This is the weirdest part of the article by far. And absolutely no explanation.

San Francisco had some of the heaviest lockdowns in the country, yet 100 miles east in Modesto the mayor actively defied the statewide lockdowns. California is a big state.

For last 20 years in the US, we have been recovering from decades of misinformation about the “dangers” of fat. The avocado is one item that benefits from a return to nutritional sanity. That shift has laid the foundation for items like avo

Check out Facebook’s Gorilla paper ( https://www.vldb.org/pvldb/vol8/p1816-teller.pdf ) which features some clever compression techniques for time series data generated at regular intervals.

Qatar is the highest in the world at 49 tons per capita per year. So you’re off by a lot. That doesn’t make 416 tons a lot by any stretch, but we are still early in the technology cycle for carbon removal/sequestration.

I don’t know if it’s just that complex 3D topology is hard or what, but those blue-yellow knot diagrams have never helped me understand a knot.

The article briefly mentions RPL. It’s a programming language for Hewlett-Packard RPN calculators. It’s an interesting curiosity if you’re in to niche programming languages. https://en.wikipedia.org/wiki/RPL_(programmin

They call this issue out in the docs specifically when the fat column is a sort/distkey. rsbb in the Intermix slack has studied this in the most detail I know of outside AWS but they haven’t published their book yet.

Cool! So if I select two columns with a predicate in the first, does it scan all stripes for the second column?

One of the gotchas of columnar storage (coming from Redshift) is that you lose all of the compression benefits if you have just one column that’s fat or hard to compress. In Redshift columns are stored in blocks. You want to fit roughly the

My mind just cannot visualize what zip is doing. I’ve written production code with zip and I’ve finished leetcode problems with zip. But every single time I need a piece of paper to help me through it. I’m fine with most of the rest of Pyth

Is there a reason that the copying process needs to be aware of how bytes are organized? Why can’t you just read the bytes from disk A and write those exact bytes to disk B?

The word “excessively” stands out like a sore thumb. Seems fishy to have a qualifier just on “violent” and not on any other term.

When you decide that a value N standard deviations away from the mean is an anomaly that must be investigated, you implicitly make an assumption about the underlying distribution of the data.

500k may seem like a lot, but it’s not in the context of the Mac App Store. Apple has sold over 100M Macs in the time this app has been around. Also, Apple’s policies are distinctly not driven by “if enough people are fine with it”. Apple’s

For my team, I decided we would go all in on Terraform for AWS resources. Lambda has turned out to be a particularly tricky one to fit into that mold. It took us some time to sort out where the “build” step lived in our deployment pipeline
