Computer Activities with a Purpose

If you use the Internet at all, odds are you've been asked to complete a "CAPTCHA". These are the distorted "words" that a human is able to read and type but are supposed to stump computers. Captcha's were invented in 2000 by Luis Von Ahn, Manual Blum, and others at Carnegie Mellon University and stands for "Completely Automated Public Turing test to tell Computers and Humans Apart".

In a talk at Ted.com, Luis Von Ahn said he felt guilty about Captchas and the time lost in filling them out. They are needed to prevent computer spamming but could there be a better use of people's time? So Von Ahn created reCAPTCHA which looks the same but instead of random, distorted words, reCAPTCHA uses words that stumped OCR (optical characters recognition) while digitizing books in the public domain for the Gutenberg project. Each reCAPTCHA is shown to hundreds(?) of people and the majority vote is used to update the word in the digital copy of the book. With 100 million reCAPTCHAs every day, the service has been able to digitize thousands of books.

Von Ahn's PhD thesis was devoted to Games With A Purpose, or GWAPs. Can people have fun on the Internet and accomplish something useful at the same time? One example is the ESP game. Two random people are show the same photo via the Internet. They receive points for how closely their description of the photo matches. The best matching descriptions are saved by Google to help identify photos for future image searches.

Von Ahn's newest project is http://www.duolingo.com/. His team thought, why not learn a language and help translate the Internet at the same time? The online lessons in English, Spanish, German, and French are free. My wife & I have learnt a lot. With duoLingo you earn points by translating actual websites in foreign languages and rating the translations of others. Give it a try!

Manual Backup for Cars?

When technology fails, it's always nice to have a low tech backup. For many years my wife & I resisted buying cars with electric windows and door locks. Suppose the car goes in the water and the electrical system shorts out. How will you escape the car? We had one car dealer argue, "it's free", but it was not a matter of cost, we WANTED the old-fashioned locks and windows. Also today it's impossible to but a new car without power windows.

When my father rented a car recently, he & I were stumped. How do you turn it on? There was no keyhole for ignition; just a "Start" button. We pressed the button and nothing happens. We later learned that the start button only works while the brake pedal is pressed.

Another "power" feature on new cars is keyless entry. But what if you press your "key" and nothing happens?
This is the bane of drivers in the Bermuda Triangle of lost cars in Yonkers, NY.  According to the Consumerist,
"A nearby funeral home owner says he's had constant complaints about people getting locked out of their cars, including his brother who had to get his car towed away."
A "radio-frequency specialist says there's likely a malfunctioning device in the area that's overpowering all the other quick signal bursts from remotes with its constant strong signal. He says drivers who experience such a thing should bring their keyless remotes as closely to their cars' antenna as they can, to minimize possible interference.
Local employees have learned to park far away or else PUSH their car out of the no-key zone.

New First Aid Smartphone app



Last month the American Red Cross launched its official first aid app, putting free and simple lifesaving information right in the hands of smart phone users.  It gives instant access to information on how to handle the most common first aid situations, and includes videos and interactive quizzes. Users who take quizzes can earn badges they can share with friends through social media to show off their lifesaving knowledge.

“The American Red Cross First Aid app is a free and easy way to get lifesaving first aid instruction and disaster preparedness information anytime, anywhere,” said Red Cross Scientific Advisory Council chair Dr. David Markenson. “Everyone should load this onto their smart phone as an important first step in learning what to do for medical emergencies and in creating a family preparedness plan.”

App features include:
  • Simple step-by-step instructions for everyday first aid scenarios;
  • Prioritized steps to take during an emergency, with 9-1-1 call button;
  • Sharable badges to be unlocked through interactive quizzes;
  • Videos and animations to make learning first aid fun and easy;
  • Safety and preparedness tips for a range of conditions including severe winter weather, hurricanes, earthquakes and tornadoes;
  • Preloaded content that gives instant access to all safety information at any time.
Find the app in the Apple App Store and the Google Play Store for Android by searching for American Red Cross

The webpage from beyond the grave

I've heard stories of high end cemeteries like Beverly Hills whereby you can embed a computer screen in your headstone that plays a video of you upon request. Sounds like science fiction but very doable (the hardest part would be power and weather proofing).

