• Alternative to Windows Azure tables out of the cloud

  - by John Grey

  Hi :) I'm developing a .NET app, which needs to run both on Azure and on regular Windows Servers(2003). It needs to store a few GB of data and SQL Azure is too expensive for me, so I'll use Azure tables in the cloud version. Can you recommend a storage solution, which will run on standalone servers and have an API and behavior similar to Azure tables? From what I've seen Server AppFabric does not include Tables. TIA

• Radial Grid Search Algorithm

  - by grey

  I'm sure there's a clean way to do this, but I'm probably not using the right keywords for find it. So let's say I have a grid. Starting from a position on the grid, return all of the grid coordinates that fall within a given distance. So I call something like: getCoordinates( currentPosition, distance ) And for each coordinate, starting from the initial position, add all cardinal directions, and then add the spaces around those and so forth until the distance is reached. I imagine that on a grid this would look like a diamond.

• Include a unique URL in EXE

  - by John Grey

  Hi :) I want to give users of my site the ability to upload their software/hardware configuration automatically on Windows. So I'm thinking of having an EXE file download, and somehow put in that EXE a unique URL for each user. When the data is collected, the program would just posts some JSON to that URL. How can I do it? I'm most familiar with .NET platform. Tools like this do exist, for example Blizzard uses this approach for their beta test enroll. Each user downloads a slightly different EXE. TIA

• .gitignore not working for me

  - by John Grey

  Hi, I'm trying to create a new git repository from existing folder. I've created a .gitignore file in the root of the folder. But if I say 'git add *' 'git commit' 'git push' files that should be ignored still get commited to the remote repository. I'm on Windows. Also I've bought a license for SmartGIT. It also seems to ignore .gitignore. I have to manually select which new files to commit. What am I doing wrong?

• Safari on the iPhone & iPad gives colour feedback on touch, I want to stop this.

  - by Owen

  Clicking on an element which has a Javascript handler makes the element go have a 'grey overlay'. This is normally fine but I'm using event delegation to handle the touchdown events of many child elements. Because of the delegation the 'grey overlay' is appearing over the parent element and looks bad and confusing. I could attach event handlers to the individual elements to avoid the problem but this would be computationally very wasteful. I'd rather have some webkit css property that I can override to turn it off. I already have visual feedback in my app so the 'grey overlay' is not needed. Any ideas?

• Learning C++ from AS3

  - by grey

  I'm a decent AS3 programmer. I work in games, and that is my reason for programming. While there is much I can accomplish with Adobe AIR, my understanding at this point is that learning C++ is probably a good direction to take. I would learn a lot of valuable lower level programming if I needed it down the road, and I would have an easier time learning other C oriented languages. I see a lot of information for people looking to learn AS3 who know C++, but not the other way around. Why C++? Cross platform compatibility is important to me, so I'm not particularly interested in C# or Objective-C at this junction. I'm also aware of HaXe, and while I love the concept, after doing some research I'm worried about investing a lot of time into something so recent with limited learning resources and documentation. I'm looking for advice and resources (books, articles) related to this topic. Thanks in advance!

• AS3/AIR: Managing Run-Time Image Data

  - by grey

  I'm developing a game with AS3 and AIR. I will have a large-ish quantity of images that I need to load for display elements. It would be nice not to embed all of the images that the game needs, thereby avoiding having them all in memory at once. That's okay in smaller projects, but doesn't make sense here. I'm curious about strategies for loading images during run time. Since all of the files are quite small and local ( in my current project ) loading them on request might be the best solution, but I'd like to hear what ideas people have for managing this. For bonus points, I'm also curious about solutions for loading images on-demand server-side as well.

