What do you think it’ll mean for birth control? I don’t know what’s in the pill right now but I can’t imagine it being outperformed by a plant? But I speak from ignorance here.

Uncharted territories for sure. I wouldn't be surprised if we're gonna see a few bumpy moments in the next months. What happens when the network is back under serious load? I thought I knew the old PoW system well enough to know what might happen, but I still haven't fully grokked where we're at now. To some degree nobody knows the new balance but I feel like my level of understanding of Ethereum has declined in the past years as the tech has become more occluded. Is it just me, or does it seem harder now than before to fully understand what's going on without resorting to black boxes? There's Staking 101, Staking 502 and Staking 604 but I haven't yet found resources that cover the inbetween steps.

    Ethereum got kicked in the nuts earlier in the year and it's only because the "experts" doing the talking are business majors and armchair dipshits who lack the curiosity or drive to even figure out what the fuck is actually going on.

Adding to that, they might have gotten bored of this space now that we've been in a bear market for a while and they don't have free time to spare due to lockdowns.

    You buy a bond, you get a guaranteed return. You can buy and sell that return, you can option that return, you can future that return, you can do all sorts of crazy shit to that return, but it starts with a guarantee. It's a process with a three hundred year history backed by military force.

I keep forgetting that the fundamental innovation behind crypto is its ability to create trust from algorithms (aka thin air). Considering there is nothing but a vague promise, it's a small miracle that there are already 420,000 validators each putting 32 ETH just on that promise.

Is it fair to compare the returns to the US1Y and conclude staking returns are being overtaken at a rapid rate? I'm expecting the staking pool to diminsh when people can finally access their stakes again at $future_date, but I'd be surprised if the APR would jump high enough to catch up to inflation and bonds by the time that happens.

Funeral of a wonderful, hopeful and passionate cousin today. She died far too young, too quickly and left behind too many. If you do anything today, show someone you are there for them because one day you might not.

The new home is fan-tas-tic. The neighborhood is quiet and green, we now have a GARDEN which is lovely (even though it'll stay 90% bricks until we tackle that project next year), and I get to bicycle everywhere through lush parks. After a lot of work, most of our stuff and furniture is now where it needs to be. The only two downsides are that money is evaporating at unforeseen rates and that the previous owner was good at fixing up rooms? But his pipework around the boiler was described today as 'dangerously amateurish'. $300 just to fix it so it's safe to operate...

Opened my work email today for the first time in 5 weeks. I did a good enough job of handing shit over that I had 250 emails to breeze through of which only a dozen still require action.

Is it though? I mean, the woman itself is eerie, but my understanding of the way these AIs work is that the opposite of a bunch of prompts could have also been anything else. It just happens to clump the traits "woman, brown hair, pronounced cheekbones, horror" together in a negative corner.

Personally I am much more terrified of the power that these models give to people to do awful things. Disinformation campaigns, online harassment, scandal fabrication, you name it.

How badly do you want to learn SQL? Because this is just "visualize SQL queries on crypto data" with all the annoying and difficult data prep steps taken care of.

What a fascinating tool to exist. I considered toying around with a BigQuery blockchain copy but this seems miles easier if I ever have questions about trades and/or the blockchain itself.

Glad to hear you're still alive and kicking, pabs!

I don't know how far back you'd wanna hear, but in the past years I got out of college and into my first job where I'm now working on all sorts of sustainable mobility consultancy projects. My schtick is crystallizing into "how can we use data analytics to make better mobility systems". Did a bunch of work around EVs and moving more into shared mobility recently. Together with one other colleague, I created the model to predict the Dutch fastcharging network demand for the next decade that will be the foundation of a lot of plans in the next year's.

I found the love of my life. She moved in February 2020. We weathered that storm well and have just bought our first home, which we've been moving into for just a few days ago. It's fan-tas-tic. I'm writing this from my phone while on holiday with her wonderful family in the south of France.

This year I also got a bout of long COVID in early March, which is now 90% gone but not 100%.

Oh I forgot my Hyundai is also a shared electric car that was in my neighborhood, that I just reserved through an app. Really, car rentals are d e a d and good riddance.

I'm off for three days and you guys start talking about EV charging. Literally doing 1200km in two days in a 66kW Hyundai. A few points to add to the discussion:

1) you charge where you park. You top up in quick breaks when you need to go further. Nobody wants to fastcharge, so we expect it to become a much smaller part of driving than gas stations are now. Over here we expect just 13% of all EV charging to be at (highway) fast chargers. Imagine if you could fill up your car with water. Would you really opt to fill it up at a random industrial parking lot you could also drop a hose in it on your own driving lane and at work for half the price? How about your employer realizing they could make money by offering you free charging when you allow them to use your car as a battery storage? Opportunity charging, which is that you charge when your car is standing still anyway, is the inevitable way forward.

