Technically, mammals did not evolve from reptiles, being synapsids, while reptiles are Sauropsids, having split basically immediately after the evolution of amniotes.

Technology@lemmy.world•Engineer open-sources DIY radar system that's 95% cheaper than $250,000 commercial offerings, has 20 kilometer range — Moroccan engineer designs Aeris-10 radar, shares it on GitHubEnglish
2·2 days agoProbably not with SARH, multiple emitter sources would just complicate the job of the detector on the missile. Like I’m sure it could be made to work with a bit of compensation, but it would add cost and complexity to the seeker on the missile, which sort of defeats the point of such a system being cheap and easy to build. There’s also the Possibility that the returns would be too diffuse for a detector on the missile to track beyond that 20km range, so having additional sets beyond that range wouldn’t help. Probably easier and cheaper just increase the range of a single radar. Just putting the whole set on a really big missile and making it an active radar homing system might make sense with an array of sets providing warning and an initial vector, and the missile guiding it’s self in, but again, now your missile is the cost of at least one set per launch.
Not sure what limits the range on this set, but they mention a wave guide improving it, which makes me think it’s just a power limitation on the emitter or limited sensitivity on the receiver.

1·2 days agoIt depends on the system, often times they’ll have additional guidance assistance, such as an infrared seeker or some inertial posturing system. SARH just means the main guidance is provided by a seeker picking up radar from a external emitter painting the target. As supposed to ARH (active radar homing) where the missile has its own emitter and detector. Most systems aren’t just one thing these days, for the sake of redundancy and error correction.

9·3 days agoNah, that missile was visual tracking. Not radar guided. Also, way too small to intercept anything going high and fast which is generally what the patriot is for. Intercepting an aircraft requires a really powerful motor to give it enough speed and altitude to catch a plane.
This radar could maybe be used with a semi active radar guided missile, where the ground radar lights up the target and the missile just has a detector that homes in on that, which is what early patriots used. But it’s only got a 20km range which isn’t really enough for an anti aircraft system, unless all you’re worried about is something slow and low to the ground like a helicopter or cesna. Need enough time for the radar to detect, identify and lock the target, fire the missile, and have it track to the target, and something moving fast and high will be in and out of the range of the radar before all that can be done. Especially if the target is high up at 10km, which would half the effective range.
And you learned an important lesson that day.
You can run what ever you want, it doesn’t stop you outright, it just asks you a bunch of times and makes you jump through some hoops if the program isn’t from a verified source. It’s annoying for someone who knows what they’re doing, but arguably a good backstop to keep someone clueless from running something hostile. It’s a complicated enough process that someone who doesn’t know what they’re doing won’t be able to run it.
Arguably it’s overkill and them trying to force users to stay in their closed “verified” garden, but it’s not totally unjustified.
“It’ll make costs go up! It’ll cause inflation! It’ll cause a wage price spiral!”
NEWS FLASH! minimum wage hasn’t risen for over a decade and yet prices have risen faster than they did when we did raise minimum wage. Almost like, cheap minimum wages allows for more capital consolidation, and that in turn makes it easier for cartels, oligopolies and monopolies to form to enforce larger margins on low elasticity goods.

politics @lemmy.world•Trump supporters burn MAGA hats after president's AI Jesus post and pope attackEnglish
0·6 days agoI think that they were willing to go along with just about anything, so long as it seemed like he was a path to power. But, from their perspective, he’s committed the ultimate faux pa, he made gas prices go up. So his political agenda is dead in the water with no chance of recovery. This stuff is just the excuse to back away without loosing face.

0·9 days agoThe problem is that they wouldn’t see that as a failure due to not adopting a given agenda their base cares about, they’d see it as a loss due to people liking the republican agenda more, and they would then alter their agenda to be closer to the republicans.

linuxmemes@lemmy.world•With the latest changes from Microslop, this has been me in my friend group lately.English
0·12 days agoMost drivers are just in the Linux kernel so updating it will fix issues with them, unless the drivers can’t be bundled in to the kernel for license conflict reasons. In which case they need to be updated manually.
Mint has a GUI program for managing drivers that aren’t in the kernel. It actually has a GUI program for most things that would normally need commands in the terminal. Which is why I think it’s kind of insane to recommend anything else to people who aren’t familiar with using a command line interface.

0·12 days agoThe screen tearing from UI scaling being at an uneven interval has been fixed with the switch to Wayland. Screen tearing can still happen but it’s due to something being messed up in the rendering pipeline and not an issue particular to mint.

