A good hammer, a good manual drill, a good screwdriver, will last a lifetime. Many people, however, invest in pneumatic hammers, electric drills, and bit sets even though they know it will break. There is myth of how we own records, but I am old enough to own LPs and CDs, and let me tell you that the lifetime was limited, and they were difficult for mobile devices. Transferring them to tape was a significant loss of quality.

Comparing a phone to a plunger is silly, and makes me question the cognitive abilities of the person making the analogy.

Everything is a trade off. My car is so complex I can't begin to figure out how to fix it, but I do have a diagnostic tool on my iPad that I could not possible afford 10 years ago. My watch, and iPod Mini, is obsolete but it still tells me the time. As long as that is all I want it do it is fine. I used my 3GS over the summer as a roaming phone. Slip a sim card in it and I was good to go. As long as I wanted it as a phone, I was good to go.

Yes, you can't take stuff apart. OTOH I was one of the few people I knew that actually soldered computers to repair them, rather than just plug and play with a new board. Yes, some phones are not upgradable to current software, but many consumers seen to happy to make that choice to have a cheaper phone or a phone with other features. I can even see the current situation where you pay per page for ink is an option that many people would prefer.

Certainly there is a loss when we do not have a choice, but I think in many cases we still have a choice, it is just that we do not want to pay the real or opportunity costs for that choice.

Tesla is part of the old boys club and they are playing it perfectly. First they create an exclusive product to sell to a privalidged few. Then they say they are going to create a product for anyone, any day now, and start crying how the states are oppressing them and keeping them for helping the impoverished masses. Then they play the old game of hustling states and end up with a deal that will result in the siphoning of 1.3 billion dollars of taxpayer money directly into Tesla's pocket, even if they never reach the targets of employment or sales. The only part of the old boys club they don't respect is that it fraud is a two way street. you can't take, you also have to give. Dealerships were one way for the car companies to spread the wealth back to the friendly politicians in the states. Tesla is saying it is all theirs, and they are not going to share.

Again, nothing against Tesla or electric cars, just saying they are not a knight in shining armor that is going to save us from the politicians and climate change. They are just another company trying to maximize profit and take whatever welfare they can get.

To be sure, like most legacy industry, there is likely no ability to innovate. Think of american cars in the 70's. Energy generation is still powered by coal, coal plants are still being built, and we are still fighting over emissions. I don't know if a report saying that the industry needs to innovate will do any good. Making coal fired plants too expensive to build by requiring them to be clean might have an effect, and force the industry to innovate.

In any case, the incumbents are clearly show massive inefficiencies. In locations where electricity is sold competitively, prices can vary by 25% or more. This indicates that there is quite a bit of wiggle room in pricing. However, what we are really talking about here is volume. Without volume the incumbents firms that sell power, not produce it, are going to get squeezed out. Producers will shut down plants, and that may have long term effects in energy security.

What is really an issue is the grid. There is at some point going to have to be a charge for hooking up to the grid. Already people on low cost plans that do not use enough electricity pay an extra fee for administrative and grid costs. This is where legislation will come in. Are we going to require a house that is self sufficient to be connected to the grid? Are we going to allow houses in more expensive locations, be it rural or more prone to damage, to be charged more to be connected to the grid?

Ah, the joys of 3 VT100s on your desk.

And if you took the lid off, you could grab the CRT yoke and the cheap varnish holding it to the tube would crack so that you could spin the image on the screen.

That way, you could have two of your three terminals sitting sideways on your desk. Or even upside down!

Black holes are mathematical constructs that allow us to explain certain phenomena. We make certain observations the are consistent with the mathematical construct and say it is a black hole. This is not far removed than saying wood has fire in it because fire comes out of wood. For a certain cases, that is a reasonable explanation and a reasonable way to look at the situation. However there are issues if one is going to talk about more objective science. The same issue occurs with dark matter, which is a critical part of explaining the observable universe, but also has issues.

I don't think we can just assume something is fact because it fits with what we know right now. Modern physics was built on quashing the assumptions that infinities and infinitesimals exist. We cannot go arbitrarily fast, and we cannot chop things up infinitesimally small, or measure to an arbitrary accuracy. These ideas were built in to classical mechanics as deeply as black holes.

To be clear I am not saying that black holes do not exist and what we observe and call black holes are not black holes. Just that when we are dealing with artifacts of mathematical models, time could identify them more as artifacts of the model rather than the most useful representation of the observable universe.

All banned books means is that the someone was offended by the book. Not to be glib, but I agree this definition is way to broad. We should be looking at books that were really banned, not just subject to some letter writing campaign by wimpy jerks that don't make any real contributions to society.

For instance, in high school the parts of the Canterbury Tales that could be taught were in fact limited. I might consider this a banned book situation, but my teacher was free to suggest we read all of the tales, even if we could not discuss them in class. OTOH, Ulysses was banned at the US federal level. Now there is a banned book.