A much simpler solution of leaving a message that survives you is Facebook and other social networking sites where your personal page might remain long after your death. For some this is comforting, for others disturbing. Family members will sometimes ask Facebook for the password of a deceased loved-one so they can update the page with a death notice. Facebook does not have to comply with this request. Ditto for personal websites hosted by Google. There are few laws about passwords and death.

Our helpful government at USA.gov offers some suggestions: add a social media section to your will  (you do have a will, right?)
  • appoint someone you trust as an online executor
  • State how you would like your profiles to be handled. You may want to completely cancel your profile or keep it up for friends and family to visit. Some sites allow users to create a memorial profile where other users can still see your profile but can’t post anything new.
  • Give the social media executor a document that lists all the websites where you have a profile, along with your usernames and passwords.
  • Stipulate in your will that the online executor should have a copy of your death certificate. The online executor may need this as proof in order for websites to take any actions on your behalf.

Should I Eject USB drives before Removing Them?

LifeHacker.com examines a question that has long been in the back of my mind, "Do I Really Need to Eject USB Drives Before Removing Them"? USB Drives, also called thumb drives, flash drives, etc, are inserted into one of the USB ports and can be just as easily removed at anytime. But you may have noticed an Eject Option and the words, it is now safe to remove the media, after Ejecting. What's unsafe about pulling a drive out?
"Obviously, yanking out a drive while it's being written to could corrupt the data. However, even if the drive isn't actively being written to, you could still corrupt the data. By default, most operating systems use what's called write caching to get better performance out of your computer ... — the OS waits to [write files] until it has a number of requests to fulfill, and then it fulfills them all at once ... When you hit that eject button, it tells your OS to flush the cache—that is, make sure all pending actions have been performed—so you can safely unplug the drive without any data corruption."
Bottom Line

Now MS Windows is a bit odd when it comes to USB drives. Most of the time it recognizes the drive as "removable", disabling write caching, making it safe to remove the drive without ejecting. But it's not a sure thing and you can not ALWAYS count on this for every USB drive manufactured. So it's a best practice to always click on Eject first, wait for the safe message, then remove the drive.

I'd rather be phishing?

"Give a man a fish and you feed him for a day. Teach a man to phish and you feed him for a lifetime."
- paraphrasing a Chinese Proverb
Phishing is the act of catching unwary users of email and tricking them into giving personal information or clicking on a link for the purpose of installing malware or other nefarious actions. Phisherman are never so crude as to say, hey look, you don't know me but click here please. Instead they pretend to be someone you know having already stolen your friends email address book, or pretend to be a legitmate business that you deal with, or provide some incredible other that is too good to pass up.
  • Never open or reply to any e-mail when you are unsure of the sender.
  • If it is too good to be true - it is.
  • E-mails that appear to come from a known entity (like your bank, the government, someone from your old high school, etc), often are spoofed e-mails and do not come from them at all.  
    • If you see an e-mail from your bank - sign into your account directly from the official website - NEVER follow the helpful link they send you. That helpful link will take you to a fake website that will save your account # and password for later theft.
    • If you get an e-mail notice from the government about your tax info, think about it. How did they get your e-mail address? And the IRS does not use email; they send you a nicely registered letter requesting your presence at an audit.
The internet is seeing a continuing dramatic rise of e-mails designed to fool you into action; and it does work or they would not be doing it.  Some of the most recent tricks are:
  • Notices of copyright/trademark infringement
  • Notices from the BBB about a complaint
  • Notices from banks requesting an update of some kind or another
  • Notices about problems with an electronic check/deposit (ACH)
  • Notices from the Government looking for you to update your tax data
  • Notices about problems with your tax return 
  • E-Mails from old friends (they get that data from Facebook, Linkedin, etc, etc...)
  • E-Mails asking you to help a friendly prince get his inheritance out of a country controlled by an unfriendly tyrannical government
  • etc, etc, etc...
Bottom Line

This is nothing new - just a reminder to practice safe computing. Below is a screenshot of e-mail quarantined by one person in one morning; you can clearly see  examples of phishing.

