Babel was being constructed before our eyes and there was some mechanism for separating the masterpieces from the random strings of text, and all the masterpieces were dropping as fast as publishers could scoop them up? Would authors stop writing then
The Dark Night of Mathematics - by Kirwin Hampshirehe creation (or even the pursuit) of novel mathematics is one way that humans have historically accessed the ineffable and encountered the divine and mystical
The Dark Night of Mathematics - by Kirwin HampshireIn contrast, we’ve shown that high-quality proprietary datasets labeled by expert investors and used for fine-tuning produce custom models that exceed frontier performance on our tasks
Learning to Replicate Expert Judgment in Financial Tasks - Thinking Machines Labif a model couldn’t match an example from its own training set then either the example is genuinely difficult, or the original label was wrong.
Learning to Replicate Expert Judgment in Financial Tasks - Thinking Machines LabAfter examining the reasoning traces of the model we realized that the labels in the dataset were often wrong. Since expert labelers are costly, we devised a verification scheme that routes only the contested examples to experts
Learning to Replicate Expert Judgment in Financial Tasks - Thinking Machines LabFine-tuning sidesteps this: rather than contorting the expert’s intuition into a static prompt, the training process lets the model develop its own judgment
Learning to Replicate Expert Judgment in Financial Tasks - Thinking Machines LabGPT 5.4 costs 43% more than 5.2 but is only marginally more accurate.
Learning to Replicate Expert Judgment in Financial Tasks - Thinking Machines LabOur proprietary model outperforms all frontier models we tested on information accuracy and recall, at a fraction of their cost.
Learning to Replicate Expert Judgment in Financial Tasks - Thinking Machines LabThis metadata is stored in the router, and tells it that the user table is sharded on its id column using the user_hash shard index. This user_hash shard index uses the router's built-in value hashing. For each incoming row, it hashed the ID, and uses this to send it to the correct shard to be stored.
Making 768 servers look like 1 — PlanetScaleThe router must understand the data topology, create a plan for distributing the query to all shards that may contain matching results, aggregate the results back at the router, and send the full result set to the client.
Making 768 servers look like 1 — PlanetScaleIn the kernel community we do open source because it results in better technology, not because of religious reasons. And so we make decisions primarily based on technical merit. Not fear of new tools.
Re: Linking Patchwork with Sashiko? - Linus TorvaldsReal container support was added to the Linux kernel only in 2013, however. This is what made namespaces really useful and brought them to the masses
What Are Namespaces and cgroups, and How Do They Work? – NGINX Community BlogPre-merge, this took 5.9 billion uncached input tokens, 690 million output tokens, and 72 billion cached input token reads — around $165,000 at API pricing. By hand, I think this would've taken 3 engineers with full context on the codebase about a year, during which time we wouldn't be able to improve Node.js compatibility, fix bugs, fix security issues or implement new features.
Rewriting Bun in Rust | Bun BlogIf you need a paragraph-long comment to justify why the workaround is OK, the code is wrong — fix the code.
Rewriting Bun in Rust | Bun BlogUsually with humans, the person reviewing the code is not the person who authored the code. The person writing the code wants to merge the code, which can bias their actions to ship before it's ready.
Rewriting Bun in Rust | Bun BlogThe main problem with DP is that coming up with DP exercises is not free — someone has to spend time developing effective DP exercises for your skill domain.
Expertise Acceleration - CommoncogIdeas without the right maturation of capabilities won't find product-market fit. The key is recognizing which applications are on the cusp of viability at a given moment based on the evolution of the technology
Where Are the Good AI Products? - by Varun ShenoyThe Chinese interpretation of 4 as unlucky is a more recent development, considering there are many examples, sayings and elements of the number 4 considered as auspicious instead in Chinese history.[2]
Chinese_numerologyInterning works by ensuring that there’s only one canonical copy of each distinct string in memory. It can give the following benefits:
Fast and Simple Rust Internerany counterparty who predictably trades in the direction of future price moves is informationally advantaged. The markout measures this regardless of why.
Markouts: Measuring Adverse Selection | Udit SamaniBackground volatility 𝜎 σ, by contrast, does not shift the expected markout curve at all. Larger 𝜎 σ just makes the distribution wider, requiring more trades to reliably estimate the mean.
