• Ideal way/architecture to deliver large data over Web Services

  - by zengr

  We are trying to design 6 web services, which will serve another client component. The client component requires data from the web service we are implementing. Now, the problem is, there is not 1 WS we are implementing, there is one WS which the client component hits, this initiates a series (5 more) of WSs which gather data from their respective data stores and finally provide the data back to the original WS, which then delivers the data back to the client component. So, if the requested data becomes huge, then, this will be a serious problem for our internal communication channel. So, what do you guys suggest? What can be done to avoid overloading of the communication channel between the internal WS and at the same time, also delivering the data to the client component.

• Customize iphone app for different clients

  - by gnibbler

  I have an existing app that needs to be compiled for different clients Each client requires their own icon and splash screen. I would also like to be able to conditionally include various features depending whether the particular client requires them or not. I have tried setting up different targets for each client, but not having much luck so far. The different resources with the same name, but a different path keep getting mixed up. Ideally I would like to be able to build an app by duplicating another client that is similar and then just make the minimum number of changes to create the app for the new client. What is the best way to set this app up?

• Can you use POST to run a query in Solr (/select)

  - by RyanFetz

  I have queries that I am running against out solr index that sometimes have very long query parameters, I get errors when i run these queries, which i assume are do to the limit of a GET query parameters. Here is the method I use to query (JSON), this is to show I am using the Http Extensions (the client i use is a thin wrapper for HttpClient) not an end to end solution. 90% of the queries run fine, it is just when the params are large i get the 500 error from solr. I have read somewhere you can use POSt's when doing the select command but have not found examples of how to do it. Any help would be fantastic! public string GetJson(HttpQueryString qs) { using (var client = new DAC.US.Web.XmlHttpServiceClient(this.Uri)) { client.Client.DefaultHeaders.Authorization = new Microsoft.Http.Headers.Credential("Basic", DAC.US.Encryption.Hash.WebServiceCredintials); qs.Add("wt", "json"); if (!String.IsNullOrEmpty(this.Version)) qs.Add("version", this.Version); using (var response = client.Get(new Uri(@"select/", UriKind.Relative), qs)) { return response.Content.ReadAsString(); } } }

• Working with sockets in MFC

  - by fanq

  I'm trying to make a MFC application(client) that connects to a server on ("localhost",port 1234), the server replies to the client and the client reads from the server's response. The server is able to receive the data from the client and it sends the reply back to the socket from where it received it, but I am unable to read the reply from within the client. I am making a CAsyncSocket to connect to the server and send data and a CAsyncSocket with overloaded methods onAccet and onReceive to read the reply from the server. Please tell me what I'm doing wrong.

• Check for new mails in Hotmail using OpenPop.NET

  - by deadlock

  I was advised to use OpenPop lib to fetch my mail from hotmail. But I could'nt find any better way to check for new mail except disconnecting and reconnecting again. And there, I found a problem, Hotmail doesn't allow more than 1 pop3 login each 15 minutes. I want to know if it's possible to get the new mail without disconnecting and reconnecting to their pop3 server. Here is my code: Timer checker = new Timer(); checker.Interval = 1000; checker.Tick += new EventHandler(delegate { Pop3Client client = new Pop3Client(); client.Connect("pop3.live.com", 995, true); client.Authenticate("[email protected]", "myPassword"); label1.Text = client.GetMessageCount().ToString(); client.Disconnect(); }); checker.Start();

• Game network physics collision

  - by Jonas Byström

  How to simulating two client-controlled vehicles colliding (sensibly) in a typical client/server setup for a network game? I did read this eminent blog post on how to do distributed network physics in general (without traditional client prediction), but this question is specifically on how to handle collisions of owned objects. Example Say client A is 20 ms ahead of server, client B 300 ms ahead of server (counting both latency and maximum jitter). This means that when the two vehicles collide, both clients will see the other as 320 ms behind - in the opposite direction of the velocity of the other vehicle. Head-to-head on a Swedish highway means a difference of 16 meters/17.5 yards! What not to try It is virtually impossible to extrapolate the positions, since I also have very complex vehicles with joints and bodies all over, which in turn have linear and angular positions, velocities and accelerations, not to mention states from user input.

• How can i do something like IList<T>.Contains(OtherObjectType) ?

  - by Noctris

  Hi, I have the following classes: Client ClientCacheMedia ( contains Client, Media and some other parameters so it is the link between the media and the client) Media where client contains an IList. Now what i would like to do, is have a way to check if this ilist contains a certain media so : Client.ClientCacheMedia.Contains(MyMedia) is there any way to let the IList accept media as an object to match ? ( i can easily override the Equals Property on ClientCacheMedia to check if the media passed is the one that the ClientCacheMedia.Media contains, it's just the Ilist that will not accept any other object on the Contains Method.

