Except for the Ubers, everything you listed that was added, moves more people than cars do. Public transit, bike lanes, walkable areas provide viable alternatives methods of transit so you no longer need to use a car. And those cars have hu

Thanks for the kind words! For anyone curious to dive deeper into the crazyness that is quantum mechanics I can highly recommend a few resources: - Sean M Carroll's work, in particular his Biggest Ideas in the Universe books: https:&#

Superconductivity is fascinating. I don't know how people were able to come up with the explanations. Crudely, the reduced temperature means less jiggling of the metal lattice. This in turn makes it possible for the nuclei to be pushed

Yep! That's why I said it _sounds like_ a conspiracy theory. Just hope it can be halted in time.

The comment about an "email chain could have been a 30-second chit chat" is such a straw-man argument. On top of that, forcing everyone to commute up to an hour each way is a blatant disregard for people's personal time. How

Isn't that the opposite of the intended implementation? I don't write Rust, but I think your implementation will always return either `None` or the "fallback" value with the `"-default"` key. In the article, th

I see some confusion in the comments about C++ moves. I wrote an article in 2013 after it clicked for me: https://kholdstare.github.io/technical/2013/11/23/moves-demy... . It goes over motivation, how it

I think you missed his point completely. The point is that money removes the consequences of their and other's actions. Without this visceral understanding of the world, those people are not fit for power.

The other comments have mentioned the tools. On linux, there's good old perf. There's `perf stat` that uses CPU performance counters to give you a high-level view if your workload is stalling due to waiting on memory: https:/

To reiterate the other comments - 15 minute cities are about _adding_ things so _more is accessible_ within a 15 minute travel time, such as stores, schools, public transit etc. Nothing to do with restrictions. Check this podcast out for a

That is definitely not how USDC is set up. The creator takes 1 USD, and gives back 1 USDC and vice versa. In this case, some of the USD held at SVB disappeared, so Circle has less money for the USDC -> USD redemptions. There needs to be

This makes no sense. Circle's holdings are backing USDC. They can't use the money backing other USDC to buy more USDC. That's just market manipulation.

Yes! I almost forgot about market orders because trading firms never use market orders for this exact reason - you have no control over the price if things go bad. Most flash crashes are exacerbated by runaway market orders and stop orders

Yes. In my reply to the first comment I mentioned setting the opening price is "more complicated". Every exchange has their own system for the opening auction which you buy into when you list with a particular exchange. Most excha

Worked in HFT for a few years. The reason why most markets are not open 24 hours is more human, and just historical - aligned with people's 9-5 workday. There are also pre open and post close sessions of trading but it's much less

Really great article! Very well explained. One small inaccuracy is the claim that there is only one place for each stock. That has not been true for many years. In the US that was changed by https://en.wikipedia.org/wiki

Author of the article here - I completely agree. This text parsing problem came up because I was lamenting how many cycles were wasted in text processing. At my current job a text-based protocol from a 3rd party means around 80% of CPU time

The problem with that instruction is that to do 4 at a time you would have to multiply by 1, 10, 100 and 1000 respectively. The last multiplier does not fit in a byte.
