text (2130): Martti Malmi, one of Bitcoin's earliest developers, just released a new version of Nostr VPN, an open-source mesh VPN that replaces the entire trust model of traditional VPN services. Traditional VPNs route all your traffic through a central server operated by a company you have to trust. They see your data. They require your email. They can log your activity. They can be subpoenaed, hacked, or shut down. Even modern mesh VPNs like Tailscale, which improved on this by sending data peer-to-peer, still require you to authenticate through a centralized coordination server using third-party accounts like Google or Microsoft. Nostr VPN eliminates the central server entirely. Your identity is a Nostr keypair, a self-generated cryptographic key pair with no registration, no email, no third-party account. The underlying transport layer is FIPS (Free Internetworking Peering System), a self-organizing encrypted mesh network where nodes authenticate each other, route traffic for each other, and establish connections without any central authority or global topology knowledge. Each node's Nostr public key (npub) serves as its network address. The architecture uses two layers of encryption: hop-by-hop encryption between peers and independent end-to-end encryption between mesh endpoints with periodic rekeying for forward secrecy. When direct connections fail due to NAT issues, the system falls back to Nostr-based multihop routing through other FIPS nodes rather than relying on company-operated relay servers. Peer discovery and NAT traversal happen through public Nostr relays using encrypted gift-wrapped messages. The new release adds native desktop apps for macOS, Linux, and Windows, an Android app, Nostr-based multihop routing for when NAT holepunching fails, and improved network management. It supports UDP, TCP, Ethernet, Tor, and Bluetooth transports simultaneously on a single mesh. This is what happens when you apply Bitcoin's design philosophy, permissionless, self-sovereign, no trusted third parties, to networking infrastructure. Built by one of the people who helped Satoshi build Bitcoin in 2009. media (48): time (10): 1779221110 time orig (10): 1779208169 id (19): 2056828532399956290 id orig (19): 2056774252490317976 uid (27): 1464280101638799360 akrmn21 uid orig (25): 915954364774326273 TFTC21

text (824): One theorem every ML engineer should know: The JohnsonLindenstrauss Lemma. It states that high-dimensional data can be projected into a much lower-dimensional space while approximately preserving pairwise distances. Why it matters: Explains why random projections work Enables scalable learning in high dimensions Used in embeddings, compressed learning, and ANN search Helps fight the curse of dimensionality The surprising part: You can reduce dimensions dramatically without destroying the geometry of the data. Thats why many ML systems can operate efficiently even with massive feature spaces. Modern representation learning is deeply connected to this idea: Good embeddings preserve structure while compressing information. In ML, compression is often not loss of intelligence its removal of redundancy. media (48): time (10): 1778440606 time orig (10): 1778338100 id (19): 2053554859081666664 id orig (19): 2053124917122433097 uid (27): 1464280101638799360 akrmn21 uid orig (29): 1569037991372521472 probnstat

text (1854): THE ENTIRE AI INDUSTRY JUST GOT HUMILIATED a tiny model trained in just a few hours on a single graphics card is planning 48x faster than billion-dollar supercomputers. It actually understands physics instead of just memorizing patterns. yann lecun was right the whole time for three years every major lab told you the same story. scale is all you need. just throw more GPUs at it. just train on more tokens. eventually the model will "wake up" and understand the world. it was a lie. or at minimum, a very expensive bet that just lost. LeCun kept saying generative AI is a dead end. predicting the next pixel or the next token is fundamentally wasteful, the model burns trillions of parameters memorizing surface details instead of learning how reality actually works. he proposed JEPA instead. predict abstract concepts in a compressed thought space. don't paint the world pixel by pixel, understand it. the problem was JEPA kept collapsing. left to its own devices the model would cheat, mapping a dog, a car, and a human to the same point in latent space. technically minimizes the loss. learns absolutely nothing. every fix was ugly. seven loss terms. frozen encoders. EMA tricks. stop-gradients. the kind of duct-tape engineering that should have been a red flag. then LeCun's team dropped LeWorldModel. they replaced all the hacks with one regularizer that forces the latent space into a gaussian distribution. the model can no longer cheat. to make accurate predictions it has to actually encode physics. 15 million parameters. single GPU. trains in hours. plans 48x faster than foundation world models. detects physically impossible events on its own. meanwhile OpenAI is raising another $40B to train GPT-6 on a data center the size of manhattan. the entire scaling thesis just got embarrassed by a model that fits on a gaming PC. media (112): 91ff4c64d595495e217fe194dae09297c6c2125088d5283235afb9a32c0ccfa7 time (10): 1778316063 time orig (10): 1778245594 id (19): 2053032487446618279 id orig (19): 2052736920351068411 uid (27): 1464280101638799360 akrmn21 uid orig (30): 1628683814993027072 heyrobinai

