• PHP `virtual()` with Apache MultiViews not working after upgrade to Ubuntu 12.04

  - by Izzy

  I use PHP's virtual() directive quite a lot on one of my sites, including central elements. This worked fine for the last ~10 years -- but after upgrading (or rather moving, as it is on a new machine) to Ubuntu 12.04 it somehow got broken. Example setup (simplified) To make it easier to understand, I simplify some things (contents). So say I need a HTML fragment like <P>For further instructions, please look <A HREF='foobar'>here</P> in multiple pages. 10 years ago, I used SSI for that, so it is put into a file in a central place -- so if e.g. the targeted URL changes, I only need to update it in one place. To serve multiple languages, I have Apache's MultiViews enabled -- and at $DOCUMENT_ROOT/central/ there are the files: foobar.html (English variant, and the default) foobar.html.de (German variant). Now in the PHP code, I simply placed: <? virtual("/central/foobar"); ?> and let Apache take care to deliver the correct language variant. The problem As said, this worked fine for about 10 years: German visitors got the German variant, all others the English (depending on their preferred language). But after upgrading to Ubuntu 12.04, it no longer worked: Either nothing was delivered from the virtual() command, or (in connection with framesets) it even ended up in binary gibberish. Trying to figure out what happens, I played with a lot of things. I first thought MultiViews was (somehow) not available anymore -- but calling http://<server>/central/foobar showed the right variant, depending on the configured language preferences. This also proved there was nothing wrong with file permissions. The error.log gave no clues either (no error message thrown). Finally, just as a "last ressort", I changed the PHP command to <? virtual("central/foobar.html"); ?> -- and that very same file was in fact included. So PHP's virtual() function basically worked -- but the language dependend stuff obviously did no longer work together with it as it did before. Of course I tried to find some change (most likely in PHP's virtual() command), using Google a lot, and also searching the questions here -- unfortunately to no avail. Finally: The question Putting "design questions" aside (surely today I would design things differently -- but at least currently I miss the time to change that for a quite huge amount of pages): What can be done to make it work again? I surely missed something -- but I cannot figure out what...

• Is it possible to cause artificial network packet loss or latency?

  - by nbolton

  I'm trying to reproduce some issues on a deployed application where the MSSQL server and client are running in two separate machines. I think there may be network issues between the two machines, so I'd like to try and reproduce these conditions on two Hyper-V virtual machines (on the same virtual server). Of course, the network for these virtual machines is "local" so it's actually far from the conditions in a live environment. Is there a program I can run on either virtual machine which will degrade the network performance? Or maybe any other work arounds? For example, one way to reproduce the conditions may be to run the VMs on separate Hyper-V servers in geographically dispersed locations (so the SQL traffic goes over VPN or something) -- but this is a little long winded I think. There must be a simpler way.

• VPN connection over apache mod_proxy

  - by This is it

  Hi We have several virtual machines which are connected in a private virtual network connection. Internet access for these machines is provided via dedicated virtual machine which has apache proxy server on it (they all use this machine as proxy). The problem now is that from several machines we need to connect to external VPN Server, but it seems that VPN connections don't work over apache proxy. Any suggestions on how to enable VPN connection over apache proxy (or some other proxy)? Some other solution? Thanks

• Increase/refresh the size of the FreeBSD's main partition

  - by Lucas

  I am using VirtualBox and have my FreeBSD mounted on a virtual drive, which recently ran out of space (10 GB) so I have increased the Virtual Drive size up to the 15 GB - started my FreeBSD and its still out of space, because it doesnt "refresh" the main partition size: # df -h Filesystem Size Used Avail Capacity Mounted on /dev/ada0p2 9.3G 9.3G -711M 108% / devfs 1.0k 1.0k 0B 100% /dev How can I set the partition size to the virtual drive size?

• Is there a postfix mysql virtual_maps append_at_origin workaround so I can pipe to external scripts?

  - by FilmJ

  I am using virtual domains, and I'd like to setup the server to alias to custom scripts. I manage all accounts using postfix mappings to mysql. It seems that postfix automatically appends a virtual domain regardless of how the forwarded/aliased result comes back. So even though i have: "|/bin/command" postfix is reading it as: "|/bin/command"@mydomain.com Is there any work-around, or setting I can fix? It would seem than append_at_myorigin=no would be ideal, but that's unsupported according to the documentation. Another option, maybe I can skip virtual aliases altogether and use the "/etc/postfix/aliases" table - assuming all emails go to the main domain. I'll try this, but if anyone has any other ideas how to make it work with virtual domains, please let me know as this would be very useful! Thanks.

• Azure Linux out of band managment

  - by faker

  I have a Linux (Ubuntu) virtual machine running on Azure. It seems like the only way to connect to it is via SSH. This is OK for normal operation, but what to do when something goes wrong (fsck waiting for user-input, new kernel doesn't boot, mis-configured network, etc.)? There is a grayed out "Connect" button in the management interface, and the help for it says: To access a virtual machine running Windows Server, click Connect and follow the instructions. Enter the password that was set when the virtual machine was created. The Connect button is not available for a virtual machine running Linux, but you can use your favorite SSH program to access it. I've read the documentation on the command line tools, but there is also no way to connect to it. Is there any way for me to get such a console?

