• Authlogic OpenID integration

  - by Craig

  I'm having difficulty getting OpenId authentication working with Authlogic. It appears that the problem arose with changes to the open_id_authentication plugin. From what I've read so far, one needs to switch from using gems to using plugins. Here's what I done thus far to get Authlogic-OpenID integration working: Removed relevant gems: authlogic authlogic-oid rack-openid ruby-openid * Installed, configured, and started the authlogic sample application (http://github.com/binarylogic/authlogic_example)--works as expected. This required: installing the authlogic (2.1.3) gem ($ sudo gem install authlogic) adding a dependency (config.gem "authlogic") to the environment.rb file. added migration to add open-id support to User model; ran migration; columns added as expected made changes to the UsersController and UserSessionsController to use blocks to save each. made changes to new user-sessions view to support open id (f.text_field :openid_identifier) installed open_id_authentication plugin ($ script/plugin install git://github.com/rails/open_id_authentication.git) installed the authlogic-oid plugin ($ script/plugin install git://github.com/binarylogic/authlogic_openid.git) installed the plugin ($ script/plugin install git://github.com/glebm/ruby-openid.git) restarted mongrel (CTRL-C; $ script/server) Mogrel failed to start, returning the following error: /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `gem_original_require': no such file to load -- rack/openid (MissingSourceFile) from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `require' from /Users/craibuc/NetBeansProjects/authlogic_example/vendor/rails/activesupport/lib/active_support/dependencies.rb:156:in `require' from /Users/craibuc/NetBeansProjects/authlogic_example/vendor/rails/activesupport/lib/active_support/dependencies.rb:521:in `new_constants_in' from /Users/craibuc/NetBeansProjects/authlogic_example/vendor/rails/activesupport/lib/active_support/dependencies.rb:156:in `require' from /Users/craibuc/NetBeansProjects/authlogic_example/vendor/plugins/open_id_authentication/lib/open_id_authentication.rb:3 from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `gem_original_require' from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `require' from /Users/craibuc/NetBeansProjects/authlogic_example/vendor/rails/activesupport/lib/active_support/dependencies.rb:156:in `require' from /Users/craibuc/NetBeansProjects/authlogic_example/vendor/rails/activesupport/lib/active_support/dependencies.rb:521:in `new_constants_in' from /Users/craibuc/NetBeansProjects/authlogic_example/vendor/rails/activesupport/lib/active_support/dependencies.rb:156:in `require' from /Users/craibuc/NetBeansProjects/authlogic_example/vendor/plugins/open_id_authentication/init.rb:5:in `evaluate_init_rb' from ./script/../config/../vendor/rails/railties/lib/rails/plugin.rb:146:in `evaluate_init_rb' from /Users/craibuc/NetBeansProjects/authlogic_example/vendor/rails/activesupport/lib/active_support/core_ext/kernel/reporting.rb:11:in `silence_warnings' from ./script/../config/../vendor/rails/railties/lib/rails/plugin.rb:142:in `evaluate_init_rb' from ./script/../config/../vendor/rails/railties/lib/rails/plugin.rb:48:in `load' from ./script/../config/../vendor/rails/railties/lib/rails/plugin/loader.rb:38:in `load_plugins' from ./script/../config/../vendor/rails/railties/lib/rails/plugin/loader.rb:37:in `each' from ./script/../config/../vendor/rails/railties/lib/rails/plugin/loader.rb:37:in `load_plugins' from ./script/../config/../vendor/rails/railties/lib/initializer.rb:348:in `load_plugins' from ./script/../config/../vendor/rails/railties/lib/initializer.rb:163:in `process' from ./script/../config/../vendor/rails/railties/lib/initializer.rb:113:in `send' from ./script/../config/../vendor/rails/railties/lib/initializer.rb:113:in `run' from /Users/craibuc/NetBeansProjects/authlogic_example/config/environment.rb:13 from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `gem_original_require' from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `require' from /Users/craibuc/NetBeansProjects/authlogic_example/vendor/rails/activesupport/lib/active_support/dependencies.rb:156:in `require' from /Users/craibuc/NetBeansProjects/authlogic_example/vendor/rails/activesupport/lib/active_support/dependencies.rb:521:in `new_constants_in' from /Users/craibuc/NetBeansProjects/authlogic_example/vendor/rails/activesupport/lib/active_support/dependencies.rb:156:in `require' from /Users/craibuc/NetBeansProjects/authlogic_example/vendor/rails/railties/lib/commands/server.rb:84 from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `gem_original_require' from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `require' from script/server:3 I suspect this is related the rack-openid gem, but as it was dependent upon the ruby-openid gem, it was removed when the ruby-openid gem was removed. Perhaps this can be installed as a plugin. Any assistance with this matter is greatly appreciated--I'm just about to give up on OpenId integration. * ruby-openid (2.1.2) is installed at /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8. I'm not certain if this is affecting anything. In any case, I'm not sure how to uninstall it or if I should. ** edit ** It appears that there are a number of gems in the /Library/Ruby/Gems/1.8/gems directory that may be causing an issue: authlogic-oid (1.0.4) rack-openid (1.0.3) ruby-openid (2.1.7) Questions: - why doesn't the gem list command list these gems? - Why doesn't the gem uninstall command remove these gems?

