Gerenciamento de Memória não é um problema resolvido. Estamos constantemente evoluindo formas de trabalhar memória em diferentes cenários. Garbage Collectors não são mágicos, são um conjunto de trade-offs entre performance e uso de memória e esta palestra vai desmistificar muitos desses conceitos que são válidos para Ruby mas também para Java e outras VMs.

The world in which we monitor software is growing more complex every year. There are increasingly more ways to run server-side software, with many more independent services and more points of failures, the list goes on! On the plus side, there’s a lot of great tools and patterns being developed to try and make things simple to assess and understand. This talk covers how metrics and monitoring can be leveraged in a variety of different ways, auto-discovering applications and their usage of databases, caches, load balancers, etc, setting up and tearing down dashboards and monitoring automatically for services and instances, and more.
We’ll also talk about how you can accomplish all this with a global view of your systems using both Prometheus and Graphite with M3, our open source metrics platform. We’ll take a deep dive look at how we use M3DB, distributed aggregation with the M3 aggregator and the M3 Kubernetes operator to horizontally scale a metrics platform in a way that doesn’t cost outrageous amounts to run with a system that’s still sane to operate with petabytes of metrics data.

FOSDEM 2020: Querying over millions and billions of metrics with M3DB's indexRob Skillington
The cardinality of monitoring data we are collecting today continues to rise, in no small part due to the ephemeral nature of containers and compute platforms like Kubernetes. Querying a flat dataset comprised of an increasing number of metrics requires searching through millions and in some cases billions of metrics to select a subset to display or alert on. The ability to use wildcards or regex within the tag name and values of these metrics and traces are becoming less of a nice-to-have feature and more useful for the growing popularity of ad-hoc exploratory queries.
In this talk we will look at how Prometheus introduced the concept of a reverse index existing side-by-side with a traditional column based TSDB in a single process. We will then walk through the evolution of M3’s metric index, starting with ElasticSearch and evolving over the years to the current M3DB reverse index. We will give an in depth overview of the alternate designs and dive deep into the architecture of the current distributed index and the optimizations we’ve made in order to fulfill wildcards and regex queries across billions of metrics.
early benchmarks on pre-release Gnocchi v4. includes benchmark comparison between all-ceph v3.x driver versus all-ceph v4 driver. also, shows benchmark using redis+ceph deployment.
Abstract: At DataRobot we deal with automation challenges every day. This talk will give insight into how we use Python tools built around Ansible, Terraform, and Docker to solve real-world problems in infrastructure and automation.
Gisting is an implementation of Google\'s MapReduce framework for processing and extracting useful information from very large data sets. At the time of this writing, the code is available for PREVIEW at http://github.com/mchung/gisting. I am currently working to release this framework for general usage.

