The article expresses concern about service providers being punished for the actions of their users, similar to the situation with Kim Dotcom. It questions why certain service providers like Google, Discord, and Reddit, which contain illegal content, do not face legal consequences. The article also mentions the issue with infrastructure providers and how this situation could potentially be a slippery slope with unclear boundaries, allowing the government to arbitrarily blame certain individuals or companies. The author wonders if they are being naive in their thinking.
Top 2 Comment Summary
The comment section of this article contains many unfavorable opinions. The main point being made is that Telegram did not have encrypted groups as a default feature, and they had illegal content on their servers that they were aware of but did not cooperate in addressing. Comparisons to other providers are considered irrelevant because they either cooperate more in handling unencrypted information or, like Signal, do not have access to such material or store it for long. The article emphasizes that it is not legally possible to operate an unmoderated content platform and one must always remove illegal content and cooperate with law enforcement.
2. Defenders think in lists, attackers think in graphs (2015)
Total comment counts : 26
Summary
The article discusses how network defense often fails because defenders don’t have a clear understanding of the network’s assets. Instead of focusing on protecting individual assets, defenders should view the network as a graph, where assets are interconnected through security relationships. Attackers exploit these relationships to breach a network. The article explains that defenders should visualize their network as a graph and implement controls to protect all interconnected assets. Defenders have an advantage over attackers because they have full information about their network, while attackers have to study it piece by piece. The article emphasizes the importance of managing the network based on reality rather than relying on outdated asset inventory systems or incomplete network diagrams.

The article discusses the difference between attackers and defenders in the context of cybersecurity. Attackers have a specific mission, such as stealing data or causing disruption, and are able to explore deeply until they accomplish their goals. Defenders, on the other hand, such as the SOC (Security Operations Center), have to manage multiple signals and threat vectors simultaneously and need to prioritize which ones require their attention. The article suggests that defenders should be able to “think in graphs” by analyzing patterns and connections in the data, but without defenders actively monitoring the data, this may not be possible. The author’s suggestions to improve defense would essentially be additional signals for defenders to check against.
Top 2 Comment Summary
The article suggests that defenders use lists and checklists to manage their assets, as they often have to handle a large number of them. It also recommends that defenders create dependency graphs after making lists, ensuring that items on the lists are up to date, assuming limited trust and isolating resources. In contrast, attackers only need to focus on a few things.

AMD’s latest mobile chip, Strix Point, offers a larger GPU and slight architecture upgrade compared to its previous generation. The iGPU is built from Workgroup Processors (WGPs), which are similar to cores in the CPU world. Strix Point has eight WGPs, which is a significant increase compared to the previous generation. The memory subsystem remains similar to the previous generation, with two shader arrays and a shared cache. The iGPU connects to the rest of the chip via four Infinity Fabric ports, which run at a lower frequency to save power during graphics workloads. The memory controller supports up to LPDDR5-7500, providing high bandwidth. Cache latency and DRAM latency have improved compared to the previous generation, and RDNA 3.5 has a scalar memory access path. Strix Point provides more bandwidth for its extra compute, and its memory subsystem offers impressive performance. In comparison, Intel’s Meteor Lake has less cache bandwidth but a larger L2 cache. The article also mentions the outdated APU in Valve’s Steam Deck, which has lower cache bandwidth compared to modern contenders. Overall, modern iGPUs have comparable bandwidth to low-end GDDR5-equipped GPUs of the past, thanks to LPDDR memory technology.

Total comment counts : 11
Summary
The article discusses the use of Language Model-based Machine Learning (LLMs) for automatic root cause analysis (RCA) for cloud incidents. The proposed system matches incidents to incident handlers, predicts the root cause category, and provides an explanatory narrative. The author expresses concern about using LLMs for RCA, suggesting that a more principled and custom-designed machine learning system would be more appropriate. They emphasize the importance of holistic RCA that explores causes in different dimensions and considers relationships between potential causes. The author references safety engineering expert Nancy Leveson’s approach to accident analysis in complex systems. They argue that relying solely on LLMs for RCA could lead to a decline in developing new experts and may result in superficial analyses. The article also mentions the potential problem of automation surprise and highlights the importance of designing predictable automated systems and providing adequate training. Overall, the author is worried that using LLMs for RCA could lead to cost cutting and systemic failures in the long term.
Top 1 Comment Summary
The article questions the suitability of Language Models (LLMs) for analyzing cloud incidents and determining the root cause. LLMs are good at predicting written language but lack knowledge about how complex systems work. While they can generate interesting stories and even accidentally provide the correct diagnosis, it is coincidental and not based on reasoning over evidence. LLMs excel at summarizing detailed postmortem documents but are not appropriate for analyzing failures in complex systems. The ease of using LLM technology has led to its optimistic but potentially misguided inclusion in problem-solving attempts.

The article discusses the cost of housing mice in a cage. The author mentions that the upfront cost for a cage of 5 mice is around $1,000, with a recurring cost of about $5,000 per year. However, they suggest that mice can be obtained at a cheaper price depending on the vendor and mouse type. In their workplace, it costs approximately $2 per day to house a cage of 5 mice, and if you get C57BL/6NJ mice from Jackson, it costs about $30 per mouse. Therefore, the cost for 5 mice would be around $150, and the yearly housing cost would be about $800. The article also briefly mentions the size of antibodies, which is around 10-12 nm.
6. Generating Mazes
Total comment counts : 17
Summary
The article discusses different algorithms for generating 2D grid mazes. The author explains the concept of perfect mazes, where there is only one unique path between any two cells. They describe the process of connecting cells with edges, creating walls between cells without edges, and rendering unreachable cells as dark.
The article introduces three maze generation algorithms: Aldous Broder, Random Depth-First Search (DFS), and Wilson’s Algorithm. Aldous Broder uses a random walk-based method to visit every cell, creating an unbiased maze but with inefficiencies. Random DFS visits each cell once by stepping to a random unvisited neighbor, but tends to create long corridors. Wilson’s Algorithm performs a loop erased random walk, starting at a random unvisited cell and erasing any created loops. The author mentions that Wilson’s Algorithm is faster than Aldous Broder but hasn’t found rigorous proof.
The author also discusses finding the start and end positions in the maze. They suggest using two breadth-first searches to determine the two furthest points and then randomly selecting the start and end positions from these points.
Throughout the article, the author provides code examples and mentions resources for further exploration, such as the Wikipedia page on Maze generation algorithms.

The article emphasizes the importance of double-checking the results when using an LLM (large language model) like Claude to extract lists and data. While the accuracy of LLMs is generally high at 99.9%, there can still be errors with 1 or 2 records. These errors can be difficult to detect because the results appear plausible upon a quick glance. Specifically, long lists or tables may be prone to slight mistakes. The article suggests trusting the LLM’s output but also verifying its accuracy. One approach to ensure machine verifiability is to ask the LLM to write a Python validator that can be executed internally.
