Publish Parts Of Obsidian To My Personal Site

 Posted on 2021-08-09  (Last modified on 2023-10-18)

The idea at the start was simple. Do something like Obsidian Publish , so read frontmatter and if it contains published: True put it up on a website to view. Info I have since rewritten and updated this tool: New version The Basics I started with taking a look at different static site generators but after a bit of testing I ended up back at Hugo, which I already use for ps1.

curl: Modify DNS Resolution

 Posted on 2021-08-08  (Last modified on 2021-08-12)

You can intercept normal name resolution in curl with the --resolve parameter allowing you to do things like talk to a specific site of a DNS load-balanced setup or talk to a new deployment not yet made productive. You can specify the resolve option multiple times so you can even catch redirects and move them to where you want as well. It’s important to note that this intercept does only work on the ports you specify in the entries. [Read More]

How SELinux screws with scripts when run over VMware Tools

 Posted on 2021-08-08  (Last modified on 2021-08-11)

SELinux by default prohibits certain things from working through VMware tools (Ansible connection or plain API).

This can be solved two ways:

  • Disabling SELinux: BAD, but easy
  • Writing a custom SELinux policy: complicated but more secure

Note: Adding/Changing this policy through a VMware tools connection is thankfully possible

Example policy

This policy is the base for a VMware tools policy and allows entering the rpm context (yum).

module custom-vmtools 1.0;

require {
        type rpm_script_t;
        type vmtools_unconfined_t;
        class process transition;
}

#============= vmtools_unconfined_t ==============

allow vmtools_unconfined_t rpm_script_t:process transition

Replace Line In YAML While Keeping Indentation Using Ansible

 Posted on 2021-08-08  (Last modified on 2025-02-26)

In theory Ansible should be declarative and have full control over the systems we touch with it. In practice, this is unfortunately not always the case. This combination of tasks loads a given yaml file from the remote host, combines a “overwrite dict” onto it, and writes the file back to disk. - name: Load yaml file contents as fact ansible.builtin.slurp: src: /etc/some-file.yaml register: yaml_file - name: Parse yaml file contents ansible.

Looping Dates macOS

 Posted on 2021-08-07  (Last modified on 2021-08-09)

date on MacOS does not support --date, so a workaround is needed. Converting Date to unix epoch, adding one day in epoch and converting back. The Scripty Way Taken from a blog post #!/bin/zsh start=$year-01-01 end=$year-12-31 currentDateTs=$(date -j -f "%Y-%m-%d" $start "+%s") endDateTs=$(date -j -f "%Y-%m-%d" $end "+%s") offset=86400 while [ "$currentDateTs" -le "$endDateTs" ] do date=$(date -j -f "%s" $currentDateTs "+%Y-%m-%d") echo $date currentDateTs=$(($currentDateTs+$offset)) done The Brew Way As I found out long after writing the above you can simply brew install coreutils and get a date command with the --date option.

GitLab Merge Request from the CLI

Speed up your work with git by automatically creating Merge Requests for your git push

 Posted on 2021-05-06  (Last modified on 2025-03-14)

The Problem You want to push a branch to GitLab and automatically create a Merge Request (MR) for it. There are effectively three scenarios this can cover: Create a MR in draft state with a custom title Create a MR Create a MR and automatically merge if CI/CD pipeline succeeds Manually this is quite the process: Push branch to origin Copy link to create a MR Open the link, change fields to represent wanted state and submit The Solution GitLab offers push options1 that allow us to instruct it to do more than just plain git push.

GumLab

My first ever product

 Posted on 2021-01-04  (Last modified on 2025-03-14)

As part of my goal to write a book I began looking at how to build a following and where to sell the book once it’s finished. On this journey I found Gumroad, a great place to sell digital products. Given my idea to sell a comprehensive library of code snippets besides the actual book I took a look at existing integrations between it and GitLab.com, my preferred git host. [Read More]

Delete Your Old VMware Snapshots

 Posted on 2021-01-01  (Last modified on 2025-03-14)

For the love of Pete, please delete your old snapshots regularly! Old snapshots have caused incidents and even outages more than once in my career and it is really easy to preemptively look for them and get them removed before anything happens. Why To put it plainly, they can cause issues - like 03:00 in the morning pager alert issues and additionally eat up storage space like crazy. Degraded performance of the VM having the snapshot Degraded performance to full outages for other VMs on the same data store due to rapidly increasing snapshot sizes VMware recommends a series of steps to reduce risk when using snapshots: [Read More]

My Stand On Affiliate Links

What I think about affiliate links

 Posted on 2020-12-17  (Last modified on 2025-03-14)

Lets talk about affiliate links for a moment. TLDR: I will use affiliate links where it is possible for me, which isn’t often to be honest. Lets dig into it, starting with some basic assumptions I am making: Most of my posts are technical content where I do not recommend any products or services, so there are no opportunities for affiliate links to begin with In posts where I reference a product or service I do so because I think it is great and I really want to recommend it There are no negative effects for the reader when using my affiliate links There are benefits for me when you use the affiliate link, either monetary or in credit with the service - This helps me keep this blog up and running for everyone to benefit Given those assumptions I don’t see any reason why I should not use affiliate links.

Super-Charged Cmdlet Aliases

It works like magic, but it works - Bring your aliasing to a whole other level!

 Posted on 2020-12-02  (Last modified on 2025-03-14)

Backstory I recently wrote a post about PowerShell Aliasing for the folks over at ScriptRunner. The one issue I had while researching for this post was this: You can not create a alias for a function and overwrite one of it’s parameters at the same time while keeping nice features like tab-complete. For a concrete example of this visit please look at the original post. At the end of the post I asked if anyone had a solution to this problem - and the internet delivered! [Read More]
