  • .Net friendly, local, key-value pair, replicatable datastore

    - by Brad Mathews
    I am looking for a key/value type datastore with very specific requirements. Anyone know anything that will work? Needs to be a component of some sort. No additional installation needed. The datastore needs to be on the local hard drive. I am using VB.Net for a desktop app running Windows XP through 7 so it needs to callable by that environment. It needs to replicatable. If I have four copies of my app running on the network, each local copy of the datastore needs to replicate with the others. As close to real time as possible. The first three are easy, I can do that with ADO.Net out of the box. The last one, replication, is the one I do not have answer to. Does such an animal exist? Thanks, Brad

  • How can I best geocode a table of addresses in SQL Server?

    - by ess
    I've got a SQL Server 2008 table with addresses. I've got some C# code that can individually geocode the addresses. I've got a Google Maps API for geocoding. Now I'm trying to figure out the most efficient way to use these resources. I could write a console app that manually updates the tables using my C# library, but the data I have is updated periodically. I will be performing an import routine of some sort and I'm thinking it would be 'simplest' to perform the geocoding as the import occurs. I'm not so strong on SQL Server capabilities, so I'm looking for advice. I've considered letting the import call an assembly I create that would be referenced in SQL Server, but read that Sql Server 2008 has made it virtually impossible to reference your own DLL. So my next guess is having the import call a web service to pass in the address and update the table with the results, but I've not had much luck in finding info on this method. Any advice?

  • Why is the same input returning two different MD5 hashes?

    - by Rob
    Alright, I have two files. They are the EXACT SAME. The first file is: http://iadsonline.com/servconfig.php And the second file is: http://xzerox.info/servconfig.php However, when I use md5_file() to get their MD5, They return two different MD5's. The first returns cc7819055cde3194bb3b136bad5cf58d, which is incorrect, and the second returns 96a0cec80eb773687ca28840ecc67ca1, which is correct. The file is simply an &nbsp; To verify, I've used this code: $contents = file_get_contents($URL); echo htmlentities($contents); And they both return &nbsp; So why is it hashing them differently?

  • Is Rails default CSRF protection insecure

    - by schickb
    By default the form post CSRF protection in Rails creates an authenticity token for a user that only changes when the user's session changes. One of our customers did a security audit of our site and flagged that as an issue. The auditor's statement was that if we also had a XSS vulnerability that an attacker could grab another user's authenticity token and make use of it for CSRF attacks until the user's session expired. But is seems to me that if we had an XSS vulnerability like that an attacker could just as easily grab another user's session cookie and login as that user directly. Or even just make call to our REST Api as the user being attacked. No secondary CSRF attack needed. Have I missed something? Is there a real problem with the default CSRF protection in Rails?

  • Bug in the official Android Fragments training sample?

    - by Jeff Axelrod
    It seems to me that there must be a bug in the Android Fragments demo. As background, Fragments are apparently sometimes instantiated by the Android OS and thus need a public no-arg constructor: All subclasses of Fragment must include a public empty constructor. The framework will often re-instantiate a fragment class when needed, in particular during state restore, and needs to be able to find this constructor to instantiate it. If the empty constructor is not available, a runtime exception will occur in some cases during state restore. But the NewsReader demo from the official Android training on Fragments constructs the HeadlinesFragment class and configures it with setOnHeadlineSelectedListener(this) from NewsReaderActivity.onCreate(). If the Android OS re-instantiates this fragment, the mHeadlineSelectedListener field will be null because HeadlinesFragment doesn't save or restore its state. Is this a bug or am I missing something?

  • How to occupy all the space in a div when working with min-height header / footer

