Write for money 2

Of the many computer security measures available to end users, none is more confusing to the novice than the firewall. I can understand why. Unlike anti-virus or anti-spyware tools, a firewall doesn’t immediately telegraph what it does. I wouldn’t be surprised if many people thought it was designed to prevent fires inside your computer. (It doesn’t.)

I’m writing this post for novices, so please forgive any over-simplifications. Basically, a firewall is software (or hardware) that blocks malicious attacks on your computer from coming through over the internet. But wait, you might say, don’t most malware attacks, like viruses, come over the internet? They do, but the difference is that with viruses and spyware, there is generally some human interaction that starts the infection: You might open an infected email or visit a bad website, for example. Anti-virus software helps in these situations where you’re actively involved in the process.

But believe it or not, many, many computer attacks come over the internet even if you aren’t at your desk and your web browser and email client are closed. Thanks to the millions of zombie PCs in the wild, attack computers are constantly scanning the internet, almost at random, looking for unprotected computers to attack. These zombies continuously scan for security holes (and I won’t go into the intricate details of how this works), many of which are caused by Windows. It’s like walking down the street, trying all the car doors to find one that’s unlocked. If your computer is connected to the internet, they will find you—fast. Before a firewall was added to Windows XP in Service Pack 2, it was commonly held that an unprotected Windows machine connected to the internet would be infected with some form of malware within 20 minutes and in some cases as quickly as 4 minutes. Just plug it in, and the bad guys do their work.

So where does a firewall come in? A firewall plugs the security holes I mentioned and blocks that bad, random traffic from coming through to your computer. Anti-virus won’t help you in many of these cases. You really need a firewall to stop a lot of this stuff.

The good news is that you probably already have a firewall up and running. The best firewalls are found inside router hardware (either wired or wireless) that you attach to your broadband modem. Every router I’ve ever tried has the firewall turned on by default, but check in the configuration tool to make sure it is. It should be easy to find. You usually need not configure it any more other than turning it on.

Don’t have a router? Turn on the Windows Firewall by going to the Windows Firewall control panel (in XP or Vista). It also needs no additional configuring, and in my experience it is just as good as using a third-party firewall software product. You do not need both a router-based firewall and the Windows firewall. One will do.

Once your firewall is on, you can largely forget it and let it do its work. You may not notice this silent friend protecting you in the background, but believe me, you’ll notice if you turn it off.

Exchange support, true push email, pro-level security and configuration features — they’re all in store for the iPhone as Apple tries to position its touch-screen handset as a true competitor to BlackBerrys, Palm Treos, and Windows Mobile devices.

Apple VP Phil Schiller said the new features, which will allow business users to instantly sync their Exchange email, contacts, and events, will be in the next iPhone software update. (No word yet on when the update will arrive.) (Update: Looks like it won’t be until June.)

Specifically, the iPhone will get support for Microsoft’s ActiveSync protocol, which taps into-and syncs with-corporate Exchange servers, pulling info into the iPhone’s existing email, calendar, and contacts applications. In the past, large business and corporate email networks have avoided using the iPhone because of compatibility, but now, that will no longer be an issue.

Also on tap are such must-have business features as Cisco VPN support (for creating secure tunnels into corporate servers), remote iPhone configuration (for rolling out software to an entire fleet of iPhone-toting employees), remote wipe for lost or stolen iPhones, and enterprise-level Wi-Fi security (including WPA2 encryption).

All these new features will surely make the iPhone, which hasn’t been able to sync with corporate servers until now, much more attractive to big business. (The iPhone originally launched with IMAP support, which lets you sync with IMAP-enabled Exchange email, but it doesn’t work with events or contacts, and there’s no push email support.) If you’ve been stuck with a BlackBerry for work and have been dying to switch over to an iPhone, now’s the time to pipe up.

Of course, the iPhone still lacks a physical QWERTY keypad, which will give many enterprise users-especially those who love cranking out messages with their thumbs-a moment of pause.

The announcement came during an event Thursday in Cupertino, during which Apple is rolling out details on its upcoming iPhone software development kit. Stay tuned.

VH1 is partnering with Dr. Drew for the reality series “Celebrity Rehab with Dr. Drew.” The project, consisting of eight one-hour episodes, is slated to premiere on January 10, 2008 at 10pm*. VH1 will announce the cast closer to the premiere date. It’s hard to escape all the news about the all-too-public displays by celebrities under the influence and their subsequent stints in rehab. But what actually happens on the inside? In a television first, the highly respected Dr. Drew, a practicing MD and professor at KECK USC School of Medicine, will give viewers an unflinching look at exactly how the rehab process works and what it feels like for participants. Dr. Drew hopes to use his celebrity patients to humanize the process and show viewers that treatment is a viable way to break the cycle of addiction. “The road to sobriety is not easy and rehabilitation and the recovery process are not to be taken lightly.” said Dr. Drew Pinsky. “My goal is to lift the veil and help my patients, as well as viewers, understand that if not taken seriously, addiction is a disease that will kill you.”

