someone built a tool that puts ANY FACE on your webcam in REAL TIME called DOT - deepfake offensive toolkit, open source, works right now dot injects a real-time deepfake into your virtual camera zoom, google meet, teams, any video call app sees the fake face as your real webcam it ships with multiple deepfake engines (FOMM, SimSwap, SimSwapHQ), you pick the model based on your GPU and how real you need it to look built by sensity ai for red teams to test if your identity verification actually holds up against deepfakes

#Deepfakes are videos, images, even sounds artificially generated by #machinelearning For the first time, a virtually aged deepfake of a 9-year-old child has been created so that she can act and argue like an adult woman. Ella is representative of an entire generation of children. Experts predict that by 2030, two-thirds of all cases of identity theft will occur in this way. Possible consequences include profiling by data brokers, hacking, facial recognition, pedophilia and others Credits: Deutsche Telekom

Meanwhile the Ukrainians revealed that the counter-offensive is nothing more than a “psychological operation against the aggressors” and all this time they were just trolling everyone in order to buy themselves time for the real counteroffensive. Can you imagine the grief of the family of a dead soldiers near Zaporozhye or Avdeevka, who learned that not only did his command destroy him just like that, for the sake of intimidating Muscovites and for fun, but they would not receive any payments for this, since there was a counter-offensive and it wasn’t there at all?

🚨 ALERT: I've implemented a system for near-instant deepfakes (🎥 Video & 🎤 Audio) — we’re talking LIVE Webcam/Microphone to near-real-time Deepfake Video/Voice. Tomorrow, someone else will. Are we ready for a world where seeing isn’t believing? 🤔 This isn’t sci-fi anymore. The tech to manipulate audio and video in near-real-time exists now. I’ve built upon it, used it in real-time meetings, and I’m sure others have or will soon too. We need urgent action: 🧠 Teach digital skepticism 🛠️ Develop better detection tools (I’m actively working on this) This isn’t future tech—I’ve used it in actual meetings. It’s not about fear—it’s about preparedness. What is your organization doing to address this?

This is so cool. Tesla can take footage from its massive vehicle fleet and synthetically create new driving scenarios to test edge cases and improve safety for its self-driving software. Tesla can also stitch footage from all 8 cameras into a fully drivable 3D environment—letting engineers steer, brake, and navigate as if they were on real roads, all powered by neural network–generated video streams. • Can simulate 8 Tesla camera feeds simultaneously — fully synthetic. • Used for testing, training, and reinforcement learning. • Allows adversarial event injection (e.g., adding a pedestrian or vehicle cutting in). • Enables replaying past failures to verify new model improvements. • Can run in near real-time, letting testers “drive” inside a simulated world.

The "three fingers in front of your face" test (also called the 3-Finger Test) is a simple, viral trick popularized in early 2026 for spotting deepfakes or AI-generated video during live calls, especially with scammers. How It Works On a video call (Zoom, FaceTime, etc.), you ask the other person: "Can you hold up three fingers in front of your face?" A real human does this easily — their hand overlaps their face naturally. Many (especially older) deepfake or real-time face-swap systems struggle with this because: - They have trouble rendering occlusion (when the hand blocks part of the face) accurately in real time. - This often causes visible glitches: blurring, warping, distortion, unnatural blending, or the AI refusing / hesitating because it can't process the complex interaction properly. In the original viral clip (from cybersecurity researchers like Jim Browning and Huntress Labs), a suspected scammer hesitates, deflects ("That's too much..."), partially complies poorly, or the video glitches — exposing the fake. Why It Fits the Cognitive Wild West This test is a practical example of the "Cognitive Wild West" idea: in an era of synthetic media, people are developing quick hacks and personal "defenses" because there's no widespread, reliable system for verifying reality. It's low-tech cognitive security against high-tech deception — part of the arms race between AI creators and everyday users trying not to get scammed or manipulated. Limitations (It's Not Foolproof) Already becoming obsolete — Newer, more advanced deepfake models (as of mid-2026) handle hand-face interactions much better. Scammers now know the trick and can train around it or use better tech. It works best on real-time generated deepfakes, not pre-recorded or highly polished ones. False confidence is a risk: relying on one trick can make you less safe if you ignore other red flags (odd lighting, unnatural eye movement, audio mismatches, etc.). Better Practices in the Wild West Security experts recommend combining it with: - Asking for unpredictable actions (e.g., specific movements or objects). - Verifying identity through other channels (call back on a known number, check details independently). - Using emerging detection tools or just defaulting to higher scepticism on unsolicited video calls. It's a fun, memorable meme in the broader discussion of living with AI-generated content, but like everything in this space, it's temporary — the frontier keeps moving.