(Lack of) Computer Security

Treat your password like your toothbrush. Don't let anybody else use it, and get a new one every six months.
~Clifford Stoll
If you use Google news you can customize it to include specialized topics of interest. One of my news "extras" is Computer Security and recently it was full of depressing news about serious security violations

Medical Record Theft At Sutter Health
Information stolen on more than 4 million patients of a major Northern California health care provider. What's unusual about this incident is not some clever hacker but a thief who broke a window with a rock and stole a PC containing patient records.
"Over the last two years, health care organizations have reported 364 incidents involving the loss or theft of information ranging from names and addresses to Social Security numbers and medical diagnoses on nearly 18 million patients – equivalent to the population of Florida."
Water utility hackers destroy pump, expert says
Hackers may have destroyed a pump used by a US water utility after gaining unauthorized access to the industrial control system. Many industrial control systems rely on passwords that are hard-coded and it looks like Russian hackers stole the password from the company that made the equipment. The hackers (after much experimenting) managed to burn out a water pump by rapidly turning it on and off. One expert noted, “These things are connected to the Internet in ways they shouldn't be.”

This is "a really big deal".

Hackers attack Norway's oil, gas and defence businessesIndustrial secrets and information about contract negotiations had been stolen from at least 10 firms according to Norway's National Security Agency (NSM). Normally attacks like this would be kept secret but the NSM wants to world to know about these very skillful hackers.
"The attackers won access to corporate networks using customised emails with viruses attached which did not trigger anti-malware detection systems. ...  the email messages had been sent to specific named individuals in the target firms and had been carefully crafted to look like they had come from legitimate sources."
Facebook admitted that hackers are breaking into hundreds of thousands of Facebook accounts every day.
"Don’t use the same password and username combination for multiple websites. Use an online password manager to keep track of your different accounts."

Bottom Line

Hacking is not just nerdy teens having fun at your expense. There is money to be made selling identity information and there are government sponsored hackers (Russia, China) seeking weakness for cyber-warfare or corporate espionage.

Check out this article on the 25 worst passwords
http://www.telegraph.co.uk/technology/news/8898482/25-worst-web-passwords.html

Update
Recent news is claiming that the Utility pump was a false alarm. No proof that hackers destroyed it. Perhaps. But the risk is real and it is only a matter of time before real damage is done by hackers.

Education for the masses

“I never let schooling interfere with my education.”
-Mark Twain
A year ago I wrote about Online College courses; most notably the Khan Academy. A recent Wired magazine article describes how Khan is a complete game changer, and how children have been able to advance at a blistering pace using Khan's materials. So what does the public school system think of it?
So what happens when, using Khan Academy, you wind up with a kid in fifth grade who has mastered high school trigonometry and physics—but is still functioning like a regular 10-year-old when it comes to writing, history, and social studies? Khan’s programmer, Ben Kamens, has heard from teachers who’ve seen Khan Academy presentations and loved the idea but wondered whether they could modify it “to stop students from becoming this advanced.”
Bottom Line

American grade school education is not "about the children", nor is it about what is best for the children. It's about conformity. It's about social engineering and promoting "correct thought". Only a factory-assembly-line educational system, a "we don't care about individual", would complain about students becoming too advanced.

Body Hacking

“And computers are getting smarter all the time: scientists tell us that soon they will be able to talk to us. (By they I mean computers: I doubt scientists will ever be able to talk to us.)”
-Dave Barry

Scary story of the day:

Black Hat researcher shows it is possible to remotely control a diabetic's insulin pump without person's knowledge

Bottom Line

Technology is wonderful but most inventors and companines fail to take security seriously. Hackers can turn off pace markers and most any other medical device that responds to remote signals. If your life depends on technology, ask your doctor about the risks of hacking or even "Noise" or magnetic fields disabling your device.

Is Progress Slowing Down?

“When Moses was alive, these pyramids were a thousand years old. Here began the history of architecture. Here people learned to measure time by a calendar, to plot the stars by astronomy and chart the earth by geometry. And here they developed that most awesome of all ideas - the idea of eternity.”
-Walter Cronkite
An editorial by Matt Patterson at pajamasmedia.com asks if the times are a'changing.
In his penetrating new book The Great Stagnation, economist Tyler Cowen ... calls the period from roughly the early 19th to the mid-20th centuries the era of “low hanging fruit.” According to Cowen, technological advances in this period were relatively easy to produce and exploit, resulting in a staggering explosion of living standards.
But by around 1970, most of this low hanging fruit had been plucked and growth rates began to slow. Indeed, growth rates are “lower today than before 1973, no matter what exact numbers you settle on for the absolute living standard.”
There are at least two reasons for this.

1. The age of cheap resources is ending. Many companies relied on cheap water, electricity, iron, etc for production. We've used up the easily accessible resources ("low hanging fruit") so what remains costs more to process and there is now global competition to use it as China and India industrialize and extend middle class comforts to billions of people.

