Interesting Failure Modes – SD Card Arching

I’ve been using Raspberry Pi computers for several years. A few months ago the Raspberry Pi B I had hooked up to my TV and running OpenElec, stopped working. The Pi was locked up and then wouldn’t reboot when I pulled the power cord.

It’s an original B model, with just two USB ports, so I didn’t think much of it. I prepped and put in place a replacement Pi, also running OpenElec, and threw the Pi into a drawer for further inspection..later. I got 4 years faithful service from a $35 computer so I wasn’t complaining.

Some weeks later, I had an idea that I wanted to use a Raspberry Pi for so I grabbed the questionable unit and got to work.… Click here to read more!

How To: A Clean install of Windows 7 in 2016

Maybe I’m alone here, but I still have occasion to install Windows 7 from time to time. For a while, that was no big deal; Install the OS, update, update, update and you’re good to go. Lately though, the process has become far more cumbersome. Not only does the process take ages to complete, but when you’re done its always nagging you to update to Windows 10. What follows is my process for getting this done without too much hassle.

Firstly, I’ve not created anything new here. I’ve simply found a series of tools and bit of information online that helped me along the way so I’m compiling it here for my future benefit.… Click here to read more!

Install Centos 6 on a Non-PAE Machine

I have a Thecus N5200 that was modified to have a VGA port. Though the machine will run a variety of current Linux distributions, I wanted it to run Centos 6. Unfortunately, the N5200 doesn’t support PAE, which Centos 6 requires.

The first major problem is that a Non-PAE machine won’t even boot the Centos installer CD/DVD. You have to find some way around that. There are several ways to get around that but they are all quite complex and time-consuming. Plus, as time goes on they work less and less. The old software needed is harder and harder to find.… Click here to read more!

Thecus N5200 as a Server

Back in 2007, I bought a Thecus N5200 to use as bulk storage on my network. I’ve spent many years using and fighting with the unit but it wasn’t until my storage needs out grew the 5 SATA disks it could hold that I considering sending it off to be recycled.

It’s a pretty basic unit. From Thecus it arrived with 5 hot swap SATA disk trays and a simple web-based management interface. The interface wasn’t great at telling you exactly what the state of your disks were so I lost my data with this unit more than once. Over time though Thecus added a method to install add ons and little by little people started to write add ons for the unit and actually increased its feature set.… Click here to read more!

Portable Pi – Raspberry Pi with a Motorola Lapdock 100

Having read countless accounts online from people who have taken various lapdocks and paired them with a Raspberry Pi, I thought I would give it a try myself.

I went to Ebay and purchased a Motorola Lapdock 100. It’s a small unit with a cable that comes out that back. This cable has a header with a Micro-USB and Micro-HDMI connector on it. General wisdom seems to be buying series of adapters and cables and then sort of whittling them down until they fit. I dutifully bought the necessary bits but when the Lapdock arrived it seemed much easier to just take apart that cable header instead.… Click here to read more!

Installing X-Plane 10 on Fedora 20

I’m a bit of an aviation buff and have been known to spend a fair few hours playing flight sims. My favorite sim these days is X-Plane, and thankfully it runs on Windows, Mac and Linux. My current host for X-Plane is Fedora 20 and since there is a bit of extra effort to make it run properly, I thought I’d outline my process here.

First and foremost – This post assumes you have installed the appropriate graphics drivers and are not running whatever drivers were just included ‘in the box’, as it were. My system has an NVidia GeForce GT 640 and I use the akmod-nvidia drvivers from RPM Fusion, which works great.… Click here to read more!

pfSense and the ALIX.2D2

In a recent post I detailed my current saga of server trouble. This time around I was having router trouble causing this website, and others, to fall offline. Not that much fun…

When life hands you lemons though, one needs to try to make lemonade. Since I needed to replace hardware I wanted to make sure I put in place some hardware I could trust to last another 5 years and hardware that would sip power… not guzzle it down like the now dead antique desktop tower computer had. My needs are pretty low performance-wise and I don’t need to have a super high performance setup.… Click here to read more!

Servers, You Gotta Love them…

My home network is more complicated then most. I host some web sites, my email servers, and various other ancillary services that the average person doesn’t need, or want to worry about. As an IT person though it behooves me to have a test bed to try out new things, without the risk of losing company data.

In recent years I have been using IPCop as the gateway between my home network and the outside world. Generally speaking, it’s worked just great. I rarely had to reboot it and the web interface was usable, if slow. The only draw back for me is that they don’t seem to favor low power machines.… Click here to read more!

Norco DS-1220, Linux, and Green Hard Drives…

I’ve had my Norco DS-1220 for six or seven months now and have some time to adjust to it and really feel out it’s performance. When I first setup the system (transitioning from the Thecus), I had a 2TB RAID 5 array built with 5 500GB Western Digital Caviars. When the array was at around 95% capacity I decided to add more storage and began looking for the most cost effective way to do that. I always use generic 3.5″ drives and I usually pay as close to $100 each for them as possible. Typically when the time comes for me to add storage it makes sense to double my capacity and Murhpy’s law always seems to work out that drives twice as large as the one I am replacing are at about $100 each.… Click here to read more!

Apple Leopard Server: Two Weeks Later

So, it’s been installed and running for two weeks. I think I made it pretty clear in the first review that it’s good but not perfect, nothing is and over the past 14 days I’ve had a chance to really dig in and learn new things and fix some problems.

If you have been following my twitter updates you may have noticed some, shall we say, frustrations, with the VPN server that come with Leopard server. Me, being lazy, setup a simple PPTP VPN for my use that I use to connect back home when I’m on the road or looking to secure my traffic from whatever random wireless I’m connected to.… Click here to read more!
