Handling inline assembly in Clang and LLVMMin-Yih Hsu

The document discusses how inline assembly is processed in Clang and LLVM. It outlines the target-specific logic involved at each stage, including operand constraint validation in Clang, lowering operands to LLVM IR, and printing different operand types in the assembler. Target-specific callbacks for inline assembly handling are scattered throughout Clang and LLVM. The goals are to learn the inline assembly workflow and provide documentation for backend developers to add support.

Recursive Query ThrowdownKarwin Software Solutions LLC

MySQL 8 introduces support for ANSI SQL recursive queries with common table expressions, a powerful method for working with recursive data references. Until now, MySQL application developers have had to use workarounds for hierarchical data relationships. It's time to write SQL queries in a more standardized way, and be compatible with other brands of SQL implementations. But as always, the bottom line is: how does it perform? This presentation will briefly describe how to use recursive queries, and then test the performance and scalability of those queries against other solutions for hierarchical queries.

Golang 101宇傅

The document provides an introduction to the Go programming language. Some key points: - Go was designed by Google to handle large scale software development with thousands of developers and machines. It focuses on concurrency, simplicity, and reliability. - Some core features of Go include goroutines for lightweight threads, channels for communication between goroutines, and interfaces for abstraction. - Go aims to compile quickly to machine code for performance and packages into single binaries for easy deployment. - The document demonstrates building a basic web server in Go and encourages hands-on learning through its tour and examples.

CQL Under the HoodRobbie Strickland

As a reformed CQL critic, I'd like to help dispel the myths around CQL and extol its awesomeness. Most criticism comes from people like me who were early Cassandra adopters and are concerned about the SQL-like syntax, the apparent lack of control, and the reliance on a defined schema. I'll pop open the hood, showing just how the various CQL constructs translate to the underlying storage layer--and in the process I hope to give novices and old-timers alike a reason to love CQL.

Hearts Of Darkness - a Spring DevOps ApocalypseJoris Kuipers

In this talk Joris shares several real-life failure cases concerning running Spring applications in production. Examples include services being killed because of health check issues, Micrometer metrics getting lost, circuit breakers never closing after opening, OOM errors caused by unbounded queues and other nightmarish scenario’s. Not only will you come to understand how these problems could sneak through staging to make their way to production, you will also be given practical tips on how to avoid these things from happening to your own applications. Otto von Bismarck famously said “Fools say that they learn by experience. I prefer to profit by others’ experience”. Don’t be a fool, and profit by viewing this talk!

Coroutines in KotlinAlexey Soshin

Coroutines are Kotlin's solution for concurrency and allow doing something else while waiting for results. They avoid issues with threading like memory usage and bottlenecks. Coroutines use suspending functions to pause execution and switch to other coroutines. They can be cancelled, have timeouts set, and structured hierarchically with jobs. Common coroutine patterns include producers that return values on channels and actors that receive messages on inbound channels. Coroutines are backed by event loops and may require yield() if CPU bound to allow other coroutines to run.

Q2.12: Debugging with GDBLinaro

GDB can debug programs by running them under its control. It allows inspecting and modifying program state through breakpoints, watchpoints, and examining variables and memory. GDB supports debugging optimized code, multi-threaded programs, and performing tasks like stepping, continuing, and backtracing through the call stack. It can also automate debugging through commands, scripts, and breakpoint actions.

Understand more about CYi-Hsiu Hsu

The code compares pointers and arrays in C by printing their sizes and string lengths. When a string literal is assigned to a pointer, sizeof(pointer) returns the pointer size rather than the string length, while sizeof(array) returns the full array size including the null terminator. strlen(pointer) and strlen(array) both return the string length excluding the null terminator. When an array is passed to a function, it converts to a pointer and sizeof then returns the pointer size rather than full array size.

Intro to GoClarence Bakirtzidis

Python to goWeng Wei

The author explains why they switched from primarily using Python to primarily using Go for serious projects. Some key reasons include that Go has better performance, code quality, testing, and concurrency features compared to Python. While Python is still good for hobby projects, Go enforces error handling, has built-in profiling tools, and makes deployment easier due to compiling to a single binary.

