  • Beat imposter syndrome by developing ‘true confidence’ as a software engineer

    Let me start this post off by saying that impostor syndrome has already been covered profusely and at length, and there’s probably nothing new I can add to the discussion, so let me stop here, thanks for reading, and sorry for wasting your time.

    [...]

    “But I don’t know anything about Flask or Django or how to author a pip package, and I don’t know the difference between Python 3 and Python 2, and I’ve never used the collections package, and sometimes when I laugh too hard, I pee myself a little bit.”

  • Colin Walters: tar::Builder isn’t Send

    I recently made a new project in Rust that is generating multiple bootable operating system disk image types from a "pristine" image with the goal of deduplicating storage.

    At one point I decided to speed it up using rayon. Each thread here is basically taking a pristine base (read-only), doing some nontrivial computation and writing a new version derived from it. The code is using .par_iter().try_for_each(); here the rayon crate handles spinning up worker threads, etc.

    That all worked fine.

  • [Old] Why I wrote Net::Google::CivicInformation

    Before I became a computer programmer, I tried my hand at being a human programmer, in the form of a wordsmith, as I called myself then. I had various jobs as a writer, editor, translator and journalist, but I met with little success, for two main reasons. In those days you needed a publisher to find your work interesting enough to publish before anyone could read it, and that was a pretty high bar. And in the second place, it was difficult to get the humans to react to the content I wrote (I’m still exercised that the movie reviewer would get more letters to the editor than I did after a political exposé that took a month to produce).

    I still remember the moment of awe and inspiration in early 1994 or so, when after acquiring a sparkly new i286 PC at Circuit City, I discovered the World Wide Web and its promise of a world free of publishers and constraining editors. I jumped right in and became one of the first “webmasters,” which led to a job where I needed to learn Perl. Over a short time I began to thrill more at the construction of the engine to publish the content than at the creating of it. I still had the barrier-free entry point, and as to my second gripe … well, I found that computers respond much more predictably to my writing than humans ever did.

  • [Older] Interview: Trying to Catch Paul "LeoNerd" Evans

  • Downloading and Installing Perl in 2021

    If you’re reading this article, you’re likely looking for a simple way to download and install the Perl programming language. Or you already have Perl installed as part of your operating system, but it’s older than the currently-supported versions (5.32.1 or 5.30.3) and you’d like to use the latest and greatest features. The download options may seem daunting, especially if you’re new to computers or programming. We’ll take things step by step, and soon you’ll be on your way to writing your first Perl program.

    A word of warning, though: Several of these steps (and usually Perl itself) require using your computer’s command-line or terminal interface.

  • Logistic Regression in Python – Linux Hint

    Logistic regression is a machine learning classification algorithm. Logistic regression is also similar to linear regression. But the main difference between logistic regression and linear regression is that the logistic regression output values are always binary (0, 1) and not numeric. The logistic regression basically creates a relationship between independent variables (one or more than one) and dependent variables.

  • 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.
