TIL that copulation among noisy miners (an Australian bird) is a frenzied communal event, incubation is by the female only and up to twenty male helpers take care of the nestlings and fledglings en.m.wikipedia.org

So the title info is cribbed from the Wikipedia link which I looked into after noticing a few fledglings in a park being fed by half a dozen mature birds. Very communal creatures.

TIL the theme to Sanford and Son has lyrics. And they were sung by Ella Fitzgerald https://www.youtube.com/watch?v=xR0wIhTcQC0

I get a song stuck in my head and end up having to look up everyone who ever covered it. This one is one of the weirdest I've encountered.

TIL that climbing the full height of Everest means starting at sea level en.wikipedia.org

> Climbers typically ascend only part of Mount Everest's elevation, as the mountain's full elevation is measured from the geoid, which approximates sea level. The closest sea to Mount Everest's summit is the Bay of Bengal, almost 700 km (430 mi) away. So to approximate a climb of the entire height of Mount Everest, one would need to start from this coastline, a feat accomplished by Tim Macartney-Snape's team in 1990. Climbers usually begin their ascent from base camps above 5,000 m (16,404 ft). It’s obvious once you think about it, but at what point would you consider it in daily life?

TIL there was an attempted coup of Montenegro in 2016 to prevent it from joining NATO en.wikipedia.org

>It is believed that the plot was designed as a last-ditch attempt by the Montenegrin pro-Serbian and pro-Russian opposition to prevent Montenegro's accession to NATO,[5] a move stridently opposed by Russia's government that had issued direct threats to Montenegro concerning such eventuality.[6][7][8][9][10] This theory was re-affirmed by the court verdict handed down in 2019.[11] >On the eve of 16 October 2016, the day of the parliamentary election in Montenegro, a group of 20 Serbian and Montenegrin citizens, including the former head of Serbian Gendarmery Bratislav Dikić, were arrested;[12][13] some of them, along with other persons, including two Russian citizens, were later formally charged by the authorities of Montenegro with an attempted coup d'état. In early November 2016, Montenegro's special prosecutor for organised crime and corruption, Milivoje Katnić, alleged that "a powerful organisation" that comprised about 500 people from Russia, Serbia and Montenegro was behind the coup plot.[14] In February 2017, Montenegrin officials accused the Russian 'state structures' of being behind the attempted coup, which allegedly envisaged an attack on the country's parliament and assassination of prime minister Milo Đukanović.[15][16]

TIL: In Japan, if your spouse dies you can divorce your in-laws soranews24.com

Posthumous divorce’s technical but less popular name is a “notification of marital relationship termination” (inzoku kankei shuryo todoke) which means one is officially severing ties with the family of a deceased spouse. What’s particularly strange about it is that it doesn’t really serve any purpose for a vast majority of people aside from a government-approved official statement that someone finds their in-laws unbearable.

TIL that it's actually possible to recover data after wiping metadata on Android, but I need you help with some info

