  • Fujitsu Begins Adding A64FX Support To GCC Compiler

    The Fujitsu A64FX ARM processor that has 48 cores per node and 32GB of HBM2 memory that currently powers the fastest supercomputer is beginning to see GCC compiler support.

    Fujitsu months ago upstreamed A64FX support to the LLVM/Clang compiler. It appears this ARMv8.2-based chip with 512-bit SIMD is using LLVM/Clang as its preferred compiler. But now Fujitsu is also upstreaming GCC support for their high performance A64FX.

  • Junichi Uekawa: Started writing some golang code.

    Started writing some golang code. Trying to rewrite some of the tools as a daily driver for machine management tool. It's easier than rust in that having a good rust compiler is a hassle though golang preinstalled on systems can build and run. go run is simple enough to invoke on most Debian systems.

  • Url Shortner in Golang

    I decided to write my own URL shortner and the reason for doing that was to dive a little more into golang and to learn more about systems. I have planned to not only document my learning but also find and point our different ways in which this application can be made scalable, resilient and robust.

  • LLVM Clang 11 Has A Nice Build Speed Improvement With New Feature For Pre-Compiled Headers

    There are many improvements in LLVM/Clang 11.0 due out in the weeks ahead though an interesting change merged prior to last month's code branching that slipped under our radar... If using the clang-cl driver for MSVC or when otherwise making use of pre-compiled headers (PCH) functionality, there is a new option that can offer significant build time speed-ups.

    When making use of Clang PCH functionality for leveraging pre-compiled headers, Clang 11.0 is introducing the -fpch-instantiate-templates option separate from the existing PCH options. This -fpch-instantiate-templates option instantiates templates already while generating a precompiled header instead of instantiating every time the pre-compiled header is used. Avoiding the instantiation each time the pre-compiled header is used can provide measurable build time improvements. Aside from the MSVC clang-cl drop-in, this feature though isn't enabled by default since it can result in errors if the source header file is not self-contained.

  • PSF GSoC students blogs: Week 6 Check-in

    Works towards analyzing multistage dockerfile. I combined the draft PR and the review from my mentors, the new commit is the first step of my plan. We split the multistage dockerfile into seperate dockefiles for build. Here are the changes in the new commit.

    1. Modified function check_multistage_dockerfile() to return.

    2. Remove function split_multistage_dockerfile() since we are working on the building stage. split_multistage_dockerfile() can be improved on analyze stage.

  • Generate a random number in Java

    Java contains many ways to generate random numbers. The random number can be int, long, float, double, and Boolean. Math.random class and Random class are mostly used to generate random numbers in Java. The uses of these classes are shown in this tutorial by using various examples.

    [...]

    The random class has many methods to generate different types of random numbers, such as nextInt(), nextDouble(), nextLong, etc. So, the integer and fractional numbers can be generated by using the appropriate method of this class. You have to create an object to use in this class.

  • 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.
