Strange behaviour when simply adding strings in Lazarus - FreePascal

- by linkcharger

The program has several "encryption" algorithms. This one should blockwise reverse the input. "He|ll|o " becomes "o |ll|He" (block length of 2). I add two strings, in this case appending the result string to the current "block" string and making that the result. When I add the result first and then the block it works fine and gives me back the original string. But when i try to reverse the order it just gives me the the last "block". Several other functions that are used for "rotation" are above. //amount of blocks function amBl(i1:integer;i2:integer):integer; begin if (i1 mod i2) <> 0 then result := (i1 div i2) else result := (i1 div i2) - 1; end; //calculation of block length function calcBl(keyStr:string):integer; var i:integer; begin result := 0; for i := 1 to Length(keyStr) do begin result := (result + ord(keyStr[i])) mod 5; result := result + 2; end; end; //desperate try to add strings function append(s1,s2:string):string; begin insert(s2,s1,Length(s1)+1); result := s1; end; function rotation(inStr,keyStr:string):string; var //array of chars -> string block,temp:string; //position in block variable posB:integer; //block length and block count variable bl, bc:integer; //null character as placeholder n : ansiChar; begin //calculating block length 2..6 bl := calcBl(keyStr); setLength(block,bl); result := ''; temp := ''; {n := #00;} for bc := 0 to amBl(Length(inStr),bl) do begin //filling block with chars starting from back of virtual block (in inStr) for posB := 1 to bl do begin block[posB] := inStr[bc * bl + posB]; {if inStr[bc * bl + posB] = ' ' then block[posB] := n;} end; //adding the block in front of the existing result string temp := result; result := block + temp; //result := append(block,temp); //result := concat(block,temp); end; end; (full code http://pastebin.com/6Uarerhk) After all the loops "result" has the right value, but in the last step (between "result := block + temp" and the "end;" of the function) "block" replaces the content of "result" with itself completely, it doesn't add result at the end anymore. And as you can see I even used a temp variable to try to work around that.. doesnt change anything though.

No Method Error in Ruby

- by JayG

Hi, I currently have a Rails Apps that lets users drag and drop certain elements of the webpage and updates the application based on the users choice. This is done with the help of the Rails helpers and AJAX. However I keep running into a "NoMethodError" in Ruby. NoMethodError in ProjectsController#member_change undefined method `symbolize_keys' for nil:NilClass Here is the method that is being called.

VBScript Multiple folder check if then statement

I had this working before just fine with the exception of getting an error if one of the folders was not there, so I tried to fix it.

How does java.util.Collections.contains() perform faster than a linear search?

- by The111

I've been fooling around with a bunch of different ways of searching collections, collections of collections, etc. Doing lots of stupid little tests to verify my understanding. Here is one which boggles me (source code further below). In short, I am generating N random integers and adding them to a list. The list is NOT sorted. I then use Collections.contains() to look for a value in the list. I intentionally look for a value that I know won't be there, because I want to ensure that the entire list space is probed. I time this search. I then do another linear search manually, iterating through each element of the list and checking if it matches my target. I also time this search. On average, the second search takes 33% longer than the first one. By my logic, the first search must also be linear, because the list is unsorted. The only possibility I could think of (which I immediately discard) is that Java is making a sorted copy of my list just for the search, but (1) I did not authorize that usage of memory space and (2) I would think that would result in MUCH more significant time savings with such a large N. So if both searches are linear, they should both take the same amount of time. Somehow the Collections class has optimized this search, but I can't figure out how. So... what am I missing? import java.util.*; public class ListSearch { public static void main(String[] args) { int N = 10000000; // number of ints to add to the list int high = 100; // upper limit for random int generation List<Integer> ints; int target = -1; // target will not be found, forces search of entire list space long start; long end; ints = new ArrayList<Integer>(); start = System.currentTimeMillis(); System.out.print("Generating new list... "); for (int i = 0; i < N; i++) { ints.add(((int) (Math.random() * high)) + 1); } end = System.currentTimeMillis(); System.out.println("took " + (end-start) + "ms."); start = System.currentTimeMillis(); System.out.print("Searching list for target (method 1)... "); if (ints.contains(target)) { // nothing } end = System.currentTimeMillis(); System.out.println(" Took " + (end-start) + "ms."); System.out.println(); ints = new ArrayList<Integer>(); start = System.currentTimeMillis(); System.out.print("Generating new list... "); for (int i = 0; i < N; i++) { ints.add(((int) (Math.random() * high)) + 1); } end = System.currentTimeMillis(); System.out.println("took " + (end-start) + "ms."); start = System.currentTimeMillis(); System.out.print("Searching list for target (method 2)... "); for (Integer i : ints) { // nothing } end = System.currentTimeMillis(); System.out.println(" Took " + (end-start) + "ms."); } }

Parallelism in .NET – Introduction

- by Reed

Parallel programming is something that every professional developer should understand, but is rarely discussed or taught in detail in a formal manner. Software users are no longer content with applications that lock up the user interface regularly, or take large amounts of time to process data unnecessarily. Modern development requires the use of parallelism. There is no longer any excuses for us as developers. Learning to write parallel software is challenging. It requires more than reading that one chapter on parallelism in our programming language book of choice… Today’s systems are no longer getting faster with each generation; in many cases, newer computers are actually slower than previous generation systems. Modern hardware is shifting towards conservation of power, with processing scalability coming from having multiple computer cores, not faster and faster CPUs. Our CPU frequencies no longer double on a regular basis, but Moore’s Law is still holding strong. Now, however, instead of scaling transistors in order to make processors faster, hardware manufacturers are scaling the transistors in order to add more discrete hardware processing threads to the system. This changes how we should think about software. In order to take advantage of modern systems, we need to redesign and rewrite our algorithms to work in parallel. As with any design domain, it helps tremendously to have a common language, as well as a common set of patterns and tools. For .NET developers, this is an exciting time for parallel programming. Version 4 of the .NET Framework is adding the Task Parallel Library. This has been back-ported to .NET 3.5sp1 as part of the Reactive Extensions for .NET, and is available for use today in both .NET 3.5 and .NET 4.0 beta. In order to fully utilize the Task Parallel Library and parallelism, both in .NET 4 and previous versions, we need to understand the proper terminology. For this series, I will provide an introduction to some of the basic concepts in parallelism, and relate them to the tools available in .NET.