2) The US is dearly lacking in both fast and destination chargers. Range anxiety disappears once those two are remotely reliable - I know this from first hand experience and from a bunch of studies done on the Dutch charging station network, which happens to leave every other country in the dust. As soon as it's a common sight for there to be a charger in a parking lot, people stop complaining. Because I already have the luxury of a dense and reliable network of destination and fast chargers, I almost never have to worry, and I also almost never fastcharge. Colleague of mine has a charger at home and at work and he's never even used a fastcharger. Because if you leave full and can charge at your destination, that's two charging stops eliminated. So a <car range> mile trip both ways is made possible by just one charger at my destination, that happens to also be a decent way to make money for businesses with a large energy connection. Tesla drivers love their Superchargers, but normal people will avoid them if they can. And if you do need them - for most people, as soon as your EV can do 100+ kW of fast charging, which is "most new models and probably whatever first model upper class people will buy", nobody minds the stops because you'll be ready to drive another 150-200 miles right when you're done taking a piss or grabbing a coffee. Especially when you factor in that charging is cheaper per mile than gas.

3) What will drive the change in chargers? Well, the business case for EV destination chargers is decent. The case for rapid chargers is VERY good as soon as you hit a certain level of daily users. There is less overhead and less insurance than a gas station. It never needs refills, and you can basically just plop one down and wait for your investment to pay off. Even a small station can draw traffic, or can boost sales. The number of rapid chargers that aren't Tesla has doubled in less than eighteen months over here. We fully expect every supermarket, DIY store, McDonalds and Starbucks (any place that you will park at for more than 20 minutes and that owns the land it's on) to follow suit.

4) Smart charging capabilities have been made mandatory on all public slow charging stations here. The collective energy use of EVs will be a hit on the grid, but it's in the form of "small spikes in many places", which is something that grids are in theory perfectly capable of handling if dimensioned correctly. The real problem that will fick things up are heavy vehicles. They consume a factor 10-15 more energy than cars per km and require near 1MW chargers if you want to top them up along the way. The energy use of industrial zones can easily increase by TWh's if adopted widely, which is not the case of personal vehicles. And the TCO, which is nearly always the main driver of any EV adoption rate, however is good enough that the trucks will be here before the infrastructure is upgraded.

5) I still dream of a V2G system of energy brokerage whereby we can delay daily power use with cars and home batteries. The realities are complicated, and the rise of EVs seems to be going just a bit too fast for V2G to catch up. My city is one of the first to realize what you guys are theorizing about.

But it's the result of one incredibly entrepreneurial dude who's been at this problem for 8 years. Wider adoption... I don't know. I hope so.

Just drove to Reims today. Next stop on our trip to South France is the Taize community, which I've heard great things about from my SO who's been there a few times now. I'm expecting a Bible camp version of Burning Man.

Note to self: never ever plan another 12-day-in-a-row move again. The human body is not designed to lift weights for six hours every day at >30C temps without any training. We made it though, so now it's time for a well deserved holiday.

This might already be too late, but supposedly it helps to combine a sedum roof with solar. Lowers the temperature of the panels and the shade improves the life of the green roof.

Personally I'm really really happy I managed to find what is probably the last three year fixed price energy contract in the country. Yesterday my old electricity contract got another 51% price hike, so I feel like I'm dodging a bullet.

I'm was on the fence on whether I also want to drop 2K on a doom prep electrical heating split unit system just for the living room. But consumers will be hit last and if I can't get gas anymore I probably have bigger issues than a chilly couch.

Two minutes too late for me, pubski.

I’m sure he’s the kind of person to never ponder why the whole college dropout thing never happens in aerospace startups.

Thanks, I now have a new fear of carbon fiber. Just checked and thankfully my recently acquired bike is made out of aluminium.

I’m also now morbidly curious what might happen to the i3 a few years down the line, as it has both a shit ton of carbon fiber and zero bolts.

We’ve been moving homes for the past days. Instead of the usual weekend mad dash, this time around it feels like I’m marathonning as we’ve been busy with the move all day every day for the past week. It is exhausting, especially with some last remnants of long covid tiredness, but it’s slowly all coming together. We put in a new laminate floor in over the weekend, which immediately made the living room warm and cozy. Yesterday we moved and assembled the bed and couch. Today the kitchen got all of it’s stuff and the living room got the bookcase set up. At this rate of about one van full per day we should be done by Monday!

    But the Physics of Spinlaunch is good enough for The Brothers Yaney to gain the backing of New Mexico political leaders. Once NM politicians were reeled in, then the big investors follow again by more politicians. So far, The Brothers Yaney have secured $110 million in investor support and now $2.5 million in additional state money.

these mofos are getting 110 mil on their second round of bullshit and I'm the one with imposter syndrome??!?