• Merging .net object graph

  - by Tiju John

  Hi guys, has anyone come across any scenario wherein you needed to merge one object with another object of same type, merging the complete object graph. for e.g. If i have a person object and one person object is having first name and other the last name, some way to merge both the objects into a single object. public class Person { public Int32 Id { get; set; } public string FirstName { get; set; } public string LastName { get; set; } } public class MyClass { //both instances refer to the same person, probably coming from different sources Person obj1 = new Person(); obj1.Id=1; obj1.FirstName = "Tiju"; Person obj2 = new Person(); ojb2.Id=1; obj2.LastName = "John"; //some way of merging both the object obj1.MergeObject(obj2); //?? //obj1.Id // = 1 //obj1.FirstName // = "Tiju" //obj1.LastName // = "John" } I had come across such type of requirement and I wrote an extension method to do the same. public static class ExtensionMethods { private const string Key = "Id"; public static IList MergeList(this IList source, IList target) { Dictionary itemData = new Dictionary(); //fill the dictionary for existing list string temp = null; foreach (object item in source) { temp = GetKeyOfRecord(item); if (!String.IsNullOrEmpty(temp)) itemData[temp] = item; } //if the same id exists, merge the object, otherwise add to the existing list. foreach (object item in target) { temp = GetKeyOfRecord(item); if (!String.IsNullOrEmpty(temp) && itemData.ContainsKey(temp)) itemData[temp].MergeObject(item); else source.Add(item); } return source; } private static string GetKeyOfRecord(object o) { string keyValue = null; Type pointType = o.GetType(); if (pointType != null) foreach (PropertyInfo propertyItem in pointType.GetProperties()) { if (propertyItem.Name == Key) { keyValue = (string)propertyItem.GetValue(o, null); } } return keyValue; } public static object MergeObject(this object source, object target) { if (source != null && target != null) { Type typeSource = source.GetType(); Type typeTarget = target.GetType(); //if both types are same, try to merge if (typeSource != null && typeTarget != null && typeSource.FullName == typeTarget.FullName) if (typeSource.IsClass && !typeSource.Namespace.Equals("System", StringComparison.InvariantCulture)) { PropertyInfo[] propertyList = typeSource.GetProperties(); for (int index = 0; index < propertyList.Length; index++) { Type tempPropertySourceValueType = null; object tempPropertySourceValue = null; Type tempPropertyTargetValueType = null; object tempPropertyTargetValue = null; //get rid of indexers if (propertyList[index].GetIndexParameters().Length == 0) { tempPropertySourceValue = propertyList[index].GetValue(source, null); tempPropertyTargetValue = propertyList[index].GetValue(target, null); } if (tempPropertySourceValue != null) tempPropertySourceValueType = tempPropertySourceValue.GetType(); if (tempPropertyTargetValue != null) tempPropertyTargetValueType = tempPropertyTargetValue.GetType(); //if the property is a list IList ilistSource = tempPropertySourceValue as IList; IList ilistTarget = tempPropertyTargetValue as IList; if (ilistSource != null || ilistTarget != null) { if (ilistSource != null) ilistSource.MergeList(ilistTarget); else propertyList[index].SetValue(source, ilistTarget, null); } //if the property is a Dto else if (tempPropertySourceValue != null || tempPropertyTargetValue != null) { if (tempPropertySourceValue != null) tempPropertySourceValue.MergeObject(tempPropertyTargetValue); else propertyList[index].SetValue(source, tempPropertyTargetValue, null); } } } } return source; } } However, this works when the source property is null, if target has it, it will copy that to source. IT can still be improved to merge when inconsistencies are there e.g. if FirstName="Tiju" and FirstName="John" Any commments appreciated. Thanks TJ

• Application Demos in UPK

  - by [email protected]

