#Json decode

[adventures-in-re]

wait so,,, how are you looking through the code??? i’m so curious and so so fascinating by what you’ve found

for the most part it's actually just a lot of asset mining. not 100%, there are some things i had to learn through deeper decompiling of C# scripts (although i'm still kind of trying to figure out efficient ways of decompiling the scripts, because while C# scripts are, in theory, super easy to decompile, Fictif and The Arcana use this thing that comes with Unity called il2cpp, which is basically code protection, and makes decompiling the scripts really goddam difficult, and there's a lot of code that i straight up just can't get to at this point) but you'd be surprised how much is just. sitting there in the assets, if you know where and how to look.

See, both games are built in Unity using a visual novel building library called Fungus. And what's interesting about Fungus is that all of the actual important information for the visual novel gameplay itself is stored in MonoBehavior object assets. If you were to asset mine the games, you'd notice that there's a LOT more in there than just sprites and textures. Take a look at this:

What you're seeing here are Fungus commands. All of them are JSON objects. Most of what I'm doing is looking at their contents.

The hard part, and what has taken me a lot of time studying and reverse engineering the code to figure out, is, number one, how to piece these objects back together to form dialogue trees. Because honestly, to use an analogy, what's pictured in that screenshot above there just amounts to loose leaf pages of a book scattered about. If you dump the assets and don't know what to do with them, it's not going to be much use to you.

Do you see those numbers on the side there, in the PathID column? Those are, to follow the analogy, page numbers. Essentially what I'm doing is putting the book back together.

But also, number two, I have to know how to actually read the information in the objects.

Here's a Menu choice command object from Last Legacy, Felix chapter 13. There's a lot of useful information here, but it might not make much sense if you don't know what you're looking at. But from just this I can see:

(obviously) the text displayed on this choice

Where this choice leads, by following the pathID of the target block

That this menu option is a "reversed" choice and that it has a medium choice weight

That it is interactable (i.e. not greyed out) and that this choice will not disappear if it's already been chosen and this menu is called again

among other things that usually aren't relevant.

Figuring out how to read these has been a combination of

reading through the publicly available source code for Fungus and seeing how it works

doing my best to decompile the C# scripts (for things that aren't part of the base Fungus library, such as upright/reversed choices)

and something very interesting... there's actually some .txt files that got left in the assets for fictif, presumably by accident, that are just. pseudocode for entire chapters of certain stories. there's only a handful, but comparing it to the actual code of those same chapters has helped me to decode a lot of it, which has helped me read other chapters for which no pseudocode txt files were left in.

You should see the long documentation I've written out for my own personal reference on how to read every single type of command object... it's a lot.

anyway. sorry this post got long. tl;dr i have way too much free time and love solving puzzles

Kaltrinkeda — A ToolBox e suas Funcionalidades.

Olá leitores, eu sou o Kirey e hoje trago mais uma Inovação do Kaltrinkeda:

O ToolBox ou Caixa de Utilidades é uma ferramenta que vem nativa em nossa IDE, e seu propósito é facilitar a rotina do programador com uma seleção de ferramentas nativas, otimizadas para produtividade para tornar essa experiência inesquecível

Não é necessário baixar nenhum pacote adicional para usá-lo.

O ToolBox pode ser acessado diretamente do Editor do seu projeto, basta clicar no botão e ele abre diretamente, com funções como:

Gerador de Lorem Ipsum

Gerador de UUID / GUID

Slugify Tool (transforma texto em slug para URLs)

Base64 Encoder/Decoder

Minificador de JSON, HTML, CSS, JS e Python

Conversor de Texto: maiúsculas, minúsculas, capitalize etc.

