  • 10 tips for machine learning experiment tracking and reproducibility: Do it yourself approach without additional tooling – IBM Developer

    As machine learning practitioners, we invest significant time and effort to improve our models. You usually do it iteratively and experimentally by repeatedly changing your model, running an experiment, and examining the results, then deciding whether the recent model change was positive and should be kept or discarded.

    Changes in each iteration might involve, for example, changing a value for a hyperparameter, adding a new input feature, changing the underlying machine learning model (for example, by using gradient boosting classification instead of random forest classification), trying a new heuristic, or trying an entirely new approach.

    Experimentation cycles can cause a great deal of confusion. It’s easy to get lost, forgetting what changes you made in the recent experiments and whether the latest results are indeed better than before. A single experiment can take hours or even longer to complete. So, you try to optimize your time and execute multiple experiments simultaneously. This makes it even less manageable, and the confusion gets even worse.

    In this blog, I share lessons and good practices that I learned in my recent machine learning projects. Although I call it a “Do it yourself” approach, some might call it “The caveman way.” I am fully aware that nowadays there are many experiment tracking and management platforms, but it is not always possible or convenient to use them. Some platforms require that you execute your experiments on their platform. Sometimes you can’t share sensitive information outside of your organization, not just the data sets but also results and code. Many platforms require a paid subscription, which can also be a problem in some cases. Sometimes you just want full control of your experiment management approach and data.

    The following practices are easy to implement and do not require additional tooling. They are mostly suitable for small to medium machine learning projects with a single researcher or a small team. Most of the artifacts are saved locally, and adaptations might be required if you want to use a shared storage. As a seasoned developer of production systems, I’m aware that a few of the tips might be considered ‘code-smells’ or bad practices when it comes to traditional development of such systems. However, I believe that they have their place and are justified for short-term research projects. I would like to emphasize that the tips reflect my personal journey and point of view, and not necessarily any official views or practices.

  • Goodbye, CentOS … and welcome back, CentOS 9 Stream - itsfoss.net

    The last couple of years have been messy for the CentOS project and, coinciding with the final stages of this couple of years, there have been announcements that have shaped the new reality of it, whose outcome is fulfilled, following tradition, when we are ending this year. That’s why we say goodbye to CentOS, as we welcome you to CentOS 9 Stream All in a somewhat figurative way, it should be added.

    Recomposing the facts for those who are not up to date, in September 2009 Red Hat announced two releases of its community distribution: CentOS 8, which as always up to that point had been built directly from the source code of Red Hat Enterprise Linux (RHEL); and CentOS Stream, a new variant in format rolling release It was never quite clear how it would fit into the project org chart, given the nature of CentOS, whose pillars have always revolved around stability, long-term support, and a professional solution approach.

  • How we use Linux Test Project to test and improve Linux | Enable Sysadmin

    The Linux Test Project (LTP) is a general-purpose, integrated test suite designed to help organizations using and developing Linux better understand what things work and what still needs work. It is comprised of regression and conformance tests designed to confirm the behavior of the Linux kernel and glibc. Its tools and test suites aim to verify the Linux kernel and related subsystems.

    In short, the Linux Test Project (LTP) is aimed at testing and improving Linux. Its goal is to deliver a suite of automated testing tools for Linux and publish the results of the tests they run. For example, we use LTP tests on Red Hat Enterprise Linux (RHEL) to improve the Linux kernel and system libraries.

  • DevSecOps jobs: 3 ways to get hired | The Enterprisers Project

    In the specialty of DevSecOps, demand for talent has outpaced supply. Many organizations have realized that the traditional siloed development structure is no longer adequate for maintaining application security in light of the ever-increasing pace of software development and delivery. To remedy this problem, many have started shifting security left – having developers run tests and fix security issues in their code.

    As a result, DevSecOps, a function tasked with continuous AppSec testing throughout the DevOps pipeline, has become essential. However, this is a tough field to break into, and figuring out the right path can be challenging. With such a huge demand in the industry for DevSecOps expertise, those who are looking for new opportunities should understand the skills and qualifications needed for this emerging role.

  • 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.
