I'm Done with Social Media
(I'm Done with Social Media)

In her blog post, Caroline Crampton discusses her journey with social media, ultimately deciding to step away from it. At the beginning of 2024, she aimed to promote her upcoming book, "A Body Made of Glass," by actively using social media. Despite her efforts, including training sessions and regular posts, she found herself uncomfortable and overwhelmed. She felt that social media distorted her perception of life, making her see everything through the lens of potential content for sharing.

As she continued to engage with platforms like Instagram and TikTok, she realized that her posts were not effectively reaching new readers and were consuming a significant amount of her time and energy. She felt that the pressure to be active on social media was misplaced, especially for non-celebrity authors. After some reflection, she concluded that social media was not the right tool for her, and she began to feel liberated after stepping back.

Crampton decided to focus on creating a blog instead, where she could share her thoughts and work without the pressures of social media algorithms. She aims to communicate with her audience through her blog and newsletters, valuing quality interactions over quantity. In summary, she emphasizes the importance of finding a personal and fulfilling way to connect with her readers rather than relying on social media, which she sees as a burden rather than a benefit.

Upgrading an M4 Pro Mac mini's storage for half the price
(Upgrading an M4 Pro Mac mini's storage for half the price)

In July 2025, the author upgraded their M4 Mac mini from 1 TB to 2 TB using a DIY kit. They were then approached by M4-SSD to test a new upgrade for the M4 Pro Mac mini, increasing its storage from 512 GB to 4 TB.

The upgrade process involved removing the rear cover of the Mac mini, which can be tricky due to a delicate power button connector. The M4 Pro uses a unique storage slot that requires a Device Firmware Update (DFU) restore, which can be done using certain Intel Macs or Apple Silicon Macs.

After completing three upgrades, the author noted that performance was strong, especially in write speeds due to the additional flash chips in the new SSD. The internal storage of the Mac minis performed consistently well compared to an external Thunderbolt drive.

The 4 TB SSD upgrade is priced at $699, which is less than Apple's offering of $1,200, but still higher than typical 4 TB NVMe SSDs that cost between $200 and $400.

Conspiracy theorists unaware their beliefs are on the fringe
(Conspiracy theorists unaware their beliefs are on the fringe)

A recent study by Cornell University researchers reveals that people who believe in conspiracy theories often show high levels of overconfidence and tend to think that many others share their beliefs, even when they are actually in the minority. The research indicates that these individuals frequently overestimate their own cognitive abilities, making them less analytical in their thinking. They misjudge the popularity of their views, believing they are part of the majority about 93% of the time, despite evidence showing that very few people support their ideas.

The study involved 4,181 U.S. adults and included tests on perception and numeracy to measure overconfidence. Participants were asked about common conspiracy theories, such as the belief that the moon landings were faked. The results suggest that overconfidence plays a significant role in fostering conspiracy beliefs, as those who are less competent often fail to recognize their own shortcomings.

This tendency to think most people agree with them complicates efforts to counter misinformation, as those who need help distinguishing truth from falsehood are often unaware of it. The findings highlight the growing concern over conspiracy theories, especially with the rise of social media.

Overtourism in Japan, and how it hurts small businesses
(Overtourism in Japan, and how it hurts small businesses)

The text discusses the issue of overtourism in Japan and its negative impact on small businesses, particularly in cities like Kyoto.

Key points include:

  1. Small Businesses vs. Overtourism: Small businesses thrive on community and local connections, but overtourism leads to a focus on transient tourists rather than regular customers, harming the businesses' essence.

  2. Negative Effects of Social Media: Platforms like TikTok can catapult small shops into the spotlight, attracting crowds that disrupt local life and diminish the personal connections that owners cherish with their customers.

  3. Community Loss: As small businesses cater to tourists, the local community suffers. Business owners often feel overwhelmed and disconnected from their original purpose, which was to serve locals.

  4. Travel Trends: The rise of affordable travel and the growth of the middle class have led to an influx of tourists in Japan, many of whom prioritize social media-worthy experiences over genuine exploration.

  5. Alternative Tourism: The author advocates for exploring less tourist-heavy areas in Japan, suggesting that cities like Morioka and Yamaguchi offer rich experiences without the drawbacks of overtourism.

