  • Build a FIX engine using Quickfix/J and Quarkus

    If you have spent any time in a trading organization, whether foreign exchange (FX), commodities, or equities, there's a good chance you've encountered the Financial Information eXchange (FIX) protocol. FIX is a socket-based, asynchronous message protocol designed for electronic trading. The protocol is implemented and used across all the major exchanges, such as NYSE, NASDAQ, CME, and ICE. FIX provides an API to broker-dealers and retail customers to obtain security definitions, submit and manage orders, and receive events such as trades.

    This article guides you through the steps to develop a basic application that can exchange financial information over the FIX protocol in a Java application using the QuickFIX/J engine. We'll use Quarkus to gain access to the many conveniences this framework offers.

  • Stories from the amazing world of release-monitoring.org #12

    The realm of release-monitoring.org looks quiet from the top of my tower but there are plenty of activities happening below. I turn back from the window and went back to my table, various papers lying on it. All the bugs from Bugcronomicon with a few of my notes lying around. There is a lot of them ending on my table! I’m trying to address them all, but there are too many of them.

    [...]

    As you might already know, Anitya is using social_auth-flask as the authentication library to authenticate users with external authentication servers (in our case it’s Fedora Account System (FAS)). As you can see in the repository, this library hasn’t been updated for a long time and now we are hitting some issues. I tried to fix this and my pull request got merged, but the contributor with permissions to release a new version isn’t active anymore.

    So, what is the issue? If you try to login to purgatory (staging instance of Anitya), you will be treated with an Internal Server Error, which is caused by the issue mentioned above.

    The conclave of mages decided to migrate to another authentication library and this work is currently in progress. Until the migration is done, I don’t want to release a new version of Anitya in production. I’m sorry for the inconveniences that this situation is causing.

  • 3 ways I configure SSH for privacy | Opensource.com

    SSH (Secure Shell) is a protocol that enables you to create a verified and private connection, securing the channel using cryptographic keys, to launch a remote shell on another machine. Using this connection, you can execute remote commands, initiate secure file transfers, forward sockets and displays and services, and much more.

    Before the appearance of SSH, most remote administration was done over telnet, and to be fair, once you could establish a remote session, you could do practically whatever you need. The problem with this protocol was that traffic traveled unencrypted as pure plaintext. It didn't take much effort to use a traffic sniffer to see all the packets within a session, including those containing a username and password.

    With SSH, thanks to the use of asymmetric keys, the sessions between the apparatus involved in the communication are encrypted. And nowadays this is more relevant than ever, with all the cloud servers getting administered from all over the world.

  • View your Linux server's network connections with netstat | Opensource.com

    I shared some important first steps to help manage your personal Linux server in a previous article. I briefly mentioned monitoring network connections for listening ports, and I want to expand on this by using the netstat command for Linux systems.

    Service monitoring and port scanning are standard industry practices. There's very good software like Prometheus to help automate the process, and SELinux to help contextualize and protect system access. However, I believe that understanding how your server connects to other networks and devices is key to establishing a baseline of what's normal for your server, which helps you recognize abnormalities that may suggest a bug or intrusion. As a beginner, I've discovered that the netstat command provides important insight into my server, both for monitoring and network troubleshooting.

    Netstat and similar network monitoring tools, grouped together in the net-tools package, display information about active network connections. Because services running on open ports are often vulnerable to exploitation, practicing regular network monitoring can help you detect suspicious activity early.

  • Hybrid work: 5 tips for prioritizing the employee experience

    Companies everywhere talk about how important the customer experience is, and they’re not wrong – it’s a top priority for us, too, because without our customers, we’d be out of business. But at Clario, we place just a little more importance on driving an exceptional employee experience.

    I’ve found that employees who are invested, feel recognized and challenged, have a sense of fun, and feel tied to the mission of the organization tend to deliver an outstanding customer experience. The quality of the product they deliver is better, the way they support customers is better, and they’re more empathetic toward the customer and what they experience every day. When you have invested employees, all of that comes a little easier.

    Having a superior employee experience is important for a variety of reasons, especially given today’s hypercompetitive job market. It’s easier than ever to find a new job, which is why it’s so critical to work on elevating the experience your own employees have every day. We do this by cultivating a workforce that values diversity and inclusion and ensuring that they’re doing meaningful work, feel recognized, are compensated well, and have a transparent career path.

  • Transitioning Red Hat’s finance leadership

  • Growing the open source talent pipeline with HBCUs

    When conversations around DEI within the technology industry are brought up, often what you hear is a lack of a strong pipeline or challenges with finding qualified, diverse talent to fill job openings. Having a diverse talent pool is no longer a nice-to-have, it’s a must-have in order to maintain innovation and continue to drive business forward. At Red Hat, we face the same issues and what we have found is that in order to find diverse talent, we need to go to where the talent is.

  • 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.
