Scaling Drupal in AWS Using AutoScaling, Cloudformation, RDS and more
Given at DrupalJam 2015 - Netherlands.
This presentation explains some of the fundamental issues you have to overcome when designing software for distributed systems that can fail. Also called "Cloud" in other terminologies. The presentation uses AWS components to explain these fundamentals and uses Drupal as the example application. The example is by no means perfect, but gives you a good idea how to design your system from scratch.
Technologies used:
Cloudformation
EC2 Instances
RDS MySQL Database
Elastic Load Balancer
ElastiCache (Memcache)
Example can be found here:
https://gist.github.com/nickveenhof/601c5dc1b76ff26896bf
Take note that the example does not include components such as VPC for simplicity, but it is highly recommended to add this.
Domino OSGi Development
This document provides an overview of creating and deploying OSGi plugins for the Domino HTTP task. It discusses setting up the Eclipse development environment with the necessary prerequisites like the Domino OSGi target platform and the Notes.jar plugin. It then demonstrates creating a simple "Hello World" servlet plugin that runs on the Equinox HTTP service, and deploying/debugging it using the PDE tool directly from Eclipse.

Attacking REST API
This document discusses REST APIs and how to attack them. It begins by explaining what REST APIs are and how they map CRUD operations to HTTP verbs like GET, POST, PUT, DELETE. It then covers REST architecture constraints like using resources and representations. The document outlines how to interact with APIs through requests and responses. It provides examples of enumeration, injection, authentication vulnerabilities and how to test authorization, rate limiting, SSL and information disclosure. It concludes with discussing cross-site request forgery attacks on REST APIs.

PIM, PAM and PUM have different meanings, and interpretations, to different people. For the most part the concepts around these three far-ranging topics intersect, and for the most part we are talking about the same thing. PIM, privileged identity management; PUM, privileged user management; and PAM, privileged account management OR privileged access management. All three of these acronyms revolve around a few simple concepts: who can get to a server, how they can get to a server and what they can do when they get there.

Server Sent Events, Async Servlet, Web Sockets and JSON; born to work together!
This session focuses on how Java EE 7 provides extensive set of new and enhanced features to support standards like HTML5, WebSockets, and Server Sent Events among others.In this session we will show how these new features are designed and matched to work together for developing lightweight solutions matching end users high expectation from a web application’s responsiveness. The session will cover best practices and design patterns governing application development using JAX-RS 2.0, Async Servlet, and JSON-P (among others) as well as iterating over the pitfalls that should be avoided. During the session we will show code snippets and block diagrams that clarify use of APIs coming from the demo application we will show at the end.

LINEのFIDO導入と将来展望
LINE is introducing FIDO authentication to improve security for account registration, login, and transactions across its various services. Potential use cases for FIDO include social login, setting confirmation, desktop app login, transaction authentication for payments, IoT control, and hands-free IoT control. LINE plans to integrate FIDO using UAF and FIDO2 standards and deploy an authentication platform to serve as an identity provider across its services and other apps and websites by 2020.
SSO Strategy Implementation Considerations
The document discusses considerations for implementing a single sign-on (SSO) strategy. It recommends first agreeing on terminology, then assessing the current authentication and authorization landscape. The document outlines a vision of SSO utopia and compares approaches of building an in-house SSO solution versus purchasing a vendor framework. It proposes a roadmap including defining terms, assessing vendors, integrating new and existing applications, and production deployment.

dominocamp2022.t1s1.dde.pptx
New features in Domino Designer include enhancements to the Domino Query Language (DQL) like improved indexing capabilities and support for additional data types. The NotesDominoQuery class allows compiling and running DQL queries from LotusScript and Java. Other additions are the NotesGPS class for location data and @Platform conditional compilation. The C API SDK was updated and OSGI Tasklet Service support was added.
Protocol Buffers
Protocol Buffers are a language-neutral, platform-neutral way of serializing structured data developed by Google to deal with problems of scale. Data formats are defined using .proto files which are then compiled to generate data access classes. This allows structured data to be serialized and transmitted efficiently across various languages and platforms while maintaining backward/forward compatibility. Protocol Buffers offer advantages over other solutions like XML in being more efficient, compact and faster. They have found many use cases at Google and other companies for messaging, data storage and transmission.