0·13 days agoPlease I beg of you, just recommend people Mint. Catchy is great, it’s very easy and smooth as arch goes.
But if you have someone who is under the illusion that Linux is hard. The moment they have any issue it might frustrate them enough to bounce off. I know so many people who have gotten recommended some flavor of the week like Manjaro, Bazite, Pop_Os or Nobara, who that has happened with. I’ve never talked to anyone who was recommended Mint with Cinnamon, used it, and then decided it was too hard and went back to windows. Plenty of people will say “well I used XYZ and didn’t have any issues” or the issues were minor enough and the answers easy enough that they stuck around, but that’s survivorship bias, the people who didn’t deal with it aren’t here to say otherwise.
So just send them to cinnamon mint, there will be no hiccups, it will just work. Maybe later they’ll be like “yah, I kind of want to see what else is out there” and then they can try other things. I get that, cinnamon mint is limited in some ways, but not in ways a first time Linux user is going to care about.

World News@lemmy.world•Macron says 'unrealistic' to open Hormuz Strait by force, urges Trump to 'be serious'English
0·15 days agoIt’s funny because it wasn’t closed by force, it was closed by nervous insurance companies, by companies not wanting to move their ships through if they’re not insured.
Like Iran isn’t patrolling it with some blockade, sinking any ship that dares run it. In fact they haven’t sunk a single ship as far as I know. They’ve just made it clear that they still pose a risk to any ship that passes And that theoretical risk is enough to spook insurance companies and stop ships.

News@lemmy.world•The Feds Say Cutting Fuel With Ethanol Will Bring Down Gas Prices. We're Not Buying ItEnglish
0·16 days agoif you crush out the oil, the biodiesel, you’re still left with a significant mass of protein and carbs, the carbs are what you would want for making ethanol.
The protein? Uh, not really useful for fuel. like maybe there is some specialized microorganism that could metabolize that to make ethanol or something? Probably it would just get tossed after the starches were fermented out of the solids. Normally it’d just get fed to animals, but the reason we’re even talking about alternative uses for soy is because the foreign animal feed market has collapsed because of an idiot old mans atavistic urges.

Lemmy Shitpost@lemmy.world•Steam lawsuits in a nutshellEnglish
0·17 days agoMicrosoft was not declared a monopolist because of their dominant market position in operating system space.
They were declared a monopolist because they used that market position to actively disincentive the use of competitor’s browsers, beyond “just including a browser”, but actively doing things to make other browsers difficult to download and use on their operating system.
Apple is not declared a monopolist because they do not own and control chrome, the really dominant market player derived from WebKit, and apple are not using some dominant market position to enforce that.
If you see things differently and think the same logic as these cases could be applied to steam, go ahead and contact epic’s legal department.

Even if you only have like 2 games your play regularly, you shouldn’t have to pay for them again. You already payed for them.

Lemmy Shitpost@lemmy.world•Steam lawsuits in a nutshellEnglish
0·17 days agoWhen you “add a game” to the steam library, you’re just creating a link to another file on your system, not really shifting the management of it over to steam (so no updates or the like), and if you logged in on another machine you wouldn’t be able to download the game through steam.
more importantly you can’t take a steam game and move over your license to use it, or ability to install/update it to some other platform. If you decided you never wanted to use steam again, that you liked some other platform better, you would still have to use steam to access any games you purchased there.
Edit: just an after thought to clarify my thinking on this. You payed to accesses that code. That series of instructions to be run on your computer. Everyone who worked to make it has been payed. If they don’t have money to keep maintaining it, they should stop doing that, or ask for further money to keep doing so. But if you want to just run the code you paid for already, it is absurd that someone restrict in what way you run a series of commands on your computer. It is indefensible, and corrosive to society.

Lemmy Shitpost@lemmy.world•Steam lawsuits in a nutshellEnglish
0·17 days agoWhat maintains Steam’s dominant market position is user lock in, not any policy they enforce or any monopoly laws they violate. The only thing that would break user lock in would be allowing migration of licenses for games between platforms, and making friend/multiplayer/mod-management systems interoperable across platforms.
Valve has made no effort to implement these kinds of systems. BUT NETHER HAS ANYONE ELSE. (Well except gog and DRM free games, but that’s only part of the issue.)
The fact that one privately owned company has such huge control of the industry is a huge risk, undeniably. But breaking up valve wouldn’t solve the problem, it would just let someone else take their place.

I assure you, the Chinese internet is not a picknick, it’s got plenty of its own wackos and weird shit going on. But the party is very quick to shut down stuff that it sees as a potential image problem, but they won’t do shit about a problem until it becomes a significant embracement.