• Hyper-V Manager - Host Access During a Catastrophe

  - by LonnieBest

  How can I ensure that I can always have Hyper-V Manager access to a Hyper-V server, even in the event that the Active Directory Server is down (in a domain-login environment)? Background: The one that came before me, set up the company's servers as virtual machines on top of a host running Hyper-V Server 6.1 (7601) Service Pack 1. For managing Hyper-V, he installed Window 7 onto a virtual machine (run on the same host) with Hyper-V Manager installed. When the (virtual) Active Directory server (run on this same host) is rebooted, during that reboot, I'm unable to RDP into the Windows 7 virtual machine, and I'm therefore unable to access Hyper-V Manager when the Active Directory server is down. I suspect I can't login because I can't authenticate with the Active Directory Server. I'm going to install Hyper-V Manger onto some addition manager's workstations, but how can I ensure they'll have access in a catastrophe where Active Directory authentication isn't possible?

• VMWare Player does not save changes in guest operating system

  - by Giorgos Manoltzas

  I have installed VMWare Player in my Windows 7 Ultimate and I have added Ubuntu 12.10 in a virtual machine. The problem is that every time I power off the virtual machine everything is lost. I mean every program I install or folder i save or anything else is lost completely. And when I start the again the virtual machine is like newly installed. Is there an option to change this (strange) behaviour?

• Ubuntu: Resize the root LVM(2?) partition

  - by user12259

  I have an Ubuntu virtual machine running in VirtualBox 2.2.4, and I created it on an 8gb virtual disk which is too small. So, I am trying to increase the size of the disk. So far, I have done this: Created a new larger virtual disk Added the 2nd disk to the machine Used CloneZilla to clone the first disk onto the 2nd disk Removed the first disk Booted up off the 2nd (larger disk) But now I'm still stuck with an 8gb partition on my new 100gb virtual disk. Whats the easiest path from here to having a 100gb partition? :) I gather GPart can resize partitions, but it doesn't seem to support LVM2 partitions, which mine seems to be. thx Alex

• fluent nhibernate one to many mapping

  - by Sammy

  I am trying to figure out what I thought was just a simple one to many mapping using fluent Nhibernate. I hoping someone can point me to the right directory to achieve this one to many relations I have an articles table and a categories table Many Articles can only belong to one Category Now my Categores table has 4 Categories and Articles has one article associated with cateory1 here is my setup. using FluentNHibernate.Mapping; using System.Collections; using System.Collections.Generic; namespace FluentMapping { public class Article { public virtual int Id { get; private set; } public virtual string Title { get; set; } public virtual Category Category{get;set;} } public class Category { public virtual int Id { get; private set; } public virtual string Description { get; set; } public virtual IList<Article> Articles { get; set; } public Category() { Articles=new List<Article>(); } public virtual void AddArticle(Article article) { article.Category = this; Articles.Add(article); } public virtual void RemoveArticle(Article article) { Articles.Remove(article); } } public class ArticleMap:ClassMap<Article> { public ArticleMap() { Table("Articles"); Id(x => x.Id).GeneratedBy.Identity(); Map(x => x.Title); References(x => x.Category).Column("CategoryId").LazyLoad(); } public class CategoryMap:ClassMap<Category> { public CategoryMap() { Table("Categories"); Id(x => x.Id).GeneratedBy.Identity(); Map(x => x.Description); HasMany(x => x.Articles).KeyColumn("CategoryId").Fetch.Join(); } } } } if I run this test [Fact] public void Can_Get_Categories() { using (var session = SessionManager.Instance.Current) { using (var transaction = session.BeginTransaction()) { var categories = session.CreateCriteria(typeof(Category)) //.CreateCriteria("Articles").Add(NHibernate.Criterion.Restrictions.EqProperty("Category", "Id")) .AddOrder(Order.Asc("Description")) .List<Category>(); } } } I am getting 7 Categories due to Left outer join used by Nhibernate any idea what I am doing wrong in here? Thanks [Solution] After a couple of hours reading nhibernate docs I here is what I came up with var criteria = session.CreateCriteria(typeof (Category)); criteria.AddOrder(Order.Asc("Description")); criteria.SetResultTransformer(new DistinctRootEntityResultTransformer()); var cats1 = criteria.List<Category>(); Using Nhibernate linq provider var linq = session.Linq<Category>(); linq.QueryOptions.RegisterCustomAction(c => c.SetResultTransformer(new DistinctRootEntityResultTransformer())); var cats2 = linq.ToList();

• Fluent NHibermate and Polymorphism and a Newbie!

