Build a Rails REST web service using a separate API namespace
 
16:09
This talk follows on from demonstrating the REST client for the CSA application (https://youtu.be/xUuMq7kPhiw) and the talk in class. I build a separate API namespace the provides CSA as a RESTful web service. You can obtain both the solution and the client from my Github repository with the command: git clone -b csa-server-for-rest-client https://github.com/chriswloftus/csa csa-server-for-rest-client You will also find the REST client under the folder csa-rest-client. Note that the example requires the installation of Ruby, Rails and ImageMagick. This video is aimed at the module SE31520 at Aberystwyth University Computer Science Dept (https://www.aber.ac.uk/en/cs/)

RubyConf 2017: How to load 1m lines of Ruby in 5s by Andrew Metcalf
 
31:27
How to load 1m lines of Ruby in 5s by Andrew Metcalf Applications written in Ruby, Python and several other popular dynamic languages become very slow to boot as they grow to millions of lines of code. Waiting to reload code in development becomes a major frustration and drain on productivity. This talk will discuss how we reduced the time to boot a service at Stripe from 35s to 5s and the static analysis tools we built along the way.

Docker: Port and Volume Mapping
 
16:53
Understanding port and volume mapping is perhaps one of the most important thing in learning docker. Since docker runs inside of a container we need to understand how our resources like disk space and ports are managed with in the container. Volumes are docker's way of managing storage. There are a few ways we can connect volumes in docker. One of the ways is to just name a volume and have docker manage our volume for us. In this episode we explore how docker manages volumes. Since docker services can't be accessed by the host OS we need to understand how port mapping works. This will allow us to access the service running on a port. Not all kinds of process needs port mapping however services that your app need to interact with such as postgres, redis, elasticsearch or memcache usually do. #ZACKSIRI http://twitter.com/zacksiri #SOCIAL https://vimeo.com/channels/docker http://www.codemy.net http://www.facebook.com/codemy.net http://www.twitter.com/codemynet

RailsConf 2018: Access Denied: the missing guide to authorization in Rails by Vladimir Dementyev Rails brings us a lot of useful tools out-of-the-box, but there are missing parts too. For example, for such essential tasks as authorization we are on our own. Even if we choose a trending OSS solution, we still have to care about the way to keep our code maintainable, efficient, and, of course, bug-less. Working on Rails projects, I've noticed some common patterns in designing access systems as well as useful code techniques I'd like to share with you in this talk.

RubyConf 2017: Packing your Ruby application into a single executable by  Minqi Pan
 
28:35
Packing your Ruby application into a single executable by Minqi Pan Recent languages like Go compiles a project into a nice executable, why can't good ol' Ruby? We have built an packer for Ruby to do just that. It is 100% open-source, and can produce executables for Windows, macOS and Linux individually. By packing, distributing Ruby apps are made extremely easy, additionally with intellectual property protection. Auto-updating is also made easy, in that the executable only needs to download and replace itself. So, how we did it? How to use it? What goes under the hood? What future will this bring to Ruby? That's what will be unraveled in this talk!

