  • Stream Media and Live TV Across the Internet with Orb

    - by DigitalGeekery
    Looking for a way to stream your media collection across the Internet? Or perhaps watch and record TV remotely? Today we are going to look at how to do all that and more with Orb. Requirements Windows XP / Vista / 7 or Intel based Mac w/ OS X 10.5 or later. 1 GB RAM or more Pentium 4 2.4 GHz or higher / AMD Athlon 3200+ Broadband connections TV Tuner for streaming and recording live TV (optional) Note: Slower internet connections may result in stuttering during playback. Installation and Setup Download and install Orb on your home computer. (Download link below) You’ll want to take the defaults for the initial portion of the install. When we get to the Orb Account setup portion of the install is when we will have to enter information and make some decisions. Choose your language and click Next. We’ll need to create and user account and password. A valid email address is required as we’ll need to confirm the account later. Click Next.   Now you’ll want to choose your media sources. Orb will automatically look for folders that may contain media files. You can add or remove folders click on the (+) or (-) buttons. To remove a folder, click on it once to select it from the list and then click the minus (-) button. To add a folder, click the plus (+) button and browse for the folder. You can add local folders as well as shared folders from networked computers and USB attached storage. Note: Both the host computer running Orb and the networked computer will need to be running to access shared network folders remotely. When you’ve selected all your media files, click Next. Orb will proceed to index your media files… When the indexing is complete, click Next. Orb TV Setup Note: Streaming Live TV to Macs is not currently supported. If you have a TV tuner card connected to your PC, you can opt to configure Orb to stream live or recorded TV. Click Next  to configure TV. Or, choose Skip if you don’t wish to configure Orb for TV.   If you have a Digital tuner card, type in your Zip Code and click Get List to pull your channel listings. Select a TV provider from the list and click Next. If not, click Skip.   You can select or deselect any channels by checking or un-checking the box to each channel. Select Auto Scan to let Orb find more channels or disable the ones with no reception. Click Next when finished.   Next choose an analog provider, if necessary, and click Next.   Select “Yes” or “No” for a set top box and click Next. Just as we did with the Digital tuner, select or deselect any channels by checking or un-checking the box to each channel. Select Auto Scan to let Orb find more channels or disable the ones with no reception. Click Next when finished.   Now we’re finished with the setup. Click Close. Accessing your Media Remotely Media files are accessed through a web-based interface. Before we go any further, however, we’ll need to confirm our username and password. Check your inbox for an email from Orb Networks. Click the enclosed confirmation link. You’ll be prompted to enter the username and password you selected in your browser then click Next.   Your account will be confirmed. Now, we’re ready to enjoy our media remotely. To get started, point your browser to the MyCast website from your remote computer. (See link below) Enter your credentials and click Log In. Once logged in, you’ll be presented with the MyCast Home screen. By default you’ll see a handful of “channels” such as a TV program guide, random audio and photos, video favorites, and weather. You can add, remove, or customize channels. To add additional channels, click on Add Channels at the top right…   …and select from the dropdown list. To access your full media libraries, click Open Application at the top left and select from one of the options. Live and Recorded TV If you have a TV tuner card you configured for Orb, you’ll see your program guide on the TV / Webcams screen. To watch or record a show, click on the program listing to bring up a detail box. Then click the red button to record, or the green button to play. When recording a show, you’ll see a pulsating red icon at the top right of the listing in the program guide. If you want to watch Live TV, you may be prompted to choose your media player, depending on your browser and settings. Playback should begin shortly.   Note for Windows Media Center Users If you try to stream live TV in Orb while Windows Media Center is running on your PC, you’ll get an error message. Click the Stop MediaCenter button and then try again.   Audio On the Audio screen, you’ll find your music files indexed by genre, artist, and album. You can play a selection by clicking once and then clicking the green play button, or by simply double-clicking.   Playback will begin in the default media player for the streaming format.   Video Video works essentially the same as audio. Click on a selection and press the green play button, or double-click on the video title. Video playback will begin in the default media player for the streaming format.   Streaming Formats You can change the default streaming format in the control panel settings. To access the Control Panel, click on Open Applications  and select Control Panel. You can also click Settings at the top right.   Select General from the drop down list and then click on the Streaming Formats tab. You are provided four options. Flash, Windows Media, .SDP, and .PLS.   Creating Playlists To create playlists, drag and drop your media title to the playlist work area on the right, or click Add to playlist on the top menu. Click Save when finished.    Sharing your Media Orb allows you to share media playlists across the Internet with friends and family. There are a few ways to accomplish this. We’ll start by click the Share button at the bottom of the playlist work area after you’ve compiled your playlist. You’ll be prompted to choose a method by which to share your playlist. You’ll have the option to share your playlist publicly or privately. You can share publically through links, blogs, or on your Orb public profile.  By choosing the Public Profile option, Orb will automatically create a profile page for you with a URL like http://public.orb.com/username that anyone can easily access on the Internet. The private sharing option allows you to invite friends by email and requires recipients to register with Orb. You can also give your playlist a custom name, or accept the auto-generated title. Click OK when finished. Users who visit your public profile will be able to view and stream any of your shared playlists to their computer or supported device.   Portable Media Devices and Smartphones Orb can stream media to many portable devices and 3G phones. Streaming audio is supported on the iPhone and iPod Touch through the Safari browser. However, video and live TV streaming requires the Orb Live iPhone App.  Orb Live is available in the App store for $9.99. To stream media to your portable device, go to the MyCast website in your mobile browser and login. Browse for your media or playlist. Make a selection and play the media. Playback will begin. We found streaming music to both the Droid and the iPhone to work quite nicely. Video playback on the Droid, however, left a bit to be desired. The video looked good, but the audio tended to be out of sync. System Tray Control Panel By default Orb runs in the system tray on start up. To access the System Tray Control Panel, right-click on the Orb icon in the system tray and select Control Panel. Login with your Orb username and  password and click OK.   From here you can add or remove media sources, add manage accounts, change your password, and more. If you’d rather not run Orb on Startup, click the General icon.   Unselect the checkbox next to Start Orb when the system starts. Conclusion It may seem like a lot of steps, but getting Orb up and running isn’t terribly difficult. Orb is available for both Windows and Intel based Macs. It also supports streaming to many Game Consoles such as the Wii, PS3, and XBox 360.

  • How to work RavenDB Id with ASP.NET MVC Routes

    - by shiju
    By default RavenDB's Id would be sperated by "/". Let's say that we have a category object, the Ids would be like "categories/1". This will make problems when working with ASP.NET MVC's route rule. For a route category/edit/id, the uri would be category/edit/categories/1. You can solve this problem in two waysSolution 1 - Change Id SeparatorWe can use different Id Separator for RavenDB Ids in order to working with ASP.NET MVC route rules. The following code specify that Ids would be seperated by "-" rather than the default "/"  documentStore = new DocumentStore { Url = "http://localhost:8080/" };  documentStore.Initialize();  documentStore.Conventions.IdentityPartsSeparator = "-"; The above IdentityPartsSeparator would be generate Ids like "categories-1"Solution 2 - Modify ASP.NET MVC Route Modify the ASP.NET MVC routes in the Global.asax.cs file, as shown in the following code  routes.MapRoute(     "WithParam",                                           // Route name     "{controller}/{action}/{*id}"                         // URL with parameters     );  We just put "*" in front of the id variable that will be working with the default Id separator of RavenDB

  • Why is C++ backward compatibility important / necessary?

