It presents a scene of [CITY] in 3D miniature caricature style, with a clear 45° isometric perspective from above, that highlights its most iconic monuments and architectural elements. Use soft, refined textures with realistic PBR materials, along with soft, realistic lighting and shadows.
Integrate current weather conditions directly into the city surroundings to create an immersive atmosphere.
Use a clean, minimalist composition with a solid, soft color background.
In the upper central part, place the title "[CITY]" in large and bold text, a prominent meteorological icon below this, followed by the date (small text) and temperature (medium text). The entire text should be centered with a constant spacing and can subtly overlap with the top of the buildings.

🌐 Networking Basics Every IT Professional Should Know
If you're starting your journey in Networking, CCNA, or Cybersecurity, understanding these core concepts is essential. This quick guide covers some of the most important building blocks of modern networks.
📌 Key Networking Concepts
🔹 Network – Connects multiple devices to share data and resources.
Types include LAN, WAN, and MAN.
🔹 Switches – Connect devices within a Local Area Network (LAN) and forward frames based on MAC addresses.
🔹 Router – Directs data packets between different networks using routing protocols.
🔹 VLAN (Virtual LAN) – Segments a network into multiple logical networks for better performance and security.
🔹 Trunking – Allows multiple VLANs to travel across a single link using 802.1Q tagging.
🔹 EtherChannel – Combines multiple physical links into one logical link to increase bandwidth and redundancy.
🔹 STP (Spanning Tree Protocol) – Prevents network loops in Layer 2 switching environments.
🔹 ACL (Access Control List) – Filters network traffic to control which packets are allowed or denied.
💡 Pro Tip:
Mastering these fundamentals makes it much easier to understand advanced networking, cloud infrastructure, and network security.

Recent data from INSS highlight Iran's response through ballistic missile and drone strikes across several countries in the Middle East, following the joint U.S.-Israel air attacks.
The United Arab Emirates appears as the most targeted location, with an estimated 863 missiles and drones, followed by Kuwait with 562. Qatar recorded around 162 incidents, Bahrain 129, and Israel 113, while Jordan reported 49. Smaller figures were registered in Cyprus (5), Oman (2), and Saudi Arabia (2).
The geographic pattern is closely tied to regional military infrastructure. Countries such as Bahrain, Qatar, Kuwait, and the UAE host major U.S. and allied military bases, making them central nodes in the region's defense network. Many of the incoming missiles and drones were intercepted by air defense systems, yet the scale of launches highlights the growing role of high-volume drone and missile warfare in modern conflicts.

🚨 Iranian fingerprint inside American networks... And hacks that stayed hidden for weeks
Broadcom researchers have uncovered an advanced cyber-spying campaign carried out by the Iran-linked MuddyWater group, after observing its presence within the networks of several companies in the United States without drawing attention for some time.
Technical analysis has shown that attackers used a backdoor based on the Deno environment to run remote commands inside the infected systems, a style that provides high concealment because this environment is less used in traditional malware. Attackers also attempted to transfer data off targeted networks via Rclone tool to cloud storage services, in an attempt to extract sensitive information without triggering surveillance systems.
The activity reflects the pattern of long-term cyber espionage operations dependent on country-linked threat groups, where access within targeted networks is quietly maintained before carrying out information collection or data leak operations. #CyberSecurity#ThreatIntel#APT#Iran#Malware#CyberEspionage#InfoSec#hackers

GPT-5.4 was released on March 5, 2026 with a massive 1M-token context window, allowing it to analyze entire codebases at once and reduce errors in agentic tasks by up to 40%.
It can also create complex apps like 3D games and simulators in one shot. The model includes native computer-use features for screenshot-based UI automation.

1. Set session expiration (JWT max 7 days + refresh rotation)
2. Never use AI-built auth. Use Clerk, Supabase Auth, or Auth0
3. Never paste API keys into AI chats. Use process.env
4. .gitignore is your first file in every project, not the last
5. Rotate secrets every 90 days minimum
6. Verify every package the AI suggests actually exists before installing
7. Always ask for newer, more secure package versions
8. Run npm audit fix right after building
9. Sanitize every input. Use parameterized queries always
10. Enable Row-Level Security from day one
11. Remove all console.log statements before shipping
12. CORS should only allow your production domain. Never wildcard
13. Validate all redirect URLs against an allow-list
14. Apply auth + rate limits to every endpoint, including mobile APIs
15. Rate limit everything from day one. 100 req/hour per IP is a start
16. Password reset routes get their own strict limit (3 per email/hour)
17. Cap AI API costs in your dashboard AND in your code
18. Add DDoS protection via Cloudflare or Vercel edge config
19. Lock down storage buckets. Users should only access their own files
20. Limit upload sizes and validate file type by signature, not extension
21. Verify webhook signatures before processing any payment data
22. Use Resend or SendGrid with proper SPF/DKIM records
23. Check permissions server-side. UI-level checks are not security
24. Ask the AI to act as a security engineer and review your code
25. Ask the AI to try and hack your app. It will find things you won't
26. Log critical actions: deletions, role changes, payments, exports
27. Build a real account deletion flow. GDPR fines are not fun
28. Automate backups and test restoration. An untested backup is nothing
29. Keep test and production environments completely separate
30. Never let test webhooks touch real systems

JUST IN: Iran allegedly painted fake plane on concrete. U.S. thought they were real.
They spent over $5 million to bomb them. Then realized they’d been deceived
