As the number of developers on a project, the number of projects in an Organization, or the complexity of a single project increases, it also becomes increasingly difficult to keep our development environments operational. From changing dependencies and differing server versions to running completely different operating systems specially windows machines of FrontEnd team, keeping the process of getting a running development environment sane and repeatable is non-trivial.
Getting the development environments identically setup can be a huge undertaking. On top of that, some people use Mac while others Use Linux or Windows. Before you know it, developers will be throwing computers through walls exhausted from constantly configuring and configuring. Windows machine devs yelling WTF is this Imagemagick , people using Mac asking which is better macports vs homebrew vs fink.
Vagrant solves all of this by introducing a common configuration format and workflow for describing and building development environments repeatably across Mac OS X, Windows, or Linux.
Il message-passing per più di dieci anni è stata la soluzione di riferimento per affrontare le sfide e l'implementazione di un sistema distribuito: problemi di rete, forte accoppiamento fra nodi, eterogeneità delle applicazioni (diversi linguaggi di programmazione).
Questo talk tratterà le soluzioni per costruire un'architettura orientata ai servizi (SOA) ed effettuare message-passing in maniera performante ed affidabile; ripercorreremo insieme i concetti e le tecnologie principali che sono alla base dei sistemi distribuiti.
Instant LAMP Stack with Vagrant and PuppetPatrick Lee
Do you enjoy installing and configuring Apache, PHP, and MySQL every time you reinstall your OS or switch to a new machine? Neither do I. And we never have to do it again. Vagrant can use the VirtualBox API and configuration defined in Puppet to spin up a development VM in a couple of minutes. And it's really easy to do. I'll start with the simplest possible example and work up to a cluster of VM's. Feel free to bring your laptop and follow along.
OSDC 2015: Kris Buytaert | From ConfigManagementSucks to ConfigManagementLoveNETWAYS
In the beginning there was CFEngine, and the learning curve was high, then came Puppet , Chef and the learning curve was still high.
Now we have Ansible , for everyone that wasn't smart enough to learn the original tools. Or wasn't that the problem ?
For some people Infrastructure as Code became a goal alone, not caring about the infrastructure, Junior people wanted to learn Puppet, but forgot about the service they were configuring. Too Complex, Too much effort, .. And then containers came.
GraalVM is a recent development from Oracle. It's supposed to replace HotSpot just-in-time compiler technology, but actually, it's much more. From a JIT compiler to a language implementation framework for JVM to a native image generator, it's going to change how software for JVM is written and run. During the presentation, we will explore the new possibilities and benefits provided by GraalVM.

Infrastructure as data with Ansible: systems and cloud
deployment and management for the lazy developer
Abstract: Great programmers and sysadmins are lazy people: rightly,
they prefer avoiding manual, time consuming and error-prone tasks such
as installing and configuring a Linux/Apache/Tomcat cluster for the
tenth time.
Ansible, an infrastructure (server, cloud) deployment automation &
configuration both powerful AND simple (in most cases simpler than
shell scripts and maven poms!), will make developers and it staff more
productive and effective.

Site performance is really about rendering. When, where and how fast your web page or application renders is critical. These provide insights into the member experience. After all, that's the goal - provide a great member experience. Using Webpagetest with help from Chrome's DevTools Timeline, we'll use visualization progression charts and explore this aspect of site performance.
Micronaut is a new JVM-based, full-stack framework for building modular, easily testable microservice applications with Java, Kotlin, and Groovy.
In this live-coding session, you will see how fast you can start developing “natively” cloud-native microservices with Micronaut. You will learn about the reactive support, testing, http-client, service discovery, fallback, and GraalVM support.
An overview of chatbots for self-service devops. This presentation includes architecture and examples of using a botkit slackbot to automate deployments on openshift kubernetes on AWS
Testing Java Microservices: From Development to ProductionDaniel Bryant
Testing microservices is challenging. Dividing a system into components (à la microservices) naturally creates inter-component dependencies, and each service has its own performance and fault-tolerance characteristics that need to be validated during development, the QA process, and continually in production. Attend this meetup to learn about the theory, techniques, and practices needed to overcome this challenge. You will:
• Get an introduction to the challenges of testing distributed microservice systems
• Learn how to isolate tests within a complex microservice ecosystem
• Hear about several tools for automating vulnerability and security scanning for code, dependencies, and deployment artifacts
This is session is on WebAssembly with Rust. In which first we will discuss web assembly in detail and how the WebAssembly will change the dimension of web development followed with the Demo and see some Live applications working on WebAssembly.
One of the cornerstones in Agile development is fast feedback. For engineering, "fast" means "instantly" or "in 5 minutes", not "tomorrow" or "this week". Your engineering practices should ensure that you can answer yes to most of the following questions:
- Do we get all test results in less than 5 minutes after a commit?
- Is our code coverage more than 75% for both front-end and back-end?
- Can we start exploratory testing in less than 15 minutes after a commit?
- Do all our tests pass more than 90% of our commits?
This talk will give you practical advice on how to get to "yes, we get fast feedback".
MongoDb scalability and high availability with Replica-SetVivek Parihar
One of the much awaited features in MongoDB 1.6 is replica sets, MongoDB replication solution providing automatic failover and recovery.
MongoDB High Availabiltity with Replica Sets

