Comment Re:If you need math, learn it. If not... (Score 1) 601

Applying math skills to programming is all about problem solving. CRUD apps are a solved problem, and can (and should) be done with little or no programming required. In fact, there are entire development suites devoted to cranking out CRUD with as little programming as possible. There are legions of IT professionals that make their living that way.

But knowing how to use those kinds of tools to generate those kinds of apps is not knowing how to code.

There may be people who get significant success in real programming because they are good at decomposing tasks and classifying responsibilities, good at naming things, and good at getting to the heart of "what needs to be done".

Exactly my point. Those same skills can be applied to learning math, or for that matter auto mechanics. Your brother got the concepts of calculus once they were broken down (abstracted) into terms he was familiar with. He could have learned calculus, but he just never had an effective teacher.

Ok, so you can do a lot of coding without knowing math.

But being able to understand code and coding requires a lot of the same skills that are required to understand math. Ergo, if you can get good at math, there is a high likelihood that you can also get good at programming. And vice versa. You can do long division without knowing a lot of math, but that doesn't make you a mathematician.

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 Re:How I Found Linux (Score 4, Interesting) 136

I became a UNIX bigot in college in the late 80's. I remember following William and Lynn Jolitz's series "Porting UNIX to the 386" in Dr. Dobb's in the late 80's/early 90's. My first experiences with DOS PC's were disappointing, as I saw them as a big step backwards. My first download was something called Monkey Linux. A zip file that spanned 5 floppy disks, that when extracted to a DOS directory was bootable as a UMSDOS FS running a derivative of Slackware. I followed a pointer to the official Slackware package mirrors, and never went back.

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.
