Comment: compression, spread spectrum (Score 1) 197

The more a signal is compressed, the more it looks like random noise. The only way you know the difference between a signal and random noise is redundancies. But redundancies represent an opportunity to save power and bandwidth, by adding compression.

The typical alien civilization has had hundreds of thousands of years to work out compression algorithms.

On top of this, spread spectrum might be used.

So what makes anyone think that SETI or anyone else would be capable of recognizing an alien signal if they saw one?

The fact that people are trying to draw conclusions from this failure, is a sign only of colossal human arrogance.

The GPL restricts the "Extend" step so that Discontinue step is impossible.

Any derived work of something, like git, which is GPLed, must be GPLed. That means that if you fork, the main branch, the main branch is free to use your extensions. This makes it difficult for replacement to work.

Furthermore, if you try discontinue step, others are free to fork and continue. So discontinue does not work.

The GPL completely breaks the "Embrace. Step 2: Extend. Step 3: Replace. Step 4: Discontinue." process. Which is why it is hated.

Hagfish Slime Could Make Super-Strong Clothes 82

Posted by samzenpus

Having the ability to create a 20 liter cloud of slime and tie themselves in knots, hagfish have always been one of my favorite deep-sea denizens. Being a living slime dispenser has not won the species many fans however, with the notable exceptions of Mike Rowe and Dr. Egon Spengler. All that is about to change thanks to the work of a research team at Canada’s University of Guelph. They've found that hagfish slime might be used to make new plastics and even super-strong fabrics. From the article: "A research team at Canada’s University of Guelph managed to harvest the slime from the fish, dissolve it in liquid, and then reassemble its structure by spinning it like silk. It’s an important first step in being able to process the hagfish slime into a useable material, according to Atsuko Negishi, a research assistant and lead author on the paper in this week’s journal Biomacromolecules. 'We’re trying to understand how they make these threads and how we can learn from that to make protein-based fibers that have excellent mechanical properties,' Negishi said. 'The first step is can we harvest the threads. It turns out that is doable.'"

A real test for science will be when someone discover some result as disturbing as this one, the result gets independently confirmed, and then it just sits there unexplained, for 10 or 20 years.

This result may not be an example, yet, because it has not been independently confirmed yet. (Who knows if it will be?)

Something like this is bound to happen sometime. (Some think it already has.)

Will physicists have the courage and humility to admit current theories are broken, or will they act like geologists with respect to Wegener, before nuclear fission was discovered?

What is scientifically known is infinitesimal speck in a sea of truth.

What is currently known is a very small faction of that which could be scientifically known.

Science is a restrictive methodology i.e. the scientific method.

Human beings have ways of knowing things that are not scientific. So the class of things that could be known, is even larger, than the class of things that could be scientifically known.

And then there are the questions human could pose, for which there is no conceivable way for humans to confirm an answer.

This is the unknowable. "Our line is too short to fathom such immense abysses."

Then there are those truths for which humans can not even formulate the question.

Strictly speaking all programming is math. Digital computers are symbolic manipulators. We would be alot better off if the Federal Circuit Court understood this.

Wheather you need continous math such as Calculus depends on if you are programming in a area that uses continous math. Like mathematics, statistics and many others. All programmers use discreate mathemantics, if they know it or not.

Saturn, Pluto, and Jupiter are all conjunct during that year, all while square to Uranus.

Perhaps the author has read Cosmos and Psyche by Richard Tarnas but does not want to reveal the real source of his theory.

But I predict that nobody will consider that. Everyone knows that Astology is incompatable with the mechanist materialist paradigm, and is therefore bunk.

Nobody will consider astrology.

Good software is not designed by the central committee; The central committee screws up everything.

Good software evolves.

You need to forget all grandiose plans to fix the software, especially if the ideas come from academia. Become unprincipled with respect to practicality.

The software has already evolved a lot. If you attempt to recreate from scratch, you will almost certainly repeat previous errors, even if you avoid the current maintenance mess.

The problem is that the software has evolved towards external goodness, while ignoring maintainability goodness.

Make a secret plan to slowly evolve the software towards maintainability.

Slowly sneak maintainability and sound software practice in the back door when no one is looking.

Scream loudly about how big the mess is and how amazing it is that anyone can make any changes at all to it.

Make the point that it is not how well the elephant dances, but the fact that the elephant can be made to dance at all. This will give you more time.

There is no way to prove whether a nation is engaged in offensive cyber warfare. It will always be possible to say those things were done by criminals and malefactors. "The secretary will disavow all knowledge of your actions." If those leaks had happened in China, the leakers would be shot and their families billed for the bullets. Therefore, if a treaty is signed, it will be a one-way treaty partially enforceable in the West only.

It would be colossally foolish to sign such a treaty.

I can not imagine such a treaty being ratified.

Therefore, baton down the hatches a storm is coming.

Governments and other criminal organizations can place esentially unlimited coersion on any organization or individual that publishes encryption or other security software. If the source code is not published there is no way to know that there is no back door.

Therefore the only way such software can be known to be secure is if the source is published.

Use free software for security.
