Luna is abrasive, essentially like shards of non safety glass. The dust on mars is soft, it's been blowing around since before the dinosaurs died off. The main issue with martian dust is electrostatic charge, but that's easier to manage than lunar dust.
Semaglutide has been used for diabetics for roughly 20 years. The FUD angle is just people rambling against something that doesn't affect them personally. Everyone knows the only things that matter are what effects "you", everything else is just fantasy. If we could rid ourselves of that mindset we could build a much better world.
There's anecdotal accounts of GLP meds helping with a range of addictions. Of course in science anecdotal accounts are the lowest tier of evidence, that's only top shelf in law.
More importantly we have decades of irrefutable evidence that diet and exercise alone are about as effective as abstinence only sex education. It's great there are people that can just decide to eat less, but it's foolish to assume that can work for everyone.
It's odd how people act as tho there's a "moral argument" against using a tool to help reach the goal. It feels a lot like the argument that "morals are from religion", as if you need god to know that murder isn't really a productive activity (unless you work in a slaughterhouse).
I wish American money could go back to having "mind your business" printed on it instead of "in god we trust", it was a huge loss to all of us when that garbage was passed. It was also a huge loss when everyone just decided to go along with saying "taxpayer money" instead of saying "public funds/money", but slippery psychological slopes are everywhere.
Terzepitide took me from always wanting food to actually being able to focus on other things fully. I was concerned with being able to inject myself weekly, but it's easy and worth the 1-2 minutes a week. If you start, the dosage schedule is more a suggestion than an absolute. I noticed side effects getting worse so I dropped back to a lower dose and have held there for a couple months now. Only real drawback has been from a friend giving me a hard time after seeing the vial in my fridge, but he seems to be coming around after seeing obvious results.
One could even argue food is a lifetime chemical dependance. An assortment of chemicals really with the amino acids, lipids and sugars involved. People who are against these medications typically draw arbitrary lines for what treatments are "acceptable".
Until starting tirzepitide I always thought about food, now I don't. Had depressive issues since I was a teenager as well. I took Wellbutrin for 20 years and had an interruption in the last six weeks due to an insurance issue. Payed for the tirzepetide out of pocket, take that once a week, my depression is manageable without the Wellbutrin for the first time in my life. I'm still going thru depression, but that's due to my husbands death in early March. If I wasn't taking my weekly shot I would easily be morbidly obese and probably suicidal. The cost isn't an issue either, I would spend more on food that I'm not buying or eating each month than it costs to buy the medication.
Just because something might not be interesting to someone doesn't mean it has no value. I have no interest in sports, but that doesn't mean they shouldn't exist. I could argue they shouldn't be as prominent in society but that's a different argument.
If you have struggled with your weight, depression, have early warning signs of cardiac problems and a range of other conditions it can be worth considering semaglutide or terzepitide. As long as you stick to the lowest dose that's effective the side effects are minimal to non existent. Categorically dismissing these drugs is as silly as refusing pain meds because "god designed us to experience pain".
Vantablack is carbon nanotubes grown on a surface. Black 3.0 or 4.0 and Mosou black are paints that perform significantly better than regular black but are still measurably less than Vantablack. Visually the difference is small, but durability is far better.
essentially none of the videos have sound on the iOS client. It's rare I ever come across a video with sound. Very frustrating to use.
Not directly, bu whatever they are eating ultimately gets energy from the sun. It's really just about how pedantic you are on redirection of energy.
That's where a larger group helps versus the 3 men on Apollo, or 4 people for Artemis. Having a larger pool of personal will ease a lot of social friction. It's also likely that a laser comms connection will be readily available, that is a large part of why starlink developed laser link between satellites.
I expect before people go that SpaceX will put a small constellation of starlink satellites in orbit of mars. I could also see them putting a bunch of probes on a starship and having them separate in martian orbit, landing at candidate sites. The combination of the 2 will lead to a lot of valuable data to decide where humans will land first.
Around mars it's likely the satellites will be in a higher orbit, but there's no internet needing low latency there either, at least not at first. They could be a basis for a mars positioning system. If a lower orbit is used they could potentially use synthetic aperture radar to get high resolution scans of the surface. It's probable that many starships will already be waiting on the surface by the time humans make the trek out there. Presumably loaded with food, equipment parts etc... For how quickly the ships are fabricated we aren't looking at a scenario where ships are in short supply.
