The Birth of Spintronics

Interesting concept - use the spin of an atom's nucleus to store digital information, rather than the charge of an electron. This is very early research - far from a commercial product, but maybe in 20 years we'll be teaching spintronics instead of electronics.

Spintronics: A New Way To Store Digital Data:
Scientists at the University of Utah have taken an important step toward the day when digital information can be stored in the spin of an atom's nucleus, rather than as an electrical charge in a semiconductor.

The scientists' setup requires powerful magnets and can only be operated at minus 454 degrees Fahrenheit, so don't expect to see spin memory on the shelf at a computer store anytime soon. 
Christoph Boehme, an associate professor at the University of Utah, says the most important thing he and his team have done is show that it's possible to store information in spin and read it rather easily. 

Here's how they did it: First, they used a strong magnetic field to make sure all their atoms were pointing in the same direction. Then they measured which way the nucleus of an atom was spinning. Physicists don't talk about spinning clockwise or counterclockwise — they call the spins either up or down.
 

"This up and down can now represent information," says Boehme. "An up means a one, and a down means a zero."
 
Storing and manipulating these zeroes and ones — bits, in computer parlance — is at the heart of how computers work. Today, those zeroes and ones are stored using electric charge — positive or negative. In the future, things might be different. 
"Instead of electronics, people want to use spins and build spintronics, and if you do so, you need to be able to store information," says Boehme.

Data Encryption, the EFF and Code Breaking


An interesting history of DES - the Data Encryption Standard - and the efforts of the Electronic Frontier Foundation to demonstrate the inherent weaknesses in DES. At the time. DES was the federal standard for encryption of all non-classified data. It's interesting that the first crack was demonstrated as early as 1997, but a replacement - the Advanced Encryption Standard (AES) - was not approved until mid 2002.

EFF DES cracker - Wikipedia, the free encyclopedia:
In cryptography, the EFF DES cracker (nicknamed "Deep Crack") is a machine built by the Electronic Frontier Foundation (EFF) in 1998 to perform a brute force search of DES cipher's key space — that is, to decrypt an encrypted message by trying every possible key. The aim in doing this was to prove that DES's key is not long enough to be secure.

DES uses a 56-bit key, meaning that there are 256 possible keys under which a message can be encrypted. This is exactly 72,057,594,037,927,936, or approximately 72 quadrillion, possible keys. When DES was approved as a federal standard in 1976, a machine fast enough to test that many keys in a reasonable amount of time would have cost an unreasonable amount of money to build. 
The DES challenges 

Since DES was a federal standard, the US government encouraged the use of DES for all non-classified data. RSA Security wished to demonstrate that DES's key length was not enough to ensure security, so they set up the DES Challenges in 1997, offering a monetary prize. The first DES Challenge was solved in 96 days by the DESCHALL Project led by Rocke Verser in Loveland, Colorado. RSA Security set up DES Challenge II-1, which was solved by distributed.net in 41 days in January and February 1998. 

In 1998, the EFF built Deep Crack for less than $250,000.[1] In response to DES Challenge II-2, on July 17, 1998, Deep Crack decrypted a DES-encrypted message after only 56 hours of work, winning $10,000. This was the final blow to DES, against which there were already some published cryptanalytic attacks. The brute force attack showed that cracking DES was actually a very practical proposition. For well-endowed governments or corporations, building a machine like Deep Crack would be no problem. 
Six months later, in response to RSA Security's DES Challenge III, and in collaboration with distributed.net, the EFF used Deep Crack to decrypt another DES-encrypted message, winning another $10,000. This time, the operation took less than a day — 22 hours and 15 minutes. The decryption was completed on January 19, 1999. In October of that year, DES was reaffirmed as a federal standard, but this time the standard recommended Triple DES (also referred to as 3DES or TDES). 
The small key-space of DES, and relatively high computational costs of triple DES resulted in its replacement by AES as a Federal standard, effective May 26, 2002.

Things the Internet Has Really Killed

In Things the Internet Has Not Killed media writer Jeff Jarvis counters a Newsweek "slideshow alleging to list the things the internet has killed."

He then offers his own list of things the Internet has killed:

  • Government secrecy.
  • Opaque markets.
  • Central control.
  • Power elites.
  • Borders.
  • Inefficiency.
  • Ignorance.
and last but not least
  • Newsweek.

