Golden path (in software)

What is golden path in software?

A golden path in software is a standardized, opinionated, and supported set of tools, processes, and best practices for common tasks, such as building and deploying applications.

Provides developers with a streamlined and efficient "approved way" of working, reducing complexity, decision fatigue, and technical debt.

By offering a well-defined and templated route, golden paths allow developers to focus on delivering business value rather than reinventing infrastructure and tooling, ultimately accelerating delivery velocity and improving consistency across an organization.

Golden path in platform engineering:

Instead of a new team having to figure out logging, monitoring, and CI/CD from scratch, a Spring Boot golden path would provide a ready-to-use template with pre-configured logging, monitoring, and deployment pipelines, allowing the team to focus on their application code.  

Extending battery life in Linux

Extending battery life in Linux:

So, you want to extend your laptop battery life as much as possible.
One way is to avoid 100% charging of the battery.

We can easily configure this in Linux(my default OS) using tlp.

In case of RedHat distributions(Fedora, CentOS, RHEL):
sudo dnf install tlp tlp-rdw

Install tlp package:  (for Debian/Ubuntu distributions)
sudo apt install tlp tlp-rdw)

Enable and start it:
sudo systemctl enable tlp --now

Edit the config:
sudo vi /etc/tlp.conf

Find and set these values (ensure it is uncommented):
START_CHARGE_THRESH_BAT0=75
STOP_CHARGE_THRESH_BAT0=80

(This means charging will stop at 80%, and only resume if it drops below 75%.)

Restart tlp
sudo systemctl restart tlp

Verify the new values:
sudo tlp-stat -b
(This should display updated values).

Now, you can check how the discharge/recharge changes in your laptop battery.

Use Settings -> Power and enable % value for battery to check the values.

Google doc's tabs

 

I've just come across this new feature from google docs's tabs. 
This is something similar to tabs we use in browser.

 So we create a document which is aligned towards single topic.
In the same document we can have sub-topics under the single topic.
We can also have sub-sub topic inside :) 

--

Tabs in Google Docs let you create sections within a single document, similar to tabs in a web browser or spreadsheet. Each tab can contain separate content, allowing you to organize related information without switching between different Docs files.

Think of it like this:

• Instead of having 5 separate Docs files for different aspects of a project, you can have 1 Google Doc with 5 tabs, each dedicated to a topic.

   

   Example:

  Let's say we have a AI project with main document name as "AI Assistant for Customer Support"



  We can have tabs as below:
  

  Tab Name	What to Include
  1. Problem Statement	Define the problem you're solving, pain points, target users, and project goals.
  2. Data Collection & Cleaning	Sources of data (chat logs, support tickets), privacy considerations, preprocessing steps.
  3. Model Selection & Training	ML/DL models considered (e.g., BERT, LLMs, custom models), training setups, experiments.
  4. Evaluation & Metrics	Accuracy, F1 score, confusion matrix, user feedback — how you’ll judge model quality.
  5. Deployment Plan	Architecture, inference setup (e.g., REST API), infrastructure (AWS/GCP), latency goals.
  6. UI/UX Design	Interface mockups, chatbot UX, conversation flows.
  7. Risks & Ethical Concerns	Bias, hallucinations, GDPR issues, response safety.
  8. Timeline & Milestones	Sprint plans, deadlines, deliverables.
  9. Team & Roles	Who’s doing what: ML engineer, designer, backend, QA, PM, etc.
  10. References & Tools	Research papers, tech stack, tools used (e.g., Hugging Face, PyTorch, LangChain).

  
  

  This is awesome way to have a organized info.  Thanks Google.
  
  Thanks to ChatGPT for fetching an example.
  

Determine your graphical platform - X11/wayland

 

-- 

Open a terminal and run the command echo $XDG_SESSION_TYPE.

The output reveals either of these values and thereby the display protocol used: "x11" OR "wayland".

Most modern systems make use of wayland.
--

Wayland:
A newer, more secure, and potentially more performant display protocol, especially for modern graphics hardware.

X11:
The traditional display server protocol used by many Linux systems, including Ubuntu.
