عصر Portable .Net

The new .NET framework is modern, lean, modular and open source. No longer is .NET a system-wide installation – it is merely a folder. Instead of a huge underlying framework, you only pick and choose the pieces of the .NET framework that you need in your apps. And more importantly, you can package the required components of the .NET framework right alongside your app. We’re entering an age of app-runtime silos and ultimate portability.

چرا SQL در حال شکست NoSQL است؟

SQL is back. Not just because writing glue code to kludge together NoSQL tools is annoying. Not just because retraining workforces to learn a myriad of new languages is hard. Not just because standards can be a good thing.

But also because the world is filled with data. It surrounds us, binds us. At first, we relied on our human senses and sensory nervous systems to process it. Now our software and hardware systems are also getting smart enough to help us. And as we collect more and more data to make better sense of our world, the complexity of our systems to store, process, analyze, and visualize that data will only continue to grow as well.

تمرین‌های SQL نویسی

The lost art of writing SQL queries
I noticed that most (junior) developers no longer are able to write anything but the most trivial SQL queries.  Time to fix that!
