Next you know the young whipper-snappers will take "variables" and call them "dynamic constants"

In Bluetooth (especially Bluetoothe Low Energy (BLE)) they already reanamed them. They call one a "characteristic" (when you include the metadata describing it) or a "characteristic value" (when you mean just the the current value of the variable itself).

If the two-engine planes are such a risk, how the hell have they got air safety certificates?

Unless, due to scheduling issues they intentionally want to run the plane with broken engines, I don't see any good reason why it needs four engines.

Fair enough, buy American - especially when the A380 is more expensive. But given that it is a completely custom fit out, I don't see why the smaller size of a 787 should be a problem either.

The 787 would make it practical / possible to fly into smaller airfields too. And be much, much cheaper - to purchase and run.

I thought the point of the charge was to make the "wooly" side-fibers of the strands wrap around the prey's limbs and/or the microscopic irregularities in the exoskeleton, tangling to it. "Tying" the fibers to the prey would have a similar binding effect to gluing them to it, without the need for glue, and lots of little fibers could make a very strong attachment.

(Stretching fibers made of long chains makes them stronger by aligning the chains along the direction of the stretch.)

Why are they still using C to deal with network protocol? Is the performance so critical that it's worth all the troubles?

Also, because there's a lot of C code that has been in heavy use, and tested for correctness, for decades, suitable for reuse with substantial confidence that it's correct (though you check it anyhow...).

Let's see you find code like THAT for a language that hasn't been AROUND for decades. B-)

Comment: For starters, because it's transparent. (Score 1) 46

Why are they still using C to deal with network protocol?

For starters, because it's transparent. The "K&R compliant assembly laguage", as one of my former colleagues once characterized it, translates to object in a clearly understandable way (especially if you turn optimization down or off). Though it gives you more opportunities to create bugs, it makes it hard for the bugs to hide from inspection.

The "higher-level" the language, the more it takes over and inserts its own stuff between you and the metal, and the more opportunity for that to inject an invisible vulnerability - which you might have trouble removing even if you DO discover it.

Meanwhile, many of the things "higher-level" languages protect you from can also be detected and flagged by both modern C compilers and code examination tools - starting with the venerable "lint".

I can guarantee you that if the Govt. left it up to drivers to get the proper training and instruction on how to operate vehicles safely, people wouldn't do it.

Interesting claim - since it doen't work that way for guns.

Where the government requires training, most gun purchasers take the minimum required, then stop. Where it doesn't, most people start with the course recommended by the gun stores (which is far more comprehensive - and more focussed, with less time spent on political indoctrination B-) ) and also do substantially more range time, until they feel adequately competent. (Then there are those that get interested in shooting as a hobby...)

A similar effect is the reason police normally don't shoot at private ranges simultaneously with civilians. Most police are embarrassingly HORRIBLE shots and pistol-handlers - because they do only the minimum training and practice required by the department (which has lots of other stuff for them to do while they're being paid for their time), and almost never have to actually fire their gun during their work.

For the 5 1/2 ton towing capacity (which also translates to "won't blow the engine head gasket towing a loaded trailer up CA 88 like the van did" - turns out they designed that vehicle's engine with the cylinders too close together so this one pair had a very thin piece of gasket between them,..).

Seriously, why is this guy's comment flamebait? Apple does this. They move billions of euros through Ireland to avoid paying any taxes.
I find it curious that so many Slashdoters have no problem when a company uses all the advantages of society and yet refuses to contribute to keeping the society going. In this case, literally racking in billions upon billions in profit while barely contributing to the tax base.

Why do you think this is a good thing?

I work for a small company. We have only about 80 people. So, while we may not make as many jobs as Apple does we do pay our taxes. We also still have a profit.

But you did suggest they're doing this "so you don't have to", which has the connotation that they're doing us a favor. I'm pointing out they are only doing themselves a favor.

The whole point of a free market sale is that you're both doing each other a favor. You'd rather have a trip home than the money in your pocket, and I'd rather have the money in your pocket than the time/expense it takes me to give you a lift. It is a service industry even if it isn't charity.

Since we can't exactly force rationality into individuals, nor can we force buyers to not give their money away, the pragmatic solution is to limit what is considered a rational maximum price on sellers. If you as a buyer still choose to pay more, that's all you, man. Society already warned you.

How can a buyer choose to pay more if the government regulates the maximum cost of a ride?

Hey, if word gets out that people are willing to tip extra, you'll get your results of getting more drivers out there and more people getting home. So please, if you really believe what you're saying, go out there and leave those big tips yourself.

Tips are just part of the price if they're negotiated in advance. If they aren't negotiated in advance then they have no impact on the availability of the service. Nobody is going to go out in a storm hoping that somebody is going to be nice and give them a big tip.

Tipping after a service is rendered really doesn't make that much sense economically unless you're a regular customer (in which case you're really just tipping way before the next service is rendered, which is why it works). Having payment based on performance certainly makes sense economically, but only if both parties are bound by the agreement.

I would, and do, buy the nexus and sony phones. The nexus 4 is upgradable to Android 5.0, and the xperia z1 is still upgradable to 4.4.4 i think.

And the Nexus 4 would still be under contract if you bought it on a 2 year contract on the last day that it was sold. Let's see if it gets the next update.

That said, Google has been getting better. The Nexus 4 is the longest-supported Nexus phone to date. The previous ones didn't get any updates after about 1.5 years from their first sale.

Free market guarantees shortages that is it's function. What you are really saying is if you can not afford it, meh, fuck you, ha ha, die in the blizzard.

Not being able to afford something doesn't mean that there is a shortage.

And I'm not suggesting people that can't afford a cab should die in a blizzard. Free markets and socialism are orthogonal. You can have either with or without the other.

If you're going to die in a blizzard, then call the police. They won't charge you to respond, and if we're talking a really big issue then the national guard should be bussing people out of dodge.

There is also no need to have poor people in a free market. You can give people a basic income so that they can afford food, and then let the prices reflect scarcity, so if there is a big chicken shortage the poor people can just switch to eating hamburger. You don't have to keep the price of chicken cheap and then watch as every store runs out of it anyway.
