Run Your Own ChatGPT-Like AI on Linux for Free with Ollama [SOLVED]

noreply@blogger.com (Amit Naik) — Sun, 21 Dec 2025 09:43:00 -0800

Tired of paying for ChatGPT or worrying about your data in the cloud? In 2026, you can run powerful AI models locally on your Linux machine completely offline and private using Ollama.

Ollama makes it dead simple to download and run open-source large language models (LLMs) like Llama 3.2, DeepSeek-R1, Gemma 3, or Qwen. No complex setup, and it supports NVIDIA GPU acceleration for fast responses.

Lets talk about it!! I will cover below points:

Installing Ollama on Ubuntu/Fedora/other distros
Enabling NVIDIA GPU support (common issues fixed!)
Downloading and running models
Basic usage and tips
Optional: Web UI for a ChatGPT-like interface

Step 1: Install Ollama

The easiest way is the official one-liner script (works on most Linux distros):

curl -fsSL https://ollama.com/install.sh | sh

This downloads and sets up Ollama as a service. After it finishes, verify:

ollama --version

You should see something like "ollama version 0.x.x".

Ollama now runs in the background: systemctl status ollama (or start it manually with ollama serve in a terminal).

Step 2: Enable NVIDIA GPU Acceleration (If You Have an NVIDIA Card)

Ollama auto-detects NVIDIA GPUs with recent drivers no need to install full CUDA toolkit separately.

First, ensure drivers are installed:

On Ubuntu: sudo ubuntu-drivers autoinstall then reboot.
Verify: nvidia-smi (should show your GPU and driver version).

Common issues & fixes:

"No GPU detected" → Reinstall Ollama after drivers: run the install script again.
Old drivers → Update to latest (535+ recommended).
After suspend/resume, GPU lost → Restart Ollama service: sudo systemctl restart ollama.
Multiple GPUs → Limit with export CUDA_VISIBLE_DEVICES=0 (replace 0 with your GPU ID).

When you run a model, check usage with nvidia-smi or nvtop (install via sudo apt install nvtop).

Step 3: Download and Run a Model

List popular models: ollama list (or browse https://ollama.com/library)

Start with a fast one:

ollama pull phi3 # Small & quick (3.8B params, great for beginners) ollama pull llama3.2 # Meta's latest, excellent general-purpose ollama pull gemma3 # Google's new powerhouse ollama pull deepseek-r1 # Top reasoning model in 2025

Larger ones (e.g., :70b) need more RAM/VRAM (16GB+ recommended).

Run it:

ollama run llama3.2

Then chat! Type prompts and hit Enter. Exit with /bye.

Example:

>>> Explain quantum computing simply

Pro Tip: Quantized models (e.g., llama3.2:8b) are faster on modest hardware.

Step 4: Optional - ChatGPT-Like Web Interface (Open WebUI)

For a beautiful browser UI:

docker run -d -p 3000:8080 --add-host=host.docker.internal:host-gateway -v open-webui:/app/backend/data --name open-webui --restart always ghcr.io/open-webui/open-webui:main

Open http://localhost:3000, sign up, and connect to Ollama (it auto-detects).

Common Problems [SOLVED]

Slow on CPU only → Get NVIDIA drivers working!
Out of memory → Use smaller model (e.g., :3b or :8b) or add swap.
Model download stuck → Check internet; retry with ollama pull <model>.
Service not starting → journalctl -u ollama for logs.

Conclusion:

You've now got your own private AI running locally faster than cloud for many tasks, zero cost, full privacy.

Start experimenting! Try coding help with deepseek-coder or image understanding with llava.

Share your experiences in the comments. What model are you running?

FIXED : ChatGPT is at capacity right now

noreply@blogger.com (Amit Naik) — Wed, 25 Jan 2023 03:28:00 -0800

ChatGPT is at capacity right now

Chat GPT has taken the world by storm ever since it became available to the public.

What is this?