  - by Andy Baker

  I'm a fluent nhibernate newbie and I'm struggling mapping a hierarchy of polymorhophic objects. I've produced the following Model that recreates the essence of what I'm doing in my real application. I have a ProductList and several specialised type of products; public class MyProductList { public virtual int Id { get; set; } public virtual string Name {get;set;} public virtual IList<Product> Products { get; set; } public MyProductList() { Products = new List<Product>(); } } public class Product { public virtual int Id { get; set; } public virtual string ProductDescription {get;set;} } public class SizedProduct : Product { public virtual decimal Size {get;set;} } public class BundleProduct : Product { public virtual Product BundleItem1 {get;set;} public virtual Product BundleItem2 {get;set;} } Note that I have a specialised type of Product called BundleProduct that has two products attached. I can add any of the specialised types of product to MyProductList and a bundle Product can be made up of any of the specialised types of product too. Here is the fluent nhibernate mapping that I'm using; public class MyListMap : ClassMap<MyList> { public MyListMap() { Id(ml => ml.Id); Map(ml => ml.Name); HasManyToMany(ml => ml.Products).Cascade.All(); } } public class ProductMap : ClassMap<Product> { public ProductMap() { Id(prod => prod.Id); Map(prod => prod.ProductDescription); } } public class SizedProductMap : SubclassMap<SizedProduct> { public SizedProductMap() { Map(sp => sp.Size); } } public class BundleProductMap : SubclassMap<BundleProduct> { public BundleProductMap() { References(bp => bp.BundleItem1).Cascade.All(); References(bp => bp.BundleItem2).Cascade.All(); } } I haven't configured have any reverse mappings, so a product doesn't know which Lists it belongs to or which bundles it is part of. Next I add some products to my list; MyList ml = new MyList() { Name = "Example" }; ml.Products.Add(new Product() { ProductDescription = "PSU" }); ml.Products.Add(new SizedProduct() { ProductDescription = "Extension Cable", Size = 2.0M }); ml.Products.Add(new BundleProduct() { ProductDescription = "Fan & Cable", BundleItem1 = new Product() { ProductDescription = "Fan Power Cable" }, BundleItem2 = new SizedProduct() { ProductDescription = "80mm Fan", Size = 80M } }); When I persist my list to the database and reload it, the list itself contains the items I expect ie MyList[0] has a type of Product, MyList[1] has a type of SizedProduct, and MyList[2] has a type of BundleProduct - great! If I navigate to the BundleProduct, I'm not able to see the types of Product attached to the BundleItem1 or BundleItem2 instead they are always proxies to the Product - in this example BundleItem2 should be a SizedProduct. Is there anything I can do to resove this either in my model or the mapping? Thanks in advance for your help.

• Saving child collections with NHibernate

  - by Ben

  Hi, I am in the process or learning NHibernate so bare with me. I have an Order class and a Transaction class. Order has a one to many association with transaction. The transaction table in my database has a not null constraint on the OrderId foreign key. Order class: public class Order { public virtual Guid Id { get; set; } public virtual DateTime CreatedOn { get; set; } public virtual decimal Total { get; set; } public virtual ICollection<Transaction> Transactions { get; set; } public Order() { Transactions = new HashSet<Transaction>(); } } Order Mapping: <class name="Order" table="Orders"> <cache usage="read-write"/> <id name="Id"> <generator class="guid"/> </id> <property name="CreatedOn" type="datetime"/> <property name="Total" type="decimal"/> <set name="Transactions" table="Transactions" lazy="false" inverse="true"> <key column="OrderId"/> <one-to-many class="Transaction"/> </set> Transaction Class: public class Transaction { public virtual Guid Id { get; set; } public virtual DateTime ExecutedOn { get; set; } public virtual bool Success { get; set; } public virtual Order Order { get; set; } } Transaction Mapping: <class name="Transaction" table="Transactions"> <cache usage="read-write"/> <id name="Id" column="Id" type="Guid"> <generator class="guid"/> </id> <property name="ExecutedOn" type="datetime"/> <property name="Success" type="bool"/> <many-to-one name="Order" class="Order" column="OrderId" not-null="true"/> Really I don't want a bidirectional association. There is no need for my transaction objects to reference their order object directly (I just need to access the transactions of an order). However, I had to add this so that Order.Transactions is persisted to the database: Repository: public void Update(Order entity) { using (ISession session = NHibernateHelper.OpenSession()) { using (ITransaction transaction = session.BeginTransaction()) { session.Update(entity); foreach (var tx in entity.Transactions) { tx.Order = entity; session.SaveOrUpdate(tx); } transaction.Commit(); } } } My problem is that this will then issue an update for every transaction on the order collection (regardless of whether it has changed or not). What I was trying to get around was having to explicitly save the transaction before saving the order and instead just add the transactions to the order and then save the order: public void Can_add_transaction_to_existing_order() { var orderRepo = new OrderRepository(); var order = orderRepo.GetById(new Guid("aa3b5d04-c5c8-4ad9-9b3e-9ce73e488a9f")); Transaction tx = new Transaction(); tx.ExecutedOn = DateTime.Now; tx.Success = true; order.Transactions.Add(tx); orderRepo.Update(order); } Although I have found quite a few articles covering the set up of a one-to-many association, most of these discuss retrieving of data and not persisting back. Many thanks, Ben

• S#harp architecture mapping many to many and ado.net data services: A single resource was expected f

