Programming Course Series [01 – Introductory course to python]

Computer programming is important today because so much of our world is automated. Humans need to be able to control the interaction between people and machines. Since computers and machines are able to do things so efficiently and accurately, we use computer programming to harness that computing power.

This is the first of hopefully many programming courses that can introduce technically inclined people to Python programming.

Topic:

Everybody can write a computer program (An introduction using Python)


Agenda

Introduction to programming and reasons to write programs?

These are the course-wide materials as well as Introductions’ first section where we discuss what writing programs mean. In the third part of the class, we will finish the Introduction and have the quiz and first task.

Installing and Using Python

We’re going to set up stuff so that you can write Python programs.

Introduction to programming and reasons to write programs? (continued)

We try to cover the “big picture” of programming so that you get a “table of contents” from what to expect to learn. Don’t worry if, the first time you hear it, not everything makes perfect sense. This part is very broad.

Variables and Expressions

We will explain how a program uses the memory of the machine to store, retrieve and process information in this section.

Conditional Code

We will move from sequential code in this section that simply runs one line of code after another to conditional code where some steps are skipped. It is a very basic idea – but it is how “choices” are made by computer software.

Functions

We are going to learn about what functions are and how we can use them. Functions will be an essential way for us to make sense of our code, as we move into more and more complicated programs.

Loops and Iteration

Our four fundamental programming patterns are completed by loops and iteration. Loops are the way we say Python over and over to do something. Loops are the manner in which we create programs that remain with a problem until the problem is solved.


Increase volume in video using ffmpeg

A quick note on how to boost the audio stream in a video using the volume filter in ffmpeg

#;For newer versions of ffmpeg
ffmpeg -i input.mkv -filter:a "volume=4.0" output.mkv;
#For older versions of ffmpeg (we use multiples of 256)
ffmpeg -i input.mkv -vol 1024 -vcodec copy output.mkv;

Using the above command we were able to make the audio LOUDER!


Lenovo Legion Y520 – Black Screen After RAM Upgrade to 32GB (2x16GB)

Recently, we updated the RAM modules of a Lenovo Legion Y520 from 16GB (2x8GB) to 32GB using two HyperX Impact DDR4 16GB, 2400MHz CL14 SODIMM modules.

Right after installing the new modules, after power on the laptop it would show a black screen, the fans would work at full speed but nothing else would happen. We tried placing the old RAM back inside but with no success, the same bad behavior would occur.

Since the battery of this laptop is bolted onto the chassis we thought that we might have to give it a “hard restart” or something to get it started.

Our solution

1) We powered off the laptop by long pressing the power button. 2) Then we released the button and long pressed it again until the laptop powered on and off again.
The next time we powered on the laptop it was working perfectly again!!
