It's human nature to explore. Whether the frontiers are way out there in space or deep down in Maryannis Trench, some people are visionaries and some are not. There are plenty of them that are not high profile like a few of well known ones.

As a child I wanted to be in the Mission Control command center with all that equipment, not in the spacecraft. ;) We used to hear Rocketdyne testing rocket engines back in the 1960s. Even from miles away it was a distinctive roar.

Well obviously the company will not be selling that trip again. Every time I go on vacation, I sign at least one waiver. It doesn't mean that it cannot be challenged because information was withheld or misrepresented. One doesn't have to be a billionaire to take a $250K vacation. :LOL: That...

I did not see anything new there. At this point it is pretty obvious that the submersible was a flimsy POS. Maybe I just assumed that there were safety regulations for any vessel that is used for commercial purposes.

I'm not sure how that will work in certain industries where the equipment/instruments are run with Windows, yet are on a totally separate network that cannot connect to the internet directly. Just updating the OS and software is a PITA process. The costs of change controls are high (I see many...

But we should still have a few years when personal systems can have a regular OS? I don't need internet very much. If the OS doesn't work without it, then I'd have to freeze it in place before then. MAC users are going ape over the file sizes and hardware performance needed for the Abode AI...

For who, the basic office workers? For any significant workstation usage wouldn't the latency kill productivity?

Young people do foolish things and now it stays around potentially forever. In earlier times what happened in the 1980s stayed in the 1980s for example.

My test results of the two 12V-9Ah FR are not so great. I'm not seeing much more capacity than the 8Ah and not a lot less impedance either. I'll put them in an olden APC 1300VA UPS for an AV center but it's not worth the one-third extra cost over 8Ah IMO. In my 24V 1500VA UPS with six (2...

It's possible that the float is enough because the battery is always on charge and not set aside. If the last 15-20% takes several hours or one hour may not make a practical difference.

I wonder what JTR thinks about most UPS charging batteries from bulk to float without an absorption stage like a typical charger? How many hours are needed at 13.5-13.6V to reach 100%?

Sure that is a good analogy, but it shouldn't be that difficult in the 2020s. I can plug a 20TB HDD into practically any mainboard.

All the AGM batteries are designed to float around 13.5-13.8V at room temperature. The 6 small UPS I've recently tested are all between 13.52-13.67V per battery. A large one is 27.1V and the other one cycles around 26.9-27.2V. There may be some hysteresis with the panel meter, but a graph...

They will die soon enough and you don't want it to happen at a bad time when your NAS and computer experience an uncontrolled shutoff like mine. :(

It's a a question of how old they are. I have a special battery thingamajig, but you can put a constant load on them and test capacity manually. Your UPS is a 1500VA model?

I sent you a conversation. I prefer local since you can check the battery voltages in the store. Lead batteries that go too low are permanently damaged and if you get an old battery online it is a PITA or impossible to return. Local stores also take the old batteries for recycling.

The M.2 capacity sucks and the fact that 4 PCIe lanes are needed per M.SSD limits quantity use to devices with lots of lanes. Otherwise switching or bifrucation is used and then performance is weak. It's a huge problem in the MAC land too.

So I tested the internal 12V 14Ah battery and capacity results were great. The OEM was 12Ah IIRC, but after 17 hours of charging the 2021 battery it is at 13.17V. That seems like forever to charge. :( I have a couple more smaller batteries to test assuming another UPS charges them enough. At...

You are building an electric bus for the Danes? Is there enough sunlight in the winters?

Capacity in any 5-year period will increase substantially. Unfortunately we may be stuck with the stupid M.2 for a long while in client systems.

It looks that they are fairly large Chinese company that makes battery solutions for EV and large industrial or commercial installations, not much for consumers or at least not directly.

SSDs should be good for five years or are you assuming that hard drives last longer based on historical data? I assumed that the Heliums are better than ambient atmospheric drives, but there still can be mechanical problems from being idled for years.

How much does the network interface slow down the output compared to the CPU? Will the IOpops performance be worse than a single NVMe?

