Of course they are biased. That is his point. But our own blind spots can be revealed by studying those different perspectives.

I don't know. This seems to be the thrust of his arguments:
"By delegating information curation to multiple independent parties with demonstrated domain knowledge and critical ability, I ensure that what I read is not a mere reflection of what I believe."
Seems pretty reasonable to me.
Do you have any specific critique of "Abnormal Returns" and "The Big Picture," the curators he cites?

Codecademy.com has effective lessons on CSS. You may find it very useful.

Keeping an active inventory of your commitments (including a calendar for day to day items) allows for a couple of things:
1. Removing latent anxiety related to trying to keep track of all that needs to be done, which can in turn free one to focus on creative pursuits.
2. Making conscience decisions to defer certain projects and goals, which can also have quite a liberating effect.

Now that organizations like Khan Academy have traction and resources, I think they'll be able to bridge the gap. They'll be able to iterate as they receive feedback from the educational community.
px | 14 years ago | on: What Silicon Valley gets wrong about math education again and again
We have arrived at a point where innovation in education is just beginning. Khan Academy doesn't have all of the answers, but they have made a significant contribution to the marketplace of ideas and tools, which will continue to evolve and grow.
That type of innovation is the key to significant progress. And this sort of discussion will drive it forward.
So many people seem eager to pick the winners and losers in this space right now. It is a bit early for that.

The accuracy of these predictions is remarkable, from the anticipation of shifts in social interaction to the fragmentation of the two party system.
On this last point, is there any documentation of the role of the Internet in the development of the tea party movement?

Investors want higher margins but obviously Amazon is investing substantially in itself. So far, though, Bezos seems to be winning the tug of war. Many analysts are glad to see higher revenue and feel that Amazon is cementing its position at the top of the ecommerce world. AMZN shares are up over 5% despite the earnings miss.

I wonder if the green usernames may actually help posts by new users gain traction. I found myself more likely to take a look--curious to see what sort of submissions new users are offering.
px | 15 years ago | on: Mobile data traffic in '11 will roughly be same as total Internet traffic in '02
Link to the Cisco document that serves as the basis for this claim:
Cisco Visual Networking Index: Global Mobile Data Traffic Forecast Update, 2009-2014
http://www.cisco.com/en/US/solutions/collateral/ns341/ns525/...
edit:
One of the more interesting predictions:
"Picoprojectors are a nascent feature addition to smartphones. Although very small in number, this category promises to create higher multiples of traffic due to the high bandwidth required to project images and videos from an advanced mobile device."
I'm not so sure, though. Will picoprojectors really change consumption habits that dramatically?

This is a great post describing the mechanics of SBG. You'll get a sense of how it can work in a rigorous high school classroom.
px | 15 years ago | on: Many teachers...grading...for compliance - not for mastering course material
I'm glad the NYT is shedding light on this topic but, perhaps the most important aspect of standards based grading is almost burried in this article.
One of the basic premises of SBG is that students know exactly what knowledge and skills they have to master. They are assessed and then encouraged to address weaknesses so that they can be re-assessed. This is opposed to a "gotcha!" based assessment system.
This approach can have a profound impact on students because it encourages them to assess their own learning and take the initiative to grow and improve.

Just curious: Was this submission penalized, too? I noticed it dropped on the front page from #1 to about #25 almost instantly at around 1:50 EST.
px | 15 years ago | on: I Quit Hacker News
I welcome posts like this one. I don't agree with everything stated, and frankly it may be easy to take exception to some of the points made.
Nonetheless, I find it incredibly helpful to take a critical look at the communities I am a part of and the thinking that pervades them.

I think rudimentary is a good descriptor in this instance.
It can mean "being in the earliest stages of development" or "basic; minimal"

Just to offer another data point: I almost never watch videos but was interested enough to do so in this case. It was brief and offered enough to convince me that this might be my go-to application for managing my projects and tasks.
After playing with it for a few minutes, I am excited by its simplicity and ease of use. I've bounced around from Google docs to omni outliner to paper and pencil with just about everything in between, but I'm glad to have this tool at my disposal.

I just want to give a nod to the work and writing that Dan Meyer makes available on his blog. If you want to get a glimpse of the future of secondary math education, this is the place to look.
px | 15 years ago | on: The Fallacy Of Bimodal Returns
I appreciate Fred's candor in this post and I find his position reasonable.
This seems to be a response to PG's essay about superangels, including this section of it:
"So I think VC funds are seriously threatened by the super-angels. But one thing that may save them to some extent is the uneven distribution of startup outcomes: practically all the returns are concentrated in a few big successes. The expected value of a startup is the percentage chance it's Google. So to the extent that winning is a matter of absolute returns, the super-angels could win practically all the battles for individual startups and yet lose the war, if they merely failed to get those few big winners."
Recent blogs have taken issue with this claim, but I would like to see more throw their hats into the ring and specifically address the shifting dynamics among VCs, superangels, and founders.

No Child Left Behind aims to shed light on poor performing schools in part by requiring them to elevate graduation rates in order to meet "adequate yearly progress" goals.
Many schools are addressing the perceived urgency of these federal mandates by doing whatever they can to get the kids out the doors in four years.
px | 15 years ago | on: Google Making Extraordinary Counteroffers To Stop Flow Of Employees To Facebook
Not saying that Facebook deserves a $100b valuation, but, in all fairness, a PE ratio of 20 isn't realistic either. Facebook is perceived as the growth company that Google used to be. Investors will be willing to pay a premium for that.
