The document provides an overview of Clojure and lists several popular Clojure frameworks.
EhTrace -- RoP Hooks
This document describes EhTrace, a tool for tracing the execution of binary programs through hooking and branch stepping. EhTrace uses the Windows VEH exception handler to single step programs by setting flags in the CPU context. It can be used to analyze program control flow at the basic block level for purposes like malware analysis, debugging, and code coverage. The document discusses techniques for maintaining control during tracing and fighting attempts by the target program to detect or alter the tracing.
State Of Zope Linuxtag 2008
The document summarizes the past, present, and future of the Zope project. It discusses how Zope was initially successful competing with other web frameworks but then lost popularity with the rise of Ruby on Rails and other Python frameworks. This led to an identity crisis within the Zope community. The vision going forward is to phase out the term "Zope 3", support Zope 2 as the application server, and promote GROK and Zope components as lower barrier ways to build with Zope.

Polymer in the real life - Devoxx France - 2016 04-20
In the last two years I've been speaking a lot about web components and Polymer in conferences and user-groups, sharing a vision of the upcoming web-component revolution. But after these introductory talks I often got the same question: "that seems great... but does it works in Real Life?" Ah, the pesky real life question...
In this talk I'm going to tackle that question in the best way I know: I'm going to tell you my experience of almost two full years web applications with Polymer in the real life, for real projects in a real enterprise with real costumers, and all the lessons I've learnt from it.
You will heard why did I choose Polymer, how I dealt with the 0.x versions lifecycle, the good points and the bad ones too, how I did integrate lots of 3rd part libs into a component architecture and how now I'm able to create full fledge Progressive Web Apps using Polymer in a simple way without having to deal with the complexity of Angular/React/Whatever JS, but also how to integrate your components into those frameworks if needed.

How could I automate log gathering in the distributed system
This document discusses how the author automated log gathering in a distributed system using Perl. As a new developer on a large networking project, the author faced challenges in manually collecting logs from many boards to debug issues. The author developed a solution using the Expect Perl module to remotely login to each board, retrieve logs, and run commands. This allowed logs to be gathered automatically in minutes rather than the hours it took manually. The author's solution saved significant time and was used until more formal reporting tools were created.

Powering Tensorflow with big data using Apache Beam, Flink, and Spark - OSCON...
TensorFlow is all kinds of fancy, from helping startups raising their series A in Silicon Valley to detecting if something is a cat. However, when things start to get “real,” you may find yourself no longer just dealing with mnist.csv but instead needing do large-scale data prep as well as training.
Holden Karau details how to use TensorFlow in conjunction with Apache Spark, Flink, and Beam to create a full machine learning pipeline—including the annoying feature engineering and data prep components that we like to pretend don’t exist. Holden also explains why these feature prep stages need to be integrated into the serving layer. She concludes by examining changing industry trends, like Apache Arrow, and how they impact cross-language development for things like deep learning. Even if you’re not trying to raise a round of funding in Silicon Valley, this talk will give you tools to do interesting machine learning problems at scale.
Introduction to Binary Exploitation
This document provides an introduction to binary exploitation. It outlines the course, which will cover basic stack overflows, shellcode injection, and exploit mitigation technologies. It explains how buffer overflows can be used to overwrite the return address and change the flow of execution. By injecting shellcode into the buffer and overwriting the return address to point to it, arbitrary code can be executed to gain unauthorized access. Modern defenses like ASLR and NX are discussed, as well as future topics like return-oriented programming and format string vulnerabilities. The overall goal is to understand software exploitation and how to identify vulnerabilities in programs.
TFLite NNAPI and GPU Delegates
TensorFlow is the most popular machine learning framework nowadays. TensorFlow Lite (TFLite), open sourced in late 2017, is TensorFlow’s runtime designed for mobile devices, esp. Android cell phones. TFLite is getting more and more mature. One the most interesting new components introduced recently are its GPU delegate and new NNAPI delegate. The GPU delegate uses Open GL ES compute shader on Android platforms and Metal shade on iOS devices. The original NNAPI delegate is an all-or-nothing design (if one of the ops in the compute graph is not supported by NNAPI, the whole graph is not delegated). The new one is a per-op design. When an op in a graph is not supported by NNAPI, the op is automatically fell back to the CPU runtime. I’ll have a quick review TFLite and its interpreter, then walk the audience through example usage of the two delegates and important source code of them.
The future of templating and frameworks
This document discusses the future of templating frameworks and introduces lit-html as a new lightweight templating solution. Lit-html uses tagged template literals to parse templates and returns templating instructions to efficiently update the DOM. It works well with web components for building reusable custom elements. LitElement provides a base class to simplify building components with lit-html. Element router provides routing capabilities for web components. Overall, lit-html and related tools provide a performant and flexible approach to templating within the web components standard.
Continuous Go Profiling & Observability
This presentation is for Go developers and operators of Go applications who are interested in reducing costs and latency, or debugging problems such as memory leaks, infinite loops, performance regressions, etc. of such applications. We'll start with a brief description of the unique aspects of the Go runtime, and then take a look at the builtin profilers as well as Go's execution tracer. Additionally we'll look at the interoperability with popular observability tools such as Linux perf and bpftrace. After this presentation you should have a good idea of the various tools you can use, and which ones might be the most useful to you in a production environment.