Mobile First Approach - The key to cross platform interface designVivek Parihar
Mobile first design has been taking centrestage in the consumer internet media stage. This makes it extremely important for the Design/development community to understand the intricacies, pitfalls and the right practices about it.
From my own experiments, I have elicited few interesting protcols and practices for the same. The presentation aims to share the results of the successful experiments and open up discussion on what the best way forward can be.
Outline of the talk:
1. Understanding the need for mobile sites
2. Going through the basics of a fluid interface; differences between responsive sites and mobile sites
3. Bottom up approach - first build minimum features for the smaller screens. It helps keep the lean approach alive.
4. Optimized content structuring - limited size on small screens calls for relevant and optimized content layouts
5. Ensuring the right experience on small screen devices via optimized front end

This presentation is on MongoDb basic , it is short and covered a lot of enlightened point which is really helpful for the people who are novice in MongoBb. Here we not only discuss the importance of MongoBb, but also a different scenario where SQL and No SQL (i.e No Only SQL) is good and each one possess their own importance. Also some info about 10Gen's support for MongoBb users.
My presentation given to the London MongoDB User Group on the importance of indexes. It is a small case study into how indexes improved the performance of several pages on our site.
10 Deployments a day - A brief on extreme release protocolsVivek Parihar
A reflection on how we migrated from an era of production deployments once a week to more than 10 deployments a day. The story of transforming a mere sys-admin to super sophisticated DevOps team, armed with multiple tools, scripts and plugins for achieving automations, accuracy and invincible agility. As we continue on our endeavor for further improvisation, I believe its worth sharing the experience with community. Tentative topics outline:
1.Arming teams for their transformation to DevOps from mere sys-admins.
2.Killing manual deployments (manual deployment->capistrano->webistrano)
3.Automation (for daily backups,monitoring applications and servers deploying dependencies)
4.Saving up time on setting up new instances(using golden image).
5.Using LDAP to maintain servers with public key(avoiding individual logins to every server makes it less messy)
6.Using Puppet for instantiating multiple servers at once.
7.Commissioning our own Cloud Infrastructure.

Beyond Local Development w/Kalabox (SFDUG July 2015)Alec Reynolds
Web developers have an Age Old Problem: to work on websites, we need to install and run web server technology (databases, HTTP servers, etc.) on our local computers. In a time when the tools we use to develop and run websites are growing at an exponential rate, we need an updated toolkit that goes beyond "local development."
Enter Kalabox.
Kalabox is a single tool that gives developers all the tools they need to code, test, and go live with their websites. This presentation covers some of the basic problems that Kalabox tries to solve, as well as some of the basic features of Kalabox.

Take home your very own free Vagrant CFML Dev Environment - Presented at dev....Gavin Pickin
Vagrant is a great solution for providing all of your devs a standard dev environment, but like all the other great technology out there, you have to learn it, and then implement it.
Not anymore, this session will give you a well used, documented Vagrant Setup, with the flexibility to use it for all of your future dev projects too. Learn how this Vagrant Environment is setup, and how to extend it. Kill the learning curve, and spin it up today.
This setup is being used by several devs, on several projects, and has simple flexibility built in. Drop your repos in the main folder, follow simple conventions, and add a small amount of configuration and be able to spin up your environment in minutes. This setup can configure a simple welcome page, configure the web server and cfml engine mappings, datasources, web server settings per site, host entries, and much more.
As great as this sounds, nothing is ever perfect, learn how some assumptions left me looking silly, and owing another developer a meal, and how I resolved that issue and made this vagrant setup even better.