    - by Giorgio
    As far as understand it is a well-established opinion within the C++ community that C is an obsolete language that was useful 20 years ago but cannot support many modern good programming practices, or even encourages bad practices; certain features that were typical of C++ (C with classes) during the nineties are also obsolete and considered bad practice in modern C++ (e.g., new and delete should be replaced by smart pointer primitives). In view of this, I often wonder why backward compatibility with C and obsolete C++ features is still considered important: to my knowledge there is no 100% compatibility, but most of C and C++ are contained in C++11 as a subset. Of course, there is a lot of legacy code and libraries (possibly containing templates) that are written using a previous standard of the language and which still need to be maintained or used in connection with new code. Nevertheless, maybe it would still be possible to drop obsolete C and C++ features (e.g. the mentioned new / delete) from a future C++ standard so that it is impossible to use them in new code. In this way, old and dangerous programming practices would be quickly banned from new code, and modern, better programming practices would be enforced by the compiler. Legacy code could still be maintained using separate compilation (having C alongside C++ source files is already a common practice). Developers would have to choose between one compiler supporting the old-style C++ that was common during the nineties and a compiler supporting the modern C++? style (the question mark indicates a future, hypothetical revision). Only mixing the two styles would be forbidden. Would this be a viable strategy for encouraging the adoption of modern C++ practices? Are there conceptual reasons or technical problems (e.g. compiling existing templates) that make such a change undesirable or even impossible? Has such a development been proposed in the C++ community. If there has been some extended discussion on the topic, is there any material on-line?

  • Convert a Row to a Column in Excel the Easy Way

    - by Matthew Guay
    Sometimes we’ve entered data in a column in Excel, only to realize later that it would be better to have this data in a row, or vise-versa.  Here’s a simple trick to convert any row or set of rows into a column, or vise-versa, in Excel. Please Note: This is tested in Excel 2003, 2007, and 2010.  Here we took screenshots from Excel 2010 x64, but it works the same on the other versions. Convert a Row to a Column Here’s our data in Excel: We want to change these two columns into rows.  Select all the cells you wish to convert, right-click, and select copy (or simply press Ctrl+C): Now, right-click in the cell where you want to put the data in rows, and select “Paste Special…”   Check the box at the bottom that says “Transpose”, and then click OK. Now your data that was in columns is in rows! This works the exact same for converting rows into columns.  Here’s some data in rows:   After copying and pasting special with Transpose selected, here’s the data in columns! This is a great way to get your data organized just like you want in Excel.

  • Python — Time complexity of built-in functions versus manually-built functions in finite fields

    - by stackuser
    Generally, I'm wondering about the advantages versus disadvantages of using the built-in arithmetic functions versus rolling your own in Python. Specifically, I'm taking in GF(2) finite field polynomials in string format, converting to base 2 values, performing arithmetic, then output back into polynomials as string format. So a small example of this is in multiplication: Rolling my own: def multiply(a,b): bitsa = reversed("{0:b}".format(a)) g = [(b<<i)*int(bit) for i,bit in enumerate(bitsa)] return reduce(lambda x,y: x+y,g) Versus the built-in: def multiply(a,b): # a,b are GF(2) polynomials in binary form .... return a*b #returns product of 2 polynomials in gf2 Currently, operations like multiplicative inverse (with for example 20 bit exponents) take a long time to run in my program as it's using all of Python's built-in mathematical operations like // floor division and % modulus, etc. as opposed to making my own division, remainder, etc. I'm wondering how much of a gain in efficiency and performance I can get by building these manually (as shown above). I realize the gains are dependent on how well the manual versions are built, that's not the question. I'd like to find out 'basically' how much advantage there is over the built-in's. So for instance, if multiplication (as in the example above) is well-suited for base 10 (decimal) arithmetic but has to jump through more hoops to change bases to binary and then even more hoops in operating (so it's lower efficiency), that's what I'm wondering. Like, I'm wondering if it's possible to bring the time down significantly by building them myself in ways that maybe some professionals here have already come across.

  • Allen for Umbraco with location EXIF meta data

    - by Vizioz Limited
    The latest version of Allen for Umbraco has now hit the Apple App store, we have managed to add some nice improvements to this version that include:Storing location and direction information when photos are taken within the AppEmbedding EXIF data into the images when they are uploadBackground UploadingPull to refresh the media tree Location and DirectionBy default when the camera is used within an application the location and direction that the camera is pointing is not stored within the image meta data. We have now added full support so that this data is now added. We have added a setting which allows you to prevent this data from being uploaded to your website if you do not want the location data to be sent you can turn it off within Allen, Note: Please don't forget that location services do need to be turned on to allow the app to access the images in the phone's asset library.We have had quite a few ideas from users already for using this location data, including logging free parking in Denmark to geo-tagging holiday photos and linking the photos to Google street view. Embedding EXIF dataWe now embed all the meta data available on the iPhone into the image when it is uploaded to your server, this allows you to pull the data out and use it within your site. Have a look at Cultiv's Photo Meta Data package for great example code that allows you to automatically pull this data out and populate properties on your Umbraco media item.We slightly modified the source code of this package to allow the package to always extract the image data, as the default package requires a property to allow the data to be extracted, it's an easy change, if you get stuck add a comment to this post. Background UploadingIf you try to upload multiple images and need to start doing something else on your phone, you can now click the home button and the application will continue to upload your images in the background. As soon as it has finished you will receive a standard Apple notification. Pull to RefreshOur final enhancement has been to add "Pull to refresh" to the media trees, just pull the tree downwards with your finger and it will refresh, this is useful if you are adding items to your media tree while testing your site with Allen for Umbraco. Future enhancements.. your ideas?If you have any ideas for future enhancement feel free to add a comment below!

