Techniques to Improve Cache Speed
Techniques to Improve Cache SpeedZohaib Hassan One of challenges we face at DoorDash everyday is to keep our API latency low. While the problem sounds simple on the surface, it gets interesting some times. One of our endpoints that serves restaurant menus to our consumers had high p99 latency numbers. Since it’s a high traffic endpoint we naturally use cache pretty intensively. We cache our serialized menus in Redis to avoid repeated calls to DB, and spread out the read traffic load. By the end of this post we will present you how we used compression to not only improve our latency, but also got ourselves more space to cache.

Containers > VMs
Containers > VMsDavid Timothy Strauss Historically, sharing a Linux server entailed all kinds of untenable compromises. In addition to the security concerns, there was simply no good way to keep one application from hogging resources and messing with the others. The classic “noisy neighbor” problem made shared systems the bargain-basement slums of the Internet, suitable only for small or throwaway projects.
Serious use-cases traditionally demanded dedicated systems. Over the past decade virtualization (in conjunction with Moore’s law) has democratized the availability of what amount to dedicated systems, and the result is hundreds of thousands of websites and applications deployed into VPS or cloud instances. It’s a step in the right direction, but still has glaring flaws.
Most of these websites are just piles of code sitting on a server somewhere. How did that code got there? How can it can be scaled? Secured? Maintained? It’s anybody’s guess. There simply isn’t enough SysAdmin talent in the world to meet the demands of managing all these apps with anything close to best practices without a better model.
Containers are a whole new ballgame. Unlike VMs, you skip the overhead of running an entire OS for every application environment. There’s also no need to provision a whole new machine to have a place to deploy, meaning you can spin up or scale your application with orders of magnitude more speed and accuracy.

Le PHP est devenu une véritable langue de programmation, avec une style similaire du C et du C++, le PHP est très puissante pour les applications sur Internet.
PHP est le langage de référence pour le développement d'applications web, de même qu'Apache équipe la grande majorité des serveurs HTTP et que MySQL est la plus utilisée des bases de données SQL Open Source. C'est ainsi que la plate-forme appelée LAMP s'est imposée comme l'architecture la plus courante pour publier sur le web.
Pour qui possède (ou loue) un ordinateur avec Ubuntu, Debian, OS X, ou tout autre distribution dérivée d'Unix, l'effort technique pour créer son propre serveur web et le lier avec un nom de domaine est très abordable (au moins au début). Il est ainsi possible de s'écarter des hébergements uniformes. Pour cela, vous verrez tout au long de cette formation PHP MySQL quels sont les outils système (peu nombreux) que vous devez connaître pour installer Apache et les autres composants.
Vous aborderez pendant cette formation PHP MySQL pas à pas toutes les bases algorithmiques de PHP, les types de données, les fonctions, les structures de contrôle, ainsi que les spécificités liées au web : le traitement des formulaires, la gestion des cookies, des sessions, etc.
Vous apprendrez avec cette formation PHP MySQL les premiers jalons des bonnes pratiques de la programmation, en évoquant les outils de tests automatiques (développés plus tard), la documentation du code, ou l'esquisse d'une organisation du code, comprendre les bases de données relationnelles et la notion de modèle. Vous vous servirez de l'algèbre relationnelle pour fouiller dans les données et vous mettrez en œuvre les opérations fondamentales résumées sous l'acronyme CRUD : Create, Read, Update, Delete.
Au fil de cette formation PHP MySQL, nous commencerons à réfléchir à une application-jouet qui sera un mini-Trello, à savoir une application en ligne permettant de gérer des listes de tâches, qui pourrait être tout aussi bien un outil pour prendre des décisions.
A l’issue de cette formation PHP MySQL, vous aurez tous les outils pour héberger et développer vous -mêmes vos applications en PHP et partir vers d'autres horizons.

Architecting cloudTahsin Hasan The document discusses various stages in architecting an application for the cloud as it grows in scale and complexity.
Stage 1 involves a simple architecture suitable for startups with low overhead. Stage 2 adds redundancy as the business grows. Stage 3 requires the addition of load balancers and more servers as publicity increases load. Stage 4 requires database replication and partitioning as single databases can no longer handle the load. Later stages involve rearchitecting the application and databases to support further scaling through techniques like data partitioning, database clustering, and optimizing code and resources.

