After part 3, I had a fully-functioning, switched network. So then why would I want to change that? Ah, because if it ain’t broke, you aren’t doing it right. As I stated before, ACL-based firewalls are limited, defining only inbound, outbound, and local (to the router) rules on each interface. I didn’t like that limitation,… Continue reading Adventures in Networking, Part 4: Zone Defense

Adventures in Networking, Part 3: Switch It Up
When I ended part 2, I had a functioning router with a WAN interface and two subnets. But unless you only have a couple of clients to connect to the router, how are you going to turn that one interface into many? Hubs are stupid and broadcast everything. A switch is better because it limits… Continue reading Adventures in Networking, Part 3: Switch It Up
Adventures in Networking, Part 2: Initial Setup
Part 1 was the intro; now let’s assume that you just bought your EdgeRouter Lite, unboxed it, and plugged it in. Now what? It’s not exactly a plug-and-play device. Fortunately, it’s not too hard to set it up, and there is a lot of help with EdgeOS if you need it.
Adventures in Networking, Part 1: Intro
I’m no CCNA, but computer networking is fun. I’ve always been the kind of person to configure everything by hand, build computers, hack up scripts to get things done, and so on. Years ago, I flashed my Linksys router with dd-wrt in order to get the most out of it (better performance mainly), but I… Continue reading Adventures in Networking, Part 1: Intro
Building and installing BOINC on CentOS 6.5
Even with fun tools like yum, sometimes you have no choice but to build an executable from source on Linux. I found that I had to do this when installing BOINC on CentOS 6.5 due to the fact that the precompiled version of the most recent stable version of BOINC, 7.2.42, was compiled against several… Continue reading Building and installing BOINC on CentOS 6.5
Radeon BSOD update
A while ago I posted about issues with my Radeon R9 graphics card and constant BSODs when the monitor would go into power-saving mode. Well, soon after I posted that, AMD released their newest version of the Catalyst Control Center (Catalyst version 14.4, Driver Packaging Version 14.10.1006-140417a-171099C). When I updated to this version of CCC,… Continue reading Radeon BSOD update
Radeon R9 and the dreaded BSOD
Recently I purchased components to upgrade my 5-year-old computer to give it a little bit more power. I got an AMD FX-8350 8-core processor, Asus M5A99FX motherboard, and a Radeon R9 270 video card to display it all. My original plan was to use that card in concert with my old Radeon HD 4870 video… Continue reading Radeon R9 and the dreaded BSOD
Backups and USB Flash Drive partitions
I’ve reminded people before how important it is to back up your data. Personally, I use Clonezilla for whole-disk or whole-partition backups periodically, in addition to my daily data backups. It’s pretty easy to use, and it gives you a lot of options as to how to store your data. For backing up my laptop,… Continue reading Backups and USB Flash Drive partitions
Fixing your drive size
Last weekend, my computer froze up out of the blue, and then refused to boot. Since I got the dreaded “Unmountable boot volume” error, I figured it was the hard drive. My C: drive was a 250GB beast from when I built my first computer in 2005, so it was clearly getting a bit old.… Continue reading Fixing your drive size
Review: Samsung Galaxy Nexus
Last weekend Julia and I ended the tyranny of our T-Mobile contract (even though the merger with AT&T fell through, I was sufficiently spooked by the spectre of giving money to AT&T that we bailed). AT&T being out of the question, as well as Sprint, our choice was none else but Verizon. Verizon had two… Continue reading Review: Samsung Galaxy Nexus
