  • Is there an extensible SQL like query language that is safe for exposing via a public API?

    - by Lokkju
    I want to expose some spatial (and a few non-spatial) datasets via a public API. The backend store will either be PostgreSQL/PostGIS, sqlite/spatialite, or CouchDB/GeoCouch. My goal is to find a some, preferably standard, way to allow people to make complex spatial queries against the data. I would like it to be a simple GET based request. The idea is to allow safe SQL type queries, without allowing unsafe ones. I would rather modify something that is off the shelf than doing the entire thing myself. I specifically want to support requesting specific fields from a table; joining results; and spatial functions that are already implemented by the underlying datastore. Ideas anyone?

  • cygwin slow file open

    - by Erdem
    My application uses fopen to open a lot of files. While in linux opening and reading thousand of files doesn't even take a second; in cygwin it takes more than 5 seconds. I think it is because path conversion functions in cygwin dlls. 'open' function is a bit faster. If I use -mno-cygwin it becomes very fast but I can't use it. Is there an easy way to make cygwin dlls just open files; without any linux-windows conversion?

  • PHP/Cronjob: What is my Cronjobs problem?

    - by Marius
    Hello there, I have no idea whats going on. But I have a script that looks like this. Cron job refuses to run it: include_once 'class_lib/mime_mail/mimeDecode.php'; include_once 'class_lib/Mail/IMAPv2.php'; include_once 'inc-functions.php'; include_once "$_SERVER[DOCUMENT_ROOT]/class_lib/DbFuctioneer.php"; $dbFuctioneer = new DbFuctioneer(); Everything works well when I remove: $dbFuctioneer = new DbFuctioneer(); Even when DbFuctioneer() looks like this: <?php class DbFuctioneer { function dbCountMatches( $count) { return $count; } } Does Cron have a problem with Classes in his Jobs? Thank you for your time. Kind regards, Marius

  • Program for HID USB Scale

    - by Alex
    Hi guys, I'm looking for a program that can read the weight on a USB scale, namely the Pelouze 10lb USB Portable Scale. I thought it would have a virtual COM port driver but instead, it uses HID drivers. I've been searching for a whole month for a program that can help me transfer the reading of the scale to Microsoft Excel. Can someone help me out or point me in the right direction? I am absolutely illiterate to programming. Much gratitude any help given.

  • Inverse Logistic Function / Reverse Sigmoid Function

    - by Chanq
    I am currently coding up a fuzzy logic library in java. I have found the equations for all the standard functions - Grade, inverseGrade, Triangle, Trapezoid, Gaussian. However, I can't find the inverse of the sigmoid/ logistic function. The way I have written the logistic function is java is : //f(x) = 1/(1+e(-x)) public double logistic(double x){ return (1/(1+(Math.exp(-x))); } But I can't work out or find the inverse anywhere. My algebraic/calculus abilities are fairly limited, hence why I haven't been able to work out the inverse of the function. Any hints or pointers would be a big help. Thanks

  • textbox supplied route values with javaScript

    - by Maslow
    I've tried the bare method and the T4MVC method but so far both are routing me to the current URL instead of the default path with no arguments for the following action: public virtual ActionResult Index(byte? location, int? sublocation) { } So when I try Url.Action("Index","Locations", new {location="", system=""}) if I'm at a location already this method returns the path to where I'm already at instead of the default path with no arguments. As does the following method with T4MVC. <input type="button" value="Go" style="display:none" onclick="window.location='<%= Url.Action(MVC.Controller.Index()) %>/'+$('input#location').val()+'/'+$('input#sublocation').val()+'/';" /> How can I get the default route with no arguments?

  • Pass elements of a list as arguments to a function in python

    - by Wilduck
    I'm building a simple interpreter in python and I'm having trouble handling differing numbers of arguments to my functions. My current method is to get a list of the commands/arguments as follows. args = str(raw_input('>> ')).split() com = args.pop(0) Then to execute com, I check to see if it is in my dictionary of command- code mappings and if it is I call the function I have stored there. For a command with no arguments, this would look like: commands[com]() However, if a command had multiple arguments, I would want this: commands[com](args[0],args[1]) Is there some trick where I could pass some (or all) of the elements of my arg list to the function that I'm trying to call? Or is there a better way of implementing this without having to use python's cmd class?

  • Convert Double to String without precision loss in javascript

    - by holger
    I would like to convert a floating point variable to a string without losing any precision. I.e. I would like the string to have the same information as my floating point variable contains, since I use the output for further processing (even if it means that the string will be very long and readable). To put this more clearly, I would like to have functions for cyclic conversion var dA = 323423.23423423e4; var sA = toString(dA); var dnA = toDouble(sA); and I would like dnA and dA to be equal Thanks PS: Sources on the internet usually talk about how to round strings but I have not found information on exact representation. Also I am not interested in Arbitrary Precision calculations, I just need double precision floating point arithmetic.