  • Need some advice regarding collision detection with the sprite changing its width and height

    - by Frank Scott
    So I'm messing around with collision detection in my tile-based game and everything works fine and dandy using this method. However, now I am trying to implement sprite sheets so my character can have a walking and jumping animation. For one, I'd like to to be able to have each frame of variable size, I think. I want collision detection to be accurate and during a jumping animation the sprite's height will be shorter (because of the calves meeting the hamstrings). Again, this also works fine at the moment. I can get the character to animate properly each frame and cycle through animations. The problems arise when the width and height of the character change. Often times its position will be corrected by the collision detection system and the character will be rubber-banded to random parts of the map or even go outside the map bounds. For some reason with the linked collision detection algorithm, when the width or height of the sprite is changed on the fly, the entire algorithm breaks down. The solution I found so far is to have a single width and height of the sprite that remains constant, and only adjust the source rectangle for drawing. However, I'm not sure exactly what to set as the sprite's constant bounding box because it varies so much with the different animations. So now I'm not sure what to do. I'm toying with the idea of pixel-perfect collision detection but I'm not sure if it would really be worth it. Does anyone know how Braid does their collision detection? My game is also a 2D sidescroller and I was quite impressed with how it was handled in that game. Thanks for reading.

  • virtualbox, MAAS: help needed

    - by Roberto Attias
    Ok, I made some progress wrt the original question (still below). I found /etc/maas/dhcpd.conf contained option domain-name-servers 10.0.3.15, and changed it to 192.168.0.11. After restarting the daemon, I now see "node" getting the right DNS, unfortunately this doesn't fix the main problem, which I believe is the reference to 169.254.169.254. It does introduce a new question: while the remaining information from /etc/maas/dhcp.conf is present in the maas GUI, there is no field to enter the dns address. Why? Anyway, my original problem still stands... Any idea? Original question follows. In VirtualBox, I have: master VM: ubuntu 12.04.3 server eth0: Internal Network, IP= 192.168.0.11 eth1: NAT, IP= 10.0.3.15 eth2: Host-only, IP= 192.168.56.102 running MAAS region and cluster controlller, with DHCP and DNS enabled node VM: eth0: Internal Network node VM boots in PXEboot. DHCP succeeds, and the boot process starts, but during boot I see some issues. One of them is "disk drive not ready yet or not present" for / and /tmp. I've googled this issue, and some people say it happens when the fisical disk is a SSD, which is my case. Anywaythe system seems to recover from this eventually. Immediately after it starts printing a lot of messages of the form: 2013-10-01 16:52:37,142 - url_helper.py[WARNING]: Calling 'http://169.254.168.254/2009-04-04/meta-data/instance-id failed [x/y]: url error [[Errno 113] No route to host] That IP address is clearly bogous, not sure where it came from. Before that point, I had seen the following network configuration: address: 192.168.0.100 broadcast: 192.168.0.255 netmask: 255.255.255.0 gateway: 192.168.0.1 dns0 : 10.0.3.15 dns1 : 0.0.0.0 Not sure if related, but the dns doesn't seem right, as node doesn't have an interface to reach 10.0.3.15. If that's the problem, what should I change to have the DNS point to 192.168.0.11? Thanks, Roberto

  • Software for "High-level" source code (C++) Management

    - by Korchkidu
    after a lot of small-medium projects, I have a lot of libraries and test programs here and there. Also, I must admit that some of the "best practices" I learnt are not that "good" IMHO. In particular, documenting your code and making a "high-level" documentation is not useful in practice: High-level documentation are not maintain up to date = I prefer to read the source code directly; Browsing generated developer documentation is a pain (IMHO) = I prefer to read the source code directly. For that reason, I am looking for a tool who could help me organize all my source code directories in a more "readable manner". What I need is a tool which: Maintains an UML diagram from C++ source code. I don't need source code generation from UML; USE CASE: I am in this super-tool, I notice a design issue, I change the source code, when I get back, the UML diagram is updated; Maintains easily browsable call graphs; Lists references to methods, variables, etc. For example, when I want to see where/when a method is called; Helps writing pseudo-code from C++; Embeds a nice C++ source code browser; Is Open Source would be great; Works at least on Win7. The focus of this tool should be to browse source code to understand what's going on. For example, when you have a newcomer and you need him to go through source code. Do you know any great tool? Thanks in advance. PS: please do not answer doxygen (great tool however).

