Below are my perspectives as a founder building…

Why Static Website Builder I had a blog that was using WordPress and it was hosted on an AWS EC2 + CloudFront CDN. It was fast and not too hard to use, except that sometimes it might break down because of a WordPress update or issues with the MySQL database.

Here is a comparison of the two environments . My goal is to use Docker for development only. When the app is deployed, it will still be deployed to App Engine Standard Environment as usual. After some researches and trial, I found…
BigQuery date partitioned tables can limit the data scan by partitions to help keep the query cost low and improve query performance. However, Google’s documents do not give much clue about how to use partitioned tables to create views that support partition queries. I did some research and found the way to do it, even with views that are created from joining partitioned tables. To expose the…

In MeasureCamp, each session has 25 minutes of presentation time, that’s where the 25 minutes on the topic from. What inspired me to do this talk was a conversation in Measure Slack about sending Google Analytics data into your own database. And I think it is an interesting…
Back in mid-2015, I created my first and only Python script so far. The script was a voice assistant. I thought I lost the source code, but it’s been in my Dropbox all the time and was named with a weird project name so I didn’t realise that’s it. I just didn’t try to look for it hard enough.
