• How can I better manage far-reaching changes in my code?

  - by neuviemeporte

  In my work (writing scientific software in C++), I often get asked by the people who use the software to get their work done to add some functionality or change the way things are done and organized right now. Most of the time this is just a matter of adding a new class or a function and applying some glue to do the job, but from time to time, a seemingly simple change turns out to have far-reaching consequences that require me to redesign a substantial amount of existing code, which takes a lot of time and effort, and is difficult to evaluate in terms of time required. I don't think it has as much to do with inter-dependence of modules, as with changing requirements (admittedly, on a smaller scale). To provide an example, I was thinking about the recently-added multi-user functionality in Android. I don't know whether they planned to introduce it from the very beginning, but assuming they didn't, it seems hard to predict all the areas that will be affected by the change (apps preferences, themes, need to store account info somehow, etc...?), even though the concept seems simple enough, and the code is well-organized. How do you deal with such situations? Do you just jump in to code and then sort out the cruft later like I do? Or do you do a detailed analysis beforehand of what will be affected, what needs to be updated and how, and what has to be rewritten? If so, what tools (if any) and approaches do you use?

• Possible reasons for high CPU load of taskmgr.exe process on VM?

  - by mjn

  On a VMware virtual machine which has severe performance problems I can see a constant average of 20+ percent CPU load for the TASKMGR.EXE (task manager) process. The apps running on this server have lower load, around 4 to 10 percent average. The VM is running Windows 2003 Server Standard with 3.75 GB assigned RAM. I suspect that the task manager CPU load has something to do with other VM instances on the VMWare server but could not see a similar value on internal ESXi systems (the problematic VM runs in the customers IT).

• How to automatically start VM created by virt-manager?

  - by Jeff Shattock

  I have created a virtual machine with virt-manager that runs on kvm/qemu. The machine works well when started through virt-manager. However, I would like to be able to start and stop the VM through a script in init.d, so that it comes up and down along with the host. I need to have virt-manager show that the machine is running, and to be able to connect to its console through there. When I use the command line that is produced by running ps -eaf | grep kvm after starting the vm through virt-manager, I get some console messages about redirected character devices, but the machine does start and runs properly. However, I do not get any indication from virt-manager that it has started. How can I modify the command line to get virt-manager to pick up the running VM? Is there anything else about the command line that should change when starting outside of virt-manager? Command line is (slightly reformatted for readability): /usr/bin/kvm -S -M pc-0.12 -enable-kvm -m 512 -smp 1 -name BORON \ -uuid fa7e5fbd-7d8e-43c4-ebd9-1504a4383eb1 \ -chardev socket,id=monitor,path=/var/lib/libvirt/qemu/BORON.monitor,server,nowait \ -monitor chardev:monitor -localtime -boot c \ -drive file=/dev/FS1/BORON,if=ide,index=0,boot=on,format=raw \ -net nic,macaddr=52:54:00:20:0b:fd,vlan=0,name=nic.0 \ -net tap,fd=41,vlan=0,name=tap.0 -chardev pty,id=serial0 -serial chardev:serial0 \ -parallel none -usb -usbdevice tablet -vnc 127.0.0.1:1 -k en-us -vga cirrus

• How far should an entity take care of its properties values by itself?

  - by Kharlos Dominguez

  Let's consider the following example of a class, which is an entity that I'm using through Entity Framework. - InvoiceHeader - BilledAmount (property, decimal) - PaidAmount (property, decimal) - Balance (property, decimal) I'm trying to find the best approach to keep Balance updated, based on the values of the two other properties (BilledAmount and PaidAmount). I'm torn between two practices here: Updating the balance amount every time BilledAmount and PaidAmount are updated (through their setters) Having a UpdateBalance() method that the callers would run on the object when appropriate. I am aware that I can just calculate the Balance in its getter. However, it isn't really possible because this is an entity field that needs to be saved back to the database, where it has an actual column, and where the calculated amount should be persisted to. My other worry about the automatically updating approach is that the calculated values might be a little bit different from what was originally saved to the database, due to rounding values (an older version of the software, was using floats, but now decimals). So, loading, let's say 2000 entities from the database could change their status and make the ORM believe that they have changed and be persisted back to the database the next time the SaveChanges() method is called on the context. It would trigger a mass of updates that I am not really interested in, or could cause problems, if the calculation methods changed (the entities fetched would lose their old values to be replaced by freshly recalculated ones, simply by being loaded). Then, let's take the example even further. Each invoice has some related invoice details, which also have BilledAmount, PaidAmount and Balance (I'm simplifying my actual business case for the sake of the example, so let's assume the customer can pay each item of the invoice separately rather than as a whole). If we consider the entity should take care of itself, any change of the child details should cause the Invoice totals to change as well. In a fully automated approach, a simple implementation would be looping through each detail of the invoice to recalculate the header totals, every time one the property changes. It probably would be fine for just a record, but if a lot of entities were fetched at once, it could create a significant overhead, as it would perform this process every time a new invoice detail record is fetched. Possibly worse, if the details are not already loaded, it could cause the ORM to lazy-load them, just to recalculate the balances. So far, I went with the Update() method-way, mainly for the reasons I explained above, but I wonder if it was right. I'm noticing I have to keep calling these methods quite often and at different places in my code and it is potential source of bugs. It also has a detrimental effect on data-binding because when the properties of the detail or header changes, the other properties are left out of date and the method has no way to be called. What is the recommended approach in this case?