  • Entity Framework v1 &hellip; Brief Synopsis and Tips &ndash; Part 2

    - by Rohit Gupta
    Using Entity Framework with ASMX Web sErvices and WCF Web Service: If you use ASMX WebService to expose Entity objects from Entity Framework... then the ASMX Webservice does not  include object graphs, one work around is to use Facade pattern or to use WCF Service. The other important aspect of using ASMX Web Services along with Entity Framework is that the ASMX Client is not aware of the existence of EF v1 since the client solely deals with C# objects (not EntityObjects or ObjectContext). Since the client is not aware of the ObjectContext hence the client cannot participate in change tracking since the client only receives the Current Values and not the Orginal values when the service sends the the Entity objects to the client. Thus there are 2 drawbacks to using EntityFramework with ASMX Web Service: 1. Object state is not maintained... so to overcome this limitation we need insert/update single entity at a time and retrieve the original values for the entity being updated on the server/service end before calling Save Changes. 2. ASMX does not maintain object graphs... i.e. Customer.Reservations or Customer.Reservations.Trip relationships are not maintained. Thus you need to send these relationships separately from service to client. WCF Web Service overcomes the object graph limitation of ASMX Web Service, but we need to insure that we are populating all the non-null scalar properties of all the objects in the object graph before calling Update. WCF Web service still cannot overcome the second limitation of tracking changes to entities at the client end. Also note that the "Customer" class in the Client is very different from the "Customer" class in the Entity Framework Model Entities. They are incompatible with each other hence we cannot cast one to the other. However the .NET Framework translates the client "Customer" Entity to the EFv1 Model "customer" Entity once the entity is serialzed back on the ASMX server end. If you need change tracking enabled on the client then we need to use WCF Data Services which is available with VS 2010. ====================================================================================================== In WCF when adding an object that has relationships, the framework assumes that every object in the object graph needs to be added to store. for e.g. in a Customer.Reservations.Trip object graph, when a Customer Entity is added to the store, the EFv1 assumes that it needs to a add a Reservations collection and also Trips for each Reservation. Thus if we need to use existing Trips for reservations then we need to insure that we null out the Trip object reference from Reservations and set the TripReference to the EntityKey of the desired Trip instead. ====================================================================================================== Understanding Relationships and Associations in EFv1 The Golden Rule of EF is that it does not load entities/relationships unless you ask it to explicitly do so. However there is 1 exception to this rule. This exception happens when you attach/detach entities from the ObjectContext. If you detach an Entity in a ObjectGraph from the ObjectContext, then the ObjectContext removes the ObjectStateEntry for this Entity and all the relationship Objects associated with this Entity. For e.g. in a Customer.Order.OrderDetails if the Customer Entity is detached from the ObjectContext then you cannot traverse to the Order and OrderDetails Entities (that still exist in the ObjectContext) from the Customer Entity(which does not exist in the Object Context) Conversely, if you JOIN a entity that is not in the ObjectContext with a Entity that is in the ObjContext then the First Entity will automatically be added to the ObjContext since relationships for the 2 Entities need to exist in the ObjContext. ========================================================= You cannot attach an EntityCollection to an entity through its navigation property for e.g. you cannot code myContact.Addresses = myAddressEntityCollection ========================================================== Cascade Deletes in EDM: The Designer does not support specifying cascase deletes for a Entity. To enable cascasde deletes on a Entity in EDM use the Association definition in CSDL for the Entity. for e.g. SalesOrderDetail (SOD) has a Foreign Key relationship with SalesOrderHeader (SalesOrderHeader 1 : SalesOrderDetail *) if you specify a cascade Delete on SalesOrderHeader Entity then calling deleteObject on SalesOrderHeader (SOH) Entity will send delete commands for SOH record and all the SOD records that reference the SOH record. ========================================================== As a good design practise, if you use Cascade Deletes insure that Cascade delete facet is used both in the EDM as well as in the database. Even though it is not absolutely mandatory to have Cascade deletes on both Database and EDM (since you can see that just the Cascade delete spec on the SOH Entity in EDM will insure that SOH record and all related SOD records will be deleted from the database ... even though you dont have cascade delete configured in the database in the SOD table) ============================================================== Maintaining relationships in Code When Setting a Navigation property of a Entity (for e.g. setting the Contact Navigation property of Address Entity) the following rules apply : If both objects are detached, no relationship object will be created. You are simply setting a property the CLR way. If both objects are attached, a relationship object will be created. If only one of the objects is attached, the other will become attached and a relationship object will be created. If that detached object is new, when it is attached to the context its EntityState will be Added. One important rule to remember regarding synchronizing the EntityReference.Value and EntityReference.EntityKey properties is that when attaching an Entity which has a EntityReference (e.g. Address Entity with ContactReference) the Value property will take precedence and if the Value and EntityKey are out of sync, the EntityKey will be updated to match the Value. ====================================================== If you call .Load() method on a detached Entity then the .Load() operation will throw an exception. There is one exception to this rule. If you load entities using MergeOption.NoTracking, you will be able to call .Load() on such entities since these Entities are accessible by the ObjectContext. So the bottomline is that we need Objectontext to be able to call .Load() method to do deffered loading on EntityReference or EntityCollection. Another rule to remember is that you cannot call .Load() on entities that have a EntityState.Added State since the ObjectContext uses the EntityKey of the Primary (Parent) Entity when loading the related (Child) Entity (and not the EntityKey of the child (even if the EntityKey of the child is present before calling .Load()) ====================================================== You can use ObjContext.Add() to add a entity to the ObjContext and set the EntityState of the new Entity to EntityState.Added. here no relationships are added/updated. You can also use EntityCollection.Add() method to add an entity to another entity's related EntityCollection for e.g. contact has a Addresses EntityCollection so to add a new address use contact.Addresses.Add(newAddress) to add a new address to the Addresses EntityCollection. Note that if the entity does not already exist in the ObjectContext then calling contact.Addresses.Add(myAddress) will cause a new Address Entity to be added to the ObjContext with EntityState.Added and it will also add a RelationshipEntry (a relationship object) with EntityState.Added which connects the Contact (contact) with the new address newAddress. Note that if the entity already exists in the Objectcontext (being part theOtherContact.Addresses Collection), then calling contact.Addresses.Add(existingAddress) will add 2 RelationshipEntry objects to the ObjectStateEntry Collection, one with EntityState.Deleted and the other with EntityState.Added. This implies that the existingAddress Entity is removed from the theOtherContact.Addresses Collection and Added to the contact.Addresses Collection..effectively reassigning the address entity from the theOtherContact to "contact". This is called moving an existing entity to a new object graph. ====================================================== You usually use ObjectContext.Attach() and EntityCollection.Attach() methods usually when you need to reconstruct the ObjectGraph after deserializing the objects as received from a ASMX Web Service Client. Attach is usually used to connect existing Entities in the ObjectContext. When EntityCollection.Attach() is called the EntityState of the RelationshipEntry (the relationship object) remains as EntityState.unchanged whereas when EntityCollection.Add() method is called the EntityState of the relationship object changes to EntityState.Added or EntityState.Deleted as the situation demands. ========================================================= LINQ To Entities Tips: Select Many does Inner Join by default.   for e.g. from c in Contact from a in c.Address select c ... this will do a Inner Join between the Contacts and Addresses Table and return only those Contacts that have a Address. ======================================================== Group Joins Do LEFT Join by default. e.g. from a in Address join c in Contact ON a.Contact.ContactID == c.ContactID Into g WHERE a.CountryRegion == "US" select g; This query will do a left join on the Contact table and return contacts that have a address in "US" region The following query : from c in Contact join a in Address.Where(a1 => a1.CountryRegion == "US") on c.ContactID  equals a.Contact.ContactID into addresses select new {c, addresses} will do a left join on the Address table and return All Contacts. In these Contacts only those will have its Address EntityCollection Populated which have a Address in the "US" region, the other contacts will have 0 Addresses in the Address collection (even if addresses for those contacts exist in the database but are in a different region) ======================================================== Linq to Entities does not support DefaultIfEmpty().... instead use .Include("Address") Query Builder method to do a Left JOIN or use Group Joins if you need more control like Filtering on the Address EntityCollection of Contact Entity =================================================================== Use CreateSourceQuery() on the EntityReference or EntityCollection if you need to add filters during deferred loading of Entities (Deferred loading in EFv1 happens when you call Load() method on the EntityReference or EntityCollection. for e.g. var cust=context.Contacts.OfType<Customer>().First(); var sq = cust.Reservations.CreateSourceQuery().Where(r => r.ReservationDate > new DateTime(2008,1,1)); cust.Reservations.Attach(sq); This populates only those reservations that are older than Jan 1 2008. This is the only way (in EFv1) to Attach a Range of Entities to a EntityCollection using the Attach() method ================================================================== If you need to get the Foreign Key value for a entity e.g. to get the ContactID value from a Address Entity use this :                                address.ContactReference.EntityKey.EntityKeyValues.Where(k=> k.Key == "ContactID")

  • Can notes/to-dos in code comments sent to code-reviews result in an effective refactoring process?

    - by dukeofgaming
    I want to start/improve a culture of collective code ownership at my company but at a geographically distributed level... I'd say there is some current collective code-ownership mentality, but only at single geographical sites. This is a follow-up to this question: What is the politically correct way of refactoring other's code? I'm just wondering if submitting *just code comments* for code reviews (we have ReviewBoard, possibly upgrading to Crucible) could actually be an effective mechanism to get the conversation started on improving code, without having others feel territorial about their code. For example, if I add: //ToDo: Refactor this code and that code because of reasons X and Y Then, submit it for code review, and it gets accepted... it could be considered as an agreement (which I think is sometimes harder to get with new code up front). At the same time, the author (and others) might have an easier time digesting and accepting the proposal; rejecting a proposal because it might break things will not longer be a valid reason and therefore the fear of making a change is lost... and at the same time, do not invest 10 hours optimizing something that no one thinks it is worth it and opposes to it just out of fear. This is all conjecture, but I'm feeling something like this (submitting refactoring notes in code comments at the code-review process) would work. Has anyone done something like this in practice?, if so, what have been the results?

