However I think the PPC and caldav efforts seem a bit self serving at first glance,
I have this strange feeling that most people and companies who contribute to most open source projects are a bit self serving. I'm pretty sure Linus runs Linux, for example. And Red Hat, well, they sell it!
Apple lumps tablets and smartphones together under "mobile".
Not really. The iPad has iPad specific interface elements and different human interface guidelines. Apple agrees with your breakdown, except "desktop" includes "notebook."
Absolutely, video lectures are better than nothing, and they're great when used sparingly. The problem is, a lot of people are suggesting that regular learning, classrooms and apprenticeships/internships/practicums are going to be (and should be) replaced by online videos.
What would you rather have, a vendor video or a knowledgeable representative doing an interactive learning session? You CAN learn from video lectures, it's just the most difficult way to learn.
I think what you're describing is very similar to programmed learning, which was a very popular technique in the seventies(?), but with immediate grading. It is useful, for some things, under some circumstances. It's very good for conveying facts, but not great for teaching skills or reasoning. For STEM stuff there really is nothing like a lab. See for yourself how things work and, just as importantly, that you don't know everything, with immediate feedback. Education theorists call it "guided discovery" and rate it as one of the best methods of teaching, at the opposite end of the spectrum from lecturing. For catching misunderstandings, seminars are great. Students take the assignment home, try it, and come in with their questions to work through before it's due. When I ran a seminar I used to glance at students' answers in the seminar before the due date, and again when assignments were handed in, and work through any issues right away. Most of my instructors did the same thing. I had one psych professor who did a statistical analysis of every single question on his assignments and exams to identify problematic concepts.
Good assignment questions are ones that give clearly wrong results if you do them incorrectly, but they involve that critical step of the student checking... is this a reasonable result? What do I expect? Can I do a sanity check? The habit with immediate grading is to just try things until something works. The way some people just guess then hit compile to see if they got it right.
Systems like you describe are useful, and are being built into things like electronic textbooks now, but they really don't work well for everything.
Maybe it's where I am, but most people I know have a decent set of ethics and they were instilled by their parents and teachers. As I mentioned elsewhere, we were taught about plagiarism and how to avoid it since elementary school. I work in academia so such things are taken very seriously. Several of the grad students in the lab and I have had long discussions about what's okay, what's over the line and how to tell the difference regarding plagiarism, data manipulation and statistics. Most of the plagiarism incidents I've been involved with were plausibly mistakes or ignorance, except one, where the perpetrator was caught, failed, and warned that if it ever happened again he would go through the university's process which would result in expulsion.
Absolutely. I think it's important for everyone to get a basic, broad education, but not everyone needs to do it for seventeen to twenty years. Postsecondary trade schools and apprenticeships are extremely valuable. But notice how trades are taught. Hands on, working beside an expert in the field. Essentially the opposite of the video lecture craze.
Right, because it's completely impossible for someone to find a story that's written in a particular style, which will also tend to have a similar vocabulary, and grab, reorder and glue together parts of it to make a story in a particular structure.
Oh, and "write a story" isn't an essay assignment, it's a creative writing assignment.
Yes, you do seem to be being (probably deliberately) thick.
Your brain fixes the colour cast from the ambient light, not the colour of the objects you're looking at. Does your office look like this? When you go outside does it look like this?
The corrected photos show that the landscape of Mars, at least in that location, isn't as red as photos usually show. Much of the redness comes from the light illuminating the scene - Mars' atmosphere filters out more blue light than ours does.
Perceptual colour balancing is somewhat different than absolute colour balancing. Gretag Macbeth cards, and similar white balance cards, are used specifically in photography to give photos a more natural white balance. There ARE some differences, but in most cases the adjusted image is usually closer to what you'd see than the unadjusted image.
I was replying to a commenter who said "I'd rather see what it would look like on an alien world in its native lighting conditions." Of course the white balancing is done for scientific purposes, and it's very interesting to see both. Nevertheless, the adjusted image, NOT the raw one, may well be what the commenter is looking for.
As someone who's taken, written and marked tests up to the graduate level (not in the US), I'm sorry you had such a crappy education.
You took chemistry and didn't have any labs?
How are you going to have a computer grade a complex problem like you suggest? Does the whole two-hours-of-work problem come down to one (or a few) numbers that are either right or wrong? That's a horrible way to evaluate. You'd probably be better off with multiple choice.
I've heard in the US that's true. I still find it kind of hard to believe. For what you guys spend you should be able to do a lot better. A lot of the statements like yours seem to come from commentators who haven't set foot in a school in quite a while too, so it's hard to sort out what's true and what's not.
I'm not sure what you expect from "computer generated questions." Most big multiple choice, fill in the blank, numerical answer, etc. exams are generated by computer from question banks already. Is the magic that it's on a computer screen?
The book is about the legal pitfalls of using social media to sell stuff. Potential problems of using social media to sell stuff. Selling stuff. Marketing.
I suppose it's not fully accurate to say it's about marketing, but it's certainly written in the context of marketing.
And you will get mostly people who are very good at passing your computerized tests. People who know lots of facts, but aren't very good at thinking.
One of the best courses I took in grad school was (human) Anatomy and Physiology for Engineers. The first question on the first test was along the lines of "a giraffe has a neck that is 2 m long, but with the same number of cervical vertebrae as a human. Comment on the anatomical and physiological implications." Then you wrote a long form response, actually THINKING. Neck flexibility, blood pressure, artery configuration, how giraffes drink, birth. Computers can't mark something like that, and you can't test those skills with multiple choice.
"If you adequately test, why do you also make people jump through the unnecessary steps?"
Because tests don't test various things that you want students to be able to do. Thinking, for example. Assignments also seem to be quite good at testing integrity....

Most people don't use a fraction of the VRAM they've already got.
When the pixels are smaller than you can see, even a non power of two multiple of the native resolution can be quite sharp.

That's the most fun way you can think of to get someone's DNA?
The old learning by osmosis theory (falling asleep with your head on a textbook) except with a modern trendy biology twist!
If you weren't a little late you could patent using the natural resonant vibration frequency of a quartz crystal to keep time.
How is TCP supposed to survive, as a company and... Oh, wait.

Not quite. It's more like the "special favour" you get at the airport when they decide NOT to select you for a special search.

That depends entirely on your ethics.

I've heard in the US that's true. I still find it kind of hard to believe. For what you guys spend you should be able to do a lot better. A lot of the statements like yours seem to come from commentators who haven't set foot in a school in quite a while too, so it's hard to sort out what's true and what's not.

Actually, you probably would see it more like the white balanced photo than the regular one. Your brain is very good at auto white balance.
As an example, when you're in the shade on a sunny day, does everything look blue (after the first few seconds)?
Yeah, imagine that. Maybe good education isn't as simple as making videos and posting them on the web.