• IPsec tunnel to Android device not created even though there is an IKE SA

  - by Quentin Swain

  I'm trying to configure a VPN tunnel between an Android device running 4.1 and a Fedora 17 Linux box running strongSwan 5.0. The device reports that it is connected and strongSwan statusall returns that there is an IKE SA, but doesn't display a tunnel. I used the instructions for iOS in the wiki to generate certificates and configure strongSwan. Since Android uses a modified version of racoon this should work and since the connection is partly established I think I am on the right track. I don't see any errors about not being able to create the tunnel. This is the configuration for the strongSwan connection conn android2 keyexchange=ikev1 authby=xauthrsasig xauth=server left=96.244.142.28 leftsubnet=0.0.0.0/0 leftfirewall=yes leftcert=serverCert.pem right=%any rightsubnet=10.0.0.0/24 rightsourceip=10.0.0.2 rightcert=clientCert.pem ike=aes256-sha1-modp1024 auto=add This is the output of strongswan statusall Status of IKE charon daemon (strongSwan 5.0.0, Linux 3.3.4-5.fc17.x86_64, x86_64): uptime: 20 minutes, since Oct 31 10:27:31 2012 malloc: sbrk 270336, mmap 0, used 198144, free 72192 worker threads: 8 of 16 idle, 7/1/0/0 working, job queue: 0/0/0/0, scheduled: 7 loaded plugins: charon aes des sha1 sha2 md5 random nonce x509 revocation constraints pubkey pkcs1 pkcs8 pgp dnskey pem openssl fips-prf gmp xcbc cmac hmac attr kernel-netlink resolve socket-default stroke updown xauth-generic Virtual IP pools (size/online/offline): android-hybrid: 1/0/0 android2: 1/1/0 Listening IP addresses: 96.244.142.28 Connections: android-hybrid: %any...%any IKEv1 android-hybrid: local: [C=CH, O=strongSwan, CN=vpn.strongswan.org] uses public key authentication android-hybrid: cert: "C=CH, O=strongSwan, CN=vpn.strongswan.org" android-hybrid: remote: [%any] uses XAuth authentication: any android-hybrid: child: dynamic === dynamic TUNNEL android2: 96.244.142.28...%any IKEv1 android2: local: [C=CH, O=strongSwan, CN=vpn.strongswan.org] uses public key authentication android2: cert: "C=CH, O=strongSwan, CN=vpn.strongswan.org" android2: remote: [C=CH, O=strongSwan, CN=client] uses public key authentication android2: cert: "C=CH, O=strongSwan, CN=client" android2: remote: [%any] uses XAuth authentication: any android2: child: 0.0.0.0/0 === 10.0.0.0/24 TUNNEL Security Associations (1 up, 0 connecting): android2[3]: ESTABLISHED 10 seconds ago, 96.244.142.28[C=CH, O=strongSwan, CN=vpn.strongswan.org]...208.54.35.241[C=CH, O=strongSwan, CN=client] android2[3]: Remote XAuth identity: android android2[3]: IKEv1 SPIs: 4151e371ad46b20d_i 59a56390d74792d2_r*, public key reauthentication in 56 minutes android2[3]: IKE proposal: AES_CBC_256/HMAC_SHA1_96/PRF_HMAC_SHA1/MODP_1024 The output of ip -s xfrm policy src ::/0 dst ::/0 uid 0 socket in action allow index 3851 priority 0 ptype main share any flag (0x00000000) lifetime config: limit: soft 0(bytes), hard 0(bytes) limit: soft 0(packets), hard 0(packets) expire add: soft 0(sec), hard 0(sec) expire use: soft 0(sec), hard 0(sec) lifetime current: 0(bytes), 0(packets) add 2012-10-31 13:29:08 use -

