2. Jellyfin as a Spotify alternative
Total comment counts : 51
Summary
After leaving Spotify, the author experimented with various music players but found them lacking in features and usability. They developed a web-based music player but faced limitations while traveling. Eventually, they settled on Apple Music, which, despite being cumbersome, provided offline access. A recommendation led them to Jellyfin, a self-hosted solution that met their needs. Though self-hosting may seem daunting, the setup was straightforward, and additional apps allowed for offline music access. The author now uses Jellyfin with the Finamp app for daily listening.

The author expresses frustration with a service that had sign-in issues and misleading instructions regarding the use of a PIN. They attempted to use the BYO plan with an existing openrouter API key but encountered model pack limitations and configuration challenges, particularly with Gemini 2.5 Pro. The distinction between the FOSS and BYO plans is unclear, and the author prefers not to store data on a server, finding the paid plan less valuable as a result.
5. Concurrency in Haskell: Fast, Simple, Correct
Total comment counts : 16
Summary
After a decade in embedded systems, the author now writes Haskell, discovering its strengths in real-time systems where performance and correctness are critical. Haskell’s concurrency model utilizes green threads managed by the runtime, enhancing efficiency without traditional debugging frustrations. Utilizing the async package allows for smooth thread management and cancellation. The author highlights Software Transactional Memory (STM) as a powerful feature for safe communication between threads, enabling atomic transactions without common concurrency pitfalls. Haskell effectively combines performance with developer-friendly abstractions, making it a compelling choice for concurrent programming.
Top 1 Comment Summary
In Haskell, exceptions can be thrown to other threads, and asynchronous exceptions are crucial for maintaining modularity due to the language’s purity. Simons Marlow and Peyton Jones argue that semi-asynchronous methods can break synchronization and are incompatible with purely functional languages like Concurrent Haskell, where most operations are functional. Polling a global flag contradicts functional programming principles. Consequently, fully-asynchronous exceptions are both necessary and safe in functional settings, while they pose risks in imperative contexts. For further insights, Marlow and Jones’s paper offers a detailed exploration of this topic.

The implications of the decision could reshape the industry landscape and impact how online advertising operates.
7. Passing planes and other whoosh sounds
Total comment counts : 17
Summary
Oona Räisänen explores the sound of airplanes overhead, challenging the assumption that the ‘whoosh’ is solely due to the Doppler effect. She analyzes the sound using a time-frequency spectrogram, revealing a combination of sounds that create a unique interference pattern, similar to ‘comb filtering.’ Her hypothesis suggests we perceive both the direct sound and a delayed echo from the ground, with a significant time difference impacting how the sound is heard. Variations could depend on the observer’s height and the ground surface, necessitating further testing in different environments.

The author speculates on the impact of multiple engine sounds from airliners, questioning if sound wave superposition affects the listener’s experience during a fly-by. They suggest that the spatial arrangement of engines and the listener’s position could influence the perceived sound. The theory could be tested by observing if the sound effect changes when the plane flies directly overhead.

Summary
The Battle of Solferino in June 1859, pivotal for Italian independence, is now largely forgotten. Yet, its impact was profound, notably igniting humanitarian movements. Henry Dunant, a Swiss businessman, witnessed the battlefield’s horrific aftermath, prompting him to act by organizing local aid and medical care for wounded soldiers, regardless of their side. His experiences inspired him to publish a memoir highlighting the suffering, ultimately laying the groundwork for international humanitarian law. Dunant’s vision for compassionate care transformed responses to wartime injuries and emphasized humanity’s shared bond.

9. An intro to DeepSeek’s distributed file system
Total comment counts : 15
Summary
3FS (Fire-Flyer File System) is a distributed filesystem launched by DeepSeek as part of their open-source initiative. It enables applications to interact seamlessly with files distributed across multiple machines, providing high data capacity, fault tolerance, and redundancy. The system consists of four main node types, including a management node (Mgmtd) for monitoring and configuration, a meta node for handling filesystem operations, and storage nodes for data management. 3FS utilizes the CRAQ protocol for strong consistency and fault tolerance, ensuring effective data replication and handling of read/write operations.
Top 1 Comment Summary
The article discusses S3FS, a scale-out metadata filesystem that utilizes FoundationDB for metadata storage. It compares S3FS with other distributed file systems like Collosus, Tectonic, ADLSv2, and HopsFS, noting their various metadata storage solutions. S3FS is notable for its support of a FUSE client and NVMe storage, reducing Disk I/O bottlenecks in training pipelines. The author, who has worked on HopsFS, highlights HopsFS’s tiered storage approach, using NVMe for recent data and S3 for archiving.
Top 2 Comment Summary
The author emphasizes evaluating parallel distributed file systems through theoretical limits, efficiency, and practical deployment challenges. While systems like Lustre can scale storage indefinitely, efficiency calculations show that running 3FS in AWS is only 12-30% cheaper than FSx for Lustre, and managing clusters adds complexity. There’s skepticism about the ease of configuring these systems for large deployments. Ultimately, the need for efficient data management is crucial for AI companies, prompting DeepSeek to develop custom solutions. The author hopes Archil can provide simpler defaults for users without the hassle of cluster management.
10. Adipose tissue retains an epigenetic memory of obesity after weight loss
Total comment counts : 16
Summary
The article explores the concept of “obesogenic memory” in adipose tissues, revealing that significant weight loss does not eliminate cellular transcriptional and epigenetic changes caused by obesity. Using single-nucleus RNA sequencing, researchers demonstrated that both human and mouse adipocytes retain these changes, which impair their function and contribute to rapid weight regain, a phenomenon known as the “yo-yo” effect. The findings suggest that persistent epigenetic alterations in cells may underlie long-term obesity challenges, indicating potential targets for improving weight management and health outcomes in obesity treatment.

Adipocytes, or fat cells, increase in number when gaining weight. However, when losing weight, these cells do not die off; instead, they simply shrink in size by releasing their lipid stores.
Top 2 Comment Summary
The author reflects on their weight loss struggles, noting the perception of a “slow metabolism” that makes losing fat more challenging than gaining it. They mention receiving a video on fat adaptation, which claims to help the body improve fat burning, and express curiosity about its credibility, questioning the balance between factual science and “bro science.” The author intends to investigate the topic further to see if it could aid in their weight loss efforts.