Silverlight Recruiting Application Part 6 - Adding an Interview Scheduling Module/View

Between the last post and this one I went ahead and carried the ideas for the Jobs module and view into the Applicants module and view- they're both doing more or less the same thing, except with different objects being at their core. Made for an easy cut-and-paste operation with a few items being switched from one to another. Now that we have the ability to add postings and applicants, wouldn't it be nice if we could schedule an interview? Of course it would! Scheduling Module I think you get the drift from previous posts that these project structures start looking somewhat similar. The interview scheduling module is no different than the rest- it gets a SchedulingModule.cs file at the root that inherits from IModule, and there is a single SchedulerView.xsml and SchedulerViewModel.cs setup for our V+VM. We have one unique concern as we enter into this- RadScheduler deals with AppointmentsSource, not ItemsSource, so there are some special considerations to take into account when planning this module. First, I need something which inherits from AppointmentBase. This is the core of the RadScheduler appointment, and if you are planning to do any form of custom appointment, you'll want it to inherit from this. Then you can add-on functionality as needed. Here is my addition to the mix, the InterviewAppointment: 01.public class InterviewAppointment : AppointmentBase 02.{ 03. private int _applicantID; 04. public int ApplicantID 05. { 06. get { return this._applicantID; } 07. set 08. { 09. if (_applicantID != value) 10. { 11. _applicantID = value; 12. OnPropertyChanged("ApplicantID"); 13. } 14. } 15. } 16. 17. private int _postingID; 18. public int PostingID 19. { 20. get { return _postingID; } 21. set 22. { 23. if (_postingID != value) 24. { 25. _postingID = value; 26. OnPropertyChanged("PostingID"); 27. } 28. } 29. } 30. 31. private string _body; 32. public string Body 33. { 34. get { return _body; } 35. set 36. { 37. if (_body != value) 38. { 39. _body = value; 40. OnPropertyChanged("Body"); 41. } 42. } 43. } 44. 45. private int _interviewID; 46. public int InterviewID 47. { 48. get { return _interviewID; } 49. set 50. { 51. if (_interviewID != value) 52. { 53. _interviewID = value; 54. OnPropertyChanged("InterviewID"); 55. } 56. } 57. } 58. 59. public override IAppointment Copy() 60. { 61. IAppointment appointment = new InterviewAppointment(); 62. appointment.CopyFrom(this); 63. return appointment; 64. } 65. 66. public override void CopyFrom(IAppointment other) 67. { 68. base.CopyFrom(other); 69. var appointment = other as InterviewAppointment; 70. if (appointment != null) 71. { 72. ApplicantID = appointment.ApplicantID; 73. PostingID = appointment.PostingID; 74. Body = appointment.Body; 75. InterviewID = appointment.InterviewID; 76. } 77. } 78.} Nothing too exciting going on here, we just make sure that our custom fields are persisted (specifically set in CopyFrom at the bottom) and notifications are fired- otherwise this ends up exactly like the standard appointment as far as interactions, etc. But if we've got custom appointment items... that also means we need to customize what our appointment dialog window will look like. Customizing the Edit Appointment Dialog This initially sounds a lot more intimidating than it really is. The first step here depends on what you're dealing with for theming, but for ease of everything I went ahead and extracted my templates in Blend for RadScheduler so I could modify it as I pleased. For the faint of heart, the RadScheduler template is a few thousand lines of goodness since there are some very complex things going on in that control. I've gone ahead and trimmed down the template parts I don't need as much as possible, so what is left is all that is relevant to the Edit Appointment Dialog. Here's the resulting Xaml, with line numbers, so I can explain further: 001.<UserControl.Resources> 002.  003. <helpers:DataContextProxy x:Key="DataContextProxy" /> 004. 005. <telerik:Windows7Theme x:Key="Theme" /> 006. <SolidColorBrush x:Key="DialogWindowBackground" 007.

Where we start getting into the dialog in question is line 132, but line 407 is where things start getting interesting. The ItemsSource is pointing at a list that exists in my ViewModel (or code-behind, if it is used as a DataContext), the SelectedValue is the item I am actually binding from the applicant (note the TwoWay binding), and SelectedValuePath and DisplayMemberPath ensure the proper applicant is being displayed from the collection. You will also see similar starting on line 420 where I do the same for the Jobs we'll be displaying. Just to wrap-up the Xaml, here's the RadScheduler declaraction that ties this all together and will be the main focus of our view: 01.<telerikScheduler:RadScheduler x:Name="xJobsScheduler" 02.

And for those of you who remember the jobs post, those command:s in the Xaml are pointing to attached behavior commands that reproduce the respective events. This becomes very handy when we're setting up the code-behind version. ;) ViewModel I've been liking this approach so far, so I'm going to put the entire ViewModel here and then go into the lines of interest.

