  • The future of COBOL is now | InfoWorld

    Early in the 2020 coronavirus pandemic, the New Jersey state government had a very specific IT staffing need—and it got a lot more publicity than hiring moves usually get. The recently passed CARES Act had added $600 to weekly unemployment payments nationwide, but New Jersey’s archaic unemployment software, written in COBOL, couldn’t incorporate the extra money without reprogramming, and there was nobody on staff capable of doing the job.

    The incident was a very public glimpse at a dirty little secret within IT: There are billions of lines of code written in COBOL still running mission critical applications, but the great wave of COBOL-trained programmers who wrote all that code are aging out of the workforce. That story isn’t new—we wrote about it eight years ago, and eleven years before that.

  • inline 0.3.17: Refactored and New Tests

    A new release of the inline package arrived on CRAN this evening and has already been shipped to Debian as well. inline facilitates writing code in-line in simple string expressions or short files. The package was used quite extensively by Rcpp in the days before Rcpp Attributes arrived on the scene proving an even better alternative for its use cases. inline is still use by rstan and a number of other packages.

  • Committed to the integrity of your root filesystem « Colin Walters

    Quite a while ago I came across the SQLite testing page and was impressed (and since then it’s gotten even better). They’ve clearly invested a lot in it, and I think SQLite’s ubiquity is well deserved.

    When I started the ostree project I had this in mind but…testing is hard. We have decent "unit test style" coverage since the start but that’s not very "real world". We’ve gone through a few test frameworks over the years. But to the point of this blog post: I finally had a chance to write some new testing code and I’m happy with how it turned out!

  • Developer Strangelove or How I Learned to Stop Worrying and Love the Waterfall Model - SUSE Communities

    Everyone loves to hate the Waterfall Model (WM) and extoll the virtues of modern development methodologies. But while people are rolling their eyes at the mere mention of the WM, they forget that it was one of the first attempts at a systematic approach to complex system development. Few first attempts turn out to be the best, but all first attempts teach us something. As such, the WM contains pearls of wisdom that should not be ignored.

  • Mohammad S Anwar's Monthly Report - November

    With so much going on in my personal life, it is hard to focus on anything. One thing that I really miss these days are personal time. I am constantly working on it with the help of experts in the field. I try to look at the positive side of the life but I can't ignore the fact I am not giving 100% to my pet project The Weekly Challenge. Having said that I must thank the entire team for the support and encouragement in this difficult time. As of today, we entered into the 89th week. I can't wait to see when we get to the 100th week.

    Ever since I shared about my treatment, I have had many encouraging and supporting messages from friends. I read them again and again. I feel blessed to have such caring friends around me. I have let myself down by not taking part in Hacktoberfest 2020 in the same spirit as before. Atleast I completed the challenge by submitting the required number of Pull Requests.

    Let me share some happy news as well, I have now become co-editor of Perl Weekly Newsletter with the most editions, going past greats like Yanick Champoux and Neil Bowers.

  • 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.
