Hey, Tumblr, I'm angry and frustrated and I'm making it your problem.

Break the Keep Reading only if you either A. have any experience with OBS-Websocket or other such integrations, or B. sincerely wish to partake in my suffering. Warning for excessive cursing, it gets rough.

Update on the whole KT-1632 overlay situation: After a handful of minor technical difficulties and rookie mistakes (hey cat, it would help if you actually turned on the damn websocket before trying to connect to it), I've established a base framework for connecting to OBS Websocket.

Once I had that in place, I started testing out what kind of messages I can get, and uh... I'm already running into a huge problem, here.

See, OBS Websocket 5.0 has the following messages that seem pertinent to my use case: CurrentProgramSceneChanged, SceneTransitionStarted, SceneTransitionEnded, and SceneTransitionVideoEnded. Keep in mind, the only documentation I can access right now, as far as I can tell, is just the 5.0.1 OBS-Websocket.

Here's a refresher on the use case: I want to be able to move elements of my Unity-based stream overlay depending on which scene is currently active in OBS. A wrinkle in this is that I use a custom stinger transition with a specific cut point, like this:

Now, all three events regarding the scene transition only have one piece of data to them: the name of the transition (which is basically always going to be "SniperScope"). The only event that actually tells me what scene is being switched to is the CurrentProgramSceneChanged event.

There is an immediate problem.

Funnily enough, this order of operations is actually backwards from the current documentation:

On the one hand, there could potentially be some sort of delay or other issue involved with WebsocketSharp / Unity that's responsible for this, however in my testing the exact amount of delay and order of operations is entirely consistent every single time I initiate a transition in OBS. The first message almost always arrives instantaneously; it's the other three messages that seem to come whenever they feel like it, and not at all close to what they need to be at.

On the other hand-- wait, what? What's this issue on the official obs-websocket github about--

So you're telling me that SceneTransitionStarted used to have the from and to scenes specified in the event data in version 4, and they removed it in version 5 for literally no other reason than an RPC overhaul? And they haven't added it back in OVER A YEAR?!

Now, the github actually does have an install link for obs-websocket version 4.9.1-compat that should (keyword should, you know how that goes) work with OBS 29 (more specifically, it should work with 28+, which means there isn't even a guarantee for it to work with OBS 29... fucking awesome).

However, uhhhhhh... I cannot find ANY FUCKING DOCUMENTATION FOR 4.9'S PROTOCOL WHATSO-FUCKING-EVER. There is LITERALLY ONLY 5.0 in the readmes and protocol.md docs.

This shit has me pulling my hair. I'm goin' the fuck to sleep. Anyone got any bright fuckin ideas, I'm all fuckin' ears for it in the morning.

MEV Bot Development: A Step-by-Step Guide

Introduction

As the DeFi ecosystem grows more complex, MEV (Maximal Extractable Value) bots have become one of the most powerful—and controversial—tools in crypto trading. These bots are designed to extract value from blockchain transactions by reordering, inserting, or censoring transactions in a block. While originally focused on miners, today’s MEV bot development company opportunities are accessible to smart developers who can build bots to interact with protocols like Uniswap, SushiSwap, Curve, and others.

In this step-by-step guide, we’ll walk through the process of developing your own MEV bot—from understanding its core components to writing, simulating, and deploying it.

What Is an MEV Bot?

An MEV bot is an automated trading agent that exploits inefficiencies in blockchain transactions. It aims to maximize profit through techniques such as:

Arbitrage: Buying an asset at a lower price on one DEX and selling it higher on another.

Sandwich Attacks: Placing a buy order before and a sell order after a large user transaction to manipulate price movements.

Liquidation Sniping: Monitoring DeFi lending protocols for vulnerable positions and profiting from liquidations.

These bots monitor the mempool or integrate with services like Flashbots to submit private bundles directly to miners or validators.

MEV Bot Development: A Step-by-Step Guide

Step 1: Understand MEV Fundamentals

Start by learning what Maximal Extractable Value (MEV) means, how it impacts Ethereum and other blockchains, and the types of MEV strategies such as arbitrage, sandwich attacks, and liquidations. Understanding blockchain mechanics, mempool structure, transaction ordering, and frontrunning concepts is critical before development.

Step 2: Choose Your MEV Strategy

Select the specific MEV technique you want to implement—DEX arbitrage, sandwiching, liquidation sniping, or time-bandit attacks. Your choice will determine the logic and external data your bot will need to operate effectively.

