1. China lacks a lot of knowledge when it comes to building and maintaining large things in space... 2. Imagine China could get this to work, there's so much lost in the down link due to the atmosphere you'd need a REALLY powerful microwave emitter or laser, at which point you've now got a death ray in orbit. There are pretty strict rules about NOT militarizing space and nobody would be cool with a country having their own personal death star in orbit. 3. If instead they decided to use low power, the collector on the ground would have to be so massive, it would have been cheaper to just invest that money into getting fusion to actually work.
Like all holy books, it's so vaguely worded you can twist to your means. In your sect of the great burger religion, your temples only allow people named Ralph. In my sect, they disallow Ralph.
Obviously, I'm going to have to start a holy burger war to resolve whose right.
I'm going to instruct my chain of burger joints to check ID's at the door... Anybody with a first name of "Ralph" will be turned away at the door. My holy book over here clearly states that "Ralph shall be name of the demon who will eat the world." I'm disinclined to have people named Ralph in my establishment who're likely to go into a demonic craze and start eating people. Also any "hussies" named "Roberta" or "Rebecca" they're just tricky sluts, they're not allowed in either.
MIT was showing this off awhile ago and I *believe* they sold it to DuPont... you can buy it in cans to coat things like boots. I think the innovation here is that they've made the coating either tougher so it won't abate over time and/or they've figured out how to make it food safe... I can't imagine making your insides hydrophobic would be that good for you...
The major issue with this is the time it takes to charge. My volt from completely depleted to completely full takes 3 hours to charge on 240v. To take a full charge or a 80% even the time has to get down to 15 minutes.
I'm an extremely happy Volt owner! It is by far the best car I've ever owned.
Question #1. What is Chevy's plans to extend the Voltec system into other models such as the Trax and/or the Equinox? I ask because my wife's current vehicle is an AWD SUV and I'd like to replace it with a like vehicle that's a EREV but is still AWD and has cargo room. I know the 2016 Volt has a square battery pack and thus a 5th seat, I can only assume that's to make it fit better in other chassis?
Question #2. Why does Chevy not promote the Volt?!? You never see a Chevy commercial that has the Volt in it. They had the "low battery" commercial a couple of years ago and then nothing. When I go places I have people constantly coming up and asking "A volt? What kind of car is this? Chevy? Wow, this thing's awesome! I had no idea..." My wife's joked I should become some sort of Chevy Volt Ambassador!
The paint flake incident is what lead the shuttle to be basically flow upside down and backwards at an angle to put as much ship as possible between the crew and and any debris.
I have heard talk of people pitching the idea of "space trash trucks" that would use a variety of techniques to capture and/or deorbit as much trash as possible. LEO is entirely too big to clean everything but there are some bands that are higher priority than others.
If a company bids and wins a chunk of spectrum they'd have X amount of time to do something with it, say 2 years. After that, if the company isn't using it, it would go back into the pool to bid on again. Possibly there could be some extension if the company could demonstrate that it was actively working (i.e. "Hey look at this 15 satellites we've got queued up to launch...") to use the spectrum.
It's rather ironic they named their bill the "Internet Freedom Act". I suspect the "Freedom" part doesn't apply to us but instead applies to the telecoms. Freedom from accountability, freedom from competitiveness, etc...
I clearly don't understand the audience that video is supposed to be for.
If it was scare the western world, it's only going to give the leaders better arguments for making a moral case against these barbaric sociopaths. If it was scare the muslim world... From what I've seen on reliable news sources, those countries that were on the fence or were somewhat ambivalent about ISIS are now in the "Let's obliterate those crazies before they attack us and/or we get lumped in with them!" camp If this was to somehow garner credit in the jihadist world and show that they're the most jihadist of the jihadists, I don't think that worked for them either. You have to admit, that even when Al Qaeda is calling you crazy, that says something. I'm sure they'll pull over the fringe players who don't think Al Qaeda is violent enough, but not enough to offset the massive casualties they're taking at the hands of US air power.
The only thing that I could see this as a ploy towards is to try to drive a wedge in and alienate moderate muslims from the western world. Something along the lines of "See the crazy thing we're doing, we'll we're muslim, and since you're neighbor is muslim you should think of them as being as crazy as we are!!!"
My only problem with that is that these people just don't seem that well planned. It seems like they're making it up as they go along and not doing a particularly good job of it. Killing the pilot, let alone in as grizzly manner as they did, got them nothing and only hurt them unilaterally. Holding on to him and trading him for prisoners would have demonstrated that they were people that could at least been negotiated with. Strategically this was a dumb move.
