  • RPC for java/python with rest support, HTML monitoring and goodies

    - by Ran
    Here's my set of requirements: I'm looking for an RPC framework such as thrift, avro, protobuf (when adding services to it) which supports: Easy and intuitive IDL. No serial numbers, no manual versioning, simple... avro is a good example for this. Works with Java and Python Supports both fast binary prorocol, as well as HTTP based restful style. I'd like to be able to use it for both backend-to-backend communication (java-java or python-java) as well as frontend-to-backend communication (javascript to java). The rest support needs to include &param=value input as get/post requests (configurable per request) and output in three possible formats: json, jsonp, XML. Compact, fast, backward compatible, easy to upgrade etc... Provides some nice monitoring interfaces such as: JMX, web page status reports (e.g. packets in, packets out, error rate etc) Ops friendly... no need to take the whole site down to release new versions Both sync and asyc communication ... other goodies are welcome... Is there something out there? So far I've looked at thrift and avro and they are both nice in some ways, but don't check all my list. Thanks

  • Piping EOF problems with stdio and C++/Python

    - by yeus
    I got some problems with EOF and stdio. I have no idea what I am doing wrong. When I see an EOF in my program I clear the stdin and next round I try to read in a new line. The problem is: for some reason the getline function immediatly (from the second run always, the first works just as intended) returns an EOF instead of waiting for a new input from py python process... Any idea? alright Here is the code: #include <string> #include <iostream> #include <iomanip> #include <limits> using namespace std; int main(int argc, char **argv) { for (;;) { string buf; if (getline(cin,buf)) { if (buf=="q") break; /*****///do some stuff with input //my actual filter program cout<<buf; /*****/ } else { if ((cin.rdstate() & istream::eofbit)!=0)cout<<"eofbit"<<endl; if ((cin.rdstate() & istream::failbit)!=0)cout<<"failbit"<<endl; if ((cin.rdstate() & istream::badbit)!=0)cout<<"badbit"<<endl; if ((cin.rdstate() & istream::goodbit)!=0)cout<<"goodbit"<<endl; cin.clear(); cin.ignore(numeric_limits<streamsize>::max()); //break;//I am not using break, because I //want more input when the parent //process puts data into stdin; } } return 0; } and in python: from subprocess import Popen, PIPE import os from time import sleep proc=Popen(os.getcwd()+"/Pipingtest",stdout=PIPE,stdin=PIPE,stderr=PIPE); while(1): sleep(0.5) print proc.communicate("1 1 1") print "running"

  • Memory not being returned after function python call

    - by Dan
    I've got a function which does a parse of a sentence by building up a big chart. For some reason, Python holds on to whatever memory was allocated during that function call. That is, I do best = translate(sentence, grammar) and somehow my memory goes up and stays up. Here is the function: from string import join from heapq import nsmallest, heappush def translate(f, g): words = f.split() chart = {} for col in range(len(words)): for row in reversed(range(0,col+1)): # get rules for this subspan rules = g[join(words[row:col+1], ' ')] # ensure there's at least one rule on the diagonal if not rules and row==col: rules=[(0.0, join(words[row:col+1]))] # pick up rules below & to the left for k in range(row,col): if (row,k) and (k+1,col) in chart: for (w1, e1) in chart[row, k]: for (w2, e2) in chart[k+1,col]: heappush(rules, (w1+w2, e1+' '+e2)) # add all rules to chart chart[row,col] = nsmallest(MAX_TRANSLATIONS, rules) (w, best) = chart[0, len(words)-1][0] return best EDIT: Using Python 2.7 on OS X. The grammar g is just a dictionary from strings to heaps, e.g.: g['et'] [(1.05, 'and'), (6.92, ', and'), (9.95, 'and ,'), (11.17, 'and to')] EDIT: If you want to run the code, try the sentence "Cela est difficile" with the following grammar: >>> g['cela'] [(8.28, 'this'), (11.21, 'it'), (11.57, 'that'), (15.26, 'this ,')] >>> g['est'] [(2.69, 'is'), (10.21, 'is ,'), (11.15, 'has'), (11.28, ', is')] >>> g['difficile'] [(2.01, 'difficult'), (10.08, 'hard'), (10.19, 'difficult ,'), (10.57, 'a difficult')]