Trevor Wittman Says Justin Gaethje Will Be More Offensive With His Grappling Against Paddy Pimblett 🥊👀 "We're ready for everything. We did not go into this fight thinking it's going to be just a striking fight at all. The proudest thing with Justin is the amount of time he's put into his grappling because his wrestling is so high level. When we had the Oliveira fight, we were defensive, and you can't win fights like that. You have to win offensively, and Justin is one of those guys, when you grapple with him, his ground and pound is so unique." (Via ESPN MMA )

XBOW raised $117M to build AI hacking agents. Now someone just open-sourced it for FREE. Strix deploys autonomous AI agents that act like real hackers - they run your code dynamically, find vulnerabilities, and validate them through actual proof-of-concepts. Why it matters: The biggest problem with traditional security testing is that it doesn't keep up with development speed. Strix solves this by integrating directly into your workflow: ↳ Run it in CI/CD to catch vulnerabilities before production ↳ Get real proof-of-concepts, not false positives from static analysis ↳ Test everything: injection attacks, access control, business logic flaws The best part? You don't need to be a security expert. Strix includes a complete hacker toolkit - HTTP proxy, browser automation, and Python runtime for exploit development. It's like having a security team that works at the speed of your CI/CD pipeline. The best part is that the tool runs locally in Docker containers, so your code never leaves your environment. Getting started is simple: - pipx install strix-agent - Point it at your codebase (app, repo, or directory) Everything is 100% open-source! I've shared link to the GitHub repo in the replies!

To everyone wondering if Tesla's FSD moat has eroded thanks to Nvidia's keynote - here's the answer: Think of Nvidia as a seller of a toolkit. You can buy pieces built specifically for a job but once you have the tools you still have to build the entire project. In this case...a model Many seem to be in awe over Nvidia's Cosmos which is a platform that includes World Foundation Models that can generate synthetic data for training AI systems like autonomous vehicles I'll go into much more depth in today's episode but here's a clip of Ashok Elluswamy at CVPR '23 explaining how Tesla is already using a similar approach to augment its real world data set This also doesn't even consider the fact that much of the auto industry using Nvidia "tools" will be forced to pay 50%+ margins just to buy the toolkit and will be locked in to Nvidia's system Nor does this touch on legacy auto needing to hire top ML engineering talent to actually put these tools to work The path to autonomy will be real world data as the foundation and simulations/synthetic data as a supplement. There is no path to autonomy with synthetic data alone. More to come later $TSLA As Elon said earlier this year, "it's remarkable how quickly we run out of human-created data. Reality itself and synthetic data ftw" "What you are seeing here is purely generated video sequences - given the past videos the network predicts some sample from the future, hopefully the most likely sample. It is being predicted not just for one camera, but it predicts for all 8 cameras around the car jointly" - Ashok

🚨 $TSLA AI VP ASHOK ELLUSWAMY SAYS CURSE OF DIMENSIONALITY MAKES SELF-DRIVING AN EXTREME COMPRESSION CHALLENGE • Tesla cars stream ~2 billion tokens from 8 high-res cameras + history buffer every few seconds, but must compress it all down to just 2 actions (steering + accel/brake) • The real difficulty is learning the correct causal reasons without spurious correlations (e.g., brake because of turn signal, not a moving tree branch) • Tesla fleet generates ~500 years of driving data daily, but most is boring → they proactively identify and collect only rare/interesting events (school buses, skids, hazards) • Large fleet allows fast capture of extremely rare scenarios that are hard or unsafe to stage • With enough rare data, the system achieves proactive safety and early prediction (e.g., braking seconds before a potential crash by reading abnormal vehicle behavior) • Bottom line: self-driving needs massive high-quality edge-case data for real predictive intelligence in real time

