Sudanese Freedom Rap and Guns of Brixton

1 Comment

Zoul4Revolution posted an interesting video of Sudanese protest music on YouTube:

But it was a comment on a Clash song from the same account that really caught my attention:

i’m from Sudan, we’re uprising against the fascist government of NCP, i’ve always sided with the peaceful uprising, been arrested and tortured many times, everytime I play [Guns of Brixton] I think about picking up a gun to join the armed revolution side

That led me to a quick search and the discovery of a nine video set that captures Guns of Brixton covers in numerous styles from around the world.

1) Hardcore

  • Analena
  • Dropkick Murphy’s
  • rtz global

2) Acoustic

  • calexico
  • Arcade Fire
  • Déportivo

3) Chillout

  • nouvelle vague
  • pre-school

4) Dub

  • Santogold – Guns of Brooklyn
  • radici del cemento & Fermin Muguruza

5) Polish

  • Analogs – Strzelby z Brixton
  • Alians – Bomby domowej roboty

6) Punk

  • Unwritten Law
  • The Blaggers Ita
  • Evilsons

7) Spanish

  • la furia – Armas de barrio
  • mundo livre sa

8) Rockabilly

  • Honeydippers
  • Rancho Deluxe

9) Ska

  • los fabulosos cadillacs
  • Inner Terrestrials
  • Union Jack

And of course there are many, many more cover versions…not least of all is a hit British song that borrowed only the bass line:

But after all that, I have yet to hear a Sudanese version.

Computer virus slows hospital, diverts ambulances

Leave a comment

A hospital in Geogia blamed a computer virus for system interruptions and outages over three days last week:

Gwinnett Medical Center on Friday confirmed it has instructed ambulances to take patients to other area hospitals when possible after discovering a system-wide computer virus that slowed patient registration and other operations at its campuses in Lawrenceville and Duluth. Staff members discovered the virus Wednesday afternoon and have been working since then with outside I.T. experts to fix the problem, spokeswoman Beth Okun said. In the meantime, the health system has been forced to switch back to paperwork.

Emergency and trauma patients had to be diverted away from Wednesday until Friday afternoon.

VXLAN Traffic Trombone

Leave a comment

I like the name given by one of the commenter’s on blog.scottlowe.org; it describes the traffic route in the following VXLAN example diagram

VXLAN traffic trombone

Note that even though the Windows-based workload inside the VXLAN segment now resides on a completely separate VTEP (ESXi 2, in this case), the traffic from the Linux-based workload outside the VXLAN segment continues to move through VSE 1. That’s because VSE 1 is still the Layer 3 default gateway for the IP subnet inside the VXLAN segment. Therefore—and this is where I was wrong earlier—Layer 3 connectivity is not broken, but it does have to “horseshoe” across to the other data center and then back again, as illustrated above. This is the classic traffic pattern that we see with other overlay technologies, like OTV.
