Qwant features and specs

  • Privacy
    Qwant emphasizes user privacy by not tracking or collecting personal data for targeted advertising, which helps users maintain a higher level of anonymity online.
  • No Filter Bubble
    Unlike some other search engines, Qwant does not create a filter bubble, meaning users are not shown results based on their previous searches, helping them see a more unbiased array of search results.
  • Data Neutrality
    Qwant ensures its search results are not influenced by advertisers, providing unbiased and impartial search results.
  • Ad-Free Experience
    The search results on Qwant are clutter-free and do not heavily promote ads, offering a cleaner and more focused search experience.
  • Ethical Stance
    Qwant positions itself as an ethical alternative to major search engines, appealing to users who are conscious of their digital footprint and data sovereignty.

Possible disadvantages of Qwant

  • Search Result Relevance
    Compared to major search engines like Google, Qwant's search algorithm may not always provide the most relevant or comprehensive results.
  • Smaller Ecosystem
    Qwant lacks the extensive ecosystem of interconnected services (such as email, maps, and cloud storage) that systems like Google offer.
  • Market Penetration
    Qwant is less widely known and used than its major competitors, which can influence the continual improvement and data breadth for refining search algorithms.
  • Language and Localization
    Qwant may not support as many languages or have as strong localization as other more established search engines, potentially limiting its usability for non-English speaking users.
  • Advanced Search Features
    Qwant may not have as many advanced search features as other search engines, potentially limiting its functionality for power users who need specialized tools.

Stackless Python features and specs

  • 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 of Stackless Python

  • 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 of Stackless Python

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

Qwant mentions (22)

  • Migrating to the EU
    For search, I'd suggest Ecosia [1] or Qwant [2] if you don't mind ads, or Uruky [3] if you don't want them (full disclosure, I've created Uruky with my wife). [1]: https://ecosia.org [2]: https://qwant.com [3]: https://uruky.com. - Source: Hacker News / 6 months ago
  • Is this censorship or is the site just broken?
    If you go to ecosia.org or qwant.com on any mobile browser (Safari, Chrome, etc.,.) and search for ghandi you also get no results. Its only when the search query ends in ghandi, for example "ghanid date of birth" returns results fine. Source: over 3 years ago
  • James O'Keefe on Project Veritas Being Suspended by YouTube over Blockbuster Pfizer Expose
    Use qwant.com - DuckDuckGo is also useless. I haven't found anything better and I'm really happy with it. Source: over 3 years ago
  • Pathetic, Google.
    Why don’t you try Qwant? Brave Search and Ecosia are also good options, but DuckDuckGo’s results are a little lacking. Source: almost 4 years ago
  • Just switched to Linux now going to switch to duck duck go
    DuckDuckGo is turning into the next Google. Try another search engine like brave browser or qwant.com. Source: about 4 years ago

  • 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 colored functions) this practice fell by the wayside.
