Suburban high schools in Arlington County, Va., are using computers to record and try to remedy the problem of truancy. Unexplained absences are recorded in the machine, and each night the computer telephones the student's home and, using a human voice, demands a written excuse for the absence.

Re "Unless Teachers Get Involved, Wiring Schools Just Enriches Computer Makers," Opinion, Aug. 10: Larry Cuban is correct that "anyone justifying the purchase and use of computers on grounds that all students will learn more, better and faster is lying." Computers are being used by corporations to influence school bureaucrats to spend on technology that is touted as having the answer to teaching kids. Through experience in the public school classroom, I know that computers are not the answer to literacy.

Caltech researchers have produced the most sophisticated DNA-based computer yet, a wet chemistry system that can calculate the square roots of numbers as high as 15. The system is composed of 74 strands of DNA that make up 12 logic gates comparable to those in a silicon-based computer, the researchers reported Thursday in the journal Science. But the system operates a little more slowly than a conventional computer: It takes as much as 10 hours to obtain each result. The new findings mark a major change in the direction of DNA-based computing, which researchers have been working on for two decades.

Steven Hackel has spent most of the last two decades bringing old California into the modern age. He's an expert in the baptism, marriage and burial records from the days of Spanish and Mexican rule. With a team of colleagues at the Huntington Library, Art Collections and Botanical Gardens, he's taken the information written down in the looping, 200-year-old handwriting of church scribes and created a computer database. So when Hackel heard this month about the discovery of dozens of bodies during a construction project on the site of Los Angeles' original cemetery, he started tapping on his keyboard.

NEW YORK - Federal prosecutors said they had foiled an international cyber-crime ring that targeted bank accounts in the U.S. and around the globe. The criminal charges, disclosed Wednesday, highlight the vulnerabilities of online consumer banking, which has become more popular in the digital age. It also comes just months after most every major U.S. bank suffered a relentless round of online attacks by Middle Eastern hackers. In the case unveiled Wednesday, three men - a Russian, a Latvian and a Romanian - allegedly created and spread a virus they called "Gozi" that infected more than 1 million computers around the globe, including at least 40,000 in the United States.

PHILADELPHIA — In ancient Greece, priests gathered at the Temple of Apollo on Mount Parnassus, the better to interpret the deity-inspired prophecies of Pythia, the Oracle of Delphi. Google Inc., for all its omnipresence, is no deity, yet legions practice search-engine optimization in an effort to divine the secret algorithms that move certain websites to the top of an online search. Now comes candidate optimization, essentially the same idea applied to job seekers, with services that help them tweak their resumes so they end up at the top of a list generated by a company's computerized talent-management system.
