Containers: Anti Pattern
Containers: Anti PatternJeeva Chelladhurai Docker has taken the IT industry by storm, and undeniably it is one of the most popular technologies these days. Docker is being adopted widely because of its simplicity to develop, test and deploy. It is loved by DevOps community as it is inherently designed to build once and deploy in different environment multiple times. The docker containers are ideal deployment units in Microservice Architecture (MSA) because it is very easy to spin new containers and scale them up and down as per the need. Though Docker has such a widespread adoption and it solves many industrial use cases, there are many containerization anti-patterns emerging due to the misunderstanding of containerization. In this talk we will explore: some of the anti-patterns, symptoms to identify those anti-patterns and the solution.

Introduction to Advanced Javascript
Introduction to Advanced JavascriptCollaboration Technologies object-oriented JavaScript is somewhat redundant, as the JavaScript language is completely object-oriented and is impossible to use otherwise.
Objects are the foundation of JavaScript. Virtually everything within the language is an object. Much of the power of the language is derived from this fact.
Design patterns are advanced object-oriented solutions to commonly occurring software problems. Patterns are about reusable designs and interactions of objects.

Introduction to python
Introduction to pythonYi-Fan Chu This document provides an introduction and overview of Python including sections on syntax, lists and dictionaries, for loops, and implementation examples. The introduction covers that Python code is indented using whitespace rather than brackets, semicolons are optional, and data types do not need declaration. Lists are described as arrays that can hold different data types indexed by number, while dictionaries hold key-value pairs indexed by keys that can be numbers, strings, or other data types. For loops in Python iterate over each item in a list or dictionary without needing an explicit condition. The implementation section provides examples of using for loops over lists, creating and accessing a dictionary of fruits, and making lists of dictionaries to demonstrate Python concepts.

Hybridize Functions: A Tool for Automatically Refactoring Imperative Deep Lea...Raffi Khatchadourian Efficiency is essential to support responsiveness w.r.t. ever-growing datasets, especially for Deep Learning (DL) systems. DL frameworks have traditionally embraced deferred execution-style DL code—supporting symbolic, graph-based Deep Neural Network (DNN) computation. While scalable, such development is error-prone, non-intuitive, and difficult to debug. Consequently, more natural, imperative DL frameworks encouraging eager execution have emerged but at the expense of run-time performance. Though hybrid approaches aim for the “best of both worlds,” using them effectively requires subtle considerations to make code amenable to safe, accurate, and efficient graph execution—avoiding performance bottlenecks and semantically inequivalent results. We discuss the engineering aspects of a refactoring tool that automatically determines when it is safe and potentially advantageous to migrate imperative DL code to graph execution and vice-versa.

• The Crime Lab, founded by former cybercrime head Manolis Sfakianakis,
• Panagiotis Pierros, security consultant and expert,
• and Tictac Cyber Security, led by Mike Mingos, providing the technical backbone and operational execution.
The event was honored by the presence of Greece’s Minister of Development, Mr. Takis Theodorikakos, signaling the importance of cybersecurity in national maritime competitiveness.
🎯 Key topics covered in the talk:
• Why cyberattacks are now the #1 non-physical threat to maritime operations
• How ransomware and downtime are costing the shipping industry millions
• The 3 essential pillars of maritime protection: Backup, Monitoring (EDR), and Compliance
• The role of managed services in ensuring 24/7 vigilance and recovery
• A real-world promise: “With us, the worst that can happen… is a one-hour delay”
Using a storytelling style inspired by Steve Jobs, the presentation avoids technical jargon and instead focuses on risk, continuity, and the peace of mind every shipping company deserves.
🌊 Whether you’re a shipowner, CIO, fleet operator, or maritime stakeholder, this talk will leave you with:
• A clear understanding of the stakes
• A simple roadmap to protect your fleet
• And a partner who understands your business

GDG Cloud Southlake #42: Suresh Mathew: Autonomous Resource Optimization: How...James Anderson Autonomous Resource Optimization: How AI is Solving the Overprovisioning Problem
In this session, Suresh Mathew will explore how autonomous AI is revolutionizing cloud resource management for DevOps, SRE, and Platform Engineering teams.
Traditional cloud infrastructure typically suffers from significant overprovisioning—a "better safe than sorry" approach that leads to wasted resources and inflated costs. This presentation will demonstrate how AI-powered autonomous systems are eliminating this problem through continuous, real-time optimization.
Key topics include:
Why manual and rule-based optimization approaches fall short in dynamic cloud environments
How machine learning predicts workload patterns to right-size resources before they're needed
Real-world implementation strategies that don't compromise reliability or performance
Featured case study: Learn how Palo Alto Networks implemented autonomous resource optimization to save $3.5M in cloud costs while maintaining strict performance SLAs across their global security infrastructure.
Bio:
Suresh Mathew is the CEO and Founder of Sedai, an autonomous cloud management platform. Previously, as Sr. MTS Architect at PayPal, he built an AI/ML platform that autonomously resolved performance and availability issues—executing over 2 million remediations annually and becoming the only system trusted to operate independently during peak holiday traffic.

Challenges in Migrating Imperative Deep Learning Programs to Graph Execution:...Raffi Khatchadourian Efficiency is essential to support responsiveness w.r.t. ever-growing datasets, especially for Deep Learning (DL) systems. DL frameworks have traditionally embraced deferred execution-style DL code that supports symbolic, graph-based Deep Neural Network (DNN) computation. While scalable, such development tends to produce DL code that is error-prone, non-intuitive, and difficult to debug. Consequently, more natural, less error-prone imperative DL frameworks encouraging eager execution have emerged at the expense of run-time performance. While hybrid approaches aim for the "best of both worlds," the challenges in applying them in the real world are largely unknown. We conduct a data-driven analysis of challenges---and resultant bugs---involved in writing reliable yet performant imperative DL code by studying 250 open-source projects, consisting of 19.7 MLOC, along with 470 and 446 manually examined code patches and bug reports, respectively. The results indicate that hybridization: (i) is prone to API misuse, (ii) can result in performance degradation---the opposite of its intention, and (iii) has limited application due to execution mode incompatibility. We put forth several recommendations, best practices, and anti-patterns for effectively hybridizing imperative DL code, potentially benefiting DL practitioners, API designers, tool developers, and educators.