  • Generating python wrapper for 3ed party c++ dll using swig with

    - by MuraliK
    I am new bee to swig. I have a third party c++ dll with the following functions export. I want to call these dll functions in python. So thought of using swig to generate the wrapper using swig. I am not sure what sort of wrapper i need to generate (do i need to generate .lib or .dll to use it in python?). In case i need to generate .dll how do i do that using visual studio 2010. There are some call back function like SetNotifyHandler(void (__stdcall * nf)(int wp, void *lp)) in the bellow list. How do define such function in interface file. can someone help me plese? enter code here #ifndef DLL_H #define DLL_H #ifdef DLL_BUILD #define DLLFUNC __declspec(dllexport) #else #define DLLFUNC __declspec(dllimport) #endif #pragma pack(push) #pragma pack(1) #pragma pack(pop) extern "C" { DLLFUNC int __stdcall StartServer(void); DLLFUNC int __stdcall GetConnectionInfo(int connIndex, Info *buf); DLLFUNC void __stdcall SetNotifyWindow(HWND nw); DLLFUNC void __stdcall SetNotifyHandler(void (__stdcall * nf)(int wp, void *lp)); DLLFUNC int __stdcall SendCommand(int connIndex, Command *cmd); };

  • How to remove iso 9660 from USB?

    - by a_m0d
    I have somehow managed to write an iso 9660 image onto my USB drive, which makes all my computer think that the device is actually a CD. I have tried various methods of removing this partition, but nothing seems to work. I have tried fdisk, which says $ fdisk -l /dev/sdb Cannot open /dev/sdb parted crashes when I try to use it on this device. I have even tried $ dd if=/dev/zero of=/dev/sdb but it just hangs with no output (either on screen or on disk). However, when I plug the USB in, it does mount, and I can view (but not edit) the files on it. edit: now the result is $ dd if=/dev/zero of=/dev/sdb dd: opening `/dev/sdb': Read-only file system I have also tried re-formatting it on Windows, but it gets to the end of the format process and then says "Couldn't format the drive". How can I remove this partition and get my whole USB drive back to normal again? EDIT 1: Trying a simple mkfs doesn't work: $ sudo mkfs -t vfat /dev/sdb mkfs.vfat 3.0.0 (28 Sep 2008) mkfs.vfat: Will not try to make filesystem on full-disk device '/dev/sdb' (use -I if wanted) I can't do mkfs on /dev/sdb1 because there is no such partition, as shown:$ ls /dev | grep sdb sdb EDIT 2: This is the information posted by dmesg when I plug the device in:$ dmesg . .

  • Error When Loading Images on Local Host Test Server

    - by ke4ktz
    I have a peculiar problem that I just can't seem to find an explanation. I'm working on an AngularJS site for our family and am integrating data from various web services. Currently I am working on the photos section which will integrate in photos from our Flickr account. I have a main page which lists the various photo sets and displays the set's primary photo along with the title. (Note: I'm using the Flickr 'extras' parameter to return the primary photo's URL in the API calls.) <div data-ng-repeat="p in vm.photoSets"> <a ng-href="#/photos/{{p.id}}"> <img ng-src="{{p.primary_photo_extras.url_s}}"></img> </a> <h4>{{p.title._content}}</h4> </div> When clicking on the photo, the routing will display a page with a list of all the photos from that set, showing the image and the title. <div data-ng-repeat="p in vm.photoSetData.photo"> <a ng-href="#/photos/{{vm.photoSetId}}/{{p.id}}" <img ng-src="{{p.url_s}}"></img> </a> <h4>{{p.title}}</h4> </div> Now, here's where the problem is occuring. When I upload the code to my public website on my hosting provider, everything works just fine. Both pages display their respective photos. However, when I attempt to run the site on my local system, either in MAMP or NodeJS (using http-server), the second page gives me an error for each image: Error: [$interpolate:interr] Can't interpolate: {{p.url_s}} Error: [$sce:insecurl] Blocked loading resource from url not allowed by $sceDelegate policy.

