100 Essential Skills for Geeks!

As Geeks we are expected to have a certain set of skills that the majority of the population does not possess. This list is by no means complete, but I think it is a good sample of the skills required to be a true geek. I won’t pretend to have all the skills listed here. I even had to Google a few of them.

Like all good Geeks you should be able to utilize resources to accomplish any of these things. Knowing where to look for the knowledge is as good as having it so give yourself points if you are certain that you could Google the knowledge necessary for a skill.

Twitter is not for teens!

A research note written by a 15-year-old Morgan Stanley intern that described his friends' media habits has generated a flurry of interest from media executives and investors.

The Financial Times reported today that the US investment bank's European media analysts asked Matthew Robson, an intern from a London school, to write a report on teenagers' likes and dislikes.

His report, that dismissed Twitter and described online advertising as pointless, proved to be "one of the clearest and most thought-provoking insights we have seen – so we published it", said Edward Hill-Wood, head of Morgan Stanley's European media team.

"We've had dozens and dozens of fund managers, and several CEOs, e-mailing and calling all day." He said the note had generated five or six times more responses than the team's usual research.

The rapid surge of interest in social networking and messaging sites has prompted speculation that sites such as Twitter or Facebook could be taken over. But Robson's report suggested that such a move could be folly. He said teenagers were using more and more media, but they were unwilling to pay for it.

"Teenagers do not use Twitter," he wrote. "They realise that no one is viewing their profile, so their tweets are pointless."

Robson warned that traditional media – television, radio and newspapers – are losing ground as his peers prefer listening to advert-free music on websites such as Last.fm to traditional radio. Even online, teens find advertising "extremely annoying and pointless".

Time and money are instead devoted to cinema, concerts and video game consoles, which he said have emerged as a more popular choice for chatting with friends than the phone.

No teenager he knew regularly reads a newspaper since most "cannot be bothered to read pages and pages of text," preferring summaries on the internet or on television.

His report came as media moguls gathered at the Allen & Co conference in Sun Valley, Idaho. This annual event is a chance for the likes of Rupert Murdoch, Steve Jobs and Bill Gates to discuss the latest business and technology issues in a relaxed atmosphere.

When interviewed at the event, Murdoch appeared to rule out making a bid for the micro-blogging site Twitter. Asked if he was considering buying Twitter, Murdoch said, "No." Asked about selling MySpace, he replied, "Hell no."

Reclaim your hijacked search bar


The other morning, I clicked on an upgrade button for Winamp. Generally, I like the program, it seems to load faster than Media Player, and doesn't bother me too much. In the afternoon, I did a search by typing in the address bar of Firefox. Normally, this type of search brings me to the Google results of the phrase, but this time it brought me to the Winamp results of the search term. Grrrr. Winamp hijacked my search bar.

This wasn't the first time that this had happened, a few months ago, I encountered a similar phenomenon while looking for a way to convert the .3gp files that come from the audio recorder on the G1 to .mp3, .wav or just about any other format that can be used on a standard player.

As it turns out, Winamp hijacked three settings from my browser. Bad software....sit.....stay.... I successfully changed the location bar search, the search bar in the upper right, and my home page. Here's how:

Location bar:
If this is the first time you have done this, it'll be a bit more complex than normal setting changes.
Here is how to get it done:


  • Open up a new tab

  • type about:config in the location bar and press enter

  • You may see a warning message that discourages you from going further. Make your choice and live with it.

  • In the filter field, type keyword. As you type it, fewer values will be listed below

  • The one you are looking for is keyword.URL

  • The value I like is: http://www.google.com/search?ie=UTF-8&oe=UTF-8&sourceid=navclient&gfns=1&q= Which searches google and returns the result. You can also have it search through other vendors, and return different amounts of info.

  • When you close it, the settings should be changed.

  • Test it with the term of your choice to make sure it is working properly.

Search bar:
This is an easy fix. Click on the arrow to the left of the field and select the search engine you want.

Home page: This one I didn't notice until later. It's also pretty straightforward. Go to the EDIT menu, choosepreferences, then go to the MAIN section. Home page should be up in the top third of the window. Below it are a couple of buttons, including Use Current Pages. That one can be a pain, because every time you hit the Home button, it will load all the tabs you have open currently. If you are addicted to tabs, this will really send you over the edge with a zillion tabs open in no time at all. It is easier to just pick the one page that you want to be your home page, and go from there.