• The Microsoft Ajax Library and Visual Studio Beta 2

  - by Stephen Walther

  Visual Studio 2010 Beta 2 was released this week and one of the first things that I hope you notice is that it no longer contains the latest version of ASP.NET AJAX. What happened? Where did AJAX go? Just like Sting and The Police, just like Phil Collins and Genesis, just like Greg Page and the Wiggles, AJAX has gone out of band! We are starting a solo career. A Name Change First things first. In previous releases, our Ajax framework was named ASP.NET AJAX. We now have changed the name of the framework to the Microsoft Ajax Library. There are two reasons behind this name change. First, the members of the Ajax team got tired of explaining to everyone that our Ajax framework is not tied to the server-side ASP.NET framework. You can use the Microsoft Ajax Library with ASP.NET Web Forms, ASP.NET MVC, PHP, Ruby on RAILS, and even pure HTML applications. Our framework can be used as a client-only framework and having the word ASP.NET in our name was confusing people. Second, it was time to start spelling the word Ajax like everyone else. Notice that the name is the Microsoft Ajax Library and not the Microsoft AJAX library. Originally, Microsoft used upper case AJAX because AJAX originally was an acronym for Asynchronous JavaScript and XML. And, according to Strunk and Wagnell, acronyms should be all uppercase. However, Ajax is one of those words that have migrated from acronym status to “just a word” status. So whenever you hear one of your co-workers talk about ASP.NET AJAX, gently correct your co-worker and say “It is now called the Microsoft Ajax Library.” Why OOB? But why move out-of-band (OOB)? The short answer is that we have had approximately 6 preview releases of the Microsoft Ajax Library over the last year. That’s a lot. We pride ourselves on being agile. Client-side technology evolves quickly. We want to be able to get a preview version of the Microsoft Ajax Library out to our customers, get feedback, and make changes to the library quickly. Shipping the Microsoft Ajax Library out-of-band keeps us agile and enables us to continue to ship new versions of the library even after ASP.NET 4 ships. Showing Love for JavaScript Developers One area in which we have received a lot of feedback is around making the Microsoft Ajax Library easier to use for developers who are comfortable with JavaScript. We also wanted to make it easy for jQuery developers to take advantage of the innovative features of the Microsoft Ajax Library. To achieve these goals, we’ve added the following features to the Microsoft Ajax Library (these features are included in the latest preview release that you can download right now): A simplified imperative syntax – We wanted to make it brain-dead simple to create client-side Ajax controls when writing JavaScript. A client script loader – We wanted the Microsoft Ajax Library to load all of the scripts required by a component or control automatically. jQuery integration – We love the jQuery selector syntax. We wanted to make it easy for jQuery developers to use the Microsoft Ajax Library without changing their programming style. If you are interested in learning about these new features of the Microsoft Ajax Library, I recommend that you read the following blog post by Scott Guthrie: http://weblogs.asp.net/scottgu/archive/2009/10/15/announcing-microsoft-ajax-library-preview-6-and-the-microsoft-ajax-minifier.aspx Downloading the Latest Version of the Microsoft Ajax Library Currently, the best place to download the latest version of the Microsoft Ajax Library is directly from the ASP.NET CodePlex project: http://aspnet.codeplex.com/ As I write this, the current version is Preview 6. The next version is coming out at the PDC. Summary I’m really excited about the future of the Microsoft Ajax Library. Moving outside of the ASP.NET framework provides us the flexibility to remain agile and continue to innovate aggressively. The latest preview release of the Microsoft Ajax Library includes several major new features including a client script loader, jQuery integration, and a simplified client control creation syntax.

• Organizational characteristics that impact the selection of Development Methodology concepts applied to a project

  Based on my experience, no one really follows a specific methodology exactly as it is formally designed. In fact, the key concepts of a few methodologies are usually combined to form a hybrid methodology for each project based on the current organizational makeup and the project need/requirements to be accomplished. Organizational characteristics that impact the selection of methodology concepts applied to a project. Prior subject knowledge pertaining to a project can be critical when deciding on what methodology or combination of methodologies to apply to a project. For example, if a project is very straight forward, and the development staff has experience in developing  that are similar, then the waterfall method could possibly be the best choice because little to no research is needed  in order to complete the project tasks and there is very little need for changes to occur.  On the other hand, if the development staff has limited subject knowledge or the requirements/specification of the project could possibly change as the project progresses then the use of spiral, iterative, incremental, agile, or any combination would be preferred. The previous methodologies used by an organization typically do not change much from project to project unless the needs of a project dictate differently. For example, if the waterfall method is the preferred development methodology then most projects will be developed by the waterfall method. Depending on the time allotted to a project each day can impact the selection of a development methodology. In one example, if the staff can only devote a few hours a day to a project then the incremental methodology might be ideal because modules can be added to the final project as they are developed. On the other hand, if daily time allocation is not an issue, then a multitude of methodologies could work well for a project. Project characteristics that impact the selection of methodology concepts applied to a project. The type of project being developed can often dictate the type of methodology used for the project. Based on my experience, projects that tend to have a lot of user interaction, follow a more iterative, incremental, or agile approach typically using a prototype that develops into a final project. These methodologies desire back and forth communication between users, clients, and developers to allow for requirements to change and functionality to be enhanced. Conversely, limited interaction applications or automated services can still sometimes get away with using the waterfall or transactional approach. The timeline of a project can also force an organization to prefer a particular methodology over the rest. For instance, if the project must be completed within 24 hours, then there is very little time for discussions back and forth between clients, users and the development team. In this scenario, the waterfall method would be perfect because the only interaction with the client occurs prior to a development project to outline the system requirements, and the development team can quickly move through the software development stages in order to complete the project within the deadline. If the team had more time, then the other methodologies could also be considered because there is more time for client and users to review the project and make changes as they see fit, and/or allow for more time to review the project in order to enhance the business performance and functionality. Sometimes the client and or user involvement can dictate the selection of methodologies applied to a project. One example of this is if a client is highly motivated to get a project completed and desires to play an active part in the development process then the agile development approach would work perfectly with this client because it allows for frequent interaction between clients, users and the development team. The inverse of this situation is a client that just wants to provide the project requirements and only wants to get involved when the project is to be delivered. In this case the waterfall method would work well because there is no room for changes and no back and forth between the users, clients or the development team.

