React v18 introduces new features like concurrent rendering and automatic batching that allow updates to occur concurrently without blocking the UI. Concurrent rendering allows parts of the UI to update independently while other processes continue in memory. Automatic batching groups multiple state updates into a single re-render for better performance. StrictMode now causes effects with empty dependencies to run twice to support new React features, but this is only an issue if offscreen rendering or Suspense is used.

Get Started with ReactJS 18 Development Services_ New Features and Updates.pptx
React 18 introduces several new features including concurrent rendering, strict mode, transitions, automatic batching, and new suspense features. Concurrent rendering allows React to interrupt, resume, or stop renders. Strict mode improves component reusability. Transitions help prioritize urgent vs non-urgent updates. Automatic batching groups state updates without re-renders. New suspense features like delay transition and placeholder throttle improve performance. Overall, React 18 enhances responsiveness and optimization.
Introduction to Redux.pptx
This document introduces Redux, a state management library for JavaScript apps. It discusses why state management is needed, other approaches like Flux and MobX, and how Redux addresses these issues using principles of single source of truth, immutable state updates via pure functions, and unidirectional data flow. Key aspects of Redux like actions, action creators, reducers, and connecting React components to the store are explained. Considerations for when Redux is a good fit and potential gotchas are also covered.
Performance tips for Symfony2 & PHP
The document provides performance tips for Symfony2 and PHP applications. It recommends starting by measuring performance before and after optimizations to identify where to focus efforts. Key areas to optimize include services like using PHP opcache, architecture like caching, and code through techniques like moving calculations out of loops. Symfony-specific tips involve using bytecode caching, lazy-loading services, and caching in general. The overall message is to prioritize scalability and only optimize after identifying bottlenecks through measurement and profiling.

X Server Multi-rendering for OpenGL and PEX
To support OpenGL and PEX rendering within the Silicon Graphics X server without compromising interactivity, we devised and implemented a scheme named multi-rendering. Making minimal changes to the X Consortium sample server’s overall structure, the scheme allows independent processes within the X server’s address space to perform OpenGL rendering asynchronously to the X server’s main thread of execution. The IRIX operating system’s process share group facility, user-level and pollable semaphores, and support for virtualized direct access rendering are all leveraged to support multi-rendering. The Silicon Graphics implementation of PEX also uses the multi-rendering facility and works by converting rendering requests into OpenGL commands. Multi-rendering is contrasted with other schemes for improving server interactivity. Unlike co-routines, multi-rendering supports multi-processing; unlike multi-threading, multi-rendering requires minimal locking overhead.
Presented at the 8th Annual X Technical Conference, Boston, Mass., January 25, 1994.

The Basics of programming
The document provides an overview of programming for robotics competitions, including what is needed, how to program using C language in the MPLAB environment, and how to associate programming elements with robot components and sensors. Key aspects covered include familiarizing yourself with important files like user_routines.c, programming commands like if/else statements and variables, and how programming maps to elements on the robot controller and operator interface.
Using Web Software Architecture in Traditional Desktop App Development
The development experience of desktop and web application is different, but their gap is getting closer. A modern JavaScript application also needs a build script for “compilation" for deployment like a desktop application.
At the same time, the desktop environment is adopting the web technology. Qt, being one of the most popular cross-platform development frameworks, introduced a language called QML in its 4.7 version. It provides a declarative way to design the user interface and handle user response by JavaScript. It is a solution to speed up the development time of making a user interface.
What happens if more web technology is being used on desktop development?
The speaker is going to share his experience in porting Flux/Redux to QML, promise chaining to C++, and his vision on future desktop development technology.

