I mean it would be very space efficient to build such a space on some of where the parking lot is. A smallish parking space is 8'x16' so take 3 spaces, assuming each pod needs an exterior space of 4x8, stacked 2 high you can easily fit at least 32 pods in just 3 parking spaces with enough space leftover for hallway and a communal kitchen or something. They already have a public bathroom and shower facility so they'd only need the sleeping space and some communal recreation space that they can keep open 24/7 for their students staying in the pods

Banning advertisements to kids is the correct approach. I've observed with my own kids, they genuinely don't yet have the mental faculties to be critical of advertisements. They see something advertised, they want it, simple as that. Their brains aren't developed enough for content with advertising nor product placement.

Maybe there's a sweet spot in limiting it to toy ads and ads for other content on the same platform that they're watching. I'm not sure, I'm not a child psychologist, but kids should not be presented ads for energy drinks/drink supplements (I wish I was kidding but I've specifically had to have a conversation with my daughter about why we're not buying the drink band owned by a certain YouTube celebrity who got himself banned from returning to Japan) nor for restaurants (especially not fast food!) nor for sketchy paid mod launchers for games (fuck you to the like only YouTuber who focuses entirely on Wobbly Life and is constantly advertising that!), nor most of the other things I've seen advertised to the kids recently

The way I see it, if my kids start finding ways to circumvent parental controls we should be able to have some frank discussions about what the parental controls would be setup for

I setup my wife's old Android phone to be super locked down via parental controls. Only approved apps, no installing apps, time limited etc. set it up so my kids can use it on days when we need them to zombify for a bit in the afternoons

Its kinda mind blowing how YouTube Kids is their go to and they don't move to any other apps until they've run out of time on it (family had already let the cat out of the bag about the existence of YouTube so I had to limit rather than block) and we still have had to block a number of concerning channels they kept watching. Its crazy how they'll just zombify staring at YouTube but then for the age appropriate games they're so much more engaged and actually seem to have a healthier interaction. Its also sad how some of the content I see the kids watching on YouTube Kids has writing and direction about on par with Disney's current crop of age appropriate shoes for 3-6 year olds (and from what I've seen Nickelodeon isn't much better right now). My kids primarily watch PBS Kids and a handful of shows we carefully selected on DVD because we want to minimize the brain rot (as well as minimize annoyance for us)

Would a safety deposit box at a bank be an appropriate option for your off-site backups?

For an rail network that runs 24/7 they're going to have crews specifically to wake up should there be a problem on the busiest sections of mainline as this hoax indicated there were. That's a significant amount of dollars burned if they close the line due to a citizen reporting heavy damage to the bridge, and just waiting until 8am on the next business day to actually look at anything.

I strongly suspect what happened was they woke up their on-call inspectors (or scrambled an inspector who worked nights, which a rail network may very well have) informed them of photos circulating showing significant structural damage to this 150 year old viaduct, so they roll up and see the exact same viaduct in the exact same shape it's been in for their entire life and call up their boss and say "oy you wakin me up for this shiv? The bridge is bloody fine! Check your sauces mate!" (And after reporting that it was a hoax probably went and did a more thorough inspection to make sure their bases were covered)

Let's be real, if the media called import taxes "import taxes" and not "teriffs" Trump's import tax campaign would've much more rapidly collapsed

Hey it's never too late to get things better under control! My parents only just started that journey and they're old enough to be grandparents

Honestly the questions you're posing require a level of market analysis that could fill an entire white paper and be sold for way more money than I want to think about. Its a level of market analysis I don't want to dive into. My gut instinct from having worked in the tech industry, working with datacenters and datacenter hardware at large companies is that the AI industry will contract significantly when the bubble pops. I'm sure I could find real data to support this prediction but the level of analysis that would require and the hours of work are simply more than it's worth for an internet comment.

You have factors including what hardware is being deployed to meet AI bubble demand, how the networking might be setup differently for AI compared to general GPU compute, who is deploying what hardware, what the baseline demand for GPU compute is if you simulate no present AI bubble, etc. etc. it's super neat data analysis but I ain't got the time nor appetite for that right now

That's super interesting! I didn't know other languages handled side thoughts better!

