No-frills secret sharing with openssl

Motivation Sometimes we need to share a secret with a colleague, and frequently it’s a hassle to do so securely. Worst options include people simply sending plain-text secrets over email or slack. Better, if this is some sort of encrypted email service like ProtonMail, but still it’s a fairly brittle way if we’re dealing with… Continue reading No-frills secret sharing with openssl

PostgreSQL Fatal – semctl crash and user id

Recently spent over a week in total (maybe 2 days net time) to realize that I was hitting this postgres bug – https://bugs.launchpad.net/ubuntu/+source/postgresql-9.5/+bug/1649877 . Documenting this just in case for the future, as it was pretty non-trivial to find that this was the issue I had. The weird part was that it started happening maybe… Continue reading PostgreSQL Fatal – semctl crash and user id

Resources for promoting to Maven Central

Reminder for myself: this is a very good write up how to promote – https://dzone.com/articles/publish-your-artifacts-to-maven-central Official guide – https://central.sonatype.org/pages/releasing-the-deployment.html Requirements (very important) – https://central.sonatype.org/pages/releasing-the-deployment.html Notes for the DZone article – no need to keep gpg password in plaintext, it will prompt. However, for sonatype password it doesn’t prompt so for now my solution is to add and then… Continue reading Resources for promoting to Maven Central

Funniest thing tests were working from eclipse, but from CLI both tests and package compilation fails. Turns out Eclipse was using incorrect… Continue reading Some trouble with JUnit 5 and solution