  Over the years, User Productivity Kit has expanded to include solutions to many project challenges. As of UPK 3.6.1, solutions are provided for pre and post application go-live learning, application testing, system documentation, presentation output, and more. New in UPK 3.6.1 are additional features that can be used effectively for application demo purposes. This can come in handy when you need to do a demo but don't want to show or can't show the live application. Maybe you're doing a presentation for a group of project stakeholders and want to focus on the business workflow implemented by the application rather than the mechanics of using it. Or possibly, you need to show the application but you're disconnected from any network preventing you from running the live application. In any of these cases, a presentation aid that represents the live application is what's needed. Previous versions of the UPK topic player would allow you to do this but would always show those UPK user interface elements that help a user learn the application. When you're presenting the narrative live, the UPK bubbles can be a distraction. UPK 3.6.1 provides some new features that allow you to control whether the bubbles display. There are two ways to hide bubbles in a topic. The first is a topic property that allows you to control bubbles across the entire topic. There are 3 settings for the Show Bubbles topic property. The default setting is Use frame settings which allows you to control whether bubbles display on a frame by frame basis. When you choose Always, the bubbles will always display regardless of the frame setting. The final choice is Never. Choosing Never will hide every bubble in your topic with one setting change. As with Always, choosing Never will ignore the frame setting. The second way to control the bubbles is at the frame level. First ensure that the topic's Show Bubbles property is set to Use frame settings. Navigate to the frame on which you want to turn off the bubble and click the Display bubble for this frame button to turn off the bubble. When you play the topic, the bubble will no longer be displayed. Depending on your needs, you might also use another longstanding UPK feature that allows you to control whether the action area displays on a frame. Just click the Action area on/off button to toggle its display. I've found the frame properties to be useful beyond creating presentation aids. When creating "See It!" only topics for more advanced users, I may hide the bubbles on some of the more straightforward frames. For example, if I have a form where one needs to fill out an address, I may display the first bubble in the sequence and explain what the subsequent steps are doing. I then hide bubbles on the remaining frames which are the more mechanical steps of entering the address. We'd like to hear your thoughts on this new UPK feature. Use the comments below to tell us how you've used it. John Zaums Senior Director, Product Development Oracle User Productivity Kit

• Why Your ERP System Isn't Ready for the Next Evolution of the Enterprise

  - by [email protected]

  By ken.pulverman on March 24, 2010 8:51 AM ERP has been the backbone of enterprise software. The data held in your ERP system is core of most companies. Efficiencies gained through the accounting and resource allocation through ERP software have literally saved companies trillions of dollars. Not only does everything seem to be fine with your ERP system, you haven't had to touch it in years. Why aren't you ready for what comes next? Well judging by the growth rates in the space (Oracle posted only a 3% growth rate, while SAP showed a 12% decline) there hasn't been much modernization going on, just a little replacement activity. If you are like most companies, your ERP system is connected to a proprietary middleware solution that only effectively talks with a handful of other systems you might have acquired from the same vendor. Connecting your legacy system through proprietary middleware is expensive and brittle and if you are like most companies, you were only willing to pay an SI so much before you said "enough." So your ERP is working. It's humming along. You might not be able to get Order to Promise information when you take orders in your call center, but there are work arounds that work just fine. So what's the problem? The problem is that you built your business around your ERP core, and now there is such pressure to innovate your business processes to keep up that you need a whole new slew of modern apps and you need ERP data to be accessible from everywhere. Every time you change a sales territory or a comp plan or change a benefits provider your ERP system, literally the economic brain of your business, needs to know what's going on. And this giant need to access and provide information to your ERP is only growing. What makes matters even more challenging is that apps today come in every flavor under the Sun™. SaaS, cloud, managed, hybrid, outsourced, composite....and they all have different integration protocols. The only easy way to get ahead of all this is to modernize the way you connect and run your applications. Unlike the middleware solutions of yesteryear, modern middleware is effectively the operating system of the enterprise. In the same way that you rely on Apple, Microsoft, and Google to find a video driver for your 23" monitor or to ensure that Word or Keynote runs, modern middleware takes care of intra-application connectivity and process execution. It effectively allows you to take ERP out of the middle while ensuring connectivity to your vital data for anything you want to do. The diagram below reflects that change. In this model, the hegemony of ERP is over. It too has to become a stealthy modern app to help you quickly adapt to business changes while managing vital information. And through modern middleware it will connect to everything. So yes ERP as we've know it is dead, but long live ERP as a connected application member of the modern enterprise. I want to Thank Andrew Zoldan, Group Vice President Oracle Manufacturing Industries Business Unit for introducing me to how some of his biggest customers have benefited by modernizing their applications infrastructure and making ERP a connected application. by John Burke, Group Vice President, Applications Business Unit

• How to count the most recent value based on multiple criteria?