GDB와 strace로 Hang 걸린 Python Process 원격 디버깅
Python 프로그램을 디버깅하실 때 어떤 툴을 사용하시나요? 아무래도 가장 많이 사용하고 계신 툴은 PyCharm이 아닐까 싶습니다. PyCharm은 JetBrains에서 만든 GUI 환경에서 사용할 수 있는 Python IDE입니다.
PyCharm은:
로컬 컴퓨터에서 디버깅 모드로 (PyDev로) Python 프로세스를 실행할 수 있습니다.
로컬 컴퓨터에서 실행 중인 Python 프로세스에 Attach해 디버깅할 수 있습니다.
원격 서버에서 디버깅 모드로 (PyDev로) Python 프로세스를 실행할 수 있습니다.
하지만 원격에서 동작하고 있는 프로세스에 디버거를 Attach하는 기능은 제공하지 않고 있습니다. 또한 Python 디버깅 모듈인 pdb를 사용하여도 동작하고 있는 프로세스에 Attach하는 것은 지원하고 있지 않습니다.
로컬 환경에서는 문제 없이 돌아갔던 Python 프로그램이 원격 서버에서는 아무런 로그 없이 멈춰 버리는 경우 어디서부터 손을 대야 할지 정말 막막합니다. 이 때 GDB와 strace를 이용하면 어디에서 문제가 발생했는지 진단할 수 있습니다. 이 세션에서는 GDB와 strace를 이용해 디버깅하여 원격 리눅스 서버에서 Python Process가 Hang 되어 버리는 문제를 진단하고 해결했던 경험을 공유하려고 합니다.

LLVM UB Optimization
The document discusses undefined behavior (UB) in programs and its relationship to compiler optimizations. It introduces the concept of poison values to represent violations of assumptions. The freeze instruction is proposed as a way to handle UB and inconsistencies caused by optimizations like global value numbering and loop unswitching. Freezing values before operations prevents miscompilations by treating undefined inputs as nondeterministic rather than undefined.

This document discusses using The Composable Architecture (TCA) with SwiftUI to build a GitHub search app. It introduces TCA concepts like state, actions, reducers, effects and dependencies. It provides examples of modeling a counter app with TCA and connecting it to the GitHub API. The document outlines workshops to apply TCA in SwiftUI, including setting up state management, handling side effects, and implementing real-time search. TCA is said to enable better state management, easier debugging, improved testability and modular code composition compared to alternatives like MVVM.
Swift for tensorflow
Swift is proposed as a next-generation platform for TensorFlow that could provide benefits over Python like improved performance, type safety, and enabling automatic differentiation at compile time. However, Python currently dominates the machine learning ecosystem. Swift and Python are intended to have a complementary relationship, with each suited to different use cases. Examples show comparable MNIST implementations in both Swift and Python for TensorFlow.

- 7. CLA 서명 • https://www.chromium.org/developers/contributing-code/external-contributor-checklist • 컨트리뷰터 체크리스트 • https://cla.developers.google.com/ • CLA 서명 사이트 • 처음 패치를 올릴때 AUTHORS에 이름, 메일 주소를 입력 • 동일한 이름으로 CLA 서명
- 8. Gerrit에 upload • 브랜치를 새로 만든 뒤 소스코드 수정. • depot_tools를 통해 git cl upload • https://gerrit-review.googlesource.com/Documentation/user-upload.html • Review받기 • 해당 코드의 AUTHORS에 있는 사람혹은 이슈를 올린 사람을 리 뷰어로 추가.
- 9. Merged, issue closed • gerrit에서 리뷰어 추가하고 코드 리뷰받기 • IRC, mailing list 등을 통해 리뷰 요청가능! • 리뷰어가 빌드 큐에 넣어줌 • Buildbot이 test run을 하고 이상 없으면 머지됨 • issue closed 혹은 다음 patch에 대해 논의
- 10. Tip! • G+그룹 https://www.chromium.org/developers/discussion-groups • 관련 없는 테스트가 flaky한 경우 종종 실패하는 경우가 있는데 buildbot이 여러번 run하니 걱정하지 말자. • 입문자들에게 매우 친절하다.