In fact, the image title does display! I've tested it with Firefox, Safari and Chrome...all three browsers fail. I cannot find any explanation as to why it would work remotely but fail locally. Also, the images show up on the first page, but not on the second, even though one of the images on the second page is the same image URL as on the first page. Even going directly to the second page, bypassing the first page, still fails. Any ideas on how to fix this? It would be nice to test locally without having to upload to the server each time I make a change. Update: I have shut off the $sce security to see if that was causing the issue. Although it resulted in turning the error off, the files still don't load on the local test server. I have used the developer tools' network monitor and it doesn't even show an attempt to retrieve the files. AngularJS appears to shut down the retrieval, although the correct path shows up in the DOM.

  • Suds array of arrays not nesting

    - by joshcartme
    Let me preface this by saying that I am still pretty new to SOAP and how things should work. I'm working with the Vertical Response API. I'm having trouble getting suds to construct the xml correctly for a request. Here is some code: from suds.client import Client url = 'https://api.verticalresponse.com/wsdl/1.0/VRAPI.wsdl' client = Client(url) vr = client.service ... test_list = ( ( { 'name' : 'email_address', 'value' : login['username'], }, { 'name' : 'First_Name', 'value' : 'VR_User', } ), ( { 'name' : 'email_address', 'value' : '[email protected]', }, { 'name' : 'First_Name', 'value' : login['username'], }, ), ) # sid and cid are correctly retrieved prior to this point print "Sending test message..." vr.sendEmailCampaignTest({ 'session_id' : sid, 'campaign_id' : cid, 'recipients' : test_list, }) In this context login['username'] is just an email address. That code raises this error: suds.WebFault: Server raised fault: 'Application failed during request deserialization: Too many elements in array. 4 instead of claimed 2 (2) Here is the the definition of sendEmailCampaignTest: http://developers.verticalresponse.com/api/soap/methods/campaigns/sendemailcampaigntest/ Here is the xml that logging outputs (I removed the session_id and list_id for display here): DEBUG:suds.client:headers = {'SOAPAction': u'"VR/API/1_0#sendEmailCampaignTest"', 'Content-Type': 'text/xml; charset=utf-8'} ERROR:suds.client:<?xml version="1.0" encoding="UTF-8"?> <SOAP-ENV:Envelope xmlns:ns3="http://api.verticalresponse.com/1.0/VRAPI.xsd" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:ns0="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://www.w3.org/2001/XMLSchema" xmlns:ns2="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ns4="VR/API/1_0" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"> <SOAP-ENV:Header/> <ns0:Body> <ns4:sendEmailCampaignTest> <args xsi:type="ns3:sendEmailCampaignTestArgs"> <session_id xsi:type="ns1:string">redacted</session_id> <campaign_id xsi:type="ns1:int">redacted</campaign_id> <recipients xsi:type="ns3:ArrayOfNVDictionary" ns2:arrayType="ns3:NVDictionary[2]"> <item> <name xsi:type="ns1:string">email_address</name> <value xsi:type="ns1:string">[email protected]</value> </item> <item> <name xsi:type="ns1:string">First_Name</name> <value xsi:type="ns1:string">VR_User</value> </item> <item> <name xsi:type="ns1:string">email_address</name> <value xsi:type="ns1:string">[email protected]</value> </item> <item> <name xsi:type="ns1:string">First_Name</name> <value xsi:type="ns1:string">[email protected]</value> </item> </recipients> </args> </ns4:sendEmailCampaignTest> </ns0:Body> </SOAP-ENV:Envelope> DEBUG:suds.client:http failed: <?xml version="1.0" encoding="UTF-8"?><SOAP-ENV:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"><SOAP-ENV:Body><SOAP-ENV:Fault><faultcode>SOAP-ENV:Client</faultcode><faultstring>Application failed during request deserialization: Too many elements in array. 4 instead of claimed 2 (2) </faultstring></SOAP-ENV:Fault></SOAP-ENV:Body></SOAP-ENV:Envelope> a ruby script (provided by Vertical Response) that does the same things as the script I am working on in python outputs the following xml (I removed the session_id and list_id): <?xml version="1.0" encoding="utf-8" ?> <env:Envelope xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <env:Body> <n1:sendEmailCampaignTest xmlns:n1="VR/API/1_0" env:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"> <args xmlns:n2="http://api.verticalresponse.com/1.0/VRAPI.xsd" xsi:type="n2:sendEmailCampaignTestArgs"> <session_id xsi:type="xsd:string">redacted</session_id> <campaign_id xsi:type="xsd:int">redacted</campaign_id> <recipients xmlns:n3="http://schemas.xmlsoap.org/soap/encoding/" xsi:type="n3:Array" n3:arrayType="n2:NVDictionary[2]"> <item xsi:type="n3:Array" n3:arrayType="n2:NVPair[2]"> <item> <name xsi:type="xsd:string">email_address</name> <value href="#id9496430"></value> </item> <item> <name xsi:type="xsd:string">First_Name</name> <value xsi:type="xsd:string">VR_User</value> </item> </item> <item xsi:type="n3:Array" n3:arrayType="n2:NVPair[2]"> <item> <name xsi:type="xsd:string">email_address</name> <value xsi:type="xsd:string">[email protected]</value> </item> <item> <name xsi:type="xsd:string">First_Name</name> <value href="#id9496430"></value> </item> </item> </recipients> </args> </n1:sendEmailCampaignTest> <value id="id9496430" xsi:type="xsd:string" env:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">[email protected]</value> </env:Body> </env:Envelope> I understand that the error is in the construction of recipients.

