I am working on integrating additional sources, and Linkedin will be definitely one of them.

After some research, my hypothesis might be wrong. Comparing the different data sources I have found out that there is a drop only in one them, so my best guest is that an increase in the job post price or a change in the business model (e.g. shortening the length of the time a job is posted) is the most likely reason for the drop we can see in November.

OP's disclaimer: I started this hobby project one year ago. The point of this project was and still is to learn about new technologies. Maybe I am lacking the statistical background, or the data since it goes back only 13 months, to make such an statement but when I starting seeing these trends in the number of job posts, I thought that it would be interested to share it in the Hacker News community and get some feedback.

About whether these trends that we see in the graphs are something real or just a data issue like seasonality or a problem with the data sources, I think we will soon know from the mainstream media. As always the time will tell.

I don't think so, note how last year, there was still a small job post increase from middle of November until end of December.

As the Dash frontend wasn't able to handle the traffic I have replaced the dynamic dashboard with static HTML, sorry for that. I will replace it with the real dashboard when I am able to handle the traffic.

I would take no offence, the dashboard is implemented with https://dash.plotly.com/ which is a great tool for prototyping but doesn't seem to handle concurrent users very well.

Then good luck with that. I remember 2009 which was also a hard year but it wasn't impossible. Maybe start right after you are done.

Unfortunately, I have data only from October 2021, that's why the longest time filter is 12 months.

I cannot say if it is a law or the pricing plan but 30 days seems to be the most recurrent job post length.

That means that the crash probably started in October and we started seeing it on the data at the beginning of November.

It seems that Dash cannot take the Hacker News traffic, here is a screenshot until it is online again: https://gcdnb.pbrd.co/images/ElMG6yee19KT.png?o=1

Good point, now the y-axis starts at 0 but even now we can appreciate how abrupt the fall is.

I find Vue easier to learn than React and its documentation is great.

The STACKIT website works for me.