• Building a JMX client in a servlet installed on the Deployment Manager

  - by Trevor

  Hi guys, I'm building a monitoring application as a servlet running on my websphere 7 ND deployment manager. The tool uses JMX to query the deployment manager for various data. Global Security is enabled on the dmgr. I'm having problems getting this to work however. My first attempt was to use the websphere client code: String sslProps = "file:" + base +"/properties/ssl.client.props"; System.setProperty("com.ibm.SSL.ConfigURL", sslProps); String soapProps = "file:" + base +"/properties/soap.client.props"; System.setProperty("com.ibm.SOAP.ConfigURL", pp); Properties connectProps = new Properties(); connectProps.setProperty(AdminClient.CONNECTOR_TYPE, AdminClient.CONNECTOR_TYPE_SOAP); connectProps.setProperty(AdminClient.CONNECTOR_HOST, dmgrHost); connectProps.setProperty(AdminClient.CONNECTOR_PORT, soapPort); connectProps.setProperty(AdminClient.CONNECTOR_SECURITY_ENABLED, "true"); AdminClient adminClient = AdminClientFactory.createAdminClient(connectProps) ; This results in the following exception: Caused by: com.ibm.websphere.management.exception.ConnectorNotAvailableException: ADMC0016E: The system cannot create a SOAP connector to connect to host ssunlab10.apaceng.net at port 13903. at com.ibm.ws.management.connector.soap.SOAPConnectorClient.getUrl(SOAPConnectorClient.java:1306) at com.ibm.ws.management.connector.soap.SOAPConnectorClient.access$300(SOAPConnectorClient.java:128) at com.ibm.ws.management.connector.soap.SOAPConnectorClient$4.run(SOAPConnectorClient.java:370) at com.ibm.ws.security.util.AccessController.doPrivileged(AccessController.java:118) at com.ibm.ws.management.connector.soap.SOAPConnectorClient.reconnect(SOAPConnectorClient.java:363) ... 22 more Caused by: java.net.ConnectException: Connection refused at java.net.PlainSocketImpl.socketConnect(Native Method) at java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:333) at java.net.PlainSocketImpl.connectToAddress(PlainSocketImpl.java:195) at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:182) at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:366) at java.net.Socket.connect(Socket.java:519) at java.net.Socket.connect(Socket.java:469) at java.net.Socket.<init>(Socket.java:366) at java.net.Socket.<init>(Socket.java:209) at com.ibm.ws.management.connector.soap.SOAPConnectorClient.getUrl(SOAPConnectorClient.java:1286) ... 26 more So, I then tried to do it via RMI, but adding in the sas.client.properties to the environment, and setting the connectort type in the code to CONNECTOR_TYPE_RMI. Now though I got a NameNotFoundException out of CORBA: Caused by: javax.naming.NameNotFoundException: Context: , name: JMXConnector: First component in name JMXConnector not found. [Root exception is org.omg.CosNaming.NamingContextPackage.NotFound: IDL:omg.org/CosNaming/NamingContext/NotFound:1.0] To see if it was an IBM issue, I tried using the standard JMX connector as well with the same result (substitute AdminClient for JMXConnector in the above error) * JMXServiceURL url = new JMXServiceURL("service:jmx:rmi:///jndi/JMXConnector"); Hashtable h = new Hashtable(); String providerUrl = "corbaloc:iiop:" + dmgrHost + ":" + rmiPort + "/WsnAdminNameService"; h.put(Context.PROVIDER_URL, providerUrl); // Specify the user ID and password for the server if security is enabled on server. String[] credentials = new String[] { "***", "***" }; h.put("jmx.remote.credentials", credentials); // Establish the JMX connection. JMXConnector jmxc = JMXConnectorFactory.connect(url, h); // Get the MBean server connection instance. mbsc = jmxc.getMBeanServerConnection(); At this point, in desperation I wrote a wsadmin sccript to run both the RMI and SOAP methods. To my amazement, this works fine. So my question is, why does the code not work in a servlet installed on the dmgr ? regards, Trevor

