  • Hack Another ELF On The Stack | Hackaday

    [dropbear] recently found herself in a pickle. Dumping some data out of an Android app at a specific point for reverse engineering purposes. While it worked great in the simulator, it was painfully slow on hardware via lldb. The solution was to write a patch and apply it to the ELF file.

    Writing the AArch64 assembly to dump the buffer is relatively trivial, but adding it to the existing ELF and repackaging it into a new APK leads to strange errors. The relative offsets into .rodata are now all wrong. For those who don’t routinely interface with the format of ELF files, we have a fantastic resource to take you into the dark depths. But the quick summary version is that sections contain various resources, and you find parts of those resources by relative offsets. The program header describes what type of resources each section contains.

  • Brodie Robertson: I've Finally Made 1,000 Videos: Content Changes Are Coming

    I have no idea how it's happened but I've finally made 1,000 videos and that's kind of crazy, it's only been 3 years but it feels like it's been so much longer and so much less at the same time.

  • The Kubernetes ecosystem hits its inflection point

    With the Cloud Native Computing Foundation’s KubeCon CloudNativeCon Europe 2022 last week in València, Spain, the Kubernetes world came roaring back to life after a lackluster conference in Los Angeles last fall – in spite of a rigorous conference-wide mask mandate.

    The general feeling at the conference was that the Kubernetes ecosystem is reaching an inflection point. Work on the core Kubernetes platform itself is slowing, as it has reached a level of maturity – while rapid innovation continues unabated across the broader Kubernetes landscape.

    [...]

    The shift is subtle, but noticeable: There is less of a concern for the software infrastructure and a greater focus on the applications that run on that infrastructure – deploying, managing and securing them.

    Kubernetes may not quite be part of the background noise of information technology the way Linux and TCP/IP before it have become, but it’s well on its way. There remain a few missing pieces, and other projects are still rough around the edges, but Kubernetes – and cloud-native computing in general – are here to stay.

  • Linux Weekly Roundup #183

    Welcome to this week's Linux weekly Roundup.

    We had a relatively lovely week in the world of Linux releases, with Kali Linux 2022.2, Peppermint OS 5-22-22 and openSUSE 15.4-rc.

    Inkscape 1.2 has also been released this week.

  • Sergio Talens-Oliag: New Blog

    Welcome to my new Blog for Technical Stuff.

    For a long time I was planning to start publishing technical articles again but to do it I wanted to replace my old blog based on ikiwiki by something more modern.

    I’ve used Jekyll with GitLab Pages to build the Intranet of the ITI and to generate internal documentation sites on Agile Content, but, as happened with ikiwiki, I felt that things were kind of slow and not as easy to maintain as I would like.

    So on Kyso (the Company I work for right now) I switched to Hugo as the Static Site Generator (I still use GitLab Pages to automate the deployment, though), but the contents are written using the Markdown format, while my personal preference is the Asciidoc format.

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.
