Season 2 Finale

Saison 2 · Épisode 15

jeudi 8 août 2024 • Durée 23:14

As we approach the finale of our second season, it's time for another recap.

Could we shed some light on the current state of Rust's usage in the industry? What has changed in our perception of Rust in production since our last season?

While more companies started to embrace Rust, some of the magic of Rust's early days is gone. I expect more ripple effects as the community clashes with the industry's demands.

This episode takes on a more somber tone, as we peer into the massive tech debt we have accumulated as an industry. And in the dark: a faint glow, a narrow golden path that points us towards a more hopeful future.

System76 with Jeremy Soller

Saison 2 · Épisode 14

jeudi 25 juillet 2024 • Durée 01:33:36

Many devs dream of one day writing their own operating system. Ideally in their favorite language: Rust. For many of us, this dream remains just that: a dream.

Jeremy Soller from System76, however, didn't just contribute kernel code for Pop!_OS, but also started his own operating system, RedoxOS, which is completely written in Rust. One might get the impression that he likes to tinker with low-level code!
In this episode of Rust in Production, Jeremy talks about his journey. From getting hired as a kernel developer at Denver-based company System76 after looking at the job ad for 1 month and finally applying, to being the maintainer of not one but two operating systems, additional system tools, and the Rust-based Cosmic desktop. We'll talk about why it's hard to write correct C code even for exceptional developers like Jeremy and why Rust is so great for refactoring and sharing code across different levels of abstraction.

Tweede Golf with Folkert de Vries

Saison 1 · Épisode 5

jeudi 8 février 2024 • Durée 01:13:30

Have you ever wondered how computers stay in sync with the time? That is the
responsibility of the Network Time Protocol (NTP). Around since 1985, NTP is one
of the oldest protocols still in use on the internet and its reference
implementation, ntpd, written in C, is still widely used today.

That's a problem. C is a language that is not memory safe, and ntpd has had its
share of security vulnerabilities. Here is a list of CVEs.

As part of Project Pendulum, Folkert de Vries and his colleagues from Tweede
Golf have been working on a Rust implementation of NTP. I sit down with Folkert
to talk about the project, the challenges they faced, and the benefits of using
Rust for this kind of project.

Along the way, we learn about funding open source projects, the challenges of
establishing a new implementation of a protocol, and all sorts of other
interesting things that might or might not be related to NTP.

PubNub with Stephen Blum

Saison 1 · Épisode 2

jeudi 28 décembre 2023 • Durée 58:24

In this episode, we are joined by Steven, the CTO of PubNub, a company that has developed an edge net messaging network with over a billion connected devices. Steven explains that while message buses like Kafka or RabbitMQ are suitable for smaller scales, PubNub focuses on the challenges of connecting mobile devices and laptops at a web scale. They aim to provide instant signal delivery at a massive scale, prioritizing low latency for a seamless user experience. To achieve this, PubNub has architected their system to be globally distributed, running on AWS with Kubernetes clusters spread across all of Amazon's zones. They utilize GeoDNS to ensure users connect to the closest region for the lowest latency possible. Steven goes on to discuss the challenges they faced in building their system, particularly in terms of memory management and cleanup. They had to deal with issues such as segmentation faults and memory leaks, which caused runtime problems, outages, and potential data loss. PubNub had to invest in additional memory to compensate for these leaks and spend time finding and fixing the problems. While C was efficient, it came with significant engineering costs. As a solution, PubNub started adopting Rust, which helped alleviate some of these challenges. When they replaced a service with Rust, they observed a 5x improvement in memory and performance. Steven also talks about choosing programming languages for their platform and the difficulties in finding and retaining C experts. They didn't consider Java due to its perceived academic nature, and Go didn't make the list of options at the time. However, they now have services in production written in Go, though rewriting part of their PubSub bus in Go performed poorly compared to their existing C system. Despite this, they are favoring Rust as their language of choice for new services, citing its popularity and impressive results. The conversation delves into performance considerations with Python and the use of PyPy as a just-in-time compiler for optimization. While PyPy improved performance, it also required a lot of memory, which could be expensive. On the other hand, Rust provided a significant boost in both memory and performance, making it a favorable choice for PubNub. They also discuss provisioning, taking into account budget and aiming to be as close to what they need as possible. Kubernetes and auto scaling with HPAs (Horizontal Pod Autoscaling) are used to dynamically adjust resources based on usage. Integrating new services into PubNub's infrastructure involves both API-based communication and event-driven approaches. They use frameworks like Axiom for API-based communication and leverage Kafka with Protobuf for event sourcing. JSON is also utilized in some cases. Steven explains that they chose Protobuf for high-traffic topics and where stability is crucial. While the primary API for customers is JSON-based, PubNub recognizes the superior performance of Protobuf and utilizes it for certain cases, especially for shrinking down large character strings like booleans. They also discuss the advantages of compression enabled with Protobuf. The team reflects on the philosophy behind exploring Rust's potential for profit and its use in infrastructure and devices like IoT. Rust's optimization for smaller binaries is highlighted, and PubNub sees it as their top choice for reliability and performance. They mention developing a Rust SDK for customers using IoT devices. The open-source nature of Rust and its ability to integrate into projects and develop open standards are also praised. While acknowledging downsides like potential instabilities and longer compilation time, they remain impressed with Rust's capabilities. The conversation covers stability and safety in Rust, with the speaker expressing confidence in the compiler's ability to handle alpha software and packages. Relying on native primitives for concurrency in Rust adds to the speaker's confidence in the compiler's safety. The Rust ecosystem is seen as providing adequate coverage, although packages like libRDKafka, which are pre-1.0, can be challenging to set up or deploy. The speaker emphasizes simplicity in code and avoiding excessive abstractions, although they acknowledge the benefits of features like generics and traits in Rust. They suggest resources like a book by David McCloyd that focuses on learning Rust without overwhelming complexity. Expanding on knowledge sharing within the team, Stephen discusses how Rust advocates within the team have encouraged its use and the possibilities it holds for AI infrastructure platforms. They believe Rust could improve performance and reduce latency, particularly for CPU tasks in AI. They mention the adoption of Rust in the data science field, such as its use in the Parquet data format. The importance of tooling improvements, setting strict standards, and eliminating unsafe code is highlighted. The speaker expresses the desire for a linter that enforces a simplified version of Rust to enhance code readability, maintainability, and testability. They discuss the balance between functional and object-oriented programming in Rust, suggesting object-oriented programming for larger-scale code structure and functional paradigms within functions. Onboarding Rust engineers is also addressed, considering whether to prioritize candidates with prior Rust experience or train individuals skilled in another language on the job. Recognizing the shortage of Rust engineers, Stephen encourages those interested in Rust to pursue a career at PubNub, pointing to resources like their website and LinkedIn page for tutorials and videos. They emphasize the importance of latency in their edge messaging technology and invite users to try it out.
