Thanks for the clarification. I didn't see it in the article.

Interesting and well-written article. Thanks to the author for writing it. Replacing Spark with these single-machine tools seems to be on the hype, and Spark is not en vogue anymore.

The author ran Spark in Fabric, which has V-Order write enabled by default. DuckDB and Polars don't have this, as it's an MS proprietary algorithm. V-Order adds about 15% overhead to write, so it does change the result a bit.

The data sizes were bit on a large size, at least for the data amounts I see daily. There definitely are tables in the 10GB, 100GB, and even in 1TB size range, but most tables traveling through data pipelines are much smaller.

One of the authors has responded to the comment:

> The Supplement section of the letter states that the study was conducted from February to October 2020. The year reported was an error; the study was conducted in 2021. The Journal is in the process of correcting this error.

Quite the opposite. Covid is dangerous for elderly and people having severe medical condition, much, much less dangerous for young and healthy. Flu is more dangerous to young people than Covid.

Flu also causes hospitalizations in comparable amounts to Covid[1]. Note that we have a vaccine for flu, and it is still causing almost a million hospitalizations in bad seasons.

I can confirm this.

I got a really hard pneumonia few years ago. It took several days in hospital to find an antiobiotic which actually worked, and I was in pretty bad shape in ER when it finally started to work.

It took 10 weeks to recover back to work, and over a year before lungs were back to normal, confirmed by x-ray.

Pneumonia can be deadly, even for healthy young adult.

I read your entire comment history couple of weeks ago.

Great experience! Thank you for providing level headed and well articulated responses to the widely spread mass hysteria.

I also learned a lot, special thanks for pointing Thomas Howell's books. Reading now the 'A Conflict of Visions'.

And from the same report:

"However, these masks would provide the wearers little protection from microorganisms from others persons who are infected with respiratory diseases. As a result, we would not recommend the use of homemade face masks as a method of reducing transmission of infection from aerosols."

Completely agreed! Excess deaths are reaching all time lows in many European countries. Most of the excess deaths - as in Italy - were probably due to antibiotic resistance.

But this is something you can't say, not at least in HN. You have to agree and obey the official truth.

It is mind boggling how otherwise sensible people panicked and refuse the see the truth. I really hope vaccine would come soon, just to calm people down.

Exactly! But you are not allowed to say this.

I've found the same. It sounds great and applicable but could not find any practical application with real data.

Even when applied to large number of real companies' journal entries, the amount of false positives is overwhelming.

Thanks!
