If you have SE Linux running with a strict policy, it just doesn't matter if they do log in as root. They'd have to get into the correct role and level as well, which would be blocked.
Even before levels were added, there used to be SE Linux systems on the net with public root passwords. (one Gentoo, and one either Debian or Red Hat) You could log in as root, look around a tad, append a message to a file, run a few processes... and that was about it. You couldn't load drivers, reboot, read log files, install software, etc. SE Linux locked the system down good and hard.
Prior to the last few elections, red was always used for the democrats. At the time the republicans favored freedom more and the democrats were all about big government, so the association of the democrats with the reds (communists) was fitting.
Scan the files as you load them onto the device. Do something appropriate, such as:
a. When the user plays a bad file, substitute a file containing an error message. b. Automatically delete the bad file. c. Prevent selection of the bad file.
We're lucky that Ogg Theora was stillborn, because normal operating systems use file extensions to determine icons and players. If ".ogg" gets an audio icon (it does) and starts an audio player (it does), then it can not also get a video icon and start a video player.
If you really must have the low-quality Theora experience, you can use the ".avi" extension.
BTW, "Vorbis" does not exist. It got renamed. Languages evolve. In the English language, the codec found in *.ogg files is now called "ogg". Deal, OK?
It runs the very latest kernels just fine. Excepting some very rare pre-release versions, I've never had any trouble running the very latest developent code.
Not that my machine isn't a museum piece though. It's PPC!
Unpopular machines don't have many developers. Nearly nobody can test on the hardware. 32-bit SPARC has roughly 1 developer, PA-RISC might have a couple, MIPS and 68000 each have several...
Consider yourself lucky that the 68000 is supported at all. That chip has no MMU. NetBSD refuses to touch it, but Linux at least has a port. (in case you meant 680x0, the "m68k" port that uses an MMU, that's done by roughly 1 or 2 people)
With even Apple and Sun going x86-64, the future is clear. It's x86-64, not x86. Nobody wants to screw with x86 anymore.
They actually added a Secure Digital port for Windows. This is yet another hole that allows water and dust to get into the laptop while reducing the strength of the case. It also costs money. The "Secure" part of Secure Digital is of course DRM, which is also offensive.
Microsoft could have been easily locked out by choosing a big-endian CPU. At best, a stripped down version of the bare OS might be made to run in big-endian mode. (the Xbox360 may be so, or perhaps Microsoft runs PowerPC in little-endian mode) None of the normal apps are tolerant of big-endian mode, especially when exchanging file formats and Windows-specific network protocols with the rest of the world.
We'll be seeing every one of these laptops with a copy of Windows, with Microsoft once again benefiting from the network affects of unauthorized copying.
Currently, there is seldom anything to ensure that these people leave the company in a sustainable state.
Fix:
Every day, grant a small amount of stock which vests 5 years later. The stock continues to vest even after they leave. Thus they start getting paid 5 years after they show up, and continue to get paid for 5 years after they leave. If they work from 2002 to 2009, they get paid from 2007 to 2014.
Maybe have multiple vesting periods: X shares that vest in 6 months, 2X shares that vest in 18 months, 2X shares that vest in 3 years, 3X shares that vest in 5 years, 2X shares that vest in 7 years, and X shares that vest in 10 years.
The same problem exists for politicians, who are apt to do very unsustainable things just prior to an election. I don't have a fix for that though.
We took a wrong turn when we closed down all the orphanages.
Not that life in an orphanage would be good, but at least the conditions can be monitored. Foster homes are places where kids get abused, and there isn't a damn thing that can be done about it.
This idea that we can supply substitute parents is complete nonsense, at least for the older kids.
Another part of the problem is that kids are needlessly getting taken from their parents. There are perverse federal financial incentives that actually encourage this. Mere anonymous reports are often enough to cause it, especially since a legal defense costs tens of thousands of dollars.
With the above issues dealt with, there wouldn't be a "need" to have kids adopted by people who have their own mental/social/sexual/behavioral problems.
Without marketing, will I starve to death? No, of course not. I will seek to buy food.
Will I not have a car? No, of course not. I will seek a place to buy one.
I might not buy a pet rock, chia pet, or similar. Oh well. That's a gain for me.
We could really use more stuff like Consumer Reports, but funding is difficult.
A good start though: strict truth-in-advertising laws. Today it is considered "free speech" for a company to lie about their products, subject to very few limitations. If the soap gets whites whiter, there ought to be published research indicating so. If a product is "the best", it ought to be truly the best from the consumer's viewpoint in at least one normal and legitimate way.
Unfortunately, you can't "drop" anything from something in orbit
Well, I never mentioned orbit. In that case, "drop" roughly means to accelerate in a direction opposite to your ground track.
The expectation is suborbital, like an ICBM. That works rather well. You don't get into orbit anyway without a course correction specificly designed to produce an orbit; any simple trajectory leads you right back to the Earth. Time to impact is somewhere between 20 minutes and a couple hours, more if you want extra energy.
If you take a big long trip for even more energy (at a cost of some time), orbit is not really anything to think about. You do general space mission planning, same as for any other deep-space trip. Comet-like orbits would let you have a steady supply of objects making high-speed flybys of Earth though, any of which could be divirted to strike a target on reasonably short notice.
Impact with a large bird would probably wipe out the ICBM. Maybe even a very small bird would do.
Imagine it the other way around if it helps you. Imagine the ICBM is motionless, and the bird is at mach 20. (equivalent, by relativity) Remember what a chunk of foam did to the space shuttle.
Hey, that would do the job nicely. We can use space shuttle foam.
Remember, the Patriot missile was an anti-aircraft system. In the anti-missile role it's like the dancing bear or the piano-playing dog; we are delighted that it works at all.
A recent upgrade to the Patriot system provides more THAAD-like missiles and better software, but it's still a system originally designed to take down slower-moving aircraft.
Now we have THAAD, supposedly for short-range and medium-range missiles. It'll probably do a decent job on the ICBMs as well, which is better than we had before. Like the Patriot system, it will get upgrades. Like the Patriot system, the lessons learned (hopefully not via cratered cities) will help us to design the next generation.
"the general idea that any missile that can "catch" another missile has to be much more sophisticated, expensive, and reliable"
Oh please. The incoming missile is rather predictable, as it must be. Evasion will be quite limited by fuel supply (normally there is none) and general inability to detect the THAAD. The THAAD gets help from the ground-based rader, does not have to survive re-entry heating, and does not need to carry a nuclear warhead.
We can use hit-to-kill like THAAD. We can use ground lasers, orbiting lasers, and airborne lasers. We can use sabotage of the enemy equiment, physically or by screwing up the software. We can use diplomacy. We can use the nuclear non-proliferation treaty. We can have a sneaky sniper on enemy territory shoot an ICBM right at launch -- a hole in the boost rocket will do the job. We can use an X-ray laser. We can use economics as both carrot and stick. We can export out culture to reduce misunderstanding and general hatred in the long term. We can use radar-controlled heavy machine guns to stop incoming devices.
As a final protection, there is always the cave 10 feet underground stocked with calcium and iodine supplements.

