Cloud Bending Using the Latest Terraform
Terraform is an open-source infrastructure as code software tool created by HashiCorp. It enables us to define and provision infrastructure using a high-level configuration language HCL and lets us build richer, more complex infrastructure, but with a much less complex configuration. This intermediate level (300) talk focuses on the upcoming features of latest Terraform 0.12 release and things we should be aware of before upgrading to latest release.

Evidence Extraction, Investigation and Evaluation Environment – A DIY Experiment
There are a lot of really cool things out there in the open source space that have been designed to do one thing, and to do it well. Sometimes you need to consolidate all of the outputs of these things into something greater (hopefully) than the sum of its parts. The project is currently live and ongoing, so I don’t want particularly to quote exactly what tools are going to be used at the end of the day but they are likely to include : ElasticSearch, Tika, The Sleuth Kit, Exiftool, EWFlib and a few of the standard UNIX tools (file for example), and will build a distributed digital forensics environment leveraging older hardware in parallel to speed up the digital forensics process.Provisional talk description

How I Accidentally Became an Electronics Engineer (Actually I Didn’t)
AWS, DNS, K8S. We’re being exposed to IT so much at work that some of us just call it a day and refrain from any hobbyist computer stuff in our private time and maybe you have also more important responsibilities to take care of such as family. But maybe you do still from time to time try to pursuit a fun project. If so, and if you know the “bottom drawer syndrome” (enthusiastically started something, first lost time, then interest, now stored things away out of sight) or if can relate to “buy first, think of a purpose for it later”, this talk is for you.
My motivation was to bring both purpose and order to two such gadgets in my drawer, a Raspberry Pi and a LED stripe and in my search I accidentally ended up designing a PCB, the PiStripe uHAT. In this talk I will recap and take you along on my journey during which I had to leave my usual comfort zone, that is software, and delve into hardware and electronics. Don’t worry, this is not going to be a electronics 101 course. Instead I want to remedy some unwarranted fears and encourage you to look beyond the end of your (software) nose as electronics illiteracy did not stop me either from being successful as proven by my PCB which I’ll bring along (and maybe give away one or two).

Keeping PostgreSQL Up With the Cool Kids
PostgreSQL has a long history of innovation, extensibility and adaptability, it was conceived that way. Over recent years we’ve seen a plethora of new data technologies. At the same time PostgreSQL has evolved to offer comparable features. This talk will look at a number of features which PostgreSQL offers to keep up with the ever evolving data landscape. I want to show how PostgreSQL is a truly general purpose database which can do way more than SQL92 via your ORM. From document storage, time-series data, sharding to complex data analytics PostgreSQL really has it all.

Manage your Cloud Infrastructure through Open Source
Public clouds have been continually expanding its fleet of cloud services and is launching products to its large catalog. Their existing services also keep receiving regular updates to add the capabilities they have to offer. Since the past few years, AWS, Google Cloud and Azure have consolidated a lot of management features to operation services, and added more administrative capabilities. More significantly, thanks to a strong user base, there are also pretty useful and effective open source tools built by the community that exist in the wild that have proved to be extremely useful and reliable for daily operations and deployments.
This talk uncovers a suite of cloud provider services in combination with open source tools that allow the infrastructure and platform teams running the cloud to effectively control their regular cloud operations. This includes handling and all the existing computation workloads and CI/CD pipelines and transitioning them to Infrastructure as Code by leveraging these relatively unknown powerful options. The workflows introduced allow for comprehensive monitoring and securing the resources and can be applied wherever the customer are in their cloud journey.

Virtual Reality for All
When Life Gives you Orange, Make Data Speak Volumes!
In this talk we will walk through the concept of Data mining and visualization right from the basics. A free and open source tool for data visualization -Orange from a beginner to an advance level will also be covered. We will also cover the concepts of data mining and data warehousing to gain a deeper insight into the concept and help understand the process form the core level. Data mining refers to an autonomous process of discovery of previously unknown patterns which are valid, potentially useful or novel from large database.Orange is Open source machine learning, data visualization and data mining toolkit.
Orange features an interactive data visualization platform. The platform provides a wide variety of data analysis and visualization by statistical distributions, scatter plots, box plots, decision trees, heat maps, linear projections to name a few. By carefully selecting attributes in the dataset we can drill down multidimensional data to 2D. It helps in fast prototyping of data analysis workflow. The talk will also cover the recent and diverse existing use cases of Orange like: 1. Analysis of hyperspectra images from the Ryugu asteroid 2. Language support for 50 languages 3. bioinformatics, and many more. By the end of the talk attendees would have a clear knowledge of • What Orange is • How they can use it in work or side projects • Be able to use it as a separate tool or embed it as a library in their existing Python projects And use all functionalities of Orange of data mining and visualization to the fullest!

The death of KISS
The world is moving on a super highway of data, and response time needs to be short to cater to the mass market. We, the ones making it work – either in code or operations ,needs to ensure we answer that demand, but does it really have to be so complex ? Why are “simple” solutions frowned upon ? where did it all go wrong?

Reducing the boot time of Linux devices
A pragmatic approach
We all want our devices to boot faster, but how much effort do you want to dedicate to optimizing and maintaining a custom kernel and apps? This presentation offers a graded list of things you can do to reduce boot time. They start with simple changes, such as adjusting the position of your main application in the init sequence.
Then there are the changes you can make to the kernel and bootloader configuration to speed things up, and finally, there are moderately advanced techniques such as using U-Boot in falcon mode. All of this can be done using standard configuration techniques, with the idea of being able to maintain these changes in the future. I will show the effect of each of these changes
on typical a embedded dev board so that you can judge for yourself where on the journey you want to jump off.

I don’t know about the rest of you, but almost every sysadmin I know has at one point written an IRC bot or at least grumbled about the existing ones and thought about it.
These days, in the brave new world of slack and hipchat and mattermost and CLOUD CLOUD CLOUD CLOUD writing bots has been rebranded as ‘chatops’ – and since I was looking at setting up some systems bots, I investigated the current state of the art.
Apparently unified authentication and authorisation isn’t web scale.
So I stopped, stepped back, and asked: in 2019, what do I actually want out of a bot?
- Easy and unified configuration
- Language agnostic for plugins
- That includes being able to write commands as shell scripts
- Authentication and authorisation as a core concept
- Uptime-maximising multi process architecture
- Uniform access to whichever chat system you’re using
So I built something that provides all of those, and in this talk I’ll introduce you to the end result, the architecture, and most importantly, how to go as quickly as possible from zero to a deployment that’s actually useful for day to day sysadmin and operations work.
Hopefully you’ll find the end result involves less grumbling for you too.
