  • How did craigspro license Craigslist content? [closed]

    - by Joshua Frank
    There's an app called craigspro that provides a much better interface to Craigslist on mobile devices. They claim that the app is Officially Licensed by Craigslist, but I thought Craigslist never licensed their content, and the only thing I can find on the subject in the terms of use is this: Any copying, aggregation, display, distribution, performance or derivative use of craigslist or any content posted on craigslist whether done directly or through intermediaries (including but not limited to by means of spiders, robots, crawlers, scrapers, framing, iframes or RSS feeds) is prohibited. As a limited exception, general purpose Internet search engines and noncommercial public archives will be entitled to access craigslist without individual written agreements executed with CL that specifically authorize an exception to this prohibition if ... Does anyone know how do get a "written agreement" with Craigslist, and roughly what their terms would be? Do they charge a fee, or just check that you're not evil? I'll try next with Craigslist directly, but I'd like to get a sense of the landscape before stumbling in.

  • Data Governance (Veri Yönetisimi)

    - by Arda Eralp
    Data governance,veri ile ilgili islemler için bir sorumluluklar sistemidir. Bu sistemin temelini ise politikalar, standartlar ve prosedürler olusturur. Sistem politikalar, standartlar ve prosedürler sayesinde verinin ne zaman, hangi sartlar altinda, hangi eylemlerde, hangi yöntemler ile kimler tarafindan kullanilacagina karar verir. Sistemin kurumda basarili bir sekilde islemesi için öncelikle kurumda farkindalik saglanmasi gereklidir. Farkindalik saglandiktan sonra ise kurum governance ve mimari kültürünü benimsemelidir. Ancak bu sartlar altinda sistem basarili bir sekilde isleyebilecektir. Bu sebeplerden dolayidir ki data governance kisa bir süreç degil, aksine kurum varligini sürdürdügü sürece isleyecek olan bir süreçtir. Bu durum bize data governance in bir proje degil bir program oldugunu açiklamaktadir. Programin baslangicinda kurumun ihtiyaçlarinin netlesmesi ve farkindaligin saglanmasi temeldir. Hedef kitle ise, veri ile dogrudan ve ya dolayli olarak iliski içerisinde olan herkesdir. Bu sebeple programin baslangicinda hedef kitleyi içeren ekipler ile toplantilar düzenlenecektir. Bu toplantilar sayesinde hem farkindalik saglanacak hemde ekiplerin ihtiyaçlari birebir ekipler tarafindan aktarilarak netlesecektir. Hedef kitlenin ihtiyaçlari netlestirildikten sonra ise devamli isleyecek olan bu sürecin planlamasi yapilacaktir. Bu sürecin planlanmasinda ihtiyaçlarin önceliklendirilmesi gerekmektedir. Sebebi ise her ekibin ihtiyaçlarinin farkli olabilecegi ve bütün ihtiyaçlara ayni anda karsilik verilemeyebileceginin öngörülmesidir. Bu öngörünün temeli ise ekiplerin ihtiyaçlarinin birbirleriyle olan baglantisidir. Süreç planlamasinda ihtiyaçlarin önceliklendirilmesinin ardindan kurumun büyüklügünün gözönünde bulundurulmasi gerekmedir. Kurumun büyüklügünün önemi ise eger kurum bir bütün olarak ayni anda govern edilemeyecek kadar büyük ise ihtiyaçlari öncelikli olarak bulunan ekipler ile govern edilmesine baslanarak sürecin belirli bir hiz ile bütün kurumda isler hale getirilmesini saglamaktir. Ihtiyaçlar belirlendikten ve ilgili ekipler seçildikten sonra artik programin planlanmasina geçilebilecek. Programin planlama asamasinda öncelikli olarak sürecin asamalarini kontrol edecek ve süreç kurum içerisinde isleyise geçtiginde kontrolü saglayacak olan Data Governance Office in planlanmasidir. Office in planlanmasiyla birlikte süreçteki roller ve bu rollerin sorumluluklari belirlenecektir. Planlama asamasinda Data governance office, roller ve sorumluluklar, güvenlik ve veri saklanan sistemler ele alinacak konulardir. Planlama asamasi tamamlandiginda ise belirlenen ekipler ve ihtiyaçlar dogrultusunda programin isleyis asamasina geçilebilecektir. Isleyis kisminda ekibin ihtiyaçlari dogrultusunda güvenlik konusunda ve veri saklanan sistemler üzerinde çalismalar yapilacaktir. Bu yapilan çalismalar bir süreç olarak dökümante edilecek ve süreç sona erdiginde baska bir ekiple baska bir ihtiyaç dogrultusunda çalisma yapilarak ayni süreç isletilecek ve böylece kurum içesinde ilgili süreçte standartlasma saglanacaktir. Güvenlik konusunda verinin erisim güvenligi ve kullanim güvenligi ele alinacaktir. Veri saklanan sistemler üzerindeki çalismalar ise saklanan sistemlerin program dahilinde belirlenen standartlar ile olusturulmasi ve yönetilmesi saglanacaktir. Isleyis kisminin ardindan ise programin izleme kismina geçilecektir. Bu kisimda artik Data Governance Office olusmus, politikalar, standartlar ve prosedürler belirlenmistir. Ve Data Governance Office çalisanlari rolleri ve sorumluluklari dahilinde programin isleyisini izleyecek ve gerek gördügünde politikalar standartlar ve prosedürler üzerinde degisiklikler yapacaklardir.