It could be a dream, but luckily it's a reality that could be yours.
I was invited by the Hatchery+ to give a presentation and workshop on building products - a brief overview on modern web apps, tech stacks, languages, frameworks, services, APIs and more.
DevOps is a large part of a company of any size. In the 9+ years that I have been a professional developer I have always taken an interest in DevOps and have been the "server person" for most of the teams I have been a part of. I would like to teach others how easy it is to implement modern tools to make their everyday development and development processes better. I will cover a range of topics from "Stop using WAMP/MAMP and start using Vagrant", "version control isn't renaming files", "Automate common tasks with shell scripts / command line PHP apps" and "From Vagrant to Production".

A Git Workflow Model or Branching StrategyVivek Parihar
Git branching model or Workflow. A Git Workflow is a recipe or recommendation for how to use Git to accomplish work in a consistent and productive manner. Git workflows encourage users to leverage Git effectively and consistently. Git offers a lot of flexibility in how users manage changes. This ppt is based on The Git Flow. It was created by Vincent Driessen in 2010 and it is based in two main branches with infinite lifetime:
master — this branch contains production code. All development code is merged into master in sometime.
develop — this branch contains pre-production code. When the features are finished then they are merged into develop.
Note: slides produced from the blog post of https://nvie.com/posts/a-successful-git-branching-model/
Programming languages and concepts by vivek pariharVivek Parihar
This presentation is concerned with the study of programming language paradigms, that is the various systems of ideas that have been used to guide the design of programming languages. These paradigms are realized to a greater or lesser extent in various computer languages, although the design of a given language may reflect the influence of more than one paradigm.
Case Study to build a tablet based app that is a shopping assistant.Vivek Parihar
Case Study:
You need to build a tablet based app that is a shopping assistant. When I enter the store, I pick it up and it has the digital catalogue with current inventory status based on live POS feed (so it does not show anything that is stocked out). The digital catalogue is searchable using conversational interface (assume you have the NLP algo available for this). When I choose an item, it shows me similar items (which are identified based on image similarity analysis, you have an algo for it but you need to deploy it for weekly refresh of the similarity dataset) and items which go well together (based on mining past data, you have an algo for it but you need to deploy it for weekly refresh of the dataset). It also has an AR layer which can guide me to the item, and show what is nearby in same isle etc. and give instant offers etc.
1. What is broad architecture for this and choice of tech stack?
2. How will you structure this as a project and what will be team responsibility allocation and timelines?
Too much into acquisition without fixing retention problem: Let's Re-prioriti...Vivek Parihar
As traditional marketing mentality "whatever happens after an acquisition is for everyone else to figure out" is reckless and wrong. Most companies are significantly more likely to be focused on acquisition than retention (44% vs. 16% for companies). As retention is usually cheaper and much low-hanging fruit. So instead of using it as AARRR, you should use it as RARRA. RARRA: the re-prioritized funnel
In general, RARRA is nothing more than a reordered list of AARRR for the modern, saturated and highly competitive app store reality.
First, you need to focus on Retention, then on Activation. Then move on to Referral and Revenue. The last step should be Acquisition. The very last step. Not the first one.
Devops for beginners is basically for the developers who really want to jumps towards DevOps processes and tools. Guide will give basic about what is cloud and virtualisation ?

Centralized logging system using mongoDBVivek Parihar
This talk will cover the need of a centralized logging system, showcasing the architecture of the system. Also, I talk about how we ended up building this centralized logging system, What was the need for such a system, what problems we faced, how MongoDB fits into this and what others can learn from this.
I also covered some how can we use mongoDB to make our logging system for realtime analytics and alerting system
. The major use case of this system it to keeping track of meaningful events. This could be -:
1. How many users registered ?
2. How many registrations fails ?
3. Most occurred errors while doing something.
4. Realtime Analytics and Alerts
5. Identifying the possible threats.

