Back 20 years ago when I was doing my undergrad, optical amplifiers [0] were a thing. In theory it's possible to boost signal without repeating. Is it the case that they're still too expensive or are we talking old legacy long haul infrastructure that hasn't been updated yet?

I'd say it's more likely to be some sort of routing or even filtering overhead between the two national jurisdictions. Plausibly there be some kind of layer 3 filtering going on ...

As someone who _does_ know about Minecraft I will say you're probably right on the Network Effect in particular and go into this a bit more:

Modded Minecraft is pretty unlike a typical modding community. Few people add one mod to their Minecraft game, what people tend to do is run a mod _pack_ which is typically dozens of mods with different authors that are integrated together by the pack author the way a movie's Editor turns hundreds of hours of pictures and sounds into a coherent 2 hour film.

It's out of hand enough that you will see people saying e.g. "Ugh, I can't face Magic Bees without Gendustry" - Minecraft doesn't have any bees at all, bees are added by a mod called "Forestry", then magical bees are added to that with "Magic Bees" by a different author and the mod called "Gendustry" by yet another author exists _solely_ to make the genetics gameplay from the Forestry mod more... industrial.

So there's an _ecosystem_ at work here, akin to the Windows vs Unix ecosystems and that network effect applies to your whole ecosystem.

The PC "Java" Minecraft associated with modding actually ships new versions relatively often still after all these years. But because mods are so involved, even tiny changes under the hood can mean hours of software development for the mod authors, so the ecosystem moves to newer versions less steadily, a "pack" of mods will usually be forever associated with a specific Minecraft version. Unlike most games which "upgrade" like a web browser or operating system, Minecraft actually lets you pick at start time which version you want to run in order to facilitate this. For example one of the most famous packs "Agrarian Skies" is for 1.6.4 and will never work with a newer Minecraft but still has some players.

As a result of players being interested in this ecosystem rather than the individual mods, it only takes one of dozens of key developers to stymie a move to a different platform, whether that's a new Minecraft version or somebody else's Minecraft clone. If this happens, the only way forward is for part of the ecosystem to evolve around the gap which happens much more slowly.

Example: A big part of Minecraft is crafting, and mods often add dozens of new things to craft and even new ways to craft things. Rather than have a web browser open on your phone to check what you're doing as you play, the game needs an integrated way to remind you how to make, say, a Wireless Crafting Terminal (yes that's a thing you can make inside the game). The first mod to do this was called Too Many Items. So a pack would add "Too Many Items" and that made players lives easier

But TMI was limiting and ceased to be maintained. What to do? Fortunately Not Enough Items came along. Not Enough Items was maintained for a long time, and became pretty sophisticated, able to tell players which complicated industrial machines could produce which products and with what inputs. But eventually Not Enough Items too fell by the wayside and in the latest Minecraft versions packs use Just Enough Items which is different but arguably better.

I don't even see why you'd need them to work in other parts of the brain. Directly manipulating mood and emotion would already give you an enormous power about a person.

As psychology research shows (skinner etc, the current discussion about manipulation in games) - controlling emotional rewards would also have a big influence on the "rational" decision making of that person.

I think the "let's publish the good-natured stuff" is more about the target values they seem to tune this system for. Sure, you could tune it to counteract mood disorders and steer the subject towards emotional stability. You could also tune it to other targets.

I highly doubt that the king massacring half of the current power structure for his own ends, and castrating the other half is an arab spring, and will not bring increased freedom.

We all know what's coming next: a few incidents where the old power structure takes some small measure of revenge, followed by mistrust, fear and repression. The king, and all of the new government, does not trust it's hold on power and will have to cut benefits across the population. These things don't mix well.

Half the western press is implying that the current king, who was not even the successor to the throne as little as 5 years ago is really an attempt to modernize and westernize saudi arabia. This is exactly the line the saudi government is putting out (while keeping significant parts of the old power structure hostage at gunpoint one might add [1], maybe worse than just keeping them hostage [2]). Currently the king is taking a populist viewpoint, but that's out of desperation and fear.

The economic reality means he's going to have to cut financial benefits to the population by a lot. And if there's one thing for absolute certain in this world, it's that that has never brought social progress. Conservatives will increase in power as a result of this for obvious reasons. What will happen ?

It's embarassing, one might even suspect a lot of money is involved in that western press attitude.