Vector Database by hand ✍️ ~ 10 steps walkthrough below Vector databases are the backbone of Retrieval Augmented Generation (RAG). How do they actually work? Goal: index three sentences, then answer a query by finding the nearest one, filling in every cell yourself. = 1. Given = A dataset of three sentences, three words each. In practice it is millions of them. = 2. Word embeddings = Let us look up each word in an embedding table. Here the vocabulary is 22 words; in practice it is tens of thousands, and the vectors have thousands of dimensions rather than four. = 3. Encoding = We feed the sequence to an encoder, one linear layer and a ReLU, and get one feature vector per word. In practice the encoder is a transformer. = 4. Mean pooling = Let us average across the columns. Three word vectors collapse into one, which is what people mean by a text embedding or a sentence embedding. = 5. Indexing = We multiply by a projection matrix and the four dimensions become two. It is doing the job of a hash: a short representation that is faster to compare, and it is what gets saved in the vector storage. = 6. Process "who are you" = Let us repeat steps 2 to 5 on the second sentence. = 7. Process "who am I" = We do it a third time. The database is now indexed. = 8. Query "am I you" = Let us push the query through the very same pipeline: lookup, encoder, mean pooling, projection, and it lands as a 2D vector in the same space. = 9. Dot products = We transpose the query and multiply, which takes the dot product against every stored vector at once. The dot product is the estimate of similarity. = 10. Nearest neighbour = Let us scan for the largest: 60/9 beats 44/9 and 40/9, so the answer is "who am I". Scanning billions of vectors one at a time is what makes this the slow step in practice, which is why real databases use an approximate nearest neighbour index like HNSW. The outputs: Stored index vectors = [5/3, 2/3], [5/3, 0], [7/3, 2/3] Query vector = [8/3, 2/3] Dot products = 44/9, 40/9, 60/9 Nearest neighbour = "who am I" The takeaway: a vector database is an embedding pipeline, a projection, and a dot product. Every step here is arithmetic you can do in pen, which is worth remembering when the word "database" makes it sound like something else. 💾 Save this post!

Encoding = We feed the sequence to an encoder, one linear layer and a ReLU, and get one feature vector per word. In practice the encoder is a transformer. = 4. Mean pooling = Let us average across the columns. Three word vectors collapse into one, which is what people mean by a text embedding or a sentence embedding. = 5. Indexing = We multiply by a projection matrix and the four dimensions become two. It is doing the job of a hash: a short representation that is faster to compare, and it is what gets saved in the vector storage. = 6. Process "who are you" = Let us repeat steps 2 to 5 on the second sentence. = 7. Process "who am I" = We do it a third time. The database is now indexed. = 8. Query "am I you" = Let us push the query through the very same pipeline: lookup, encoder, mean pooling, projection, and it lands as a 2D vector in the same space. = 9. Dot products = We transpose the query and multiply, which takes the dot product against every stored vector at once. The dot product is the estimate of similarity. = 10. Nearest neighbour = Let us scan for the largest: 60/9 beats 44/9 and 40/9, so the answer is "who am I". Scanning billions of vectors one at a time is what makes this the slow step in practice, which is why real databases use an approximate nearest neighbour index like HNSW. The outputs: Stored index vectors = [5/3, 2/3], [5/3, 0], [7/3, 2/3] Query vector = [8/3, 2/3] Dot products = 44/9, 40/9, 60/9 Nearest neighbour = "who am I" The takeaway: a vector database is an embedding pipeline, a projection, and a dot product. Every step here is arithmetic you can do in pen, which is worth remembering when the word "database" makes it sound like something else. 💾 Save this post!

Been optimizing my ASS OFF now that jnmartin has pushed all of his progress on his Star Fox 64 Sega Dreamcast port to a private GitHub repo to collaborate with a bunch of us DC devs before release. MAN this thing is HIGHLY optimized already... We're essentially running a high-level emulator for the N64's RSP coprocessor, doing graphics transforms, matrix math, and display list conversions not only on the main SH4 CPU, but also sitting atop a high-level OpenGL driver, in real-time. Not only that, but once again, we're doing all audio synthesis and mixing also on the main SH4 CPU, so this thing is doing a literal asston on the main CPU with what might seem like a relatively straightforward port. 99% of the time, everything runs flawlessly, but when you drop a bomb on a shitfest of enemies in a densely populated area, as with the N64 original, the FPS can dip momentarily. Here's a direct hardware capture of me testing a new SH4 optimized routine out for gainz on my Sega Dreamcast... this mofo is meant be used for one-off 3D vector transforms by a single matrix which has not been preloaded into the XMTRX FP register matrix back-bank. Rather than doing a full 4x4 load on the matrix just to do a single 4D transform via the FTRV instruction, we're simply peforming 3 3D dot products against a single 3D vector, allowing us to pipeline the loads, dot products, and store operations better than doing a load all at once followed by a transform, and we aren't wasting a lane on the FPU for a 0.0f W component!
