  • KILLSWITCH
    So my first instinct is to setup some sorta feature-flag thing within a CMS so managers can flip the boolean, I'm exploring getunleash.io and GrowthBook.io and we already use Contentful.com within the app but they're saying they "really don't think we need to use any third party thing for a killswitch"...

  • Need your opinion
    We are an Open Source Feature Flagging solution called Unleash, and we are looking to get some feedback from the community on a decision we are trying to make. We are considering offering our developers the option to either write technical content through a Community Content Program for us for a $200 fee, or to donate that amount to charity.

  • How we use analytics as a privacy focused OSS company

Mailtrap is a dummy SMTP server for testing emails sent from development and staging environments. Mailcatcher can be a replacement here. If you are looking for service, that helps to ensure your emails reach customer inboxes, you should look at Mailgun, Sendgrid, or... - Source: dev.to / 22 days ago

  • Mailtutan is an SMTP server s written in Rust for test and development environments.
    Useful. Seems very similar to MailCatcher, but not depending on Ruby is always a plus. Source: about 1 year ago

    I just upgraded to Alpine Linux 3.16.1 This is an important upgrade as it fixes 2 major issues: - busybox CVE-2022-30065 - openssl CVE-2022-2097 Related information: Mailcatcher as a docker image using Alpine Linux 3.16.1: https://hub.docker.com/r/stpaquet/alpinemailcatcher Github repo: https://github.com/spaquet/docker-alpine-mailcatcher Mailcatcher: https://mailcatcher.me.
