  • C++ Standard Version Mix-up

    At work we use the LLVM/clang libraries for pre-processing and parsing C/C++ stuff.

    During some experimenting with the current master version of these libraries, I stumbled on unexpected crashes inside our unit-tests on Windows.

    We work with MSVC 2019 on Windows and all worked fine with LLVM 9.x, but with master, close to all my tests did now segfault in aligned_free.

    I first thought that might be some current regression in LLVM master, but after tracing it back to having DenseSet/Map crashing during destruction, this seemed unlikely.

    On further investigation, the fault is really hilarious: We compiled the LLVM libraries with the default language standard as set there in the CMake tooling: C++14.

    On the other side, we compiled our own tools that use these libraries with C++17.

  • Object-Oriented Programming Concepts

    Object-Oriented Programming Concepts, as you know we are going to learn Java programming language, the Java is an object-oriented programing language. Don’t worry about it if you do not understand what it is because I will explain it to you.

  • How UC Berkeley Students Helped Improve CC Search

    Since its launch, CC Search has become more than just a search tool for CC-licensed content; it has come to exemplify the virtuous cycle of knowledge creation—where we create, collaborate, and learn from one another.

    Our recent collaboration with a group of students from UC Berkeley was a true exercise in this cycle of creation and collaboration.

    In the fall of 2019, instructors of the UC Berkeley graduate course, Product Design Studio, approached us to act as “clients” to a group of students learning how to solve complex design challenges. Of course, we said yes! And thanks to prior user research on CC Search, we already knew what design challenges we faced but were struggling with how to fix them—that’s where the students’ insights were critical.

  • Testing your Bash script

    In the first article in this series, you created your first, very small, one-line Bash script and explored the reasons for creating shell scripts. In the second article, you began creating a fairly simple template that can be a starting point for other Bash programs and began testing it.

    [...]

    The Bash shell, like all programming languages, can deal with variables. A variable is a symbolic name that refers to a specific location in memory that contains a value of some sort. The value of a variable is changeable, i.e., it is variable. If you are not familiar with using variables, read my article How to program with Bash: Syntax and tools before you go further.

    Done? Great! Let's now look at some good practices when using variables.

  • 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.
