can't add a base64-encoded image to vCard

阅读更多关于 can't add a base64-encoded image to vCard

问题 I've successfully used Perl (via Embperl) to create a dynamically-generated vCard for employees, populating all the fields except for the photo. I can't get that working no matter what. (The code to generate a photo-less vCard works fine.) According to the information I can find online, the image must be base64-encoded in the vCard itself. The vCard spec (I'm using 3.0) supports URL-linked images, but my iPhone won't link to them that way. So it's base64 or nothing. Now, I know the base64

Is there any performance comparison between Perl web frameworks?

阅读更多关于 Is there any performance comparison between Perl web frameworks?

问题 I have seen mentions (which sounded like unsubstantiated opinions, and dated ones at that) that Embperl is the fastest Perl web framework. I was wondering if there's a consensus on the relative speed of the major stable Perl web frameworks, or ideally, some sort of fact-based performance comparisons between implementations of the same sample webapps, or individual functionalities (e.g. session handling or form data processing), etc...? UPDATE : This question is specifically about the speed
