How to get the most out of Python classes

There should only be one — and preferably only one — obvious way to do it”, says the Zen of Python. Yet there are areas where even seasoned programmers debate what the right or wrong way to do things is. One of these areas is Python classes. Borrowed from Object-Oriented Programming, they’re quite beautiful constructs that you can expand and modify as you code. The big problem is that classes can make your code more complicated than necessary, and make it harder to read and maintain. So when should you use classes, and when should you use standard functions instead?…

How gravitational forces stop Earth’s asymmetrical core from tipping us over

More than 5,000 kilometers beneath us, Earth’s solid metal inner core wasn’t discovered until 1936. Almost a century later, we’re still struggling to answer basic questions about when and how it first formed. These aren’t easy puzzles to solve. We can’t directly sample the inner core, so the key to unravelling its mysteries lies in collaboration between seismologists, who indirectly sample it with seismic waves, geodynamicists, who create models of its dynamics, and mineral physicists, who study the behavior of iron alloys at high pressures and temperatures. Combining these disciplines, scientists have delivered an important clue about what’s happening miles…

In the 50s and 60s both American and Soviet films were banned in Yugoslavia, so instead they imported films from Mexico, who were going through their cinematic golden age. This created a Mexican craze in Yugoslavia where Yugoslav singers would dress like mariachis, sing songs in a Mexican style.

In a separate complaint filed the same day, the Securities and Exchange Commission commented the following:  Milton sold a version of Nikola not as it was — an early-stage company with…

Google’s ‘time crystals’ could be the greatest scientific achievement of our lifetimes

Eureka! A research team featuring dozens of scientists working in partnership with Google‘s quantum computing labs may have created the world’s first time crystal inside a quantum computer. This is the kind of news that makes me want to jump up and do a happy dance. These scientists may have produced an entirely new phase of matter. I’m going to do my best to explain what that means and why I personally believe this is the most important scientific breakthrough in our lifetimes. However, for the sake of clarity, there’s two points I need to make first: Time crystals are a…

EU slaps Amazon with record $887M fine over ad targeting practices

The EU has fined Amazon a record €746 million ($887m) for GDPR violations related to ad targetting. The decision stems from a 2018 complaint by French privacy rights group La Quadrature du Net, which alleged that Amazon’s ad targetting doesn’t obtain free consent from users. The ruling, which was issued by Luxembourg’s data protection authority (CNPD) on July 16, was disclosed by Amazon in a regulatory filing on Friday. The CNPD oversees Amazon’s operations in Europe because the company’s EU headquarters are based in Luxembourg. The watchdog said that “Amazon’s processing of personal data did not comply with the EU General Data…

The age of the metaverse is upon us

The metaverse has become the hottest buzzword in tech. Silicon Valley big brains are suddenly obsessed with building virtual spaces spanning digital and physical domains.

How ‘Instagram therapy’ is helping women with mental health

Women make up the majority of people living with mood disorders in Canada. However, treatments and resources that are adapted to their needs are still lacking. Looking for ways to feel better, many women are turning to social media platforms like Instagram. To make sense of the phenomenon called “Instagram therapy,” I interviewed more than 20 women in 2020 who use Instagram for mental health care. I found that women turn to the image-sharing platform to counter the lack of available resources. Instagram allows them to tackle issues related to their gender identity, connect to others with similar experiences and,…
