My room is now a complete program development room, with six displays in front of me.

However, they are still not enough.

I am working on a network program using Raspi 4 but struggling with this development environment.

Especially in networking, multiple displays are desirable because I have to debug while looking at both the sending and receiving sides.

However, I didn't want to buy a display now, and I suddenly saw a PC in the living room.

My daughter lives on a laptop + iPad, and my wife makes airline reservations from her phone.

Our shared PC seems to have already done its job.

So, I snatched two old displays from a family PC.

The problem is that the interface is an old standard (VGA). However, I resolve it with a conversion cable.

I was surprised to learn that Raspi 4 has had two display interfaces from the beginning.

Even laptops only have one HDMI interface. Where the heck is the Raspi going? Thanks, though.

By the way, last month, at the request of my professor (or rather, as a departmental unit), I built a database server with Raspi and delivered it to a university laboratory.

It would be great if students could become proficient in using this database server, but as far as I know, I have not seen any students programming it (maybe they are doing it at home).

Still, I try not to say, 'Programming will expand your world.

I have seen so many people who talk about "programming" as "Islam," "judo," "soccer," "English," etc., that I am sick and tired of it.

It is the same as this story. I want to say that

"I say 'congratulations' to you for expanding your world. But don't push it on me. It's annoying."
