This document is a blog post by Jose Morales about being called an "old guy" by his son. He notes that while it may seem like an insult, he takes it as a term of respect since he also calls his own father "Viejo." He then lists several accomplishments over his career in education, music production, and now pursuing a degree to show his sons the importance of finishing what you start. Overall, the post frames being older as providing experience, wisdom, and value to offer others.

Idiots guide to jquery

Mark Casias

This document is an introduction to jQuery that discusses what jQuery is, why it is useful with features like small file size and large community, how to select and manipulate page elements, handle events, make AJAX requests, use jQuery UI for interfaces, and find additional resources. The document also briefly mentions other JavaScript libraries and recommends jQuery plugins for extending functionality.

Please Don't Touch the Slow Parts

Federico Galassi

Talk i gave at Better Software on May 5th 2010, together with Fullo of Ideato. It's about improving web applications speed. Based on Steve Souders work. I'll be giving a newer version of the talk at PHP Day 2010 Also http://www.ideato.it/ http://federico.galassi.net/ http://www.stevesouders.com/ http://www.bettersoftware.it/ http://www.phpday.it/ Follow me on Twitter https://twitter.com/federicogalassi

Object XML Mappings

guest140888

The document discusses object-relational mapping (ORM) and introduces object-XML mapping as an alternative. It proposes representing XML documents as objects with classes that map to XML elements. This would allow applying ORM techniques to store and query XML documents using an XML database with XPath support. The author proposes researching how to extend Ruby on Rails with an XPath accelerator to create an efficient XML database and implement XML-based object mapping on it to enable mapping between XML documents and application objects.

Data Driven Monitoring

Daniel Schauenberg

At Etsy we are big fans of graphing and monitoring all the things. We deploy our main site several times a day and our monitoring provides us with the tight feedback loop we need to make this possible. The same goes for changes in the infrastructure which are deployed in a similar fashion of small and frequent changes. For this to work we have build up monitoring that tracks changes and possible problems in every nook and cranny of the Etsy stack, be it a network change, systems or application level performance or how bad the last week of on-call rotation was. The flipside of monitoring all the things however is that we have a myriad of graphs and alerts that can potentially be important and page the on-call engineer at any given time. The risk of running into alert fatigue and a normalization of deviance through not properly scoped checks is rising with this ever increasing size of the monitoring system. This is why we also continuously monitor our monitoring system and ask questions about whether we have all the information at hand when we get paged, if certain alerts actually need to wake someone up or if they are needed at all. I will give a quick overview of how our monitoring stack is built and then give insights into how we gather data about it and use it to make things better. For site operations and more importantly for the human getting paged when something does go wrong.

Development is Production Too

jgoulah

The document discusses differences between development and production environments and challenges related to managing environments and data across stages. It emphasizes the importance of optimizing for consistency across environments and changability. Tools and automation are recommended to help manage shared configurations, virtual machine templates, and subsets of production data in development without compromising the live system.

Ipv6 basics

Relational Database Design

Archit Saxena

The document provides an overview of databases and database design. It defines what a database is, what databases do, and the components of database systems and applications. It discusses the database design process, including identifying fields, tables, keys, and relationships between tables. The document also covers database modeling techniques, normalization to eliminate redundant or inefficient data storage, and functional dependencies as constraints on attribute values.

Building a backend for a successful social game is always challenging: It needs to service over 1 million users per day that generate 10.000 http requests per second or more whereas the vast majority of those requests are changing persistent state. Using a conventional technology stack that leads to over 50,000 database writes per second. Throughout the last two years half a dozen teams at Wooga have set out to build a backends for social games, each trying to improve on previous solutions. Each team was able to leverage experiences made by other teams but was free to choose their own technology stack and hosting environment. They also operated the game themselves in a DevOps way. This talk will trace back that evolution of backends: Starting out with a simple LAMP stack, first replacing PHP by Ruby, then replacing relational by NoSQL databases and ending up in maintaining stateful application servers utilizing Erlang OTP - and more. We will discuss limitations and problems we faced in live operation and show how later teams improved on the overall design.

New models for cultural journalism

Paul Bradshaw

This document discusses new models for cultural journalism in the digital age. It explores how the transition from physical to digital and networked media impacts news production. Key points addressed include how stories become more engaging when they are happening in real-time and supplemented with ongoing context and conversation. The production line is being replaced by networks, where value comes from participant contributions and data. Decentralization of content production is suggested as a new model for journalism.

Como escalar aplicações PHP

Augusto Pascutti

The document discusses ways to scale PHP applications. It covers using indexes, vertical partitioning, replication, load balancing, and storing sessions in a database table to allow sharing session data across multiple servers. Vertical partitioning involves splitting tables across multiple database servers based on certain columns like ID ranges, lists of values, or hashing on columns. Load balancing can be done at the web server level using modules like mod_proxy and mod_rewrite to route requests to read or write servers. Storing sessions in a database table allows session data to be shared between servers.

Usability: Test Types & Ethics

Krista Kennedy

The document discusses different types of usability testing, including exploratory/formative testing which aims to understand why users have difficulties, and assessment/summative testing which evaluates how well a system performs. It also covers iterative design, validation/verification testing, and comparisons between systems. Usability testing should use representative samples of end users, observe them in actual work environments, and include interviews and measurements of performance. The goal is to recommend improvements and ensure ethical treatment of human subjects.