Step 3: Set Up Your Development Environment

Install essential tools like Node.js, Hardhat or Foundry, ethers.js or web3.js, and connect to Ethereum mainnet via Infura or Alchemy. Set up Flashbots for private transaction bundling. Use Git and VSCode for development and version control.

Step 4: Monitor Blockchain Data and Mempool

Develop or use an existing script to monitor pending transactions in the mempool using WebSocket or JSON-RPC. For strategies like sandwich or liquidation attacks, listen for large swaps or vulnerable loans, and simulate how your bot should respond.

Step 5: Write the Bot Logic

Create the logic for transaction construction, execution flow, and profit calculation. Include logic for gas estimation, token approvals, smart contract calls, and condition-based execution. Integrate error handling and fallback mechanisms.

Step 6: Simulate and Test on a Forked Network

Use Hardhat or Foundry to fork mainnet and simulate your bot’s transactions in a safe environment. Test for profitability, failed conditions, slippage, and gas efficiency. Refine strategy logic based on simulation results.

Step 7: Integrate Flashbots for Private Execution

To avoid frontrunning and reduce failed transactions, integrate with Flashbots by creating and submitting bundles directly to miners or validators. This helps ensure your transactions are mined in the intended order.

Step 8: Deploy the Bot on Mainnet

Once tested, deploy the bot on the Ethereum mainnet or another supported network. Run it on a secure server or cloud platform. Use cron jobs or real-time triggers to keep the bot active and responsive.

Step 9: Monitor and Optimize Performance

Track your bot’s trade history, gas usage, and success rate. Use dashboards or logging tools for performance monitoring. Continuously optimize strategies by adapting to network changes, gas spikes, and competition from other bots.

Step 10: Stay Updated and Compliant

The MEV landscape evolves quickly. Stay informed through forums, GitHub, and Flashbots research. Monitor ethical debates and legal implications around MEV activities. Consider evolving your bot for multi-chain or L2 MEV opportunities.

What Makes MEV Bots Different from Regular Crypto Bots?

MEV bots differ from regular crypto trading bots in that they extract profits by manipulating the order and timing of on-chain transactions, rather than relying on market trends or exchange arbitrage. While regular bots operate through APIs or smart contracts to execute predefined strategies like scalping or grid trading, MEV bots actively monitor the blockchain’s mempool to exploit inefficiencies such as frontrunning, sandwich attacks, and liquidations. They often use private relayers like Flashbots to submit transaction bundles directly to validators, enabling faster and more secure execution. This makes MEV bots more complex, time-sensitive, and ethically debated compared to traditional trading bots.

Conclusion

A MEV bot development can be highly profitable—but it’s also complex, competitive, and ethically gray. With the right technical knowledge, tools, and strategic insights, developers can enter the world of MEV extraction and participate in the most cutting-edge space in DeFi.

Whether you're building a simple arbitrage bot or a sophisticated front-runner, understanding the Ethereum transaction stack and using Flashbots responsibly is key to long-term success.

What is WebRTC (Real-Time Peer-to-Peer Communication)?

In a world that thrives on real-time digital communication, WebRTC (Web Real-Time Communication) has emerged as one of the most innovative technologies, enabling seamless peer-to-peer communication directly in web browsers. Whether you’re making a video call, joining a conference meeting, or chatting live on a support portal, chances are you’re benefiting from WebRTC’s powerful capabilities — often without even realizing it.

Understanding WebRTC

WebRTC is an open-source project developed by Google that allows direct peer-to-peer communication via audio, video, and data sharing without the need for plugins or third-party software. It is built into most modern browsers, including Chrome, Firefox, Safari, and Edge, making it easily accessible to developers and users alike.

The primary goal of WebRTC is to establish real-time, low-latency connections between users. This is achieved using a set of standardized APIs that allow devices to discover one another, negotiate communication parameters, and exchange encrypted data streams — all within the browser.

How WebRTC Works

To appreciate the power of WebRTC, it’s helpful to understand the basic flow of how it works:

Signaling: Before a connection is established, WebRTC needs a signaling mechanism (not defined by WebRTC itself) to exchange metadata like network information and media capabilities. This is usually done through WebSocket or HTTP.

ICE Framework: WebRTC uses ICE (Interactive Connectivity Establishment) to discover the best path between devices by testing a series of connection candidates.

