• Need help in filtering records based on radius value in solr

  - by kshama

  Hi, I am using solr with Lucene spatial 2.9.1 as per http://www.ibm.com/developerworks/java/library/j-spatial/ I want to write a query, that will retrieve records within a given radius using hsin function, and using cartesian tiers as filters. So i wrote query like this http://localhost:8983/solr/select/?q=body:engineering colleges^0 AND _val_:"recip(hsin(0.227486,1.354193 , lat_rad, lng_rad, 4), 1, 1, 0)"^100 &&fq={!tier x=13.033993 y=77.589569 radians=false dist=4 prefix=tier_ unit=m} My records include many US records and few Indian records. For US records filtering based on radius is working fine. But for Indian records its not varying even if i change the radius . So can any one tell me if anything is wrong with the query or is there any configuration issues related to solr in order to make this work, or since record density is very less for Indian records filtering is not happening properly.Am not able to figure it out. Thanks in advance.

• ggplot add percentage labels based on x-axis variables

  - by eugeneyan

  I've a ggplot that shows the counts of tweets for some brands as well as a label for the overall percentage. This was done with much help from this link: ggplot: showing % instead of counts in charts of categorical variables # plot ggplot of brands ggplot(data = test, aes(x = brand, fill = brand)) + geom_bar() + stat_bin(aes(label = sprintf("%.02f %%", ..count../sum(..count..)*100)), geom = 'text', vjust = -0.3) Next, I would like to plot it based on brand and sentiment, with the labels for the bars of each brand totalling up to 100%. However, I have difficulty amending my code to do this. Would you be able to help please? Also, would it be possible to change the colours for neu to blue and pos to green? # plot ggplot of brands and sentiment ggplot(data = test, aes(x = brand, fill = factor(sentiment))) + geom_bar(position = 'dodge') + stat_bin(aes(label = sprintf("%.02f %%", ..count../sum(..count..)*100)), geom = 'text', position = position_dodge(width = 0.9), vjust=-0.3)

• LINQ Multiple LIKE based on List

  - by Bathan

  I have a list of keywords in an ArrayList and I wanted to be able to build a query to find records in a table based on this keywords. Since the list of keywords is dynamic I cannot build a fixed query here. if I do something like this: foreach (string kw in keywords) { query = query.Where(p => p.Name.StartsWith(kw)); } The "StartsWith" is required here because I need to search those records that actually start with the provided keyword. In T-SQL it Would be something like this Select * from Table where Name like 'keyword1%' or Name like 'keyword2%' or Name like 'keyword3%' or ... But I need to be able to do this in LINQ...Is this possible?

• Slick PHP based image manager for managing user profile images

  - by franko75

  Hi, I'm just throwing this out there as I'm plodding my way through creating a Member Photo album on a site i'm working on, where they can login and upload their photos to a personal gallery. I want this to be nice and lightweight, but still slick and "modern" with a modal based interface for the user. I'm surprised though that there is seemingly nothing open source out there which fits the bill - I've done a few searches on Google to no avail and can't seem to find anything. Lots of bloated photo galleries out there but nothing looks like it has been developed using more recent technologies. Is anyone aware of anything which might suit what I'm looking for? I'm fully prepared to try and code it myself but I'd be delighted if I didn't have to! Pure laziness you might say, but there's no point reinventing the wheel.

• SharePoint form-based authentication problem with itemDeleting event?

  - by Clodin

  Hi! I have a SharePoint site (I'm the farm administrator with full control over the farm and site) and I used Windows authentication. I had a event receiver feature installed which manage add/update/delete for my lists to have custom behavior. Everything worked ok on Windows Authentication. But... now I am using form-based authentication (the same, I'm the site administrator with full control), but my feature works fine only with add/update events.... delete doesn't work any more, and it's the same code (damn it) as it was on windows authentication. Where am I doing wrong? why delete items don't work any more? Thanks in advance

• Create Class objects based on type signature

  - by Andreas_D

  Class.forName(boolean.class.getName()); This doesn't work in Java - the virtual machine slaps you with a ClassNotFoundException. I was in need for something like that because I wanted to reflect methods based on Strings that included the method signatures, like public void doSomething(boolean yesWeCan, java.lang.String[] presidents); At the end I came up with a custom 'ClassFactory' which translates the type Strings to class objects. This factory includes a lot of handlers for primitive and array type values. The handler for array type objects is something like: if (isArrayOfObjects) { return Class.forName("L["+typeName.replace("[]", "")+";"); } My question is - have I missed something in the Java 1.5+ API that might do the trick?