  - by Leg10n

  Hi, I'm developing an application that reads data from a SQL server database (migrated from a legacy DB) with nHibernate and s#arp architecture through ADO.NET Data services. I'm trying to map a many-to-many relationship. I have a Error class: public class Error { public virtual int ERROR_ID { get; set; } public virtual string ERROR_CODE { get; set; } public virtual string DESCRIPTION { get; set; } public virtual IList<ErrorGroup> GROUPS { get; protected set; } } And then I have the error group class: public class ErrorGroup { public virtual int ERROR_GROUP_ID {get; set;} public virtual string ERROR_GROUP_NAME { get; set; } public virtual string DESCRIPTION { get; set; } public virtual IList<Error> ERRORS { get; protected set; } } And the overrides: public class ErrorGroupOverride : IAutoMappingOverride<ErrorGroup> { public void Override(AutoMapping<ErrorGroup> mapping) { mapping.Table("ERROR_GROUP"); mapping.Id(x => x.ERROR_GROUP_ID, "ERROR_GROUP_ID"); mapping.IgnoreProperty(x => x.Id); mapping.HasManyToMany<Error>(x => x.Error) .Table("ERROR_GROUP_LINK") .ParentKeyColumn("ERROR_GROUP_ID") .ChildKeyColumn("ERROR_ID").Inverse().AsBag(); } } public class ErrorOverride : IAutoMappingOverride<Error> { public void Override(AutoMapping<Error> mapping) { mapping.Table("ERROR"); mapping.Id(x => x.ERROR_ID, "ERROR_ID"); mapping.IgnoreProperty(x => x.Id); mapping.HasManyToMany<ErrorGroup>(x => x.GROUPS) .Table("ERROR_GROUP_LINK") .ParentKeyColumn("ERROR_ID") .ChildKeyColumn("ERROR_GROUP_ID").AsBag(); } } When I view the Data service in the browser like: http://localhost:1905/DataService.svc/Errors it shows the list of errors with no problems, and using it like http://localhost:1905/DataService.svc/Errors(123) works too. The Problem When I want to see the Errors in a group or the groups form an error, like: "http://localhost:1905/DataService.svc/Errors(123)?$expand=GROUPS" I get the XML Document, but the browser says: The XML page cannot be displayed Cannot view XML input using XSL style sheet.

• How to select chosen columns from two different entities into one DTO using NHibernate?

  - by Pawel Krakowiak

  I have two classes (just recreating the problem): public class User { public virtual int Id { get; set; } public virtual string FirstName { get; set; } public virtual string LastName { get; set; } public virtual IList<OrgUnitMembership> OrgUnitMemberships { get; set; } } public class OrgUnitMembership { public virtual int UserId { get; set; } public virtual int OrgUnitId { get; set; } public virtual DateTime JoinDate { get; set; } public virtual DateTime LeaveDate { get; set; } } There's a Fluent NHibernate map for both, of course: public class UserMapping : ClassMap<User> { public UserMapping() { Table("Users"); Id(e => e.Id).GeneratedBy.Identity(); Map(e => e.FirstName); Map(e => e.LastName); HasMany(x => x.OrgUnitMemberships) .KeyColumn(TypeReflector<OrgUnitMembership> .GetPropertyName(p => p.UserId))).ReadOnly().Inverse(); } } public class OrgUnitMembershipMapping : ClassMap<OrgUnitMembership> { public OrgUnitMembershipMapping() { Table("OrgUnitMembership"); CompositeId() .KeyProperty(x=>x.UserId) .KeyProperty(x=>x.OrgUnitId); Map(x => x.JoinDate); Map(x => x.LeaveDate); References(oum => oum.OrgUnit) .Column(TypeReflector<OrgUnitMembership> .GetPropertyName(oum => oum.OrgUnitId)).ReadOnly(); References(oum => oum.User) .Column(TypeReflector<OrgUnitMembership> .GetPropertyName(oum => oum.UserId)).ReadOnly(); } } What I want to do is to retrieve some users based on criteria, but I would like to combine all columns from the Users table with some columns from the OrgUnitMemberships table, analogous to a SQL query: select u.*, m.JoinDate, m.LeaveDate from Users u inner join OrgUnitMemberships m on u.Id = m.UserId where m.OrgUnitId = :ouid I am totally lost, I tried many different options. Using a plain SQL query almost works, but because there are some nullable enums in the User class AliasToBean fails to transform, otherwise wrapping a SQL query would work like this: return Session .CreateSQLQuery(sql) .SetParameter("ouid", orgUnitId) .SetResultTransformer(Transformers.AliasToBean<UserDTO>()) .List<UserDTO>() I tried the code below as a test (a few different variants), but I'm not sure what I'm doing. It works partially, I get instances of UserDTO back, the properties coming from OrgUnitMembership (dates) are filled, but all properties from User are null: User user = null; OrgUnitMembership membership = null; UserDTO dto = null; var users = Session.QueryOver(() => user) .SelectList(list => list .Select(() => user.Id) .Select(() => user.FirstName) .Select(() => user.LastName)) .JoinAlias(u => u.OrgUnitMemberships, () => membership) //.JoinQueryOver<OrgUnitMembership>(u => u.OrgUnitMemberships) .SelectList(list => list .Select(() => membership.JoinDate).WithAlias(() => dto.JoinDate) .Select(() => membership.LeaveDate).WithAlias(() => dto.LeaveDate)) .TransformUsing(Transformers.AliasToBean<UserDTO>()) .List<UserDTO>();

