  • Passing JSON through the URI

    - by Leaf
    I'm trying to create a REST based web service with data encapsulated using JSON. My problem is when I pass the string version of JSON in the URI it turns to something like this: %7B%22coal%22:100,%22ele%22:1500.1%7D. I'm wondering if there are any functions Java for converting between the escaped and unescaped versions so I can parse the string.

  • What license do I need to use gSOAP in a commercial product?

    - by Lawrence Johnston
    I'd like to use gSOAP in a product which will be distributed commercially. The use I have in mind is what I suspect is a pretty typical workflow—generating a header using wsdl2h, consuming the header with soapcpp2, and then calling the functions generated in the stub in my code. I'm not 100 percent sure which license(s) I need to use to be able to do this. Has anybody here already gone through this and figured out the solution?

  • R: Plotting a graph with different colors of points based on advanced criteria

    - by balconydoor
    What I would like to do is a plot (using ggplot), where the x axis represent years which have a different colour for the last three years in the plot than the rest. The last three years should also meet a certain criteria and based on this the last three years can either be red or green. The criteria is that the mean of the last three years should be less (making it green) or more (making it red) than the 66%-percentile of the remaining years. So far I have made two different functions calculating the last three year mean: LYM3 <- function (x) { LYM3 <- tail(x,3) mean(LYM3$Data,na.rm=T) } And the 66%-percentile for the remaining: perc66 <- function(x) { percentile <- head(x,-3) quantile(percentile$Data, .66, names=F,na.rm=T) } Here are two sets of data that can be used in the calculations (plots), the first which is an example from my real data where LYM3(df1) < perc66(df1) and the second is just made up data where LYM3 perc66. df1<- data.frame(Year=c(1979:2010), Data=c(347261.87, 145071.29, 110181.93, 183016.71, 210995.67, 205207.33, 103291.78, 247182.10, 152894.45, 170771.50, 206534.55, 287770.86, 223832.43, 297542.86, 267343.54, 475485.47, 224575.08, 147607.81, 171732.38, 126818.10, 165801.08, 136921.58, 136947.63, 83428.05, 144295.87, 68566.23, 59943.05, 49909.08, 52149.11, 117627.75, 132127.79, 130463.80)) df2 <- data.frame(Year=c(1979:2010), Data=c(sample(50,29,replace=T),75,75,75)) Here’s my code for my plot so far: plot <- ggplot(df1, aes(x=Year, y=Data)) + theme_bw() + geom_point(size=3, aes(colour=ifelse(df1$Year<2008, "black",ifelse(LYM3(df1) < perc66(df1),"green","red")))) + geom_line() + scale_x_continuous(breaks=c(1980,1985,1990,1995,2000,2005,2010), limits=c(1978,2011)) plot As you notice it doesn’t really do what I want it to do. The only thing it does seem to do is that it turns the years before 2008 into one level and those after into another one and base the point colour off these two levels. Since I don’t want this year to be stationary either, I made another tiny function: fun3 <- function(x) { df <- subset(x, Year==(max(Year)-2)) df$Year } So the previous code would have the same effect as: geom_point(size=3, aes(colour=ifelse(df1$Year<fun3(df1), "black","red"))) But it still does not care about my colours. Why does it make the years into levels? And how come an ifelse function doesn’t work within another one in this case? How would it be possible to the arguments to do what I like? I realise this might be a bit messy, asking for a lot at the same time, but I hope my description is pretty clear. It would be helpful if someone could at least point me in the right direction. I tried to put the code for the plot into a function as well so I wouldn’t have to change the data frame at all functions within the plot, but I can’t get it to work. Thank you!

