this is a really weird competition. I know of many desks still using excel to run/update models which are almost always consumed by human traders. This is a very antiquated and generally fragile system that has a very steep learning cu

I can't even log in because they want to text verification codes to phone numbers that have never been associated with me (maybe they're old work cell numbers?)

Maybe you misread the article. Plant protein is inversely correlated with mortality in middle-aged adults. They focused entirely on patients with a mean age of 75 years. regarding the group they studied "Plant protein intake showed no

I do not have access to the article so difficult to say but they do specify "community-dwelling" which I believe means they were in something like assisted living facilities. This would make data collection on food intake much eas

I don’t know what you’re doing on a 4GB machine but I promise most workloads that create significant memory pressure would start creating problems for you, just like on macOS. I use a dual xeon, 64GB Linux desktop which performs reasonably

Only natural that complexity is increasing. When and where that’s warranted will be an eternal debate.

Except this time it's a bunch of "data scientists" that went through bootcamps or one year masters programs and have zero understanding of the market or trading.

BlackRock entered the market as a landlord all the way back in 2011. They are fine. Not only that, they have real investment knowledge. Zillow and OpenDoor are a bunch of amateurs that thought they could turn "data scientists" int

The 10x programmer discussion feels a bit silly partly because it’s on the wrong scale. The real scale is more like this: In a specified amount of time, N, what is the conditional probability that the engineer, e, can design and code a solu

This is a ridiculous critique of the argument. Just because everything can’t be quantified doesn’t mean we can’t quantify some things. I worked in quant finance for many years so I’m very familiar with low signal to noise in complex systems

While this sounds truthy, would be even better if you have refs on what's been stuffed in.

This is only true in states with non-recourse loans. Many states have full recourse home loans that would require the homeowners declare bankruptcy to "walk away"

I’m not a UI/UX expert but here’s my 2¢ from limited work in this area. It depends on the type of animation and the platform. A fade in that’s 250 or even 500ms can be a nice effect on mobile when it’s not blocking other interactions.

I purchased a 1Password license years ago. I knew when I bought it that major version upgrades were not included and my feeling was that I would rather have a subscription so I could just seamlessly upgrade when new versions arrived. Ever s

I’m curious, what is currently the most promising carbon capture methodology that’s actually scalable? Already in use or ready to use, so we can exclude research projects with no path to mega-scale

The heads of departments are political animals. This is purely a damage mitigation strategy. If we give them more credit than they really deserve, the department and IRB were severely negligent.

The Japanese buildings are absolutely not energy efficient. They are horrible in terms of energy efficiency and durability. Not to mention, the homes in this article represent something like 0.01% or less of actual Japanese prefab homes. Mo

Unfortunately, there’s no shortage of obscure public investments where people can lose lots of money. Options are a classic example. Leveraged ETFs are another. There are many more. The idea that the SEC should limit access to hedge funds,

"buying crap" is a wild exaggeration. The Fed is injecting liquidity into markets where credit ratings are creating second and third order effects that will result in liquidity crunches. To make this clear with an example...many b

You are missing the point of credit cards vs long term loans. > The main reason people don't use credit cards to buy houses now is due to the credit limit. suppose you want to buy a $500k home. You go to a bank and they offer you 30

This argument is tough to swallow. The real push to build interstate highways was in early 1950s and began in earnest in 1956. National defense was only one piece of the justification for the project.