  - by Andrew

  I keep a log of phone calls like the following where the F column is LVM = Left Voice Mail, U = Unsuccessful, S = Successful. A1 1 B1 Smith C1 John D1 11/21/2012 E1 8:00 AM F1 LVM A2 2 B2 Smith C2 John D2 11/22/2012 E1 8:15 AM F2 U A3 3 B3 Harvey C3 Luke D3 11/22/2012 E1 8:30 AM F3 S A4 4 B4 Smith C4 John D4 11/22/2012 E1 9:00 AM F4 S A5 5 B5 Smith C5 John D5 11/23/2012 E5 8:00 AM F5 LVM This is a small sample. I actually have over 700 entries. In my line of work, it is important to know how many unsuccessful (LVM or U) calls I have made since the last Successful one (S). Since values in the F column can repeat, I need to take into consideration both the B and C column. Also, since I can make a successful call with a client and then be trying to contact them again, I need to be able to count from the last successful call. My G column is completely open which is where I would like to put a running total for each client (G5 would = 1 ideally while G4 = 0, G3 = 0, G2 = 2, G1 = 1 but I want these values calculated automatically so that I do not have scroll through 700 names).

• OpenLDAP Authentication UID vs CN issues

  - by user145457

  I'm having trouble authenticating services using uid for authentication, which I thought was the standard method for authentication on the user. So basically, my users are added in ldap like this: # jsmith, Users, example.com dn: uid=jsmith,ou=Users,dc=example,dc=com uidNumber: 10003 loginShell: /bin/bash sn: Smith mail: [email protected] homeDirectory: /home/jsmith displayName: John Smith givenName: John uid: jsmith gecos: John Smith gidNumber: 10000 cn: John Smith title: System Administrator But when I try to authenticate using typical webapps or services like this: jsmith password I get: ldapsearch -x -h ldap.example.com -D "cn=jsmith,ou=Users,dc=example,dc=com" -W -b "dc=example,dc=com" Enter LDAP Password: ldap_bind: Invalid credentials (49) But if I use: ldapsearch -x -h ldap.example.com -D "uid=jsmith,ou=Users,dc=example,dc=com" -W -b "dc=example,dc=com" It works. HOWEVER...most webapps and authentication methods seem to use another method. So on a webapp I'm using, unless I specify the user as: uid=smith,ou=users,dc=example,dc=com Nothing works. In the webapp I just need users to put: jsmith in the user field. Keep in mind my ldap is using the "new" cn=config method of storing settings. So if someone has an obvious ldif I'm missing please provide. Let me know if you need further info. This is openldap on ubuntu 12.04. Thanks, Dave