  • Flex DataGrid not Displaying Data

    - by asawilliams
    I have a custom dataGrid that acts more like a 2D list (if that makes sense at all). I am dynamically creating the columns and recreating the dataProvider to suit my needs. While debugging I can see that I am creating the columns and setting them to the dataGrid and creating and setting the dataProvider, but for some reason I am able to see the dataGrid and the columns but not the data. [Bindable] private var mockData:ArrayCollection = new ArrayCollection([ {value: "425341*"}, {value: "425341*"}, {value: "425341*"}, {value: "425341*"}, {value: "425341*"}, {value: "425341*"}, {value: "425341*"}, {value: "425341*"}, {value: "425341*"}]); ... <TwoDimensionalList width="100%" height="100%" numColumns="7" numRows="7" dataField="value" dataProvider="{mockData}"/> The snippet of code from the object only contains the important functions, everything else is not important (getters, setters, etc ...). While debugging I checked all the variables in the functions to make sure they were assigned and a value that I was expecting. [Snippet] public class TwoDimensionalList extends DataGrid { ... /** * Creates and sets properties of columns */ private function createColumns():void { var column:DataGridColumn; var cols:Array = this.columns; for(var i:uint=0; i < numColumns; i++) { column = new DataGridColumn("column"+i.toString()); column.dataField = "column"+i.toString(); cols[i]=column; } this.columns = cols; // go to the current gotoPage(this._currentPageNum); } /** * Sets the data for the dataprovider based on the * number of columns, rows, and page number. * * @param pageNum the page number of the data to be viewed in the DataGrids. */ private function gotoPage(pageNum:uint):void { _currentPageNum = pageNum; var startIndex:uint = (pageNum-1)*numColumns*numRows; var data:ArrayCollection = new ArrayCollection(); for(var i:uint=0; i < numRows; i++) { var obj:Object = new Object(); for(var j:uint=0; j < numColumns; j++) { if((i+(j*numRows)+startIndex) < _dataProvider.length) obj["column"+j.toString()] = String(_dataProvider.getItemAt(i+(j*numRows)+startIndex)["value"]); } data.addItem(obj); } this.dataProvider = data; } }

  • Where does abort() and terminate() "live"?

    - by user325016
    Regarding the terminate handler, As i understand it, when something bad happens in code, for example when we dont catch an exception, terminate() is called, which in turn calls abort() set_terminate(my_function) allows us to get terminate() to call a user specified function my_terminate. my question is: where do these functions "live" they don't seem to be a part of the language, but work as if they are present in every single cpp file, without having to include any header file.

  • Use a Datamodule in a Service Application

    - by O Engenheiro
    I wrote my Win32 App to test and debug. I've created a datamodule with all functionality needed to run the TCP sockets and IBDatabase components. After successfully testing the Datamodule in the Win32 application environment I am trying to hook the Datamodule into a Service Application template that I created, I can get nowhere in getting it to run. Could someone indicate whether this strategy of using a Datamodule with Component functionality encapsulating the primary service functions is workable and give a simple template example of how to hook it up if it is??

  • jQuery each doesn't have a callback-possibility?

    Hello I have a loop created with each, check this example: $('.foo').each(function(i){ //do stuff }); Is there any possibility to run a functions when this loop has ended? Couldn't find it on docs or Google. I can make it work without this kind of solution, but it's always good to search for and use the simpliest methods. Martti Laine

  • PHP Filesystem Pagination

    - by Byron
    How does one paginate a large listing of files within a folder? I can't see any functions in the PHP documentation that mention any way to specify an 'offset'. Both glob() and scandir() simply return all the files in the folder, and I'm afraid that won't be a good idea for a huge directory. Is there any better way of doing this than simply going through all the files and chopping off the first X number of files?

  • How to create a named temporary file in memory?

    - by conradlee
    I would like to use Python's tempfile module to create a temporary file that I will use for communication between processes (use of pipes is awkward). The documentation I've linked to above shows two functions that almost do what I want: tempfile.NamedTemporaryFile # For creating named tempfiles tempfile.SpooledTemporaryFile # For creating tempfiles in memory but actually I want a tempfile that is both named AND in memory. Any ideas?

  • PHP: Where to place return 'false' value?

    - by Mike
    Is one of the following functions better than the other, in terms of where to place the 'return false' statement? Function #1: function equalToTwo($a, $b) { $c = $a + $b; if($c == 2) { return true; } return false; } Function #2: function equalToTwo($a, $b) { $c = $a + $b; if($c == 2) { return true; } else { return false; } } Thanks!