So my question is how can I get suds to correctly construct the xml?

  • Java Port Socket Programming Error

    - by atrus-darkstone
    Hi- I have been working on a java client-server program using port sockets. The goal of this program is for the client to take a screenshot of the machine it is running on, break the RGB info of this image down into integers and arrays, then send this info over to the server, where it is reconstructed into a new image file. However, when I run the program I am experiencing the following two bugs: The first number recieved by the server, no matter what its value is according to the client, is always 49. The client only sends(or the server only receives?) the first value, then the program hangs forever. Any ideas as to why this is happening, and what I can do to fix it? The code for both client and server is below. Thanks!

  • Grabbing all <a> tags in a specific div and displaying them

    - by Taylor Swyter
    So I'v got a small problem with my portfolio site (you can see it at here) When you click on a portfolio piece, a top section opens up to reveal the details (Title, year, role, description) as well as the photos. I'v been able to get each project to replace all the text data, but I can't seem to get the images to load into the thumbnails. I have been able to get the last image i'm looking for in all of the images on the site, but not display each photo for each project. Here's the HTML i'm working with: <section id="details"> <div class="pagewrapper"> <section id="main-img"> <article id="big-img"> <img src="" alt="big-img" /> </article> <article class="small-img-container"> <a href="#"><img src="#" alt="smallimg" class="small-img" /></a> </article> </section> <section id="description"> <h3></h3> <h4></h4> <h5></h5> <p></p> </section> </div> <div class="clear"></div> </section> <section id="portfolio"> <div class="pagewrapper"> <h2 class="sectionTitle">Portfolio</h2> <div class="thumb"> <a class="small" href="#" title="David Lockwood Music" data-year="2010" data-role="Sole Wordpress Developer" data-description="David Lockwood is a musician and an educator based in New Hampshire who came to me needing a website for his musical career.

  • Is it possible to add files to the "Wordpress Media Library" using the command line?

