The Bluesky and ATmosphere reports are back after I was occupied last week with the Ahoy! conference about ATProto in Hamburg. It was amazing to meet so many cool people in real life, and share the excitement of working on this network together. There were some great talks, and just being around people who you can talk in-depth about Bluesky and ATProto with is just great. Hoping to see many more ATProto conferences pop up and meet more of you in real life.
A practical note: if you missed the ATmosphere report last week, a reminder that I’m also sending out the reports via email every Friday. This comes with an extra analysis article that’s not on the website, so don’t forget to subscribe!
Bluesky launches a blue check verification system
Bluesky has launched a new verification system for their platform, with blue checkmarks. With the checkmark system, Bluesky selects a few Trusted Verifiers, who can hand out checkmarks. Bluesky PBC will also hand out checkmarks to “authentic and notable accounts”. The main reason for this system’s existence is that the other verification system, using domain names as handles, did not perform well enough. Bluesky PBC says that 270k accounts have set their own domain name as a handle, but not enough high-profile accounts have done so. The other problem with domain names as verification is that many well-known public figures do not have a well-known website. The first organisations that are Trusted Verifiers in the Bluesky app are the New York Times and Wired Magazine.
Bluesky PBC advertises the new checkmark verification system with its Trusted Verifiers as “a healthy digital society should distribute power”. However, it is unclear with the current implementation to what extend power is actually distributed. Bluesky PBC is the one who selects the Trusted Verifiers that can be displayed in their app. In their blog post, they also write: “Bluesky will review these verifications as well to ensure authenticity.” To me, it seems far from distributing power, and can at best be seen as distributing operational work. With Bluesky PBC holding full control of who gets to be a Trusted Verifier, as well as reviewing their output, how much power has Bluesky PBC actually distributed?
The new checkmark verification system is not exclusive to the Bluesky app however, and it is build on an open system. Anyone can create verifications or become a Verifier, as all the data for verification is openly accessible to anyone. The only difference is that verifications that are not made by Bluesky PBC or one of their Trusted Verifiers will not be visible in the official Bluesky clients. Other systems have already sprung up, a new verifier tool by cred.blue allows anyone to easily hand out verifications. The Deer client, which is a fork of the Bluesky client, already allows for anyone to set their own Verifiers as well. I’ll talk more about this in an upcoming article, as what is happening with Deer and verification has some interesting implications on how the network will likely develop.
For now, Bluesky PBC has build a technologically cool system, which also solves a meaningful problem that their app has in the short term. While the way it is currently implemented falls short of the advertised distribution of power regarding verification, the team is clear that this is an early implementation and that the system will evolve later.
Streamplace funding
Some news from streaming software Streamplace:
Streamplace has raised 100k Livepeer tokens, worth around 500k USD, from the Livepeer Treasury to further expand the Streamplace platform. The money will be used to expand the team, enhance infrastructure and build a deeper integration with ATProto, as well as building content moderation infrastructure.
A short explanation of Livepeer, and how it relates to Streamplace. Livepeer is a decentralised network for video transcoding and processing. Transcoding (in this context) processes the video stream to make it accessible in various formats and qualities, so a stream can be viewed both by someone on a slow internet connection in 360p, as well as someone with fast internet in 4K definition. Livepeer is a DAO, with an attached crypto token. Streamplace uses Livepeer for the video transcoding, and because of this integration, which allows the Livepeer network to grow as well, the Livepeer DAO has awarded Streamplace 100k tokens, currently worth around 500k USD. It is unclear to me how the Livepeer token works, with its corresponding tokenomics, and where the value of the tokens is coming from.
Streamplace creator Eli Mellon gave an interview on the devtools-fm podcast where Eli goes into more detail on the background of Streamplace and how the software works.
Two other ATProto apps are working on integration Streamplace. Skylight already announced earlier to be working with Streamplace. At the ATProto conference Ahoy in Hamburg last week Joe Basser, co-founder of the ATProto video platform, announced to be working on livestreaming with Streamplace as well.