Graal in GraalVM - A New JIT Compiler
オラクル社からGraalVMというものが発表され、話題を呼んでいます。GraalVMはHotSpot VM上に新しいJITコンパイラGraalと言語実装用フレームワーク/ASTインタプリタであるTruffle、さらにネイティブイメージ作成機能とその実行に使われるSubstrateVMを併せ持ったものです。すでにTruffleを使用したJavaScriptやRuby、R、Pythonの実装も提供されており、これらの言語とJavaはコードから相互に呼び出しができます。このセッションではGraalVMを概観したあと、JITコンパイラGraalにとくに注力して解説します。GraalとTruffleはOracle Labsとヨハネス・ケプラー大学で共同研究されており、多くの論文が発表されています。HotSpotのJITコンパイラとパフォーマンスや構造などを比較しつつ、GraalのJITコンパイルのテクニックについてもいくつか触れます。とにかく、私がGraalをとても好きなのです。デモも実施しつつ、Graalのすごさを伝えられればと考えています。
Jvm & Garbage collection tuning for low latencies applicationQuentin Ambard
G1, CMS, Shenandoah, or Zing? Heap size at 8GB or 31GB? compressed pointers? Region size? What is the maximum break time? Throughput or Latency... What gain? MaxGCPauseMillis, G1HeapRegionSize, MaxTenuringThreshold, UnlockExperimentalVMOptions, ParallelGCThreads, InitiatingHeapOccupancyPercent, G1RSetUpdatingPauseTimePercent, which parameters have the most impact?
We will discuss most popular ORM libraries and will perform a brief comparison of them. Also we will see some GORM-specific implementation of query result caching.
Bits of Advice for the VM Writer, by Cliff Click @ Curry On 2015curryon
http://curry-on.org/2015/sessions/bits-of-advice-for-vm-writers.html
This is a talk about the choices one makes when building a Virtual Machine. Many of these choices aren’t even obviously being made when you first get the machine running - it’s not until years later when you look at your limitations that you even realize there was a choice. There’s the obvious Big VM (server, desktop, laptop, cell phone?) vs Small VM (embedded device, cell phone?) choice. But also: GC-or-no-GC. Portable or not (X86 vs ARM? vs Power/Sparc/tiny-DSP)? Multi-threaded or not? Run any “native” code - or only highly cooperative code? Run inside a pre-emptive multi-tasking OS? Or bare metal? Interpret bytecodes/p-codes vs dumb template-JIT vs Multi-tier-highly-optimizing-JIT? The set of choices goes on and on.
Most of these choices interact in Bad Ways… and usually the interactions are not obvious until long after the design decisions are made and locked in. And worse: most of the choices have to be made from the start, when you don’t really know the answers. Coding for yourself & your PhD advisor? Coding for a fortune-1000 company? Coding for the Internet-Scale-Masses? All different scenarios, with radically different goals. While the talk is based on my experience with the HotSpot Java VM, the bits of advice only loosely tied to Java, and can equally be applied to a host of other (VM) hosted languages.
Bio:
Cliff Click is the CTO and Co-Founder of H2O, makers of H2O, the open source math and machine learning engine for Big Data. Cliff wrote his first compiler when he was 15 (Pascal to TRS Z-80!), although Cliff’s most famous compiler is the HotSpot Server Compiler (the Sea of Nodes IR). Cliff helped Azul Systems build an 864 core pure-Java mainframe that keeps GC pauses on 500Gb heaps to under 10ms, and worked on all aspects of that JVM. Before that he worked on HotSpot at Sun Microsystems, and was at least partially responsible for bringing Java into the mainstream. Cliff is invited to speak regularly at industry and academic conferences and has published many papers about HotSpot technology. He holds a PhD in Computer Science from Rice University and about 20 patents.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

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.

Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
Let's dive deeper into the world of ODC! Ricardo Alves (OutSystems) will join us to tell all about the new Data Fabric. After that, Sezen de Bruijn (OutSystems) will get into the details on how to best design a sturdy architecture within ODC.

4. "G1 GC is an incremental parallel compacting
GC that provides more predictable pause times
compared to CMS GC and Parallel Old GC. By
introducing a parallel, concurrent and multi-
phased marking cycle, G1 GC can work with
much larger heaps while providing reasonable
worst-case pause times."
22. • Slots de mesmo tamanho (não há problema com
fragmentação)
• Quanto mais heaps, mais lento
• Fase de marcação conservadora
• pode haver “leaks” (ex. constantes)
• Processo “Stop-the-World"
64. • “Stop-and-Copy”
• Sweep precisa ir slot a slot, neste é só considerar
tudo no primeiro heap como livre
• Gerenciamento interno de ponteiros
• Feito para corrigir fragmentação
• Ruby tem slots de mesmo tamanho
• Não suporta Copy-on-Write
75. • Partial Markings, Lazy Sweeps = Menos Stop
• Shady objects não vão para o Tomb
• Write Barriers (referência old para new - non-Shady only)
• Compatível com extensões C (Shady)
• Objetos em Tomb só são remarcados em Full Mark
