GNU Mes 0.17 released

Submitted by Roy Schestowitz on Friday 17th of January 2020 12:50:09 AM Filed under
GNU

We are delighted to announce the release of GNU Mes 0.17, representing
64 commits over 6 weeks.

Mes is now an official GNU package and we have bootstrapped gcc-4.7.4
for x86-linux with a reduced binary seed (i.e., without regular toolchain).

Next targets:

 - upstream the x86 Mes bootstrap to GuixSD
 - create a x86_64 Mes C Lib, see if that is is enough to bootstrap x86_64
 - reduce the 1MB ASCII M1 seed to ~5000 LOC/~100KB of M2 source
 - create a plan for Geesh and Gash and use them to reduce the
   bootstrap binary dependencies
 - and/or otherwise reduce the bootstrap binary dependencies

Packages are available from Guix's wip-bootstrap branch.

* About

GNU Mes[0] aims to help create full source bootstrapping for GNU/Linux
distributions such as GuixSD[1] as part of the bootstrappable builds[2]
effort.

It consists of a mutual self-hosting Scheme interpreter written in
~5,000 LOC of simple C and a Nyacc-based C compiler written in Scheme.
This mes.c is being simplified[3] to be transpiled by M2-Planet[4].

The Scheme interpreter (mes.c) has a Garbage Collector, a library of
loadable Scheme modules-- notably Dominique Boucher's LALR[5],
Pre-R6RS portable syntax-case[6] with R7RS ellipsis, Matt Wette's
Nyacc[7] --and test suite just barely enough to support a simple REPL
and simple C-compiler: MesCC.

Mes+MesCC can compile an only lightly patched TinyCC[8] that is
self-hosting.  Using this tcc and the Mes C library we now have a
reduced-binary-seed bootstrap for the gnutools triplet: glibc-2.2.5,
binutils-2.20.1, gcc-4.7.4.

Mes is inspired by The Maxwell Equations of Software: LISP-1.5[9] --
John McCarthy page 13, GNU Guix's source/binary packaging transparency
and Jeremiah Orians's stage0[10] ~500 byte self-hosting hex assembler.

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.
