The problem is, you have so much speed that you keep missing.

So, yeah, bottom line: you only need a delta-V of about 12 km/s to get out of the solar system, but a delta-V of 30 km/s to get to the sun without going into orbit.
This is true, but the possibility of gravity assists mostly nullifies the difference. If you can get out to Jupiter you can basically choose: either let it sling you out of the system, or let it cancel out all your orbital velocity so you fall into the sun.
These are all technically correct but fairly inconsequential. Even just to graze the sun you need to lose 90% of your orbital velocity. And although everything orbiting the sun will eventually fall in, the friction is really low. It will take billions of years to lose enough velocity to fall in.
The problem isn’t even the hard drives, it’s how they are managing them. There’s not many digital data storage solutions around that you can dump into a closet for a few decades and then still read.
You have to regularly test your hard drives, so that when one fails you can take your other copy of the data and put it on a new drive.
Efficiency records involving perovskites are generally not that interesting without any longevity data. As far as I’m aware, the lifetime of current SotA perovskite solar cells is measured in weeks or months. That’s not commercially viable.
Not that efficiency research is completely useless, but the longevity is the real challenge that’s holding this up.
Sort of, yeah. Plant matter with lignins still partially decayed into peat. So it’s not exactly 50 million years of dead trees on top of each other. It’s more like layers and layers of peat, with still “fresh” trees at the top.
Note that although species can be described as tree-like, they didn’t quite look like modern trees do. Also, much of the world was swamp, and much of the dead plant material sank into these bogs and decayed into peat.
The amount of CO2 trapped during this period caused the atmosphere to be around 35% oxygen. This allowed life with inefficient respiratory systems to grow much bigger in size without suffocating, mainly insects. Think woodlice 6 feet long, spiders the size of dogs, millipedes as big as cars, and dragonflies as big as eagles.
Nowadays, trees absorb CO2 and produce oxygen, and when they die and rot the opposite happens, releasing the CO2 back into the atmosphere.
However, during the carboniferous period, when plants first developed the ability to produce lignin (i.e. wood, essentially) there was not yet any bacteria or fungus that could break this material down. The result is that when trees died they would kinda just lay there. For 50 million years, trees absorbed CO2 and then toppled over and piled on the ground and in water. Most of the world was swamp and rainforest. Millions of years of plant growth all dying and laying on top of each other
So much CO2 was turned into oxygen that O2 levels were 15% higher compared to today. This allowed some truly large lifeforms to develop: trees 150 feet tall, dragonflies with wings 13 inches long, millipedes the size of a car.
The trapping of so much CO2 led to a reverse greenhouse effect, cooling the planet, and eventually an ice age. The forest systems collapsed from the climate change (we think) killing about 10% of all life on earth. Eventually a species of fungus developed the ability to eat lignin, and cleaned up the dead trees that remained on the surface within a few generations. The millions of years of tree material that sank into the bogs eventually turned into coal.
Now we’re digging all that good stuff back up and are burning it, yay!
The reason for this is that git rebase is kind of like executing a separate merge for every commit that is being reapplied. A proper merge on the other hand looks at the tips of the two branches and thus considers all the commits/changes “at once.”
You can improve the situation with git rerere
I don’t know if phone call spam is only an American thing or something. In my country (and most of Europe) that stuff is effectively banned and doesn’t really happen.
Still hate getting calls though.
Are you talking about Binas? All the homies love Binas.
Reddit would become just another instance with no API control
Being that large of an instance gives a lot of api control all by itself. Theoretically Chrome is just another browser and member of WHATWG. in practice, if they implement something it immediately becomes a de facto standard. Reddit would be the same.
I wouldn’t bet on Huffman’s exit doing anything of consequence either. Reddit is now under the control of investors who want a return. One way or another, monetisation of users will increase.
In this case, it redirects to Google’s general privacy policy that covers all their services. Anyway Google’s calculator stores a history of all the calculations you did in your account somewhere. So I guess it needs to have a policy stating what they do with that data.
The Chromecast is a small $35 dongle that goes behind your TV. This new thing is a whole $99 set-top box with an AI integration. They’re not really the same product.
Kinda but Thunderbird is community driven, and spun out into an independent subsidiary.
Laura Chambers, who stepped into an interim CEO role at Mozilla in February, says the company is reinvesting in Firefox after letting it languish in recent years,
It’s sort of amusing to me that Mozilla would let the Firefox browser languish. Is that not the raison d’etre of your entire organization? What are you doing with your time and effort if you are allowing your core product to languish? What would people say if Microsoft said “yeah, we’ve allowed windows to languish in recent years.” What an insane notion.
These are gonna be hella expensive for a while. If space is not a concern there’s much cheaper batteries out there. You don’t really need fast charging capabilities either.
Pi Hole couldn’t block YouTube ads last time I tried it, which is one of the main things I want to have adblock for. So I went back to ublock origin.
