How I learn in Obsidian // Keeping up with tech trends | Summary and Q&A

TL;DR

Join a developer advocate as they use Obsidian and other tools to learn about eBPF monitoring, consolidate information, and create visual representations of their knowledge.

Key Insights

• 🤔 There are various methodologies for note-taking, but personal preference and adaptability to individual needs can be effective.
• 🔎 Readwise and its new product, Reader, are useful tools for researching and consolidating information.
• 📚 Creating a system of tags and workspaces helps organize and process notes efficiently. ⏰ Prioritizing and starting with the newest notes can ensure relevance in the learning process.
• 🔬 eBPF (Extended Berkeley Packet Filter) is a topic of interest for the Developer Advocate, focusing on monitoring and observability.
• 🧪 Instrumentation and eBPF are two different approaches to monitoring, with eBPF offering ease of use and efficiency.
• 👥 Popular companies such as Netflix use eBPF for monitoring microservices, emphasizing its resource efficiency and overhead.
• 📈 eBPF monitoring contributes to the trend of unified observability and continuous profiling for better system understanding.

Transcript

• There are a lot of methodologies out there so it's easy to get methodology fatigue. Like what exactly is a permanent note? How do you know when a note is atomic enough? How do you decide when a note is evergreen versus seedling or whatever? I don't know if it's just my own chaotic personality but my tendency is to learn those methodologies and th... Read More

Questions & Answers

Q: How does the advocate use Readwise and Obsidian to gather and organize information on eBPF monitoring?

The advocate uses Readwise to import articles and resources, and then leverages Obsidian to create notes, add citations, and organize the information in a hierarchical structure.

Q: What are the advantages of eBPF monitoring mentioned in the video?

The video mentions that eBPF monitoring is highly efficient, consuming less than 1% of CPU and memory resources. It also allows for continuous delivery as eBPF programs can be shipped and changed independently without affecting kernel code. Additionally, eBPF monitoring offers enhanced security features.

Q: How does the advocate differentiate between instrumentation and eBPF monitoring?

The advocate explains that instrumentation is the traditional approach to monitoring, where an instrumentation agent sits on components and passes information. On the other hand, eBPF monitoring works at the kernel level and eliminates the need for multiple agents, resulting in higher efficiency and security.

Q: How does the advocate create visual representations of the knowledge they gain?

The advocate uses Excalidraw to create simplified visual diagrams of eBPF monitoring and instrumentation. They embed these diagrams in their notes using Obsidian's advanced slides plugin.

Q: What is the advocate's approach to note-taking and knowledge consolidation?

The advocate emphasizes that their note-taking process is dynamic and constantly evolving. They consolidate information from various resources, organize it in a way that makes sense to them, and are open to updating and changing their notes as they learn more. They also encourage viewers to find their own approach and discard methods that don't work for them.

Summary & Key Takeaways

• The video showcases a developer advocate using Readwise and Obsidian to learn about eBPF monitoring.

• The advocate demonstrates their process of organizing, consolidating, and visualizing the information they gather.

• The importance of monitoring, the difference between instrumentation and eBPF, and the advantages of eBPF monitoring are discussed.