• How to Programmatically Split Data Using VBA Using Specific Logic

  - by Charlene

  This is an addition to my previous post here. The code that was previously supplied to me worked like a charm, but I am having issues modifying it adding some additional logic. I am creating a macro in VBA to do the following. I have raw order data that I need to transform based on some logic. Raw Data: order-id product-num date buyer-name prod-name qty-purc sales-tax freight order-st 0000000000-00 10000000000000 5/29/2014 John Doe Product 0 1 1.00 1.50 GA 0000000000-00 10000000000001 5/29/2014 John Doe Product 1 2 1.00 1.50 GA 0000000000-00 10000000000002 5/29/2014 John Doe Product 2 1 1.00 2.00 GA 0000000000-01 10000000000002 5/30/2014 Jane Doe Product 2 1 0.00 0.00 PA 0000000000-01 10000000000003 5/30/2014 Jane Doe Product 3 1 0.00 0.00 PA Desired Outcome: HDR 0000000000-00 John Doe 5/29/2014 CHG Tax 3.00 CHG Freight 5.00 ITM 10000000000000 Product 0 1 ITM 10000000000001 Product 1 2 ITM 10000000000002 Product 2 1 HDR 0000000000-01 Jane Doe 5/30/2014 ITM 10000000000002 Product 2 1 ITM 10000000000003 Product 3 1 The "CHG" rows are created based on the following logic; if the order-st is CA or GA, add the total of sales-tax and freight for each of the rows with the same order-id. If the order-st is NOT CA or GA, no CHG rows should be created. Any help would be appreciated - let me know if I left any details out!

• Excel 2007 pivot table does not aggregate properly

  - by Patrick

  I am using a an excel pivot table to summarize some data and just found a problem. The problem deals with how aggregate values are calculated. Let's say I have a table of data with three columns: Name, Date, Value. If I create a table where Name and then Date are used as Row Labels and Value is the aggregate value, ie Average. The pivot table will look something like this: +John .3450 5/14/2010 1.234 5/15/2010 3.450 5/16/2010 -3.25 What I think should be happening here is that the values for each date are averaged and then those values are averaged to come up with the value in the same row as the Name, John. But that is not what it does. It takes the average for each date, which it shows across from the date, but then instead of taking the average of those numbers, it actually uses the raw data and computes the average for all of John's values. It should show the average of the daily averages to correspond with the tree hierarchy, but instead just shows me the average for all of John's values. It essential will only aggregate at one level, but visually creates sub levels that it is not using. Does anyone know how to change this or understand by what logic this makes sense? Why would I create any sub groupings if I cannot compute aggregates on them?

• How to Programmatically Split and Manipulate Rows of Data From Excel

  - by Charlene

  I am hoping one of you will be able to help get me started on this issue. I need to create some sort of macro or VBA code to split and manipulate rows of data in Excel. For this example, we have 5 rows of data. The first 3 rows are item information for Order # 0000000000-00 and the last 2 rows are item information for order # 0000000000-01. I need one row ("HDR") for each order number, and one row ("ITM") for each product per order. I have included an example below showing the data I will receive and the desired outcome. Raw Data: order-id product-num date buyer-name product-name quantity-purchased 0000000000-00 10000000000000 5/29/2014 John Doe Product 0 1 0000000000-00 10000000000001 5/29/2014 John Doe Product 1 2 0000000000-00 10000000000002 5/29/2014 John Doe Product 2 1 0000000000-01 10000000000002 5/30/2014 Jane Doe Product 2 1 0000000000-01 10000000000003 5/30/2014 Jane Doe Product 3 1 Desired Outcome: HDR 0000000000-00 John Doe 5/29/2014 ITM 10000000000000 Product 0 1 ITM 10000000000001 Product 1 2 ITM 10000000000002 Product 2 1 HDR 0000000000-01 Jane Doe 5/30/2014 ITM 10000000000002 Product 2 1 ITM 10000000000003 Product 3 1 Any and all help would be much appreciated!!!

