Introduction One of the headline changes of the C++20 standard is the inclusion of modules. Modules promise to significantly change the structure of C++ codebases and possibly signal headers’ ultimate demise (but probably not in my lifetime). It also opens the door to potentially have a unified build system and…
Comparing astrological drawings from our Digital Collections to NASA images—how similar do you think they are?
Take a rip-roarin' tour through hundreds of PRs worth of performance improvements for .NET 6.
On average, people in larger cities are better off economically. But a new study published in the Royal Society Interface builds on previous research that says, that’s not necessarily true for the individual city-dweller. It turns out, bigger cities also produce more income inequality.
One of the most important optimisation goals underlying the Wendelstein 7-X fusion device at Max Planck Institute for Plasma Physics in Greifswald has now been confirmed. An analysis by IPP scientists in the journal Nature shows: In the optimised magnetic field cage, the energy losses of the plasma are reduced in the…
By training Atlas to maneuver its way through complex parkour courses, our engineers push the humanoid robot to its limits.
This post is co-authored with a team of researchers who have chosen to remain anonymous. They uncovered most of the evidence reported in this post. These researchers are not connected in any way to…

There was a marked acceleration in deforestation in the 20th century. But, global deforestation peaked in the 1980s. Since then, it has slowed.
`atan2f` is an important but slow trigonometric function. In this article we'll explain how to approximate it, and implement a version 50x faster than `glibc` on batches of inputs.
Brute force, gaussian blur, and Jump Flood Algorithm based outline approaches tested and compared.
In June, I was able to officially register Mastodon gGmbH after nearly 8 months of legal work (“gGmbH” means “non-profit limited liability company”). A non-profit limited liability company in Germany is structered and operates similarly to a for-profit limited liability company with a few key differences. The founding…
Deep underneath South Kensington tube station, a huge project is underway to replace all five of the station's escalators, and all of them at the same time.
Recently, I’ve come across a not so efficient implementation of a isEven function (from r/programminghorror ).
The open source Git project just released Git 2.33, with features and bug fixes from over 74 contributors. Here's a look at some of the most interesting features and changes.
A lot of smart college students end up with the idea that “solving hard technical problems” is the best thing they can do with their life—probably because that’s the only thing they’ve ever been rewarded for so far.
Note: These pages make extensive use of the latest XHTML and CSS Standards . They ought to look great in any standards-compliant modern browser. Unfortunately, they will probably look horrible in older browsers, like Netscape 4.x and IE 4.x. Moreover, many posts use MathML, which is, currently only supported in…
The many threats facing bumblebees can be tested using a “virtual safe space” created by scientists at the University of Exeter.
Once I finished writing ec2-boot-bench, the natural next step was to run some tests — in particular, to see how FreeBSD compared to other operating systems used in EC2. I used the c5.xlarge instance type and tested FreeBSD releases since 11.1-RELEASE (the first FreeBSD release which can run on the c5.xlarge instance…
About two months ago, I decided to start developing a fresh codebase for my voxel project – something that many indie developers are probably all-too familiar with, including myself. This time around, there were three major features that I wanted to implement:
To: Oversight Board Good day, My name is Igor Petrov, I am an independent historian. The list of my publications, including those for Cambridge University Press, is available at https://independent.academia.edu/IgorPetrov40 On August 6, 2021, whilst conducting archival research and working with…
Tokenizing the source code input is a great start for our compiler. Now let's turn our attention to parsing the PL/0 grammar. Once we have finished with the parser, the front end of our compiler will be finished and we will have a PL/0 validator. This is a program that can read in PL/0 source code and inform the user…