  6. Economic Strategies: The text suggests Japan could better manage tourism by adjusting tax policies and entrance fees to mitigate the impact of mass tourism on residents.

Overall, the author emphasizes the importance of sustainable travel that respects local communities and small businesses, while also recognizing the potential for positive tourism experiences when approached thoughtfully.

Repaste Your MacBook (But Don't)
(Repaste Your MacBook (But Don't))

The author reflects on their experience with their M1 Pro MacBook Pro, which has served them well over four years. While the laptop still performs efficiently for tasks like video editing and coding, its fans have become noticeably louder during intensive tasks. This change is attributed to the aging thermal paste, which helps transfer heat away from the CPU.

Thermal paste can dry out and become less effective over time, so the author decided to replace it. They used a high-quality thermal paste but encountered issues during the process, including damaging a fan cable and a Touch ID sensor cable, which would require costly repairs. Despite these setbacks, replacing the thermal paste and fan led to improved temperatures and quieter operation.

The author advises that unless someone is experienced with delicate electronics, they should consider professional help for such repairs. Overall, the process improved their MacBook's performance, but they miss the Touch ID feature.

Postgres LISTEN/NOTIFY does not scale
(Postgres LISTEN/NOTIFY does not scale)

Summary

Recall.ai, which records millions of meetings monthly, faced significant issues with their Postgres database due to its LISTEN/NOTIFY feature. This feature caused a global lock during transactions, leading to severe slowdowns and downtime when many simultaneous writers (meeting bots) were active.

Key Findings:

  • Problem Discovery: Between March 19-22, 2025, the database experienced downtime characterized by high load but low CPU and I/O performance, indicating locking issues.
  • Bottleneck Identification: The NOTIFY commands were found to create a global lock during transaction commits, which serialized all commits and led to major performance degradation with multiple writers.
  • Testing Results: Load tests showed that when LISTEN/NOTIFY was used, the database struggled, but removing it allowed for full CPU utilization and quicker recovery from load spikes.
  • Solution: The team decided to stop using LISTEN/NOTIFY and handled the notification logic at the application level instead. This change was implemented quickly and resolved their performance issues.

The overall conclusion is that using LISTEN/NOTIFY in a highly concurrent environment like theirs is not scalable.

Martha Wells, the author of the Murderbot Diaries, emphasizes that current artificial intelligence (AI) technologies, like large language models, are far from the sentient machines depicted in science fiction. She argues that the real concern is how tech companies may exploit robots for profit, rather than a threat from sentient AI.

In her Murderbot series, the main character is a security unit that gains free will by hacking its controlling system, highlighting themes of corporate control and the struggle for autonomy. The series critiques corporate personhood and its negative impact on society, reflecting real-world issues related to greed and exploitation.

Wells notes that while her fictional universe includes a relatively free society called Preservation, it still grapples with issues, unlike the more oppressive Corporation Rim. She believes that true machine intelligence is still years away and that current AI lacks sentience, describing it more as advanced algorithms than true intelligence.

Wells also touches on themes of neurodiversity, suggesting her writing reflects her own experiences and emotions.

Gut microbes could protect us from toxic 'forever chemicals'
(Gut microbes could protect us from toxic 'forever chemicals')

Scientists have found that certain gut microbes can absorb harmful PFAS chemicals, known as "forever chemicals," which are linked to serious health issues like cancer and fertility problems. By increasing these beneficial bacteria in our gut, we may be able to reduce the negative effects of PFAS on our health.

Research from the University of Cambridge showed that these microbes can take up PFAS from their environment and remove it from the body through waste. The bacteria were able to absorb between 25% and 74% of PFAS within minutes of exposure. While this has only been tested in mice, it suggests a promising role for gut bacteria in detoxifying PFAS.

The scientists aim to create probiotic supplements to boost these helpful bacteria in humans. There are over 4,700 PFAS chemicals in common products, and they can linger in our bodies for years. Researchers emphasize the need to mitigate the health impacts of these chemicals, as they are widespread in our environment and food.

As they work on developing new probiotics, the researchers recommend avoiding PFAS-coated cookware and using good water filters as immediate steps to protect ourselves.

AI coding tools can reduce productivity
(AI coding tools can reduce productivity)

A recent study by METR has found that AI coding tools may actually decrease productivity for experienced developers. Despite widespread claims of increased efficiency, the study showed that developers using AI tools experienced a 19% drop in productivity compared to their expectations, which they estimated would be a 20% increase.

