  • The Linux Foundation's "security mobilization plan" [Ed: Making up numbers for a FUD campaign led by proprietary software companies that make back doors for the NSA]

    The Linux Foundation has posted an "Open Source Software Security Mobilization Plan" that aims to address a number of perceived security problems with the expenditure of nearly $140 million over two years.

  • Our build and release infrastructure, and upcoming updates | F-Droid - Free and Open Source Android App Repository

    Behind the scenes of F-Droid is a giant pile of automation to manage the process of building thousands of apps from source. This means checking out thousands of source repos, checking them all for updates, building and new releases, and securely signing them en masse. All builds are run in a fresh virtual machine guest instance known as the buildserver. All Gradle binaries and Android SDK packages are verified against our public logs of observed SHA-256 checksums. The transparency log processes also verify against upstream’s public checksums.

    Our setup runs on Debian almost exclusively. Debian is a leader in free software, rock solid servers, and reproducible builds. That makes it a natural home for F-Droid. We also work to ensure we maintain the packages we use, and build our processes on top of Debian packages. That means we share the maintenance with anything that uses Debian. It may seem like more work to give back, but our experience is that it pays off in the long run. The F-Droid community is able to maintain many things with a small team. Another example of this is this website itself: it is built using Jekyll packages that are all in Debian.

  • F-Droid: Our build and release infrastructure, and upcoming updates

    Here's an update from F-Droid regarding upcoming changes to its build and distribution infrastructure.

  • Tails 5.0 Linux users warned against using it "for sensitive information" [Ed: Microsoft-connected site shedding doubt on "Linux"]

    Tails developers have warned users to stop using the portable Debian-based Linux distro until the next release if they're entering or accessing sensitive information using the bundled Tor Browser application.

  • CISA Adds 34 Known Exploited Vulnerabilities to Catalog [Ed: Lots and lots of Microsoft. Actively exploited.]

    CISA has added 34 new vulnerabilities to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation. These types of vulnerabilities are a frequent attack vector for malicious cyber actors and pose significant risk to the federal enterprise. Note: to view the newly added vulnerabilities in the catalog, click on the arrow on the of the "Date Added to Catalog" column, which will sort by descending dates.

  • Google Releases Security Updates for Chrome

    Google has released Chrome version 102.0.5005.61 for Windows, Mac, and Linux. This version addresses vulnerabilities that an attacker could exploit to take control of an affected system.

  • Stable Channel Update for Desktop
  • Google has been DDoSing SourceHut for over a year

    Just now, I took a look at the HTTP logs on git.sr.ht. Of the past 100,000 HTTP requests received by git.sr.ht (representing about 2½ hours of logs), 4,774 have been requested by GoModuleProxy — 5% of all traffic. And their requests are not cheap: every one is a complete git clone. They come in bursts, so every few minutes we get a big spike from Go, along with a constant murmur of Go traffic.

    This has been ongoing since around the release of Go 1.16, which came with some changes to how Go uses modules. Since this release, following a gradual ramp-up in traffic as the release was rolled out to users, git.sr.ht has had a constant floor of I/O and network load for which the majority can be attributed to Go.

    I started to suspect that something strange was going on when our I/O alarms started going off in February 2021 (we eventually had to tune these alarms up above the floor of I/O noise generated by Go), correlated with lots of activity from a Go user agent. I was able to narrow it down with some effort, but to the credit of the Go team they did change their User-Agent to make more apparent what was going on. Ultimately, this proved to be the end of the Go team’s helpfulness in this matter.

  • New ‘Cheers’ Linux ransomware targets VMware ESXi servers [Ed: Well, ransomware is mostly a Windows issue and VMware is proprietary software, but then again, this is a Microsoft-connected site looking to alter or distort perceptions]

    A new ransomware named ‘Cheers’ has appeared in the cybercrime space and has started its operations by targeting vulnerable VMware ESXi servers.

    VMware ESXi is a virtualization platform commonly used by large organizations worldwide, so encrypting them typically causes severe disruption to a business’ operations.

  • 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.
