Paul Graham, “Hackers & Painters” A Summary In “Hackers & Painters, Paul Graham, computer science expert and painter, explains examines what motivates computer programmers to do what they do, as well as attempt to answer many of the questions that have arisen with computers. He explains the word “hacker” has more than the one definition most of us are familiar with. The hackers who Paul Graham refers to throughout the book are the good computer programmers who have made all that we have real. Graham's first chapter, "Why Nerds Are Unpopular," tries to explain why smart kids are at the bottom of the food chain in high school and what their priorities are. While writing about nerds, Graham talks about his own progress to become computer scientist and painter. He explains the similarities between painters and computer hackers, including the desire to make existing things better.
(Reuters) - Citigroup, the third-largest U.S. bank by assets, has told government officials that about 3,400 of the customers whose credit-card information was hacked have suffered about $2.7 million in losses, the Wall Street Journal reported. http://www.reuters.com/article/2011/06/28/us-citigroup-idUSTRE75R7G220110628 The exposed account information included names, account numbers, email addresses, and contact details http://www.informationweek.com/security/attacks/citigroup-confirms-hackers-stole-custome/230500141 Citi apparently discovered the Citi Account Online breach in May, during routine systems maintenance. http://www.informationweek.com/security/attacks/citigroup-confirms-hackers-stole-custome/230500141 Basically after you logged into your account as a Citi customer, the URL contained a code identifying your account. All you had to do was change around the numbers and boom, you were in someone else's account. So if the URL was something like citibank
Being too visible on the internet is dangerous The Internet plays an important role in modern people's lives. Most of us use the Internet on a daily basis. It is mostly seen as a way of entertainment, but there are some risks and dangers involved. Already as children people often register themselves in online communities where they can connect with others, upload pictures of themselves and share information about their actions. Unfortunately, places like these are often filled with pedophiles, who usually add their victims through various messengers and start chatting. They show themselves through a web-camera and such, and in return they ask for some pictures of the victim. Sometimes the youngsters are too gullible and they do as told. The consequences might be very extreme. There have been cases where the victims find photos of themselves naked on the Internet. The worst part is that sometimes they can't handle the pressure and comm...

Arvutimaailma tegija Tim Berners-Lee Üldiselt Timothy John Berners-Lee (sündinud 8. juunil 1955 Londonis) on inglise arvutiteadlane ja Massachusettsi Tehnoloogiainstituudi professor. Tema suurim leiutis on võrguprotokolli World Wide Web loomine. Häkker Tudengina Oxfordi ülikoolis jäi Tim Berners Lee koos oma sõbraga vahele häkkimisega ning tal keelati tegeleda asutuse arvutitega. Selle tulemusena (mõnedel allikatel lihtsalt igavusest) ehitas ka kättesaadavatest asjadest (muuhulgas M6800 protsessorist ja vanast telekast) endale töötava arvuti. Tehnoloogiline innovatsioon näis olevat Tim Berners Lee'l geenides, sest ta vanemad olid matemaatikud, kes töötasid Manchester Mark1-ga, ühest esimestest elektroonilistest arvutitest. Suur saavutus 25. detsembril 1990 õnnestus tal luua esimene toimiv ühendus HTTP kliendi ja serveriga internetis Robert Cailli...

The computer has greatly improved our lives today Nowadays, computers are a big part of our lives and they have made pretty much everything simpler and more entertaining. On the other hand, the misuse of them can be extremely dangerous. On the positive side, computers are great tools for school and different jobs. Using the Internet it is possible to communicate with each other and access to information faster. Another advantage is that almost the whole world has access to those technological inventions, so if someone lives in Australia, it is surprisingly easy for them to find a friend from Europe. On the negative side, there are lots of hackers who can damage big companies or leak personal information. In addition to this, people spend too much time in front of computer screens and that causes visual illness, sickness, stress, muscular pains, etc. Furthermore, there is a lot of trash on the Internet, f...
Most needed professions in Estonia in 21st century All people in society have a role. All adults should have jobs. Some professions are more needed in society than others. In Estonia we need mostly newer professions, connected with computers. I think doctor is a most needed profession. We have so many illnesses and nobody knows what it is. We need people, who help us to cope with them. In Estonia doctors earn not much money, that's why a lot of them go to foreign country to work and to earn their living. The second most needed profession is connected with computers. More growing computer using and replacing jobs with robots and computer programs leaves some people without jobs. But companies need somebody to look after the computers and computer repairmen who know how to fix the computer problems. There are viruses computers and hackers who try brake in computers and all companies computers need to protected from those threats. ...
All people in our society have a role. All adults should have jobs. That means that they need to choose a profession. Some professions are more needed in our society than others. Nowadays in Estonia we need mostly newer professions, connected with computers and things like that, bust also some older professions... The most needed profession is builders. The cities grow and new buildings are being razed. When you walk in the streets then you can see everywhere that some buildings are being repaired, or some older ones are being demolished to make space for newer and bigger buildings. Some old houses are being restored like they used to be in the past. In the Centrum new and modish glass buildings are being constructed. That gives the builders and all the people connected with construction and building jobs. And we need more of those people in our society. The second most needed profession is connected with computers. More...
What are the most needed professions in the 21st century? People are often asking me what are the most needed professions in the 21st century. I've understood that in Estonia we need mostly newer professions, the ones that are connected with computers. In my opinion one of the most needed professions is a doctor. I know we have a lot of doctors, but a lot of them go to a foreign country. Mostly because of the low salary in Estonia. In my opinion the second most needed profession is a really good goverment employee. Estonians want some changes in their lives. Our goverment employees only think about earning more money. The third most needed professions is actually needed the most, it's connected with computers, as I first mentioned. More growing computer using and replacing jobs with robots and computer programmes leave some people without jobs. That's why people need to know more and more about computers. Companies nee...

New Media Economy Social media information and data collection and security In this brief essay, i would like to focus on the social media platforms in our moren society. How people use them, what kind of information we give away, what companies will do with this. Information sharing and data protection has become very popular theme in the recent few years. People care more about their privacy and avoid „big brother“ foreshadowing. It is important to know what social media platforms promise and are they really going to keep it. Users should think about what they share and what kind of information they generate. Because it is all recorded and some info can be traced back to real people. Privacy and data protecion topics are becoming more and more important and the amouts of data generated is becoming larger. When wrongly access this kind of data, a lot damage could be done by criminals. Users privacy settings should be reviewd and ...
Silicon Valley Could you reproduce Silicon Valley elsewhere, or is there something unique about it? It wouldn't be surprising if it were hard to reproduce in other countries, because you couldn't reproduce it in most of the US either. What does it take to make a silicon valley even here? What it takes is the right people. If you could get the right ten thousand people to move from Silicon Valley to Buffalo, Buffalo would become Silicon Valley. That's a striking departure from the past. Up till a couple decades ago, geography was destiny for cities. All great cities were located on waterways, because cities made money by trade, and water was the only economical way to ship. Now you could make a great city anywhere, if you could get the right people to move there. So the question of how to make a silicon valley becomes: ...