ChatGPT is, quite simply, the best artificial intelligence chatbot ever released to the general public. It was built by OpenAI, the San Francisco A.I. company that is also responsible for tools like GPT-3 and DALL-E 2, the breakthrough image generator that came out this year.

How to fix ChatGPT is at capacity right now ?

There are many reason behind chat GPT unavailability. Refer to below list.

1. You should not be accessing chatGPT from Russia, China, Egypt, Iran, Ukraine as its not available in these countries yet. You need to use VPN.

2. If you are seeing "ChatGPT is at capacity right now" then just keep refreshing the page or access it during off-peak hours.

3. I have also experienced that ChatGpt team banned all aws IP's. Meaning you can't access ChatGpt from aws instances. You will get Access Denied error code 1020. Here also you need to use good VPN. Try using Opera browser with their in-built VPN feature (its free of cost)

4. Also do try chatGPT from browsers incognito/private mode. Because there will be no cache, cookies saved while accessing chatGPT.

5. Do provide your email id at "Get notified when we're back". This will send you email once it gets free.

How to loop through the content of a file in Bash [SOLVED]

noreply@blogger.com (Amit Naik) — Thu, 4 Jul 2019 03:07:00 -0700

I saw that many people face the problem to loop through the file content in Bash.
I have some solutions for this. There are many ways through you can achieve this.
You can choose the one which suits you.

Option No.1

while IFS="" read -r p || [ -n "$p" ]
do
  printf '%s\n' "$p"
done < peptides.txt

If your file has leading whitespace, interpretting backslash sequences, and you want to skip the trailing line then above solution is for you.

Option No. 2

#!/bin/bash
filename='peptides.txt'
echo Start
while read p; do 
    echo $p
done < $filename

above option is a while loop option. Single line at a time. Input redirection.

Option No. 3

#!/bin/bash
filename='peptides.txt'
exec 4<$filename
echo Start
while read -u4 p ; do
    echo $p
done

Above one is also in while loop: Single line at a time:
Open the file, read from a file descriptor (in this case file descriptor #4).

Option No. 4

while IFS= read -r line; do
   echo "$line"
done <file

Above option is with simple while loop. You need to set the IFS properly, otherwise you will loose the indentation. Also always use the -r option with read. NEVER EVER use the for loop for reading lines.

I hope these options are helpful for you. 😃

Let me know your feedback!

How to symlink a file in Linux? [SOLVED]

noreply@blogger.com (Amit Naik) — Thu, 25 Apr 2019 01:47:00 -0700

How to create symlink for a file/directory ?

Today I will show you how to create a symlink to a file or folder.
In linux, a symbolic link, also known as a symlink or a soft link, is a special kind of file (entry) that points to the actual file or directory on a disk (like a shortcut in Windows)

So lets create one:

in order to create a new symlink try below

ln -s /path/to/file /path/to/symlink

To create or update a symlink:



ln -sf /path/to/file /path/to/symlink












How to list all symlink in a directory ?

Now you have created a symlink. To see present symlink for current directory you can try below command:





ls -la /var/www/ | grep "\->"






This will list all the links present in the current directory.







Let me know if this resolves your problem 😃

Search in all files for specific string on Linux [SOLVED]

noreply@blogger.com (Amit Naik) — Fri, 19 Apr 2019 05:08:00 -0700

If you want to search a word in all of your files on your linux you need to run grep command. This command has some parameters. All explained below:

grep -rnw '/path/to/somewhere/' -e 'pattern'

-r or -R is recursive,
-n is line number, and
-w stands for match the whole word.
-l (lower-case L) can be added to just give the file name of matching files.

