Raspberry Pi 3 released, faster CPU, integrated Wifi

It's only been a year since the Raspberry Pi 2 Model B was released, and to mark the 4th birthday of the Raspberry Pi a new Pi is being released today. The NEW Raspberry Pi 3 Model B! This new Pi offers a faster CPU at 1.2Ghz, along with integrated 802.11n Wireless LAN and Bluetooth 4.1 with Bluetooth LE. Over the last few months I'd been wondering if a new Pi might come this year. After all, hardware keeps advancing so there's not much reason to stand still on RPi2 for long. I also didn't want ...

First 10 Minutes with Raspberry Pi and Windows 10 for IoT

My very first Raspberry Pi arrived yesterday. I'm super excited to get playing, and frankly I probably should have gotten one of the older versions sooner. Now that I've got Pi, I can start hacking! Since this is a Raspberry Pi 2 (same goes for the Raspberry Pi 3!), it can run the new Windows 10 for IoT making it easy to build apps for it with C# and Visual Studio. Well, I haven't gotten to actually building any apps yet, but was able to get Windows 10 for IoT setup. Install Windows 10 for IoT I... [More]

Cheap PC 2009 - Custom Built PC under $500 that includes Windows Vista Home Premium

Two years ago I posted "Cheap PC - Build a Vista Premium Ready system for under $500 including the OS". I can't believe that was two years ago already! Anyway, the original premise of the post was to point out that you could build a "cheap" PC for under $500 that included and could run Windows Vista with "Aero" Glass Enabled. After I wrote that post I decided that I would try to remember to write a post like that every year to serve two purposes: 1) chronicle wh... [More]

Vista Experience Update: Disk Defragmenter Revisited

About 5 months ago, way back when Vista RTM'd, I posted about how Vista now automatically defragments your hard drives. This is a really neat feature, especially since I would never remember to defrag until my system started to get noticably slow. So, I thought I would revisit this to just see how well is it working. But, How well does the automatically scheduled defrag work? I was wonder this, so I decided to check the defrag stats available from within the Disk Defragmenter tool. And to my d... [More]

Can you run Mac OS X within Virtual PC 2007 on Windows?

Does anyone know if Mac OS X can be run within Virtual PC 2007 under Windows? I've searched and can't find any evidence of this being possible. I am thinking about possibly doing this because I would like to do some software testing on Mac OS X, and I would rather spend less for just the OS than buy a Mac Mini. Mac OS X - $129.00Mac Mini - $599.00 If anyone has any clues please let me know. Update 5/22/2007:The day I originally posted this, I also contacted Ben Armstrong, through his blog (V... [More]

Windows Vista Device Drivers for Belkin F5D7000 Wireless Network Card

Update 2009-08-08: Belkin has since released a new device driver for this network card that supports Windows Vista x32 and x64. You'll want to try their driver first before continueing on to my "work around" solution below. I did try this new Belkin driver with Windows 7 and it didn't work, so now I'm back to my work around... You can find the driver here: Belkin: Support: F5D7000 Driver Support Page Or, alternatively you can download the driver from the following direct link: Belkin F5D7000... [More]

Cheap PC - Build a Vista Premium Ready system for under $500 including the OS

People keep talking about how Vista (w/ Aero enabled) will only run on high-end systems, and that everyone will have to buy a new computer in order to run Vista. Well, I have a laptop thats 3 years old (2.4Ghz Celeron, 512MB Ram) and it runs Vista ok without Aero glass enabled (because it doesn't have a capable video card). Based on that, pretty much any system that is 2 years old should run Vista (w/ Aero enabled) just fine as long as it has 1GB Ram and a video card that support DirectX 9. ... [More]

Virtual PC 2007 released with improved performance!

Microsoft released Virtual PC 2007 today. I've been waiting for this since Virtual PC 2004 wont install on the 64-bit version of Vista. I just installed Virtual PC 2007, turned on hardware virtualization and loaded up the Ubuntu virtual machine I previously installed on Virtual Server 2005. I'm actually seeing that the exact same Ubuntu virtual machine performs much better under Virtual PC 2007 running on the same PC as it did under Virtual Server 2005. I did see one peculiar th...

There seems to be alot of posibilities with this. The iPhone also runs Mac OS X. Here are some links to images of the iPhone: I wonder what kind of development tools/options they will have available for the... [More]

Hitachi's New Perpendicular Recording Technology involves some bits that dance to the music

In March 2005, Hitachi demonstrated their perpendicular recording technology. This method of storing data on hard drives allows for an awesome amount of data in a small space. Hitachi demonstrated a storage density of 230 gigabits per square inch. Hitachi expects to see products ship at 230 gigabits per square inch in 2007. With this they'll be able to store 20 Gigabytes instead of 6 Gigabytes on the one-inch Microdrives, and up to one terabyte on the 3.5inch hard drives.Yeah I know I'm thinking... [More]
