1. On the chart of energy density, I'd like to see the the energy density of petrol for comparison. It's much higher, and even though extrapolation is dangerous, I'd like to see how long it could take to reach parity given some of the different forecasting models they mention. Specifically regarding their mention of air travel, I'd like to know what the minimum viable energy density would be for a vessel's fuel source, because my current understanding is that commercial air travel powered by electricity is not feasible.
2. They mention S-curve adoption, but that reaches a horizontal asymptote eventually, it doesn't go up forever. I'd like to see more analysis on where we think we're at on the S-curve, and why. I'd like to see a guess on where it levels out displayed on that chart, instead of the arrow simply pointing at the sky. If nothing else, show where the chemical limit might be based on current battery technology.
I want to displace fossil fuels and reduce pollution and slow the greenhouse effect as much as possible. I think transparency and realistic expectations need to be part of the transition. The more information available to markets, the more efficiently they can work towards the goal. I find it very difficult to get answers to these types of questions when discussing renewable energy generation and storage. I'm sure part of it is my own ignorance on where to look, which is why I ask: especially here, hopefully an expert can see this and quickly point me in the right direction.
If you can find a home you like more than places you can rent, and the payments are similar enough, seems like it’s still better to get a mortgage.
A mortgage payment can’t increase like rent can and most likely will, forcing you to move every X years if you decide you can find somewhere more affordable.
Of course there are tradeoffs in the other direction, like if you need to move to a distant location for job/family/health, I just don’t think it’s as one-sided as you present it.
Current front page items include a paper on vector databases, an example of AI garbage that showed Amazon in a bad light, a quite in-depth treatment of “Trilinear Point Splatting for Real-Time Radiance Field Rendering” hosted on a PhD’s own github page, you know github, a huge gathering place for hackers to share their code with each other? An article criticizing Unity about banning an open source LGPL application, written by a developer of said open source product, introducing a competing platform to further decentralize the app store landscape, an article critical of Boeing, an article critical of Apple, a radical rocket design, bluetooth mesh networking, an open source python notebook project, an indie developer’s project to run stable diffusion in an iOS app instead of from some corporate server, an article on the ethics of immersive tech, an article on mysticism and empiricism, an article on epistemology…
Yeah, real dull business environment here. I’d totally rather go back to my training on peer performance reviews.
If you can’t find anything interesting on this site, it is a you problem.
"If you run into an asshole in the morning, you ran into an asshole. If you run into assholes all day, you're the asshole."
We’re all so sorry that you can’t just do whatever you want while unleashing the externalities on society at large. You want to hack, go do it in your basement where you can’t affect the rest of us. You want to engineer, you have to answer to more people than just your mom asking what you want for dinner.
The salaries of the people who work on those projects are paid by the revenue streams generated by the companies.
Then there’re the square terminals that are normalizing up-front tipping for everything, not even just food service anymore. I’m sure I’m not the only person who has tipped up front for something and the service wound up being terrible. So there are three examples of tipping towards the future.
There’s another future component to tipping: in many places there is regulation that states if the tips don’t make up the prevailing normal minimum wage, the employer must pay the difference in salary. I’ve personally never seen this happen and I worked for tips for about 7 years.
But that wouldn’t be a wise use of time in my opinion. And that’s what they’re ultimately driving at: we all have limited time to expend, so do it in things that matter to you. I believe “matters to you” is a bias.
How many times have innocent people been wrongly convicted? The innocence project found 375 instances in a 31 year period.
How often do LLMs give false info? Hope it never gets used to write software for avionics, criminology, agriculture, or any other setting that could impact huge amounts of people…
I’m talking about a take home code challenge. It’s unreasonable to have someone to record a video that could last an hour or more. And I’m not gonna sit and watch that.
