Comment Re: Will Internet Voting Endanger The Secret Ballo (Score 1) 219

Laymen cannot audit this system, nor is the process of assuring anonymity and an accurate count transparent or comprehensible to laymen. That means they cannot trust this system... which is kind of an important aspect of a ballot.

In California I make inkspots on a piece of paper, then it is fed into a big machine. I get s sticker that says, "I voted!" Is that better?

Really? Noone can figure out who you voted for and you can ensure your vote was counted properly? I thought it was one or the other. Care to point me in the right direction?

Most of the voting systems by David Chaum. I assume others' systems as well. All of these systems work by similar methods. One common trick is that if N numbers are XOR'ed together, then any number can only be revealed by again XOR'ing with the other N-1. So your vote can be XOR'ed with something that hides the actual vote, but the combination of the two can be checked from a list. There are other methods as well. I would explain it all, but I am not a cryptographer.

There are provably secure cyptographic methods to ensure that no one can figure out who you voted for, and that you can check, after the election, that your vote was counted appropriately. These systems even include a method for providing a faked screenshot to be sold to vote buyers. The fact that almost no one uses these systems is the real problem.

If it has to be something you can remember, then some examples are substitution cyphers (eg, rot13, but more complex substitutions work better), keyboard patterns, interleaving two words, spelling backwards, mixing two languages, &c. For example, a substitution cypher of the keyboard key up and to the left moves Password to ")qww294e". Tough choice for mobile, though. Interleave: mybank -> "m!y@b#a$n%k^". Now go make up your own.

I spent a year or so working on fire detection for the Orion project, which was, at the time, sending folks to the moon. Fire in space is an incredibly arcane subject, with almost nothing known. On Earth, convection is everything, but in space, there is no gravity to drive convection. In other words, hot air doesn't rise. So flames do really weird, unexpected, unintuitive things.

Our Hidden Neanderthal DNA May Increase Risk of Allergies, Depression ( 134

sciencehabit writes: Depressed? Your inner Neanderthal may be to blame. Modern humans met and mated with these archaic people in Europe or Asia about 50,000 years ago, and researchers have long suspected that genes picked up in these trysts might be shaping health and well-being today. Now, a study in the current issue of Science details their impact. It uses a powerful new method for scanning the electronic health records of 28,000 Americans to show that some Neanderthal gene variants today can raise the risk of depression, skin lesions, blood clots, and other disorders.

Qualcomm Promises Gigabit LTE Speeds and New Chips to Power Smartwatches ( 46

Qualcomm may have been losing steam (and jobs and sales), but it looks like the major telecommunications corporation is back in the lead when it comes to pushing out new LTE technologies. Qualcomm announced today the new Snapdragon X16 modem, which together with the WTR5975 transceiver, boasts Category 16 LTE download speeds of up to 1Gbps. Qualcomm also announced new chips that will power the next generation of wearables. Although you shouldn't hold your breath just yet, the implications could be huge!

That's... amazing. Color me incredibly jealous.

I'd guess they were throwing away nearly all that aperture -- to get all the scope's light through a 4mm exit pupil, you'd need close to 2000x magnification, which would make the nebula look like it was about 24 degrees across -- okay, that would fit perfectly into a normal field of view.

So, yeah. I hate you even more.

(Wonder what kind of 4mm lens could successfully catch all the light from a system that size? It's been a long, long time since I was immersed in the amateur-telescope-maker literature...)

The exit pupil of the eyepiece is probably more like 20 mm, so that the observers don't have to get their eye exactly in the right place. Wastes a lot of light. I was there last time they put an eye piece on Magellan. I remember being able to spot four moons by moving my eye around, but I no longer remember if it was Jupiter or Saturn.
