Clock drives? Today's hobbyist telescope mounts have incredible precise stepper or servo motors, many with optical encoders so precise that they know exactly where they are pointing to. I don't think you can get a clock drive anym

I disagree with the astrophotography thing. Even with a telescope your human eyes are limited to planets and the moon, that's it. Forget about seeing galaxies with the naked eye, unless you have a 1-meter diameter telescope. All other

I'm talking about a healthy athlete, not one that it's into professional sports and actually destroys his body or hearth with substance abuse.

Healthy for the mind, sure. For you cardiovascular system? I doubt it.

I think it's pretty obvious. I believe that it is not that exercise helps, but sedentarism is poisonous. A sedentary 40 year old looks and feels 20 years older than a 40 year old athlete.

I did write a remote kernel exploit for OpenBSD, it was not an easy task, and this was in a time when there were basically no exploit countermeasures in kernel (2007) ( https://www.coresecurity.com/content/open-bsd-advis

True. Don't forget that the whole "Matrix" and "V for Vendetta" movies that came around the same time as Anonymous attacks. They got culturally embedded as hacker symbols.

What would be, for example, a passive attack against a CS-RNG?

128 bits is widely considered a "big enough number" that a exhaustive search even on the fastest computers today will require an unthinkable amount of resources (time and power). It's the threshold for "secure" algo

>Kernel CSPRNGs do need continually updated entropy pools. But not because their original entropy is depleted! Rather: you want your RNG to be updated so that its "key" changes regularly, so that if your system is compromised t

At long distance, inter-symbol interference caused by dispersion are the main causes of bit-errors. I saw a Clariphy whitepaper about a very good digital dispersion compensation engine, based on a custom implementation of the Viterbi algori

The only interesting sounds are the sync and line measuring tones. Actual data, I mean the QPSK or QAM modulation sounds like white noise to us.

Ironically, Venezuela has so much oil that gas is almost free. Most people dont even know the cost, they fill a car's tank with about 0.10 us$. Probably, people will start using the portable power generators that everybody already have

No. Argentina, Brazil and other latam countries really do not need donations. Venezuela is a very rich country that actually have the second largest oil reserves, ironically. It would be like donating stuff to Saudi Arabia. Our problem is r

The 10.3 u$s per month is possible. You have to remember that using the government exchange rate, food also is very cheap. Gas is almost free, IIRC about 5 or 6 bolivars to fill a tank (about 0.006 u$s I think). The thing is, you cannot buy

I believe they also have 2 or 3 "correction" fires of the engines in every trip. They know of their exact position by looking at the planets and radio waves. I remember reading somewhere that the Curiosity mars ship initial impuls