The study involved 16 experienced developers from open-source projects, who completed 246 tasks under two conditions: with and without AI tools. The results were surprising, as developers believed they were working faster, but the data revealed they were slower when using AI.

Key reasons for this decrease in productivity include:

  1. Quality of AI Output: Developers often found the AI-generated code inadequate, leading to time spent reviewing and correcting it.
  2. Increased Idle Time: Developers spent more time waiting for AI responses, disrupting their workflow.
  3. Overuse of AI: Some participants relied too heavily on AI, which did not contribute positively to their productivity.

The study emphasizes that while AI tools can be beneficial in some contexts, they may not be effective for complex projects with high-quality standards. Developers with less experience tend to see more productivity gains from AI tools, suggesting that these tools are better suited for simpler tasks rather than mature, intricate codebases.

Overall, the findings suggest that AI coding tools have limitations that need to be addressed, and improvements in these tools may lead to better productivity outcomes in the future.

    • Ensure the host's /var or /run directory is mounted in the container.
    • Common locations for socket files include /var/run and /run. Check CR documentation for specifics.
    • Projects like Tetragon, Crictl, and Tracee have hardcoded paths for these sockets to facilitate connection.
  2. Make a gRPC Connection:

    • Use the CRI API to establish a connection.
    • Code examples show how each project handles this connection.
  3. Query Information:

    • After connecting, projects can query details about containers and pods.

Example Code:

  • Tetragon: Contains default socket paths and uses gRPC to connect and query container status.
  • Crictl: Attempts to connect using predefined socket endpoints.
  • Tracee: Uses a function to enrich container data by querying for container details, including namespaces and labels.

Key Takeaways:

  • The connection to CRs is essential for Kubernetes awareness in tools.
  • Each project has specific methods for locating sockets and querying container information, using gRPC for communication.

Is Gemini 2.5 good at bounding boxes?
(Is Gemini 2.5 good at bounding boxes?)

Summary of Gemini 2.5 Object Detection Benchmark

  • Performance Overview: Gemini 2.5 Pro is a decent object detector, comparable to Yolo V3 from 2018, achieving around 0.34 mAP on the MS-COCO dataset.

  • Dataset Details: MS-COCO is a well-known dataset in object detection with 80 classes. It contains 5000 validation images, but it's unclear if Gemini used this data during training.

  • Testing Method: The author evaluated Gemini by creating a prompt that instructs it to detect all visible objects and provide details like label, confidence, and bounding box. The model was tested with structured and unstructured outputs, and different token budgets.

  • Key Findings:

    • Gemini Pro outperformed Flash and Flash-Lite models.
    • Using a "thinking budget" negatively impacted performance.
    • Structured output was generally better for Pro, while unstructured was better for Flash models.
    • Gemini can sometimes produce better results than actual ground truth data.
  • Conclusion: While CNNs remain faster and more reliable with good training data, Gemini 2.5 Pro shows promise in versatility for open-set tasks, making it useful for future projects. The benchmark is somewhat biased as CNNs are specifically trained on the COCO classes.

The European Cloud/Computing Situation
(The European Cloud/Computing Situation)

Summary of the European Cloud/Computing Situation

The European cloud computing landscape has evolved significantly, moving from traditional software ownership to the Software as a Service (SaaS) model. Here are the key points:

  1. Traditional Software Ownership: Companies used to buy software licenses, which would run on local computers without needing regular updates. This model limited software companies' earnings, as users hesitated to buy new licenses.

  2. Shift to Software as a Service (SaaS): SaaS allows users to access software online, paying monthly or yearly subscriptions. This model reduces the need for local IT support but often leads to "shadow IT," where departments bypass IT and deal directly with SaaS providers.

  3. Dependence on US Cloud Providers: Many SaaS companies now rely on major US cloud providers (Amazon, Microsoft, Google) for their services, leading to a heavy reliance on non-European infrastructure. For instance, Dutch municipalities outsource citizen services to these US providers, raising concerns about data sovereignty.

  4. Challenges for European Providers: Although Europe has capable server and computing resources, no local providers offer the advanced services that US hyperscalers do. This has led to a situation where even non-SaaS software is often tied to US cloud infrastructure.