  • SQL 2014 does data the way developers want

    - by Rob Farley
    A post I’ve been meaning to write for a while, good that it fits with this month’s T-SQL Tuesday, hosted by Joey D’Antoni (@jdanton) Ever since I got into databases, I’ve been a fan. I studied Pure Maths at university (as well as Computer Science), and am very comfortable with Set Theory, which undergirds relational database concepts. But I’ve also spent a long time as a developer, and appreciate that that databases don’t exactly fit within the stuff I learned in my first year of uni, particularly the “Algorithms and Data Structures” subject, in which we studied concepts like linked lists. Writing in languages like C, we used pointers to quickly move around data, without a database in sight. Of course, if we had a power failure all this data was lost, as it was only persisted in RAM. Perhaps it’s why I’m a fan of database internals, of indexes, latches, execution plans, and so on – the developer in me wants to be reassured that we’re getting to the data as efficiently as possible. Back when SQL Server 2005 was approaching, one of the big stories was around CLR. Many were saying that T-SQL stored procedures would be a thing of the past because we now had CLR, and that obviously going to be much faster than using the abstracted T-SQL. Around the same time, we were seeing technologies like Linq-to-SQL produce poor T-SQL equivalents, and developers had had a gutful. They wanted to move away from T-SQL, having lost trust in it. I was never one of those developers, because I’d looked under the covers and knew that despite being abstracted, T-SQL was still a good way of getting to data. It worked for me, appealing to both my Set Theory side and my Developer side. CLR hasn’t exactly become the default option for stored procedures, although there are plenty of situations where it can be useful for getting faster performance. SQL Server 2014 is different though, through Hekaton – its In-Memory OLTP environment. When you create a table using Hekaton (that is, a memory-optimized one), the table you create is the kind of thing you’d’ve made as a developer. It creates code in C leveraging structs and pointers and arrays, which it compiles into fast code. When you insert data into it, it creates a new instance of a struct in memory, and adds it to an array. When the insert is committed, a small write is made to the transaction to make sure it’s durable, but none of the locking and latching behaviour that typifies transactional systems is needed. Indexes are done using hashes and using bw-trees (which avoid locking through the use of pointers) and by handling each updates as a delete-and-insert. This is data the way that developers do it when they’re coding for performance – the way I was taught at university before I learned about databases. Being done in C, it compiles to very quick code, and although these tables don’t support every feature that regular SQL tables do, this is still an excellent direction that has been taken. @rob_farley

  • Init.d script gets return code 1 when calling itself, how can I get output?

