Possible disadvantages of Python Package Index

  • Quality Assurance
    Not all packages on PyPI are of high quality or well-maintained. Some may have bugs, lack proper documentation, or not adhere to best practices, requiring users to vet packages carefully.
  • Security Risks
    There is a risk of downloading malicious packages since PyPI allows anyone to upload packages. Users need to be cautious and verify the credibility of the package authors and sources.
  • Dependency Management
    Managing dependencies can become complex, especially for large projects, as conflicts between package versions can arise, leading to potential runtime issues.
  • Overhead
    For smaller projects or those with specific needs, the sheer number of available packages can be overwhelming, making it difficult to find the most suitable one without investing a significant amount of time.
  • Legacy Packages
    Some packages on PyPI may no longer be maintained or updated, which can represent a risk if they become incompatible with newer versions of Python or other dependencies.

  • A PageSpeed insight report, but for every page in your domain
    Trust neither. The most optimal option I've found is webpagetest.org Its been quite handy lately. This tool does look interesting. Source: over 3 years ago
  • How are you all accurately checking your website load time? Not sure PageSpeedInsights is very helpful.
    Webpagetest.org is another. Pagespeedinsights and lighthouse are great for identifying page load issues to fix, but actual page load times will always vary between the user and your web server. Universal analytics has some page load timings but that's going away soon and nothing afaik is in GA4. I've seen an example of building a page load timer in tag manager and dumping the results into an event. Source: over 3 years ago
  • Extreme confusing over Speed Index results -- webpagetest.org
    So I am working on rebuilding our company's site with a new stack. I am running tests using webpagetest.org, and I am having trouble fully understanding the speed index results as well as the film strip view. The page renders quite fast everywhere I test it. Google Lighthouse shows it in the 90s + for performance score, however when I test the page on webpagetest, I get load times of 77 seconds (NOT MS) which is... Source: over 3 years ago
  • Does anyone else experience pure ecstasy when they get 100 on Lighthouse? 😩
    Webpagetest.org is great, and checking OP's site they have done an incredible job, I don't think I have ever made or seen an Ecom site this slick. Super clean waterfall view. Source: over 3 years ago
  • Performance scores for Google Lighthouse/Insights seem to be very inaccurate
    Thanks for the recommendation regarding webpagetest.org, another user made a similar recommendation so I will check it out. Source: over 3 years ago

  • 🐍 python pip vs pipenv vs poetry — which one should you actually use?
    Running pip install requests triggers this sequence: 1. Resolve requests to a distribution (wheel or sdist) from the index (default: https://pypi.org). 2. Download the artifact, verify its hash if available, and extract it. 3. Execute the build backend (setuptools, poetry-core, etc.) specified in pyproject.toml or setup.py to generate metadata. 4. Copy files into site-packages/ and populate .dist-info... - Source: dev.to / 4 months ago
  • How to write and publish a Python package to PyPI
    You need two accounts: test.pypi.org for the test registry, and pypi.org for the real registry that pip install and uv add use. Use the test registry first, since it resets periodically and will not pollute the real index with test uploads. Enable two-factor authentication on both, as PyPI requires it for publishing. - Source: dev.to / 4 months ago

    How does the big white search box at https://pypi.org/ work? Why couldn’t the same technology be used to power the CLI? If there’s an issue with abuse, I don’t think many people would mind rate limiting or mandatory authentication before search can be used. - Source: Hacker News / 8 months ago