MySQL 101 PHPTek 2017
MySQL 101 PHPTek 2017Dave Stokes MySQL replication allows data from a master database server to be copied to one or more slave database servers. It provides advantages like improving performance through load balancing, increasing data security with backups on slaves, and enabling analytics on slaves without impacting the master. Basic replication involves setting up a master server and slave server with unique IDs, configuring the master to log binary changes, and pointing the slave to the master so it can copy the binary log entries.

RDS for MySQL, No BS Operations and Patterns
RDS for MySQL, No BS Operations and PatternsLaine Campbell RDS for MySQL provides a fully managed MySQL database in the cloud. It handles backups, provisioning, patching, and failover automatically. While convenient, RDS has some limitations like inability to choose database versions, limited control over maintenance windows, and downtime required for migrations or upgrades. Careful planning is needed for workloads with high availability or latency requirements. Overall RDS reduces DBA overhead but still requires expertise for design, tuning, and automation.
More on gdb for my sql db as (fosdem 2016)
More on gdb for my sql db as (fosdem 2016)Valeriy Kravchuk Gdb can be used by MySQL DBAs as a last resort tool to troubleshoot issues. It allows inspecting variable values, setting variables, calling functions, and getting stack traces from a running or crashed mysqld process. The presentation provides examples of using gdb to study InnoDB locks, metadata locks, and real bugs. While gdb can help in some cases, ideally DBAs should use profiling tools, implement missing features, and follow best practices to avoid needing gdb.

Caching and tuning fun for high scalability
Caching and tuning fun for high scalabilityWim Godden Caching has been a 'hot' topic for a few years. But caching takes more than merely taking data and putting it in a cache : the right caching techniques can improve performance and reduce load significantly. But we'll also look at some major pitfalls, showing that caching the wrong way can bring down your site. If you're looking for a clear explanation about various caching techniques and tools like Memcached, Nginx and Varnish, as well as ways to deploy them in an efficient way, this talk is for you.
Itb session v_memcached
Itb session v_memcachedSkills Matter The document discusses running memcached clusters on Amazon EC2. It covers key concepts like caching, clusters, and infrastructure as a service (AWS). It then provides step-by-step instructions for setting up a memcached cluster on EC2, including creating security groups, launching EC2 instances from AMIs, and configuring the memcached servers and clients. The summary concludes that setting up and running memcached clusters on infrastructure as a service environments like EC2 is straightforward.
Testing Persistent Storage Performance in Kubernetes with Sherlock

MariaDB, MySQL and Ansible: automating database infrastructures
MariaDB, MySQL and Ansible: automating database infrastructuresFederico Razzoli This document summarizes a talk on automating database infrastructures using MariaDB, MySQL and Ansible. It discusses Ansible concepts like inventories, modules, playbooks, roles, plays, variables and facts. It provides code examples of using Ansible to automate the deployment and configuration of MariaDB and MySQL database servers through plays, roles, variables and templates. It also discusses best practices for making tasks idempotent, using conditional tasks, tags and validating variables.
Node.js - Advanced Basics
Node.js - Advanced BasicsDoug Jones Node has revolutionized modern runtimes. Their async by default strategy boasts 3x the throughput of Java. And yet, the language runs 5x slower than C++ (when JS is interpreted).
This talk is an advanced intro into the world of Node where we take a closer look under the hood. What's the event loop? Why are there multiple compilers for JS in Node/V8? How many threads are actually used in Node and for what purpose? We'll answer these questions and more as we go over libuv, v8, the node core library, npm, and more.
If you're developing with Node, want to start, or are just curious about how it works, please check it out!
MySQL database replication
MySQL database replicationPoguttuezhiniVP This document describes how to configure MySQL database replication between a master and slave server. The key steps are:
1. Configure the master server by editing its configuration file to enable binary logging and set the server ID. Create a replication user and grant privileges.
2. Export the databases from the master using mysqldump.
3. Configure the slave server by editing its configuration file to point to the master server. Import the database dump. Start replication on the slave.
4. Verify replication is working by inserting data on the master and checking it is replicated to the slave.
Mysql high availability and scalability
Mysql high availability and scalabilityyin gong The document discusses high availability and scalability in MySQL. It describes various techniques for achieving high availability including replication, clustering, and shared storage solutions. It also discusses different approaches for scaling MySQL including replication, sharding, and clustering. MySQL replication is described as asynchronous with a single master and multiple read-only slaves. MySQL Cluster provides synchronous replication across nodes and automatic failover for high availability.
Introduction to Galera Cluster
Introduction to Galera ClusterCodership Oy - Creators of Galera Cluster - Galera is a MySQL clustering solution that provides true multi-master replication with synchronous replication and no single point of failure.
- It allows high availability, data integrity, and elastic scaling of databases across multiple nodes.
- Companies like Percona and MariaDB have integrated Galera to provide highly available database clusters.
Speed up R with parallel programming in the Cloud
Speed up R with parallel programming in the CloudRevolution Analytics There are many common workloads in R that are "embarrassingly parallel": group-by analyses, simulations, and cross-validation of models are just a few examples. In this talk I'll describe several techniques available in R to speed up workloads like these, by running multiple iterations simultaneously, in parallel.
Many of these techniques require the use of a cluster of machines running R, and I'll provide examples of using cloud-based services to provision clusters for parallel computations. In particular, I will describe how you can use the SparklyR package to distribute data manipulations using the dplyr syntax, on a cluster of servers provisioned in the Azure cloud.

