You've probably noticed that I'm really awful with vim and don't do anything in an efficient way. Part of that is due to me never having finished vim tutor so what better way to do that than do it on stream.

This guide explains what is Clipboard, and how to copy file contents into Clipboard without displaying the contents of the file using any text viewer applications in Linux.

What is Clipboard?

You will definitely cut or copy and paste texts on your system multiple times a day. You may not have remembered how many times you copied something or haven't ever thought about where the copied texts are actually stored. But, you should have copied/cut texts so many times. For those wondering, there is temporary place called "Clipboard" in an operating system. Clipboard is the place where the copied/cut data are kept temporarily.

Clipboard is a buffer used for short-term data storage. It is mainly used to transfer data within and between applications, via cut, copy and paste operations. Clipboard is usually temporary and unnamed place that resides in your Computer's RAM.

The clipboards are called "Selections" and there are three types of clipboards available in X11 window system in Linux.

TeamViewer is a cross-platform application that enables an user to control remote computers over the internet or network.

It is used for remote access, remote control, remote support, web conferencing, desktop sharing and file transfer between computers.

TeamViewer is a proprietary computer application, which is free for Private and Non-Commercial use.

It supports multiple Linux distributions and this article shows how to install TeamViewer on Ubuntu, Fedora, and Red Hat systems.

My home network is extremely slow, because I have CAT5e cables everywhere. I was wondering if I can use Thunderbolt ports which I have both on the new Mac M1 and Intel NUC with Fedora. So without my breath, since some Thunderbolt docks are known to brick the new Macs, I connected the two guys. And it worked automatically!

I have neglected the Valutakrambod library for a while, but decided this weekend to give it a face lift. I fixed a few minor glitches in several of the service drivers, where the API had changed since I last looked at the code. I also added support for fetching the order book from the newcomer Norwegian Bitcoin Exchange.

I alsod decided to migrate the project from github to gitlab in the process. If you want a python library for talking to various currency exchanges, check out code for valutakrambod.

LXD is a hypervisor to run both system containers (a la LXC) and virtual machines (a la QEMU) on Linux distributions. System containers are lightweight because they are based solely on the Linux kernel for their virtualization features, and support Linux guests only. However, virtual machines can run other operating systems. In this post, we see how to run Windows in a LXD virtual machine.

The benefit with running Windows through LXD is that you are using the familiar LXD workflow and takes away some of the the complexity from the other ways of running a VM (like virt-manager).

The content of this tutorial came from https://discuss.linuxcontainers.org/t/running-virtual-machines-with-lxd-4-0/7519 Look towards the end of the thread where Stéphane Graber describes how to simplify the process compared to the instructions at the top of that thread.

The prerequisite is that you have LXD configured and running.

From Apt-get to Synaptic Package Manager, there are many ways to uninstall packages in Debian Linux. In this guide, we’ll show you all the ways you can uninstall packages from your Debian Linux system.

The Wine team announced the new development release Wine 6.3 with new features and various bug-fixes.

I‘m running nginx as a frond end to php based Apache+mod_fastcgi server. My app lets user upload images upto 2MB in size. When users trying to upload 1.5MB+ size image file using nginx reverse proxy, they are getting the following error on screen:

Nginx 413 Request Entity Too Large

How do I fix this problem and allow image upload upto 2MB in size using nginx web-server working in reverse proxy or stand-alone mode on Unix like operating systems?

How can I check if a file does not exist in a Bash script?

We can quickly tell if a standard file does not exist in Bash using the test command or [ builtin. This page explains how to find a regular file under the Linux or Unix-like system using Bash.

Open source database migration typically involves more than just a database. It is more accurately described as a database ecosystem transition, which can include multiple independent projects for management, monitoring, tuning, connection pooling, high availability and third-party support. Beyond the database ecosystem, application integration with the database may be impacted as well.

The appeal of open source databases, particularly for smaller non-mission-critical systems, has led to increased adoption and market popularity.

Zulip’s 3.0 release back in July saw over 100 people contribute from all over the world. It also brought support for Ubuntu 20.04, so we fired up our server to see just how easy it is to install and if it could restore our faith in chat. We’re pleased to say it’s super easy and we strongly recommend adding it to your server, too.

The two key bits of terminology to grasp are streams and topics. Streams are a broader hierarchy and can be thought of as separate chatrooms. 

Different members of your team can be members of different streams, and streams can be made private so that only certain people can see them. Within a stream every message has its own topic and conversations will appear threaded thusly, rather like email subject lines.

However, unlike email subject lines you can’t be lazy and have a blank thread. This tiny bit of extra effort is what enables everything to be so nicely organised, so that you can enjoy hassle-free open source messaging whether in real time or asynchronously, perhaps catching up on messages from your colleagues in other time zones.
