• Established javascript solution for secure registration & authentication without SSL

  - by Tomas

  Is there any solution for secure user registration and authentication without SSL? With "secure" I mean safe from passive eavesdropping, not from man-in-the-middle (I'm aware that only SSL with signed certificate will reach this degree of security). The registration (password setup, i.e. exchanging of pre-shared keys) must be also secured without SSL (this will be the hardest part I guess). I prefer established and well tested solution. If possible, I don't want to reinvent the wheel and make up my own cryptographic protocols. Thanks in advance.

• Command to surround a character with spaces in vim

  - by William Becker

  I am trying to use vim properly - to aid me I've mapped my arrow keys to "" so that I am forced to use {hjlk} to move around. This is causing me a problem when I want to just surround a character with spaces, eg: "2+3" is better formatted "2 + 3" Previously I would have put my cursor over the + and typed: i[space][arrow-right][space][Esc] That's 5 presses. To do this without the arrow I seem to need to put the cursor over the + and go: i[space][Esc]lli[space][Esc] That's 8 presses. I can convert the "li" into an "a" which reduces it to 7 presses: i[space][Esc]la[space][Esc] Short of writing this into a macro is there a better way of doing it? Is there some magic vim command which will allow me to do it in less than even 5 presses - and some way to generalise it so that I can do it to entire words or symbols, eg if I want to convert 3==4 to 3 == 4?

• Disabling identity (auto-incrementing) on integer primary key using code first

  - by gw0

  I am using code first approach in a ASP.NET MVC 3 application and all integer primary keys in models (public int Id { get; set; }) are by default configured as an identity with auto-incrementing. How to disable this and enable a way to manually enter the integer for the primary key? The actual situation is that the Id integers have a special meaning and I would therefore like to have them choosable at creation and later editable. It would be ideal if in case the integer is not given at creation time it is auto-incremented, else the specified value is used. But editable primary fields is my primary need. Is there any way to do this elegantly in ASP.NET MVC 3?

• Multiple key map in c++

  - by Morgan

  Hi, I'm wondering if any of you know of a c++ associative map container type which I can perform multiple key lookups on. The map needs to have constant time lookups but I don't care if it's ordered or unordered. It just needs to be fast. For example, I want to store a bunch of std::vector objects in a map with an integer and a void* as the lookup keys. Both the int and the void* must match for my vector to be retrieved. Does anything like this exist already? Or am I going to have to roll my own. If so, any suggestions? I've been trying to store a boost::unordered_map inside another boost::unordered_map, but I have not had any success with this method yet. Maybe I will continue Pershing this method if there is no simpler way. Thanks!

• Storing tree data in Javascript

  - by Ozh

  I need to store data to represent this: Water + Fire = Steam Water + Earth = Mud Mud + Fire = Rock The goal is the following: I have draggable HTML divs, and when <div id="Fire"> and <div id="Mud"> overlap, I add <div id="Rock"> to the screen. Ever played Alchemy on iPhone or Android? Same stuff Right now, the way I'm doing this is a JS object : var stuff = { 'Steam' : { needs: [ 'Water', 'Fire'] }, 'Mud' : { needs: [ 'Water', 'Earth'] }, 'Rock' : { needs: [ 'Mud', 'Fire'] }, // etc... }; and every time a div overlaps with another one, I traverse the object keys and check the 'needs' array. I can deal with that structure but I was wondering if I could do any better? Edit: I should add that I also need to store a few other things, like a short description or an icon name. So typicall I have Steam: { needs: [ array ], desc: "short desc", icon:"steam.png"},

• Set primary key on hibernate generated sequence table

  - by bungrudi

  setup: hibernate 3.3, MySQL 5 I have an hibernate entity that have its PK generated using a sequence table. The annotation looks like this: @GenericGenerator(name = "SCENARIO_TABLE_GEN", strategy = "org.hibernate.id.enhanced.TableGenerator", parameters = { @Parameter(name = "initial_value", value = "5"), @Parameter(name = "force_table_use", value = "true"), @Parameter(name = "table_name", value = "SEQ_TABLE"), @Parameter(name = "value_column_name", value = "VALUE_COL"), @Parameter(name = "segment_column_name", value = "KEY_COL"), @Parameter(name = "segment_value", value = "SCENARIO") }) The problem is, that hibernate generated sequence table (SEQ_TABLE in my case, generated using hbm2ddl) does not have a primary keys. How do I tell hibernate that I want to have the primary key for the sequence table set on KEY_COL ?

