Lasers basically push the potential engagement ranges MUCH further out.
That is obvious:D but one of the parents claimed you easy could hit stuff in a geo synch orbit, while I pointed out: that is more than 1/10th of a light second distance.
How much is a target going to maneuver in 1/10th of a second? To evade the laser the target would need to change velocity such that it wasn't anywhere near where it was going 1/10th of a second prior, and then continue to do that every 1/10th of a second as the laser continues to fire at it. That would be thousands of Gs of continuous acceleration unless the target was the size of a speck of dust, which would require incredible amounts of fuel unless the target was the mass of a speck of dust.
Now, hitting a target out by Mars is a different story - light travel delay is going to make that very hard unless you take a shotgun approach (blanket an entire region of space with enough laser fire to hit the target eventually no matter what it does).
I think most of their patents are around FAT32, and Google doesn't use that on any of their phones (no SD cards or USB storage mode, so compatibility-wise it isn't needed). I'm not sure what else MS is claiming these days.
Not yet. What I'm surprised at is that ChromeOS doesn't either, which makes it about the only OS still using Upstart. Their upstream, Gentoo, does support systemd but not upstart.
3 links at the bottom of the page going over regulation for government, non-government, and hobby usage, including relevent references to existing law.
And none of those laws pertain to drones. At most they give the FAA authority to regulate them. That means the FAA can create regulations. It doesn't mean that they can put up a webpage and tell people what to do.
By all means cite a law or regulation you believe says otherwise. However, I want a citation of a specific passage of law, not an FAA website.
I work in IT and I've never gone a year without a raise, for a single employer.
The thing is, it isn't a startup, and it isn't a software company either.
Whether you call it a raise or not is another matter, but if companies NEVER increase base salary they're basically asking their employees to leave. That's the only avenue left open to getting a raise.
Looks like the FAA already has regulation in place for what you can and can not do with drones. Popping over to their site, while they do not have huge amounts of it, they do seem to have some pretty clear rules already in place.
As far as I'm aware, the FAA does not have a single regulation in place for what you can and can not do with drones.
They have lots of webpages full of things they claim are rules, however they are not regulations.
I'd certainly be interested in anything to the contrary. I'm sure you can find a citation in the Federal Register, where all legally-binding regulations are published.
The FAA has only taken one company to court over this stuff, and the court actually ruled against them for this reason.
So what's the current situtation? Is it unregulated, or is commercial drone flying blanket banned?
The FAA would say that commercial drone flying is blanket banned.
The only court ruling to date on the matter says otherwise, but I believe it is being appealed.
The issue is that the FAA didn't go through the rulemaking processes with any of this stuff. They're not actually allowed to just issue press releases and call them regulations.
Well, sending the data to the aircraft owner is probably the simplest solution. Regulators can demand that data from them when it is needed. That is basically how all the other logging/monitoring/etc works. If you land a plane in the USA the FAA can ask to look at your maintenance records. If you don't fly in the US, then the FAA won't bother you, though some other country likely will.
I agree that politics still plays a part. A big issue is pilot privacy concerns. They're basically stuck in the cockpit 12 hours at a stretch and they want to be able to chat during downtime about whatever and not have the boss playing it back. I think that is a legitimate concern - we definitely don't want them trying to circumvent the recording equipment or trying to avoid being in the cockpit.
Perhaps give legal protection to the voice data, maybe even having it escrowed, but record EVERYTHING. In the event of a crash the private conversations of the pilots are of secondary concern to the public interest. In the event of a normal flight, then those concerns should be respected to keep out the nosy. The thing is that we have cameras all over the place in society and spooks recording all our phone calls as it stands - at some point we have to just manage it and not try to avoid it.
ACPId called a shell script in/etc, which I could edit.
So, just run a similar process today. Or, get whoever provided the acpid solution to provide a comparable systemd one. Normally end users aren't expected to tweak this kind of stuff.
I doubt it will ever replace large-scale manufacture. If you printed 300 whistles vs injection molding them or however they make them today, I suspect the printer will still have a higher marginal cost.
I do think it is unfair to lump in the entire cost of the printer. That is a bit like charging a kid $20k for a ride to school because you had to buy a car to make the trip. I'd look at how many whistle-like items you can make using a printer before it wears out and figure out the per-whistle cost that way, plus the cost of consumables and waste.
Recording data on black boxes requires a whole bunch of standards/etc. All it takes is somebody saying "do it!"
And I'm fine with having one bitrate of telemetry going out over satellite (including position, of course), and a higher bitrate of data being captured in a black box. Plus, if the satellite link goes down the black box is still useful.
Sounds like the average slashdot discussion, actually.:)...cough...systemd..., and your post is a criticism which got modded up. Deserved or not, I think people like to pile onto criticism.
Liberals are just as happy to sensor speech that they do not like because it is pro-Christian/American or anti-Muslim/Mexican/foreign sounding.
FTFY
Sure, but nobody lumped together liberals and libertarians, which was what the post was complaining about. All three groups are fairly distinct, with some overlapping areas of agreement.
What you call self-censorship I would call being civil. A society establishes rules and norms for behaviors it considers acceptable, and individuals are still free to act contrary to those norms; however such actions are subject to the condemnation of society at large.
I tend to agree in general, and I'd be the last person to make a racist comment/etc. However, one thing that does disturb me is that with the advent of social media and such a passing comment can get turned into a national movement.
If somebody makes a racist comment to somebody, they SHOULD be called out for it. If it was unintentional, then they SHOULD apologize and say so.
