Security News: (via @SteveStyffe) @SGgrc Have you seen this? Google abandons plans to reduce SSL handshake latency.

Apple: About Java for OS X Lion 2012-003 "This Java security update removes the most common variants of the Flashback malware. This update also configures the Java web plug-in to disable the automatic execution of Java applets. Users may re-enable automatic execution of Java applets using the Java Preferences application. If the Java web plug-in detects that no applets have been run for an extended period of time it will again disable Java applets." Java for OS X Lion 2012-003 delivers Java SE 6 version 1.6.0_31 and supersedes all previous versions of Java for OS X Lion. This update is recommended for all Mac users with Java installed.

Errata: (@robertdwalker) @SGgrc OS X 10.7 did significantly improve ASLR. And, 10.8 improves it even further. You misstated that on SN.

Twitterverse: (@TechJeeper - Code Dean in Lansing, Michigan) @SGgrc "False Start's sad demise..." Wasn't this what provide a major advantage for SPDY? (@SimonZerafa) @SGgrc Is your installed JavaVM buggy and exploitable? :-) -> (@SimonZerafa) @SGgrc If you didn't go looking for it, don't install it; If you installed it, keep it updated; If you don't need it, uninstall it. (@enekob - Eneko Bilbao, Australia) @SGgrc re iOS encryption: Took your advice, upgraded to alphanum PIN. When changed does it re-encrypt the file system? Was very fast if so?!

$59/year per computer - Unlimited ($5/mo) Win/Mac/iOS/Android/Blackberry (Advanced features are currently Windows only) PIE? Can Carbonite employees see my backed up files? Access to your backed up files is protected by your encryption key which is kept strictly confidential. Unless you choose to manage your own encryption key (see below), a limited number of Carbonite employees are able to access backed up files in order to assist with data recovery if needed. However, they will do so only after obtaining your consent. If you are subject to industry regulations that require no one outside your organization have access to your backed up files (e.g. HIPAA regulations), Carbonite provides you with the option to manage the sole copy of your encryption key. If you choose this option, features such as Anytime Anywhere Access will be unavailable to you. Also, note that if you lose the sole copy of your encryption key, there will be no way for Carbonite to restore your backed up files. For these reasons, Carbonite recommends, and the majority of our customers choose, to have Carbonite manage their encryption keys.

Share folders instantly in web ShareRooms w / RSS Efficient Versioning: "SpiderOak keeps historical versions of every file. This is an extremely important safety feature in a backup application. Consider this scenario: You accidently save over your thesis paper with a different document. The easy solution is just go to your backup software and retrieve the old version, except what if you don't notice for a few days? If your backup software doesn't keep historical versions, it will save the new (wrong!) version of your thesis into your next backup, making recovery impossible.

SpiderOak's historical versions are space efficient. Even though your historical versions are encrypted and only stored on the server, SpiderOak detects the similarity between those historical versions and your new versions - only saving the parts that actually changed." HORRIBLE iTunes Store Reviews SpiderOak Promo Code: "Spring"
