Ollama + DeepSeek: How I Run LLMs Locally

Mon, 03 Feb 2025 00:00:00 +0000

Why I Use Ollama

I wanted to run LLMs on my own hardware without paying for API calls or sending data to the cloud. Ollama made that straightforward — install, pull a model, start chatting.

Install Ollama

Arch Linux

Update your system, then install Ollama:

sudo pacman -Syu
sudo pacman -S ollama

Enable and start the service:

sudo systemctl enable ollama
sudo systemctl start ollama
sudo systemctl status ollama

You should see active (running).

Odoo on Ubuntu: How I Installed It

Thu, 11 Aug 2022 00:00:00 +0000

What I Did

I installed Odoo (open-source ERP) on Ubuntu for a project. These are the exact steps I ran — all apt commands on Ubuntu.

sudo apt update && sudo apt upgrade

Create an Odoo User

Run this command to create a system user for Odoo:

sudo adduser -system -home=/opt/odoo -group odoo

Install PostgreSQL

Odoo needs PostgreSQL as its database, so install it with:

sudo apt-get install postgresql -y

Create a PostgreSQL User for Odoo

sudo su - postgres -c "createuser -s odoo" 2> /dev/null || true

Install Python Dependencies

Odoo requires some Python packages. Install them with:

Chef Server Setup: What I Did on Ubuntu

Tue, 02 Aug 2022 00:00:00 +0000

Why I Looked Into Chef

Managing servers one by one doesn’t scale. I set up Chef to store server configs as code — a Chef server, a workstation where I write recipes, and a node that pulls its config automatically.

Note: I did this on Ubuntu 18.04 using .deb packages and apt.

Chef Server

The Chef server acts as the central hub for all workstations and nodes under Chef management. Configuration changes made on workstations are pushed to the Chef server, where they are pulled by nodes using chef-client to apply the configurations.

VoIP with Asterisk: My Home Phone Setup on Ubuntu

Tue, 02 Aug 2022 00:00:00 +0000

What I Built

I set up a home VoIP system using Asterisk as the server and Twinkle as the softphone client. Everything here runs on Ubuntu — same network, two extensions, calls between machines.

How VoIP Works

VoIP sends your voice as data over the internet instead of through a phone line. Cheaper than landlines, especially for long-distance — that’s why I tried it.

Asterisk as the Server

Asterisk is the PBX — it handles call routing between extensions. I compiled it from source on Ubuntu.

Creating My First Docker Container

Wed, 27 Jul 2022 00:00:00 +0000

What I Did Here

After installing Docker, I wanted to run an actual Ubuntu container — not just hello-world. The steps inside this post are the same on Arch Linux and Ubuntu hosts. Only the Docker installation differs — see Docker on Arch Linux and Ubuntu for that part.

Arch Linux (host)

Make sure Docker is installed and running on your Arch machine first:

sudo pacman -S docker
sudo systemctl enable --now docker
systemctl status docker

Pull the Ubuntu image

sudo docker pull ubuntu

Create and enter a container

sudo docker run --name my-container -it ubuntu

What those flags mean:

Docker on Arch Linux and Ubuntu: How I Got It Running

Tue, 26 Jul 2022 00:00:00 +0000

Why I Started Using Docker

I wanted a way to run apps without messing up my main system. Docker packs an app with everything it needs into a container — a small, isolated environment that shares my kernel but stays separate from everything else.

If something breaks inside a container, I delete it and start over. No reinstalling the whole OS.

Containers vs Images (Quick Version)

Image — a read-only template (like a recipe)
Container — a running instance of that image (like the actual dish you cooked)

You build or pull an image once. You can spin up as many containers from it as you want.

SSH: How I Connect to Remote Servers

Sat, 14 Aug 2021 00:00:00 +0000

Why I Use SSH

SSH is how I control another machine from my terminal. I use it to manage servers, copy files, and run commands on remote systems without sitting in front of them.

For Windows remote desktop you use RDP. For Linux, SSH is the standard.

How SSH Works (Short Version)

Client — on your laptop (where you type)
Server — on the remote machine (what you connect to)

You run ssh user@ip, enter your password (or use a key), and you get a shell on the remote box.

Dual Boot Ubuntu and Windows: What I Did

Fri, 13 Aug 2021 00:00:00 +0000

Why I Dual-Booted

I needed Windows for some things and Linux for everything else. Instead of picking one, I installed Ubuntu alongside Windows on the same machine. This is the process I followed.

Steps to Dual Boot Ubuntu with Windows

Step 1: Prepare a Bootable USB Drive

Download the latest Ubuntu ISO from the official Ubuntu website.
Download and install Rufus or balenaEtcher to create a bootable USB.
Insert a USB drive (at least 8GB) into your computer.
Open Rufus or balenaEtcher:
- Select the Ubuntu ISO file.
- Choose the USB drive.
- Click “Start” to create the bootable drive.

Step 2: Configure BIOS/UEFI Settings

Restart your computer and enter BIOS/UEFI by pressing a specific key (usually F2, F12, Del, or Esc) during startup.
Look for Boot Order/Boot Priority and set the USB drive as the first boot device.
Disable Secure Boot (if enabled) under the Security tab.
Enable UEFI mode (recommended) instead of Legacy mode.
Save changes and exit BIOS.

Step 3: Boot from the USB Drive

Insert the bootable USB drive into your computer.
Restart the system and press the Boot Menu key (F12, F9, Esc, or as per your motherboard).
Select the bootable USB drive from the list.
Press Enter to boot into Ubuntu Live.

Step 4: Try or Install Ubuntu

Once the Ubuntu installer loads, you will see two options:
- Try Ubuntu – Runs Ubuntu without installing it.
- Install Ubuntu – Proceeds with the installation.
Click on Install Ubuntu to continue.

Step 5: Select Keyboard Layout

Choose your preferred keyboard layout and language.
Click Continue.

Step 6: Connect to Wi-Fi (Optional)

Select your Wi-Fi network.
Enter the password and click Continue.

Step 7: Choose Installation Type

Select Normal Installation (recommended).
Check the box Install third-party software for graphics and Wi-Fi hardware, Flash, MP3, and other media.
Click Continue.

Step 8: Choose Installation Method

Select Something else (for manual partitioning).
Click Continue.

Step 9: Create Partitions for Ubuntu

Ubuntu requires three main partitions:
