Bitcoin: History and Use Cases
Monday September 16, 2024 12:30 - 13:30 MDT
Spruce 3/4
Jon will share the Bitcoin “origin story,” which is the story of the Cypherpunks and the solution to the Byzantine Generals Problem. He will discuss several real-world problems that the Cypherpunks solved using cryptography, leading up to the development of Bitcoin.

Jon will also cover the three most important use cases of the Bitcoin protocol. The first two use cases, Store of Value and Medium of Exchange, are well-known, but have other, non-Bitcoin solutions. The third use case, Native Internet Money, has a unique solution of great interest to software engineers, particularly in the age of AI.

–

In Eduardo Madrid’s presentation, Bitcoin: From the White Paper to the World's Reserve Currency, scheduled for Tuesday, he will outline the implementation of the Bitcoin protocol based on the Bitcoin White Paper, focusing on how programmable money is possible.

In Kris Jusiak’s presentation, Bitcoin Script: Implementation Details and Use Cases, scheduled for Wednesday, he will present the details which make programmable money possible.

In Eduardo Madrid’s presentation, Role Playing Bitcoin Protocols Including the Lightning Network, scheduled for Thursday, with just an intuitive understanding of Bitcoin Script he will describe the higher abstraction level protocols, such as the Lightning Network.

Join us on Friday for a panel in which Eduardo, Jon, and Kris will answer Bitcoin questions

The Power of Reducing Variable Scope
Monday September 16, 2024 12:30 - 13:30 MDT
Cottonwood 2/3
Perhaps you've heard that you should reduce variable scope. But have you ever really stopped to think about why? In this session we'll run through a manufactured example that illustrates the difference reducing variable scope can make, and we'll do some examination as to what difference it made with the compiler.

"Pick a random number... no, not that one!" - Tales of Real-World Exploits Based on Bad Randomness
Monday September 16, 2024 20:30 - 21:30 MDT
Cottonwood 2/3
When it comes to security, using "good" randomness is key - at least so we are told. But unlike using an insecure protocol or a weak cryptographic key, it may not be intuitive why "bad" randomness may be a problem. What even makes randomness "good" or "bad"?

In this session we will explore several real-world exploits based on bad randomness including online poker, cryptocurrencies, cars, web-traffic encryption, and video games.
Don't worry, no security background knowledge needed.

In the end, you will have entertaining stories to share and a better and more intuitive understanding of the dangers of "bad" randomness.

Another Grab-bag of Oddments
Tuesday September 17, 2024 12:30 - 13:30 MDT
Maple 3/4/5
Play is FUNdamental. This session looks at some more odd corners of C++ where we try to do out-of-the-ordinary things just to see what's possible. Should we do these things in production code? Maybe not today, but in the future, who knows? 20-odd years of C++ has taught me that it's a hop and a skip from "ugh, that's really nasty" to "that's an established technique now".

Whatever you think of the things in this presentation, it's fun to learn. And things which we don't use in code today are still useful to know about when they crop up.

Bitcoin: From the White Paper to the World's Reserve Currency
Tuesday September 17, 2024 12:30 - 13:30 MDT
Spruce 3/4
Software engineers have an astounding opportunity to benefit from programmable money: now we can program directly with value, introducing the objectivity, auditability, and neutrality of Open Source Code, instead of the opaqueness, ambiguities, biases, and other issues of conventional monetary processes.

Bitcoin is arguably the simplest of all cryptocurrencies, giving us a real opportunity to learn it at this conference. We’ll show examples of money programmability to demonstrate what is truly possible…

In this session, we will leverage our skill as programmers by describing Bitcoin's design as a Software Engineering project, using the white paper as the primary source material with the updates running today ("SegWit", "Taproot", Schnorr Signatures…), aiming to acquire an intuitive understanding of its programming language, Bitcoin Script. Wednesday, you’ll have the opportunity to see the details of Bitcoin Script at Kris Jusiak’s presentation, and on Thursday, we’ll discuss higher abstraction level protocols such as Lightning.