Web traffic is the amount of data sent and received by visitors to a web site. It is a large portion of Internet traffic. This is determined by the number of visitors and the number of pages they visit. Sites monitor the incoming and outgoing traffic to see which parts or pages of their site are popular and if there are any apparent trends, such as one specific page being viewed mostly by people in a particular country. There are many ways to monitor this traffic and the gathered data is used to help structure sites, highlight security problems or indicate a potential lack of bandwidth – not all web traffic is welcome.

Some companies offer advertising schemes that, in return for increased web traffic (visitors), pay for screen space on the site. Sites also often aim to increase their web traffic through inclusion on search engines and through Search engine optimization.

This being February 29 — Leap Day — today is costing you an extra day’s interest if you’re repaying a debt. On the bright side, it’s earning you a tiny bit more on your bank deposits.

Whom do we have to thank — or curse — for this extra day every four years? Julius Caesar and his lover, Cleopatra.

In 48 B.C., Julius Caesar was in Alexandria, Egypt, absorbing the culture and science — and decadence — of Cleopatra’s capital. There he learned from an old sage named Acoreus about Egypt’s calendar, which had a leap year.

At the time, the Roman calendar did not. Like most ancient calendars, it was based on the phases of the moon, which in one cycle takes about 29.5 days. But 12 months of 29.5 days doesn’t equal the true length of the year as measured by the orbit of the Earth around the sun. It’s off by 11 days, so anniversaries, holidays, and entire seasons to drift backward on lunar calendars.

The ancient Egyptians had realized this and created a calendar 365 1/4 days long — with the fraction averaged in by adding an extra day every four years.

When Caesar returned to Rome, he created a 365-day calendar with a quadrennial leap year, adding the extra day in February.

A minor hassle for some, perhaps, but certainly better than the alternative faced by the Romans. Back in 45 B.C., for instance, their lunar calendar had drifted backward by 80 days — nearly three months. Spring had become winter, and autumn came in the summer months.

To correct this, Caesar decreed that 45 B.C. would be 445 days long. Think about the extra interest on 80 extra days! No wonder they called it "The Year of Confusion."

The Jargon File contains a bunch of definitions of the term ‘hacker’, most having to do with technical adeptness and a delight in solving problems and overcoming limits. If you want to know how to become a hacker, though, only two are really relevant.

There is a community, a shared culture, of expert programmers and networking wizards that traces its history back through decades to the first time-sharing minicomputers and the earliest ARPAnet experiments. The members of this culture originated the term ‘hacker’. Hackers built the Internet. Hackers made the Unix operating system what it is today. Hackers run Usenet. Hackers make the World Wide Web work. If you are part of this culture, if you have contributed to it and other people in it know who you are and call you a hacker, you’re a hacker.

The hacker mind-set is not confined to this software-hacker culture. There are people who apply the hacker attitude to other things, like electronics or music — actually, you can find it at the highest levels of any science or art. Software hackers recognize these kindred spirits elsewhere and may call them ‘hackers’ too — and some claim that the hacker nature is really independent of the particular medium the hacker works in. But in the rest of this document we will focus on the skills and attitudes of software hackers, and the traditions of the shared culture that originated the term ‘hacker’.

There is another group of people who loudly call themselves hackers, but aren’t. These are people (mainly adolescent males) who get a kick out of breaking into computers and phreaking the phone system. Real hackers call these people ‘crackers’ and want nothing to do with them. Real hackers mostly think crackers are lazy, irresponsible, and not very bright, and object that being able to break security doesn’t make you a hacker any more than being able to hotwire cars makes you an automotive engineer. Unfortunately, many journalists and writers have been fooled into using the word ‘hacker’ to describe crackers; this irritates real hackers no end.

The basic difference is this: hackers build things, crackers break them.

If you want to be a hacker, keep reading. If you want to be a cracker, go read the alt.2600 newsgroup and get ready to do five to ten in the slammer after finding out you aren’t as smart as you think you are. And that’s all I’m going to say about crackers.

Some people believe that earning the most money will make them incredibly happy. What they probably don’t know is that being incredibly happy may not earn them the most money.

A new study finds that when it comes to financial success, you’re better off being a moderately happy person rather than someone who’s chronically ecstatic.