• updated validation example for web api

  - by MonkeyBonkey

  I tried the validation example code for web api on the latest mvc 4 download and I'm getting some errors. Does anyone have an updated example of the ValidationActionFilter class. Here's the original code public class ValidationActionFilter : ActionFilterAttribute { public override void OnActionExecuting(HttpActionContext context) { var modelState = context.ModelState; if (!modelState.IsValid) { dynamic errors = new JsonObject(); foreach (var key in modelState.Keys) { var state = modelState[key]; if (state.Errors.Any()) { errors[key] = state.Errors.First().ErrorMessage; } } context.Response = new HttpResponseMessage<JsonValue>(errors, HttpStatusCode.BadRequest); } } } I'm getting an error on HttpResponseMessage The non-generic type 'System.Net.Http.HttpResponseMessage' cannot be used with type arguments Also it looks like I need to add a Json reference, but should I be using JSON.net instead? An example of this using Json.net?

• How to make sure the value is reset in foreach loop in PHP

  - by kwokwai

  Hi all, I was writing a simple PHP page and a few foreach loops were used. Here are the scripts: $arrs = array("a", "b", "c"); foreach ($arrs as $arr) { if(substr($arr,0,1)=="b") { echo "This is b"; } } // ends of first foreach loop and I didn't use ifelse here And when this foreach ends, I wrote another foreach loop in which all the values in the foreach loop was the same as previous foreach. foreach ($arrs as $arr) { if(substr($arr,0,1)=="c") { echo "This is c"; } } I am not sure if it is a good practice to have two foreach loops with same values and keys. Will the values get overwritten in the first foreach loop?

• Need help on how to setup my packages and projects in eclipse

  - by jax

  I am new to Java and am making a license generator. This is my current setup. com.example.licensegenerator.client (used by the client application) :LicenseLoader (no Main method) :LicenseDownloader (no Main method) com.example.licensegenerator.server.keys (used by the server) :ProductKeyGenerator(Main method) com.example.licensegenerator.server.license (used on the server also) :LicenseGenerator(Main method) com.example.licensegenerator.lib (Shared classes between client and server) :Contants (no main) Now I have a few questions. Is it OK to have multiple Main() methods in a single project? Will I be able to compile them to different .jar files? (In this case I need two different jars for the server) Is there a better way to setup the packages? And a totally unrelated question, with exceptions, is it better to handle them right then and there or throw them and let the main method catch them all (the program cannot recover if an error occurs)

• Suggest Sphinx index scheme

  - by htf

  Hi. In a MySQL database I have documents of different type: some have text content, meta keys, descriptions, others have code, SKU number, size and brand name and so on. The problem is, I have to search something in all of these documents and then display a single page, where the results will be grouped by the document type, such as help page, blog post, item... It's not clear for me how to implement the Sphinx index: I want to have a single index to speed up queries, but since different docs have different structure - how can I group them? I was thinking about just concatenating them, but it just doesn't feel right.

• Sharepoint Document Upload Page - Passing URL Variables?

  - by Corey O.

  Throughout my SharePoint site, I have several document repositories that are tied to primary keys from an external database. I have added custom columns in the document library metadata fields so that we will know which SharePoint documents correspond with which table entries. As a requirement, we need to have document uploads that have these fields automatically populated. For instance, I'd like to have the following url: ./Upload.aspx?ClassID=2&SystemID=63 So that when you upload any documents to this library, it automatically adds the ClassID and SystemID values to the corresponding ClassID and SystemID columns outlined in the SharePoint document library fields. Is there any quick or easy way to do this, or will I have to completely rewrite the Upload.aspx script from scratch?

• Looking for a Silverlight 3 or 4 Menu control providing decent keyboard support.