Docker on windows-1
 
06:52
Docker is an open-source project that automates the deployment of applications inside software containers, by providing an additional layer of abstraction and automation of operating-system-level virtualization on Linux.[2] Docker uses resource isolation features of the Linux kernel such as cgroups and kernel namespaces to allow independent "containers" to run within a single Linux instance, avoiding the overhead of starting and maintaining virtual machines.[3] The Linux kernel's support for namespaces mostly[4] isolates an application's view of the operating environment, including process trees, network, user IDs and mounted file systems, while the kernel's cgroups provide resource isolation, including the CPU, memory, block I/O and network. Since version 0.9, Docker includes the libcontainer library as its own way to directly use virtualization facilities provided by the Linux kernel, in addition to using abstracted virtualization interfaces via libvirt, LXC (Linux Containers) and systemd-nspawn.[5][6][7] According to industry analyst firm 451 Research, "Docker is a tool that can package an application and its dependencies in a virtual container that can run on any Linux server. This helps enable flexibility and portability on where the application can run, whether on premise [sic], public cloud, private cloud, bare metal, etc."[8] Docker implements a high-level API to provide lightweight containers that run processes in isolation.[9] Building on top of facilities provided by the Linux kernel (primarily cgroups and namespaces), a Docker container, as opposed to a traditional virtual machine, does not require or include a separate operating system.[8] Instead, it relies on the kernel's functionality and uses resource isolation (CPU, memory, block I/O, network, etc.) and separate namespaces to isolate the application's view of the operating system. Docker accesses the Linux kernel's virtualization features either directly through the provided libcontainer library (which is available since Docker 0.9), or indirectly via libvirt, LXC (Linux Containers) or systemd-nspawn.[7][10] By using containers, resources can be isolated, services restricted, and processes provisioned to have an almost completely private view of the operating system with their own process ID space, file system structure, and network interfaces. Multiple containers share the same kernel, but each container can be constrained to only use a defined amount of resources such as CPU, memory and I/O. Using Docker to create and manage containers may simplify the creation of highly distributed systems by allowing multiple applications, worker tasks, and other processes to run autonomously on a single physical machine or across a spectrum of virtual machines. This enables the deployment of nodes as resources are available or needed, thus providing platform as a service (PaaS)–style deployment and scaling for systems like Apache Cassandra, MongoDB or Riak, and simplification of the creation and operation of task or workload queues and other distributed systems.[11][12] Docker can be integrated into various infrastructure tools, including Amazon Web Services,[13] Ansible,[14] CFEngine,[15] Chef,[16] Google Cloud Platform,[17] IBM Bluemix,[18] Jelastic,[19] Jenkins,[20] Microsoft Azure,[21] OpenStack Nova,[22] OpenSVC,[23] Puppet,[24] Salt,[25] and Vagrant.[26] The Cloud Foundry Diego project integrates Docker into the Cloud Foundry PaaS.[27] The GearD project aims to integrate Docker into the Red Hat's OpenShift Origin PaaS.[28] Solomon Hykes started Docker as an internal project within dotCloud, a platform as a service company,[29] with initial contributions by other dotCloud engineers including Andrea Luzzardi and Francois-Xavier Bourlet. Jeff Lindsay was also involved as an independent collaborator. Docker represents an evolution of dotCloud's proprietary technology, which itself built on earlier open-source projects such as Cloudlets. Docker was released as open source in March 2013.[9] On March 13, 2014, with the release of version 0.9, Docker dropped LXC as the default execution environment and replaced it with its own libcontainer library written in Go language.[5][10] As of April 13, 2015, the project had over 20,700 GitHub stars (making it the 20th most starred GitHub project), over 4,700 forks, and nearly 900 contributors.[30]

Easiest Way to Learn XML
 
03:05
What is the easiest way to learn XML? You could go to the MSDN dot Microsoft dot com site and go to their section on Learning XML. They have information on not only how to use XML but all the versions and variants of it. Including how to use MSXML, the XML version Microsoft controls. It tells you how to use Visual Studio’s XML tools like XML editor and XML schema explorer. Of course Microsoft tells you how to use Microsoft’s XML editor. If you’re so bum on Microsoft, go to w3schools dot com. It has in depth tutorials on using XML. I need the beginner stuff more than I need the in depth material. It has everything from what XML stands for to how to code in XML, to code samples to explanations of XML namespaces. As long as its resources are up to date and relevant. XML is not updating and making prior info obsolete like Ruby on Rails did, nor is it evolving so fast that five year old tutorials are irrelevant. In fact, the W3schools dot com site has info on how to use XML with CSS. CSS is part of HTML5. I’d consider that pretty relevant. It also tells you how to use XML with JavaScript and CDATA. I’ve never heard of CDATA, but JavaScript is an HTML5 standard these days. You could use the XMLmaster dot org site to get the basics of XML all the way up to the advanced skill sets. How advanced? It is all integrated with ads to prepare for the XML master exam. I suppose that’s reasonable. SitePoint dot com’s section on a really good introduction to XML, is a good introduction to XML. You did not say really twice. Really? It is a good intro, though the meat is in the book the site is selling. Any other resources I should look into? XMLfiles.com has a lot of references on XML, from XML DOM to XML RSS to XHTML. The last of which is a torture to use even compared to HTML5. So hit Youtube’s XML tutorial for beginners video by PortnovSchool and learn how to create an XML file. And unlike a lot of the other sites, the content is free, and you do not care about Adsense ads. What do you think of TechEdGuru’s Youtube channel? It is not something to avoid if you’re trying to learn about programming, but he does not do much on XML. Any other ways to get free XML lessons? Go to a Microsoft Open Office XML course and tell them you think the rival Open Document format is better. Collect all the books they throw at you, then run.

Docker for Ops: Docker Networking Deep Dive, Considerations and Troubleshooting - Docker Track
 
01:10:07
Docker is an open platform for developers and system administrators to build, ship and run distributed applications. With Docker, IT organizations shrink application delivery from months to minutes, frictionlessly move workloads between data centers and the cloud and can achieve up to 20X greater efficiency in their use of computing resources. Inspired by an active community and by transparent, open source innovation, Docker containers have been downloaded more than 700 million times and Docker is used by millions of developers across thousands of the world’s most innovative organizations, including eBay, Baidu, the BBC, Goldman Sachs, Groupon, ING, Yelp, and Spotify. Docker’s rapid adoption has catalyzed an active ecosystem, resulting in more than 180,000 “Dockerized” applications, over 40 Docker-related startups and integration partnerships with AWS, Cloud Foundry, Google, IBM, Microsoft, OpenStack, Rackspace, Red Hat and VMware.

