Well, some thoughts of mine in all the mess...

Firstly, excellent wireless card! Drivers, they always make a mess.

Circuitry 101: How to Hook Up LEDs

The direct url for this guide is: http://tutorial.lsdiodes.com Below we've created a very basic guide to help people unfamiliar with circuits get their LEDs up and running without blowing them out and wasting all their money. IT IS VERY BASIC!! Current is hardly ever mentioned, not because it's not important, but because we've found it makes things confusing when trying to teach people about this sort of thing. If we've done a bad job explaining things or if you have a question this doesn't answer, use the contact form at the bottom of this page to let us know what's up. There's two basic types of circuits: Series and Parallel.

Series or "How do I power lots of LEDs off a higher voltage source?"

When LEDs are placed in a series, the voltage is dispersed between the LEDs, meaning less voltage goes to each LED. This can be very useful. For example, if a 12 volt adapter were powering one LED, there'd be 12V going through that LED which is way too much for any LED to handle and would result in a rather unpleasant burning smell. However, if you take that same 12V power source and put 4 LEDs in series, there would be 3V going to each LED and (assuming the LEDs are made to run off 3V) each would be powered and just dandy. Check out this illustration: It's important to notice how the LEDs are positioned: (-) (+), (-) (+), etc. making sure that the end (-) connects to the (-) wire and the end (+) connects to the (+) wire, if any LEDs are backwards nothing bad will happen, they just won't turn on. If three LEDs were in series with a 12V source, each would receive 4V, if six were in series, each would receive 2V, etc. "But what if I have four LEDs powered from a 12V source and I want each to receive less than than 3V/ea?" This is where the little 'Resistor(s)' squiggly comes in. By adding a resistor it's possible to tone down the amount of voltage each receives. To find out what value resistor you should use, use an led calculator such as this one . Go to the middle form where it says 'LEDs in series' and simply type in your power sources' voltage, the LEDs' voltage you'd like and the LEDs current capability (use 20mA.) It then tells you what ohmage resistor to stick in the circuit.

Parallel or "How d o I power lots of LEDs off a lower voltage source?"

Let's say you wanted to power three of your brand new LEDs off a 3V battery pack (two 1.5V AA's in series, make sense?) you found lying around. If you were to series the three LEDs there'd be 1V going to each (3 Volts / 3 LEDs = 1V for each LED). That's not enough to power your LEDs! You want them to have the full 3V going to each. Here's how: How this works is that while every LED receives the same amount of voltage, the current of the source is dispersed between the LEDs. What this means for you is that you have 20 LEDs paralleled off a battery, it's going to drain the battery a lot quicker than if you only had 2 LEDs in parallel. If you're paralleling off a wall adapter, for instance though, the source can constantly renew itself so you can essentially parallel as many as you'd like without fear of draining the wall ;P. To use resistors in a parallel circuit, say if you'd like each LED above to receive 2.5V instead of 3V, use an LED calculator (make sure you're in the parallel section) to find the right ohmage and then stick it somewhere in the circuit! "Why do the LEDs have to be the same color?" If you mix colors, say if you paralleled a red (~2.3V) and two blue (~3.5V), the blue LEDs would not light. Why's this? Because the electricity is going to take the easiest path it can to complete the circuit and in this scenario the red LED requires less energy, leaving the two blue unpowered and lonely. To fix this you would need to stick a resistor onto the leg of each LED to 'equalize' all of the LEDs. Note illustration: To find the resistor you'd need for each LED, use the 'Single LED' portion of an LED calculator , type in the supply voltage, LED's voltage and 20mA for each LED and there you go. Now each LED will turn on and each will receive it's desired amount of power. Thanks to Mike Moorrees for pointing this out, "The resistors act like 'shocks' in a car, they give the power source some 'squish' and let each LED find its happy place (forward voltage)."

ClarkConnect | fsckin w/ linux

ClarkConnect Clark Connect Logois a BEAST - in a good way. It’s really hungry for a faster processor than I can throw at it. The list of features really blow everything out of the water. It’s not just a router or firewall platform, it’s like someone asked themselves a question: “What is EVERYTHING a small office could EVER need in a networking server?” ClarkConnect provides three different robust VPN connectivity solutions using IPSec, PPTP, OpenVPN, along with web proxy and web filtering. Additionally, it provides an SSH server, Quality of Service (QoS) filtering for common P2P applications, Intrusion Detection, and much, much more including email server, file, print, database and web serving. Not to mention a fairly comprehensive group ware suite, which has calendar, contact, tasks lists, and provides a paid option for using Microsoft Outlook Connector to allow everything to go right into Microsoft Office Outlook.

ClarkConnect is certainly a jack of all trades. Doing everything is great, but how well does ClarkConnect do it? On the testbed, installation was easy, and had an informative installation progress screen. The first time running through the installer, there was a problem with not having enough disk space. After rebooting and trying again, I chose to utilize Disk Druid, a partitioning program - instead of the auto-partition mode. Everything worked just fine after that. I believe the problem lies with the testbed - 1GB of space is not alot to work with, but fortunately they provide a manual partitioning method. It also prompts to create a GRUB (bootup) password, so that if the device is physically compromised, it would be more difficult for someone to maliciously (or accidentally) make changes to the system.

Configuration was an overall negative experience. It got confusing, not to mention frustrating. A small business owner who doesn’t know much about networking or computers, would be best to consider hiring a professional to do the initial installation, or paying for a yearly support contract from the vendor, or for a single incident. An interesting feature ClarkConnect leverages very well during configuration stages is a graphical interface to the system. Every other firewall reviewed here either has a very sparse text-mode or console configuration. ClarkConnect wants to make it easier. Just point and click to configure the system, which is nice - but it does not contain all of the features as the text-mode configuration tool which is also provided.

The Web Graphical Interface is easy to use. Items are categorized in a logical fashion and it doesn’t take much hunting to find something you want, if you don’t know where exactly it is in the menu. Style-wise, ClarkConnect is the only option in this roundup that provides a theme switcher - it is possible to use a very slick, visually appealing interface, or with a few clicks, just change to another theme which is less eye-candy, but probably more familiar to most people who have configured a wireless router in the past.

Many companies, like ClarkConnect, release a “community” version as well as a paid version which includes more features and support options, add-ons such as email and virus scanning is available on a subscription basis, and with so many features to start out with you might not need anything else to help to run a small business.

For some time I have gutsy 7.10 installed on my eee... should I go the 8.04 way?

To upgrade or not to upgrade all works well for me now - compiz, overclocking... now here comes along a kernel upgrade and things just stop.. I thnk I'll take the plunge!
