The article discusses the theme of Markov chains being funnier than large language models, and the author asks for 10 jokes on this theme. Claude responds with the following jokes:
- Why did the Markov chain cross the road? To get to the other side of unpredictability.
- An LLM and a Markov chain walk into a bar. The LLM orders a statistically probable drink. The Markov chain orders a lampshade made of cheese.
- What do you call a Markov chain that tells dad jokes? A Mark-ov Twain.
- How many LLMs does it take to screw in a lightbulb? One - but it’ll spend 20 minutes explaining the optimal lightbulb-screwing process first.
- Knock knock. Who’s there? Markov. Markov who? Markov chain reaction of nonsensical hilarity.
- An LLM, a Markov chain, and GPT-4 walk into a bar. The bartender says “We don’t serve your kind here.” GPT-4 leaves. The LLM stays to debate ethics. The Markov chain orders a bicycle made of spaghetti.
- What’s an LLM’s favorite movie? Predictable and Furious 17: The Safest Driving Yet.

Roblox, although not profitable, has strong operating cash flow, which is a more important measure than accounting-defined profits. In the past twelve months, the company’s operating cash flow was $650 million, accounting for about 20% of its revenue. Roblox has remained cash-positive for at least twenty-four quarters. This highlights the phenomenon where companies like Roblox prioritize increasing cash flow over immediate profitability. If the cash flow ever stops increasing, they can adjust by reducing reinvestment spending to maintain sustainability.

The article proposes a concept that could potentially be used to bypass the stalking features implemented by Apple and other companies. The concept involves using multiple donor tags that cycle through different tags every 24/N hours. This would make it difficult for Apple or any device tracking system to follow a person continuously using a single tag.
6. The Quantum Butterfly Effect
Total comment counts : 11
Summary
Scientists at Los Alamos have discovered that quantum-level disruptions can be controlled and do not spiral out of control over time. They found that it is possible to take a particle in a specific quantum state back in time and modify its state in the past without significantly changing it in the present. This contradicts the butterfly effect, which suggests that small changes can lead to large effects. The butterfly effect can be understood in two ways: chaotic behavior in complex systems and amplification of small changes over time. The scientists have worked out the quantum analogues of both versions and found that quantum chaos is not immediately apparent in the equations of quantum physics. Classical physics allows for chaotic behavior, but quantum physics describes particles as diffuse entities with wave properties. However, studying chaotic behavior in the quantum realm often involves accounting for non-pristine systems, such as considering the influence of stray radio waves or magnetic fields on quantum objects.

7. Parsing protobuf at 2+GB/s: how I learned to love tail calls in C (2021)
Total comment counts : 19
Summary
The Clang compiler has added a new feature that allows guaranteed tail calls in C, C++, and Objective-C using the [[clang::musttail]] or __attribute__((musttail)) attributes. Tail calls are often associated with functional programming, but they can also improve performance. The article mentions that using tail calls in protobuf parsing has resulted in significant speed improvements. The author believes that major language interpreters written in C could also benefit from this technique. However, there is a downside in terms of portability as musttail is currently a nonstandard compiler extension. The article explains what tail calls are, their benefits, and how they optimize stack memory and reduce the performance overhead of function calls. The author also mentions that tail call optimization is not new to Clang, but the new feature guarantees the optimization in all build modes. The article concludes by referencing Mike Pall, the author of LuaJIT, who wrote LuaJIT’s interpreter in assembly instead of C to achieve better performance, highlighting the challenges that C compilers face with interpreter main loops.
Top 1 Comment Summary
The article describes a proposal for a C standard for tail call optimization. The proposal suggests using “return goto (expression);” instead of standardizing the “musttail” feature. This method guarantees that the lifetimes of local objects will end, making it easier to implement without extensive escape analysis. A link to the proposal is provided for more information.
Top 2 Comment Summary
The article mentions an old RFC (Request for Comments) in the Rust programming language community that proposed adding a “become” keyword to guarantee Tail Call Optimization (TCO). This proposal was originally postponed to focus on other goals, but it has recently been revisited. The article shares links to the original RFC and the recent revisiting of the initiative.
8. Seven basic rules for causal inference
Total comment counts : 13
Summary
The article discusses seven basic rules that govern the relationship between causal mechanisms and the associations or correlations observed in data. These rules serve as building blocks for causal inference. The rules are explained using causal graphs and logic terms, and simple simulation R code is provided to demonstrate their practical application. The four elemental building blocks of causal graphs are described, including chain paths, fork paths, collider paths, and causally independent variables. The article also discusses the correlation between variables, the role of common ancestors and descendants, and the importance of randomization in experimental control. Adjustment, or controlling for variables, is also explained as a means of analyzing relationships in data.
Top 1 Comment Summary
The article discusses the issue of collider bias in research studies and emphasizes the importance of controlling for a collider variable in order to obtain accurate results. Collider bias occurs when an independent variable has a common effect on both the dependent variable and another independent variable, leading to a spurious correlation. The article suggests that researchers should consult subject matter experts and develop a directed acyclic graph (DAG) to explicitly outline the causal assumptions. By doing so, it becomes easier for other researchers to propose alternative causal structures and test the robustness of the results. The article also mentions the DAGitty tool as a helpful resource for creating DAGs.
Top 2 Comment Summary
The article discusses the concept of correlation between independent and dependent variables. It states that while independent variables can be not correlated, it is important to note that dependent variables can also be not correlated. The example given is of a dependent variable, Y, which is determined by the value of an independent variable, X. Despite this relationship, the correlation between X and Y is zero.

10. NASA acknowledges it cannot quantify risk of Starliner propulsion issues
Total comment counts : 24
Summary
NASA is still unsure whether to bring two astronauts back to Earth on Boeing’s Starliner spacecraft or extend their stay on the International Space Station due to safety concerns. The Starliner has experienced issues such as suspect thrusters and helium leaks, and it needs to depart the space station before SpaceX’s next Dragon crew mission. NASA officials had expected to make a decision this week, but it is now likely to be made at the end of next week or the beginning of the week of August 26. The thruster issue is being investigated by propulsion experts, as five of Starliner’s thrusters failed during approach to the space station. While most of the thrusters have recovered, engineers are uncertain whether they will work normally on the journey back to Earth.