  5. Education and Market Norms: Educational institutions primarily teach US cloud technologies, further entrenching reliance on these platforms. This has made it difficult for organizations to consider alternatives, even when they could be cheaper.

  6. Path Forward: To change the current situation, Europe needs to develop SaaS providers that can operate on local clouds. Cooperation among European cloud providers could help create advanced services that might compete with US offerings. Encouraging governments to use these local services can promote sovereignty in digital infrastructure.

  7. Long-term Changes Needed: Transitioning away from entrenched systems, especially those integrated with Microsoft technologies, will take years and substantial effort.

In summary, Europe is currently locked into US cloud services, and the focus should be on building a robust European cloud infrastructure to promote digital sovereignty and independence.

Reverse Engineering the Firmware Loader for an X-Rite Spectrophotometer
(Reverse Engineering the Firmware Loader for an X-Rite Spectrophotometer)

The author found two X-Rite/Pantone RM200 spectrophotometers on eBay for just $20 each, despite them typically costing hundreds. A spectrophotometer measures color and helps users find precise shades, particularly useful in graphic design. Unfortunately, the devices they received were cosmetics models designed only for measuring skin tones, which weren't useful for the author.

After discovering that the hardware might be the same as the more versatile base model, the author decided to try updating the firmware to unlock its full capabilities. They used X-Rite's Capsure Sync software and found a way to intercept the software's requests to the X-Rite servers, allowing them to load the base model's firmware onto their devices.

After successfully installing the new firmware, the devices booted with the correct branding. The author calibrated the spectrophotometers and found that they provided mostly accurate color readings compared to old Pantone fan decks, although some readings were slightly off. Overall, the experiment was successful, and the author noted that the information shared is for educational purposes only and does not endorse replicating their work.

Summary of the Blog Post "Regarding Prollyferation" by Nick Tobey

In a follow-up to a previous post on Prolly Trees, Nick Tobey discusses the concept of these data structures and the idea of parallel invention, where similar innovations emerge independently. Prolly Trees are a type of Merkle Tree, created by recursively applying a content-defined chunker to files, allowing for efficient data storage and version control.

Tobey notes that after his initial post, others contributed examples of similar implementations, such as rdedup and Jumbo Store, which also utilize recursive chunking. However, he emphasizes that not all implementations meet the criteria for Prolly Trees, particularly in how they handle structured data.

Aaron Boodman, a co-creator of Noms and the person who coined the term "Prolly Tree," clarified that Prolly Trees are distinct because they manage structured key-value data, unlike other variations that focus solely on file storage. This structured approach allows for efficient querying and merging of data, which is vital for their functionality.

The post also delves into the properties that define a Prolly Tree: history independence, structural sharing, query capability, and efficient diffing/merging. While some other implementations share similar properties, they lack the semantic depth that Prolly Trees offer.

Tobey discusses other related designs, such as those from BlueSky and XetHub, which also achieve similar functionality but in different ways. He concludes by questioning whether the term "Prolly Trees" refers to the abstract data type or the specific data structure, highlighting that language and definitions in the tech world can evolve over time.

Overall, the post reflects on the importance of understanding the nuances of these data structures and encourages discussion within the tech community.

Foundations of Search: A Perspective from Computer Science (2012) [pdf]
(Foundations of Search: A Perspective from Computer Science (2012) [pdf])

The chapter by James A. R. Marshall and Frank Neumann discusses the challenges and principles of search in artificial intelligence (AI) from a computer science perspective. Here are the key points:

  1. Search in AI: Search algorithms are fundamental to AI, helping machines mimic natural intelligence. They are used in various applications, from games like chess to solving complex problems like the traveling salesman.

  2. Computational Hardness: Many search problems are computationally hard, meaning they cannot be solved efficiently. Problems are categorized by their solvability: some can be solved in polynomial time (efficient), while others require exponential time (inefficient).

  3. Examples of Hard Problems: The 3-SAT problem, a specific type of Boolean logic problem, exemplifies hard search problems. Finding solutions for 3-SAT requires exponential time, while simpler problems like 2-SAT can be solved efficiently.

  4. NP-Complete Problems: Problems like 3-SAT are representative of NP-Complete (NP-C) problems, for which no efficient algorithms are known. The consensus is that efficient solutions for these problems likely do not exist.

