  • GCC's New Static Analysis Capabilities Are Getting Into Shape For GCC 10

    One of many new features in the GCC 10 code compiler releasing in about one month's time is finally having a built-in static analyzer. This static analyzer can be enabled with the -fanalyzer switch and has been maturing nicely for its initial capabilities in the GNU Compiler Collection 10.

    The static analyzer was added to GCC 10 just back in January with an initial focus on C code. This static analyzer for GCC was spearheaded by GCC's David Malcolm and was available in patch form a few months prior. This static analyzer isn't as mature or robust as what's been built into the likes of LLVM Clang for a while now, but it's getting there.

  • It’s just a matter of selecting the right search terms

    Once more, I wanted to push a small change to a Git repository to which the owner gave me write access. This repo is currently the only one for me, for which I need to use https as transport protocol and therefore have to enter username and password for each and every push.

    On the other hand, I keep all my valuable credentials in Pass: The Standard Unix Password Manager for a couple of years now. It stores them with strong GPG encryption on my disk, is nicely integrated into Firefox by a plugin and there is also a KDE plasma widget available, created by my fellow KDE developer Daniel Vrátil. So why can’t Git read (I was about to use pull here, but that might be confusing in the context of Git) the credentials from my password store? There must be a way!

    Next, I started reading the documentation about git-credentials which seems to provide all that is needed. Just that pass was not on the list of helpers. Reading the specs, I expected it to be pretty easy to write a small wrapper that solves the issue. But: this sounds like a problem too obvious and to be solved already. So the search began.

    Using all kinds of combinations of git-credentials, pass, password-store and some more I don’t remember, I always ended up on some general Git documentation, but no sign of what I was looking for. So maybe, it really does not exist (oh, I have not consulted the yellow pages) and I have to develop and provide it to the internet community myself.

  • 6 tricks for developing a work from home schedule

    When you start working from home, one of the first things you might have noticed is that there almost no outside influences on your schedule.

    You probably have meetings—some over team chat and others over video— that you have to attend, but otherwise, there's nothing requiring you to do anything at any specific time. What you find out pretty quickly, though, is that there's an invisible influence that sneaks up on you: deadlines.

    This lack of structure fosters procrastination, sometimes willful and other times aimless, followed by frantic sprints to get something done. Learning to mitigate that, along with all the distractions working from home might offer, is often the hardest part of your home-based work.

    Here are a few ways to build in that structure for yourself do you don't end up feeling like you are falling behind.

  • 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.