The week still serves a useful purpose by tricking kids into thinking they are going to read some naughty bits. The one book that this is valid, and also banned on the US federal level, is Lady Chatterly's Lover. "Some very useful tips; Oh, gardening tips. Mellors was a game keeper. Very good at hedge control; I thought the sex was jolly good fun as well!"

Heinlein is generally credited with providing a pretty good description of the modern waterbed. I was not that far of a prediction, but it was real. He probably provided the best prediction of the internet.

Then there is the rise of very small dwelling, basically just beds, which are becoming popular in some parts, as predicted by the cyberpunk novels.

The real problem with most prediction in science fiction is that is misses a critical development aspect of the technology, or more often the limitation of the applications of the technology. For instance, at this time everyone expected housecleaning to be done by robots, but astronavigation to still be done by hand.

You do know that there is fair amount of evidence that Tylenol causes liver damage and has other side effects that makes it counter-indicated for many people. This has nothing to do with internet trolls because the company has been dressing up doctors with high airs of gravitas to give terrible medical advice and prevent the drug to become widely known as the health risk it is.

In fact I am sure that when people post such things about the danger of Tylenol on boards, those people are considered trolls and maybe even modded down or kicked off.This is the problem with complaining and trying to ban trolls. Trolls are often simply people you disagree with, or simply people who bring up facts you don't want to deal with.

Not to defend trolls, but only to say this is not an internet problem, people should be able to make critical judgements of what they here. For instance, television is full of statements that make no sense. Infomercials, opinion shows masquerading as news, daytime talk shows. Dr. Oz makes false claims, has even been called in front of congress, almost every week. I don't see how rational people are going to believe that gold is long term investment strategy for the small investor. At least with commercials most people know they are being lied to.

Trolls may in fact make the discourse of the internet less enjoyable, but it also has a built in bullshit detector called everyone else. And each of us adults has a responsibility to think critically about statements that are made.

For instance, when I first heard this I immediately asked how could a software update effect the charging hardware. How could a software update effect the ability of the hardware to handle hard radiation. And by what mechanism could the battery be charged.

Of course some of these questions come from a hard science background, not something everyone has. But still isn't the problem that so many in the population just believe and repeat whatever they are told by authority figures. Is the problem really trolls, or that a certain subgroup of people just want to believe in the magical solutions promoted by their revered charlatans.

Is linux so unreliable and prone to disaster that "kill -1" used on a regular basis?

Quite the opposite!

Kill -1 tells a service daemon that is handling hundreds of thousands of simultaneous connections that it needs to re-read its configuration file, without interrupting service even momentarily.

Kiddie stuff doesn't need kill -1. It's only the ultra-reliable stuff in mission-critical roles that needs it.

Suppose you, personally, have a piece of software that controls your artificial heart. Your doctor has discovered that there's a security vulnerability in the silicon, but luckily it can be remediated with a change to the software configuration, so that you don't have to get your chest cracked to fix it. He uploads the new configuration and kill -1's the running software, and it picks up the changes between one beat and the next, never causing you to, you know, die.

OK, maybe that was an unnecessarily dramatic example. A more mundane one would be adding a new web site - you enter the new A, AAA, SPF and MX records, put the new config in the httpd.conf and access.conf files, then you kill -1 the DNS and httpd servers, and none of your other customers have to have their web sites shut down while the new one is being brought up. This happens ten thousand times a day at web service providers all over the world.

Honestly, Smartboards in modern use case is a scam. It is essentially a big mousepad. The reason that most people buy it is because they do not understand basic computer/physics/electronic stuff. I am serious here, some don't understand that they can project on a normal whiteboard. Now one can use a smartphone as a remote mouse to control whatever you want to better than the board.

About the only reason that the smartboard is useful is because administrators like teachers to stand in front of the class and pretend to teach. Although writing on a slate or ipad and having it show up on the board can be better, the teacher standing in front of the room is still seen as the old fashion as the better solution.

If I am honest, though the smartboard software is bloated, there are some things it does very well, although it is still better to not use the smartboard. There was a time when the board itself was interesting to kids, but now they all have smartphones.

So to answer the question, if there is not something in the software that you absolutely have to use, like the math symbols, then don't use it. Download mobile mouse or something like it to control the computer. There are many drawing apps that will allow you, or any student, to write. I have a slate.

I find it to be a bit slow on my 5. It is very slow on my old iPad. This, I think is normal, and it has gotten faster since I upgraded.

As far as the updates, most applications seem to update when a new iOS comes out. I have not seen an inordinate number of updates. As the Apps have to not only deal with a new OS but also new screen sizes, Apps that are not written to run on many screen sizes will obviously have to be updated.

My problem is that Apple is reintroducing the cloud disk service, a la iDisk, but it is not going to available on mac until the next MacOS, which is not going to be available for at least a month. Those who upgrade when they upgrade their phone will lose access to data on the Mac. There does seem to be some feature bloat at the expense of efficiency.

The Force is what holds everything together. It has its dark side, and it has its light side. It's sort of like cosmic duct tape.