  • Apache Balancing by source IP

    - by Daniel
    I am using Apache's Proxy Balancer to balance one sub domain (e.g. subdomain.domain.com) to an application which is located on 2 servers. Here an extract from my Apache configuration file: <Proxy *> Order deny,allow Allow from all </Proxy> <Proxy balancer://cluster1> BalancerMember http://server1:28081 route=w1 BalancerMember http://server2:28082 route=w2 </Proxy> ProxyPass /path balancer://cluster1/path ProxyPassReverse /path balancer://cluster1/path My question is, if it's possible to decide with the source IP-address which BalancerMember should be used for the request? To e.g. Requests from 1.2.3.4 to Member 1?

  • Delphi 6: How to search a dynamic array for sub-string quickly?

    - by Robert Oschler
    How can I search a dynamic array of char in Delphi 6 for a sub-string and get back an index to a match, not a pointer? I've seen functions in Delphi 6 that do this for strings but not for dynamic char arrays. There is a function called SearchBuf but that function returns a PChar pointer to the match location when what I need is the array index of the match. Thanks.

  • The Best Way to shred XML data into SQL Server database columns

    - by eddiegroves
    What is the best way to shred XML data into various database columns? So far I have mainly been using the nodes and value functions like so: INSERT INTO some_table (column1, column2, column3) SELECT Rows.n.value('(@column1)[1]', 'varchar(20)'), Rows.n.value('(@column2)[1]', 'nvarchar(100)'), Rows.n.value('(@column3)[1]', 'int'), FROM @xml.nodes('//Rows') Rows(n) However I find that this is getting very slow for even moderate size xml data.

  • overloading new/delete problem

    - by hidayat
    This is my scenario, Im trying to overload new and delete globally. I have written my allocator class in a file called allocator.h. And what I am trying to achieve is that if a file is including this header file, my version of new and delete should be used. So in a header file "allocator.h" i have declared the two functions extern void* operator new(std::size_t size); extern void operator delete(void *p, std::size_t size); I the same header file I have a class that does all the allocator stuff, class SmallObjAllocator { ... }; I want to call this class from the new and delete functions and I would like the class to be static, so I have done this: template<unsigned dummy> struct My_SmallObjectAllocatorImpl { static SmallObjAllocator myAlloc; }; template<unsigned dummy> SmallObjAllocator My_SmallObjectAllocatorImpl<dummy>::myAlloc(DEFAULT_CHUNK_SIZE, MAX_OBJ_SIZE); typedef My_SmallObjectAllocatorImpl<0> My_SmallObjectAllocator; and in the cpp file it looks like this: allocator.cc void* operator new(std::size_t size) { std::cout << "using my new" << std::endl; if(size > MAX_OBJ_SIZE) return malloc(size); else return My_SmallObjectAllocator::myAlloc.allocate(size); } void operator delete(void *p, std::size_t size) { if(size > MAX_OBJ_SIZE) free(p); else My_SmallObjectAllocator::myAlloc.deallocate(p, size); } The problem is when I try to call the constructor for the class SmallObjAllocator which is a static object. For some reason the compiler are calling my overloaded function new when initializing it. So it then tries to use My_SmallObjectAllocator::myAlloc.deallocate(p, size); which is not defined so the program crashes. So why are the compiler calling new when I define a static object? and how can I solve it?

  • MySQL - Calculate the net time difference between two date-times while excluding breaks?

    - by John M
    In a MySQL query I am using the timediff/time_to_sec functions to calculate the total minutes between two date-times. For example: 2010-03-23 10:00:00 - 2010-03-23 08:00:00 = 120 minutes What I would like to do is exclude any breaks that occur during the selected time range. For example: 2010-03-23 10:00:00 - 2010-03-23 08:00:00 - (break 08:55:00 to 09:10:00) = 105 minutes Is there a good method to do this without resorting to a long list of nested IF statements?

  • Samba domain trust errors on a specific interface

    - by John K
    We have a windows domain that also has RHEL member servers in it. All the servers have a primary network connection to the LAN, but some servers also have private dedicated links to one of our RHEL servers, which serves as a head to our SAN storage. This particular server is running Samba 3.5.15, and is running in domain authentication mode. Users can access shares on this server without a problem over the LAN connection from our Windows servers, but if a user tries to access the shares over a private link (i.e. a 192.168.1.2 address to the RHEL server) users get an error "The trust relationship between this workstation and the primary domain failed."

What I want to accomplish: After my nightly build I want to complete some profiling (instrumental) to see if some functions (will most likely always be the same) have changed in some negative way (or positive of course).