  • Exception Handling

    - by raghu.yadav
    Here is the few links on which andre had demonstrateddifferences-of-handling-jboexception-in handling-exceptions-in-oracle-ui-shell However in this post we can see how to display exception in popup being in the same page. I use similar usecase as andre however we'll not be using Exception Handling property from taskflow, instead we use popup and invoke the same programmatically. This is a dynamic region example where user can select jobs or locations links to edit the records of corresponding tables being in the same page and click commit to save changes. To generate exception we deliberately change commit to CommitAction in commit action binding code created in the bean (same as andre) and catch the exception and add brief description of exception into #{pageFlowScope.message}. Drop Popup component after Commit button and add dialog within in popup button, bind the popup component to backing bean and invoke the same in catch clause as shown below. public String Commit() { try{ BindingContainer bindings = getBindings(); OperationBinding operationBinding = bindings.getOperationBinding("CommitAction"); Object result = operationBinding.execute(); if (!operationBinding.getErrors().isEmpty()) { return null; } }catch (NullPointerException e) { setELValue("#{pageFlowScope.message}", "NullPointerException..."); e.printStackTrace(); String popupId = this.getPopup().getClientId(FacesContext.getCurrentInstance()); PatternsPublicUtil.invokePopup(popupId); } return null; } } private void setELValue(String el, String value) { FacesContext facesContext = FacesContext.getCurrentInstance(); ELContext elContext = facesContext.getELContext(); ExpressionFactory expressionFactory = facesContext.getApplication().getExpressionFactory(); ValueExpression valueExp = expressionFactory.createValueExpression(elContext, el, Object.class); valueExp.setValue(elContext, value); } .

  • The Evolution of an Era: Customer Experience in Retail

    - by Michael Hylton
    Two New Studies Point to the Direction Retailers are Taking in their CX Initiatives. Is it the Right Direction? The sheer velocity of change in retailing and customer behavior is forcing retailers to reinvigorate, expand and sharpen their vital Customer Experience (CX) strategies. Customers are becoming increasingly dynamic as they race to embrace the newest digital channels; shop in new ways on mobile devices, including smartphones and tablets, on the Web and in the store; share experiences socially; and interact with their preferred brands in new ways. Retailers are stepping up to their customers as they and their competitors create new modes of customer interaction. Underpinning these changes are vast quantities of customer data as customers flood digital channels and the social sphere. The informed retailer must now understand what their priorities are and what they should be for the future. To better understand this, Tata Consultancy Services (TCS) and Oracle independently launched CX-focused surveys to uncover what retailing leadership found important today. By comparing the results of these two studies together, we can further discover new insights about the industry. Click here to download this informative white paper.

  • Oracle UPK Content Development Tool Settings

    - by [email protected]
    Oracle UPK Content Development tool settings: Before developing UPK content, your UPK Developer needs to be configured with certain standard settings to ensure the content will have a uniform look. To set the options: 1. Open the UPK Developer. 2. Click the Tools menu. 3. Click Options. After you configure the UPK Options, you can share these preferences with other content developers by exporting them to an .ops file. This is particularly useful in workgroup environments where multiple authors are working on the same content that requires consistent output regardless of who authored the content. (To learn more about Exporting/Importing Content Defaults refer to the Content Development.pdf guide that is delivered with the UPK Developer.) Here is a list of a few UPK Developer tool settings that Oracle UPK Content Developers use to develop UPK pre-built content: Screen resolution is set to 1024 x 768. See It mode frame delay is set to 5 seconds. Know It Required % is set to 70% and all three levels of remediation are selected. We opt to automatically record keyboard shortcuts. We use the default settings for the Bubble icon and Pointer position. Bubble color is yellow (Red = 255, Green = 255, Blue = 128). Bubble text is Verdana, Regular, 9 pt. ***Intro and end frame settings match the bubble settings Note: The Content Defaults String Input Settings will change based on which application (interface) you are recording against. For example here is a list of settings for different Oracle applications: • Agile - Microsoft Sans Serif, Regular, 8 • EBS - Microsoft Sans Serif, Regular, 10 • Hyperion - Microsoft Sans Serif, Regular, 8 • JDE E1 - Arial, Regular, 10 • PeopleSoft - Arial, Regular, 9 • Siebel - Arial, Regular, 8 Remember, it is recommended that you set the content defaults before you add documents and record content. When the content defaults are changed, existing documents are not affected and continue to use the defaults that were in effect when those documents were created. - Kathryn Lustenberger, Oracle UPK & Tutor Outbound Product Management

  • SQL SERVER – Effect of Collation on Resultset – SQL in Sixty Seconds #026 – Video

    - by pinaldave
    Collation is a very important concept but often ignored. I have often seen developers either not understanding this or ignored it – this is plain wrong. In simple word we can say Collation is the language or interpreting done by SQL Server. Well, in today’s SQL in Sixty Seconds we are going to observe how collation affects the resultset. Today’s blog post is inspired from my earlier blog post SQL SERVER – Effect of Case Sensitive Collation on Resultset. I strongly encourage you to read this earlier blog post for sample code as well additional explanation related to the concept shared in today’s SQL in Sixty Seconds. Here is the code used in the video. USE TempDB GO -- Sample Data Building CREATE TABLE ColTable (Col1 VARCHAR(15) COLLATE Latin1_General_CI_AS, Col2 VARCHAR(14) COLLATE Latin1_General_CS_AS) ; INSERT ColTable(Col1, Col2) VALUES ('Apple','Apple'), ('apple','apple'), ('pineapple','pineapple'), ('Pineapple','Pineapple'); GO -- Retrieve Data SELECT * FROM ColTable GO -- Retrieve Data SELECT * FROM ColTable ORDER BY Col1 GO -- Retrieve Data SELECT * FROM ColTable ORDER BY Col2 GO -- Clean up DROP TABLE ColTable GO Related Tips in SQL in Sixty Seconds: SQL SERVER – Effect of Case Sensitive Collation on Resultset Example of Width Sensitive and Width Insensitive Collation Collation and Collation Sensitivity – Quiz – Puzzle – 6 of 31 Change Collation of Database Column – T-SQL Script Find Collation of Database and Table Column Using T-SQL Default Collation of SQL Server 2008 Cannot resolve collation conflict for equal to operation If we like your idea we promise to share with you educational material.