Improving your Team(work)
Wednesday September 18, 2024 12:30 - 13:30 MDT
Spruce 3/4
As C++ developers, we will have the opportunity to work on many different teams and many different projects throughout our careers. We may sometimes work on a team that’s enjoyable, but isn't delivering too much. Other times, we might work on a team that delivers, but is no fun. If we’re really unlucky, we can end up on a team that doesn’t deliver and isn’t enjoyable. But occasionally, we can have the privilege of being part of a team that not only delivers, but is also a great team to be on.

The ability of us, as individual contributors within a team, to work together effectively is critically important. Often more so in C++ than in many other languages, due to the scale and complexity of the solutions we are often trying to deliver. This ability of individual contributors to work together collaboratively as a team is often not related to their C++ skills and knowledge.

This talk will explore the different characteristics of software development teams, and will look at the different roles and responsibilities within a team. Taking an evidence-based approach, we’ll consider what makes a good team, explore how to encourage more cooperative teamwork in order to achieve better results for everyone on the team, as well as offer some ideas for how to gently improve the teams on which we are currently working.

xstd::any - A New Container for Any Type with Extra Features and Small Object Optimization
Wednesday September 18, 2024 12:30 - 13:30 MDT
Cottonwood 2/3
Introducing xstd::any<N, Features...>, an extension of C++17’s std::any, designed to be a type-safe, owning container that can handle any data type with enhanced functionality. xstd::any can be configured with additional features such as comparability, hashability, and streamability, making it ready for use in std::map, std::unordered_map, and for output operations. This template-based implementation utilizes small object optimization to store types smaller than N bytes directly, avoiding heap allocation and minimizing dynamic memory overhead.
The presentation will explore the internal design and implementation of xstd::any<>, focusing on how it manages memory efficiently and maintains value semantics even when dynamically allocating larger objects. The session will showcase practical use cases, demonstrate usage with standard C++ containers, and explore the recent C++ features that enhance its functionality.
Like std::variant or std::tuple, xstd::any requires mechanisms to handle various contained object types seamlessly. We will discuss the addition of stream operators, hash functionality, and comparison operators, enhancing its usability across different programming scenarios.

Outline:
* Requirements: Understanding the needs for a versatile container like xstd::any, compared to other generic container types.
* Example Use Cases: Demonstrating practical applications and benefits.
Implementation and Memory Layout: Deep dive into technical details and optimizations.
* Testing: Approaches to ensure reliability and performance.
* Exception Safety: Handling errors and exceptions.
* Interaction with std:: Containers: Integration strategies and examples.
* Question & Answers: Open floor for audience queries and discussions.

Presentation Materials & Source Code: All resources, including detailed presentation slides and the source code, are freely available on GitHub for further exploration and testing.

Bitcoin: Role Playing Bitcoin Based Protocols Including the Lightning Network
Thursday September 19, 2024 12:30 - 13:30 MDT
Cottonwood 2/3
With an intuitive understanding of Bitcoin’s programmability we can study programming primitives such as “time” and “hash-time” lock contracts (HTLCs), which are the crucial building blocks for higher abstraction protocols such as the Lightning Network.

We will describe “Lightning” by role playing the actions of its nodes. We’ll see how they exchange value globally and nearly instantaneously. We’ll appreciate that this is a practical solution to the problem of micropayments, financial inclusion, and the starting point for even higher abstraction level protocols such as the Sphinx protocol. This protocol enables payments for streaming services without subscriptions or doxxing yourself.

Depending on audience interest, we’ll explore topics such as pay joins, coin joins, and/or how to incorporate into smart contracts real world data, using the primitive of Discrete Log Contracts (DLCs) to make so-called “Oracles.”

As we summarize these technical solutions, we’ll see that they create an ecosystem that leads to Bitcoin becoming the world’s reserve currency.
