  • Eclipse Adoptium achieves its first Java SE release

    The Eclipse Adoptium community has achieved its first Java SE release based upon the OpenJDK code. Adoptium is the new home of the AdoptOpenJDK project, the most popular build of OpenJDK in production according to the recent JVM Ecosystem Report, with over 300 million downloads.

    Adoptium’s success builds upon the community development of Java SE in OpenJDK. OpenJDK creates the implementation of Java SE and Adoptium performs the structured build, test, and delivery to end users. Red Hat has brought best in class working practices to these projects to deliver high quality binaries that are ready for production usage.

    Red Hat engineers have a strong representation in the Adoptium project management committee and Red Hat is a strategic member of the Adoptium working group. Together the project management committee and working group provide technical and governance oversight of the project.

    This release from Adoptium is the first from the Eclipse Foundation. As part of the move to Eclipse, Adoptium code underwent enhanced scrutiny through the Eclipse intellectual property review process, and the project’s binaries have passed the Oracle Java SE JCK test suite—- used to determine compatibility with the Java SE specification.

  • The many faces of awk

    The awk command provides a lot more than simply selecting fields from input strings, including pulling out columns of data, printing simple text, evaluating content – even doing math.

  • Week8kdesoc

    helpers module for the printers has been ported to support python2 since no mingw supports python 3 yet, as this just requires removing the variable types in function decarations and returns, however in the case of the actual printers i have decided to create two seperate files for it.

    Although it may be a little time consuming, it makes more sense because there are have become faster in python3 and would be restricting if still using the python2 implemenetation. for example in the case of f"" and %. Some classes to do not work when used with pyhton2 and gdb-mi

  • Dirk Eddelbuettel: RcppFarmHash 0.0.2: Maintenance

    A minor maintenance release of the new package RcppFarmHash, first released in version 0.0.1 a week ago, is now on CRAN in an version 0.0.2.

    RcppFarmHash wraps the Google FarmHash family of hash functions (written by Geoff Pike and contributors) that are used for example by Google BigQuery for the FARM_FINGERPRINT digest.

    This releases adds a #define which was needed on everybody’s favourite CRAN platform to not attempt to include a missing header endian.h. With this added #define all is well as we can already tell from looking at the CRAN status where the three machines maintained by you-may-know-who have already built the package. The others will follow over the next few days.

  • GSoC 2021 KMyMoney - Week 8

    Week 8 revolved around removing all the usages of webpricequote on the equity price update dialog source code. For people not much into finance, an article from Investopedia about quotes.
    I first replaced the WebPriceQuote constructors and their members of AlkOnlineQuoteSource. Replacing m_webIDBy with m_idSelector popped up error. After putting in a little effort I remembered that m_idSelector is the member of AlkOnlineQuoteSource::Private and I will have to use the getter(idSelector()) to use that member for an AlkOnlineQuoteSource object.

  • 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.
