Dave’s Garage: Shop Talk

Cracking UNIX DES Passwords with a Dual GPU Dell 7875 Workstation: ShopTalk!


Listen Later

Dave turns a Dell 7875 workstation with dual RTX6000 GPUs loose on an old Unix password file to see how quickly he can break an old UNIX password file from a PDP-11/70. Just to be clear for YT, no actual password-cracking technology is demonstrated or revealed within the episode, only the results, and DES is an old 1970s UNIX technology of historical interest only, no longer used.


00:00 - Intro

00:32 - Crack a password on the beast ?

03:09 - Calculate Pi to a billion places. Run it on all your comps taking time hacks?

03:37 - What about generating those fractal images that used to be all the rage.

04:13 - I want a super duper high pixel count array Mandelbrot generation without using damned biblts and do single pixel at a time calculations.

05:31 - Would creating a processing client for Folding@Home be a good task for your dual GPU system?

05:43 - Would running a distributed computing project and drag racing other computers be a good test/demo for it?

07:13 - How about a procedurally generated video/game which uses your input to generate the environment live?

07:36 - Set up as many MAME instances each running a separate game as able, and then set loose some type of AI to play each one simultaneously

08:00 - Setup two local coder models and I’d rig them up in a continuous loop with each other attempting to build an AI to play Tempest.

09:15 - Why not try to plot the general trend of humanity from 1 to 5 years?

09:27 - Can your fancy dell find a profitable market for AI?

10:17 - What would a top machine do a Diffusion image, compared to my lowly RTX3060?

10:47 - Most power buttons are a simple pushbutton Why not just use a wifi spst relay wired parallel with power button?

11:34 - Glen’s Basement channel when?

12:37 - Are Glenn and Dave as AI as the intro?

13:45 - Isn’t Joseph describing a USB Device Server?

14:40 - Dave have you written any C# with Visual Studio 2022 or newer?

15:44 - I bought a JetKVM and have not had much luck with the video and it does not support a fixed IP

16:29 - Dave, you mentioned the N-Word (Netware). I was curious what your exposure and opinions are on it?

17:43 - I would be curious about you talking ( in depth really) about your opinions on building a windows machine in 2026.

19:49 - Tailscale masterclass please Dave?

21:48 - Do you ever actually have to use the giant backup generator you have? How much of its capacity would you use with all your retro computers running?

23:12 - What process do you use to generate the audio for the clip at the beginning?

24:00 - In Excel you are typing a formula, and you want to backspace one character… why the frack does Excel assume you want to reference a cell address at that particular moment instead of letting you finish editing the formula by hand?

24:54 - Are all techies the same? We just love anything that’s mechanized, electronic or both?

26:15 - Hopefully Glenn looked in his mom’s basement for those boards you are missing ?

27:28 - You guys are great, and apparently Glen’s presence increases female viewership?

28:01 - For some weird reason, my wife likes to hear Dave talk?

28:22 - Glen, are you in the basement making content again? You are not online with the Dave guy again?

29:23 - I was all set for a Corner Gas themed Dave’s Attic…complete with table hockey?
