Our replay of Charlie Schluting's excellent Networking 101 series continues with a two-part dissection of TCP. Understanding the ubiquitous TCP is key to troubleshooting networking communications.

It was only ever a matter of time before Toshiba stripped off and jumped in the rapidly crowding Netbook pool. Will the Ubuntu 8.04 driven NB100 make a splash?

My inability to do more-than-simple mathematics at times has really put a cramp in my computing style. In the case of OpenBSD and the $15 Laptop — the Compaq Armada 7770dmt — it has cost me 32 MB of RAM ever since I upgraded from 64 MB to the maximum 144 MB. The reason is that in some Compaq's OpenBSD will not address more than 16 MB of RAM without some intervention on the part of the user.

Carla Schroder says she just "kind of wandered into" her current life as a free software advocate and well-known IT journalist. "I don't have much in the way of formal education. But I've always been mechanically inclined - your classic ripping things apart and figuring out how they work. I think that makes open source a natural fit for me."

Matt Hartley at Datamation recently suggested promoting open source adoption -- using a very different venue. He suggests mall kiosks as a potentially effective way to spread the word about open source software, and how it can work for the average computer user. This is a fascinating idea. User groups could reach several different demographics, populations that might never have heard of Linux, never mind understand the joys (and trials) of using it.

Adobe has issued its second release candidate of Flash Player 10, which should be approaching the finish line. Developers have not only fixed a number of bugs, but added a few new features.

shd-tcp-tools provides a collection of tools for port forwarding, load balancing, and rate-limiting TCP connections.

We’re still working on this. There’s been a bunch of helpful feedback. We appreciate this. We think we’ve integrated the feedback into something that’s a good solution; different from out last version in both its essence and its presentation and content.

Cisco and VMware hook up in one of the oddest technical romances in recent history. What good can come of this?

T&A Lingerie says it runs Ubuntu Linux on servers and desktops. But is this a legitimate claim, or an attempt to trick geeks into looking at ladies in lingerie? Judge for yourself.

The Shuttleworth Foundation’s open philanthropy fellow, Mark Surman, will be moving to the Mozilla Foundation where he has been appointed executive director and will continue his work in open sourcing philanthropy.

Plenty of people say Ubuntu isn't ready for prime time. But what they really mean is "I don't want to learn a new operating system." Here's how I convinced my wife to overcome her fear of switching to Ubuntu. Take a look.

Things go wrong. Hard disks fail and whole servers crash. Luckily, many Linux-based distributions are available to help systems administrators handle minor catastrophes. We looked at four of the most portable, all of which fit on a 210MB mini CD -- SliTaz, Parted Magic, GParted, and RIPLinuX. Each of these distributions is easy to use -- just insert the CD or plug in the USB drive on which it's installed, then boot. Each gives you access to a variety of open source tools that you can use to manage disks, partitions, and files and perform diagnostics and network troubleshooting. These distributions provide most of the tools that you might need in an emergency situation.
