Intuitive Interface Soulver offers a user-friendly interface that combines the simplicity of a notepad with the power of a calculator, making it easy to use even for non-technical users.
Live Calculations The app performs calculations as you type, providing real-time results without needing to press a special 'calculate' button.
Natural Language Processing Soulver understands natural language inputs, allowing you to write out calculations in plain English, which can be more intuitive than traditional formula-based approaches.
Versatile Units and Conversions The app can handle multiple types of units and perform conversions seamlessly, making it useful for various fields like engineering, finance, and everyday calculations.
Save and Organize Work Soulver allows users to save their work and organize it into files and folders, making it convenient to manage multiple projects or long-term records.
Cross-Platform Syncing With support for iCloud syncing, users can access their calculations across multiple Apple devices, maintaining continuity and ease of access.
Possible disadvantages
Mac and iOS Only Soulver is currently available only on Mac and iOS, limiting its accessibility for users on other platforms like Windows or Android.
Price Soulver is a paid application, and while it offers a lot of features, it might be considered expensive compared to free alternatives.
Learning Curve Despite its intuitive design, new users might take some time to fully understand all the features and capabilities of the software.
Limited Programming Capability While it's great for quick calculations and conversions, Soulver is not designed to handle more complex programming tasks or advanced statistical analysis, which might be a downside for power users.
No Android/Windows Sync Even if users have multiple devices, they can only sync their work across Apple devices, not with devices running on Android or Windows.
Dependency on Ecosystem Since it relies heavily on iCloud for syncing and other features, users are somewhat locked into the Apple ecosystem to get the most out of Soulver.
Efficient Concurrency Stackless Python provides microthreads, also known as tasklets, which offer efficient concurrency by allowing multiple tasks to run in a single thread without the overhead of traditional threading.
Simplified Code The microthreading model can lead to simplified code when compared to multithreading, as it avoids the complexities associated with locks and synchronization primitives.
Improved Performance Due to the avoidance of context switching between OS-level threads, Stackless Python can achieve improved performance for I/O-bound applications.
Flexibility Stackless Python allows developers to pause and resume functions at almost any point, providing great flexibility for creating advanced flow control mechanisms.
Low Memory Footprint Tasklets in Stackless Python are lightweight, leading to a lower memory footprint compared to traditional threading models.
Possible disadvantages
Compatibility Stackless Python may face compatibility issues with certain Python libraries and extensions that are not designed to work with its microthreading model.
Limited Community and Support Stackless Python has a smaller user base compared to standard Python, which can result in limited community support and fewer resources for learning and troubleshooting.
Platform Limitations Some platforms may not fully support or benefit from Stackless Python's features due to differences in underlying system architectures.
Debugging Challenges Debugging can be more challenging in Stackless Python due to its non-standard execution model, requiring developers to understand its unique flow control mechanisms.
Maintenance and Updates Since Stackless Python diverges from the standard Python implementation, it may lag in adopting new features and updates present in the latest Python releases.
Analysis
An editorial look at what each product does well and who it suits.
SoulverStackless Python
Overall verdict
Soulver is a good choice for users who need a more flexible tool for calculations than a traditional calculator or spreadsheet offers. Its blend of features makes it stand out as a versatile computational tool.
Why this product is good
Soulver is regarded as a unique hybrid between a calculator and a text editor, allowing users to perform calculations using natural language. It is particularly useful for those who work with numbers in a more narrative or exploratory context rather than in strict spreadsheet formats. Soulver is praised for its intuitive interface, ease of use, and ability to handle quick, ad-hoc calculations with ease.
Recommended for
People who need to perform quick calculations in a narrative or exploratory manner.
Users who appreciate an intuitive interface for number crunching without the rigidity of spreadsheets.
Professionals who require a seamless way to mix calculations with text for clear documentation and communication.
Overall verdict
Stackless Python is a solid, mature alternative Python implementation that excels at massive concurrency through lightweight microthreads (tasklets), making it a good choice for specific concurrent and cooperative multitasking workloads, though its niche status means smaller community support compared to CPython.
Why this product is good
Provides tasklets (microthreads) that allow hundreds of thousands of concurrent tasks with very low memory overhead
Offers channels for clean, safe communication and synchronization between tasklets without traditional locking headaches
Supports cooperative and preemptive scheduling, giving developers fine-grained control over concurrency
Enables serialization (pickling) of running tasklets, which is powerful for saving and migrating program state
Proven in production at scale, most famously powering the MMO game EVE Online
Largely maintains compatibility with standard CPython code and libraries
Recommended for
Developers building highly concurrent applications requiring massive numbers of lightweight threads
Game servers and simulations needing efficient cooperative multitasking (like EVE Online's use case)
Projects that benefit from tasklet serialization for state migration or persistence
Systems programmers exploring alternatives to threads or async frameworks for concurrency
Users comfortable working with a specialized Python distribution outside the mainstream CPython ecosystem

How does Go "know" when a goroutine hits IO and can switch to another goroutine? Why don't other languages like Javascript/Python do this?
For the sake of “well, actually” completionism, this is possible in Python with stackless or the gevent library and some hacks, but when Guido and pals backed the standard awful way of doing async in commercial languages (async/await and...