Along with these, --exclude, --include, --exclude-dir flags could be used for efficient searching:

This will only search through those files which have .c or .h extensions:
```
grep --include=\*.{c,h} -rnw '/path/to/somewhere/' -e "pattern"
```
This will exclude searching all the files ending with .o extension:
```
grep --exclude=*.o -rnw '/path/to/somewhere/' -e "pattern"
```
For directories it's possible to exclude a particular directory(ies) through --exclude-dirparameter. For example, this will exclude the dirs dir1/, dir2/ and all of them matching *.dst/:
```
grep --exclude-dir={dir1,dir2,*.dst} -rnw '/path/to/somewhere/' -e "pattern"
```

This works very well for me, to achieve almost the same purpose like yours.

For more options check man grep

There appears to be trouble with your network connection. Retrying... [SOLVED]

noreply@blogger.com (Amit Naik) — Fri, 19 Apr 2019 04:44:00 -0700

So recently I was facing an issue while adding Yarn package to my application. Every time I was doing Yarn add it was showing me error like There appears to be trouble with your network connection. So problem is, this happens when your network is too slow or the package being installed is too large, and yarn just assumes it's a network problem. Lets try increasing Yarn network timeout!

To resolve this problem all you need to do is:

yarn add <yourPackage> --network-timeout 100000

Now if problem still exists then you need to add proxy.
To add proxy just do below.

$ yarn config set proxy http://your_company_proxy_url:port
$ yarn config set https-proxy http://localhost:3128

example $ yarn config set https-proxy http://proxy.example.com:8080

Add a comment below if problem still exists :) Will be happy to help you!

Error: Apache shutdown unexpectedly [SOLVED]

noreply@blogger.com (Amit Naik) — Thu, 2 Apr 2015 06:38:00 -0700

Hello Guys,

So, I have been installing XAMPP on my office windows 8 machine and it didn't worked in first attempt. I knew it something is wrong with ports/config settings.
When I clicked on 'Start' button of XAMPP control panel, it showed me below error.

Error: Apache shutdown unexpectedly.
This may be due to a blocked port, missing dependencies,
improper privileges, a crash, or a shutdown by another method.
Press the Logs button to view error logs and check
the Windows Event Viewer for more clues
If you need more help, copy and post this
entire log window on the forums

Problem detected!
Port 80 in use by "Unable to open process" with PID 4!
Apache WILL NOT start without the configured ports free!
You need to uninstall/disable/reconfigure the blocking application

or reconfigure Apache and the Control Panel to listen on a different port

Please follow the steps to solve this problem:

1) From XAMPP control panel click on Apache 'config' button.

2) Now, httpd.conf file will be opened in text editor.

3) Find (Control + F) Listen 80 replace it to Listen 8080

4) Again find ServerName localhost:80 replace it to ServerName localhost:8080

5) Now save the file and go to XAMPP control panel and click on 'Start' button.

6) Now go to http://localhost:8080 you should see XAMPP index page.

Congratulations: You have successfully installed XAMPP on your system! :)

So how did it worked ?

Your port 80 was busy and we are now using unique port i.e. 8080

So remember whenever you are going to access the localhost you will be using it like http://localhost:8080 same for phpmyadmin http://localhost:8080/phpmyadmin/

If you insist with default port 80 then you need to look in your computer and find which installed software is using port 80.

e.g. skype uses default port 80.

To clear that port, open skype then go to Tools > Options > Advanced > Connection > and in that uncheck 'Use port 80 and 443 for additional incoming connections' option. Then save it and restart the skype. Now your skype will use another unique port.

Thats how you can clear port 80.

Helpful ? comments please :)

How to Install Ruby on Rails on Ubuntu [SOLVED]

noreply@blogger.com (Amit Naik) — Wed, 28 Aug 2013 03:33:00 -0700

Hello Everyone,

Yesterday I have installed the Ruby on Rails on my Ubuntu 12.04. It is really a fun! I think I should share it!

So following are the steps to install Ruby on Rails on Ubuntu!