    - by Tom
    Wordpress has it's own "Media Library" which is used when you upload images and other media for use in blog posts and pages. The advantage of the media library is that it automatically produces thumbnails of the images and the web interface gives you extra info such as who uploaded the image, which articles use the image, etc. My question is, does anyone have any tips on interacting with the media library via the command line instead of using the Wordpress web interface? For example, any ideas on how to add a image to the media library from the command line? If I copy files to the media library directory (usually .../wp-content/uploads/YYYY/MM/) from the command line they do not show up in the Wordpress dashboard - I guess because there needs to be an associated database entry for the media to be registered with Wordpress.

  • VMWare Lab Manager: What's the best way to build Library Configurations?

    - by mcohen75
    We're using Lab Manager within our QA group. We use it to quickly deliver environments we need for testing. We have 25 Templates, 14 Library Configurations and counting. To build up our templates we: Create a base template that is a bare bones version of Server 2008 + basic configuration (Windows Update, Firewall exceptions) Create a linked clone for each Server template we need (SQL Server 08, 05, etc) Repeat for other OS's, like Windows 7 and Windows XP Then we create configurations: Create a workspace configuration with multiple images in it (Say Server 08 w/SQL Server and Windows 7) Deploy the configuration and make some minor configuration changes Undeploy and Capture to Library How do we keep this manageable? When I need to update a configuration, should I: Rebuild it from templates Clone it to a workspace, make changes, recapture it to the library keep the configuration in my workspace (don't delete it after capturing it to library), deploy it to make changes and then re-capture to library

  • Why is HttpClient's GetStringAsync is unbelivable slow?

    - by Jason94
    I have a Windows Phone 8 project where I've taken to use the PCL (Portable Class Library) project too since I'm going to build a Win8 app to. However, while calling my api (in Azure) my HttpClient's GetStringAsync is so slow. I threw in a couple of debugs with datetime and GetStringAsync took like 14 seconds! And sometimes it takes longer. What I'm doing is retrieving simple JSON from my Azure API site. My Android client has no problem with getting that same data in a split second... so is there something I'm missing? The setup is pretty straight forward: HttpClient client = new HttpClient(); client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json")); client.DefaultRequestHeaders.Add("X-Token", "something"); string responseJSON = await client.GetStringAsync("url"); I've places the debug times right before and after the await there, in between it is 14 seconds! Does someone know why?

  • Cast error on SQLDataReader (entlib 5.0, asp.net 3.5, vb)

    - by Phil
    My site is using enterprise library v 5.0. Mainly the DAAB. Some functions such as executescalar, executedataset are working as expected. The problems appear when I start to use Readers I have this function in my includes class: Public Function AssignedDepartmentDetail(ByVal Did As Integer) As SqlDataReader Dim reader As SqlDataReader Dim Command As SqlCommand = db.GetSqlStringCommand("select seomthing from somewhere where something = @did") db.AddInParameter(Command, "@did", Data.DbType.Int32, Did) reader = db.ExecuteReader(Command) reader.Read() Return reader End Function This is called from my aspx.vb like so: reader = includes.AssignedDepartmentDetail(Did) If reader.HasRows Then TheModule = reader("templatefilename") PageID = reader("id") Else TheModule = "#" End If This gives the following error on db.ExecuteReader line: Unable to cast object of type 'Microsoft.Practices.EnterpriseLibrary.Data.RefCountingDataReader' to type 'System.Data.SqlClient.SqlDataReader'. Can anyone shed any light on how I go about getting this working. Will I always run into problems when dealing with readers via entlib?

  • WCF ValidationFault

    - by RandomNoob
    I'm using Validation Application Block - Enterprise Library to validate parameters sent to my WCF Service operations. For instance, a certain operation requires the parameter to either be a 1 or 6, like so: [OperationContract(Name="GetEmployeesByRegion")] [FaultContract(typeof(ValidationFault))] List<Employees> GetEmployeesByRegion([DomainValidator(1,6)]int regionId); This works just fine i.e the validation fault occurs however, when the service is invoked by the client, a generic System.ServiceModel.FaultException is thrown. An the message indicates: "The creator of this fault did not specify a reason." Now, I could check the parameters myself before the service cal and throw a custom fault but that seems to defeat the purpose of attribute based validation of parameters using the Validation Application Block. Is there anyway to customize the error returned by the validation Fault? It is also possible I'm doing something completely wrong. I just want the caller to know that he/she should have passed in a 1 or 6 in the exception message. Is this possible?

