Why would we go beyond step 2? As a taxpayer, I could buy the argument that the govt needs a new font, and that, having made one, it should make said font available for free so taxpayers can get the benefit. I don't see why my taxes sh

Verifying a user's email by collecting their password is ineffective for users with 2FA enabled and reckless/malicious for those (the majority) without it. Accidentally log that data somewhere, and you've opened a way for att

Arguably, giving up your email login is worse than giving up your banking login, since attackers could use your email to reset the password on other accounts, possibly including bank accounts. For banking, a better system would allow you to

I think password management is a good fit for Mozilla. I perceive Mozilla to be trustworthy and competent, and the code for this is open source: https://github.com/mozilla-lockbox They also generally do a good job with UI,

The bullet gem has helped me solve this problem in specific applications before, yes. My higher-level problem is that having lazy-loading on by default allows N+1 queries to creep in to a code base and you need a third-party gem to find the

I haven't used Node, but I think it's funny how they tout asynchronous IO via callbacks. Meanwhile the BEAM has that plus asynchronous computation - you just write synchronous code and let the scheduler pause your BEAM process as

I know how to preload associations, but I don't know how to globally disable lazy loading of associations. Do you know a way?

by nathan_long 8y ago
Yep, I used it extensively on one project, configuring it to raise exceptions if it detected an N+1 query and gradually enabling it test by test as I fixed them. It's very helpful.

A genetic test to see whether someone has ancestry from Melenasia or Sudan or Scotland is likely to give a different result than casual visual classification. The latter is what we commonly call "race".

I have also heard of medical examples like that. However, this article argues that generalizations based on apparent racial characteristics are medically unreliable. https://www.scientificamerican.com/article/race-is-a-
