BJJ jargons, the language of pajama-wrestling. Brazilian Jiu-Jitsu has more jargon than a startup pitch deck. Here’s the greatest hits: General Terms Gi – the kimono/judo-like uniform you sweat into. No-Gi – training without the gi, in rashguards and shorts. Basically “slippery mode.” Roll – sparring. No, not sushi. Tap / Tap Out – surrendering before your joints snap. Usually involves frantic slapping. OSS – the universal grunt of respect, agreement, greeting, or just filler noise. Nobody agrees on its origin. Positions Guard – you on your back with legs wrapped around the opponent, pretending it’s intentional. Closed Guard – legs locked around your opponent’s waist like a desperate koala. Open Guard – same thing, but legs free and flailing. Half Guard – you trap one of their legs, basically halfway between dead and alive. Mount – sitting on someone’s chest like a smug gargoyle. Side Control – pinning them sideways, crushing hopes and ...

The Art of the Meal: Trump’s TACO Diplomacy

Image
In May 2025, a new nickname for President Donald Trump— "TACO," short for "Trump Always Chickens Out" —emerged and quickly gained traction across financial circles and social media platforms. Coined by Financial Times columnist Robert Armstrong, the term critiques Trump's pattern of announcing aggressive tariffs that unsettle markets, only to later retract or soften these measures in response to negative economic reactions.   This pattern has led to the so-called "TACO trade" strategy among investors: buying stocks during market dips caused by Trump's tariff threats, anticipating a rebound when he retreats from these positions.  The nickname has also become a viral meme, with images depicting Trump adorned with tacos and chickens circulating widely. Comedian Jimmy Kimmel highlighted the trend on his show, further amplifying its reach.  President Trump has publicly expressed his displeasure with the moniker, labeling questions about it as "nast...

Trump's Immigration Wins and Legal Speed Bumps

Image
 The U.S. Supreme Court has recently delivered significant rulings that bolster President Donald Trump's immigration policies, while also delineating constitutional boundaries. Key Victories for the Trump Administration Termination of Humanitarian Parole Programs : The Court permitted the administration to end temporary humanitarian parole for approximately 532,000 migrants from Venezuela, Cuba, Haiti, and Nicaragua. This decision reverses a prior injunction and subjects many to expedited removal, aligning with Trump's stricter immigration enforcement stance.  Revocation of Temporary Protected Status (TPS) : An emergency Supreme Court order allowed the administration to revoke TPS for about 350,000 Venezuelans, marking one of the largest removals of legal protections in U.S. history.  Judicial Checks and Due Process Concerns Despite these victories, the Court has imposed limitations to safeguard constitutional rights: Alien Enemies Act Limitations : The Cour...

Major Factors Behind Rising Long-Term U.S. Treasury Yields

Image
 When the  yields    (interest rates)  of l ong-term U.S. treasury bonds such as the  10-Year Treasury  go up, it means the U.S. government must pay more to borrow money for these bonds. This change reflects investor behavior and broader economic conditions. Here’s a comprehensive list of all major causes of rising 10-year Treasury yields: 📈 1. Inflation Expectations Increase If investors think future inflation will rise, they demand higher yields to compensate for the reduced purchasing power of their returns. This is one of the most common reasons yields rise. 🏦 2. Federal Reserve Policy (Tightening) When the Fed raises short-term interest rates , long-term yields often rise too — especially if the Fed signals inflation is a risk. The Fed also affects long-term rates by: Ending bond purchases (quantitative easing) Selling bonds (quantitative tightening) 📊 3. Strong Economic Growth A growing economy increases dem...