• Five geeky things you must do with your Android Smartphone

  - by Gopinath

  Android is the Windows of next generation. Its open, free, widely adopted and smart enough to outsmart Apple’s iOS. It’s a stolen product and cheap imitation of iOS, but Steve Job’s once quoted saying good artists copy and great artists steal. Alright, this post is not about Android vs iOS or is it really stolen or not. Android is a great OS for mobile devices and it lets you do amazing through mobiles.  In this post I want to write about the geeky things we can do with an Android Smartphone. Control your computer using mobile Assume that it is a lazy weekend and you are on a couch watching movies on a laptop which is a meter away. Now you want to adjust volume or skip a scene/song. How to control your laptop without moving out of couch? Just install Universal Remote free app on your smartphone and start control your computer using phone. Universal Remove app controls computers over Wifi or Bluetooth networks with dedicated remote controls for various media players and applications like YouTube, VLC & Spotify.  The application is very easy to use and works amazingly well in controlling computers.

• How to Create SharePoint List and Insert List Item programmatically from a Windows Forms Application.

  - by Michael M. Bangoy

  In this post I’m going to demonstrate how to create SharePoint List and also Insert Items on the List from a Windows Forms Application. 1. Open Visual Studio and create a new project. On the project template select Windows Form Application under C#. 2. In order to communicate with Sharepoint from a Windows Forms Application we need to add the 2 Sharepoint Client DLL located in c:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\ISAPI.  3. Select the Microsoft.Sharepoint.Client.dll and Microsoft.Sharepoint.Client.Runtime.dll. (Your solution should look like the one below) 4. Open the Form1 in design view and from the Toolbox menu add a button on the form surface. Your form should look like the one below. 5. Double click the button to open the code view. Add Using statement to reference the Sharepoint Client Library then create method for the Create List. Your code should like the codes below. using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Security; using System.Windows.Forms; using SP = Microsoft.SharePoint.Client; namespace ClientObjectModel {     public partial class Form1 : Form     {         // url of the Sharepoint site         const string _context = "urlofthesharepointsite";         public Form1()         {             InitializeComponent();         }         private void Form1_Load(object sender, EventArgs e)         {                    }         private void cmdcreate_Click(object sender, EventArgs e)         {             try             {                 // declare the ClientContext Object                 SP.ClientContext _clientcontext = new SP.ClientContext(_context);                 SP.Web _site = _clientcontext.Web;                 // declare a ListCreationInfo                 SP.ListCreationInformation _listcreationinfo = new SP.ListCreationInformation();                 // set the Title and the Template of the List to be created                 _listcreationinfo.Title = "NewListFromCOM";                 _listcreationinfo.TemplateType = (int)SP.ListTemplateType.GenericList;                 // Call the add method to the ListCreatedInfo                 SP.List _list = _site.Lists.Add(_listcreationinfo);                 // Add Description field to the List                 SP.Field _Description = _list.Fields.AddFieldAsXml(@"                                     <Field Type='Text'                                         DisplayName='Description'>                                     </Field>", true, SP.AddFieldOptions.AddToDefaultContentType);                 // declare the List item Creation object for creating List Item                 SP.ListItemCreationInformation _itemcreationinfo = new SP.ListItemCreationInformation();                 // call the additem method of the list to insert a new List Item                 SP.ListItem _item = _list.AddItem(_itemcreationinfo);                 _item["Title"] = "New Item from Client Object Model";                 _item["Description"] = "This item was added by a Windows Forms Application";                 // call the update method                 _item.Update();                 // execute the query of the clientcontext                 _clientcontext.ExecuteQuery();                 // dispose the clientcontext                 _clientcontext.Dispose();                 MessageBox.Show("List Creation Successfull");             }             catch(Exception ex)             {                 MessageBox.Show("Error creating list" + ex.ToString());             }          }     } } 6. Hit F5 to run the application. A message will be displayed on the screen if the operation is successful and also if it fails. 7. To make that the operation of our Windows Form Application has really created the List and Inserted an item on it. Let’s open our SharePoint site. Once the SharePoint is open click on the Site Actions then View All Site Content. 7. Click the List to open it and check if an Item is inserted. That’s it. Hope this helps.

• Design pattern for logging changes in parent/child objects saved to database

  - by andrew

  I’ve got a 2 database tables in parent/child relationship as one-many. I’ve got three classes representing the data in these two tables: Parent Class { Public int ID {get; set;} .. other properties } Child Class { Public int ID {get;set;} Public int ParentID {get; set;} .. other properties } TogetherClass { Public Parent Parent; Public List<Child> ChildList; } Lastly I’ve got a client and server application – I’m in control of both ends so can make changes to both programs as I need to. Client makes a request for ParentID and receives a Together Class for the matching parent, and all of the child records. The client app may make changes to the children – add new children, remove or modify existing ones. Client app then sends the Together Class back to the server app. Server app needs to update the parent and child records in the database. In addition I would like to be able to log the changes – I’m doing this by having 2 separate tables one for Parent, one for child; each containing the same columns as the original plus date time modified, by whom and a list of the changes. I’m unsure as to the best approach to detect the changes in records – new records, records to be deleted, records with no fields changed, records with some fields changed. I figure I need to read the parent & children records and compare those to the ones in the Together Class. Strategy A: If Together class’s child record has an ID of say 0, that indicates a new record; insert. Any deleted child records are no longer in the Together Class; see if any of the comparison child records are not found in the Together class and delete if not found (Compare using ID). Check each child record for changes and if changed log. Strategy B: Make a new Updated TogetherClass UpdatedClass { Public Parent Parent {get; set} Public List<Child> ListNewChild {get;set;} Public List<Child> DeletedChild {get;set;} Public List<Child> ExistingChild {get;set;} // used for no changes and modified rows } And then process as per the list. The reason why I’m asking for ideas is that both of these solutions don’t seem optimal to me and I suspect this problem has been solved already – some kind of design pattern ? I am aware of one potential problem in this general approach – that where Client App A requests a record; App B requests same record; A then saves changes; B then saves changes which may overwrite changes A made. This is a separate locking issue which I’ll raise a separate question for if I’ve got trouble implementing. The actual implementation is c#, SQL Server and WCF between client and server - sharing a library containing the class implementations. Apologies if this is a duplicate post – I tried searching various terms without finding a match though.

