Scientists in China have demonstrated a wireless power transmission system that uses a ground-based microwave emitter to beam energy to an antenna array mounted on the aircraft’s underside. Importantly, they were able to do this while both the drone and charging system were in motion.

In tests, the car-mounted system kept fixed-wing drones in the air for up to 3.1 hours at an altitude of 15 metres (49 feet). The key challenge that the team overcame was maintaining alignment between the emitter and the drone during flight, wrote Song Liwei, the project’s leader.

Hey everyone, I’m Daniel.

It's been 103 days since I last posted about Reitti, and what a journey it's been! What started as a personal project on June 5, 2025, has grown immensely. In that time, Reitti has seen exactly 52 releases, culminating last week in the biggest and most ambitious update yet: Reitti 4.0! Today, I want to recap everything that's happened since my last post.

The past few months have been dedicated to transforming how I interact with my movement data, and the community's support has been incredible:

• 1,979 Stars on GitHub.
• 467 Commits to main with 419 PRs merged.
• 374 Issues closed.
• 25 Contributors on GitHub.
• 13 Languages supported.

What is Reitti?

"Reitti" is Finnish for "route" or "path." It’s a personal location tracking and analysis application. It is fully local and private, and no data ever leaves your server. You own the database, and you own the memories.

Reitti 4.0: A New Map Experience

This release focuses on taking your map experience to the next level. I've completely rebuilt the map from the ground up, switching to a foundation powered by MapLibre GL JS and deck.gl. This enables a new level of visualization for your movements, even with millions of data points from years of tracking, it remains blazingly fast and responsive!

• Rewind & Replay Your Journeys: You can now watch your past movements unfold. This allows you to see how you moved through a specific day or trip.
• New Map Layers: I've added new map layers that enhance your data visualization:
  • Terrain Layer: See the elevation changes along your paths. This adds a new dimension to your movement data.
  • Globe Projection: Zoom out and view your entire journey across a 3D globe.
  • Satellite View: Get a real-world perspective with high-resolution satellite imagery.
  • 3D Buildings: In supported areas, watch your paths weave through 3D building models.
• The Aggregate View: This feature helps understand your routine. The new aggregate view condenses all your movement data into a 24-hour window, allowing you to visualize your typical movements. Ever wondered where you usually are at 8 PM, or what your most common morning commute looks like?
• Fast Performance for Years of Data: Displaying multiple years of movement data used to be a challenge. Not anymore! Reitti 4.0 has been heavily optimized to handle vast amounts of historical data without breaking a sweat, ensuring a smooth and responsive experience even for the most avid trackers. The timeline will also see improvements in an upcoming release, as simply displaying all trips and visits for a given time range doesn't always yield meaningful information.
• Flexible Path Visualizations: Now you can choose between:
  • Raw Paths: See every single point as recorded.
  • Default Paths: My improved, cleaned-up path rendering.
  • Edge Bundling: A new option that reduces visual clutter by bundling nearby paths together, making trends and frequent routes easier to spot.

Other New Functionality

Expanded Language Support

Thanks to the incredible dedication of the community translators, Reitti has expanded its global reach and now officially supports more languages, including:

• ¡Hola! Spanish!
• こんにちは (Konnichiwa)! Japanese! (special thanks to @GunseiKPaseri!)
• Привіт (Pryvit)! Ukrainian!
• Merhaba! Turkish!

These additions are a huge step towards making Reitti accessible to even more users worldwide.

Place Editing with Geocoding

When editing a place, you can now directly request geocoding suggestions and select the most accurate result from various available providers. This makes managing your locations much more intuitive and precise.

Faster & More Robust Visit and Trip Detection

I've completely overhauled the algorithms for detecting visits and trips. The new system is not only significantly faster but also much more robust, leading to more accurate and reliable insights into your time spent and journeys taken.

New Dedicated Open-Source Services!

As part of this update, I'm introducing two new, free-to-use services that power Reitti 4.0 and are available for everyone:

• My Own Reverse Geocoder (Paikka): I've developed my very own reverse geocoder, free for everyone to use at https://geo.dedicatedcode.com/. You can find its source on GitHub (Paikka). This provides fast, reliable reverse geocoding directly from my infrastructure.
• My Own Tile Server: To complement the new map experience, I've also launched my own tile server at https://tiles.dedicatedcode.com/, based on the fantastic OpenFreeMap data. This ensures consistent, high-performance map tiles for all Reitti users.

BREAKING CHANGES – Please Read Carefully

While Reitti 4.0 added new features, there are a couple of crucial changes you need to be aware of for a smooth upgrade:

• rabbitmq has been fully removed. This simplifies the stack and reduces dependencies.
• photon has been removed from the default docker-compose file. While it's still supported if you wish to use it, it's no longer a default component thanks to my new open-source geocoding service!

