  • CSRF protection and cross site form access

    - by fl00r
    Hi. I aw working on cross site authentication (some domains have got common authentication). So I want to send authentication data (login, password) to main domain from others. How should I use protect_from_forgery and how can I check if data received from valid domain? What I am thinking now is to turn off protect_from_forgery for session controller and check domain name of received data. But maybe I can configure CSRF protection for not only one domain?

  • Cryptography: best practices for keys in memory?

    - by Johan
    Background: I got some data encrypted with AES (ie symmetric crypto) in a database. A server side application, running on a (assumed) secure and isolated Linux box, uses this data. It reads the encrypted data from the DB, and writes back encrypted data, only dealing with the unencrypted data in memory. So, in order to do this, the app is required to have the key stored in memory. The question is, is there any good best practices for this? Securing the key in memory. A few ideas: Keeping it in unswappable memory (for linux: setting SHM_LOCK with shmctl(2)?) Splitting the key over multiple memory locations. Encrypting the key. With what, and how to keep the...key key.. secure? Loading the key from file each time its required (slow and if the evildoer can read our memory, he can probably read our files too) Some scenarios on why the key might leak: evildoer getting hold of mem dump/core dump; bad bounds checking in code leading to information leakage; The first one seems like a good and pretty simple thing to do, but how about the rest? Other ideas? Any standard specifications/best practices? Thanks for any input!

  • ORA- 01157 / Cant connect to database

    - by Tom
    Hi everyone, this is a follow up from this question. Let me start by saying that i am NOT a DBA, so i'm really really lost with this. A few weeks ago, we lost contact with one of our SID'S. All the other services are working, but this one in particular is not. What we got was this message when trying to connect ORA-01033: ORACLE initialization or shutdown in progress An attempt to alter database open ended up in ORA-01157: cannot identify/lock data file 6 - see DBWR trace file ORA-01110: data file 6: '/u01/app/oracle/oradata/xxx/xxx_data.dbf' I tried to shutdown / restart the database, but got this message. Total System Global Area 566231040 bytes Fixed Size 1220604 bytes Variable Size 117440516 bytes Database Buffers 444596224 bytes Redo Buffers 2973696 bytes Database mounted. ORA-01157: cannot identify/lock data file 6 - see DBWR trace file ORA-01110: data file 6: '/u01/app/oracle/oradata/xxx/xxx_data.dbf' When all continued the same, I erased the dbf files (rm xxx_data.dbf xxx_index.dbf), and recreated them using touch xxx_data.dbf. I also tried to recreate the tablespaces using `CREATE TABLESPACE DATA DATAFILE XXX_DATA.DBF` and got Database not open As I said, i don't know how bad this is, or how far i'm from gaining access to my database (well, to this SID at least, the others are working). I would imagine that a last resource would be to throw everything away, and recreating it, but I don't know how to, and I was hoping there's a less destructive solution. Any help will be greatly appreciated . Thanks in advance.

  • What's the proper and reliable way to store an XML string as a JSON property?

    - by Edwin
    Hi Folks, I want to store a string which itself is an XML string as a property of an JSON object , what's the reliable and proper way of dong this? Should I first encode the XML data into BASE64 first prior saving it to an JSON object, due to the fact that JSON does not support binary data? Example of data I want to store: { "string1" : "...moderately complex XML..." } Thank you in advance for any hints and suggestions!

  • [Python] How can I speed up unpickling large objects if I have plenty of RAM?

    - by conradlee
    It's taking me up to an hour to read a 1-gigabyte NetworkX graph data structure using cPickle (its 1-GB when stored on disk as a binary pickle file). Note that the file quickly loads into memory. In other words, if I run: import cPickle as pickle f = open("bigNetworkXGraph.pickle","rb") binary_data = f.read() # This part doesn't take long graph = pickle.loads(binary_data) # This takes ages How can I speed this last operation up? Note that I have tried pickling the data both in using both binary protocols (1 and 2), and it doesn't seem to make much difference which protocol I use. Also note that although I am using the "loads" (meaning "load string") function above, it is loading binary data, not ascii-data. I have 128gb of RAM on the system I'm using, so I'm hoping that somebody will tell me how to increase some read buffer buried in the pickle implementation.

  • Easiest way to plot values as symbols in scatter plot?

