What it offers is thrust without fuel, which does not violate conservation of energy
But it does violate the conservation of momentum, which is just as fundamental. From Noether's theorem, we know that the translational symmetry of the physical laws implies the conservation of momentum. If we believe in this symmetry, then we're stuck with the conservation. Which means that if this conservation is broken, then by implication the laws of physics must break translational symmetry. There's no escaping that, and there's certainly no evidence for it other than this vanishing-in-the-noise experiment. If it were a real effect, it would be earth-shattering.
They probably make many different versions, and then spend weeks trying to get everyone - from marketing through to legal through all the talent - to actually agree on them.
Well, if your definition of a "reasonable editor" is one that can handle python's whitespace madness, then sure. However, there are plenty of editors that don't, or don't quite handle it fully, or don't squiggly-underline whitespace that isn't correct. In my opinion, those editors are perfectly reasonable for all other programming tasks, but are suddenly unreasonable for python.
I posit that the problem is with python, not with these editors.
His (or her) point is that gold is a scarce, divisible, unfakable and more or less immutable commodity. Once you've got some, it lasts forever, without changing state. This means that it becomes an effective measurement of the value of money.
On this planet there is a fixed amount of gold. You can have a crack at determining the value of any given currency by finding out how much gold you can buy. Well - that's the theory anyway. However, though there is a fixed amount of gold, the other thing that money really means is far from fixed. And that thing is the amount of human endeavour and natural resources available on this planet.
Well..... You download a DMG, which is mounted (not installed yet... but I guess you didn't mean to say "you install it", right?). If it's something that needs a whole bunch of drivery type of things, like installing VirtualBox for example, then there's an installer that you run. Otherwise, the installation process literally is just copying the application into the applications folder. You don't even have to do that if you don't want, you can just run the application right from the DMG. I honestly don't understand how this is the equivalent of a ".bin" installer Linux.
Uninstallation is just deleting the application. You do make a possibly fair point that application settings may be left behind when you uninstall. But really, why does this matter? I mean seriously, no-one cares that there's a small plist file kicking around in ApplicationSettings. Aperture, for example, stores 250Kb in there. BetterSnapTool stores 8k. GuitarPro stores 60k. You get the idea. It just doesn't matter. Should the settings be inside the application itself? Well, possibly, but there are permissions issues around modifying the application, so it's just simpler to put the settings in the user's home folder instead.
Microsoft, of course, somehow manages to store 30Mb, but that's not really surprising. There's a folder in there called DRM too... scary... It looks empty, but I bet it isn't really...
You're kidding, right? Restart often? Like, the whole machine, or just the JVM? What class of problem admits restarting often as part of a viable solution?
The nonce+hash algorithm exists to prevent eavesdropping on the network traffic. This problem is solved better by just using SSL traffic for everything, since nonce+hash has the disadvantage that since the server never sees the actual password, the only authentication process that can realistically be supported is a local password database.
Plus, of course, phishing has nothing to do with either method. Phishing is just faking the login page, and sending the credentials elsewhere.
But... but... Apple sell DRM-free AAC files through their store, which they managed to do despite the music industry guys hating it.
So you're saying that Apple are going to put back all the infrastructure required to put DRM into the music they sell, despite all the trouble they presumably went to in order to take it out? What on earth for?
I very much doubt that is true. Without Wozniak, Jobs would have found some other techinically adept guy, and made squillions of dollars building computers. There's no doubt that building computers was Job's vision, and at the time it was a unique one. Being a technical guy, and doing amazing things with parts, was not a unique skill then, and it certainly isn't now.
He is right about that damn headphone jack though.
Look man, you just don't know how to use your operating system. Perhaps you need to go on a course. All the things you're complaining about aren't problems, once you know your keyboard shortcuts better. Windows alt-tabs through everything, which doesn't scale well with large numbers of windows. Mac alt-tabs through applications, and alt-backticks through windows within that application. Different approach. Being a mac, of course, there are loads of really nice tools that you can install to customise the behaviour of your system (contrary to popular belief). In your case, I suggest that you install Witch (Here). Yes, it costs money. The horror. It's nearly the price of two beers. Explain to me again why the hard work of software developers should be available to everyone for free, again? I forgot the details on that one. If you don't like the maximising behavour, there are tools to sort that out for you. I use BetterTouchTool myself.
It's ironic that someone who wants to install Linux, which pretty much entirely consists of little plugin tools to make stuff happen, hasn't bothered to go looking for the little plugin tools that can customise OSX for you.
