Anime Music Video NIN The Becoming Lain, Akira & Ghost In The Shell
This is awesome: Anime Music Video NIN The Becoming Lain, Akira & Ghost In The Shell.
It’s a mashup of old school anime classics with Nine Inch Nails soundtrack.
fonts-noto-color-emoji
Today I discovered the fonts-noto-color-emoji Ubuntu package, which I installed to get support for emoji fonts in Konversation, my IRC client.
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?
Four pillars of virtualization

- CPU
- memory
- storage
- network
Circle that presses them
There’s a great quote from Carlos Castaneda in Journey to Ixtlan: “A warrior proceeds strategically. If one wants to stop our fellow men one must always be outside the circle that presses them. That way one can always direct the pressure.”
Good learners
I was reading about Neil Postman and found myself on the inquiry education page. It says that all good learners have:
- Self-confidence in their learning ability
- Pleasure in problem solving
- A keen sense of relevance
- Reliance on their own judgment over other people’s or society’s
- No fear of being wrong
- No haste in answering
- Flexibility in point of view
- Respect for facts, and the ability to distinguish between fact and opinion
- No need for final answers to all questions, and comfort in not knowing an answer to difficult questions rather than settling for a simplistic answer
EarthBound
I read somewhere recently about EarthBound which is apparently a classic computer game. But I don’t recall ever having played it and I wasn’t able to find it on Steam.
Update: oh, I heard about it in The AI Revolution is Rotten to the Core