  • Unity3D and Texture2D. GetPixel returns wrong values

    - by Heisenbug
    I'm trying to use Texture2D set and get colors, but I encountered a strange behavior. Here's the code to reproduce it: Texture2D tex = new Texture2D(2,2, TextureFormat.RGBA32 ,false); Color col = new Color(1.0f,0.5f,1.0f,0.5f); //col values: 1.00, 0.500, 1.00, 0.500 tex.setPixel(0,0,col); Color colDebug = tex.getPixel(0,0); //col values: 1.00, 0.502, 1.00, 0.502 The Color retrieved with getPixel is different from the Color set before. I initially thought about float approximation, but when inspectin col the value stored are correct, so can't be that reason. It sounds weird even a sampling error because the getValue returns a value really similar that not seems to be interpolated with anything else. Anyway I tried even to add these lines after building the texture but nothing change: this.tex.filterMode = FilterMode.Point; this.tex.wrapMode = TextureWrapMode.Clamp; this.tex.anisoLevel = 1; What's my mistake? What am I missing? In addition to that. I'm using tex to store Rect coordinates returned from atlas generation, in order to be able of retriving the correct uv coordinate of an atlas inside a shader. Is this a right way to go?

  • Configure TFS portal afterwards

    Update #1 January 8th, 2010: There is an updated post on this topic for Beta 2: http://www.ewaldhofman.nl/post/2009/12/10/Configure-TFS-portal-afterwards-Beta-2.aspx Update #2 October 10th, 2010: In the new Team Foundation Server Power Tools September 2010, there is now a command to create a portal. tfpt addprojectportal   Add or move portal for an existing team project Usage: tfpt addprojectportal /collection:uri                              /teamproject:"project name"                              /processtemplate:"template name"                              [/webapplication:"webappname"]                              [/relativepath:"pathfromwebapp"]                              [/validate]                              [/verbose] /collection Required. URL of Team Project Collection. /teamproject Required. Specifies the name of the team project. /processtemplate Required. Specifies that name of the process template. /webapplication The name of the SharePoint Web Application. Must also specify relativepath. /relativepath The path for the site relative to the root URL for the SharePoint Web Application. Must also specify webapplication. /validate Specifies that the user inputs are to be validated. If specified, only validation will be done and no portal setting will be changed. /verbose Switches on the verbose mode. I created a new Team Project in TFS 2010 Beta 1 and choose not to configure SharePoint during the creation of the Team Project. Of course I found out fairly quickly that a portal for TFS is very useful, especially the Iteration and the Product backlog workbooks and the dashboard reports. This blog describes how you can configure the sharepoint portal afterwards. Update: September 9th, 2009 Adding the portal afterwards is much easier as described below. Here are the steps Step 1: Create a new temporary project (with a SharePoint site for it). Open the Team Explorer Right click in the Team Explorer the root node (i.e. the project collection) Select "New team project" from the menu Walk throught he wizard and make sure you check the option to create the portal (which is by default checked) Step 2: Disable the site for the new project Open the Team Explorer Select the team project you created in step 1 In the menu click on Team -> Show Project Portal. In the menu click on Team -> Team Project Settings -> Portal Settings... The following dialog pops up Uncheck the option "Enable team project portal" Confirm the dialog with OK Step 3: Enable the site for the original one. Point it to the newly created site. Open the Team Explorer Select the team project you want to add the portal to In the menu open Team -> Team Project Settings -> Portal Settings... The same dialog as in step 2 pops up Check the option "Enable team project portal" Click on the "Configure URL" button The following dialog pops up   In the dialog select in the combobox of the web application the TFS server Enter in the Relative site path the text "sites/[Project Collection Name]/[Team Project Name created in step 1]" Confirm the "Specify an existing SharePoint Site" with OK Check the "Reports and dashboards refer to data for this team project" option Confirm the dialog "Project Portal Settings" with OK Step 4: Delete the temporary project you created. In Beta 1, I have found no way to delete a team project. Maybe it will be available in TFS 2010 Beta 2. Original post Step 1: Create new portal site Go to the sharepoint site of your project collection (/sites//default.aspx">/sites//default.aspx">http://<servername>/sites/<project_collection_name>/default.aspx) Click on the Site Actions at the left side of the screen and choose the option Site Settings In the site settings, choose the Sites and workspaces option Create a new site Enter the values for the Title, the description, the site address. And choose for the TFS2010 Agile Dashboard as template. Create the site, by clicking on the Create button Step 2: Integrate portal site with team project Open Visual Studio Open the Team Explorer (View -> Team Explorer) Select in the Team Explorer tool window the Team Project for which you are create a new portal Open the Project Portal Settings (Team -> Team Project Settings -> Portal Setings...) Check the Enable team project portal checkbox Click on Configure URL... You will get a new dialog as below Enter the url to the TFS server in the web application combobox And specify the relative site path: sites/<project collection>/<site name> Confirm with OK Check in the Project Portal Settings dialog the checkbox "Reports and dashboards refer to data for this team project" Confirm the settings with OK (this takes a while...) When you now browse to the portal, you will see that the dashboards are now showing up with the data for the current team project. Step 3: Download process template To get a copy of the documents that are default in a team project, we need to have a fresh set of files that are not attached to a team project yet. You can do that with the following steps. Start the Process Template Manager (Team -> Team Project Collection Settings -> Process Template Manager...) Choose the Agile process template and click on download Choose a folder to download Step 4: Add Product and Iteration backlog Go to the Team Explorer in Visual Studio Make sure the team project is in the list of team projects, and expand the team project Right click the Documents node, and choose New Document Library Enter "Shared Documents", and click on Add Right click the Shared Documents node and choose Upload Document Go the the file location where you stored the process template from step 3 and then navigate to the subdirectory "Agile Process Template 5.0\MSF for Agile Software Development v5.0\Windows SharePoint Services\Shared Documents\Project Management" Select in the Open Dialog the files "Iteration Backlog" and "Product Backlog", and click Open Step 5: Bind Iteration backlog workbook to the team project Right click on the "Iteration Backlog" file and select Edit, and confirm any warning messages Place your cursor in cell A1 of the Iteration backlog worksheet Switch to the Team ribbon and click New List. Select your Team Project and click Connect From the New List dialog, select the Iteration Backlog query in the Workbook Queries folder. The final step is to add a set of document properties that allow the workbook to communicate with the TFS reporting warehouse. Before we create the properties we need to collect some information about your project. The first piece of information comes from the table created in the previous step.  As you collect these properties, copy them into notepad so they can be used in later steps. Property How to retrieve the value? [Table name] Switch to the Design ribbon and select the Table Name value in the Properties portion of the ribbon [Project GUID] In the Visual Studio Team Explorer, right click your Team Project and select Properties.  Select the URL value and copy the GUID (long value with lots of characters) at the end of the URL [Team Project name] In the Properties dialog, select the Name field and copy the value [TFS server name] In the Properties dialog, select the Server Name field and copy the value [UPDATE] I have found that this is not correct: you need to specify the instance of your SQL Server. The value is used to create a connection to the TFS cube. Switch back to the Iteration Backlog workbook. Click the Office button and select Prepare – Properties. Click the Document Properties – Server drop down and select Advanced Properties. Switch to the Custom tab and add the following properties using the values you collected above. Variable name Value [Table name]_ASServerName [TFS server name] [Table name]_ASDatabase tfs_warehouse [Table name]_TeamProjectName [Team Project name] [Table name]_TeamProjectId [Project GUID] Click OK to close the properties dialog. It is possible that the Estimated Work (Hours) is showing the #REF! value. To resolve that change the formula with: =SUMIFS([Table name][Original Estimate]; [Table name][Iteration Path];CurrentIteration&"*";[Table name][Area Path];AreaPath&"*";[Table name][Work Item Type]; "Task") For example =SUMIFS(VSTS_ab392b55_6647_439a_bae4_8c66e908bc0d[Original Estimate]; VSTS_ab392b55_6647_439a_bae4_8c66e908bc0d[Iteration Path];CurrentIteration&"*";VSTS_ab392b55_6647_439a_bae4_8c66e908bc0d[Area Path];AreaPath&"*";VSTS_ab392b55_6647_439a_bae4_8c66e908bc0d[Work Item Type]; "Task") Also the Total Remaining Work in the Individual Capacity table may contain #REF! values. To resolve that change the formula with: =SUMIFS([Table name][Remaining Work]; [Table name][Iteration Path];CurrentIteration&"*";[Table name][Area Path];AreaPath&"*";[Table name][Assigned To];[Team Member];[Table name][Work Item Type]; "Task") For example =SUMIFS(VSTS_ab392b55_6647_439a_bae4_8c66e908bc0d[Remaining Work]; VSTS_ab392b55_6647_439a_bae4_8c66e908bc0d[Iteration Path];CurrentIteration&"*";VSTS_ab392b55_6647_439a_bae4_8c66e908bc0d[Area Path];AreaPath&"*";VSTS_ab392b55_6647_439a_bae4_8c66e908bc0d[Assigned To];[Team Member];VSTS_ab392b55_6647_439a_bae4_8c66e908bc0d[Work Item Type]; "Task") Save and close the workbook. Step 6: Bind Product backlog workbook to the team project Repeat the steps for binding the Iteration backlog for thiw workbook too. In the worksheet Capacity, the formula of the Storypoints might be missing. You can resolve it with: =IF([Iteration]="";"";SUMIFS([Table name][Story Points];[Table name][Iteration Path];[Iteration]&"*")) Example =IF([Iteration]="";"";SUMIFS(VSTS_487f1e4c_db30_4302_b5e8_bd80195bc2ec[Story Points];VSTS_487f1e4c_db30_4302_b5e8_bd80195bc2ec[Iteration Path];[Iteration]&"*"))