    - by Per
    My question is, how can I modify the script so that it will tell me what goes wrong? The scenario is this: I'm trying to get Sonatype Nexus to start as a service in Ubuntu 10.04, and it just will not work. (I'm not looking for help on how to run Nexus, but on how to get some useful output from a script) It works when invoking it with sudo /etc/init.d/nexus start but fails when using sudo service nexus start I have run the update-rc.d command on it, and done everything according to instructions. The nexus init.d-script has a point where it calls itself when it detects that it should run as another user ('nexus'): su -m $RUN_AS_USER -c "\"$REALPATH\" $2" which expands to su -m nexus -c '"/opt/nexus-2.0.2/bin/jsw/linux-x86-64/nexus" start' when adding the -x debug flag to the script. This command results in return code 1. It never executes - I've set -x debug flag on the script, placed echo commands with redirect to file at the start of script to trace, etc. I cannot get any output telling me why the command will not execute. I've tried appending redirect to file after the above script line, inside the quotes, outside, any way I could imagine. All info I can get is by inserting a line echo $? after the su line, which outputs '1'. Is there a way I can see what happens when the su command runs?

  • Strategy for avoiding duplicate object ids for data shared across devices using iCloud

    - by rmaddy
    I have a data intensive iOS app that is not using CoreData nor does it support iCloud synching (yet). All of my objects are created with unique keys. I use a simple long long initialized with the current time. Then as I need a new key I increment the value by 1. This has all worked well for a few years with the app running isolated on a single device. Now I want to add support for automatic data sync across devices using iCloud. As my app is written, there is the possibility that two objects created on two different devices could end up with the same key. I need to avoid this possibility. I'm looking for ideas for solving this issue. I have a few requirements that the solution must meet: 1) The key needs to remain a single integral data type. Converting all existing keys to a compound key or to a string or other type would affect the entire code base and likely result in more bugs than it's worth. 2) The solution can't depend on an Internet connection. A user must be able to run the app and add data even with no Internet connection. The data should still resolve properly later when the data syncs through iCloud once a connection is available. I'll accept one exception to this rule. If no other option is available, I may be open to requiring an Internet connection the first time the app's data is initialized. One idea I have been toying around with in my head is logically splitting the integer key into two parts. The high 4 or 5 bits could be used as some sort of device id while the rest represents the actual key. The fuzzy part is figuring out how to come up with non-conflicting device ids that fit in a few bits. This should be viable since I don't need to deal will millions of devices. I just need to deal with the few devices that would be shared by a given iCloud account. I'm open to suggestions. Thanks.

  • Tutorial how to create a CXF web service from existing Java code and embed it in Tomcat

    - by EugeneP
    Do you know a tutorial how to create a CXF web service from existing Java code and embed it in Tomcat, and also generate a wsdl file so that any .NET system would be able to generate client code easily? I miss that WSDL creation point in, for example this http://www.ibm.com/developerworks/library/ws-pojo-springcxf/ tutorial. No wsdl file is generated. But still it should be present in my case to provide system interoperability.

  • JGoodies HashMap

    - by JohnMcClane
    Hi, I'm trying to build a chart program using presentation model. Using JGoodies for data binding was relatively easy for simple types like strings or numbers. But I can't figure out how to use it on a hashmap. I'll try to explain how the chart works and what my problem is: A chart consists of DataSeries, a DataSeries consists of DataPoints. I want to have a data model and to be able to use different views on the same model (e.g. bar chart, pie chart,...). Each of them consists of three classes. For example: DataPointModel: holds the data model (value, label, category) DataPointViewModel: extends JGoodies PresentationModel. wraps around DataPointModel and holds view properties like font and color. DataPoint: abstract class, extends JComponent. Different Views must subclass and implement their own ui. Binding and creating the data model was easy, but i don't know how to bind my data series model. package at.onscreen.chart; import java.beans.PropertyChangeListener; import java.beans.PropertyChangeSupport;

