  • 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.

Getting Started with Raspberry Pi Pico using MicroPython and C

Raspberry Pi Pico board was just launched last Thursday, but thanks to Cytron I received a sample a few hours after the announcement, and I’ve now had time to play with the board using MicroPython and C programming language. I went to the official documentation to get started, but I had to look around to achieve what I wanted to do, namely blinking some LEDs, so I’ll document my experience with my own getting started guide for Raspberry Pi Pico using a computer running Ubuntu 20.04 operating system. The instructions will be similar for Windows and Mac OS. Read more

Tiny Core Linux Installation and Review

The OS architectures supported by Tiny Core Linux are x86. X86_64, and ARM processors. It may not be a complete package for a functional Linux distro or flavor, but the freedom and flexibility it offers is out of the box. Under Tiny Core Linux, you get to push your OS around rather than your OS pushing you around like in other platforms. The speed and simplicity under this Linux distro cannot be substituted. Moreover, the absence of a Desktop environment distractions under its user experience is another plus. It gifts you the perfect tinkering experience due to its lightweight nature. Read more