• Task scheduler "hidden" only hides task, not process

  - by Brandi

  I am trying to make an application that acts like a desktop application for all the computers in our network. I have already got a windows forms app that works like I want it to, and I'm using the task scheduler to start it on login. We would really like it if the process as well as the task is hidden from the task manager in order to avoid accidental deletion. Selecting "Hidden" in the task scheduler hides the task (good!) but the process is still visible (not good enough). I tried using the option to run as "SYSTEM" or "LOCAL SERVICE" so that the user would get "access denied" when trying to delete or just wouldn't even view it by default. However, running as a service makes the process invisible on Vista and 7, and the point of my app is to display information interactively. (User can click, sort, etc). Is there any other alternatives to either run the process as someone/something besides the logged in user and still have the logged on user be able to see and interact with it? (Therefore it would list as someone else's app?) From what I've read on the internet, the only ways to actually hide something from the task manager seem hacky and/or difficult and rather involved. I don't really want to write a bunch of C or whatever only to maybe not have it work on Vista/7 anyway. Besides which, for a legitimate app with a legitimate use, I shouldn't have to go to those extremes... I see "Access Denied" all the time for system processes... why is it so hard for me to do the same? So does anyone have any simple solutions? Is it easier than I think to just list something in the task manager as another user? Thanks in advance for any replies.

• Authentication settings in IIS Manager versus web.config versus system.serviceModel

  - by Joe

  I'm new to ASP.NET :) I have a WCF web service, and I want to use Basic authentication. I am getting lost in the authentication options: In IIS 6 Manager, I can go in to the properties of the web site and set authentication options. In the web site's web.config file, under system.web, there is an <authentication mode="Windows"/> tag In the web site's web.config file, under system.serviceModel, I can configure: <wsHttpBinding <binding name="MyBinding" <security mode="Transport" <transport clientCredentialType="Basic"/ </security </binding </wsHttpBinding What is the difference between these three? How should each be configured? Some context: I have a simple web site project that contains a single .svc web service, and I want it to use Basic authentication over SSL. (Also, I want it to not use Windows accounts, but maybe that is another question.)

• How to retrieve path for a file embedded in Resources (Resource Manager) - .net C#

  - by curiousone

  Hi, I am trying to retrieve file path for a html file that is embedded in resource (resx file) in VS2008 C# project. I want to give path of this file to native webbrowser control (PIEHtml) to be able to navigate (DTM_NAVIGATE) in my application. I know I can pass the string to this control using DTM_ADDTEXTW but since html text size is so big, I dont want to pass string to the control. I need to somehow extract the file path for this html file embedded inside resource manager. I tried using but this does not give the file path of html inside assembly: private ResourceManager resManager = new ResourceManager("AppName.FolderName.FileName", System.Reflection.Assembly.GetExecutingAssembly()); this.lbl.Text = resManager.GetString("StringInResources"); and also read Retrieving Resources in Satellite Assemblies but it did not solve my problem. Can somebody please provide info as to how to achieve this ? thanks,

• TFS Integration with Rational ClearQuest and Requirement Manager

  - by Kangkan

  I am working on an integration approach for integrating Rationa (IBM Jazz) Requirement Manager (RM) and Clear Quest (CQ) with TFS. As the teams are moving from ClearCase to TFS, what we are looking at is still being able to manage the requirements in RM and manage testing using CQ. The flow will be something like: Requirements are planned and detailed in RM Create work items in TFS connected to the Requirements in RM Create design and code using VS2010 and managing the version control in TFS Creating test plans and test cases in CQ (connected to requirements in RM) Run test against builds in TFS Publish test results in CQ against builds in TFS Run reports in RM, CQ and TFS that links up the items across the platforms. I have started looking at TFS Integration platform. But shall like to have your guidance for an early resolution and better solution approach.

