Arthur C. Clarke’s or Isaac Asimov’s writings are imaginative and uncommon stories. Lately, I have discovered two authors that blend science fiction with humor. These have been a blast to read. The culprits are Douglas Adams and Rob Grant. If you can find yourself a copy of “The Hitchhiker’s Guide to the Galaxy” by Adams, or “Colony” and “Incompetence” by Grant you are in for some peals of laughter.https://ingxfm.github.io/en/blog/assign_usb/Fri, 22 Nov 2024 10:03:39 +0100https://ingxfm.github.io/en/blog/assign_usb/You need to connect 3 USB cables to an Ubuntu 22.04 workstation. These 3 USB cables are 1 UART 232TTL USB converter cable and 2 RS485 USB converter cables. You have needed to reboot this workstation a few times. Or connect and disconnect the cables and you noticed that the naming (/dev/ttyUSB0, /dev/ttyUSB1, /dev/ttyUSB2) of the cables as serial ports are changing in your Ubuntu OS. Because you are running a program that is using this names you would like them to stay fixed for each cable.https://ingxfm.github.io/en/blog/about_page_update/Wed, 20 Nov 2024 16:46:45 +0100https://ingxfm.github.io/en/blog/about_page_update/Let’s start compiling a list of spots in the World Wide Web that I have found useful, enjoyable and/or humorous. In this first time, we will add 4 entries in no particular order of importance. Go to my About page.

For example, I want to know how to say a few Japanese words: Yes - Jai No - Iie Thank you - Arigatougotzaimasu I’m sorry - Gomennasai Excuse me - Sumimasen Imagine entering your house and a man breaks the entrance with a karate chop shouting Jaaaaaaaaiii! The karateka is nodding a yes with exaggerated head up and down movements.https://ingxfm.github.io/en/blog/criticizing_book/Fri, 01 Nov 2024 20:21:55 +0100https://ingxfm.github.io/en/blog/criticizing_book/What we know, we know subject to correction; we know it because all, or at least the weight, of the evidence supports it, but we are not and cannot be certain that new evidence will not sometime invalidate what we now believe is true. Mortimer Adler and Charles Van Doren. Until Albert Einstein came along with his theory of relativity, there was a concept called aether, or ether, that was used to describing the behavior of light.https://ingxfm.github.io/en/blog/preguntas_sistema_estudio/Wed, 30 Oct 2024 19:50:30 +0100https://ingxfm.github.io/en/blog/preguntas_sistema_estudio/You found a new job opportunity that could double your income. But, to get it, you need to pass the loathsome certification exam in 3 months. Furthermore, you have years you do not study (bad, you should be constantly learning). Moreover, you work from 8 to 5. But OK, let’s leave aside the scolding. How will we recover our study habits? Bro, I never had one! OK, Joe, if you never had these, let’s ask some questions to evaluate our state.https://ingxfm.github.io/en/blog/ffmpeg_rotate_video/Fri, 25 Oct 2024 20:13:03 +0200https://ingxfm.github.io/en/blog/ffmpeg_rotate_video/Let’s say you stupidly recorded a video vertically, and when you copy it into your PC the video is saved horizontally. So, you have a vertical video, which in itself is a blasphemy already, playing horizontally. Let’s rotate this video so that it continues its sinful vertical ways. Or you can get yourself a visit to the neck doctor. After me. Let’s use the wonderful ffmpeg. There is the so-called transpose parameter that you can pass:https://ingxfm.github.io/en/blog/syntopical_reading_be_less_wrong/Wed, 23 Oct 2024 20:47:20 +0200https://ingxfm.github.io/en/blog/syntopical_reading_be_less_wrong/I had this question: How to be less wrong in my career? To answer that question, I reflected on what I have done so far in my career and read the books below. The following are my notes from the books. Note from the syntopical reading of the following books How to read a book by Mortimer Adler and Charles Van Doren Seven habits of highly effective by Stephen Covey Smartphone, dumbphone by Allen Carr The easy way to mindfulness by Allen Carr Good sugar, bad sugar by Allen Carr Atomic habits by James Clear The subtle art of not giving a fuck by Mark Manson So good they can’t ignore you by Cal Newport Ikigai by Hector García The art of learning by Josh Waitzkin The advice to follow your passion is an addiction.https://ingxfm.github.io/en/blog/zotero_start_menu/Fri, 18 Oct 2024 22:08:44 +0200https://ingxfm.github.io/en/blog/zotero_start_menu/When you install a drawing program in Linux and suddenly… (ಠ_ಠ) Imagine you have installed an application in Discover in your Kubuntu 22.04. For whatever reason, you cannot find it when you are supposed to be seeing it in the start menu. Fear not. So, it happens that for an application to be shown in the start it needs to be added in the directory /usr/share/applications.

This poor soul needed a few screenshots and lo and behold his Spectacle tool presented a not so spectacular behavior. Spectacle required the following actions to make one screenshot: open Spectacle -> Area: Rectangular Region -> click on Take a New Screenshot, the mouse pointer disappears, then open again Spectacle from Super -> click again, take a New Screenshot, then I could see the pointer normally.https://ingxfm.github.io/en/blog/hobbies_for_engineers/Fri, 04 Oct 2024 11:01:15 +0200https://ingxfm.github.io/en/blog/hobbies_for_engineers/Do you work as an engineer and want to pick a hobby so that you can put in practice outside of work some of the math, natural and/or social science principles you have learned? Let’s take a look at some nice hobby ideas. Cars There are many possibilities related to these vehicles. What about getting involved in the maintenance of the car? What about some modifications to the headlights, or the suspensions?https://ingxfm.github.io/en/blog/anki_intro/Wed, 02 Oct 2024 21:56:43 +0200https://ingxfm.github.io/en/blog/anki_intro/Have you ever studied a new material, and have forgotten almost immediately after using it (for work, or for an exam)? Have you ever forgotten something you thought you had understood well? Are you trying to learn a new language and forget the new vocabulary all the time? Well, that happens to me, as well. You are not alone. In my case, I have found a solution in the form of a technique, the so-called spaced repetition.https://ingxfm.github.io/en/blog/tail_linux_ubuntu/Fri, 27 Sep 2024 08:00:00 +0200https://ingxfm.github.io/en/blog/tail_linux_ubuntu/When monitoring any program logs in Ubuntu or in many Linux based operating systems one can use the tail command. The tail command outputs the last lines of a text file. Enter the command in the shell program. tail /<path>/logfile.log By default, the tail command will show the last 10 lines. If you want to specify the number of lines, enter the command with the flag “-n”, in the following way:https://ingxfm.github.io/en/blog/vida_cotidiana/Wed, 25 Sep 2024 06:11:08 +0200https://ingxfm.github.io/en/blog/vida_cotidiana/Everyday life in the hood is so much better when we tamper down our hormones. I have tested it myself. I used to live in a hood where normal everyday people would throw trash anywhere. Furthermore, they would blast their music at eardrum-damaging volume. Moreover, you were always worried someone was going to ask you with a lack of courtesy to hand him over the nice looking belongings you were carrying, even midday.https://ingxfm.github.io/en/blog/how_to_read_a_book_ma/Fri, 20 Sep 2024 18:54:18 +0200https://ingxfm.github.io/en/blog/how_to_read_a_book_ma/There is a book close to my heart because it dawned on me how below average one can act. In my search for being less stupid, I read “How to read a book by Mortimer Adler and Charles Van Doren (edition 1972)”. Let’s call this book HRB. Notes: This is a practical How-to book that explains how to read better if our goal is lifting our mind from understanding less to understanding more, to knowing more about life, the world, and ourselves.
