Backblaze Drive Stats for 2024
(backblaze.com)
As of December 31, 2024, we had 305,180 drives under management. Of that number, there were 4,060 boot drives and 301,120 data drives. This report will focus on those data drives as we review the Q4 2024 annualized failure rates (AFR), the 2024 failure rates, and the lifetime failure rates for the drive models in service as of the end of 2024.

Computing Tricky Probabilities Using Model Counting
(msoos.org)
Probabilities of certain events are really hard to estimate sometimes. Often, it’s because we lack information of the underlying causal chains, but sometimes, it’s because the causes are so intertwined that even if we know the underlying probabilities of certain events happening along with the causal chains, it’s still impossible for us to untangle the web.

Lots of driving is proof we have a healthy economy: Misuse of VMT and GDP charts

Motordom's defenders will frequently overlay vehicle miles traveled (VMT) and gross domestic product (GDP) as if the story must be "more driving equals more prosperity."

Harold Eddleston, a seventy-seven-year-old from Greater Manchester, was still reeling from a cancer diagnosis he had been given that week when, on a Saturday morning in February, 1998, he received the worst possible news. He would have to face the future alone: his beloved wife had died unexpectedly, from a heart attack.

Kelly Can't Fail

You may have heard of the Kelly bet allocation strategy. It is a system for correctly exploiting information or bias in a gambling situation. It is also known as a maximally aggressive or high variance strategy, in that betting more than the Kelly selection can be quite ruinous.

A common pattern I’ve seen over the years have been folks in engineering leadership positions that are not super comfortable with extracting and interpreting data from stores, be it databases, CSV files in an object store, or even just a spreadsheet.

Why probability probably doesn't exist (but it is useful to act like it does)

All of statistics and much of science depends on probability — an astonishing achievement, considering no one’s really sure what it is.

Maximum likelihood estimation and loss functions
(rish-01.github.io)
When I started learning about loss functions, I could always understand the intuition behind them. For example, the mean squared error (MSE) for regression seemed logical—penalizing large deviations from the ground-truth makes sense. But one thing always bothered me: I could never come up with those loss functions on my own. Where did they come from? Why do we use these specific formulas and not something else?