  • Why is IaaS important in Azure&hellip;

    - by Steve Loethen
    Three weeks ago, Microsoft released the next phase of Azure.  I have had several clients waiting on this release.  The fact that they have been waiting and are now more receptive to looking at the cloud.  Customers expressed fear of the unknown.  And a fear of lack of control, even when that lack of control also means a huge degree of flexibility to innovate with concerns about the underlying infrastructure.  I think IaaS will be that “gateway drug” to get customers who have been hesitant to take another look at the cloud.  The dialog can change from the cloud being this big scary unknown to a resource for workloads.  The conversations should have always been, and can know be even stronger, geared toward the following points: 1) The cloud is not unicorns and glitter, the cloud is resources.  Compute, storage, db’s, services bus, cache…..  Like many of the resources we have on-premise.  Not magic, just another resource with advantages and obstacles like any other resource. 2) The cloud should be part of the conversation for any new project.  All of the same criteria should be applied, on-premise or off.  Cost, security, reliability, scalability, speed to deploy, cost of licenses, need to customize image, complex workloads.  We have been having these discussions for years when we talk about on-premise projects.  We make decisions on OS’s, Databases, ESB’s, configuration and products based on a myriad of factors.  We use the same factors but now we have a additional set of resources to consider in our process. 3) The cloud is a great solution looking for some interesting problems.  It is our job to recognize the right problems that fit into the cloud, weigh the factors and decide what to do. IaaS makes this discussion easier, offers more choices, and often choices that many enterprises will find more better than PaaS.  Looking forward to helping clients realize the power of the cloud.

  • Ada and 'The Book'

