@squaremeafrica right now, it's even difficult to pick. Transport fare or erratic light. May be fuel because of the cost of transportation

@squaremeafrica My mum had to hawk at some point for me when I was in the university. She went from house to house selling crayfish.

Yesterday, I was trying to book a train ticket. The moment the site opened around 4:30pm, Coach 1 was already fully booked. I panicked and quickly checked Coach 2, which was almost full as well.

So I immediately moved to Coach 5, where there were only a few seats left. I booked one right away. Within 20 minutes, every single seat was gone.

But let me tell you what really happened when I got to the train station this morning.

People were there buying tickets directly from staff. That means a large number of seats were likely held back and later sold at outrageous prices. That is not business. It feels criminal.

Situations like this are why progress feels so difficult. When systems are manipulated and ordinary people are forced to pay more just to survive, it damages trust and fairness.

Nigeria cannot move forward if integrity is constantly sacrificed for quick profit.

So you say you are a software engineer.

Have you ever downloaded actual binaries like Kafka, Postgres, ClickHouse, Elasticsearch, Redis, or something else, and tried running them locally while exploring what those bin, lib, data, and logs, etc directories contain?

And then did you understand why they expose specific ports, what exactly gets written inside the data directory, and why in that particular format?

Did you then write your own client to call their APIs and bombard the server with requests, just to observe when CPU becomes the bottleneck, when RAM starts limiting scale, and how the system degrades under pressure?

After that, did you run the same systems inside Docker or Podman and experiment with controlling memory, security and disk limits to see how resource isolation affects behavior?

Did you go one step further and install Minikube locally, to orchestrate multiple instances of your container, simulate a multi-node cluster, and understand ingress and load balancing in practice?

And then maybe, did you spin up a free AWS EC2 instance and repeat everything on a real remote machine to understand how ssh works and how distributed systems behave outside your laptop?

Or is your definition of backend engineering still limited to APIs plumbing?

Who has used a Gantt chart as a software engineer? What did it help you achieve?

[Amaobi Victor @AmaobiVictor]

I have been debugging a webpack issue till 5pm when work closed. Went back home to look at it again. Very tired

[Amaobi Victor @AmaobiVictor]

Today, I used docker compose. Not the first time using it though but first time using it with flask. The app uses redis to calculate the number of times the flask app is opened. I will be looking at pushing my images to AWS ECR

@Corballyred Salah back on pens? He just missed with Egypt. These things happen plus Dominic's conversion rate still superb.

If, however, the requirements.txt remains the same after the first run, the pip install command will not rerun during our development when our code changes, helping us speed development and testing

[Amaobi Victor @AmaobiVictor]

I have used Docker enough, but today I appreciate Docker caching. For example, you may be tempted to copy all your files before running your installation command.
COPY . .
But breaking it down into three steps makes more sense.

[Amaobi Victor @AmaobiVictor]

requirements.txt changes rarely
The pip install command is slow. The rest of the files change frequently. To help us reduce our build time, docker will cache the layers

[Amaobi Victor @AmaobiVictor]

Copying requirements will only rerun during the second build phase if the requirements.txt file changes. When that runs, however, every other command after it will run because of the change.

I ending last year taking my focus on taking my devops practice to the next level.

I started small and though I have skipped some updates, I will like to mention that today, I was able to create an s3 bucket, add a dummy file to it, delete the file and then delete the bucket using python
