Simply yet more proof of Twitter being a terrible platform.

Billionaires like Larry Connor pursuing these expeditions with experimental submersibles seem to be driven more by ego, novelty-seeking, and a reckless desire to conquer challenges that provide little scientific value, rather than any practical purpose that hasnā€™t already been accomplished. Their decisions to risk their lives in this manner over something so well-explored is stupid and unnecessary.

The blade would have to be partway in your neck, because the subs implode that fast.

Yes. Because it comes in two parts. The OS level package and the browser extension, if the extension canā€™t communicate with the OS level package then it wonā€™t work.

Valve did promise us that they were going to improve VR support on Linux quite a while back, good to see that theyā€™re keeping that promise.

They promised so a while back, some time just after first introducing the Steam Deck. Theyā€™re keeping that promise.

Asahi Lina on Steam (Creator of Asahi Linux) (steamcommunity.com)

Hereā€™s Asahi Linaā€™s Steam account. I thought Iā€™d share it with you guys as Lina is testing games and fixing bugs, and if youā€™d like to support her by gifting games, this is her account so you can do so. Proof From Her Last Live Stream

Yes, literally the end of her last Livestream.

Np. I forgot to add the stream link, thatā€™s my bad. Kinda stayed up all night for Linaā€™s live stream.

I will warn you that her Live streams are really technical low level coding, though in her next stream sheā€™ll be testing games and stuff so itā€™ll be a little bit more entertaining than usual.
If youā€™re interested in that kinda stuff, itā€™s a gold mine for learning and she does answer questions from the chat. Also, some pretty notable developers will show up to the live streams from time to time and hangout in chat.
I enjoy it. ā˜ŗļø

Using btrfs compression as a backing device for Zram

So, Iā€™m sure some of you know. If configured, you can use a backing device for Zram for scenarios where Zram canā€™t compress the data, e.g. when itā€™s full. For this you can use pretty much any supported partition format, including btrfs, what I realized is that you can used btrfs disk compression on top of that. Question...

TL;DR :Zram itself doesnā€™t compress data in the backing device. The data written to the backing device is stored unmodified by Zram. Zramā€™s function is to compress data within its allocated RAM space. Once that space is full, any incoming data, compressed or uncompressed, overflows to the backing device unmodified by Zram.

If the data is overflowing from Zram into the backing device because the Zram block is full, that doesnā€™t necessarily mean that data is uncompressible. It simply means that thereā€™s no place to put it even if it was compressible. The truly incompressible data ideally should be stored in the RAM thatā€™s not allocated to the Zram block device, unless that RAM space is also already taken, then that data would go to the backing device. The scenario Iā€™m thinking of is a lot more specific. Ofc, Zram would prioritize truly incompressable & idle data first when pushing into the backing device, keyword there is ā€œidleā€, which supports the idea that the data isnā€™t necessarily uncompressible.

Already compressed media, for example, canā€™t really be compressed. In fact, if you try, you might just find it actually ends up bigger than the original.

Thereā€™s no case where this would happen, the data being pushed to the backing device is always unmodified by Zram, regardless if itā€™s compressible or not. Also, already compressed media would not necessarily be seen as incompressible by Zram. Zram can still compress already compressed data to some extent, depending on the type of compression used and the compressibility of the original data. For example, if the original data was compressed using a simple algorithm like LZMA, Zram might be able to achieve better compression using a more advanced algorithm like LZ4.
However, the benefit of compressing already compressed data with Zram is usually minimal as youā€™ve already said.
This is the primary purpose of https://www.kernel.org/doc/html/next/admin-guide/blockdev/zram.html#recompression to handle cases where the primary algorithm is unable to efficiently compress certain data.
Also, Btrfs uses a built-in pre-compression heuristics algorithm to analyze each file and determine if compression is beneficial. Comparatively, Zram has no such mechanism so it attempts compression regardless.

Tbh, deep down the rabbit hole is an understatement. hereā€™s a more detailed documentation of Zram.

Yes. Because people like you lean ridiculously hard into one way or the other. We need a variety of food sources to sustainability receive all the nutrients we need to live. Eating a majority let alone an only meat or plant based diet is the complete wrong direction, and this is scientific fact. At least with plants itā€™s possible to find substitutes, however some substituteā€™s arenā€™t nearly as sustainable as the vegan agenda tries to lead you to believe, Cough cough almonds cough cough. May, Spirulina save us all.

Canines are literally omnivores

Oh my God!! šŸ˜± Itā€™s almost like humans are omnivores too šŸ˜±, who couldā€™ve guessed?

Rustmilian, (edited )
@Rustmilian@lemmy.world avatar

those of herbivores are hands or hooves

And then it just completely goes downhill from hereā€¦ Show me a single fucking herbivore that has hands. šŸ‘Ž

Also you realize itā€™s possible that creatures can evolve into omnivores from prolong environmental pressure, right? Are you not familiar with evolution? Did you sleep through life science?

Also, you realize that from that same exact source there are thousands of papers and studies contradicting that paper. You might as well become a farmer with how well you pick cherries.

@Rustmilian@lemmy.world avatar

Itā€™s almost like thereā€™s different evolutionary factors of how canines are formed. oh my God what the fuck wow, who could have guessed. šŸ˜± I wonder what the human evolutionary factors were. It couldnā€™t possibly be a lack of food and a evolutionary benefit of eating a much wider diet or anything.

Gorillas are omnivores.
Pandas are ex-carnivores whoā€™ve transitioned to a specialized herbivore diet over millions of years of evolution do to environmental factors. Additionally, you realize bamboo has a shit ton of protein and carbohydrate in a ratio similar to a hypercarnivores diet, right? Thatā€™s how they were able to transition in the first place, Pandas digestive system and gut microbiome still resemble carnivores, theyā€™re not typical herbivores. In fact pandas have been known to occasionally snack on meat and consume small animals or carrion, aligning them as super picky omnivores.
And PANDAS DO NOT HAVE HANDS, not a single fucking species of bear has hands. They have specialized paws with pseudo-thumbs which is actually a modified wrist bone to grip and eat bamboo, not true hands.
Similar to Pandaā€™s, Koalas have specialized paws with curved claws adapted for gripping and climbing trees, not hands.

At least you got 1 thing right, Gorillaā€™s have hands.

Go tell Pandas to stop occasionally & opportunistically snacking on small animals. You seem to love pushing your veganism, so why donā€™t you go do that to the pandas?
Not a single thing I said was contradictory.
Iā€™m thoroughly convinced you slept through life science. Itā€™s a waste of time talking to you.
Just as you shown me; the take away Iā€™ve learned is that Vegans argue the same way that fucking flat earthers argue and thatā€™s honestly sad.