XPDDS17: Approach to Native Applications in XEN on ARM - Volodymyr Babchuk, E...The Linux Foundation
Today XEN comes to embedded systems, where it needs to be much closer to a hardware. In one hand hypervisor needs to mediate calls to Trusted Zone, control power, provide drivers for coprocessors, on other hand it needs to remain as small and as secure as possible. So natural approach is to offload all these tasks to something else (like stubdomain or native application).
ARM platform allow hypervisor to act as a common kernel by handling system calls from userspace.
In this talk Volodymyr will describe idea of native applications, compare them with stubdomains and share results of his Native Apps PoC.Dolibarr - What's new in 12.0 - Webinare 2020

Presentation
Microseconds matter in High Frequency Trading. This document discusses how software development for high frequency trading (HFT) requires optimizations for ultra-low latency. HFT systems make profits from many small, quick trades executed at very high speeds. Latency is critical for HFT systems to capture profitable opportunities and avoid losses. The document outlines various techniques for optimizing C++ code for latency, such as removing unnecessary operations from hot code paths, using memory pools instead of dynamic memory allocation, avoiding string operations, and improving branch prediction. It also discusses the importance of measuring system performance at a microsecond level.
React DOM/Virtual DOM
React, often stylized as React-dom, has taken the world of web development by storm. Recognizing the advantages of React and how it interacts with the Document Object Model (DOM) – a topic that often prompts the question, “what is DOM in React?” – is essential for both aspiring and seasoned developers. From the component-based approach and React DOM methods to the virtual DOM concept, React brings several benefits to the table.

COMPUTER ORGANIZATION.pptxbkobuujghuujjj
This document compares compilers and interpreters. A compiler translates high-level code into machine code before execution, while an interpreter converts each line of high-level code into machine code during execution. Compilers allow for optimization but require compilation, while interpreters allow for interactive development and debugging but have slower performance. In conclusion, the document explains the key differences between compilers and interpreters.

CHINA’S GEO-ECONOMIC OUTREACH IN CENTRAL ASIAN COUNTRIES AND FUTURE PROSPECT
The rivalry between prominent international actors for dominance over Central Asia's hydrocarbon
reserves and the ancient silk trade route, along with China's diplomatic endeavours in the area, has been
referred to as the "New Great Game." This research centres on the power struggle, considering
geopolitical, geostrategic, and geoeconomic variables. Topics including trade, political hegemony, oil
politics, and conventional and nontraditional security are all explored and explained by the researcher.
Using Mackinder's Heartland, Spykman Rimland, and Hegemonic Stability theories, examines China's role
in Central Asia. This study adheres to the empirical epistemological method and has taken care of
objectivity. This study analyze primary and secondary research documents critically to elaborate role of
china’s geo economic outreach in central Asian countries and its future prospect. China is thriving in trade,
pipeline politics, and winning states, according to this study, thanks to important instruments like the
Shanghai Cooperation Organisation and the Belt and Road Economic Initiative. According to this study,
China is seeing significant success in commerce, pipeline politics, and gaining influence on other
governments. This success may be attributed to the effective utilisation of key tools such as the Shanghai
Cooperation Organisation and the Belt and Road Economic Initiative.

- Exploiting IAM PassRole Misconfiguration
-Allows a user to pass a specific IAM role to an AWS service (ec2), typically used for service access delegation. Then exploit PassRole Misconfiguration granting unauthorized access to sensitive resources.
- Objective: Demonstrate how a PassRole misconfiguration can grant unauthorized access.
- Steps:
- Allow user to pass IAM role to EC2.
- Exploit misconfiguration for unauthorized access.
- Access sensitive resources.
- Exploiting IAM AssumeRole Misconfiguration with Overly Permissive Role
- An overly permissive IAM role configuration can lead to privilege escalation by creating a role with administrative privileges and allow a user to assume this role.
- Objective: Show how overly permissive IAM roles can lead to privilege escalation.
- Steps:
- Create role with administrative privileges.
- Allow user to assume the role.
- Perform administrative actions.
- Differentiation between PassRole vs AssumeRole

