Comment Re:Exactly what was feared in ICANN handoff (Score 1) 141

You are partly correct and partly wrong. IANA is part of ICANN, so it is not independent of ICANN. But the RIR's are independent organizations. For IPV4 IANA is out of the business of assigning address blocks, since they handed off their last blocks of IPV4 addresses to the RIR's. IANA is still involved in IPV6 address assignment, i.e. they are the top level of the pyramid, and they give out large blocks of addresses to the RIR's. But it would be difficult for IANA to try to enforce a policy like this, since they could only try to exert influence on an RIR, and each RIR services many countries. In this case, it is AFRINIC (the RIR for Africa) that is talking about adopting this policy.

Comment BBC Documentary: Space Race (Score 2) 78

The BBC produced a documentary called "Space Race" in 2005 that covered both the US and USSR space programs. Sergei Korolev and Werner Von Braun were main characters in the documentary. Many people in the US didn't like it because they felt it was overcritical of Werner Von Braun. Since I was already aware of the controversy regarding Werner Von Braun's nazi past, it wasn't surprising to me, and I thought it was reasonably balanced in its approach. Note that the subject is fairly controversial, so opinions span the spectrum from he should have been sentenced to life imprisonment for war crimes, to he was completely innocent. I believe that he did get a pass on a thorough investigation of his involvement due to his value to the U.S., and it is not clear from the details (biographies and documentaries tend to spin the facts differently) what the true story is. Anyway, if you want to learn more about Korolev you can search for "BBC space race" on youtube. The entire four part series is still available for viewing, and I thought it was well done.

Comment Re:What about the primaries? (Score 4, Interesting) 1430

Agree 100% that it is utter madness. I'm a Republican and I'm aghast that the party chose Trump. Both parties chose terrible candidates, and the ones running in the primaries weren't all that great either.

However, I don't agree that there is something that can (or should) be done from outside the parties to reform them. I have to believe that sooner or later something will give. The problem is that more and more people are leaving both parties, with independent voters reaching the highest percentages ever. What that results in is the remaining members getting more and more radical, with the parties finding less and less common ground. And it doesn't appear that things will get better as the Democrats look to get more radical after the results of this election. It's going to be harder and harder for a candidate to appeal to the remaining party members to get nominated, and then appeal to the more moderate independents.

Each party needs to come back to recognizing that they need to also appeal to the independent voters. Instead the independent voters get left with a choice of two terrible candidates. It's hard to imagine the two party system breaking down, but I feel we are on that path. If the current parties keep getting more extreme I feel that there will eventually be a movement for a new more moderate party (I doubt that any of the existing third parties will fill that void). In my opinion, perhaps the "Rational Party" would be a good name. :)

Comment Re:Duration Tracking (Score 2) 145

Agreed. There is no information available to tell how long someone spent browsing a page. Sure, if there is a record of a page retrieved, and then a record of another page retrieved that was linked on the initial page, and the time between those two retrievals was relatively short you can probably infer that the time on the first page was probably the time spent looking at the page. But in general people have a variety of browsing methods, may have taken a break to do something else (or their web browsing is the "break" while do some other task), etc. Any long time between page retrievals does not allow a conclusion that the time between those two retrievals indicates that the entire time was spent on that page.

Comment Re:security best practice? (Score 5, Informative) 924

How about doing anything that takes a long time and you don't want to remain logged in for it to complete? For example you are running a standard program that is going to take hours or even days to process some data, so you redirect stdin to /dev/null, stdout to one file, stderr to either the same file or another file, and you start the whole thing with the nohup shell command.

There is already a well established mechanism for cleaning up background processes, i.e. the SIGHUP signal. And there is already a mechanism for explicitly stating that you don't want a process to die when you log out, and that is the shell's "nohup" command (which blocks the hangup signal that is sent to the process when the user exits).

And in what way does this new mechanism "enhance security"? Running something in the background after you log out doesn't give you any more privileges than if you remained logged in.

Why do the systemd folks think they need to keep reinventing the wheel? This feels like a solution in search of a problem.

Comment Re:The remaining 1/3 will turn off the lights. (Score 3, Informative) 147

Huh? Full disclosure, I'm an HPE employee. Where did you get the idea that HPE doesn't have any hardware products? We spun of HP Incorporated which does the more consumer oriented products that most consumers associated with HP, so that is why they got the original logo. They make printers, laptops, notebooks, desktops and workstations, and a lot more. Basically now we spun off the former EDS that HP bought from Ross Perot some time ago. We're still a major player in hardware. Just go to the HPE website ( and click on Products. We make servers, from smaller rack servers up to huge Enterprise scale servers. We make storage hardware, network hardware, etc. Basically, if it's something you'd find in a corporate data center, we make it AND support it.