  • Spring boot JAR as windows service

    - by roblovelock
    I am trying to wrap a spring boot "uber JAR" with procrun. Running the following works as expected: java -jar my.jar I need my spring boot jar to automatically start on windows boot. The nicest solution for this would be to run the jar as a service (same as a standalone tomcat). When I try to run this I am getting "Commons Daemon procrun failed with exit value: 3" Looking at the spring-boot source it looks as if it uses a custom classloader: https://github.com/spring-projects/spring-boot/blob/master/spring-boot-tools/spring-boot-loader/src/main/java/org/springframework/boot/loader/JarLauncher.java I also get a "ClassNotFoundException" when trying to run my main method directly. java -cp my.jar my.MainClass Is there a method I can use to run my main method in a spring boot jar (not via JarLauncher)? Has anyone successfully integrated spring-boot with procrun? I am aware of http://wrapper.tanukisoftware.com/. However due to their licence I can't use it. UPDATE I have now managed to start the service using procrun. set SERVICE_NAME=MyService set BASE_DIR=C:\MyService\Path set PR_INSTALL=%BASE_DIR%prunsrv.exe REM Service log configuration set PR_LOGPREFIX=%SERVICE_NAME% set PR_LOGPATH=%BASE_DIR% set PR_STDOUTPUT=%BASE_DIR%stdout.txt set PR_STDERROR=%BASE_DIR%stderr.txt set PR_LOGLEVEL=Error REM Path to java installation set PR_JVM=auto set PR_CLASSPATH=%BASE_DIR%%SERVICE_NAME%.jar REM Startup configuration set PR_STARTUP=auto set PR_STARTIMAGE=c:\Program Files\Java\jre7\bin\java.exe set PR_STARTMODE=exe set PR_STARTPARAMS=-jar#%PR_CLASSPATH% REM Shutdown configuration set PR_STOPMODE=java set PR_STOPCLASS=TODO set PR_STOPMETHOD=stop REM JVM configuration set PR_JVMMS=64 set PR_JVMMX=256 REM Install service %PR_INSTALL% //IS//%SERVICE_NAME% I now just need to workout how to stop the service. I am thinking of doing someting with the spring-boot actuator shutdown JMX Bean. What happens when I stop the service at the moment is; windows fails to stop the service (but marks it as stopped), the service is still running (I can browse to localhost), There is no mention of the process in task manager (Not very good! unless I am being blind).

  • Tracking downloads of your software + software CDN?

    - by jason l baptiste
    I'm primarily a web app developer/entrepreneur, so there's a lot I don't know about the desktop software distribution process. I've been thinking about making a Mac OS X app for fun, that I would distribute for free or a really small donation, but started thinking about distribution+download analytics: a) How do you host your software? Just on your web server/amazon s3 as the CDN? b) How do you track download analytics? On the flip side, I've thought about developing a simple service that does just this: Offers CDN hosting for software downloads, analytics by version, lets users share the app upon download, and makes the whole process a lot easier for ISVs. Curious to get feedback. Thanks! -jlb

  • Installing Python Script, Maintaining Reference to Python 2.6

    - by zfranciscus
    Hi, I am writing a Python program that relies on version 2.6. I went through the distribution documentation: http://docs.python.org/distutils/index.html and what I have figure out so far is that I basically need to write a setup.py script. Something like: setup(name='Distutils', version='1.0', description='Python Distribution Utilities', author='My Name', author_email='My Email', url='some URL', package_dir={'': 'src'}, packages=[''], ) I would like to ensure that my program uses 2.6 interpreter library. What would be the best approach to ensure that my program uses 2.6 ? Shall I distribute python 2.6 library along with my program ? Is there any alternative approach ?