Regarding your broken MBP, that's a shame. However, computers do break occasionally, and since you haven't bothered to look it up, you can hold down Cmd+V for a verbose boot, or Cmd+R for the recovery console, which will actually download an entire OS install from the internet and re-install your entire machine for you if you want - including pulling in your time machine backup (you have a backup, right?). Or, if it's something less drastic, you can start the mac in single-user mode (Cmd+S), or try some of the other tools from the recovery mode.
I mean, I get you don't like OSX, and that's fine. But nothing in what you wrote is actually correct, and so I hope I was helpful, and not too patronising, in correcting you. And what exactly don't you like about installing stuff on a mac? Sure beats windows installers - and apt-get on Linux just craps out half the time (I guess I'm doing it wrong... touche...). Android follows more of the OSX model, which is that everything lives in the application package, and you don't bother with sharing components between applications because it causes far more problems than it solves.
PoE for a tiny device like this, with built-in wireless, doesn't really make any sense. What makes sense is to stop trying to cram Linux into these things, and design them for low-power usage from the ground up. These are so-called "Internet of Things" devices, and will be single-purpose embedded systems. You do not need Linux to do that, it just gets in the way. I wonder how much current it needs to run, and how long it'll last on batteries, and whether or not it has any low power modes.
if they only thing you want to do is get a list of all files matching a pattern. There's no text wrangling, you just start typing commands.
This is only because you already know bash's obscure command system, and that it doesn't have object names or a structured data interchange format (which, if you came from a programming background and had not been exposed to bash, you might be surprised about). In actual fact, if you are learning bash, you need to look up its obscure command system. I mean, sure 'grep' is a short word, but you can hardly argue that the word 'grep' isn't obscure.
"ls" is a great example. On unix, it's more or less impossible to take the output of ls, and break it apart into sane information, like file size and filename. As soon as you get spaces in filenames, you're shit out of luck.
Powershell is a brutally ugly thing to use, but the idea of piping information around that isn't just lines of text is great. I just don't think that it's been implemented well yet.
I do see your point. However, I think a well-written guide is superior to a video, no matter how good that video is. And I think that this is true always.
This is because:
a) You do not have to bother to pause a written guide.
b) You can print out a guide, and use it for reference later.
c) You can cut & paste from text - very important for software.
d) A guide can, in a pinch, be automatically translated.
e) It is far far easier to refer back to a particular point in a guide, than it is to find a particular point in an hour-long video.
I'm sure that if I really sat down and thought hard, I could come up with whole alphabet of other reasons too.
The point I was rather clumsily trying to make, was the reason that videos are becoming more prevalent, is not because they are superior - they never are, no matter how good - but because they are easier to make. All you have to do is sit down with a headset mic, and a screen recorder, and away you go. That said, I would draw a distinction between 'guides', and (say) those cool videos on youtube that those maths guys do. Or documentaries, or whatever. The crucial distinction is that one is not expected to be watching the video in order to learn how to *do* something. That's when they become much less useful than clear pictures, and well-written text.
As a further data point of one, I have had the experience of transferring from an audiobook of a novel, to reading the physical copy, halfway through the book. Reading the words on the page was a vastly more immersive, and visual, experience than listening to the audiobook. I found that much more of the text made it into my brain via printed words, than did through the spoken word.
I really don't think that's true. A well-written guide, with clear and well-chosen screen-shots, is more valuable than a video every single time Especially for software tutorials, not least because it's extremely difficult to cut & paste from a video. Plus you have to pause the damn thing all the time if you want to follow the instructions. The trouble is, that it's very easy to make a video, and very hard to write properly. The fact that it's also very hard to speak clearly, be concise, and have a voice that doesn't irritate, seems to escape the vast majority of idiots that make these videos.
A case in point, ifixit instructions. The day ifixit start posting video guides, is officially the last day of good sense on this earth.
I'm sure you can, but it's not a 'don't even install it' type of scenario. I certainly don't install it anymore, but lately I've noticed that HTML5-driven ads are starting to eat CPU, just like flash used to.
I don't think we've moved forwards here at all, unless you particularly hate Adobe, that is.

Well, Aristotle had some basic natural laws that turned out to be a bit, well... wrong.

People with a sense of humour. It would certainly make me laugh, anyway.
Use Java and restart often.
You're kidding, right? Restart often? Like, the whole machine, or just the JVM? What class of problem admits restarting often as part of a viable solution?

Shell scripting is for system administration, quick hacks,
Which, of course, explains how most of the underpinning of Unix configuration is indistinguishable from a quick hack.
