  • Introduction to Bash Scripting Tutorial

    Linux Shell Scripting is & always has been one of the most desired skills that a System Administrator and now DevOps engineers are required to have. It has been used by Linux experts to perform all sorts of tasks, especially repetitive tasks or for automating tasks.

    Consider this post as the central reference point for all Scripting tutorials published here at The Linux GURUS. This scripting tutorial just provides a brief about scripting & why we require it. Mentioned below is the list of all tutorials to get yourself started with & master it.

  • Bash scripting – Understanding Linux Environment variablesBash scripting – Understanding Linux Environment variables
  • Bash Scripting-2- Using VARIABLES in Linux shell scripts
  • Bash scripting – 3 – Performing Arithmetic Operation in shell script
  • Python for Beginners: Making Your First Socket Program (Client & Server Communication)

    Sockets in Python have always been something I see online and thing "Why is this complex"? "Shouldn't there be a simple way to get started with sockets"? So I decided to make a tutorial myself: However, just like everything in coding, there can be varying levels of compelxity and different implementations for the same tech. Today we are going to look at one simple example for beginners that can help you dive into the vast world of sockets and Python as a whole.

  • Small python application which will remove duplicate files from the windows 10 os [Ed: Windows sadly]

    I am glad to inform you all that the remove duplicate file project written with python has finally completed and now it will be uploaded to GitHub for your all to enjoy. This is free software and it will always remain free. Although I would really love to create a Linux version of this remove duplicate file’s software, but I do not have a Linux os’s computer therefore at the moment this software is just for the windows user only. I have packed this software up where you can just download the setup.exe file and then install the program and start it up to search and destroy the duplicate files inside your computer. Here are the steps you need to do to search and destroy the duplicate files:

    I grew up in Dartmouth, Nova Scotia, Canada and stayed there until my late twenties. My Bachelor and PhD degrees were both in biochemistry, focused on structural biology. I did travel a lot for chess, winning a few notable tournaments in my early teen years and achieving a master rating in Canada by my late teens. Dartmouth is also known as the “City of Lakes,” and I grew up paddling on the nearby Lake Banook. In the cold Canadian Winter the lake would freeze over and training would switch to a routine including distance running—this is where my biggest “hobby” really took off. I still run about 11 miles daily in the early morning.

    I did an almost six year post-doc in Oxford, United Kingdom. I had started to realize during my PhD that my skill set was better suited to computational work than work on the lab bench. Formally, I was still a biol- ogist while at Oxford, but it was becoming clear that my contributions were starting to look a lot more like applied computer science and computational geometry in particular. I was recruited to Los Alamos National Labora- tory to work on viruses (the kind that make a person, not computer, sick), but ultimately my job has evolved into applied computer scientist here, and nothing beats distance running in beautiful Santa Fe, NM.

  • Started work on getting py-spy/speedscope in RunSnakeRun

    So having finally written down the thoughts on a carbon tax, that kept distracting me from actually working on Open Source, I finally got a bit of work done on Open Source on the last night of the vacation.
    What I started work on was getting a sampling profiler format supported, and for that I chose py-spy, particularly its speedscope export format. The work is still early days, but it does seem to work in my initial test cases.

AMD: Ryzen, AMDGPU and More

  • ASUS TUF Laptops With Ryzen Are Now Patched To Stop Overheating On Linux

    The AMD Ryzen Linux laptop experience continues improving albeit quite tardy on some elements of the support. In addition to the AMD Sensor Fusion Hub driver finally being released and current/voltage reporting for Zen CPUs on Linux, another step forward in Ryzen mobile support is a fix for ASUS TUF laptops with these processors.

  • AMD Sends In A Bunch Of Fixes For Linux 5.6 Along With Pollock Support

    After already several rounds of feature work queued in DRM-Next for Linux 5.6, AMD has submitted a final batch of feature work for this next kernel as it concerns their AMDGPU graphics driver. While Linux 5.6's merge window isn't opening until around the start of February, with RC6 having come, it effectively marks an end to the feature window of DRM-Next for targeting the next kernel. AMD's final pull request is mostly centered on fixes plus a few other extras and also enabling AMD Pollock display/graphics support for that forthcoming hardware.

