  • Local web development vs Vagrant vs Docker: What’s right for you?

    What tools do you use to build your web applications? Your choice matters a lot because you’ll spend a lot of time working in that environment.

    If you make a poor choice, you’ll be stuck with something suboptimal that can slow you down massively and make your project grind to a halt.

    If you make a harmonious choice, your tool will aide you on your development journey and let you crank out features to delight your customers.

  • Hacking math education with Python

    Mathematics instruction has a bad reputation, especially with people (like me) who've had trouble with the traditional approach, which emphasizes rote memorization and theory that seems far removed from students' real world.

    While teaching a student who was baffled by his math lessons, Peter Farrell, a Python developer and mathematics teacher, decided to try using Python to teach the boy the math concepts he was having trouble learning.

    Peter was inspired by the work of Seymour Papert, the father of the Logo programming language, which lives on in Python's Turtle module. The Turtle metaphor hooked Peter on Python and using it to teach math, much like I was drawn to Python.

  • BH 1.69.0-1 on CRAN

    The BH package provides a sizeable portion of the Boost C++ libraries as a set of template headers for use by R. It is quite popular, and frequently used together with Rcpp. The BH CRAN page shows e.g. that it is used by rstan, dplyr as well as a few other packages. The current count of reverse dependencies is at 164.

    Boost releases every four months. The last release we packaged was 1.66 from February—and this BH release gets us to Boost 1.69 released just three or so weeks ago. And as blogged last month, we made a pre-release (following several reverse-depends checks) to allow three packages affected by changes in Boost to adapt. My RcppStreams package was one, and we made an update release 0.1.2 just yesterday. This BH release was also preceded by another reverse-depends check on the weekend.

    Sine the 1.66 release of BH, CRAN tightened policies some more. Pragmas suppressing compiler warnings are now verboten so I had to disable a few. Expect compilations of packages using Boost, and BH, to be potentially very noisy. Consider adding flags to your local ~/.R/Makeconf and we should add them to the src/Makevars as much as we can (eg my ticket #3961 to dplyr). Collecting a few of these on a BH wiki page may not be a bad idea.

  • Rust in 2019: Focus on sustainability

    To me, 2018 felt like a big turning point for Rust, and it wasn’t just the edition. Suddenly, it has become “normal” for me to meet people using Rust at their jobs. Rust conferences are growing and starting to have large number of sponsors. Heck, I even met some professional Rust developers amongst the parents at a kid’s birthday party recently. Something has shifted, and I like it.

    At the same time, I’ve also noticed a lot of exhaustion. I know I feel it – and a lot of people I talk to seem to feel the same way. It’s great that so much is going on in the Rust world, but we need to get better at scaling our processes up and processing it effectively.

    When I think about a “theme” for 2019, the word that keeps coming to mind for me is sustainability. I think Rust has been moving at a breakneck pace since 1.0, and that’s been great: it’s what Rust needed. But as Rust gains more solid footing out there, it’s a good idea for us to start looking for how we can go back and tend to the structures we’ve built.

  • 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.
