Setting up Your Environment
APPENDIX A Setting Up Your Environment Choosing the correct tools to work with asyncio is a non-trivial choice, since it can significantly impact the availability and performance of asyncio. In this appendix, we discuss the interpreter and the packaging options that influence your asyncio experience. The Interpreter Depending on the API version of the interpreter, the syntax of declaring coroutines change and the suggestions considering API usage change. (Passing the loop parameter is considered deprecated for APIs newer than 3.6, instantiating your own loop should happen only in rare circumstances in Python 3.7, etc.) Availability Python interpreters adhere to the standard in varying degrees. This is because they are implementations/manifestations of the Python language specification, which is managed by the PSF. At the time of this writing, three relevant interpreters support at least parts of asyncio out of the box: CPython, MicroPython, and PyPy. © Mohamed Mustapha Tahrioui 2019 293 M. M. Tahrioui, asyncio Recipes, https://doi.org/10.1007/978-1-4842-4401-2 APPENDIX A SeTTinG Up YouR EnViROnMenT Since we are ideally interested in a complete or semi-complete implementation of asyncio, our choice is limited to CPython and PyPy. Both of these products have a great community. Since we are ideally using a lot powerful stdlib features, it is inevitable to pose the question of implementation completeness of a given interpreter with respect to the Python specification. The CPython interpreter is the reference implementation of the language specification and hence it adheres to the largest set of features in the language specification. At the point of this writing, CPython was targeting API version 3.7. -
Python Crypto Misuses in the Wild

However, our data and ensure confidentiality. For example, without crypto, these studies have been conducted on Java and C, while empirical we would not be able to securely use online banking or do online studies for other languages are missing. For example, a controlled shopping. Unfortunately, previous research results show that crypto user study with crypto tasks in Python has shown that 68.5 % of the is often used in an insecure way [3, 4, 7, 9, 11]. One such problem is professional developers write a secure solution for a crypto task. the choice of an insecure parameter, like an insecure block mode, for Aims: To understand if this observation holds for real-world code, crypto primitives like encryption. Many static analysis tools exist we conducted a study of crypto misuses in Python. Method: We to identify these misuses such as CryptoREX [13], CryptoLint [4], developed a static analysis tool that covers common misuses of5 CogniCryptSAST [8], and Cryptoguard [12]. different Python crypto APIs. With this analysis, we analyzed 895 While these tools and the respective in-the-wild studies concen- popular Python projects from GitHub and 51 MicroPython projects trate on Java and C, user studies suggest that the existing Python for embedded devices. -

Having USB built in allows the chip to act like any USB device. For example, we can program the chip to 'pretend' it's a USB joystick, or a keyboard, or a flash drive! Another nice bonus of having USB built in is that instead of having an FTDI chip or cable (like an Arduino), we can emulate the serial port directly in the chip. This costs some Flash space and RAM space but that's the trade-off. The only bad news about this chip is that it is surface mount only (SMT), which means that it is not easy to solder the way the larger DIP chips are. For that reason, we made a breakout board. The board comes with some extras like a fuse, a 16mhz crystal, USB connector and a button to start the bootloader. -

Bfree: Enabling Battery-Free Sensor Prototyping with Python
BFree: Enabling Battery-free Sensor Prototyping with Python VITO KORTBEEK, Delft University of Technology, The Netherlands ABU BAKAR, Northwestern University, USA STEFANY CRUZ, Northwestern University, USA KASIM SINAN YILDIRIM, University of Trento, Italy PRZEMYSŁAW PAWEŁCZAK, Delft University of Technology, The Netherlands JOSIAH HESTER, Northwestern University, USA Building and programming tiny battery-free energy harvesting embedded computer systems is hard for the average maker because of the lack of tools, hard to comprehend programming models, and frequent power failures. With the high ecologic cost of equipping the next trillion embedded devices with batteries, it is critical to equip the makers, hobbyists, and novice embedded systems programmers with easy-to-use tools supporting battery-free energy harvesting application development. This way, makers can create untethered embedded systems that are not plugged into the wall, the desktop, or even a battery, providing numerous new applications and allowing for a more sustainable vision of ubiquitous computing. In this paper, we present BFree, a system that makes it possible for makers, hobbyists, and novice embedded programmers to develop battery-free applications using Python programming language and widely available hobbyist maker platforms. BFree provides energy harvesting hardware and a power failure resilient version of Python, with durable libraries that enable common coding practice and off the shelf sensors. We develop demonstration applications, benchmark BFree against battery-powered
