How Does a Password Cracker Know It’s Right? The Part Everyone Misses - ShopTalk!

Password crackers use hash files to check password guesses. The video explores this process and answers viewer questions about virtualization, hardware, and even a surprising use for an air compressor. A discussion of AI and its uses for problem solving adds to the mix.

00:00 - Start

00:39 - Hey I’m Dave…

00:54 - Do you find a crippling performance drop if your system runs all that on 1 box?

01:58 - Do the hypervisor and Docker guarantee equal treatment?

02:41 - What happens when other running VMs cause CPU cache misses?

03:34 - Didn’t this upgrade speed up your prime sieves or invalidate previous results?

04:28 - Create 3 Linux Bridges, with one being management, another storage, and the last being having users. Is this what is recommended?

06:20 - To who and what give the GPU. And mostly, how.

08:08 - I have seen docker containers that let you run windows in them. How does that work?

08:52 - Out of interest - Given your background, why not hyper-v?

09:42 - Virtualization for the ‘masses’ has been one of the most wonderful developments in the pc world.

10:25 - Could one fairly say that the efficiency of your one massive computer is accompanied by increased risk?

12:35 - Can you imagine a future where homes have a single home computer and have it pop up on your terminal screen as if you were sitting in front of the computer you just defined?

13:44 - Any issue with that compressor noise shaking those drives?

15:06 - Didn’t know you could vertically mount a 30 Drive server like that. Do you think you could do the 45 like that and it be safe?

16:38 - How does the virtualization handle the lack of OpenGL graphics hardware acceleration?

17:08 - What is your recommended config for the OS disks to install Proxmox and run TrueNAS Scale as a VM for resilience and operations considerations?

19:01 - What’s the PCI card that has multiple SSDs populated on it?

20:03 - What is your opinion on offline vs online snapshots?

21:01 - The Type 2 Hypervisor diagram should have Hardware-OS-Hypervisor-Guest OS-Apps - correct?

21:26 - I saw you had a fairly redundant UPS array setup. Could you expand on the theory, setup and performance?

22:45 - Did I see an Ecoflow and a UPS feeding the Storinator? Are they hooked up in a series?

23:35 - A greatworkshop. Who is we and us Dave?

24:41 - How are you so well-articulated?

25:48 - What is the mortgage payment for 1TB of RAM?

26:20 - Cost of Ram? Sell it and buy a Chinese EV?

26:39 - What can you do? Well, you can probably buy Greenland!

27:03 - Do you know why you only see the upper body of Dave?…

27:26 - How does it know when it has figured out the password if it’s not trying to log into a system as a particular user?

29:15 - I use (random word)(four digit number)(random word)(four digit number)(random word)(four digit number) password format. Is this reasonably secure?

30:54 - Can you use AI to reliably find a replacement part when one is out of stock?

31:30 - Can’t you just write some AI to monitor the order site to tell you when all the components are available?

31:50 - Hey Dave, maybe I can help you with the mesmerizer component problems…

32:52 - Why couldn’t a laser DLP projector be modified to produce vector graphics?

34:12 - The vector displays I worked on back in the 70s had the ability to configure the speed at which the deflection moved the beam. Does your HP do any of that?

34:48 - Can I finally do something like dedicate a PCIe device to a given VM?

35:28 - Would love to see a full episode run-through of Git and Github, targeted to the entry level programmer.

36:58 - The Friendly Coder…
