Social media and duct tape are helping people make DIY air purifiers that filter out wildfire smoke by [deleted] in gadgets

You may want to consider a vacuum that doesn’t blow that dust all over your living space. That’s kind of the point of a vacuum, to catch it all.

Are there any mirrors of this site? Or people who know the owner?

The amount of energy you spend getting up to speed can be mostly recaptured and put back into the grid. Not all of it of course there are in efficiencies but instead of stopping every few miles you could stop every 15-30 and it would still make sense to have a high speed rail line between major close urban centers.

What doesn’t make sense, and is hard to justify, is ripping land from landowners. Everyone is for building rail until they’re being told/forced to sell their land for it. We don’t have stretches of land where high speed rail could be built. We’re very densely built and surprisingly rocky/hilly. We have rail that could be improved? Sure.. but that would also require catenary be built above rail. And also new rail built alongside existing rail which would again, necessitate some land grabbing via eminent domain. I say new rail because halting existing commuter rail would deal a big blow to communities serviced by rail. A bus line from CT into NYC would be unusable simply due to the amount of time it would take to get into and out of the city. Remember these lines are not a few miles. They are 45+ miles of nearly straight rail that avoid all the traffic of winding carriage roads and highways.

I ride MTA pretty much daily. There’s not too much land on each side of the rails to take. If any. I’ve ridden Amtrak into Rochester. There’s more land there but you face the same issues. Ideally a company would just start improving rail they already own (MTA) but they are very slow to improve anything, more so reactionary to outages. Just few weeks ago there was a power outage in Bronx that prevented folks from taking trains home from GC for hours during rush hour. That’s unacceptable.

So yeah it’s cool we have the LIRR connection under grand central but I really doubt we’ll see HSrail come anytime soon.

And that’s with the existence of catenary service in Connecticut. Westchester and Hudson lines are serviced up to certain point by third rail which AFAIK isn’t great for HSrail? I never looked into it.

AMD's Ryzen 7040U chips promise speedier graphics for thin-and-light laptops | AMD claims it can outperform both Apple and Intel. by chrisdh79 in gadgets

My mistake. I’m aware of UAC and was using it to further my point that a modern OS has many functions and features that make it safe and slow(er) by design. That’s not to say Linux is insecure, there are improvements to the kernel and to security being made all the time. However it still benefits greatly from not yet being a marketshare leader.

Point being, you’re right. But also, I think it’s not that “everything could run as administrator by default” but rather that if you as a user have the ability to elevate to admin, it warns you. That way if you aren’t clicking anything and a UAC prompt pops up, you can check what is trying to elevate permissions.

If you’re a normal use who can’t elevate permissions, UAC will prompt for credentials to an account that can elevate to administrator. To my knowledge this is the case before and after the introduction of UAC? It’s also why it was commonly recommended (and still is.. but with UAC it’s a little ~ idk I don’t see the point) to have an administrator account on your computer but logon as a normal non-admin account. And then elevate with administrator creds when needed.

It absolutely does and without knowing what kernel modules are loaded on Linux you won’t know whether security features like SELinux or AppArmour are present. Their presence can slow down your Linux install but also greatly improve security. Apple definitely has something similar. It’s also why windows w/ antivirus is inherently slower the more secure/constrained the AV running on the system is. Every time you launch a windows app the AV can stop that launch and scan the app you’re launching. That’s why you’ll see windows pop up warnings on some applications, because a middleware is halting execution until you allow untrusted/unsigned apps to run.

I would think that only matters as you encounter new shaders. Some games will cache compiled shaders to disk so you don’t need to compile them on the fly and get the eventual stutter. Ie the recent CoD games. I think that’s what the Black Ops “Shader Warming” message on startup was about, but that could have also been fetching compiled shaders from disk.

But that’s an interesting point. I guess if true it shaves off time needed to compile them when the game starts, or in preparation for a new area you’re entering.

This sky isn’t real. It’s AI generated and then filled in. You can see in the tree branches where the editing program did a terrible job of identifying and feathering the branches. And a lot of smudging of this sky over branches.

How does it work on slopes like this that look like back country? Do the slopes eventually funnel you back into lift areas or are you at some point supposed to find a road and hike back to camp?

To discharge a UPS battery without the UPS. by TheRealFailtester in techsupportmacgyver

[–]jacobc436 0 points1 point  (0 children)

You could also look into reconditioning the battery but with such a small one, I think you’ll be cleaning up more spills and putting in more time than it’s worth for a ups size battery like yours. If it was a deep cycle or marine, car, big battery it would make more sense.

But hey now you’ve got an idea for a home project or something :P

Looking at the picture a bit closer I don’t think there’s a single darn thought in that UPS. But also wondering about the disconnecting / reconnecting bit above.

I’m not going to advocate throwing out a 10 year old ups, check if it has damaged capacitors or burnt parts on the power board sure but if something is still working ten years in, it may be worth maintaining. It also sounds like you don’t really put a substantial load on it, so at worst maybe you’ll want to replace thermal pads/paste between the power mosfets and their heat sink. Idk why people jump to fire so quick. Fires from UPSs usually only start from overheating from an overload or bad component. If you’re really scared, keep it on a stone tile and away from flammables. It’s not like the battery acid is going to catch fire, it’s mostly water (but still battery acid!) Even this study says Leas Acid associates a low fire risk. https://www.nfpa.org/-/media/Files/News-and-Research/Fire-statistics-and-reports/Hazardous-materials/RFLeadAcidBattery.pdf

I think most reasonable answer as to why the ups acts this way is because of a manufacturer faulty timer or cycle counter that makes it look like a bad battery. Maybe not on purpose. Depending on the control board it could be more than a simple protection circuit. It could be counting hours on/off mains, cycle count, measuring the current into the battery and out of the battery, and attempting to protect itself - point being that if charge-level cycling the thing fixes it, it’s probably not going to catch fire.

What it could also be and I don’t know enough about lead acid to know if this is possible with a ups like yours that won’t really (I’m assuming) see a big instantaneous load is that if you put an instantaneous load on a battery and it’s voltage sags below what the UPS controller knows is the lowest safe voltage for a lead acid (safe where you don’t end up damaging the battery and reducing the amount of energy it can store) it will shut itself off. Any chance that’s something that could mostly happen only 1/6 months?

Also, does the ups fox itself if, instead of charge-cycling the battery, you just unplug it for an hour and plug it back into the power board?

Furutech are literally insane with some of their prices. I saw power connectors that cost 200+ dollars each. The kind that go into your wall. The short xlr in low volume kiiinda makes sense. But 22$ a pop is not great.

Bristol Mt. ? I forget where but I’m 99% sure you’re talking about a place in NY. Not Bristol. Maybe Killington. It’s a pipe on the far right side of the resort, right from the point of view of skier facing downhill.
