WiTrack: Through-Wall 3D Tracking Using Wireles Signals
"WiTrack is a device that tracks the 3D motion of a user from the radio signals reflected off her body. It works even if the person is occluded from the WiTrack device or in a different room. WiTrack does not require the user to carry any wireless device, yet its accuracy exceeds current RF localization systems, which require the user to hold a transceiver. It transmits wireless signals whose power is 100 times smaller than Wi-Fi and 1000 times smaller than cellphone transmissions."

Philip Guo - The Two Cultures of Computing
The Two Cultures originally referred to the schism between the sciences and humanities. However, I've noticed a similar schism in computing between users and programmers, which makes it hard to teach programming to beginners.
"There are now two main cultures in computing: Most computer users treat software as a tool for getting tasks done, while programmers hold conversations with their software. One big challenge when teaching programming, no matter in what language, is getting students used to a conversation-oriented programmer culture, which is very different than a tool-oriented user culture"Posted on 2013-12-27T07:47:24+0000

Essays from the funniest man in Microsoft Research - The Old New Thing - Site Home - MSDN Blogs
James Mickens has written a number of essays for ;login: magazine. The wall-of-text presentation is kind of scary, and the first time I encountered them, I skimmed the essays rather than reading them through. As a result, my reaction was, "I got tired." But if you follow the path and read the essays...
These are absolutely hilarious and worth reading.
"Interestingly, these kinds of intuitive arguments are not intuitive. A successful intuitive explanation must invoke experiences that I have in real life. I have never had a real-life experience that resembled a Byzantine fault tolerant protocol. For example, suppose that I am at work, and I want to go to lunch with some of my co-workers. Here is what that experience would look like if it resembled a Byzantine fault tolerant protocol:
JAMES: I announce my desire to go to lunch.
BRYAN: I verify that I heard that you want to go to lunch.
RICH: I also verify that I heard that you want to go to lunch.
CHRIS: YOU DO NOT WANT TO GO TO LUNCH.
JAMES: OH NO. LET ME TELL YOU AGAIN THAT I WANT TO GO TO LUNCH.
CHRIS: YOU DO NOT WANT TO GO TO LUNCH.
BRYAN: CHRIS IS FAULTY.
CHRIS: CHRIS IS NOT FAULTY.
RICH: I VERIFY THAT BRYAN SAYS THAT CHRIS IS FAULTY.
BRYAN: I VERIFY MY VERIFICATION OF MY CLAIM THAT RICH CLAIMS THAT I KNOW CHRIS.
JAMES: I AM SO HUNGRY.
CHRIS: YOU ARE NOT HUNGRY.
RICH: I DECLARE CHRIS TO BE FAULTY.
CHRIS: I DECLARE RICH TO BE FAULTY.
JAMES: I DECLARE JAMES TO BE SLIPPING INTO A DIABETIC COMA.
RICH: I have already left for the cafeteria."
Exclusive: Secret contract tied NSA and security industry pioneer
SAN FRANCISCO (Reuters) - As a key part of a campaign to embed encryption software that it could crack into widely used computer products, the U.S. National Security Agency arranged a secret $10 million
"Documents leaked by former NSA contractor Edward Snowden show that the NSA created and promulgated a flawed formula for generating random numbers to create a "back door" in encryption products, the New York Times reported in September."
"Undisclosed until now was that RSA received $10 million in a deal that set the NSA formula as the preferred, or default, method for number generation in the BSafe software, according to two sources familiar with the contract."

Why the Web Won't Be Nirvana
The truth in no online database will replace your daily newspaper, no CD-ROM can take the place of a competent teacher and no computer network will change the way government works.
This is from 1995.
"Then there's cyberbusiness. We're promised instant catalog shopping—just point and click for great deals. We'll order airline tickets over the network, make restaurant reservations and negotiate sales contracts. Stores will become obselete. So how come my local mall does more business in an afternoon than the entire Internet handles in a month? Even if there were a trustworthy way to send money over the Internet—which there isn't—the network is missing a most essential ingredient of capitalism: salespeople."
And here I sit, peacefully ordering things from Amazon so that I don't have to interact with people.Posted on 2013-12-19T03:20:56+0000

I Got Myself Arrested So I Could Look Inside the Justice System
A former prosecutor fights the law and lets it win.
"But in between the important cases, I found myself spending most of my time prosecuting people of color for things we white kids did with impunity growing up in the suburbs. As our office handed down arrest records and probation terms for riding dirt bikes in the street, cutting through a neighbor’s yard, hosting loud parties, fighting, or smoking weed – shenanigans that had rarely earned my own classmates anything more than raised eyebrows and scoldings – I often wondered if there was a side of the justice system that we never saw in the suburbs. Last year, I got myself arrested in New York City and found out."Posted on 2013-12-17T21:38:17+0000

Code rant: Are Your Programmers Working Hard, Or Are They Lazy?
When people are doing a physical task, it’s easy to assess how hard they are working. You can see the physical movement, the sweat. You also see the result of their work: the brick wall rising, the hole in the ground getting bigger. Recognising and rewarding hard work is a pretty fundamental human i...

"With a constant supply of new low-level drug sellers entering the market and ready to be exploited, drug lords can become increasingly rich without needing to distribute their wealth towards the bottom. You have an expanding mass of rank-and-file “outsiders” ready to forgo income for future wealth, and a small core of “insiders” securing incomes largely at the expense of the mass. We can call it a winner-take-all market."
Just swap "low-level drug sellers" with "fresh PhDs", and "drug lords" with "tenured faculty" and it's still true.Posted on 2013-12-01T02:21:51+0000