This process should work for Mozilla-based browsers. What are your favorite tricks with web browsers?

Bottled Water banned in Australia

waste reduction, public policy, bottled water ban, no more water bottles, australian town bans bottled water

The small Australian town of Bundanoon just set a new standard for sustainability by voting to do what no community has ever done before: ban bottled water! The measure was founded over concerns about the tremendous amount of resources used to extract, package, and transport bottled water, and it passed nearly unanimously in a town hall meeting. Will this be the beginning of a trend?

waste reduction, public policy, bottled water ban, no more water bottles, australian town bans bottled water

Although Bundanoon is a small community of about 2,500 residents, the decision to ban bottled water sets a great example for towns and cities around the world. The decision to ban bottled water began as a response to the desire of a bottling company to extract water from the town, take it to Sydney, and bring it back to the town to sell it. After the town learned of the environmental impacts of this cycle they decided to do something about it.

All the shops in the town agreed to the measure, and now instead of bottled water the town will install filtered water fountains so that people can fill their reusable bottles free of charge. The shops will sell these reusable containers to visitors coming to the town.

How to make a Cryptex?


The word cryptex is a neologism coined by the author Dan Brown for his 2003 novel The Da Vinci Code, denoting a portable vault used to hide secret messages. It is a combination of the words cryptology and codex; "an apt title for this device" since it uses "the science of cryptology to protect information written on the contained scroll or codex" (p. 199 of the novel). Brown implies that a scroll and a codex are the same thing; however a scroll is a book that is unrolled a page at a time; and a codex is a book that can be opened to any page at will, two very different things. It is claimed in the novel that the original design came from the secret diaries of Leonardo da Vinci. In reality, though there is little doubt he possessed the mechanical skill to design such a device, there is no record of him actually doing so.
But, the following video explains you how to make Cryptex:



Killer Clock Concept by Vadim Kibardin

The 'Urine' Power

Urine-powered cars, homes and personal electronic devices could be available in six months with new technology developed by scientists from Ohio University.

Using a nickel-based electrode, the scientists can create large amounts of cheap hydrogen from urine that could be burned or used in fuel cells. "One cow can provide enough energy to supply hot water for 19 houses," said Gerardine Botte, a professor at Ohio University developing the technology. "Soldiers in the field could carry their own fuel."

Pee power is based on hydrogen, the most common element in the universe but one that has resisted efforts to produce, store, transport and use economically.

Storing pure hydrogen gas requires high pressure and low temperature. Newnanomaterials with high surface areas can adsorb hydrogen, but have yet to be produced on a commercial scale.

Chemically binding hydrogen to other elements, like oxygen to create water, makes it easier to store and transport, but releasing the hydrogen when it's needed usually requires financially prohibitive amounts of electricity.

By attaching hydrogen to another element, nitrogen, Botte and her colleagues realized that they can store hydrogen without the exotic environmental conditions, and then release it with less electricity, 0.037 Volts instead of the 1.23 Volts needed for water.

One molecule of urea, a major component of urine, contains four atoms of hydrogen bonded to two atoms of nitrogen. Stick a special nickel electrode into a pool of urine, apply an electrical current, and hydrogen gas is released.

Botte's current prototype measures 3x3x1 inch and can produce up to 500 milliwatts of power. However, Botte and her colleagues are actively trying to commercialize several larger versions of the technology.

A fuel cell, urine-powered vehicle could theoretically travel 90 miles per gallon. A refrigerator-sized unit could produce one kilowatt of energy for about $5,000, although this price is a rough estimate, says Botte.

"The waste products from say a chicken farm could be used to produce the energy needed to run the farm," said John Stickney, a chemist and professor at the University of Georgia.

For livestock farmers who are required by law to pool their animals' waste, large scale prototypes could turn that urine into power within six months.

Smaller versions likely won't be available until after that, so the average consumer probably shouldn't start saving their pee just yet.

"It is not a solution for all our cars," said Stickney, "but it is the kind of process which will find many applications and will make for a greener world."

