After Attending a Wolfram U Webinar (Hands-on Start to Wolfram Mathematica)

Webinars are scheduled online events aimed at having a seminar-like experience over the web. I recently took the Hands-on Start to Wolfram Mathematica training tutorial. The event lasted for about one hour and forty-five minutes; but it could last up to two hours.

The webinar had about 3 breaks, giving time to ask written questions, that the team behind the seminar would answer. In these forum-like chat you are allowed to post questions regarding the presentation, and in this one in particular, you could ask for any short explanations on Mathematica's functions and capabilities.

As stated on the tutorial's title, the lesson is "hands on [the software]", therefore, if you don't have a Wolfram Mathematica license, you will be handed and email with a link to redeem a 15 day license.

During the lesson, the instructor writes a Mathematica notebook, which can be copied step by step by the attendants however not everyone is able to type in as fast. That being so, they offer you a copy of the final notebook of the lesson if you have bought the book with the same title. If you haven't by then, you can still ask for them to hand it over. As a result, you will receive an email stating that you must register your book in order to verify your purchase. Are you still worried you may have forgotten something else? Don't worry, as soon as they publish a video of the lesson, you'll be given through your mailbox a link to see it.

Hands-on Start to Wolfram Mathematica tutorial is a nice way to start with Mathematica and the Wolfram Language, you can also purchase the book to get a deeper and further stated introduction. The seminar basically comprises the first few chapters of the book.

My recommendations
Set up your computer with a second screen, specially if you are on a laptop (receiving the lecture on a 11 inch screen was uncomfortable). The ideal setup is to have the webinar in one screen and Mathematica on the other one. You will deal with multiple Mathematica windows, so a proper space for them would boost your performance.

The Ominous Experience of Camping Under The Rain

Easy setup, pop up tent, so enticing, I was lured into the purchase of a Pavillo (camping gear) series Nucamp X4 Tent by Bestway because it had an auto expandable setup. No more manually extending the fabrics and getting the rods straight and in. Reading into the key features, the tent had waterproof seams and a water resistant fabric (PU2000mm). The last number means that the fabric can withhold up to 2000mmH2O of pressure, thus it doesn't necessarily mean that there is more plastic in the fabric nor it is thicker. Then add up a mild storm like rain plus powerful wind blows, and you are doomed. Sleeping on the inside I began to feel a mild sprinkle on my face, there were little droplets of water exuding from the fabrics. The harsher the climatic conditions turned, the fatter the drops. I ended up drying the fabrics with a towel. On the other hand, not all the seams were waterproof. The one I had my head under, dripped continuously.

It was a rough night. Nevertheless, my tent was one of the ones that endured the most. A third of the camping tents collapsed on the floor, due to the wind, with their occupants inside. Others became seriously flodded or blown away. Mine barely stood up.

YouTube's Dilema with Demonetization and Misinterpreted "Copyright"

Recently there was kind of a scandal regarding YouTube and what content is "eligible" for monetization. I am not going to talk about that scandal nor the shutdown of YouTube channels due to infringing on the rules. I will cover this as an amateur content producer on YouTube.

To start, it's quite easy to get an Adsense license to be able to monetize your YouTube videos with advertising. I began to screen my gameplay on different games. The app I used to screen them didn't record the game audio. In order to put music on my videos, I began making loop-based Garage Band soundtracks. Garage Band's loops are royalty-free. This means you can make your loop-based soundtracks and sell and be free of charge to use them on your work. This soundtracks can even be sold and you aren't liable for selling content that includes royalty-free loops.

I incorporated my soundtracks to the videos and uploaded to YouTube. Hours, minutes or months after the video's publication, I received a message like the following.

A copyright owner using Content ID claimed some material in your video. This is just a heads up
Don’t worry. You’re not in trouble and your account standing is not affected by this. There are either ads running on your video, with the revenue going to the copyright owner, or the copyright owner is receiving stats about your video’s views.  
Video title: “Name of the video”  
Copyrighted content: Acoustic Band  
Claimed by: TuneCore 

What happened? There are people who made soundtracks based on royalty-free loops and sold them. Their record companies have bots on sites like YouTube and denounce a copyright infringement. But you never did that copyright infringement. Those bots as well as the record companies should know that you can't claim for copyright infringement in royalty-free content.

How this affects content creators? Since the claim, creators can't monetize their claimed content until a dispute is won against the claimer. I normally wrote a text saying that I used royalty-free loops from Garage Band, so the claim should have no action on my content. The claimer has around thirty days to answer your dispute. You know you are right, but normally they answer the dispute until the thirtieth day. You won the claim and now you are able to keep monetizing your video, but you might as well receive more claims on the same video. I have received copyright claims even of songs created on a latter period than my own. This is unacceptable. Probably other content creators have suffered the same process.
