When Giulia came home from school today, she was anxious to tell me what she learned about a Viking King and his legacy. She told me the story of King Harald Gormsson, who ruled Denmark and Norway from c. 958 to c. 986. Harald is mainly known for introducing Christianity to Denmark and consolidating his rule over most Jutland and Zealand. However, what sparked my interest is that Harald was nicknamed “Bluetooth”, and, in 1997, the Bluetooth..

I'm a casual vim user (mainly nvim these days). One plugin for vim I find essential is fzf to quickly find any file in my current project. Recently, I was debugging a graphql query and I needed to search a JSON file for a snippet of text. Alas, the JSON was on a single line and on a remote server. After a quick search, I found this magic command line to format the JSON file and preview the result: jq -C . data.json | less -R Th....

My last performance of Intermedia Workshop was in May 2003. In it, I showed the 1954 school psychology film, “Facing Reality”. an informational film about “when reality seems too difficult for us to face, we retreat behind defensive mechanisms.” There’s a scene in a high school class where a boy named Mike is is being peer-pressured […]

I stumbled upon Modulations , a documentary on “the evolution of electronic music and its many genres. How the wide range of styles and scenes formed through experimentations on sound formation.” This short film (75 minutes) is packed with guest stars of all calibers 1 , some of them genuinely pivotal to the evolution of electronic music. Indeed, the uninitiated mind gets to know a lot of details and amenities on the first decade or so o..

This post derives MAD bias-correction factors using the trimmed Harrell-Davis quantile estimator, refining finite-sample behaviour further. Pragmastat recommends Spread — the Shamos estimator — as a more efficient robust scale alternative. Confidence intervals are available via SpreadBounds . pragmastat.dev github.com/AndreyAkinshin/pragmastat The median absolute deviation ($\operatorname{MAD}$) is a robust measure of scale....

Let’s talk about a very useful function: the NFC tag reader/scan on the iPhone. It would be great to have a simple tag placed, for example, at the home entrance, to turn on/off the lights using Shortcut. Yes, it would be. But it is not . Because the NFC tag reader paired with the Shortcut app, it’s almost useless because: It requires you to have the iPhone unlocked: First point, you must have the phone unlocked. That’s stupid be..

On a January day in 1964, something remarkable happened: Simon Wiesenthal took the afternoon off. He parked himself at a table on the terrace of Tel Aviv’s Café Roval, soaking up the sunshine as if he wished to bottle it. The friend he’d come to meet was late, but Wiesenthal had no reason to complain. He was still lounging with his drink and his reading when the loudspeaker crackled to life over the murmur of café chatter. There was a ph....

Solution to visit metro stations Here is a quick look at my solution to visit all the metro stations in Paris in one day. The trip start with Château de Vincennes on the east side of the map (start of the line 1). Route time: 830 minutes. For now, this does not display the route with backtracing. Instead, it assumes you'll choose your own shortest path back to the next step on the journey. Code at ewalk153/onedayinparis . I'..

What is Celery From the official website: Celery is a simple, flexible, and reliable distributed system to process vast amounts of messages, while providing operations with the tools required to maintain such a system. Wikipedia says: Celery is an open source asynchronous task queue or job queue which is based on distributed message passing. While it supports sch....

You are programming a tool in C++. Not a huge tool, not a tool where you care enough about performance to say, use faster data structures than those provided by the standard library, but one where you feel compelled to add some useful options. After a brief and uninspiring survery of the field you settle on the old standard for implementing program settings, you’re going to parse argv. Parsing command line options falls into the nightm..

In this week instalment, professor Devereaux takes on the different applications of blockchain technology as seen from a historian’s perspective. Really, this is less about the technologies themselves and mor..

The still experimental feature of CSS container queries allows us to make child elements listen on the current layout state of their parent element via pure CSS declarations. With the recent implementation of Google Chrome's experimental flag for CSS container queries we're now able to play around with this upcoming feature and already get some insights into it.

Passkit is very up-front that they are not a CRM and strongly suggest using their API for integrating with outside systems, or for editing pretty much any data. To kick the tires, we set up some very basic scripts to connect to the Passkit API. A REST example can be found on their docs. The example below shows how to get a programs’s info us..