My problem is that you get things like somebody posting something offensive in twitter and it turns into global campaigns to get somebody blacklisted from any kind of professional job for the rest of their life. That isn't the right solution to the problem either, and I think it tends to result in the kinds of anonymous outlash you see here, though much of it is just idiots being idiots.
I wish I had a better solution to offer though - I don't think that this kind of behavior is at all acceptable. I just think that as with many offenses the punishments we hand out only make things worse.
I like the idea of the 3D printer mainly because I have 2 small kids and a dog, so toys are broken or chewed quite often. Being able to print new parts and figures overnight as a treat is a nice idea. My problem is the $4k price tag on one plus the plastics and other work once printed. I like it being popular because more and more things are being made for the hobby, but I'd like the demand to come down, and the price for the basics to get started.
Sure, but for a common item like this the cost is going to be 99% in the materials, and I imagine that those are going to be cheaper for some chinese manufacturer than your printer.
It would be like trying to print a paperback book on your home printer. Sure, you can sort-of do it, but it will cost you a LOT more than the 50 cents per copy or whatever a publishing house can do it for, since they aren't using a general-purpose printer for the job but rather machinery optimized for the efficient production of books.
And yet counterfeit parts are still a big problem in Asia-Africa airlines and maintenance facilities...
All the fancy computer systems in the world won't make a difference when there is money to be saved by working around them and somebody with the ethics to make it happen.
It's 2015 and we use GPS to find our way back to our car in a fucking parking lot and let we lost an airliner because it seemingly can't be outfitted with the same tech...
If you think they're bad, you should talk to the neckbeards flying single engine planes. You'd think that the ECU in your 1975 Chevy was invented by the devil himself: http://macsblog.com/2014/08/pi...
I don't get why we even need to find black boxes and such. How much bandwidth would it really take to just stream that data in realtime over satellite, and how much would that cost compared to the tons of fuel in the tanks?
The topic is Google chrome (which is the Google branded version of chromium). I am running it now. I downloaded it from Google. Look at this page. It clearly claims suitability for Debian/Ubuntu/Fedora/openSUSE and other OSs.
If the first update will break it, they have no business offering it without a big fat warning.
I'm not sure why Debian cares about Chrome one way or the other. It isn't FOSS.
You might suggest that Google changes the webpage - presumably it was written back when it was true. Better yet, tell your friends to not install software outside of the package manager unless they know what they're doing. Since you obviously know what you're doing, I'm sure you'll figure it out.:)
I know that calling mayday properly takes work. However, keying the transmitter and shouting your callsign and the word does not.
A proper mayday call is to be preferred over just yelling mayday into the radio. However, if for whatever reason you don't have time for that (maybe because you're busy trying to aviate/navigate), making an improper distress call is preferable to just silently wrestling with the plane until you crash. Just yelling mayday will at least get people looking for you, etc.
And before you claim that systemd is easier to understand, please make the ACPI sleep key send my laptop to sleep under systemd. So far many people have told me how systemd is "simpler" but no one has been able to help me fix this really simple problem. It worked just fine under the old system.
Debian is hardly the only distro that doesn't yet have a new enough kernel. If their target is chromiumos, then they shouldn't represent it as suitable elsewhere.
Where do they represent it as being suitable elsewhere? I don't believe they distribute binaries of chromium, and the linux build instructions don't really list explicit dependencies.
In any case, Debian can backport the feature, or just stick with an older release of chromium and backport security fixes to it (which is basically what they do with everything else anyway, though chromium moves a lot faster than most project so I can see why they wouldn't want to do this).
If your goal was to train hundreds of Jihadis in the art of hijacking modern jet-liners, then there is no real substitute for having the real thing in your possession - even if it is forever grounded in an underground bunker. You cannot just go and buy a 777-200 without leaving a trail. Plus a fair deposit......
I still wonder if the plane was stolen. No 'terrorist announcement' motive needed.
The fact that nothing has been identified is too mysterious. No oxygen masks, foam, rubber, sandals-nothing, 300 tonnes makes a big debris field, which expands exponentially over the weeks and months. All it takes is a single identifiable object found by a fisherman, beachcomber, surfer, coast guard, shipping or dog, in what is now a 12 month period.
Maybe it didn't 'go down' at all.
Where would it go? If they flew anywhere near a coast they'd be picked up by military radar. There are a lot of conflicts in that area - Afghanistan, India/Pakistan, anywhere in the Middle East, piracy in the Indian Ocean. Unless they had specialized gear the aircraft would not be able to detect and avoid military radar.
He added that "the first thing you're going to do" as a pilot during an emergency is "don the oxygen mask" and "confess to ATC [air traffic control], 'We've got an issue, we need to return.'"
This is quite a surprising statement. In an emergency, the pilot priorities are:
1 - Aviate -- Maintain control of the aircraft
Broadcasting isn't first priority, though donning an O2 mask in the event of unbreathable atmosphere would be right at the top of the list. There have been crashes in the past when this was not done, and any competent crew should be donning masks if there is any reason to think the air might not be breathable, which would include smelling smoke or a pressurization alarm.
Broadcasting an SOS is a very high priority, even if you haven't gained complete control of the aircraft, even if all you have a chance to do is shout mayday or whatever. Even if by some miracle you do manage to not die on impact, you want somebody to be looking for you immediately, especially over water. Calling mayday just requires keying the mic and shouting the word.
The circumstances of MH370's disappearance were anything but normal from a procedures standpoint.
