System Design Interview with a Meta Staff Engineer: Designing a Task Scheduler Recently, I had the opportunity to participate in a mock system design interview with an E6 Staff Engineer from Meta. The topic was designing a Task Scheduler - a relatively simple problem meant to ease him back into the rhythm of technical interviews after years of not participating in the job-hopping scene. Despite this, his strong fundamentals and sharp thought process were clearly evident, as he covered most of the key aspects of the problem. view full answer in bugfree.ai: https://lnkd.in/gWbBcmdV #SystemDesign #InterviewPreparation #TaskScheduler #Meta #TechInterviews #Engineering

What Happened After Google Retrofitted Memory Safety Onto Its C++ Codebase?: Google's transistion to Safe Coding and memory-safe languages "will take multiple years," according to a post on Google's security blog. So "we're also retrofitting secure-by-design principles to our existing C++ codebase wherever possible," a process which includes "working towards bringing spatial memory safety into as many of our C++ codebases as possible, including Chrome and the monolithic codebase powering our services." We've begun by enabling hardened libc++, which adds bounds checking to standard C++ data structures, eliminating a significant class of spatial safety bugs. While C++ will not become fully memory-safe, these improvements reduce risk as discussed in more detail in our perspective on memory safety, leading to more reliable and secure software... It's also worth noting that similar hardening is available in other C++ standard libraries, such as libstdc++. Building on the successful deployment of hardened libc++ in Chrome in 2022, we've now made it default across our server-side production systems. This improves spatial memory safety across our services, including key performance-critical components of products like Search, Gmail, Drive, YouTube, and Maps... The performance impact of these changes was surprisingly low, despite Google's modern C++ codebase making heavy use of libc++. Hardening libc++ resulted in an average 0.30% performance impact across our services (yes, only a third of a percent) ... In just a few months since enabling hardened libc++ by default, we've already seen benefits. Hardened libc++ has already disrupted an internal red team exercise and would have prevented another one that happened before we enabled hardening, demonstrating its effectiveness in thwarting exploits. The safety checks have uncovered over 1,000 bugs, and would prevent 1,000 to 2,000 new bugs yearly at our current rate of C++ development... The process of identifying and fixing bugs uncovered by hardened libc++ led to a 30% reduction in our baseline segmentation fault rate across production, indicating improved code reliability and quality. Beyond crashes, the checks also caught errors that would have otherwise manifested as unpredictable behavior or data corruption... Hardened libc++ enabled us to identify and fix multiple bugs that had been lurking in our code for more than a decade. The checks transform many difficult-to-diagnose memory corruptions into immediate and easily debuggable errors, saving developers valuable time and effort. The post notes that they're also working on "making it easier to interoperate with memory-safe languages. Migrating our C++ to Safe Buffers shrinks the gap between the languages, which simplifies interoperability and potentially even an eventual automated translation."

Anyscale: New Optimized Runtime for Ray, Kubernetes Operator https://lnkd.in/gfTxqiYr Anyscale, the fast-emerging company behind the open source AI compute engine Ray, revealed a list of new products and services at its annual user conference in San Francisco earlier this week. Among them: An optimized Ray runtime, created in response to customer feedback, and a Kubernetes operator. The three-day Ray Summit event, which ended Thursday and attracted nearly 1,500 developers, also brought together leading experts from OpenAI, a16z, Meta, and Runway, among others, to discuss the latest innovations in the development of AI at scale. Ray is a unified AI development platform that enterprises deploy to scale their AI and machine learning workloads across any infrastructure. The company claims that Ray enables developers to instantly scale applications from a laptop to the cloud without the cost or expertise of building complex infrastructure. Current users of Anyscale’s Ray AI platform include Airbnb, Instacart, OpenAI, Netflix, Uber, Canva, Pinterest, and Spotify. Anyscale announced a slew of platform advancements, including an architectural rebuild that makes Ray GPU-native. This means it now enables high performance in inter-GPU communication for workloads such as distributed training and model serving. The 5-year-old, San Francisco-based company also announced RayTurbo, an optimized Ray runtime meant to improve performance and efficiency for AI workloads. The company introduced the Anyscale Operator for Kubernetes, which enables users to optimize their AI workloads and Kuberay API server investments on the infrastructure they control. Anyscale also updated its Anyscale Governance Suite, a set of observability tools designed to manage compute resources and control AI sprawl. Ray ‘Enables Any AI Workload’ “From Day One, we designed Ray for building and scaling AI applications,” Ion Stoica, co-founder of Anyscale, told The New Stack. “By unifying infrastructure via a single, flexible framework, Ray has enabled any AI workload, from multimodal data processing to model training to model serving and beyond.” RayTurbo, Stoica said, was created in response to comments from Ray users. “One piece of feedback we’ve heard consistently is that our users need to maximize their resource utilization and minimize cost,” Stoica said. “Now, with RayTurbo, we’ve built on top of the industry’s de-facto standard AI compute engine to make it faster, more cost-effective and more reliable. RayTurbo is now available on the Anyscale platform to all our users.” Other items unveiled at the conference included Ray Data, a library for processing unstructured data at scale, new direct integrations connecting the Anyscale platform to Kubernetes for AI/ML development, and tools for enterprise governance and observability. Access to Newly Supported Data Formats With the general availability of Ray Data, the company said, all users will have access to newly...
