I played a long while ago and a string of similar incidents eventually made me leave.

I came back ~6months ago, and it was more chill, but still not great.

I will say that if you're in a group of 3 or more non-toxic people, you almost never get toxic players. Not only because you've only got 2 chances to roll low rather than 4, but also because they're more aware that probably won't get anywhere.

Does Payday have a singleplayer mode? I thought it was a multiplayer game.

a situation where your character would get killed for a bad dialogue choice.

I think this is a ridiculous thing to criticize too. Dialogue is important in a game like this and it has (sometimes lethal) consequences.

Imagine if this argument were applied to combat. It turns out that it is impossible to beat some encounters by role-playing a loner wizard who refuses to cast spells. Nobody in their right mind would actually believe that is a valid criticism.

So the Stanford post assumes that we continue to consume roughly 2% more energy per year. At that rate, in 1000 years we would go from consuming 1.753×10^13 W to consuming 6.98×10^21 W. This would be 40,000 times the energy the sun puts on the Earth. Because most energy quickly turns into heat, this would heat up the entire surface of the Earth to the point where it is uninhabitable. I feel that tidal locking would be the least of our concerns at that point.

Professor Liu seems to have made a simple mistake: What his model showed was unsustainable was not tidal energy, but actually his assumed exponential growth rate of energy consumption to ludicrous levels, levels that would spell disaster for the Earth.

That said, the website's math checks out. The linear approach is a very basic year 1 physics problem that can be quickly confirmed.

The values we need for this calculation:

The mass of the earth (M) is: 5.97×10^24 kg

The radius of the earth (R) is 6.37×10^6 m

The angular velocity of the earth (w) is 7.29×10^-5 rad/sec

The current total worldwide primary energy consumption is 1.753 × 10^13 W. This is pretty close to the article's assumption

The equations necessary:

The moment of inertia of a solid sphere of uniform density is: 2/5 MR^2

Rotational kinetic energy is calculated by: 1/2 I w^2

After some very basic plug-and-chug:

This provides a moment of inertia of the earth (I) of: 9.69×10^37 kilogram meters squared

And a total rotational kinetic energy of: 2.575×10^29 kg m^2 /s^2 This is pretty close to what the Stanford website calculated.

So if we used the suggested 1% here, it would take around 5.0 x 10^10 years to tidally lock the earth to the moon with our current energy consumption. But that's not what was assumed in the article. It was also assumed that we would continue to expand our energy consumption by a constant 2% per year. This requires basic calculus.

We have energy consumption that starts at the previously mentioned: 1.753 × 10^13 W

Below, n is equal to the number of years.

This leads us to a consumption growth formula of: 1.753×10^13 * 1.02^n

To indefinitely integrate that formula, we simply divide it by ln(1.02), which gives us: 8.85236×10^14 1.02^n (we will drop the +c because it's not necessary here)

And now we just need to solve the following equation for n: 2.575×10^29 = 8.85236×10^14 1.02^n

Solving gives us a real solution of: around 1681 years. This is close enough for me to say that the math checks out, considering that I didn't start with exactly the same base formulas. But ultimately this is besides the point. The math is right, but the premise of a constant 2% growth is ultimately unsustainable. Short of building planet-scale radiators to shed heat, the earth would become uninhabitable by virtue of the sheer energy consumption alone.

Even if the CEO of Wells Fargo loses your money, you will still get at least $250,000 of it back (assuming you had deposited that much) via the FDIC.

The FDIC will honor their obligations because to do otherwise would be to risk a massive bank run, of the sort that started the Great Depression. This wouldn't just screw you over, it would screw over the ultra-wealthy too, and we can't have that.

At the end of the day, someone can just not take your mattress money and you might be out of luck. Your mattress can burn down and all that money is gone, which is far more likely than Wells Fargo taking your money and then the FDIC not giving you anything.

Dwarf Fortress (before the Steam edition.) There was no in-game tutorial. I found a 2 hour long fanmade tutorial on Youtube, and even after that I had to learn a lot of stuff from the wiki.

At 16x, you will get 72MB/s read speed. My SSD has a 560MB/s read speed. Because of this discrepancy, loading a game from a blu-ray disc will take roughly 7.7 times longer. A 20 second loading screen becomes a 2.5 minute loading screen. This alone justifies the cost of keeping it on my SSD. Especially because if I want to remove it I don't lose permanent access to the game, I can download it again in a couple hours.

Hmm. I'm in a pretty small town. I think the most annoying thing is that we have two very nice river trails, they're obviously supposed to connect, but they don't. Both of them just stop before the highway. There was a planned underpass, but it was put on hold during COVID and our new city council seems uninterested in restarting construction.

As such, around 1/4 of our population can't bike or walk into downtown, they must drive. And I can't bike into work, as turning left on the highway is not gonna happen on a bike.

With how many people use our paths, we need much more investment into them. They're great for residents and they're a tourist attraction: we need to make them as easy to use as possible.

I always feel a bit weird when people ask me what I do in my own spare time and my answer is basically fixing my shit, then pushing it just hard enough that it breaks again.

And the percentage of homes for sale is quite small compared to the total number of homes. So if investors are buying even a few percent of the homes, that can still be most of the homes that are for sale.

I replaced my brakes last weekend. Did the pads, realized I also needed to do the disks and brake fluid too. Ended up being a lot more work than I wanted, mostly because I was missing tools.

eg wind generator parks take up a lot of space

Though the vast majority of this space can still be used. I live near a wind farm and the area under the turbines still is ranchland. There are cows just chilling under them. The wind company pays farmers for the land in a long term lease agreement: https://www.wri.org/insights/how-wind-turbines-are-providing-safety-net-rural-farmers.