• Unknown error sourcing a script containing 'typeset -r' wrapped in command substitution

  - by Bernard Assaf

  I wish to source a script, print the value of a variable this script defines, and then have this value be assigned to a variable on the command line with command substitution wrapping the source/print commands. This works on ksh88 but not on ksh93 and I am wondering why. $ cat typeset_err.ksh #!/bin/ksh unset _typeset_var typeset -i -r _typeset_var=1 DIR=init # this is the variable I want to print When run on ksh88 (in this case, an AIX 6.1 box), the output is as follows: $ A=$(. ./typeset_err.ksh; print $DIR) $ echo $A init When run on ksh93 (in this case, a Linux machine), the output is as follows: $ A=$(. ./typeset_err.ksh; print $DIR) -ksh: _typeset_var: is read only $ print $A ($A is undefined) The above is just an example script. The actual thing I wish to accomplish is to source a script that sets values to many variables, so that I can print just one of its values, e.g. $DIR, and have $A equal that value. I do not know in advance the value of $DIR, but I need to copy files to $DIR during execution of a different batch script. Therefore the idea I had was to source the script in order to define its variables, print the one I wanted, then have that print's output be assigned to another variable via $(...) syntax. Admittedly a bit of a hack, but I don't want to source the entire sub-script in the batch script's environment because I only need one of its variables. The typeset -r code in the beginning is the error. The script I'm sourcing contains this in order to provide a semaphore of sorts--to prevent the script from being sourced more than once in the environment. (There is an if statement in the real script that checks for _typeset_var = 1, and exits if it is already set.) So I know I can take this out and get $DIR to print fine, but the constraints of the problem include keeping the typeset -i -r. In the example script I put an unset in first, to ensure _typeset_var isn't already defined. By the way I do know that it is not possible to unset a typeset -r variable, according to ksh93's man page for ksh. There are ways to code around this error. The favorite now is to not use typeset, but just set the semaphore without typeset (e.g. _typeset_var=1), but the error with the code as-is remains as a curiosity to me, and I want to see if anyone can explain why this is happening. By the way, another idea I abandoned was to grep the variable I need out of its containing script, then print that one variable for $A to be set to; however, the variable ($DIR in the example above) might be set to another variable's value (e.g. DIR=$dom/init), and that other variable might be defined earlier in the script; therefore, I need to source the entire script to make sure I all variables are defined so that $DIR is correctly defined when sourcing.