  - by Geo

  I've an N-Tier application using Silverlight for the client. The customer as one particular request - I thought was more than reasonable: all actions – including menu navigation – has to be available through keyboard. When I tried Silverlight 4 I was surprised not to find any menu control so I downloaded several open source and commercial menu controls. I was very disappointed, after having searched for a couple of hours I didn’t manage to find any control that provide a decent keyboard support. Most controls provide no support or some basic support but not one control enabled to gain focus on the first item through the keyboard. You are able to use the keyboard (arrow keys) but you need first to select the control with the mouse! Not one control provided support for Keyboard shortcuts. Does anyone know of any Silverlight control providing descent support?

• How to delete a Dictionary row that is a Double by using an Int?

  - by Richard Reddy

  Hi, I have a Dictionary object that is formed using a double as its key values. It looks like this: Dictionary<double, ClassName> VariableName = new Dictionary<double, ClassName>(); For my project I have to have the key as the double as I require values like 1.1,1.2,2.1,2.2,etc in my system. Everything in my system works great except when I want to delete all the keys in a group eg all the 1 values would be 1.1,1.2, etc. I can delete rows if I know the full value of the key eg 1.1 but in my system I will only know the whole number. I tried to do the following but get an error: DictionaryVariable.Remove(j => Convert.ToInt16(j.Key) == rowToEdit).OrderByDescending(j => j.Key); Is there anyway to remove all rows per int value by converting the key? Thanks, Rich

• Unable to send an associative array in JSON format in Zend to client

  - by Anorflame

  Hi, In one of my actions in a controller, I'm using the json view helper to send back a response to an ajax request. On the client side I alert the data that is passed to the success callback function. It works fine as long as the response is a number or an array with default keys. Once I try to send an associative array, it alerts with [object Object]. Server code: $childArray = array('key'=>'value'); $this->_helper->json($childArray); javascript: function displayChildren(data){ alert(data); } ... $.ajax({ url: "/po/add", dataType: "json", data: {format: "json"}, success: displayChildren }); I have no idea what am I doing wrong here, so any help would be appreciated...

• ASP.NET: How to "reset" validation after calling Page_ClientValidate

  - by Josh Young

  I have an ASP.NET page with a jQuery dialog that is displayed to change some data. I am setting up the jQuery dialog so that when the user clicks the OK button it calls ASP.NET's Page_ClientValidate('validationGroup') via javascript, finds all the invalid controls and changes their CSS class. So here's the scenario: the user opens the dialog, keys in some invalid data, clicks OK (receiving the validation messages), and then clicks Cancel. Now the dialog is closed, but the validation messages are still there, so that when they open the dialog again, the data goes back to the way it was initially, but the form is still in the invalid state (the validation messages are still displaying). What I need is a "reset" function of sorts to call after calling Page_ClientValidate('validationGroup'). Does this exist?

• What is wrong with my SQL syntax for an UPDATE with a JOIN?

  - by Phil H

  I have two tables, related by a common key. So TableA has key AID and value Name and TableB has keys AID, BID and values Name, Value: AID Name 74 Alpha AID BID Name Value 74 4 Beta Brilliance I would like to update the TableB Value here from Brilliance to Barmy, using just the Name fields. I thought I could do it via an UPDATE containing a JOIN, but Access (I know...) is complaining with 'Syntax error (missing operator) in query expression ' and then everything from 'Barmy' here: UPDATE tB SET tB.BValue='Barmy' FROM TableB tB INNER JOIN TableA tA ON tB.AID=tA.AID WHERE tB.Name='Beta' AND tA.Name='Alpha'; What is my heinous crime? Or is it just Access not conforming?

• Using local configs in a Heroku deployment environment

  - by ambertch

  I'm trying to migrate my app to Heroku - I have a config file that varies with development/staging/production environments as it contains uniquely assigned keys (from Facebook, S3, etc.), so I keep it out of the repository and keep the configs local. As such I'm trying to find a solution for Heroku to have that config file since Heroku deploys from the repository. I noticed Heroku deploys from the master branch - can it deploy from another branch? Because then I could commit the Heroku configs there, and have it not overwrite the other environments' configs every time it pulls. Thanks!