Oh yeah machine learning as a technology will survive, and eventually it will be implemented where it can do what it's really good at, but right now it's being shoved into everything to do things it isn't good at, so you end up with a super expensive to run, energy inefficient tool that runs worse than with traditional algorithms that can be run client side or on a single much cheaper server (I'm oversimplifying the server architecture for brevity)

Think customer service chatbots on ever car dealership's website. Traditionally these were extremely simplistic and usually just had canned responses based on keywords in the customer's written message and would quickly cascade the customer to a real customer service rep as soon as things got out of scope. Now with LLMs companies are running those as the customer service chatbots and the LLM can do anything from agreeing to sell a new car for a dollar to providing scam or invalid contact info to referring the customer to a competitor. There's no knowing what the AI will do because it's non-deterministic and you don't want that in customer service!

Right now we're in the bubble phase where every single company is finding some way to shoehorn AI into its business model so they can brag about it. Fucking Logitech added a remappable AI button that brings up a ChatGPT interface and just spends Logitech's money on tokens with ChatGPT. That's pure bubble behavior. Once the bubble pops we won't have literally every single time you open a car dealership page spending an LLM token or 5, you won't have Amazon running AI chatbots on every product page just for asking about that product, you won't have every website just giving away free unrestricted access to LLMs. That's what I'm talking about.

AI demand will drop when the bubble pops, and while it will be higher than it was 8 years ago, everyone is going to be very skeptical of anything AI, just like folks are still skeptical of mortgage backed securities over 15 years later, or just like people are skeptical of commerical websites without a clear method of financing 25 years after the dotcom bubble. People remember these things and will take a while to warm up to the idea again

Is there enough demand for thousands of servers with purpose built ARM processors (which may or may not have any publicly available kernel support) driving 4-8 600w a pop Nvidia datacenter chips though? Yes some will be repurposed but there simply won't be the demand to fill immediately. Realistically what will happen is companies operating these datacenters will liquidate the racks, probably liquidate some of the datacenters entirely and thousands of servers will hit the secondhand market for next to nothing. While some datacenter structure city empty and unmaintained until they're either bought up to be repurposed, bought up to be refurbished and brought back into datacenter use of torn down, just like an empty Super Walmart location

Some of the datacenters will be reworked for general compute, maybe a couple will maintain some AI capacity, but given the sheer quantity of compute being stood up for the AI bubble and the sheer scale of the bubble, basically every major tech company is likely to shrink significantly when the bubble pops, since we're talking companies that currently have market caps measured in trillions, and literally a make up full quarter of the entire value of the New York Stock Exchange, it's going to be a bloodbath.

Remember how small the AI field was 6 years ago? It was purely the domain of academic research, fighting for scraps outside of a handful of companies big enough to invest in am AI engineer or two on the off chance they could make something useful for them. We're probably looking at a correction back down to nearly that scale. People who have drank the coolaid will wake up one day and realize how shit the output of generative AI is compared to the average professional's human work

 

A recent storm damaged the siding of my house so I'll have to have it replaced. The thought occurred to me to run some network cabling behind the new siding (and likely new insulation) while its all pulled off. Should I run standard riser cabling or outdoor-rated cabling if I do so?

Obviously the most ideal solution is standard in-wall but I don't have the appetite for such a project given half the house was built in the 19th century and I know such an undertaking would involve quite a few surprises that I almost definitely lack the know-how to handle, and I'll probably be moving in a couple of years so I don't want to invest too much time or money into the endeavor.

Alternatively is there a good type of conduit I could run instead?

 

I placed a low bid on an auction for 25 Elitedesk 800 G1s on a government auction and unexpectedly won (ultimately paying less than $20 per computer)

In the long run I plan on selling 15 or so of them to friends and family for cheap, and I'll probably have 4 with Proxmox, 3 for a lab cluster and 1 for the always-on home server and keep a few for spares and random desktops around the house where I could use one.

But while I have all 25 of them what crazy clustering software/configurations should I run? Any fun benchmarks I should know about that I could run for the lolz?

Edit to add:

Specs based on the auction listing and looking computer models:

  • 4th gen i5s (probably i5-4560s or similar)
  • 8GB of DDR3 RAM
  • 256GB SSDs
  • Windows 10 Pro (no mention of licenses, so that remains to be seen)
  • Looks like 3 PCIe Slots (2 1x and 2 16x physically, presumably half-height)

Possible projects I plan on doing:

  • Proxmox cluster
  • Baremetal Kubernetes cluster
  • Harvester HCI cluster (which has the benefit of also being a Rancher cluster)
  • Automated Windows Image creation, deployment and testing
  • Pentesting lab
  • Multi-site enterprise network setup and maintenance
  • Linpack benchmark then compare to previous TOP500 lists
