[Puneet Patwari @system_monarch]

I've been a backend Engineer for 12+ years. Today, I'm a Principal Engineer at Atlassian.

I've designed systems that handle millions of requests. Sat on both sides of system design interviews.

Reviewed more architecture docs than I can count.

Starting today, I'm breaking down the fundamentals of scaling for the next 25 days.

If you're learning system design bookmark this thread, you're going to get a lot of learning from this.

[Tech with Mak @techNmak]

These engineering blogs have leveled up my tech skills more than any bootcamp, course, or conference.

Here are the ones worth bookmarking:

[Suraj Sharma @suraj_sharma14]

If you're serious about becoming a Senior Backend Engineer in 2026, master this progression:

Level 1: Postman / Bruno
Test APIs properly before your users become your QA team. Contracts matter from day one.

Level 2: Redis
Speed is easy. Cache invalidation is the real challenge. Learn to weigh trade-offs over cleverness.

Level 3: PostgreSQL
Data modeling, indexing, transactions the foundation of real backend thinking. Schema design is system design.

Level 4: Kafka
Async systems are powerful, but retries, ordering, and idempotency separate juniors from seniors. Failure is a feature you design for.

Level 5: Docker
"Works on my machine" should have ended in your junior years. Consistency beats convenience every time.

Level 6: OpenTelemetry
Trace requests across services and distributed systems finally make sense end-to-end. Observability isn't optional it's essential.

Level 7: Grafana
Dashboards that show latency, errors, and throughput not just pretty graphs. If you can't measure it, you can't improve it.

Level 8: Prometheus
Metrics that force you to think in SLOs and system health, not just features. Reliability outpaces feature velocity in the long run.

Level 9: k6
Load test your "scalable" backend. Watch it break. Then fix it. Scale is a verb, not an adjective.

Level 10: Terraform
Senior engineers don't just write code. They own the infrastructure it runs on. Infrastructure is code. Ownership is culture.

The pattern:
• Foundation: Postman/Bruno, PostgreSQL, Redis
• Resilience: Kafka, Docker, k6
• Observability: OpenTelemetry, Grafana, Prometheus
• Ownership: Terraform

Master one layer before rushing the next.

(save it)

@Big14teru Happy birthday boss. More wins to you

[Atenov int. @Atenov_D]

A Chinese developer built a free money printer. Literally named it MoneyPrinterTurbo. 13,000+ stars on GitHub.

You type a topic or keyword. It generates the script, finds HD copyright-free footage, adds subtitles, background music, and voiceover - then outputs a finished short video.

This is the exact pipeline TikTok Shop and YouTube faceless channel creators use to scale to $6,000-10,000/month. The difference: they paid for tools. This is free.

> What's inside:

Script generation via Claude, DeepSeek, Gemini, GPT, or any LLM you already have access to.

Batch video generation - create multiple versions at once, pick the best one. 9:16 vertical for TikTok and Reels, 16:9 horizontal for YouTube.

Voice synthesis with real-time preview.

Custom subtitles - font, size, color, position, outline. Background music from built-in library or your own files.

> Runs locally on your machine. Web UI and API both included. Docker supported. Google Colab supported if you don't want to install anything.

No subscriptions. No watermarks. No usage limits.

The repo is actively maintained - last commit was 44 minutes ago.

- Database and Caching Fundamentals
- Distributed Systems, Microservies and Architectural Patterns
- System Design Tradeoffs
- 40+ interview problems categorized by difficulty level

Check it out here: https://t.co/pkVpi6LxSV

If you find the repo valuable, consider giving it a ⭐️ and share with others.

Thanks to everyone who has starred or forked the repository!

No course will get you a cybersecurity job. Labs will. Here are the 10 you need to practice right now.

1. TryHackMe SOC Level 1 Path: the single best starting point for anyone who wants to work in a SOC. Covers log analysis, SIEM tools, threat detection, and incident response in a fully guided, beginner-friendly format. https://t.co/jqYUL166VU

2. HackTheBox Starting Point: step-by-step guided machines that take you from zero to your first real exploitation. Once you finish Starting Point, move to the easy machines and build from there. https://t.co/xpC1bDl0TO

3. PortSwigger Web Security Academy: the best free resource for learning web application security. Every OWASP Top 10 vulnerability covered with real labs you actually hack, not just read about. Free. https://t.co/25VIlgwBL0

4. Blue Team Labs Online: defensive security labs focused on forensics, threat hunting, SIEM analysis, and incident response. Built specifically for people who want to work on the blue team side. https://t.co/FAhx2Tz78f

