The author realized that their phone use had become excessive, spending about 11 hours a day on it with 95 pickups. As a marketer, they needed social media but wanted to control their usage. Traditional methods like app blockers didn't work for them. Instead of completely quitting social media, they aimed for a way to stay focused without constantly reaching for their phone.

To address this, they created the @hardestfocusapp, which encourages users to physically disengage from their phones to enhance focus. The app has simple rules: keep the phone face down, in a pocket, or locked away during focus time. If the phone is picked up, a loud warning sound alerts the user, and failing to put it back erases their progress, leveraging the fear of losing progress as motivation.

This approach has helped the author focus better, allowing them to confront their thoughts instead of escaping into their phone.

Summary of Developer's Block

Developer's block is similar to writer's block, where developers struggle to make progress on their projects. It can occur at the start of a new project or when working on an existing one.

Types of Developer's Block:

1. New Project Block: Developers often feel the pressure to create their best code. They may get blocked by trying to implement many best practices like testing, documentation, and version control all at once.
2. Existing Project Block: Developers may feel overwhelmed when new to a project or lose motivation after working on it for a while.

Causes of Developer's Block:

• Trying to rush understanding of a new codebase.
• Overwork or lack of motivation.

Tips to Overcome Developer's Block:

1. Take Time to Learn: Understand the project by experimenting with the code as a user and reading documentation.
2. Recognize Exhaustion: Take breaks and consider doing less mentally taxing tasks when tired.
3. Work Incrementally: Focus on small features or bugs initially, and refine your practices later.
4. Write Prototypes: Create quick prototypes to solve problems without worrying about perfection.
5. Start with Draft Documentation: Keep documentation simple at first and improve it later as users start engaging.
6. Avoid Premature Optimization: Don’t optimize code until necessary; focus on clarity first.
7. Release Early: Don’t wait for perfection; releasing early can provide valuable feedback.
8. Choose Your Battles: Don’t get sidetracked fixing dependencies or tooling issues; keep moving forward.

In conclusion, developers can experience blocks similar to writers, but by using specific strategies, they can regain momentum and continue their work effectively.

Summary: Optimizing Straddled Joins in Readyset

Readyset is a system designed to quickly serve queries using cached data. However, when it encounters a cache miss, it must execute queries directly against the base tables, which can slow down performance. This article focuses on improving the efficiency of straddled joins—queries where filters apply to both tables being joined.

Key Points:

1. Previous Optimization: Readyset moved from nested loop joins to hash joins to reduce the need for repeated scans. This improved performance but still faced issues with certain queries, especially those with low selectivity (like boolean flags).

2. Identifying Bottlenecks: Analysis revealed that data decompression and excessive disk reads contributed significantly to slow query execution times. Even after testing various compression methods, the main problem was found to be the large amount of data being read from disk.

3. Old Execution Strategy:

   • The previous method processed both sides of the join independently, leading to high I/O and memory usage.
   • For example, filtering a user by email (returning one row) while filtering orders by status (returning nearly all rows) was inefficient.

4. New Execution Strategy: Index Condition Pushdown (ICP):

   • The new approach evaluates the left-side filter first, then uses the result to narrow down the right-side lookups.
   • This method uses compound indexes to only retrieve the necessary rows, reducing unnecessary data reads.

5. Performance Benchmarking:

   • The old hash join method had low throughput and high latency due to inefficient data handling.
   • The new ICP method demonstrated a remarkable improvement, achieving over 450 times better throughput and latency.

Conclusion: The optimization of straddled joins using Index Condition Pushdown has significantly enhanced the performance of Readyset during cache misses, ensuring faster and more efficient query execution.

I'm unable to access external links directly, including the research paper you provided. However, if you can share the main points or key excerpts from the text, I would be happy to help you summarize them!

The text discusses how to efficiently process multiple records by using concurrency in programming, specifically in the Go language. Here are the key points:

1. Processing Records: Instead of handling records one by one (which can be slow), you can process them at the same time (concurrently) to save time.

