Oracle's going to require hands-on training - at an additional cost of thousands of dollars. The rule goes into effect on August 1, and cover certifications for Java Architect, Java Developer, Solaris System Administrator, and Solaris Security Administrator certifications. The courses will last between three and five days - and cost from $2,000 to nearly $4,000. You'll have to take them through Oracle University Training Center; Oracle Authorized Education Center or Authorized Education Partner; Oracle Academy and approved programs; and Oracle Workforce Development Program. You can still get certified under existing requirements through July 31. Hewlett-Packard wants to make hundreds of hires as it expands into new services. HP's primarily known as the world's biggest seller of PCs and printers. But it draws half its revenue from selling products and services to big business. Analysts say the company is heading into new markets. For example, it's expanding heavily into cloud computing. The company's listed about 150 positions on Dice. Most are in Texas and California, and include project managers, architects and cybersecurity experts. It's laid off 4 percent of its workforce, and its fourth quarter results weren't great. But Yahoo's got hundreds of job openings. Would you apply there? I sure would. Yahoo's a company in transition. Its online properties still attract 600 to 650 million unique visitors a month. And it's pushing to boost those through its purchase of Associated Content, which develops video and text information. Yahoo has 10 listings on Dice, but many of those cover multiple positions with a common job title. The company's looking for mobile engineers, developers, and quality assurance engineers. -- Mark Feffer