• The Power to Control Power

  - by speakjava

  I'm currently working on a number of projects using embedded Java on the Raspberry Pi and Beagle Board.  These are nice and small, so don't take up much room on my desk as you can see in this picture. As you can also see I have power and network connections emerging from under my desk.  One of the (admittedly very minor) drawbacks of these systems is that they have no on/off switch.  Instead you insert or remove the power connector (USB for the RasPi, a barrel connector for the Beagle).  For the Beagle Board this can potentially be an issue; with the micro-SD card located right next to the connector it has been known for people to eject the card when trying to power off the board, which can be quite serious for the hardware. The alternative is obviously to leave the boards plugged in and then disconnect the power from the outlet.  Simple enough, but a picture of underneath my desk shows that this is not the ideal situation either. This made me think that it would be great if I could have some way of controlling a mains voltage outlet using a remote switch or, even better, from software via a USB connector.  A search revealed not much that fit my requirements, and anything that was close seemed very expensive.  Obviously the only way to solve this was to build my own.Here's my solution.  I decided my system would support both control mechanisms (remote physical switch and USB computer control) and be modular in its design for optimum flexibility.  I did a bit of searching and found a company in Hong Kong that were offering solid state relays for 99p plus shipping (£2.99, but still made the total price very reasonable).  These would handle up to 380V AC on the output side so more than capable of coping with the UK 240V supply.  The other great thing was that being solid state, the input would work with a range of 3-32V and required a very low current of 7.5mA at 12V.  For the USB control an Arduino board seemed the obvious low-cost and simple choice.  Given the current requirments of the relay, the Arduino would not require the additional power supply and could be powered just from the USB.Having secured the relays I popped down to Homebase for a couple of 13A sockets, RS for a box and an Arduino and Maplin for a toggle switch.  The circuit is pretty straightforward, as shown in the diagram (only one output is shown to make it as simple as possible).  Originally I used a 2 pole toggle switch to select the remote switch or USB control by switching the negative connections of the low voltage side.  Unfortunately, the resistance between the digital pins of the Arduino board was not high enough, so when using one of the remote switches it would turn on both of the outlets.  I changed to a 4 pole switch and isolated both positive and negative connections. IMPORTANT NOTE: If you want to follow my design, please be aware that it requires working with mains voltages.  If you are at all concerned with your ability to do this please consult a qualified electrician to help you.It was a tight fit, especially getting the Arduino in, but in the end it all worked.  The completed box is shown in the photos. The remote switch was pretty simple just requiring the squeezing of two rocker switches and a 9V battery into the small RS supplied box.  I repurposed a standard stereo cable with phono plugs to connect the switch box to the mains outlets.  I chopped off one set of plugs and wired it to the rocker switches.  The photo shows the RasPi and the Beagle board now controllable from the switch box on the desk. I've tested the Arduino side of things and this works fine.  Next I need to write some software to provide an interface for control of the outlets.  I'm thinking a JavaFX GUI would be in keeping with the total overkill style of this project.

• Trying to configure HWIC-3G-HSPA

  - by user1174838

  I'm trying to configure a couple of Cisco 1941 routes. The are both identical routers. Each as a HWIC-1T (Smart Serial interface) and a HWIC-3G-HSPA 3G interface. These routers are to be sent to remote sites. We have connectivity to one of the sites but if remote site A gors down we lose connectivity to remote site B. The HWIC-1T is the primary WAN interface using frame relay joining the two remote sites We want the HWIC-3G-HSPA to be usable for direct connectivity from head office to remote site B, and also the HWIC-3G-HSPA is do be used for comms between the remote sites when the frame relay is down (happens quite a bit). I initialy tried to do dynamic routing using EIGRP however in my lab setup of laptop - 1941 - 1941 - laptop, I was unable to get end to end connectivity. I later settled on static routing and have got end to end connectivity but only over frame relay, not the HWIC-3G-HSPA.