• Calling system commands from Perl

  - by Dan J

  In an older version of our code, we called out from Perl to do an LDAP search as follows: # Pass the base DN in via the ldapsearch-specific environment variable # (rather than as the "-b" paramater) to avoid problems of shell # interpretation of special characters in the DN. $ENV{LDAP_BASEDN} = $ldn; $lcmd = "ldapsearch -x -T -1 -h $gLdapServer" . <snip> " > $lworkfile 2>&1"; system($lcmd); if (($? != 0) || (! -e "$lworkfile")) { # Handle the error } The code above would result in a successful LDAP search, and the output of that search would be in the file $lworkfile. Unfortunately, we recently reconfigured openldap on this server so that a "BASE DC=" is specified in /etc/openldap/ldap.conf and /etc/ldap.conf. That change seems to mean ldapsearch ignores the LDAP_BASEDN environment variable, and so my ldapsearch fails. I've tried a couple of different fixes but without success so far: (1) I tried going back to using the "-b" argument to ldapsearch, but escaping the shell metacharacters. I started writing the escaping code: my $ldn_escaped = $ldn; $ldn_escaped =~ s/\/\\/g; $ldn_escaped =~ s/`/\`/g; $ldn_escaped =~ s/$/\$/g; $ldn_escaped =~ s/"/\"/g; That threw up some Perl errors because I haven't escaped those regexes properly in Perl (the line number matches the regex with the backticks in). Backticks found where operator expected at /tmp/mycommand line 404, at end of line At the same time I started to doubt this approach and looked for a better one. (2) I then saw some Stackoverflow questions (here and here) that suggested a better solution. Here's the code: print("Processing..."); # Pass the arguments to ldapsearch by invoking open() with an array. # This ensures the shell does NOT interpret shell metacharacters. my(@cmd_args) = ("-x", "-T", "-1", "-h", "$gLdapPool", "-b", "$ldn", <snip> ); $lcmd = "ldapsearch"; open my $lldap_output, "-|", $lcmd, @cmd_args; while (my $lline = <$lldap_output>) { # I can parse the contents of my file fine } $lldap_output->close; The two problems I am having with approach (2) are: a) Calling open or system with an array of arguments does not let me pass > $lworkfile 2>&1 to the command, so I can't stop the ldapsearch output being sent to screen, which makes my output look ugly: Processing...ldap_bind: Success (0) additional info: Success b) I can't figure out how to choose which location (i.e. path and file name) to the file handle passed to open, i.e. I don't know where $lldap_output is. Can I move/rename it, or inspect it to find out where it is (or is it not actually saved to disk)? Based on the problems with (2), this makes me think I should return back to approach (1), but I'm not quite sure how to

• How do I get through proxy server environments for non-standard services?

  - by Ripred

  I'm not real hip on exactly what role(s) today's proxy servers can play and I'm learning so go easy on me :-) I have a client/server system I have written using a homegrown protocol and need to enhance the client side to negotiate its way out of a proxy environment. I have an existing client and server system written in C and C++ for the speed and a small amount of MFC in the client to handle the user interface. I have written both the server and client side of the system on Windows (the people I work for are mainly web developers using Windows everything - not a choice) sticking to Berkeley Sockets as it were via wsock32 for efficiency. The clients connect to the server through a nonstandard port (even though using port 80 is an option to get out of some environments but the protocol that goes over it isn't HTTP). The TCP connection(s) stay open for the duration of the clients participation in real time conferences. Our customer base is expanding to all kinds of networked environments. I have been able to solve a lot of problems by adding the ability to connect securely over port 443 and using secure sockets which allows the protocol to pass through a lot environments since the internal packets can't be sniffed. But more and more of our customers are behind a proxy server environment and my direct connections don't make it through. My old school understanding of proxy servers is that they act as a proxy for external HTML content over HTTP, possibly locally caching popular material for faster local access, and also allowing their IT staff to blacklist certain destination sites. Customer are complaining that my software doesn't recognize and easily navigate its way through their proxy environments but I'm finding it difficult to decide what my "best fit" solution should be. My software doesn't tear down the connection after each client request, and on top of that packets can come from either side at any time, basically your typical custom client/server system for a specific niche. My first reaction is "why can't they just add my servers addresses to their white list" but if there is a programmatic way I can get through without requiring their IT staff to help it is politically better and arguably a better solution anyway. Plus maybe I'm still not understanding the role and purpose of what proxy servers and environments have grown to be these days. My first attempt at a solution was to use WinInet with its various proxy capabilities to establish a connection over port 80 to my non-standard protocol server (which knows enough to recognize and answer a simple HTTP-looking GET request and answer it with a simple HTTP response page to get around some environments that employ initial packet sniffing (DPI)). I retrieved the actual SOCKET handle behind WinInet's HINTERNET request object and had hoped to use that in place of my software's existing SOCKET connection and hopefully not need to change much more on the client side. It initially seemed to be my solution but on further inspection it seems that the OS gets first-chance at the received data on this socket since when I get notified of events via the standard select(...) statement on the socket and query the size of the data available via ioctlsocket the call succeeds but returns 0 bytes available, the reads don't work and it goes downhill from there. Can someone tell me of a client-side library (commercial is fine) will let me get past these proxy server environments with as little user and IT staff help as possible? From what I read it has grown past SOCKS and I figure someone has to have solved this problem before me. Thanks for reading my long-winded question, Ripred