1) When you are installing something you should always run the

sudo apt-get update
This will make sure that we have all packages installed and up to date :)

2) After update you should install RVM ( Ruby Version Manager ) Now, RVM is really a cool unix-like software platform designed to manage multiple installations of Ruby on the same device. You can install RVM using CURL only. So very first, you have to make sure that CURL is installed on your ubuntu.
Just run below command to install CURL
sudo apt-get install curl

Now after CURL you can install RVM with below command
\curl -L https://get.rvm.io | bash -s stable

3) Now you have successfully installed Ruby Version Manager! Now lets install Ruby! But wait, before that have you checked the dependencies for RVM ? You can check it with below command

rvm requirements

Just resolve the Dependencies :) It is really a painful procedure! but dependencies may vary from user to user! so you have to solve it on your own!

4) Now lets install Ruby! with below command

rvm install 1.9.3

Now you have installed Ruby! Just tell your machine to use 1.9.3 as default with below command

rvm use 1.9.3 --default

After setting 1.9.3 as default lets get the Ruby gem. RVM now provides a 'rubygems' CLI command which allows you to change the rubygems version for the installed interpreter. In order to install the most recent RubyGems that RVM knows about you can do. Use below command to install

rvm rubygems current

5) Now we have Ruby installed, all we need to install is Rails! and its dependencies through RubyGems

use below command to install Rails

gem install rails

6) Now finally after installing Rails! you can create your very own application skeleton and start the server!

E.g. rails new path/to/your/new/application

cd path/to/your/new/application
rails server

You are now running Ruby on Rails! :)
I hope it helped you :)

New XAMPP security concept [solved]

noreply@blogger.com (Amit Naik) — Tue, 20 Aug 2013 08:16:00 -0700

Hello Everyone,

I have just downloaded the new XAMPP 1.8.0. and got the error at localhost/phpmyadmin

New XAMPP security concept:

Access to the requested object is only available from the local network.

This setting can be configured in the file "httpd-xampp.conf".

If you think this is a server error, please contact the webmaster.

Error 403

localhost

So the solution for this is as follows:

1) Open httpd-xampp.conf which is at /opt/lampp/etc/extra/

2) Find <Directory "/opt/lampp/phpmyadmin">

3) Now just add Require all granted before </Directory>

4) So the code will look like this
    <Directory "/opt/lampp/phpmyadmin">
    AllowOverride AuthConfig Limit
    Order allow,deny
    Allow from all
    Require all granted
   </Directory>
5) Now finally Restart the xampp with this command /opt/lampp/lampp restart

That's it and you are Done!

Found it helpful ? Comment's please :)

Google Chrome's Data Compression Proxy

noreply@blogger.com (Amit Naik) — Thu, 7 Mar 2013 02:35:00 -0800

Hey Guys,

I was just checking the New Google Chrome for Android. It is really a faster android browser.
Infact Google is now comeup with Data Compression Proxy settings.

Now you might think what is Data Compression Proxy?

As per Google this latest Chrome Beta for Android includes an experimental feature to reduce cellular data usage and speed up mobile web browsing,
using proxy servers hosted at Google to optimize website content.

In Google's internal testing, this feature has been shown to reduce data usage by 50% and speed up page load times on cellular networks!

You can also enable this awesome feature.
To enable Data Compression Proxy settings do the following steps in your new Beta Chrome browser.
1) Visit chrome://flags in your browser
2) Select “Enable Data Compression Proxy”
Plain and simple. You are done.

Now after enabling this feature you would be able to reduce overall data usage and speed up the page load times. This feature is performed by Google's massive powerful servers.
Chrome mobile opens a dedicated SPDY connection between your phone and one of the optimization servers running in Google’s datacenters and relays all HTTP requests over this connection.

SPDY for speed

The connection from the mobile device to the proxy runs over SPDY, an optimized protocol for the Web that is supported by Chrome, Firefox and Opera, and is also the basis for the forthcoming HTTP/2.0 standard being developed in the IETF. For more info on SPDY go to open source Chromium Projects SPDY page >> http://www.chromium.org/spdy

Flush drupal cache from code

noreply@blogger.com (Amit Naik) — Tue, 18 Dec 2012 12:24:00 -0800

Hey everyone,

Today I would like to share how to recover a blank drupal website using cache clear. Most of the times we change our websites from one server to another. In drupal when we do that our database tables and files messes the cache settings. But while this is happening in database your websites goes blank or it goes unreachable so in that case you have to run one drupal function which will help you to rebuild the registry, rebuild the menu, rebuild the path.