  5. Heuristic Approaches: Since efficient algorithms for many problems are unavailable, heuristic methods are explored. However, the "no-free-lunch" theorems suggest that no single heuristic is universally superior across all problems.

  6. Average Case vs. Worst Case: Hard problems might be easier on average than in the worst case. For instance, many instances of 3-SAT are easy to solve, suggesting that brains might rely on shortcuts based on average-case scenarios.

  7. Performance of Heuristics: Simple heuristics, such as gradient descent, can often outperform random search strategies. These heuristics can yield better-than-average solutions for certain classes of NP-C problems.

  8. Learning and Evolvability: The chapter also touches on learning as a search process. It introduces the PAC (probably approximately correct) learning model, which explores how algorithms can learn from examples and classify new instances.

  9. Genetic Programming: This is a practical application of evolutionary algorithms, where functions are evolved to solve problems. Genetic programming has been successfully applied in various fields, but its theoretical foundations are still being developed.

  10. Satisficing vs. Optimizing: The authors argue that in complex search problems, the goal should be to find "good enough" solutions rather than optimal ones, as optimal solutions may not exist.

Overall, the chapter emphasizes that while search is crucial for intelligence—both natural and artificial—most search problems are complex, and efficient solutions may not be achievable. Instead, heuristics and satisficing strategies are more practical approaches to solving these problems.

Summary:

Sipgate, a cloud telephony provider, discovered a technical issue in the MediaTek VoLTE firmware affecting certain smartphones when connecting to their network. This problem caused devices from brands like Huawei, Xiaomi, Gigaset, and Motorola to crash during call setups due to a missing "Contact" header in SIP messages.

Although these phones could connect to the internet and make calls using 2G, they failed to respond to incoming VoLTE call invitations, leading to call failures. After extensive testing and collaboration with researchers, Sipgate identified the bug and notified both MediaTek and Motorola.

The issue was classified as medium severity, requiring privileged access to exploit, and a patch was eventually issued by MediaTek. The timeline of events shows the steps taken from discovering the problem to its public disclosure. Sipgate encourages further research into the issue and has provided additional resources for interested parties.

(How Big Business killed the 'click-to-cancel' FTC rule, which would have saved)

The article discusses the recent failure of the Federal Trade Commission's (FTC) "click-to-cancel" rule, which aimed to make it easier for consumers to cancel automatically renewing subscriptions. This rule was designed to protect consumers from businesses that complicate cancellation processes, often leading to unexpected charges for services no longer wanted.

The rule was finalized after extensive development but was struck down by a conservative court just before it was set to take effect. The court ruled that the FTC did not follow proper procedure, even though there was significant public support for the rule.

Many businesses, fearing the impact of such regulations, fought against the rule, arguing that automatic renewals are beneficial for busy consumers. Despite the ruling's focus on legal technicalities, the article highlights that the FTC's efforts were aimed at addressing a known consumer abuse that affects many, particularly seniors and busy parents.

Ultimately, the article emphasizes the need for the FTC to revisit and potentially revive the rule to protect consumers from deceptive practices related to subscription services.

Sinking of the Rainbow Warrior

The sinking of the Rainbow Warrior was a covert operation by the French government on July 10, 1985. The Greenpeace ship was targeted due to its protests against French nuclear testing in the Pacific. French operatives planted bombs on the ship while it was docked in Auckland, New Zealand, resulting in its sinking and the drowning of a photographer named Fernando Pereira.

Initially, France denied involvement, but two French agents were caught and charged with crimes including murder. This incident caused a scandal in France, leading to the resignation of the French Defense Minister and a subsequent apology from France. The agents received prison sentences but spent only two years in a French Polynesian facility before being released.

The operation was motivated by France's desire to silence opposition to its nuclear tests, which were controversial in the Pacific region, especially after several nations declared the area a nuclear-free zone. The Rainbow Warrior had been actively campaigning against such testing and had a history of environmental activism.

Texas senators John Cornyn and Ted Cruz introduced a bill for the relocation, claiming it would honor Houston's role in space exploration.