그렇게 커미터가 된다: Python을 통해 오픈소스 생태계 가르치기Jeongkyu Shin

2018년 8월 19일 PyCon KR 2018에서 오픈소스 교육과 Python을 주제로 발표한 내용입니다. # 개요 오픈소스 및 오픈소스 개발 방법론은 현대 프로그래밍 개발 및 생태계에서 가장 중요한 축을 담당하고 있다. 전세계 유수의 IT 기업들은 거의 모두 오픈소스를 사용하며, 자체 결과물을 오픈소스로 공개하고 있다. 또한 윈도우 및 맥오에스, 리눅스 및 안드로이드를 비롯한 운영체제들 또한 오픈소스로 개발되거나 또는 오픈소스 커뮤니티 방법론을 이용해 테스트되고 있다. 최근 오픈소스 소프트웨어 및 개발 방법론은 과거 컴퓨터 언어 및 개발 과정과 큰 차잇점이 있다. 가장 큰 차잇점은 네트워크에 의해 가속화된 생태계의 속도이다. 최근 오픈소스 소프트웨어 생태계의 경우 개발 방법론, 기술, 라이브러리 및 프로젝트들이 등장하고 성숙하는 과정에 걸리는 시간이 기존 컴퓨터 생태계에 비해 굉장히 짧다. 따라서 오픈소스 참여 기술보다는 오픈소스 생태계 및 변화의 흐름을 이해하는 것이 더 중요해지고 있다. 따라서 일반적인 대학 교과과정의 타임 프레임을 적용하여 과목을 설계하기에는 무리가 있다. 이 세션에서는 오픈소스 소프트웨어 대학 교육 과정을 설계하고 2년간 강의하며 겪은 다양한 경험을 Python 언어를 중심으로 다룬다. Python은 초기 접근이 용이하여 21세기 초부터 많은 대학이 기초 프로그래밍 언어로 선택하고 있어, 오픈소스 소프트웨어 방법론 교과 과정의 주 언어로 선택하였다. 교과 과정이 지향하는 바는 프로그래밍과 오픈소스 문화 두가지이다. 이를 반영한 교육 과정 설계 시 주의한 점들과, 2년간의 경험 끝에 잘못 생각한 것으로 판단하게 된 몇가지에 대해 간단히 소개한다. 오픈소스 소프트웨어 교육 과정에서는 초반부 오픈소스의 역사, 문화에 대해 학습한 방법과, Python 기반의 오픈소스 프로젝트 진행 과정에서 경험한 다양한 사례 및 장단점에 대해 소개한다. 개발 과정에서는 GitHub을 이용한 협업, 오픈소스 소프트웨어를 무에서 시작하거나 포크해서 시작하는 과정, 공동 작업에서의 PEP 준수의 중요성, 컨트리뷰터,커미터,메인테이너 결정 및 운영과, 팀 내 충돌, 그리고 Code of Conduct를 만들었던 과정을 차례로 설명한다. 또한 배포 패키지 개발을 위해 pypi를 사용하고, manpage로 매뉴얼을 준비하는 과정 및 python 패키지 제작시 겪는 몇몇 허들에 대해서도 소개한다. 마지막으로 과정에서 동기 부여에 대해 고민한 여러 생각 및 경험과 함께, 수업 과정에서 사용한 오리지널 프로젝트 원저자와의 GitHub을 통한 소통 및 오픈소스 경험의 확장 과정을 소개한다.

