Usually a sign of an impedence mismatch somewhere.
True, although the term ghosting (with no distiction) comes from broadcast television, where it was usually the result of multiple signal paths hitting the aerial out of phase (impedence mismatches cause signal reflections within the cable with much the same result). In other words, even though the result may be spatial on the display, it is in fact a manifestation of a temporal error.
Perhaps display latency would be a better term for LCDs?
Actually, the glass on a monitor is not 1cm thick; its only 5mm or less.
I know this because I use a monitor faceplate as a serving dish (and no, it was never attached to a monitor, it came off an assembly line before being attached to the tube back and being coated with phosphor or aquadag, so its never been in contact with anything more toxic than anchovies).
Its a question of aptitude and time. You may have plenty of time to learn the finer points of HTML; others may have busy jobs, families, or other commitments that preclude in-depth learning of one rather technical subject which, for them, is really just a means to an end. Just like it shouldn't be necessary to learn how to design a microprocessor to use a computer, it shouldn't be necessary to know the ins and outs of HTML to produce what could be done physically with a press of a photocopier start button.
Its not that I think that people shouldn't learn if they can (and to be honest I find those who refuse to learn infuriating), just that they shouldn't have to if it isn't a priority for them. And if someone wants to stand up in public and announce their idiocy to the world, who are we to stop them?
I don't think a space program that is ten years behind its intended schedule and insanely over budget is all that impressive. Each individual launch might be spectacular, but is it really progress?
I'm 35, I followed every development from Enterprise's drop-test onward. And while I'm impressed by the design complexity and the launch footage, I can't help but be saddened by the fact that after nearly a quarter of a century of service, the shuttle has achieved very little that couldn't have been done cheaper and faster with disposable rockets. It certainly hasn't come close to living up to it's promised usefulness, and to me that represents astoundingly poor engineering and management.
Yes, its amazing; but I'm also amazed when my old Osborne 1 (same vintage) fires up. "Amazing" doesn't mean that there isn't a better way...
And SBS kept playing a French film. I've noticed 10 and SBS tend to avoid live news coverage as much as possible, probably because SBS has a tight budget and channel 10 seems to employ retarded monkeys.
The only problem with this idea is that if you sign up to this list you're likely to receive more bludgeoning, and the list will probably be on-sold so you'll get pummelings, beatings and poundings as well.
Microsoft did some market research and found that calling it "Virtual Parts-Of-The-Earth-That-Matter" was just too long. So they assumed the American audience wouldn't notice the difference, and since the rest of the Earth doesn't matter...
This nation was started with a religious belief in tolerance.
I suspect you meant to write "belief in religious tolerance". Sorry to be a grammar nazi, but I'd say tolerance has been observed more sporadically than religiously...
"...we're not talking new equipment to manufacture the phosphors, just changes in the settings of the production line"
It isn't quite that trivial. Changing the phosphor is simple chemistry, true. But remember, I also mentioned the shadow mask, which is the grid behind the glass that defines the physical pixels. If you look closely at a TV you can easily see this grid (some types use an aperture grid instead), but it is near invisible on a monitor. The greater precision required here means that a critical part of the manufacturing process is significantly different, so contrary to what you might expect from casual observation there is little economy of scale for monitors to be derived from mass producing lower resoultion TV picture tubes; phosphor chemistry is merely another factor. Its entirely possible retooling may eventually not be considered economical, especially if the same manufacturer has higer profit margins on LCDs, so I would expect low cost suppliers to be the first to abandon CRT monitor production.
Now I must qualify all of this by pointing out that this is unlikely to happen until the majority of new computer systems are sold with LCD monitors, which I believe is some years away, and I'm assuming there is no replacement technology forthcoming. But even though you (and I, for that matter) consider CRTs to be superior, we are talking about a market consisting largely of people who don't seem to mind ghosting and oversaturation and wouldn't know colour calibration if it bit them on the eyeball; sadly, absolute quality is rarely the deciding factor in the popularity of consumer electronics. So rather than a factor of 10, I think less than doubling the price of CRTs would be enough to make most people switch.
A glossary of CRT terms, which explains the difference aperture grille and shadow mask based units better than I can is here: http://www.able.bg/glossary1.htm
(I should mention that I have an uncle who used to design CRTs for a company called Thomas Electronics and used to bore me to death at family gatherings with the details. I never thought that information would ever be useful...)
I muat point out that there are differences between CRTs in TV sets and those used in monitors, most significantly a finer pitch of the shadow mask and slightly different phosphor composition, which means that a continued market for cheap TVs may not necessarily translate to low monitor prices.