  • The AMD Ryzen Thermal / Power Linux Reporting Improvements Working Well - V2 Up For Testing

    A few days ago I reported on AMD's "k10temp" Linux kernel driver finally seeing the ability to report CCD temperatures and CPU current/voltage readings as a big improvement to this hardware monitoring driver. The work hasn't yet been queued for inclusion into the mainline kernel, but initial testing is working well and a second revision to the patches has been sent out. Linux HWMON maintainer Guenter Roeck who spearheaded this work independent of AMD sent out the "v2" k10temp driver improvements on Saturday. This allows core complex tie temperature reporting for Zen 2 CPUs and allows current and voltage reporting for Ryzen CPUs. While this information has long been available to Windows users, sadly it's not been the case for Linux at least as far as mainline drivers go -- the out-of-tree Zenpower driver and other third-party attempts have been available but nothing mainline.

Intel's OSPray 2.0 Ray-Tracing Engine Released

An area where Intel continues striking with rhythm and near perfection is on the open-source software front with their countless speedy and useful open-source innovations that often go unmatched as well as timely hardware support. Out this weekend is their OSPray 2.0 release for this damn impressive ray-tracing engine. OSPray 2.0 is out as their latest big upgrade to this open-source ray-tracing engine that supports photo-realistic global illumination, MPI for exploiting large system performance, volume rendering, and is all open-source software. OSPray 2.0 is another big advancement for this project that is part of Intel's growing oneAPI tool-kit. Read more

  • webcompat.com: Project belt-on.

    So last week, on Friday (Japanese time), I woke up with a website being half disabled and then completely disabled. We had been banned by GitHub because of illegal content we failed to flag early enough. And GitHub did what they should do. Oh… and last but not least… mike asked me what Belt-on meant. I guess so let's make it more explicit.

  • Units of Measure in Rust with Refinement Types

    Years ago, Andrew Kennedy published a foundational paper about a type checker for units of measure, and later implemented it for F#. To this day, F# is the only mainstream programming language which provides first class support to make sure that you will not accidentally confuse meters and feet, euros and dollars, but that you can still convert between watts·hours and joules.

  • This post focuses on the work I accomplished as part of the Treeherder team during the last half of last year.

    The Taskcluster team requested that we stop ingesting tasks from the taskcluster-treeherder service and instead use the official Taskcluster Pulse exchanges (see work in bug 1395254). This required rewriting their code from Javascript to Python and integrate it into the Treeherder project. This needed to be accomplished by July since the Taskcluster migration would leave the service in an old set up without much support. Integrating this service into Treeherder gives us more control over all Pulse messages getting into our ingestion pipeline without an intermediary service. The project was accomplished ahead of the timeline. The impact is that the Taskcluster team had one less system to worry about ahead of their GCP migration.

Python Programming Leftovers

  • The tiniest of Python templating engines

    In someone else's project (which they'll doubtless tell you about themselves when it?s done) I needed a tiny Python templating engine. That is: I wanted to be able to say, here is a template string, please substitute a bunch of variables into it. Now, Python already does this, in about thirty different ways, and str.format or string.Template do most of it as built-in.

  • How to set a variable in Django template
  • Why ASGI is Replacing WSGI in Django

    When I first learnt about how to deploy my Django website. I took the easy route which was deploying it on Heroku. There's literally tons of tutorial on how the process of deploying it work. Heck, there was even a book about the benefits of deploying Django using Heroku. Soon in my own work, I needed to deploy my own Django project. It was working well for a bundled development grade web server. I thought to myself, why not find a better way on a production-grade web server. Instead of just a miserable default web server that is not production-grade. My journey in searching on deploying Django started for me. Which if you look at multiple tutorial references they still suggest the use of Heroku or Digital Ocean.
