Python’s creator thinks it has a diversity problem — Quartz
▻https://qz.com/1624252/pythons-creator-thinks-it-has-a-diversity-problemIn a rare interview with the programmer in October last year, which was recently published on YouTube, he was asked about the lack of diversity among the people working on open-source programming languages. He noted that it was an issue, and said that those who ignore it, because open-source projects are available for anyone to contribute, are not seeing the full picture.
“It’s not just joining a project that’s the problem, it’s staying in the project, which means you have to feel comfortable exchanging emails and code reviews… with people that you don’t know personally but you communicate frequently with online,” he said. Van Rossum thinks that these exchanges can be difficult for women because of unconscious bias and male-driven cultural norms within open-source communities.
“It’s not just about writing the code, but you have stand up for your code and defend your code, and there is a certain male attitude that is endemic in many projects where a woman would just not feel comfortable claiming that she is right,” he explained. “A guy who knows less than that woman might honestly believe [he is right], so they present a much more confident image.” In his experience, van Rossum sees incompetent men’s ideas gaining acceptance more often than merited because they are more forceful in how they present them.
Van Rossum believes that the different attitudes of women and men in programming communities is due to wider societal problems that we need to fix from the bottom up. “I’ve always felt that feminism was right and we need to change the whole society,” he said. In the meantime, he feels a responsibility to act in the places he has influence, like in the Python community.
He believes the key to making open-source communities more inclusive is establishing (and enforcing) codes of conduct and mentoring. Van Rossum says that he now mentors women and underrepresented minority programmers. “But white guys can forget it,” he said. “They are not the ones who need it most.” (In typical programmer speak, he calls mentoring a “completely distributed, democratic approach.”)
Rather, he thinks it’s important that men are educated about their biases. “[There are] some guys who are super defensive when you tell about this shit, but the majority of guys just don’t know any better,” he said. “The first time I heard the term unconscious bias was maybe five years ago and it was an eye opener.” It’s changed him, and he thinks it could change others.

#python is First Step to Data Science
▻https://hackernoon.com/python-is-first-step-to-data-science-705911ddf5a1?source=rss----3a8144eaThe steadily increasing importance of data science across industries has led to a rapid demand for data scientists. It’s been said that the role of data scientist is the 21st century’s sexiest job title. If you wonder why it has become such a sought after position these days, the short answer is that there has been a huge explosion in both data generated and captured by organizations and common people and data scientists are the people who derive valuable insights from that data and figure out what can be done with it.If you go through some job advertisements for data scientists, you’ll see that expertise in data science and Python are considered as two of the most crucial skills described.In this post, we’re going to discuss why these skills are considered must for data scientists.1- What (...)

But we really wanted to focus on courses, or video like courses on youtube.There are so many options, it can be nice to have a list of classes worth taking.We are going to start with the free data science options so you can decide whether or not you want to start investing more in courses.Tip : Coursera can make it seem like the only option is to purchase the course. But they do have an audit button on the very bottom. Now, if you appreciate Coursera, by all means, you should purchase their specialization, I am still uncertain how I feel about it.

Semantic Versioning 101
▻https://hackernoon.com/semantic-versioning-101-d2623083714b?source=rss----3a8144eabfe3---4Semantic Versioning 2.0.0 (semver.org) is a robust and elementary standard that encapsulates a wealth of information about the software you’re publishing or consuming.Open source veterans know and understand the importance of this standard. If you’ve run a project in long-term maintenance mode, you come to realize its power one way or another. Still, enthusiastic, fast-moving dev teams like to find ways around this standard. I’ve seen more than a few engineers decide to invent their own ideas around major, minor, and patch increments. Their rationale is rooted in aesthetics or their own release schedule.A key principleAside from the concise and complete information at semver.org, it is critical to understand:Semantic versioning is for your consumers.

Histogram Equalization in #python from Scratch
▻https://hackernoon.com/histogram-equalization-in-python-from-scratch-ebb9c8aa3f23?source=rss---Histogram Equalization is one of the fundamental tools in the image processing toolkit. It’s a technique for adjusting the pixel values in an image to enhance the contrast by making those intensities more equal across the board. Typically, the histogram of an image will have something close to a normal distribution, but equalization aims for a uniform distribution. In this article, we’re going to program a histogram equalizer in python from scratch. If you want to see the full code, I’ve included a link to a Jupyter notebook at the bottom of this article. Now, if you’re ready, let’s dive in!Before anything, we have to do some setup. Let’s import the libraries we’ll be using throughout the program, load in the image, and display (...)
