Reviewing year 4 of paulvanderlaken.com

Reviewing year 4 of paulvanderlaken.com

Despite the pandemic, 2020 has been a great year for me.

Professionally, I grew into my role as data science product owner. And next to this, I got more and more freelance side gigs. Mostly teaching, but also some consultancy projects. Unfortunately, all my start-up ideas failed miserably again this year, yet I’ll keep trying : )

Personally, 2020 was also generous to us. We have a family expansion coming in 2021! (Un)Fortunately, the whole quarantaine situation provided a lot of time to make our house baby-ready!

A year in numbers

2020 was also a great year for our blog.

Here are some statistics. We reached 300 followers, on the last day of the year! Who could have imagined that?!

per post0,420,8297%
per post1,211,19-1%

This tremendous growth of the website is despite me posting a lot less frequently this year.

After a friend’s advice, I started posting less, but more regularly.

Can you spot the pattern in my 2020 posting behavior?

Compare that to my erratic 2019 posting:

Now my readers have got something to look forward to every Tuesday!

Yet, is Tuesday really the best day for me to post my stuff?

You seem to prefer visiting my blog on Wednesdays.

Let me know what you think in the comments!

I am looking forward to what 2021 has in store for my blogging. I guess a baby will result in even less posts… But we’ll just focus on quality over quantity!

I hope I can keep up with the exponential growth:

Best new articles in 2020

There are many ways in which you could define the quality of an article.

For me, the most obvious would be to look at some view-based metric. Something like the number of views, or the number of unique visitors.

Yet, some articles have been online longer than others. So maybe we should focus on the average views per day. Still these you can expect to be increase as articles have been in existance longer.

In my opinion, how an article attract viewers over time tells an interesting story. For instance, how stable are the daily viewer numbers? Are they rising? This is often indicative that external websites link to my article. Which implies it holds valuable information to a specific readership. In turn, this suggests that the article is likely to continue attracting viewers in the future.

Here is an abstract visualization. Every line represents and article. Every line/article starts in the lower left corner. On the x-axis you see the number of days since posting. So lines slowly move right, the longer they have been on my website. On the y-axis you see the total viewers it attracted.

You can see three types of blog articles: (1) articles that attract 90% of their views within the first month, (2) articles that generate a steady flow of visitors, (3) articles that never attract (m)any readers.

Here’s a different way of visualizing those same articles: by their average daily visitors (x) and the standard deviation in daily visitors (y).

Basically, I hope to write articles that get many daily visitors (high x). Yet, I also hope that my articles have either have stable (or preferably increasing) visitor numbers. This would mean that they either score low on y, or that y increases over time.

By these measures, my best articles of 2020 are, in my opinion:

  1. Bayesian statistics using R, Python, & Stan
  2. Automatically create perfect .gitignore file
  3. Create a publication-ready correlation matrix
  4. Simulating and visualizing the Monthy Hall problem in R & Python
  5. How most statistical tests are linear

Best all time reads

For the first time, my blog roll & archives were the most visited page of my website this year! A whopping 13k views!!

With regard to the most visited pages of this year, not much has changed since 2019. We see some golden oldies and I once again conclude that my viewership remains mostly R-based:

  1. R resources
  2. New to R?
  3. R tips and tricks
  4. The house always wins
  5. Simple correlation analysis in R
  6. Visualization innovations
  7. Beating battleships with algorithms and AI
  8. Regular expressions in R
  9. Learn project-based programming
  10. Simpson’s paradox

A new blog post every Tuesday!

A new blog post every Tuesday!

Hi dear readers!

I’ve been blogging for just over three years now. Writing my first blogs in January 2017 in a small café in London out of pastime, I had never imagined that I would actually attract a readership. And while my blog grew in visitors and followers, it always remained just a hobby for me to summarize and post stuff I was reading or working on at the time.

Still, I want to make sure that you — my readership — get the most out of the time I invest in my blogs. Some blogs are more interesting than others, I am aware. However, I notice that it’s not only the content, but also the time and momentum of posting that draws in you readers.