The reduced air pressure on mars also means keeping warm will be significantly easier than in Antarctica. Convective heat transfer is much slower. Protecting against conduction isn't too challenging. Seeing how a spacesuit is necessary on mars building one that can retain enough heat to be comfortable isn't really a herculean effort. Far easier than a suit for the moon, mars doesn't really have grains of regolith that are consistently sharp and abrasive like earths moon has. On mars there's more a fine powdery substance, it was called "fines" in the red mars novel.
It's irritating to see people claim it's colder than antarctica but never a discussion how the reduced atmospheric pressure makes it easier to keep warm.
Mars not having a magnetosphere isn't as short term a need. The atmosphere stripping away is on geologic timescales, not human ones. Even then, we could put a superconducting ring between Sol and Mars and get the same effect as far as solar wind stripping the atmosphere. It would be a big project, but not impossible. It's also a project that won't possibly start until people live there permanently.
Worrying about the atmosphere stripping away is akin to worrying about the smaller of Mars two moons being on a path that will impact in 100,000+ years with the surface of mars.
In many problem domains mars is an easier target for long term habitation than the moon, the biggest challenge is getting there. The retorts from people here about farming miss that we don't need 'soil' to farm, there are techniques that mostly just need water and vitamins that can dissolve into it. At Epcot they have a system to breed fish and use the fish waste for feeding plants to grow. Throw in mycelium for handling human waste and you have an efficient system for augmenting food production.
A serious effort for mars will have as many or more spinoff technologies as Apollo gave us. The computers we are using today are further along in development from the massive influx of effort to make computers that could fit in space capsules. With the acidification we are causing in the ocean, a reliable way of converting C02 to oxygen at scale might be needed here on earth to prevent an oxygen collapse within decades. Climate change is a bitch, and it could give an excuse to start charging people for breathable air here on earth so the cynics may be right about that eventually happening. That possible disaster just isn't on even most climate scientist radars yet.
There will be other spinoff technologies we just don't see yet. The large rocketry needed to get there also opens up resource extraction from near earth objects. There's massive material wealth just barely outside our present grasp. It would be nice for materials like platinum and gold to follow in the footsteps of aluminum in becoming common enough to be usable for trivial items. Aluminum was a precious metal just a few hundred years ago in its refined form. Gold nanoparticles look like a candidate that could make current GLP-1 drugs obsolete, it works in animal studies but not tested in humans yet. Manufacturing in space is also on the verge of practicality. Metal foams, ultra low attenuation glass and optically transparent aerogels can be made in microgravity that are superior to the versions that can be made here on earth. Metal foams would be ideal for making ships, cars and planes that are much lower weight than we can make now without loss of strength, less weight means fewer watts per mile and less material needed.
The people whining about the idea always seem to miss the secondary effects of making the effort and always see to paint the optimistic take as naive, really they are just demonstrating short sighted thinking.
I have an automation that turns it on whenever I take the phone off the charger. You can also set it up with locations. So I have an automation that tweaks a few settings when I get to one of the disney parks here in FL. It's usually keep the screen fairly dim on manual brightness, but set it to auto there. Its really hard to see the screen when it's bright in the great big room.
I have an M2 Max with 64Gb of ram. It handles everything I throw at it. Runs the 30ish gigabyte deepseek model fine. I will admit for gaming I pretty much just stick to Cyberpunk 2077, Minecraft, Stray, Viscera Cleanup Simulator and old games with open source engine options. I'm happy I can play Cyberpunk with my screen on full brightness using 30w, compared to my Xeon windows machine taking 250w for lower frame rates.
The Hobbit films were shot in native 3D, and 48hz. It's a shame we can't get the high frame rate version at home, more of a shame we can't get Avatar The Way of Water at 48. The hobbit could've worked as 2 films, but 3 was stretching it too far.
If you take stereo photos and want a way to view them. Go to an Antique store and get a stereoscope. They can be purchased inexpensively. Have your photos printed on 5x7 with the images arranged like a stereo card. Perfect color, prints are inexpensive, if your willing to send away you can get photos on matte paper so they look better than most stereo cards.
The lenses you can get for an SLR tho are much better than what rPi cameras usually come with. If you use film era fully manual lenses you can get amazing quality for next to nothing. If your shooting objects that are still, taking longer exposures or exposure brackets is trivial. I wish there was an GUI program for tethered cameras that still had an option to capture multiple frames each time you trigger it and average them for an output frame. It's strange that feature was removed, in the SD video era there were lots of options for that.
The catch is that if you charge less than a small difference to your next closest competitor people will think something is wrong with it. Saw it happen many times working at an antique store for years. It was amazing how often raising prices made things sell that had been sitting there for months, or longer. You rarely want to make something too inexpensive, along with never using the word "cheap". There's also issues with trying to give something away for free. Generally people value something more depending on what they paid for it. Upscale brands like Coach and Channel exploit that aspect of consumer psychology.
