Normalise RDL as a main movement. The Romanian Deadlift (RDL) or Heavy Barbell Hip Hinge is a powerhouse exercise that has gained a lot of popularity among strength and conditioning coaches, powerlifters, and bodybuilders alike. This movement is often called an “athlete maker" in my mind due to its ability to build strength, muscle mass, and athleticism in both men and women. One of the primary reasons why the RDL is so effective for athletes is because it is triphasic, for the uninitiated meaning it involves three distinct phases of muscle action: eccentric, isometric, and concentric. During the eccentric phase, the lifter is lowering the weight, which creates tension and stress on the muscles, leading to greater muscle damage and adaptation. The isometric phase occurs when the lifter pauses at the bottom of the lift, holding the weight in a static position, which increases the time under tension and helps to build strength and stability. Finally, during the concentric phase, the lifter raises the weight, activating the muscles in a way that promotes greater hypertrophy. Compared to a traditional deadlift off the floor, the RDL places a greater emphasis on the posterior chain, specifically the proximal hamstring, glutes, and erector spinae muscles. The lift also engages the distal hamstring muscles in a nearly fully extended position, promoting greater muscle activation and strengthening. The RDL is an excellent way to develop strength and hypertrophy in these muscle groups, leading to improved overall athletic performance, including greater power, speed, and explosiveness. Given the numerous benefits of the RDL, it should be a main movement in any training program that aims to improve strength, muscle mass, and overall athletic performance. Incorporating heavy barbell hip hinge movements, such as the RDL, into your training regimen can help to promote better posture, improved mobility, and greater overall strength and athleticism. So, whether you are a powerlifter, bodybuilder, or athlete, consider adding the RDL to your training program to take your strength and athleticism to the next level.

Say hello to Boojum 👋: zkSync Era’s new high-performance proof system for radical decentralization. Boojum is an upgrade that will transition zkSync Era to a STARK-powered proof system, providing world-class performance on consumer-grade hardware. 💡 Learn more: TL;DR 👇 Boojum is the name of our Rust-based cryptographic library, which we use to implement the upgraded version of the ZK circuits for zkSync Era and the ZK Stack. The name Boojum was inspired by Lewis Carroll's poem "The Hunting of the Snark," where the Boojum represents the most fearsome kind of Snark. We intentionally designed zkSync Era in a way that cryptographic upgrades can be made without a regenesis, meaning that the Boojum upgrade won’t cause any user disruptions. Why Boojum❓ From day one, zkSync’s mission is to advance personal freedom for all — making digital self-ownership universally accessible by building a blockchain network that is trustless, secure, permissionless, affordable, easy to use, resilient and limitlessly scalable. Boojum plays an important role in advancing this mission by delivering: 1. World-class performance zkSync Era’s current SNARK-based proof system is effective today, but it won’t scale to the volume that we envision for hyperchains. zkSync Era’s sequencer can already process over 100 TPS; Boojum orders of magnitude improvements to performance complements this well. 2. Reduced hardware requirements for decentralization Our long-term goal is to enable user-powered, decentralized proof generation. Boojum represents a breakthrough in this direction — with the prover running on consumer-grade GPUs requiring only 16 GB GPU RAM. Boojum’s Journey to Mainnet 🚴🏽‍♀️ Boojum is now live on Mainnet, generating and verifying ‘shadow proofs’ today with real production data so that we can carefully test the system ahead of fully migrating. Today, we’re also open-sourcing the repo; if you’d like to take a look, you can find it here 👇 This is the first of a series of posts on Boojum. We will provide updates on our progress, including more details on implementation, security, and performance. Watch here for more, anon ∎