It is absolutely essential that you update your docker-compose file during the upgrade process. Please visit https://www.dedicatedcode.com/projects/reitti/4.0/upgrade/ for the necessary steps to get your Reitti instance running seamlessly on 4.0.

Thank You

This project thrives because of its community. Thank you to everyone who contributed this year. To the new contributors like u/Jonsen94, u/GunseiKPaseri, u/sieren, u/wjansenw, u/subha0319, and u/per_terra your code, ideas, and dedication are invaluable. Special thanks go to the translators who ensure Reitti is accessible worldwide, and to everyone who posts issues, suggests features, and supports the project indirectly.

What’s Next?

Thanks to the incredible support from my Ko-fi supporters, I've recently acquired a dedicated GPS logger! This means I'm now setting my sights on bringing multi-device support to Reitti. Imagine this: you use your phone for day-to-day tracking, while simultaneously logging a run or ride with another device, leaving your phone at home. My goal is to seamlessly bring these timelines back together into one cohesive view. Along with this, I'll be introducing more powerful editing capabilities, such as defining "no-visit" areas and the ability to remove individual GPS points.

For the Memories feature I explored local AI for natural-language travel diaries, it's still very much on my mind. However, I haven't yet managed to get decent results with a small, local LLM that supports multiple languages. Time will tell if this ever happens, as I only want to introduce massive new requirements when they can deliver a truly tremendous impact for all of you. If anyone has a tip, please drop me a message.

Development Transparency

I use AI as a development tool to accelerate certain aspects of the coding process, but all code is carefully reviewed, tested, and intentionally designed. AI helps with boilerplate generation and problem-solving, but the architecture, logic, and quality standards remain entirely human-driven.

I appreciate your feedback and support! Here are a few ways to connect:

• Support My Work: If you find this project useful, you can support my efforts by buying me a coffee on Ko-fi.
• Report Issues: Encountered a bug? Open an issue on GitHub Issues.

Spoiler

Schrödinger's cat.

On April 17, engineers at NASA’s Jet Propulsion Laboratory (JPL) in Southern California sent commands to shut down an instrument aboard Voyager 1 called the Low-energy Charged Particles experiment, or LECP. The nuclear-powered spacecraft is running low on power, and turning off the LECP is considered the best way to keep humanity’s first interstellar explorer going.

...The instrument has provided critical data about the structure of the interstellar medium, detecting pressure fronts and regions of varying particle density in the space beyond our heliosphere. The twin Voyagers are the only spacecraft that are far enough from Earth to provide this information.

...“Voyager 1 still has two remaining operating science instruments — one that listens to plasma waves and one that measures magnetic fields. They are still working great, sending back data from a region of space no other human-made craft has ever explored...

Engineers are confident that shutting down the LECP will give Voyager 1 about a year of breathing room. They are using the time to finalize a more ambitious energy-saving fix for both Voyagers they call “the Big Bang,” which is designed to further extend Voyager operations. The idea is to swap out a group of powered devices all at once — hence the nickname — turning some things off and replacing them with lower-power alternatives to keep the spacecraft warm enough to continue gathering science data.

So, we have finally came to a point where the things are again spicing up. Many people are currently making fun of US for blockading a strait that is already blocked, it is funny yes, but it is also effective.

So we all know, there is currently a ceasefire between them, and US during this time has blockaded strait of hormuz, not allowing Iranian vessels to pass to Iranian ports, which forced Iran to reverse its decision to open strait of Hormuz.

Why is it clever? If Iran retaliates before or after the end of ceasefire in April 22nd, then US will shout to the world "Look, they attacked first" and then would have a viable reason to attack. If Iran does not attack, then it will be as if getting choked in your own home by an external power, eventually getting overpowered in your own area.

What I am saying, is that in any of the cases, if US has decided for a ground invasion, then yes, it it s inevitable, however things will be completely different if US lifts the blockade, which does not seem to happening.

The best thing Iran can do, they can lift the blockade from their side and give an ultimatum to US to do the reciprocal by any due date, failing to which it would re-block the strait. This way, atleast Iran will have the moral higher ground and will not be termed as the "escalator" in this conflict. Though conflict will still be inevitable. Thats my view. What do you think? Let me know.

This is it, the moment we have been waiting, today is the 28th anniversary of The Boondocks' syndication.

I have done some more digging into the history of the strip, and I found the FAQ from Aaron's old website.

For those unfamiliar, I have, with the help of other internet sleuths, uncovered the pre-syndicated Boondocks strips that were published in The Diamondback college newspaper. I also found two of the three spreads printed in Source Magazine.

If you are a fan of The Boondocks the strip, or the tv show, come join us to see how it all started.
