When Timm, Laura, Elber and I first ran the @everytreenyc Twitter bot almost a year ago, we knew that it wasn’t actually sampling from a list that included every street tree in New York City. The Parks Department’s 2015 Tree Census was a huge undertaking, and was not complete by the time they organized the Trees Count! Data Jam last June. There were large chunks of the city missing, particularly in Southern and Eastern Queens.
The bot software itself was not a bad job for a day’s work, but it was still a hasty patch job on top of Neil Freeman’s original Everylotbot code. I hadn’t updated the readme file to reflect the changed we had made. It was running on a server in the NYU Computer Science Department, which is currently my most precarious affiliation.
On April 28 I received an email from the Parks Department saying that the census was complete, and the final version had been uploaded to the NYC Open Data Portal. It seemed like a good opportunity to upgrade.
Over the past two weeks I’ve downloaded the final tree database, installed everything on Pythonanywhere, streamlined the code, added a function to deal with Pythonanywhere’s limited scheduler, and updated the readme file. People who follow the bot might have noticed a few extra tweets over the past couple of days as I did final testing, but I’ve removed the cron job at NYU, and @everytreenyc is now up and running in its new home, with the full database, a week ahead of its first birthday. Enjoy the dérive!
Since July 2016 I have been working as Associate Application Systems in the Teaching and Learning Applications group at Columbia University. I have developed several apps, including this Photo Roster, an LTI plugin to the Canvas Learning Management System.
This is the third generation of the Photo Roster tool at Columbia. The first generation, for the Prometheus LMS, was famously scraped by Mark Zuckerberg when he extended Facebook to Columbia. To prevent future release of private student information, this version uses SAML and OAuth2 to authenticate users and securely retrieve student information from the Canvas API, and Oracle SQL to store and retrieve the photo authorizations.
It would be a release of private student information if I showed you the Roster live, so I created a demo class with famous Columbia alumni, and used a screen recorder to make this demo video. Enjoy!
If you have an Android phone like me, you probably use Google Calendar. I like the way it integrates with my contacts so that I can schedule events with people. I like the idea of it integrating with my Google+ contacts to automatically create a calendar of birthdays that I don’t want to miss. There’s a glitch in that, but I’ve created a new app to get around it, called Selected Birthdays.
The glitch is that the builtin Birthdays calendar has three options: show your Google Contacts, show your contacts and the people in your Google+ circles, or nothing. I have a number of contacts who are attractive and successful people, but I’m sorry to say I have no interest in knowing when their birthdays are. Natasha Lomas has even stronger feelings.
Google doesn’t let you change the builtin Birthdays calendar, but it does let you create a new calendar and fill it with the birthdays that interest you. My new web app, Selected Birthdays, automates that process. It goes through your contacts, finds the ones who have shared their birthdays with you, and gives you a checklist. You decide whose birthdays to include, and Select Birthdays will create a new calendar with those birthdays. It’ll also give you the option of hiding Google’s built-in birthday calendar.
For the app to work you’ll have to authorize it to read your contacts and write your calendars. For your privacy, the app communicates directly between your browser and Google’s server; once you download it there is no further contact with my server. There is no way for me to see or edit your contacts or calendars. You can verify that in the source code.
Please let me know if you have any comments, questions or suggestions. I have also made the code available on GitHub for free under the Apache License, if you want to build on it. A number of people have said they wish they had an app like this for Facebook. If enough of you repeat that, I’ll look into it!
