  • Dealing With Java Default Level Access Specifiers

    - by Tom Tresansky
    I've seen some code in a project recently where some fields in a couple classes have been using the default access modifier without good reason to. It almost looks like a case of "oops, forgot to make these private". Since the classes are used almost exclusively outside of the package they are defined in, the fields are not visible from the calling code, and are treated as private. So the mistake/oversight would not be very noticeable. However, encapsulation is broken. If I wanted to add a new class to the existing package, I could then mess with internal data in objects using fields with default access. So, my questions: Are there any best practices concerning default access specifiers that I should be aware of? Anything that would help prevent this type of accident from re-occurring? Are are any annotations which might say something to the effect of "I really meant for these to be default access"? Using CheckStyle, or any other Eclipse plugins, is there any way to flag instances of default fields, or disallow any not accompanied by, say, a "//default access" comment trailing them?

  • Multiple Rails forks with separate designs and layouts

    - by mettadore
    I have a Rails project that is basically a simple web app for a membership-based organization. We've open sourced the code on Github for the web app so that others can use it, but have a licensed design/layout that the original organization is going to use. This layout cannot be open sourced. I was wondering if others have run into the situation where you have an open-source Rails app with a non-OS design. My initial thought is to put app/views in .gitignore, and to have anyone forking the code add their own views directory, perhaps including an app/views_default directory with a web-app-theme layout or something else to get people running. Is this the best option (realizing that there are other files such as JavaScript, CSS, etc that come with the layout that must also be ignored). Does anyone have some good thoughts or pointers on this?

  • 398 row datalist slowing down modal open????

    - by Jreeter
    Hey guys I got a weird issue.. I have a datalist that's only loaded on pageload it contains 2 columns a name and date and has 398 rows.. In IE 7 and above(and prob previous version) when I open a modal via a button click it takes almost 5 seconds to open. HOWEVER, if I do not bind this datalist it's MUCH faster.. Also this is only happening in IE, Chrome, Firefox and opera both open the modal instantly with the datalist binded... Josh

  • Visual Studio Default Open File Action

    - by Kleinux
    I am using Visual Studio 2008 with C#. Is there a way to set the default editor for a class file containing a DataTable derived class? Whenever I double click on one of these classes to open the file VS attempts to open a component designer. Since my class isn't compatible with that editor this is a rather useless default. I would like these files to open up in the normal code editor.

  • facebook extended access token login

    - by Pota Onasys
    I have the following code: $facebook = new Facebook(array( 'appId' => ID, 'secret' => SECRET, 'cookie' => true)); $fb_uid = $facebook->getUser(); if($fb_uid) { // check if person with fb_uid as facebook id in database, // if so log them in. If not, register them. $fb_user = $facebook->api('/' . $fb_uid); I then get their email address using $fb_user['email'] and facebook_id and store in the database as a means to log them in the future Sometimes $fb_uid returns false even though the person is logged in using facebook ... I think it is because the access token expires. how can I change this code to incorporate the extended access token to log in the user to my site? offline access token is deprecated, so I need to use the extended access token.

  • Are SqlCipher open cursors a security concern?

    - by user1178479
    I'm using SqlCipher with content providers. Right now, when I want to lock the app I just clear out the cached password. However, the app can continue to work with any open cursors. This means that re-opening the app grants access to the sensitive data. I fix this issue on the surface by redirecting to a login screen if the app doesn't have passwords. However, I'm concerned if there are any security issues with these open cursors or if I should just continue to block UI access and not worry? SqlCipher's docs say that it reads/writes encrypted pages on the fly, as opposed to decrypting the entire DB, this makes me think that open cursors are still secure. The main concern here is that someone loses their phone and then a knowledgeable individual can use these open cursors to extract sensitive data.

  • can i use hadoop cloudera without root access?

    - by in_the_cloud
    a bit of a binary question (okay, not excatly) - but was wondering if one is able to configure cloudera / hadoop to run at the nodes without root shell access to the node computers (although i can setup ssh passwordless login)? appears from their instructions that root access is needed, at yet i found a hadoop wiki which suggest root access might not be needed ? http://wiki.apache.org/nutch/NutchHadoopTutorial

  • How to control access to third party HTML pages

    - by Wylie
    Hello, We have a Learning Management System (LMS) that runs on its own server (IIS/Server 2003). Students must login with Forms authentication to gain access to the content. We want to offer access to third party flash and audio that is embedded in HTML pages hosted on the third party server (IIS/Server 2003). Currently we use a frame in a pop-up window that is populated via a simple URL to the third party HTML pages. How can the third party control access to their content, so that only students who launch the pop-up windows from our site can access their content? Since the content is mostly video and flash, we would prefer not to stream all of their content through our server to the Student. We have a programming staff, so we could maybe... - either post or get for our HTTP request to the third party server - we could use SSL - we could programmatically assign a global NT user account to all of our users and then do some kind of Active Directory login from the LMS server to the third party server - could the third party content be hosted at Amazon S3? Would this allow for secure access/download? These are just ideas. We really have no idea. Any suggestions would be greatly appreciated. TIA, Wylie

  • R language: open ssh connection

    - by marpo_it
    I am trying to open a remote shell via ssh to send commands from R. As long as I send commands, I need to get results and send new commands that depends on the output of the previous ones. For this reason I am looking for a solution to open a connection and manage it from within the R code until I have finished. I also need to open the connection with ssh key exchange (so without password authentication). Looking at CRAN I didn't find anything useful.

  • Formatting not retained in paste from Ditto (clipboard manager). Plain text pasted instead [Solved] Add supported types

    - by Jeff Kang
    I'm trying to use Ditto on the Ditto documentation. If I were to copy the table of contents, then paste it (without Ditto) to the word processor, I get http://i.imgur.com/V1GU3.png, and the formatting is maintained. As as a result of the copy operation, the table of contents also goes into the Saved Items List (= History List = Lists the Clips saved from the Clipboard) in Ditto’s Main Window: I open a blank document to paste from Ditto instead of the default clipboard, and press either Ctrl-`, the default Ditto window activation Global Hot Key, or click the tray icon. From this point, I can do 3 things to close the Ditto window, and place the item on the clipboard (the default clipboard?). Select the item, and press Enter Put the cursor on the item, and double-click Select the item, and press Ctrl-c 1) and 2) send a right-click where the cursor is, after the Ditto window closes (presumably to have the paste option ready to access?): Ctrl-c just closes the Ditto window. Whichever method is used, the contents are pasted in what I believe is plain text: http://i.imgur.com/mQAZH.png How do I keep the formatting that the default clipboard keeps? Thanks.

    - by mdemmitt
    Hi all, In my Java servlet code, I want to be able to programatically write to the jetty access log. I am aware that jetty will automatically log every incoming HTTP request to the access log. However, my servlet needs to occasionally append it's own line to the access log. Has anyone here done something similar? Thanks!
