This really sucks when you spent 45 minutes constructing a thorough reply.

 

Sometimes when you hit reply, it doesn't save. Then you go on to do other things and everything you wrote is lost. Sometimes you have to hit reply 2,3 or even more times for it to actually do it. This is complete insanity and bad UX.

Definitely agree.

Let's fix this with incremental reforms

I'm not familiar with pictrs and how it works, but software I wrote which contains thumbnails and full copies of every image on the fediverse along with fingerprints, full database metadata, etc, doesn't take up even a tiny fraction of that space. So...

Lowlights from the video:

it starts with "plants don't want to be eaten so they generate chemicals that can be harmful to you" 🤡😂 as if animals want to be eaten 🤦

It ends with "plants have non protein amino acids, which could trick their way into passing the blood brain barrier and act like prions. There's no studies to back up this theory but..."

🤡🤡🤡🤪

It uses peltier effect, which isn't very efficient. There are more efficient ways. Also, personal peltier coolers are really old tech. The article says Sony incorporated their cell phone heat dissipation technology, which means patents. But overall it seems like good product design with mediocre tech.

Using it outdoors probably isn't too bad. It can remove heat faster than skin can conduct heat from the air, and faster than sweat. It can also help during all these wet bulb weather events that are increasingly common.

As far as battery usage, I can't find anything on capacity. They say 100 minutes charge, commenters say it lasts about 2 hours on full charge. Given the size it's probably similar to a cell phone battery. A blurry image I found looks like it says 1.5 amp charging rate. This would put energy usage at around 5 watts with a smaller than average cell phone capacity. According to physics Substack, people generate around 3 watts of heat at rest. So it is just powerful enough to cool you. Also why it says only "light exercise" in the ad copy presumably.

As for energy efficiency, it's actually probably very environmentally sound. But it has lithium ion batteries, plastic, integrated circuits etc. So in that sense, not so great.

Also it's best use case is for riding mass transit to work. Working from home would be so much more environmentally sound.

 

Dumbest carny bullshit I've ever heard

I think the reason they are considered similar is the usage of Double Ratchet encryption.

Right? This is what always gets me about 'public square' arguments. We have that. It's called the Internet. Corporate honeytraps are not anything special or unique, other than there's billions of idiots dumb enough to get caught in them.

I just noticed the graphic "4 shape of river is permanently altered". Who wants to take bets that the only reason they care is because it affects some asshole's riverfront property?

And they dunk on India for all the parasites in Ganges.

Lol true. I would hope that wet wipes are not being used to wipe asses but I was referring to civil engineering: removing solids from wastewater is possible. It says more about UK civil engineers than it does about careless citizens.

The things people flush is insane. It is a solvable engineering problem though.

 

 

Recently the US government has announced that 12 billion in funds will be used to "modernize Puerto Rico's grid" with special attention to "their local economy", and complete with a promise of 100% renewable sources by 2050.

Previously, due to provisions in disaster relief funding, they had said that they would only repair the existing coal and petroleum based grid and not allow funds to be used for any changes or upgrades.

They also promise that somehow this "modern" grid magically won't go down with the next weather event or earthquake.

So this is a win, right? Not so fast. Let's take a look at a different way for a moment. There are 1.44 million households in PR. A 1500 watt solar and wind hybrid energy system complete with battery and inverter is available on Amazon for $2000 retail. This is enough to power any home less than 1200 square feet, even if they aren't insulated. So for only about $3 billion, every single home can have their own individual "100% renewable" power system that can't be interrupted due to a weather event or earthquake. That's based on retail and not bulk pricing. For another $2 billion, every single house can be insulated, assuming none are currently, reducing the energy needs. For another $1 billion, each household can be provided with a heat pump, assuming none have air conditioning or heating currently. So for a total of $6 billion, half of what the grid would cost, every single home in PR can be retrofitted to be energy efficient and use 100% renewable energy. Tomorrow, not by 2050.

Let's assume we can do the same for commerce and industry with the remaining $6 billion. Hell, even if it costs $20 billion, wouldn't that be better than another stupid grid?

On my new phone, OnePlus with Android 12, the incoming call UX is abysmal. There is a circle with a phone handset in the middle, with white chevrons indicating you can swipe up or down. Somehow you are supposed to guess that up means answer and down means decline. On my old android 11 phone at least there was a green icon for answer and red icon for decline, but it was still swipe left or right. What is it with these asshole interface designers who think that left/right or up/down has some universal meaning? Fuck these people.

 

For example, there is a cable from my monitor to my desktop that when plugged in straight is able to be disturbed or dislodged from my dog walking past it and the hairs on the top of his tail touch it with micronewtons of force. Yet if I coil it just 3 turns over 3 feet length it can withstand 10000 times as much force before becoming loose.

Another thing I'm reminded of is the coils in phone cords back when everything was wired with handsets. This must be a well known principal but I don't ever remember learning it.
