LLMs Get a Memory Boost with HippoRAG

Large Language Models (LLMs) have quickly proven themselves to be invaluable tools for thinking. Trained on massive datasets of text, code, and other media, they can generate human-quality writing, translate languages, generate images, answer your questions in an informative way, and even write different kinds of creative content.  But for all their brilliance, even the most advanced LLMs have a fundamental constraint: their knowledge is frozen in time.  Everything they "know" is determined by the data they were trained on, leaving them unable to adapt to new information or learn about your specific needs and preferences.

To address this limitation, researchers developed Retrieval-Augmented Generation (RAG). RAG allows LLMs access to access datastores that can be updated in real-time. This access to dynamic external knowledge bases, allows them to retrieve relevant information on the fly and incorporate it into their responses. Since they tend to rely on keyword matching, however, standard RAG implementations struggle when a question requires connecting information across multiple sources —  a challenge known as "multi-hop" reasoning. 

Security Considerations When Building SaaS

There is no well-defined pattern or framework for building a managed SaaS. Building a well-managed SaaS involves solving a wide variety of problems. Some of these problems are common across different kinds of SaaS, and some are very specific to the SaaS. Examples of common problems are billing, analytics, metrics, and onboarding. Examples of problems that are different for every SaaS are provisioning (what resources should be provisioned when a new tenant onboards), data isolation, scaling, and performance needs. For the sake of this article, we will classify common problems as control plane problems, and different problems as data plane problems. 

This article briefly talks about the different models of providing tenant isolation and then delves into the security considerations of building a SaaS. 

How to Quickly Learn Coding and Land a Job in Tech

From the day I wrote my first Hello World program, it took me two years to land a job at Amazon and another two years to get into Google. That’s because I accomplished this without having a Computer Science degree or attending a boot camp. I made countless mistakes along the way which made my path to becoming a Software Engineer longer than it should have been. I spent countless hours watching YouTube tutorials and paid for numerous Udemy courses, only to find that they added no real value. If I could go back in time and undo all the things that didn't work, I would be in the exact same situation as today within six months of starting programming. That’s exactly why I am writing this helpful piece.

Today, I'll cut out all the unnecessary fluff and provide you with the quickest route from beginner to full-time Software Engineer.

What Is Reverse ETL? Overview, Use Cases, and Key Benefits

In the evolving landscape of data engineering, reverse ETL has emerged as a pivotal process for businesses aiming to leverage their data warehouses and other data platforms beyond traditional analytics. Reverse ETL, or “Extract, Transform, Load” in reverse, is the process of moving data from a centralized data warehouse or data lake to operational systems and applications within your data pipeline. This enables businesses to operationalize their analytics, making data actionable by feeding it back into the daily workflows and systems that need it most.

How Does Reverse ETL Work? 

Reverse ETL can be visualized as a cycle that begins with data aggregated in a data warehouse. The data is then extracted, transformed (to fit the operational systems' requirements), and finally loaded into various business applications such as a CRM, marketing platforms, or other customer support tools. These concepts can be further explored in this resource on the key components of a data pipeline

Cultivating A Mindset For Scaling Success

The foundation of scaling success lies in fostering the right mindset within your team. The case studies in Success at Scale highlight several critical mindsets that permeate the culture of successful organizations.

User-Centricity

Successful teams prioritize the user experience above all else.

They invest in understanding their users’ needs, behaviors, and pain points and relentlessly strive to deliver value. Instagram’s performance optimization journey exemplifies this mindset, focusing on improving perceived speed and reducing user frustration, leading to significant gains in engagement and retention.

By placing the user at the center of every decision, Instagram was able to identify and prioritize the most impactful optimizations, such as preloading critical resources and leveraging adaptive loading strategies. This user-centric approach allowed them to deliver a seamless and delightful experience to their vast user base, even as their platform grew in complexity.

Data-Driven Decision Making

Scaling success relies on data, not assumptions.

Teams must embrace a data-driven approach, leveraging metrics and analytics to guide their decisions and measure impact. Shopify’s UI performance improvements showcase the power of data-driven optimization, using detailed profiling and user data to prioritize efforts and drive meaningful results.

By analyzing user interactions, identifying performance bottlenecks, and continuously monitoring key metrics, Shopify was able to make informed decisions that directly improved the user experience. This data-driven mindset allowed them to allocate resources effectively, focusing on the areas that yielded the greatest impact on performance and user satisfaction.

Continuous Improvement

Scaling is an ongoing process, not a one-time achievement.

Successful teams foster a culture of continuous improvement, constantly seeking opportunities to optimize and refine their products.

Making Strategic Decisions for Scalability

Beyond cultivating the right mindset, scaling success requires making strategic decisions that lay the foundation for sustainable growth.

Technology Choices

Selecting the right technologies and frameworks can significantly impact scalability. Factors like performance, maintainability, and developer experience should be carefully considered. Notion’s migration to Next.js exemplifies the importance of choosing a technology stack that aligns with long-term scalability goals.

By adopting Next.js, Notion was able to leverage its performance optimizations, such as server-side rendering and efficient code splitting, to deliver fast and responsive pages. Additionally, the developer-friendly ecosystem of Next.js and its strong community support enabled Notion’s team to focus on building features and optimizing the user experience rather than grappling with low-level infrastructure concerns. This strategic technology choice laid the foundation for Notion’s scalable and maintainable architecture.

Ship Only The Code A User Needs, When They Need It

This best practice is so important when we want to ensure that pages load fast without over-eagerly delivering JavaScript a user may not need at that time. For example, Instagram made a concerted effort to improve the web performance of instagram.com, resulting in a nearly 50% cumulative improvement in feed page load time. A key area of focus has been shipping less JavaScript code to users, particularly on the critical rendering path.

The Instagram team found that the uncompressed size of JavaScript is more important for performance than the compressed size, as larger uncompressed bundles take more time to parse and execute on the client, especially on mobile devices. Two optimizations they implemented to reduce JS parse/execute time were inline requires (only executing code when it’s first used vs. eagerly on initial load) and serving ES2017+ code to modern browsers to avoid transpilation overhead. Inline requires improved Time-to-Interactive metrics by 12%, and the ES2017+ bundle was 5.7% smaller and 3% faster than the transpiled version.

While good progress has been made, the Instagram team acknowledges there are still many opportunities for further optimization. Potential areas to explore could include the following:

  • Improved code-splitting, moving more logic off the critical path,
  • Optimizing scrolling performance,
  • Adapting to varying network conditions,
  • Modularizing their Redux state management.

Continued efforts will be needed to keep instagram.com performing well as new features are added and the product grows in complexity.
