This document discusses refactoring to functional programming with Scala and Scalaz. It provides examples of filtering data by name and previous executions, handling monad stacks with Task and Future, running actions concurrently with IO and Reader, and reporting results to the console and HTML using streams. It also covers issues with composing reporting and recommends using folds for opaque dependent types.
Python is the choice llanguage for data analysis,
The aim of this slide is to provide a comprehensive learning path to people new to python for data analysis. This path provides a comprehensive overview of the steps you need to learn to use Python for data analysis.
This is talk is about what remains after more than one year of learning about Functional Programming, Category Theory, Lambda Calculus, Javaslang and some Haskell and Scala too.
I work with Apache Spark in Java8 & Javaslang. It’s a distributed computation context that works with large quantities of data.
I started my journey into Functional Programming to reduce the complexity of my code.

Wondering how to model things in Erlang, and what the Actor model is all about? This talk will cover the best of Erlang OTP, delve into using gen_server to model systems in Erlang, and demonstrate the use of supervisor trees to ensure your application stays alive and well. Those new to Erlang might want to look over an intro first, but should still gleam some insights from this talk either way.
Speaker Bio:
Ken Pratt has been working with Erlang full time since the beginning of 2009, which makes him slightly less of an Erlang noob than he was previously. Ken holds a B.Sc. in Computer Science from UBC, and is currently hard at work developing a social networking game at Pug Pharm Productions.
Concurrent programming is one of the major challenges for the software industry. We are in a time of massive experimentation as language designers and programmers search for ways to make concurrent programming easier, less error prone, and more reliable.
This talk will be a survey of concurrent programming constructs which are currently available in some programming language or library. We will look at programming model being presented, as well as examining some of the implementation challenges for the various models.
Flink Forward San Francisco 2019: Build a Table-centric Apache Flink Ecosyste...Flink Forward
Flink Table API was initially created to address the relational query use case. It has been a good addition to DataStream and DataSet API for users to write declarative queries. Moreover, Table API provides a unified API for batch and stream processing. We have been exploring extending the capability of Flink Table API to go beyond the classical relational query. With these work, we are establishing an ecosystem on top of the Table API. This talk will introduce the following enhancements we have made on Table API to expand its horizon. Most of the work has been or will be contributed back to Apache Flink. We will also share our experience of building an ecosystem around Flink Table API, and our vision for Table API in the future.
Non-relational processing API
Relational query is natively supported by Table API. It is also very powerful to express complicated computation logic. However, non-relational API become handy to perform a general purpose computation. We have introduced a set of non-relational methods, such as map() and flatMap(), to Table API in a systematic manner to improve the user experience in general.
Interactive programming
Ad-hoc queries is a pretty common use case for processing engines, especially for batch processing. In order to meet the requirements for such use cases, we introduced interactive programming to Table API, which allows users to cache the intermediate result. We envision the underlying service, which caches the intermediate Flink Table, will grow significantly to provide more sophisticated capabilities.
Iterative processing
Compared with DataSet and DataStream, one thing missing from Table is native iteration support. Instead of naively copying the native iteration API from DataSet / DataStream, we designed a new API to address the caveats that we have seen in the existing iteration support in DataStream and DataSet.
ML on Table API
One important part of the Flink ecosystem is ML. We have proposed to build a ML on top of Table API, so that the algorithm engineers can also benefit from the optimizations provided by Flink, in both batch and stream jobs.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

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).

Html output: I suck at html / javascript
Open Source = find people! Clinton -> new design, new CSS
But implementation: ugh…
Simplification / Composition / extension
What about being “pure”
Lots of possibilities
More knowledge
What happened: Success or Failure?
This is eventually looking good and possibly looking fantastic
Simple structure:
But complex execution model -> even not enough separation between declaration and run
And several functionalities on top
- by tag -> read command line
- by previous -> read files
Execution:
- must respect steps!
- must be fully concurrent
Reporting:
- console must flow!
- statistics must be stored
Memory?
Thread pool?
Interested by the Cake Pattern and the ability to “hide” the implementation + Daniel Spiewak presentation on parametrizing it with a Monad
But how far can you go with small functions?
Use an elaborate data structure right away
Process[Task, T] is a stream of Ts produced by a Task
Process1 is like a map or filter operation
A Task is an Error/Future monad stack
Use a for comprehension
Can be a bit tedious to retrofit the code like that
But this is mostly a mechanical transformation
And this provides a benefit
Liberally use the configuration to influence the behaviour of your programming
That’s dependency injection!
Better than I feared
In Scala you need to build a special stack for what you are doing, Reader Writer State won’t work easily
Build your own collection of operators to create values, fromIO, failure,…
Question : can you keep Configuration modular?
Question: how to operate with another stack like Action <-> Task
Use an elaborate data structure right away
Not composable because the fragments are going to be executed twice
Use a Fold to accumulate state
Stacks not too hard to use
Streamz a very powerful model, but very recent library and might need to come up with Folds for additional composition
Being Functional = Honest brings opportunities
- inject anything anywhere
- careful execution model + flatmap == better execution control