• Trying to create fields based on a case statement

  - by dido

  I'm having some trouble with the query below. I am trying to determine if the "category" field is A, B or C and then creating a field based on the category. That field would sum up payments field. But I'm running into error saying "incorrect syntax near keyword As". I am creating this in a SQL View. Using SQL Server 2008 SELECT r.id, r.category CASE WHEN r.category = 'A' then SUM(r.payment) As A_payments WHEN r.category = 'B' then SUM(r.payment) As B_payments WHEN r.category = 'C' then SUM(r.payment) As C_payments END FROM r_invoiceTable As r GROUP BY r.id, r.category I have data where all of the above cases should be executed because the data that I have has A,B and C Sample Data- r_invoiceTable Id --- Category ---- Payment 222 A ---- 50 444 A ---- 30 111 B ---- 90 777 C ---- 20 555 C ---- 40 Desired Output A_payments = 80, B_payments = 90, C_payments = 60

• starting a service based on someone's GPL/MIT licensed code

  - by fooyee

  someone wrote a nice framework for developing html5 3d engine. It's GPL/MIT licensed. Do you think it's a good idea to build upon it, and then repackage it and sell it as a service? For eg the framework lets you build 3d environments. so I build on it, maybe add a few features like characters and music in the environment, and turn it into an online game. Is it a feasible idea? Of course, part of the GPL license says that all source code has to be visible to end users. Assuming the web is a winner take all market based on first mover advantage, why care about hiding the source code? It's the product that's being sold that counts.

• Problem with session based login after moving relevent files to site root

  - by YsoL8

  Hello I have a site which I have been testing in a sub-folder of my clients site-root. I had no log in problems during testing, but then I moved the new site files from a sub-directory to the main site root, and now I'm losing my logged in state after almost every page refresh in secure areas. I am running a $_session based login system that refreshes the session id on every page load, with a comparison value stored in the MySQL database. Does anyone have suggestions for what could be causing this problem?

• Delay-Load equivalent in unix based systems

  - by saran

  What is the delay load equivalent in unix based system. I have a code foo.cpp, While compiling with gcc I link it to shared objects(totally three .so files are there.).Each of the .so file for different option. ./foo -v needs libversion.so ./foo -update needs libupdate.so I need the symbol for those libraries should be resolved only at the run time. ./foo -v should not break even if libupdate.so library is not there. It is working in windows using the delay load option(in properties of dll). What is its equivalent in unix systems. Will '-lazy' option does the same in UNIX?. If so,Where to include this option? (in makefile or with linker ld). I am not good in unix. Please help me.. Thanks in advance.

• Android card based game, need help to start

  - by user331296

  Hello, I'm just setting out in android development. I want to make a kind of card based game. I'm just looking for suggestions really on how I might start it. I know I have to make the menu layout and view, then use an Intent from that to get to the main game view. My sticking points are: -There's going to be a deck of cards. It's going to be a set number so I was thinking I could just have each card defined as a button in the layout. I don't know if that is the right way to do it though. -Storage of card details. I'm thinking of using an xml file to store these. Thanks in advance.

• Determine phone number based on time zone?

  - by Zachary Burt

  I have a (potentially international) phone number. It may or may not have a country code prefix. Does anyone know of a database that will help me map phone number = time zone? I would even just like to map phone number = country, since I can probably create country = time zone by scraping existing data on the web. This is a more complicated problem than it looks; for example, how do I know if it's a US-based number -- e.g. is it a USA area code, or an international country calling code? Any language is fine; I can port it.

• compiling boost based application using cron

  - by user303544

  Hi All, I am building some boost based application for various embedded targets. I have developed a script which can build my application with different toolchain for several targets. This script works fine when I run it from command line but if it is invoked from cron it always fails to link the object files. My application has dependency on openssl. Can anyone please give some idea? What would be the root cause of this kind of behavior? Thanks in advance.

• LRU LinkedHashMap that limits size based on available memory

  - by sanity

  I want to create a LinkedHashMap which will limit its size based on available memory (ie. when freeMemory + (maxMemory - allocatedMemory) gets below a certain threshold). This will be used as a form of cache, probably using "least recently used" as a caching strategy. My concern though is that allocatedMemory also includes (I assume) un-garbage collected data, and thus will over-estimate the amount of used memory. I'm concerned about the unintended consequences this might have. For example, the LinkedHashMap may keep deleting items because it thinks there isn't enough free memory, but the free memory doesn't increase because these deleted items aren't being garbage collected immediately. Does anyone have any experience with this type of thing? Is my concern warranted? If so, can anyone suggest a good approach? I should add that I also want to be able to "lock" the cache, basically saying "ok, from now on don't delete anything because of memory usage issues".

• Screenflow based application in Adobe Flex/Flash

  - by iceman

  I'm searching for some code samples for my Flash application. The app is based on screen-flows , i.e each screen is defined with some visual elements with some buttons which have async events associated with them(consuming web services basically). The buttons also have functionality to go back and forth between screens and jump to any screen. I want to define all of the visual elements and the functionality of the events in a XML file. Thus the model, view and controller are all in the XML. Does any framework allow this like Pure MVC? Where can I find some examples of this kind of functionality that I want?

