mkisofs

Muhammad Jazman — Sat, 25 Jul 2026 17:38:06 +0000

create ISO for this directory

alias isonodos='mkisofs -J -R -l -joliet-long -o'

how to use it ...
isonodos ../filename.iso .
it will create a ISO file from this directory ( see the trailing . )

Why ISO file?

if you use windows, that buggy resource intensive telemetry and file scanner and antivirus or antiprivacy or whatever, i'm not sure, will try to extract zip file or some shi77y files from your backup... and seems the ISO is somehow the remedy. since it has no compression, just raw copy, the shitty spywareOS will not cost your box too much. you can mount it (so it will browsable) but still easy to backup, since it is a single .ISO file.

alias cd..

alias cd..='cd ..'
alias cd...='cd ../..'
alias dir='ls -al;echo;echo;echo;du -h -d 1'

alias 7z

Muhammad Jazman — Sat, 25 Jul 2026 17:24:24 +0000

max compression for 7z

alias 7z_='7z a -t7z -m0=lzma -mx=9 -mfb=64 -md=32m -ms=on'

split 50 megabyte, telegram limit sending file

alias 7z_50m='7z a -t7z -m0=lzma -mx=9 -mfb=64 -md=32m -ms=on -v50000000b'

add a password 123 to the 7z

alias 7z_p='7z a -t7z -m0=lzma -mx=9 -mfb=64 -md=32m -ms=on -p123 -mhe'

add a password 123 and split 50 megabyte

alias 7z_50m_p123='7z a -t7z -m0=lzma -mx=9 -mfb=64 -md=32m -ms=on -v50000000b -p123 -mhe'

ls -al with du

Muhammad Jazman — Sat, 25 Jul 2026 17:15:02 +0000

alias dir='ls -al;echo;echo;echo;du -h -d 1'

if you've been introduced with DOS 30+years ago, and just learn linux for 25 years, as a n00b like me, you'll gonna love to type dir instead of ls -al in your linux terminal. this alias is handy, showing how much this directory currently occupy my cheap small SSD, and also for each subdir.

Github Profile Pimp Prompt

Muhammad Jazman — Fri, 24 Jul 2026 02:36:02 +0000

ChatGPT #prompt to fix #Github profile

Prompt 1 — Deep GitHub Profile Audit (Better Version)

Goal: Find weaknesses from recruiter perspective, not just grammar/design.

Act as a senior technical recruiter and engineering manager who reviews hundreds of GitHub profiles every month.

Audit my GitHub profile as if I am applying for a [backend/frontend/full-stack/devops/data engineer] position.

Here is my GitHub profile:
[PASTE PROFILE README]

Here are my top repositories:
[PASTE REPO LINKS]

Analyze:

1. First impression:
- What would a recruiter think in the first 30 seconds?
- Does my profile immediately communicate my role and expertise?
- Do I look like a beginner, intermediate, or professional developer? Explain why.

2. Credibility analysis:
- Are my projects strong enough to prove my skills?
- Which projects look impressive?
- Which projects look like tutorials or copied work?
- What evidence of real engineering ability is missing?

3. Technical evaluation:
Review:
- Code quality
- Repository structure
- Documentation
- Commit history
- Testing practices
- CI/CD usage
- Deployment evidence
- Architecture explanation

4. Recruiter concerns:
List anything that could reduce my hiring chances:
- unclear skills
- weak descriptions
- missing technologies
- poor README
- unfinished projects
- outdated repositories

5. Give me a prioritized improvement roadmap:
Rank improvements:
Priority 1 = must fix before applying
Priority 2 = improves credibility
Priority 3 = optional improvements

Be brutally honest. Do not give generic advice.

Prompt 2 — Professional GitHub Rebranding (Better Version)

The original prompt only rewrites text. A recruiter needs a personal brand strategy.

Based on your audit, redesign my GitHub profile as a professional developer portfolio.

My target:
Role:
[Backend Engineer / Full Stack Developer / DevOps Engineer]

Experience level:
[Student / Junior / Mid-level]

Target opportunities:
[Remote jobs / Freelance / Startup / Enterprise]

My technical stack:
[Java, Spring Boot, React, Docker, AWS, etc.]

Create:

## 1. GitHub Bio
Write:
- 3 options
- Maximum 150 characters
- Professional but human
- Avoid buzzwords

## 2. Profile README

Structure:

# Introduction
Who I am and what I build.

# Tech Stack
Organize technologies professionally.

# Featured Projects
For each project include:
- Problem solved
- Technology used
- Architecture overview
- Key technical challenges
- Result/impact

# Current Focus
What I am learning/building.

# Engineering Philosophy
Short statement about how I approach development.

# Contact
Professional links.

Make it attractive for recruiters but avoid exaggerated claims.
Only mention skills supported by evidence from my repositories.

Prompt 3 — GitHub Portfolio Design Optimization (Better Version)

The original focuses too much on badges and widgets. Recruiters care more about information hierarchy.

Use:

Act as a GitHub portfolio designer for professional software engineers.

Improve my GitHub profile README visually and structurally.

My goal:
Make recruiters understand my value within 30 seconds.

Suggest:

1. Layout improvements:
- Section order
- Information hierarchy
- What should appear above the fold

2. Visual improvements:
Recommend:
- Badges
- Tech stack icons
- Project cards
- Contribution graphs
- GitHub statistics
- Animations (only if professional)

For every recommendation provide:
- Why it helps recruiters
- Exact implementation steps
- Markdown/code snippet

3. Featured repository strategy:
Tell me:
- Which repositories should be pinned
- Which should be archived/private
- How many projects are ideal

4. Professional standards:
Compare my profile with profiles of strong engineers.

Avoid making it look like a flashy beginner portfolio.
Prioritize credibility and technical professionalism.

Prompt 4 — Transform My Repositories Into Recruiter-Level Projects

Because many GitHub profiles fail because the projects themselves are weak.

Analyze my GitHub repositories and choose the 5 strongest projects for my portfolio.

For each project:

1. Evaluate:
- Technical complexity
- Real-world usefulness
- Recruiter appeal
- Engineering maturity

2. Suggest improvements:
- Features to add
- Architecture improvements
- Testing improvements
- Documentation improvements
- Deployment improvements

3. Rewrite the repository README:
Include:
- Project overview
- Architecture diagram
- Features
- Tech stack
- Installation guide
- API documentation
- Screenshots
- Future improvements

4. Tell me what project would make the strongest portfolio centerpiece.

My Recommended Workflow

Don't start by rewriting README.

Do this order:

Step 1
Audit profile
↓
Step 2
Choose strongest projects
↓
Step 3
Improve project quality
↓
Step 4
Rewrite README
↓
Step 5
Optimize visual appearance
↓
Step 6
Create professional LinkedIn + CV alignment

A beautiful GitHub profile with weak projects still looks weak.

A simple GitHub profile with 3 excellent, documented, deployed projects can beat a profile full of badges and animations.

For a junior → mid-level developer, I would prioritize:

⭐ 3–5 strong pinned repositories
📄 Excellent README per project
🚀 Live deployment/demo
🧪 Testing + CI/CD evidence
🏗️ Architecture diagrams
Then visual polish

This version will produce a much stronger recruiter-facing GitHub transformation.
