  • David Rheinsberg: Goodbye Gnu-EFI!

    The recommended way to link UEFI applications on linux was until now through GNU-EFI, a toolchain provided by the GNU Project that bridges from the ELF world into COFF/PE32+. But why don’t we compile directly to native UEFI? A short dive into the past of GNU Toolchains, its remnants, and a surprisingly simple way out.

    The Linux World (and many UNIX Derivatives for that matter) is modeled around ELF. With statically linked languages becoming more prevalent, the impact of the ABI diminishes, but it still defines properties far beyond just how to call functions. The ABI your system uses also effects how compiler and linker interact, how binaries export information (especially symbols), and what features application developers can make use of. We have become used to ELF, and require its properties in places we didn’t expect.

  • GNUnet 0.11.0 released

    We are pleased to announce the release of GNUnet 0.11.0.

    This is a major release after about five years of development. In terms of usability, users should be aware that there are still a large number of known open issues in particular with respect to ease of use, but also some critical privacy issues especially for mobile users. Also, the nascent network is tiny (about 200 peers) and thus unlikely to provide good anonymity or extensive amounts of interesting information. As a result, the 0.11.0 release is still only suitable for early adopters with some reasonable pain tolerance.

  • Open source database company MongoDB is giving up on an important battle in its fight against the major cloud computing providers

    After a months-long fight to get a stamp of approval from the Open Source Initiative, MongoDB is withdrawing from the process of having its controversial new software license approved to be called open source.

  • Considering Fresh C Extensions

    Matthew Wilcox recently realized there might be a value in depending on C extensions provided by the Plan 9 variant of the C programming language. All it would require is using the -fplan9-extensions command-line argument when compiling the kernel. As Matthew pointed out, Plan 9 extensions have been supported in GCC as of version 4.6, which is the minimum version supported by the kernel. So theoretically, there would be no conflict.

    Nick Desaulniers felt that any addition of -f compiler flags to any project always would need careful consideration. Depending on what the extensions are needed for, they could be either helpful or downright dangerous.

    In the current case, Matthew wanted to use the Plan 9 extensions to shave precious bytes off of a cyclic memory allocation that needed to store a reference to the "next" value. Using the extensions, Matthew said, he could embed the "next" value without breaking various existing function calls.

    Nick also suggested making any such extension dependencies optional, so that other compilers would continue to be able to compile the kernel.

  • Return the probability of drawing a blue marble

    It seems like I have not decide yet which project am I going to create next so why not just work on another python solution on CodeWars in this chapter. I think I will work on a few more python questions in the next few chapters before starting a brand new python project.

  • GCC 9 will come with improved diagnostics, simpler C++ errors and much more

    The team added a left-hand margin that shows line numbers. GCC9 now has a new look for the diagnostics. The diagnostics can label regions of the source code in order to show relevant information. The diagnostics come with left-hand and right-hand sides of the “+” operator, so GCC highlights them inline. The team has added a JSON output format such that GCC 9 now has a machine-readable output format for diagnostics.

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.
