    • Make Use Of6 Reasons Why Linux Doesn’t Need an Antivirus or Firewall

      Linux isn't invulnerable. In fact, that's one of the most common cybersecurity myths that gets Linux users into trouble. This belief makes it easy to put your guard down, and when your guard is down, you're most likely to get sucker punched.

      But just because Linux has security holes doesn't mean you need antivirus or firewall software. While you may decide to install one anyway—and there's nothing wrong with that—here are a few reasons why it may not be as helpful as you think.

      • Notebook CheckSystem76 upgrades its Lemur Pro Linux-based laptops with Intel Alder Lake-U processors

        CPU options include the Core i5-1235U and Core i7-1255U models that can be coupled with up to 40 GB of DDR4-3200 RAM and up to 4 TB SSD storage via two M.2 slots. Other highlights include a Thunderbolt 4 connector, a 1080p webcam with IR sensor and a microSD card reader.

        System76 is upgrading the Lemur Pro Linux-based laptops with 12th gen Alder Lake-U processors. The base specs include an Intel Core i5-1235U model with 10 cores and 12 threads running at up to 4.4 GHz, but there is also a more powerful option with the Core i7-1255U running at max 4.7 GHz.

        The thin and light chassis (2.54 lbs, 0.65-inch profile) and 14.1-inch 1080p screen appear to be unchanged from the previous version. Thus there is only the Iris Xe iGPU, and System76 offers a maximum of 40 GB of RAM (8 GB soldered + 8 / 16 / 32 options). Maximum storage capacity is 4 TB via 2x M.2 slots, but only one slot is connected to the PCIe 4.0 lanes. Connectivity is ensured through a Wi-Fi 6 + BT 5 module and a 1080p webcam is included.

      • ID RootHow To Install Snap on AlmaLinux 9 - idroot

        In this tutorial, we will show you how to install Snap on AlmaLinux 9. For those of you who didn’t know, Snaps are containerized software packages that are simple to create and install. They auto-update and are safe to run. Snap can be installed and, for the most part, work with most packages on AlmaLinux-based systems that are currently actively supported. Basically, Snaps have their own isolated environment that’s why it doesn’t matter which Linux distro we are using.

        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 Snap on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

HPE has endeavored to position itself as the preeminent private cloud provider, fueled by its GreenLake consumption-driven approach. In order to provide the cloud native experience that so many clients are looking for but delivered within the client datacenter, a crucial technology is Kubernetes.

      • Simon Hørup EskildsenScaling Causal's Spreadsheet Engine from Thousands to Billions of Cells: From Maps to Arrays

        Causal is a spreadsheet built for the 21st century to help people work better with numbers. Behind Causal’s innocent web UI is a complex calculation engine — an interpreter that executes formulas on an in-memory, multidimensional database. The engine sends the result from evaluating expressions like Price * Units to the browser. The engine calculates the result for each dimension such as time, product name, country e.g. what the revenue was for a single product, during February ‘22, in Australia.

        In the early days of Causal, the calculation engine ran in Javascript in the browser, but that only scaled to 10,000s of cells. So we moved the calculation engine out of the browser to a Node.js service, getting us to acceptable performance for low 100,000s of cells. In its latest and current iteration, we moved the calculation engine to Go, getting us to 1,000,000s of cells.

      • Wesley MooreGenerating RSS Feeds From Web Pages With RSS Please

        Sometimes an RSS feed isn’t available on a website. If the site is open source I will often try to open a PR to add or enable one. That’s not always possible though. Other time the page may be one that would naturally think to provide a feed for, but one would still be useful.

        As an example, when we were looking to buy a house I noticed that listings would often go live on agent’s websites several days or more before they were published to the big aggregators. The market was very competitive so I was regularly visiting all the real estate agent websites to run my search, and check for new listings. At the time I used Feedfry to create RSS feeds from the search results. I could then subscribe to them in Feedbin. Paired with the Feedbin Notifier app I received a notification on my phone whenever there was a new listing matching my search criteria from any of the agents.

        Feedfry is free with ads or paid subscription. I paid while house shopping but let that lapse afterwards. I don’t begrudge them funding the service with ads or subscriptions but I figured I could probably put something together and self-host it. At the same time providing a bit more control over how the elements of the page were extracted to generate the feed. RSS Please is the result.

        RSS Please is an open-source command line application implemented in Rust. It has no runtime dependencies and runs on UNIX-like platforms including FreeBSD, Linux, and macOS. Once I resolve this issue it will run on Windows too. The following sections describe how it’s configured and how I’m running it on my server.

        There’s a self-deprecating joke that much of the Internet is written indirectly by StackOverflow, just as we used to say half of it was glued together with Perl and shell scripts cobbled together from woodcut O’Reilly books. It’s likely true.

          It got me to thinking about how this could be best accomplished. The problem with languages like C and Go is that they're very static. If you want something that is more flexible, with pluggable architecture, then you really need a pluggable language, one that supports late binding.