PHARO IoT: Installation Improvements and Continuous Integration
1. The document discusses improvements made to the installation process and continuous integration of Pharo IoT.
2. Previously, installing Pharo IoT manually took many steps and was difficult for newcomers. The process has been simplified to take less than 10 minutes with pre-packaged files.
3. Continuous integration was added using Travis CI to automatically build documentation, load libraries, and release packaged files with each code change. This makes the process transparent and easy to contribute to.
Pharo IoT Installation Improvements and Continuous Integration

Putting Compilers to Work
Compilers can have a huge effect on software efficiency and performance by changing what user experiences are possible and reducing CPU and resource usage. They work by parsing code, generating machine-friendly representations, and emitting optimized machine code. As web programming grew in complexity, developers started building more efficient compilers for dynamic languages to preserve rapid development workflows while improving performance. There are various approaches to building compilers like interpreters, transpilers, using backends like LLVM, and fully custom solutions. The best approach depends on goals, constraints, and tradeoffs around control, performance, and development effort. Optimization focuses should include memory usage, caching, and runtime layout. Future areas may include database query compilation for real-time analytics on large datasets.

Roo uses AspectJ to actively generate code based on annotations and allows customization through add-ons. The document demonstrates Roo's features and explains how applications can later remove their dependency on Roo through refactoring.
Intro To AOP
The document introduces aspect-oriented programming (AOP), which aims to increase modularity by allowing separation of cross-cutting concerns. It is not a programming language, solution to all problems, or replacement for object-oriented programming, but rather a programming pattern and tool. Aspects in AOP can exist encapsulated and be attached to code constructs. Cross-cutting concerns are aspects of a program that affect other concerns and are difficult to separate cleanly. AOP uses interception or IL weaving to inject execution of concerns. The document discusses AOP styles, constructs, tools, arguments against it, and considerations for new and existing projects.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

Digital Banking in the Cloud: How Citizens Bank Unlocked Their Mainframe
Inconsistent user experience and siloed data, high costs, and changing customer expectations – Citizens Bank was experiencing these challenges while it was attempting to deliver a superior digital banking experience for its clients. Its core banking applications run on the mainframe and Citizens was using legacy utilities to get the critical mainframe data to feed customer-facing channels, like call centers, web, and mobile. Ultimately, this led to higher operating costs (MIPS), delayed response times, and longer time to market.
Ever-changing customer expectations demand more modern digital experiences, and the bank needed to find a solution that could provide real-time data to its customer channels with low latency and operating costs. Join this session to learn how Citizens is leveraging Precisely to replicate mainframe data to its customer channels and deliver on their “modern digital bank” experiences.

The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.
GNSS spoofing via SDR (Criptored Talks 2024)

- 12. Does it work ? • It can boot Erlang/OTP to the Eshell (ej command). • There's a GUI console (ejc command) which supports ^G and line edi0ng. The console s0ll needs some work [Swing wizards welcome here]. • Run Erlang distribu0on, tcp/ip, port commands (stdio to external processes). • You can run the compiler (c(foo) command in the prompt) • It runs mnesia with distribu0on across Erjang/BEAM nodes. • The HTTP packet parsers are in the tcp/ip stack, so mochiweb and webmachine can run (without crypto for now). • Larger systems like rabbitmq and riak can boot; and works for basic cases ... but it's not ready for prime 0me yet. • Etc. etc. Lot's of stuff work.
- 13. BUT!!! • A few BEAM instruc0on are missing some run0me support. • There are also BIFs missing, or only par0ally implemented; we're quite careful to throw @erjang.NotImplemented@ in BIFs (or branches thereof) which are not complete. • Many OTP modules need NIFs or linked-‐in drivers that are en0rely missing or only partly implemented.