• calling database driver in java app [basically a swing app]

  - by user993250

  I have made a java application that allows a user to choose from certain standards and then allows him to customize those standards according to his needs. Now, the customization [via a swing application] that has been made needs to be persistent. For this we use a database [mysql/access] and hook it to the application so that with each customization made, a table [if non-existent] is created [thus making it runtime and we can not pre-determine the table names or the keys of table etc] and an appropriate entry in the table is made. I have written the driver for this connection. How do I call it in the java application and what approach should I take? I would much appreciate that if somebody can refer me some example that not only shows a sample connection being made via driver but its appropriate calls to the database as well so that i can use it as a guide.

• How do you search through a map?

  - by Jack Null

  I have a map: Map<String, String> ht = new HashMap(); and I would like to know how to search through it and find anything matching a particular string. And if it is a match store it into an arraylist. The map contains strings like this: 1,2,3,4,5,5,5 and the matching string would be 5. So for I have this: String match = "5"; ArrayList<String> result = new ArrayList<String>(); Enumeration num= ht.keys(); while (num.hasMoreElements()) { String number = (String) num.nextElement(); if(number.equals(match)) { result.add(number); } }

• How to create unique user key

  - by Grayson Mitchell

  Scenario: I have a fairly generic table (Data), that has an identity column. The data in this table is grouped (lets say by city). The users need an identifier in order for printing on paper forms, etc. The users can only access their cites data, so if they use the identity column for this purpose they will see odd numbers (e.g. a 'New York' user might see 1,37,2028... as the listed keys. Idealy they would see 1,2,3... (or something similar) The problem of course is concurrency, this being a web application you can't just have something like: UserId = Select Count(*)+1 from Data Where City='New York' Has anyone come up with any cunning ways around this problem?

• What is the Sql Server equivalent for Oracle's DBMS_ASSERT?

  - by dotNetYum

  DBMS_ASSERT is one of the keys to prevent SQL injection attacks in Oracle. I tried a cursory search...is there any SQL Server 2005/2008 equivalent for this functionality? I am looking for a specific implementation that has a counterpart of all the respective Oracle package members of DBMS_ASSERT. NOOP SIMPLE_SQL_NAME QUALIFIED_SQL_NAME SCHEMA_NAME I know the best-practices of preventing injection...bind variables...being one of them. But,in this question I am specifically looking for a good way to sanitize input...in scenarios where bind-variables were not used. Do you have any specific implemetations? Is there a library that actually is a SQL Server Port of the Oracle package?

• Insert data into table effeciently, postgresql

  - by Rowan_Gaffney

  I am new to postgresql (and databases in general) and was hoping to get some pointers on improving the efficiency of the following statement. I am inserting data from one table to another, and do not want to insert duplicate values. I have a rid (unique identifier in each table) that are indexed and are Primary Keys. I am currently using the following statement: Insert INTO table1 SELECT * FROM table2 WHERE rid NOT IN (SELECT rid FROM table1). As of now the table one is 200,000 records, table2 is 20,000 records. Table1 is going to keep growing (probably to around 2,000,000) and table2 will stay around 20,000 records. As of now the statement takes about 15 minutes to run. I am concerned that as Table1 grows this is going to take way to long. Any suggestions?

• SEO URL Structure

  - by Neil

  Based on the following example URL structure: mysite.com/mypage.aspx?a=red&b=green&c=blue Pages in the application use ASP.net user controls and some of these controls build a query string. To prevent duplicate keys being created e.g. &pid=12&pid=10, I am researching methods of rewriting the URL: a) mysite.com/mypage.aspx/red/green/blue b) mysite.com/mypage.aspx?controlname=a,red|b,green|c,blue Pages using this structure would be publishing content that I would like to get indexed and ranked - articles and products (8,000 products to start, with thousands more being added later) My gut instinct tells me to go with the first method, but would it would be overkill to add all that infrastructure if the second method will accomplish my goal of getting pages indexed AND ranked. So my question, looking at the pro's and con's, Google Ranking, time to implement etc. which method should I use? Thanks!
