning him into a star player and still come out way ahead even if in those few years he wasn't giving you value other than turning into a better player.

How long does it take for a player to become legendary? "Legendary" would normally be reserved either for the very best of the best, or on a team level based on both quality but also loyalty - as such you'd rarely see someone be called a legend before spending quite a few years at a club. But a player can go from relatively unknown to "shit he's really good" in as little as a season potentially - maybe he was playing in a league that doesn't get as much attention from countries with the bigger leagues, maybe he needed better team-mates around him to bring out his best, maybe a manager or coach helped him change his playing style very quickly, etc.
The whole NTP protocol (and deployment practices of the public NTP infrastructure and most private NTP deployments I've seen) is not terribly compatible with strong security -- a better implementation can only go so far.

Fundamentally the NTP implementations work with very strong assumptions that the servers they speak to are honest-- and even ignoring that the network authentication parts are so unusable, well-- that they make PGP/GPG look like a iProduct by comparison, this assumption just isn't a good one because it makes the security very brittle.

Look no further than the widespread false leapsecond events in the last couple years. If NTP gets bad data _by mistake_ can we really expect it to stand up to an actual attack?

You need root to install python packages globally. It's always a good idea to deploy without requiring root permissions, for example using sudo with only nginx/gunicorn reload commands allowed.

No, it doesn't mean that there is no magical hidden property that actually distinguishes them, but that as far as we can tell they're indistinguishable. Given that nothing about the photons is different they must be the same right?

Semi-unknown players from mid-tier clubs simply cost far less in transfer fees than established high-profile players. A classic Arsene Wenger signing was Freddie Ljungberg (https://en.wikipedia.org/wiki/Fredrik_Ljungberg). He was signed from a team called Halmstads in the Swedish league. While Halmstads were doing pretty well in the Swedish league at this time, they were unknowns on the world scene. Since Arsenal had little competition in signing him and since Ljungberg was pretty unknown they were able to pay £3m - which is not a large sum at that level level. For some context, at the time the most expensive signing in the world was Denilson who Real Betis bought for £20m. However Ljungberg went on to play 216 games for Arsenal, scoring 72 goals which is a considerable number. For comparison Denilson - who was played in roughly the same position - played 186 games for Betis and scored 13 goals. Ljungberg is generally considered to be an Arsenal legend, while Denilson is thought of as an embarrassing waste of money and gets barely a footnote on the Real Betis wikipedia page.

As for what is considered a "legend" I really don't know, football is weird like that. It could be that you achieve this status by being an aggressive no-bullshit kinda guy (Vinnie Jones at Wimbledon), a world class player who stays at the same club his entire life (Ryan Giggs @ Man Utd) or just being an insanely prolific striker who scores for fun .

On this topic though, various newspapers\magazines\sites periodically publish "worst transfers" lists which are basically filler (everyone who cares already knows who will be on the lists), but which could be surprisingly enlightening for someone who's not familiar with football's transfer scene. This one's a bit advert-y but you'll get the gist: http://bleacherreport.com/articles/1610214-13-stupidest-tran...
Depends on what you call enlightenment. In the zen/taoist sense, it actually results from _dropping_ your expectations, ie. just do your stuff.
No to both questions. Both would allow you to violate the speed of light if it was possible.

Once you measure a particle it is no longer entangled, so if you could tell if a particle was entangled or not then you can violate the speed of light by instantly knowing an action taken on the other particle.

Numba is a great technology, but I find it still a little disappointing.

The way I see it is this. Python is not a particularly fast language, but has evolved a big ecosystem of scientific libraries. Now people are running into the language limitations, hence the development of various tools to compile parts of Python - either AOT or JIT - with PyPy, Numba, Cython, Numexpr and so on.

The problem is that all these tools (save from PyPy, which is just a different interpreter) introduce their ow sublanguage, slightly incompatible from one another. For instance, both Numba and Cython have to infer types, but their type systems are not equal.

Nim does not have the reach of Python ecosystem, but it is a solid language, that manages to combine well the speed of C and the simplicity and flexibility of Python.

I would rather start from a solid foundation and add libraries on top of it gradually, rather than start from a developed ecosystem and add a host of tools that try to fix the inherent limitations of the platform.

Hence, in the short term it is great that the projects created by Continuum exist, but eventually I would like to have something a little more consistent