• Friday Tips #6, Part 1

  - by Chris Kawalek

  We have a two parter this week, with this post focusing on desktop virtualization and the next one on server virtualization. Question: Why would I use the Oracle Secure Global Desktop Secure Gateway? Answer by Rick Butland, Principal Sales Consultant, Oracle Desktop Virtualization: Well, for the benefit of those who might not be familiar with client connections in Oracle Secure Global Desktop (SGD), let me back up and briefly explain. An SGD client connects to an SGD server using two distinct protocols, which, by default, require two distinct TCP ports. The first is the HTTP protocol, used by the web browser to connect to the SGD webserver on TCP port 80, or if secure connections are enabled (SSL/TLS), then TCP port 443, commonly identified as the "HTTPS" port, that is, "SSL encrypted HTTP." The second protocol from the client to the server is the Adaptive Internet Protocol, or AIP, which is used for displaying applications, transferring drive mapping data, print jobs, and so on. By default, AIP uses the TCP port 3104, or port 5307 when SSL is enabled. When SGD clients need to access SGD over a firewall, the ports that AIP requires are typically "closed"; and most administrators are reluctant, to put it mildly, to change their firewall configurations to allow AIP traffic on 3144/5307.   To avoid this problem, SGD introduced "Firewall Forwarding", a technique where, in effect, both http and AIP traffic are "multiplexed" onto a single "well-known" TCP port, that is port 443, the https port.  This is also known as single-port firewall traversal.  This technique takes advantage of the fact that, as a "well-known service", port 443 is usually "open",   allowing (encrypted) traffic to pass. At the target SGD server, the two protocols are de-multiplexed and routed appropriately. The Secure Gateway was developed in response to requirements from customers for SGD to support multi-stage DMZ's, and to avoid exposing SGD servers and the information they contain directly to connections from the Internet. The Secure Gateway acts as a reverse-proxy in the first-tier of the DMZ, accepting, authenticating, and terminating incoming client connections, and then re-encrypting the connections, and proxying them, routing them on to SGD servers, deeper in the network. The client no longer needs to know the name/IP address of the SGD servers in their network, they connect to the gateway, only. The gateway takes care of those internal network details.     The Secure Gateway supports the same "single-port firewall" capability as does "Firewall Forwarding", but offers the additional advantage of load-balancing incoming client connections amongst SGD array members, which could be cumbersome without a forward-deployed secure gateway. Load-balancing weights and policies can be monitored and tuned using the "Balancer Manager" application, and Apache mod_proxy_balancer directives.   Going forward, our architects recommend the use of the Secure Gateway over "Firewall Forwarding" for single-port firewall traversal, due to its architectural advantages, its greater flexibility and enhanced features.  Finally, it should be noted that the Secure Gateway is not separately priced; any licensed SGD customer may use the Secure Gateway component at no additional cost.   For more information, see the "Secure Gateway Administrator's Guide".

• Introduction to WebCenter Personalization: &ldquo;The Conductor&rdquo;

  - by Steve Pepper

  There are some new faces in the town of WebCenter with the latest 11g PS3 release.  A new component has introduced itself as "Oracle WebCenter Personalization", a.k.a WCP, to simplify delivery of a personalized experience and content to end users.  This posting reviews one of the primary components within WCP: "The Conductor". The Conductor: This ain't just an ordinary cloud... One of the founding principals behind WebCenter Personalization was to provide an open client-side API that remains independent of the technology invoking it, in addition to independence from the architecture running it.  The Conductor delivers this, and much, much more. The Conductor is the engine behind WebCenter Personalization that allows flow-based documents, called "Scenarios", to be managed and executed on the server-side through a well published and RESTful api.      The Conductor also supports an extensible model for custom provider integration that can be easily invoked within a Scenario to promote seamless integration with existing business assets. Introducing the Scenario Conductor Scenarios are declarative offline-authored documents using the custom Personalization JDeveloper bundle included with WebCenter.  A Scenario contains one (or more) statements that can: Create variables that are scoped to the current execution context Iterate over collections, or loop until a specific condition is met Execute one or more statements when a condition is met Invoke other scenarios that exist within the same namespace Invoke a data provider that integrates with custom applications Once a variable is assigned within the Scenario's execution context, it can be referenced anywhere within the same Scenario using the common Expression Language syntax used in J2EE web containers. Scenarios are then published and tested to the Integrated WebLogic Server domain, or published remotely to other domains running WebCenter Personalization. Various Client-side Models The Conductor server API is built upon RESTful services that support a wide variety of clients able to communicate over HTTP.  The Conductor supports the following client-side models: REST:  Popular browser-based languages can be used to manage and execute Conductor Scenarios.  There are other public methods to retrieve configured provider metadata that can be used by custom applications. The Conductor currently supports XML and JSON for it's API syntax. Java: WebCenter Personalization delivers a robust and light-weight java client with the popular Jersey framework as it's foundation.  It has never been easier to write a remote java client to manage remote RESTful services. Expression Language (EL): Allow the results of Scenario execution to control your user interface or embed personalized content using the session-scoped managed bean.  The EL client can also be used in straight JSP pages with minimal configuration. Extensible Provider Framework The Conductor supports a pluggable provider framework for integrating custom code with Scenario execution.  There are two types of providers supported by the Conductor: Function Provider: Function Providers are simple java annotated classes with static methods that are meant to be served as utilities.  Some common uses would include: object creation or instantiation, data transformation, and the like.  Function Providers can be invoked using the common EL syntax from variable assignments, conditions, and loops. For example:  ${myUtilityClass:doStuff(arg1,arg2))} If you are familiar with EL Functions, Function Providers are based on the same concept. Data Provider: Like Function Providers, Data Providers are annotated java classes, but they must adhere to a much more strict object model.  Data Providers have access to a wealth of Conductor services, such as: Access to namespace-scoped configuration API that can be managed by Oracle Enterprise Manager, Scenario execution context for expression resolution, and more.  Oracle ships with three out-of-the-box data providers that supports integration with: Standardized Content Servers(CMIS),  Federated Profile Properties through the Properties Service, and WebCenter Activity Graph. Useful References If you are looking to immediately get started writing your own application using WebCenter Personalization Services, you will find the following references helpful in getting you on your way: Personalizing WebCenter Applications Authoring Personalized Scenarios in JDeveloper Using Personalization APIs Externally Implementing and Calling Function Providers Implementing and Calling Data Providers