I know this is something which will be fixed down the line for using RadScheduler, simplifying this process, but with WCF RIA changing as it does I wanted to ensure functionality would remain consistent as I continued development on this application. So, I do a little bit of duplication, but for the greater good. This all takes place starting on line 79, so for every entity that comes back we add it to the collection that is bound to RadScheduler. Otherwise, the DelegateCommands that you see correspond directly to the events they are named after. In each case, rather than sending over the full event arguments, I just send in the appointment in question (coming through as the object obj in all cases) so I can add (line 91), edit (line 119), and delete appointments (line 142) like normal. This just ensures they get updated back to my database. Also, the one bit of code you won't see is for the Appointment Creating (line 110) event- that is because in the command I've created I simply make the replacement I need to: 1.void element_AppointmentCreating(object sender, AppointmentCreatingEventArgs e) 2.{ 3. e.NewAppointment = new InterviewAppointment(); 4. base.ExecuteCommand(); 5.} And the ViewModel is none the wiser, the appointments just work as far as it is concerned since as they are created they become InterviewAppointments. End result? I've customized my EditAppointmentDialog as follows: And adding, editing, and deleting appointments works like a charm. I can even 'edit' by moving appointments around RadScheduler, so as they are dropped into a timeslot they perform their full edit routine and things get updated. And then, the Code-Behind Version Perhaps the thing I like the most about doing one then the other is I get to steal 90% or more of the code from the MVVM version. For example, the only real changes to the Code-Behind Xaml file exist in the control declaration, in which I use events instead of attached-behavior-event-commands: 01.<telerikScheduler:RadScheduler x:Name="xJobsScheduler" 02. Grid.Row="1" 03. Grid.Column="1" 04. Width="800" 05. MinWidth="600" 06. Height="500" 07. MinHeight="300" 08. EditAppointmentStyle="{StaticResource EditAppointmentStyle}" 09. AppointmentAdded="xJobsScheduler_AppointmentAdded" 10. AppointmentCreating="xJobsScheduler_AppointmentCreating" 11. AppointmentEdited="xJobsScheduler_AppointmentEdited" 12. AppointmentDeleted="xJobsScheduler_AppointmentDeleted"> 13.</telerikScheduler:RadScheduler> Easy, right? Otherwise, all the same styling in UserControl.Resources was re-used, right down to the DataContextProxy that lets us bind to a collection from our viewmodel (in this case, our code-behind) to use within the DataTemplate. The code conversion gets even easier, as I could literally copy and paste almost everything from the ViewModel to my Code-Behind, just a matter of pasting the right section into the right event. Here's the code-behind as proof: 001.public partial class SchedulingView : UserControl, INotifyPropertyChanged 002.{ 003. public RecruitingContext context; 004. 005. private QueryableCollectionView _jobsList; 006. public QueryableCollectionView JobsList 007. { 008. get { return this._jobsList; } 009. set 010. { 011. if (this._jobsList != value) 012. { 013. this._jobsList = value; 014. this.NotifyChanged("JobsList"); 015. } 016. } 017. } 018. 019. private QueryableCollectionView _applicantList; 020. public QueryableCollectionView ApplicantList 021. { 022. get { return _applicantList; } 023. set 024. { 025. if (_applicantList != value) 026. { 027. _applicantList = value; 028.

See on line 51 where I set the DataContext before the Loaded event? This is super important, as if you don't have this set before the usercontrol is loaded, the DataContextProxy has no context to use and your EditAppointmentDialog Job/Applicant dropdowns will be blank and empty. Trust me on this, took a little bit of debugging to figure out that by setting the DataContext post-loaded would only lead to disaster and frustration. Otherwise, the only other real difference is that instead of sending an ActionHistory item through an event to get added to the database and saved, I do those right in the callback from submitting. The Result Again, I only have to post one picture because these bad boys used nearly identical code for both the MVVM and the code-behind views, so our end result is... So what have we learned here today? One, for the most part this MVVM thing is somewhat easy. Yeah, you sometimes have to write a bunch of extra code, but with the help of a few useful snippits you can turn the process into a pretty streamlined little workflow. Heck, this story gets even easier as you can see in this blog post by Michael Washington- specifically run a find on 'InvokeCommandAction' and you'll see the section regarding the command on TreeView in Blend 4. Brilliant! MVVM never looked so sweet! Otherwise, it is business as usual with RadScheduler for Silverlight whichever path you're choosing for your development. Between now and the next post, I'll be cleaning up styles a bit (those RadComboBoxes are a little too close to my labels!) and adding some to the RowDetailsViews for Applicants and Jobs, so you can see all the info for an appointment in the dropdown tab view. Otherwise, we're about ready to call a wrap on this oneDid you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

Can't add Fedora 14 to grub.

- by Dananjaya

Today I installed Fedora 14 in a different partition in the same hard drive as Ubuntu. At the Fedora 14 installation, I chose not to install Boot-loader in the MBR, and instead chose to install it in the Fedora partition itself, which is according to my HD layout /sda3. After the Fedora 14 installation I booted in to Ubuntu and ran sudo update-grub but 'grub.cfg' fails to add Fedora 14 in to the OS list. Here is the output of boot-info script.

Silverlight Recruiting Application Part 6 - Adding an Interview Scheduling Module/View