  • ExceptionPolicy.HandleException does not install Event Source for Logging in Registry if XBAP run ou

    - by Neo
    I am using the Logging Application Block (of Microsoft Enterprise Library) to log exceptions in the Event Viewer that occur in my WPF XBAP application. If I run the XBAP in the debugger from Visual Studio, an Event Source entry for my application is automatically created in the Registry at: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\Application\MyApp This occurs at the point ExceptionPolicy.HandleException() is called. However, if I run the XBAP outside of the IDE directly from the file system or from its published location, the Registry entry isn't added. Therefore, no logging takes place. I can only assume this is a security issue with running XBAP applications and they do not have access to write to the Registry. Is this a setting within my project? Any idea on why this might be happening? Any help much appreciated.

  • Sparse matrices / arrays in Java

    - by DanM
    I'm working on a project, written in Java, which requires that I build a very large 2-D sparse array. Very sparse, if that makes a difference. Anyway: the most crucial aspect for this application is efficency in terms of time (assume loads of memory, though not nearly so unlimited as to allow me to use a standard 2-D array -- the key range is in the billions in both dimensions). Out of the kajillion cells in the array, there will be several hundred thousand cells which contain an object. I need to be able to modify cell contents VERY quickly. Anyway: Does anyone know a particularly good library for this purpose? It would have to be Berkeley, LGPL or similar license (no GPL, as the product can't be entirely open-sourced). Or if there's just a very simple way to make a homebrew sparse array object, that'd be fine too. I'm considering MTJ, but haven't heard any opinions on its quality. Thanks!! -Dan

  • Boolean Expression Evaluation in Java

    - by Trilok
    Hey everyone, Is there a relatively simpler (when compared with writing a parser) way to evaluate boolean expressions in Java? I do not want to use the JEP library. I have a String expression something like: (x 4 || x < 8 && p 6) [ I will replace the variables with values. Is there a way by which I can evaluate this expression? The problem is, this can be any level deep. So, writing a parser would be really complex. Thanks

  • Common and useful Graph functions?

    - by Nazgulled
    Hi, I'm implementing a simple Graph library for my uni project and since this is the first time I'm dealing with graphs, I would like to know which functions you guys consider to be most common and useful for Graph implementations... So far, I have this: graphInitialize() graphInsertVertex() graphRemoveVertex() graphGetVertex() graphGetVertexValue() (not implemented yet, not sure if I'll need it) graphInsertEdge() graphRemoveEdge() graphLinkVertices() (this calls graphInsertEdge twice for bidirectional graph) graphUnlinkVertices() (this calls graphRemoveEdge twice for bidirectional graph) graphDestroy() I know I'm missing a function do determine the shortest path, but I'm leaving that for last... Do you think I'm missing any common/useful function?

But, when it is on the Form B, the OutOfMemoryException is raised. Why ?

  • Avoiding thumbnail name collisions with sorl-thumbnail

    - by Owen Nelson
    Understanding that I should probably just dig into the source to come up with a solution, I'm wondering if anyone has come up with a tactic for dealing with this. In my project, I have a lot of images being generated outside of the application. I'm isolating them on the filesystem based on a model's pk. For example, a model instance with a pk of 121 might have the following images: .../thumbs/1/2/1/img.1.jpg .../thumbs/1/2/1/img.2.jpg ... .../thumbs/1/2/1/img.27.jpg Since the image filenames themselves are not guaranteed to be unique, I'm looking for a way to inform sorl (at runtime) that I'd like to prefix thumbs for this model with the instance pk value. Is this even possible without patching sorl?