Not all audio players can handle video. Not all video players are any good for audio.
If the user clicks on something.ogg, should they get an audio player or a video player?
What kind of icon should the file get? Does it get an audio icon, or a video icon?
If the user does "file - open" in an audio app, should they see the *.ogg files? Some may be video, which makes them unsuitable choices.
Ogg Theora is stillborn of course, so this question is moot. The *.ogg files are audio.

STOP is not the only signal for pausing a process. Linux also offers the signals TSTP, TTIN, and TTOU. That's 4 to choose from!
/dev/mem.
You can also attach a debugger, suspend-to-ram, suspend-to-disk, trap into a kernel debugger, or just edit
GNU radio should be able to be the modem, in software, given merely a transmitter/receiver/DAC/ADC setup.
:-) Maybe that too can be faked in software.
How do you get a SIM card into a PC?
The states don't care about you.
They have eleventy-billion lines of COBOL to care about.
They actually added a Secure Digital port for Windows. This is yet another hole that allows water and dust to get into the laptop while reducing the strength of the case. It also costs money. The "Secure" part of Secure Digital is of course DRM, which is also offensive.

Word suuports "art borders". Users can choose from a wide selection of images selected from 1980's western culture. Does this get exported properly?
If I can't get the candycorn borders, no deal!
Is there some other Sony, maybe not the famous one?
The Sony I know does not play nice with protocols, file formats, or even CD audio standards.

You get:
1 disabled SPE
7 working SPEs (each has 128 128-bit registers)
2 PowerPC 64-bit w/ vector units (one PPE is two-way SMT Power 970)
That is 9 CPUs total, 7 weird and 2 normal. Linux mainly runs on the 64-bit PPE cores, but there are ways to run code on the SPE cores.
Decent SPE documentation is nowhere to be found AFAIK. Perhaps it can be derived from a gcc port.
Example:
Get a random sample of people to try all the Chinese food in town.
If a statistically significant number of people think Ho-Lee-Chow's food is the best, then it is.

That's a whole other issue, fortunately rather uncommon.
Such kids need to be very good at playground fights.
It's rather sad that an adult would bring a kid into such a situation.
And yes, it's sad that kids sometimes suffer as a side effect of society's efforts to discourage such nonsense.

There is now a laser-based system that nicely takes out artillery shells, morters, and small rockets.
You can sometimes use missiles for boost phase. That depends on geography.
Launch from center of Russia or China: no.
Launch from North Korea: yes. (from ship, plane, Japan, South Korea, etc.)
BTW, only a fool would want to rely on one single intercept method. Numerous anti-missile ideas are worth implementing.