Advanced control scheme of doubly fed induction generator for wind turbine us...
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

precisely delineate tumor boundaries from magnetic resonance imaging (MRI)
scans holds profound implications for diagnosis. This study presents an ensemble convolutional neural network (CNN) with transfer learning, integrating
the state-of-the-art Deeplabv3+ architecture with the ResNet18 backbone. The
model is rigorously trained and evaluated, exhibiting remarkable performance
metrics, including an impressive global accuracy of 99.286%, a high-class accuracy of 82.191%, a mean intersection over union (IoU) of 79.900%, a weighted
IoU of 98.620%, and a Boundary F1 (BF) score of 83.303%. Notably, a detailed comparative analysis with existing methods showcases the superiority of
our proposed model. These findings underscore the model’s competence in precise brain tumor localization, underscoring its potential to revolutionize medical
image analysis and enhance healthcare outcomes. This research paves the way

Optimizing Gradle Builds - Gradle DPE Tour Berlin 2024
Sinan from the Delivery Hero mobile infrastructure engineering team shares a deep dive into performance acceleration with Gradle build cache optimizations. Sinan shares their journey into solving complex build-cache problems that affect Gradle builds. By understanding the challenges and solutions found in our journey, we aim to demonstrate the possibilities for faster builds. The case study reveals how overlapping outputs and cache misconfigurations led to significant increases in build times, especially as the project scaled up with numerous modules using Paparazzi tests. The journey from diagnosing to defeating cache issues offers invaluable lessons on maintaining cache integrity without sacrificing functionality.

React v18 alpha 発表
- 1. React v18 alpha 発表🎉 next
- 2. A gradual adoption strategy 通常のメジャーReact リリースに匹敵するレベルの労力で、 アプリケーションコードに最小限の変更を加えるか、 まったく変更を加えずにReact18 にアップグレードできます 17 もそんな感じでしたね。 next
- 3. 目玉その1 -Concurrent Rendering- 以前はConcurrent Mode と呼ばれていたあれです 並列レンダリング 一度DOM が更新/レンダリングされるとSTOP できない（ブロッキング） concurrent だと中断可能 キーを押した時にいつまで経ってもinput が反映されない… -> ブロッキングしているせい。入力フィールド を表示させつつ、メモリ内の処理が終わると更新後のレンダーを走らせることができる。 next
- 4. 目玉その1 -Concurrent Rendering- Concurrent Mode から変わったのはなぜ？ 必要な場所だけオプトインになった 0 - 100 だったMode とは違う 予定される機能たち startTransition ・・・コストの高い状態遷移においてUI の応答性を維持する useDefferedValue ・・・画面の重要度の低い部分の更新を先延ばしする <SuspenseList> ・・・ロードインジケータが表示される順序のコントロール next ` ` ` ` ` `
- 5. 目玉その2 -Automatic Batching- 連続して複数回state を更新すると、複数回再レンダリングが起きてしまう。 これを1 度のレンダリングで良いように進化! デフォルトでついているので、オプトアウト希望の場合は flushSync を使う。 バッチ処理とは、React が複数の状態の更新を1 つの再レンダリングにグループ化して、パフォーマンスを 向上させること next ` `
- 6. 目玉その3 -StrictMode でのuseEffect- useEffect(() => { /* ... */ }, []) でもuseEffect を二回走らせる(mount -> unmount -> mount) なぜこのタイミングで追加されたのか？ Concurrent Rendering の実装 Offscreen API の実装予定 Fast Refresh どれも複数回エフェクトが発火する可能性を孕む next https://github.com/reactwg/react-18/discussions/19 ` `
- 7. 目玉その3 -StrictMode でのuseEffect- 実装で注意するべき点は？ Offscreen やSuspense を使わなければ本番では大丈夫 将来的には怪しいので、 useRef を使いましょう。 今話し合われている内容 console.log が毎度呼び出されるのは辛い、ミュートする必要があるのでは？ 実際にはcleanup も走るので、副作用は（ちゃんと設計すれば）残らない next ` `