He could have simply made the book 260 pages instead of 240 and put in a 20 page chapter on ZFS right after RAID. The first couple of pages would be about the design philosophy of ZFS. Next introduce the concepts of vdevs, pools and pool types (in relation to what the reader just learned about RAID), sub file systems, snapshots and file system attributes. Next layout some scenarios using 8 disks in a JBOD. Create a raidZ, raidZ2 and a raid10. Next talk about tacking on another 8 disks and what the options would be for expanding a raidZ, raidZ2, raid10 set. Next talk about the pros and cons of read caches and ZIL's and ways to tune ZFS to be more performant. Lastly, talk about scrubbing and replacing failed devices.
I'll stand by my original argument... ZFS is essential to building scaleable networked storage devices with FreeBSD/Solaris and likely soon Linux. Yes, you could write the end all book on ZFS. Yes, someone like me would likely buy such a book. However, for your average sysadmin who knows nothing about ZFS this chapter plus google would give them a good starting foundation for building a storage device.
Naming a book "Storage Essentials" and then not talking about ZFS was a mistake. If you're going to be building any type of NAS, you're going to want to use ZFS for it's scalability, reliability and stability. While you might get away with UFS for a couple of terabytes, you're going to have a bad time of it when you've got 40TB worth of storage space to manage.
SpaceX has modeled the hell out of it. It's just really really hard. Honestly, I'd rather they fail in spectacular fashion and explore all the dark corners of their design before they stick people on the top of it. What's great about this is it's all gravy at this point. Once they work all the kinks out, it's going to eviscerate the competition when it comes to cost to orbit per ton. I can only imagine every other commercial launch company must look at SpaceX with a mix of horror and amazement.
Every magazine and newspaper in France should publish the offending cartoons on their front pages. Show these assholes that they wouldn't silenced with violence.
Agreed. I think the couple of days is due to orbital mechanics more than anything else. It could also be that because this resupply is so critical they're going to do some additional testing.
From what I know about SpaceX their testing regime is pretty insane already.
I've read both the offending article and the response from Krauss and frankly Krauss is right on the money. The article is so painfully full of woo and so devoid of fact I can only come to the conclusion that the editors at the WSJ are a bunch of biased religious pandering idiots. What's even more enjoyable is how the refused to print his rebuttal because in doing so it would have show how painfully shotty their editorial process is.
Dr. Krauss has done us a service by clearly demonstrating the WSJ is good for nothing more than lining the bottoms of bird cages where it can get treated with the respect it fully deserves.
Recreating my machine from install media isn't that gruesome either. However, I'd rather do it on my terms then have to suddenly deal with it. Murphy's law dictates it'll happen two days before a deadline or in the middle of something critical.
All the stuff I care about I make incremental offsite backups.
If you find yourself resorting to baking your motherboard in the oven to fix it, this is an act of desperation. Yeah the guy managed to get some more life out of the motherboard but this isn't a fix, this is a temporary hack.
We've now conflated two important distinctions into a single subject here. Functional resilience and long term data integrity. I solve the long term data integrity problem by doing nightly snapshot delta's of my whole machine and my wife's machine (to a rasp pi with an external drive at a buddies house). Granted that's a single point of failure, but it's out of house in case my house {burns down, get's robbed, etc}
However, that doesn't fix the near term issue of me busily working away on a project when boom, my drive fails and suddenly I'm sitting there looking at a paper weight. That sucks. Having that happen to me once was enough for me to say screw it, I'm buying two drives and mirroring them using the motherboard raid software (which md supports) and it's a non problem. This solves my functional resilience.
raid is not a backup, what is gives me is resilience. Would you rather spend tomorrow recreating your machine from install media and backups, or simply swapping the drive out and suffering a background sync?
I don't build a machine these days that doesn't have mirrored hard drives. You realistically can't backup 6TB worth of data, so barring some horrible FS failure (which is rare these days in Linux land) your best bet is RAID1.
For a falcon heavy having a fleet of these ships would allow them to recover all three first stage elements vastly reducing the cost to put really heavy things like all the elements for a mars transfer vehicle in space.

When you put the word "Cargo" in the title it's pretty self explanatory otherwise you're just a horrible person...

That's a no op for me since I've always avoided using switch/case statements anyway. I always saw switch statements as an omission of poor design...
Please describe a construct that you can do in C that you can't do in python?

Yeah, because in the 60's we were building reusable rockets that were autonomously landing on robotic ships in the ocean... oh wait.