STUN/TURN Servers: These servers help navigate NATs (Network Address Translators) and firewalls. STUN servers find the public IP address, while TURN servers relay data if a direct connection can’t be established.

Media and Data Channels: Once the connection is made, WebRTC enables the real-time exchange of media (audio/video) or generic data through secure channels.

Key Features of WebRTC

Plugin-Free Communication: Unlike traditional VoIP or video services, WebRTC does not require any software installation or browser plugins.

Cross-Platform Compatibility: Works on all major desktop and mobile browsers.

Security: Encrypted media and data using DTLS and SRTP protocols.

Low Latency: Ensures real-time communication suitable for video conferencing, gaming, or live support.

Data Channels: Beyond voice and video, WebRTC allows the exchange of files or text data securely.

WebRTC Use Cases

1. Video Conferencing

Services like Google Meet and Facebook Messenger use WebRTC to provide smooth video calling experiences. It supports group calls, screen sharing, and adaptive streaming.

2. Customer Support Chat

Many businesses integrate WebRTC to enable real-time chat and call support directly within their websites — no downloads required.

3. Telehealth Services

Doctors can securely consult patients using video calls facilitated by WebRTC, helping extend healthcare access remotely.

4. Online Gaming and Collaboration Tools

Real-time voice chat and data sharing enhance the gaming experience, while collaboration tools like whiteboards and co-editing apps use WebRTC to maintain instant updates.

5. Affordable International Calling

Companies leveraging WebRTC can offer competitive calling services. For example, they enable users who are Ready to Make Affordable International Calls right from a browser window, bypassing traditional telecom infrastructure.

Why WebRTC Matters in Today’s Digital World

The global shift to remote work, online learning, and virtual socializing has amplified the need for reliable, real-time communication. Traditional systems like PSTN (Public Switched Telephone Network) or even some VoIP protocols often involve complex setups or subscription models. WebRTC breaks down those barriers by being free, efficient, and developer-friendly.

Furthermore, by enabling international calling directly from browser, WebRTC removes the friction often associated with downloading software or using hardware-based phones. This is especially advantageous for people in regions with limited access to traditional telephony or for companies looking to serve global audiences efficiently.

WebRTC and the Telecom Industry

The telecom landscape is evolving. Once dominated by landlines and cellular services, the focus is shifting toward digital-first solutions. WebRTC plays a crucial role in this transformation, allowing providers to offer more flexible and cost-effective communication services.

For example, users can now Call landlines and mobiles anywhere in the world through web-based platforms powered by WebRTC. This innovation not only simplifies international communication but also drastically reduces the associated costs.

Startups and enterprises alike are incorporating WebRTC into their offerings to disrupt traditional calling plans. By doing so, they empower individuals and businesses to be Ready to Make Affordable International Calls — whether for personal use, customer support, or business meetings.

Challenges and Limitations

While WebRTC is powerful, it’s not without challenges:

Browser Compatibility: Although support is widespread, there are still minor differences in how browsers implement WebRTC.

Network Reliability: Performance can be affected by poor internet connections, especially during high-bandwidth activities like HD video calls.

Scalability: Peer-to-peer connections are optimal for small groups. For large-scale broadcasts, you need additional infrastructure like SFUs (Selective Forwarding Units).

Security and Privacy: Even though WebRTC uses strong encryption, developers must still follow best practices to ensure user data is protected.

Future of WebRTC

As the demand for real-time communication grows, so will the capabilities of WebRTC. New updates aim to improve codec efficiency, integrate with machine learning tools (e.g., for noise suppression or auto-captioning), and enhance support for multi-party calls.

With the increasing integration of 5G and edge computing, WebRTC is poised to deliver even more responsive and immersive communication experiences across devices and platforms.

WebRTC represents a paradigm shift in how we communicate online. From casual video chats to enterprise-grade conferencing systems, it enables efficient, scalable, and secure real-time communication across the web. Whether you’re looking to chat face-to-face, collaborate on projects, or are Ready to Make Affordable International Calls, WebRTC is the technology powering these seamless experiences.

As digital transformation continues to unfold across industries, WebRTC will remain a foundational element, enabling users to Call landlines and mobiles anywhere in the world with just a click — no downloads, no delays, just real-time connection.

For PierMesh, how would you envision something like file sharing/hosting working? Would it be like how it is now, with someone setting up some dedicated host and others being able to access/replicate it like current file sharing server/torrenting setups?

Sorry I just saw this!

