This is a crosspost from my TIL What the heck is .PHONY in makefile? I have seen this for so long but I always shrugged off. Whatever that is. Well, finally I decided to learn about it. A bit of introduction to Makefile syntax. target: prerequisites <TAB> recipe The first target in a Makefile will be executed by default when we call make. blah: blah.o cc blah.o -o blah # Runs third blah.

Libpq-Postgres-Go After I started working on Postgres, I have heard this term libpq enough times, but never had a good grasp of it. After digging around this topic for a couple of days, here is my understanding. From the Postgres doc https://www.postgresql.org/docs/9.5/libpq.html, libpq is the C application programmer’s interface to PostgreSQL. libpq is a set of library functions that allow client programs to pass queries to the PostgreSQL backend server and to receive the results of these queries

This aricle is inspired by Give and Take by Adam Grant. I was wondering how can I help my friends and network. Searching a job is something stressful and we all have been through. Once my wife and I searched for a year and finally we moved to San Francisco. So far its been a challenge for my network to know whether I can refer to a particular company. To solve this, I am publishing a list of companies where I can refer.

In Google Cloud Next 2019, they introduced a new product called Cloud Run. I’ve been using it from the EAP (Early Access Program) days. [As the name suggests, basically it runs your docker image. You might be familiar with other serverless products such as Cloud Function or lambda where you provide your source code instead of a docker image. In my opinion, Cloud Run is more flexible than functions. Let me explain why.

Step 1: Setting up HAProxy I hope you gone through Part1 of this series. Perhaps, one thing you might have noticed is that I’ve to connect to the specific master database. In our case, since both the databases are running on docker, only the localhost port is different. (In a production environment, most likely you going to run the databases on a different host). The main reason for active-active replication is high availability.

Postgres doesn’t support active-active replication natively. As of this writing, we have to rely on 3rd party tools. I decided to go with BDR. I didn’t want to spin up multiple VMs. So, the obvious choice is docker. Make sure you have docker on mac & docker compose. Step1: Running 2 Postgres instances using docker container Thanks to jgiannuzzi, who created a docker image with Postgres and BDR. docker-compose.yml file content
