    geared_pagination

    Paginate Active Record sets at variable speeds

    Most pagination schemes use a fixed page size. Page 1 returns as many elements as page 2. But that’s frequently not the most sensible way to page through a large recordset when you care about serving the initial request as quickly as possible. This is particularly the case when using the pagination scheme in combination with an infinite scrolling UI.

    Geared Pagination allows you to define different ratios. By default, we will return 15 elements on page 1, 30 on page 2, 50 on page 3, and 100 from page 4 and forward. This has proven to be a very sensible set of ratios for much of the Basecamp UIs. But you can of course tweak the ratios, use fewer, or even none at all, if a certain page calls for a fixed-rate scheme.

    On JSON actions that set a page, we’ll also automatically set Link and X-Total-Count headers for APIs to be able to page through a recordset.

    cfn_nag

    Linting tool for CloudFormation templates

    The cfn-nag tool looks for patterns in CloudFormation templates that may indicate insecure infrastructure. Roughly speaking, it will look for:

    • IAM rules that are too permissive (wildcards)
    • Security group rules that are too permissive (wildcards)
    • Access logs that aren’t enabled
    • Encryption that isn’t enabled
    • Password literals

    For more background on the tool, please see this post at Stelligent’s blog:
