Ask Slashdot: Free/Open Deduplication? 5

Submitted by

ltjohhed writes "We've been using deduplication products, for backup purposes, at my company for a couple of years now (DataDomain, NetApp etc). Although they've fully satisfied the customer needs in terms of functionality, they don't come across cheap — whatever the brand.
So we went looking for some free dedup. software. OpenSolaris, using ZFS dedup, was there first that came to mind, but OpenSolaris' future doesn't look all that bright. Another possibility might be utilizing LessFS, if it's fully ready.
What are the slashdotters favourite dedup flavour?
Is there any free dedup software out there that is ready customer deployment?"

Securing Android for the Enterprise->

Submitted by Orome1
Orome1 writes "While many companies use IPsec for secure remote access to their networks, no integrated IPsec VPN client is available on Android. Apple has already fixed this shortcoming in iOS, in part, because it wanted make the iPhone attractive for businesses. The Android operating system doesn’t just lack an integrated IPsec VPN client, it also makes installing and configuring third-party VPN software quite complicated. IPsec VPN clients have to be integrated into the kernel of each device, and the client software has to be installed specifically for a memory area. This means that the firmware of each Android smartphone or tablet has to be modified accordingly. Until a “real” IPsec VPN client is available, Android users can use their devices’ integrated VPN clients based on PPTP or L2TP, which is deployed over IPsec. A “real” IPsec VPN connection, however, is more secure because it encrypts data prior to authentication."

Medical Imaging with a Hacked LCD Projector->

Submitted by Anonymous Coward
An anonymous reader writes "Grad students at UC Irvine have built a spatial frequency domain imaging system using parts from a cheap LCD projector and a digital camera. The system can be used to check the level of bruising or oxygenation in layers of tissue that aren't visible to the naked eye, according to an article in Chemical and Engineering News. An accompanying video shows the series of patterned pulses that the improvised imaging system makes in order to read hemoglobin and fat levels below the surface of the skin. A more sophisticated version of the imaging system is being commercialized by a startup within UC Irvine, called Modulated Imaging. The article and video also describe infrared brain scanners that can non-invasively check for brain bleeds, and multiphoton microscopes that produce stunning images of live skin cells."

Are engineers natural libertarians or technocrats?->

Submitted by
uctpjac
uctpjac writes "This openDemocracy article uses Scott Adams' presidential bid to argue that however much engineers — especially Silicon Valley types — like to think that they're libertarians, they are in fact much more likely to be control-freak technocrats. Is this a fair account? Has the author wrongly read Dilbert, or wrongly interpreted the relationship between the engineering mindset and Adams' representation of it in the cartoon strip?"
