In 2003, San Francisco launched a $35 million pilot program to replace approximately 23,000 mechanical parking meters with electronic units that boasted tamper resistance, payment via smart card, auditing capabilities, and an estimated $30 million annually in fare collection revenue. Other major cities, including Atlanta, Boston, Chicago, Los Angeles, New York, Philadelphia, Portland, and San Diego, have made similar moves.

How to Easily Delete Computer Viruses Scientific American presents Tech Talker by Quick & Dirty Tips. Scientific American and Quick & Dirty Tips are both Macmillan companies. This is the second part of a series on computer viruses. And if you haven’t listened to the first one, go check out Anatomy of a Virus now, because what I’m about to say will make a whole lot more sense if you do! In my last episode, I mentioned that when you suspect you have a virus, the best fix is to turn off your computer completely. If the power to your computer is off, the virus can’t do any damage. Custom Single Key Shortcuts in Firefox using KeyConfig - Sridhar Katakam Keyconfig is a fantastic add-on for Firefox that lets you set custom keyboard shortcuts for every possible action/task in Firefox incl. launching bookmarklets. In this article I share how I set single key shortcuts like ‘z’ for going back ‘x’ for going forward ‘a’ to switch to left tab ‘s’ to switch to right tab ‘t’ to open a new tab ‘c’ for closing the current tab ‘r’ to refresh ‘i’ to start inspecting webpage elements with Firebug ‘u’ to copy URL of the current tab ‘l’ to focus address bar ‘d’ to bookmark in Delicious ‘v’ to view source ‘p’ to open Page Info window With these and a few other add-ons like Search Keys I fly in Firefox with keyboard, not point and click. Most of these shortcuts were what Opera used to come with (I guess, it still does – but then do you know anyone that still use Opera?). This is an updated version of the post I wrote in August 2010.
How to Use Multiple Disks Intelligently: An Introduction to RAID RAID allows you to combine multiple physical hard drives into a single logical hard drive. This allows you to mirror your data across two hard drives, ensuring you always have your important data stored in multiple places. RAID stands for “redundant array of independent disks,” although there’s a type of RAID that provides no redundancy and only increases performance. RAID Levels
4 Astounding Linux Mouse Hacks Ever since its invention, the mouse has become an extremely useful tool that makes using a computer much easier to learn when coupled with a graphical user interface. However, some of you may feel like the mouse should be capable of doing more work for you. Then there are some of you who like the keyboard better and may want to be able to use mouse functions without actually invoking a mouse. As Linux is a very flexible and customizable operating system, nothing is impossible.
Checking Your IR Remote and Replacing Your IR LED in the Roboquad: RoboCommunity Wait! Don't throw your batteries away in your remote until you do this check! If this check doesn't work, the problem may be your IR LED. If you didn't see that in your digital camera, then it just might be the IR LED, a transistor, or the CPU. Follow these simple tests, and we'll go from there. First, we are working on the Roboquad Remote. IR Codes (aibohack.com/robosap/ir_codes_quad.htm) The RoboQuad modulation scheme is the same as the RSV2 12-bit encoding described at the top of the IR Codes V2 page. The first 4 bits are "0110" for the RoboQuad (hex $6).

I can't tell you how many times I've ended up chasing my own tail trying to squeeze those last few drops of performance out of my machine. So believe me when I tell you that quality information regarding computer performance improvements is hard to find, and I don't even exclude this post from that statement! I've done my best to make sure that the information I present here is both accurate and will actually improve performance but all I can truthfully say is that this is what has worked for me and so I take no responsibility if reading this guide unleashes the song which ends all worlds, but it really shouldn't do that so if it does please let me know. 1.) RAID5 - No, not the bug spray.
Ars Technica System Guide: Bargain Box, April 2014 Since the early 2000s, the Ars System Guides have been helping DIYers to become system-building tweakmeisters. This series is a resource for building computers to match any combination of budget and purpose. The Bargain Box is the most basic box in the hierarchy of Ars System Guide rigs. It has no intent beyond a minimalist goal—creating a solid, affordable, basic computer. Think of it as the basic "office" box or "mom/dad/grandparent" box, if you will.
DIY spot welder Solid electrode holders - Solid electrode holders Solid electrode holders - Solid electrode holders Spot welder features A fine-spot welder is one of the few equipment where building yourself is cheaper than buying. There are already published a lot of DIY spot welders, this one has some unique features: It can be used in 2 welding applications: opposed and series configuration.The construction is kept very simple.Accurate electrode force adjustment.It has a solid electrode holder, made of a radiator earthing clamp.An Arduino microcontroller is used to set the weld time accurately.Creates a double pulse which improves clamping.The current can be reduced for welding sensitive parts.