So small file sharing directly over PierMesh will be delivered directly to the recipient on the backend with LoRa and the frontend with Websockets with the caveat that it does have to pass through a node physically. We already have a peer to peer protocol called Bubble which will handle this and I'm working on e2ee at the moment so data can be securely shared. As an intermediate step for larger files though we'll also have a way to do peer to peer sharing over the current main internet.

Addition: for the scenario that someone wants to advertise a file for download (like serving it in traditional architecture) in some way that will need to be implemented but is trivial given the architecture of PierMesh.

Breaking Barriers in Software Quality: Advanced API Testing Services for Modern Architectures

In the dynamic landscape of software engineering, application performance, scalability, and reliability have become non-negotiables. With the shift from monolithic architectures to microservices, and the explosion of interconnected systems, APIs are now the backbone of modern digital ecosystems. As APIs grow in complexity and ubiquity, so too must the strategies used to test them.

At Robotico Digital, we understand that software quality hinges on much more than clean UI and functional frontends. It’s about what lies beneath — how systems interact, how services communicate, and how fast and securely data flows between components. This is where our API Testing Services break barriers, ensuring quality at the very core of your application stack.

Understanding API Testing in the Context of Modern Architectures

API Testing refers to the process of validating application programming interfaces (APIs) directly at the message layer, without the use of a GUI. It verifies that APIs return correct responses, handle errors appropriately, and meet performance and security expectations.

In microservices, APIs are the only communication mechanism between services. In serverless computing, APIs trigger the logic. And in mobile-first or headless applications, APIs drive every interaction.

Thus, API Testing Services today must adapt to modern environments by:

l Supporting asynchronous data flow and event-driven models.

l Validating REST, SOAP, GraphQL, gRPC, and WebSocket protocols.

l Integrating with CI/CD pipelines and DevOps tools for rapid iteration.

Why Traditional Testing Fails Modern Architectures

Legacy testing models often fall short because:

l They rely heavily on UI testing, which isn’t scalable or robust.

l They fail to isolate service-level issues in microservice deployments.

l They lack integration with agile development and DevOps cycles.

At Robotico Digital, we address these challenges with a future-ready API-first testing strategy that enables rapid development and secure, stable deployments.

We use data-driven test design and test parallelism to achieve high throughput and full API coverage — even across large microservices ecosystems.

Intelligent Test Data Management (TDM)

Test data is critical, especially when APIs depend on complex backend states. Our TDM solutions provide:

l Synthetic test data generation using Faker and Mockaroo

l Encrypted data masking for secure production cloning

l Environment-specific data pools to avoid cross-test pollution

This empowers our teams to run API tests with production-like reliability in test environments.

Performance & Load Testing of APIs

APIs underperforming in production can lead to latency, downtime, and failed transactions. Robotico Digital performs rigorous API performance testing, including:

Load Simulation with tools like JMeter, Gatling, and Locust

l Spike, soak, and stress testing to evaluate limits

l Latency monitoring across geographies

l Response time threshold validations

Our tests replicate thousands of concurrent requests, ensuring your APIs hold up under real-world traffic scenarios.

API Security Testing: Guarding the Gateway

Since APIs often expose business logic and sensitive data, security testing is non-negotiable. Robotico Digital incorporates security scanning into API Testing Services by:

l Validating for OWASP API Top 10 vulnerabilities

l Testing for broken authentication, excessive data exposure, rate limiting, and injection attacks

l Integrating Burp Suite, OWASP ZAP, and custom security probes into test pipelines

We don’t just test functionality — we test for resilience against malicious attacks.

Real-Time Reporting and Analytics

Transparency is critical. Our reporting dashboard includes:

l Detailed test summaries with pass/fail ratios

l Latency graphs and time-to-first-byte analysis

l Defect tracking with Jira, Azure Boards, or custom integrations

l REST APIs to extract test data into BI tools or custom reports

Clients always have clear visibility into the testing progress and quality metrics.

Future-Forward Testing with AI & ML

Robotico Digital is investing in the next generation of API Testing with:

l AI-based anomaly detection using test execution logs

l Predictive analytics to identify flaky endpoints

l Self-healing scripts that auto-adjust to changes in API structures

l NLP-driven test generation for conversational interfaces and AI-driven apps

These features ensure our API Testing Services evolve alongside tomorrow’s tech stacks.

Alltick API: Real-Time Data Solutions from Quantitative Trading Primer to Professional Strategies