Hence, I propose the following: Rather than erratically posting everything at the time of writing, I’m going to provide you with some regularity. As of today…

I will post a new blog every Tuesday, at 15:00 GMT+1

“Why that specific time?” I hear you asking. Well, it’s the perfect time as all my followers are still awake on the same day!

  • My Asian followers can read the blog just before or in bed,
  • My African and European readers can look forward to their commute home, and
  • My North- and South-American fans can enjoy it with their morning coffee!

Over the course of last year, I posted nearly 100 blogs. If you do some quick maths, you will conclude that 1 post every Tuesday is a lot less.

And this is where you come in:

Please let me know at what time you would prefer to have me post a second blog every (other) week. You can do so in the comments, by sending me a direct message, or by reaching out to me on twitter or LinkedIn.

Top-19 articles of 2019

Top-19 articles of 2019

With only one day remaining in 2019, let’s review the year. 2019 was my third year of blogging and it went by even quicker than the previous two!

Personally, it has been a busy year for me: I started a new job, increased my speaking and teaching activities, bought and moved to my new house, and got married op top of that!

Fortunately, I also started working parttime. This way, I could still reserve some time for learning and sharing my learnings. And sharing I did:

I posted 95 blogs in 2019!
That means one new post every 4 days!

paulvanderlaken.com improved its online footprint as well. We received over 100k visitors in 2019! And many of you subscribed and sticked around. Our little community now includes 55 more members than it did last year! And that is not even including the followers to my new twitter bot Artificial Stupidity!

Thank you for your continued interest!

Now, I am always curious as to what brings you to my website, so let’s have a look at some 2019 statistics (which I downloaded via my new Python scraper).

Most read articles

There is clearly a power distribution in the quantity with which you read my blogs.

Some blogs consistently attract dozens of visitors each day. Others have only handful of visitors over the course of a year.

These are the 19 articles which were most read in 2019. Hyperlinks are included below the bar chart. It’s a nice combination of R programming, machine learning, HR-related materials, and some entertainment (games & gambling) in between.

Which have and haven’t you read?

  1. R resources
  2. R tips and tricks
  3. New to R?
  4. Books for the modern, data-driven HR professional
  5. The house always wins
  6. Visualization innovations
  7. Simple correlation analysis in R
  8. Beating battleships with algorithms and AI
  9. Regular expressions in R
  10. Simpson’s paradox
  11. Visualizing the k-means clustering algorithm
  12. Survival of the best fit
  13. Datasets to practice and learn data science
  14. Identifying dirty twitter bots
  15. Game of Thrones map
  16. Screeps
  17. Northstar
  18. The difference between DS, ML, and AI visualized
  19. Light GBM vs. XGBoost

Rising stars

Half of these most read articles have actually been published in 2017 or ’18 already. However, of the 95 articles published in 2019, some also demonstrate promising visitor patterns:

The People Analytics books, Visual innovations, and AI Battleships are in the top 19, and several others made it too.

Some of these newer blogs haven’t had the time to mature and redeem their place yet though. Regardless, I have high hopes!

Particularly for Neural Synesthesia, which was easily one of my greatest WOW-moments for ML applications in 2019. It’s truly mesmerizing to see a GAN traverse its latent space.

Reading & posting patterns

I have been posting quite regularly throughout the year. Apart from a holiday to Thailand during the start of January, and the start of my new job in February.

While I write and post most of my blogs in the weekend, I guess I should consider postponing publishing. As you guys are mostly active during Tuesdays and Wedsnesdays!

Statistical summary of 2019

What better way to end 2019 than with a statistical summary?

I have posted more and shorter blogs, and you’ve rewarded me with visits and more likes (also per post). However, we need more discussion!

2020 Outlook

It took some time to get started, but halfway 2017 my blog started attracting an audience. People stayed on during 2018, and visitor number continued to increase through 2019.

With an ongoing expansion from R into Python, and an increased focus on sharing resources, applications, and novelties related to data visualization and machine learning, I have a lot more in store for 2020!

I hope you stick around for the ride!

Please like, subscribe, share, and comment, and we’ll make sure 2020 will be at least as interesting and full of (machine) learning as 2019 has been!
