This is an important point. I've always found lecture to be a very inefficient method of teaching. Why not switch to an entirely written format? You can say a lot with diagrams and pictures. Good exercises and well explained solutions are also very important. Also if it's all text then you can easily search for keywords.


Wow, I was just thinking this morning how awesome it would be to make a desktop app that could crawl websites with jquery. And since node.js has a windows installer, it sounds like a much better solution than the C# HtmlAgilityPack I've been using.


Hm.. I tried doing this on windows but it turned out to be a lot of work to get it setup correctly. npm is hard to install on windows, and the jquery project depends on contextify, which has a binary. It does have a windows build though: https://github.com/Benvie/contextify


"Researchers at Columbia University claim the mChip has a 100 percent detection rate, although there's a four to six percent chance of getting a false positive"

That sounds like a negative result DOES mean you don't have it, but a positive result DOESNT mean you do.

Edit: I guess this is just misleading and you actually can get false negatives.


A negative result DOES mean there are not detectable levels of antibodies. However, while obviously highly linked this is NOT the same as saying you don't have it.

They're correct to say it has a 100% detection rate (assuming it does, but we have no reason to suspect otherwise), but I think this is quite misleading - it's detecting HIV-specific antibodies, not the virus itself.


Wow. Yeah, that's pretty misleading. Hope they have a big warning label to go with it.


Better false positives than false negatives. Generally, after testing positive for HIV, there are follow-up tests done to verify the result (usually with a different test from the first) and to check for t-cell count (to determine how damaged the immune system is).


Does anyone here know anything about what goes into creating a test with a 0% false negative rate? That sounds impressive (even with the noted caveats that it's detecting the antibodies and not the virus).


Making a test with 0% false negative rate is a piece of cake:

if (test_taken == true) { test_result = true; }

No negatives means no false negatives. ;)

But seriously, this is the classic trade-off between high sensitivity (no false negatives) and high specificity (essentially no false positives). Usually, the lower you set your threshold for detection the more likely you are to tell some people they have the disease when they actually don't. Where you set that bar depends on what you're trying to accomplish and forces you consider the harms associated with telling people they have disease when they don't or missing disease in someone who does.


I've had an Intel X-25M for over a year now and it's been amazing performance wise. In that same time span my 1TB data drive did die. The only problem I've had with the SSD is that it about twice a month it will randomly freeze. The hard drive light is solid on, and I have to just reset my machine. Not a big deal though because the SSD starts up so fast.


I have a similar anecdote; my 2TB western digital green drive died after a few weeks, whereas my Intel X25-M G2 is still running fine after a year and a half


If they pay you and let you buy the MacBook, it's after tax.


In Australia at least, if you pay for hardware, software or education which you use directly for work purposes or for self-education directly related to your current occupation, it is tax-deductible.


$3k is still a drop in the bucket


Great! e-mail me for my address..


I am disappointed by this: "Lesser protection of commercial speech"

I would like it to be illegal for a news organization or an advertisement to lie to or mislead the public.

If you survey 1000 doctors, and 4 say yes, you better not put "4 out of 5 doctors surveyed" in your ad.


I like how you dismiss the argument as invalid. I want to read more about this kind of reasoning, and I found this site: http://www.logicalfallacies.info/


That's a little ambitious. 3 years of medical school before they graduate high school? How about we catch up to the rest of the world first. The US K-12 education system is actually not that good. http://www.ecs.org/html/offsite.asp?document=http://nces.ed....


Yes. I was pretty astonished by this comment: "At the moment I can see 3 viable alternatives to Flash for animation: HTML, Canvas and SVG"


It says they're trying to compete with the kindle too, but I couldn't tell if the WePad can do e-ink?


I can't wait for an iPad/iPad-like device with a nice back light for reading. I can't read printed text below about 14pt comfortably, and I can't read e-Ink at any point size comrotably. I've had to resort to reading ebooks on the desktop, or laptop, where I can enlarge the font AND have the back light. I know a lot of people don't want the light for reading, but for a lot of visually impaired users, the light is essential to being able to see the text.


Since when do kindle competitors have to have e-ink?


If I was going to read an entire book on a monitor, it would have to be e-ink.


I'd read it on anything without a backlight, it doesn't necessarily have to be e-ink. (Mirasol or Pixel Qi come to mind.)


Not all people are like you.