Durbin raised concerns about the high costs associated with the move, stating that the proposed $85 million is insufficient, as the actual total could exceed $305 million, not including the $178 million needed for a new display facility in Texas. He also questioned whether Congress has the authority to remove artifacts from the Smithsonian, which legally owns Discovery.

Durbin introduced an amendment to block the transfer but later withdrew it, emphasizing the potential waste of taxpayer money in this effort. He urged his colleagues to consider the implications carefully.

(Million Times Million)

The article "Million Times Million" by Susam Pal discusses the difference between two systems for naming large numbers: the long scale and the short scale.

As a child, the author learned that in the long scale system, a million times a million equals a billion, while a million times itself three times is a trillion. Each term in this system clearly indicates how many times a million is multiplied. However, upon entering university and the tech world, the author discovered that the short scale system is more commonly used, where a million times a million is considered a trillion instead of a billion.

The article provides a comparison of the two systems, showing that while they agree on the value of a million, they differ significantly beyond that point. The author explains how to understand the short scale by relating it to multiplying thousands, although it is less intuitive than the long scale.

Despite now using the short scale, the author retains fond memories of the long scale due to its clear structure and the nostalgia of childhood learning.

Some arguments against a land value tax (2024)
(Some arguments against a land value tax (2024))

The land value tax (LVT) is often praised as an ideal tax because it can generate revenue without causing economic distortions and tends to tax wealthy landowners more. However, the author believes the LVT is overrated and its drawbacks are often overlooked.

Key criticisms of the LVT include:

  1. Disincentive for Land Development: The LVT discourages landowners from exploring new uses for their land. If they discover something valuable, their tax burden increases, which can deter investment in land development.

  2. Implicit Tax on Nearby Development: Improvements made on one parcel of land can raise taxes on adjacent plots, discouraging landowners from developing their properties.

  3. Limited Tax Base: The LVT has a narrow tax base, making it less effective as a revenue source. Efforts to modify the LVT to address its flaws could further reduce its viability.

  4. Complexity and Bureaucracy: Proposed fixes to the LVT could complicate its implementation, creating bureaucratic challenges and potential for manipulation in tax assessments.

  5. Potential for Erosion of Property Rights: Implementing a high LVT could undermine confidence in property rights, leading to reduced investment and economic growth.

  6. Disruption to Financial Plans: Many landowners have long-term financial strategies based on the assumption of stable land value. An LVT would disrupt these plans, imposing financial burdens unexpectedly.

  7. Misunderstanding of Land Speculation: The belief that the LVT would eliminate unproductive land speculation is challenged; landowners often have personal or strategic reasons for holding onto land that don’t align with the speculative model.

In conclusion, while the LVT has some merits, its limitations and practical challenges mean it is not the universal solution its proponents claim it to be. The author suggests viewing it as one flawed tool among many in tax policy, rather than a perfect answer to economic issues.

Australia is implementing new age checks for search engines like Google and Microsoft, starting December 27. This measure aims to restrict children's access to harmful content, such as pornography. The age verification will apply to users who are logged in, and companies must use various methods to confirm users' ages or risk fines of nearly $50 million for violations.

The age checks are part of a larger initiative to enhance online safety, particularly for young users, and are similar to rules already in place for social media. Experts express concerns about privacy and the effectiveness of these measures, noting that children could bypass restrictions using techniques like VPNs.

Several methods for age verification will be allowed, including photo ID checks, facial recognition, and using existing user data to estimate age. Critics argue these measures may not adequately protect children and could infringe on individuals' privacy rights. The government emphasizes its commitment to online safety while balancing user privacy.

asyncmcp – Run MCP over async transport via AWS SNS+SQS
(asyncmcp – Run MCP over async transport via AWS SNS+SQS)

Summary of Asyncmcp - Async Transport Layers for MCP

Overview: Asyncmcp is a tool designed to enhance the MCP (Model Context Protocol) by allowing it to work with asynchronous transport layers, particularly using queues. MCP is a protocol that helps applications provide context to large language models (LLMs).

Key Features:

  • Async Processing: Unlike traditional MCP servers that require immediate responses, asyncmcp allows requests to be processed in the background via internal queues. This means clients don’t have to wait for responses.
  • Transport Layer: It currently uses the SNS-SQS (Simple Notification Service - Simple Queue Service) for communication.