I like the question, hadn't thought about it before and now I want to know. The article doesn't give me much answers though. Mostly seems to clarify the question.
A simple question for you. Do you think the way up the current US political ladder is more about merit or more about quid quo pro? I think there's this sort of cognitive dissonance many of us are suffering. Are you happy with your professional politicians in Washington? Do you think they're doing a good job? It seems to me that many people want change in Washington, and don't appreciate that the 'political experience' rhetoric is being pushed by DC insiders in an effort to try to strengthen their own grasp on power. 'Outsiders' pose a far greater risk to establishment politics in DC than ever before thanks almost entirely to the internet.

It's a similar story with education. Education in the US is deteriorating rapidly. And so why exactly would you want to rely on people who are experts in this system? We tend to ignore that a system is little more than the individuals that make it up. The reason US education is failing is because the individuals who we currently consider have assigned 'expert' status to, clearly do not know what they're doing.

Experience is something that should be valued, but not all experience is created equally. I have a rather worse than negative view of Zuckerberg, but I would vote for him before almost any establishment politician. Einstein referred to insanity as doing the same thing over and over again, and expecting a different result. And by that account, I think we have a national epidemic of insanity.

Imagine you're explaining what you were doing to a programmer pairing with you, or to a junior dev, or just someone who is smart but lacks context.

When I started coding, as a teenager, I'd pace around the room explaining things to myself almost as if I was giving a lecture, so it's fairly baked into my thinking process. If you assert something, laying a statement out there, the process of hearing it can cause you to start to think other things: is it actually well-justified, are the assumptions behind it solid; what are the consequences and implications of the statement; all the things you might think if you heard someone else say something, and you're listening critically and intently.

I have no information either way on the subject, but generally, no, it not exactly a novelty that a government announces a grand intention, and mostly even sticks to the letter, but drifts significantly from the spirit when applying the intentions under the constraints of everyday political life. Not because of any specific malice, but because governments are huge beasts the sit on top of a huge intricate web of opaque incentives.

> Aren't high contention and deadlocking workloads essentially the same thing to a deadlock-detection db?

High contention means that there are many concurrent transactions modifying the same rows. Deadlocking means transactions modify the same rows in opposite orders. The former definitely does not imply the latter. Most workloads are simple enough to never have any deadlocks.

> which is exactly what (many) avoidance systems do for you in the first place.

This might work for very simple database models which require the user to specify all the keys that are going to be modified in the transaction upfront (NoSQL). In PostgreSQL, a transaction can contain any number of statements in any order, results are returned at the end of each statement - before the next statement is known, and modifications can have complex, non-deterministic WHERE clauses.

The database has no way of knowing which rows will be affected by an UPDATE and DELETE in advance, and therefore it does not which row locks it needs to take in advance. Even if it first read and sort all the data, it still doesn't know what the next statement is going to be. The only way in which the database could avoid deadlocks is by taking very aggressive predicate locks on the table, which is obviously bad for concurrency. Another possibility is to use wound-wait, but this introduces retry delays when there is contention even when there are no deadlocks. Moreover, because results (e.g. number of rows modified) are returned after each statement, a transaction cannot restart from the beginning (since it might modify different rows the second time), so in practice wound-wait would have to unnecessarily abort transactions if you were using it to avoid deadlocks between multi-statement transactions.

It is generally much, much, much more efficient to just let UPDATEs run without predicate locks or retry delays. They will only get into an occasional deadlock if the user has transaction blocks that make changes in a different order. In those cases you can have deadlock detection save the day, and tell the user how to avoid running into it again.

> What's the advantage of putting this burden on the user?

If a transaction has multiple statements that modify the same rows in different order then the two choices are: reduce concurrency, or, detect deadlocks as they occur. The former is a severe pain that all transactions have to pay, the latter is an occasional, preventable pain that only deadlocking transactions pay. Clearly, the former would be the higher burden.

Does the light signal in an fibre optic cable get noisy over distance? If so, then wouldn't an analog signal amp such as this simply amplify the noise along with the signal? Decoding and re-encoding would have the effect of 'cleaning' the signal in this case. If it does get noisy, where does the noise come from? The medium? Leakage from outside the cable?
Reader mode in Safari (at least on iOS) renders this nicely for me automagically, and turns the grey to a nice black.
