    Well it depends too on how long things take to settle out. Salt is easily suspended in water, but silt is not, so the water would be salty but not muddy. The water would also probably have lots of photosynthetic bacteria/algae in it, so you would probably have blooms of green, blue, red, and brown all over. Those blooms would uptake light and carbon through that process then as they died drop the content down the long water column. All sorts of feeding below that would create a full eecological web. If there were deep sea vents, volcanic activity breaking through the sea floor, you would have a second source of energy and chemistry at the bottom. That said, the over level of life at the surface would be limited by things like iron, phosphorus, copper, and so on. Any heavier ions would be less available at the surface because there is no surface erosion bringing them in at the top so as they are bound up in dead algae they will drop to the floor.

    The rate limiting at the sea floor will be based on energy but not too bad, you would likely see a lot of diverse life around vents and it would have a fairly large complexity over time. That said, the depth would make for less complex life due to the lack of light and associated vision. Some things would make light but it would be dangerous to make and would not be super common.

    Another interesting consideration is the geography of the sea floor. Would there be fault lines? If there are continental plates but way under the ocean they would still have movement, so subduction and so on would play out, so you would probably have chains of vents along the diverging or merging plate boundaries. Life would spread along these lines, so life would be closely related at nearby vents but distant over the surface of the planet. I would anticipate a fairly heterogeneous population over the surface of the planet in the deep, but far less so at the surface.

    It depends on the composition of the planet. If it is just a massive ball of water floating in space then it will be whatever purity that is, plus whatever space dust and impactors bring in.

    If it is basically a terrestrial planet with water on top, say earth plus a lot of water, then it would be salty. The thing with salt water is contact between the water and rock. If there is sufficient heat it will circulate, so salty water from the bottom of the ocean may be heated by magma or similar and then it will be less dense, floating upwards to the surface. Along the way it will mix and cool, leading to dispersal of the dissolved salts.

    The only way I can imagine a planet with a solid subsurface completely coated in freshwater would be if the planet snowballed hard, no radioactive materials left in the core making heat, no significant tidal pull on the core, and then after reaching a very cold temperature having slow addition of clean water from comets. That said, comets are dirty, they have lots of stuff, so you would need somehow clean comets. Still, at that point once sufficient water has hit the surface it could form a thick enough layer over the salty ocean below and start to melt, maybe from greenhouse effects. As soon as it runs away and keeps heating enough it will start to melt the core ice though, so you could have a short lived window in that freak occurrence but it will be very temporary and not at all likely.

    What I have always wanted from a phone since Android came out is what I had with my HTC Dream (the first android phone, slide out keyboard, trackball, oh god, I loved it). I had a super chunky extended battery which made it last multiple days on a single charge, or for someone such as myself made it last the full day. My current phone has a 5003mAh battery and is 8.9mm thick. I would happily take something that was 20mm thick to have all that space taken by a battery, which based on the dimensions of the battery is about 0.17Wh/mm^3. The remaining space should provide enough space for about 23500mAh which would bring the total to just under 29000mAh. At my current usage of charging twice a day from about 20% up to 100%, so around 4000mAh x2, and assuming we want to work between 20% and 80% for extended battery longevity, that would make about 17000mAh or just over 4 days of usage. That would be a delightfully chonky phone with the easy ability to keep the charge within the healthy range, not to mention the ability to have it stand on its side or upright without a stand in many cases.

    Our little monster is the same about cooked chicken, if you have it you have obviously made a mistake, that is his food and while he is a gentle god he can also be a jealous god.

    As for the fat, we have recently tried using fat from pork roasts, the fat cap is thick and soft so we can take a little of that and add it to his containers. I tried more refined fats, he will definitely eat butter, but he ends up missing the stop point and having loose stools if we use a refined fat.

    Yes indeed. We've increased fat, the meat broth is going extremely well, and symptoms are changing. My partner's enetgy levels are increasing and their overall feeling of wellbeing is indicating a positive response, so we are sticking with the beef bone broth, beef mince burgers with butter, chicken wings with butter, and some supplemental B complex alongside cod liver oil. I think we have a good starting point, hopefully the next few weeks will show further improvement.

    This is the exact type of situation for BARF or PMR. BARF (Biologically Appropriate Raw Food) and PMR (Prey Model Raw) basically focus on hitting the nutritional needs of animals like cats and dogs by matching what they would get from prey animals. This includes a fair bit of digest for dogs but less so for cats.

    My cat is doing very well on BARF and is not showing his age at all. He used to have bad hairballs, lots of itching, and very bad fur. He is now sleek and healthy with very shiny teeth and lots of energy.

    Cat tax

    His food consists of chicken cutlet (for skin, bone, and meat), chicken or lamb liver, chicken or lamb heart (for taurine), sheep brain, usually lamb kidney but sometimes beef, and then some selection of rotating meat which includes beef, pork, lamb, chicken, salmon, and prawns (sometimes called shrimp). It is about 7.5g for each of the heart, liver, kidney, and brain, then the bone is varied to change stool consistency (more bone makes harder stool) so he has an easy time there, then the meat is rotated to keep deficiencies in any specific meat at bay.

    It takes about half an hour once a fortnight to make his food and he is fed every morning. He sometimes carries his meat somewhere else to eat it so we have to clean carpet or surfaces, but honestly, he is just way too cute for us to try and do something about it.

    Anyway, maybe switching would help, the process of switching takes a while and requires building jaw strength so it is a little slow going at first, but the improvement to health is pretty great and it isn't that much effort. Oh, and his poop smells way less, and there is less of it. He has much smaller and smoother poops, nothing runny, nothing girthy, and the cat litter is able to contain the smell more effectively than previously.