    - by AllenH
    In an answer to an earlier question of mine regarding fixing the colorspace for scatter images of 4D data, Tom10 suggested plotting values as symbols in order to double-check my data. An excellent idea. I've run some similar demos in the past, but I can't for the life of me find the demo I remember being quite simple. So, what's the easiest way to plot numerical values as the symbol in a scatter plot instead of 'o' for example? Tom10 suggested plt.txt(x,y,value)- and that is the implementation used in a number of examples. I however wonder if there's an easy way to evaluate "value" from my array of numbers? Can one simply say: str(valuearray) ? Do you need a loop to evaluate the values for plotting as suggested in the matplotlib demo section for 3D text scatter plots? Their example produces: However, they're doing something fairly complex in evaluating the locations as well as changing text direction based on data. So, is there a cute way to plot x,y,C data (where C is a value often taken as the color in the plot data- but instead I wish to make the symbol)? Again, I think we have a fair answer to this- I just wonder if there's an easier way?

  • Entity Framework 4 and SQL Compact 4: How to generate database?

    - by David Veeneman
    I am developing an app with Entity Framework 4 and SQL Compact 4, using a Model First approach. I have created my EDM, and now I want to generate a SQL Compact 4.0 database to act as a data store for the model. I bring up the Generate Database Wizard and click the New Connection button to create a connection for the generated file. The Choose Data Source dialog appears, but SQL Compact 4.0 is not listed in the list of available data sources: I am running VS 2010 SP1 (beta) and I have installed the VS 2010 Tools for SQL Compact 4.0. I can create a SQL Compact 4.0 data connection from the Server Explorer. It is only in the Generate Database Wizard that the 4.0 option doesn't appear. BTW, my SQL Compact 4.0 installation does include System.Data.SqlServerCe.Entity.dll. So I should have the SQL Compact components I need. Am I doing something incorrectly, or is this a bug? Does anyone have a fix or a workaround? Thanks for your help.

  • Bound a treeview control to user-defined complex type using EF 4

    - by GIbboK
    Hi, I use Asp.net, SQL 2008 and EF 4. I need display hierarchy data in a treeview control, Data is stored in a DB that use HierarchyId. Unfortunately, EF4 doesn't support HierarchyId. So in this case, I thought to have a stored procedure that deals with my hierarchy and return a result set back to EF that EF4 can turn into a collection of user-defined complex type that can then be bound directly to the treeview control. I imported a SPROC in EF 4 using Import Function and now I have a Complex DataType called: CategoryHierarchy_Result An image of my Model: Here some data from the Complex Type (in a GridView for example GridView1.DataSource = context.CategoryHierarchy(1);): My questions is: How to display my data from my Complex Type in a TreeView Control, showing a Tree structure that respect CategoryNodeString? I am a beginner an I never use TreeView before, any help or resource would be appreciated! Thanks!. Here some useful resource: http://www.robbagby.com/entity-framework/entity-framework-modeling-action-stored-procedures/

  • Replacing a colour/colours in a movieclip with different colours?

    - by Oli
    I am trying to take a movieclip of a character and change the colour of their clothes. The character is comprised of vectors. So far I have semi-sucessfully used this method: stop the movieclip take the bitmap data from the current frame use threshold to replace the colour store the resulting bitmap data in an array add an onenterframe function - clear the current frame and add the bitmap data from the processed data in the array So - this works pretty well. Each frame is only processed once at the beginning and then the write to the movieclip is very quick. However! As the replacement is being performed on a bitmap there is an amount of aliasing that takes place to remove jaggies/pixelation. This produces colours that are not matched using threshold. So the main colour is replaced correctly but it is surrounded by a halo of mixed colours :( I am sure there should be a better way to do this. Any ideas or answers would be greatly apreciated - Thanks.

  • Integrating 3rd-party forum software to member-based website

    - by john
    When using some existing forum software in a larger web-site, how easy is it to: 1)Make your site's login functionality log the user into the forum 2)Make your site's registration functionality create forum login data I suppose in a way it might be easier to ONLY use the forum's database for maintaining users, but that means trusting it with sensitive data. I'm planning an integration between an existing bespoke desktop app and a new bespoke web-site which should include forums. I don't know which forums will be used but I know the new web functionality won't be PHP-based. I figure that's not a big deal but I'm wondering if forums typically allow configuration of where they look for login data, to avoid duplicating this data into my DB and the forum DB.

  • How to parse phpDoc style comment block with php?