Google's Chrome OS - The Network Computer Lives Again

Call it a thin client, a cloudbook, call it whatever you want, it's still Larry Ellison's vision from 1997. The difference now?
  • more ubiquitous broadband,
  • better hardware,
  • Google's resources behind it,
  • an ad-supported model, and
  • most importantly - cloud-based apps have gained mainstream acceptance, so there's no barrier to adoption.
Google revives ‘network computer’ with dual-OS assault on MS:
In previous iterations, the vision was stymied by the lack of reliable broadband connectivity everywhere, and effectively hijacked by Microsoft. Will the Windows giant, this time around, lose out to the approach conceived by Sun, Oracle and Google – a stripped-down device with long battery life and minimal local storage or apps, connecting for its data and services to the cloud (which we used to call the server)? Google pitched its latest definition of the thin client, with the launch of Chrome OS and a next generation netbook
...
The thin client reinvented 
Back in 1997, Oracle chief Larry Ellison and Microsoft‟s Bill Gates went head-to-head on stage at a technology conference in Paris, with Ellison unleashing the new approach to computing he had cooked up with Scott McNealy, then head of Sun, and designed to kill the traditional "fat" PC with its growing software, memory and storage burden. Oracle and Sun floated the concept of thin, internet-connected clients and were joined later by Google, with its broad vision of putting every app and every piece of data and content in the cloud, to be accessed by a widening range of always-connected, slimline and mobile gadgets. 

“A PC is a ridiculous device. What the world really wants is to plug into a wall to get electronic power, and plug in to get data,” said Ellison at the time. 
Back then, the client device was called the "network computer", but it largely failed because of user wariness of letting their data and apps out of their own hands (still a major factor, which sees smartphones gaining ever larger memories), and because always-on connectivity was not available, so the concept was largely chained to the desk. Ellison said at the launch of the network computer: "We'll see hundreds of thousands of machines shipped in the first year. Very quickly, we'll see entire industry move to this model. By the year 2000, NCs will outsell personal computers." 
This prediction worked out like most such forecasts for the latest big thing in devices.

Richard Stallman On Hacking

Hacking versus cracking, from the original hacker ... On Hacking:
The hacking community developed at MIT and some other universities in the 1960s and 1970s. Hacking included a wide range of activities, from writing software, to practical jokes, to exploring the roofs and tunnels of the MIT campus. Other activities, performed far from MIT and far from computers, also fit hackers' idea of what hacking means...

It is hard to write a simple definition of something as varied as hacking, but I think what these activities have in common is playfulness, cleverness, and exploration. Thus, hacking means exploring the limits of what is possible, in a spirit of playful cleverness. Activities that display playful cleverness have "hack value".
...

Yet when I say I am a hacker, people often think I am making a naughty admission, presenting myself specifically as a security breaker. How did this confusion develop?

Around 1980, when the news media took notice of hackers, they fixated on one narrow aspect of real hacking: the security breaking which some hackers occasionally did. They ignored all the rest of hacking, and took the term to mean breaking security, no more and no less. The media have since spread that definition, disregarding our attempts to correct them. As a result, most people have a mistaken idea of what we hackers actually do and what we think.

You can help correct the misunderstanding simply by making a distinction between security breaking and hacking—by using the term 'cracking' for security breaking. The people who do it are 'crackers'. Some of them may also be hackers, just as some of them may be chess players or golfers; most of them are not.

Basic Linux Command-line Tips and Tricks - Part 2

40 Basic Linux Command-line Tips and Tricks:
21. dpkg -l : To get a list of all the installed packages.

22. Use of ‘ >‘ and ‘ >>‘ : The ‘ > ‘ symbol ( input redirector sign) can be used to add content to a file when used with the cat command. Whereas ‘ >> ‘ can be used to append to a file. If the ‘ >> ‘ symbol is not used and content is added to a file using only the ‘>’ symbol the previous content of the file is deleted and replaced with the new content. 

e.g: $ touch text (creates an empty file)
$ cat > text
This is text’s text. ( Save the changes to the file using Ctrl +D)
$cat >> text
This is a new text. (Ctrl + D)
Output of the file:
This is text’s text.
This is a new text.


23.  To count the number of users logged in : who |wc –l

24.  cat:  The cat command can be used to trickly in the following way:
- To count no. of lines from a file : cat |wc -l
- To count no. of words from a file : cat |wc -w
- To count no. of characters from a file : cat |wc –c


25.  To search a term that returns a pattern: cat |grep [pattern]

26.  The ‘tr’ command: Used to translate the characters of a file.

tr ‘a-z’ ‘A-Z’ text1 : The command for example is used to translate all the characters from lower case to upper case of the ‘text’ file and save the changes to a new file ‘text1′. 

27.  File permission using chmod: ‘chmod’ can be used directly to change the file permission of files in a simple way by giving the permission for root, user and others in a numeric form where the numeric value are as follows:

r(read-only)=>4
w(write)=>2
x(executable)=>1


e.g. chmod 754 text will change the ownership of owner to read, write and executable, that of group to read and executable and that of others to read only of the text file.

28.  more: It is a filter for paging through text one screenful at a time.

Use it with any of the commands after the pipe symbol to increase readability.

e.g. ls -ll |more

29.  cron : Daemon to execute scheduled commands. Cron enables users to schedule jobs (commands or shell scripts) to run periodically at certain times or dates.

