How I Got My Articles Featured on TDS

Here’s what worked for me, in case you’re interestedPhoto by Thought Catalog on Unsplash

I’m about a year and a half into writing articles on Medium and it has been a very fun journey for me. I get questions on LinkedIn about how I have gotten published on Towards Data Science and also how I have gained followers. Here is a summary of strategies that worked well for me:

Write to Help Others Understand/Write with Clarity

To me, this is the most important goal of technical writing. Most articles on TDS are technical in nature, so writing to help your readers understand your point is key.… Read more...

Super 8 Camera Brought Back To Life

The Super 8 camera, while a groundbreaking video recorder in its time, is borderline unusable now. Even if you can get film for it (and afford its often enormous price), it still only records on 8mm film which isn’t exactly the best quality of film around, not to mention that a good percentage of these cameras couldn’t even record audio. They were largely made obsolete by camcorders in the late ’80s and early ’90s, although some are still used for niche artistic purposes. If you’d rather not foot the bill for the film, though, you can still put one of these to work with the help of a Raspberry Pi.… Read more...

Expanding On The Creation Of Collapsible Containers

You might remember that industrial designer [Eric Strebel] tried to make a collapsible silicone container with 3D printed molds a few weeks ago, and was finally successful after dozens of attempts. Someone commented that commercial containers are molded in the collapsed position instead of the expanded position, so naturally, [Eric] had to try it once he saw the photographic proof of these molds.

This time around, [Eric] made things easier on himself by adding some handles to the mold and using both wax and spray mold release before pouring in the degassed silicone. The first one was a failure —  he had let it cure the whole time in the collapsed mold, and it just didn’t want to stay expanded.… Read more...

Are we alone in the universe? — Data Analysis and Data Visualization of UFO sightings with R

How to analyze and visualize data of UFO sightings of the last century in the USA and the rest of the worldDashboard to see the generated plots about UFO Sightings. The link at the end of the article

One of the questions that human beings can ask themselves is whether we are alone in the universe. I think it would be ridiculous and extremely vain to assume that we are the only civilization with enough intelligence to visit other worlds in the universe. What if other civilizations more intelligent than us have already visited us? What if they are watching us right now?… Read more...

From Prototype to Production for Data Scientists

Bringing ideas and models to production for data scientists

You might be thinking “yeah, I know what a prototype is, what else is there to know?” You might be right, but do you know some of the different methodologies and terminology? These reduce friction when you’re trying to implement something new. Do you know the difference between an ‘evolutionary’ and a ‘throwaway’ prototype? Do you know what a rollout is? Do you know the pitfalls of doing a pilot? If so, maybe you can skip this article. If not, then understanding these concepts could help your company.

Note that prototype and pilot are used synonymously throughout this article.… Read more...

MicroSynth Mixes All-Analog Fun With A Little Business

While [MicroKits]’ MicroSynth is an all-analog synthesizer that fits on a business card-sized PCB, and he actually does use it to break the ice in business meetings, that’s not really the idea behind this project. Rather, [MicroKits] is keen to get people playing with synths, and what better way than a synth you can build yourself?

There was an ulterior motive behind this project, too: prototyping circuits for a more complete synthesizer. Thus, the design is purposely very simple — no microcontrollers, no logic chips, and not even a 555 to be found. It doesn’t even have buttons; instead, the one-octave keyboard just has interdigitated traces that are bridged by the player’s fingers, forming resistive touchpads.… Read more...

NASA Sets Eyes On Deep Space With Admin Shuffle

Since the Apollo 17 crew returned from the Moon in 1972, human spaceflight has been limited to low Earth orbit (LEO). Whether they were aboard Skylab, Mir, the Space Shuttle, a Soyuz capsule, or the International Space Station, no crew has traveled more than 600 kilometers (372 miles) or so from the Earth’s surface in nearly 50 years. Representatives of the world’s space organizations would say they have been using Earth orbit as a testing ground for the technology that will be needed for more distant missions, but those critical of our seemingly stagnated progress into the solar system would say we’ve simply been stuck.… Read more...

How to Determine the Best Fitting Data Distribution Using Python – KDnuggets

Sometimes you know the best fitting distribution, or probability density function, of your data prior to analysis; more often, you do not. Approaches to data sampling, modeling, and analysis can vary based on the distribution of your data, and so determining the best fit theoretical distribution can be an essential step in your data exploration process.

This is where distfit comes in.

distfit is a python package for probability density fitting across 89 univariate distributions to non-censored data by residual sum of squares (RSS), and hypothesis testing. Probability density fitting is the fitting of a probability distribution to a series of data concerning the repeated measurement of a variable phenomenon.… Read more...

Make This Halloween A Spider-Stomping Good Time

We can count on one hand the number of times that we haven’t needed a coat on Halloween night around here. Even if it was fair and sunny the day before, you can count on Halloween being appropriately windy, cold, and spooky. Trick-or-treating only keeps a kid so warm, and we would have loved to happen upon a house with a spider-stomping sugar-burning good time of a game going on in the driveway.

[Kyle Maas] built this game a few years ago, and it has proved quite popular ever since. It’s so popular, in fact, that they have to have someone on duty with a vaudeville hook to yank spectators off the playing field.… Read more...

Why Trust Matters in AI

We can all agree that AI has the potential to help businesses, organizations, and society solve real problems. But there are still many concerns about the consequences of using AI improperly. Things like ethics, privacy, bias, and security are top of mind. In order for AI projects to be fully embraced, companies must address these concerns, because people need to trust their AI in order for projects to be successful. In this installment of our blog post series, we will explore the question of why trust is an essential component to any conversation around AI.

Performance, Operations, and Ethics

Trust in AI is multidimensional.…

A Novel Framework for Reputation-Based Systems

Reputation systems present an opportunity for platforms to recognize—and thus incentivize—participants’ high-quality contributions, including content creation, moderation, community building, and gameplay. This is crucial to the growth and sustainability of any web3 project. Yet designing reputation systems requires complex considerations around reputation supply, distribution, credibility, and more. So while many are exploring this space—from DAOs like FWB to play-to-earn games like…… Read more...

Spark Troubleshooting, Part 1 – Ten Challenges

“The most difficult thing is finding out why your job is failing, which parameters to change. Most of the time, it’s OOM errors…” Jagat Singh, Quora

Spark has become one of the most important tools for processing data – especially non-relational  data – and deriving value from it. And Spark serves as a platform for the creation and delivery of analytics, AI, and machine learning applications, among others. But troubleshooting Spark applications is hard – and we’re here to help.

In this blog post, we’ll describe ten challenges that arise frequently in troubleshooting Spark applications. We’ll start with issues at the job level, encountered by most people on the data team – operations people/administrators, data engineers, and data scientists, as well as analysts.… Read more...

The Coming Copper Shortage: Aluminium Or Carbon Nanotubes To The Rescue?

The use of aluminium in wiring is unlikely to bring a smile to the face of anyone who has had to deal with it in a 1960s, or early 1970s-era house. The causes behind the fires and other accidents were myriad, including failure to deal with the higher thermal expansion of aluminium, the electrically insulating nature of aluminium oxide, and the general brittleness of aluminium when twisted.

Yet while copper is superior to aluminium in terms of electrical conductivity and ease of installation, copper prices have skyrocketed since the 1970s, and are on the verge of taking off to the moon.… Read more...