    - by javacoder
    I believe this is a beginner's CSS question. I am utilizing the method described in http://www.xs4all.nl/~peterned/examples/csslayout1.html to fix a header to the top and a footer to the bottom. What I'd like to achieve now is two columns inside the content div. A left one of 200px and a right one that takes up the rest of the width. Unfortunately, I can't get the left and right divs to display correctly: they just don't grow vertically, and if I make the right div "width: 100%" it positions itself underneath the left one. What is the trick to make the left and right div take up all the space within the content div? The layout1.css is the original one. I just added two entries: #left and #right layout1.css: /** * 100% height layout with header and footer * ---------------------------------------------- * Feel free to copy/use/change/improve */ html,body { margin: 0; padding: 0; height: 100%; /* needed for container min-height */ background: gray; font-family: arial, sans-serif; font-size: small; color: #666; } h1 { font: 1.5em georgia, serif; margin: 0.5em 0; } h2 { font: 1.25em georgia, serif; margin: 0 0 0.5em; } h1,h2,a { color: orange; } p { line-height: 1.5; margin: 0 0 1em; } div#container { position: relative; /* needed for footer positioning*/ margin: 0 auto; /* center, not in IE5 */ width: 750px; background: #f0f0f0; height: auto !important; /* real browsers */ height: 100%; /* IE6: treaded as min-height*/ min-height: 100%; /* real browsers */ } div#header { padding: 1em; background: #ddd url("../csslayout.gif") 98% 10px no-repeat; border-bottom: 6px double gray; } div#header p { font-style: italic; font-size: 1.1em; margin: 0; } div#content { padding: 1em 1em 5em; /* bottom padding for footer */ } div#content p { text-align: justify; padding: 0 1em; } div#footer { position: absolute; width: 100%; bottom: 0; /* stick to bottom */ background: #ddd; border-top: 6px double gray; } div#footer p { padding: 1em; margin: 0; } // added the following: div#left { border: 1px solid red; width: 200px; float: left; min-height: 100%; height: 100%; padding-left: 10px; margin-right: 10px; } div#right { border: 1px solid blue; float: left; min-height: 100%; height: 100%; padding-left: 10px; margin-right: 10px; } layout.html: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <title>CSS Layout - 100% height</title> <link rel="stylesheet" type="text/css" href="layout1.css" /> </head> <body> <div id="container"> <div id="header"> <h1>header</h1> </div> <div id="content"> <div id="left"> left column </div> <div id="right"> right column </div> </div> <div id="footer"> <p> footer </p> </div> </div> </body>

    Hello guys, I'm stuck here with this IE6 issue.. always a pain. So I'm using jQuery's "live" feature to add a product each time.

  • R: ggplot2, how to add a number of layers to a plot at once to reduce code

    - by John
    library(ggplot2) This code produces a nice looking plot: qplot(cty, hwy, data = mpg, colour = displ) + scale_y_log2() + labs(x="x axis") + labs(y="y axis") + opts(title = "my title") But I want to setup variables to try and to reduce code repetition: log_scale <- scale_y_log2() xscale <- labs(x="x axis") yscale <- labs(y="y axis") title <- opts(title = "my title") my_scales <- c(log_scale, xscale, yscale, title) # make a variable to hold the scale info changes above So that I can do this and add a bunch of things at the same time: qplot(cty, hwy, data = mpg, colour = displ) + my_scales # add these to your plot. but I get this error: Error in object$class : $ operator is invalid for atomic vectors I realize that the things going into my_scales need to be layers / different types of objects, but I don't see what they should be.

  • SharePoint 2010 Licensing Costs

    - by Franklin
    Hi, We will be implementing a public-facing website in SharePoint 2010 and I have a few questions regarding licensing: Is there any (relatively) reliable pricing information available for SharePoint 2010? What about rumors? What edition of SharePoint 2010 would be appropriate for a publicly facing website (in 2007, you needed Enterprise for this, but it seems that WCM functionality is included in Standard in 2010)? What would be a reasonable number to budget for SharePoint 2010 licensing for a publicly facing website? Thanks in advance for your help!

  • Rails - how can I query the db w/o touching the sessions table

    - by sa125
    Hi - I'm trying to provide a HTTP api to my app that queries a db that's read-only (for replication purposes). I find that my app crashes repeatedly when making a request b/c the call is trying to update the sessions table whenever I query the db. This doesn't happen when I return some text without hitting the database for info. class APIController < AplicationController def view data = Product.find(params[:id]).to_json # will fail data = { :one => 1, :two => 2 }.to_json # will succeed respond_to do |format| format.html { render :json => data } end end end How do I restrict it from touching the sessions table on this request (it's currently issuing an UPDATE on the updated_at field for that session). thanks.

  • WPF databinding update comboxbox2 based on selection change in combobox1 with MVVM

    - by cody
    I have a combo box that I have bound to a list that exists in my viewmodel. Now when a users makes a selection in that combo box I want a second combo box to update its content. So, for example, combobox1 is States and combobox2 should contain only the Zipcodes of that state. But in my case I don't have a predefined lists before hand for combobox2, I need to go fetch from a db. Also, if needed, I could get all the potential values for combobox2 (for each combobox1 value) before hand, but I'd like to avoiding that if I can. How do I implement in WPF and using MVVM? I'm fairly new to this whole wpf\databinding\mvvm world.