• Communication Between Your PC and Azure VM via Windows Azure Connect

  - by Shaun

  With the new release of the Windows Azure platform there are a lot of new features available. In my previous post I introduced a little bit about one of them, the remote desktop access to azure virtual machine. Now I would like to talk about another cool stuff – Windows Azure Connect.   What’s Windows Azure Connect I would like to quote the definition of the Windows Azure Connect in MSDN With Windows Azure Connect, you can use a simple user interface to configure IP-sec protected connections between computers or virtual machines (VMs) in your organization’s network, and roles running in Windows Azure. IP-sec protects communications over Internet Protocol (IP) networks through the use of cryptographic security services. There’s an image available at the MSDN as well that I would like to forward here As we can see, using the Windows Azure Connect the Worker Role 1 and Web Role 1 are connected with the development machines and database servers which some of them are inside the organization some are not. With the Windows Azure Connect, the roles deployed on the cloud could consume the resource which located inside our Intranet or anywhere in the world. That means the roles can connect to the local database, access the local shared resource such as share files, folders and printers, etc.   Difference between Windows Azure Connect and AppFabric It seems that the Windows Azure Connect are duplicated with the Windows Azure AppFabric. Both of them are aiming to solve the problem on how to communication between the resource in the cloud and inside the local network. The table below lists the differences in my understanding. Category Windows Azure Connect Windows Azure AppFabric Purpose An IP-sec connection between the local machines and azure roles. An application service running on the cloud. Connectivity IP-sec, Domain-joint Net Tcp, Http, Https Components Windows Azure Connect Driver Service Bus, Access Control, Caching Usage Azure roles connect to local database server Azure roles use local shared files,  folders and printers, etc. Azure roles join the local AD. Expose the local service to Internet. Move the authorization process to the cloud. Integrate with existing identities such as Live ID, Google ID, etc. with existing local services. Utilize the distributed cache.   And also some scenarios on which of them should be used. Scenario Connect AppFabric I have a service deployed in the Intranet and I want the people can use it from the Internet.   Y I have a website deployed on Azure and need to use a database which deployed inside the company. And I don’t want to expose the database to the Internet. Y   I have a service deployed in the Intranet and is using AD authorization. I have a website deployed on Azure which needs to use this service. Y   I have a service deployed in the Intranet and some people on the Internet can use it but need to be authorized and authenticated.   Y I have a service in Intranet, and a website deployed on Azure. This service can be used from Internet and that website should be able to use it as well by AD authorization for more functionalities. Y Y   How to Enable Windows Azure Connect OK we talked a lot information about the Windows Azure Connect and differences with the Windows Azure AppFabric. Now let’s see how to enable and use the Windows Azure Connect. First of all, since this feature is in CTP stage we should apply before use it. On the Windows Azure Portal we can see our CTP features status under Home, Beta Program page. You can send the apply to join the Beta Programs to Microsoft in this page. After a few days the Microsoft will send an email to you (the email of your Live ID) when it’s available. In my case we can see that the Windows Azure Connect had been activated by Microsoft and then we can click the Connect button on top, or we can click the Virtual Network item from the left navigation bar.   The first thing we need, if it’s our first time to enter the Connect page, is to enable the Windows Azure Connect. After that we can see our Windows Azure Connect information in this page.   Add a Local Machine to Azure Connect As we explained below the Windows Azure Connect can make an IP-sec connection between the local machines and azure role instances. So that we firstly add a local machine into our Azure Connect. To do this we will click the Install Local Endpoint button on top and then the portal will give us an URL. Copy this URL to the machine we want to add and it will download the software to us. This software will be installed in the local machines which we want to join the Connect. After installed there will be a tray-icon appeared to indicate this machine had been joint our Connect. The local application will be refreshed to the Windows Azure Platform every 5 minutes but we can click the Refresh button to let it retrieve the latest status at once. Currently my local machine is ready for connect and we can see my machine in the Windows Azure Portal if we switched back to the portal and selected back Activated Endpoints node.   Add a Windows Azure Role to Azure Connect Let’s create a very simple azure project with a basic ASP.NET web role inside. To make it available on Windows Azure Connect we will open the azure project property of this role from the solution explorer in the Visual Studio, and select the Virtual Network tab, check the Activate Windows Azure Connect. The next step is to get the activation token from the Windows Azure Portal. In the same page there is a button named Get Activation Token. Click this button then the portal will display the token to me. We copied this token and pasted to the box in the Visual Studio tab. Then we deployed this application to azure. After completed the deployment we can see the role instance was listed in the Windows Azure Portal - Virtual Connect section.   Establish the Connect Group The final task is to create a connect group which contains the machines and role instances need to be connected each other. This can be done in the portal very easy. The machines and instances will NOT be connected until we created the group for them. The machines and instances can be used in one or more groups. In the Virtual Connect section click the Groups and Roles node from the left side navigation bar and clicked the Create Group button on top. This will bring up a dialog to us. What we need to do is to specify a group name, description; and then we need to select the local computers and azure role instances into this group. After the Azure Fabric updated the group setting we can see the groups and the endpoints in the page. And if we switch back to the local machine we can see that the tray-icon have been changed and the status turned connected. The Windows Azure Connect will update the group information every 5 minutes. If you find the status was still in Disconnected please right-click the tray-icon and select the Refresh menu to retrieve the latest group policy to make it connected.   Test the Azure Connect between the Local Machine and the Azure Role Instance Now our local machine and azure role instance had been connected. This means each of them can communication to others in IP level. For example we can open the SQL Server port so that our azure role can connect to it by using the machine name or the IP address. The Windows Azure Connect uses IPv6 to connect between the local machines and role instances. You can get the IP address from the Windows Azure Portal Virtual Network section when select an endpoint. I don’t want to take a full example for how to use the Connect but would like to have two very simple tests. The first one would be PING.   When a local machine and role instance are connected through the Windows Azure Connect we can PING any of them if we opened the ICMP protocol in the Filewall setting. To do this we need to run a command line before test. Open the command window on the local machine and the role instance, execute the command as following netsh advfirewall firewall add rule name="ICMPv6" dir=in action=allow enable=yes protocol=icmpv6 Thanks to Jason Chen, Patriek van Dorp, Anton Staykov and Steve Marx, they helped me to enable  the ICMPv6 setting. For the full discussion we made please visit here. You can use the Remote Desktop Access feature to logon the azure role instance. Please refer my previous blog post to get to know how to use the Remote Desktop Access in Windows Azure. Then we can PING the machine or the role instance by specifying its name. Below is the screen I PING my local machine from my azure instance. We can use the IPv6 address to PING each other as well. Like the image following I PING to my role instance from my local machine thought the IPv6 address.   Another example I would like to demonstrate here is folder sharing. I shared a folder in my local machine and then if we logged on the role instance we can see the folder content from the file explorer window.   Summary In this blog post I introduced about another new feature – Windows Azure Connect. With this feature our local resources and role instances (virtual machines) can be connected to each other. In this way we can make our azure application using our local stuff such as database servers, printers, etc. without expose them to Internet.   Hope this helps, Shaun All documents and related graphics, codes are provided "AS IS" without warranty of any kind.

