The pragmatic programmer

Nilesh Sharma

A pragmatic programmer is someone who deals with problems sensibly and realistically based on practical considerations rather than theory. They are typically early adopters of new technologies, inquisitive critical thinkers who don't accept things at face value. Pragmatic programmers understand the underlying nature of problems, are familiar with a broad range of technologies, and care about crafting high quality software. Some tips for becoming pragmatic include fixing issues as soon as they arise rather than living with "broken windows," being an agent of positive change, and remembering the big picture rather than getting lost in details.

The pragmatic programmer

Joel Corrêa

The document discusses the characteristics of a pragmatic programmer, which include being an easy adapter, inquisitive critical thinker, realistic, and familiar with various technologies. It emphasizes communication, taking responsibility, avoiding broken windows, estimating to avoid surprises, refactoring when needed, and thorough testing. The pragmatic approach involves unambiguous representations, reversibility, programming close to the problem domain, and following the Law of Demeter.

Hyper-V Disaster Recovery Optimizing

Ahmad Firdaus

This document discusses four methods for Hyper-V disaster recovery: 1. Export/Import - Basic backup/restore but VMs must be shut down during export and individual file restoration is not possible. 2. Snapshots - Allow restoring to prior configurations but have performance and data integrity risks. Snapshots cannot be easily moved. 3. Replication - Provides workload resilience by replicating VMs between sites, but requires administrator monitoring and at least two Hyper-V hosts. 4. Commercial software - Easy to use with fast, flexible backup/restore, but is more expensive than other options.

Agile Austin - Peer Code Review An Agile Process

Peer Code Review An Agile Process

gsporar

Peer code review is one of the most effective ways to find defects – but is it agile? Because agile teams loathe heavy process, code review practices can easily fail. However, lightweight peer code review aligns well with the central tenets of agile—keeping feedback close to the point of creation, increasing team velocity by finding defects faster, and improving collective code ownership through frequent collaboration. Gregg Sporar shares recent research on code review practices and describes an agile code review approach—how much time to spend, which code to review, how much code to review at a time, how to set goals, the value of annotation, and more. After comparing four styles of code review—pair programming, over-the-shoulder, email, and tool-assisted—Gregg gives specific advice for creating review checklists and dealing with the social effects of code review in an agile environment.

An Actionable Framework for Understanding and Improving Developer Experience

Margaret-Anne Storey

Authors: Michaela Greiler, Margaret-Anne Storey, Abi Noda Abstract: Developer experience is an important concern for software organizations as enhancing developer experience improves productivity, satisfaction, engagement and retention. We set out to understand what affects developer experience through semi-structured interviews with 21 developers from industry, which we transcribed and iteratively coded. Our findings elucidate factors that affect developer experience and characteristics that influence their respective importance to individual developers. We also identify strategies employed by individuals and teams to improve developer experience and the barriers that stand in their way. Lastly, we describe the coping mechanisms of developers when developer experience cannot be sufficiently improved. Our findings result in the DX Framework, an actionable conceptual framework for understanding and improving developer experience. The DX Framework provides a go-to reference for organizations that want to enable more productive and effective work environments for their developers.

Agile Australia 2016 - Rescuing Legacy Software from Impending Doom

Jacques De Vos

Dealing with an ageing code base is one of the hardest challenges that software development teams face. Legacy code bases can slow teams to a crawl, and therefore it is critical to solve this on the road to agility. Software rewrites fail at alarming rates! Refactoring – a safer approach – has emerged as the de-facto technique to tackle this challenge. This session we will equip attendees with techniques and lessons to help them refactor more effectively. We will share our experience gained while working with various software teams, from startups to mid-sized organisations, that attempted to rescue their legacy from impending doom. You will learn how to justify the investment in refactoring legacy code to product owners; when and how to apply different refactoring workflows on legacy code; and practical tips to avoid common pitfalls when refactoring code.

Odoo ERP Vs. Traditional ERP Systems – A Comparative Analysis

Envertis Software Solutions

When it is all about ERP solutions, companies typically meet their needs with common ERP solutions like SAP, Oracle, and Microsoft Dynamics. These big players have demonstrated that ERP systems can be either simple or highly comprehensive. This remains true today, but there are new factors to consider, including a promising new contender in the market that’s Odoo. This blog compares Odoo ERP with traditional ERP systems and explains why many companies now see Odoo ERP as the best choice. What are ERP Systems? An ERP, or Enterprise Resource Planning, system provides your company with valuable information to help you make better decisions and boost your ROI. You should choose an ERP system based on your company’s specific needs. For instance, if you run a manufacturing or retail business, you will need an ERP system that efficiently manages inventory. A consulting firm, on the other hand, would benefit from an ERP system that enhances daily operations. Similarly, eCommerce stores would select an ERP system tailored to their needs. Because different businesses have different requirements, ERP system functionalities can vary. Among the various ERP systems available, Odoo ERP is considered one of the best in the ERp market with more than 12 million global users today. Odoo is an open-source ERP system initially designed for small to medium-sized businesses but now suitable for a wide range of companies. Odoo offers a scalable and configurable point-of-sale management solution and allows you to create customised modules for specific industries. Odoo is gaining more popularity because it is built in a way that allows easy customisation, has a user-friendly interface, and is affordable. Here, you will cover the main differences and get to know why Odoo is gaining attention despite the many other ERP systems available in the market.

Symfony apps are not an exception. In this talk, I will take you for a spin around the performance racetrack. We’ll explore common pitfalls - those hidden potholes on your application that can cause unexpected slowdowns. Learn how to spot these performance bumps early, and more importantly, how to navigate around them to keep your application running at top speed. We will focus in particular on tuning your engine at the application level, making the right adjustments to ensure that your system responds like a well-oiled, high-performance race car.

Hand Rolled Applicative User ValidationCode Kata

Philip Schwarz

Could you use a simple piece of Scala validation code (granted, a very simplistic one too!) that you can rewrite, now and again, to refresh your basic understanding of Applicative operators <*>, <*, *>? The goal is not to write perfect code showcasing validation, but rather, to provide a small, rough-and ready exercise to reinforce your muscle-memory. Despite its grandiose-sounding title, this deck consists of just three slides showing the Scala 3 code to be rewritten whenever the details of the operators begin to fade away. The code is my rough and ready translation of a Haskell user-validation program found in a book called Finding Success (and Failure) in Haskell - Fall in love with applicative functors.

A Study of Variable-Role-based Feature Enrichment in Neural Models of Code

Aftab Hussain

Understanding variable roles in code has been found to be helpful by students in learning programming -- could variable roles help deep neural models in performing coding tasks? We do an exploratory study. - These are slides of the talk given at InteNSE'23: The 1st International Workshop on Interpretability and Robustness in Neural Software Engineering, co-located with the 45th International Conference on Software Engineering, ICSE 2023, Melbourne Australia