Creating Effective Images
 
43:13
Abby Fuller - Software Engineer/Technical Evangelist, AWS Sick of getting paged at 2am and wondering "where did all my disk space go?" This has actually happened to me, and you can learn from my mistakes! New Docker users often start with a stock image in order to get up and running quickly, but that isn't always the right answer. Creating efficient images is overlooked, but important. Beyond saving resources, using minimal images also delivers important security benefits: include only what you need, and not a whole runtime that might have security vulnerabilities. In this session, I'll talk about how to create effective images, and lessons I've learned from running containers in production at a number of startups. I'll also cover topics like "how do layers work?", and some things you should think about when creating your images, such as; choosing or creating the right base image; ordering your statements correctly for caching; using RUN statements conservatively; and cleaning up as you install dependencies. I'll also address best practices; both at a high level (like using dual container builds - one to build an artifact, and one to build from base); and some language-specific best practices, for example, tips and tricks for creating containers for Node.js vs Go To illustrate these points, we'll cover: * How layers work? * Choosing a base image vs. creating your own with scratch. * The basics for building minimal images: ordering statements correctly for caching awesomeness, using RUN conservatively, clean up as you go. * High level best practices for Linux containers (in general, and some language specific examples). * Let's talk about Windows! High level best practices for Windows container images. * Good vs. not so good Dockerfile examples * Docker Image Scanning * Looking forward to the future for even more optimization: Unikernels for Docker, Nix.

I Can’t Believe It’s Not A Queue: Using Kafka with Rails by Terence Lee Your existing message system is great, until it gets overloaded. Then what? That's when you should try Kafka. Kafka's designed to be resilient. It takes the stress out of moving from a Rails monolith into a scalable system of microservices. Since you can capture every event that happens in your app, it's great for logging. You can even use Kafka's distributed, ordered log to simulate production load in your staging environment. Come and learn about Kafka, where it fits in your Rails app, and how to make it do the things that message queues simply can't. Help us caption & translate this video! http://amara.org/v/JUpN/

How We Built a Framework at Twitter to Solve Service Ownership & Improve Infrastructure Utilization
 
28:46
How We Built a Framework at Twitter to Solve Service Ownership & Improve Infrastructure Utilization at Scale [I] - Vinu Charanya, Twitter Twitter is powered by thousands of microservices that run on our internal Cloud platform which consists of a suite of multi-tenant platform services that offer Compute, Storage, Messaging, Monitoring, etc as a service. These platforms have thousands of tenants and run atop hundreds of thousands of servers, across on-prem & the public cloud. The scale & diversity in multi-tenant infrastructure services makes it extremely difficult to effectively forecast capacity, compute resource utilization & cost and drive efficiency. In this talk, I would like to share how my team is building a system (Kite - A unified service manager) to help define, model, provision, meter & charge infrastructure resources. The infrastructure resources include primitive bare metal servers / VMs on the public cloud and abstract resources offered by multi-tenant services such as our Compute platform (powered by Apache Aurora/Mesos), Storage (Manhattan for key/val, Cache, RDBMS), Observability. Along with how we solved this problem, I also intend to share a few case-studies on how we were able to use this data to better plan capacity & drive a cultural change in engineering that helped improve overall resource utilization & drive significant savings in infrastructure spend. About Vinu Charanya Vinu Charanya is a Senior Software Engineer at Twitter where she works in the Compute Platform building Twitter’s internal cloud infrastructure management platform. She is also a core team member of Women who code, a non-profit organization dedicated to inspiring women to excel in technology careers. She is also a part-time teacher and a mentor helping students learn iOS and Android development at CodePath. Vinu received her Masters in Computer Science and Engineering from University at Buffalo, where she worked on the PhoneLab Testbed research group under Prof. Geoff Challen and Prof. Steve Ko.

Kubernetes in production - blue-green deployment, auto scaling and deployment automation
 
53:10
by Paul Bakker Kubernetes is a great tool to run (Docker) containers in a clustered production environment. There are also a few things that Kubernetes doesn't solve though. When deploying often to a production environment we need fully automated blue-green deployments, which makes it possible to deploy without any downtime. We also need to handle external HTTP requests and SSL offloading. This requires integration with a load balancer like Ha-Proxy. Another concern is (semi) auto scaling of the Kubernetes cluster itself when running in a cloud environment. E.g. partially scale down the cluster at night. Although Kubernetes doesn't provide these things out of the box, it does provide an API that can be used to make all of this happen. Tools for automated blue-green deployments and scaling a Kubernetes cluster were developed as part of the Cloud RTI project which is developed in open source. In this technical deep dive you will learn how to setup Kubernetes together with other open source components to achieve a production ready environment that takes code from git commit to production without downtime.