• How can I work efficiently on a desktop sharing workflow?

  - by OSdave

  I am a freelance Magento developer, based in Spain. One of my clients is a Germany based web development company and they're asking me something I think it's impossible. OK, maybe not impossible but definitely not a preferred way of doing things. One of their clients has a Magento Entreprise installation, which is the paid (and I think proprietary) version of Magento. Their client has forbidden them to download the files from his server. My client is asking me now to study one particular module of the application in order to interact with it from a custom module I'll have to develop. As they have a read-only ssh access to their client's server, they came up with this solution: Set up a desktop/screen sharing session between one of their developer's station and mine, alongsides with a skype conversation. Their idea is that I'll say to the developer: show me file foo.php The developer will then open this foo.php file in his IDE. I'll have then to ask him to show me the bar method, the parent class, etc... Remember that it's a read-only session, so forget about putting a Zend_Debug::log() anywhere, and don't even think about a xDebug breakpoint (they don't use any kind of debugger, sic). Their client has also forbidden them to use any version control system... My first reaction when they explained to me this was (and I actually did say it outloud to them): Well, find another client. but they took it as a joke from me. I understand that in a business point of view rejecting a client is not a good practice, but I think that the condition of this assignment make it impossible to complete. At least according to my workflow. I mean, the way I work or learn a new framework/program is: download all files and copy of db on my pc create a git repository and a branch run the application locally use breakpoints use Zend_Debug::log() write the code and tests commit to git repo upload to (test/staging first if there is one, production if not) server I have agreed to try the desktop sharing session, although I think it will be a waste of time. On one hand I don't mind, they pay me for that time, but I know me and I don't like the sensation of loosing my time. On the other hand, I have other clients for whom I can work according to my workflow. I am about to say to them that I cannot (don't want to) do it. Well, I'll first try this desktop sharing session: maybe I'm wrong and it can actually work. But I like to consider myself as a professional, and I know that I don't know everything. So I try to keep an open mind and I am always willing to learn new stuff. So my questions are: Can this desktop-sharing workflow work? What should be done in order to take the most of it? Taking into account all the obstacles (geographic locations, no local, no git), is there another way for me to work on that project?

• Nagios plugin script not working as expected

  - by Linker3000

  I have modified an off-the-shelf Nagios plugin perl script to (in theory) return a one or zero according to the existence, or not, of a file on a remote linux server. The script runs a remote ssh session and logs in as the nagios user. The remote linux servers have private keys setup for that user, and on the bash command line the script works as expected, but when run as a plugin it always returns '1' (true) even if the file does not exist. Some help with the logic or a comment on why things are not working as expected within Nagios would be appreciated. I'd prefer to use this ssh login method rather than having to install nrpe on all the linux servers. To run from a command line (assuming remote server has a user called nagios with a valid private key): ./check_reboot_required -e ssh -H remote-servers-ip-addr -p 'filename-to-check' -v Ta. #! /usr/bin/perl -w # # # License Information: # This program is free software; you can redistribute it and/or modify # it under the terms of the GNU General Public License as published by # the Free Software Foundation; either version 2 of the License, or # (at your option) any later version. # # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

• How can I get TFS2010 to run MSDEPLOY for me through MSBUILD?