Markouts: Measuring Adverse Selection | Udit SamaniThe crossover time 𝜏 ∗ = − 1 𝜆 ln ( 1 − 𝑠 / ( 2 𝛼 𝜇 ) ) τ ∗ =− λ 1 ln(1−s/(2αμ)) is the window you have to hedge before a toxic fill turns into a loss
Markouts: Measuring Adverse Selection | Udit SamaniConcentrated toxicity suggests a specific adversarial counterparty; diffuse toxicity suggests the market structure itself has changed
Markouts: Measuring Adverse Selection | Udit Samaninet edge (gross minus adverse selection). The markout at long horizon is the net edge
Markouts: Measuring Adverse Selection | Udit SamaniIn practice, you fit 𝛼 𝜇 αμ and 𝜆 λ from the empirical curve, then directly use 𝛼 𝜇 αμ to set your minimum spread:
Markouts: Measuring Adverse Selection | Udit SamaniThis crossover time defines your safe holding horizon: if you can fully hedge your inventory before 𝜏 ∗ τ ∗ , you escape the adverse selection
Markouts: Measuring Adverse Selection | Udit SamaniThe spread exceeds the long-run adverse selection cost. You earn positive expected PnL on every trade
Markouts: Measuring Adverse Selection | Udit SamaniPnL starts at 𝑠 / 2 s/2 and decays to a positive but smaller long-run value. You still make money, but less than the gross spread suggests
Markouts: Measuring Adverse Selection | Udit Samanithe same spread is worth less when informed traders move prices more.
Markouts: Measuring Adverse Selection | Udit Samaniquickly the informed signal appears in the mid price. Large 𝜆 λ: information is revealed quickly, the adverse selection hits you fast
Markouts: Measuring Adverse Selection | Udit Samaniinformation cost: the fraction of trades that are informed, multiplied by how much each informed trade ultimately moves the price
Markouts: Measuring Adverse Selection | Udit SamaniThe mid price will drift upward as their information is incorporated into the market
Markouts: Measuring Adverse Selection | Udit Samanihey trade for idiosyncratic reasons — portfolio rebalancing, hedging, liquidity needs. Their trades carry no information about future price direction. After an uninformed buy, the mid price is equally likely to go up or down
Markouts: Measuring Adverse Selection | Udit Samanimarkouts are often reported from the taker’s perspective
Markouts: Measuring Adverse Selection | Udit Samaniif the price rose after you sold, you lost money on the short position you’re now holding. That price rise is adverse selection — the buyer knew more than you
Markouts: Measuring Adverse Selection | Udit SamaniIt is the simplest diagnostic in market making: does the price move toward you after a fill (good) or against you (toxic)?
Markouts: Measuring Adverse Selection | Udit Samanithe virtuous entrepreneur, recognizing that her rewards are disproportional to her merit, and that the farmers’ compensation is not proportional to the value they create (and to the risks and efforts they undertake) would seek a fairer distribution of the overall value created (for instance, by paying farmers more for their product
Profit-Seeking, Self-Interest, And Virtue | Finance and PhilosophyOf course, these profit-seekers should get moral credit by profiting only from entrepreneurial profits; it takes moral fortitude to forgo the opportunity to profit through rent seeking (
Profit-Seeking, Self-Interest, And Virtue | Finance and PhilosophyA value-creating padre, recognizing that resources in the POW camp would be much better allocated if prisoners used a bulletin board to exchange their goods, would promote the use of such board even though this would put a stop to his trading bonanza
Profit-Seeking, Self-Interest, And Virtue | Finance and PhilosophyThe opinion towards the padre in the camp was not positive. It was said that he did not improve the traded products but merely “resold’’ them at a higher price, profiting at the expense of others. Munger and Russell argue that this assessment is mistaken. The padre corrects a mistaken allocation of resources, helping those who don’t smoke get cheese in exchange for their cigarettes. Thus, he did not profit at the expense of others, but earned his profits by finding opportunities that created value for others and reducing transaction costs (
Profit-Seeking, Self-Interest, And Virtue | Finance and Philosophypolicy can influence the allocation of entrepreneurship more effectively than it can influence its supply
Entrepreneurship: Productive, unproductive, and destructive - ScienceDirectsociety's entrepreneurial activities varies much more because of their allocation between productive activities such as innovation and largely unproductive activities such as rent seeking or organized crime
Entrepreneurship: Productive, unproductive, and destructive - ScienceDirectThe paradox is you need both. Explore the noise until you have signal. Then exploit that.
The Mathematical Reason Most People Never "Make It"Patterns are emerging. “Oh, this is what works. Huh.” That’s your √n. The late game is exploitation. You double down on the winners. You cut out the losers. You focus your energy towards the best bet
The Mathematical Reason Most People Never "Make It"You can’t know which 10 posts out of 100 will blow up without posting all 100. You can’t know which skills are your multipliers without trying a bunch of skills. You can’t know which relationships matter without meeting a lot of people.
The Mathematical Reason Most People Never "Make It"Some people will compound their advantages. Most won’t. Mathematics doesn’t give a fuck about fairness or ethics. Compounding systems create exponential distributions, that’s it.
The Mathematical Reason Most People Never "Make It"Price’s Law suggests that if you’re consistently in that square root across multiple domains, luck isn’t the full story. You might actually be cooking at a different level, and the isolation you feel—the sense that few people “get it”—is mathematically predictable
The Mathematical Reason Most People Never "Make It"surprise is a pretty visceral emotion, and is good at hacking into my motivation system