    - by Reveller
    Please consider the following code with which I'm trying to parse only the first phpDoc style comment (noy using any other libraries) in a file (file contents put in $data variable for testing purposes): $data = " /** * @file A lot of info about this file * Could even continue on the next line * @author [email protected] * @version 2010-05-01 * @todo do stuff... */ /** * Comment bij functie bar() * @param Array met dingen */ function bar($baz) { echo $baz; } "; $data = trim(preg_replace('/\r?\n *\* */', ' ', $data)); preg_match_all('/@([a-z]+)\s+(.*?)\s*(?=$|@[a-z]+\s)/s', $data, $matches); $info = array_combine($matches[1], $matches[2]); print_r($info) This almose works, except for the fact that everything after @todo (including the bar() comment block and code) is considered the value of @todo: Array ( [file] => A lot of info about this file Could even continue on the next line [author] => [email protected] [version] => 2010-05-01 [todo] => do stuff... / /** Comment bij functie bar() [param] => Array met dingen / function bar() { echo ; } ) How does my code need to be altered so that only the first comment block is being parsed (in other words: parsing should stop after the first "*/" encountered?

  • Replacing Resource files on new BlackBerry app version

    - by Jeff
    Hello, I am maintaining an existing BlackBerry application (implemented as a MIDlet). The application contains a number of data files that get bundled with the app as resources. Some of these data files need to be updated for a new version of the app. When the user goes to install a new version of the application (via URL of Jad file), it prompts them with the following message "Persistent data exists for the application. Would you like to retain this data? " If the user selects "Yes", it looks like the app continues to use the old resource files. This is so surprising to me. First of all, am I losing my mind or will an upgrade really not overwrite existing resource files? Is there any way I can force it to? Thanks, Jeff

  • Drupal module permissions

    - by Trevor Newhook
    When I run the code with an admin user, the module returns what it should. However, when I run it with a normal user, I get a 403 error. The module returns data from an AJAX call. I've already tried adding a 'access callback' = 'user_access'); line to the exoticlang_chat_logger_menu() function. I'd appreciate any pointers you might have. Thanks for the help The AJAX call: jQuery.ajax({ type: 'POST', url: '/chatlog', success: exoticlangAjaxCompleted, data:'messageLog=' + privateMessageLogJson, dataType: 'json' }); The module code: function exoticlang_chat_logger_init(){ drupal_add_js('misc/jquery.form.js'); drupal_add_library('system', 'drupal.ajax'); } function exoticlang_chat_logger_permission() { return array( 'Save chat data' => array( 'title' => t('Save ExoticLang Chat Data'), 'description' => t('Send private message on chat close') ), ); } /** * Implementation of hook_menu(). */ function exoticlang_chat_logger_menu() { $items = array(); $items['chatlog'] = array( 'type' => MENU_CALLBACK, 'page callback' => 'exoticlang_chat_log_ajax', 'access arguments' => 'Save chat data'); //'access callback' => 'user_access'); return $items; } function exoticlang_chat_logger_ajax(){ $messageLog=stripslashes($_POST['messageLog']); $chatLog= 'Drupal has processed this.

  • Pass Linq Expression to a function

    - by Kushan Hasithe Fernando
    I want to pass a property list of a class to a function. with in the function based on property list I'm going to generate a query. As exactly same functionality in Linq Select method. Here I'm gonna implement this for Ingress Database. As an example, in front end I wanna run a select as this, My Entity Class is like this public class Customer { [System.Data.Linq.Mapping.ColumnAttribute(Name="Id",IsPrimaryKey=true)] public string Id { get; set; } [System.Data.Linq.Mapping.ColumnAttribute(Name = "Name")] public string Name { get; set; } [System.Data.Linq.Mapping.ColumnAttribute(Name = "Address")] public string Address { get; set; } [System.Data.Linq.Mapping.ColumnAttribute(Name = "Email")] public string Email { get; set; } [System.Data.Linq.Mapping.ColumnAttribute(Name = "Mobile")] public string Mobile { get; set; } } I wanna call a Select function like this, var result = dataAccessService.Select<Customer>(C=>C.Name,C.Address); then,using result I can get the Name and Address properties' values. I think my Select function should looks like this, ( *I think this should done using Linq Expression. But im not sure what are the input parameter and return type. * ) Class DataAccessService { // I'm not sure about this return type and input types, generic types. public TResult Select<TSource,TResult>(Expression<Func<TSource,TResult>> selector) { // Here using the property list, // I can get the ColumnAttribute name value and I can generate a select query. } } This is a attempt to create a functionality like in Linq. But im not an expert in Linq Expressions. There is a project call DbLinq from MIT, but its a big project and still i couldn't grab anything helpful from that. Can someone please help me to start this, or can someone link me some useful resources to read about this.