  • Options for keeping models and the UI in sync (in a desktop application context)

    - by Benju
    In my experience I have only had 2 patterns work for large-scale desktop application development when trying to keep the model and UI in sync. 1-An eventbus approach via a shared eventbus command objects are fired (ie:UserDemographicsUpdatedEvent) and have various parts of the UI update if they are bound to the same user object updated in this event. 2-Attempt to bind the UI directly to the model adding listeners to the model itself as needed. I find this approach rather clunky as it pollutes the domain model. Does anybody have other suggestions? In a web application with something like JSP binding to the model is easy as you ussually only care about the state of the model at the time your request comes in, not so in a desktop type application. Any ideas?

  • How do I use LDAP proxy user authentication from .net?

    - by DN
    I have a .net web application that uses simple bind to query the LDAP. The application uses integrated windows authentication. Do you have any recommendations on which option to use to authenticate against the LDAP: 1. simple LDAP bind using the logged in user's credentials 2. simple LDAP bind using a service account created for the application's use 3. LDAP proxy user authentication - I dont have enough info about this, so i'd be grateful if someone could explain it's benefit, recommended use and sample .net code to do the query.

  • What happens when auto_increment on integer column reaches the max_value in databases?

    - by Sanoj
    I am implementing a database application and I will use both JavaDB and MySQL as database. I have an ID column in my tables that has integer as type and I use the databases auto_increment-function for the value. But what happens when I get more than 2 (or 4) billion posts and integer is not enough? Is the integer overflowed and continues or is an exception thrown that I can handle? Yes, I could change to long as datatype, but how do I check when that is needed? And I think there is problem with getting the last_inserted_id()-functions if I use long as datatype for the ID-column.

  • Memory cleanup on returned array from static method (objective-c)

    - by Michael Bordelon
    In objective-c, I have a utility class with a bunch of static methods that I call for various tasks. As an example, I have one method that returns an NSArray that I allocate in the static method. If I set the NSArray to autorelease, then some time later, the NSArray in my calling method (that is assigned to the returned pointer) losses it's reference because the original form the static method is cleaned up. I can't release the NSArray object in the static method because it needs to be around for the return and assignment. What is the right way to return an object (like the NSArray) from a static class, and have it hang around for the calling class, but then get cleaned up later when it is no longer needed? Do I have to create the object first in the caller and pass in a pointer to the object and then return that same object form the static method? I know this is a basic O-O problem, I just never had this issue in Java and I do not do much C/C++. Thanks for your help.

  • Restlet/Jackson works differently when object implements Serializable

    - by ravyoli
    I am sending an object with some primitive fields using Restlet with Jackson converter. Up until now it worked great. But then I needed my object to implement Serializable, because I need to store it in memcache of GAE. For some reason - when the class implements Serializable, things stop working. Restlet sends a different string representation from before, and I can't even print that string in the server. I tried printing its byte value, char-by-char and the first numbers are: 0xfffd 0xfffd 0x0000 0x0005 0x0073 0x0072 Thanks a lot!

  • Nexus: removing repository

    - by David
    Hi, I accidently removed a hosted snapshot repository from Nexus containing a few artifacts needed by other developers on my team. Fine, I'll be able to recreate it fairly easy, but when I tried to add the repository again with the same name as the one I removed, the "Upload Artifact" tab did not show. I tried to clean the cache and reindex the public and public snapshot repos, but that didn't help. I also tried setting an alternative storage path by entering an alternative path on "Override Local Storage Location", same result. Will I have to create a brand new repository with a different name and change all repository reference in my projects? Thanks, David

My regular alt-shift just won't change the language (I even downloaded the last alpha version, which was supposed to solve the problem, but it didn't). So I'm looking for another latex editor for windows that will let me write Hebrew. Please advice. Note: I know that it is possible with Lyx, but I prefer a real Latex editor.

  • NHibernate Criteria - How to filter on combination of properties

    - by DavGarcia
    I needed to filter a list of results using the combination of two properties. A plain SQL statement would look like this: SELECT TOP 10 * FROM Person WHERE FirstName + ' ' + LastName LIKE '%' + @Term + '%' The ICriteria in NHibernate that I ended up using was: ICriteria criteria = Session.CreateCriteria(typeof(Person)); criteria.Add(Expression.Sql( "FirstName + ' ' + LastName LIKE ?", "%" + term + "%", NHibernateUtil.String)); criteria.SetMaxResults(10); It works perfectly, but I'm not sure if it is the ideal solution since I'm still learning about NHibernate's Criteria API. What are the recommended alternatives? Is there something besides Expression.Sql that would perform the same operation? I tried Expression.Like but couldn't figure out how to combine the first and last names. Should I map a FullName property to the formula "FirstName + ' ' + LastName" in the mapping class? Should I create a read only FullName property on the domain object then map it to a column?
