• node.js: encrypting data that needs to be decrypted?

  - by fancy

  We are using bcrypt for passwords and data that never needs to be decrypted. What should do to protect other user information that does. For this example lets say that we didn't want a users real name to be in plain text in case someone was to obtain the db. This is somewhat sensitive data but also needs to be called from time to time and displayed in plain text. Is there a simple way to do this?

• How should I grab pairs from a list in python?

  - by tomaski

  Say I have a list that looks like this: ['item1', 'item2', 'item3', 'item4', 'item5', 'item6', 'item7', 'item8', 'item9', 'item10'] Using Python, how would I grab pairs from it, where each item is included in a pair with both the item before and after it? ['item1', 'item2'] ['item2', 'item3'] ['item3', 'item4'] ['item4', 'item5'] ['item5', 'item6'] ['item6', 'item7'] ['item7', 'item8'] ['item8', 'item9'] ['item9', 'item10'] Seems like something i could hack together, but I'm wondering if someone has an elegant solution they've used before?

• DDD and avoiding CRUD

  - by g_b

  It seems that on most articles I read, CRUD is to be avoided in DDD as we are dealing with modeling business process and not data. However, I find it hard to see not to have CRUD operations on certain entities. For example, in a school grading system, before teachers can grade students, a SchoolYear has to be present or perhaps a GradingPeriod. I can't see how we can manage GradingPeriods without CRUD. Could someone enlighten me on this?
