sla: The Simple Little Automator

I’m tired of using Make and its arcane syntax. 90% of the projects I write or deal with don’t require any kind of incremental compilation, but that’s all any build system talks about. That, and how insanely fast it is. The drawback is usually that you need to install several terabytes of dependencies, and then […]

multi-git-status can now do a “git fetch” for each repo.

Just a quick note: My multi-git-status project can now do a “git fetch” for each repo, before showing the status. This fetches the latest changes in the remote repository (without changing anything in your local checked out branch), so that mgitstatus will also show any “git pull”s you’d have to do. 

direnv: Directory-specific environments

Over the course of a single day I might work on a dozen different admin or development projects. In the morning I could be hacking on some Zabbix monitoring scripts, in the afternoon on auto-generated documentation and in the evening on a Python or C project. I try to keep my system clean and my projects […]

SSL/TLS client certificate verification with Python v3.4+ SSLContext

Normally, an SSL/TLS client verifies the server’s certificate. It’s also possible for the server to require a signed certificate from the client. These are called Client Certificates. This ensures that not only can the client trust the server, but the server can also trusts the client. Traditionally in Python, you’d pass the ca_certs parameter to the […]

A short security review of Bitwarden

Update: Kyle Spearrin, the lead developer of Bitwarden, contacted me regarding this blog post. Some issues (unnecessary loading of resources from CDNs and disclosure of my email address to a third-party without confirmation) have already been resolved. Mitigations for other issues were already in place, although I haven’t had time to confirm this yet. I’ll update this […]

Multi-git-status now shows branches with no upstream

Just a quick update on Multi-git-status. It now also shows branches with no upstream. These are typically branches created locally that haven’t been configured to track a local or remote branch. Any changes in those branches are lost when the repo is removed from your machine. Additionally, multi-git-status now handles branches with slashes in them […]

Restic (backup) deleting old backups is extremely slow

Here’s a very quick note: I’ve been using the Restic backup tool with the SFTP backend for a while now, and so far it was great. Until I tried to prune some old backups. It takes two hours to prune 1 GiB of data from a 15 GiB backup. During that time, you cannot create […]

Lurch: a unixy launcher and auto-typer

I cobbled together a unixy command / application launcher and auto-typer. I’ve dubbed it Lurch. Features: Fuzzy filtering as-you-type. Execute commands. Open new browser tabs. Auto-type into currently focussed window Auto-type TOTP / rfc6238 / two-factor / Google Authenticator codes. Unixy and composable. Reads entries from stdin. You can use and combine these features to […]

multi-git-status can now hide repos that don’t need attention

I’ve added an “-e” argument to my multi-git-status project. It hides repositories that have no unpushed, untracked or uncommitted changes. Without “-e”: And with the “-e” argument:

Ansible-cmdb v1.26: Generate a host overview of Ansible facts.

I’ve just released ansible-cmdb v1.26. Ansible-cmdb takes the output of Ansible’s fact gathering and converts it into a static HTML overview page containing system configuration information. It supports multiple templates (fancy html, txt, markdown, json and sql) and extending information gathered by Ansible with custom data. This release includes the following features and improvements: Custom and host local facts […]