• Excel 2007 - Adding line breaks in a cell and no line over 50 characters

  - by Richard Drew

  I have notes stored in an excel cell. I add line breaks and dates every time I add a new note. I need to copy this to another program, but it has a line limit of 50 characters. I want a line break for each new date and for when each date's comment goes over 50 characters. I'm able to do one or the other, but I can't figure out how to do both. I'd prefer words not to be split up, but at this point I don't care. Below is some sample input. If needed for a SUBSTITUTE or REPLACE function, I could add a ~ before each date in my input as a delimiter. Sample Input: 07/03 - FU on query. Copies and history included. CC to Jane Doe and John Public 06/29 - Cust claiming not to have these and wrong PO on query form. Responded with inv sent dates and locations, correct PO values, and copies. 06/27 - New ticket opened using query form 06/12 - Opened ticket with helpdesk asking status 05/21 - Copy submitted to [email protected] 05/14 - Copy sent to John Public and [email protected] Ideal Output: 07/03 - FU on query. Copies and history included. CC to Jane Doe and John Public 06/29 - Cust claiming not to have these and wrong PO on query form. Responded with inv sent dates an d locations, correct PO values, and copies. 06/27 - New ticket opened using query form 06/12 - Opened ticket with helpdesk asking status 05/21 - Copy submitted to [email protected] om 05/14 - Copy sent to John Public and email@custome r.com

• How to grant read/write to specific user in any existent or future subdirectory of a given directory? [migrated]

  - by Samuel Rossille

  I'm a complete newbie in system administration and I'm doing this as a hobby. I host my own git repository on a VPS. Let's say my user is john. I'm using the ssh protocol to access my git repository, so my url is something like ssh://[email protected]/path/to/git/myrepo/. Root is the owner of everything that's under /path/to/git I'm attempting to give read/write access to john to everything which is under /path/to/git/myrepo I've tried both chmod and setfacl to control access, but both fail the same way: they apply rights recursively (with the right options) to all the current existing subdirectories of /path/to/git/myrepo, but as soon as a new directory is created, my user can not write in the new directory. I know that there are hooks in git that would allow me to reapply the rights after each commit, but I'm starting to think that i'm going the wrong way because this seems too complicated for a very basic purpose. Q: How should I setup my right to give rw access to john to anything under /path/to/git/myrepo and make it resilient to tree structure change ? Q2: If I should take a step back change the general approach, please tell me.

• C# Linq List Contains Similar Elements

  - by John Peters

  Hi All, I am looking for linq query to see if there exists a similar object I have an object graph as follows Cart myCart = new Cart { List<CartProduct> myCartProduct = new List<CartProduct> { CartProduct cartProduct1 = new CartProduct { List<CartProductAttribute> a = new List<CartProductAttribute> { CartProductAttribute cpa1 = new CartProductAttribute{ title="red" }, CartProductAttribute cpa2 = new CartProductAttribute{ title="small" } } } CartProduct cartProduct2 = new CartProduct { List<CartProductAttribute> d = new List<CartProductAttribute> { CartProductAttribute cpa3 = new CartProductAttribute{ title="john" }, CartProductAttribute cpa4 = new CartProductAttribute{ title="mary" } } } } } I would like to get from the Cart = a CartProduct that has the exact same CartProductAttribute title values as a CartProduct that I need to compare. No more and no less. E.G. I need to find a similar CartProduct that has a CartProductAttribute with title="red" and a cartProductAttribute with title="small" in myCart (eg 'cartProduct1' in the example) CartProduct cartProductToCompare = new CartProduct { List<CartProductAttribute> cartProductToCompareAttributes = new List<CartProductAttribute> { CartProductAttribute cpa5 = new CartProductAttribute{ title="red" }, CartProductAttribute cpa6 = new CartProductAttribute{ title="small" } } } So from object graph myCart cartProduct1 cpa1 (title=red) cpa2 (title=small) cartProduct2 cpa3 (title=john) cpa4 (title=mary) Linq query looking for cartProductToCompare cpa5 (title=red) cpa6 (title=small) Should find cartProduct1 Hope all this makes sense...