All you need to do is put the code either on page--front.tpl.php or on page.tpl.php.

<?php

// This will Change query-strings on css/js files to enforce reload for all users.

  _drupal_flush_css_js();


  registry_rebuild();     //To rebuild module data
  drupal_clear_css_cache(); //This will flushes the cached css
  drupal_clear_js_cache(); //This will flushes the cached js

?>

Remember that do not put this code in any if else condition just put it either on page.tpl.php or on front page of your drupal site. And then hit the URL in any browser. Then our code will get executed. Our code would then flush the js and css for all users. Then it would rebuild the registry of all modules. Then it would clear the css cache and then js cache.
So now this would defiantly bring the drupal site back on its feet.

copy image using wget PHP

noreply@blogger.com (Amit Naik) — Sat, 2 Jun 2012 09:37:00 -0700

Hello everyone,
I have just written a PHP script to wget any image.
All you need to do is get the full path of your image e.g.
http://www.google.co.in/images/srpr/logo3w.png is path to google logo.
So now lets wget google's logo.

<?php

$mainimage = "http://www.google.co.in/images/srpr/logo3w.png"; //this would be the path of your live image which you want to download

$thebasename = basename($mainimage); //here we will get logo3w.png i.e. name of file

$filename = explode(".", $thebasename); //explode it with extention
$i=0;
do {
if($i > 0) $filename[0]++;
else $filename[0] = $filename[0].$i;
$i++;
}while(file_exists("tmp_cover/".$filename[0].".".$filename[1])); //typical do while to check for unique file name
$image_dir = "tmp_cover/"; //this will be your directory where you want to save your image
$fresh_file = $filename[0].".".$filename[1]; //this is our renamed file if file already exists
$image_drs = $image_dir.$fresh_file; //i have concatinated the path so it becomes easier to use in wget function
system("wget -q \"$mainimage\" -O $image_drs"); //image uploaded with wget -q

/*
Notes:
1)Please check if your wget version is wget v1.12 and php is php v5.3.1 or greater.
2)Give full permissions to your files (chmod 777 your_dir) or use filezilla client to give full permission to your folder.
3)I have created tmp_cover folder at /opt/lampp/htdocs with 777 permissions.

If you install the new firebug it will allow you to view any webpage in 3d mode. Just right click on webpage and select Inspect Element. After that you will see the new firebug bar at the bottom of your page then click on the 3d button which is at the right bottom. Now you are in 3d mode.
To zoom in or zoom out just use control + mouse scroll or to view from different angle just press control key + left mouse key + move the mouse pointer.

Here are some of the screenshots in 3d mode of my blog.

I think new firebug is kinda cool and really advance. There are lots of new features in it.

Enjoy & be open.

cd Desktop Now you are at the Desktop.

3) Enter this command to install xampp in ubuntu
tar xvfz xampp-linux-1.7.3a.tar.gz -C /opt

4) Now your xampp is installed in opt folder. Now in order to create files and folders in htdocs you need to resolve the htdocs trouble. to give permession to htdocs enter this command sudo chmod 777 -R /opt/lampp/htdocs/

5) Now if everything is fine with no error then it is time to star the xampp in order to start the xampp please enter this command sudo /opt/lampp/lampp start

Hello All,

Are you looking for a good system monitor? Then I think conky is the best option. It is very lightweight application. Conky can display this info either as text, or using simple progress bars and graph widgets, with different fonts and colours. To install conky on ubuntu use this command sudo apt-get install conky

After installing conky you can run it from ubuntu's Run application. Press alt + f2 and then type conky Now you will see the conky application.
