Chrome web sandbox on XenClient

There’s lots of software out there that sets up a “sandbox” to protect your system from untrusted code. The examples that come to mind are Chrome and Adobe for the flash sandbox. The strength of these sandboxes are an interesting point of discussion. Strength is always related to the mechanism and if you’re running on [...]

Linux bridge forward EAPOL 8021x frames

XenClient is no different from other Xen configurations in that the networking hardware is shared between guests through a bridge hosted in dom0 (or a network driver domain in the case of XenClient XT). For most use cases the standard Linux bridge will route your traffic as expected. We ran into an interesting problem however [...]

OE-Core Yocto gcc timeout

I’ve been thrashing around trying to get the upstream OE to build an image for me. Today I finally made a concerted effort over a few hours to dive deep and do this right. It turns out I was using the “old” OE repos when I should have been using the “new” build system from [...]

LaTeX for your Resume / CV

I’m far from a ninja when it comes to but I’m a big fan. I’ve written a bit about formatting logical expressions for past homework exercises. I’ve also used it in blog posts for doing the same. It’s a very useful tool even if you’re just a using basic templates like me. A major driver [...]

sVirt in XenClient

It’s been 5 months since my last post about my on-going project required by my masters program at SU. With the hope of eventually getting my degree, this is my last post on the subject. In my previous post on this topic I described a quick prototype I coded up to test an example program [...]

Troubles with Ovi Store after upgrading N8 to Anna

I took some time yesterday to upgrade my beloved Nokia N8 to the new(ish) Symbian^3 Anna build and it wasn’t a smooth upgrade. Upgrading through the Ovi Suite went well enough but applications like the Ovi Store just wouldn’t work after the upgrade. The Ovi Store application would install and start but would sit on [...]

ALIX3D2 Arrives

I’ve been hoping to upgrade my older ALIX2D3 router / firewall / wireless access point for a while now. While taking a few hours off from work over the holiday I surfed over to PCEngines and bought myself a Christmas present: a matching pair of ALIX3D2 boards and a Compex WLM200N5-23 MiniPCI card (802.11an) plus [...]

Atom Based Home NFS

It’s been a while since I’ve posted any new content but that’s not because I haven’t been doing anything worthy of mention. During the few breaks I’ve had from my day job I took the time to replace my QNAP 419p NAS with a custom system to host NFS shares. Here’s just a quick laundry [...]

You do not have sufficient permissions to access this page

I’ve been working on a set of scripts to backup the wordpress instances on my server. While structuring these scripts I realized that I hadn’t structured my WP installs consistently. I had played around with using table prefixes and hosting multiple WP instances in a single database but eventually I just broke them out into [...]