• Informix, NHibernate, TransactionScope interaction difficulties

  - by John Prideaux

  I have a small program that is trying to wrap an NHibernate insert into an Informix database in a TransactionScope object using the Informix .NET Provider. I am getting the error specified below. The code without the TransactionScope object works -- including when the insert is wrapped in an NHibernate session transaction. Any ideas on what the problem is? BTW, without the EnterpriseServicesInterop, the Informix .NET Provider will not participate in a TransactionScope transaction (verified without NHibernate involved). Code Snippet: public static void TestTScope() { Employee johnp = new Employee { name = "John Prideaux" }; using (TransactionScope tscope = new TransactionScope( TransactionScopeOption.Required, new TransactionOptions() { Timeout = new TimeSpan(0, 1, 0), IsolationLevel = IsolationLevel.ReadCommitted }, EnterpriseServicesInteropOption.Full)) { using (ISession session = OpenSession()) { session.Save(johnp); Console.WriteLine("Saved John to the database"); } } Console.WriteLine("Transaction should be rolled back"); } static ISession OpenSession() { if (factory == null) { Configuration c = new Configuration(); c.AddAssembly(Assembly.GetCallingAssembly()); factory = c.BuildSessionFactory(); } return factory.OpenSession(); } static ISessionFactory factory; Stack Trace: NHibernate.ADOException was unhandled Message="Could not close IBM.Data.Informix.IfxConnection connection" Source="NHibernate" StackTrace: at NHibernate.Connection.ConnectionProvider.CloseConnection(IDbConnection conn) at NHibernate.Connection.DriverConnectionProvider.CloseConnection(IDbConnection conn) at NHibernate.Tool.hbm2ddl.SuppliedConnectionProviderConnectionHelper.Release() at NHibernate.Tool.hbm2ddl.SchemaMetadataUpdater.GetReservedWords(Dialect dialect, IConnectionHelper connectionHelper) at NHibernate.Tool.hbm2ddl.SchemaMetadataUpdater.Update(ISessionFactory sessionFactory) at NHibernate.Impl.SessionFactoryImpl..ctor(Configuration cfg, IMapping mapping, Settings settings, EventListeners listeners) at NHibernate.Cfg.Configuration.BuildSessionFactory() at HelloNHibernate.Employee.OpenSession() in D:\Development\ScratchProject\HelloNHibernate\Employee.cs:line 73 at HelloNHibernate.Employee.TestTScope() in D:\Development\ScratchProject\HelloNHibernate\Employee.cs:line 53 at HelloNHibernate.Program.Main(String[] args) in D:\Development\ScratchProject\HelloNHibernate\Program.cs:line 19 at System.AppDomain._nExecuteAssembly(Assembly assembly, String[] args) at System.AppDomain.ExecuteAssembly(String assemblyFile, Evidence assemblySecurity, String[] args) at Microsoft.VisualStudio.HostingProcess.HostProc.RunUsersAssembly() at System.Threading.ThreadHelper.ThreadStart_Context(Object state) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Threading.ThreadHelper.ThreadStart() InnerException: IBM.Data.Informix.IfxException Message="ERROR - no error information available" Source="IBM.Data.Informix" ErrorCode=-2147467259 StackTrace: at IBM.Data.Informix.IfxConnection.HandleError(IntPtr hHandle, SQL_HANDLE hType, RETCODE retcode) at IBM.Data.Informix.IfxConnection.DisposeClose() at IBM.Data.Informix.IfxConnection.Close() at NHibernate.Connection.ConnectionProvider.CloseConnection(IDbConnection conn) InnerException:

• Print to File in Black and White (not in greyscale)

  - by user2413

  Hi all, I have these pdf files of c++code and they are colored which would be cool, except that the network printer here is b&w and the printed out codes come in various shades of pale grey which makes them essentially unreadable (specially the comments). I would like everything (text, codes, commands,...) to be printed in the same (black) color. i've tried fuddling with the printer's properties, but the closest thing i see is the 'level of grey' tab, and there i have the choice between 'enhanced' and 'normal' (and it doesn't make a difference in my case). i've tried 'print to file', but i don't see any options there to print to b&w, I've tried installing the 'generic cups printer', but again no options to print to b&w. any idea ? (i'm on 10.10)