• Django model manager didn't work with related object when I do aggregated query

  Hi, all. I'm having trouble doing an aggregation query on a many-to-many related field. Let's begin with my models: class SortedTagManager(models.Manager): use_for_related_fields = True def get_query_set(self): orig_query_set = super(SortedTagManager, self).get_query_set() # FIXME `used` is wrongly counted return orig_query_set.distinct().annotate( used=models.Count('users')).order_by('-used') class Tag(models.Model): content = models.CharField(max_length=32, unique=True) creator = models.ForeignKey(User, related_name='tags_i_created') users = models.ManyToManyField(User, through='TaggedNote', related_name='tags_i_used') objects_sorted_by_used = SortedTagManager() class TaggedNote(models.Model): """Association table of both (Tag , Note) and (Tag, User)""" note = models.ForeignKey(Note) # Note is what's tagged in my app tag = models.ForeignKey(Tag) tagged_by = models.ForeignKey(User) class Meta: unique_together = (('note', 'tag'),) However, the value of the aggregated field used is only correct when the model is queried directly: for t in Tag.objects.all(): print t.used # this works correctly for t in user.tags_i_used.all(): print t.used #prints n^2 when it should give n Would you please tell me what's wrong with it?

• Get list of users belonging to a role using Authorization Manager (AzMan)

  - by Sam

  Using ASP.NET (C#) I have set up Authorization Manager to allow me to handle roles on a website. Added users to roles is simple Roles.AddUserToRole("DOMAIN\\UserName", "role"). However I want to list the users belonging to a role, but since they are stored as SID's, displaying them would not be that helpful. To get the users, I am thinking XML would have to be used, although is it possible to use COM Interop to both do that and get the user name? Either way, how can I get the users belonging to a role? The table to manage roles would basically be like this: Role User ---- ---- admin DOMAIN\UserName [delete] DOMAIN\UserName2 [delete] [add user text box] news DOMAIN\UserName3 [delete] [add user text box]

• Subclassing Satchmo's Category model, but then getting the error "'Manager' object has no attribute 'root_categories'"

  - by hellsgate

  I'm using Satchmo as part of a website I'm currently building. At the moment I'm trying add more functions to the Satchmo Category class, but obviously I'm not going to make any changes to the Satchmo files. So, I thought that subclassing the Category class would give me a new class which contains all the Satchmo Category properties and methods while allowing me to add my own. However, either Python subclassing doesn't work like that, or I am doing it wrong. Here is the code I'm using to subclass Category: from product.models import Category class MyCategory(Category): """ additional functions to pull data from the Satchmo store app """ One of the methods I can normally use from the Category class is: Category.objects.root_categories() however, when I try to access MyCategory.objects.root_categories() I get the following error: AttributeError: 'Manager' object has no attribute 'root_categories' Can anyone point me in the right direction for solving this?

• WinForms app config manager is x86 and cannot reference assemblies that targets Any CPU

  - by ivos

  Hi I'm using Win7 64x and Visual Studio 2010. I created a library/framework targeting Any CPU. Then I created a new WinForms project that uses that framework, leaving the default values of the wizard. I mean, I didn't change anything. When I reference my framework, VS cannot find the assemblies. If I go to the project properties, it is targeting Any CPU (as expected, I can change it if I want). But if I go to Configuration Manager, the only choice I have for that project is x86. And I guess that is the problem. I tried to add Any CPU as a new Target but I was unable to. Could someone help me? :) Thanks in advance!

• Paging doesn't work in the Joomla Article Manager in the admin section

  - by SkippyFire

  I inherited a Joomla site that is having a problem with the article manager in the admin section. The pagination doesn't work! If I click the page number, forward, back, or page size, nothing happens! So I found out that someone had previously installed the iJoomla SEO plugin, but it never worked so they removed it. I think it is incompatible with the version I have. I setup a local environment with almost the same setup (I have 5.2.11 vs the servers 5.2.13) with Wamp Server, and I found that some of the session variables are missing! When dumped via print_r(), the $_SESSION variable is missing the "com_content", "global", and "com_plugins" arrays! So I guess that is the reason that paging doesn't work, because the "com_content" array looks like it has paging info in it. (maybe I'm wrong) So I'm running Version 1.5.13 on PHP Version 5.2.13 Anyone know why this would happen? Thanks in advance!

• Configuration manager for PHP

  - by Jack

  I am working on code re-factoring of configuration file loading part in PHP. Earlier I was using multiple 'ini' files but now I plan to go for single XML file which will be containing all configuration details of the project. Problem is, if somebody wants configuration file in ini or DB or anything else and not the default one (in this case XML), my code should handle that part. If somebody wants to go for other configuration option like ini, he will have to create ini file similar to my XML configuration file and my configuration manager should take care everything like parsing, storing in cache. For that I need a mechanism lets say proper interface for my configuration data where the underlying data store can be anything( XML, DB, ini etc) also I don't want it to be dependent on these underlying store and anytime in future this should be extensible to other file formats.