  • How would you implement API key in WCF Data Service?

    - by rushonerok
    Is there a way to require an API key in the URL / or some other way of passing the service a private key in order to grant access to the data? I have this right now... using System; using System.Data.Services; using System.Data.Services.Common; using System.Collections.Generic; using System.Linq; using System.ServiceModel.Web; using Numina.Framework; using System.Web; using System.Configuration; [System.ServiceModel.ServiceBehavior(IncludeExceptionDetailInFaults = true)] public class odata : DataService { public static void InitializeService(DataServiceConfiguration config) { config.SetEntitySetAccessRule("*", EntitySetRights.AllRead); //config.SetServiceOperationAccessRule("*", ServiceOperationRights.All); config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V2; } protected override void OnStartProcessingRequest(ProcessRequestArgs args) { HttpRequest Request = HttpContext.Current.Request; if(Request["apikey"] != ConfigurationManager.AppSettings["ApiKey"]) throw new DataServiceException("ApiKey needed"); base.OnStartProcessingRequest(args); } } ...This works but it's not perfect because you cannot get at the metadata and discover the service through the Add Service Reference explorer. I could check if $metadata is in the url but it seems like a hack. Is there a better way?

  • J2ME web service client

    - by Wasim
    Hi all , I started to use the Netbeans 6.8 web service client wizard . I created a web service (.Net web service) witch return an object Data. The Data class , contains fileds with many types : int , string , double , Person object and array of Person object. I created the J2ME client code through the wizard and every thing seems ok . I see in the Netbeans project the service and the stub . When I try to call my web service method , say Data GetData() ; Then I have a problem with parsing the returned data from the web service and the client data object . As follows : After finishing to call the web service method , in the stub code : public Data helloWorld() throws java.rmi.RemoteException { Object inputObject[] = new Object[] { }; Operation op = Operation.newInstance( _qname_operation_HelloWorld, _type_HelloWorld, _type_HelloWorldResponse ); _prepOperation( op ); op.setProperty( Operation.SOAPACTION_URI_PROPERTY, "http://tempuri.org/HelloWorld" ); Object resultObj; try { resultObj = op.invoke( inputObject ); } catch( JAXRPCException e ) { Throwable cause = e.getLinkedCause(); if( cause instanceof java.rmi.RemoteException ) { throw (java.rmi.RemoteException) cause; } throw e; } return Data_fromObject((Object[])resultObj); } private static Data Data_fromObject( Object obj[] ) { if(obj == null) return null; Data result = new Data(); result.setIntData(((Integer )obj[0]).intValue()); result.setStringData((String )obj[1]); result.setDoubleData(((Double )obj[2]).doubleValue()); return result; } I debug the code and in Run time resultObj has one element witc is an array of the Data object , so in parsing the values in the Data_fromObject method it expect many cells like we see in the code obj[0] , obj[1] , obj [2] but in realtime it has obj[0][0] , obj[0][1] , obj[0][2] What can be the problem , how can check the code generation issue ? Is it a problem with the web service side. Please help. Thanks in advance...

  • WCF 3.5 Service and multiple http bindings

    - by mortenvpdk
    Hi I can't get my WCF service to work with more than one http binding. In IIS 7 I have to bindings http:/service and http:/service.test both at port 80 In my web.config I have added the baseAddressPrefixFilters but I can't add more than one <serviceHostingEnvironment> <baseAddressPrefixFilters> <add prefix="http://service"/> <add prefix="http://service.test"/> </baseAddressPrefixFilters> </serviceHostingEnvironment> This gives almost the same error "This collection already contains an address with scheme http. There can be at most one address per scheme in this collection. " as if no filers were specified at all (This collection already contains an address with scheme http. There can be at most one address per scheme in this collection. Parameter name: item) If I add only one filter then the service works but only responds on the added filter address. I've also tried with specifing multiple endpoints like (and only one filter): <endpoint address="http://service.test" binding="basicHttpBinding" bindingConfiguration="" contract="IService" /> <endpoint address="http://service" binding="basicHttpBinding" bindingConfiguration="" contract="IService" /> Then still only the address also specified in the filter works and the other returns this error: Server Error in Application "ISPSERVICE" HTTP Error 400.0 - Bad Request Regards Morten