Markdown Preview (nativo em arquivos .md)

Editor HEX (pegue cores, tenha prévias, altere opacidade, gere paletas)

Diff Viewer (comparar dois textos)

Criptografia Simples: SHA-1 / SHA-256 / MD5 / Bash / AES-256

Conversores Numéricos: Binário ↔ Decimal ↔ Hex ↔ Octal

Timestamp ↔ Data (Unix Timestamp converter)

IMG Pogger (transforme Imagens em Base64)

IMG Hoster (permite hostear imagens no PostImg direto do app, útil para projetos HTML, transforme imagens em links)

Atalhos de teclado

Essas são algumas das funções na qual estamos trabalhando, mas a idéia é de que a ferramenta tenha centenas ou até milhares de ferramentas úteis, na ToolBox você pode buscar por palavras-chave e assim encontrar a ferramenta perfeita com mais facilidade.

Estamos avaliando cuidadosamente a implementação do ToolBox apenas por questões de desempenho, nossa proposta é oferecer um app funcional, independente da condição do usuário

Seja ele pobre, rico, intermediário, seu dispositivo deve suportar rodar a IDE em pelo menos 40 FPS estável, embora tenhamos toda uma Engenharia pra tornar o app otimizado, e mesmo com otimizações, reconhecemos que a performance pode variar em dispositivos mais limitados, podendo falhar.

Estamos abertos a idéias do público, você, caro leitor da NMBAH, oque você gostaria que sua IDE tivesse? Qual função seria maravilhosa de experienciar;

Entrar no seu projeto, estar no editor, clicar em 1 botão, e a ferramenta já estar pronta para uso. Conte pra gente nos comentários.

Nosso maior medo é lançar um aplicativo infuncional, temos compromisso com nossos usuários, e estamos prometendo um app funcional, diferente de outras IDEs de navegador que lagam, travam e são lentas

Preferimos arriscar não fazer do que entregar um produto ruim, isso inclusive ocorreu nessa postagem, o plano era demonstrar uma prévia da ToolBox, mas devido dificuldades técnicas, o design não atendeu as expectativas, portanto foi criada uma capa gráfica ao invés de mostrar o projeto.

Se essa função compromete a proposta do app, infelizmente não podemos implementar se não for possível otimizar para Todos.

A proposta da ToolBox é facilitar a vida do programador, como dito, as funções são pensadas propriamente para serem práticas, ela vem com múltiplas ferramentas que abrangem todas as linguagens

Você não precisa estar em um file de CSS para usar o Hex Editor, e pode usá-lo do Python ao MarkDown à vontade, essa caixa é um item Global, e se possível, poderá ser usado até mesmo no Console Pancreon.

Agradecemos a atenção de todos.

Tick Data × Stock API: The Precision Engine for High-Frequency Trading Strategies

In financial markets, every millisecond of delay can mean a difference of millions in profits. While traditional investors still rely on the "outlines" of candlestick charts, top traders have already combined tick data and stock APIs to build a "super-sensing capability" that captures the pulse of the market. This ability is not just about speed—it’s about transforming vast amounts of data into a precise decision-making engine. And at the core of this lies the perfect fusion of technology and tools.

Tick Data: Decoding the Market’s Microstructure

Tick data is the "atomic-level" record of financial markets, containing every transaction’s price, volume, timestamp, and trade direction. Unlike aggregated candlestick data, tick data preserves the market’s raw rhythm, enabling traders to:

Capture hidden liquidity shifts: Identify institutional actions like iceberg orders or large-order splitting through continuous tick data.

Anticipate short-term breakouts: Analyze tick distributions in high-volume zones to gauge the true strength of support/resistance levels.

Quantify market sentiment: Measure real-time shifts in bullish/bearish momentum based on tick direction ratios.

However, the value of tick data doesn’t reveal itself automatically—without an efficient toolchain, it becomes an overwhelming flood of information.

Stock API: Transforming Data into Strategy Fuel

The high-frequency nature of tick data imposes strict demands on technical infrastructure: even millisecond-level delays can cripple strategies, while data interruptions may trigger risk control failures. A professional stock API is the critical solution to these challenges:

1. Real-Time Performance: Syncing with the Market’s Heartbeat

Top-tier APIs ensure near-zero latency in delivering tick data from exchanges to strategy engines. For example:

WebSocket streaming replaces traditional HTTP polling to eliminate waiting gaps.

