Report: Big Issues Remain Before Drones Can Safely Access National Airspace

damm0 Re:For safe integration with existing air traffic (129 comments)

Any pilot will tell you that birds are responsible for avoiding bird strikes 99.999% of the time.

If drones move out of the way of airplanes autonomously, then great. They don't though. Hobby drones aren't really the issue here anyway, the real issue is the larger drones.

Also, some guy goes out and buys a drone, takes it up for a flight. Does he even know that he's within 4 miles of an airport? A lot of people have no idea where the GA airports are. Some really fundamental training on air space rules would go a long way towards safety I think. A few hours of ground school at the most, and passing a very simple exam. Could even be an online thing.

Report: Big Issues Remain Before Drones Can Safely Access National Airspace

damm0 Re:For safe integration with existing air traffic (129 comments)

Helicopters frequently fly at 300 ft. And I think a drone is more of a hazard to a helicopter than an airplane.

Also, I bet there are a lot of people who have no idea where airplanes might need to be flying low. One strange wind day, one aircraft with unusually low performance like a Cessna 150 or an old Cub, and one strange airport situation like a Class-D upwind extension and presto, you have airplanes at 300 feet where they normally are not.

Report: Big Issues Remain Before Drones Can Safely Access National Airspace

damm0 Re:For safe integration with existing air traffic (129 comments)

Historic precedent with airplanes would show this is not the case.

Companies incentivized to fly as often as they can have sacrificed airplane maintenance and pilot capability so that they can increase their profit. There are reasons that there are substantial limitations that commercial companies who want to fly for profit must meet.

With drones you'll see this as carring payloads barely within its capability envelope, drones flown hazardously above crowds, drones carrying hazardous materials, pilots without any understanding of human-carrying aviation airspace, etc. I could add a dozen more reasons why being paid makes things more dangerous.

Last Forking Warning For Bitcoin

This is the part I don't understand- why does the block chain size need to enlarge? The system could just go on with block chains no larger than 1MB, could it not?

Ask Slashdot: Would You Accept 'Bitcoin-Ware' Apps?

damm0 Re:Sorry, no. (232 comments)

I think there's a great deal to be said for helping people in your community first. The results are more available to you, and recourse in the event of (e.g.) embezzlement of charity dollars is also more available.

Ask Slashdot: Would You Accept 'Bitcoin-Ware' Apps?

damm0 Re:Why play games? (232 comments)

I try very hard to memorize my numbers, but since my running average in between credit card theft activity appears to be about 1 year, that's a lot of effort for nothing.

Seriously; I do not give out my credit card number to sketchy sites and try to avoid scams, yet it gets stolen anyway. For example, I am a Linode customer and they announced that they were hacked the day after I gave them my new credit card that had been updated as a result of a motel booking scam in which my credit card was stolen. Replacing my credit card twice in less than one month? Ugh.

Open Source Radeon Gallium3D OpenCL Stack Adds Bitcoin Mining

damm0 Re:Wasteful (140 comments)

Processing new blocks will still be profitable because of the built-in "transaction fee" mechanism. Miners in the year 2100 may simply refuse to include transactions that don't have a fee of 0.000001 BTC, for example. At which point, there will be so many of them, that itself could be profitable. The profit is then not the fact that you minted 1 BTC, but the fact that you collected all the fees in the transaction block.

Kepler Watches White Dwarf Warp Spacetime

damm0 Anticipation (58 comments)

Since the current Kepler has produced stunning science, I sure hope they put another one up when this one conks out thanks to losing the last of its gyroscopes. It's a shame that Kepler is facing a crash just as it is hitting stride.

Do Recreational Drugs Help Programmers?

damm0 Re:Contradictory ... (878 comments)

I find the experience similar to yours, but I perceive there to be a great deal more "boring" code. When you get right down to it, really only about 5% of code is interesting in any meaningful way. There's a risk that poor workmanship will sneak in, but then again if your tests aren't good enough it really doesn't matter if you're drunk, stoned, stupid, tired, or cocksure, the product will suck.

The problem to watch out for is to think an idea is good when stoned, then tricking yourself into thinking it is still good when sober.

Some Smart Meters Broadcast Readings in the Clear

damm0 Re:C'mon Kids (138 comments)

> The hassle of managing encryption far outweighs the risk posed by unencrypted transmission.

Now that is absolutely not the case. PKI scales, and these days with a SIM card in most phones it is almost free as long as you set it up right. That part is hard, but it's a basically constant cost which gets less expensive over time.