An update on relays and independent infra
Bluesky PBC made some changes to how their relays work, with an update with the unassuming name of ‘Sync 1.1′. The update made it much cheaper to run relays, as they do not have to store data of the entire network anymore. This has made a drastic impact on running relays. Last month, independent developer @futurset up a relay on his own Raspberry Pi. Now Phil, another independent developer, has set up multiple relays and made them publicly accessible. This means that there are now multiple other full-network relays that index the entire network, that are outside of US jurisdiction. Just as importantly, running these full-network relays is cheap, with costs getting as low as 18 USD per month. Feed builder Graze is also creating their own implementation of a relay: Turbostream includes a large amount of extra information in the stream. For example, where Jetstream (a simplified version of a relay) broadcasts a reply, Turbostream broadcasts a reply together with the post that is being replied to, as well as a range of other information. This in turn makes it easier to other parties to build on, as most information needed is already included in Turbostream.
These developments leads to some interested new questions. When it comes to running a relay, technology and costs are clearly not barriers anymore. But what about moderation and uptime guarantees? Is having a relay that many other parties depend on even the right model of the network?
It also calls the model that the Free Our Feeds campaign had in mind, which aligned more with a perspective of expensive and large relays. Today, Free Our Feeds announced that they will donate a 50k USD grant to a new IndieSky Working Group. The IndieSky came out of the second day of the conference, organised by Boris Mann and Ted Han. Mann and Han are behind the ATProtocol Developer Community Group, and also organised the first ATProto conference in Seattle last month. The goal of IndieSky is to “work together on R&D, code, and infrastructure on how and why to run different parts of the ATProto stack”, with more details in the announcement. The first meeting for the working group is on May 8th.

The Ahoy! conference for the European Social Web was last week, and as an extremely biased person who helped organise the conference I think it was a great success! Massive shout-out to Sebastian Korfmann who has done an incredible amount of work getting the conference to such a great place, super impressive. During the conference I did some longer video interviews with some of the people in the community, those videos will be released in the coming weeks. The main takeaway for me from the conference was to see the amount of positive energy and enthusiasm in the community. People are aware that they are contributing to a space that has massive potential and is undergoing rapid changes. I’m excited to see more conferences for ATProto, and meet more people from the community in real life, as it has been super great to meet the people at Ahoy!.
Turtleisland.social is a Mastodon server for the North American Native/Indigenous community. They have set up their own PDS server for community members to join Bluesky as well. Community-centered data hosting is one of the possibilities with the PDS system of Bluesky that is mentioned regularly as an option, but has not been borne out much yet. Two other communities are in the process of building out a similar structure: Blacksky is creating their own PDS software for the Black community, and Northsky is building out systems that allow people to easily migrate their ATProto account to a Northsky PDS. It’s worth pointing out here that the early adopters of new technology on social networking are all minority communities. For people building social networks this provides a pragmatic argument (besides the much more important ethical argument) for creating safe digital spaces: the people for whom safety is the most crucial are also the most likely to be early adopters of new technologies.
Not all early adoption is by minority communities: Gander.social is a newly announced social network on ATProto, focusing on the Canadian community. Gander has a lot of plans for features that make it stand out from the Bluesky app. The project is still in development, and it seems once the project gets closer to launch it will become clearer what the ATProto integration will actually entail.
Bluesky has made some changes to their PDS, allowing people to sign up directly for an ATProto account on a PDS without going through the Bluesky app. Link aggregator platform Frontpage is one of the first to take advantage of this, allowing account creation on the Frontpage platform now.

Brain-to-speech interfaces have been promising to help paralyzed individuals communicate for years. Unfortunately, many systems have had significant latency that has left them lacking somewhat in the practicality stakes.
A team of researchers across UC Berkeley and UC San Francisco has been working on the problem and made significant strides forward in capability. A new system developed by the team offers near-real-time speech—capturing brain signals and synthesizing intelligible audio faster than ever before.
New Capability
The aim of the work was to create more naturalistic speech using a brain implant and voice synthesizer. While this technology has been pursued previously, it faced serious issues around latency, with delays of around eight seconds to decode signals and produce an audible sentence. New techniques had to be developed to try and speed up the process to slash the delay between a user trying to “speak” and the hardware outputting the synthesized voice.
The implant developed by researchers is used to sample data from the speech sensorimotor cortex of the brain—the area that controls the mechanical hardware that makes speech: the face, vocal chords, and all the other associated body parts that help us vocalize. The implant captures signals via an electrode array surgically implanted into the brain itself. The data captured by the implant is then passed to an AI model which figures out how to turn that signal into the right audio output to create speech. “We are essentially intercepting signals where the thought is translated into articulation and in the middle of that motor control,” said Cheol Jun Cho, a Ph.D student at UC Berkeley. “So what we’re decoding is after a thought has happened, after we’ve decided what to say, after we’ve decided what words to use, and how to move our vocal-tract muscles.”
The AI model had to be trained to perform this role. This was achieved by having a subject, Ann, look at prompts and attempting to “speak ” the phrases. Ann has suffered from paralysis after a stroke which left her unable to speak. However, when she attempts to speak, relevant regions in her brain still lit up with activity, and sampling this enabled the AI to correlate certain brain activity to intended speech. Unfortunately, since Ann could no longer vocalize herself, there was no target audio for the AI to correlate the brain data with. Instead, researchers used a text-to-speech system to generate simulated target audio for the AI to match with the brain data during training. “We also used Ann’s pre-injury voice, so when we decode the output, it sounds more like her,” explains Cho. A recording of Ann speaking at her wedding provided source material to help personalize the speech synthesis to sound more like her original speaking voice.
To measure performance of the new system, the team compared the time it took the system to generate speech to the first indications of speech intent in Ann’s brain signals. “We can see relative to that intent signal, within one second, we are getting the first sound out,” said Gopala Anumanchipalli, one of the researchers involved in the study. “And the device can continuously decode speech, so Ann can keep speaking without interruption.” Crucially, too, this speedier method didn’t compromise accuracy—in this regard, it decoded just as well as previous slower systems. Pictured is Ann using the system to speak in near-real-time. The system also features a video avatar. Credit: UC Berkeley The decoding system works in a continuous fashion—rather than waiting for a whole sentence, it processes in small 80-millisecond chunks and synthesizes on the fly. The algorithms used to decode the signals were not dissimilar from those used by smart assistants like Siri and Alexa, Anumanchipalli explains. “Using a similar type of algorithm, we found that we could decode neural data and, for the first time, enable near-synchronous voice streaming,” he says. “The result is more naturalistic, fluent speech synthesis.”
It was also key to determine whether the AI model
was genuinely communicating what Ann was trying to say. To investigate this, Ann was qsked to try and vocalize words outside the original training data set—things like the NATO phonetic alphabet, for example. “We wanted to see if we could generalize to the unseen words and really decode Ann’s patterns of speaking,” said Anumanchipalli. “We found that our model does this well, which shows that it is indeed learning the building blocks of sound or voice.”
For now, this is still groundbreaking research—it’s at the cutting edge of machine learning and brain-computer interfaces. Indeed, it’s the former that seems to be making a huge difference to the latter, with neural networks seemingly the perfect solution for decoding the minute details of what’s happening with our brainwaves. Still, it shows us just what could be possible down the line as the distance between us and our computers continues to get ever smaller.

