Comment Re:From TFA: bit-exact or not? (Score 1) 169

There used to be a web page called "Your Eyes Suck at Blue". You might find it on the Wayback machine.

You can tell the luminance of each individual channel more precisely than you can perceive differences in mixed color. This is due to the difference between rod and cone cells. Your perception of the color gamut is, sorry, imprecise. I'm sure that you really can't discriminate 256 bits of blue in the presence of other, varying, colors.

Rather than abuse every commenter who has not joined your specialty on Slashdot, please take the source and write about what you find.

Given that CPU and memory get less expensive over time, it is no surprise that algorithms work practically today that would not have when various standards groups started meeting. Ultimately, someone like you can state what the trade-offs are in clear English, and indeed whether they work at all, which is more productive than trading naah-naahs.

I don't have to apologize for national fiat currency, it's silly too, and I don't keep my assets in cash. My problem with Bitcoin is that it is even less credible than "the faith and credit of the United States government", which has been the justification of the Dollar since it was allowed to float. It seems to be nothing but "wish and it will come true".

Comment How I found Linux (Score 3, Interesting) 136

I was studying for my M.Eng in electronics and we were using Sun workstations for EDA software. After I graduated, I joined a startup company that produced chip layout software. We had purchased a bunch of Sun workstations, but they were going to take weeks to arrive.

So we loaded up a few PCs with Slackware Linux from about 40 floppy disks (took two of us an entire day to finish all the installations) and started our development on the PCs while we waited for the Suns to arrive.

No, the small-aircraft owners aren't at risk of messing up their avionics. They are, however, consciously messing up the cellular network for everyone else. You see, you are supposed to be in range of just a few cells when you use your phone, so that we get frequency reuse between cells. If you are at altitude, you are in line-of-sight communications with all of the cells out to the visible horizon on all sides. And the frequencies you are using are probably locked out from reuse over that entire vast area. It would not take very many phones at altitude to disrupt the entire system.

People who received a play-money system from a mysterious unknown person and actually convinced themselves that it has value are now facing a schism over the money market failing to grow without bounds. Unless, that is, the software is modified in a way that might, over time, disincent people from playing the game.

I can't be the only one who is thinking that the only problem is that these folks believe bitcoins have value.

Hell, I thought that the fiat currency of nations was a bad deal. This is an order of magnitude worse.

No, the real problem is that you have line-of-sight communications to every cell site until the visible horizon. This tends to use up frequencies over a very large area. In general the antennas have been engineered not to work at high angles, but this can't be complete and the ones on the horizon may see you at the same angle as their regular users.

Comment The problem is usually video (Score 1, Insightful) 378

Think of how we use video devices. Not just in Linux, in pretty much all current systems. In the name of "efficiency" we memory-map them, and we let the user process directly mess around with the internals of a hardware device.

This is the way a set-top video game box works, not a secure and reliable operating system.

Until the video is firewalled off from the user the way other components of the operating system are, it's not going to be safe, secure, or reliable. Obviously we'll need new hardware designs to make this work fast enough.
