GNU/Linux and free software are a boon to a lot of businesses, and a thorn in the sides of others. Both the friends and enemies of Linux are realizing that Linux is important, and that it is here to stay. HP is leveraging Linux to try to return from the brink of financial ruin. As colleges and other schools around the country teeter on the verge of bankruptcy, many are moving to open source textbooks as a lower cost alternative. Free software is freeing people from the shakedown that is cable television. Finally, Microsoft has broken down and contributed code to a GPL version 3-licensed project. read more...

Fifty-six of the best open replacements for closed source, commercial web development and design tools...
As these tools mature, it's becoming more and more difficult to sort them into categories. Some blogging platforms are robust enough to build an entire site. Content management systems often have some features you usually find in Web app development frameworks, and text editors begin to look more and more like full integrated development environments (IDEs).

While that makes it tougher to organize our lists, it's good news for designers and developers. As Web tools offer more features, it makes Web professionals' jobs easier, and it opens up new opportunities for hobbyist and home users whose coding skills might not be as well developed.

NDSAD: an open source NetFlow probe

Up
vote
Down

Sometimes it is required to collect statistics on network traffic, e.g., for security purposes or for usage-based billing. One of the most preferred ways is to use a Cisco router that exports traffic data in a Netflow stream. Cisco routers are good. But what to do when dealing with a PC-router? The solution is to use a Netflow probe, a daemon that intercepts packets on a network interface of the router, captures statistics, and exports it in a stream of Netflow packets.

NDSAD (NetUP Data Stream Accounting Daemon) is a Netflow traffic probe. read more...

Open source ROI

This article is excerpted from the book Open Source for the Enterprise, which lists for about $23.
Some of the commercial companies promoting the ROI of Linux have also created studies showing that Linux costs less than the alternatives, but they use assumptions that apply to only a few companies.

For most uses of open source, there is no vendor preparing an ROI study. Even a specious ROI study can be adjusted with assumptions that match more closely the conditions at your company. Getting ROI correct is always a "do it yourself" proposition. With that in mind, let's discuss how you can determine the ROI of an open source project.

All three programs have automatic cell filling, which detects a pattern in cell data such as the days of the week or an incremental pattern in numbers, then uses the pattern to fill other cells when you drag on the lower right corner of the first cell. In Calc and KSpread, you can define fills and add them to the patterns that the program can detect -- a feature especially useful when creating templates. In addition, KSpread has a Series tool in the Insert menu which can be used to define numerical patterns.
