Tech Tips
Josh's
  • Follow-up on the previous VNC tip: How to do it securely via SSL
    • VNC is not secure by default; entering passwords and transmitting data insecurely over an open wireless network, or any untrusted network for that matter, is unsafe and can potentially leave your passwords and data exposed to hackers, identity thieves, etc.
    • How-to for Mac OS X
      • easy instructions can be found here
      • no third-party software required; Mac OS X has SSH server and client functionality built in
    • How-to for Windows
      • SSH server software: OpenSSH via Cygwin (instructions can be found here)
    • Again, I recommend configuring your router to accept SSH connections through an IANA Unassigned port, since hackers may potentially look for open SSH ports (TCP port 22) to try to break into systems
Kyle's
  • (Waiting for iWork '08 before doing his tip.)
Anthony's
  • Things you didn't know Google could offer you
    • Google Docs & Spreadsheets
    • 1-800-GOOG-411
      • Josh mentioned another phone-based service (not from Google): TellMe (1-800-555-TELL) which has news (including tech news), sports, driving directions, movie descriptions and tickets, blackjack, and more—all for free
    • Google Notebook - make notes and Web clippings while browsing in Firefox
    • Google SketchUp - 3D modeling/CAD-type software
    • Kyle recommends avoiding Google Web Accelerator because it can cause problems with some sites (not to mention the privacy issues)
Software/Hardware/Site etc. Picks
Josh's
  • Adium - multi-service IM client for Mac
    • There is some disagreement even within the Adium development team on how Adium should be pronounced, although it's pronounced like the word "stadium" in the videos on the official site
    • Adium supports numerous services (AIM, Yahoo!, MSN/Live Chat, Google Talk, Jabber, ICQ, Gadu Gadu, and many more), is highly customizable and very Mac-like, with an intelligent Dock icon, Growl integration, and much more
  • Trillian - multi-service IM client for Windows
    • doesn't support as many IM services as Adium and Pidgin, but has a nice interface and has video support
    • also: Pidgin (formerly known as Gaim) - for Windows and Linux, uses the same engine that powers Adium
Anthony's
  • USB 2.0 vs Firewire 400 hard drives enclosures: Which one should I get? Which is faster?
    • FireWire 400, according to tests—in spite of the fact that the USB 2.0 specification of 480 Mbps indicates that USB should be faster
Kyle's
  • Best deal for speedsters: Intel Core 2 Quad Q6600, 2.4 GHz, 2x 4 MB cache, LGA775 socket, recently priced at $289 on zipzoomfly
  • Intel Core 2 Duo E6600, 2.4 GHz, 4 MB shared cache, LGA775, recently $223 on zipzoomfly
  • AMD Athlon 64 X2 6000+ Windsor, 3.0 GHz, 2x 1 MB cache, AM2 socket, recently $169 on mwave
  • Intel Pentium Dual Core E2160, 1.8 GHz, 1 MB cache, LGA775, recently $96 on newegg
  • AMD Athlon 64 X2 3800+ Windsor, 2.0 GHz, 2x 512 KB, AM2, recently $68 on zipzoomfly
Listener Questions
What is IPv6, and how does it differ from IPv4?
  • IPv6 is the next version of the Internet Protocol, and is already supported by major operating systems
  • One of the main advantages over IPv4 is the huge number of addresses IPv6 supports: an estimated 5,000 IP addresses per square micrometer of Earth's surface (far more than necessary for the foreseeable future, thus providing a lot of room for growth)
  • IPv4 addresses are much shorter and much easier to memorize, so it's much more practical to use it for LANs
  • See http://en.wikipedia.org/wiki/IP_address and http://en.wikipedia.org/wiki/IPv6 for more information
Log Out
Is there any way to disable the annoying nag message in Windows XP that incessantly prompts the user to restart after installing critical updates?
  • Yes, although of course it's recommended to restart since the security provided by the updates may not take full effect until after rebooting
  • If you want to disable it anyway, you can try Auto Reboot Remover from IntelliAdmin or these manual instructions
