This is such a cynical outlook on the world. Of course there are for-profit companies -- most I would argue -- that have a positive impact on the world, and Tesla is one such example.

R + the tidyverse (dplyr, ggplot2 etc.) is easily the most elegant data analysis combo I've used. However, I tend to use Python for this usecase nowadays, primarily to reduce friction when working with others where Python is the lingua

This is very cool. Relatedly, as a data scientist, I wish companies would expose their APIs through SQL. I've spent a lot of time pulling data into ETL jobs from things like mixpanel, adwords etc., and having a unified interface would

Agreed, with modern reactor designs nuclear "waste" is a misnomer. The Dutch keep all of their nuclear waste in buildings open to the public for tours, buildings which also happen to house priceless artwork: https://www

I think the fact that binary size has become smaller rather than larger is notable in a world where most other software seems to be increasingly more resource hungry.

The problem with vertical farming is where does the energy come from? An acre of solar panels is not capable of supplying enough energy to grow an acre of crops, even with the efficiency gains we've had in photovoltaics and lighting wi

It seems you misunderstood the article. When a minority has an intolerant stance about which the majority has no preference towards, the minority wins. For example, the majority doesn't care if all food is kosher. But, the majority wou

I agree, the lack of stack traces can be annoying when debugging Go programs. Instead of returning raw errors everywhere, the problem can be alleviated by adding some context to returned errors: if err := foo(x); err != nil { retu

Dropbox have a good real-world comparison [1] between BBRv1 and BBRv2. They found the retransmission rate to be 4x lower for v2. It's on their edge network, so would be interesting to see how v2 performs on connections with a high band

Thanks for your response! This technology is very exciting. Since you're targeting WASM there's a whole host of possibilities. Python is already supported through Iodide [1], but I imagine other languages could also be ported, and

Congratulations on the launch! I've been excitedly waiting for the public release since hearing about HASH on Joel's blog a few months ago. I've been playing with some models over the past few hours and I have a few questions

This is interesting. I haven't seen much in regard to comparing TCP+BBR to FASP other than a masters thesis which suggests FASP outperforms on transferring large files over long distances (which is exactly its intended purpose). But,

My understanding is that the protocol underlying Aspera (FASP) uses UDP for the main data transfer and a TCP connection for coordination. By using UDP for data transfer it's not restricted to the ACK ranges imposed by TCP which can hin

How well does QUIC perform over networks with relatively high packet loss? It seems like Aspera ( https://www.ibm.com/products/aspera ) is the industry standard for high performance WAN transfers, but it's a proprie

You want to make sure PyCharm is only indexing files within your project. Depending on your setup, it can try to index all files within virtual environments etc.

Not only sub-optimal, but unsuitable. Use algorithms specifically designed for password hashing: argon2 / scrypt etc. SHA256, SHA512 and Blake* algorithms are suitable for secure checksums and HMACs, but not password hashing
