FreeNX: Linux “Terminal Server” Technology

Way back in “the day” I used Xwindows (X11) on both UNIX and VMS operating systems on “high end” (for the time) workstations and servers. It was a very cool client/server technology that displayed screens of sessions from one system on the screen of another. Though, for those of you that actually worked with it… do you remember that the “Client” and the “Server” seemed logically reversed? Yep. Got a grin out of you! Anyway, it was also SLOW. Very cool, but slow! X11 technology has been around for many years. However, now there is a “New X,” called, interestingly enough, “NX.”

The NX Protocol and Linux Terminal Server

“NX is a new technology that allows one to run remote X11 sessions across slow or low-bandwidth network connections. User experience with NX is one of excellent responsiveness. Users with previous remote X11 session experience are stunned by NX’s speed and its snappy application interaction. Moreover, NX also can connect to remote RDP and VNC sessions and offer big performance wins over TightVNC and rdesktop remote access. NX can do all of this from Linux, Mac OS X, Solaris and Windows workstations as well as from some types of PDA gadgets.”

Very small packets, very fast displays. It sounds like the IGA protocol and Citrix, doesn’t it? I am a Citrix Administrator and consultant, and I can tell you, it is a VERY HOT technology! So… what if you could have an Open Source version (FreeNX), and a fully supported commercial version, by a company that does BOTH? Well, here you go!

NoMachine.com: Commercial, Supported NX

“NoMachine NX is a Terminal Server and Remote Access solution based on a comprising set of enterprise class open source technologies. Thanks to the outstanding compression, session resilience and resource management developed on top of the X-Window system, and the integration with the powerful audio, printing and resource sharing capabilities of the Unix world, NoMachine NX makes it possible to run any graphical application on any operating system across any network connection as if you were sitting in front of your computer.”

Keep an eye on this one! It looks VERY COOL!

Geek Software of the Week: Express Burn

If you are a geek, you sometimes need to burn an ISO image to a CD. Say, you want to install Linux… you can download ISOs but you can’t just “copy” those ISO files to CDs!!! (Believe me, I know some that have actually tried that!) You need a CD burning tool! But tools like Nero Burning ROM aren’t free… and Nero has gotten huge and bloated with features that you don’t need, or want! So, how about a FREE CD burning tool?

Express Burn FREE CD Burning Software

Features:

  • Writes both data CDs (for files) and audio CDs (to be played in CD Players).
  • Records CD Recordable (CDR) and CD Re-recordable (CDRW) discs.
  • Support Jolliet and CDA formats.
  • Data CDs support multilevel folders and long file names.
  • Audio CDs are recorded with direct digital recording (so perfect audio quality is maintained).
  • For Audio CDs it supports wav, mp3, wma, au, aiff, ra, ogg, flac, aac and a number of other audio file formats.
  • Data CDs are fully ISO compliant with Joliet extension.
  • Includes command line operation for automation and integration with other programs.
  • Simple, easy to use interface for day-to-day operation.
  • Be sure to download and use the “freeware” edition.

    Google Desktop – Unsafe?

    I don’t like obtrusive doohickies anyway!

    Google Desktop Unsafe!

    “The nonprofit Electronic Frontier Foundation said a new feature added to Google Desktop on Feb. 9 is a serious privacy and security risk because of the way a user’s data is stored on Google’s servers.

    The new ‘Share Across Computers’ feature stores Web browsing history, Microsoft Office documents, PDF and text files on Google’s servers to allow a user to run remote searches from multiple computers, but, according to the EFF, this presents a lucrative target to malicious hackers.

    ‘[We urge] consumers not to use this feature, because it will make their personal data more vulnerable to subpoenas from the government and possibly private litigants, while providing a convenient one-stop-shop for hackers who’ve obtained a user’s Google password,’ the EFF said in a statement.”

    New Battery Technology

    Everything these days seem to run on batteries! Now, MIT has made a breakthrough in a new type of battery that could change everything!

    New Battery Technology

    “Joel E. Schindall, the Bernard Gordon Professor of Electrical Engineering and Computer Science (EECS) and associate director of the Laboratory for Electromagnetic and Electronic Systems; John G. Kassakian, EECS professor and director of LEES; and Ph.D. candidate Riccardo Signorelli are using nanotube structures to improve on an energy storage device called an ultracapacitor.

    Capacitors store energy as an electrical field, making them more efficient than standard batteries, which get their energy from chemical reactions. Ultracapacitors are capacitor-based storage cells that provide quick, massive bursts of instant energy. They are sometimes used in fuel-cell vehicles to provide an extra burst for accelerating into traffic and climbing hills.

    However, ultracapacitors need to be much larger than batteries to hold the same charge.

    The LEES invention would increase the storage capacity of existing commercial ultracapacitors by storing electrical fields at the atomic level.”
