Infiniti debuts breakthrough engine technology in new QX50

Jonathan Gitlin The new Infiniti QX50 might not seem the most natural fodder for these pages, but its engine surely is. Just introduced to the world at the Los Angeles Auto Show, the crossover is powered by the world’s first production variable-compression ratio engine. It’s a 2.0L turbocharged four-cylinder called the VC-Turbo, and it represents a huge leap forward for internal combustion engine technology. By altering the distance that the piston head travels within its cylinder, the VC-Turbo can operate with a compression ratio as low as 8:1 (for maximum performance) or as high as 14:1 (for maximum efficiency). The engine is as powerful as the older naturally aspirated 3.5L VQ V6 in the previous QX50 and makes more torque, but it’s also smaller, lighter, and a lot more fuel-efficient. It can even switch between the Atkinson and regular combustion cycles. Read 5 remaining paragraphs | Comments

Man Hacks Jail Computer Network To Get Inmate Released Early

An anonymous reader writes: A Michigan man pleaded guilty last week to hacking the computer network of the Washtenaw County Jail, where he modified inmate records in an attempt to have an inmate released early. To breach the jail’s network, the attacker used only spear-phishing emails and telephone social engineering. The man called jail employees and posed as local IT staffers, tricking some into accessing a website, and downloading and installing malware under the guise of a jail system upgrade. Once the man (Konrads Voits) had access to this data, investigators said he accessed the XJail system, searched and accessed the records of several inmates, and modified at least one entry “in an effort to get that inmate released early.” Jail employees noticed the modification right away and alerted the FBI. The man as arrested a month later and is now awaiting sentencing (maximum 10 years and a fine of up to $250, 000). Read more of this story at Slashdot.
