Understand docker
Docker allows building and running applications in isolated containers. It provides a way to package applications with all their dependencies and ship them as standardized units called containers. Containers are more lightweight than virtual machines and allow applications to run anywhere regardless of the underlying infrastructure. Docker uses containerization at the operating system-level rather than hardware virtualization to deliver software in packages called containers. This allows applications to be easily deployed and scaled across computing infrastructure.
Mocloudos - Feather-weight Cloud OS developed within
14 man-days
Mocloudos is a feather-weight cloud OS developed within 14 man-days using mruby, a lightweight Ruby implementation, and Xen virtualization. It allows running multiple mruby VMs and extends functionality through mrbgems. The developer was able to create a working alpha version integrating features like FAT filesystem, DHCP, sockets and a key-value store within the targeted 14 day period.
Docker Fundamentals
Docker allows users to run applications in isolated containers using images from a registry similar to an app store. It simplifies deploying applications by allowing them to run without installing dependencies on the host machine. The docker architecture includes a client, host with docker daemon, images used to create containers which run applications, and a registry to store images. Users can install docker, search for images, run containers from images, check running containers, kill containers, and share data between containers and hosts.

Storage based snapshots for KVM VMs in CloudStack
This document discusses storage-based snapshots for KVM VMs in CloudStack. It describes how CloudStack can leverage underlying storage providers' capabilities to take consistent snapshots of VMs and their disks while the VMs are running, regardless of disk format. This is done by freezing the VM, taking asynchronous snapshots of its disks, then unfreezing the VM. This provides faster, more space-efficient snapshots compared to CloudStack's default VM snapshot implementation for qcow disks. The technique works with various storage providers like NFS, Ceph, and StorPool.
Conair

Server 2016 sneak peek
Windows Server 2016 introduces several new features including software defined storage, Hyper-V improvements, automation enhancements, and Nano Server. Storage Spaces Direct enables hyper-converged infrastructure, Storage Replica allows for volume replication, and Resilient File System provides improved integrity and performance. Hyper-V gains features like cluster rolling upgrades and shielded VMs. Automation is focused on a graphical authoring experience and Linux/Azure support. Nano Server offers a headless deployment optimized for cloud workloads.
OpenVZ Linux Containers
The talk is about operating system virtualization technology known as OpenVZ. This is an effective way of partitioning a Linux machine into multiple isolated Linux containers. All containers are running on top of one single Linux kernel, which results in excellent density, performance and manageability. The talk gives an overall description of OpenVZ building blocks, such as namespaces, cgroups and various resource controllers. A few features, notably live migration and virtual swap, are described in greater details. Results of some performance measurements against VMware, Xen and KVM are given. Finally, we will provide a status update on merging bits and pieces of OpenVZ kernel to upstream Linux kernel, and share our plans for the future.

High performance Serverless Java on AWS- GoTo Amsterdam 2024
Java is for many years one of the most popular programming languages, but it used to have hard times in the Serverless community. Java is known for its high cold start times and high memory footprint, comparing to other programming languages like Node.js and Python. In this talk I'll look at the general best practices and techniques we can use to decrease memory consumption, cold start times for Java Serverless development on AWS including GraalVM (Native Image) and AWS own offering SnapStart based on Firecracker microVM snapshot and restore and CRaC (Coordinated Restore at Checkpoint) runtime hooks. I'll also provide a lot of benchmarking on Lambda functions trying out various deployment package sizes, Lambda memory settings, Java compilation options and HTTP (a)synchronous clients and measure their impact on cold and warm start times.

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.

Mutation Testing for Task-Oriented Chatbots
Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.
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).

Editor's Notes
- FCD Create/Modify Extend the size of an FCD. Rename an FCD. Updating the SPBM policy associated with an FCD. Convert an FCD from thin provisioned to thick provisioned. Attaching a tag to an FCD. FCD Attach Can be attached to VMs FCD Delete Deletion of an FCD that is not attached to a VM Deletion of an FCD that is attached to a VM FCD Snapshot Can be snapshotted as part of a VM Can be snapshotted itself (attached/detached from VM) VM snapshot does not create FCD-specific snapshot FCD Encryption Encryption of FCDs is not available today, but is something we are planning to have available very soon. FCD Max Volume Size The FCD API does not dictate the maximum. The maximum volume size is defined by the underlying storage. FCD Cloning The FCD API support cloning of FCDs. FCD Migration The FCD API supports the relocating (Storage vMotion) of an FCD to another datastore.