Installation:

  • Recommended: uv add asyncmcp
  • Alternative: pip install asyncmcp

Basic Setup:

  1. Server Configuration:

    • Set up a server that listens for MCP requests on a queue and sends responses to a topic using SNS and SQS.
  2. Client Configuration:

    • Set up a client that sends requests to a topic and listens for responses on a queue.

Limitations:

  • Message Size: SQS has a maximum message size limit (256KB standard, 2MB extended).
  • Response Timing: Responses may not be immediate due to the async nature.
  • Session Context: Managed by the server application, not the transport.
  • Message Ordering: Standard SQS does not guarantee the order of messages.

Testing and Contribution:

  • Unit tests can be run with uv run pytest.
  • Contributions to async MCP architectures are welcome.

Typeform was too expensive so I built my own forms
(Typeform was too expensive so I built my own forms)

A solopreneur runs a web design agency and creates open-source apps. Initially, they used Typeform for freelance project submissions, but it became too expensive as submissions increased. Google Forms looked unprofessional, so they decided to create their own forms, which led to a significant increase in submissions and inquiries. Happy with the results, they made the forms open-source and integrated AI features using Vercel AISDK. This allows for quick form generation and interactive analytics. They are sharing their progress publicly on their X account and are seeking feedback on the product.

US Court nullifies FTC requirement for click-to-cancel
(US Court nullifies FTC requirement for click-to-cancel)

A federal appeals court has canceled a "click-to-cancel" rule that required companies to make canceling services as easy as signing up. The rule, proposed by the Federal Trade Commission (FTC), was set to take effect on July 14 but was struck down because the court found that the FTC did not follow the proper legal process in creating the rule.

The judges acknowledged the FTC's goal to protect consumers from unwanted subscriptions but emphasized that the agency failed to conduct a necessary preliminary economic analysis. This analysis is required when a rule might have a significant economic impact. The FTC estimated the rule wouldn't exceed the $100 million threshold for such analysis, but a judge later indicated that it likely would.

Industry groups and businesses challenged the rule, arguing that they weren't given enough time to respond to the FTC's findings. The court's ruling highlighted concerns that failing to follow the correct procedures could lead to future issues with regulatory processes.

Republicans opposed the rule, with some arguing it was rushed and too broad. The FTC's former chair, Lina Khan, had stated that the rule was intended to prevent companies from making it difficult for consumers to cancel subscriptions.

Helm local code execution via a malicious chart
(Helm local code execution via a malicious chart)

Summary:

A security vulnerability was discovered in Helm (versions 3.18.3 and earlier) that could allow local code execution when updating dependencies. This occurs if a malicious Chart.yaml file is linked to a Chart.lock file. If the Chart.lock file is a symlink to a file that executes code (like a shell script), running the command to update dependencies can inadvertently execute harmful code.

This issue has a high severity rating (CVSS score of 8.5) and affects users who do not properly manage symlinks in their charts. Helm has resolved this issue in version 3.18.4.

Workaround: Ensure that the Chart.lock file is not a symlink before updating dependencies.

For more details, refer to Helm's security policy. The vulnerability was reported by Jakub Ciolek.

'Autofocus' specs promise sharp vision, near or far
('Autofocus' specs promise sharp vision, near or far)

A Finnish company called IXI has developed innovative glasses that use liquid crystal technology to automatically adjust vision correction for both near and far viewing. These glasses contain an eye-tracking feature that adapts to the wearer's needs, potentially making traditional bifocal or varifocal lenses obsolete. IXI aims to create eyewear that looks like regular glasses, addressing past failures of tech glasses like Google Glass.

As the population ages, conditions like presbyopia (difficulty focusing on close objects) and myopia (short-sightedness) are becoming more common, driving demand for advanced eyewear solutions. IXI's glasses are still in testing, with early versions facing quality issues, but improvements have been promising.

The glasses feature a small battery that lasts about two days and can be recharged overnight. Mr. Eiden, the CEO, has not yet announced a launch date or price. Other experts express cautious optimism, noting that while auto-focus glasses could help many, there are concerns about their performance compared to traditional options, especially for tasks requiring precise vision like driving.

Additionally, other companies are exploring technologies to slow the progression of eye conditions, such as myopia, but the future of fully automatic focusing glasses remains uncertain, with some questioning their widespread appeal compared to simpler solutions.
