Your Open-Source Client Options In The Non-Mastodon Fediverse

May 8, 2024 by Lewin Day 22 Comments

When things started getting iffy over at Twitter, Mastodon rose as a popular alternative to the traditional microblogging platfrom. In contrast to the walled gardens of other social media channels, it uses an open protocol that runs on distributed servers that loosely join together, forming the “Fediverse”.

The beauty of the Fediverse isn’t just in its server structure, though. It’s also in the variety of clients available for accessing the network. Where Twitter is now super-strict about which apps can hook into the network, the Fediverse welcomes all comers to the platform! And although Mastodon is certainly the largest player, it’s absolutely not the only elephant in the room.

Today, we’ll look at a bunch of alternative clients for the platform, ranging from mobile apps to web clients. They offer unique features and interfaces that cater to different user preferences and needs. We’ll look at the most notable examples—each of which brings a different flavor to your Fediverse experience.

Remembering Dick Rutan And His Non-Stop Flight Around The World

May 8, 2024 by Maya Posch 5 Comments

On December 23, 1986, an airplane landed at Edwards AFB. This by itself wouldn’t mean much, but this particular airplane had just written history. Piloted by Dick Rutan and Jeana Yeager, the Rutan Model 76 Voyager had just completed its non-stop flight around the world after taking off from that very same runway just over nine days prior. Designed by Dick’s younger brother Burt Rutan, this airplane and this one flight will forever speak to the world’s imagination, even as we say farewell to Dick “Killer” Rutan.

Born Richard Glenn Rutan on July 1, 1938, he spent his military career in the United States Air Force, initially working with radar systems before beginning pilot training in the 1960s. He flew 325 sorties over Vietnam (ejecting once) and served for many more years while racking up many awards and reached the rank of Lieutenant Colonel before retiring in 1978.

After this he would fly as a test pilot for a range of aircraft, including a modified Rutan Long-EZ: the XCOR EZ-Rocket in 2001. Yet no flight would be as memorable as the record-breaking flight in the Rutan Voyager, which saw the world’s media following the aircraft’s journey around the globe, including with live feeds whenever the aircraft was within reach of national broadcasters. Despite nine days of strenuous flight and some mechanical breakdowns and damaged wingtips (from the fuel-burdened wings scraping over the runway), the flight went about as well as could have been hoped, thanks to Dick’s and Jeana’s piloting skills.

Dick Rutan died on May 3, 2024 at the age of 85 after a long struggle with the consequences of Long COVID. He will be sorely missed by the aviation community and countless others, but his achievements never forgotten.

3D Printed Fidget Knife Snaps Back And Forth All Day Long

May 8, 2024 by Donald Papp 31 Comments

Fidget toys all have a satisfying mechanical action to engage with, and [uhltimate]’s OTF (out the front) “fidget knife” model provides that in spades. The model snaps open and closed thanks to a clever arrangement of springs and latches contained in only three printed pieces.

Here’s how it works: at rest, the mock blade (orange in the image above) is latched in the closed position. As one presses the slider forward, the bottom spring begins to pull up against the blade until it moves far enough to release the latch. When the latch is released, the tension built up in the spring propels the blade outward where it again latches in the open position. Retraction is the same essential process, just in the opposite direction (and using a latch on the opposite side of the blade, which faces the other direction.)

As you may imagine, effective operation depends on the material. The model is designed to be printed in PLA, but [uhltimate] also provides a part variation with a stiffer spring for those who find that basic model isn’t quite up to the task for whatever reason. Smooth surfaces are also helpful for hitch-free operation, but lubrication shouldn’t be necessary.

If this sort of thing is up your alley, don’t miss the satisfying snap action of this 3D printed toggle mechanism, either!
