It's an arms race. As the malware gets more sophisticated at evasion, the sandbox will be made smarter to counter this. Complexity and sophistication will increase. Eventually, they will get smart enough to pass the Turing Test in order to stay in the game.
You can play Yellow River Kingdom here: JSBeeb. Shift-F12 to boot the Welcome disk and go through the programs till you reach it, or just enter CH."W.KINGDOM" to load it directly. (It's been ~25 years since I last typed that, but that particular bunch of neurons fired as if it were yesterday).
The only way to truly understand C is to read the CPU circuit design on which the application will run. Otherwise you are only assuming what the CPU will actually do with the opcodes generated during assembly. See 6502 opcode 8B (XAA)
IEEE magazines. Still available in print, if you want to pay the extra, or electronic format if you like trees. IEEE Security and Privacy and IEEE Software work for me. And if these are too lightweight, there's always the IEEE Transactions on $SUBJECT.

how did they do that ? ( It always bugged me)
As time progresses between vsyncs, the CRT electron beam scans left-to-right, then moves down a line, then left-to-right, until it hits the bottom-right - then it starts again at the next vsync. You set the video controller registers to mode A before the first line hits the CRT. A bit later, but before it reaches the bottom of the screen, you push new values into the video controller registers changing it to mode B; all the remaining lines are sent to the CRT in the new mode. You just have to make sure that the video controller register values get changed at the right point during each frame, and make sure that the mapped video memory contains data in the right format either side of the mode 'boundary' (although no boundary really exists). You can change mode more than once per frame if you want.
You could always read the Elite source code to see how Bell+Braben did it.
I don't know where you have worked, but The Open University is very highly regarded everywhere I have worked (large companies, household names), and by extension its graduates enjoy the same reputation. The fact that its graduates have shown the enthusiasm and work ethic required to complete full-strength degrees in their spare time reflects well upon these people when assessing their worth to a company.
Even good old Oxford is branching out into online learning these days; I do not think you would consider them a second-grade diploma mill. Unless you are one of those Cambridge types, of course:)
Every one of these "Big Brother" TV programme will just show groups of people sitting around in different houses, all watching different "Big Brother" TV programmes. It will be quicker and cheaper to just replace all televisions with mirrors so we can watch ourselves.
What if someone else posts a picture in which you are present? Odds are that you have been to a family or social gathering at which someone has a camera, and has later uploaded the photographs. Avoid Facebook all you like, but if friends and family use it you are likely to end up on there whether you like it or not.
Apple dominates the premium priced market, not the premium PC market.
Indeed. I suspect most of the premium PC market is taken up by self-build gaming PCs, which of course don't show up under any PC manufacturer's sales figures. A sub-$1000 PC covers everything that most home and office users want; people who need something more tend to know exactly what they want, and don't mind fitting it together themselves.
Not really a problem. Every n releases you push a complete patch - a bit like key frames in MPEG. People who keep their stuff reasonably up-to-date benefit from the smaller patches, those who don't just have to go back to the 'key frame' equivalent.
And on the client - the latest version on the host is effectively the sum of all the diffs up to that point. OK so there is not enough information there to revert to an arbitrary earlier version, but usually we don't revert to older versions of executables. If we absolutely have to revert, maybe to undo a bad update, we can always just download a complete version of the required version.
What if Kennedy had set a lesser goal, such as orbiting the moon?
The Russians quite probably could have achieved with with Soyuz-based
technology. We "know" this, sorta, because recently someone proposed
putting a Soyuz capsule around the moon for a rich billionaire with $100m to spare.
The Soviets did have the Luna programme - including Luna 10, the first artificial satellite of the moon. Interestingly, they focussed on robot exploration of the moon and remote collection of samples - probably closer in principle to the methods that will be used for future exploration of other planets in our solar system than manned flights.

An interesting approach - I wonder if this would also work as well on compiled bytecode like .NET or Java uses?
