January 6th, 2022: What did you learn this week?

Hello 2022! For those interested, you can check out last year’s series.

It's that time of the week again. So wonderful devs, what did you learn this week? It could be programming tips, career advice etc.

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!

TimSort is usually default stable sort algorithm. I discovered it when my girlfriend ask me to help with her assignment.

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.

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!