1 * * * * echo “hi” >/dev/tty1 displays the text “hi” after every 1 minute in tty1
.—————- minute (0 – 59)
| .————- hour (0 – 23)
| | .———- day of month (1 – 31)
| | | .——- month (1 – 12) OR jan,feb,mar,apr …
| | | | .—– day of week (0 – 7) (Sunday=0 or 7) OR sun,mon,tue,wed,thu,fri,sat
* * * * * command to be executed


Source of example: Wikipedia

30.  fsck: Used for file system checking. On a non-journaling file system the fsck command can take a very long time to complete. Using it with the option -c displays a progress bar which doesn’t increase the speed but lets you know how long you still have to wait for the process to complete.

e.g. fsck -C

31.  To find the path of the command: which command

e.g. which clear

32. Setting up alias: Enables a replacement of a word with another string. It is mainly used for abbreviating a system command, or for adding default arguments to a regularly used command

e.g. alias cls=’clear’ => For buffer alias of clear

33.  The du (disk usage) command can be used with the option -h to print the space occupied in human readable form. More specifically it can be used with the summation option (-s).

e.g. du -sh /home summarizes the total disk usage by the home directory in human readable form.

34.  Two or more commands can be combined with the && operator. However the succeeding command is executed if and only if the previous one is true.

e.g. ls && date lists the contents of the directory first and then gives the system date.

35.  Surfing the net in text only mode from the terminal: elinks [URL]
e.g: elinks www.google.com
Note that the elinks package has to be installed in the system.

36.  The ps command displays a great more deal of information than the kill command does.

37.  To extract a no. of lines from a file:

e.g head -n 4 abc.c is used to extract the first 4 lines of the file abc.c
e.g tail -n 4 abc.c is used to extract the last 4 lines of the file abc.c


38.  Any changes to a file might cause loss of important data unknowingly. Hence    Linux creates a file with the same name followed by ~ (Tilde) sign without the recent changes. This comes in really handy when playing with the configuration files as some sort of a backup is created.

39.   A variable can be defined with an ‘=’ operator. Now a long block of text can be assigned to the variable and brought into use repeatedly by just typing the variable name preceded by a $ sign instead of writing the whole chunk of text again and again.

e.g ldir=/home/my/Desktop/abc
cp abcd $ldir copies the file abcd to /home/my/Desktop/abc.

40. To find all the files in your home directory modified or created today:

e.g. find ~ -type f -mtime 0

Basic Linux Command-line Tips and Tricks - Part 1

40 Basic Linux Command-line Tips and Tricks:
  1. Everything in Linux is a file including the hardware and even the directories.
  2. # : Denotes the super(root) user
  3. $ : Denotes the normal user
  4. /root: Denotes the super user’s directory
    /home: Denotes the normal user’s directory.
  5. Switching between Terminals

    Ctrl + Alt + F1-F6: Console login
    Ctrl + Alt + F7: GUI login
  6. The Magic Tab: Instead of typing the whole filename if the unique pattern for a particular file is given then the remaining characters need not be typed and can be obtained automatically using the Tab button.
  7. ~(Tilde): Denotes the current user’s home directory
  8. Ctrl + Z: To stop a command that is working interactively without terminating it.
  9. Ctrl + C: To stop a command that is not responding. (Cancellation).
  10. Ctrl + D: To send the EOF( End of File) signal to a command normally when you see ‘>’
  11. Ctrl + W: To erase the text you have entered a word at a time.
  12. Up arrow key: To redisplay the last executed command. The Down arrow key can be used to print the next command used after using the Up arrow key previously.
  13. The history command can be cleared using a simple option –c (clear).
  14. cd :   The cd command can be used trickily in the following ways:

    cd : To switch to the home user
    cd * : To change directory to the first file in the directory (only if the first file is a directory)
    cd .. : To move back a folder
    cd - : To return to the last directory you were in
  15. Files starting with a dot (.) are a hidden file.
  16. To view hidden files: ls -a
  17. ls: The ls command can be use trickily in the following ways:

    ls -lR : To view a long list of all the files (which includes directories) and their subdirectories recursively .

    ls *.* : To view a list of all the files with extensions only.
  18. ls -ll: Gives a long list in the following format

    drwxr-xr-x 2 root root 4096 2010-04-29 05:17 bin where

    drwxr-xr-x : permission where d stands for directory, rwx stands for owner privilege, r-x stands for the group privilege and r-x stands for others permission respectively.

    Here r stands for read, w for write and x for executable.
    2=> link count
    root=> owner
    root=> group
    4096=> directory size
    2010-04-29=> date of creation
    05:17=> time of creation
    bin=> directory file(in blue)

    The color code of the files is as follows:
    Blue: Directory file
    White: Normal file
    Green: Executable file
    Yellow: Device file
    Magenta: Picture file
    Cyan: link file
    Red: Compressed file

    File Symbol
    -(Hyphen) : Normal file
    d=directory
    l=link file
    b=Block device file
    c=character device file
  19. Using the rm command: When used without any option the rm command deletes the file or directory ( option -rf) without any warning. A simple mistake like rm / somedir instead of rm /somedir can cause major chaos and delete the entire content of the /(root) directory. Hence it is always advisable to use rm command with the -i(which prompts before removal) option. Also there is no undelete option in Linux.
  20. Copying hidden files: cp .* (copies hidden files only to a new destination)

    Tom Friedman Discussing The World is Flat

    Great resource from MIT's OpenCourseWare project. You might not be able to get Tom Friedman to come to your campus, but you can still have him speak to your students.