Multi-exchange parallel feeds prevent congestion in single data channels.

2. Flexibility: Custom Data Flows for Every Need

High-frequency strategies may require specific tick data types:

Raw ticks: Full transaction details for microstructure analysis.

Incremental updates: Only changed order book entries to reduce bandwidth load.

Smart aggregation: Time/volume-based pre-processing to lower system strain.

3. Stability: The Lifeline of High-Frequency Trading

API reliability directly determines strategy survival rates:

Auto-reconnect ensures uninterrupted data flow during network volatility.

Sequence validation timestamps prevent misaligned or lost packets from distorting signals.

Disaster recovery combines local caching with cloud backups to guarantee historical data integrity.

Case Studies: How Tick Data Powers Strategies

Strategy 1: Liquidity Arbitrage

Monitor cross-exchange price gaps via tick data. When large orders deplete liquidity on one platform, instantly execute counter-trades on another to capture convergence opportunities.

Strategy 2: Order Book Momentum

Analyze tick-level bid/ask imbalances—persistent large unfilled bids may signal imminent breakouts, triggering rapid position entries via API.

Strategy 3: Event-Driven Plays

During earnings announcements, API-captured tick anomalies reveal sentiment shifts hundreds of milliseconds ahead of news alerts, enabling preemptive positioning.

Why Alltick is the Ultimate Tick Data × API Solution?

Among data providers, Alltick stands out with three core advantages for high-frequency traders:

1. Speed Engine: Outpacing the Market

Understanding Authentication: Cookies, Sessions, and JWT

Understanding Authentication: Cookies, Sessions, and JWT

Authentication is a cornerstone of web security, ensuring that users can access only the resources they are authorized for. Different methods like cookies, sessions, and JSON Web Tokens (JWT) are commonly used to implement authentication. Here’s a breakdown of each method, their key features, and use cases.

1. Cookies

Cookies are small data files stored on a user’s browser and sent with every request to the server. They are often used to persist user authentication data across sessions.

Key Features:

Stored on the client side.

Can include attributes like HttpOnly, Secure, and SameSite to improve security.

Frequently used for tracking user sessions or preferences.

How It Works:

The server creates a cookie when the user logs in.

The cookie is sent to the user’s browser.

With every subsequent request, the browser sends the cookie back to the server.

Example (HTTP):http Set-Cookie: sessionId=abc123; HttpOnly; Secure; Path=/;

Use Case: Persistent login, especially for websites with session-based authentication.

2. Sessions

Sessions store user-specific data on the server. When a user logs in, the server creates a session and assigns a unique session ID. This ID is shared with the client, typically through a cookie.

Key Features:

Data is stored server-side, reducing the risk of client-side tampering.

Session data can include user-specific state, preferences, or permissions.

Requires server resources to manage.

How It Works:

User logs in, and the server creates a session.

A session ID is sent to the client (via a cookie or request).

The server retrieves session data using the session ID.

Example (Python Flask):python from flask import session# Set session data session['user_id'] = user.id# Get session data user_id = session.get('user_id')

Use Case: Suitable for server-rendered web applications requiring state management.

3. JSON Web Tokens (JWT)

JWTs are self-contained, compact tokens encoded in a URL-safe format. They consist of three parts: Header, Payload, and Signature. The payload often contains claims (e.g., user ID, roles, expiration time).

Key Features:

Stateless: No server-side storage needed.

Can be signed and optionally encrypted for security.

Suitable for distributed systems like microservices.

How It Works:

The server generates a JWT upon user login.

The JWT is sent to the client and stored (e.g., in local storage or cookies).

The client sends the JWT with each request (commonly in the Authorization header).

The server validates the JWT using its signature.

