Well I somehow missed that 8 digit hex codes for colours were a thing…pretty much blew my mind that I had missed this for over 6 years!

Did you know there are 4 and 8 digit hex codes (#11223344?) for colours? 🤯

Am i right?

Nick Taylor • Jan 7 '22

Yeah it's pretty neat to tweak the alpha channel.

Next someone will be telling me I can centre a <div> with just 2 lines using CSS grid! Can you imagine? 😉

I learn a lot about ClickHouse and contribute their docs frequently :).

When I see ClickHouse, I think ClickHole 🤷

Call stack resolution of .NET programs using the Trace Library can be painful. I was successful in the end, however, took time to understand what was going on.
Finished 2 books: The Psychology of Money and a book on Kaizen. Wrote notes for there here and here, respectively.
Learnt about the Peloponnesian war and the origin of war in general. Here is what I learnt: The origin of war is the competition of power and all varieties of it. Whether the power will be used for the preservation of peace or to display dominance on others or to gain wealth, it is of vital importance to the states and therefore, wars are fought to maintain or gain more power.
Learnt that to access the command line args for a process in Linux is a simple matter of reading a file e.g. in C# it's as easy as:

                return File.ReadAllText($"/proc/{ process.Id }/cmdline");

Listened to this Indie Hacker's podcast and learnt a few things about the real estate business.

I learned that each stage in a MongoDB aggregation pipeline can use a maximum of 100 MB RAM and will error if it needs more. There is an allowDiskUse option you can enable to make it use temporary files on disk to exceed that limit. Though optimizing the pipeline is a better solution when possible!

Lots of things going on, that I've learned from...

I built a Pi Cluster and learned about running tasks on multiple nodes using Slurm;
I found out about a bunch of nice CLI tools (Twitter thread);
I learned about the existence of the Open Sauced site;
and, I installed and setup a new Synology DS920+ at home, which taught me about their network stuff.

Nick Taylor • Jan 7 '22

Nice! Open Sauced is a great community. Shoutout to @bdougieyo for starting it!

I am exploring Angular combined with Ionic to contribute to an Application.

I also recently joined a new community: Virtual Coffee [as a matter of fact, I just saw you there :)] and shall be using the same to network and learn from developers around the world.

I am continuing to be more financially literate using books as my guide. I am getting more 'aware' about Fundamental Analysis.
