  private $milk;
  }

• class Cow {
  public $milk;
  }

    $daisy = new Cow();
    $daisy->milk = "creamy";

Description: as discussed in Feb 16 TOC meeting (TBD toc issue), take a look at incubated/graduated projects and check to what degree projects have documented policies for users to report security vulnerabilities and how known vulnerabilities are communicated

Impact: support TOC in evaluating proposed criteria to validate requirement which is already part of CII badge requirement

Scope: tak

Now that we've moved PrairieLib back into the monorepo, we should use direct requires. That is, everywhere that we do this: https://github.com/PrairieLearn/PrairieLearn/blob/89d265461da214d773b722b5e0465e00396f52b1/lib/question.js#L20 we should change it to:

const sqldb = require('../prairielib/sql-db');

and similarly for any require with @prairielib.

This would be a nice function to have, instead of having to rewrite it each time I write a question that needs it.

u is a scalar multiple of v if there is a scalar k such that u = k*v. You could find this k by computing the ratio u_i / v_i for each non-zero component i, then check that the ratios are all equal. This should work similarly to isclose, allowing given relative and a

A student should be able to get an anonymised link of their submission so that they could share it (e.g. on social network). The view would be a readonly view with the feedback of the submission still visible. The link should only contain the submission id.
There should be an option in the task conf to allow or not this feature on a par-task basis.
If an admin follow such a link, he should be r