10 Stunning (And Useful) Stats About Twitter

Last month a social media analytics provider named Sysomos released a comprehensive report on Twitter usage. The problem with most analysis on Twitter, though, is that it is limited by the minimal amount of data that Twitter collects. So, to fill the gaps, most reports do things like guessing gender based on real names or pulling data from keywords in people's biographic information. This often yields some questionable results - and the Sysomos report is not immune to this (for example, they find that 65% of Twitter users are under the age of 25, but base this on only the 0.7% of users who actually disclose their age).

Looking past these small points, the report does share some fairly interesting observations and stats as well if you dig a bit deeper. Here's my read on the 10 standout conclusions that the report offers to help you (and your brand) better understand the potential uses of Twitter:

  1. 21% (One Fifth) of Twitter accounts are empty placeholders. These are the percentage of Twitter accounts that have never posted a single tweet. They may either be registered simply to hold a username for later use, or be experimental accounts started up but never used.
  2. Nearly 94% of all Twitter accounts have less than 100 followers. In a finding perhaps consistent with the newness of the tool as well as the fact that many people may currently have an account simply to start experimenting with the tool, Sysomos found the vast majority of Twitter users have an extremely low followership.
  3. March and April of 2009 were the tipping point for Twitter. During these months, Ashton Kutcher launched his quest to get to 1 million followers faster than CNN, Oprah started using Twitter, and the steady flow of new users to the site continued. For many, it offered a safer and easier way to get their feet wet with social media, 140 characters at a time.
  4. 150 followers is the magic number. In a particularly interesting data point from the survey, Sysomos found that Twitter users tended to "follow back" all their followers up until about 150 connections. Then the reciprocation rate fell off dramatically, which seems to indicate that this number may be the crossover point where people shift from using Twitter for more personal use to using it more for "lifecasting" their thoughts and actions to a community of people who they feel varying levels of connection to.
  5. A small minority creates most of the activity. A steep curve of a small minority of actively engaged content creators generating most of the activity on a site is common among social networks, but it is steeper and more pronounced on Twitter. 5% of users account for 75% of all activity, and 10% of users account for 86%. This seems to suggest that the site has managed to engage a mass audience beyond those who typically engage with social media.
  6. Half of all Twitter users are not "active." If you take a general description of being "active" on Twitter to mean that you have posted a tweet at some point in the last 7 days (1 week), then the survey learned that 50.4% of all Twitter users fit this category. If you remove the 21% from point #1, this leaves about 30% of users who have an account and have tweeted before, but happen to be inactive now.
  7. Tuesday is the most active Twitter day. One of the most useful data points from the report is that it clears up the common question of which day of the week is the best day to tweet something. Sysomos found that Tuesday stood out as the most popular day for tweets and retweets, followed by Wednesday and then Friday.
  8. APIs have been the key to Twitter's growth & utility. In terms of tools that people are using for Twitter, Sysomos found that more than half (55%) of all Twitter users use something other than Twitter.com to tweet, search and connect with others. This may, in part, be due to Twitter's notorious reputation of failing/crashing, but also is a credit to all the third party applications that have been built on top of Twitter and do their fair share to bring new users to the service.
  9. English still dominates Twitter. When exploring Russia as part of a class that I am teaching this summer at Georgetown, one of the barriers we learned about was the difficulty of fitting some Russian language words into just 140 characters. Twitter is, however, extremely English-friendly. As the Sysomos report found, the top four countries on Twitter are all English speaking (US, UK, Canada, Australia). Of these, US makes up 62% of all Twitter users, followed by UK with nearly 8% and Canada and Australia with 5.7% and 2.8% respectively. The largest non-English speaking country on Twitter? Brazil with 2%.IMB_TwitterSysomos2
  10. Twitter is being led by the social media geeks. This particular finding should likely come as no surprise, but 15% of Twitter users who follow more than 2000 people identify themselves as social media marketers. These individuals are more likely to post updates every day (sometimes more than once per day) and also use Twitter more actively for direct communication.

Bonus Geographical Stat/Quote: "The cities with the biggest Twitter populations are New York, Los Angeles, Toronto, San Francisco, and Boston. Los Angeles is the fastest growing city on the list."

Google to introduce OS!