特朗普的美国制造业伟大复兴梦

Image
特朗普政府政策的核心目标只有一个。正如万斯（JD Vance）本周在演讲中所说，其目标是推动美国制造业的伟大复兴。 特朗普认为，要按照他设想的经济、社会和政治方向改造美国的关键，在于恢复全国各地的工厂和铸造厂。 不幸的是，这种情况不仅极不可能发生，而且推动这一目标的努力将付出高昂代价，并对美国人民造成伤害。 美国应该制造更多产品”这个想法很有吸引力。我们都认为，一个富裕而强大的国家应该拥有巨大的工厂，冒着浓烟，源源不断地生产商品并销往全球。这种印象深深刻在我们的脑海里。然而，这实际上是 过去的景象，而非未来的发展方向 。 当今世界上最发达的经济体几乎都由服务业主导。在全球最富裕的工业化国家中，服务业占据了绝大多数的就业岗位。在美国，非农就业岗位中，服务业占比超过80%，而制造业仅占不到10%。 美国向世界出口的主要产品并不是实体商品，而是软件及软件服务、娱乐、金融服务等无形产品。而且，在这些领域，美国对全球并不是贸易逆差，而是贸易顺差。 为什么会出现这种转变？ 因为当人们变得更富裕、受教育程度更高时，他们会 花更多钱在服务上，而不是商品上 。在1960年，美国消费者在商品上的消费支出占比超过50%。而到了2010年，这一比例下降到了 33% ，企业真正赚钱的地方已经从商品转向了服务。 举个例子，一双运动鞋的制造成本可能只有25到30美元，但它的真正价值体现在设计、市场营销和销售，这些环节决定了最终能够卖到100美元。那么，你更希望你的工人从事制造业，还是参与高价值环节？ 在过去40至50年间，制造业在各国经济中的占比，以及制造业就业在总就业中的占比，都在稳步下降。 1973年，美国制造业就业占比约为25%，如今已降至约8%。 英国、加拿大 的情况类似，即使是传统的制造业强国，如 德国、法国、日本 ，制造业就业比例也大幅下降。 日本的案例：特朗普想要效仿的国家 日本是一个重要的研究案例，因为它基本上做了特朗普希望美国做的所有事情。 日本通过高关税和贸易壁垒保护国内市场免受外国商品竞争。 政府大力推进产业政策，扶持制造业发展。 社会崇尚制造业，教育系统强调技术技能和工匠精神。 然而，日本的制造业仍然在稳步衰退。事实上，我们甚至可以说，正是这些政策导致了日本产业的衰落。 政府支持的行业（如VHS录像机、随身听等）最终错过了技术...

Predictive Processing -- Mind and Reality

Image
Me: Predictive processing, a theory suggesting that our perception of reality is a controlled hallucination. The brain generates predictions and sends them to our sensory systems, meaning what we see, feel, or hear isn’t direct reality but a reflection of these predictions. How do you explain this? Plato: The idea you're referring to comes from the predictive processing theory, which is a cutting-edge perspective on how the brain interprets the world. According to this theory, perception isn't just a passive reception of sensory information; instead, the brain constantly generates predictions about what it expects to happen based on past experiences. These predictions are then compared to incoming sensory signals, and the brain updates its understanding of the world accordingly. In simpler terms, your brain creates a model of the world and uses that model to predict what's going to happen next. When you see something, for example, your brain doesn’t just wait for the imag...

美国对加拿大征25%关税, 加国雷霆反击

 突发新闻。加拿大总理特鲁多正在发表讲话。 特鲁多:  今天，美国对加拿大，他们最亲密的伙伴和盟友，他们最亲密的朋友， 发动了一场贸易战。同时，美国却在谈论与俄罗斯积极合作，安抚普京——一个撒谎成性、双手沾满鲜血的独裁者。这合理吗？ 加拿大人是理性且有礼貌的。但当我们的国家和所有公民的福祉受到威胁时，我们绝不会退缩。 目前，美国的关税已于今天凌晨生效，加拿大的回应也随之启动。加拿大将对价值1550亿美元的美国商品征收25%的关税，其中对300亿美元的商品立即生效，而剩下的1250亿美元商品将在21天后生效，除非这些关税被取消。我们正在与各省和地区进行积极而持续的磋商，探讨多项非关税措施，以明确传达一个信息——在贸易战中没有赢家。 就像一个月前一样，我首先想直接对美国人民讲话。我们不想要这一切。我们希望作为朋友和盟友与你们合作，我们也不想看到你们受到伤害。但你们的政府选择了这样做。 截至今天早上，市场下跌，通胀预计将急剧上升。你们的政府选择让美国数千家依赖加拿大材料或加拿大消费者的企业面临风险。它们选择了提高美国消费者的生活成本——从日常必需品如食品和汽油，到汽车和住房等大额消费品，无一例外。它们选择损害美国的国家安全，阻碍美国获取丰富的关键矿产、能源、建筑材料和化肥，而这些资源对美国的繁荣至关重要。 它们选择发动一场贸易战，而这首先会伤害的就是美国的家庭。它们选择破坏自己的议程——那个本应带领美国迈入黄金时代的议程。它们选择破坏我们共同努力解决芬太尼问题的成果，而芬太尼是一种必须被彻底消灭的毒品。 因此，我要明确表示，今天的这些关税完全没有正当理由，也毫无必要。美国政府为这些关税寻找的法律借口是，加拿大不愿意帮助打击非法芬太尼。但这完全是错误的。 让我们看看事实。我们的边境已经是安全且受控的。流入美国的芬太尼中，来自加拿大的不到1%。非法入境美国的人口中，来自加拿大的也不到1%。但我们仍然采取了行动，因为我们知道，我们总是可以做得更好。我们回应了包括总统在内的各种关切，实施了一项雄心勃勃的13亿美元边境计划。该计划包括对新型人工智能和成像技术的重大投资，以阻止芬太尼的流动。我们加强了与美国执法机构的协调和信息共享，同时部署了无人机、直升机和额外的人员，以确保我们的边境安全。 一个月前，作为与美国达成的暂停关税协议的一部分，我们作出了...