  • Starting with asp.net MVC

    - by Josemalive
    Hello, Actually im doing a home page that only have an action called Index() that returns the view Index.ascx. This index page will be composed by lastest news and lastest registered users, i think that create two partial views is the best idea (this way i could use it in other views). for other hand i have a data access class that calls to database for get stuff (get last news, get last users, etc...) My question is simple, should i call to the this data access class in the Index() action of my HomeController, and add to the ViewData the data obtained? I think that this index() action shouldnt be the responsable of passing this data to the partial views, right? Could you give me a hand? im messing too much? ;-) Thanks in advance. Best Regards.

  • Client-side or server-side processing?

    - by Nick
    So, I'm new to dynamic web design (my sites have been mostly static with some PHP), and I'm trying to learn the latest technologies in web development (which seems to be AJAX), and I was wondering, if you're transferring a lot of data, is it better to construct the page on the server and "push" it to the user, or is it better to "pull" the data needed and create the HTML around it on the clientside using JavaScript? More specifically, I'm using CodeIgniter as my PHP framework, and jQuery for JavaScript, and if I wanted to display a table of data to the user (dynamically), would it be better to format the HTML using CodeIgniter (create the tables, add CSS classes to elements, etc..), or would it be better to just serve the raw data using JSON and then build it into a table with jQuery? My intuition says to do it clientside, as it would save bandwidth and the page would probably load quicker with the new JavaScript optimizations all these browsers have now, however, then the site would break for someone not using JavaScript... Thanks for the help

  • How do you set the "global delimiter" in Excel using VBA (or unicorns)?

    - by DanM
    I've noticed that if I use the text-to-columns feature with comma as the delimiter, any comma-delimited data I paste into Excel after that will be automatically split into columns. This makes me think Excel must have some kind of global delimiter. If this is true, how would I set this global delimiter using Excel VBA? Is it possible to do this directly, or do I need to "trick" Excel by doing a text-to-columns on some junk data, then delete the data? My ultimate goal is to be able to paste in a bunch of data from different files using a macro, and have Excel automatically split it into columns according to the delimiter I set.

  • Managing important runtime business logic with regard to a codebase

    - by Daniel Beardsley
    I'm working on a project which will end up have a lot of application information stored in the form of records in a database. In this case, it's the configuration of data views: which grid columns to show/hide default filters to apply to each grid view column titles sorting subtotaling ... This information is a big part of the value of the application and is essential to it's function. The data will be altered by admins a fair amount, so it's not static and it wouldn't be appropriate to have to deploy a new version of the app every time the data changes. The question is, Where should this data be stored? It will definitely live in the database because that's how it's accessed, but I feel like it needs to also be kept with the version controlled codebase because it's an integral part of functioning of the application. Has anyone dealt with an issue like this before? What did you end up doing?

  • Using Pastebin API in Node.js

    - by wiill
    I've been trying to post a paste to Pastebin in Node.js, but it appears that I'm doing it wrong. I'm getting a Bad API request, invalid api_option, however I'm clearly setting the api_option to paste like the documentation asks for. var http = require('http'); var qs = require('qs'); var query = qs.stringify({ api_option: 'paste', api_dev_key: 'xxxxxxxxxxxx', api_paste_code: 'Awesome paste content', api_paste_name: 'Awesome paste name', api_paste_private: 1, api_paste_expire_date: '1D' }); var req = http.request({ host: 'pastebin.com', port: 80, path: '/api/api_post.php', method: 'POST', headers: { 'Content-Type': 'multipart/form-data', 'Content-Length': query.length } }, function(res) { var data = ''; res.on('data', function(chunk) { data += chunk; }); res.on('end', function() { console.log(data); }); }); req.write(query); req.end(); console.log(query) confirms that the string is well encoded and that api_option is there and set to paste. Now, I've been searching forever on possible causes. I also tried setting the encoding on the write req.write(query, 'utf8') because the Pastebin API mentions that the POST must be UTF-8 encoded. I rewrote the thing over and over and re-consulted the Node HTTP documentation many times. I'm pretty sure I completely missed something here, because I don't see how this could fail. Does anyone have an idea of what I have done wrong?