That makes sense unless you are in an area with hurricanes. In places with a high probability of a hurricane hit they have started doing framing with the zip sheathing so it looks like a monopoly house, then they add overhangs that can break off in severe wind rather than taking the roof with it.
It's a shame more houses don't get built with ICF, including the roof. Living in an area that gets hurricanes at least every other year I would happily take a smaller house to get something that could stand up to category 4-5 hurricane.
I'm a FL resident (firmly NOT republican), Goto Disney Parks once or twice a month. It's amazing how people there will walk just inside a doorway and stop, or be in the center of a walkway with a group of half a dozen while oblivious to the mass of people around them. It's common to see people stand as a group blocking the entrance to attraction queues or even just entering the park they don't have their pass out before they get to the podium or they scan their pass wait a few seconds and then put their right index finger on the reader, both slow things down alot. Oddly those people are the ones you come across later in the day that insist on standing so close behind you in queues that shifting your weight will make you bump into them, it seems strange people don't grasp there's nothing to be gained from being close enough to smell what the person in front of you had for breakfast.
It's more common than you would think to come across a wild turkey(those bastards deserve the annual culling), deer, geese, coyote, a few months ago there was a black bear in tom sawyers island(they closed off a third of the park until it was captured). A few weeks ago I was leaving the magic kingdom and was going to walk from the main parking lot monorail station over to the bridge toward the Polynesian resort to the parking lot(I loathe the trams, prefer walking). I was just rounding the walkway and came across a snake that was upset about something in the center of the walkway. I think it was just a black snake, but I have a phobia for that particular type of animal. I reversed and took a different route. I have actually seen snakes a few times over the last couple years around the Polynesian resort, turkeys encounters are very common at the campground.
People think that because the parks are very safe as far as public places go that everything in the Disney bubble is "safe". If you're in an area where you aren't familiar with the local wildlife you should always err on the cautious side. But generally people are oblivious to anything around them.
Have you looked at DietPi as a low resource OS? It's my default choice for a SBC like the Pi. They have versions for x86 too.
The people making content generally have no idea about video compression. Or they only understand it at a cursory level. It's a safe bet that set designers and decorators have no idea about video compression. Early productions seemed to understand that aspect but that was mostly in the days of 56K modems and ISDN lines. It was a small enough niche that only technical minded people were doing it.
I found the easiest way was vacuum sealing some chocolate and sticking it in a souvee at 92f overnight. Agitate a bit after it's melted and a while before removing it from the warm water. I use the method for making tempered cocoa butter to use as seed in my tempering machine. The exact temperature varies by type of chocolate. The trick is getting it just below the point that type 5 crystals form. It's perfect to make seed chocolate for when I use the tempering machine, saves a lot of time and there's the convenience of having a big pool of chocolate for molding, it's better to have a bigger pool than you need so that when you pour out molds you can do it directly into the working pool.
I had an original iPhone the day it was released. Lots of people viewed it as too expensive and "why would I need that".
When iPad came out plenty of people had the notion that "no one really needs that, it's just a toy".
This is a pattern with apple products going back to the original Macintosh.
I lost my mom to cancer when I was 17. She fought with it for 6.5 years prior. Even knowing it was coming it was devastating. 24 years later I still miss her, I'm sure I always will. It hurts knowing that I'm now older than she was when she passed.
When it happened it was the worst emotional pain I had experienced, it does get better in time. Your feelings are valid. You don't have to feel whatever anyone else thinks you should feel. It feels cliche that it gets better in time, in my experience tho it does. I'm sorry your dad and family is going thru that. Oddly I found Cyberpunk 2077 to be therapeutic on coming to terms with that situation. In the game you play a character who essentially has a terminal disease, there are a lot of moments in the game that rang very true to the emotions I experienced.
When your dad eventually departs, you are allowed to feel anything. I have been the type to laugh at a funeral remembering something funny the departed said or did. If you feel like crying that's ok too.
It lost because there were only 3 prisms made. It also required a lot more lot as running thru an optical splitter means at least half of your light was lost, it's not a big issue today. Modern cameras are insanely more sensitive than film was at the time. Alfred Hitchcock used this on "The Birds". In the YouTube video they got a great result even with a smaller studio than would have been used on Mary Poppins. The trick needed the screen as far back as you could get it to minimize the chance of spill, that used to be normal on blue screen before the software improved.
