"If you don't know where you are going, any road will do" "If you don't know where you are, a map won't help".. #tech #Software #anwendungentwickoung
My Professor just said this in class and it sticked "every backend system is fundamentally about data transformation and movement".
I find Git commands interesting! To initialize a new repo, you just type git init. And to create and switch to a new branch? git checkout -b <name>! Isn't that cool? #Git #Coding
`touch file` or `mkdir -p src/{a,b}` fails in Windows CMD/PowerShell but works in Git Bash, macOS, and Linux. Why? Unix tools. Git Bash just brings them to Windows. Use it for a smoother dev workflow. #Git #DevTips #Windows
The Madness 💆💆
This is really interesting. Candy crush used the Freemium model to pivot to 1B+ in valuation..
5 ways to monetize your side project: - Freemium: Free core, pay for power features. - One-time purchase: Buy once, own forever. - Subscription (SaaS): Recurring fee for ongoing value. - Ads/Sponsorships: Monetize audience attention. - Paid add-ons/Marketplace: Sell extensions…

The most expensive line of code is the one you'll have to maintain for 5 years. Write for your future self. #SoftwareEngineering
Ever lost your command when working in a terminal ? Press Ctrl + R to search your command history. A productivity game-changer. #DevTips
When building with python use a virtual environment (venv). It prevents package conflicts and keeps your projects isolated and clean. #tech#python
Use git rebase -i HEAD~N to clean up your last N commits before pushing. It keeps your commit history tidy. #GitTips
Normalization vs. Denormalization? Normalize for data integrity, denormalize for read performance. It's always a trade-off. #Database
Want cleaner code? Refactor functions over 15 lines. Single-purpose functions are easier to read, test, and maintain. #CodeQuality
No one tells you how exhausting it is to write the perfect regex pattern.
My regex for finding my next follower: /^([a-z0-9]+\.(tech|dev)|bugbounty|hackerone|tryhackme|hackthebox)$/ If you're building, securing, or breaking things, let's connect
Infrastructure as Code isn't complicated—it's just writing down what you'd do manually so you never forget a step.
Had my first SQL 'aha!' moment today! Figured out how to use JOIN statements to combine data from multiple tables. It felt like unlocking a superpower. Now I understand why SQL is so powerful for data analysis. #SQLqueries #learning #data #programmerlife
What's a CVSS score? It's a universal standard for assessing the severity of a software vulnerability. Scores from 0-10 help security teams and developers prioritize which bugs to fix first. It's like a threat-level indicator for code.
Just automated a tedious task! Wrote a Python script that analyzes HTML files, extracts CVSS scores, and groups them by responsible admin. The best part? It emails the relevant files directly to each admin. So much time saved! #automation #Python #scripting #sysadmin #infosec
Learned about LDAP (Lightweight Directory Access Protocol) . It's like a phonebook for your network, used to find and manage resources, like users, devices, and other network services. Many organizations use it for centralized authentication. #networking #sysadmin #LDAP #tech
