How Do You Sync & Manage Your Home Directories?
digitalderbs writes “A problem plaguing most people with multiple computers is the arduous task of synchronizing files between them: documents, pictures, code, or data. Everyone seems to have their own strategies, whether they involve USB drives, emailed attachments, rsync, or a distributed management system, all of which have varying degrees of success in implementing fast synchronization, interoperability, redundancy and versioning, and encryption. Myself, I’ve used unison for file synchronization and rsnapshot for backups between two Linux servers and a Mac OS X laptop. I’ve recently considered adding some sophistication by implementing a version control system like subversion, git, or bazaar, but have found some shortcomings in automating commits and pushing updates to all systems. What system do you use to manage your home directories, and how have they worked for you for managing small files (e.g. dot configs) and large (gigabyte binaries of data) together?”

Best Handset For Freedom?
Father Thomas Dowd writes “The pictures we are seeing of Iran are being captured on cell phones and the text is being twittered over SMS. Still, the government has some control over the networks, and we are all familiar with fears of wiretap technologies to spy on users. If the cell phone is the new tool of freedom, what would the best ‘freedom handset’ contain? I’m thinking of a device with an open OS, where each phone could be a router for encrypted messages passed through Bluetooth/WiFi/whatever, thereby totally bypassing physical infrastructures when necessary. Of course, some sort of plausible deniability encryption a la Truecrypt would also be good, in case the secret police catch you with your phone. What else might we need?”

On encryption and why it’s overrated
Data encryption may not be the right answer anymore. Does distributed data storage make for a more secure enterprise?

DRM Group Set To Phase Out "Analog Hole"
eldavojohn writes “In yet another bid to make your life a little more annoying, our DRM overlords at the AACS Licensing Authority have released a new AACS Adopter Agreement. The riveting, 188-page PDF will inform you that — in the name of Digital Rights Management — there will be new limitations set on devices that decrypt Blu-Ray discs. HDMI already has the awesome encryption of HDCP between the device and the display unit. But Blu-Ray still has the Achilles heel of analog players that allow someone to merely re-encode the analog signal back to an unencrypted digital format. So if you have an analog HDTV, hang on to those analog decoders and hope they never break; by 2013 you won’t be able to buy a new one. Ars points out the inherent stupidity in this charade: ‘Particularly puzzling is the fact that plugging the so-called “analog hole” won’t stop direct digital ripping, enabled by software such as AnyDVD HD. And even the MPAA itself recommends using a camcorder pointed at a TV as a way to make fair use copies, creating another analog hole.’ And so the cat and mouse game continues. On that subject, DVD Jon’s legit company just brought out a billboard ad for his product doubleTwist next to Apple’s San Fransisco store. It reads, ‘The Cure for iPhone Envy. Your iTunes library on any device. In seconds.’ So while he’s busy taunting Apple, I’m certain there are others who might have some free time to look at Blu-Ray and the ‘uncrackable’ AACS.”

Apple’s WWDC Unveils iPhone 3.0, OpenCL, Laptop Updates, and More
Lots of big news from WWDC today including updates to almost all of Apple’s laptops. They added a 13-inch version to the MacBook Pro line, updated the MacBook Air, and added a few new ports to some of the machines including an SD slot and firewire 800 port. Software updates saw Safari 4 launched, OS X updates including threading changes, Exchange support to mail, calendar, and address book, and OpenCL a new open graphics standard. The iPhone got quite a bit of love in 3.0, much of it just confirming older news. Cut, copy, and paste, shake to undo, developer APIs, Cocoa Touch support for text, landscape mode updates, spotlight, and MMS all made the bullet list. You will now also be able to rent and purchase movies directly from your iPhone. Other new features in 3.0 include the much debated tethering ability, allowing you to use your iPhone as a cellular modem (unfortunately there was no mention of AT&T actually supporting this feature, a wonder there wasn’t a riot), integrated TomTom GPS navigation, and game features galore. New functionality also allows you to locate your iPhone via MobileMe, play a sound to help you locate it (regardless if it is set to silent), and even wipe your data remotely. The New iPhone hardware updates, “3GS”, adds a 3 megapixel auto-focus camera, voice interfaces, twice the processing power, and hardware encryption. The 3GS comes in 16GB (9) and 32GB (9), pushing the 3G (which they are keeping on the market) to . Lots of other small updates amidst the bustle, looks like another successful WWDC.

Ten Applications That Changed Computing
bfire writes “The term ‘killer app’ gets tossed around quite liberally these days. Nearly every piece of software released seems to be pitched as having the potential to send shockwaves throughout the IT world. In reality, there have been precious few applications which have truly changed the computing industry over the years. This article lists some of the top ten true killer apps that changed computing, from Phil Zimmermann’s gold standard in encryption, PGP, to Dr Solomon’s groundbreaking anti-virus toolkit, to Mitch Kapor who took the idea of VisiCalc for Apple and created Lotus 1-2-3 for DOS.” Typical for top-10 lists, the choices seem pretty arbitrary — what changed your corner of the computing world?

Flaw Made Public In OpenSSH Encryption
alimo20 writes “Researchers at the Royal Holloway, University of London have discovered a flaw in Version 4.7 of OpenSSH on Debian/GNU Linux. According to ISG lead professor Kenny Patterson, an attacker has a 2^{-18} (that is, one in 262,144) chance of success. Patterson tells that this is more significant than past discoveries because ‘This is a design flaw in OpenSSH. The other vulnerabilities have been more about coding errors.’ The vulnerability is possible by a man-in-the-middle intercepting blocks of encrypted material as it passes. The attacker then re-transmits the data back to the server and counts the number of bytes before the server to throws error messages and disconnects the attacker. Using this information, the attacker can work backwards to figure out the first 4 bytes of data before encryption. ‘The attack relies on flaws in the RFC (Request for Comments) internet standards that define SSH, said Patterson. … Patterson said that he did not believe this flaw had been exploited in the wild, and that to deduce a message of appreciable length could take days.’”
