  1. CakePHP

    CakePHP: The Rapid Development Framework for PHP - Official Repository

    Project mention: MessageFormat: Unicode standard for localizable message strings | news.ycombinator.com | 2026-02-16

    "the library just knows these rules for each language as part of the standard" sounds great until you try to support a small minority language that the library just doesn't know about and then you're left trying to hack around it by pretending that it's actually a regional variety of another language with similar plural rules.

    AFAIK, unlike gettext, MessageFormat doesn't allow you to specify a formula for the plural forms as part of the localization data, so the variant selection logic ended up in the hands of library developers rather than localizers or application developers.

    And the standard does get updated occasionally, which can also lead to bugs with localization data written against another version of the standard: https://github.com/cakephp/cakephp/issues/18740

  4. Easy!Appointments

    :date: Easy!Appointments - Self Hosted Appointment Scheduler

    Project mention: Cal.com is going closed source | news.ycombinator.com | 2026-04-15

    EasyAppointments (https://github.com/alextselegidis/easyappointments) is still FOSS. We managed our team calendars on it at a previous company, but I rolled out Cal.com due to more apparent support and sophistication at my current company. Turns out most of that sophistication turned out to be bloat: we saw successive version releases add features we didn't care about while increasingly putting previously open features, like team calendars, behind a paywall.

    This move by Cal.com seems to be transparently an attempt to maintain that paywall against users who'd otherwise just use LLMs to remove it. I guess it's back to EasyAppointments, which still seems to work just fine.

  12. Vulnerable-Web-Application

    OWASP Vulnerable Web Application Project https://github.com/hummingbirdscyber

    Project mention: Large Language Models for One-Day Vulnerability Detection | dev.to | 2025-09-16

    In order to evaluate the performance of the multi-agent system, a testing environment must be established. If an arbitrary target URL is provided and the LLMs generate a tailored output that detects the SQL Injection and XSS vulnerabilities on the site, there is no method to confirm the validity of the identified vulnerabilities if I do not have access to the underlying code of the website. In this case, purposely vulnerable websites were used as targets in order to preemptively know the confirmed number of SQL Injection and XSS vulnerabilities on each page. This information is then compared with the multi-agent system vulnerability assessment in order to grade its accuracy. The testing applications chosen for this project were Acunetix VulnWeb and OWASP Vulnerable-Web-Application as shown in the figures below.

  13. Elliptic-PHP

  15. Wolff

  16. vigilant

    Open Source All-in-One Web Monitoring (by govigilant)

    Project mention: Self Hostable Multi-Location Uptime Monitoring | dev.to | 2025-11-15

    This also allows us to check from multiple locations when a service is down with a small tradeoff that the detection takes a bit longer due to the additional checks. When an outpost responds with the message that a service is down it will check two additional outposts to ensure this is really the case. The small time tradeoff is worth it here to reduce the amount of false positives. For those who are interested, here is the source code for an uptime check.
