  • Irving Wladawsky-Berger: New Ways of Understanding Human Behavior

    “It is often said that no person is an island and it takes a village to raise a child, but psychology has largely lacked the scientific evidence to quantify and characterize these aphorisms,” wrote MIT professor Alex (Sandy) Pentland in Contextualizing Human Psychology, - an article published in the August, 2020 issue of Technology, Mind and Behavior, a journal of the American Psychological Association. “As a result, experimental focus is usually on more easily quantifiable individual traits and behaviors.”

    “In the last decade, however, digital data from online interactions, cell phones, and credit cards have allowed us to precisely quantify large-scale social behavior at a very fine level of detail. The little data breadcrumbs that we leave behind as we move around in the world are enabling new ways of understanding human behavior, giving rise to the emerging discipline of computational social science. “[T]hese new tools can help relate individual traits to the surrounding social context and thus better explain life outcomes and societal characteristics.”

    The article illustrated the advances and challenges of data-driven predictions by discussing a 2017 mass collaboration experiment. The experiment asked each of 160 academic teams to predict six life outcomes, - such as a child’s grade point average and whether a family would be evicted from their home, - by analyzing development data of over 4.200 at-risk children from the Fragile Families and Child Wellbeing Study. These data had been collected by interviewing primary caregivers over more than 15 years, as well as other assessments including early childhood education and the children’s scores on a variety of standard tests. Additional information was provided on the parents, including medical, employment, and incarceration histories, religion, and child care practices. Almost 13,000 measurements were made for each child and their family.

  • 10 of our favorite sysadmin stories from 2021 | Enable Sysadmin

    In the Special Theory of Relativity, Albert Einstein popularized the concept that "time is relative" or that "time is a (persistent) illusion."

    In a more prosaic way, we all have the feeling that time appears to move slowly when we are bored and quickly when we are having fun.

  • Becky Stern's machine brings the NYC hot dog experience to you | Arduino Blog

    For her gift to Colin Furze as a participant in this year’s YouTube Makers Secret Santa event, Becky Stern opted to bring the street food of New York City in the form of a mostly automatic hot dog dressing machine. It was designed with the intention of letting a user set down a hot dog at the top of a small roller ramp and then have it slide along as it gets covered in various authentic toppings.

    An Arduino Uno is responsible for controlling all three servo motors via a single PCA9685 driver module and the attached Adafruit Sound Board, which is loaded with sounds that Stern recorded around Manhattan. A separate Adafruit Pro Trinket sits at the base and sends commands to an RGB LED matrix in order to scroll text across the display.

  • 13 Website copiers that help you keep offline mirrored versions of websites

    Ever wanted to save a copy of a certain website to review it later when offline?

    In the early 2000s, we used to copy a whole website into a static HTML format with images and scripts assets, in order to have access to them when disconnected.

    Believe it or not, for many reasons, some are still doing this.

    To have a copy of a website, you need to use a special web crawler, called a website copier that copies all the website into static HTML files alongside its images, styles, and JavaScript files.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