    - by Phil Factor
    The long friendship between Charles Babbage and Ada Lovelace created one of the most exciting and mysterious of collaborations ever to have resulted in a technological breakthrough. The fireworks that created by the collision of two prodigious mathematical and creative talents resulted in an invention, the Analytical Engine, which went on to change society fundamentally. However, beyond that, we just don't know what the bulk of their collaborative work was about:;  it was done in strictest secrecy. Even the known outcome of their friendship, the first programmable computer, was shrouded in mystery. At the time, nobody, except close friends and family, had any idea of Ada Byron's contribution to the invention of the ‘Engine’, and how to program it. Her great insight was published in August 1843, under the initials AAL, standing for Ada Augusta Lovelace, her title then being the Countess of Lovelace. It was contained in a lengthy ‘note’ to her translation of a publication that remains the best description of Babbage's amazing Analytical Engine. The secret identity of the person behind those enigmatic initials was finally revealed by Prince de Polignac who, seventy years later, wrote to Ada's daughter to seek confirmation that her mother had, indeed, been the author of the brilliant sentences that described so accurately how Babbage's mechanical computer could be programmed with punch-cards. L.F. Menabrea's paper on the Analytical Engine first appeared in the 'Bibliotheque Universelle de Geneve' in October 1842, and Ada translated it anonymously for Taylor's 'Scientific Memoirs'. Charles Babbage was surprised that she had not written an original paper as she already knew a surprising amount about the way the machine worked. He persuaded her to at least write some explanatory notes. These notes ended up extending to four times the length of the original article and represented the first published account of how a machine could be programmed to perform any calculation. Her example of programming the Bernoulli sequence would have worked on the Analytical engine had the device’s construction been completed, and gave Ada an unassailable claim to have invented the art of programming. What was the reason for Ada's secrecy? She was the only legitimate child of Lord Byron, who was probably the best known celebrity of the age, so she was already famous. She was a senior aristocrat, with titles, a fortune in money and vast estates in the Midlands. She had political influence, and was the cousin of Lord Melbourne, who was the Prime Minister at that time. She was friendly with the young Queen Victoria. Her mathematical activities were a pastime, and not one that would be considered by others to be in keeping with her roles and responsibilities. You wouldn't dare to dream up a fictional heroine like Ada. She was dazzlingly beautiful and talented. She could speak several languages fluently, and play some musical instruments with professional skill. Contemporary accounts refer to her being 'accomplished in science, art and literature'. On top of that, she was a brilliant mathematician, a talent inherited from her mother, Annabella Milbanke. In her mother's circle of literary and scientific friends was Charles Babbage, and Ada's friendship with him dates from her teenage zest for Mathematics. She was one of the first people he'd ever met who understood what he had attempted to achieve with the 'Difference Engine', and with whom he could converse as intellectual equals. He arranged for her to have an education from the most talented academics in the country. Ada melted the heart of the cantankerous genius to the point that he became a faithful and loyal father-figure to her. She was one of the very few who could grasp the principles of the later, and very different, ‘Analytical Engine’ which was designed from the start to tackle a variety of tasks. Sadly, Ada Byron's life ended less than a decade after completing the work that assured her long-term fame, in November 1852. She was dying of cancer, her gambling habits had caused her to run up huge debts, she'd had more than one affairs, and she was being blackmailed. Her brilliant but unempathic mother was nursing her in her final illness, destroying her personal letters and records, and repaying her debts. Her husband was distraught but helpless. Charles Babbage, however, maintained his steadfast paternalistic friendship to the end. She appointed her loyal friend to be her executor. For years, she and Babbage had been working together on a secret project, known only as 'The Book'. We have a clue to what it was in a letter written by her nine years earlier, on 11th August 1843. It was a joint project by herself and Lord Lovelace, her husband, and was intended to involve Babbage's 'undivided energies'. It involved 'consulting your Engine' (it required Babbage’s computer). The letter gives no hint about the project except for the high-minded nature of its purpose, and its highly mathematical nature.  From then on, the surviving correspondence between the two gives only veiled references to 'The Book'. There isn't much, since Babbage later destroyed any letters that could have damaged her reputation within the Establishment. 'I cannot spare the book today, which I am very sorry for. At the moment I want it for constant reference, but I think you can have it tomorrow' (Oct 1844)  And 'I will send you the book directly, and you can say, when you receive it, how long you will want to keep it'. (Nov 1844)  The two of them were obviously intent on the work: She writes, four years later, 'I have an engagement for Wednesday which will prevent me from attending to your wishes about the book' (Dec 1848). This was something that they both needed to work on, but could not do in parallel: 'I will send the book on Tuesday, and it can be left with you till Friday' (11 Feb 1849). After six years work, it had been so well-handled that it was beginning to fall apart: 'Don't forget the new cover you promised for the book. The poor book is very shabby and wants one' (20 Sept 1849). So what was going on? The word 'book' was not a code-word: it was a real book, probably a 'printer's blank', plain paper, but properly bound so printers and publishers could show off how the published work might look. The hints from the correspondence are of advanced mathematics. It is obvious that the book was travelling between them, back and forth, each one working on it for less than a week before passing it back. Ada and her husband were certainly involved in gambling large sums of money on the horses, and so most biographers have concluded that the three of them were trying to calculate the mathematical odds on the horses. This theory has three large problems. Firstly, Ada's original letter proposing the project refers to its high-minded nature. Babbage was temperamentally opposed to gambling and would scarcely have given so much time to the project, even though he was devoted to Ada. Secondly, Babbage would have very soon have realized the hopelessness of trying to beat the bookies. This sort of betting never attracts his type of intellectual background. The third problem is that any work on calculating the odds on horses would not need a well-thumbed book to pass back and forth between them; they would have not had to work in series. The original project was instigated by Ada, along with her husband, William King-Noel, 1st Earl of Lovelace. Charles Babbage was invited to join the project after the couple had come up with the idea. What could William have contributed? One might assume that William was a Bertie Wooster character, addicted only to the joys of the turf, but this was far from the truth. He was a scientist, a Cambridge graduate who was later elected to be a Fellow of the Royal Society. After Eton, he went to Trinity College, Cambridge. On graduation, he entered the diplomatic service and acted as secretary under Lord Nugent, who was Lord Commissioner of the Ionian Islands. William was very friendly with Babbage too, able to discuss scientific matters on equal terms. He was a capable engineer who invented a process for bending large timbers by the application of steam heat. He delivered a paper to the Institution of Civil Engineers in 1849, and received praise from the great engineer, Isambard Kingdom Brunel. As well as being Lord Lieutenant of the County of Surrey for most of Victoria's reign, he had time for a string of scientific and engineering achievements. Whatever the project was, it is unlikely that William was a junior partner. After Ada's death, the project disappeared. Then, two years later, Babbage, through one of his occasional outbursts of temper, demonstrated that he was able to decrypt one of the most powerful of secret codes, Vigenère's autokey cipher.  All contemporary diplomatic and military messages used a variant of this cipher. Babbage had made three important discoveries, namely, the mathematical law of this cipher, the principle of the key periodicity, and the technique of the symmetry of position. The technique is now known as the Kasiski examination, also called the Kasiski test, but Babbage got there first. At one time, he listed amongst his future projects, the writing of a book 'The Philosophy of Decyphering', but it never came to anything. This discovery was going to change the course of history, since it was used to decipher the Russians’ military dispatches in the Crimean war. Babbage himself played a role during the Crimean War as a cryptographical adviser to his friend, Rear-Admiral Sir Francis Beaufort of the Admiralty. This is as much as we can be certain about in trying to make sense of the bulk of the time that Charles Babbage and Ada Lovelace worked together. Nine years of intensive work, involving the 'Engine' and a great deal of mathematics and research seems to have been lost: or has it? I've argued in the past http://www.simple-talk.com/community/blogs/philfactor/archive/2008/06/13/59614.aspx that the cracking of the Vigenère autokey cipher, was a fundamental motive behind the British Government's support and funding of the 'Difference Engine'. The Duke of Wellington, whose understanding of the military significance of being able to read enemy dispatches, was the most steadfast advocate of the project. If the three friends were actually doing the work of cracking codes by mathematical techniques that used the techniques of key periodicity, and symmetry of position (the use of a book being passed quickly to and fro is very suggestive), intending to then use the 'Engine' to do the routine cracking of each dispatch, then this is a rather different story. The project was Ada and William's idea. (William had served in the diplomatic service and would be familiar with the use of codes). This makes Ada Lovelace the initiator of a project which, by giving both Britain, and probably the USA, a diplomatic and military advantage in the second part of the Nineteenth century, changed world history. Ada would never have wanted any credit for cracking the cipher, and developing the method that rendered all contemporary military and diplomatic ciphering techniques nugatory; quite the reverse. And it is clear from the gaps in the record of the letters between the collaborators that the evidence was destroyed, probably on her request by her irascible but intensely honorable executor, Charles Babbage. Charles Babbage toyed with the idea of going public, but the Crimean war put an end to that. The British Government had a valuable secret, and intended to keep it that way. Ada and Charles had quite often discussed possible moneymaking projects that would fund the development of the Analytic Engine, the first programmable computer, but their secret work was never in the running as a potential cash cow. I suspect that the British Government was, even then, working on the concealment of a discovery whose value to the nation depended on it remaining so. The success of code-breaking in the Crimean war, and the American Civil war, led to the British and Americans  subsequently giving much more weight and funding to the science of decryption. Paradoxically, this makes Ada's contribution even closer to the creation of Colossus, the first digital computer, at Bletchley Park, specifically to crack the Nazi’s secret codes.
