All You Need to Know About Kustomize
•
0 likes•24 views
Kustomize is a Kubernetes native configuration management tool that allows customizing application configurations without templating. It takes over existing application manifests and is built into the kubectl command. Kustomize introduces an overlay pattern to customize resources through a kustomization file. Other configuration tools like Helm have template languages that can be ugly due to templating and conflict with other tools, while Kpt automates editing but requires functions for transformations. Kustomize aims to provide a simpler way to customize configurations and can integrate with tools like ArgoCD. Challenges include dealing with incompatible upstream changes and difficulties reviewing pull requests.

Hitchhiker's guide to Cloud-Native Build Pipelines and Infrastructure as Code
As more and more application deployments move to the cloud the scale and complexity becomes harder to manage. Instead of a handful of large instances, you might have many smaller instances, so there are many more things you need to provision. Because of this cloud vendors provide API abstraction of their compute, storage, network and other platform services. In this talk I present a guide to provision these services, such as a Kubernetes cluster, using infrastructure as code and deploy your applications through cloud-native build pipelines. Get to know the concepts behind these DevOps practices and come hear which tools to use like Terraform and Oracle Container Pipelines to automate these laborious tasks on the Oracle Cloud Infrastructure.

Intro to InnerSource
Slides from Daniel Figucio, Field CTO at Github APAC from his talk at Wellington DevOps Group on 6 September, 2022
https://www.meetup.com/wellington-devops-group/events/287973178/
Adopting this modern approach to software development can be transformative—enabling collaboration and fostering the creation of high quality code. But understanding the principles, and potential challenges, is critical to success.
Many companies use the word “innersource” to describe how their engineering teams work together on code. Innersource is a development methodology where engineers build proprietary software using best practices from large-scale open source projects, like Kubernetes or Microsoft’s Visual Studio Code.
Large-scale open source projects require coordination and teamwork across thousands of contributors. The most successful ones are driven by a vision for their future, in addition to day-to-day user needs: speed, reliability, and functionality. The scale at which these operate can teach us a few lessons—and help your business build better software, faster using innersource.

Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.