text (1089): Bitcoin just made a meaningful step toward future quantum resistance An updated version of BIP 360 has just been merged into the official Bitcoin BIP GitHub repository. The update introduces Pay-to-Merkle-Root (P2MR), a proposed new output type that omits Taproots quantum-vulnerable key-path spend while preserving compatibility with Tapscript and script trees. It also includes: - Removal of Taproots quantum-vulnerable key-path spend in a separate opt-in new output type. - A foundation for introducing post-quantum signatures while using Tapscript/script tree for spend time optionality. - The change is a soft fork that does not affect existing Taproot outputs. - Addition of Isabel Foxen Duke as co-author, to ensure the BIP was clear and understandable to the general public, not just the Bitcoin developer community. The BIP also addresses criticism about Bitcoin devs not taking the quantum threat seriously. We are grateful to every Bitcoin contributor who took the time to review and provide feedback.

text (845): Anthropic had 16 AI agents build a C compiler from scratch. 100k lines, compiles the Linux kernel, $20k, 2 weeks. To put that in perspective GCC took thousands of engineers over 37 years to build. (Granted from 1987 - however) One researcher and 16 AI agents just built a compiler that passes 99% of GCC's own torture test suite, compiles FFmpeg, Redis, PostgreSQL, QEMU and runs Doom. They say they "(mostly) walked away." But that "mostly" is doing heavy lifting. No human wrote code but the researcher constantly redesigned tests, built CI pipelines when agents broke each other's work, and created workarounds when all 16 agents got stuck on the same bug. The human role didn't disappear. It shifted from writing code to engineering the environment that lets AI write code.

text (1709): Xorg is proposing a new main branch of their X11 server which: - Would go back in time, and re-base itself on code from February of 2024 (almost 2 years ago) and - Rename their branch from master to main. Putting aside the obviously woke main branch name change The goal here appears to be to make new releases of Xorg which have as little influence as possible from past contributions by the main developer of @XLibreDev. While the motivation of Xorg seems obvious Xorg has personal animosity towards the lead developer of XLibre, stemming from a combination of him forking Xorg as well as him having non-Leftist political views (which is not allowed) the fact that Xorg is looking to make an effort at new releases *at all* is more than a little peculiar. Over the last few years, key developers of Xorg (and Wayland) have made it clear that a primary goal of the Xorg Foundation is to, ultimately, kill off Xorg entirely (in order to drive adoption of Wayland, by force). And, to that end, they have been working quite hard, refusing (literally) thousands of code submissions over many years and dragging their feet on significant features and fixes (many of which are already incorporated into the XLibre fork). Is this a reaction to the widespread adoption of XLibre, which appears to be gaining momentum? Or, perhaps, is this bizarre strategy prompted by the fact that Wayland adoption has stagnated (sharing roughly equal market share as Xorg/XLibre), despite forcing Wayland on users for several years? Will this approach be formally adopted? It appears likely, as this is a proposal from Alan Coopersmith, an Xorg Foundation Board member and Xorg release manager.
