Hadoop isn't limited to running Java code, you can write your jobs in a variety of dynamic languages.
This talk is about Hadoop's Streaming API, and the best way we found to run Perl jobs on Amazon's Elastic MapReduce platform.
Your Hive honeymoon can be cut short if you don't take the necessary precautions. In this talk I'll share my experience with Hive in the last 3 years (in Elastic MapReduce and Cloudera CDH3), describing what I got wrong the first time around, and what eventually saved the day. I've used Hive in environments with a number of events ranging from a few million to a few billion a day, so hopefully there'll be something for everyone.

Software smoke testing is a preliminary level of testing. It makes certain that all of the primary components of a system are functioning correctly. For example, when installing a new secured Hadoop cluster, running a series of quick tests to make sure that things like HDFS and MapReduce are operational can save a lot of headache before enabling Kerberos. Smoke tests can also save you time and embarrassment by making sure that things work before you turn the cluster over to your customer.
In this talk, Michael Arnold will explain the utility of testing Hadoop components after cluster builds and software upgrades. Michael will present code examples that you can use to confirm functionality of Spark, Kudu, HBase, Kafka, MapReduce, etc on your cluster.

Accumulo Summit 2015: Zookeeper, Accumulo, and You [Internals]Accumulo Summit
Talk Abstract
Apache ZooKeeper plays a central role within the Accumulo architecture. Its quorum consistency model supports an overall Accumulo architecture with no single points of failure. Beyond that, Accumulo leverages ZooKeeper to store and communication configuration information for users and tables, as well as operational states of processes and tablets. For most Accumulo users, ZooKeeper is a black box full of goodness. Unfortunately, operational challenges mean we often have to delve into the dark depths to decipher what's going on when something goes wrong. In this talk, we will cover some basics about ZooKeeper's role, what it's good at and what it's not. Then we will discuss ways to debug what's stored inside of ZooKeeper, including how to overcome challenges with ZooKeeper's sometimes difficult ACL model.

This describes a Functional Programming approach to computing AWS Glacier "tree hash" values, hiding the tail-call elimination in Perl5 with a keyword and also shows how to accomplish the same result in Perl6.
This was the talk actually given at YAPC::NA 2016 by Dr. Conway and myself.
Here's a presentation I did for the Japanese Perl Association on April 21st, 2009.
It covers 10 aspects of Catalyst that may not be documented or discussed as much as they could be, that are very useful.
Implementing Glacier's Tree Hash using recursive, functional programming in Perl5. With Keyword::Declare we get clean syntax for tail-call elimination. Result is a simple, fast, functional solution.
Technical operations is plagued with an unhealthy infatuation of typically untested, imperative code with a high reliance on shared mutable state using dynamically typed languages such as Ruby, Python, Bash, and - ugh - remember Perl? :) In an age where building reliable infrastructure to elastically scale applications and services are paramount to business success, we need to start rethinking the infrastructure engineer’s toolkit and guiding principles. This talk will take a look at applying various functional techniques to building and automating infrastructure. From functional package management and congruent configuration to declarative cloud provisioning we’ll see just how practical these techniques typically used in functional programming for applications can be used to help build more robust and predictable infrastructures. While specific code examples will be given, the emphasis of the talk will be on guiding principles and functional design.

5 must have patterns for your microservice - techoramaAli Kheyrollahi
"Netflix is actually a log generating application that just happens to stream movies"
Building a service/Microservice is itself easy. Scaling it on the cloud is not that hard either but operating, maintaining and iterating a production large scale service is not just about linearisation. As Cockcroft points out, telemetry and monitoring is the most important aspect of building Microservices
We discuss 5 patterns that any serious Microservice should have:
- Canary (an endpoint reporting health of underlying dependencies)
- IO monitor (measuring all calls from Microservice to external dependencies)
- A circuit breaker
- An ActivityId-Propagator
- An exception and short timeout retry policy

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
Alt. GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using ...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).

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

2. WESTIE: HISTORY
• West Highland White Terrier is a breed of dog native
to Scotland. It had its origin in the crossings realized
between the cairn terriers. It is said that Scottish
colonel E.D Malcolm mistook his favorite cairn of
champagne color with a rabbit and shot him by
accident. This event made him pay more attention to
the born Caucasus specimens, which were crossed
between them to give rise to the west terriers, which
gave the hunters a better visualization of their
companions of hunts.
