Gentle introduction to Tmux

Sat, 26 Apr 2025 00:00:00 +0000

In our research lab we just had a new high-performance computing machine. However this is where the good news end, since we are having our networking infrastracture redone we are facing some challenges while trying to train voilance detection model. The networking constraints we have right now are:

No remote access: The machine is only accessible through the local network, with no internet connectivity.
Unstable network: The local network is shaky and unreliable.
Shared hardware: We are sharing the hardware with other lab members.

These limitations make it challenging to maintain long-enough sessions since the training would take hours (maybe days).

Buring ISO into a Flash USB on Linux

Fri, 04 Oct 2024 00:00:00 +0000

Burning an ISO to a Flash USB stick or a CD/DVD is the first step to install a new operating system on a machine, and it is a straight-forward process too. For example, when I used to use Windows operating systems, Rufus was my first choice to burn an ISO image, and on debian or Ubuntu, it was Etcher. However, now that I’m using Arch Linux, both of them didn’t work or weren’t even available.

Connecting a qemu virtual machine to the host machine

Tue, 02 Apr 2024 00:00:00 +0000

Using a qemu virtual machine that was created feels just like using any other physical machine until it’s time for remote access, or doing any networking-related activities( ports, IP address, etc… ). then you realize that it is connected using NAT. meaning you do not have access to the machine, can’t ssh into it, or connect to any of its ports.

Now What to do:#

Generally speaking, there are two ways we could achieve connectivity between the host machine and the guest virtual machine, the first approach is using Port-Forwarding, which gives us the ability to make a mapping between a port on the guest machine to a port on the host machine. The other solution is attaching the guest machine to a Bridge Network, making the host and guest machines fully connected.

Cross-platform mobile development on Linux

Thu, 28 Mar 2024 00:00:00 +0000

I have always heard about cross-platform mobile development frameworks(React-native & flutter), and how they make it trivial to maintain a single code base for your application. But how true of a statement is it when it comes to someone on Linux wishing to develop an application with some native networking features?

It is true to some extent:#

Two years ago I was working on my thesis and it involved creating a simple mobile application to act as a client for an ML prediction model, on that project I didn’t need any native support and it was only a prototype, which meant I only build it on android. so theoretically I could have built it for ios using any cloud service since you need an Apple machine to build it.