Wanted to chime in on this video and shed some light on what High Performance looks like in game ----- FNS calls Zellsis the most overrated player in Americas. Now to be clear I'm not coming at this butthurt as a friend of Jordan, but rather I don't think people appreciate the magnitude of impact he has on a team and on a series Whether you play ranked or compete at the highest level of this game, your team dynamic is one of the most important aspects of success. You may win without it, and let skill and strategy shine, but it won't be sustainable The things that Jordan does extremely well that need to be highlighted are: - energy - communication - mid-rounding voice - emotional awareness - effort - mental resilience - ability to stay focused when the match matters High Performance is a combination of talent and skills for sure, but more importantly it's: - attitude - behaviours - consistency - mindset - focused attention - awareness of mental intensity - intention to improve - intention to execute As you continue to build your skills in game, be sure to elevate your High Performance skills overall. It starts with awareness, then influence, then consistency! Heck you may even win more and be called overrated, but those you play with will feel your impact! ----- Again, this clip could very well just be bait to stir the pot for hype and content purposes. Respectable, if so! We need more storylines 😈😂 I'd also like to disclose that I have coached Zellsis before and I obviously have bias. I haven't worked with FNS, however I think he's funny, brilliant and would love to connect with him

So, my opinion on what the Antarctic (Antarctica) Anomaly is that it's a type of frequency technology. It must be way more powerful than HAARP, as many have claimed it to be, because we would see these anomalies at other HAARP sites, and we don't, not like this. With that said, and I'm very much trying to avoid letting what I want it to be not play a part here, I think it is a technology that is being used either off the coast of Antarctica itself or Bouvet Island. A third possibility is an area just to the northwest of the island that looks odd. It's possible it is a sonar scan from a ship, but why in that remote location? It looks like an antenna set up or rows of something that is out of place. I also believe that the weather events and fires that have taken place in Africa could possibly have been because of this. Each time we saw the anomaly, it was followed by a destructive weather event in Africa. A weird connection to that is we have been told and warned of a very busy 2024 Atlantic hurricane season. This is in part because of the above-average Atlantic ocean temperatures, which is the fuel to Hurricanes. With all this info, it's possible to see how the Anomaly could be a frequency tech that can manipulate or create weather, And or WARM up the Ocean temps to purposely enhance the Hurricane season and Storm growth. Keep in mind that many of our hurricanes and many of the biggest hurricanes have come from the west coast of Africa and form over the Cape Verde islands before heading towards the Caribbean and the United States. This is all of course speculation, and I'm learning many new things every day, so this idea may morph over time as we learn more. In the end, it is very hard to ignore all these findings. #antarctica #anonaly #AntarcticaAnomaly #BouvetIsland

HTML Artifacts are a big part of how I work with agents now. Artifacts can be more than just static files. When combined with agents, they can take action or help you take action. This unlocks all kinds of interesting ways to work with agents. This is clearly the future. Check out this writing and scheduler artifact I built in a few minutes. It uses a bit of HTML and JS. All the data is in markdown (Obsidian vaults), so the agent can access and modify it at any time. No DB needed. No sophisticated functionalities. The agent decides all that for me based on the skills, context, and memory it has access to. The best part about this simple stack is that all the important information stays with me. This has allowed me to build a recursive self-improving system and automations that can better tap into coding agents like Codex or Claude Code. I could have paid or built an entire app for scheduling posts, and there are so many of them out there. But I don't need to. I've realized a simple artifact does the job. And the simplicity of it is actually an advantage. Very little maintenance for very high returns on personalization, time, and efficiency. The other benefit of this is that I can add features as I please. That level of personalization feels magical, and we should all be pursuing more of it. All of this just keeps compounding. Of course, this example is just about writing. But I have similar artifacts for research, design, experimentation, evaluation, and so much more. And no, I didn't actually publish the post example I shared in the clip. It was just for demonstration purposes. I actually spend more time than this when writing together with agents. Lastly, having built my own agent orchestrator tool has made me realize that simplifying the tool stack is a superpower. If you are curious about how all this works, I will do a live session next week:

$QUBIC The 3 Performance Scenarios (2026 Projections) Currently, Qubic is floating with a market cap around $100M to $150M. Compared to AI giants like Bittensor ($TAO) which have already hit multi-billion dollar valuations, the upside potential is mathematically massive. 1. The "Fundamental Catch-up" Scenario (Probability: High) • Target: Reaching mid-cap AI status. • Performance: 10x to 15x • Price Target: ~$0.000010 - $0.000012 • Catalyst: The massive adoption of Oracle Machines (launched this Jan 21st) and real-world network usage for training lightweight AI models. At this stage, Qubic enters the Global Top 100. 2. The "Euphoria / Tier-1 Listing" Scenario (Probability: Moderate) • Target: Listing on major exchanges (Binance/Coinbase) and the explosion of the DePIN/AI narrative. • Performance: 40x to 60x • Price Target: ~$0.000040 - $0.000050 • Catalyst: This is where the 55% burn rate leverage hits hard. If demand surges while supply is aggressively burned by smart contract fees and Doge/XMR mining buybacks, we witness a "supply squeeze." Qubic begins to rival the peak valuations of previous cycle leaders. 3. The "AI Sovereignty" Scenario (Probability: Speculative) • Target: Aigarth becomes a credible, decentralized alternative to closed-source "Big Tech" models. • Performance: 100x and beyond • Price Target: ~$0.000080+ (deleting two zeros) • Catalyst: Qubic becomes the base layer for the "Internet of Machines." The token is no longer just a currency; it becomes "digital oil" required to power global decentralized intelligence. Why This Performance is Possible (The Analyst's Alpha) What sets Qubic apart from other "AI coins" is its internal economic engine: 1. Forced Deflation: With the activation of execution fees on January 14, 2026, every on-chain DeFi interaction destroys tokens. In a bull run, on-chain activity spikes by 1000%, mechanically accelerating scarcity. 2. Real Yield (uPoW): In 2026, investors are fleeing "vaporware." Qubic generates value through "Useful Proof-of-Work." The imminent shift to Doge mining (alongside AI) creates a unique liquidity bridge with one of the largest retail ecosystems. 3. Accessibility: The "MetaMask Snap" and Solana/L2 bridges have finally solved Qubic’s technical isolation. Liquidity can now enter with a single click. Analyst's Verdict Qubic is the ultimate "High-Risk, High-Reward" play of 2026. It’s not a coin for a 24-hour flip; it’s a bet on the decentralized AI infrastructure of the future. Expert Tip: In this 2026 bull run, don’t just watch the price. Watch the weekly burn rate. If the burn rate exceeds emissions (which is mathematically possible by Q2), we won't just be in a bull run we'll be in a parabolic "hyper-deflationary" event. And you? What is your prediction?

There’s been two papers released in the past couple months, one by Google and one by NVIDIA, that argue that ordering the documents retrieved by RAG systems can enhance performance. However, they both give two different strategies on HOW these documents should be ordered 🤔 Both papers agree on two main points: 1️⃣ There’s a fundamental issue in RAG - as more documents are retrieved, more irrelevant context (e.g., hard negatives) are introduced, which leads to confusion for the LLM and eventually degrades the quality of the generated output. This is called an inverted-U performance curve. 2️⃣ Ordering the retrieved documents is a key lever for optimizing RAG performance. Google Cloud researchers proposed ordering results based on relevance scores: The authors in this paper argue for relevance-based reordering, or ordering the retrieved chunks based on their similarity scores, so the most relevant documents are at the beginning and the end of the inputs to counter the “lost in the middle” effect. NVIDIA researchers proposed ordering results based on the original sequence of document chunks: The authors of this paper argue for Order-Preserving Reordering, or Order-Preserve RAG (OP-RAG), to maintain the logically coherent content flow of the document. So they preserved the original order of retrieved document chunks in the source text, instead of ranking them by relevance scores. So which one is right? It probably depends on the specific use case and dataset - relevance-based reordering could perform better in tasks where you need fast access to the most critical information (e.g., fact retrieval, QA systems), while order-preserving RAG might be better where you need to understand the sequential structure of information (e.g., narrative or legal documents). There are still so many uncertainties in AI - we don’t actually know what we’re doing, and it takes awhile to figure out the best strategies for most things! Excited to see more research about this.