Between the last post and this one I went ahead and carried the ideas for the Jobs module and view into the Applicants module and view- they're both doing more or less the same thing, except with different objects being at their core. Made for an easy cut-and-paste operation with a few items being switched from one to another. Now that we have the ability to add postings and applicants, wouldn't it be nice if we could schedule an interview? Of course it would! Scheduling Module I think you get the drift from previous posts that these project structures start looking somewhat similar. The interview scheduling module is no different than the rest- it gets a SchedulingModule.cs file at the root that inherits from IModule, and there is a single SchedulerView.xsml and SchedulerViewModel.cs setup for our V+VM. We have one unique concern as we enter into this- RadScheduler deals with AppointmentsSource, not ItemsSource, so there are some special considerations to take into account when planning this module. First, I need something which inherits from AppointmentBase. This is the core of the RadScheduler appointment, and if you are planning to do any form of custom appointment, you'll want it to inherit from this. Then you can add-on functionality as needed. Here is my addition to the mix, the InterviewAppointment: 01.public class InterviewAppointment : AppointmentBase 02.{ 03. private int _applicantID; 04. public int ApplicantID 05. { 06. get { return this._applicantID; } 07. set 08. { 09. if (_applicantID != value) 10. { 11. _applicantID = value; 12. OnPropertyChanged("ApplicantID"); 13. } 14. } 15. } 16. 17. private int _postingID; 18. public int PostingID 19. { 20. get { return _postingID; } 21. set 22. { 23. if (_postingID != value) 24. { 25. _postingID = value; 26. OnPropertyChanged("PostingID"); 27. } 28. } 29. } 30. 31. private string _body; 32. public string Body 33. { 34. get { return _body; } 35. set 36. { 37. if (_body != value) 38. { 39. _body = value; 40. OnPropertyChanged("Body"); 41. } 42. } 43. } 44. 45. private int _interviewID; 46. public int InterviewID 47. { 48. get { return _interviewID; } 49. set 50. { 51. if (_interviewID != value) 52. { 53. _interviewID = value; 54. OnPropertyChanged("InterviewID"); 55. } 56. } 57. } 58. 59. public override IAppointment Copy() 60. { 61. IAppointment appointment = new InterviewAppointment(); 62. appointment.CopyFrom(this); 63. return appointment; 64. } 65. 66. public override void CopyFrom(IAppointment other) 67. { 68. base.CopyFrom(other); 69. var appointment = other as InterviewAppointment; 70. if (appointment != null) 71. { 72. ApplicantID = appointment.ApplicantID; 73. PostingID = appointment.PostingID; 74. Body = appointment.Body; 75. InterviewID = appointment.InterviewID; 76. } 77. } 78.} Nothing too exciting going on here, we just make sure that our custom fields are persisted (specifically set in CopyFrom at the bottom) and notifications are fired- otherwise this ends up exactly like the standard appointment as far as interactions, etc. But if we've got custom appointment items... that also means we need to customize what our appointment dialog window will look like. Customizing the Edit Appointment Dialog This initially sounds a lot more intimidating than it really is. The first step here depends on what you're dealing with for theming, but for ease of everything I went ahead and extracted my templates in Blend for RadScheduler so I could modify it as I pleased. For the faint of heart, the RadScheduler template is a few thousand lines of goodness since there are some very complex things going on in that control. I've gone ahead and trimmed down the template parts I don't need as much as possible, so what is left is all that is relevant to the Edit Appointment Dialog. Here's the resulting Xaml, with line numbers, so I can explain further: 001.<UserControl.Resources> 002.  003. <helpers:DataContextProxy x:Key="DataContextProxy" /> 004. 005. <telerik:Windows7Theme x:Key="Theme" /> 006. <SolidColorBrush x:Key="DialogWindowBackground" 007.

Where we start getting into the dialog in question is line 132, but line 407 is where things start getting interesting. The ItemsSource is pointing at a list that exists in my ViewModel (or code-behind, if it is used as a DataContext), the SelectedValue is the item I am actually binding from the applicant (note the TwoWay binding), and SelectedValuePath and DisplayMemberPath ensure the proper applicant is being displayed from the collection. You will also see similar starting on line 420 where I do the same for the Jobs we'll be displaying. Just to wrap-up the Xaml, here's the RadScheduler declaraction that ties this all together and will be the main focus of our view: 01.<telerikScheduler:RadScheduler x:Name="xJobsScheduler" 02.

And for those of you who remember the jobs post, those command:s in the Xaml are pointing to attached behavior commands that reproduce the respective events. This becomes very handy when we're setting up the code-behind version. ;) ViewModel I've been liking this approach so far, so I'm going to put the entire ViewModel here and then go into the lines of interest.

I know this is something which will be fixed down the line for using RadScheduler, simplifying this process, but with WCF RIA changing as it does I wanted to ensure functionality would remain consistent as I continued development on this application. So, I do a little bit of duplication, but for the greater good. This all takes place starting on line 79, so for every entity that comes back we add it to the collection that is bound to RadScheduler. Otherwise, the DelegateCommands that you see correspond directly to the events they are named after. In each case, rather than sending over the full event arguments, I just send in the appointment in question (coming through as the object obj in all cases) so I can add (line 91), edit (line 119), and delete appointments (line 142) like normal. This just ensures they get updated back to my database. Also, the one bit of code you won't see is for the Appointment Creating (line 110) event- that is because in the command I've created I simply make the replacement I need to: 1.void element_AppointmentCreating(object sender, AppointmentCreatingEventArgs e) 2.{ 3. e.NewAppointment = new InterviewAppointment(); 4. base.ExecuteCommand(); 5.} And the ViewModel is none the wiser, the appointments just work as far as it is concerned since as they are created they become InterviewAppointments. End result? I've customized my EditAppointmentDialog as follows: And adding, editing, and deleting appointments works like a charm. I can even 'edit' by moving appointments around RadScheduler, so as they are dropped into a timeslot they perform their full edit routine and things get updated. And then, the Code-Behind Version Perhaps the thing I like the most about doing one then the other is I get to steal 90% or more of the code from the MVVM version. For example, the only real changes to the Code-Behind Xaml file exist in the control declaration, in which I use events instead of attached-behavior-event-commands: 01.<telerikScheduler:RadScheduler x:Name="xJobsScheduler" 02. Grid.Row="1" 03. Grid.Column="1" 04. Width="800" 05. MinWidth="600" 06. Height="500" 07. MinHeight="300" 08. EditAppointmentStyle="{StaticResource EditAppointmentStyle}" 09. AppointmentAdded="xJobsScheduler_AppointmentAdded" 10. AppointmentCreating="xJobsScheduler_AppointmentCreating" 11. AppointmentEdited="xJobsScheduler_AppointmentEdited" 12. AppointmentDeleted="xJobsScheduler_AppointmentDeleted"> 13.</telerikScheduler:RadScheduler> Easy, right? Otherwise, all the same styling in UserControl.Resources was re-used, right down to the DataContextProxy that lets us bind to a collection from our viewmodel (in this case, our code-behind) to use within the DataTemplate. The code conversion gets even easier, as I could literally copy and paste almost everything from the ViewModel to my Code-Behind, just a matter of pasting the right section into the right event. Here's the code-behind as proof: 001.public partial class SchedulingView : UserControl, INotifyPropertyChanged 002.{ 003. public RecruitingContext context; 004. 005. private QueryableCollectionView _jobsList; 006. public QueryableCollectionView JobsList 007. { 008. get { return this._jobsList; } 009. set 010. { 011. if (this._jobsList != value) 012. { 013. this._jobsList = value; 014. this.NotifyChanged("JobsList"); 015. } 016. } 017. } 018. 019. private QueryableCollectionView _applicantList; 020. public QueryableCollectionView ApplicantList 021. { 022. get { return _applicantList; } 023. set 024. { 025. if (_applicantList != value) 026. { 027. _applicantList = value; 028.

