  • Supercomputing under a new lens: A Sandia-developed benchmark re-ranks top computers

    A Sandia National Laboratories software program now installed as an additional test for the widely observed TOP500 supercomputer challenge has become increasingly prominent. The program’s full name — High Performance Conjugate Gradients, or HPCG — doesn’t come trippingly to the tongue, but word is seeping out that this relatively new benchmarking program is becoming as valuable as its venerable partner — the High Performance LINPACK program — which some say has become less than satisfactory in measuring many of today’s computational challenges.

  • Bright Computing adds support for OpenHPC

    Today Bright Computing announced it has joined the Linux Foundation and will participate in the OpenHPC Community project. The latest release of Bright Cluster Manager provides the ability for Bright customers to easily integrate OpenHPC libraries and packages for use within a Bright cluster.

  • Usenet, Authentication, and Engineering (or: Early Design Decisions for Usenet)

    A Twitter thread on trolls brought up mention of trolls on Usenet. The reason they were so hard to deal with, even then, has some lessons for today; besides, the history is interesting. (Aside: this is, I think, the first longish thing I've ever written about any of the early design decisions for Usenet. I should note that this is entirely my writing, and memory can play many tricks across nearly 40 years.)

  • The true costs of hosting in the cloud

    Should we host in the cloud or on our own servers? This question was at the center of Dmytro Dyachuk's talk, given during KubeCon + CloudNativeCon last November. While many services simply launch in the cloud without the organizations behind them considering other options, large content-hosting services have actually moved back to their own data centers: Dropbox migrated in 2016 and Instagram in 2014. Because such transitions can be expensive and risky, understanding the economics of hosting is a critical part of launching a new service. Actual hosting costs are often misunderstood, or secret, so it is sometimes difficult to get the numbers right. In this article, we'll use Dyachuk's talk to try to answer the "million dollar question": "buy or rent?"

  • Memcached DDoS Attacks Slow Down as Patching Ramps Up

    Days after the largest distributed denial-of-service attack in internet history, the attack size of memcached DDoS attacks is now on the decline.

    On March 5, Netscout Arbor Networks reported a 1.7-Tbps DDoS attack that was driven by the amplification of misconfigured memcached servers. While there were some initial fears that the attacks would continue to grow in size, the opposite has happened.

    "We're still seeing lots of them, but their average size is considerably smaller due to ongoing cleanup and mitigation efforts," Steinthor Bjarnason, senior network security analyst at Netscout Arbor, told eWEEK.

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.
