Happy Tuesday!

Last week, we celebrated the end of Ramadan, which is the most significant month in the Islamic calendar. The 20th of April marked the end of Ramadan and the 21st was observed as a holiday in Muslim countries.

During this month, millions of Muslims worldwide fast by not eating and drinking until dusk. The fast intends to cultivate a deeper sense of compassion and empathy for those less fortunate.

We celebrate Ramadan and greet our readers who practice this sacred tradition.

As we reflect on the teachings of Ramadan, let us explore the rich world of tech and see the hottest developments.
