Which Language Should I Build This Software In? or Which language should I have this software developed In?

This is a question that software devs gets asked a lot. By there friends/colleague , usually by who are not part of the software industry. This is my answer to them:

If you had an idea for a novel? or a poem? which language will you write it in. Italian, Tamil, Bengali? Would you try to learn a new language because there are a lot of similar novels (anime) in Chinese or Japanese.

The best language to write your novel is the language you know the most.

ESP 32 is a series of low-cost, low-power system on chip micro controllers with integrated Wi-FI and Bluetooth. SoC or system on chip is an integrated circuit that integrates all or most of the component of a computer. Example the CPU, RAM, IO interface, GPU, etc. This form is becoming more and more popular thanks to growing smartphone and computing industry. Apple M1 chip is a good example on the direction in which SoC’s are going.

The ESP 32 is really low cost it cost like 350 in India, and less than 10$ in the US. Now when you buy this you don’t buy the chip alone, but a chip on a development board. There are several articles (https://makeradvisor.com/esp32-development-boards-review-comparison/) on that. The board that I bought from amazon was this https://www.amazon.com/dp/B0718T232Z?psc=1&ref=ppx_yo2ov_dt_b_product_details, i also bought one with OLED display as well https://www.amazon.com/dp/B07DKD79Y9?psc=1&ref=ppx_yo2ov_dt_b_product_details.

In this article I will be talking about how to get started. We will basically will be setting up Aurdino IDE in linux, followed by flashing few sample programs like:

I am a developer who moved from Windows, to Linux, to macOS, to Linux. A typical developer’s journey 😆. So moving from windows to Linux was over 13-14 years ago. I didn’t do much from the windows world other than games and single executable files. But moving from macOS to Linux, has been a bit tough. KDE has been able to provide me with everything I want and more. The one thing that I missed the most was the emoji keyboard, with easy to launch shortcut.

My usage of emoji was at its peak during macOS days, I used emoji for my communications, commits, function name and even terminal aliases. 😈 Not everyone was a fan of my emoji usages, but I loved it.

Note: I am using Apartment gem to manage my multi schema database, and this article is written with expectation you know and use that gem.

When you have multiple schema in your rails application, it is important for them to remain consistent. Rails migration is run by keeping track of the timestamp prefixed in front of its file name. It stores the database. So when you restore a schema that hasn’t ran the migration, but rest of the schemas has it, rails thinks it has already ran the migration. Rails look at the main / default schema to know if it has ran the migrations and then follow up on the rest.

Accessing the list of commands you have ran in your irb or rails console. Running the following command in your console Readline::HISTORY.to_a returns the array of commands you have typed in console. After which you can treat it like any other array in ruby - search, sort, etc.
