VSCodium is a community-driven, freely-licensed binary distribution of Microsoft’s editor VSCode

https://vscodium.com/

Easiest installation if you have flatpak and the flathub repo enabled

flatpak install flathub com.vscodium.codium 

Firefox is after setting the privacy settings correct a good and user-friendly software, but there are better alternatives. For example LibreWolf.

The easiest way IMHO is the flathub installation. First you have to enable the flathub and its repos

https://flatpak.org/setup/Ubuntu/

flatpak install flathub io.gitlab.librewolf-community

flatpak run io.gitlab.librewolf-community

The easiest way is snap

sudo snap install ungoogled-chromium

Ungoogled Chromium retains the default Chromium experience as closely as possible. Unlike other Chromium forks that have their own visions of a web browser, Ungoogled Chromium is essentially a drop-in replacement for Chromium. It also features tweaks to enhance privacy, control, and transparency.

sudo apt -y  install k3b cdda2wav cdrecord mkisofs smake

Open K3b.

Then open the menu, go to settings > Configure K3b > Advanced. Don't forget to check the Advanced GUI!

Go to Programs tab in the settings windows and select cdrecord.

During burning, the project affirm that crdrecord and writing medium is selected.

sudo dd if=/dev/cdrom of=image_name.iso status=progress && sync

or

sudo dd if=/dev/sr0 of=image_name.iso status=progress && sync

You can also use isoinfo to determine the block size, example

isoinfo -d -i /dev/cdrom

dd if=/dev/cdrom bs=2048 count=1621535 of=filename.iso status=progress && sync

And no, you can't copy a Windows ISO like this. Well you can but it wouldn't boot. Just download it as an ISO

ISO use Linux instead of Windows :)

If you have installed libdvdcss2 you can also copy commercial DVDs with brasero which is a gray area, please check your laws.

Unfortunately, Wikimedia and their legal team had inquired Codeberg to strike the WikiLess project with a copyright claim, because Orenom, e.g., Monero, had just slightly altered their logo :(… Come on, man. Facepalm.

Hi, recently I started to perform small screencasts for Linux newbies. I needed a keystroke capturing program. After a swift DuckDuckGo search, I've stumbled upon Screenkey

https://snapcraft.io/screenkey

I've just installed it via snap

sudo snap install screenkey

And I was good to go. I noticed that the indicator seems to be missing. Probably, one has to kill the process via terminal to stop it. :(

I also did a little demo on a Windows 10 system, there I used this program.

https://github.com/bfritscher/carnac/releases/tag/v3-beta

The demo actually demonstrated how to create a Linux live USB stick in Windows to explore Linux :)

There is also keystrokes capturing tool for macOS which can come handy for a screencast KeyCastr

brew install --cask keycastr

What is Proxmox?? 🤔

Proxmox VE is an open-source server management platform for your enterprise virtualization. It tightly integrates KVM hypervisor and LXC, software-defined storage, and networking functionality on a single platform. With the integrated web-based user interface you can easily manage VMs and containers, highly available clusters, or the integrated disaster recovery tools with ease. Proxmox VE is under the GNU Affero General Public License (V3), there is simple subscription structure for those who are interested in more than community support. Simplicity is great advantage of PVE over other virtualization solutions. even a novice user can setup and install it within minutes. And most importantly because it is running on Debian, all Linux experience apply…

This is just a draft for my own further reading and to have something to play with when the time comes found this interesting therefore I put it in there.

Want to learn some network stuff, here are some hints, this is just a draft. I'll hopefully expand this or create an entire new article in depth, when I've the time.

XCP-NG / Xen Orchestra VS Vmware and Why We Choose It For Our Clients

https://www.youtube.com/watch?v=wrLue-ENMJc

There is also EVE-NG. IMHO, Cisco itself has its issues, and personally I'm not a fan of it. Maybe it was in the past the hottest sh*t but currently due to the popularity of Linux there is a whole plethora of alternatives.

IMUNES

Integrated Multiprotocol Network Emulator/Simulator

We developed a realistic network topology emulation / simulation framework based on the FreeBSD and Linux operating system kernel partitioned into multiple lightweight virtual nodes, which can be interconnected via kernel-level links to form arbitrarily complex network topologies.

CORE, CORE: Common Open Research Emulator

The Common Open Research Emulator (CORE) is a tool for emulating networks on one or more machines. You can connect these emulated networks to live networks. CORE consists of a GUI for drawing topologies of lightweight virtual machines, and Python modules for scripting network emulation.

ns-3

What is ns-3?

ns-3 is a discrete-event network simulator, targeted primarily for research and educational use. ns-3 is free software, licensed under the GNU GPLv2 license, and is publicly available for research, development, and use.

The goal of the ns-3 project is to develop a preferred, open simulation environment for networking research: it should be aligned with the simulation needs of modern networking research and should encourage community contribution, peer review, and validation of the software…