• Converting table based layout into a div/css based one.

  - by nimo9367

  I'm supposed to rewrite the UI for a rather large web application. The thing is that the layout is completely based on tables and if I could somehow, semi automatically, convert the tables into divs it would save me a huge amount of time. What are the best practices when doing something like this? Is this a good idea at all? The application use layout files (containing something similar to helpers) that are parsed into html at runtime and the application itself also output html at specific places. So the work will consist of converting these helpers and the htmloutput code within the application.

• DOS Batch file - Copy file based on filename elements

  - by user1848356

  I need to sort alot of files based on their filename. I would like to use a batch file to do it. I do know what I want but I am not sure of the correct syntax. Example of filenames I work with: (They are all in the same directory originally) 2012_W34_Sales_Store001.pdf 2012_W34_Sales_Store002.pdf 2012_W34_Sales_Store003.pdf 2012_November_Sales_Store001.pdf 2012_November_Sales_Store002.pdf 2012_November_Sales_Store003.pdf I would like to extract the information that are located between the "_" signs and put them into a different variable each time. The lenght of the informations contained between the _ signs will be different everytime. Example: var1="2012" var2="W34" (or November) var3="Sales" var4="001" If I am able to do this, I could then copy the files to the appropriate directory using move %var1%_%var2%_%var3%_%var4%.pdf z:\%var3%\%var4%\%var1%\%var2% It would need to loop because I have Store001 to Store050. Also, there are not only Sales report, many others are available. I hope I am clear. Please help me realize this batchfile!

• Create categorial variable in R based on range

  - by Stedy

  I have a dataframe with a column of integers that I would like to use as a reference to make a new categorical variable. I want to divide the variable into three groups and set the ranges myself (ie 0-5, 6-10, etc). I tried cut but that divides the variable into groups based on a normal distribution and my data is right skewed. I have also tried to use if/then statements but this outputs a true/false value and I would like to keep my original variable. I am sure that there is a simple way to do this but I cannot seem to figure it out. Any advice on a simple way to do this quickly?

• WPF Databinding and Styling based on Data in an item in an IList

  - by Nate Bross

  I have a ListBox bound to a list of Items (for arguement, lets say its got a string and two dates Entered and Done). I would like to make the background color of items in the ListBox have a gray color if the Done DateTime is != DateTime.MinValue. Edit: Should I make a converter? and convert DateTime to a Brush based on the value of the DateTime? Is something like this my best option? or is there a simple Xaml snippet I could use? [ValueConversion(typeof(DateTime), typeof(Brush))] class MyConverter : IValueConverter { ... }

• Django - Expression based model constraints

  - by rtmie

  Is it possible to set an expression based constraint on a django model object, e.g. If I want to impose a constraint where an owner can have only one widget of a given type that is not in an expired state, but can have as many others as long as they are expired. Obviously I can do this by overriding the save method, but I am wondering if it can be done by setting constraints, e.g. some derivative of the unique_together constraint WIDGET_STATE_CHOICES = ( ('NEW', 'NEW'), ('ACTIVE', 'ACTIVE'), ('EXPIRED', 'EXPIRED') ) class MyWidget(models.Model): owner = models.CharField(max_length=64) widget_type = models.CharField(max_length = 10) widget_state = models.CharField(max_length = 10, choices = WIDGET_STATE_CHOICES) #I'd like to be able to do something like class Meta: unique_together = (("owner","widget_type","widget_state" != 'EXPIRED')

• INSERT 0..n records into table 'A' based on content of table 'B' in MySql 5

  - by Robert Gowland

  Using MySql 5, I have a task where I need to update one table based on the contents of another table. For example, I need to add 'A1' to table 'A' if table 'B' contains 'B1'. I need to add 'A2a' and 'A2b' to table 'A' if table 'B' contains 'B2', etc.. In our case, the value in table 'B' we're interested is an enum. Right now I have a stored procedure containing a series of statements like: INSERT INTO A SELECT 'A1' FROM B WHERE B.Value = 'B1'; --Repeat for 'B2' -> 'A2a'; 'B2' -> 'A2b'; 'B3' -> 'A3', etc... Is there a nicer more DRY way of accomplishing this? Edit: There may be values in table 'B' that have no equivalent value for table 'A'.

• Make a <div> square when there is a dynamically changing width based on percentage

  - by Nate

  I am working on a web app that will generate an NxN grid based on the user's selection of N. I want the total width of the grid to be relative (ie 100% of the available space) so that users can print on various paper sizes. I can easily calculate the width of the squares in the grid by % (ie: 100%/N), but I am having issues calculating the height. The height of a web page is always going to be infinite unless I artificially limit it which, like I said, I don't want to do. How can I make the squares in my grid be square versus rectangular when the height and width constraints of my grid are dynamic and not square? Thanks in advance!
