The purpose of this month's article is to bring once more to the public consciousness some work of Sir Roger Penrose, namely "On the Cohomology of Impossible Figures," which appeared in Structural Topology 17 (1961) pp. 11-16 and was reprinted in Leonardo 25, Nos 3/4 (1992) and then as Chapter 4 of The Visual Mind, Michele Emmer, ed., MIT Press, 1993.
Algorithms are everywhere and some have been around for thousands of years. These 15 are some of the most influential or important ones used in science, math, physics, and computing.
Summary
- Babylonian Algorithms Are the Oldest Ever Found
- Euclid's Algorithm is Still in Use Today
- The 'Sieve of Eratosthenes' is an Ancient, Simple Algorithm
- Boolean (Binary) Algebra Was The Foundation For The Information Age
- Ada Lovelace's Algorithm Was the First Computer Program
- Fast Fourier Transform Breaks Down Signals Into Frequencies
- Google's Ranking Algorithm (PageRank) Could Be the Most Widely Used Algorithm
- Monte Carlo Method (Metropolis Algorithm) Was Used at Los Alamos
- The Simplex Method for Linear Programming was Widely Adopted by Industry
- Krylov Subspace Iteration Methods Are Still Used Today - the deceptively simple task of solving equations of the form Ax = b.
- Kalman Filter is Great For Predicting the Future, sort of
- QR Algorithms For Computing Eigenvalues Have Proved Incredibly Useful
- The Fortran Optimizing Compiler Could Be The Most Important Event in Programming History
- Quicksort Is Great at Helping Sort Things
- JPEG and Other Data Compression Algorithms Are Incredibly Useful
By now, you have likely heard words like "bitcoin" and "blockchain," perhaps even "Ethereum," and wondered what they all mean.
Do they refer to something useful, and if so, how would you go about using it?
This article is intended to put meaning behind these words and others, by highlighting one instance of the technology behind the concepts.
Osquery is an open source Operating System monitoring, query, and analytics software. Created by Facebook, it exposes an operating system as a high-performance relational database that can be queried using SQL-based queries.
Osquery is a multi-platform software, can be installed on Linux, Windows, MacOS, and FreeBSD. Osquery allows us to explore the operating system profile, performance, security and many more metrics by using SQL-based queries.
The alt
is a command line tool that helps you to switch between different versions of commands in Unix-like systems. It is a simple, free, open source tool written in Rust programming language.
(Sequel here: Blockchain is not only crappy technology but a bad vision for the future.)
Industry 4.0 is powered by the fusion of technologies that are connecting the dots between the physical, digital and biological spheres.
Le rivoluzioni del passato hanno permesso di aumentare la ricchezza, ridurre la povertà e migliorare la qualità della vita.
Questa ricerca, presentata nel corso della 43° edizione del Forum “Lo Scenario di oggi e di domani per le strategie competitive”, nasce con l’obiettivo di analizzare lo scenario attuale e gli impatti futuri dell’automazione sul mercato del lavoro italiano, …
Helping to usher in the Industry 4.0 era, NXP Semiconductors announced OpenIL, a Linux distribution meant for smart factory automation.
Ultimate Quality Development System is key to software project Twisted's ability to release stable, reliable code.

The other day I was searching for Vim editor cheatsheets on the web. A quick google search brought me so many links to download the cheatsheets. While going through the links one by one, a...

Good news for penguin users, TrackMania Nations Forever has been released on edge channel as a snap package this information came first on snapcraft.io forum site. Most of Linux users never heard about Track Mania, because it is only available for Windows, Nintendo DS, Wii, PlayStation 4 e Xbox One users.
Howdy Vim users! Today, I have come up with a good news to all of you.
Say hello to Vim-anywhere
, a simple script that allows you to use the Vim editor to input text anywhere in your Linux box. That means you can simply invoke your favorite Vim editor, type whatever you want and paste the text on any application or on a website. The text will be available in your clipboard until you restart your system. This utility is absolutely useful for those who love to use the Vim keybindings often in non-vim environment.
Every now and then, the “why hasn’t decentralized social networking succeeded” discussion pops back up. And inevitably, that motivates somebody who thinks they can do better. They proceed to design a new set of decentralized networking protocols, write lots of code, and get early adopters to enthusiastically adopt the New Thing. Which then, inevitably, never grows beyond a certain size.
Rinse and repeat.
How many times has that now happened? And keeps happening?
Has anybody considered that perhaps the protocols weren’t the problem? Or whether the code was written in one language or another, or did or didn’t use HTML5 or other cool new tech?
Machine learning methods can be used for classification and forecasting on time series problems. Before exploring machine learning methods for time series, it is a good idea to ensure you have exhausted classical linear time series forecasting methods. Classical time series forecasting methods may be focused on linear relationships, nevertheless, they are sophisticated and perform …
