This project (the website) is exactly that — Analytical challenges I encountered in work that required solutions with SQL. For each challenge I provide the questions, data that can be locally created, the solutions and a video I recorded going over the answer. https://www.amitgrinson.com/projects/sql-questions/ Tue, 05 Sep 2023 00:00:00 +0000 https://www.amitgrinson.com/projects/sql-questions/ Project Overview As a Data Analyst who writes a lot of SQL, I find myself coming across challenges I solved that I’d love to share with others.

Until I pick it up more seriously, here are two websites I built that I’m pretty fond of: Milo’s website A website I created for my dog. milo-the-dog.amitgrinson.com My Sister’s Cake Collection My sister makes lots of delicious cakes. When someone has an occasion the common question she raises is ‘what cake would you like? https://www.amitgrinson.com/talk/tlv-summit-portfolio/ Wed, 14 Sep 2022 00:00:00 +0000 https://www.amitgrinson.com/talk/tlv-summit-portfolio/ Abstract A personal portfolio can be a great resource to show your skills, especially when coming from a non-traditional background. But starting off with no real purpose you don’t necessarily treat it as a portfolio; rather just a place to hold your endeavors as you explore your curiosity. In this talk I hope to share a few takeaways from creating an unconventional portfolio as I went into data analytics. https://www.amitgrinson.com/blog/regex-in-sql/ Mon, 29 Aug 2022 00:00:00 +0000 https://www.amitgrinson.com/blog/regex-in-sql/ Going over various cases of text operations in a data analysis flow, showing how to solve it with R/Python compared to SQL. https://www.amitgrinson.com/blog/isvis-talk-post/ Tue, 28 Jun 2022 00:00:00 +0000 https://www.amitgrinson.com/blog/isvis-talk-post/ Summarizing the things I love about and learned from data visualization challenges as part of a talk I gave at the Israeli visualization conference, 2022. https://www.amitgrinson.com/blog/r-and-python/ Thu, 02 Jun 2022 00:00:00 +0000 https://www.amitgrinson.com/blog/r-and-python/ Using both R and Python we answer various questions about the Dog of Zurich dataset.

You can also find a summary I wrote here Abstract Many community visualization challenges can be found online today: Events targeting specific tools – the #TidyTeusday project, #MakeOverMonday – and other tool agnostic challenges such as the 30daychartchallenge and 30daymapchallenge. They’re open to anyone and everyone, beginners and advanced alike. In some challenges you bring your own data – an old dataset you had laying around or something you’ve been wanting to explore for a while – while in other challenges the data is provided by the organizers. https://www.amitgrinson.com/blog/review-of-an-sql-interview-question/ Tue, 31 Aug 2021 00:00:00 +0000 https://www.amitgrinson.com/blog/review-of-an-sql-interview-question/ Solving an SQL interview question using three different approaches. https://www.amitgrinson.com/talk/learning-gis-with-ice-creams/ Wed, 09 Jun 2021 00:00:00 +0000 https://www.amitgrinson.com/talk/learning-gis-with-ice-creams/ Before coming across R I never thought I’d manipulate spatial data. I started my R journey intending to analyze my thesis survey and discovered a plethora of analytic possibilities, one of them being spatial data. After fiddling around and creating some simple maps, I realized I had to dig deeper into R’s spatial capabilities. In this talk I outline my journey of learning how to work with spatial data from a former blog post of mine. https://www.amitgrinson.com/projects/israeli-twitter-bot/ Mon, 31 May 2021 00:00:00 +0000 https://www.amitgrinson.com/projects/israeli-twitter-bot/ Why the Pi After some recent learning of automating workflows with GitHub Actions, I wanted to take automating one step further. In January 2021 I bought myself a Raspberry Pi 4 (a small computer) and was pondering what to do with it. At the time Israel was preparing for its fourth consecutive election and I decided to create a corresponding Twitter bot that will operate on the Raspberry Pi. https://www.amitgrinson.com/blog/exploring-ice-cream-locations/ Wed, 10 Feb 2021 00:00:00 +0000 https://www.amitgrinson.com/blog/exploring-ice-cream-locations/ Exploring maps and distances to various Golda ice-cream locations throughout Israel https://www.amitgrinson.com/blog/automated-plot-with-github-actions/ Sun, 03 Jan 2021 00:00:00 +0000 https://www.amitgrinson.com/blog/automated-plot-with-github-actions/ a light introduction to GitHub Actions for automating a plot of frequently used R packages. https://www.amitgrinson.com/blog/my-year-in-r/ Thu, 15 Oct 2020 00:00:00 +0000 https://www.amitgrinson.com/blog/my-year-in-r/ Looking back at my year of learning R https://www.amitgrinson.com/blog/printing-survey-table/ Tue, 01 Sep 2020 00:00:00 +0000 https://www.amitgrinson.com/blog/printing-survey-table/ Aestheticaly printing descriptive variables from your survey data https://www.amitgrinson.com/blog/uncertainty-in-the-israeli-lottery/ Thu, 09 Jul 2020 00:00:00 +0000 https://www.amitgrinson.com/blog/uncertainty-in-the-israeli-lottery/ Exploring the probability of winning the lottery at and by a given trial with the Geometric distribution https://www.amitgrinson.com/blog/learning-tfidf-with-political-theorists/ Sun, 31 May 2020 00:00:00 +0000 https://www.amitgrinson.com/blog/learning-tfidf-with-political-theorists/ Learning tf-idf through political theorists. https://www.amitgrinson.com/blog/sharing-interactive-charts/ Fri, 01 May 2020 00:00:00 +0000 https://www.amitgrinson.com/blog/sharing-interactive-charts/ A walk through for sharing your interactive visualizations on GitHub Pages https://www.amitgrinson.com/blog/israeli-elections-on-twitter/ Mon, 20 Apr 2020 00:00:00 +0000 https://www.amitgrinson.com/blog/israeli-elections-on-twitter/ Analyzing tweets from the the Israeli elections week https://www.amitgrinson.com/talk/israel-2050/ Tue, 14 Apr 2020 00:00:00 +0000 https://www.amitgrinson.com/talk/israel-2050/ Brief talk about what is it I love about R. https://www.amitgrinson.com/blog/update-exam-grades-easy-with-r/ Sat, 15 Feb 2020 00:00:00 +0000 https://www.amitgrinson.com/blog/update-exam-grades-easy-with-r/ In this post I discuss my use of the xlsx and clipr packages for optimizing how I updated students exams https://www.amitgrinson.com/blog/eliud-kichoge/ Fri, 07 Feb 2020 00:00:00 +0000 https://www.amitgrinson.com/blog/eliud-kichoge/ In this post I plot Eliud Kichoge new marathon record using rvest to get data from wikipedia and ggimage for plotting images as points https://www.amitgrinson.com/blog/bomb-shelters/ Tue, 14 Jan 2020 00:00:00 +0000 https://www.amitgrinson.com/blog/bomb-shelters/ While rockets were fired towards Israel I decided to take the opportunity and plot bomb shelters in Beer-Sheva. https://www.amitgrinson.com/more_info/ Mon, 01 Jan 0001 00:00:00 +0000 https://www.amitgrinson.com/more_info/ Glad you’re here at this page.