The image features a cartoon character standing on a sidewalk in front of a red brick wall. The character has a bald head with a few strands of brown hair on the sides, wears black-rimmed glasses, and a blue and black striped shirt. He is holding a microphone in his right hand and giving a thumbs-up with his left hand. His facial expression is cheerful, with a wide smile showing his teeth. To the right of the character, there is a black spider hanging from a web. The background includes green grass on either side of the sidewalk. The overall style of the image is simple and cartoonish, with bold outlines and flat colors.

Rear-view mirrors are important safety tools, but [Mike Kelly] observed that cyclists (himself included) faced hurdles to using them effectively. His solution? A helmet-mounted dual-mirror system he’s calling the Mantis Mirror that looks eminently DIY-able to any motivated hacker who enjoys cycling. One mirror for upright body positions, the other for lower positions. Carefully placed mirrors eliminate blind spots, but a cyclist’s position changes depending on how they are riding and this means mirrors aren’t a simple solution. Mirrors that are aligned just right when one is upright become useless once a cyclist bends down. On top of that, road vibrations have a habit of knocking even the most tightly-cinched mirror out of alignment.
[Mike]’s solution was to attach two small mirrors on a short extension, anchored to a cyclist’s helmet. The bottom mirror provides a solid rear view from an upright position, and the top mirror lets one see backward when in low positions.
[Mike] was delighted with his results, and got enough interest from others that he’s considering a crowdfunding campaign to turn it into a product. In the meantime, we’d love to hear about it if you decide to tinker up your own version.
You can learn all about the Mantis Mirror in the video below, and if you want to see the device itself a bit clearer, you can see that in some local news coverage.

One might be tempted to think that re-creating a film robot from the 1950s would be easy given all the tools and technology available to the modern hobbyist, but as [Mike Ogrinz]’s quest to re-create Robby the Robot shows us, there is a lot moving around inside that domed head, and requires careful and clever work. The “dome gyros” are just one of the complex assemblies, improved over the original design with the addition of things like bearings. Just as one example, topping Robby’s head is a mechanical assembly known as the dome gyros. It looks simple, but as the video (embedded below) shows, re-creating it involves a load of moving parts and looks like a fantastic amount of work has gone into it. At least bearings are inexpensive and common nowadays, and not having to meet film deadlines also means one can afford to design things in a way that allows for easier disassembly and maintenance.
Robby the Robot first appeared in the 1956 film Forbidden Planet and went on to appear in other movies and television programs. Robby went up for auction in 2017 and luckily [Mike] was able to take tons of reference photos. Combined with other enthusiasts’ efforts, his replica is shaping up nicely.
We’ve seen [Mike]’s work before when he shared his radioactive Night Blossoms which will glow for decades to come. His work on Robby looks amazing, and we can’t wait to see how it progresses.