How and Why you can and should Participate in Open Source Projects (AMIS, Sof...Lucas Jellema

For a long time I have been reluctant to actively contribute to an open source project. I thought it would be rather complicated and demanding – and that I didn't have the knowledge or skills for it or at the very least that they (the project team) weren't waiting for me. In December 2021, I decided to have a serious input into the Dapr.io project – and now finally to determine how it works and whether it is really that complicated. In this session I want to tell you about my experiences. How Fork, Clone, Branch, Push (and PR) is the rhythm of contributing to an open source project and how you do that (these are all Git actions against GitHub repositories). How to learn how such a project functions and how to connect to it; which tools are needed, which communication channels are used. I tell how the standards of the project – largely automatically enforced – help me to become a better software engineer, with an eye for readability and testability of the code. How the review process is quite exciting once you have offered your contribution. And how the final "merge to master" of my contribution and then the actual release (Dapr 1.6 contains my first contribution) are nice milestones. I hope to motivate participants in this session to also take the step yourself and contribute to an open source project in the form of issues or samples, documentation or code. It's valuable to the community and the specific project and I think it's definitely a valuable experience for the "contributer". I looked up to it and now that I've done it gives me confidence – and it tastes like more (I could still use some help with the work on Dapr.io, by the way).

Kubernetes secret introductionEvan Lin

This document discusses Kubernetes secrets, service accounts, and authentication. It covers how secrets store sensitive information like passwords or SSH keys. Service accounts associate secrets with pods or provide credentials for processes. The document demonstrates how to create secrets and service accounts, and use secrets in pods through environment variables or mounted volumes. It also lists some OAuth server implementations for authentication.

Consistent hashing algorithmic tradeoffsEvan Lin

This document summarizes several consistent hashing algorithms: Mod-N hashing is simple but makes adding or removing servers difficult as it may require reconstructing the entire hashing table. Consistent hashing addresses this by using two hash functions - one for data and one for servers, placing them on a ring to distribute data. Jump hashing improves load distribution and reduces space usage to O(1) but does not support arbitrary node removal. Maglev hashing provides constant-time lookups but slow generation on node failure. Later algorithms aim to improve aspects like bounded load distribution and memory usage versus lookup speed. Overall, consistent hashing algorithms involve tradeoffs between these factors.

This document compares Kubernetes and Mesos, discussing their architectures, support for multiple schedulers and container runtimes, suitability for standalone big data workloads, and container network plugins. It notes that big companies initially chose Mesos because it had more production usage history before Kubernetes 1.6. It also provides a timeline comparing feature releases between 2016-2017 for both platforms.

iThome Cloud Summit: The next generation of data center: Machine Intelligent ...Evan Lin

隨著時代的演進，管理機器的方式也隨著慢慢進化。隨著一台台機器的管理方式，變成了集群（Cluster）的管理方式．而應用程式的部屬方始也從最原始的實體機部署，到了虛擬機器（VM）甚至到了容器（Container）的部署方式。 Kubernetes, DCOS 與 Docker Swarm 就是結合了容器部署與機器集群的管理方式的一個管理套件。但是集群的部屬方式並不代表你可以節省部署與維護的人力，因為隨著集群的數量變大，緊接來著就是需要更多管理的技巧。比如說：如何有效地管理集群的使用率? 如何讓集群內閒置機器能夠自動關閉? 如何有效地自動擴展你的集群? 如何讓集群偵測惡意攻擊或是自我修復? 講者將會帶來一個新的觀念，就是一個具有機器智能的集群管理系統。結合時下最受歡迎的機器學習架構（SMACK）與深度學習代表的 Tensorflow 如何讓你的集群能夠更有效地分析使用量，進而讓你的集群變得有智能。變成下一代的機器智能集群（Machine Intelligent Cluster）。

Who Watches the Watchmen (SciFiDevCon 2025)Allon Mureinik

Tests, especially unit tests, are the developers’ superheroes. They allow us to mess around with our code and keep us safe. We often trust them with the safety of our codebase, but how do we know that we should? How do we know that this trust is well-deserved? Enter mutation testing – by intentionally injecting harmful mutations into our code and seeing if they are caught by the tests, we can evaluate the quality of the safety net they provide. By watching the watchmen, we can make sure our tests really protect us, and we aren’t just green-washing our IDEs to a false sense of security.