• User Productivity Kit - Powerful Packages (Part 2)

  - by [email protected]

  In my first post on packages I described what a package is and how it can be used. I also started explaining some of the considerations that should be taken into account when determining how to arrange your packages. The first is when the files are interrelated and depend on one another such as an HTML file and it's graphics. A second consideration is how the files are used in your outlines. Let's say you're using a dozen Word doc files. You could place them all in a single package or put each Word doc file in a separate package but what's the right thing to do? There are several factors that will influence your decision. To understand the first, let me explain a function of UPK publishing. Take an outline in UPK that has an attachment (concept, frame link, or hyperlink) that points to a file in a package. When you publish this outline, the publishing engine will determine that there is a link to a file in the package and copy the contents of the package to the publishing destination directory. This is done to ensure that any interrelated files are kept together. For the situation where you have an HTML file with links to number of graphics files, this is a good thing. If, however, the package has a dozen unrelated Word doc files and you link to only one of them, all dozen Word documents will be copied to the publishing destination directory.  Whether or not this is a good thing is dependent on two things. First, are all of the files in the package used in the outline that you're publishing? Take an outline that includes links to all of the Word documents in that dozen document package I described earlier. For this situation, you may choose to keep all the files in a single package for convenience. A second consideration is how your organization leverages reuse in UPK. In this context, I'm referring to the link style of reuse such as when you link to the same topic from multiple UPK outlines and changes to the topic appear in both places. Take an example where you have the earlier mentioned dozen Word document package and an outline with a dozen topics in it. Each topic has an attachment pointing to one of the Word documents in the package (frame link, concept, etc.) If you're only publishing this outline, the single package probably works fine but what if you're reusing one of these topics in another outline? As I explained earlier, linking to one file in the package will result in all files in the package being copied to your published output. In this example, linking to one topic in the first outline will result in all dozen Word documents being copied to the published output. This may result in files in the output that you don't want there for business or size reasons. This is a situation in which you should consider placing each of the Word documents in it's own separate package. With each document in it's own package, that link to a single document will result in only that single package and single Word document being copied to the published output. In my last post I had described that packages are documents in the UPK library. When using the multi-user version of the UPK Developer you can leverage standard library capabilities for managing the files in these packages during the development process - capabilities such as check in / check out, history, etc. When structuring your packages take into consideration how the authors are going to be adding, modifying and deleting files from the packages. A single package is a single document in the UPK library. Like any other document in the library, a single user can check out the package and edit it at a time. If you have a large number of files in a single package and these must be modified by many users, you need to consider whether this will cause problems as multiple users compete to update the same package. If the files don't depend on each other consider placing the files in separate packages to reduce contention. I hope you've enjoyed these two posts on how you can leverage the power of packages in your content. In summary, consider the following when structuring your packages: Is the asset a single, standalone file or a set of files that depend on each other? Will all the files always be used together in a single outline or may only some of the files be needed based on how the content is reused across multiple outlines? Will multiple developers need to update the files in a single package or should you break it into multiple packages to reduce contention when checking out the document? We'd like to hear from you on how you're using packages in your content. Please add your comments below! Thank you and I hope these two posts have given you additional insights into how to use packages in your content and structure them for efficient use.

• Live CD boot/installation problem, blank screen - 12.04

  - by traubi

  I'm trying to install ubuntu-12.04-desktop-amd64 from my usb stick. When booting from usb I instantly get a blank screen (with a grey box at the left bottom) I checked the live system with my laptop.works well except it also starts of with a black screen and a grey box at the bottom. I figure the Problem is my geforce gtx 570 since older versions of Ubuntu where only able to boot with xforcevesa and nomodeset. Unfortunately I can't change the boot parameters. I tried the alternate version for a text based install, but it has the same problem. If I press Esc in the alternate I get a message box with two buttons but no text. I would be happy for any advice on this matter