These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

And Me!
3. Agenda
● Why You Are Doing What You Are Doing?
● What’s Wrong With It?
● What Are My Options ?
● The Future You Ask ?
● Limitations or Known Gotchas?
● Our Take
4. ● You have to develop an awesome application.
● The app is huge, challenging and most importantly cool
● Team of 10 - 15 includes Backend/Frontend Devs, Quality Analysts
etc.,
● You Need Rails , Node.js , Imagemagick , FFmpeg, Ruby Gems ,
MYSQL and even MongoDB.
1. Typical Project Scenario
Why You Are Doing… What You are Doing...
5. 2. Setting up the development environment.
Why You Are Doing… What You are Doing...
● Ideally you’re going to want all 15 people on the team working on this
app to have identical development environments.
● You provide a readme file to each of the developer’s to start setting
up their machines.
● Even on the same team people can have different machine setups
and tool choices (Mac, Linux , Windows ).
● Problem ?
6. Even with a provide full fledge documentation for how to setup
the development environments can be a huge task.
eg: Windows machine yelling WTF is this Imagemagick , people
using Mac asking which is better macports vs homebrew vs fink.
What’s wrong with It?
7. ● How long does it usually take for a
new team member to be ready to
work on your team ?
● What you do now ? Give him/her the
again a readme doc ?
● It might take a day or two or worse
existing team members time is also
wasted in setting up the machine for
him/her.
● Problem again ?
1. New team member on-boarding
What’s wrong with It?
8. 2. Working on Multiple Projects
What’s wrong with It?
● Developers and QA working on different
projects , require different versions of
ruby , libraries , gems etc., installed on
their machine.
● How do you solve that ?
9. ● Wait? Don’t we do that already? Isn’t that what RVM, NPM,MAVEN
and BUNDLER are for?
● They do great things for keeping Ruby versions separate and project
gems in isolation.
● But they do nothing to help with application dependencies like
Oracle, Passenger,Apache ,ImageMagick, Qt(for WebKit) etc., etc
● Problem Again ?
What’s Wrong With It?
11. Who has not heard
this sentence?
Mostly during bug fixing , It's so common that each dev either it is
FrontEnd / Application Developer they keep saying and yelling at you
13. “ C’mon, what is this, two thousand ten? It’s the freakin’
future, man. Instructions for humans are nowhere near as
good as instructions for computers. Humans make mistakes,
misunderstand, and are generally not as fast as computers
when doing this kind of thing. We can tell the computer to do
stuff on our behalf while we watch videos of adorable
animals! ”
-Riley
What’s The Future You Ask ?
14. ● It solves a very huge problem of “works on
my machine” by very common concept, that
is creating your own private VMs(virtual
machines)
● In simple words what I understood from
being a DevOps is taking Snapshot of your
instance or VM.
What’s The Future You Ask ?
15. Those who don't know about Snapshot's, here are some quotes from
Stackoverflow
"Snapshots : An exact capture of what a volume looked like at a
particular moment in time, including all it's data. You could have a
volume, attach it to your instance, fill it up with stuff like Rails , Node.js,
Imagemagick and FFmpeg(video conversion libraries), ruby gems
MySQL etc, then snapshot it, but keep using it.
What’s The Future You Ask ?
16. ● Using Vagrant we can build development environments repeatedly
across Mac OS X, Windows, or Linux.
● A developer’s box kinda becomes this sketchy place where you just
really want to wash your hands after using it.
● Vagrant provides a great way to keep all of that nicely contained, per
project, and away from your precious development machine.
What’s The Future You Ask ?
17. ● The cool thing about Vagrant is that you can create a full dev
environment, with every tool/library required for development already
installed and ready to use.
● Package this up (and the VM's configuration) into a single file that you
can use as a template.
● You have one single file that you distribute to your other team
member and everyone can then use the same environment in couple
of minutes without any hustle :) to build and break.
● New team member on-boarding? No Problem now.
What’s The Future You Ask ?
18. ● If you do it right, you can even leverage your provisioning information
to provision your operational or test systems
● No more hunting down weird dependency problems or debugging.
● Push Vagrant to the limits, it supports the concept of multi-VMs By
using multi-VM support.
● Single vagrant up command, bring up an entire stack of clustered
nodes
19. ● Vagrant interacts with VirtualBox mmm…. It might be the problem.
● If you run the virtual network editor on Windows, the forwarded ports
will suddenly stop working.. Happens sometimes :P
○ Run vagrant reload and things will begin working again.
● In some cases reported Vagrant is slow in Windows Machines….
○ Just Enabling DNS proxy in NAT mode
Limitations or Known Gotchas?
20. By choosing to use Vagrant, our projects and organization gain
some immediate benefits:
● Every developer is now working within identical development
environments. This eliminates a large portion of “works on my
machine” issues.
● No more READMEs per project, or having to ask DevOps for help, or
simply being lost.
Our Take
21. ● Easy nuclear option
● When things go wrong, it can be
really disheartening to reinstall
your operating system.
● Instead put Vagrant to work !
● Take a coffee break and you’ll
be back up and running in no
time.
Our Take
22. ● The development environments are now sandboxed within virtual
machines.
● First, the environments can replicated or run on any machine, it
doesn't matter if it is Linux, Mac OS X, Windows etc.
● Multiple projects with potentially conflicting dependencies can even
run side-by-side.
Our Take