Mild Is Beautiful

Researchers at the University of Virginia, the University of Illinois in Urbana-Champaign, and Michigan State analyzed several sets of data in a paper recently published in Perspectives on Psychological Science. Their conclusion: Mildly happy people — those who rank themselves a 7 or 8 on a life-satisfaction scale of 1 to 10 — achieve more than the blissful 10s.

"The people in our study who are most successful in terms of income, education, and career are mildly happy most of the time," said Ed Diener, a psychology professor at the University of Illinois.

Numerous studies have found that happy people enjoy an advantage over malcontents: Cheerful people earn more, enjoy better health, have closer relationships, and live longer, among other benefits. But in this case, researchers wanted to explore how happy you need to be to get those perks. Do the 10s enjoy the highest well-being in all areas of life?

Emotional Rescue

The answer is no — and there may actually be a downside to scoring at the top of the scale. In a survey of more than 100,000 people in 96 countries, for example, the 8s on the 1-to-10 scale perform best in the realm of achievement.

Diener surmises that the 8s benefit from the creativity and energy of happiness, which help them stay committed in the pursuit of long-term goals and overcome obstacles along the way. But the 8s also maintain a touch of worry, stress, or internal dissatisfaction that motivates them to strive for more.

"Emotions steer our behavior, and they are there for a reason — to help us function better," says Diener.

Swiss psychologist Norbert Semmer, for example, studied people who were dissatisfied with their work, following them over a period of time. Not surprisingly, these workers were more likely to quit their jobs and find a new situation. While a few people were simply chronic complainers, many of those studied were happier in their new workplace. In other words, negative emotions played an important role in improving their circumstances.

Sociability Trumps Money

Among the studies reviewed, researchers analyzed a survey of college freshman in 1976, who were asked to rank their happiness. Twenty years later, a follow-up survey of the same people found that those who scored in the top 10 percent in well-being reported average salaries of $62,681, compared to $54,318 for the bottom 10 percent. But the next-to-happiest group was earning the most: $66,144. Analyses of long-running panel studies from Australia, Germany, and Britain produced similar results.

On the other hand, if you define success in terms of relationships, the joyful 10s are the clear winners. In a survey of current college students, the "very happy" group was more gregarious and ranked higher in self-confidence, energy, number of close friends, and time spent dating. (Those who ranked themselves merely "happy" had higher grade point averages, attended class more frequently, and were more conscientious.)

"The 10s are more sociable and positive, so people like them," says Diener, and the global survey demonstrated similar results. (I interviewed several millionaire entrepreneurs this week and they all ranked themselves 10s. Energy, confidence, and relationships may be the key. See my blog for that story.)

To Misremember Is Divine

The effusively happy tend to look at their relationships through rose-colored glasses. In a separate study of dating couples not included in this paper, Diener’s research team randomly beeped participants while they were with their partners, and asked them to write down how happy they were. Then they surveyed them at a later time about their relationships.

Some participants reported being happier in retrospect than they had felt in their moment-to-moment account. "People who misremembered in a positive direction were more likely to be together six months later," Diener says.

In other words, the 10s tend to idealize their partners and look for the best in them, leading to more enduring and upbeat relationships. Alternately, the lack of satisfaction that drives the 8s to want more in their work lives might also prompt them to be more critical of their partners, to more readily see their faults — and to be more willing to look around for something better.

A Positive Negative

But while relationships are better for the joyous, it turns out that there’s a big deficit to perpetual euphoria: Super-happy people don’t live as long as the moderately happy, according to a long-term study of gifted children. "We were shocked that the happiest people didn’t live longer," says Diener.

He speculates that the most upbeat people may not take symptoms of illness seriously, or may follow a physician’s recommendations in a halfhearted way. Or they may take foolish risks, such as the active 77-year-old Californian who went biking during a heat wave and later succumbed to heat stroke.

In addition, just as the physiological arousal associated with chronic stress takes a toll on health, so too can the sustained arousal of intense positive emotions, Diener suggests.

"People who chase continual emotional highs will usually fall short because the biological cards are stacked against their being able to sustain this emotional intensity," he writes in an upcoming book on well-being. "In the quest for continuing intense positive emotions, some individuals turn to drugs."

Pursue Happiness at Your Own Pace

The upshot? If you feel generally satisfied with your life, your work, and your relationships most of the time, think twice before buying into the self-help movement and its search for a continuous streak of "peak moments."

"Happiness, like spirituality, is partially a private pursuit, defined by individuals based on their personal values," says Diener. "Be wary when people tell you to live for the moment, to strive for an exciting life, or that you ought to be happier. Chasing super-happiness is a mistake that can lead you astray and be self-defeating."

happy new year everyone!

merry christmas to all!