    The World is Flat 3.0 | MIT World:
    Elaborating on his World is Flat thesis, Friedman describes how this new global order puts creative, entrepreneurial individuals in the driver’s seat, and poses distinct new challenges and opportunities. 
    The digital platform that connects Bangalore, Boston and Beijing enables users from any of these places to “plug, play, compete, connect and collaborate,” and is changing everything, says Friedman. He lists some basics to keep in mind: Whatever can be done, will be done, “and the only question left is will it be done by you or to you.”

    Gingerbread and the Archos Tablet

    In response to Samsung Galaxy Tab Review, reader WDOS-FM comments:
    Very true. I have some friends that have used it and don't really like it. iPad seems to be the winner on the market right now. I feel however, that Archos tablets will do really well once Android Gingerbread is released fully as it will have tablet support. 
    Great comment! It's true that the current version of Android is not optimized for larger displays, such as a tablet. Even Google is cautioning tablet manufacturers to wait until Gingerbread. The Archos tablet does look promising.

    Samsung Galaxy Tab Review

    Interesting review from Electronista.




    Fairly favorable review overall, but strange dichotomy: Pro - Flash as a option; Con - Flash as an option. They give it 3 and a half out of 5 stars, but based on the review I don't think they're recommending anyone buy it.

    With a retail price of $599 off-contract, the Galaxy Tab is $30 less than the comparable 16GB iPad, but we're not sure it's automatically a bargain. We’re really disappointed with the web browsing, Flash and video chat performance of the Tab and we’re still a little perplexed with the form factor of the device, especially since you pay only slightly less for what amounts to much less screen area. To really steal market share from Apple, the Galaxy Tab would need to have a larger screen, more dedicated apps, and keep its dual-camera setup all while maintaining or dropping its price point.

    The Outlook for IT Jobs

    Scary headline! I've talked to experienced IT workers, whose companies are having hiring freeze and multiple rounds of layoffs. I'm hoping that this is just a result of the recent economic downturn and not a longer more systemic trend. In the past, I've encouraged students to model themselves - namely their education, and career as the letter 'T.' They should have a breadth of knowledge within their discipline (e.g. multiple operating systems, clients, servers, switches, routers, wired, wireless, security, etc.) and select one key area to focus on where they develop a great depth of understanding.  More recently, I've been advising students that they should look like the letter 'm' - the same breadth of knowledge, but now begin to cultivate a depth of knowledge in three distinct areas. It's more work for the students, but in the end, I think this will make them more marketable and allow for a more sustained career path.

    m versus t.png

    Why IT Jobs Are Never Coming Back:
    The combination of more automation, increased offshoring, and better global IT infrastructure has taken its toll on the U.S. IT profession, resulting in a net loss of 1.5 million corporate IT jobs over the last decade, according to recent research from IT consultancy and benchmarking provider The Hackett Group. 
    The barely bright side for the American IT worker is that the total number of annual job losses will diminish slightly in the coming years, down from a high of 311,000 last year to around 115,000 a year through 2014, according to Hackett which based its research on internal IT benchmarking data and publicly available labor numbers. The really bad news? It's unlikely that IT will contribute to new job creation in the foreseeable future. "To succeed over the next five years, companies need to understand how to reposition existing talent; jettison or rationalize current jobs that have no place in the leveraged organization; and source, develop and retain still others to fill the need for new skills, both offshore and in retained onshore staff,"

    Teaching Our Students Entrepreneurship

    More important now than ever ...
    Young Entrepreneurs Create Their Own Jobs:
    THE lesson may be that entrepreneurship can be a viable career path, not a renegade choice — especially since the promise of “Go to college, get good grades and then get a job,” isn’t working the way it once did. The new reality has forced a whole generation to redefine what a stable job is. 

    “I’ve seen all these people go to Wall Street, and those were supposed to be the good jobs. Now they are out of work,” says Windsor Hanger, 22, who turned down a marketing position at Bloomingdale’s to work on HerCampus.com, an online magazine. “It’s not a pure dichotomy anymore that entrepreneurship is risky and other jobs are safe, so why not do what I love?” 

    Mr. Gerber argues that the tools to become an entrepreneur are more accessible than they’ve ever been. Thanks to the Internet, there are fewer upfront costs. A business owner can build a Web site, host conference calls, create slide presentations online through a browser, and host live meetings and Web seminars — all on a shoestring.

