  1. All About Ken: Datatype is a variable font that turns text into tiny inline charts.. “Datatype, by Frank Tisellano, is a variable font that renders inline bar charts, sparklines, and pie charts straight out of OpenType ligatures. Write {b:30,70,50,90} and get {b:30,70,50,90}; no JavaScript, no SVG, no charting library involved.”

  2. About 20% of Taiwan’s population has Hakka ancestry or cultural roots. Around 38%, or roughly 1.8 million people, can speak Hakka.

    The strongest concentrations are in Hsinchu-Miaoli and parts of Kaohsiung-Pingtung.

  3. 44Net can bring network activity to life. Recently demonstrated at HAM RADIO, the interactive ARDC Globe uses 44Net to visualize activity across the network. What would you like to see visualized next? #44net #44yearsof44net #datavisualization #opensource #networking

  4. Hackaday: Track Bird Visitors With A Raspberry Pi And A USB Mic. “Avian Visitors is a lovely project by [Teddy Warner] that uses a Raspberry Pi and microphone to keep track of which birds have been visiting your home, and creates a colorful illustration of recent visitors on top of it all. It reports on a web interface of its own making, but what really takes things to a new level is an […]

  5. “It is good to have an end to journey toward; but it is the journey that matters in the end”*…

    Joseph Conrad’s Heart of Darkness

    C. J. Moran (peter-guillam123 on Github) maps the classics…

    The short version: PlotLines plays classic books as journeys, on maps of their own era… PlotLines takes out-of-copyright classics and draws their characters’ journeys on a period map. Pick a book, press play, and the whole cast moves at once – or follow one person and let the map travel with them. Hover any stop and you get the place as the text itself names it, with the line that puts them there.

    It began with Dracula, because Stoker wrote what is probably the best travel itinerary in Victorian fiction – a clerk crossing Europe by train, a ghost ship rounding Gibraltar with her captain lashed to the wheel, a three-pronged chase up a Romanian river at the end.

    There are forty-three books now, and they are no longer all novels, or all set in Europe. A walk at Hardy’s pace across Wessex; a single London day of near-misses; a raft the length of the Mississippi; a stolen dog’s road from a Californian orchard to the Klondike ice; a two-town comedy running between Tokyo and Shikoku; a 120-chapter Chinese epic that needs five threads moving at once before it makes any sense at all; and a family driven out of a Southern town that is never once named. The shelf has turned out wider than I expected when I started, and more will follow…

    Each book opens with a choice: watch the story or explore its places. A shelf of journeys: “PlotLines.”

    As we trace steps (and think about the ways in which travel has changed), we might recall that it was on this date in 1891 that The Hotel Hauffe in Leipzig, Germany became the first establishment to honor an American Express Travelers Cheque. Travelers cheques were first issued in 1772 by the London Credit Exchange Company for use in 90 European cities; and in 1874, Thomas Cook was issuing “circular notes” that operated in the manner of travelers cheques. But until the late 19th century, well-off travelers relied mostly on letters of credit… and less wealthy travelers risked carrying cash. American Express’ was the first system of significant scale and global scope, and offered cheques in relatively small denominations, making them available to many more travelers.

  6. Taiwan may be relatively small geographically, but its economy is comparable to those of the largest U.S. states.

    With a GDP of approximately US$920 billion in 2025, Taiwan had a larger economy than 42 U.S. states. Only California, Texas, New York, Florida, Illinois, Pennsylvania, Ohio, and Georgia ranked higher.

  7. Decided to have a bit of fun on the 🚄

    🌡️ Summer Heat Trends (1960–2025): Rome, Paris, London, Edinburgh

    🔥 Rome leads with avg. daytime temps rising from 27°C (1960) to 32°C (2025).

    Paris, London, and Edinburgh also show steady increases, with extreme highs climbing across all cities.

    And some people still think global warming doesn't exist??? 🥵🥵

    Rome: Climate-Data.org, Holiday-Weather
    Paris: Weather & Climate
    London: Met Office, Weather Spark
    Edinburgh: Introducing Edinburgh, AccuWeather

  8. 📊 Oh, the horror! Another "expert" discovers that averages might be lying to them. Who knew data visualization could be so tricky? 😱 But don't worry, they called in backup to confirm that, yes, latency problems are hard and noisy data is still, shockingly, noisy. 🤯🔍

  9. Gizmodo: This SimCity-Like Visualization Turns Tech’s Most Boring Systems Into Fun. “Look, no one has ever accused SQL of being fun. It’s ubiquitous, it’s important, and it’s probably something you need to understand if you’re going to be doing any sort of work with data analytics, web development, and any other field that involves, y’know, data. But fun? Not so much. But maybe […]