Example (Python):pythonimport jwt# Create a token payload = {"user_id": 123, "exp": 1672531199} secret = "my_secret_key" token = jwt.encode(payload, secret, algorithm="HS256")# Decode a token decoded = jwt.decode(token, secret, algorithms=["HS256"])

Use Case: Best for stateless authentication in APIs and microservices.

Choosing the Right Approach

MethodBest ForDrawbackCookiesPersistent client-side state managementVulnerable to client-side risksSessionsServer-side state managementScales with server resourcesJWTStateless, distributed systemsLarger token size

Conclusion

Cookies, sessions, and JWTs each have their strengths and trade-offs. The choice depends on your application’s architecture and requirements:

Cookies and sessions are ideal for traditional server-side web apps.

JWTs excel in stateless, distributed systems like APIs or microservices.

Understanding these mechanisms empowers you to design secure, scalable, and efficient authentication systems for your applications.

Improper Alignment due to default package setting

In a report generation software, with the option available “Export as PDF” the reports are exported in PDF formats that can be downloaded. Not quite, whenever the reports were exported to PDF formats, the PDF files lacked readability as there was an improper alignment issue.

When we looked into the improper alignment, we found the issues were due to the default settings of the PDFMake package content. The application collects contents from data centers and generates the PDF report.

We use an API call to invoke the data centres that responds with a . JSON format(encrypted) with a 64 — bit base. Only after the code’s been decoded, it employs the PDFMake Package 0.1.54 to generate the PDF report.

Still, we did not get an expected outcome. Moreover, the report could not be manually aligned. By default, the contents in the report were left aligned. While re checking it was found that the package did not employ the properties “preserveLeadingSpaces and preserveTrailingSpaces”.

After restarting the execution, the contents still lacked alignment. We identified this was because of the default font style “ROBOTO” that comes with the PDFMake Package. To overcome this, download and include the “LUCIDA CONSOLE” font style. Now we got a perfectly aligned readable PDF report.

In this blog we discuss Qwen, Qwen2.5, and Qwen2.5 Coder-32B, the cutting-edge AI tool designed to revolutionize programming efficiency, to reach your full development potential.

Introduction Of Qwen

What is Qwen?

Alibaba Cloud has separately built a set of large language models (LLMs) called Qwen. Qwen can provide services and support in a variety of domains and jobs by comprehending and analyzing natural language inputs.

Who made Qwen?

Qwen, created by Alibaba Cloud, advances artificial intelligence (AI) to new heights, making it more intelligent and practical for computer vision, voice comprehension, and natural language processing.

What are the parameters of the Qwen model?

There are four parameter sizes available for the original Qwen model: 1.8B, 7B, 14B, and 72B.

Qwen2 Introduction

Many developers have constructed additional models on top of the Qwen2 language models in the three months after Qwen2 was released, giving us insightful input. Throughout this time, it have concentrated on developing increasingly intelligent and sophisticated language models. To present Qwen2.5, the newest member of the Qwen family.

Dense, user-friendly, decoder-only language models that come in base and instruct variations and sizes of 0.5B, 1.5B, 3B, 7B, 14B, 32B, and 72B.

learned using our most recent large-scale dataset, which contains up to 18 trillion tokens.

notable gains in interpreting structured data (such as tables), producing structured outputs, particularly JSON, following instructions, and producing lengthy texts (more than 8K tokens).

more adaptable to the variety of system prompts, improving chatbot condition-setting and role-play implementation.

Context length is capable of producing up to 8K tokens and supporting up to 128K tokens.

The more than 29 languages supported include Chinese, English, French, Spanish, Portuguese, German, Italian, Russian, Japanese, Korean, Vietnamese, Thai, Arabic, and others.

kung pow penis is nothing. the pixel height of a post means nothing. the content inside matters, and if it's a wall of text that has to be decoded into json and rendered into readable text on screen and thats a lot of work to do

every time i see a big fuckin post that nearly crashes the app i remember when i was working on the iOS app at Tumblr i used the aphobe block list as a test case for crashing the app