    Thanks for the reply. We ended up adding the meat broth recommended by PaleoMedicina and things are improving. It seems at this point that low fat levels may be part of the issue, so increasing fat intake is the plan for the next couple of months.

    To be clear, if it he happened on and off that eliminates a bunch of potential causes. It is entirely possible this is just a loose ribbon cable or similar, though it could be a different kind of intermittent. Does it happen on an external monitor? What about a live USB? Both of those will isolate whether it is hardware or software to some degree.

    Ah, sorry, missed that. So the missed alarm notification is happening way later, like hours later, than the alarm time? That sounds like the background process is being killed in some way. In Android when you set an alarm it uses the intent system to wake itself again later. If this is failing for your alarm app only then it could be an issue with the app, but this looks like the default clock application, is that correct? It looks like you maybe installed it from the play store but it may just be an update, so just checking.

    That all said, if the clock is the only app with this problem then I would address it by replacing the app. If this is impacting other apps I can only think of a few ways that it could be caused but it should be fairly obviously problematic for other apps and solving that is beyond my understanding.

    I would recommend trying another alarm clock app from a source you trust. I would install something from IzzyOnDroid on FDroid but your milage may vary.

    Do you have a smart watch? I have a client who had no notifications coming in sometimes but not others and it turned out it was his watch taking over notifications. Disabling it was done from the watch and took effect immediately.

    Yeah, I reckon it will be much more of an impact in cheaper devices, say light bulbs and semi smart watches, than in bigger systems like laptops or servers. Given the lack of licensing fees for the CPU it makes a system meaningfully cheaper, so there is a strong incentive for various groups to work on making RISCV successful. Hopefully someone out there will do the same with WiFi chips and maybe also camera sensors.

    Not entirely certain where the issue is coming from, but for most laptops the install should finish without all of the drivers just running in the included minimal set. If you can finish the install you should be able to do drivers after that and it should all be happy.

    That said, an alternative is using a virtual machine. If you only use a few programs this may be a much more reliable and stable way to run Windows apps without messing with dual boot and drivers etc. The Virtualbox install is super easy and drivers are installed using the guest tools iso, so it is really simple to have fairly good graphics performance with limited overhead. You can also snapshot the image and have a known working state before updates, so if they gank something during the update you can just roll back and put off the update. Very handy for mission critical tools.

    Come on over to the open source free software world. Things are exciting and shiny and new while also working better every day. My most recent install of EndeavourOS took about 20 minutes with all drivers and boot stuff working correctly first try, as opposed to the multiple hour installs of 15 years ago. CalyxOS is awesome and has some really cool isolation between apps, not to mention ad blocking. And free hardware is becoming a real option with the newer RISCV stuff coming to market, allowing many more SOC designs to flourish.

    I have been in to tech for about 25 years and it has never been cooler than right now with Valve bringing immutable Arch as a base for their OS and making proton work so well that I don't even check before trying things.

    Also, man, some of the stuff coming out of the 3D printing works is just amazing. There is a guy who I follow who is working on solid state propulsion, another is working on 3D printed rocket engines, and another working on prosthetics. Cool things are still happening, just not on Windows or Mac.

    I tried a lot of things to get it under control, but most recently it was Head and Shoulders anti dandruff shampoo and another conditioner for anti dandruff, I can't remember the name of that one. I tried a bunch of strategies including daily washing, every second or third day, weekly, and so on. I also tried coal tar, Selsun, various other dandruff shampoos, and some typical shampoo options too.

    I hate washing my hair, it is anywhere between shoulder and mid back length and used to take ages to dry. At the moment I find just rinsing it out with water lets it dry very quickly, like it didn't really get properly wet. I also find it is stronger and doesn't snap off when brushing.

    Ditch shampooing and conditioning, instead transition to using a less intense washing method. I haven't used shampoo in about 3 months and my dandruff has reduced, my hair is cleaner smelling, and the dries super quickly.

    Instead of washing with soap I use brushing and water only washing. Using a boar bristle brush as well as wood brush makes brushing my hair easy and pulls the oil down over the length of my hair rather than staying at the scalp. This reduces and hopefully eliminates dandruff while also leaving the hair protected by oil. If I wash it, no soap just water, it loses a little oil and all the dirt and yuck comes out it it dries in maybe 20 mins.

    Also, it is now consistent. My hair today feels the same as my hair yesterday, so it isn't constantly something to adjust to.

    Yeah, the whole "China is doing propaganda using TikTok" line is kind of like saying Russia is using bots on YouTube. Like, yeah, maybe, sure, but focussing all your efforts on one single platform and ignoring the rest is silly. As the red team you would use as many different platforms as possible, make sure your disinformation output was broad and came from multiple, even opposing, ideological positions, and absolutely swamp the information space with junk. If nothing is reliable people don't approach things carefully, they just check out. Once people check out it is a win.

    Yep, and the while thing is moot anyway because use of the systems does not require ownership, so while the owners can exert more pressure on the algorithm and change what shows up other actors can do the same a little less easily on each platform. Propaganda is alive and well, so maybe try to limit yourself somewhat to a smaller group of people you actually know in person and be critical of information coming in.

    My partner (36 XX) is two months in to very strict carnivore, eating exclusively beef mince and grass fed butter. Total intake is 1-1.5kg been mince and 200-300g butter per day. The only beverage is water or Powerade (sugar free, acesulfame K, sucralose). Her ketones on a blood meter are consistently low, maxing out at 0.2 mmol/L today. She feels tired, fatigued, and has burning in muscles suggesting lactic acid being elevated. Just looking to see if anyone has seen something similar and if so what the solution was? Thanks