I need to ask a small favor from the good people of Lemmy World Community. In short, I accidentally wiped the `metadata` partition on my `Poco F3` and now I can't boot into the OS and access my data. I have a lot of pictures, videos and other stuff that I would hate to lose, because of a mistake. But all that is still on the phone, I just can't boot the phone to access it. Thankfully, there is a way to fix this by creating a full backup of the phone with `adb`, then using a **HEX Editor** to manually look through that gigantic file and try to find the files that were in that metadata partition. A huge thanks to [bluet33th](https://xdaforums.com/m/bluet33th.12929753/), a user from [XDA Forums](https://xdaforums.com/m/bluet33th.12929753/), without whom I would be helpless and couldn't do any of this. It might be a bit complicated and manual process, but it is possible. He explained everything in great detail here, so check it out, especially if you are facing the same problem, this will help you tremendously: https://xdaforums.com/t/how-to-recover-data-if-metadata-partition-was-deleted.4686789/ In order to find these files and put them back where they belong, I need your help, because I have to know their names, exact sizes and at least part of their content, so that I can search for it. Because I'm searching for a specific text in a text file that is 128 GB in size. I have already tried this on another Xiaomi phone, to make sure this procedure works on Xiaomi phones and it does, but that phone had `HyperOS` with `Android 14` and since every phone and android version is probably different, in order to be sure, I need this information specifically for `Poco F3` with `Android 13`. It doesn't take long, but if you don't have the time to look inside your `metadata` partition and tell me which files are inside of that partition and their sizes in bytes, you can just make a backup of the `metadata` partition and sent it to me, and I'll do the rest of the work. Here are the steps on how to create a backup: 1) Turn on your phone and boot into `TWRP`, then connect your phone to a PC, type `cmd` inside Windows search and run cmd, then position cmd into your `platform-tools` folder (if you flashed your ROM, you should already have the necessary drivers installed for the next steps to work). For example, if your `platform-tools` folder on Windows is inside `C:\platform-tools`, all you need to type into cmd is: `cd C:\platform-tools` You can also just go inside your `platform-tools` folder and type `cmd` in the address bar and the cmd will start already positioned inside that folder. 2) Then type `adb devices` and you should see your device, if you do, that means that all the drivers are successfully installed and your phone is detected. ![](https://lemdro.id/pictrs/image/c1559fc8-dba6-4818-ae63-dba402cecdf2.png) 3) Type `adb pull /dev/block/by-name/metadata` ![](https://lemdro.id/pictrs/image/e66a05f8-3278-4db4-adb5-9ba607825e29.png) 4) After that, you should see a file named `metadata` inside `C:\platform-tools`. That is the file that I'm looking for and as you can see, it takes just a few minutes to get it. You can skip the next steps (5 and 6), but I'll explain them, just in case someone wants to extract these files for themselves, so that you have them in case something like this happens to you. Of course, you can also proceed to extract the files and tell me their names and sizes. Here is what you need to do: 5) Extract the content of the `metadata` file, you can use a software like `7-Zip`. Go inside that extracted folder, then into `vold > metadata_encryption > key` 6) Inside of that `key` folder, you should see a few files. These are the important files and save them somewhere safe in case you ever need them. Since I don't have them anymore, in order to recreate them, I need to know their exact names and sizes in bytes. You can check the size of every individual file by right clicking on the file and choosing `Properties`. Then look under `Size`, **not** `Size on disk`, and in parenthesis, you should see the size in bytes. ![](https://lemdro.id/pictrs/image/a8f7f59e-3974-4792-8fd2-f976013d1229.png) Please, if you could check the size of every file and write down which file has what size. I would really appreciate it. I'm specifically looking for someone who has a `Poco F3` with `Android 13` and `MIUI`, because I'm not sure if `HyperOS` changed something, so maybe the number of files or their size is different. But feel free to post the information even if you have `HyperOS`, but please mention that, so that I am aware of it. Thanks a lot for your help, it really means a great deal.

TIL there's a known massive oil reserve in antarctica discovered only earlier this year (2024) www.newsweek.com

While territorial claims are and will likely be heated, what struck me is that the area is right near the Drake Passage, in the [Weddell Sea](https://en.wikipedia.org/wiki/Weddell_Sea) (which is fundamental to the world's ocean currents AFAIU). I don't know how oil drilling in the antarctic could affect the passage, but still, I'm not sure I would trust human oil hunger with a 10ft pole on that one. Also interestingly, the discovery was made by Russia, which is a somewhat ominous clue about where the current "multi-polar" world and climate change are heading. Antarctica, being an actual continent that thrived with life up until only about 10-30 M yrs ago, is almost certainly full of resources.

TIL that the term "marijuana" has a racist history, and meant to play off of anti-immigrant sentiments. https://www.npr.org/sections/codeswitch/2013/07/14/201981025/the-mysterious-history-of-marijuana

Throughout the 19th century, news reports and medical journal articles almost always use the plant's formal name, cannabis. Numerous accounts say that "marijuana" came into popular usage in the U.S. in the early 20th century because anti-cannabis factions wanted to underscore the drug's "Mexican-ness." It was meant to play off of anti-immigrant sentiments.

>JODIE: The reason it has been difficult for the United States to understand the Palestinian side is not only because of the media but because colonialism is in our history. We can’t face the fact that colonialism is wrong and that it steps on a lot of toes and hurts a lot of people.