The Google Chrome Operating System is Google's new attempt to re-think what operating systems should be.
Google Chrome OS is an open source, lightweight operating system that will initially be targeted at netbooks. Later this year we will open-source its code, and netbooks running Google Chrome OS will be available for consumers in the second half of 2010. Because Google's already talking to partners about the project, and they'll soon be working with the open source community.

Speed, simplicity and security are the key aspects of Google Chrome OS. They're designing the OS to be fast and lightweight, to start up and get you onto the web in a few seconds. The user interface is minimal to stay out of your way, and most of the user experience takes place on the web. And as we did for the Google Chrome browser, they are going back to the basics and completely redesigning the underlying security architecture of the OS so that users don't have to deal with viruses, malware and security updates. It should just work.

Google Chrome OS will run on both x86 as well as ARM chips and we are working with multiple OEMs to bring a number of netbooks to market next year. The software architecture is simple — Google Chrome running within a new windowing system on top of a Linux kernel. For application developers, the web is the platform. All web-based applications will automatically work and new applications can be written using your favorite web technologies. And of course, these apps will run not only on Google Chrome OS, but on any standards-based browser on Windows, Mac and Linux thereby giving developers the largest user base of any platform.

Google Chrome OS is a new project, separate from Android. Android was designed from the beginning to work across a variety of devices from phones to set-top boxes to netbooks. Google Chrome OS is being created for people who spend most of their time on the web, and is being designed to power computers ranging from small netbooks to full-size desktop systems. While there are areas where Google Chrome OS and Android overlap, Google still believe choice will drive innovation for the benefit of everyone, including itself.

A bag of Water can repel Flies!


We've featured many,many, many different ways to deal with mosquitoes using DIY solutions. But what about the even more common household fly? Turns out all you need to deal with that is a plastic bag or two.

Photo by brookage.

RickyC wrote in to tell us that he recently visited a lakeside restaurant and noticed some clear plastic bags filled with water hanging from the railings. When he inquired about the bags, a waiter explained that they were used to repel flies.

Question-and-answer web site The Straight Dope gives more detail on why this trick works:

Evidently, houseflies, being highly edible and defenseless, are nervous types, and don't like to sit still when they see something moving nearby, because it could be a predator. The water bag acts a bit like a lens—try it some time—in which the movements of people in the area are reflected. Even if the fly is too far from the action to see it directly, it can see a shifting of light and dark in the water bag, which it interprets as nearby movement, and it will fly away from the bag.

So, next time you have a fly problem, grab a few plastic bags, fill 'em up, and let us know how this trick works for you. Likewise, share how you keep unwanted insects out of your backyard—including whether or not you've tried this method before—in the comments.

Clock will strike 04:05:06 07/08/09 tomorrow

About an hour and 45 minutes before sunrise, the time and date will be 4 a.m. and 5 minutes and 6 seconds on July 8, 2009.

In other words, or numbers, it will be 04:05:06 07/08/09.

Although the alignment may not mean anything specific, it could be a good day to do something for yourself and others, said Betsy Carlson, a Palm Springs tarot card reader and numerology expert.

"It's a good day to make money and have good health," she said.

The sum of the time's digits equals six, if all numbers are added until there's a single figure left (4+5+6=15; 1+5=6).

Also, the numbers within the date add up to eight.

According to numerology, No. 6 represents providing a good service to humanity, while No. 8 represents making money and being healthy, Carlson said.

Let us hope, God provide everyone the best He can!

Google Apps is officially out of beta

Do you know what that means? It means that Gmail, Docs, Calendar, and Talk are losing that "beta" signage / language you've come to know and loathe. It also seems to mean that Google will be taking a much more direct and serious approach to courting businesses for its Apps suite. At first blush, it looks like the company has all but squashed the "Standard Edition" free hosted Apps package that many now use, though that isn't the case (yet). We say "all but" because while it looks like the pro bono package has been zapped out of existence by the magic raygun of capitalism, a tiny link to the service still exists on an arcane page buried deep in the casefiles of one T. Google Merryweather III. Or just Google. To be completely clear, however, regular old Gmail will still be freely available to anyone and everyone who wants a crack at it. At any rate, you'll be happy to know that the beta tag will be scuttled later today, and you can start getting righteously mad at Google for not taking care of their proper, released products immediately.

iPhone 3.0 preview & details- Coming soon!


facebook-iphone-30Facebook’s iPhone application is one of the most popular iPhone apps overall - nearly 25% of all iPhone owners use it according to Joe Hewitt, lead engineer for Facebook’s iPhone application. Today, Hewitt shared some more details on the upcoming version 3.0 of the Facebook iPhone app.