Comment Re:Pressure suits and air supply (Score 4, Interesting) 100

This is already partially solved in a way similar to passenger jets, which have to deal with a similar problem. You need enough oxygen for each passenger to last long enough until the problem can be addressed. For a passenger jet, that means 12-15 minutes while the pilot dives to low altitude. For a low pressure tunnel emergency that means slowing the train down and then letting normal air pressure into the tunnel in a controlled fashion. As far as air resistance is concerned, I think you are thinking about lower speeds than are planned for a hyperloop solution. Hyperloop designs are considering speeds that approach or possibly exceed mach 1. Drag goes up exponentially (velocity squared), so the air density becomes a much greater issue at those speeds. Besides drag, you also have to take into account the heating of the train due to drag.

Comment Re: Maglev,,,, really? (Score 4, Interesting) 100

Maglev is becoming a viable technology for long distance rail. The low pressure tunnel allows for more efficient low drag travel, perhaps even supersonic travel. How do you propose that the train "float" on a cushion of air in a low pressure environment? What form of propulsion are you proposing that is going to work in this low pressure environment, assuming you have a solution for the "floating" problem that doesn't involve maglev?

Comment I think "Head Transplant" is the better name (Score 1) 256

Yes, I agree that "Body Transplant" technically makes more sense, however, as other people have noted, the head is part of the body. When you hear "Head Transplant" you know exactly what it means. If you hear "Body Transplant" it's not completely clear what that might mean without further clarification.

Comment Re:Obligatory reading (Score 2) 419

Right, but the other side of the equation is not zero. Coal fired power plants, and the associated mining is responsible for the vast majority of mercury in our food chain. During normal operation, the effective radiation released from coal fired plants are ~100 times that of a nuclear plant. Combustion of fossil fuels produces air pollutants that lead to increased cancer risks and statistical increases in related deaths. Combustion of fossil fuels also are a major source of greenhouse gases.

Then note that the Fukushima accident was close to a worse case scenario, i.e. a major earthquake, followed by a tsunami. Even then, better planning could have prevented this disaster. The safety standards in place at Chernobyl were so ridiculous it's not even worth considering when it comes to accessing nuclear power risks. Lets learn from our mistakes and make improvements, rather than throwing in the towel and increasing use of fossil fuel power plants.

I applaud the view of France, who never wavered in their pursuit of nuclear energy, as opposed to Japan and Germany who overreacted to the situation. I think both countries will eventually regret the path they've taken. I'd certainly like to see the U.S. pursue nuclear energy, since it is the only practical clean energy source that addresses the issue of base load, other than hydroelectric plants, which have significant limitations in where they can be installed.

I'm all for other clean energy sources like wind and solar, but anyone who thinks we can move to them for all our energy needs is living in a fantasy world. The only way that can happen is with unrealistic breakthroughs in storage technology, not the steady increase in storage capability that we've seen over the last 100 years. Stop reading and believing all the "major breakthrough" stories posted to Slashdot regarding this. Inevitably they turn out to be false, or just another step on the same progression we've seen over the years.

Comment Re:Won't save most of the 4000 lives (Score 1) 615

But perhaps some of those accidents caused by the car drivers are indirectly caused by the truck drivers. Truck drivers used to be the knights of the road. Now they drive like they drive their car. A lot of times when there is a backup of traffic on a highway it is due to a truck trying to pass another truck. They start to pass, get to a hill can't complete the pass, start to pass on the downhill, then hit another hill, etc. Sometimes it takes more than 5 minutes for a truck to get ahead of another truck and then they proceed to travel a 1-2 mph faster than the truck they passed. Meanwhile, as soon as the pass is complete, a lot of car drivers speed up to pass the trucks before another truck gets the idea that they have to pass another truck. Or they try to pass on the right of the truck that is still trying to overtake the "slow" truck in the right lane. I've seen lots of crazy maneuvers made by car drivers in this situation, induced by the incessant need for truck drivers to pass other trucks, which didn't seem to happen anywhere near as often 20-30 years ago as it does now. So yes, the car drivers may be ultimately respsonsible, but some of it is brought on by the behavior of truck drivers. With AI trucks we'll probably see a lot more truck caravans all following each other at the same speed in the far right lane, without the need to keep passing each other.