    Chained to the Past: Collaboration and the Distributed Workforce

    Some interesting data from a Forrester research study.
    forrester1.png
    Pretty scary that in 2010 the top 2 "collaboration technologies" that businesses are looking to adopt are Email and Email/calendaring for mobile devices. The study was commissioned by Citrix Online, so I suppose they were hoping to see web and video conferencing at the top of the list. Alternatively, one could argue this demonstrates that there is room for growth.
    forrester2.png
    Sadly, in spite of the emergence of social media, web conferencing, and robust collaboration tools, workers are still chained to 20th century standbys - Email, Phone, and Face-to-face. I think people use what they are comfortable with and what has worked in the past - most see abadoning these for "new" technologies as too risky.

    Making Collaboration Work for the 21st Century's Distributed Workforce:
    Last month we published an infographic on the international language of business based on a study that Citrix Online commissioned from Forrester Consulting. Today we're happy to launch the results of that study. The study yielded surprising findings related to generational and cultural working behaviors that impact how businesses communicate and collaborate in an increasingly dispersed workplace, and the implications for the future competitiveness of SMBs.

    Key Findings
    The study asked information workers of all ages in the United States, United Kingdom, France, Germany and Australia about their business communication habits. 
    Gen Y does not have the monopoly on technology use and social tools during the work day. Meanwhile, the older generation is getting with the program.
    • Gen Y is least likely to share information via text message (26%, compared to 47% of those aged 55+), and least likely to use video conferencing, video chat and web conferencing tools.
    • Gen Y uses social networking the least frequently (40% of Gen Y workers who use social media do so daily, compared to 50% of those aged 55+).
    • Older Boomers (55+) have increased their business use of social media 79% in the past year.
    The younger you are, the less you value meetings - and pay attention.
    • Gen Y is least likely to think meetings are efficient. Only 29% of Gen Y workers think meetings used to decide on a course of action are very efficient, compared to 45% of Older Boomers.
    • Gen Y is least likely to pay attention in meetings and barely half (51%) believe it's very important to do so in meetings to decide a course of action.
    Americans have more meetings - and pay more attention.
    • 90% meet in person to communicate and build relationships, more than any other nationality.
    • Of those, 51% meet daily, compared to a mere 31% of French.
    • 75% of Americans believe it's very important to pay attention in meetings to decide on a course of action, compared to 50% of the French.
    The in-person meeting is alive and well, but not necessarily effective.
    • 84% of all respondents have in-person meetings, but meetings often don't achieve their goals.
    • Only 45% are very satisfied that planning meetings achieve the task in hand, and only 30% believe such meetings to be very efficient.
    • Across all categories of meetings for designated tasks (e.g. review of documents, plan projects or initiatives, decision on a course of action), less than half of respondents believe those meetings are very efficient.
    In an era of multitasking, it's still considered rude in a meeting.
    • 83% believe that side conversations are unacceptable during a meeting, and 77% frown on those doing other work on a computer or smartphone.

    Final Nail in Microsoft Kin's Coffin

    Kin Studio Closing On January 31st: Kin Will Really Die Now:

    We thought it was weird when Microsoft killed Kin only to have Verizon oddly resurrect it. It doesn't matter anymore because on January 31, 2011, Microsoft's Kin Studio, the cloud that the Kin relies on to work, will close. Verizon will even give you a free 3G phone to replace your Kin.

    FCC - 68 Percent of US Broadband Connections Aren't Really Broadband

    fcc report1.png

    fcc report2.png

    FCC report finds 68 percent of US broadband connections aren't really broadband:

    As the FCC itself has made abundantly clear, the definition of "broadband" is an ever-changing one, and its latest report has now revealed just how hard it is for the US to keep up with those changes. According to the report, a full 68 percent of "broadband" connections in the US can't really be considered broadband, as they fall below the agency's most recent minimum requirement of 4 Mbps downstream and 1 Mbps upstream. Also notable, but somewhat buried in the report, are the FCC's findings on mobile broadband use. The agency found that mobile wireless service subscribers with mobile devices and "data plans for full internet access" grew a hefty 48% to 52 million in the second half of 2009, and that when you consider all connections over 200 kbps, mobile wireless is actually the leading technology at 39.4 percent, ahead of cable modems and ADSL at 32.4 and 23.3 percent, respectively. When it comes to connections over 3 Mbps, however, cable modems account for a huge 70 percent share.

    The Death of Mass Transportation - Railways

    This photo from Thomas Hawk makes me think of the rail system and mass transportation infrastructure we used to have in this country. Imagine how much better off we'd be today if we had a vibrant, national rail system. I know there's Amtrak, but Amtrak pales in comparison to the mass transportation systems in parts of Europe and Asia.

    Twitter In 5 Minutes A Day

    Some great Twitter tips from self-described solopreneur Justin Vincent. Click the link to read the entire post.

    How To Make Twitter Work For You In 5 Minutes A Day:
    When I first started hearing about Twitter over a year ago I wasn’t sure what all the fuss was about. Now, a year later, I understand exactly what all the fuss is about!

