Ditto. I was sick of sensationalism and click bait trash. Their research articles are also really well done and intelligent. I subscribe so I at least have one decent source without the mental burden of constantly having to sort fact from fiction.
I think a full resync then re-index will go fine. My setup is different in that I sync everything through Nextcloud and run a script that looks for changes and triggers an indexing scan in photoprism. That being said I've absolutely mutilated some photo prism databases (migrating servers, different folder names with the same content) and run full indexing and never ended up with duplicates. It's very good at stacking and cleaning up the same files in the DB so long as there aren't actual duplicates in the original storage. But again it might take 3 or more full scans to find and purge duplicates.
I am far from a photo prism expert but I can safely say the indexing algorithm is weird and takes multiple runs to finish. Logically I would expect to run it once and it would do everything in one scan but I've found it takes sometimes 3 to 5 full scans to update and properly catch up to major changes. It's almost like it acknowledges big changes and documents it but waits for multiple passes before committing it. Also it does a really good job when scanning to look or duplicate images and stacking/repointing to the valid file. I would advise running the indexing another 2 or 3 times if you are confident the 31k files are actually on storage and just not showing up on the database.
Is it possible to install a small covered entry where the peak sheds water to the sides of the front door? Just a short 4x4 roof over your front door. Regarding the valley, that could be a prime spot to quasi gutter the water; catch it and guide it down and away from the house.
I did all Samsung in my current kitchen. Microwave died in 3 years, I've repaired the dish washer 3 times now it and doesn't even clean that well and the bi metal switch that cools the stove electronics got stuck so I had to take the whole thing apart to replace a $5 part. Never buying Samsung again.
For what its worth, cheap labor markets and China especially are perfectly capable of building safe products. Most high end brands make their stuff in China. And Chinese engineers are very capable of making safe products. The issue is there isn't motivation other than a foreign country with foreign engineers probing them and pushing them to make a product the right way. Otherwise they can drop ship it cheaply with no brand, no warranty, no risk and the only exchange that matters is the sale and then they're free of all obligation. Companies with a brand need to stand behind it and are at legal risk so the stakes are completely different.
Whoa, there is a LOT to unpack here so I will do my best. Please understand as I'm an engineer by training I will always advocate towards caution rather than YOLO so I'm going to spell out a lot of doom and gloom so read at your own peril. I'm not trying to poop on your hobby/business.
Inquiries; What kind of cells, 18650s? What brand cells do you buy and do you know their use history? Do you mix model numbers? I assume these are bare cells with no protection circuitry and you add the 5A fuse? What kind of fuse, a PPTC? And is that a typo, 64 in PARALLEL? 4S64P? That is bonkers, what the heck are you doing with them that requires that kind of amperage?
OK OK, so, do you use a BMS? How are you handling these packs other than the fuse? You NEED a BMS to at least balance the 4 series strings and monitor the packs temperature and shut it down if any part of the pack gets too hot. Lithium cells have a very narrow range where charging is allowed and a slightly wider range where discharge is allowed but at some point you need to turn it off. In terms of massively paralleling the batteries this is dangerous territory unless you are acutely aware of the cells, their limits, age and tight monitoring to notice when a handful of the cells are aging (getting higher ESR and forcing the others to handle the increased current which might exceed their safety limits). The end goal is to balance the current evenly between the cells in parallel and its not trivial, if you force all the current through a handful of cells you will ignite a lithium fire.
Regarding charging to 4V and discharging to 3V, most modern 18650 cells from good vendors charge up to 4.2V with a float charge so you're leaving charge behind but 3V seems way too low. I guess it depends on how long you want the pack to last. There is max and min voltages the cell vendor will recommend but then if you ask they can give you plots of the cycle life at different depths of discharge and typically in my world we don't go much lower than 3.2V to ensure the packs last well past 500 cycles. The deeper you discharge the more stress you put on the cathode.
Finally, loose wires are certainly a cause for fires and since you're hand making these its likely your biggest risk but in addition to that dendrite growth in the cells. If you abuse the battery either with temperature, over current/current imbalance you slowly introduce dendrites which keeps increasing the chance the cell will catastrophically fail with continued cycling. Its statistics and with the number of batteries you're playing with any little bit of abuse will grossly magnify the chance of a big failure to happen. Cells can and do spontaneously fail from internal damage but its a lot more likely to happen during charging.
In summary, you are playing with some serious power levels here, I would read up some more before you get much further. Especially before you step up to 26V! I hope this helps!
You can find these in the US but they're a lot more expensive so folks always save the 50% to buy the no brand trash that breaks in a month to one year and is also a chemical bomb.
As someone who designs global battery powered products in the USA and is well versed in the regulatory hurdles, enforcing these rules is long overdue. The fact that people willingly buy and bring these illegitimate products into their home and wear them on their body is mind blowing to me. You can design a safe lithium products but doing it requires full knowledge of the chemistry, electrical design, safety certification process and some wisdom. Chinese vendors on Amazon have very little of this.
So LEDs can either be strobed or powered consistently with no blinking at all. It's a design choice and it depends on how you convert the power from AC to DC and how you want to control the brightness of the LED. It's cheaper to feed an LED power that is modulated/strobes so all the cheap vendors do that. You can also get away with strobing the LED to achieve a brightness assuming you do it at a very high frequency so our eyes don't perceive it. If you buy a quality LED light fixture there should be no strobing effect what so ever.
There is nothing wrong with LED lights. There is just a big problem with cheap, poorly designed LEDs. You can use proper optics and control the light exceptionally well and put it exactly where its needed with very little spill over or reflections up. You can also chose whatever color and color rendering index (CRI) you like but all of this costs more money and municipal bean counters are drunk on the lowest bidder. So we get glare bomb blue light shows. I used to design this stuff so feel free to ask questions.
The playlists aren't actually public they just added a third, ambiguous category with some updates they made:
"Recently Spotify has made some changes to playlist Privacy adding and extra level of privacy control. So all playlists that were previously Private are now Not added to profile, as the wording goes. This is why you see the option to Make Private on every playlist. Which means that your playlists were not made Public, they just appear to be categorized differently, so those playlists are still not visible for anyone who views your profile on any platform."
I'm pissed. I just want to pay them money and use their service and now they blindside me. I spend a lot of time and effort on my playlists and like my privacy. Why can't we have nice things anymore? I guess I will need to go back to old school mp3s and go offline again.
