I once purchased $10k worth of bicycle car racks for my store and only when we started to assemble them did we notice they sent us the wrong products and I needed to send them ALL back. By that point the young guys who were told to clean the store had recycled all the boxes. When I saw Linus's face saying the boxes were gone I felt that.

At least they're dealing with commercial hardware. Once you get into truly top of the line hardware, especially proprietary HPC interconnects, there are also so many driver/missing feature bugs to deal with. Some things I've heard about, I'm not even sure how they managed to correctly diagnose the problem. Like on one of the supercomputers I've worked on, around 10 years ago, there was an infamous hardware-level failure that only occurred with one application and only when it was doing a full system run of over 10k nodes, using over a PB of RAM. It turns out that memory was being laid out and accessed just right to cause rowhammer faults. Even scheduling the debugging sessions in the queue for such huge full-system jobs must have been a nightmare. Plus, it's not good to have a several hundred million dollar computer consuming megawatts of power offline and not doing useful work.

The best lesson in electronics I ever had was from my father who was an electrical engineer before he retired. He told me "the weakest point and your greatest source of issues is always the connection and connectors. Check those first." Checking all the connections, even if they seem unrelated has saved me so many headaches over the years.

That visualization is really cool. When I did my CCNA class in 2006, I said someone could make a network management program that gives a visual map of your network that looked a lot like that (in my head... it was a bit sloppier when I tried drawing it). With the layer 2 traffic Cisco has flying around, you could even have it update in real time and show and log new devices connected even for a short time without asking for an IP. I was told that that wouldn't make sense because its just too much trouble to bother with an app or GUI and the CLI does everything you need better than any GUI ever could. I think some things like that came out a few years later (not that I would have known how to make it).

You obviously don't have much experience with video production. I am not sure what workflows LTT uses, but I know exactly why they need this. They use RED cameras and probably shoot in 8k 90% of the time (those cut ins aren't zooms), or maybe they don't but would like to and can't because they don't have this server up. That may not be a heavy lift if you are one dude at a workstation, but when you have a whole team of editors hitting the same server day in and day out, it can really make scrubbing, editing, NR, grading, rendering, etc. a serious pita. People don't realize just how storage intensive video production is these days. That's one reason LTT goes around helping KZbinrs install their own servers because you don't have to be computer geek to know when you are spending more time watching an hour glass spin than cranking out video. And this doesn't even include compositing which really pushes the envelope and I've seen LTT use, although sparingly.

The NASA bit looks like real time rendering, not real time simulation solve which are 2 different things. The solve process takes a week on a cluster super computer, and then you need another less "super" (but still a magnitude of order more powerful than a desktop) computer to render the results (its less rendering, more like displaying the physical results which comprise of tens of millions of cells in this kind of model). This kind of "rendering" is much more storage speed dependent and much less compute dependent.

Creates air pockets since the thermal paste has already cured before (Might be okay if you just did it that day and had to readjust the CPU in the socket or CPU heatsink to touch the IHS properly if it wasnt making proper contact, but Ive always put new paste because ive seen it cause issues in the past.