I thought about those, but decided it is too small and too slow. Maybe if there were multiple ports and link aggravation. For now I'm upgrading some of the internal SSDs from 24.5 to 41GB. Maybe in 2025 I will build with 64 internally and then NAS will be a different flow.

I watched that show a few times in the early 70s, but it made little sense. It wasn't funny and it wasn't scary. The characters seemed like a bunch of dimwits. I found this. https://knowyourmeme.com/memes/lets-see-who-this-really-is

No, they are cheap stuff. I discovered there is no good way to use it as a UPS So where does one buy a good UPS battery that is safe and legal? From what I read the A123 are Chinese, maybe good Chinese. ;)

I think I remember that virus a few years ago. I try to keep mainly offline with an important computer. I suppose you have a relatively small number of image files, under 50 TB?

The 2019 batteries are external in a 21°C room. Maybe that is part of it?

Now I'm getting 89.2% at C/4 for some batteries that I'm almost sure are from 2019. For some reason they are doing better than the 2021 batteries at C/6. :unsure:

One of the issues for the LiFePO4 batteries that match the size of the 12V 8A and similar 2.56" width batteries is that are low current. You need 40A not including losses.

I bought some weird LiFePO4 battery thing a few years ago. It was like this when new. IIRC the max curent was rather low, so it was not very useful for a full power UPS. I was planning to use it directly for the 12V telecom devices. I'm not sure where it is now, probably stone dead from disuse.

I'm pretty sure that I've never seen the capacity at near 100% at C/4 or C/6. VRLA batteries are typically rated at C/20 and of course they are never quite 100% even then. I think that one above is about 90% of new, so still good for the relatively low load purpose.

This is from a 2.4 YO 12Ah battery, tested at 2A today.

Like a foreign hacker virus?

How do you test the UPS batteries? My battery thingamajig is suggesting C/20 and somebody suggested as much as 4C (576W for 12Ah), which is way beyond the power I can handle. Besides, isn't that wearing out the battery just by testing it?

I have no idea how you jumped to that. The original question was "My sister is trying to maintain control over her kids' internet time."

I thought the 4080 was already downgraded to the 4070Ti that I received in Q1. :( I'm not sure how your intelligence interrogates the detainees/suspects but video card is a strange graphic.

I only have about 147,485 RAW files currently in the computer with those and many more on the NAds. According to the Wiztrees, there are 89.5% CR3, 4.0% CR2, 2.7% TIF, 0.9% or less of others. Those are just WIP though and will vary massively as they are deleted and replaced with others. I...

It seems obtuse, but I'm not up to par on video cards humor. What exactly are those video cards doing for the detainee?

The Nvidias H100 Hopper is as costly as a small Honda. 🤪 I wonder if there is much profit on them.

At some point doesn't nVidia want to move to one technology and the 30 series is getting old and lacking the DLSS? I read on the webs that they are not expected to implement a 50 series until 2025. If $300 is too high and sales volume are poor, then there will be sale prices. I'd really like...

So what; they are going to kick him out? He's not living there forever.

It's not rocket science. When the children act up they need to have their toys taken away for a while. Unless the kid is a sociopath any parent should be able to identify when their children are lying.

The RAW files must be on another drive. All I noticed was video games???

Sure, but many of the legal issues will be over any misinformation presented to the participants.

The more one reads about it, the worse that whole concept was. I can hardly believe that anyone would go into that deathtrap if they had enough of the information.

I recently discovered that there was a second X670E Beta BIOS update later in May that cut the boot time dramatically (about in half). It now boots faster than ever, though still a little slower than the X570. It's now far more palatable to power down frequently, which is welcome in the summer. :)

Carbon fibres work great in tripods and monopods if the parts are glued properly. It's not too unusual for the legs of the cheap Chinese tripods to fall out from where they are attached to the metal sockets on the spider.

I am using the old-school dynamical disk function with the 4TB NVMe SSDs.

Everything is on again after removing all power and batteries for a while, but it's not clear why a YAMAHA was not communicating with the box on Lithium. I guess everything is supposed to be in a certain order or something. Maybe I should just remove that UPS from service for now.
