There's also a lack of Rackspace-blaming here. The hacking was discovered in progress, and Zhou asked Rackspace to terminate all logged in sessions - which they couldn't do (!). Thus they suspended all instances, which still did not stop the hacker from being able to delete them.
That in itself is pretty amazing. In a bad way.
All consumer electronics become cheaper over time. Their value deflates. Your argument claims that no one would ever buy computers, since they could just wait and get more for their money tomorrow.
Deflation rewards those that buy what they need, now.
Inflation rewards those that buy what they don't need, now.
You are right. This article is awful, conveying no sense of the nature of the problem or its complexity, and giving no idea of the solution at all.
The only equations I'm aware of for a falling particle subject to air resistance take the form
m v' = -mg -a*v-b*v^2
which is a constant coefficient Riccati differential equation for the velocity v. I'm reasonably sure this would have an analytic solution.
Maybe complications arise in the 2D motion case, or perhaps the problem includes a particle which is also spinning. Maybe the drag terms take more complicated forms. I don't know. The article is pretty dreadful to be honest.
But the truth is, making guns in a new caliber and making ammunition to match is easy enough that some hobbyists do it in their garage.
Yup. And a lot of times, those self-packed loads fail. Gunpowder mixture is the wrong type, wasn't packed tight enough, moisture, grease, etc. I've seen these hobbyists you speak of; All of them have at least one story of how they ruined their gun because their custom ammo was shit. You do it amateur, you get amateur results. But hey, don't let me stop you from taking your custom-built guns and ammo into a combat situation...
There are, apparently (I Am Not A Military Expert), valid military reasons to make your guns and ammunition incompatible with the enemy's. America and the rest of NATO were the first to use 5mm-caliber small arms - the M16, FAMAS, L86, etc. are all chambered for a standard 5.56mm round, and I believe most even have compatible magazines.
The "valid military reason" is called "economy of scale". We don't want to blow their budget on ammo, and by happy coincidence, our allies don't either.
Iran is simply doing the same thing. Instead of using NATO-standard 7.62mm miniguns, 20mm autocannons, 40mm grenade launchers or 2.75" rockets, they'll use ones that are just slightly incompatible, but nearly identical in performance.
That would be stupid. Iran doesn't have much of a defense industry; they rely on importing arms. It makes no sense to outfit some of your military with Mark I whatchamagigies and some of them with the incompatible Mark II whatchamagigies. There are few things more damning than sitting next to three full ammo boxes, and not one round that'll fit the only gun you have.
One reason is economics - trying to stimulate their own arms industry,
Whiskey. Tango. Foxtrot. You don't have to reinvent the wheel to stimulate your industry: That's a purely American thing. In the rest of the world, you steal tech, duplicate it, and save yourself the R&D costs. See also: North Korea, China, India, Egypt, Iraq...
Another could be that they are more concerned about being invaded, rather than invading others. You are, after all, more likely to be the one capturing supplies, rather than having your supplies captured, when you are on the attack.
The traditional response to this is to decentralize your weapons depots, caches, and supply lines, and to be as covert as possible. Every ground war we've fought against similarily sized and equipped militaries has been massively asymetrical, and the enemy wears us down by hit and run tactics (which we invented), and urban guerilla warfare. They don't give two shits how much you capture, as long as they've got just enough left to keep costing us economically. They know if we invade, we're out a few more trillion dollars -- and our economy just can't handle that right now (it couldn't before!). Stop thinking like this is conventional warfare: It isn't. It hasn't been since the 70s.
History would seem to bear this view out - during the Cold War, neither side used intercompatible ammunition, and as it turns out, neither side much wanted to invade the other.
History remembers that it doesn't really matter what ammo you use, as long as you've got a fuckton of it. And by ammo, I mean nukes.
The most notable case of cross-compatible weaponry was in WW2, when the British designed the Sten gun to use the same ammunition as the German MP40. And guess what (spoiler alert)? Britain later invaded Germany!
Yeah, why would a country who's factories were burning, a third of its population dead or injured, and entire cities leveled want to put their limited resources towards making sure they could use whatever ammo was available. The mind boggles.
OK, that's probably a massive simplification of things (remember, IANAME), but still, look at things from Iran's view for a second.
I am looking at things from Iran's point of view. I think you should go work for them. The kind of advice you're spouting could set them back an extra decade, easy. Save us a lot of money so we wouldn't have to build IED-resistant personnel carriers, missile defense platforms, and more stealth tech to give us a greater force multiplier.
Don't get an HP!
I had HPs and they are junk. Try calling them for support, the support people are idiots.
Buying on American Express doubles the warranty. I had computers fail, and Amex reimbursed me for the cost of the machines without much difficulty.
, Iran's locally-grown Cobras will be armed with 'different types of home-made caliber guns, rockets and missiles,' according to Iran's semi-official Fars news agency. 'All the phases of designing and manufacturing of the chopper have been done inside the country and the helicopter enjoys some capabilities which make it preferable to Apache Choppers,' says Brigadier General Kioumars Heidari. Iranian officials stress that Iran's military and arms programs serve defensive purposes and should not be perceived as a threat to any other country,
So, basically, you're copying 40 year old tech from your enemies, but because you can't buy the bullets or missiles to shoot, you're going to arm them with whatever you can cobble together. It's like Junkyard Wars, only with dictators instead of teams. Yeah... I can see why they say we shouldn't perceive it as a threat... but it's not because they're dangerous or anything. They'll probably kill more of their pilots in training flights than we would with a bombing run or twenty.
You just don't get it. Mobile is going to hire Steve Ballmer to crush them. With a chair.
Only if they can get more developers, developers, developers, developers. And considering the next iteration of their operating system's programming tools is full of limitations, limitations, limitations, limitations, I'm guessing even a supertanker filled with Ballmers and chairs won't be enough to convince anyone to develop for CrippleOS(tm) (aka Windows 8). And as has been learned many times over by everyone but Microsoft; It doesn't matter how awesome your product is... if you don't have people developing applications for it, it dies on the launch pad.
I'm glad to see somebody mention ad server response times. That is by far the biggest factor in slow page loads for me. I don't hesitate to move on to the next site when a site is sitting there waiting for an ad server to deliver content.
I don't mind too much opening multiple tabs in order to let one load on my desktop, but it really sucks on my phone.
Just yesterday I installed Adblock (Or Adblock Plus, whichever it was) on Firefox for Android; hopefully it's as good as the desktop version of ABP.
The thing people like a lot of the times is that microsoft offers support, they have it stuck in their head that if you spend money on it, it must be better than a free alternative.
I've worked for several Fortune 500 companies. Support has nothing to do with the decision: Exclusionary contracts do. Microsoft offers huge discounts to businesses that agree not to use a competitor's product. They also regularily check for compliance and there are large fines for any company caught using open source software. Management often parrots what Microsoft says to tell the tech workers who question the policy, but if you ask the right people the right questions, you'll find out the company you're working for entered into an exclusive contract with Microsoft, and that was one of the conditions.
The worst generation ever is the current generation of decision makers(55-65) who are crushing all beneath them in order to save their inflated pension pots.
If there is really a national or international "Demise of guys" among young men, it has a lot more to do with youth unemployment levels than video games or internet pornography.