2. Waitgroups: These are tools in Go that help manage multiple concurrent tasks. You use a waitgroup to keep track of how many tasks are running:

   • Add a count for each task you start.
   • Each task must signal that it's done by reducing the count.

3. Common Issues: If you forget to signal a task's completion, your program can "deadlock" or crash. This happens when the count goes negative if more tasks finish than were started.

4. Goleak Library: This library helps find and fix issues with goroutine leaks.

5. Go Version 1.25 Improvements: The latest version of Go simplifies handling goroutines. You can now use wg.Go to automatically manage the count, making it easier to work with concurrent tasks.

6. Kubernetes Enhancements: In version 1.25, Go automatically manages CPU settings for applications running in Kubernetes, which simplifies deployment.

The author plans to explore more features of the sync package in future posts.

A co-worker found several d4d4 instructions in disassembled ARM code that were always unreachable. This was surprising, as d4d4 is a relative branch instruction. The investigation began with a simple function that returned, yet had a d4d4 instruction after it. The initial thought was that it was for alignment, but further tests showed that adding more functions removed the d4d4 entirely.

When three functions were used, the d4d4 returned, suggesting it was used for aligning object files, specifically to ensure 32-bit boundaries between them. It was determined that the d4d4 was not inserted by the compiler but by the linker (LLD), which rounds up the end of object files using this instruction instead of a more benign option like zeroes.

Comparing with the GNU linker revealed it uses zeroes for alignment instead. The conclusion is that LLD's use of d4d4 as a trap instruction is misleading since it acts as a conditional jump rather than halting execution. This behavior seems like a bug, and there’s a suggestion to report it. The analysis also uncovered that the choice of d4 was arbitrary and not optimal for a trap instruction.

Summary

The text discusses a project called Anubis, which aims to protect websites from AI crawlers by requiring users to solve a computational challenge, akin to Bitcoin mining. When a user visits a site using Anubis, they need to perform SHA-256 hash calculations to prove they are human, which is said to make crawling websites too costly for AI vendors.

The author, who hosts a blog and has experienced issues with aggressive crawlers, questions the effectiveness of Anubis. They argue that AI vendors have ample computing resources, making the challenge easy for them to overcome, while it poses a significant burden for regular users with limited computing power.

The author breaks down the math behind the challenge, showing that solving it for every website using Anubis would take a negligible amount of time and cost almost nothing for those with substantial resources. Complaints from users with limited access to computing resources are noted, highlighting the potential unfairness of the system.

Additionally, the article mentions other historical anti-spam solutions and provides a workaround for users to bypass the Anubis challenge without using a desktop browser. The author concludes that while the challenge seems to add a layer of protection, it primarily complicates access for genuine users rather than effectively deterring crawlers.

I was interested in arranging objects along a spherical helix path and read some articles about it. This led me to revisit parametric equations, and I created a visualization to show what I learned. You can check it out here: Moving Objects in 3D. I'd love to hear your thoughts!

Astronomers have discovered a small new moon around Uranus, named S/2025 U1, using NASA's James Webb Space Telescope. This moon is only about 6 miles (10 kilometers) in diameter, making it too small to be detected by previous missions like Voyager 2. With this discovery, the total number of known moons orbiting Uranus has increased to 29.

S/2025 U1 orbits Uranus at a distance of about 35,000 miles (56,000 km) from its center and follows a circular path, suggesting it formed in its current location. The moon is part of a group of small satellites that orbit within the paths of Uranus's larger moons, most of which are named after characters from Shakespeare's plays.

The discovery highlights the advanced capabilities of the James Webb Space Telescope and emphasizes that there is still much to learn about Uranus's complex system of moons and rings. Scientists believe there may be even more undiscovered moons, given that S/2025 U1 is the smallest and faintest known so far.

Uranus has 13 rings made of darker materials, which are more difficult to observe than those of other gas giants like Jupiter and Saturn. The findings from this research could help reveal the intricate relationships between Uranus's moons and its rings.