2. The complexity of manufacturing keeps increasing. Compare the engine of a car from 1950 to today. Robots help with the assembly but there are more moving parts and of greater sophistication. Consider the clean room requirements and requirements of perfection on a small scale to create computer microchips.
Complexity makes it harder to create and produce new products.

There is an interesting flip side to the second point. This is the Information Age and while computer software also increases in complexity, well built software hides the complexity to produce "tools" that are easy to use and promote the creation of more information products. Anyone now can create publication ready books, art works, web services, etc on computers. So complexity enables information products and hinders physical products.

You may think, no problem, we'll just transition to an information society where the majority of workers are information workers. In the past the “creative destruction” of progress might end one industry like horse buggy making but resulted in an even bigger automotive industry. However software advances don't do that. Advances in software tend to decrease or eliminate jobs like travel agents. McDonald’s plans to eliminate cashiers in many of its European restaurants, replacing them with touch-screen ordering systems.

Internet companies can be worth more than old fashion manufacturing and reach hundreds of millions of customers and yet employ very few.
[Economist Tyler] Cowen notes that Google employs a mere 20,000; the increasingly ubiquitous Twitter only 300. Facebook has millions of users, but only about 1,700 workers.
For comparison, General Motors employs 209,000 people around the world.

Bottom Line

Again from Matt Patterson,
Unfortunately, politicians in the “low hanging fruit” period made policy decisions based on the assumption that the growth rates of that era — and their corresponding tax revenues — would continue indefinitely. And the American public, seeing successive generations do better than prior ones, came to expect this was the natural order of things. Both governments and individuals borrowed against a future they assumed would be richer and more technologically wondrous than the present.
Patterson observes from history that no civilization lasts forever.The ancient Greeks created the myth of the Cyclops to explain even more ancient fortresses with walls of giant stones that no one knew how to move. It must have been built by giants. In reality it was the Greeks own ancestors several hundred years before.  "The Great Pyramid of Cheops was the largest building in the world until well into the modern era, and still stands after nearly five millennia". And yet a few centuries after its making, Egypt fell and the world forgot how to make them.

Bubbles result when people say, "This time it's different". But the Internet bubble burst, the housing bubble burst (many times) when expectations exceed reality. Have we been living in a technology bubble of 200 years?

The Future of Advertising

"At bottom, robotics is about us. It is the discipline of emulating our lives, of wondering how we work."
-ROD GRUPEN, Discover Magazine, June 2008
I like to keep on eye on technology and how it changes our life. Recently Toyota annouced a new spokeswoman, Hatsune Miku, a young Japanese singer who has been extremely popular in her homeland. Nothing unusual about that. Until you learn that Hatsune is computer-generated based upon a poplar anime character.

There have been computer generated actors in the past. Long ago there was Max Headroom. And more recently Jar Jar Binks. Usually these are rendered over a human actor who supplies the motions. I suspect Hatsune is totally drawn from comptures but she does use samplings of real human voices.

Bottom Line

Personally I'm not suprised by this. I'm actually more suprised that we have not seen more of this. Most animated films are now computer drawn with robotic models, not hand drawn. As the cost comes down I expect computer actors will replace live one with greater frequency.

Passwords

"Some users will provide their password to a stranger who says he is from their company's IT department."
-Amir Lubashevsky
If you use computers than you'll be asked to supply a "secure" password. When I wrote about this two years ago, I recommended using the initial letters of a phrase like "tbontbtitq" for "To be or not to be, that is the question" as something not found in a dictionary yet easy to remember. Sometimes it is possible to be too clever. When physicist Richard Feynman worked on the Manhattan Project to create the first nuclear bomb, he found that many safes could be cracked at the super-secure site with combinations based upon PI = 3.14159 or e = 2.7182818.

This morning I read an article on baekdal.com that suggests we are looking at passwords the wrong way. Reliable security it argues, comes from password length, not password complexity. Yes complexity helps. A password like "jskerv" with only characters can be cracked in 1 month using brute force. But "J4fS<2" with mixed case, symbols and numbers would take 219 years to crack. The problem with complex passwords is remembering them. A password at the office is defeated if you post it on the wall of your cube.

