This post demonstrates with concrete examples how the standard deviation can be entirely misleading even for minor deviations from normality. Pragmastat recommends Spread — a robust scale estimator with a 29% breakdown point that remains reliable where the standard deviation fails. Confidence intervals are available via SpreadBounds . pragmastat.dev github.com/AndreyAkinshin/pragmastat The standard deviation may be an extre..

Large companies can have hundreds of microservices - some on Virtual Machines (VM) and others on Kubernetes, where new features are built and deployed every day. And, without efficient monitoring, it becomes hard to identify any specific application or critical API that’s failing. Let’s take the complaints automation system in a ride-hailing application, for instance. This system automatically solves complaints raised by the drivers and cu..

The fundamental idea with airplane design is not to design components that cannot fail, as that is impossible. The idea is to design the system to be tolerant of failure . Every part in the system is not “how can we make this part never fail” but “assume it failed. How does the airplane survive? - WalterBright, on [[Hacker News]]

UPDATE: Flat Habits now has its own page at flathabits.com . I've been wanting org to keep track of my daily habits for a little while. The catalyst: reading James Clear's wonderful Atomic Habits (along with plenty of lock-down inspiration). As much as I live in Emacs and org mode, it just wasn't practical enough to rely on my laptop for tracking habits. I wanted less friction, so I've been experimenting with building a toy app fo....

In March 1970, Dr. John Conway sent the “fatal” (as he later referred to it) letter to Martin Gardner. He was submitting ideas for Gardner’s Mathematical Games column in Scientific American. The New York Times features a good article on the fifty-year parable of The Game of Life. What’s appreciable, they asked some of Life’s most steadfast friends to reflect upon its influence and lessons over half a century. Among them, Brian Eno, who, b..

Beware of icy conditions on the trail. Last weekend’s snowfall is still present on the trail once you get a couple of miles from the parking lot, and while the snow isn’t deep, it has been compacted into slippery ice in many places. The parking lot and road are free of snow, so the actual drive there is no problem. The gravel road is in a good condition, with just the occasional potholes to watch out for. We arrived just after 10am on a S..

I’m a space junkie. So tonight, like all the other space junkies on the planet, I watched in awe as Perseverance seamlessly and beautifully landed on the surface of Mars. This is a phenomenal achievement. Of course, I will eagerly follow her 1 progress. As I was following the live broadcast, I wondered: What kind of hardware and software runs all this incredible technology? It was launched in 2020, so it must be some cutting-edge stuff..

Flat hunting can be a big pain - particularly for European metropoles. Most flat search platforms already offer good filter options but until now, I didn’t see any with custom geographic filters. Apart from drawing your own area of interest on a map, you seldomly find filters such as “How far is the next metro stop?” or “How close are important facilities?”. This article will show a quick and universal workaround for custom geographic fil..

WFH Day 340 During my lunch break, I took a walk and visited my friends who own a coffee shop in our town. Yesterday, they told me that they would get their vaccination today. I was amazed to hear that since my healthcare provider is sending me weekly updates about the actual vaccination progress and that they vaccinate people over 75. It looks like I still have to wait a bit longer since they don’t have enough vaccines for this age group.

I came back to reading Shirley Jackson almost by coincidence. I had just finished watching The Haunting of Hill House, and, as I always do with stuff that tickles my curiosity, I was doing a little research on it. That’s how I learned that the TV Series is loosely based on a novel by the same name written by… Shirley Jackson. Still imbued by the TV Series’s atmospheres, now knowing about its connection with Jackson, I was ready for anothe..

One of the immense difficulties I have faced while running production engineering-type teams is how much-unplanned work can drop into their daily workload. I am still trying to solve the root problem of why we get so much unplanned work but the first item on my list is to find a way to measure it first. Measure, then tackle is my go-to operating mode. Many engineering teams face the challenge of balancing planned development work with unpla..
