The Allan I Carswell Observatory presents a new LIVE online event to celebrate the Mars Perseverance Landing this Feb 18, 2021 from 2:30–4:00pm EST (Toronto local time)!

In 2020 several Mars-bound rockets blasted off from the surface of Earth. Now in 2021 they are all arriving! Join our ‘Landing Party’ on Feb 18 to watch the Perseverance landing, learn about Mars and hear a live discussion of the final ‘7 minutes of terror’. Together, we will see if the Perseverance rover and Ingenuity helicopter safely make it to the surface.

This February is full of exciting missions. The United Arab…


TORONTO, ON, CANADA — York University Allan I. Carswell Observatory

Toronto’s Easter eggs in the sky: When thinking of searching for hidden things, most astronomers will quickly point to their favourite items up in the sky. Some of them have been true ‘Easter Eggs’, surprising and inspiring us all. Others we can still see up in the sky for the next week or so!


As an incoming professor at York University (Faculty of Science) in Toronto, I will be teaching in Physics and Astronomy. To celebrate the new on-campus telescope that was recently installed, and of course as an almost Canadian resident… I thought what better way to get started than to write about the data science of astronomy, the astronomy of telescopes, and how they can work together to help with furthering our knowledge of both. So let’s start!

A new telescope and the why of it all

As with any new endeavour, I will start with a question and work from there. How can I use the fabulous new campus telescope…


This story is adapted from my Twitter thread @astrohyde on July 21st 2019, for easier reading and perusal. The Apollo 11 Moon landing meant a great deal to many people, but for one square-dancer from Oregon, it was simply an important event, to remember and save. Monday July 21, 1969 The Oregonian newspaper published a special moon landing issue.


This holiday season, why not celebrate with a little cloud fun? Are you a Google great, and amazing Amazon, an awesome Azure… or maybe you just want to show them all how it’s done! Here is your chance to rain supreme in cloud knowledge, and have a bit of fun this holiday to boot. I have collected an assortment of holiday and other cloud type questions (and riddles) from many, many sources and put them here for all the crossword and cloud computing fans.

When searching for puns…. the sky’s the limit really


Deployment of a model

Making a model on Google Cloud Platform can take many forms, but once it is deployed how secure is it really? There are some huge advantages to using the security in place on GCP but there are a few things that Servian always does to address security and privacy concerns.

An example game App Security on GCP

Say for example, that I have a game that uses a trained machine learning algorithm to provide the user with real time weather data, such that the game weather reflects the weather where they are.

App Engine

Our example application will be deployed to App Engine. Datalab is used for the development…

The Google Cloud Platform (GCP) has been making waves recently with great new tools in Machine Learning (ML) and Analytics. What can we do to test these tools and investigate their capacity? Which is better, Cloud Datalab or BigQuery ML (BQML)? Can we build a custom estimator that is not supported by Google’s Estimator API?

I investigated these two interesting tools provided by GCP for ML to see how they would perform on the sample Google Analytics dataset for BigQuery. This dataset contains Google Analytics 360 data from the Google Merchandise Store.


Have you ever wondered just how your favourite tech company was ‘really’ doing? Wanted to track the hashtags you create or someone else’s on Twitter? Well, it turns out there is an easy way you can get access and run some very powerful Natural Language Processing (NLP) with very little training for your machine learning algorithms. We are going to use Python but we can avoid the nltk package altogether!

So, how do we get started? Well, firstly let’s pick one of the most common problems on Twitter, negative comments and posts. How can we track negativity over time in…