RailsConf 2016 - Crushing It With Rake Tasks By Barrett Clark
 
29:48
Crushing It With Rake Tasks By Barrett Clark Although bundle exec rake db:migrate is probably the single biggest killer feature in Rails, there is a lot more to rake. Rails offers several rake tasks to help with everyday project management, like redoing a migration because you changed your mind on one of the columns, clearing your log files because they get so big, and listing out the TODOs and FIXMEs. What's even more awesome that all that is that you can create your own rake tasks. Got a tedious command-line process? Write a rake task for it!

CppCon 2018: Herb Sutter “Thoughts on a more powerful and simpler C++ (5 of N)”
 
01:39:09
http://CppCon.org — Presentation Slides, PDFs, Source Code and other presenter materials are available at: https://github.com/CppCon/CppCon2018 — Perhaps the most important thing we can do for C++ at this point in its evolution is to make sure we preserve its core strengths while also directing its evolution in ways that make it simpler to use. That is my own opinion at least, so this talk starts with a perspective question: What “is C++,” really? The language continues to evolve and change; as it does so, how can we be sure we’re picking C++ evolutionary improvements that not only don’t lose its “C++-ic” qualities, but make it a better C++ than ever? At recent CppCons, I’ve spoken about several of my own personal C++ evolution efforts and experiments, and why I think they’re potentially important directions to explore for making C++ both more powerful and also simpler to use. The bulk of the talk is updates on two of these: 1. Lifetime and dangling: At CppCon 2015, Bjarne Stroustrup and I launched The C++ Core Guidelines in our plenary talks. In my part starting at 29:06, I gave an early look at my work on the Guidelines “Lifetime” profile, an approach for diagnosing many common cases of pointer/iterator dangling at compile time, with demos in an early MSVC-based prototype. For this year’s CppCon, I’ll cover what’s new, including: • use-after-move diagnoses • better support for the standard library out of the box without annotation • more complete implementations in two compilers: in MSVC as a static analysis extension, and in a Clang-based implementation that is efficient enough to run during normal compilation • the complete 1.0 Lifetime specification being released on the Guidelines’ GitHub repo this month I’ll summarize the highlights but focus on what’s new, so I recommend rewatching that talk video as a refresher for background for this year’s session. 2. Metaclasses: In my CppCon 2017 talk, I gave an early look at my “metaclasses” proposal to use compile-time reflection and compile-time generation to make authoring classes both more powerful and also simpler. In this case, “simpler” means not only eliminating a lot of tedious boilerplate, but also eliminating many common sources of errors and bugs. For this year, we’ll cover what’s new, including: • an update on the Clang-based implementation, which now supports more use cases including function parameter lists • new examples, including from domains like concurrency • an updated P0707 paper, with more links to working examples live on Godbolt, being posted in the next few weeks for the pre-San Diego committee mailing — Herb Sutter Microsoft Author, and chair of the ISO C++ committee. — Videos Filmed & Edited by Bash Films: http://www.BashFilms.com

Quickstart AngularJS - How to make your browsers Smarter 4432

Quickstart AngularJS - How to make your browsers Smarter What is AngularJS? AngularJS is a JavaScript MVC framework developed by Google that lets you build well structured, easily testable, and maintainable front-end applications. And Why Should I Use It? If you haven’t tried AngularJS yet, you’re missing out. The framework consists of a tightly integrated toolset that will help you build well structured, rich client-side applications in a modular fashion—with less code and more flexibility. AngularJS extends HTML by providing directives that add functionality to your markup and allow you to create powerful dynamic templates. You can also create your own directives, crafting reusable components that fill your needs and abstracting away all the DOM manipulation logic. It also implements two-way data binding, connecting your HTML (views) to your JavaScript objects (models) seamlessly. In simple terms, this means that any update on your model will be immediately reflected in your view without the need for any DOM manipulation or event handling (e.g., with jQuery). Angular provides services on top of XHR that dramatically simplify your code and allow you to abstract API calls into reusable services. With that, you can move your model and business logic to the front-end and build back-end agnostic web apps. Finally, I love Angular because of its flexibility regarding server communication. Like most JavaScript MVC frameworks, it lets you work with any server-side technology as long as it can serve your app through a RESTful web API. But Angular also provides services on top of XHR that dramatically simplify your code and allow you to abstract API calls into reusable services. As a result, you can move your model and business logic to the front-end and build back-end agnostic web apps. In this post, we’ll do just that, one step at a time.
