From Parklane Landscapes

Shifting Baseline Syndrome (SBS) is what happens when we forget how vibrant the natural world used to be. Each generation grows up with a more depleted environment and calls it "normal," simply because it's all they've ever known.

Think about walking through a park and thinking, "This seems healthy." But maybe 30 years ago that same park had twice as many birds, wildflowers, or insects. If you never saw that version, you don't feel the loss - and that quiet forgetting becomes the new baseline. Over time, we start accepting degraded ecosystems as normal.

Researchers warn that this shift lowers our expectations, increases our tolerance for decline, and reduces our urgency to protect what's left.

What helps:

Intergenerational conversations that reconnect us with what nature used to be.

Direct experiences with nature that sharpen our awareness of change.

Remembering (knowing) the past is the first step to restoring the future.

Not a sponsor, I don't think it's an AI graphic, and I think it has something important to say. Plus it does have an owl. We can't save our animals if we don't save them the spaces they need to thrive.

French astrophysicist Jean-Pierre Luminet created the first-ever simulation of a black hole, published in Astronomy and Astrophysics. Using an IBM 7040 computer and hand-plotting techniques with India ink, he calculated how light from an accretion disk would be distorted by gravity, producing a "distorted eye" image remarkably similar to modern direct imaging

I bought it because I liked how it looks. It's ok to ride too, weighing only slightly more than Portugal. Needs a bit of tlc.

First Northern Hawk Owl sighting. It finally happened after a year of dreaming about them heavily. A short encounter, but it felt like my dreams came true! 😍

I sometimes try to capture wild life that is different than the ordinary. Very close to sunset I captured this photo of this little Great Horned Owlet that seems to be letting Mom and Dad know that it's hungry.

Hey there,

A few months ago we open sourced Voiden, an offline API client we originally built to replace Postman internally.

Voiden now has around 11k installs and growing every day. ❤️

Core principles we built it on:

  • free and local-first
  • file-based, all plain executable markdown
  • composable through blocks
  • collaboration in Git, where devs are working already

The main thing is that in Voiden, API requests are not (static) forms. They are built from blocks (endpoint, auth, params, body) that can be used, reused, replaced and version in Git, just like code. And all that in plain executable text.

Our inspiration:

Our inspiration was curl, and how simple it is, and obsidian, because of how powerful it can be.

Who this is for:

Developers, QA, Technical Writers working and collaborating on APIs.

Progress:

Since open sourcing, almost everything that we shipped came from actual users, feedback and contributions that pushed the tool in a few interesting directions. You can check our change-log here: https://voiden.md/changelog

A few highlights:

  • Composable API workflows: Voiden lets you build reusable .void files that can be combined into flows, run multiple requests in sequence, and use real scripting (JS/Python/Shell) before and after requests.
  • Added a “skills” layer so tools like Claude/Codex can operate directly on .void files and request blocks.
  • We added an SDK for community plugins.
  • & more...

Feedback:

This project is now mostly shaped and driven by community ideas and contributions. Welcome to join and help us make this even more awesome.

There is no account setup, its free and totally offline.

A novel ultra high-speed maglev transportation system under development recently passed a trial run in Datong, Shanxi province.

The successful demonstration test brings the train another step closer to market, where it could significantly reduce travel times and boost cross-regional economic exchanges.

With a maximum designed speed of 1,000 kilometers per hour, the T-flight system is about three times faster than current high-speed trains and even faster than airplanes. If put into operation, travel time between Beijing and Shanghai will be shortened to about an hour, a fraction of the time of the current fastest train trip between the metropolises — 4 hours and 18 minutes — and about half as long as a flight, which takes roughly two hours.

"As socioeconomic development continues, people's demand for faster, more comfortable transportation is increasing," said Zhao Ming, a technician from the Institute of Maglev and Electromagnetic Propulsion of China Aerospace Science and Industry Corp, which develops the train. "The T-flight will play a role in creating a 'one-hour economic circle' among core urban clusters in China, and together with high-speed rail, civil aviation and other modes of transportation, it will form a comprehensive three-dimensional transportation network in the country."

The train's ultra high speed is due to a low vacuum tube and magnetic levitation system, which enables it to achieve "near-ground flight" — a revolutionary technology, he said at the China (Taiyuan) International Energy Industry Expo 2024 in Taiyuan, Shanxi, on Wednesday.

By extracting air from the tube to create a low vacuum environment, the train can operate with minimal air resistance. At the same time, maglev technology ensures the train and the track keep from touching, further reducing frictional resistance. The combination of the vacuum and maglev technology increases the train's speed and also reduces noise and vibration, according to Zhao.

The superconductive maglev technology used in the project can elevate the train by 100 millimeters — compared with the 10 mm separation currently used in maglev trains operating in China — to increase speed and stability, he added.

Since its launch in September 2021, the project has made significant progress. During the recent test conducted in Yanggao county, Datong, once the project team established a low vacuum environment within a 2-km tube, the maglev train set off along the designed route, maintained stable levitation and safely came to a stop.

The maximum speed and levitation height met the preset values, all systems worked correctly, and the actual trajectory matched well with the theoretical one, meaning the experiment was successful, according to the company.
