  • How to secure images with Rails?

    - by NotDan
    I have a gallery in my rails app that needs to only allow certain images to be shown to specific, logged in users. I am using Paperclip for image processing now, but it saves all images in a public folder available to anyone. Note that I don't have to use Paperclip if there is a better way, and I already have the login system in place. I just need a way to place the images in a non-public location, but still be able to serve them as needed. Is it possible to only allow these images to be served to authenticated users?

    In a system with both ends (client and server) in .NET, is it possible to use the binary serialization provided by the dataset class in ADO.NET 2.0 when the datasets are exposed as WebMethods parameters ?

  • Number of times a file (e.g., PDF) was accessed on a server

    - by Ivan
    I have a small website with several PDFs free for download. I use StatCounter to observe the number of page loads. It also shows me the number of my PDF downloads, but it considers only those downloads where a user clicks on the link from my website. But what's with the "external" access to the PDFs (e.g., directly from Google search)? How I can count those? Is there any possibility to use a tool such as StatCounter? Thanks.

  • Is there a good in-browser code editor?

    - by levik
    We've all seen in-browser rich text editors, which allow you to edit colored/styled text in a WYSIWYG manner. But what about code editors, which automatically highlight code based on language rules as you type? Think Eclipse in a textarea (but without the refactoring support). Do such things exist? I imagine scaling would be a problem - larger files would be difficult to edit efficiently.

  • What's the "correct way" to organize this project?

    - by user571747
    I'm working on a project that allows multiple users to submit large data files and perform operations on them. The "backend" which performs these operations is written in Perl while the "frontend" uses PHP to load HTML template files and determines which content to deliver. Data is stored in a database (MySQL, SQLite, Oracle) and while there is data which has not yet been acted upon, Perl adds it to a running queue which delivers data to other threads based on system load. In addition, there may be pre- and post-processing of the data before and after the main Perl script operates (the specifications are unclear) so I may want to allow these processors to be user-selectable plugins. I had been writing this project in a more procedural fashion but I am quickly realizing the benefit of separating concerns as to limit the scope one change has on the rest of the project. I'm quite unexperienced with design patterns and am curious what the best way to proceed is. I've heard MVC thrown around quite a bit but I am unsure of how to apply it. Specifically, what are some good options to structure this code (in terms of design patterns and folder hierarchy)? How can I achieve this with both PHP and Perl while minimizing duplicated code between languages? Should I keep my PHP files in the top level so I don't have ugly paths in the URL? Also, if I want to provide interchangeable databases, does each table need its own DAO implementation?

  • How To Collapse Just One Field in Django Admin?

    - by Apreche
    The django admin allows you to specify fieldsets. You properly structure a tuple that groups different fields together. You can also specify classes for certain groups of fields. One of those classes is collapse, which will hide the field under a collapsable area. This is good for hiding rarely used or advanced fields to keep the UI clean. However, I have a situation where I want to hide just one lonesome field on many different apps. This will be a lot of typing to create a full fieldset specification in every admin.py file just to put one field into the collapsed area. It also creates a difficult maintenance situation because I will have to edit the fieldset every time I edit the associated model. I can easily exclude the field entirely using the exclude option. I want something similar for collapse. Is this possible?

    - by Genadinik

  • Screenscraping and reverse engineering health based web tool

    - by ArbInv
    Hi There is a publicly available free tool which has been built to help people understand the impact of various risk factors on their health / life expectancy. I am interested in understanding the data that sits behind the tool. To get this out it would require putting in a range of different socio-demographic factors and analyzing the resulting outputs. This would need to be done across many thousand different individual profiles. The tool was probably built on some standard BI platorm. I have no interest in how the tool was built but do want to get to the data within it. The site has a Terms of Use Agreement which includes: Not copying, distribute, adapt, create derivative works of, translate, or otherwise modify the said tool Not decompile, disassemble, reverse assemble, or otherwise reverse engineer the tool. The said institution retains all rights, title and interest in and to the Tool, and any and all modifications thereof, including all copyright, copyright registrations, trade secrets, trademarks, goodwill and confidential and proprietary information related thereto. Would i be in effect breaking the law if i were to point a screen scraping tool which downloaded the data that sits behind the tool in question?? Any advice welcomed? THANKS

  • Different CSS Styles

    - by Nimbuz
    /* Style 1 */ .myclass { background:#ff0; border:1px solid #ff0 } #myid { width:80px; height:80px; } /* Style 2 */ .myclass { background:#ff0; border:1px solid #ff0 } #myid { width:80px; height:80px; } I'm sure there must be more styles for writing CSS, I'd like to know what are they. Is there an article already written that lists all styles. Thanks

  • Using PHP Frameworks to get Web 2.0 or Ajax and Other Special Features

    - by user504958
    I'm still struggling to understand when or how to use a framework such as Zend or Yii. Here's some of the features I'm going to need on my next project and I don't understand frameworks well enough to know where the framework fits into the picture. I won't say exactly what the project is but think about something like Yelp or Merchant Circle, on a smaller scale of course - a directory project. It will contain a search box and links to all and/or popular categories. 1) Autosuggest in Search box. (I already know how to do this using jQuery) 2) Analyze the search terms entered into the search box to determine if they misspelled a word. Offer to correct the misspelling or automatically correct the word and show relevant results. 3) Offer items, links, or ads that are related to their search term. 4) Allow users to determine which fields are shown. 5) Allow users to sort the results however they choose. 6) Allow editing of records on a grid/list view. Post form without refreshing the page. Delete or Add records without going to a different page or reloading the current page.

  • Hosting an Access DB

    - by Mitciv
    Hey, So I'm inexperienced in hosting DB's and I've always had the luxury of someone else getting the db setup. I was going to help a friend out with getting a webpage setup, I've got experience in Asp.Net MVC so I'm going with that. They want to setup a search page to query a db and display the results. My question I have is in getting the DB setup and hosted. They currently just have the Access DB on a local computer. There is basically only one table that would need to be queried for the search. What is the best approach to getting this table/db accessible? They would like to keep the main copy of the db on the local machine, so copying the entire db over to the hosted site would be time consuming, could the lone table needed be solely copied to the host? Should I try to convince them to make changes on the hosted db and just make copies of that for their local machines? Any suggestions are welcome, Again I'm a total noob when it comes to hosting databases. Thanks

  • Profilers for ASP.Net Web Applications?

    - by Earlz
    I was recently wanting to do some profiling on an ASP.Net project and was surprised to see that Visual Studio (at least seems to be) lacking a profiler. So my question is what profiler do you use for ASP.Net? Are there any decent ones out there that are free? I've seen a few general .Net profilers but have yet to see one that can be used with ASP.Net..