  • Html / Email / Distribution list problem from a noob

    - by Hezeus
    I need to create a feature for a website that will allow a user to enter their email in order to receive a free promotion (which will be emailed immediately) and be added to an announcement list. I haven't done any web programming and am wondering where I should start? Should I just create a database and everytime an email is entered, add the email to the database, then when I want to send out an announcement just write a script that will send an email to every address? Thanks!

  • ClassCastException while using service

    - by Sebi
    I defined a local Service: public class ComService extends Service implements IComService { private IBinder binder = new ComServiceBinder(); public class ComServiceBinder extends Binder implements IComService.IServiceBinder { public IComService getService() { return ComService.this; } } public void test(String msg) { System.out.println(msg); } @Override public IBinder onBind(Intent intent) { return binder; } } The corresponding interface: public interface IComService { public void test(String msg); public interface IServiceBinder { IComService getService(); } } Then i try to bind the service in another activity in another application, where the same interface is available: bindService(new Intent("ch.ifi.csg.games4blue.gamebase.api.ComService"), conn, Context.BIND_AUTO_CREATE); and private ServiceConnection conn = new ServiceConnection() { @Override public void onServiceConnected(ComponentName name, IBinder service) { Log.i("INFO", "Service bound " + name); comService = ((IComService.IServiceBinder)service).getService(); serviceHandler.sendEmptyMessage(0); } @Override public void onServiceDisconnected(ComponentName arg0) { Log.i("INFO", "Service Unbound "); } }; but the line comService = ((IComService.IServiceBinder)service).getService(); always throws a 05-02 22:12:55.922: ERROR/AndroidRuntime(622): java.lang.ClassCastException: android.os.BinderProxy I can't explain why, I followed the app sample on http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/app/LocalServiceBinding.html Any hints would be nice!

  • installer for distribution visual studio 2008 express

    - by Matt Facer
    Hi guys... I've been doing some research in to installers for visual studio express 2008. I don't much like the standard publish option. I'd rather have a proper windows installer. Am I right in thinking that the only way to do this is to upgrade to the standard edition? Are there any third party tools which can be used? I've tried googling a lot, but don't seem to be getting anywhere!

  • Algorithm for finding the best routes for food distribution in game

    - by Tautrimas
    Hello, I'm designing a city building game and got into a problem. Imagine Sierra's Caesar III game mechanics: you have many city districts with one market each. There are several granaries over the distance connected with a directed weighted graph. The difference: people (here cars) are units that form traffic jams (here goes the graph weights). Note: in Ceasar game series, people harvested food and stockpiled it in several big granaries, whereas many markets (small shops) took food from the granaries and delivered it to the citizens. The task: tell each district where they should be getting their food from while taking least time and minimizing congestions on the city's roads. Map example Sample diagram Suppose that yellow districts need 7, 7 and 4 apples accordingly. Bluish granaries have 7 and 11 apples accordingly. Suppose edges weights to be proportional to their length. Then, the solution should be something like the gray numbers indicated on the edges. Eg, first district gets 4 apples from the 1st and 3 apples from the 2nd granary, while the last district gets 4 apples from only the 2nd granary. Here, vertical roads are first occupied to the max, and then the remaining workers are sent to the diagonal paths. Question What practical and very fast algorithm should I use? I was looking at some papers (Congestion Games: Optimization in Competition etc.) describing congestion games, but could not get the big picture. Any help is very appreciated! P. S. I can post very little links and no images because of new user restriction.