Help Me Design A Better Homepage

jtcchan

John Chan is redesigning the library homepage because the current one is confusing. He wants to highlight the benefits of the library's services to students, such as help from reference librarians with research papers, access to subject librarians in specific fields, access to books from other universities, free group study rooms, equipment like laptops available to borrow, access to professional design software, workshops on research skills, and online access to research materials from off campus. John thanks the student for their feedback on how to communicate these benefits in the new homepage design.

Hoosier Hospitality

Robbin Phillips

The document discusses how to ignite powerful and sustainable word-of-mouth movements. It explains that movements empower people to unite around a common cause or passion and become a self-perpetuating force for growth. Movements are driven by fans who spread the word out of love and passion, whereas campaigns use tactics to target customers and gain market share. Successful movements have shared ownership where people feel empowered to tell the story online and offline, powerful identities, inspirational leaders, and knowledge to empower grassroots evangelists.

Games for the Masses - Wie DevOps die Entwicklung von Architektur verändert (...

Wooga

(Slides in English) Ein Backend für ein weltweit erfolgreiches Social Game zu entwickeln ist nicht einfach, aber die eigentliche Herausforderung ist der Betrieb der Systeme! Bei Wooga sind dieselben zwei bis drei Entwickler für beides verantwortlich. Über die letzten zwei Jahren hat sich ein halbes Dutzend Teams dieser Herausforderung gestellt. Dabei konnten sie auf die Erfahrungen der vorhergehenden Teams zurückgreifen und hatten die Freiheit, eigene Lösungsansätze zu verfolgen. Der Vortrag wird die entstandene Evolution der Backends nachvollziehen: Anfangs LAMP, dann Ruby statt PHP, dann NoSQL statt MySQL und am Ende ohne Datenbank auf Basis von Erlang OTP. Die Darstellung dieser Reise wird anschaulich zeigen, welche Vorteile es haben kann, Entwicklern auch einmal freie Hand zu lassen.

Video for good? Good For Video AIM 2012

Craig Moore

This document discusses viral video strategies and successes. It notes that the Kony 2012 video received over 100 million views in its first few days due to an emotionally compelling story, established fanbase, ease of sharing, and social media influencers promoting it. However, it faced challenges like appearing like "slacktivism" and lack of real-world engagement. Other successful videos like Old Spice commercials are cited. The key takeaways are to know your audience, plan for uncertainties, and connect, converse and create engaging content.

Michael mahlberg exploratory-testing-the_missing_half_of_bdd

Michael Mahlberg

"We should just call it testing - when it's not exploratory testing it's not real testing anyway" -Twitter, Summer 2011 Lately many professional testers have started to make a clear distinctions between thing that we call testing (like TDD and BDD) and what they consider testing - referring to TDD and BDD mostly as checking. And actually I – and I would think many of you as well – have seen projects with a test coverage of 80% and more that still fail to meet the clients' needs. Even though they meet the specifications perfectly. This points to some value that could be added to techniques like BDD and TDD by embracing the ideas from people like James Marcus Bach, Paul Carvalho and Michael Bolton. After giving an overview of current trends in the testing community like ET (exploratory testing) and ATDD (Acceptance Test Driven Development) this session will try to do exactly that: discuss the - often missing - intersection between BDD and exploratory testing and suggest ways to fill it.

Architecting for failure

Michael Brunton-Spall

Given at QCon London 2012 Your systems are going to fail, it might not be today, it might not be tomorrow, but sometime soon, probably at 2am, your systems are going to fail in new and exciting ways. We've shared at QCon before about the core architecture of guardian.co.uk, and how we built the site. Now we are going to tell you what we've learnt since we built it, in what ways it went wrong, and how we are learning to architect for failure at the very beginning of each project.

Summer of tech 2011

John Clegg

The document summarizes a presentation about the Summer of Tech (SoT) internship program. It discusses how SoT helps students get internships in programming, engineering, design, and business analysis. It provides career advice, noting that the job market is tough after the 2011 earthquake in New Zealand. Employers are seeking candidates with experience, strong soft skills like personality and team fit, and a track record of successful projects.

EED - The Container Port PERFORMANCE INDEX 2023

El Estrecho Digital

El Puerto de Algeciras continúa un año más como el más eficiente del continente europeo y vuelve a situarse en el “top ten” mundial, según el informe The Container Port Performance Index 2023 (CPPI), elaborado por el Banco Mundial y la consultora S&P Global. El informe CPPI utiliza dos enfoques metodológicos diferentes para calcular la clasificación del índice: uno administrativo o técnico y otro estadístico, basado en análisis factorial (FA). Según los autores, esta dualidad pretende asegurar una clasificación que refleje con precisión el rendimiento real del puerto, a la vez que sea estadísticamente sólida. En esta edición del informe CPPI 2023, se han empleado los mismos enfoques metodológicos y se ha aplicado un método de agregación de clasificaciones para combinar los resultados de ambos enfoques y obtener una clasificación agregada.
