Last but not least, Linux support arrives for Chrome Remote Desktop

After pushing Chrome Remote Desktop to mobile, Google has finally announced official beta Linux support for its remote access and administration product. Earlier this year, Chrome Remote Desktop support was extended from Windows and OS X to Android, allowing users of the extension to get remote access to their Windows, Mac, and Linux desktops from the Chrome browser. But while Google promised that iOS support would come later this year, at the time there was no mention of equivalent support for remote access from a Linux machine.

The main draw of the Fidelys is its “military grade” iris recognition technology, which avoids the need for vulnerable, inconvenient, hard to remember passwords, says IriTech. By visually verifying one’s iris, the technology can […]

5 reasons why software bugs still plague us

Another month, another few dozen patches to install -- it's never-ending. It's frustrating. Software coding tools supposedly have security built in by default. We have "safe" programming languages. We have programmers using SDL (security development lifecycle) coding tools and techniques. We have operating systems with more secure defaults and vendors that fuzz and attack their own software with a vengeance to find holes. We have companies spending billions of dollars to eliminate software bugs.

Android Candy: Repix, Not Just Another Photo App

Apps like Instagram have made photo filters commonplace. I actually don't mind the vintage look for quick cell-phone snapshots, but a filter can do only so much. At first glance, Repix is another one of those "make your photo cool" apps that does little more than add a border and change saturation levels.

Is making your product free and open source crazy talk?

Making money from open source. To many in the corporate world, that seems like a contradiction in terms. How are you supposed to make money from something that you give away? they ask. It can be done. A number of companies, large and small, have done quite well in the open source space over the years.

Raspberry Pi Model B+ adds USB ports, expansion pins

The newly released Raspberry Pi Model B+ has the same CPU, memory, and $35 price, plus a new 40-pin GPIO header, two more USB ports, and a microSD slot. Considering all the competition from open-spec hacker boards like the Odroid and BeagleBone Black, not to mention Pi clones like the Banana Pi, the non-profit Raspberry Pi Foundation was overdue for an update to the world’s most popular single board computer. To be sure, “this isn’t a ‘Raspberry Pi 2?,” as Eben Upton and the Pi gang note in today’s announcement of the Pi Model B+. The update uses the same aging, ARM11-based Broadcom BCM2835 processor and 512MB of RAM as the Pi Model B, disappointing those looking for a Cortex-something update, but also maintains perfect software compatibility with Raspbian and existing Linux distros and applications.

Contacts and events everywhere - successful syncing between thunderbird and android with Baikal

Contacts and events everywhere - successful syncing between thunderbird and android with Baikal I got a new Android phone lately and was wondering how to handle my life. New phone, new chances, new life ;-) I have a lots of contacts. I used to store addresses in an openLDAP server, but I found these hard to manage especially since Ubuntu 14.04 does not ship "luma" anymore! I used to run radicale, but I did not manage to fix my sync-performance issues.

When "Free" Can Suck

"I'm sorry there kiddo. You can't watch a lot of videos or use your school's website because they depends on Flash. I'm also sorry that you can't play on miniclip.com or use some of your apps. Java doesn't work on your computer. But hey...ain't using Linux great anyway? Make sure to tell all your friends how great Linux is."

Google's act of stripping Java support from Chrome severely cripples that browser. What they intend to replace it with still remains to be seen. Is Chrome following Apples lead in refusing to include Flash? At first blush, it would certainly seem so.
