  • I Love LAMP

    Hey all, Ernie here with a piece from the archives on the magical power of a certain concoction of programming and server environment that is everywhere … but perhaps unloved. May you find a spot in your heart to think about how great the LAMP Stack is.

  • Pitting Steam Deck Against Nintendo Switch

    Portable gaming has been around for decades. Despite all the past success, one of the two dominant brands – Sony – has discontinued the PlayStation Vita a couple of years ago, leaving only Nintendo Switch in the market. That said, nothing is smooth sailing for Nintendo as the current most-used portable gaming hardware on the planet is a smartphone, especially the ones with enough processing power to run a high-profile game, it had a serious impact on the portable console market.

    There are around 6 billion active smartphones today – and statistics show that each new smartphone has a game downloaded within a week from its purchase. The variety of games on smartphones is amazing, covering everything from video slots at Spin Online Casino to shooters like Fortnite and others. Of course, hyper-casual games like the slot machines are the most played ones on smartphones – they are perfect to be played on a touchscreen, they are simple, easy to learn, and provide instant gratification.

  • Linux 5.15 Has A Critical Improvement For Tiered Memory Servers - Phoronix

    Landing via Andrew Morton's patch series today in the Linux 5.15 kernel is handling for demoting pages during memory reclaim, which can be used for punting cold pages off to slower, tiered memory devices (like Intel persistent memory) when under system memory pressure.

    The current behavior with Linux right now is when the system memory (RAM) fills up under memory pressure, some of the DRAM contents will be tossed out. For recent and future servers with tiered memory like using Intel Optane DC persistent memory, the Linux kernel may eventually fall over to start using that persistent memory if necessary for allocations but not in any intelligent manner.

  • DTOS Was A Meme. Now I'm Making It A Reality! - Invidious

    For several months, I've talked about potentially making a deployment script or even a full-fledged ISO for my Xmonad/Emacs desktop. The project got put on hold several times, especially during this summer where I didn't have a home computer for three months. But now that I have a home computer again, it's time to actually get this thing started. NOTE: The deployment script and the repo are still in early stages of development.

  • traceroute(8) gets speed boost

    This rewrites the traceroute engine to use libevent and asr's async DNS interface. Probes are now send every 30ms or as soon as we get an answer back. With that we got the 15 minute worse case down to about 10 seconds.

  • Doomscrolling, ads in texting, Theranos NOT Thanos, and more are the tweets on this week’s #TopShelf

    At Mozilla, we believe part of making the internet we want is celebrating the best of the internet, and that can be as simple as sharing a tweet that made us pause in our feed. Twitter isn’t perfect, but there are individual tweets that come pretty close.

  • uBlock Origin—everything you need to know about the ad blocker - Firefox Add-on Reviews

    Rare is the browser extension that can satisfy both passive and power users. But that’s an essential part of uBlock Origin’s brilliance—it is an ad blocker you could recommend to your most tech forward friend as easily as you could to someone who’s just emerged from the jungle lost for the past 20 years.

    If you install uBlock Origin and do nothing else, right out of the box it will block nearly all types of internet advertising—everything from big blinking banners to search ads and video pre-rolls and all the rest. However if you want extremely granular levels of content control, uBlock Origin can accommodate via advanced settings.

    We’ll try to split the middle here and walk through a few of the extension’s most intriguing features and options…

  • gfldex: Calling by name

    While looking for something completely different, I found that Roast really likes named callable placeholder variables.

  • From open Guest Wi-Fi to pwning a lift

    A recent engagement took quite an unexpected turn and led to me having remote control of a bunch of building services including a lift from the street outside, unauthenticated. A single firewall rule bypassed some well configured VLANs and led to an emergency change being made to assure safety, let alone security!

    I was on site and looking at a brand-new network installation in a shared office building. The ground floor offered public spaces including a café, so there was potential for any member of the public to be present.

    Sat with a cuppa, my first port of call was the open Guest Wi-Fi access point. I was presented with a landing page asking me to accept a EULA before being given an IP address and a gateway to access the Internet.

  • 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.
