This isn't really true, some languages handle I/O much better than other languages. We migrated a Python application to Go that was about as simple as you can get and mostly blocke…

There's an important nuance there which is that they don't have to prove that the person knew the actions they were taking were illegal, just that they intended to take those actio…

You can only run Uber with <100 engineers if you cut out a substantial amount of the systems Uber requires to actually function as a company. Goodbye Fraud, Risk, Safety, Insurance…

This is not the case, removing dams still can come with huge benefits to the ecosystems those dams disrupted: https://www.mercurynews.com/2019/05/08/four-years-after-cali...

If this still builds a dam, doesn't this have the same environmental concerns as any hydro project? Or is there something that makes this less of a concern?

Yup, that's a lot closer to the kind of numbers I would have expected. And if you look at peak it's probably at least 10k tps for each of them.

That doc is from 2013, so it's pretty out of date.

I can pretty confidently say that all of Visa+Mastercard is way more than a few thousand transactions per second, I'm familiar with several companies that push hundreds of transact…

DC and LA are both infamous for having bad public transit systems, so don't base all your decisions on your experience there. Within the USA, Chicago is really good - taking the L …

That may be the case for LA, I'm not familiar enough with their situation to speak to it, but it isn't the case generally. There are lots of rail lines in the US and globally that …

Building an entirely new bridge isn't going to be cheaper than adding more cars to BART. Even assuming it was (which it wasn't), it's not going to help as much as you think it is. …

> Sometimes you just need a wider road. Pretending that's never the case is preposterous. If that was true then why do we keep multi-lane highways open instead of closing all but o…

Yup, this is a big reason why I said "in most cases" and not "in all cases". When your trains have to go underground and underwater and your highways go over roads and over bridges…

It's not correct that cities look at road throughput with no concern for how long that travel takes. The success criteria that city planners use always includes travel times which …

The way that public transit scales to meet higher demand is different than roads. Whereas roads require more lanes, public transit such as trains can scale by either adding more tr…

It depends what your success criteria is. It's true, you've successfully increased the throughput of the transit network, but you haven't done anything to improve transit times - y…

It really depends on the company. Companies like Google and Facebook are very unlikely to hire people at a higher level than their previous level (though certainly it happens). Tha…
