April 8, 2020Log Rotation for Python Applications - Without killing them softlyA couple of days after a successful deployment of my Zope 4 application, I noticed something worrisome. Zope gets killed every night, shortly after midnight. I use Supervisor, which monitors the process and restarts it, so that’s not the problem. But there are two problems: I did not trigger this on purpose. The cache of my app is cold, that means that my colleagues get slow response times for the first queries in the morning....
February 23, 2020isort and pre-commit - a friendship with obstaclesNote This post is not intended to be an exhaustive introduction to pre-commit and its hooks. Please visit pre-commit.com for a complete documentation. In a nutshell… pre-commit From its website: A framework for managing and maintaining multi-language pre-commit hooks. Very simplified this means, whenever you try to commit changes in your project (e.g. entering git commit), pre-commit runs all configured tools (e.g. linter, formatter, …), and only if they run successfully, your commit will be executed - otherwise your commit will fail....
November 26, 2019Three Ways to Get Into Trouble or Welcome Back PageTemplateEngineThe web application server Zope has a very long history which dates back to the late ’90s. Quoting Martijn Faassen: Zope must be one of the oldest Python codebases in the world that is still used outside the standard library. During its many years of existence the way a view gets rendered has changed. Basically there are two supported template mechanisms: Document Template Markup Language (DTML) Zope Page Templates (ZPT) DTML is pretty much outdated for more than a decade, but still in use for the Zope Management Interface....

May 10, 2019Chrome No Longer Shows Saved PasswordsConcerning security and privacy, you either can get stalled because you can’t get it perfect right from the beginning, or you improve over time. I prefer the latter one. And concerning password security I go with Troy Hunt: Password managers don’t have to be perfect, they just have to be better than not having one. And actually the password manager of a browser is already a password manager. I would not use it for very important passwords, but it is absolutely fine for those dozens of dozens forum logins and so on....
