Firefox Hacks (Hacks)

Good bok for developers and admins alike Firefox Hacks is a great collection of information about the Mozilla Firefox browser. While almost anyone who has used Firefox would learn a great deal from reading this book, developers, admins, and advanced power users would benefit most from reading this. The book starts out nicely by going under the hood to look at internal settings, then turns to presentation aids and then to developer tools. I wish I'd had the book several months ago when I was doing more development! From code development the book moves into altering the browser look and feel, and finally into extension development. Although I may never do so, it's nice getting a guided look into areas I don't see on a day to day basis.

Meet Steve Martinez, cyber G-man.

Linux-Vserver on Debian Sarge

Linux-VServer allows you to create virtual private servers and security contexts which operate like a normal Linux server, but allow many independent servers to be run simultaneously in one box at full speed. All services, such as ssh, mail, Web, and databases, can be started on such a VPS, without modification, just like on any real server. Each virtual server has its own user account database and root password and doesn't interfere with other virtual servers

Senior citizen bloggers defy stereotypes

Web logs, more often the domain of alienated adolescents and middle-aged pundits, are gaining a foothold as a new leisure-time option for senior citizens.

Installing a Linux-2.6.14+initrd on Sarge (nodevfs anymore)

  • Debian Administration; By Jean-Chrstian de Rivaz (Posted by tuxchick on Nov 11, 2005 11:58 PM EDT)
  • Story Type: Tutorial; Groups: Debian
Until recently I used the default 2.6.8 kernel included into Sarge. When I tryed to install a vanilla 2.6.14 kernel I faced the "no devfs" problem. It's not that I forgot to turn on "devfs": "devfs" in not part of the Linux kernel anymore. The "udev" subsystem replace "devfs" and it's easy to install it into Sarge.

NewsForge presents free OpenOffice.org training videos

Massachusetts is trying to convert all computerized state documents to the open document format (odt). We think this is a fine idea. One concern that's been expressed about this move (at least by Microsoft) is that training employees to use OpenOffice.org 2.0 or other software that uses non-proprietary file formats (in place of Microsoft Office) will be time-consuming and costly. But what if basic OpenOffice.org training materials were available online for free? As a public service for Commonwealth of  Massachusetts employees (and everyone else), NewsForge is presenting -- absolutely free of charge -- 11 OpenOffice.org training videos as part of this article. They're excerpts from the video CD that comes with NewsForge Editor-in-Chief Robin 'Roblimo' Miller's upcoming book, Point& Click OpenOffice.org!, which will be available in December from all major booksellers. But we wanted you to have access to these videos now instead of waiting until the book is available, so here they are.

Automate Linux with cfengine

  • Enterprise Networking Planet; By Carla Schroder (Posted by tuxchick on Nov 11, 2005 11:11 PM EDT)
  • Story Type: Tutorial
As your Linux/Unix network grows, you're probably going to get tired of running around to individual machines to do updates and fixes, unless it's part of your fitness program. My ideal sysadmin scenario is rather like Dr. Evil's submarine lair: lounge about with a cat on my lap, occasionally pushing a button. Only I have no grand ambitions to conquer the world; I just don't like doing my modest chores the hard way. Cfengine (Configuration engine) is just the tool for streamlining hardworking system and network administrator's lives...Cfengine has two primary uses: Pushing out changes to all hosts on a network, regardless of operating system or hardware configuration. Automatically keeping all systems in a correct, stable state.

A network engineer at a Kansas City company says he's just as worried about threats to his company's network coming from inside the corporate walls than he is about any hacker busting through the perimeter.

[Ed.- Just like any business- the greatest security threats come from within, despite what corporate PR and Hollywood want you to believe.]

From the hip-hip hooray dept:

A Los Angeles District Court ordered three Web marketing companies to cease and desist an operation using the lure of free ringtones and browser updates to download spyware and adware to users' computers.

At the request of the Federal Trade Commission (FTC), the court also ordered a halt to the deceptive downloads of a marketing affiliate that helped spread malicious software by offering free background music for blogs.

What Microsoft Should Do

Henry Blodget writes: "(First, I should clarify my position regarding Microsoft: My position is not that Microsoft's web business sucks. It doesn't. Microsoft is either the third or fourth strongest web company on the planet. My position is that the common idea that Microsoft is going to do what it has done in many software businesses--come from behind, bury Google and Yahoo!, and rule the web--is ludicrous. Microsoft has been trying to come from behind on the web for a decade, and it is almost as far behind now as when it started. A few more years--or Microsoft Live, or AdCenter--is not going to change this.)"

[Well, it sure beats them having to innovate! - Ed]