Baekdal recommends a three word password like "this is fun". A pure brute-force attack for 11 characters would take over 1 million years. An attack combining common words would take over 2000 years, still very secure. If spaces are not allowed in your password, try "this-is-fun".

Since most password algorithms measure complexity, not length, you may find a password like this rated as "weak." And yes a single word from a dictionary with 11 characters would be weak. But not three words. Imagine how many three word sentences exist!

Some passwords require symbols, numbers, etc. I find this annoying and occasionally forget the new password for some bank that requires two numbers or some other pattern different from what I use. This results in keeping a list of passwords which in itself weakens security.

Bottom Line

Find a password that is easy to remember but long and either multi-words or letters taken from some phrase you remember. Can you guess this phrase?  "hb2yhb2y"

Pink Slipped

“The crowning fortune of a man is to be born to some pursuit which finds him employment and happiness, whether it be to make baskets, or broad swords, or canals, or statues, or songs”
- Ralph Waldo Emerson
Today I recommend a delightful blog at Forbes.com by a Journalist/editor who was recently "downsized" and joined the unemployed. It's called Pink Slipped.

She offers these tips on finding a new job:

1. Men help. Women don't.
Male friends provided job leads. Female friends provided emotional support.

2. Be flexible, or die.
She has offered a part-time job as a copywriter but had no idea what that meant. After looking it up she accepted despite having no experience at copywriting. It pays well.

3. Getting downsized is good for you.
It can lead to new opportunities like her new blog, Pink Slipped, and the copywriting gig.
Bottom Line

Let everyone know you are looking for work and be willing to try new things. The job I currently have I had rejected when I first saw it advertised. The job description did not fit my expectations in the early period of unemployment. Several months later a different recruiter got me an interview and a job offer. Only afterwards did I realize I had rejected the job before.

Most Boring Day in History

An author is a fool who, not content with boring those he lives with, insists on boring future generations. - Charles de Montesquieu
Computer programmer William Tunstall-Pedoe has calculated that April 11, 1954 is the most objectively dull day since 1900. On that day the most significant events were a general election in Belgium, the birth of a Turkish academic and the death of footballer Jack Shufflebotham.

Mr Tunstall-Pedoe's computer program, called True Knowledge, was fed 300 million facts about "people, places, business and events" that made the news and this particular day was outstanding in its obscurity.

Bottom Line

"Nobody significant died that day, no major events apparently occurred and, although a typical day in the 20th century has many notable people being born, for some reason that day had only one who might make that claim - Abdullah Atalar, a Turkish academic.", said Mr Tunstall-Pedoe's .

Email Etiquette

"Diamonds are forever. E-mail comes close." - June Kronholz

Website TheOatmeal.com takes a humorous look at email etiquette.  My only fear is that the message is too subtle - some people may have no clue what is wrong with each example.

The title is "If you do this in email, I hate you." Here's a summary of the errors displayed.

1. Clinging to old technology and not using the power of the Internet. Why fax anything anymore? At my company we each sign (and fax to HR) a one page document agreeing that our email signature will be legally binding. Now no more faxes, our email response is sufficient.

2. Asking for a resend of information instead of searching your own email archives.

3. Chain letters to dozens of friends. Personally I find it very sad when persons forward a chain mail and don't clean it up - instead leaving the history of every previous person it was ever sent to.

4. Super long automatic email signatures or using graphics in your signature. This make the email unnecessary large and takes up space.

5. Besides a fax response (see cartoon #1) the 5th cartoon seems to be more a dig at non-disclosure agreements in general.

6. Email != FTP (File Transfer Protocol) - don't send giant files by email. They are slow to download and fill up the mail box space.

7. Email != Collaborative Editing Software. Note all the Re: Re: ... in the title showing how many times this email has been bounced back and forth. I would be guilty of using email this way since I've never worked with collaborative editing software. The closest I suppose is using source control software and Change Tracking to see who edited what. Source control are programs that let you "check out" a file, modify it, then check it back in. A checked-out file is locked and no one else can change it while you own it.

8. Unsubscribe - just like the cartoonist, I hate it when I have to sign in to unsubscribe because I may have no clue what my account ID and password are. A good unsubscribe knows who you are.

9. Don't overly decorate your email with background wall paper, and added art elements, etc. Again this added to the size of the email file.

Bottom Line

Email etiquette is interesting. Should it be as formal as snail mail or as informal as twitter? Should you use abbreviations like LOL, FYI, etc? Is it OK to spam your friends? What do you think?

