  • Whiteboard Coding Stress Reduces Performance by More than Half

    A recent study by North Carolina State University researchers found that stress caused by whiteboard technical interviews significantly affected the performance of job candidates.

    Whiteboard tests are a common feature of the hiring process for software developers. During these sessions, candidates are expected to develop coding solutions on a whiteboard while describing their decision-making process to observers.

    In the study, half of the participants performed the typical whiteboard test with an interviewer looking on. The other half solved the problem on a whiteboard in a private room with no interviewer present. The private interviews also included a retrospective “think-aloud” session to discuss the solutions presented.

    [...]

    In the paper, the researchers noted that “a technical interview has an uncanny resemblance to the Trier social stress test,” a technique used by psychologists with the sole purpose of inducing stress. “Through a happy accident, the software industry has seemingly reinvented a crude yet effective instrument for reliably introducing stress in subjects, which typically manifests as performance anxiety,” they said. Additionally, “the unique combination of cognitive-demanding tasks with a social-evaluative threat (essentially being watched) is consistent and powerful,” they stated.

  • Address Sanitizer, Part 1

    Hello everyone. My name is Harshit Sharma (hst on IRC). I am working on the project to add the “Address Sanitizer” feature to coreboot as a part of GSoC 2020. Werner Zeh is my mentor for this project and I’d like to thank him for his constant support and valuable suggestions.

    It’s been a fun couple of weeks since I started working on this project. Though I found the initial few weeks quite challenging, I am glad that I was able to go past that and learned some amazing stuff I’d cherish for a long time.

    Also, being a student, I find it incredible to have got a chance to work with and learn from such passionate, knowledgeable, and helpful people who are always available over IRC to assist.

    [...]

    The design of ASan in coreboot is based on its implementation in Linux kernel, also known as Kernel Address Sanitizer (KASAN). However, coreboot differs a lot from Linux kernel due to multiple stages and that is what poses a challenge.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • 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.
