hi, i'm daniel. i'm a 15-year-old with some programming experience and i do a little bug hunting in my free time. here's the insane story of how I found a single bug that affected over half of all Fortune 500 companies:

say hello to zendesk

If you've spent some time online, you’ve probably come across Zendesk.

Zendesk is a customer service tool used by some of the world’s top companies. It’s easy to set up: you link it to your company’s support email (like [email protected]), and Zendesk starts managing incoming emails and creating tickets. You can handle these tickets yourself or have a support team do it for you. Zendesk is a billion-dollar company, trusted by big names like Cloudflare.

Personally, I’ve always found it surprising that these massive companies, worth billions, rely on third-party tools like Zendesk instead of building their own in-house ticketing systems.

Solving CORS problem on embedding Pentaho CDE dashboard in web application

Cross-Origin Resource Sharing (CORS) is a W3C spec that allows cross-domain communication from the browser. By building on top of the XMLHttpRequest object, CORS allows developers to work with the same idioms as same-domain requests.

Enable Cross Origin Resource Sharing (CORS) in the Community Dashboard Framework (CDF), Community Dashboard Editor (CDE), and Community Data Access (CDA). While you need CDE to embed the dashboard, you will access it from a different server other than the Pentaho Server, so CORS must be enabled in CDF, CDE and CDA. Open the following CDF, CDE, and CDA settings.xml files in a text editor:

• For CDF: server/pentaho-server/pentaho-solutions/system/pentaho-cdf/settings.xml.
• For CDE: server/pentaho-server/pentaho-solutions/system/pentaho-cdf-dd/settings.xml.
• For CDA: server/pentaho-server/pentaho-solutions/system/cda/settings.xml.
