Open Source City

LinCity looks like a great Linux clone of the traditional Maxis game, SimCity. Now in an updated form LinCity-NG now has an isometric 3D view similar to that found in SimCity 2000, arguably the best version of the classic game.

Hands-on Science Activities

The San Francisco Exploratorium has a great website with a number of hands-on science activites you can do at home. These projects and experiments have the potential to become great science fair projects with a little research and polishing. Check out the Exploratorium Hands-on Activites section for learning about everything from food to buliding your own telescope.

GPS Maps

I’ve had a bluetooth GPS for a few months now and have really enjoyed it. One of the more fun things I like to do is create virtual tracks of where I’ve been. One website that can help you do just that is GPS Visualizer.

GPS Visualizer allows you to upload NMEA GPS logs to their site and export maps in a variety of formats. One of the most compatible formats uses a Google Maps overlay. They also support the Google Earth overlay and KML formats and several static formats such as SVG and JPEG/PNG using a variety of map sources.

Subnetting

Subnetting is the art of dividing one network into many by use of a subnet mask. In my experience one of the most difficult things for networking students to master is subnetting. When they need some kind of new viewpoint on the subject I usually send them to LearnToSubnet.com. This site has been around for several years now and offers free mini-lectures on this important topic. All told there are several hours of video there and you may need to refer to some of the sections multiple times to gain a full understanding of subnetting but it is one of the better sites out there for this.

Deploying Windows XP

Backin August, 2004 I mentioned the XPCREATE utility which can be used to slipstream service packs and hotfixes into Windows XP installation CDs. With Windows XP continuing to age and hotfixes still accumulating there are even better tools availible to ease the installation process. The most widely recognized tool today is nLite. This program has a clean and easy to use interface that allows you to create deployment CDs for Windows XP that include all of the latest hostfixes plus craft an unattended installation disc or one with custom default settings. Previously creating discs such as these was only possible with a deep understanding of how Microsoft install CDs worked and writing a lot of INF files by hand. Even for simply getting patches onto your install CD nLite is a great option.

Calendar Server

WebCalendar is a highly configurable PHP/database based calendar package. You can set it up for use by either a single user or a group of users. It also operates a calendar server than can be viewed by any iCal-compliant application such as Mozilla Sunbird, Apple iCal, GNOME Evolution or RSS enabled applications such as Firefox, Thunderbird, RSSOwl or FeedDemon. Another one of the features I enjoy is tha ability to set email reminders. One of the surest ways of reminding me about something is via an email so this is a fantastic feature for me. If you’re looking for a calendar solution be sure to check out WebCalendar.

Stop Badware

Three powerful institutions have teemed up against so called “malware “spyware” and “badware”. StopBadware.org aims to be a clearinghouse for information about badware. Organized by Harvard Oxford and Consumer Reports the site is currently collecting user stories and technical reports in an effort to better understand the problems and programs associated with badware. Part of the problem in dealing with badware is that it’s hard to nail down exactly what qualifies as badware. These researchers hope to answer that question based on user input. Eventually the site will include access to this database of user reports about specific applications and behaviors associated with badware. Many listings of spyware have found themselves on the receiving end of a lawsuit from a listed company but hopes are that with the backing of Harvard Law School and actual reports from end users this site will be able to call out any company supporting badware without much fear.

I’m surprised this hasn’t received more coverage in the “geek” press (Digg, Slashdot, etc.) and expect StopBadware.org to become a significant player and information clearinghouse in the anti-badware arena.

Microphone Selection for Portable Recorders

For some time I’ve been keeping my eye out for a portable archival-quality audio recording device. This fall I finally purchased the recently released M-Audio Microtrack 24/96 and I’ve been thrilled with all this little recorder can do. I looked at similar products from Marantz and Roland but they didn’t meet my requirements as close as this.

One common accessory to these small recorders is a good microphone. Thanks to the folks at minidisc.org for putting together this great guide to microphones commonly used with small recording devices. As the saying goes “garbage in, garbage out” so a good microphone is key to getting a good recording. Of course this guide was originally written for MiniDisc recorders but the research should be valid for portable digital recorders as well.

As podcasts become more prevalent many people are finding that a good recorder and a good microphone are second only to content when it comes to podcasting to a large audience.

The End of an Era

On January 27, 2006 Western Union officially stopped sending telegrams. The fact that this was a non-event should tell you something about how important the telegram has become in our society but it wasn’t always that way. For many years the telegram was the only fast way to get a message transmitted over long distances. Indeed telegrams contributed much to our culture during the latter ninteenth and early twentieth centuries.

One of the contributions was the widespread use of code phrases and words to shorten a message. Today this may look something like “LOL” or “ROFL” in an instant message window but long before the invention of instant messaging telegraph companies and customers were abbreviating common messages with codes such as Western Union “92” code or “Wood’s 1864 Telegraphic Numerals”.

For more information on the history of the telegraph I suggest looking at “A Brief History of Telegrams” by the folks at retro-gram.com. You might also enjoy browsing some of the photographs at the British Science and Society Picture Library, which coincidentally has many other interesting historic science photographs, or reading about telegraph workers at the Norwegian Telecom Museum.

Crime may not pay but it sure is fun to watch

You may be surprised to know that I’m a fan of the US TV series “Cops“. After all, it’s not known as the most intellectually stimulating show but I do find it amusing to see what kind of trouble people can talk themselves into. “Really, I just pulled you over for a headlight that was out and in the end you’re going to prison because you told me I could search your car and I found a dozen guns and five pounds of drugs.” It’s also interesting to keep an eye on police tactics and see just how close they themselves can walk the line of illegal activity such as entrapment.

Along the same lines the website BaitCar.com has some fun videos you can watch. In case you didn’t know bait cars are cars that police agencies have rigged with video and sound and which usually can be remotely disabled. The departments put them out on the streets in the hopes that someone will steal them and they can get a car thief off the street. Now most of these thieves are not the brightes bulbs on the tree to begin with but how can you not laugh when they’re praying they’re not driving a bait car.