Social Steganography

"I don't at all like knowing what people say of me behind my back. It makes me far too conceited." - Oscar Wilde
Today I recommend the article, Social Steganography: Learning to Hide in Plain Sight. I have a friend with a 13-yr-old daughter and the daughter loves facebook (FB). The mother is concerned about FB and carefully watches her daughter's page for inappropriate topics and language. And issues have come up - one boy asked for sexy photos for example.

In the article cited above, the author describes a similar situation where a mother comments on her daughter's every post which "scares everyone away". The daughter, Carmen, has to think - How will my mother respond to my post? Will she freak out? So Carmen has learned to comment in "code" using references her mother will think is safe but her friends know differently. The example given is quoting lyrics from Monty Python's "Always Look on the Bright Side of Life" a happy song on the surface but if you know the story, "Life of Brian", it's sung by men being tortured to death by crucifixion.

The art of hiding secret messages in plain sight is called Steganography. Youth are forever creating new slang words to hide what they are saying. It's fat, or cool or bad. Parents are meant to be confused - does bad mean good?

Bottom Line

This gives a whole new spin to comments on FB. I often see song quotes or odd statements that have no context (for me). I'll have to start looking past the quotes to find the hidden message.

Google Earth

The letter A
"I'd like to teach the world to sing
In perfect harmony
I'd like to hold it in my arms
And keep it company."
-Coca Cola ad song from 1971
If you like maps, you'll love the web application, Google Earth. It allows you a bird's eye view of much of the planet from various heights (some regions are more detailed than others.) The app has been put to many uses.
  • Searching the earth for items that look like letters of the alphabet (so you can spell with geography?)
    (in Australia) (Netherlands) (British hedgerows)
  • A cousin of my commented on Facebook about using Google Earth flight simulator to "fly" through canyons. Not easy, he said.
  • The town of Riverhead in Long Island uses Google Earth to locate residents who have pools but have not paid for a pool permit. They have collected $75,000 in fees so far.
  • Looking for undiscovered meteor craters (like deep in the Sahara Desert).
Bottom Line

As with all technology, it can be used for good or evil. Security officials fear that terrorists will use Google Earth to scout out a location and plan an attack with accurate images. For this reason some locations on Earth are deliberately blurred by Google Earth.

Who's reading your email?

“Relying on the government to protect your privacy is like asking a peeping tom to install your window blinds.”
- John Perry Barlow

When you use the Internet, you can NEVER assume any privacy. Consider email for example. Your text is moving in the clear between many servers and can be easily intercepted. It is stored on a server at the email company where police and others can request to see it with a court warrant. Any employee at the email company with access to the server could read the email (though it may violate company/corporate privacy regulations.) Don't think this could happen? There are many examples of Civil employees caught reading the DMV records or tax records of celebrities, friends and enemies.

Another technology that puts privacy at risk is Chat. It's not uncommon for employees within a company to chat with other. But if the chat is run by an outside company, then confidential conversations can compromised. At my last job, the IT department came to fear this and required that everyone only use a new Chat service that was run within the company.

One problem today is that we have little clue who owns or operates services on the Internet. Your favorite site or service could be running in China with a history of disregard for privacy. Recently one of the pioneering chat companies, ICQ, was sold to a Russian company where the Russian "secret service" is entitled by law to any information it wants.

Bottom Line

Anything you put on the Internet may be leaked or become public. Don't assume privacy. I'm often annoyed by sites where I register and then they email back a welcome letter with my password printed out in clear text.

I read yesterday of a case in Europe where a brother privately boasted of a murder on Facebook to his sister. She turned the message over to the police.

Data Loss

"We must embrace pain and burn it as fuel for our journey"~Kenji Miyazawa

In memory of my C: drive at the office which has died, I offer The five stages of data-loss grief from MSNBC.com:

Stage one: Denial
"No. This can't be happening. Maybe if I reboot again it'll work."

Stage two: Anger
"I've lost everything! I'm so mad. Why didn't I backup the files?"

Stage three: Bargaining
"Maybe I can download some software and try to recover some files. Or perhaps hire someone for file recovery?"

Stage four: Depression
"My email, my photos! Gone forever. I can never replace them."

Stage five: Acceptance
"I promise I'll back up everything in the future"

Bottom Line
Data loss eventually strikes. Prepare for it.
