Summary: Lots of improvements in a number of areas can make a big, big difference.

Since ~2008 I know they've increased the energy density of their 18650 cells by 20-30%, which would correspond to a 20-30% increase in range no matter what. After that it starts adding up quick.

I wonder if they might end up restarting roadster production. For a small car manufacturer that could even be fairly logical - produce as many as you can for a relatively short period of time(few years), then shut down production for a few years to let the demand recover and grow.

Perhaps more importantly, increasing the range of a car from 250 miles to ~400 also means that you could put a smaller battery pack in that costs nearly half as much, making it more affordable.

It also helps show the longevity of Battery Electronic Vehicles. Though it's only been two years since they stopped producing it, they're still producing not just maintenance parts, but serious upgrades.

What on earth makes you think that NK has to have the native talent? The didn't figure out how to make nukes on their own either. They didn't home-grow their substantial currency counterfeiting operation, either. They likewise don't design and build their own military equipment. But that doesn't stop them from having nukes, from doing big business in phony currency, and sinking other people's ships.

Thank you, Brave Warrior for The People's Democracy! Your commemorative Kim Jong Un medallion will be delivered to you. In person. You may wear it your choice of northern work camps, where you may be able to trade it for a piece of moldy cabbage before you die.

Sure they did. They stole time from millions of people. They deliberately screwed with the expectations and plans of millions of people, all for a little bit of cash and bragging rights among their fellow assholes.

You're right, all those people should have chosen to buy fun, well-developed, richly supported gaming platforms from one of the many providers who offer open source, freedom-minded, anti-IP, systems that have a large selection of really cool massive multiplayer games with giant networks supporting all of that activity. There are so many to choose from that I'm sure it's why you just didn't have time to list them.

It's idiots like you, who think that businesses, networks, people's entertainment time, and the like "aren't real" that give comfort and encouragement to idiots like the guys who pulled this. They did it to be dicks, just like other dicks might throw a rock through your window and nail your TV right before you were going to watch the World Cup match you've been waiting weeks to watch with your friends. Or, in a closer analogy, waiting until moments before the game starts, and then cutting the cable that services your house or apartment building.

Let me guess: that soccer game's not real! They're not at the stadium in person, so denying them the chance to watch it as they planned isn't actually harmful! Destruction of the time someone plans to use in a certain way is a theft more real, in many ways, than stealing physical objects. You'll never be able to replace the time. Which is one of the reasons these guys are dicks. Deliberate, purposeful, not noble in any way, dicks.

That needs a big 'citation needed' next to it, but:

You don't understand risk analysis. He's investing a very small proportion of his wealth in something that may have massive returns. The probability of said returns may be small, but that doesn't make it a bad investment if the potential payoffs are huge, as long as you can afford to take the loss if it doesn't pan out. Most people with his money will invest a few millions in a few fringe ideas, because it only takes one to pay off to more than make up for your investment. The majority of his portfolio will be in relatively safe investments with a close-to-guaranteed return, a bit will be in risky venture.

You missed decay, which is the most common form of nuclear reaction on Earth. Proton capture can technically be thought of as fusion (fusing a hydrogen nucleus with something heavier), but it generally isn't referred to as such. Neutron capture is not fusion and a lot of LENR reactions are neutron capture.

Insertion sort is terrible for the use cases the grandparent described. For one thing, it requires allocating a new data structure for storing the data (an immediate disqualification for a lot of embedded tasks). Second, it has much worse cache interaction because it requires searching the second array. Assuming that your target is an array, then it also requires a bit memcpy for each insert, which means that it likely requires a similar number of memory operations to the bubblesort, but with more temporaries. You can do a bubblesort in-place, with good cache locality, and only a handful of registers (insert base, top, current, and two for holding the current elements). If your CPU has 8 GPRs then the space requirements of a bubblesort are effectively zero - no memory required.

That's only if you don't have the requirement to sort in place. Bubblesort is also a good way of getting students to start thinking in terms of induction. Each step in the bubblesort leaves the array more sorted than it was before.

Insertion sort is one of these good-on-paper algorithms. It's very fast if insertion is cheap. But insertion relies copying unless your data structure is a linked list. If it's an array (worse, a contiguous on-disk store) then that copying can be very expensive. If it is a linked list, then you're going to have very expensive search (sure, you may still be O(log(n)), but that constant multiple is going to be hurt by the fact that you're hammering your cache and killing your branch predictor).

Teaching algorithms separately from data structures is one of the biggest flaws in modern computer science education. It's impossible to reason sensibly about one without the other.

Bubblesort has two advantages. The first is that, because it's only swapping adjacent elements, it has very good locality of reference (which means better cache usage, but can also mean more amenable to fine-grained locking). The second is that it performs well on almost-sorted data (that O(n^2) is the worst case - it's closer to O(n) if your inputs are mostly sorted). These two mean that there are situations where bubblesort can be useful, though they're quite rare.

What is that measuring? The fact that it doesn't say means that it's meaningless, but it looks like they're comparing number of ships, so a coastal patrol boat counts the same as an aircraft carrier...

A statistic that floated around earlier in the year when Argentina was grumbling about the Falklands again: one of the battleships that the British were sending to the area could fire, in one minute, more munitions than were fired in the entire 1982 conflict. I'd imagine that the differences between 1945 and now are even more pronounced.

One constant trend has been that soldiers are less expendable. In the first world war, sending men to walk slowly towards machine guns and throw a grenade if they survived to get close enough was their patriotic duty. By Vietnam, having large numbers of soldiers come back in body bags was politically unacceptable.

In the 1940s, Japan was flying aircraft loaded with bombs into American warships. A few years later, people realised that you could design aircraft for this purpose and make them a lot lighter and able to accelerate more if you removed the human pilot. They called them anti-ship missiles.

The fighter screen that fleets needed to protect themselves from aircraft in the '40s is now replaced by anti-aircraft and interceptor missiles (and dumb projectiles). In the next generation of ships a lot of this will be replaced by lasers, which reduces some of the resupply need (you can't run out of laser ammunition on a nuclear carrier unless your ship is so badly damaged that it's not a good idea to be anywhere near it).

Gradually, a lot of the roles for aircraft are being replaced by drones, which means that you need smaller carriers. They don't need to house as many pilots, they don't need as many support staff.

Another part of this trend is to replace reusable vehicles with single-use munitions. Fighters are more expensive than missiles, so you spend a lot on maintaining them. Drones are a lot cheaper, so you can afford to fly them for a couple of missions and then scrap them (explosively, near someone you don't like).

Comparing numbers, as the grandparent did, is completely meaningless. You may as well compare the size of the air force to the number of soldiers Napoleon had.

There are basically only three decoders that cover most of the market: Microsoft's DirectShow filter, libavcodec / libavformat, and QuickTime. Hardware decode doesn't help much, because you still have the same software path as everyone else doing the de-encapsulation and file parsing, which is where the exploitable bugs often show up. If you have vulnerabilities in each of these then it's not generally hard to hide them all in the same file, as the codecs aim to be resilient to corrupted data so will usually just drop a frame or two for the exploits aimed at the other implementations.

Oh, and libavcodec / libavformat are used in Android (and in a lot of iOS apps, as AVFoundation doesn't always expose useful APIs), as well as in desktop browsers, so they're a pretty good target to aim for.
