  • Top 10 Reasons Why Desktop Linux Failed

    1) Linux isn't pre-installed - No matter how much we may debate it, having Windows pre-installed on PCs means that's what people are likely to end up using. In order for someone to move over to Linux on the desktop, there must be a clear reason to do so. There is the problem. The only time I've personally seen users make the switch over to Linux from Windows comes down to frustration with Windows or a desire to advance their skills into an IT field.

    My own Linux story, for example, was a mixture of the two examples above. First off, I was just done with Windows. I had already been dabbling with Linux at the time I completely switched, but I become disenfranchised with the Microsoft way of doing things. So for me, the switch to Linux was based out of frustration.

    Had I not experienced any frustrations with Windows, I might not have ever thought to jump ship over to an alternative. Even when I built my own PCs myself, the OS offered at computer stores was Windows only. This is a huge hurdle for Linux adoption on the desktop.

    2) Linux freedom vs convenience - It's been my experience that people expect a user experience that's consistent and convenience. How one defines this depends on the individual user. For some, it's a matter of familiarity or perceived dependability. For more advanced PC users, a consistent convenience may mean a preferred workflow or specific applications.

    The greater takeaway is that when people are aware of other operating systems, they will usually stick with that they've used the longest. This presents a problem when getting people to try Linux. When using a desktop platform for a long time, you develop habits and expectations that don't lend themselves well to change.

  • Optimizing a Python application with C++ code

    I’ve been working lately in a command line application called Bard which is a music manager for your local music collection. Bard does an acoustic fingerprinting of your songs (using acoustid) and stores all song metadata in a sqlite database. With this, you can do queries and find song duplicates easily even if the songs are not correctly tagged. I’ll talk in another post more about Bard and its features, but here I wanted to talk about the algorithm to find song duplicates and how I optimized it to run around 8000 times faster.

    [...]

    An obvious improvement I didn’t do yet was replacing the map with a vector so I don’t have to convert it before each for_each call. Also, vectors allow to reserve space in advance, and since I know the final size the vector will have at the end of the whole algorithm, I changed to code to use reserve wisely.

    This commit gave the last increase of speed, to 7998x, 36680 songs/second and would fully process a music collection of 1000 songs in just 13 seconds..

  • How A KDE Developer Used C++17 & Boost.Python For About A 8,000x Speed-Up

    Open-source developer Antonio Larrosa who contributes to KDE and openSUSE has been developing a command-line music manager called Bard. He's written an interesting post about how he sped up some of his operations by around eight-thousand times faster.

    In particular, Antonio was focused on speeding up the process of finding song/music duplicates in the user's local music collection. What started out as Python code was morphed into optimized C++ code. Little surprise, the C++ code once tuned was immensely faster than Python -- but the blog post is interesting for those curious about the impact of the various steps he took for tuning this implementation.

  • GLib 2.58 Is Looking Good With Portability Improvements, Efficient Process Launching

    The GLib low-level GNOME library while being quite mature is seeing a significant update with its version 2.58 release due out this September for GNOME 3.30.

    Two of the biggest GLib 2.58 changes we have covered up to now on Phoronix has been the new generic reference counting API and more efficient app launching. The reference counting API has been in the works for 6+ years to help GLib's bindings/integration with languages utilizing automatic memory management / garbage collection. The more efficient process launching via the use of posix_nspawn() is also exciting for better performance, particularly on systems suffering from memory pressure.

    My Taiwan Travel blog continues! I was expecting the weather to go bad on July 10th, but the typhoon arrived late and the rain only started around 20:00. I'm pretty happy because that means I got to enjoy another beautiful day of hiking in Taroko National Park.

  • 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.