TestMigrationsInPy: A Dataset of Test Migrations from Unittest to Pytest (MSR...Andre Hora

Unittest and pytest are the most popular testing frameworks in Python. Overall, pytest provides some advantages, including simpler assertion, reuse of fixtures, and interoperability. Due to such benefits, multiple projects in the Python ecosystem have migrated from unittest to pytest. To facilitate the migration, pytest can also run unittest tests, thus, the migration can happen gradually over time. However, the migration can be timeconsuming and take a long time to conclude. In this context, projects would benefit from automated solutions to support the migration process. In this paper, we propose TestMigrationsInPy, a dataset of test migrations from unittest to pytest. TestMigrationsInPy contains 923 real-world migrations performed by developers. Future research proposing novel solutions to migrate frameworks in Python can rely on TestMigrationsInPy as a ground truth. Moreover, as TestMigrationsInPy includes information about the migration type (e.g., changes in assertions or fixtures), our dataset enables novel solutions to be verified effectively, for instance, from simpler assertion migrations to more complex fixture migrations. TestMigrationsInPy is publicly available at: https://github.com/altinoalvesjunior/TestMigrationsInPy.

What Do Contribution Guidelines Say About Software Testing? (MSR 2025)Andre Hora

Software testing plays a crucial role in the contribution process of open-source projects. For example, contributions introducing new features are expected to include tests, and contributions with tests are more likely to be accepted. Although most real-world projects require contributors to write tests, the specific testing practices communicated to contributors remain unclear. In this paper, we present an empirical study to understand better how software testing is approached in contribution guidelines. We analyze the guidelines of 200 Python and JavaScript open-source software projects. We find that 78% of the projects include some form of test documentation for contributors. Test documentation is located in multiple sources, including CONTRIBUTING files (58%), external documentation (24%), and README files (8%). Furthermore, test documentation commonly explains how to run tests (83.5%), but less often provides guidance on how to write tests (37%). It frequently covers unit tests (71%), but rarely addresses integration (20.5%) and end-to-end tests (15.5%). Other key testing aspects are also less frequently discussed: test coverage (25.5%) and mocking (9.5%). We conclude by discussing implications and future research.

Scaling GraphRAG: Efficient Knowledge Retrieval for Enterprise AIdanshalev

If we were building a GenAI stack today, we'd start with one question: Can your retrieval system handle multi-hop logic? Trick question, b/c most can’t. They treat retrieval as nearest-neighbor search. Today, we discussed scaling #GraphRAG at AWS DevOps Day, and the takeaway is clear: VectorRAG is naive, lacks domain awareness, and can’t handle full dataset retrieval. GraphRAG builds a knowledge graph from source documents, allowing for a deeper understanding of the data + higher accuracy.

How Valletta helped healthcare SaaS to transform QA and compliance to grow wi...Egor Kaleynik

This case study explores how we partnered with a mid-sized U.S. healthcare SaaS provider to help them scale from a successful pilot phase to supporting over 10,000 users—while meeting strict HIPAA compliance requirements. Faced with slow, manual testing cycles, frequent regression bugs, and looming audit risks, their growth was at risk. Their existing QA processes couldn’t keep up with the complexity of real-time biometric data handling, and earlier automation attempts had failed due to unreliable tools and fragmented workflows. We stepped in to deliver a full QA and DevOps transformation. Our team replaced their fragile legacy tests with Testim’s self-healing automation, integrated Postman and OWASP ZAP into Jenkins pipelines for continuous API and security validation, and leveraged AWS Device Farm for real-device, region-specific compliance testing. Custom deployment scripts gave them control over rollouts without relying on heavy CI/CD infrastructure. The result? Test cycle times were reduced from 3 days to just 8 hours, regression bugs dropped by 40%, and they passed their first HIPAA audit without issue—unlocking faster contract signings and enabling them to expand confidently. More than just a technical upgrade, this project embedded compliance into every phase of development, proving that SaaS providers in regulated industries can scale fast and stay secure.
