    The OWASP ZAP core project

    The OWASP Zed Attack Proxy (ZAP) is one of the world’s most popular free security tools and is actively maintained by a dedicated international team of volunteers. It can help you automatically find security vulnerabilities in your web applications while you are developing and testing your applications. It's also a great tool for experienced pentesters to use for manual security testing. ZAP is an easy to use integrated penetration testing tool for finding vulnerabilities in web applications. It is designed to be used by people with a wide range of security experience and as such is ideal for developers and functional testers who are new to penetration testing. ZAP provides automated scanners as well as a set of tools that allow you to find security vulnerabilities manually. It stands between the tester’s browser and the web application so that it can intercept and inspect messages sent between browser and web application.

    PICSimLab - Prog. IC Simulator Lab.

    PICSimLab - Prog. IC Simulator Lab.

    PICSimLab is a realtime emulator for PIC, Arduino, STM32, ESP32, ...

    PICSimLab is a realtime emulator of development boards with MPLABX/avr-gdb debugger integration. PICSimLab supports microcontrollers from picsim, simavr, uCsim, qemu-stm32, qemu-esp32, and gpsim. PICSimLab has integration with MPLABX/Arduino IDE for programming the microcontroller's boards. As the purpose of PICSimLab is to emulate real hardware it does not have any source code editing support. For code editing and debugging the same tools used for a real board should be used with PICSimLab, such as MPLABX, Arduino IDE, or VSCode with PlatformIO. PICSimLab supports several devices (spare parts) that can be connected to the boards for simulation. Such as example LEDs and push buttons for simple outputs and inputs and some more complex ones like the ethernet shield w5500 for internet connection or the color graphic display ili9340 with touchscreen. The complete list of parts can be accessed in the documentation. Documentation at https://lcgamboa.github.io/picsimlab_docs/stable/

    PerfView

    PerfView

    PerfView is a CPU and memory performance-analysis tool

    PerfView is a free performance analysis tool that helps isolate CPU and memory-related performance issues. It is a Windows tool, but it also has some support for analyzing data collected on Linux machines. It works for a wide variety of scenarios, but has a number of special features for investigating performance issues in code written for the .NET runtime. If you are unfamiliar with PerfView, there are PerfView video tutorials. Also, Vance Morrison's blog gives an overview and getting started information. PerfView is built on a library called Microsoft.Diagnostics.Tracing.TraceEvent, which knows how to both collect and parse Event Tracing for Windows (ETW) data. Thus if there is any information that PerfView collects and processes that you would like to manipulate yourself programmatically, you would probably be interested in the TraceEvent Library Documentation.

    Selenium IDE

    Selenium IDE

    Open Source record and playback test automation for the web

    Open source record and playback test automation for the web. Simple, turn-key solution to quickly author reliable end-to-end tests. Works out of the box for any web app. Enjoy easier test debugging with rich IDE features like setting breakpoints and pausing on exceptions. Run your tests on any browser/OS combination in parallel using the Command-line Runner for Selenium IDE. Getting started with Selenium IDE requires no additional setup other than installing the extension on your browser. One of our driving philosophies is to provide an easy-to-use tool that will give instant feedback. We believe that the easier we can make it, the more likely people are to author tests, which in turn results in better-tested apps. Selenium IDE records multiple locators for each element it interacts with. If one locator fails during playback, the others will be tried until one is successful.

You can dispatch actions like a government-run mind control experiment, hot swap your app's state using Redux or mobx-state-tree, track your sagas, show image overlay in React Native, track your Async Storage in React Native, etc. You plug it into your app as a dev dependency so it adds nothing to your product builds. Reactotron, as an open source project, is free to use and always will be.

    ESP8266 Deauther Version 2

    ESP8266 Deauther Version 2

    Affordable WiFi hacking platform for testing and learning

    Scan for WiFi devices, block selected connections, create dozens of networks and confuse WiFi scanners! Version 3 is in development. It is stable to use, but it is very different. It is command-line based, which allows it to offer not just more features, but make them more customizable. This software allows you to easily perform a variety of actions to test 802.11 wireless networks by using an inexpensive ESP8266 WiFi SoC (System On A Chip). The main feature, the deauthentication attack, is used to disconnect devices from their WiFi network. No one seems to care about this huge vulnerability in the official 802.11 WiFi standard, so I took action and enabled everyone who has less than 10 USD to spare to recreate this project. I hope it raises more attention on the issue. In 2009 the WiFi Alliance actually fixed the problem (see 802.11w), but only a few companies implemented it into their devices and software.

It was created for Python programs but it can package and distribute software for any language. Conda as a package manager helps you find and install packages. If you need a package that requires a different version of Python, you do not need to switch to a different environment manager because conda is also an environment manager. With just a few commands, you can set up a totally separate environment to run that different version of Python, while continuing to run your usual version of Python in your normal environment.