    Twitter is a genuinely awesome tool to help you grow your business and your personal network. By participating in Twitter for 5 minutes a day I have seen the following benefits within one year:


    • I found an awesome business partner who is co-founder of my new start-up
    • I raised awareness of my start-up Pluggio and made $12,000 revenue as a result
    • I asked many questions about things I was struggling with and instantly got excellent answers
    • I asked if anyone needed a contractor with my skill-set and instantly got a job
    • I drove hundreds of users to the weekly tech podcast that I co-host (TechZing)

    The Story of the Brooklyn Bridge

    Great piece on the history of the Brooklyn Bridge and the Roebling family.
    The Story of the Brooklyn Bridge: A Roebling Family Production:
    The Brooklyn Bridge is one of the most famous landmarks in the Five Boroughs of New York City. For over a hundred years, it has been the main crossing-point of the East River for New Yorkers and Brooklynites, heading to each other’s part of town for work and play. Yet, in the scope of history, the Brooklyn bridge hasn’t been around that long at all. When its construction was finished in 1883, it was the biggest suspension-bridge in the United States, but the story behind its construction is one that is even more amazing that the structure that resulted from it. It took fourteen years, hundreds of men, cost one man his life, another man his mobility and thrust an unprepared housewife into the harrowing man’s world of engineering, construction and design, a world which she knew nothing about. This is the story of the Brooklyn Bridge.
    ...
    The toll for crossing the bridge on the Opening Day was one penny. This was increased to three pennies for every day thereafter. 150,300 people walked across Brooklyn Bridge on its first day, and 1,800 vehicles drove across it! That’s a phenomenal amount, when you consider that the bridge was only opened to traffic at 5:00pm that afternoon!

    The Lightfoil




    Optical Wing Generates Lift from Light

    Physicists in the United States have demonstrated the optical analogue of an aerofoil--a "lightfoil" that generates lift when passing through laser light.

    The demonstration, which comes more than a century after the development of the first airplanes, suggests that lightfoils could one day be used to maneuver objects in the vacuum of outer space using only the Sun's rays. "It's almost like the first stages of what the Wright brothers did," says lead author Grover Swartzlander, a physicist at the Rochester Institute of Technology, New York, whose study appeared December 5 in Nature Photonics. (Scientific American is part of Nature Publishing Group.)

    The principle of a lightfoil is similar to that of an aerofoil: both require the pressure to be greater on one side than the other, which generates a force, or lift, in that direction. With an aerofoil, the pressure difference arises because air must pass faster over the longer, curved side to rejoin the air passing underneath.

    With the lightfoil, the pressure comes from light rather than air. Such "radiation pressure" was theorized by physicists James Clerk Maxwell and Adolfo Bartoli in the late 19th century, and exists because photons impart momentum to an object when they reflect off or pass through it. It is the reason, for example, that comet tails always point away from the Sun--the Sun's rays push them that way.

    How We Consume 34 Gigbytes of Data - a Day

    This makes for an interesting class assignment - define the same 6 categories (Radio, TV, Computer, Reading, Phone, Other) and have students track a typical days worth of usage.
    America Hungry, Need Data:
    According to a new study by the University of California, San Diego, from 1980 through 2008 the total number of bytes bitten by Americans has upped by 6% per year and now stands at an incredibly huge sounding 3.6 zettabytes. (Or one billion trillion bytes, if that's easier to imagine.)
    ...

    Here we break down what 3.6 zettabytes--or 34 gigabytes a day--means in terms of daily consumption.

    The Rise Of The Gentleman Hacker

    The Rise Of The Gentleman Hacker:
    Michael Arrington ran into
    two entrepreneurs that have made a ton of money by selling their companies in the last couple of years. They’re both working on a slew of new projects, and the way they’re doing it is fascinating.

    What does a person do after becoming fabulously wealthy?
    ...
    But I’m hearing more and more about people who are simply setting up an office somewhere close to their multi-million dollar home in Silicon Valley or San Francisco, hiring a handful of hackers, and just building stuff to see what happens.

    In many ways it’s analogous to the gentleman farmer – someone who farms, sorta, but doesn’t really worry about profit because they are independently wealthy.
    I think it's more about just building stuff that interests them and if anything comes of it great, if not - no biggie.

    Bring Back Unlimited Data

    4G data.png
    Using up your monthly 5 GB data allotment in less than a day - wow!
    Verizon LTE Blows Through Monthly Data Cap in 32 Minutes:
    Verizon's new 4G LTE network is so fast that you can use up your entire 5GB, $50 monthly allotment in 32 minutes. 
    I'm in the middle of testing Verizon's new LTE network, and the 2010-era speeds are soured by the 2005-era thinking on data plans. Verizon has priced LTE pretty much like 3G to encourage data sipping, not guzzling. As soon as you start using the latest high-bandwidth Internet services, your whole month's allotment can evaporate within a day. 
    My tests maxed out at an impressive 21Mbps. If you were downloading 5GB at that speed, it would only take you 32 minutes. Since the LTE network currently has almost nobody on it, I got average speeds around 15Mbps; Verizon estimates you'll be able to get around 8.5Mbps with a loaded network. But very few applications actually use those speeds consistently, so I also checked out some more common uses. 
    Downloading some files via BitTorrent, I registered 5.6Mbps, which could use up the cap in about two hours. Standard-definition Netflix video is kinder to your data cap; according to Netflix, they encode at 1500 kbps, so it'll take you 7.4 hours to burn through your monthly allotment. That's fewer than four movies.