What will be coming in the new version?

1. The “new” News Feed
2. Like
3. Events (including the ability to RSVP)
4. Notes
5. Pages
6. Create new photo albums
7. Upload photos to any album
8. Zoom into photos
9. Easier photo tagging
10. Profile Pictures albums
11. A new home screen for easy access to all your stuff, search, and notifications
12. Add your favorite profiles and pages to the home screen
13. Better Notifications (they link to the comments so you can reply)
14. Quickly call or text people right from the Friends page
15. Messages you are typing will be restored if you quit or are interrupted by a phone call

The new home screen will definitely make for a friendlier user experience, especially with the addition of Events, Notes, Pages, and photo albums. The addition of the Pages feature means that brands with Facebook Pages will have increased visibility when users are on the go.

While Hewitt said he didn’t know when the app will be submitted to Apple, it is about “98% done.” However, Push Notifications, which are in high demand, will be included in Version 3.1 later this summer, Hewitt says.

Pluto is dead



This lineup shows the 12 planets that were proposed, with a wedge of the sun at far left. Ceres, Pluto, Charon and 2003 UB313 are barely visible. Now Charon will continue to be considered Pluto's satellite, and the three other worlds will be dubbed "dwarf planets" rather than full-fledged planets. The planets are drawn to scale, but without correct relative distances.

Once known as the smallest, coldest, and most distant planet from the Sun, Pluto has a dual identity, not to mention being enshrouded in controversy since its discovery in 1930. On August 24, 2006, the International Astronomical Union (IAU) formally downgraded Pluto from an official planet to a dwarf planet. According to the new rules a planet meets three criteria: it must orbit the Sun, it must be big enough for gravity to squash it into a round ball, and it must have cleared other things out of the way in its orbital neighborhood. The latter measure knocks out Pluto and 2003UB313 (Eris), which orbit among the icy wrecks of the Kuiper Belt, and Ceres, which is in the asteroid belt.

(1) A "planet" is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (c) has cleared the neighborhood around its orbit.

(2) A "dwarf planet" is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, (c) has not cleared the neighborhood around its orbit, and (d) is not a satellite.

(3) All other objects except satellites orbiting the Sun shall be referred to collectively as "Small Solar-System Bodies".

Discovered by American astronomer Clyde Tombaugh in 1930, Pluto takes 248 years to orbit the Sun. Pluto's most recent close approach to the Sun was in 1989. Between 1979 and 1999, Pluto's highly elliptical orbit brought it closer to the Sun than Neptune, providing rare opportunities to study this small, cold, distant world and its companion moon, Charon.

Most of what we know about Pluto we have learned since the late 1970s from Earth-based observations, the Infrared Astronomical Satellite (IRAS), and the Hubble Space Telescope. Many of the key questions about Pluto, Charon, and the outer fringes of our solar system await close-up observations by a robotic space flight mission.

No spacecraft have yet visited Pluto. However, NASA launched a mission called New Horizons that will explore both Pluto and the Kuiper Belt region.

The Program Accelerator

As a postgrad in the late '80s, Neil Bowers made some extra book money by acting as a helper in the computing lab. At the time, undergrads were all working on a grindingly slow VAX-11/780, and Neil and his fellow postgrads were posted there for hands-on help. This tended to be focused at the start of the year, when there were groups discovering Unix and programming for the first time.

One time, an Irish girl asked Neil for some help, saying that she couldn’t understand what was going on: she thought her program looked right, but for some reason, each time she ran it she got partial output, and varying amounts of output each time. The homework assignment she was working on involved writing a program that generated various values and wrote the results in ascii tabular form to a file.

Neil went over to her workstation and had a look at her source code. Everything looked fine. She showed him the file generated by her last run, and indeed, it looked truncated. Hmmm. "Ok," Neil asked, "can you run your program for me, so I can see what happens?".