See on line 51 where I set the DataContext before the Loaded event? This is super important, as if you don't have this set before the usercontrol is loaded, the DataContextProxy has no context to use and your EditAppointmentDialog Job/Applicant dropdowns will be blank and empty. Trust me on this, took a little bit of debugging to figure out that by setting the DataContext post-loaded would only lead to disaster and frustration. Otherwise, the only other real difference is that instead of sending an ActionHistory item through an event to get added to the database and saved, I do those right in the callback from submitting. The Result Again, I only have to post one picture because these bad boys used nearly identical code for both the MVVM and the code-behind views, so our end result is... So what have we learned here today? One, for the most part this MVVM thing is somewhat easy. Yeah, you sometimes have to write a bunch of extra code, but with the help of a few useful snippits you can turn the process into a pretty streamlined little workflow. Heck, this story gets even easier as you can see in this blog post by Michael Washington- specifically run a find on 'InvokeCommandAction' and you'll see the section regarding the command on TreeView in Blend 4. Brilliant! MVVM never looked so sweet! Otherwise, it is business as usual with RadScheduler for Silverlight whichever path you're choosing for your development. Between now and the next post, I'll be cleaning up styles a bit (those RadComboBoxes are a little too close to my labels!) and adding some to the RowDetailsViews for Applicants and Jobs, so you can see all the info for an appointment in the dropdown tab view. Otherwise, we're about ready to call a wrap on this oneDid you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

Oracle VM Blade Cluster Reference Configuration

- by Ferhat Hatay

Today we are happy to announce the availability of the Oracle VM blade cluster reference configuration for Sun Blade 6000 modular systems. The new Oracle VM blade cluster reference configuration can help reduce the time to deploy virtual infrastructure by up to 98 percent when compared to multi-vendor configurations. Oracle's virtualization strategy is to simplify the deployment, management, and support of the enterprise stack from application to disk. The Oracle VM blade cluster reference configuration is a single-vendor solution that addresses every layer of the virtualization stack with Oracle hardware and software components. It enables quick and easy deployment of the virtualized infrastructure using components that have been tested together and are all supported together by one vendor — Oracle. All components listed in the reference configuration have been tested together by Oracle, reducing the need for customer testing and the time-consuming and complex effort of designing and deploying a stable configuration. Benefitting from pre-installed Oracle VM Server for x86 software on Oracle’s highly scalable and reliable Sun Blade servers with built-in networking and Oracle’s Sun ZFS Storage Appliance product line, the configuration provides high availability via the blade cluster as well as a documented best practice guide that helps reduce deployment time and cost for customers implementing highly virtualized applications or private cloud Infrastructure as a Service (IaaS) architectures. To further support easier, faster and lower-cost deployments, Oracle Linux, Oracle Solaris and Oracle VM are available for pre-install on select Sun x86 systems, and Oracle VM Templates are available for download for Oracle Applications, Oracle Fusion Middleware, Oracle Database, Oracle Real Application Clusters, and many other Oracle products. Key benefits of the Oracle VM blade cluster reference configuration include: Faster time to value – Begin deploying applications immediately because the optimized software stack is pre-configured for best practices and is ready-to-run on the recommended hardware platforms. Reduced deployment cost and risk – The entire hardware and software stack has been tested and is supported together by Oracle. Elastic scalability – As capacity needs grow, the system can be easily scaled in multiple dimensions with the ability to add compute, storage, and networking resources independently. For more information, see: Oracle white paper: Accelerating deployment of virtualized infrastructures with the Oracle VM blade cluster reference configuration Oracle technical white paper: Best Practices and Guidelines for Deploying the Oracle VM Blade Cluster Reference Configuration

Requirement refinement between two levels of specification

- by user107149

I am currently working on the definition of the documentation architecture of a system, from customers needs to software/hardware requirements. I encounter a big problem with the level of refinement of requirements. The classic architecture is : PTS -- SSS -- SSDD -- SRS/HRS with PTS : Purshaser Technical Specification SSS : Supplier System Specification SSDD : System Segment Design Description SRS / HRS : Software / Hardware Requirement Specification. Requirements from PTS are reworked in SSS, this document only expressed the needs (no design requirements are defined at this level). Then, the system design is described in SSDD : we allocate requirements from the SSS to functions from the design and functions are then allocated to component (Software or hardware) (we are still at the SSDD level). Finally, for each component, we write one SRS or one HRS. Requirements in SRS or HRS are refinement of requirements from SSS (and traceability matrix are made between these two levels). My problem is the following one : Our system is a complex one, and some of the requirements in the SSS needs to be refined twice to be at the right level in the SRS (means that software people can understand the requirement to make their coding). But, with this document architecture, I can only refine once the requirements from the SSS. The second problem is that only a part of the requirements from the SSS needs to be refined twice. The other part only need one refinement. On the picture below, the green boxes are requirements at the right level for SRS or HRS. And purple boxes are intermediate requirements which can not be included in SSS since they are design requirements. Where can I put these purple requirements ?? Is there someone who has already encountered this problem ? Should I write two documents at SRS level ? Should I include intermediate requirements in SSDD ? Should I includes the two refinement levels (purple and green) in the same SRS document (not sure that's possible since a SRS is only for one component) ??? Thanks for your help and expertise ;-)

