readerrrron Why Can't I Take an Orange Through Customs?

The last paragraph is especially creepy. You can be treated as an animal, whenever they please.

readerrrron Why Can't I Take an Orange Through Customs?

A simple web search shows that that isn't true.

readerrrron Why Can't I Take an Orange Through Customs?

So if you plan to take your laptop it is better to upload the disk image and buy a new one in the states? I'm assuming the TSA can force a foreigner to unlock and then copy the disk.

Wow this is sick:

readerrrron Half of stars lurk outside galaxies

I'm not talking about the time it takes, but the mass of the fuel. Which is more than just doubled.

That is what equations tell you: http://math.ucr.edu/home/baez/physics/Relativity/SR/rocket.h... ( scroll to How much fuel is needed? )

readerrrron Half of stars lurk outside galaxies

And the last paragraph is the main problem. The ship would get torn apart from lone atoms and to actually stop yourself you need an exponential amount of fuel, because you need to accelerate ( much more than )half of it just to stop yourself.

Even if you protect yourself from relativistic atoms, they still create a drag. And that happens before you reach 0.99c.

readerrrron Show HN: Axis - a React.js multiplayer math game

Just impose rules that are trivial for humans to solve reliably and not for computers.

Copy paste is disabled remember...

As for the rest, that is up to the developer with more resources than his opponents.

readerrrron Object Oriented ANSI C (1993) [pdf]

A full chapter is dedicated to dynamic type checking.

If that isn't acceptable for your project, don't use it. Successful languages that don't have compile time checks, show that this problem is irrelevant.

readerrrron Show HN: Axis - a React.js multiplayer math game

You can always make the game itself harder on top of all the anti-bot tricks.

The game has to be only hard and expensive enough to hack so that the effort isn't worth the result.

Of course with unlimited resources you can pretty much solve anything, if you assume those, then everything is easy to solve. But assuming that is simply ignorant.

readerrrron Show HN: Axis - a React.js multiplayer math game

There are simple ways to make that very hard. The first one is to remove copy paste.

readerrrron Show HN: Axis - a React.js multiplayer math game

It is crashing all the time, it should be back soon.

Even with all that I still keep coming back.

readerrrron Show HN: Axis - a React.js multiplayer math game

But it almost impossible to write a polynomial in under 60 seconds without any tools, that follows the desired path.

readerrrron Object Oriented ANSI C (1993) [pdf]

That is a very limited system without real polymorphism.

readerrrron Object Oriented ANSI C (1993) [pdf]

It has a very high learning curve. And while it has great ideas, the usage of variadic functions is not warranted in my opinion.

I recommend you first try a simple OO project yourself.

readerrrron Show HN: Axis - a React.js multiplayer math game

Agreed, functions should be continuous and no step functions.

readerrrron Show HN: Axis - a React.js multiplayer math game

Really great idea, too bad it freezes almost every game.

I think it just died...

readerrrron Milk Might Not Be Doing You Much Good

Sugar is the best and fastest source of energy found in the nature. We are programmed to like it and remember when we ingest it, and that behavior is rewarded by feeling good.

A lack of that feeling will make you feel less good. Experts say it takes up to a month for that imbalance to normalize.

Great talk about it: https://www.youtube.com/watch?v=aWLnlhLNa28&feature=youtu.be...

readerrrron Milk Might Not Be Doing You Much Good

You have to be careful even with fruits with high sugar amount. But it is harder since the digestion is slower and you get full faster.

readerrrron Milk Might Not Be Doing You Much Good

Every day with cereal for months now. I'm doing great, no problems whatsoever.

You should switch from sugary drinks to water and fruit. It takes about 3 weeks to adjust. ( and avoid chocolate milk )

readerrrron Source code of Polish electoral voting system?

I don't know, I wouldn't judge a decompiled code.

Can you give a few examples why is it so bad?

readerrrron Show HN: SineRider, a game inspired by my TI-86

Thank you! Game of the Year!

I wish I had this in school. This might just spark a new interest in pure math for me.

...

I think I broke it: y = x^2 / ( 6000/t^(t*t) )

readerrrron Is Faster-Than-Light Travel or Communication Possible? (1997)

After a year of acceleration at 1g, a stationary observer would observe a speed of 215184620 m/s or 71.7% the speed of light.

After two years: 89.9%

After four years: 97.2%

After eight years: 99.3%

readerrrron Is Faster-Than-Light Travel or Communication Possible? (1997)

Fun fact, from the perspective of the observer on the ship, time outside the ship would also appear to slow down.

readerrrron Is Faster-Than-Light Travel or Communication Possible? (1997)

lfuller is right.

For example, if you have a ship capable of continuous acceleration at 1g, you can reach any point in the universe on the order of ~50 years.

readerrrron Your Language Sucks

Manual memory management can get tiring. Only if you don't exercise.

String handling is manual memory management. See above. See above.

The support for concurrent programming is anemic. Introducing C11 and OpenMP!

Terribly named standard functions: isalnum, fprintf, fscanf, etc. Beauty is subjective.

The preprocessor is the best thing ever.

Not feeling your smartest today? Have a segfault. Can I have another?

Lack of good information when segfault occurs... the "standard" GNU toolchain doesn't tell you the causes of segfaults in the standard runtime. Enable debug mode.

If that code is legacy, you're in for two days of not looking like a hero. Luckily there are 137 alternatives.

:-)

It is easy if you have antigravity.

On a side note, I was surprised at his attempt at a romance novel. I was pretty good, but too long.

readerrrron ULA says “not yet” on reusable rockets

readerrrron Is Quantum Entanglement Real?

That does not work because light speed has a limit. It is true that the photon does not experience time. Imagine a photon traveling a distance of 1 light year towards us( we are stationary). In it's reference frame it will do so immediately but in our it takes 1 year. For the photon to travel to us in zero time in both frames, the speed of light would have to be infinite, which we know it isn't.

readerrrron Is Quantum Entanglement Real?

I wish you comment were downvoted instead of karmakaze's one.

He is expressing an opinion and even if he is wrong, it is still an interesting idea, and shows some effort. A decent short explanation could show the mistake, and make a good comment->answer combo.

Instead you quoted a comment which is out of context ( Feynman's comment is intended for physicists of his level ), contributing nothing.

( Please don't take this as a personal attack ( it isn't), but more a thought what's wrong with HN in light of recent debate )