  With the MEET Windows Azure event on 7th June, there are many new features and updates in windows azure platform. In the coming several posts I will try to cover some of them. And in the first post here I would like to just have a quick walkthrough of the new preview developer portal.   History of the Developer Portal If you have been working with windows azure since 2009 or 2010, you should remember the first version of the developer portal. It was built in HTML with very limited features. I have the impression when I was using is old one. The layout is not that attractive and you have very limited features. On November, 2010 alone with the SDK 1.3 release, the developer portal was getting a big jump. In order to give more usability and features this it turned to be built on Silverlight. Hence it runs like a desktop application with many windows, lists, commands and context menus. From 2010 till now many features were involved into this portal, such as the remote desktop, co-admin, virtual connect, VM role, etc.. And the portal itself became more and more complicated. But it brought some problems by using the Silverlight. The first one is the browser capability. As you know in most mobile and tablet device the browser doesn’t allow the rich content plugin, such as Flash and Silverlight. This means people cannot open and configure their azure services from their iPad, iPhone and Windows Phone, etc., even though what they need may just be restart a hosted service, or view the status of their databases. Another problem is the performance. Silverlight provides rich experience to the users, but also needs more bandwidth. So in this upgrade the preview developer portal will be back to use HTML, with JavaScript, as a mobile friendly, cross browser, interactively web site.   Preview Portal vs. Silverlight Portal Before I started to talk about the new preview portal I’d better highlight that, this preview portal is a PREVIEW version, which means even though you can do almost all features that already in the old one, as long as some cool new features I will mention in the coming several posts, there are something still under developed and migrated. So sometimes you need to switch back to the old one. For example, in preview portal there is no co-admin manage function, no remote desktop function and the SQL database manage function will take you back to the old SQL Azure Manage Portal. But as Microsoft said these missing features will be moved in the preview portal in the couple of next few months. Since the public URL of the developer portal, https://windows.azure.com/, had been changed to point to this preview one, you need to click to preview button on top of the page and click the “Take me to the previous portal” link.   Overview There are four parts in the preview portal. On the top is the header which shows the account you are currently logging in. If you click on the header it will show the top menu of windows azure, where you can navigate to the windows azure home page, the price information page, community and account, etc.. The navigation bar is on the left hand side, with the categories listed below. ALL ITEMS All items in your windows azure account, includes the web sites, services, databases, etc.. WEB SITES The web sites in your windows azure account. It will only show the web sites you have. The linked resources will be shown if you drill down into a web site. VIRTUAL MACHINES The virtual machines that you had been deployed to azure. CLOUD SERVICES All windows azure hosted services in your account. SQL DATABASES All SQL databases (SQL Azure) in your account. STORAGE All windows azure storage services in your account. NETWORKS The virtual network (Windows Azure Connect) you had been created. The available items will be listed in the main part of the page based on which category your currently selected. If there’s no item it will show the link to you to quick create. At the bottom of the page there will be the command and information bar. Based on what is selected and what is performed by the user, it will show the related information and commands. For example, in the image below when I was creating a new web site, the information bar told me that my web site is being provisioned; and there are two commands in the command bar. And once it ready the command bar will show some commands that I can do to my new web site. The “Web Sites” is a new feature introduced alone with this upgrade. It gives us an easier and quicker way to establish a website from the scratch or from some existing library. I will introduce it more details in the coming next post. Also in the command bar you can create a service by clicking the NEW button. It will slide the creation panel up to you.   Where’s My Hosted Services The Windows Azure Hosted Services had been renamed to the Cloud Services. Create a new service would be very easy. Just click the NEW button at the bottom of the page, and select the CLOUD SERVICE and QIUICK CREATE. This will create a blank hosted service without deployment and certificate. It just needs you to specify the service URL and the affinity/region. Then the service will be shown in the list. If you clicked the item all information will be shown in the main part. Since there’s no package deployed to this service so currently we cannot see any information about it. But we can upload the package by using the command at the bottom. And as you can see, we could manage the configuration, instances, certificates and we can scale up and down (change the VM size), in and out (increase and decrease the instance count) to our service. Assuming I had created an ASP.NET MVC 3 web role project in Visual Studio and completed the package. Then I can click the UPLOAD button in this page to deploy my package. In the popping up window I just specify my deployment name, package file and configure file. Also I can check the box below so that it will NOT warn me if only one instance of this deployment. Once we clicked the OK button our package will be uploaded and provisioned by the platform. After a while we can see the service was ready from the information bar. We can have the basic information about this service and deployment if we to the dashboard page. For example the usage overview diagram, status, URL, public IP address, etc.. In the configure page we can view and change the CSCFG content such as the monitor setting, connection strings, OS family. In scale page we can increase and decrease the count of the instances. And in the instances page we can view all instances status. And, if your services is using some SQL databases and storages they will be shown as the linked resources under the linked resources page. And you can manage the certificates of this service as well under the certificates page.   How About My Storage Services The storage service can be managed by clicking into the STORAGES link in the navigation bar. And we can create a new storage service from the NEW button. After specify the storage name and region it will be previsioned by the platform. If you want to copy or manage the storage key you can just click the Manage Keys button at the bottom, which is very easy. What I want to highlight here is that, you can monitor your storage service by enabling the monitor configuration. Click the storage item in the list and navigate to the configure page. As you can see in the page you can enable the monitoring for blob, table and queue. And you can also enable the logging when any requests come to the storage. But as the tooltip shown in the page, enabling the monitoring and logging will increase the usage of the storage, which means increase the bill of them. So make sure you enable them properly.   And My SQL Databases (SQL Azure) The last thing I want to quick introduce is the SQL databases, which was formally named SQL Azure. You can create a new SQL Database Server and a new database by clicking the ADD button under the SQL Database navigation item. In the popping up windows just specify the database name, the edition, size, collation and the server. You can select an existing SQL Database Server if you have, or cerate a new one. If you selected to create a new server, there will be another step you need to do, which is specify the server login, password and the region. Once it ready you can mange your databases as well as the servers in the portal. In a particular server you can update the firewall settings in its Configure page. So, What Else There are some other area on the preview portal I didn’t cover, such as the virtual machines, virtual network and web sites. Regarding the virtual machines and web sites I will talk about them in the future separated post. Regarding the virtual network, it the Windows Azure Connect we are familiar with. But as I mention in the beginning of this post, the preview portal is still under developed. Some features are not available here. For example, you cannot manage the co-admin of your subscriptions, you cannot open the remote desktop on your hosted services, and you cannot navigate to the Windows Azure Service Bus, Access Control and Caching, which formally named Windows Azure AppFabric directly. In these cases you need to navigate back to the old portal. So in the coming several months we might need to use both these two sites.   Summary In this post I quick introduced the new windows azure developer portal. Since it had been rearranged and renamed I demonstrated some features that existing in the old portal, such as how to create and deploy a hosted service, how to provision a storage service and SQL database. All features in the old portal had been, is being and will be migrated into this new portal, but some of them were in a different category and page we need to figure out.   Hope this helps, Shaun All documents and related graphics, codes are provided "AS IS" without warranty of any kind.