The Making of Arduino [Geek History]

- by Jason Fitzpatrick

The open-source Arduino board is the heart of thousands of different DIY projects–it would be easy to think that the Arduino has always been around. The ubiquitous little hobby board, however, is but a scant six years old. At technology blog IEEESpectrum they delve into the history of the Arduino board and its quiet origins in a small Italian town. Here’s an excerpt from their lengthy write up about the the origin and history of the beloved Arduino: Arduino is a low-cost microcontroller board that lets even a novice do really amazing things. You can connect an Arduino to all kinds of sensors, lights, motors, and other devices and use easy-to-learn software to program how your creation will behave. You can build an interactive display or a mobile robot and then share your design with the world by posting it on the Net. Released in 2005 as a modest tool for Banzi’s students at the Interaction Design Institute Ivrea (IDII), Arduino has spawned an international do-it-yourself revolution in electronics. You can buy an Arduino board for just about US $30 or build your own from scratch: All hardware schematics and source code are available for free under public licenses. As a result, Arduino has become the most influential open-source hardware movement of its time. The little board is now the go-to gear for artists, hobbyists, students, and anyone with a gadgetry dream. More than 250 000 Arduino boards have been sold around the world—and that doesn’t include the reams of clones. “It made it possible for people do things they wouldn’t have done otherwise,” says David A. Mellis, who was a student at IDII before pursuing graduate work at the MIT Media Lab and is the lead software developer of Arduino.

What's up with LDoms: Part 1 - Introduction & Basic Concepts

- by Stefan Hinker

LDoms - the correct name is Oracle VM Server for SPARC - have been around for quite a while now. But to my surprise, I get more and more requests to explain how they work or to give advise on how to make good use of them. This made me think that writing up a few articles discussing the different features would be a good idea. Now - I don't intend to rewrite the LDoms Admin Guide or to copy and reformat the (hopefully) well known "Beginners Guide to LDoms" by Tony Shoumack from 2007. Those documents are very recommendable - especially the Beginners Guide, although based on LDoms 1.0, is still a good place to begin with. However, LDoms have come a long way since then, and I hope to contribute to their adoption by discussing how they work and what features there are today. In this and the following posts, I will use the term "LDoms" as a common abbreviation for Oracle VM Server for SPARC, just because it's a lot shorter and easier to type (and presumably, read). So, just to get everyone on the same baseline, lets briefly discuss the basic concepts of virtualization with LDoms. LDoms make use of a hypervisor as a layer of abstraction between real, physical hardware and virtual hardware. This virtual hardware is then used to create a number of guest systems which each behave very similar to a system running on bare metal: Each has its own OBP, each will install its own copy of the Solaris OS and each will see a certain amount of CPU, memory, disk and network resources available to it. Unlike some other type 1 hypervisors running on x86 hardware, the SPARC hypervisor is embedded in the system firmware and makes use both of supporting functions in the sun4v SPARC instruction set as well as the overall CPU architecture to fulfill its function. The CMT architecture of the supporting CPUs (T1 through T4) provide a large number of cores and threads to the OS. For example, the current T4 CPU has eight cores, each running 8 threads, for a total of 64 threads per socket. To the OS, this looks like 64 CPUs. The SPARC hypervisor, when creating guest systems, simply assigns a certain number of these threads exclusively to one guest, thus avoiding the overhead of having to schedule OS threads to CPUs, as do typical x86 hypervisors. The hypervisor only assigns CPUs and then steps aside. It is not involved in the actual work being dispatched from the OS to the CPU, all it does is maintain isolation between different guests. Likewise, memory is assigned exclusively to individual guests. Here, the hypervisor provides generic mappings between the physical hardware addresses and the guest's views on memory. Again, the hypervisor is not involved in the actual memory access, it only maintains isolation between guests. During the inital setup of a system with LDoms, you start with one special domain, called the Control Domain. Initially, this domain owns all the hardware available in the system, including all CPUs, all RAM and all IO resources. If you'd be running the system un-virtualized, this would be what you'd be working with. To allow for guests, you first resize this initial domain (also called a primary domain in LDoms speak), assigning it a small amount of CPU and memory. This frees up most of the available CPU and memory resources for guest domains. IO is a little more complex, but very straightforward. When LDoms 1.0 first came out, the only way to provide IO to guest systems was to create virtual disk and network services and attach guests to these services. In the meantime, several different ways to connect guest domains to IO have been developed, the most recent one being SR-IOV support for network devices released in version 2.2 of Oracle VM Server for SPARC. I will cover these more advanced features in detail later. For now, lets have a short look at the initial way IO was virtualized in LDoms: For virtualized IO, you create two services, one "Virtual Disk Service" or vds, and one "Virtual Switch" or vswitch. You can, of course, also create more of these, but that's more advanced than I want to cover in this introduction. These IO services now connect real, physical IO resources like a disk LUN or a networt port to the virtual devices that are assigned to guest domains. For disk IO, the normal case would be to connect a physical LUN (or some other storage option that I'll discuss later) to one specific guest. That guest would be assigned a virtual disk, which would appear to be just like a real LUN to the guest, while the IO is actually routed through the virtual disk service down to the physical device. For network, the vswitch acts very much like a real, physical ethernet switch - you connect one physical port to it for outside connectivity and define one or more connections per guest, just like you would plug cables between a real switch and a real system. For completeness, there is another service that provides console access to guest domains which mimics the behavior of serial terminal servers. The connections between the virtual devices on the guest's side and the virtual IO services in the primary domain are created by the hypervisor. It uses so called "Logical Domain Channels" or LDCs to create point-to-point connections between all of these devices and services. These LDCs work very similar to high speed serial connections and are configured automatically whenever the Control Domain adds or removes virtual IO. To see all this in action, now lets look at a first example. I will start with a newly installed machine and configure the control domain so that it's ready to create guest systems. In a first step, after we've installed the software, let's start the virtual console service and downsize the primary domain. root@sun # ldm list NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME primary active -n-c-- UART 512 261632M 0.3% 2d 13h 58m root@sun # ldm add-vconscon port-range=5000-5100 \ primary-console primary root@sun # svcadm enable vntsd root@sun # svcs vntsd STATE STIME FMRI online 9:53:21 svc:/ldoms/vntsd:default root@sun # ldm set-vcpu 16 primary root@sun # ldm set-mau 1 primary root@sun # ldm start-reconf primary root@sun # ldm set-memory 7680m primary root@sun # ldm add-config initial root@sun # shutdown -y -g0 -i6 So what have I done: I've defined a range of ports (5000-5100) for the virtual network terminal service and then started that service. The vnts will later provide console connections to guest systems, very much like serial NTS's do in the physical world. Next, I assigned 16 vCPUs (on this platform, a T3-4, that's two cores) to the primary domain, freeing the rest up for future guest systems. I also assigned one MAU to this domain. A MAU is a crypto unit in the T3 CPU. These need to be explicitly assigned to domains, just like CPU or memory. (This is no longer the case with T4 systems, where crypto is always available everywhere.) Before I reassigned the memory, I started what's called a "delayed reconfiguration" session. That avoids actually doing the change right away, which would take a considerable amount of time in this case. Instead, I'll need to reboot once I'm all done. I've assigned 7680MB of RAM to the primary. That's 8GB less the 512MB which the hypervisor uses for it's own private purposes. You can, depending on your needs, work with less. I'll spend a dedicated article on sizing, discussing the pros and cons in detail. Finally, just before the reboot, I saved my work on the ILOM, to make this configuration available after a powercycle of the box. (It'll always be available after a simple reboot, but the ILOM needs to know the configuration of the hypervisor after a power-cycle, before the primary domain is booted.) Now, lets create a first disk service and a first virtual switch which is connected to the physical network device igb2. We will later use these to connect virtual disks and virtual network ports of our guest systems to real world storage and network. root@sun # ldm add-vds primary-vds root@sun # ldm add-vswitch net-dev=igb2 switch-primary primary You are free to choose whatever names you like for the virtual disk service and the virtual switch. I strongly recommend that you choose names that make sense to you and describe the function of each service in the context of your implementation. For the vswitch, for example, you could choose names like "admin-vswitch" or "production-network" etc. This already concludes the configuration of the control domain. We've freed up considerable amounts of CPU and RAM for guest systems and created the necessary infrastructure - console, vts and vswitch - so that guests systems can actually interact with the outside world. The system is now ready to create guests, which I'll describe in the next section.