5. OWASP WebGoat: a deliberately insecure web application you run locally and attack. One of the best ways to understand how web vulnerabilities actually work from the inside. https://t.co/QaYoLz19dJ

6. VulnHub: free downloadable vulnerable virtual machines you spin up in VirtualBox and practice on locally. No internet required, no subscription, just download and hack. https://t.co/P4YkpsowR2

7. PicoCTF: a free beginner CTF platform built by Carnegie Mellon University. Covers web exploitation, forensics, cryptography, reverse engineering, and binary exploitation through hundreds of challenges. https://t.co/s1wJUOeiWJ

8. OverTheWire Bandit: a wargame that teaches Linux fundamentals, SSH, file permissions, and basic exploitation through progressive challenges. If your Linux skills are weak, start here before anything else. https://t.co/YhlcsO0wNm

9. Immersive Labs: used by enterprise security teams globally for hands-on skills development. Has a free tier with labs covering SOC, malware analysis, cloud security, and threat intelligence. https://t.co/4LAjDmwebr

10.Cyberdefenders: blue team focused labs built around real-world attack scenarios with PCAP files, malware samples, and memory forensics. The closest thing to working a real incident without being on the clock. https://t.co/9PMRoFRF8D

The gap between people who get hired and people who keep applying is not certificates. It is lab hours. Put in the reps.

Save this and share it with someone trying to break into cybersecurity.

Repost for others to see.

[Ihtesham Ali @ihtesham2005]

Two Bulgarian friends killed the entire streaming industry.

It's called Stremio + Torrentio. You get 4K content from Netflix, Disney+, Hulu, and HBO Max combined for free.

Here's how it works.

Stremio is the player. Clean interface. Works on Windows, macOS, Linux, Android, iOS, and TV. You install it once and it looks like any other streaming app.

Torrentio is the addon. You add it to Stremio in one click. It scrapes content from every major torrent provider on the internet simultaneously and delivers the best available stream directly to your player. 720p, 1080p, 4K. You pick the quality. It finds the link.

→ No account required
→ No subscription
→ Works on every device
→ 4K and HDR supported
→ Subtitles built in

Netflix cannot shut this down. There is no central server to seize. No company to pressure. No domain to kill. It runs on your device and pulls from the open internet.

The entire streaming industry is built on one assumption. That you will keep paying $70/month rather than spend 5 minutes on GitHub.

That assumption just died in Sofia, Bulgaria.

MIT License. 100% Opensource.

I’ve spent the past couple of weeks building Looters: a public archive of Nigerian political corruption since the 1990s.

Governors, ministers, shell companies, Swiss accounts, the Jersey trusts, — one searchable graph.

Here are 10 GitHub repos that quietly print money while you sleep.

1. Cal. com
Open-source Calendly. Fork it, white-label it, sell to dentists and lawyers for $200/month. The founders hit $5M ARR in 3 years doing exactly this.
Repo → https://t.co/haz8ihRsHm

2. Plausible Analytics

Repo → https://t.co/Z1MdZ5Zapg

4. n8n
Open-source Zapier. Sell automation services for $500-$2,000 per setup. n8n raised $14M because the agency model behind it works.
Repo → https://t.co/hdycABGGc1

5. Supabase

Repo → https://t.co/N5Fk22qraT

9. Listmonk
Open-source Mailchimp. Send unlimited emails for the cost of an AWS bill. Resell to agencies at 10x markup.
Repo → https://t.co/NS6Uukcklw

10. Penpot
Open-source Figma. Sell self-hosted design tools to agencies who refuse to upload client files to the cloud.
Repo → https://t.co/Lx1CYUP4p4

The difference between developers who build features and developers who build businesses is one decision.

Pick one of these. Fork it this weekend. Ship it next week.

The founders behind these repos already proved the model.

Save this. Share it with the developer in your life who deserves to break free.

100% free. 100% open source.

@Pelz_Dev @sherlockdefi Congratulations, this is massive!

[Smart👨‍💻 | Software Engineer @smartnakamoura]

APIs every Nigerian fintech developer should know exists:
- NIBSS instant payment API (real-time interbank transfers)
- Paystack Transfer API (bulk disbursements)
- Flutterwave BVN verification
- Mono for bank account data and statements
- Okra for transaction history and identity
- Smile Identity for KYC and document verification
- Remita for government payment collections
- VFD for virtual account issuance

Most devs building fintech products in Nigeria are reinventing wheels that already exist.

Save this.