First video of LK-99 Full Levitation, aka flux-pinning This video was just posted to the Chinese video-sharing site BiliBili and claims to be a highly pure synthesized sample of LK-99. What is the physical phenomenon behind this and what does it mean? Levitation of superconducting materials is a phenomenon unique to what is called Type-II superconductors, and is an effect whereby magnetic field lines becomes 'trapped' as it passes through the material, providing the force needed to levitate. These are the popular images and videos of cryogenically-cooled discs floating above a magnet frequently seen online and in the pinned post on my profile. You can think of this like strands of hair being caught in gum - the gum is suspended in mid-air by adhering strongly to the hair as the hair passes through it. The hair in this case is magnetic field lines and the gum is the Type-II superconductor. Just like hair comes in individual strands, or in other words hair is 'quantized' or 'discrete', so is the flux trapped at the 'pinning centers' quantized in what are called 'magnetic vortices' - the quantization of pinned flux lines is a key property and distinguishing characteristic of Type-II superconductors (although technically can occur in Type-I superconductors if the material thickness is smaller than the London penetration depth, which is indeed very small - specifics for the physics nerds out there). Flux-pinning is entirely unique to superconductors and is also wholly distinct from the Meissner effect. It is not a property of diamagnets or diamagnetism. At TRIUMF I contributed to flux-pinning studies in Niobium crystal superconducting radio-frequency cavities used for particle acceleration. In that application, trapped flux poses an issue by increasing the remnant surface resistivity of the cavity, which has the effect of decreasing its effective quality factor or Q-factor, which is a measurement of a resonators efficiency. SRF cavities typically have Q-factors of 10E10 and trapped flux at pinning centers reduces the maximum effective accelerating electric field used to drive charged particle bunches close to the speed of light. Flux pinning is thought to arise in some Type-II superconductors by small imperfections in the crystal, also called volume defects, that enable flux to penetrate the material. In SRF cavities an issue that arises is any magnetic field that is passing through the material, e.g. by the Earth's background field, can become pinned or trapped inside the cavity as it transitions into a superconducting state. See some attached plots in the comments from a study showing how the surface resistivity of SRF cavities increases the more there is a background field as the cavity transitions into superconducting state. This is the first video I am aware of that claims to show the flux-pinned levitation of a LK-99 sample. If this is in fact what is happening, then it is a very unique and promising finding of this new materials properties and potential for future study. If this is real then it is truly ground-breaking

OK, I have a definitive word on the CJ Abrams play from today's Pittsburgh Pirates at Washington Nationals game after talking with Elias Sports Bureau on this. This play will stay as a sacrifice fly. The originial ruling of NOT a sacrifice fly was for the exact same reason that I thought, which is that the infielder is not running into the outfield, which is year's past would have been correct As it was explained to me, in past years, an infielder had to be running almost in a straight line towards the outfield wall to be considered "running in the outfield". Here, since he is running, and he ends up further away from home (157 feet) than when he started (145 feet), this is going to count as a sacrifice fly. That definition is changing, in part from this play to help bring greater consistency, and to take some of the guesswork out of it (the argument that he is running into the outfield as opposed to more parallel). Now, folks all the time ask "why doesn't MLB publish the OS Manual" and I always say because it is a living document that can have the wording change, and the wording for this play will be modified to something like "more towards the outfield wall than towards home plate" to eliminate any confusion. The big key to this play is that he was running on a full sprint. Also, and this is helpful for me, but for all fly ball outs that score a run, Elias Saba reviews to ensure consistency. So, yes, it's a sacrifice fly, and now that I have that info from Elias themselves, that sort of settles this one. Sounds like the guidelines for this definition will be changing, either this season, or certainly for next season.