  - by Simon_Weaver

  There is an excellent PDC talk available here which describes the new MSDEPLOY features in Visual Studio 2010 - as well as how to deploy an application within TFS. You can use MSBUILD within TFS2010 to call through to MSDEPLOY to deploy your package to IIS. This is done by means of parameters to MSBUILD. The talk explains some of the command line parameters such as : /p:DeployOnBuild /p:DeployTarget=MsDeployPublish /p:CreatePackageOnPublish=True /p:MSDeployPublishMethod=InProc /p:MSDeployServiceURL=localhost /p:DeployIISAppPath="Default Web Site" But where is the documentation for this - I can't find any? I've been spending all day trying to get this to work and can't quite get it right and keep ending up with various errors. If I run the package's cmd file it deploys perfectly. But I want to get the whole deployment running through msbuild using these arguments and not a separate call to msdeploy or running the package .cmd file. How can I do this? PS. Yes I do have the Web Deployment Agent Service running. I also have the management service running under IIS. I've tried using both. Args I'm using : /p:DeployOnBuild=True /p:DeployTarget=MsDeployPublish /p:Configuration=Release /p:CreatePackageOnPublish=True /p:DeployIisAppPath=staging.example.com /p:MsDeployServiceUrl=https://staging.example.com:8172/msdeploy.axd /p:AllowUntrustedCertificate=True giving me : C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v10.0\Web\Microsoft.Web.Publishing.targets (2660): VsMsdeploy failed.(Remote agent (URL https://staging.example.com:8172/msdeploy.axd?site=staging.example.com) could not be contacted. Make sure the remote agent service is installed and started on the target computer.) Error detail: Remote agent (URL https://staging.example.com:8172/msdeploy.axd?site=staging.example.com) could not be contacted. Make sure the remote agent service is installed and started on the target computer. An unsupported response was received. The response header 'MSDeploy.Response' was '' but 'v1' was expected. The remote server returned an error: (401) Unauthorized.

• C# Ignore certificate errors?

  - by JL

  I am getting the following error during a web service request to a remote web service: Could not establish trust relationship for the SSL/TLS secure channel. --- System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to the validation procedure. Is there anyway to ignore this error, and continue. It seems the remote certificate is not signed. The site I connect to is www.czebox.cz - so feel free to visit the site, and notice even browsers through security exceptions. Thanks

• How to build google breakpad

  - by Steve

  Hi, I'm totally lost on how to build Google's breakpad. There is a sln file, but it depends on a library that doesn't seem to have an associated sln. It seems to use something called gyp that I haven't figured out how to get working. I tried python gyp ..\breakpad\src\client\windows\breakpad_client.gyp and that just gives the following errors Traceback (most recent call last): File "gyp", line 18, in <module> sys.exit(gyp.main(sys.argv[1:])) File "pylib\gyp\__init__.py", line 445, in main options.circular_check) File "pylib\gyp\__init__.py", line 84, in Load depth, generator_input_info, check, circular_check) File "pylib\gyp\input.py", line 2165, in Load VerifyNoGYPFileCircularDependencies(targets) File "pylib\gyp\input.py", line 1429, in VerifyNoGYPFileCircularDependencies ' '.join(bad_files) gyp.input.CircularException: Some files not reachable, cycle in .gyp file dependency graph detected involving some or all of: ..\breakpad\src\client\windows\sender\crash_report_sender.gyp ..\breakpad\src\client\windows\h andler\exception_handler.gyp ..\breakpad\src\client\windows\breakpad_client.gyp ..\breakpad\src\client\windows\unittests\client_tests.gyp ..\breakpad\src\client\windows\crash_generation\crash_generation.gyp Which I can't make any sense out of. I also can't seem to find any documentation. Any help would be appreciated.

• Visual Studio 2010 Web Deployment

  - by Cranialsurge

  I am trying to use VS2010's 1-Click Publish feature to deploy a test site from my laptop to my server. I have the firewall turned off on both machines and the MS Deployment Service is up and running on both my laptop and the server. However when I try and publish from VS2010 on my laptop I get the following error Error 1 Web deployment task failed.(Remote agent (URL https://192.168.1.181/:8172/msdeploy.axd?site=LocationsTest) could not be contacted. Make sure the remote agent service is installed and started on the target computer.) The requested resource does not exist, or the requested URL is incorrect. Error details: Remote agent (URL https://192.168.1.181/:8172/msdeploy.axd?site=LocationsTest) could not be contacted.

The remote server returned an error: (404) Not Found. 0 0 Test.Web Any idea what I am doing wrong here ?

• Silverlight and Encryption, how to store/generate they key/iv pair?

  - by cmaduro

  I have a Silverlight app that connects to a php webservice. I want to encrypt the communication between the webservice and the Silverlight client. I'm not relying on SSL. I'm encrypting/decrypting the POST string myself using AES 256bit Key and IV. The big questions then are: How do I generate a random unique key/iv pair in PHP. How do I share this key/iv pair between the web service and silverlight client in a secure way. It seems impossible without having some kind of hard coded key or iv on the client. Which would compromise security. This is a public website, there are no logins. Just the requirement of secure communication. I can hard code the seed for the key/iv (which is hashed with SHA256 with a time stamp salt and then assigned as the key or iv) in PHP source code, that's on the server so that is pretty safe. However on the client the seed for the key/iv pair would be visible, if it is hard coded. Further more using a time stamp as the basis for uniqueness/randomness is definitely not ok, since timestamps are predictable. It does however provide a common factor between the C# code and the PHP code. The only other option that I can think of would be to have a 3rd service involved that provides the key/iv to the Silverlight client, as well as the php webservice. This of course start the cycle anew, with the question of how to store the credentials for accessing the key/iv distribution service on the Silverlight client. Sounds like the solution is then asymmetric encryption, since sensitive data will be viewed only on the administrative back end of the website. Unfortunately Silverlight has no asymmetric encryption classes. The solution? Roll my own Diffie-Hellman key exchange! Plug that key into AES256!
