Java script and json
Java script and jsonIslam Abdelzaher The document provides an overview of JavaScript and JSON, explaining that JSON is a format for sharing data that is derived from JavaScript and is used to transfer data between a server and browser. It describes the basic syntax of JSON, including that it uses name-value pairs separated by commas within curly brackets for objects and square brackets for arrays, and supports strings, numbers, booleans, arrays, objects and null as data types. Examples are given to illustrate JSON syntax and how it can be parsed in JavaScript to convert it into a JavaScript object.
ETL into Neo4j

Introduction to the DOM
Introduction to the DOMtharaa abu ashour The document discusses the Document Object Model (DOM), which defines a standard for accessing and manipulating HTML and XML documents.

Voz Pasiva
Voz Pasivaestephani villalobos La voz pasiva en español solo puede construirse con verbos transitivos, aunque algunos como 'haber' o 'tener' no permiten esta construcción. Existen dos formas de voz pasiva: la pasiva analítica y la pasiva refleja, siendo esta última más común en el habla cotidiana. La voz pasiva se enfoca en la acción en lugar de quién la realiza, lo que puede resultar en una expresión más cortés.
JSON-RPC Proxy Generation with PHP 5
JSON-RPC Proxy Generation with PHP 5Stephan Schmidt The document provides an overview of a presentation given by Stephan Schmidt on connecting PHP and JavaScript using JSON-RPC. Some key points:
- It discusses the classic web application model and how business logic resides solely on the server
- With Web 2.0, presentation logic moved to the client but business logic still resides on the server
- The remote proxy pattern can be used to expose server-side business logic as JavaScript objects, making remote calls transparent to the client
- This is done by serializing calls to JSON and making HTTP requests to a JSON-RPC server implemented in PHP
- The server uses reflection to dynamically call the relevant PHP methods and return responses also serialized to JSON

社内勉強会資料_Chain of Thought .NABLAS株式会社 本資料「To CoT or not to CoT?」では、大規模言語モデルにおけるChain of Thought（CoT）プロンプトの効果について詳しく解説しています。
CoTはあらゆるタスクに効く万能な手法ではなく、特に数学的・論理的・アルゴリズム的な推論を伴う課題で高い効果を発揮することが実験から示されています。
一方で、常識や一般知識を問う問題に対しては効果が限定的であることも明らかになりました。
複雑な問題を段階的に分解・実行する「計画と実行」のプロセスにおいて、CoTの強みが活かされる点も注目ポイントです。
This presentation explores when Chain of Thought (CoT) prompting is truly effective in large language models.
The findings show that CoT significantly improves performance on tasks involving mathematical or logical reasoning, while its impact is limited on general knowledge or commonsense tasks.

OCS Group SG - HPHT Well Design and Operation - SN.pdf
OCS Group SG - HPHT Well Design and Operation - SN.pdfMuanisa Waras This course is delivered as a scenario-based course to
provide knowledge of High Pressure and High-Temperature (HPHT) well design, drilling and completion operations. The course is specifically designed to provide an
understanding of the challenges associated with the design
and construction of HPHT wells. The course guides the
participants to work through the various well design
aspects starting from a geological well proposal with an
estimated formation pressure and temperature profile.
Working with real well data allows the participants to learn
not only theory, technicalities and practicalities of drilling
and completing HPHT wells but it also ensures that participants gain real experience in understanding the HPHT issues.

- 2. JSON - What is JSON? Why JSON? - JSON Syntax - JSON examples - Accessing JSON - JSON From/To String - JSON online tools - References
- 3. What is JSON? Why JSON? - What is JSON? - JSON stands for JavaScript Object Notation - JSON is a lightweight data-interchange format - JSON is "self-describing" and easy to understand - JSON is language independent - Why JSON? - Since the JSON format is text only, it can easily be sent to and from a server, and used as a data format by any programming language.
- 4. JSON Syntax - Data is in name/value pairs - Data is separated by commas - Curly braces hold objects - Square brackets hold arrays - Name: can be single word, dashed words, underscore words, or dotted words. - {"age": 44,"age_i":55, "age.p":100};
- 5. JSON Syntax
- 6. Accessing JSON - Name is single word: - User.name - Name is any type, single, dashed, underscored, or dotted. - user[‘name’] or user[“name”]