  • NSIS Installer - Displaying different licences

    - by Wysawyg
    Heya, I'm trying to modify an existing NSIS install script to allow for different licence files to be presented to the user depending on whether they are a new or existing user. I have pre-existing code which detects an existing install in the .onInit section. However I'm running into bumps trying to use the NSIS provided licence screen e.g. !InsertMacro MUI_PAGE_LICENSE Content\Licence.rtf I would like to be able to choose between Licence and Licence2.rtf (though they'll be renamed something representative in the final version). I've tried using selectable sections calling functions which nest the !insertmacro but that doesn't work because it needs to be in the base level of the script. I can't change the parameter to be runtime definable because it needs to know what the file is at compile time to build it into the installer. I know I can roll my own custom page called from a function and do it that way but I was wondering if anyone had got the NSIS installer working with using the MUI_PAGE_LICENSE and different licences. Thanks

  • php encrypting an integer to get only alphanumeric characters?

    - by Matthew Steiner
    When I use some of php's encryption functions, I end up getting a few characters I don't want (+, /, =). The problem is that my application doesn't allow these in the url. I'm wondering if there's a good way of encrypting an integer and having only alphanumeric characters in the result? I'm trying to pass some data through the url. I know it's possible to do some workarounds (put data in database and pass the id to the row or something), but I really want to try it this way. Ideas?

  • Get window handle from window class name

    - by Einar Egilsson
    I'm trying to get a window handle on a child window in my process and the only information I have is the window class name. Are there any win32 functions I can use for that? I'm doing this from C#. A bit more detail: This is a Visual Studio plugin, written in C#. So my process is visual studio, which has lots of windows. One of them has a window class "VsTipWindow". I don't know the immediate parent window of that window, all I have is the class name. Is there any way for me to get the window handle from just that?

  • linker error in simple program: multiple definition of function

    - by BillyJean
    My function test is added to two different .cpp-files and the functions are private to their respective files as shown below test1.cpp #include <iostream> using namespace std; void test() { cout << "test" << endl; } test2.cpp #include <iostream> using namespace std; void test() { cout << "test" << endl; } main.cpp #include <iostream> using namespace std; int main() { return 0; } During linking I get the error multiple definition of test() - but how is that possible, considering that the two files have their own private scope!? I could understand it if I included the function prototype in each .cpp-files' corresponding header, but there is no such thing in this example.

    I'm using the systemfit() function to conduct a seemingly unrelated regression and am getting the following error: Error in solve(sigma, tol = solvetol) : Lapack routine dsptrf returned error code 1 Yet, I'm unable to find the meaningful interpretation of what the error suggests is going on. Below is some simulated code that works to show what functions I'm using (the simulated code does not produce an error). Thanks for thoughts on this error. y <- sample(seq(1:4), 100, replace = TRUE) x1 <- sample(seq(0:1), 100, replace = TRUE) -1 x2 <- sample(seq(0:1), 100, replace = TRUE) - 1 x3 <- sample(seq(1:4), 100, replace = TRUE) frame <- as.data.frame(cbind(y,x1,x2, x3)) mod_1 <- y ~ x1 + x3 + x1:x3 mod_2 <- y ~ x2 + x3 + x2:x3 output <- systemfit(list(mod_1, mod_2), data = frame, method = "SUR")

  • Group SQL tables in SQL Server Management Studio object explorer

    - by MainMa
    I have a table which has approximately sixty tables, and other tables are added constantly. Each table is a part of a schema. A such quantity of tables makes it difficult to use Microsoft SQL Server Management Studio 2008. For example, I must scroll up in object explorer to access database related functions, or scroll down each time I need to access Views or Security features. Is it possible to group several tables to be able to expand or collapse them in Object Explorer? Maybe a folder may be displayed for each schema, letting collapse the folders I don't need to use?

  • What to look for in estimating a PowerBuilder Conversion Project?

    - by tekiegreg
    Hi there, I've been trying to do a spec for a PowerBuilder 9 to 11.5 migration of a relatively complex application. Granted PowerBuilder is not really my specialty I'm having issues trying to justify an estimate for this part of the project (and the PowerBuilder people I've been talking with have had some personal issues lately and are out of communication). These are some of the metrics that we have seen and can evaluate: -PBL Files -Main Windows -Data Windows -Functions (no we don't have the source available on this project) What metrics in particular are helpful and how long would any given "unit" such as a Data Window take?

  • Has anybody use javafx on CDC J9?

    - by 4NDR01D3
    Is that possible?? I mean, I have an already working project that runs in windows mobile using the J9 virtual machine for CDC. My user interface there is using AWT and it works fine and it looks OK, but been honest it doesn't take real advantage of the devices were is running... So I start reading about JavaFX and that looks really cool, but all that I see about mobiles there is applied to CLDC, MIDP, etc. but my application is already running on CDC J9 and I can't change this cause I'm using a Derby database on it. So, my plan is to code the GUI again, but keeping the logic of the application. So do you guys think javafx is the way to go? or, am I wasting my time learning javafx for this project. Thanks in advance, Gustavo.

