Desktop Environments 2023
Around April 2023, I decided to look for a new Linux Desktop Environment for my personal void linux. So I tried these distros: lxqt: This is the one I eventually chose to switch to. I liked it that it was very small and light, and very modular, almost like a kit that you assemble yourself. Because I have thinking for some time that I would like to make my ...
Secure erase of disc drives
This article is about erasing disc drives securely. Specially for SSD drives, writing zeros or random data to discs is not good enough and counterproductive. One way to do secure erase (for disposal) is to begin with an encrypted disc. However, after the fact the following options are possible: ATA Secure Erase ...
Anti Roboto skills
Losing your job to robots is no longer a sci-fi fantasy. Some estimates say, robots may take over more than five million jobs across 15 developed countries. Machines could account for more than half the workforce in places like Cambodia and Indonesia, particularly in the garment industry. While such information has led many people to seek out higher-tech ...
Managing our personal finances
During my last vacation I wanted to move how we manage our personal finances away from the ad-hoc spreadsheet that we had been using for the past few years. I envisioned something server side, so I wouldn't need to add software on my wife's computer. And initial quick run through of server side software did not yield anything that interested me. In general I could only find full accounting applications, which ...
Starting with 3D Printing
So I finally tried my hand at 3D printing. Obviously I did not buy at 3D printer. These are either quite expensive or you need to assemble them yourself, which I don't think is in my capacity level. To get started, you first need a 3D model to print. There are several 3D models available in Thingieverse, however I actually wanted to make my own model. After all, that is the whole point of 3D printing. Custom made parts/objects that can be printed as needed. To create a 3D model you need some 3D modelling software. For my very first model I opted for TinkerCAD. This is software that runs on the cloud that lets you create your own 3D models. This is particularly interesting because you don't need to install anything on your computer and it would essentially run on anything where a web browser runs. For a web based application, it is quite responsive and feature-full. You can use (like me) a facebook account to sign-in. Models can then be downloaded as an ".stl" file (the format used by 3D printers) or send directly to 3D printing service such as 3D Hubs. 3D Hubs, is an online 3D Printing service which facilitates transactions betwen 3D Printer owners (Hubs) and people who want to make 3D prints. Printer owners can join the platform to offer 3D printing services while customers can locate printer owners to get their 3D models printed nearby. ...
Windows administration from the command line
Windows system administration is very mouse driven and to reach all tools you need to browse through Windows explorer. If you are like me and prefer to log on a limited privilege account and use Runas to perform admin tasks, you can open these consoles with the .msc file names. Here is a list of admin tools with their .msc file names. domain.msc: AD Domains and Trusts ...

Raspberry Pi Weekend project
So finally took the time to try out a Raspberry Pi. For this weekend project wanted to do something relatively simple. Essentially, I wanted to recreate/enhance the functionality of a TL-WR702N. The TL-WR702N Nano Router is a neat device but being closed, can not be customized to what I wanted. It can be used in the following modes: ...

Remote Bridging
Sometimes we need to connect two or more geographically distributed ethernet networks to one broadcast domain. There can be two different office networks of some company which uses smb protocol partially based on broadcast network messages. Another example of such situation is computer cafes: a couple of computer cafes can provide to users more convinient environment forr playing multiplayer computer games without dedicated servers. Both sample networks in this article need to have one *nix server for bridging. Our networks can be connected by any possible hardware that provides IP connection between them. Connecting Two Remote Local Networks With Transparent Bridging Technique Short description In described configuration we are connecting two remote LANs to make them appearing as one network with 192.168.1.0/24 address space (however physically, presense of bridges in network configuration is not affecting IP protocol and is fully transparent for it, so you can freely select any address space). Both of the bridging servers has two network interfaces: one (as eth0 in our example) connested to the LAN, and second (eth1) is being used as transport to connect networks. When ethernet tunnel between gateways in both networks will be bringed up we will connect tunnel interfaces with appropriate LAN interfaces with bridge interfaces. Schematically this configuration can be following: ...

Automatically adding systems to an AD domain
When using virtualisation it is very common to create template VMs that can be cloned from. This makes deployment much easier than having to install a new VM from scratch. Unfortunately, the cloned VMs lack any Active Directory memberships and the VMs have to be manually added to the AD domain. For automated deployment scenarios this is less than desirable. This recipe intends to solve that issue in a ...
