বর্ধমানের আউসগ্রামের দরিয়াপুর - ডোকরা শিল্পগ্রাম

বর্ধমানের রাজা কীর্তিচাঁদের বানানো জলটুঙ্গি ঘুরতে গিয়ে খোঁজ পাই বাংলার এই প্রাচীন শিল্পকলার। যদিও ডোকরার ইতিহাস ৪০০০-৪৫০০ বছরের পুরোনো এবং সেই অর্থে ডোকরা খাঁটি বাংলার শিল্পকলা নয়। জলটুঙ্গি থেকে মাত্র ৫ কিলোমিটার দূরে দরিয়াপুর। 


ডোকরা হল ভারতবর্ষের অন্যতম পুরোনো আদিবাসী শিল্পকলা যার ইতিহাস প্রায় ৪৫০০ বছরের। মনে করা হয় ‘হারানো মোম ঢালাই’ পদ্ধতির (Lost or vanishing wax casting method) এই শিল্পকর্মের বিকাশ ভারতে প্রথম ঘটেছিল মধ্যপ্রদেশের বস্তার অঞ্চলে ডোকরা-ডামার উপজাতি মানুষদের হাতে। তাঁদের নামেই এই শিল্পের নাম 'ডোকরা'। কথিত আছে প্রায় ৩০০০ বছর আগে বস্তারের রাজা তাঁর রাণীর জন্য ডোকরার গয়না তৈরি করিয়েছিলেন। তবে সিন্ধু সভ্যতার শহর মহেঞ্জদোড়োতে প্রাপ্ত "ড্যান্সিং গার্ল" বা "নৃত্যরত নারী মূর্তি" হল ডোকরা শিল্পের এক প্রাচীন নিদর্শন। কাজেই এই শিল্পের মূলধারা কোথায় সে বিষয়ে যথেষ্ট তর্কবিতর্ক আছে।

Tareq Amin Lands on Aramco Digital to Continue His Dream for Open RAN


Back in 2020, O-RAN was just more than a concept, I covered its advantages and how Indian operators could be beneficial by embracing it. The post also covers the importance of 5Gi or Desi 5G for the operators as they were ditching Chinese vendors. This move to ditch Chinese vendors was also appreciated by American politicians. 

However more than 1 year after 5G launch in the country, none of the operators deployed Open RAN ecosystem. Though all three - Jio, Airtel and Vi had explored O-RAN based networks before the 5G launch.

5G-NTN : New Dimension of Satellite Communications

Starlink's satellites 

5G space is getting excited by another new domain - that's 5G NTN (Non Terrestrial Network). The basic idea of 5G NTN is to deliver 5G/NR service via satellite or other airborne platform (like Google Balloons or Project Loon). 

Earlier I wrote regarding the competition between 5G and satellite broadband will be inevitable. But they can synergize to create an efficient and much-desired fusion of terrestrial and non-terrestrial networks to bring internet connectivity in the country as well as globally. 

5G-NR is known for the enhanced speed, higher network capacity, lower latency, improved reliability and coverage. With 5G-NR there are new and innovative uses with IoT - like smart cities,  remote industrial automation, artificial intelligence and augmented reality, revolutionizing industries, and empowering novel applications.

Mid 2023: Tablet Buying Guide

When smartphones started coming to India, big screen smartphones were something called luxury. If you can remember, in 2010 Notion Ink Adam was a great tablet by Indian company. But it never got the commercial success, like the applaud they get during initial launch announcement. It got delayed several times, testing the patience of the buyers and the tech community. Frankly speaking, tablet market is always a risk for the OEMs, except Apple - the makers of iPads. 

It's been just middle of 2023, and we have 2 gorgeous Android tablets in Indian market - One Plus Pad and Xiaomi Pad 6. Both are affordable and superb looking devices with several accessories to pump them out.
