  1. [Old] On SSDs – Lifespans, Health Measurement and RAID

    Solid State Drive (SSD) have made it big and have made their way not only in desktop computing but also in mission-critical servers. SSDs have proved to be a break-through in IO performance and leave HDD far far behind in terms of Random IO performance. Random IO is what most of the database administrators would be concerned about as that is 90% of the IO pattern visible on database servers like MySQL. I have found Intel 520-series and Intel 910-series to be quite popular and they do give very good numbers in terms of Random IOPS. However, its not just performance that you should be concerned about, failure predictions and health gauges are also very important, as loss of data is a big NO-NO. There is a great deal of misconception about the endurance level of SSD, as its mostly compared to rotating disks even when measuring endurance levels, however, there is a big difference in how both SSD and HDD work, and that has a direct impact on the endurance level of SSD.

    I will mostly be taling about MLC SSD, now let’s start off with a SSD primer.

  2. My requirement for DNSSEC: a napkin

    I’m regularly made fun of when teaching DNSSEC because I tell people I use a “napkin” when creating DNSSEC keys to jot down the key tags (or key IDs), and it’s true: also during trainings I have the “napkin” – to be precise it’s a sheet of A4 paper on which I note modifications to schedule, timezones, whether I still owe answers to questions, and of course, the key IDs of DNSSEC keys.

  3. How to install and configure pCloud on Linux Mint | FOSS Linux

    PCloud offers a range of affordable storage plans that are pocket-friendly to anyone. It also provides a compelling size of free cloud storage and gives users complete control over their privacy, something many, if not all, users are looking for.

    Since pCloud is a Swiss-based application, it must adhere to strict Swiss privacy laws, meaning more protection for your files. However, it also puts forward a superb option for most personal and business users, hence an excellent option for all users. This software also interfaces with your browser via pCloud “save,” an extension for Opera, Firefox, and chrome. This extension allows you to directly save images to your particular “pCloud save” folder by only right-clicking on them.

    To add on, this app offers a pCloud web service for users who want to access their files but are away from their PCs. It works exactly like the pCloud app; there are menu links for browsing your files, accessing your public folder, pCloud rewind, backups from other cloud services, and your trash folder.

    Under this are links for accessing your shared folder, download links, crypto folder, and your audio files. To add a file to your web browser interface of pCloud, drag and drop the files into the specific folder by hovering over them, and pCloud will open an upload screen that displays your files uploading to the specified folder.

  5. How to Create Fillable PDF Forms on Linux with ONLYOFFICE

    PDF (Portable Document Format) was invented many years ago by Adobe. It is currently the most popular format for sharing information due to its ease of use, security, reliability, and compatibility with all devices we use on a daily basis.

    This format ensures that a file does not alter its original structure under no circumstances when we open it on, for example, computers, tablets, smartphones, etc. Moreover, PDF makes it possible to add fields that other users can fill out with the required information.

  • 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.
