@Afrihost My network has not been working the whole day, how is this resolved?

We’re aware of the current outage and are on top of it. Thank you for your patience while we work to get things back up and running. Check updates here: brnw.ch/21x11HP

top 50 linux commands every devops engineer should know. if you're debugging or securing servers, the terminal is your best friend. here's the ultimate breakdown: 🧵

Learning Python but still not getting interviews? It’s usually because of this. Most beginners learn Python like this ❌ • Finish courses • Memorize syntax • Collect certificates • Build tutorial projects But hiring managers look for something else. This is how Python actually gets you hired 👇 1️⃣ Pick one direction Automation • Backend • Data 2️⃣ Learn the core properly Functions • Lists • Dicts • APIs 3️⃣ Build 4 projects that feel like real work Example: • File automation tool • API data collector • Data report generator • Simple web app 4️⃣ Push everything to GitHub 5️⃣ Write a clean README Explain the problem → solution → output. 6️⃣ Deploy at least one project 7️⃣ Show your progress publicly. Truth most learners realise too late: Companies don’t hire people who “learned Python”. They hire people who can build with Python. Courses teach syntax. Projects prove skills. Reply PYTHON and I’ll share 10 Python projects that actually impress recruiters. 🚀

@afcstuff @SamJDean Jesus has to go we need a top notch no9

🚨 Arsenal will have to sell at least one first-team player this summer. It is understood that there are discussions around who would yield the most lucrative sale & whether more than one player might have to go. Gabriel Martinelli & Ben White are strong candidates. [@SamJDean]

These Linux commands helped me most in last 13 years of IT career Daily stuff: • ps aux | grep {process} - Find that sneaky process • lsof -i :{port} - Who's hogging that port? • df -h - The classic "we're out of space" checker • netstat -tulpn - Network connection detective • kubectl get pods | grep -i error - K8s trouble finder Log related commands: • tail -f /var/log/* - Real-time log watcher • journalctl -fu service-name - SystemD log stalker • grep -r "error" . - The error hunter • zcat access.log.gz | grep "500" - Compressed log ninja • less +F - The better tail command Container cli: • docker ps --format '{{.Names}} {{.Status}}' - Clean status check • docker stats --no-stream - Quick resource check • crictl logs {container} - Raw container stories • docker exec -it - The container backdoor • podman top - Process peek inside containers System Detectives: • htop - System resource storyteller • iostat -xz 1 - Disk performance poet • free -h - Memory mystery solver • vmstat 1 - System vital signs • dmesg -T | tail - Kernel's recent gossip Network stuff: • curl -v - HTTP conversation debugger • dig +short - Quick DNS lookup • ss -tunlp - Socket statistics simplified • iptables -L - Firewall rule reader • traceroute - Path finder File and stuff: • find . -name "*.yaml" -type f - YAML hunter • rsync -avz - Better file copier • tar -xvf - The unzipper (yes, we all google this) • ln -s - Symlink wizard • chmod +x - Make it executable Performance: • strace -p {pid} - System call spy • tcpdump -i any - Network packet sniffer • sar -n DEV 1 - Network stats watch • uptime - Load average at a glance • top -c - Classic process viewer Git Essentials: • git log --oneline - History simplified • git reset --hard HEAD^ - The "oops" eraser • git stash - The work hider • git diff --cached - What's staged? • git blame - The "who did this?" resolver Quick Fixes: • sudo !! - Run last command with sudo • ctrl+r - Command history search • history | grep - Command time machine • alias - Command shortcut maker • watch - Command repeater

Data Engineering Course with 20+ End-to-End Projects! What started as a few courses has now turned into a complete Data Engineering ecosystem. Today, our Data Engineering Course includes 20+ end-to-end projects and covers pretty much everything you need to crack interviews and survive the real job: ✅ Python for Data Engineering ✅ SQL for Data Engineering ✅ Data Warehousing with Snowflake ✅ Apache Spark with Databricks ✅ Apache Airflow ✅ Apache Kafka ✅ Cloud (AWS, GCP, Azure) ✅ End-to-End Real World Projects ✅ Interview Preparation Kit ✅ And a proper “Start Here” roadmap so beginners don’t feel lost Here’s the thing. Most people fail interviews not because they don’t know tools… They fail because they’ve never built real systems end-to-end. So we designed this like an actual Data Engineer’s journey: - Build pipelines - Move data across systems - Orchestrate workflows - Work with warehouses - Handle scale - And explain your design decisions like a pro in interviews And we’re not stopping. We’re continuously adding more projects, more scenarios, more interview-focused content so you’re never underprepared. If your goal in 2026 is to seriously break into Data Engineering or level up, this is exactly what we’re building DataVidhya for. Proud of how far this has come. Even more excited about what’s coming next. 💪