• Hancon / Hanwang Graphics Tablet not recognised

  - by Martin Kyle

  I'm totally lost. I've just built a new system and installed Ubuntu 12.04. It's my first time with Linux and getting into the terminal / command line for the first time since IBMDOS 5 and Windows 3.1 has been a steep learning curve. However, the interface works beautifully apart from it doesn't recognize my Hanvon Artmaster AM1209. I have sent diagnostics to Digimend and Favux was kind enough to advise that the tablet should be using the Wacom X driver as the Hanvon is actually a Hanwang and these should be supported. lsusb reports: ID 0b57:8501 Beijing HanwangTechnology Co., Ltd xinput list reports: ? Virtual core pointer id=2 [master pointer (3)] ? ? Virtual core XTEST pointer id=4 [slave pointer (2)] ? ? PS/2+USB Mouse id=8 [slave pointer (2)] ? Virtual core keyboard id=3 [master keyboard (2)] ? Virtual core XTEST keyboard id=5 [slave keyboard (3)] ? Power Button id=6 [slave keyboard (3)] ? Power Button id=7 [slave keyboard (3)] ? Eee PC WMI hotkeys id=9 [slave keyboard (3)] ? AT Translated Set 2 keyboard id=10 [slave keyboard (3)] Favux suggested inspecting /var/log/Xorg.0.log for the tablet but I cannot see any mention of it, and that is as far as I have got. I've tried researching the problem but I am struggling with all the new terminology and the fact that I want the PC to be a means to an end and not the end in itself where I spend the rest of my days tweaking and testing rather than just using it. Hope there is some help out there.

