  • Lesser Known PostgreSQL Features

    Office is not unique in this sense. Most of us are not aware of all the features in tools we use on a daily basis, especially if it's big and extensive like PostgreSQL. With PostgreSQL 14 released just a few weeks ago, what a better opportunity to shed a light on some lesser known features that already exist in PostgreSQL, but you may not know.

  • Perl Weekly: Issue #537 - 2021-11-08 - How do you spend your free time?

    So how do you spend your free time? Do you write more code? Do you try to explain what you wrote, how you wrote and why? Or do you spend your time on some other activities? I, for examples started to read a lot more than I did in the recent years. And sure, I'll even share my recommendations with you. (See below.)

  • Don’t fear losing Elsevier access, California negotiator tells UK

    UK universities should not fear being cut off from Elsevier journals if the stand-off over a new deal with the publisher continues into next year, according to the University of California’s lead negotiator.

    They were well placed to cope with not having access for an extended period, said Jeff MacKie-Mason, who co-chaired California’s task force when it walked away from negotiations with the Dutch publishing giant in 2019, leading to nearly two years without direct access to Elsevier content until an open access deal was struck in March 2021.

    “If UK universities prepare, as we did, they should be able to sustain as long, or longer, a subscription stand-off,” Professor MacKie-Mason told Times Higher Education.

  • Tales of Grace Hopper

    Communications of the ACM, November 2021, Vol. 64 No. 11, Page 7 10.1145/3485446

    My career started when I joined Kodak in the U.K. in 1959, where I was taught to program by Conway Berners-Lee, father of Sir Tim Berners-Lee, the WWW inventor. At that time, we only knew of about 300 stored program computers in the world, although there were probably 300 more in 'secret' places like the military or government.

  • Grace Hopper, Minicomputers, and Megabytes: It's a Fun Career

    After a dinner in 1973, she asked if we would like to see the new computer Univac had loaned her. She dived into her handbag and brought out an object the size of a cigarette packet. We all stared, amazed, as she opened the box and picked up an even smaller object. Grace proceeded to tell us the impossibly small computer had a 64-kilobyte COBOL complier. We wanted to see it in action, so someone brought over a teletype with a printer, and from the side of the device Grace pulled out a fine cable the width of a human hair and a transformer with an adaptor for the fine cable to plug into as the power supply.

    The group watched as Grace ran a simple COBOL program. We didn't know it then, but we had just witnessed an early silicon chip-based computer. In Grace's opinion, the mainframe was dead and would be replaced by 'multitudes of minicomputers' that would be linked by telephone lines, all working together. It was quite possible she had seen a demonstration of the U.S. Department of Defense's ARPANET, the precursor of the Internet.

  • Openpower Summit 2021

    When talking about POWER I’m sometimes accused that I’m beating a dead horse. As you can see from just a small selection of talks at the OpenPOWER Summit 2021, the community around POWER is quite lively. Curriculum, new instructions and various new hardware are under development. If all goes well, POWER will be a lot more accessible to users and developers hopefully already next year!

  • Original Apple Built by Jobs and Wozniak to be Auctioned

    What makes it even rarer is the fact it is encased in koa wood -- a richly patinated wood native to Hawaii. Only a handful of the original 200 were made in this way.

    Apple-1s were mostly sold as component parts by Jobs and Wozniak. One computer shop that took delivery of around 50 units decided to encase some of them in wood, the auction house said

    "This is kind of the holy grail for vintage electronics and computer tech collectors," Apple-1 expert Corey Cohen told the Los Angeles Times. "That really makes it exciting for a lot of people."

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • 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.
