Programming/Development Leftovers

  • 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.

  • PHP 7.2 is dead - Remi's RPM repository - Blog

    After PHP 7.1, and as announced, PHP version 7.2.34 was the last official release of PHP 7.2 To keep a secure installation, the upgrade to a maintained version is strongly recommended: PHP 7.4 is in active support mode, and will be maintained until November 2021 (2022 for security). PHP 8.0 is in active support mode, and will be maintained until November 2022 (2023 for security).

  • 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.

Games: Pixross, Domains of Dusk, Factory Magnate

  • Picture logic puzzle game Pixross from Kenney is out now and it's total joy | GamingOnLinux

    Kenney, creator of masses of free and paid assets for game developers has released a second game with Pixross. It's a picture logic puzzle game with tons of levels and it's great. Note: key provided by itch.io press access. Seems like Kenney is on a bit of a roll now, after releasing their first commercial title with Frick, Inc. back in October. Across 150+ unique puzzles Pixross has you attempt to find the picture hidden inside, using logic to count the squares that need colouring in on the board.

  • Domains of Dusk is an upcoming urban-mystical grand-strategy RPG | GamingOnLinux

    An urban-mystical grand-strategy RPG? Domains of Dusk certainly has an interesting description from Critique Gaming and it looks very interesting. This is the third game from Critique Gaming following on from the very good Interrogation: You will be deceived in 2019 and Brain Please Don't earlier this year. Seems like they're being a lot more ambitious this time too.

  • Factory Magnate is a new upcoming factory-building tycoon sim | GamingOnLinux

    Game developer Rising Tail have confirmed they're working on Factory Magnate, their own take on the factory building and mining strategy sim with a tycoon style to it. Factory Magnate will take elements from the likes of Factorio and Mindustry for the building and mining side but with different goals. With a "small loan of a million credits" your goal is to build up an empire of factories spread across a procedurally generated solar system. You will be in charge of extracting materials, setting up productions lines and making various products to get them transported off-world to sell.

openSUSE Release Team to Share Results from arm Survey in Online Meetup

Members of the openSUSE release team members will share results of openSUSE on arm during two separate online sessions on openSUSE’s Jisti instance Dec. 2. The first session will be at 10:00 UTC and the second session at 16:00 UTC. Both sessions are expected to cover the same content and reach different time zones globally for those interested in attending. Overall, there were almost 300 responses submitted. The core team to develop the survey wants to use the results as a baseline for future surveys about arm to help gauge trends about development efforts with openSUSE on arm architecture. The results did offer some telling answers about the majority of openSuse use on arm. More than 4 out of 5 responses indicated they used AArch64, Raspberry Pi 3, Raspberry Pi 4, PinePhone and/or Pine64. Read more Also: Candidate slate for the openSUSE Board Election 2020

Precursor’s Custom PCBs

While the last few updates about Precursor have focused on evidence-based trust and security, this update is more about the process of making Precursor itself. There is an essential link between evidence-based trust and understanding the manufacturing process: to convince yourself that something has been constructed correctly, it’s helpful to understand the construction process itself. It’s hard to tell if a small crack in a wall is the result of harmless foundation settling, or a harbinger of a building’s imminent collapse, without first understanding the function and construction of that wall. Most designers like to abstract the PCB away as a commodity service, preferring “no-touch” or “one-click” ordering services where design files are uploaded and finished boards arrive in the mail, on time and at a good price. This is a bit like running a restaurant and ordering your produce from a mass distributor. The quality is uniform, delivery times are good, and the taste is acceptable. However, it’s hard to make a dish that’s really differentiated when basic ingredients all come from the same place. I personally enjoy building electronics with a bit more of an artisanal flavor. Just as gourmet chefs invest the effort to develop relationships with their farmers, I’ve developed a personal relationship with my preferred PCB shop, King Credie. Since a PCB is at the core of virtually everything I build, I have found developing a healthy personal relationship with my PCB supplier has the benefit of raising the bar on virtually all my products. While King Credie is neither the cheapest nor the quickest-turn of PCB shops, their quality is consistent and, most importantly, they are willing to customize their process. For a small shop, they offer a wide variety of speciality processes, such as rigi-flex, metal core, edge plated cavities, HDI, and custom soldermask colors. Read more
