• Matthew Weber ☛ Home Lab Evolution

  Something I’ve planned for a while now, but had been putting off, is a significant refactoring of my home lab. My setup consisted of a huge HP workstation with a Xeon processor and 128GB of ECC RAM. It was entirely overkill for what I used it for, and it was costing some serious money to keep running around the clock.

• Hackaday ☛ Linux Fu: The USB WiFi Dongle Exercise

  If you’ve used Linux for a long time, you know that we are spoiled these days. Getting a new piece of hardware back in the day was often a horrible affair, requiring custom kernels and lots of work. Today, it should be easier. The default drivers on most distros cover a lot of ground, kernel modules make adding drivers easier, and dkms can automate the building of modules for specific kernels, even if it isn’t perfect.

  So ordering a cheap WiFi dongle to improve your old laptop’s network connection should be easy, right? Obviously, the answer is no or this would be a very short post.