  • 'Design By Contract' in C#

    - by IAmCodeMonkey
    I wanted to try a little design by contract in my latest C# application and wanted to have syntax akin to: public string Foo() { set { Assert.IsNotNull(value); Assert.IsTrue(value.Contains("bar")); _foo = value; } } I know I can get static methods like this from a unit test framework, but I wanted to know if something like this was already built-in to the language or if there was already some kind of framework floating around. I can write my own Assert functions, just don't want to reinvent the wheel.

  • EC2 instance suddenly refusing SSH connections and won't respond to ping

    - by Chris
    My instance was running fine and this morning I was able to access a Ruby on Rails app hosted on it.

  • How do I close a database connection in a WCF service?

    - by Dan
    I have been unable to find any documentation on properly closing database connections in WCF service operations. I have a service that returns a streamed response through the following method. public virtual Message GetData() { string sqlString = BuildSqlString(); SqlConnection conn = Utils.GetConnection(); SqlCommand cmd = new SqlCommand(sqlString, conn); XmlReader xr = cmd.ExecuteXmlReader(); Message msg = Message.CreateMessage( OperationContext.Current.IncomingMessageVersion, GetResponseAction(), xr); return msg; } I cannot close the connection within the method or the streaming of the response message will be terminated. Since control returns to the WCF system after the completion of that method, I don't know how I can close that connection afterwards. Any suggestions or pointers to additional documentation would be appreciated. Dan

  • Lighttpd not cleanly restarting (address already in use)

    - by NilObject
    When doing a dist-upgrade recently, my lighttpd-1.4.19 install on Ubuntu 8.0.4 has begun failing to restart or reload properly with the /etc/init.d/lighttpd restart command. ~$ sudo /etc/init.d/lighttpd restart * Stopping web server lighttpd ...done. * Starting web server lighttpd 2009-06-13 04:06:36: (network.c.300) can't bind to port: 80 Address already in use ...fail!

The way I get around it is to kill lighttpd and then issue the start command, but it seems like I shouldn't have to do that :) I've looked at my config files, and can't spot any immediate errors.

  • designing an API wrapper for Twitter, Facebook, Youtube etc...

    - by John Stewart
    I am looking at some pointers on how to design a wrapper for these social networking sites. Ideally what I want to do is create a black box where I am able to create an interface for other libraries to call certain functions to interact with these social networking sites. I am planning on using oAuth for most of these sites, I already have this layer designed in PHP. The other layer that I need for these social sites is the ability to push and pull content. For example, the ability to pull feeds for users from each of these networks and then should I cache them on my end? how would I cache all twitter, facebook etc activity feed and be able to account for resync etc? The networks that I am looking at are: Twitter Youtube Facebook LinkedIN Vimeo Flickr I am looking for ideas on how to tackle this in php? Any suggestions, opensource systems that I can learn from?

  • How do I use Python's itertools.groupby()?

    - by James Sulak
    I haven't been able to find an understandable explanation of how to actually use Python's itertools.groupby() function. What I'm trying to do is this: take a list - in this case, the children of an objectified lxml element - divide it into groups based on some criteria, and then later iterate over each of these groups separately. I've reviewed the documentation (http://docs.python.org/lib/itertools-functions.html), and the examples, (http://docs.python.org/lib/itertools-example.html), but I've had trouble trying to apply them beyond a simple list of numbers. So, how do I use of itertools.groupby()? Is there another technique I should be using? Pointers to good "prerequisite" reading would also be appreciated.

  • jQuery AJAX not redirecting?

    - by MidnightLightning
    I have a simple PHP page (for testing) that simply calls header("Location: http://www.example.com");exit;, which resides on the same server, in the same directory as another file with the following jQuery Javascript: $(document).ready(function() { jQuery.ajax({ type : 'GET', url : 'bounce.php', error : function(xhr, status, error) { console.log("ERROR: ", xhr, xhr.status, xhr.getAllResponseHeaders()); }, complete : function(xhr, status) { // Get headers of the response console.log("COMPLETE: ", xhr, xhr.status, xhr.getAllResponseHeaders()); } }); }); I was expecting (from several other StackOverflow responses) for the xhr.status to return "302", but instead the AJAX call is triggering the "error" event (and then the "complete" event), and xhr.status is returning 0 (zero), and .getAllResponseHeaders() is coming back null (in both the error, and complete functions). Firebug is showing the "302 Moved Temporarily", and the response headers. So why is this triggering the error event, and not passing along the proper 302 code, and headers? Is this something to do with the Same Origin since the bouncing script and the fetching script are both on the same server? Is this jQuery or Javascript's fault?
