Also variously known as “stripboard” and “veroboard” I got myself some of this TZT 10PCS DIY 2.5×6.4 2.5*6.4CM Prototype Paper PCB Universal Experiment Matrix Circuit Board Single Row Continuous Hole 25x64mm. AU$4.71 for 10 pieces, delivered. The boards are fairly small, 25x64mm.

And also some of this: diymore 5PCS/Lot 50X100mm 2-3-5 Joint Universal PCB Boards Single Side Copper Prototype Print Circuit Boards Breadboard. AU$4.28 for 5 pieces, delivered. These are a little larger at 50x100mm.

I still haven’t found exactly what I’m looking for when it comes to stripboard, gonna keep my eye peeled. This is what I have so far:

FILCO Majestouch 2SS Edition Keyboards

I ordered two new keyboards this morning. I got a 104-key one and an 87-key one. The gory details are documented on the keyboard page on my wiki.

Usually I like to buy V3 keyboards from WASD Keyboards in America. But the price for the two keyboards delivered would have been AU$841, which was just a bit too expensive for me.

So I had a bit of a hunt around and I found these Japanese FILCO Majestouch 2SS Edition keyboards on Amazon:

They both come with MX Speed Silver switches which are the ones I like.

While I was researching I found the following content mill articles which I enjoyed reading to learn more about mechanical keyboards:

In my feed today a note from Adrian Black from Adrian’s Digital Basement that he was retiring from his infosec job and going full-time content creator for his YouTube channels. His announcement is here. It’s fun because I managed to be the first person to wish him luck and my name was in the credits because I now support him on Patreon! You can see the proof in the screenshot below! :)

QEMU/KVM Attaching a Virtual NIC Directly to a Physical Interface

Man, it took me a while to figure out how to do this! Over on Attaching a Virtual NIC Directly to a Physical Interface I figured out I could use this XML in Virtual Machine Manager (virt-manager) for my NIC device:

<interface type='direct'>
  <source dev='enp9s0' mode='bridge'/>
</interface>

That then gets expanded automatically to something like this:

<interface type="direct">
  <mac address="52:54:00:ce:5b:09"/>
  <source dev="enp9s0" mode="bridge"/>
  <target dev="macvtap4"/>
  <model type="rtl8139"/>
  <alias name="net0"/>
  <address type="pci" domain="0x0000" bus="0x10" slot="0x01" function="0x0"/>
</interface>

Update: ah, balls. This doesn’t completely work, because the guest can’t connect to the host, and vice versa, even though both the host and the guest can connect to the internet. This is a problem for another day. Maybe this or this will help?
