ElixirConf 2017 - Writing an Editor in Elixir - Ian Duggan
Writing An Editor In Elixir -- Elixir for GUIs? Yes, it’s possible. I’m working on a modern editor in Elixir, and I’ll show you how I’m doing it. Topics will include GUI libraries for Elixir, ports, NIFs, interfacing Elixir with other languages (especially Rust), and general design principles for a modern, programmable editor.

Why Design UI Tips
I’ve always had an off fascination with editors.
The answer, I believe, as to what makes a good editor, is when it makes us more productive. When it allows us to get into a flow. When it gets out of the way and just lets us create. I have a theory that, for some, it’s what makes you most productive quickly (TextMate, Sublime, Atom) For others, it is what you can control deeply (Emacs, Vi, Atom?). But if they are so hard to learn, why do they persist? Power... the power to control your environment (a true hacker wants to control everything... quote? reference?). But... why don’t people just add to Sublime/Atom/TextMate, etc... because of friction.
My hypothesis is that the reason Emacs is so powerful, is that you can write emacs in emacs without leaving it it can grow as you use it. Others can too, to some extent, but not to the deep level of customizability you can get from Emacs... Not even vim can do this (which is why Spacemacs exsists... some people want the keys of vi with the features of emacs)...
This editor had lisp embedded. It could read email and netnews before your cellphone could make phone calls without being attached to a car.
You could customize it, from the very beginning. DECADES AGO. New editors are adding most of its features, except for the ability to CODE ITSELF WHILE RUNNING.
Why is this a good idea?
1. Emacs <-> Vixen
2. C core, Elisp control <-> Rust core, Elixir control
3. Elisp <-> Elixir
4. Dynamic <-> Dynamic
5. Runtime eval <-> Runtime compile (hot code reload) 6. Macros <-> Macros
7. DSLs <-> DSLs
8. concurre-what? <-> concurrency
9. immuta-maybe? <-> immutable
10. beachballs <-> no beachballs (if designed well)
Rust stuff might mess up your schedulers, Elixir string manipulations might cause GC issues — you need to profile and make a choice. That said, this is an editor and we are using Elixir more for the flexibility than the performance...
Some issues around signals, detecting window size (in escripts) Use tty like iex (have user_drv open it), anoint self as shell
Very much like unix. A process has a process group. IO is sent to the process group session leader. erlang:display goes around this.
editor in control Rust/Termion ruby rust can launch w/out shell and insert ourselves as one can multiplex the shell in our own buffer pty/port-driver combo Telnet Port Driver
WTF is Twisted?
"WTF is Twisted? (or; owl amongst the ponies)" is a talk that introduces the Twisted asynchronous programming framework, how it works, and what uses it.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle.
Gopinath Rebala
Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.

Securing your Kubernetes cluster_ a step-by-step guide to success !
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

National Security Agency - NSA mobile device best practices
Threats to mobile devices are more prevalent and increasing in scope and complexity. Users of mobile devices desire to take full advantage of the features
available on those devices, but many of the features provide convenience and capability but sacrifice security. This best practices guide outlines steps the users can take to better protect personal devices and information.
PHP Frameworks: I want to break free (IPC Berlin 2024)
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
- These are slides of the talk given at IEEE International Conference on Software Testing Verification and Validation Workshop, ICSTW 2022.
