  • Rails: Convert HTML to PDF?

    - by rip747
    What is the best and easiest way of taking HTML and converting it into a PDF, similar to use CFDOCUMENT on ColdFusion? UPDATE: I really appreciate all the comments and suggestions that people have given so far, however I feel that people leaving their answers are missing the point. 1) the solution has to be free or open sourced. one person suggested using pricexml and the other pd4ml. both of these solutions costs money (pricexml costing an arm and a leg) which i'm not about the fork over. 2) they must be able to take in html (either from a file, url or a string variable) and then produce the pdf. libraries like prawn, rprf, rtex are produced using their own methods and not taking in html. please don't think i'm ungrateful for the suggestions, it's just that pdf generation seems like a really problem for people like me who use ColdFusion but want to convert to Rails.

  • Ooutsourcing design/programming (taxes!)

    - by alexeypro
    Hello, I have a full time job, but I also have some ideas in mind -- and I want to outsource some code development and design to Russia. I have friends there who help me to do that -- they'll do the development, provide me invoice (which is just description of our terms, because we decided on flat rate monthly fee), and I need to wire them money. So, I do not have business entity. If I'll pay them, am I am required to pay taxes? Or do I deduct my business expenses (say $30K/year) from my earnings (say $50K/year), and pay taxes only on what's left ($20K to be precise)? Any rules on that? Am I limited with something here? Thanks!

  • User account design and security...

    - by espinet
    Before I begin, I am using Ruby on Rails and the Devise gem for user authentication. Hi, I was doing some research about account security and I found a blog post about the topic awhile ago but I can no longer find it again. I read something about when making a login system you should have 1 model for User, this contains a user's username, encrypted password, and email. You should also have a model for a user's Account. This contains everything else. A User has an Account. I don't know if I'm explaining this correctly since I haven't seen the blog post for several months and I lost my bookmark. Could someone explain how and why I should or shouldn't do this. My application deals with money so I need to cover my bases with security. Thanks.

  • Programmatically convert a video to FLV

    - by Raibaz
    Hi all, i am currently working on a web application that needs to accept video uploaded by users in any format (.avi, .mov, etc.) and convert them to flv for playing in a flash-based player. Since the site is OpenCms-based, the best solution would be a ready-made plugin for OpenCms that allowed to upload and play videos doing the transcode operation in background, but just a set of Java classes to do the transcode would be great and then i could make the uploading form and playback part on my own.

  • Alternative to google map api, so that I can use it on a HTTPS/SSL encrypted website.

    - by Zeeshan Rang
    I have a question regarding map api. I was using the the google map api in my website before. But since I have encryption the site using HTTPS/SSL support, the google map api stopped working. I checked online, and realised that google has a Premier account only that would allow me to use HTTPS supported maps api and it cost $10,000 per year. I do not this kind of money with me. So, can you give any other alternative to have a map api on my website. Anything that could give me driving directions would be fine. Regards Zeeshan

  • Who pays developers of open-source software?

    - by darko petreski
    We are facing a lot of open source software. But someone needs to write that software. How are they payed? Do you know a good article about the open source politics and economy? Sometimes the big companies themselves release open source because they have some benefits. Then they sell support, advices ... My question is what is the real economy about open software? No professional will work for nothing. This software are couple of classes but thousand or may be millions of classes. If you are really a pro you will write software for money, because you have life, wife, kids, taxes, you must earn. Please do not tell me that they are doing this for pleasure or hobby!

  • Embed XAML in XML Schema

    - by Michael Stoll
    I'm developping a xml data format. Besides other data there should be a xaml drawing. So I wanted to have a xml element, which can contain any valid xaml. How can this be expressed in the XML Schema? I tried to import the xaml schema, but I couldn't find a xsd file for it. The makeshift would be to use an encoded string.

  • What can I use for voluntary donations? (like Tipjoy)

    - by Ken
    There used to be a site called Tipjoy that would let me put a small "donate" button on a webpage, and users could donate small amounts (like 25c) to me easily. I think it was a pretty neat idea, since I want to have a way for people to give me money, and I don't like advertisements, and I don't update regularly enough to sell subscriptions like bloggers. I just have some simple web services and open-source program and I want an easy way for people to drop me some change if they think they're useful. I've found out that Amazon used to have a similar service, but it's also been shut down. Is there any similar web service available today? If not, what's the closest thing to offer -- a Paypal link?

  • Tools to work with App Engine data dumps

    - by Thilo
    Using the bulkloader.py utility you can download all data from your application's Datastore. It is not obvious how the data is stored, however. From the looks of it, you get a SQLite file with all data in binary format in a single table: sqlite> .tables bulkloader_database_signature result sqlite> .schema result CREATE TABLE result ( id BLOB primary key, value BLOB not null, sort_key BLOB); Are there any tools to work with this data?

  • Freelancer's problem and legal actions

    - by user198003
    Hi, Last year, I worked as a free lancer on one project. Unfortunately, person I worked for, decided that he is not happy about my work, and he decided to fired me. After 7 months, he called me, and ask to me return "his" money. In any other case, he will sue me. His version is that I have to give him 1500 euros, but my version is that he own me another 1500. I have no contract, only emails and Excel file with counted hours. What do I have to do? I don't want to give him back 1500, because it was my work, and his bad management. Also, I do not want my 1500, because I think it's not fair from my side. What should I do?
