From C# 1.0 to C# 15. Everything you need in one place 👇

Most .NET developers miss the latest features and are writing code like using C# 6 or 8.

ההשקעה הכי טובה בפיתוח היא עדיין מערכת CI מהירה עם בדיקות מקיפות (לפעמיים זה מתנגש).

העובדה שטיל נחת על חוות שרתים של aws ורק availability zone אחד נפגע הוא אות מופת לתכנון התשתיות של אמזון.

הפרדה גאוגרפית משמעותית, תשתיות חשמל, אינטרנט, וקירור נפרדות לחלוטין.

יש למכור שרתים, ויש למכור את מה שaws מוכרת.
