  • An Early Look At The Features Of PostgreSQL 9.6

    PostgreSQL 9.6 isn't being released until later this year, but with it moving along, the release notes are starting to be assembled for this next major update to this open-source SQL server implementation.

    This week added to PostgreSQL Git was the start of the 9.6 release notes. Among the prominent items to mention are the parallel query support, synchronous replication now supports multiple standby servers, full-text search for phrases, support for remote joins/sorts/updates, "substantial" performance improvements (especially for many-core servers), no more repetitive scans of old data by auto vacuum, and much more.

  • Log analytics talk at Apache: Big Data

    As I mentioned earlier, I’ll be talking about feature engineering and outlier detection for infrastructure log data at Apache: Big Data next week. Consider this post a virtual handout for that talk. (I’ll also be presenting another talk on scalable log data analysis later this summer. That talk is also inspired by my recent work with logs but will focus on different parts of the problem, so stay tuned if you’re interested in the domain!)As I mentioned earlier, I’ll be talking about feature engineering and outlier detection for infrastructure log data at Apache: Big Data next week.

  • Hadoop: Can the Tortoise be a Hare?

    As early as 2012, writers, industry critics, and big data companies such as Cloudera predicted Hadoop’s demise as the de facto standard for big data analytics. Hadoop’s future as a viable real-time big data analytics platform seemed questioned at the height of its hype and adoption.

    And indeed, many businesses that manage large data sets have looked elsewhere to find something better to use. In the view of some, Hadoop’s complexity and management requirements make it a technology that cannot survive long-term in business.

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.
