Studies have been done comparing gasoline vs. ammonia and while there are differences overall the dangers and mitigations are about the same.

The future of shipping is ammonia. It has, pretty much, all the attributes of fossil fuels but being NH4 it doesn't produce an earth warming byproduct.

I recently had the experience of wiping windows of an Asus laptop I bought and the process was trickier than usual. It turns out that the 'USB Image Writer' that comes with linux and that you use to create a USB drive with the linux of your choice is no longer up to the task. The bios of the laptop would not allow the USB to boot up unless I created the USB with an entirely different software, in my case I used the balenaEtcher software (I believe other software will work too) to create the USB and only then would the USB boot up and allow me to wipe and reconfigure the partitions on the 'hard drive' (which in this case was an SSD).
It took me an extra couple of hours to get this to finally work. At this point I'm not sure if it's only the new Asus bios that are doing this unfriendly thing or if it's an industry trend.
A real pain in the ass in any case.

Re:LG Smart TVs have security bugs that could let hackers hijack them

I have a LG Smart TV that I use as a dumb TV that's driven by a Asus pn51 "palm of our hand" computer running Linux Mint. Finally a Logitech MX Ergo 'thumb ball bluetooth mouse' allows me to sit on the sofa across the living room and happily browse the internet, watch movies, youtube and almost anything else you can think off. (All the details here are just in case someone else would like to do something similar, this could be a starting point.)

My recollection is that gparted wouldn't allow me to adjust any partitions until I loosened up the available space in the system partition. I guess gparted checks all the partitions to make sure everything is as it should be before it allows changes.

I ran into a similar situation not long ago on the system partition of a linux installation. The partition was too small to begin with and as new updates piled up there was almost no space left to start deleting stuff. It took me about half an hour to find a subdirectory with a tiny bit of stuff that could be deleted. It was like being in a room so plugged up with junk that you couldn't open the (inward swinging) door to let yourself out.
From the tiny beginning I started being able to delete bigger and bigger spaces until finally it was clear and then of course I resized the partition so that wouldn't happen again. The End.

Re:Radios, how do they work?
on Tuesday March 26, 2024 @11:14PM (#39835342)
Yes it does but it's the lambda symbol that's the impostor. An analogy of how it really works is to think of the transmitter as a water hose that is spraying water into a bucket, which is the receiver.

Re:Radios, how do they work?
on Tuesday March 26, 2024 @09:49AM (#39827797)
It's because energy created by the transmitter must degrade as one over R squared in the far field. The frequency (or wavelength, have your pick) has nothing to do with the energy transmitted because energy must be conserved. Putting in the frequency term then violates conservation of energy between the antennas. Then, at the receiving antenna the error of conservation of energy is then patched up by assigning a bogus 'gain' at the receiver. The transmitter and receiver are asymmetric but the path loss equation pretends that they are because that's easier for most people to understand and it works out 'end to end'.
Re:Radios, how do they work?
on Tuesday March 26, 2024 @09:18AM (#39827445)
For sure they do not work the way the "Path Loss Equation" would have you believe they do. The path loss equation violates conservation of energy ie the frequency or wavelength term depending on how it's structured cannot be in the equation. And the receiving antenna does not have any 'gain' other than physically getting bigger or smaller, though the transmitting antenna can have gain depending on shape and size. That is, the transmitting antenna and the receiving antenna work very differently. Yes, end to end the path loss equation gives the right answer but in between it's scientifically illiterate.
Re:The lifetime tooth decay vaccine is now available (in Honduras)
on Monday March 25, 2024 @11:01PM (#39823895)
Maybe for you but for me it didn't work at all until I used the 45 degree angle (with electric tooth brush and tooth paste) approach. For me I could tell that things were getting better when I could stop flossing for a week and then floss and there was no bleeding or tenderness. Before the 45 degree technique my gums were tender from flossing almost all the time. I'm not sure that every mouth is different but I'm pretty sure that there is a lot variety. My mouth creates a lot saliva that, in turn, creates a lot plaque.
Re:When Did Dogs Become Our Best Friends?

It's tricky for women to raise children in the wild. Especially once kids get to the ages between 2.5 and 8 when they'll want to explore their ever changing environment but mom still has to look for plants and berries and keep an eye any dangers and carnivores that are around. Dogs protect their own little ones in the wild and readily help to keep an eye on the human youngsters in the same way. Further more dogs will sound the alarm when needed. It's one more helping, important hand, that dogs bring to the bargain.

And it's not for the first time. This BBC article shows how best to keep plaque away from your teeth but no dentist or hygienist will mention it to you because, well you know why. People, mostly elderly, are literally dying because this knowledge is not being disseminated widely. Spread the word. (The first article about this technique appeared in BBC circa 1995.) [1]

Humans and dogs were two borderline species until dogs were domesticated. But together the two were so complementary, that they never looked back. The dogs had the speed, teeth, smell and baby sitting while humans had the weapons, rock throwing, intelligence and cooking. It was and is a killer combination that rose to the top of the animal world on earth so far.
Re:Honda and Nissan might team up against Tesla and other EV rivals
on Friday March 15, 2024 @12:01PM (#39717253)
Musk keeps talking about the $25k EV but I have a feeling he's sandbagging it and it will be close to $20k. I say this because Tesla now has all the tech to produce cars in the simplest and cheapest manner with slightly lower quality versions of the bits and pieces that are now going into their premium cars. Ie slightly cheaper versions of the motors, battery packs (smaller but fast charging), interiors, window etc. All in the form of a modern Tercel.
