Changing the curriculum and content: There is an opportunity cost associated with the decision we make

Are CBSE and other boards designing the syllabus and curriculum by the sweat of their brow by attending the feedbacks, research, and evidence? Our education system should remain brother's keeper to all children of the worlds second populated country.  Why an unstructured syllabus with low-quality and pedagogically unsound content be continued even after everyone knows emperor is naked.

There is a trade-off,  between adapting to the newly changed content and enhancing the quality of content.  But it could have been done slowly.

Aadhaar: It's time to encrypt all biometric data with password

All biometric data should be encrypted. During authentication, the user needs to provide both aadhar number and password. So only the user can decrypt and access the biometric data. Biometrics of the little finger can be kept in the unencrypted form, to remove duplicates. In case you forget the password: One has to submit the aadhaar number and little finger biometrics to obtain another. The ciphertext of aadhaar number should be replaced with new ciphertext (obtained from new password) In case you lost both (Password and Aadhaar Number): The person must come under scrutiny and old aadhaar number should be removed by using his/her little finger, and new aadhaar number can be given. To change the password: Enter the old password and aadhaar number, match the ciphertext with your fingerprint and then replace the ciphertext with new password. All the steps should be done in aadhaar center. The python code: from Crypto.Cipher import AES obj = AES.new('Aadhaar No:1234567891012', AES
