Time tracking is a fundamental task in most companies. I used to use Clockify for a few years, primarily for its API access and the native Windows client with the mini counter.

There might be times when you want to closely follow updates to a public GitHub repository. I had this use case in June 2024 when following the Swiss NCSC for cyber threat information regarding DDoS attacks.
I solved this problem by setting up an API key and regularly querying the main branch commits. However, this process is unnecessarily complex. A much easier way is to follow a repository as an RSS feed.

ipapi.co and PowerShell free lookups
IP intelligence and looking up IP addresses has been a regular task for me for many years. Whether it’s debugging during attacks or monitoring crawler activity on websites, I have utilized various methods. I began using ipapi.co to look up IP addresses because it does not require an API key, making it convenient an it still allows for some bulk processing. This approach was ideal for the volume of lookups I performed in 2021. While this technique is still effective, exploring other options like locally hosted databases may be more appealing if you require a higher quota and performance.
Working on Azure, most application directly interact with Redis. However, for debugging or handling incidents, visibility into Redis and its storage can be beneficial. The Azure portal seems to be constantly adding more features in this area. If this is insufficient, a Redis Client can be beneficial. I personally like this client.
