  • Ubuntu Blog: A look forward to storage in 2022

    More and more data is being created every day. It truly is non-stop. In 2021 alone, it was predicted that enterprise storage vendors would ship almost 150 Exabytes in capacity, and this number is only expected to increase again in 2022!

    We now see 20TB hard drives on the market to help with these needs, but we have to remain vigilant when building storage clusters, as the access speed of these drives hasn’t really changed at all over the last few years. In failure scenarios, where we have to recreate replicas or erasure-coded shards of data, it can take many many hours with drives of such high capacity.

    So the rule of thumb remains the same: a larger number of smaller drives leads to a more predictable system for any amount of capacity. Of course, you do have to remain pragmatic to balance capacity needs with the cost of increasing the number of spindles.

    [...]

    Open source storage solutions such as Ceph can readily help solve for the growth and scaling challenges seen across the industry.

  • Digging into the community's lore with lei

    Email is often seen as a technology with a dim future; it is slow, easily faked, and buried in spam. Kids These Days want nothing to do with it, and email has lost its charm with many others as well. But many development projects are still dependent on it, and even non-developers still cope with large volumes of mail. While development forges show one possible path away from email, they are not the only one. What if new structures could be built on top of email to address some of its worst problems while keeping the good parts that many projects depend on? The "lei" system recently launched by Konstantin Ryabitsev is a hint of how such a future might look.
    One of the initial motivations for creating LWN, back in 1997, was to spare readers from the impossible task of keeping up with the linux-kernel mailing list. After all, that list was receiving an astounding 100 messages every day, and no rational human being would try to read such a thing. Some 24 years later, that situation has changed: linux-kernel now runs over 1,000 messages per day, and there are dozens of other busy, kernel-oriented mailing lists as well. It is easy to miss important messages while trying to follow that kind of traffic — and few developers even try.

    While much of the traffic that appears on any mailing list is quickly forgettable, some of it has lasting value; that means that good archives are needed. For most of the kernel project's history, those archives did not exist. There were indeed archives for most lists, but they were scattered, of mixed reliability, difficult to search, and usually incomplete. It is only a few years ago that Ryabitsev put together lore.kernel.org to serve as a better solution to this problem. By using a search-friendly archiving system (public-inbox), building complete archives from pieces obtained from numerous sources, and archiving most kernel-oriented lists, Ryabitsev was able to create a resource that quickly became indispensable within the community.

    Lei (which stands for "local email interface") comes out of the public-inbox community. It works nicely with lore, to the point that Ryabitsev refers to the whole system as "lore+lei". The idea behind this combination is to create a new way of dealing with email that allows developers to see interesting messages without having to subscribe to an entire list.

    Public-inbox is built on some interesting ideas, including the use of Git to store the archive itself. The real key to its usefulness, though, is the use of Xapian to implement a fast, focused search capability. The "fast" part allows for nearly instantaneous searches within the millions of messages in the email archive; this query, for example, shows immediately that the term "dromedary" has been used exactly 30 times in all of the lists archived on lore.

  • 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.
