Installing CUDA 10.1 on Ubuntu 20.04 to support older GPU cards

Late last year I got a couple of ASUS 2U server’s off eBay which are now racked in my home lab. They came with some Nvidia Tesla K10 GPU compute cards in them, 4 in each, and I wanted to get them setup so that I could use CUDA & potentially rendering with either Blender or Davinci Resolve as a render farm.

As I installed Ubuntu 20.04 in them, I thought it was going to be as simple as just installing CUDA – which it was with a minor setback. The current version of CUDA is 11 which Nvidia decided to remove support for compute level 3.0 devices including the K10’s I have, so I had to install the earlier version.

Failing to configure Junos on an SRX-240H

I’ve spent a large amount of time trying to configure a Juniper SRX-240H security appliance with no luck. For some reason a simple config change just won’t work.

Right now I’ve stopped looking at it & will come back to it later, but I’m writing this just in case someone else knows what’s causing it to fail.

Getting a dial-up modem working with VoIP

Recently I’ve been doing a lot of Retro computing, mostly with the BBC Master 128 last year & this year I’m going to be doing more with other older systems ranging from a Commodore 64 that’s ready to be worked on to operating systems like CP/M & Bulletin Boards (BBS).

As I’m intending on doing some videos later on how bulletin boards were accessed in the old pre-Internet days. Now these days we have WiFi modems available which emulate a dial-up modem & then connect to a bulletin board (they do still exist) over the internet.

But that’s too clean & modern so how about using an old modem? So to do that I wanted to setup a pair of modem’s so that we can reproduce an old dial-up experience.
