| New camera chip could turn phones into 3D scanners |
Apr 06, 2015 - 8:22 AM - by TechSocial |
U.S. researchers have developed a camera chip that could give smartphones the ability to take 3D scans of everyday objects, a sought-after feature in the 3D-printing world. |
Engineers at the California Institute of Technology (Caltech) said their device is based on a cheap silicon chip less than 1 millimeter square and it can produce 3D scans with extremely fine resolution.
The chips could be incorporated into phones and the data could be sent to 3D printers to duplicate scanned objects, eliminating the need to use large desktop devices.
The device works by shining beams of light, which are perfectly aligned, on a targeted object. It then detects subtle differences in the light that is reflected back from that object. The differences help it build a digital 3D image of the target.
To shine the light, the device uses an array of tiny LIDAR (light detection and ranging) laser beam scanners. Useful for measuring distance, LIDAR elements have been used for years in applications such as navigation for driverless cars and robots.

| Expired Google certificate temporarily disrupts Gmail service |
Apr 06, 2015 - 8:13 AM - by TechSocial |
Google forgot to renew one of its TLS certificates, leading to service disruption Saturday for people using Gmail through third-party email clients. |
The problem was fixed in a matter of hours, but should serve as a reminder to online service operators that keeping track of digital certificate expiration dates is important and should be planned for in advance.
Some users reported Saturday on Twitter and other sites that email clients like Microsoft Outlook and OS X Mail were displaying certificate errors when trying to send email messages through smtp.gmail.com.

| Open-source Windows? The unthinkable is already happening, says Microsoft |
Apr 03, 2015 - 8:23 PM - by TechSocial |
However unlikely a future in which Microsoft makes Windows open source may sound, Microsoft has already taken considerable strides in that direction. |
But instead of allowing developers to make changes to Windows and other products, it’s Microsoft’s fingers at the keyboard.
According to Microsoft Technical Fellow Mark Russinovich, a future that includes an open-source Windows could happen. “It’s definitely possible,” Russinovich reportedly told an audience at the ChefCon conference in Santa Clara this week. “It’s a new Microsoft.”
“Every conversation you can imagine about what should we do with our software—open versus not-open versus services—has happened,” Russinovich added.