I'm sure that's part of it, but its probably as much the make up of the school populations as the sheer number.
Notice that this kind of thing didn't happen when apprenticeships in mid-teens were more common; apprentices are supervised more closely than students and are given tasks with tangible outcomes, so there is a direct sense of achievement which is hard to derive from school work. I think the core problem is trying to shoe-horn everyone into the one education model whether it suits them or not, then underfunding that system to the point of collapse.
I think you're spot on. And I, for one, have great sympathy for kids who are ostracised and enter the downward spiral; I don't blame them automatically, I do think that unsupportive peers and insensitive adults contribute to their problems, if unwittingly. Of course, in the school yard there is sometimes genuine malice based on the artificial social structure students tend to impose on themselves, and this is destructive if the victims have no vision beyond their immediate situation. The emphasis placed on short term academic results by some teachers and parents does nothing to help, IMO. My theory is the reticence to understand is in part caused by the knowledge that mistreating people is often the cause of their problems, and nobody likes admitting guilt.
Explaining too much can be condescending, true, but only if too much time is spent stating the obvious. The difficult part of teaching is working out what exactly "obvious" is, though being asked direct questions does make it easier. In that regard I don't mind being given a blunt explanation, since I did ask for it;), so thank you for elucidating, it wasn't immediately obvious to me which way you were leaning. I freely admit that is a lack of comprehension on my part.
[Boring life story fragment follows, so feel free to stop reading now. I'll keep it as short as I can for the undaunted]
I certainly did know people in school who hated homework; I was one. Let me set the scene: I attended a selective high school (government run) that only admitted the top 5% of students in the state. I was already into electronics and computing (I'd been using a CP/M based Osborne 1 for a couple of years by this stage), so I had the nerd factor against me from day one. My older brother, who attended the same school, was diagnosed with a brain tumor* three months earlier and wasn't expected to see out the year, which added to my "unclean" status among my peers, led to the inevitable comparisons from my teachers (especially the deputy principal who also taught my father and uncle), and did nothing to foster a stable home environment. Electronics was offered as an elective subject, but cancelled on the first day because everyone else switched to Tech Drawing (?!?); I was given a choice of home economics or economics because the TD class was full. Computing wasn't an option because the computer lab had about 5 functioning and amazingly obsolete Apple II's, one Macintosh, and nobody to teach. The only reason I didn't go totally nuts is because I threw myself into music, so the final straw came when I was handed a directive from the New South Wales (Australia) Department of Education stating that a computer was not a musical instrument, thereby invalidating my composition major work (ironically, one of my classmates dropped out the year before to work for Fairlight, the folks who marketed the first digital sampler). So I walked out of school and into the life of a professional musician and audio engineer which made me the envy of my former class mates. That's my revenge; shallow of me, perhaps, but at least nobody died.
Now, I'm not mentioning this to elicit sympathy, just to explain that I know first hand what that kind of pressure is and what its like to be in a situation where it feels as if the entire world is stacked against you. I imagine there is even more pressure to conform now than in the 80's. Still, there is something fundamentally wrong when kids feel random violence is the only option left, though not just with the kids themselves.

Yeah, fair enough, "trend" is an exaggeration. Although I must point out, comparing it to lightning, which is (a) not a conscious act on anyone's part and (b) occurs thousands of times a day (and therefore has a greater chance of killing people) is also a bit deceptive.
The fact remains that for some reason it happens now more frequently than ten years ago. The word trend was simply a way of expressing that without delving into statistical analysis, not a suggestion that it had become fashionable.
"Have you ever asked yourself what kind of person goes around killing at random?"
I don't need to, since I was referring to the recent trend of teenagers in the US going on killing rampages simply because they have the capacity and lack a wider perspective, which strikes me as being quite an apt parallel with Anakin Skywalker. What did you think I meant?
"Hmm... that one will take you a while to figure out."
Let me guess: people who perceive being questioned as a personal insult without seeking clarification, perhaps?
So seriously, how does Anakin Skywalker relate to homework or a lack thereof? I'm actually interested in a clarification.

If they wanted to explore the crew, wouldn't an endoscope be cheaper?
Now, which would you rather flake off of your orbiter during climbout: ice, or foam?
Considering that the foam caused the last accident, the distiction is rather irrelevant.
I don't think a space program that is ten years behind its intended schedule and insanely over budget is all that impressive. Each individual launch might be spectacular, but is it really progress?
When you get a lot of smart people together, they certainly can do amazing things.
I assume Slashdot is the exception that proves the rule...