    More on the Kindle

    David Welton just bought a Kindle. Here are his thoughts.

    The good:
    I like it a lot.  I was worried that I would not actually enjoy reading with it, or that it would be significantly inferior to real books.  However, I do enjoy reading with it, and I think they have achieved their aim of making it so that it 'just disappears' like a good book does.  It's a very small and light device, even with the leather cover I got for it (always best with a small child in the house), so it's in no way heavy or uncomfortable.  It's relatively more expensive and fragile than a copy of The Economist or a paperback, so I don't sling it around quite so casually, and do try and remember to keep it out of reach of said small child, which makes it a little less worry-free than an actual book.  On the other hand, it's much cheaper than an ipad or samsung galaxy or something like that, so it's not the end of the world if something happens to it, although it would be unfortunate to be without reading material for the time it took to replace it!
    ...
    there are quite a few books available for it for *free* because they're old and out of copyright.  Stuff you might get for 99 cents at a used book store as a paperback, but it's pretty cool to be able to just zip it right to the device, for nothing at all.

    The bad:
    The selection of material available for it is ok, but I'm just a bit disappointed - I thought offhand there were more books than there are.  I regularly bump into things I might consider getting if they were available for it, but are not.
    ...
    I find it somehow a bit monotonous to read everything in the same form factor and with the same fonts.  It takes something away from the character of a book, especially a well-done hardback.  Of course, what counts is the content, but the presentation counts for something too, I think.
    ...
    it does have a browser, however, the screen refresh is so slow that I'd only really consider using it for reading web pages - wikipedia, say, rather than doing much with it.

    Why the Kindle Is Losing Me

    Strangely schizophrenic article Why the Kindle Is Losing Me from Sarah Lacy. She begins with a glowing tribute to the Kindle and its' virtues.
    I really loved my Kindle when I first got it. I love writing books, and I’m for anything that helps people consume and purchase more of them– I don’t care if I make a fraction of the royalties off electronic sales. 

    I was especially struck by how much I wished I’d had a Kindle in college. As a literature major I read about five books a week, not to mention all the textbook reading for other courses. There were so many great touches in the UI that elevated the experience from just putting a book on a screen. There’s the Kindle store and its friction-free, one-click purchases from anywhere, say, a cafe the night before the exam when you still haven’t bought the book. There’s the freedom from lugging around a heavy backpack of books. And there are so many features that are designed specifically for collegiate reading like the ability to easily highlight, annotate, store those annotations in a specific file, and be able to easily search around within the book and find certain quotes or passages. I thought, this isn’t a beautiful piece of hardware, but it is clearly designed by someone who knows high-volume readers.

    The I heart Kindle quickly deteriorates into diatribe on the lack of page numbers and the resulting difficulty in creating footnotes for the book she is working on.
    So how the hell is it possible that the Kindle doesn’t have a feature as obvious as page numbers? You know what happens when you don’t have page numbers? You can’t do a basic footnote for anything you’ve read. Yeah, that’s going to be a slight problem for the college market.
    ...
    footnotes from a Kindle edition have been a nightmare. I have had to either use Google books to find page numbers or, worse, repurchase them in hard cover just to do footnotes.
    ...
    Amazon needs to fix this now.

    IT Salaries

    Read more @ IT Salary: National Averages for 45 IT Jobs:
    The following list of IT salaries illustrates some overall trends. An IT project manager with more than 7 years of experience earns (on average) in the $100k range, while that same pro with just 2-4 years under their belt pulls in about $70k. An IT staffer who works for a big outfit makes more than his small business counterpart (for instance, an Enterprise Infrastructure Manager makes $108k). IT security professionals are perennially in demand, so the $102k annual salary for IS Security Managers is no surprise. And thought leaders, the people who actually envision IT systems, do quite well, hence the $108k for Systems Architects. 
    As for developers, their salary levels range wildly, from a newbie client server programmer, $54k, to an advanced Operating Systems Programmer, $105k. (Naturally location makes a big difference as well, with developers in big cities making far more).

    How to Destroy Your Corporate Brand

    Our college switched to Dell a few years ago. We've a ton of problems with bad hard drives in laptops. Hard drive issues in desktops too, but not nearly as frequent.

    How a capacitor popped Dell's reputation:
    From 2003 to 2005 Dell shipped 11.8 million PCs with a known defect but chose not to fully disclose the situation to all of its customers. The inside details of its management decisions, unsealed after settlement of a lawsuit, and the consequences of its customer service blunders, appeared side-by-side in two New York Times stories recently. 
    Dell finally settled the lawsuit in September and its enterprise business has recovered. But the consumer side is struggling, in part because of what one analyst called "lingering" negative perceptions of its customer service.
    It seems Dell mishandled the situation at virtually every opportunity.
    • misread the severity of the problem,
    • slow to act,
    • focused on minimizing financial damage, rather than brand damage,
    • treated large customers better than average consumers.

