If you look on loopnet, the cost of office versus warehouse per sq ft is staggering. It's a large visual indicator of a bubble.

I've been looking for 1500-3000 sq ft for a light manufacturing space for around two years. In my area warehouse $/sqft is $5-7 a year. Office space is $13 for old and dated layouts. I have no use for that dotcom era conference room. I need 10 ft dock doors, tall ceilings, and reliable 3 phase power.

Buying land outside my metro area and building new is becoming the only option for me until this crash actually happens. Sprawling out of the metro would only bite me down the line because the labor market is even tighter in rural areas.


What would be a non bubble price to you for industrial space?


In 2022 I would have accepted $10 per sq ft if it ticked all the boxes. There's been a few spaces I kicked myself over not signing soon enough ($6 per sq ft, 3200 sq ft, large with ample power 480v with 600 amp service, concrete roof, dock door)


I've not been successful trying this with HPE servers. Most server fans (Foxconn/Delta) run 2.8 amp or higher. Not aware of any "silent" gaming grade fans that use more than 0.38 amps. That's not even considering the CFM.


Why would current be relevant here? Shouldn’t operating voltage be the only thing that matters?


Amps * Volts is power. Power is a proxy (a moderately good one) for air movement (a mix of volume/mass at a specific [back-]pressure).

It’s not likely that a silent 2W fan will move a similar amount of air as the stock 14W fans. The enterprise gear from HPE is pretty well engineered; I’m skeptical that they over-designed the fans by a 7x factor.

Operating voltage tells you “this fan won’t burn up when you plug it in”. It doesn’t tell you “will keep the components cool”.


This makes sense. Most of the Jetson/Xavier/Nano boards already use a Carmel ARMv8 chip. I just hope this spurs more development in ARMv8. Currently the majority of ARM is ARMv7 (smartphones and Raspi).


I think it's more about having CPU IP more than what CPU IP they have used in Jetson/Xavier to this point (though it is a helping factor). HPC also loves ARM these days and nvidia makes huge cash on that already.

Smartphones have largely been ARMv8 for the last 5 years. Raspberry Pi is as well these days.


Raspberry Pi 4 uses ARMv8 according to Wikipedia: the ARM Cortex-A72.

Pi 3 and the V1.2 revision of the Pi 2 were ARMv8 too (Cortex-A53).

edit: also re smartphones, Android SoCs started to move to v8 CPU cores 5 years ago, in the Nexus 5X/Pixel 1 generation.


Currently anything Li-ion is around $1.50 per pound (Midwest US prices) to be accepted for hazardous waste recycling. This means it costs you the consumer to have your laptop battery recycled.

I work with a company that recycles older hybrid batteries from Toyota, Honda, Ford. Most of these are NiMH and pay $0.40-$0.80 per pound for the Nickel value alone.

So a NiMH hybrid battery is worth $50 for the core from a Prius, but a lithium battery from a Nissan Leaf would cost you ~$700 to recycle.


I think the repeaters would block out any of the mobile radios. So you could see the dispatchers easily, but the individual mobile operators (EMS, Fire, Police) would be hard to distinguish.

If the mesh was every Digital TV tuner inside a municipality, then maybe the mesh could triangulate position.


Are you following the open inverter forums?

No, but it's good to see another RX-8 build thread. (I've come across a few already, but everyone seems to approach their conversion a little differently.)

I've been setting up old GPUs for folding@home and recently acquired a Nvidia Jetson AGX Xavier for machine vision.

Currently I'm building a 6 camera rig using Raspberry Pi IMX219 or IMX477 cameras to create an ultra high FPS rolling shutter.


This is an awesome development for building out machine vision or microscope cameras. It'll be great to adapt the Pi to an Amscope or Dinocam for inspecting small part features in an industrial setting.

If you're just dipping into Permaculture, get a few books by Ruth Stout. Her method of "no-work" gardening is a pillar in the homesteading, self-sufficiency, and permaculture communities.

Warning, her writing style is closer to rambling than academic/professional.

Applicant does not present live performances of a prurient sexual nature or derive directly or indirectly more than de minimis gross revenue through the sale of products or services, or the presentation of any depictions or displays, of a prurient sexual nature.

That's a strange way to exclude sex workers.
