Yahoo, Microsoft set for takeover battle

From CNN:

Yahoo Inc.’s first-quarter performance sets the scene for a bitter battle over Microsoft Corp.’s takeover bid.

By delivering earnings and revenue Tuesday that surpassed analysts’ estimates, Yahoo added credence to its board’s contention that the Sunnyvale-based company is poised for a dramatic turnaround that justifies a higher sales price than Microsoft’s initial bid of $44.6 billion, or $31 per share.

But neither the first-quarter results nor Yahoo’s outlook for the rest of the year may be compelling enough to cause Microsoft to sweeten its offer.

“This isn’t going to make Microsoft come and out offer $35,” predicted Canaccord Adams analyst Colin Gillis.

That leaves the rivals at an impasse, just as they have been since Microsoft stunned Yahoo with its unsolicited takeover attempt nearly three months ago.

Virtual reality helps autistic kids develop skills

From MSNBC:

A playmate named Sam, a talking dog named Buddy and an Israeli street leading to a Toys”R”Us store all have starring roles in a new generation of virtual reality games designed to teach basic safety and social skills to children diagnosed with autism.

For school-aged children with autism spectrum disorders, including Asperger’s syndrome, skills often taken for granted can be torturously difficult, whether staying within the confines of a yard, crossing a street or navigating the social norms of group playtime.

Aided by the observation that autistic children relate especially well to virtual reality and computer programs, an entire field of research has sprung up in the last 15 years.

Now vs. then: 1988 and 2008, A Tech Retrospective

I wasn’t sure if this was more a news item or a tip, but I’ll consider it a tip (actually, a recommended web site). PC World recently had an article comparing technology from 10 years ago with today.

Ever wax nostalgic about your first PC or cell phone? It’s easy to forgive your Tandy desktop or your Motorola portable for their limitations–after all, they were technological infants.

What we often forget, though, is how $%#@! expensive that crude neolithic junk was! So join us on a trip two decades back in technology’s history–and we bet that the next time you’re charged $895 for a small square of plastic and transistors, you’ll smile and say, “Wow, what a bargain!”

The article compares personal computers and components. It’s quite interesting!

geoGreeting

I was reading an article in the paper the other day about the Webby Awards, and one of the highlighted sites was geoGreeting. This is a site that let’s you write a message using pictures of buildings that look like letters (the PCIN.net image above for example). The creator of the site describes it in this way:

While working on a different Google Maps project, I noticed that a number of buildings looked like letters of the alphabet when viewed from above. This is the point where I should have just said ‘hmmm, good observation’ and gone on with my life. But I didn’t and that’s why this website is here.

Study Gives High Marks to U.S. Internet

From the New York Times:

Contradicting earlier studies, conventional wisdom and politicians’ rhetoric, European researchers say that the Internet infrastructure of the United States is one of the world’s best and getting better.

The Global Information Technology Report issued on Wednesday found that the United States now ranked fourth in the world behind just three European nations: Denmark, Sweden and Switzerland. Last year the United States was ranked seventh.

The study, which has been issued annually for the last seven years, is an effort to draw a more complete picture of national network readiness.

Clean Install Windows XP

There have been quite a bit of news recently about the Windows Vista upgrade DVD not really needing anything to upgrade from. You can do a clean install of Vista without putting in the product key, and then upgrade that installation. That talk has led to some talk about doing a clean install of XP, which led me to the website of Michael Stevens. He is a Microsoft MVP and has a good article about doing a clean install of Windows XP. The article is very through and has links to other resources that you might find helpful.

Say ‘cheese’: New tech measures a smile’s breadth

From USA Today:

The breadth of a smile can be measured by new technology from Japanese electronics and health care company Omron Corp.

The software technology, shown to reporters Thursday, scans a video image to detect faces. It can find up to 100 faces in an image, according to Yasushi Kawamoto of Omron.

“Okao Catch,” which means “face catch,” then analyzes the curves of the lips, eye movement and other facial characteristics to decide how much a person is smiling using data collected from a million people and their smiles, he said.

In a demonstration, a camcorder took videos of journalists covering the announcement. Percentage numbers indicating how much each person was smiling popped up in bold blue letters next to their faces on a monitor, flashing higher or lower as their expressions changed.

The numbers ranged as high as 89% for a person who was grinning, while a somber face registered 0%.

Where Did All the Girl Geeks Go?

From eWeek:

A professor says he has only one girl in a computer science major class in 2008, down from 40 percent in 2000. What happened? eWEEK gets field experts to weigh in.

While women hold 51 percent of professional jobs in the United States, they make up only 26 percent of the IT work force, according to the National Center for Women & Information Technology. Furthermore, fewer women worked in IT in 2008 than in 2000.

But the loss of women in the technology field begins long before they reach the professional level. The proportion of CS (computer science) bachelor’s degrees awarded to women has fallen from 36 to 21 percent between 1983 and 2006.

U.S. Adults Wary Of Web-Use Tracking

From InformationWeek:

A majority of U.S. adults are uncomfortable with Web sites using a person’s online activity to deliver customized content, a study released Thursday showed.

However, Harris Interactive found that people became more comfortable after they were presented with Web-site privacy and security policies recommended by the Federal Trade Commission.

Based on a nationwide survey of more than 2,500 U.S. adults, the study found that six in 10 respondents were skeptical when Web sites like those from Google, Yahoo, and Microsoft used visitors’ online activity to tailor advertisements or content based on their hobbies or interests. A quarter of the respondents were “not at all comfortable,” and 34% were “not very comfortable.”

Bounce Flash - Digital Photography Tip of the Week

Photographing people indoors often requires the use of flash for added light. Direct, on camera flash however often results in multiple problems, red eye, washed out or overexposed subjects and of course, harsh, unflattering light.

If you use the flash built in to your camera, you don’t have many options. However, if you use an external flash you can change the small, direct light source of your flash head to a large diffuse source by bouncing the flash off of the ceiling.

Most external flash units sold today have heads that swivel and tilt for directing the flash. Directing the flash at the ceiling makes the ceiling your lights source. In my tip Quality of Light and the Size of Your Light Source I talked about how the the size of your light source affects the quality of light, larger generally being considered better. In this case, the light reflecting off of the ceiling is significantly larger than your flash head. The resulting light on your subject is softer, shadows are not as harsh and the lighting is more even throughout the subject area.

To effectively use bounce flash, you need a ceiling that is not too high. The higher the ceiling, the higher the light loss (refer back to my tip on flash to subject distance). If the ceiling is textured your light will be more diffuse than if it is not. Bouncing your flash off of a coloured ceiling will introduce that colour into your photo so using this technique with white ceilings works best, however, ceilings with a slight warm tint may add a nice warm tone to your image. Your flash should be directed at about 45 degrees to the ceiling though the distance to your subject will determine the actual angle you may need.

Finally, use your histogram or image review on your camera. If you find your images are a little dark your flash may not have enough power to effectively bounce off the ceiling though you can increase your ISO to negate that effect.

The two photos below are images of my niece. The photo on the left was shot direct with flash. The flash was mounted on a bracket above the camera to help eliminate red eye and direct any shadows down and behind her. As you can see, the lighting is flat and unflattering. The image on the right was shot with the same set up but with the flash pointed toward the ceiling at about a 45 degree angle. As you can see the shadows are softer, skin tones are more appealing and she has gained a little bit of warmth compared to the first shot.

Being able to control your light is one of the basic steps to better photography.

Until next time, happy shooting.