aws basics
aws basicsSean Hull The document discusses the evolution of data centers from the 1990s to today and the rise of cloud computing. It describes infrastructure as a service (IaaS) which provides raw computing power on demand from the cloud. Some benefits of the cloud include on-demand scaling, lower upfront costs, easier disaster recovery, and automated deployments. However, challenges include potential performance issues due to shared resources and security considerations. The cloud is well-suited for applications with seasonal traffic patterns, short-term needs, or augmenting existing infrastructure. The summary concludes that adopting a hybrid cloud approach or using the cloud's auto-scaling abilities could save costs depending on factors like existing infrastructure investments and disaster recovery spending.

DevOpsDays Atlanta 2025 - Building 10x Development Organizations.pptxJustin Reock Building 10x Organizations with Modern Productivity Metrics
10x developers may be a myth, but 10x organizations are very real, as proven by the influential study performed in the 1980s, ‘The Coding War Games.’
Right now, here in early 2025, we seem to be experiencing YAPP (Yet Another Productivity Philosophy), and that philosophy is converging on developer experience. It seems that with every new method we invent for the delivery of products, whether physical or virtual, we reinvent productivity philosophies to go alongside them.
But which of these approaches actually work? DORA? SPACE? DevEx? What should we invest in and create urgency behind today, so that we don’t find ourselves having the same discussion again in a decade?

How analogue intelligence complements AI
How analogue intelligence complements AIPaul Rowe
Artificial Intelligence is providing benefits in many areas of work within the heritage sector, from image analysis, to ideas generation, and new research tools. However, it is more critical than ever for people, with analogue intelligence, to ensure the integrity and ethical use of AI. Including real people can improve the use of AI by identifying potential biases, cross-checking results, refining workflows, and providing contextual relevance to AI-driven results.
News about the impact of AI often paints a rosy picture. In practice, there are many potential pitfalls. This presentation discusses these issues and looks at the role of analogue intelligence and analogue interfaces in providing the best results to our audiences. How do we deal with factually incorrect results? How do we get content generated that better reflects the diversity of our communities? What roles are there for physical, in-person experiences in the digital world?

Is AI just another technology, or does it fundamentally change the way we live and think?
Every technology has a direct impact with micro-ethical consequences, some good, some bad. However more profound are the ways in which some technologies reshape the very fabric of society with macro-ethical impacts. The invention of the stirrup revolutionised mounted combat, but as a side effect gave rise to the feudal system, which still shapes politics today. The internal combustion engine offers personal freedom and creates pollution, but has also transformed the nature of urban planning and international trade. When we look at AI the micro-ethical issues, such as bias, are most obvious, but the macro-ethical challenges may be greater.
At a micro-ethical level AI has the potential to deepen social, ethnic and gender bias, issues I have warned about since the early 1990s! It is also being used increasingly on the battlefield. However, it also offers amazing opportunities in health and educations, as the recent Nobel prizes for the developers of AlphaFold illustrate. More radically, the need to encode ethics acts as a mirror to surface essential ethical problems and conflicts.
At the macro-ethical level, by the early 2000s digital technology had already begun to undermine sovereignty (e.g. gambling), market economics (through network effects and emergent monopolies), and the very meaning of money. Modern AI is the child of big data, big computation and ultimately big business, intensifying the inherent tendency of digital technology to concentrate power. AI is already unravelling the fundamentals of the social, political and economic world around us, but this is a world that needs radical reimagining to overcome the global environmental and human challenges that confront us. Our challenge is whether to let the threads fall as they may, or to use them to weave a better future.
