Why Everyone should know vim

Filed under

HowTos

Vim is an improved version of Vi, a known text editor available by default in UNIX distributions. Another alternative for modal editors is Emacs but they’re so different that I kind of feel they serve different purposes. Both are great, regardless.

I don’t feel vim is necessarily a geeky kind of taste or not. Vim introduced modal editing to me and that has changed my life, really. If you have ever tried vim, you may have noticed you have to press “I” or “A” (lower case) to start writing (note: I’m aware there are more ways to start editing but the purpose is not to cover Vim’s functionalities.). The fun part starts once you realize you can associate Insert and Append commands to something. And then editing text is like thinking of what you want the computer to show on the computer instead of struggling where you at before writing. The same goes for other commands which are easily converted to mnemonics and this is what helped getting comfortable with Vim. Note that Emacs does not have this kind of keybindings but they do have a Vim-like mode - Evil (Extensive Vi Layer). More often than not, I just need to think of what I want to accomplish and type the first letters. Like Replace, Visual, Delete, and so on. It is a modal editor after all, meaning it has modes for everything. This is also what increases my productivity when writing files. I just think of my intentions and Vim does the things for me.

Migrating to Linux: Network and System Settings

Filed under
HowTos

Linux gives you a lot of control over network and system settings. On your desktop, Linux lets you tweak just about anything on the system. Most of these settings are exposed in plain text files under the /etc directory. Here I describe some of the most common settings you’ll use on your desktop Linux system.

A lot of settings can be found in the Settings program, and the available options will vary by Linux distribution. Usually, you can change the background, tweak sound volume, connect to printers, set up displays, and more. While I won't talk about all of the settings here, you can certainly explore what's in there.

Nintendo Switch hack + Dolphin Emulator could bring GameCube and Wii game support

This week security researchers released details about a vulnerability affecting NVIDIA Tegra X1 processors that makes it possible to bypass secure boot and run unverified code on some devices… including every Nintendo Switch game console that’s shipped to date. Among other things, this opens the door for running modified versions of Nintendo’s firmware, or alternate operating systems such as a GNU/Linux distribution. And if you can run Linux… you can also run Linux applications. Now it looks like one of those applications could be the Dolphin emulator, which lets you play Nintendo GameCube and Wii games on a computer or other supported devices. Read more

Openwashing Leftovers

Linux Foundation: New Members, Cloud Foundry, and Embedded Linux Conference + OpenIoT Summit

  • 41 Organizations Join The Linux Foundation to Support Open Source Communities With Infrastructure and Resources
    The Linux Foundation, the nonprofit organization enabling mass innovation through open source, announced the addition of 28 Silver members and 13 Associate members. Linux Foundation members help support development of the shared technology resources, while accelerating their own innovation through open source leadership and participation. Linux Foundation member contributions help provide the infrastructure and resources that enable the world's largest open collaboration communities.
  • Cloud Foundry for Developers: Architecture
    Back in the olden days, provisioning and managing IT stacks was complex, time-consuming, and error-prone. Getting the resources to do your job could take weeks or months. Infrastructure-as-a-Service (IaaS) was the first major step in automating IT stacks, and introduced the self-service provisioning and configuration model. VMware and Amazon were among the largest early developers and service providers. Platform-as-a-Service (PaaS) adds the layer to IaaS that provides application development and management. Cloud Foundry is for building Platform as a Service (PaaS) projects, which bundle servers, networks, storage, operating systems, middleware, databases, and development tools into scalable, centrally-managed hardware and software stacks. That is a lot of work to do manually, so it takes a lot of software to automate it.
  • Jonathan Corbet on Linux Kernel Contributions, Community, and Core Needs
    At the recent Embedded Linux Conference + OpenIoT Summit, I sat down with Jonathan Corbet, the founder and editor-in-chief of LWN to discuss a wide range of topics, including the annual Linux kernel report. The annual Linux Kernel Development Report, released by The Linux Foundation is the evolution of work Corbet and Greg Kroah-Hartman had been doing independently for years. The goal of the report is to document various facets of kernel development, such as who is doing the work, what is the pace of the work, and which companies are supporting the work.
