Automattic: "Earlier today, CEO Matt Mullenweg shared the following note with Automattic employees. We are deeply grateful to all departing Automatticians. automattic.com/2025/04/02/res..." Link
JJ: "Another day, another @OSSCapital portco on page across all of @GitHub ... big congrats to @StevenTey and @DubDotCo: Short links with superpowers = link mgmt platform for modern marketing teams (attribution, analytics, and a ton more)." Link
JJ: "Starting our launch day strong @TryCompAI --- very excited about the first open source disruptor to Vanta / Drata. Get your SOC, ISO and more compliance checks done in weeks not months!" Link
JJ: "I'm so proud of @LatentHoldings for representing the vast majority of Bittensor code contributors and (very) active maintenance ... with nearly 200% more code commits (1,521) than our beloved founders Ala and Jake. Congrats to @basfroman (Roman Chkhaidze) on top place." Link
JJ: "Digging into the @Gaia_AI_ Bittensor subnet (57) ... no GPUs required to mine this one! Super cool reward mechanism for accurate prediction of DST (disturbance storm time) indices. This subnet can massively improve space weather forecasts, protecting satellites and power grids, and unlock commercial opportunities in defense / military contexts. github.com/Nickel5-Inc/Ga..." Link
Steven Tey: "Excited to launch our new @dubdotco Creators page. With Dub, creators can share real-time analytics with the brands they work with -- which builds trust + increases revenue. Featuring world-class creators like @hubermanlab, @efficientapp, @craylormade, and @blackevilgoblin." Link
Laτenτ Holdings: "We are now 10 team members full time strong. Launched in December last year, < 4 months old, relentlessly shipping TAO.app, maintaining Bittensor CLI, SDK, lots of substrate, official developer docs, @learnbittensor, and much more cooking on the subnet front." Link
Documenso: "We moved off Next.js documen.so/leaving-nextjs Let us know what you think" Link
JJ: "Hard Facts: 90%+ of the largest and most profitable technology companies in human history raised ZERO venture capital (if they did it was not needed, ala Google). VC has grown into a bloated and contrived "asset class" that should have stayed a cottage, highly specialized service industry with very potent but small funds only investing at the absolute earliest stages (0-10~ people)." Link
JJ: "Not April Fools. Just great shipping @rustdesk. Just realized that we are also the most adopted and active open source Rust project in the world." Link
Laτenτ Holdings: "Today we are thrilled to welcome Travis Millott to the team as our Co-Head of Education. Travis (@taotemplar) has been one of the leading contributors to Bittensor's accessibility and community learning, creating a treasure troves of explanation videos on Bittensor's design, econometrics, subnets and a lot more. Latent will continue investing heavily in dramatically reducing the complexity, friction and difficulty to understand the latest development and commodities on the network." Link
JJ: "Bittensor is categorically the most disruptive thing in crypto since Bitcoin ... Crypto VCs almost all hate it (few have been forced to accumulate, with extremely weak conviction aside from @OSSCapital). $TAO is a DEX, AI firehose, abstract incentive market, compute aggregator, inference producer, training layer, data creation engine, agent infra, and a TON more .. all in one. And the community is vastly made up of non-crypto-native builders." Link
Evan You: "'With the move to React Router, we're now leveraging Vite for bundling, and it's transformed our workflow completely. Development feels almost instant. Our dev servers refresh so fast, they're practically indistinguishable from running a production build. We've regained momentum, joy, and most importantly, productivity.'" Link
OpenBB: "We're officially SOC 2 Type II compliant. This achievement underlines our dedication to protecting customer data and aligns with our core mission: empowering enterprises to create and utilize secure and scalable data and AI solutions." Link
deniz: "Cal is just so much better in every way I don't even get why people use calendly" Link
Forward Email: "Email providers claim to be "open-source," but most only show you their frontend while keeping their backend code hidden. We're 100% open-source---both frontend AND backend. Unlike Proton and Tuta, you can verify exactly how your emails are processed. forwardemail.net/blog/docs/why-..." Link
Gumroad: "Gumroad is officially open source! After 14 years of helping creators earn over $1,000,000,000 (that's a billion), we're giving everyone direct access to our entire codebase." Link
JJ: "Big congrats to @TryCompAI on PH of the day yesterday. Now to disrupt Vanta / Data and revolutionalize the GRC category through open source." Link
PyQuant News: "In case you're unfamiliar: OpenBB is the first AI financial workspace that combines data integration with an AI agent to transform investment research. - Private (your data is not shared) - 100s of free data sources - Custom data backends - Advanced AI Copilot How it works:" Link
Forward Email: "How @Canonical powers email across @ubuntu, @kubuntu, @LubuntuOfficial, and @edubuntuproject domains with Forward Email's 100% open-source enterprise solution! SSO with @launchpad_net API Custom @UbuntuOne branding Quantum-resistant forwardemail.net/blog/docs/cano..." Link
JJ: "Awesome case study by @Canonical, one of the top Linux companies (creators of @ubuntu) on their use of @fwdemail to power email infra!" Link
JJ: "Wow. I just realized TAO.app is just over a month old from the public beta. We are so excited to the roadmap here ... trading, fundamentals data, alerts, forensic chain analysis (mining, staking, validating, root, alpha deep dives) ... so much more coming." Link
Deryck: "WordPress isn't just "for blogs." It's the backbone of ecommerce stores (Woo), membership platforms, enterprise sites, and more. If you're still underestimating it, you're missing out on one of the most flexible tools on the web." Link
Cal.com: "Are you trying to build a calendar scheduling system from scratch? The cost is usually the first headache people face. And we're not just talking dollars here. The TIME cost is equally brutal, you hire someone to build it, but there's no guarantee it'll work exactly as intended." Link
JJ: "VCs chasing GH stars is old news.. Bittensor subnets are open source projects w/ Bitcoin-like currencies bolted on top. ~50 days in, < 100 subnets are worth $6B+ with billions in emission pouring in over coming months. The bar is LOW. There should be thousands of subnets today!" Link
JJ: "Another gem subnet... Storage is a critical commodity for AI. Storb (Bittensor Subnet 26) is making great progress. Miners are rewarded for low latency, high storage / retrieve success rates + PDP (proof of data possession). github.com/storb-tech/sto... @storbdevs @shr1ftyy" Link
