Possible disadvantages of CodePen

  • Limited Offline Functionality
    Since CodePen is primarily an online tool, it requires an internet connection for most of its features to work, limiting its usefulness in offline environments.
  • Performance Constraints
    Complex or resource-intensive projects may not perform as well on CodePen as they would in a full-fledged local development environment.
  • Subscription Costs
    While many features are free, advanced functionalities and additional storage options require a paid subscription, which may not be ideal for all users.
  • Limited Backend Capabilities
    CodePen is primarily designed for front-end development, so it offers limited support for backend technologies, making it less suitable for full-stack or server-side development.
  • Dependency Management
    Managing dependencies and libraries can be cumbersome compared to local development environments which have better tools for this purpose, like npm.
  • Security Concerns
    Sharing projects with the public can expose your code and assets to unauthorized use, posing potential intellectual property and security risks.

  • Open Source

Possible disadvantages of Rspamd

  • Complex Configuration
    Setting up and configuring Rspamd may be complex for users without advanced technical skills, requiring a deep understanding of its architecture and components.
  • Limited Documentation
    The available documentation may be insufficient for some users, making it harder to troubleshoot issues or fully utilize all features.
  • Community Support Dependent
    Being an open-source project, support can be limited and largely relies on community interaction and available public resources.
  • Potential Overhead
    While optimized for performance, inappropriate configuration can lead to unnecessary system load, impacting overall server performance.

  • Ok, I've migrated email to selfhosted
    Spamassassin or rspamd or ASSP. All very good. Spamassassin just works, but you need to feed it a good cohort of spam and ham (about 1000 messages each). Most people only send it the spam which will then bias it quite a bit and not have it classify spam as spam unless it's the worst of the bunch. Spamassassin is a filter for your mail server. Rspamd is the same idea. ASSP is highly configurable and a proxy. Source: about 3 years ago
  • SpamMail
    Https://rspamd.com/ is what we use on our mail servers blocks around 60% of incoming emails some get thu but not a lot. Source: about 3 years ago
  • Tell HN: Gmail's spam filters have gone bonkers
    Definitely. I think Gmail spam filtering has just gone haywire with way too much input, ChatGPT style sales pitches, and too much clutter. At Skiff (https://skiff.com/mail), we use RSPAMD (https://rspamd.com/), an open-source spam filtering framework. It's not as sophisticated, but it is highly explainable and works consistently. I much prefer this + inbox rules to anything else. - Source: Hacker News / over 3 years ago
  • DKIM Migration: Rpamd instead of DKIMproxy out on OpenBSD / OpenSMTPD
    When I installed Rspamd with on OpenBSD / OpenSMTPD the other day, DKIMProxy out (dkimproxy_out daemon), which had been got via OpenBSD Ports package system, was used to add DKIM signatures to mails in order to improve security on emails. - Source: dev.to / about 5 years ago

    Well, Rspamd includes web interface to monitor its performance. I combined it with relayd. - Source: dev.to / about 5 years ago
