Yes! I’ve tested something similar, but never finished it. For me, it was important to only consider posts with a certain upvote count. As for filtering, I wanted to be notified whenever words like „data visualisation“, „Berlin“, … are included.

I‘m really happy with Zed for many month now. After using Sublime Text many years, VS Code was too slow and my Intel Mac couldn’t handle it.

📣 NEW! I’ve just released the BIGGEST and perhaps most creative project I’ve ever worked on! “Searching for Birds” searchingforbirds.visualcinnamon.com 🐤 A project, an article, an exploration that dives into the data that connects humans with birds, by looking at how we search for birds.

Indeed, very well done. I find it interesting how many of the data visusalisation people are close together, but I’m somewhere far away between “German-Speaking-Left-Wing Creatives” and “German Digital Humanities Scholars”.

The optimist vs pessimist divide in #climate debates isn’t usually about the data. It’s about how the same graphs are read, what people emphasise, what they discount, and how they interpret pace and stakes. Here’s what I mean 🧵👇

In collaboration with Nature, I investigated the impact of the Trump administration on US science one year after its return to office. More than 7800 research grants were cancelled or frozen, affecting ~25000 scientists and research staff and resulting in an ~US$32 billion in lost research funding.

I agree with everything in your blog post. The idea behind the icons in the “Safari” menu *could be* to have one for items that can also be accessed via a shortcut, i.e. an important action. Except for “Services” and “Show all”. So it’s rather a vague theory.

I find those functionalities especially useful if the user can specifically filter the feed to their interests. miniflux.app lets you filter items by Regex, but I guess that’s not for everyone.

I would like to strengthen the idea to not limit RSS to blogs. Podcasts are a good example of this flexibility. In some projects, we have implemented feeds for new (data) releases, status changes and other listings.

Using all the different services is a bit of an overload, but in some locations the results are not that useful, so a fallback. For the temperature, I use the average in the end. I use Notion because I can add extra notes, such as the manually measured water temperature and duration, from my phone.

It also requests additional location information from Google Geocoder and 3geonames. All of this information is then put into a Notion table. The edge function then triggers a rebuild of the website. Meanwhile, the shortcut formats an SMS message to send to my partner.

Jonas Parnow @jonasparnow.com · 19/11/2025
I have an iOS shortcut that collects the user’s location and the current weather, and sends this information to a Netlify edge function. The function then uses the geolocation to request additional weather information from OpenMeteo and WeatherAPI.

Data visualizations are some of the most powerful tools in a climate science communicator’s playbook. However, designing visuals that are clear to the public and policy makers is not a straightforward task, writes @rachitdubey.bsky.social . So, what works?