Some Smart Meters Broadcast Readings in the Clear

damm0 Not All Vendors Are Alike (138 comments)

There's the implicit statement that all smart meters are deployed the same way. Since this experiment shows that one smart meter vendor is producing sniffable traffic. It does not show that all vendors are in the same situation.

Some vendors are better than others in this regard.

Contiki 2.6: IPv6 For Everything, Everywhere

damm0 Re:Darn, no mesh (62 comments)

I see it as a social engagement in Internet connectivity. Today, we depend on rather large infrastructure companies to provide cellular signal. From a social perspective this is not idea:
  * Near monopoly telecoms set the prices.
  * Infrastructure needs to be deployed everywhere (resulting in near monopolies.)
  * Radio transmissions require a lot of power to get to the local tower (or else suffer poor performance.)
  * Privacy concerns; data must flow through the provider's infrastructure, and the provider must know your general location.

A publicly supported mesh would have to include micropayments in order to incentivize people to put up infrastructure of their own, and would put the network into the hands of the people. Application software remains lucrative, as does hardware. Route negotiations include automated financial negotiations. This is what I'm getting to. And rather that simply trusting our providers to be nice (a rather naive prospect), it becomes intuitively obvious that the network itself is insecure, and that security rests in the identity of the user and their associates.

The result can in fact be highly robust and performant, without centralized nodes that control routing. Devices of all shapes and sizes can join and engage in the mesh, from radio controlled LED christmas lights to basement server farms. There's a kind of routing called Landmark routing which I personally believe is promising. It basically follows the greatest routing algorithm we know; the postal system.

Contiki 2.6: IPv6 For Everything, Everywhere

damm0 Great! Now just solve the routing problem! (62 comments)

Sure, a decent enough platform I guess.

Now, to solve the routing problem! I want to send an email to one of my Contiki buddies down the street. How does the name get resolved and how does a resolved IPv6 address get turned into a route? How about a few miles away? To my buddies in Australia?

And how do we firm critical mass in the mesh, or provide a network effect to get everyone on board?

Finally, let's not forget about the electromagnetic sensitivity problem.

But these are all solvable. Let's go!

We'll let established security protocols solve the application layer problem.

apt-build and cryptoloop

damm0 damm0 writes  |  more than 9 years ago Two new tools discovered:

First, apt-build. Admit it, the idea of compiling packages optimized for your CPU is appealing. With Debian, it is easy:

[Welcome to "apt-build world"].

Second, cryptoloop. I moved my home directory over to a crypt'ed filesystem using [cryptoloop].

Fight Complexity (please)

damm0 damm0 writes  |  more than 9 years ago

Complexity is something my industry deals with. We write software for machines that execute billions of operations per second, so complexity comes with the territory. We've got so much power to burn, there's an entire industry based on a machine simulator (the JVM).

Many attempts have been launched to deal with the problem by abstracting problems to libraries, and in some cases it helps. Then along comes some coder who needs to whip up some protocol handler and goes crazy integrating every damned library they can get their grubby hands on. JMX. Servlets. EJBs. All for a silly little protocol handler that could just be wrapped up into some simple plain old java objects.

J2EE should be distributed with a license that reads "Warning: Contents might feed featureitis. Seek professional help now." Gah, I'm as guilty as anyone I suppose. I run a heavy desktop and I like it. I've been known to thrash myself into a tangled mess in response to new problems.

Maybe that's why the best is so expensive.

Call me a pirate

I went to A&B Sound to buy the Bony M Christmas album. We had a copy but lost it somewhere. According to the helpful staff at A&B, the publisher is not providing the album this year!

So I'm downloading it right now from an unnamed bittorrent source. Call me a pirate, but honestly, no Bony M?

Locked out of the Game

damm0 damm0 writes  |  more than 11 years ago Game 7 of the Canucks vs Wilds

Goal: Get real-time Canucks coverage. TV and Radio are not an option, so my remaining choices are find an Internet source or go to the local pub.

So I go the Internet route.

  • CBC: not an option, as they use Real Media. There is no Real Media player that will work on my Linux system.
  • CKNW (Vancouver radio station): Hosts their stream through a 3rd party... the 3rd party uses complex javascript that is not compatible with Mozilla, so I can't even find the URL to the stream
  • Canucks.com: Provides a link to "NHL Radio" but that ends up on a Microsoft site. The MS Site embeds the stream URL via an ActiveX control, so again, no dice. If I could only get the stream link, I could get mplayer to play it.

So frustration. I guess I'll wander over to the local pub, maybe I'll even enjoy it.