Spinup time failure

- by bioShark

I am not sure this is a real question or a bug I should report Ubuntu. Using: Ubuntu 11.10, on a Intel Q6600, Samsung Spinpoint F4 2TB. I have set my PC on Suspend and after I came back, pressed Enter and after logging in everything was back to normal. However, I had a message from Disk Utility that one disk reports errors. I entered Disk Utility, and my Samsung 2TB disk, the one on which my Ubuntu is installed, had the SMART Status turned red, with error message on it. The error was: Spinup time failed Value 21, Threshold value was 25 (so the error was reported because 21 < 25) I restarted and booted up in Windows to see what HD Tune is reporting. Unfortunately it was exactly the same 21/25. After reading up on Wiki about SMART and the errors, I discovered that Spinup time is the time required for the disk to reach full spinning speed in milliseconds. Then it hit me that, in Ubuntu I had Suspended the system, making essentially all my hardware stop. And when I rebooted to Windows, the hardware doesn't really stop, so SMART's reading of the Spinup time was still from Ubuntu's suspension. So I did a full PC stop and then booted up again, both in Ubuntu and Windows to see if there are different readings. Both reported successful Spinup time, 68 (a little better then 21 :) ), although in Disk Utility I have a nice message: Failed in the Past So now I am pretty sure that Ubuntu didn't handle the Suspend correctly, but then again should I worry about Imminent hardware failure ? Am I missing some drivers? Should I report this as a bug to Ubuntu? Sorry if this was a bad place to ask this question.

Are Intel compilers really better than Microsoft ones?

- by Rocket Surgeon

Years ago I was surprised when discovered that Intel sells Studio compatible compilers. I tried it in particular for C/C++ as well as fantastic diagnostic tools. But the code was simply not that computationally intensive to notice the difference. The only impression was: did Intel really did it for me just now, Wow, amazing tools with nanoseconds resolution, unbeleivable. But the trial ended and team never seriously considered a purchase. From your experience, if license cost does not matter, which vendor is a winner ? It is not broad or vague question or attemt to spark a holy war. This sort of question about 2 very visible tools. Nobody likes when tools have any mysteries or surprises. And choices between best and best are always the pain. I also understand the "grass greener" argument. I want to hear all "what ifs" stories. What if Intel just locally optimizes it for the chip stepping of the month, and not every hardware target will actually work as well as Microsoft compiled ? What if AMD hardware is the target and everything will slow down for no reason ? Or on other hand, what if Intel's hardware has so many unnoticable opportunities, that Microsoft compiler writers are too slow to adopt and never implement in the compiler ? What if both are the same exactly, actually a single codebase just wrapped into 2 different boxes and licensed to both vendors by some 3rd party shop? And so on. But someone knows some answers.