• How to mark dependencies as solved?

  - by joo

  On my Ubuntu I needed to install a newer version of erlang. Then I installed rabbitmq-server with dpkg --force-depends -i rabbitmq-server_2.1.1-1_all.deb And everything worked fine, till... Now I have the following problem when doing an apt-get install or upgrade: rabbitmq-server: Depends: erlang-base (>= 1:12.b.3) but it is not installable or erlang-base-hipe (>= 1:12.b.3) but it is not installable Depends: erlang-ssl which is a virtual package. or erlang-nox (< 1:13.b-dfsg1-1) but it is not installable Depends: erlang-os-mon which is a virtual package. or erlang-nox (< 1:13.b-dfsg1-1) but it is not installable Depends: erlang-mnesia which is a virtual package. or erlang-nox (< 1:13.b-dfsg1-1) but it is not installable Depends: erlang-inets which is a virtual package. or erlang-nox (< 1:13.b-dfsg1-1) but it is not installable Remove the following packages: rabbitmq-server Score is 121 Accept this solution? [Y/n/q/?] What command tells apt to resolve dependencies without removing the package? Thanks a lot in advance...

• How to implement a stack of game states in C++

  - by Lisandro Vaccaro

  I'm new to C++ and as a college proyect I'm building a 2D platformer with some classmates, I recently read that it's a good idea to have a stack of gamestates instead of a single global variable with the game state (which is what I have now) but I'm not sure how to do it. Currently this is my implementation: class GameState { public: virtual ~GameState(){}; virtual void handle_events() = 0; virtual void logic() = 0; virtual void render() = 0; }; class Menu : public GameState { public: Menu(); ~Menu(); void handle_events(); void logic(); void render(); }; Then I have a global variable of type GameState: GameState *currentState = NULL; And in my Main I define the currentState and call it's methods: int main(){ currentState = new Menu(); currentState.handle_events(); } How can I implement a stack or something similar to go from that to something like this: int main(){ statesStack.push(new Menu()); statesStack.getTop().handle_events(); }

• Unable to install Ubuntu 12.04.1 on Virtualbox on Windows 7 Host

  - by arcube

  I would like to install Ubuntu 12.04.1 in a virtual box on windows 7 host however I get a black screen after selecting to install Ubuntu i.e. right after choosing English language I have tried the 32bit and 64bit version desktop version, have also read thru some guides e.g. http://www.psychocats.net/ubuntu/virtualbox but I could not find any solution to fix this problem. BTW I have Ubuntu installed using Virtual PC (not running at the same time), also I have mac OS (mountain lion) installed using Virtual Box so I do not think it is a problem with the virtual box or windows 7 host. My VM configuration is with 1 core and 1 GB of ram using 20GB VDI; rest is default config. My hardware is Core i7 3770k / Asus P8Z77-V Deluxe / GSkill 32GB which I believe should be more than sufficient to run another VM. I have moved my user profile from SSD to HDD via junction however IMHO it should not matter. Has anyone else come across this problem and found a solution? Any help/thoughts on how to solve this would be very much appreciated.

• SSMS hanging without error when connecting to SQL

  - by Rob Farley

  Scary day for me last Thursday. I had gone up to Brisbane, and was due to speak at the Queensland SQL User Group on Thursday night. Unfortunately, disaster struck about an hour beforehand. Nothing to do with the recent floods (although we were meeting in a different location because of them). It was actually down to the fact that I’d been fiddling with my machine to get Virtual Server running on Windows 7, and SQL had finally picked up a setting from then. I could run Management Studio, but it couldn’t connect at all. No error, it just seemed to hang. One of the things you have to do to get Virtual Server installed is to tweak the Group Policy settings. I’d used gpupdate /force to get Windows to pick up the new setting, which allowed me to get Virtual Server running properly, but at the time, SQL was still using the previous settings. Finally when in Brisbane, my machine picked up the new settings, and caused me pain. Dan Benediktson describes the situation. If the SQL client picks up the wrong value out of the GetOverlappedResult API (which is required for various changes in Windows 7 behaviour), then Virtual Server can be installed, but SQL Server won’t allow connections. Yay. Luckily, it’s easy enough to change back using the Group Policy editor (gpedit.msc). Then restarting the machine (again!, as gpupdate /force didn’t cut it either, because SQL had already picked up the value), and finally I could reconnect. On Thursday I simply borrowed another machine for my talk. Today, one of my guys had seen and remembered Dan’s post. Thanks, both of you.
