The team over at OpenAI have been working on a neural net capable of spontaneously generating novel music, and it is currently considered state-of-the-art in this field. Their approach involves modeling raw audio waveforms — a departure from previous attempts that developed music symbolically (i.e. piano rolls). This has a number of implications for the results of the models’ output, the most important being the ability to replicate the human voice while singing. And they’ve made all of their code and the trained model publicly available so that we can try it out for ourselves.

The jukebox website can be found here, but for convenience you can click this link to open a Google Colab page with a python notebook containing all of the setup and example usage for generating music with the Jukebox model. …


So I recently heard about Yotta Bank from a Graham Stephan video. It is essentially a high-yield savings bank except that they gamify the savings using a lottery system.

The whole principle of it described by Graham was really intriguing and I love the concept that it might actually encourage a lot of low-income individuals to invest their money with Yotta instead of wasting it on an actual lottery.

But there was one aspect of Graham’s video that bothered me, and that was the claimed annual percent yield. The annual percent yield (APY), if you don’t know, is a value that describes how much money you could earn on interest just by holding your money in that bank account. As an example, if you have $5,000 in a high-yield bank account that offers a 0.60% APY then you can expect to make $5,000 times .006 …


I recently just completed the first couple of lessons of Jeremy Howard’s new fastai course (https://course.fast.ai/) where he shows how you can develop a powerful image classification deep learning neural network web application with the popular package. While he does an excellent job of going through the steps, there are always going to be some aspects that don’t exactly work as advertised, either due to having become outdated since the original publication or simply due to working in a different environment. …


As COVID-19 spreads across the globe, President Donald Trump has suggested that the virus will “go away” in April due to the warmer weather. The apparent reasoning behind that claim is that other respiratory viruses such as those that cause the common cold and seasonal flu tend to subside during the warmer months. Experts tend to agree that there is not yet any evidence suggesting that there is a seasonality to this particular strain of coronavirus known as SARS-CoV-2.
