Assume a really fast rocket is traveling from galaxy A to galaxy B. Due to relativistic length contraction, the distance between the galaxies is less as seen by the rocket than it is for a stationary observer in either galaxy. So the travel time from the perspective of the rocket (the "proper time" of the rocket) is less than the travel time measured by a stationary observer. And when you work out the math, the rocket's proper time approaches zero in the limit as the speed of the rocket approaches light speed.


What makes "mere hacking" different from true enlightenment?

Is it just the perspective of the one who has the experience? As Tim Leary said: The caterpillar cannot understand the butterfly.


One is rational and comprehensible, the other one isn't. At least that is how I read "spiritual" and "enlightenment"


Agreed. The fact that JavaScript lacks reasonable numeric types means that I never use it except when there is no alternative.


That's a strange comment considering that most people who get hurt in a blood-thirsty revolution are generally not the rich and powerful.


Depends on your perspective. There are worse things than death. And equalizing misery is almost romantic.

And compared to other revolutions, the French Revolution was not that bloody. It was just the localized executions that made for all the blood running in the streets for weeks.

Well, the revolts in the Vendée killed up to 130,000 people. But I doubt most of them were the rich.

But this was a counter-revolution, not a revolution.


No, while it was a revolts against the revolutionaey regime, it was not one to restore the pre-revolutionary regime or the classes who lost power in the revolution, it was a popular peasant uprising sgainst conscription by the revolutionary regime.

OTOH, even if it were a counter-revolution, why would it be excluded: would you really make the argument that a revolution isn't particularly bloody, if you have ignore the cost in lives of putting down attempts to restore the old order? That's part of the cost of achieved a revolution.


The counter-revolution was more to restore church power than the monarchy (that's how the peasants were enlisted, anyway), but that's not a relevant detail. Re why exclude: You were trying to prove that initial revolutions, contra the present upper classes kill mostly poor people. Might be true but can't be shown by citing counter-revolutions. Sure, similarly, White Russian soldiers killed a lot of poor peasants - but then, why wouldn't they?


> You were trying to prove that initial revolutions, contra the present upper classes kill mostly poor people.

Well, it wasn't me, and the claim didn't mention “initial”, it was: “most people who get hurt in a blood-thirsty revolution are generally not the rich and powerful.” I think it's fair to characterize people killed in resistance by the old order before the institutionalization of the revolution to be hurt in the revolution.


You are agreeing strenuously, I think.


It's not just the executions for the French Revolution. You have to add all the wars that followed during 20 years, including the wars fought by Napoleon. So we're talking a few hundred thousand deaths still.


"Most." Which implies a spectacular increase in the risk to the rich, who were previously exceptionally secure.


In absolute terms, sure, but that doesn't mean much since the rich and powerful are already a tiny (but powerful) minority.

Are you saying that in proportional terms the non-wealthy were hurt more as well?


I think scalable income is a more useful concept than passive income. What I mean by scalable income is when you can increase your income by investing more capital, but keeping time commitment and effort at the same level. In my view purely passive income is either some instance of rent-seeking, or simple risk-free return on economic growth. But even those require a minimal level of effort.


Servlet containers have two levels of isolation: individual apps are mostly firewalled from each other as you say, but when running multiple servlet containers they are as isolated from each other as multiple docker processes are when it comes to shared libraries, security policies etc. JVM processes are easy to reason about at the OS level, while servlet applications are more complex. But we are comparing Docker with JVM, not Docker with e.g. Tomcat webapps.


The JVM is a container by itself, and it has been able to isolate dependencies and memory requirements for many years before docker was conceived. The JVM doesn't do everything that docker does, for example it doesn't provide overlay file systems, but this is trivial to add via standard tools (e.g. aufs), and it also doesn't limit CPU usage per container but this is also trivial to add without having to deal with the extra complications of using docker. I think docker is great for non-JVM applications that run into conflicts with other applications, dependency-wise or resource-wise, but I don't see the point of using docker for pure Java applications. It just adds an unnecessary layer that provides no benefit.

Edit: If the point is to encapsulate and isolate a Java application as much as possible, I would consider using a unikernel like OSv before considering Docker. This would be more efficient and also more secure.


Animals have grunted at each other for hundreds of millions of years, and human speech has slowly evolved from this. Text however was an instant revolution, a complete game changer. I don't think text is going away.

The immediate benefits of text are that text allows information to be stored, verified, indexed, and searched (assuming it was indexed correctly). It's only very recently that these same benefits have become available for audio and video. But they are still way behind text. For example, it's a lot easier to quote a snippet of text than to cut and paste a scene from a video sequence.


How about a review of one that is marketed as anonymous or privacy-friendly? For example Monero or PIVX. Many people still incorrectly believe that Bitcoin transactions are anonymous (yes, I know they can be anonymous if you make an effort to make them anonymous, but by default they are not).


Korolev's contribution is even more impressive when you consider that he was imprisoned in the Soviet Gulag for many years (for political reasons), suffering under living conditions which probably shortened his life.

https://en.wikipedia.org/wiki/Sergei_Korolev


Seriously, I can't comprehend the guy.

He starts studying liquid fuel rockets in the '30s, and does some amazing work probably trailing only the top German engineers in this field.

He's denounced by some envious low-lifer who wanted his job and is arrested (along with Valentin Glushko, another great rocket scientist) during the stalinist Great Purge at the end of the '30s, when a simple anonymous note was enough to get someone disappeared. They torture him, sentence him to death - but then he's commuted to hard labor in the gold mine, where the poisonous environment and poor conditions meant the average life expectancy was barely over one year. Loses all his teeth to scurvy.

Meanwhile his friends back in Moscow are lobbying with Lavrenti Beria (the KGB boss) to release him - they succeed and he's placed in the "easy prison" where a bunch of intellectuals were doing essentially white collar slave labor (with pencil on paper, sure, but no choice in the nature of the work) for the Soviet government. He's released towards the end of WW2.

Then Stalin figures he needs to catch up to the Germans in rocketry, so Korolev is rehabilitated, made colonel of the Red Army, and finally starts working again on his rocket engines. They copy a bunch of German designs first, use some German engineers (who were prisoners) to get them started. Then continue on their own.

He develops the first Soviet ICBMs, but that was just what paid the bills. He keeps pushing for a real space program. Launches Sputnik 1 into space. Leads the Soviet space program until the mid-60s.

When he died, he was working on plans for manned missions to Mars and beyond.

I mean, what motivates a person to keep forging ahead against such adversity? Death sentence, hard labor in the poison mine, years of imprisonment and disgrace - and then he builds and launches the world's first ever satellite. To say nothing of the fact that, like Elon Musk, he was a man of many talents: great engineer, very effective leader, and a good politician and lobbyist. It's amazing.