Attempting to install netgear N300 Wireless USB Adapter on Ubuntu without a present internet connection

- by Liz

Hello Linux/Ubuntu world out there. I don't have internet presently on the desktop I am trying to install the USB wireless adapter on. This seems to be the problem, which if the hardware would work would theoretically fix the problem. I can NOT access the internet via anything but wireless. I am presently on my laptop searching for answers while trying to install this little device. So any advice will have to take that into account. Now I have tried so far, using WINE which does not want to work, I have tried Windows Wireless Drivers which doesn't want to work, I have tried Software Sources, Other Software and it will not acknowledge the cdrom as a repository stating errors like E:Unable to stat the mount point /cdrom/ -stat (2: No such file or directory) However I can open the CD icon on my computer and access and browse the files. The computer can read the CD. I can read the CD. I've tried just plugging it in and seeing if the computer will automatically recognize the hardware, and go from there. That does not work either. I have tested USB port to just verify that the USB port works. It does. My laptop recognizes the hardware, and would easily install the software if I prompted it to. The difference is that my laptop is Vista, and I HATE Vista. Any tips, tricks?

Data Management Business Continuity Planning

Business Continuity Governance In order to ensure data continuity for an organization, they need to ensure they know how to handle a data or network emergency because all systems have the potential to fail. Data Continuity Checklist: Disaster Recovery Plan/Policy Backups Redundancy Trained Staff Business Continuity Policies In order to protect data in case of any emergency a company needs to put in place a Disaster recovery plan and policies that can be executed by IT staff to ensure the continuity of the existing data and/or limit the amount of data that is not contiguous. A disaster recovery plan is a comprehensive statement of consistent actions to be taken before, during and after a disaster, according to Geoffrey H. Wold. He also states that the primary objective of disaster recovery planning is to protect the organization in the event that all or parts of its operations and/or computer services are rendered unusable. Furthermore, companies can mandate through policies that IT must maintain redundant hardware in case of any hardware failures and redundant network connectivity incase the primary internet service provider goes down. Additionally, they can require that all staff be trained in regards to the Disaster recovery policy to ensure that all parties evolved are knowledgeable to execute the recovery plan. Business Continuity Procedures Business continuity procedure vary from organization to origination, however there are standard procedures that most originations should follow. Standard Business Continuity Procedures Backup and Test Backups to ensure that they work Hire knowledgeable and trainable staff Offer training on new and existing systems Regularly monitor, test, maintain, and upgrade existing system hardware and applications Maintain redundancy regarding all data, and critical business functionality

xorg-edgers PPA with llvmpipe breaks AMD APU system

- by linux_RRT

I've read before where this had happened to another user with the same system... I was running Ubuntu 12.04 LTS with Kernel 3.2.0.29 and decided to give xorg-edgers a try. I purged fglrx* and xorg* before beginning. I upgraded with sudo apt-get upgrade -d The system downloaded and installed 109MB worth of data to the system, including llvmpipe which I am very unfamiliar with, and Kernel 3.5.0.11. The system was then rebooted to finalize the upgrade. The system boots to a black screen and then tells me "The system is running in low-graphics mode". Did I miss a step in the install? Or do the newest open-source drivers just not work with my hardware? I realize this hardware (APU) is some of the newer development. I dropped to command via the fallback menu and attempted to boot lightdm as root, but the system hangs in 'Configuring kernel parameters' at Starting initializes zram swaping. ...and then it just sits there. The other thing that concerns me is the output at the top of the screen that says: could not write bytes: Broken pipe Does llvmpipe work for this type of system? To be clear the system is: MSI x370-206us Laptop Radeon HD 6320 AMD e450 APU 1.67ghz dual-core Any help would be much appreciated. Like I said, I'm pretty sure I followed the right order of operations for the install procedure, but I was curious if anyone with similar hardware had experienced anything similar.

HP Envy dv6t-7300: Disabled WiFi through button and can't enable it anymore

- by Mateus B. Cassiano

Well, I have a HP Envy dv6t-7300 laptop that came with a Ralink RT5390 WiFi card. Everything was working perfectly, and eventually I press the WiFi button in my keyboard to toggle the card on/off. Until today, all worked right: if the wifi was off (wifi LED amber) and I press the wifi button, after a few seconds the LED turn white and everything works. If I repeat the process, the wifi LED turn amber and the card get disabled, but now, I can't turn it on anymore. running sudo rfkill list all I get: 0: phy0: Wireless LAN Soft blocked: no Hard blocked: no 1: hp-wifi: Wireless LAN Soft blocked: no Hard blocked: yes So, I ran sudo rfkill unblock all but nothing changed. As a side note, if I run sudo ifconfig wlan0 up, the indicator LED gets white (indicating that the card was enabled), but Ubuntu still say that the card is blocked by hardware. Extra information: the card works without issues in windows and in Ubuntu installer (booting from a live CD). I'm using the card out-of-box, using the drivers already included in Ubuntu 12.10. The module rt2800pci is loaded and working fine, not blacklisted, etc, etc. The card and the button toggle worked flawlessly until today, when I toggled it off and can't turn it on anymore... The problem is back, but in a different manner: if I don't press the wifi key a few times during the grub loading, in the login screen the wifi button will be ambar (disabled), pressing it will toggle it white (enabled) or ambar (disabled) again, but ubuntu still says that the network card was disabled by hardware and doesn't connect... In other words, if I don't press the WiFi button a few times when Ubuntu is booting, it will be stuck with the "network card was disabled by hardware" message, even if the light is white (enabled). Any clue? Maybe a error in some startup script or config file?

Most suited technology for browser games?

- by Tingle

I was thinking about making a 2D MMO which I would in the long run support on various plattforms like desktop, mac, browser, android and ios. The server will be c++/linux based and the first client would go in the browser. So I have done some research and found that webgl and flash 11 support hardware accelerated rendering, I saw some other things like normal HTML5 painting. So my question is, which technology should I use for such a project? My main goal would be that the users have a hassle free experience using what there hardware can give them with hardware acceleration. And the client should work on the most basic out-of-the-box pc's that any casual pc or mac user has. And another criteria would be that it should be developer friendly. I've messed with webgl abit for example and that would require writing a engine from scratch - which is acceptable but not preferred. Also, in case of non-actionscript, which kind language is most prefered in terms of speed and flexability. I'm not to fond of javascript due to the garbage collector but have learned to work around it. Thank you for you time.
