  • Excellent Free Tutorials to Learn Scratch

    Scratch is a visual programming language developed by the Lifelong Kindergarten Group at the MIT Media Lab. Scratch teaches programming concepts to kids, offering a stepping stone to more complicated programming languages. Coding includes dragging and dropping various code blocks and linking them together like jigsaw pieces to form logical scripts. While the MIT Media Lab designed this language for 8-16 year-old children, it’s used by people of all ages.

    Scratch has received many plaudits as an ideal way to introduce kids to computer programming and computational thinking. It’s a fantastic beginner’s language. Scratch is often used to make games, interactive stories, and animations, but it can be used for any purpose. The language uses event-driven programming with multiple active objects. The language helps students to think creatively, reason logically, and work together. The language is frequently used in schools, libraries, community centers, and museums.

    Scratch is released under an open source license.

  • 'Trust no one' is good enough for the X Files but not for software devs: How do you use third-party libs and stay secure, experts mull on stage

    In a chilly conference room at the San Francisco's Hyatt Regency on Monday, legal and digital security pros convened at USENIX's Enigma conference to hold forth on security, privacy, and related matters.

    Following a discussion panel on encrypted messaging, the talk turned to mitigating the risks that come with using third-party code, external vendors, and crowdsourced advice.

    Those risks became more apparent in the security problems spotted in a series of software libraries over the past few years.

    In August last year, a Ruby software package called rest-client was found to be sending credentials to a remote server. In November, 2018, the NPM module event-stream was modified to steal cryptocurrency. There were similar incidents in July last year involving the NPM module electron-native-notify and in September, 2017, when the PyPI, the repository for Python software packages, was found to be hosting malicious software libraries.

  • Technical Debt is Soul-crushing

    The problem starts when companies forget to pay off the debt and let it accumulate and pile up. For good software developers, it is totally demoralizing to work on products that have high tech debt. This aspect isn’t often talked about but it’s effects are very real. Simple things like changing a title tag of a webpage page takes up a whole day because the logic was scattered in five different files. At the end of the day, it’s not a great feeling that it took so much time for a small task. It’s even more upsetting when they have to explain it to their managers, colleagues or the product team why it took so long. Troubleshooting a bug is not just difficult but also painful. Jeff Atwood called it a major disincentive to work on a project: [...]

  • An update on bradfitz: Leaving Google

    After ~12.5 years at Google and ~10 years working on Go (#golang), it's time for me to do something new. Tomorrow is my last day at Google.

    Working at Google and on Go has been a highlight of my career. Go really made programming fun for me again, and I've had fun helping make it. I want to thank Rob Pike for letting me work on Go full time (instead of just as a distraction on painfully long gBus rides) as well as Russ Cox and Ian Lance Taylor and Robert Griesemer and others for all the patience while I learned my way around. I've loved hacking on various packages and systems with the team and members of the community, giving a bunch of talks, hanging out in Denver, Sydney, MTV, NYC, at FOSDEM and other meet-ups, etc. While I've learned a bunch while working on Go, more excitingly I discovered many things that I didn't know I didn't know, and it was a joy watching the whole team and community work their (to me) magic.

  • 'I am done with open source': Developer of Rust Actix web framework quits, appoints new maintainer

    The maintainer of the Actix web framework, written in Rust, has quit the project after complaining of a toxic web community - although over 100 Actix users have since signed a letter of support for him.

    Actix Web was developed by Nikolay Kim, who is also a senior software engineer at Microsoft, though the Actix project is not an official Microsoft project. Actix Web is based on Actix, a framework for Rust based on the Actor model, also developed by Kim.

    The web framework is important to the Rust community partly because it addresses a common use case (development web applications) and partly because of its outstanding performance. For some tests, Acitx tops the Techempower benchmarks.

    The project is open source and while it is popular, there has been some unhappiness among users about its use of "unsafe" code. In Rust, there is the concept of safe and unsafe. Safe code is protected from common bugs (and more importantly, security vulnerabilities) arising from issues like variables which point to uninitialized memory, or variables which are used after the memory allocated to them has been freed, or attempting to write data to a variable which exceeds the memory allocated. Code in Rust is safe by default, but the language also supports unsafe code, which can be useful for interoperability or to improve performance.

  • 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.