She typed ./a.out and hit return. Her left hand darted to the keyboard and she hit Control-C. Neil was still mentally processing this when she cat'd the output, and turned to say, "See!" It did indeed contain partial output. Again.

"Um," he paused, "can you just run it again please?" Neil figured that he must have not seen right. But once again she typed ./a.out, hit return, then whap! she hit Control-C. Neil asked her why she hit Control-C every time she ran her program.

"Well," she said confidently, "I discovered that Control-C makes the % prompt come up quicker!"

PostgreSQL 8.4 is released!

The PostgreSQL Global Development Group has released version 8.4, continuing the rapid development of the world's most advanced open source database. This release contains an abundance of enhancements to make administering, querying, and programming of PostgreSQL databases easier than ever before. Our development team has spent 16 months adding over two hundred improvements to all aspects of database functionality, helping every PostgreSQL user in small or large ways.

Many of the changes in PostgreSQL 8.4 are new or improved administration and monitoring tools and commands. Each user has their own favorite features which will make day-to-day work with PostgreSQL easier and more productive for them. Among the most popular enhancements are:

  • Parallel Database Restore, speeding up recovery from backup up to 8 times
  • Per-Column Permissions, allowing more granular control of sensitive data
  • Per-database Collation Support, making PostgreSQL more useful in multi-lingual environments
  • In-place Upgrades through pg_migrator (beta), enabling upgrades from 8.3 to 8.4 without extensive downtime
  • New Query Monitoring Tools, giving administrators more insight into query activity
  • Greatly Reduced VACUUM Overhead through the Visibility Map
  • New Monitoring Tools for current queries, query load and deadlocks

Version 8.4 also makes data analysis easier through the advanced ANSI SQL2003 features of windowing functions, common table expressions and recursive queries. Enhancements to stored procedures, such as default parameters and variadic parameters, make database server programming simpler and more compact. Of course, there are also performance improvements included in this version.

Brilliant Overtime Silent Auction System at NFL


No one seems to be satisfied with the NFL’s current “Win the coin toss, get the football” overtime system. I’ve been against changing it, though, mainly because I haven’t heard any ideas that I’ve liked better. Until today, anyway.

The Fifth Down brought to my attention a beautiful system that involves strategy, rewards the boldest head coach, does not lengthen the game, keeps the basic structure of a football game intact, and, perhaps most importantly, leaves no one with any room to whine.

Here’s how it would go. The sudden death system stays in place, and the first team to score still wins the game. If that happens on the first possession, so be it. That's still the same.

However, we throw out the coin toss, and in its place, to determine which team gets the football first, we have a silent auction.

Each coach writes down the yard-line at which they’d be willing to accept the ball, and they put their bid in a sealed envelope. Both coaches hand the envelopes to an official at midfield, and the coach who’s written down the least advantageous yard-line gets the ball, at the yard-line he's written down.

So, for example, say the Steelers and Cardinals are going to overtime. Naturally, both teams want the ball first. Mike Tomlin would like the ball, but he wouldn’t mind putting the responsibility on his great defense, either, so he writes down “22 yard-line.” But Ken Whisenhunt is willing to take more of a risk, trusts his offense more, and he’s written down “11 yard-line.”

So we start overtime with the Cardinals having possession of the ball, first and 10 at their own 11. The Cards have the ball, but they’ve got quite a bit of work to do to get into field goal range. The Steelers defense has them in a tough spot, and if they do their job, the Steelers get the ball in good field position.

If Ken Whisenhunt doesn’t like that, he shouldn’t have been willing to take the ball at the 11. If Mike Tomlin doesn’t like not getting the ball first, he should have been willing to start from deeper than his own 22.

I think it’s brilliant. Perhaps some will bristle at the thought of a silent auction, a term more traditionally associated with vintage cars or estate sales, but I really think it’s perfect here. The randomness of the coin toss is eliminated, and instead, the reward goes to the coach who makes the best football decision.

The plan was dreamt up in 2003 by a fellow named Chris Quanbeck, but today’s the first I’ve heard of it. They wrote to the league about it, and NFL head of officiating Mike Pereira expressed some interest, but nothing ever came of it.

Maybe a bit more publicity will help, so this is me, doing my part. Really give it some thought, NFL. This is the best system, and I think it’s something fans would eventually grow to love.
