Comment Re:I hope he wins in court (Score 1) 992 992

Hmm... let's re-word that a bit and see how you feel from the other side:

Flying a drone in a populated area is unsafe in nearly every circumstance. Just because there's no malfunction doesn't mean there couldn't be. If the done had suddenly dropped altitude, would the pilot have tracked it like a skilled operator to land it? Would that have brought the craft down to a point where the pilot could have endangered neighbors? What if the drone landed in the pool? Was the pilot certain that in all cases his flight-range was clear before flying? These are all things which a responsible drone owner thinks about.

I hope the pilot gets a big-ass fine (I'd hate to pay for his jail food out of taxes). I also hope the flier gets a fine for trespassing - or even just gets called into court and let of with a warning. The lawyers fees will probably be 10x what the drone cost to begin with.

Also, that would be willful interference.

  Section 97.101(d) of the Commission's Rules prohibits amateur operators from willfully or maliciously interfering with or causing interference to any radio communication or signal. 47 C.F.R. 97.101(d).

But hey, I think you can argue the situation calls for it anyway!

Comment Only for developers: replace numbers with symbols (Score 1) 519 519

Try this one out: remap the upper numeric keys from numbers to the symbols they have above the numbers. When you need a number, hit shift to get the numbers or use the numeric keypad.

I find it very annoying to hold down shift so often while coding. I almost never use the upper-row numbers as numbers, but I hit a lot of symbols coding in C and C++. I definitely use the symbols more, why do I have to hit shift to get to them?

Just look at a hunk of your favorite OSS project's code. Are there more numbers or symbols?

Granted, any facebook/gmail computer user wouldn't get this at all...

Come to think of it though, if you are working in uint space (that is, unsigned ints), than you *can't* have approached from below zero.

And if you were for some reason working with unsigned ints that were always multiplied by -1 than I think you'd still be ok with -1 * inf as your result.

Just so we're clear: this is stupidity -- the algorithm is not returning useful data and it will only mess up everything down the line. Sanitize before you divide, handle divide by zero as an error or a special case.

if(x1!=x2)
{
slope = (y2-y1) / (x2-x1);
}

If x1 == x2, you probably don't actually *need* a slope. You can mark those shapes or lines as perfectly vertical. Any algorithms that process based on slope would just skip those lines. A simple bool array that accepted pixel or shape (not really sure of the application) coordinates could return several useful parameters that would keep other algorithms from tripping up.

You might think this is a lot of overhead, but passing uint(-1) to an algorithm needlessly, or rotating your entire scene to avoid this is also a lot of overhead. If you just make a single pass over the scene and store the parameters (remember, memory is plentiful these days compared with CPU), then you can do very simple logic on the processing side, re-using the stored results.

You can fix the math by fixing the algorithm, no need to return results when the results are not only undefined but also not useful.

I have been suffering browsing the web with only one audio channel per ear for literally decades.

What to them so long, this is embarrassing. When I go to the movies I get to smell expensive popcorn and experience 6 to 16 channels of high-def audio. Why not on my windows smart phone and my tablet?

You might be right that this is a loaded Trojan horse.

However, I have no problem with what is on the surface. These are good ideas -- the internet is very much deserving "public utility" status. I'm not worried about fast lanes, I'm worried about intentionally making competition-owned services slower. The internet is a freaking power outlet, it should not matter what brand of hair dryer I plug in. If I need more power, I buy more power (bandwidth). But it doesn't matter what I am using it for.

The thing is we're worried about what comcast "might" do. And you're worried about what the NSA/government "might" do. Well maybe we're both right, did that ever occur to you? Maybe the government wants to overreach, to spy on your ebay shopping and snoop on your email. Maybe private industry wants insert extra ads while I web surf, or slow down Skype so that I am more likely to use iMessage, or make Amazon faster than Netflix in return for a little cash on the side. or whatever. Lots of maybe here.

We have to attack on both fronts. Neither party is trustworthy here.

I'd say they are as qualified as the democrats. The democrats are convinced and will vote for anything related to it. The republicans are convinced the other way. Neither party is being particularly scientific about this or any other political issues. And yes, this is only politics. Climate science deserves a lot more than a binary vote.

There are no significant differences in the senators between the two parties. They both wine and dine together, both came from big old-school money, went to Harvard, etc. Mostly law degrees. What did you think, the democrats were all scientists and the republicans all oil surveyors?

Grow up, take the blindfold off. You have been pulled into drinking the party's punch. Stop before it's too late.

Comment This is Funny (Score 1) 667 667

This is funny, the implication is that politicians know a lot about climate science. Ha!

Climate science is so much more complex than "warming" or "not warming". Anyone that wants to boil it down to only one variable really isn't trying to solve or understand anything.

What would be great is if MRO could try and make contact on its next fly-by. That antenna would certainly work under a solar panel, it would just have considerably less range. But knowing where it is now, we should be able to jam a signal down the front end and make contact.

If the solar chargers are still functioning with 2/3rds of the design power...

Comment FreeBSD (Score 1) 403 403

Without a doubt, FreeBSD is the best at these tasks. I have used it in the past and you can create a basic forwarding firewall with only a few lines of config. Add a dozen or so more for better control. I also ran BIND, isc-dhcpd, and a wifi access point. This would be a little tough under OpenBSD and NetBSD as they don't have quite the same range of wifi hardware supported out of the box.

FreeBSD has good package management and is very well documented. In many benchmarks, it is faster and scales better than the other BSDs. SAMBA will work fine, as will netatalk and NFS.

Having said all this, running your own firewall is a really good skill and enjoyable hobby. But if it ever becomes more of a burden than an enjoyable task, switch to a high-performance router running linux (no routers with linux have stooped to systemd yet that I know of). I have an ASUS that can seriously handle all the throughput that I can throw at it. And now I have more time for other things!

PS: If you're not already aware, in addition to local caching, BIND can also connect to DHCPD and create real DNS resolution for your local clients.

In case of injury notify your superior immediately. He'll kiss it and make it better.