    At first Dell underestimated the scope of the problem, which it tracked back to inferior capacitors that could lead to a catastrophic failure of PC motherboards. Dell grossly underestimated failure rates. Early on it expected rates as high as 12%, which is bad enough. But even as it revised estimated failure rates drastically upward, Dell continued to ship PCs with the defective capacitors as it struggled to identify the components and remove them from its supply chain. 
    Dell kept production moving and revenues coming in in the short term, but it also dramatically increased its liability and damaged the company's reputation for quality. 
    Failure to be proactive
    Rather than be proactive, Dell's strategy was to "fix on fail." Even as some frustrated customers reported failure after failure and rumors began to circulate, for the vast majority of customers Dell did not choose to proactively replace or repair machines known to have the defective component. 
    As the scope of the crisis became clear, with at least one volume customer reporting failure rates exceeding 20 percent, and with its its own estimates projecting potential failure rates of of 45 to 97 percent, management made a series of decisions that appear to have been carefully calibrated to minimize Dell's financial exposure and avoid a full recall. 
    The PC maker began proactively replacing PCs with the defect, but only for its large customers that made volume purchases, and then only after the customer experienced a failure rate exceeding 5%. It also triaged customers into three categories: Those who might move their accounts over the issue, those who might cut back on purchases over the problems - and everyone else.

    Predictions for RIM/Blackberry

    This is premature. RIM still has a huge footprint in the enterprise, but they're quickly losing market and mind-share to both Android and iOS devices. They need their tablet - the playbook - to be a winner, and they need to come up with a viable challenge to the Android/iOS ecosystems - fast!

    The Death of RIM

    If one function devices could continue to triumph, the iPod would not be supplanted by the iPhone.

    A friend just asked me if I was on BBM. That’s BlackBerry Messenger for the uninitiated. And many may never be initiated, because BlackBerry is so 2001. Or 5. Or maybe even 6 or 7, but certainly not 11.

    BlackBerries do one thing incredibly well, process e-mail.

    And that’s it.

    Is This Beginning of the End of Net Neutrality?

    I hope not.
    OpenDNS was founded in 2006 and quickly made a lot of fans around here due to their fast, reliable DNS servers and DNS services. It has been a profitable business; in 2008 it was estimated that OpenDNS generates a whopping $20,000 per day off of their DNS redirection relationship with Yahoo. Every DNS outage over the last four years effectively acted as an advertisement for OpenDNS, and the company has grown substantially -- now serving roughly 20 million users.

    As ISPs slowly discovered that OpenDNS was eroding a possible revenue stream (redirection portal ads), many ISPs rushed to offer DNS redirection systems of their own -- with various degrees of success.
    ...

    Some ISPs may now begin taking a harder stance, if this Washington Post interview with OpenDNS founder David Ulevitch is any indication. According to Ulevitch, OpenDNS is being blocked by Verizon Wireless already, and Ulevitch is concerned that a growing number of landline broadband ISPs are going to begin doing this as well to protect their coffers:

    They do not want to see DNS traffic, queries and data streams leaving them. In the way we have monetized domain name services, they want to do what we do. But they aren't an opt-in service like we are, and they can also block us, which is what we are concerned about. And they try to block us in crafty ways. There was a report of an ISP working group whose members said that for "security" reasons, they should block alternative DNS services.

    This raises an interesting neutrality situation we'll need to keep an eye on, given that ISPs who block OpenDNS will certainly try to insist it's about security, not money (and will certainly have cherry picked data pie charts to "prove" it). Granted, OpenDNS could just do what companies like Skype and Google have been doing recently -- and throw their neutrality principles out the window in exchange for large bags of money and exclusive service partnerships.

    Innovative Use of the iPad

    21st century food bank?

    iPads Help FareShare Rescue Good Food from Landfill

    "Approximately 28,000 supermarkets worth of food goes to landfill every year in Victoria," suggests FareShare CEO Marcus Godinho. FareShare is a food rescue service in Melbourne, Australia, who were a joint winners of the 2010 Premier's Sustainability Awards. So far this year they've saved 468 tonnes of food that would've otherwise been sent to landfill. Then 3,000 volunteers have cooked 1,114,461 meals for the needy, and doing so FareShare has supported 130 charities.

    As those impressive figures suggest, this is no ordinary do-gooder group, but a well-oiled, switched-on, dynamic organisation. Their recent adoption of Apple iPads to streamline operations further distances them from the quaint, fuddy duffy soup kitchens of old.

    Harnessing Technology

    Using an iPad application developed by staff and volunteers, IT Wire reports that FareShare is now able to alert the kitchen's chefs of what food ingredients have been collected in real time, increasing their capacity to prepare free nutritious meals for charities. IT Wire notes the app also reduces the charity's paper trail, improves monitoring and reporting, and increases efficiency.
