Do you want to learn how to protect your computer from viruses and other threats, but don't know where to look? October is National Cyber Security Awareness Month, and it might be a good time to take a look at some of the tips and facts offered by the U.S. Department of Homeland Security's Computer Emergency Readiness Team (US-CERT).

Apparently hackers have been busy. According to US-CERT, if you're connecting a new computer to the Internet, nowadays it can take only minutes for a hacker to exploit the security on some networks. See the Tech Tip for how to protect your new computer before connecting it to the Internet.

Some tips to keep your computer secure:

• Maintain up-to-date antivirus software. 
• Download software programs and updates directly from the vendor's website.
• Don't follow unsolicited links or open unsolicited e-mail messages (pdf).
• Use caution when visiting websites you don't trust. Ditto for downloading and installing programs.
• Protect your privacy and avoid social engineering and phishing attacks (when an attacker contacts you under false pretenses and tries to trick you into providing your private information).
• Sign up for cyber security alerts and cyber security tips.

And if the security of your computer has been compromised, see how to recover from a Trojan horse or virus (pdf), report a phishing site, or notify federal law enforcement if you're a victim of Internet fraud.

For more information on common online threats, protecting your privacy and maintaining your security, and reporting Internet fraud and Internet-related crime, visit USA.gov's FAQ and the Federal Citizen Information Center's publications.

Today Jane Goodall, famously known as the woman who lived with chimpanzees in Tanzania and noted conservationist, is lecturing at the Library of Congress on endangered species. Conservation efforts like Goodall’s were on my mind last weekend as I walked past endangered Galapagos Tortoises and Madagascar lemurs at a zoo. Seeing those animals made me curious about endangered species in the United States.

I learned that the U.S. currently has 1,320 endangered or threatened animal and plant species. An endangered species is in danger of extinction throughout all or a significant portion of its range, and a threatened species is likely to become endangered in the foreseeable future.

According to the U.S. Fish and Wildlife Service (FWS), the current rate of extinction is much higher now than in the past, mainly due to habitat loss. Other reasons are disease, pollution, the introduction of harmful nonnative species, and over-exploitation of wildlife for commercial purposes.

You can search for a specific species of plant or animal to find its status, or see the status of some of the more popular species.

A number of species have been removed from the endangered or threatened list. It’s chilling to me to see the species that are no longer on the list because they’re now extinct: the blue pike, the Santa Barbara song sparrow, and the Mariana mallard, to name a few.

Still, other species are no longer on the list because they’ve been saved by conservation efforts. The gray wolf, the Yellowstone grizzly bear, and, as GovGabber Jake noted, the bald eagle, are some of the success stories.

Learn more about endangered and threatened species from the National Oceanic and Atmospheric Administration and the U.S. Environmental Protection Agency. And consider buying Federal Duck Stamps, where 98 cents of every dollar go directly to buying or leasing wetland habitat for protection in the National Wildlife Refuge System.

What do you think about wildlife and plant conservation?

“There’s smoke coming from the Pentagon!” one of my coworkers shouted. I ran to his office window where we worked at the top of the Old Post Office Building in downtown Washington, DC, to witness black ribbons flowing from the Department of Defense building. This, after just watching the Internet’s news about the attack on the World Trade Centers that morning, September 11, 2001.

We were allowed to leave work—but I was at a loss as to how to get home since I had heard that the subway was closed. I had just moved from DC to a suburb in Maryland, and didn’t know an alternate way to get home. I ended up stuck on a gridlocked bus for four hours because I didn’t have another plan.

Are you prepared for a natural disaster, potential terrorist attack, or other major crisis? September is the sixth annual National Preparedness Month, sponsored by the U.S. Department of Homeland Security.

The companion website, Ready.gov, gives you tips on what to include in a basic emergency supply kit, and suggests ways to contact and regroup with family members in an emergency. It also offers information on a variety of emergency situations, such as influenza pandemics, wildfires, chemical threats, and winter storms, and recommends preparations for businesses as well.

Interactive features help you personalize a family emergency plan, and links take you to sign up for free emergency alerts from your local government. You also can follow Ready.gov on Twitter, or take the Readiness Quotient quiz.

USA.gov offers information on preparing for emergencies for specific groups, including people with disabilities, kids, and pets, and links to federal information on disasters and emergencies.

Since 9/11, I’ve maintained an emergency supply kit and made it a point to learn a variety of ways to get home. Do you have an emergency kit and plan?

I must admit that I had never heard of Juneteenth until I started working at USA.gov. In researching dates for the federal web portal, I noticed that the commemoration of Juneteenth popped up in a number of Library of Congress and Smithsonian webpages. I became intrigued to learn more, which I did. So I was especially excited to substitute for GovGab today, on the anniversary of Juneteenth.

Juneteenth—which is a combination of the words "June" and "nineteenth"—is a celebration to commemorate June 19, 1865, when Union soldiers finally arrived in Galveston, Texas, to spread the word that President Lincoln had issued the Emancipation Proclamation more than two years before. The Library of Congress says the reason for the delay was the fact that news traveled so slowly in those days.

As the news spread, former slaves celebrated with festive foods, music, dancing, singing, games, and stories. Juneteenth has been celebrated each year since 1865. In 1979, Texas became the first state to proclaim Emancipation Day (Juneteenth) an official state holiday. Today, more than half of the states in the U.S. officially observe Juneteenth each year. People celebrate with parades, festivals, and cookouts.

Would you like to find out where Juneteenth events are in your state? Visit your state on this map for a list of local events.

I'd love to hear from any of you who celebrate Juneteenth! Tell me how you commemorate this special day.

In the past when I'd come upon a work zone and have to slow down, I'd get as irked as any other driver. Like everyone else, I'm often in a hurry.

But after researching for this post last week, something changed in me. I learned some statistics that made me want to slow down in a work zone.

The Federal Highway Administration reports that every year, more than 40,000 people are seriously injured in work zone-related crashes, and more than 800 people are killed. Did you know that most of those injured or killed are drivers and passengers?

This is the 10th annual National Work Zone Awareness Week, which kicks off at the start of the construction season to attract national attention to drive carefully through highway construction and repair sites.

Most deaths and injuries in work zones are caused by rear-end collisions. Many collisions occur before the construction work zone begins, where lanes close and cars merge. Drivers cutting in at the last minute cause sudden stops, and inattentive drivers going too fast aren’t ready for traffic to slow or stop.

And most work zone accidents don't occur at night during a storm—they mostly occur in daylight, on a clear or cloudy weekday.

Some basic "Safety Tips to Live By":

• Pay Close Attention. Signs and work zone flaggers save lives.
• Don't Tailgate.
• Keep Up with the Traffic Flow.
• Minimize Distractions. Avoid changing radio stations and using a mobile phone while driving in a work zone.
• Be Patient. Remember that work zone crews are improving your future ride.
  

To help you be patient, check out a database where you can search for road construction projects in the U.S. and Canada. You'll finally know what that work zone you pass everyday is for, and when it's scheduled to be completed.

And for some fun: help name the National Work Zone Safety Information Clearinghouse mascot (voting closes at 10 AM EDT today).

Do you have any work zone stories to share?