• Android: MediaPlayer gapless or seamless Video Playing

  - by John Wang

  I can play the videos fine back to back by implementing the OnCompletionListener to set the data source to a different file. No problems there. I call reset() and prepare() just fine. What I haven't been able to figure out, is how to get rid of the 1-2 second gap screen flicker between the data source change and the new video starting. The gap shows a black screen, and I haven't found any way to get around it. I've tried setting the background of the parent view to an image, but it manages to bypass that. Even if the SurfaceView is transparent (which it is by default.) I've also tried to have the multiple video files played at the same time, and switching mediaplayer's display when one ends and the other is supposed to start. The last thing I tried, was to have a second view in the background that I show temporarily while the video is "preparing" and removing it when the video is ready to start. That also wasn't very seamless. Is there any way to get rid of that gap. Running a video in a loop works wonderfully and does exactly what I want with the exception that it's looking through the same video instead of playing a different one that I pick. main.xml <?xml version="1.0" encoding="utf-8"?> <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:background="@drawable/background" android:layout_height="fill_parent"> <SurfaceView android:id="@+id/surface" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_gravity="center"> </SurfaceView> </FrameLayout> Player.java public class Player extends Activity implements OnCompletionListener, MediaPlayer.OnPreparedListener, SurfaceHolder.Callback { private MediaPlayer player; private SurfaceView surface; private SurfaceHolder holder; public void onCreate(Bundle b) { super.onCreate(b); setContentView(R.layout.main); surface = (SurfaceView)findViewById(R.id.surface); holder = surface.getHolder(); holder.addCallback(this); holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); } public void onCompletion(MediaPlayer arg0) { File clip = new File(Environment.getExternalStorageDirectory(),"file2.mp4"); playVideo(clip.getAbsolutePath()); } public void onPrepared(MediaPlayer mediaplayer) { holder.setFixedSize(player.getVideoWidth(), player.getVideoHeight()); player.start(); } private void playVideo(String url) { try { File clip = new File(Environment.getExternalStorageDirectory(),"file1.mp4"); if (player == null) { player = new MediaPlayer(); player.setScreenOnWhilePlaying(true); } else { player.stop(); player.reset(); } player.setDataSource(url); player.setDisplay(holder); player.setOnPreparedListener(this); player.prepare(); player.setOnCompletionListener(this); } catch (Throwable t) { Log.e("ERROR", "Exception Error", t); } }

• Reflector error or optimisation?

  - by David_001

  Long story short: I used reflector on the System.Security.Util.Tokenizer class, and there's loads of goto statements in there. Here's a brief example snippet: Label_0026: if (this._inSavedCharacter != -1) { num = this._inSavedCharacter; this._inSavedCharacter = -1; } else { switch (this._inTokenSource) { case TokenSource.UnicodeByteArray: if ((this._inIndex + 1) < this._inSize) { break; } stream.AddToken(-1); return; case TokenSource.UTF8ByteArray: if (this._inIndex < this._inSize) { goto Label_00CF; } stream.AddToken(-1); return; case TokenSource.ASCIIByteArray: if (this._inIndex < this._inSize) { goto Label_023C; } stream.AddToken(-1); return; case TokenSource.CharArray: if (this._inIndex < this._inSize) { goto Label_0272; } stream.AddToken(-1); return; case TokenSource.String: if (this._inIndex < this._inSize) { goto Label_02A8; } stream.AddToken(-1); return; case TokenSource.NestedStrings: if (this._inNestedSize == 0) { goto Label_030D; } if (this._inNestedIndex >= this._inNestedSize) { goto Label_0306; } num = this._inNestedString[this._inNestedIndex++]; goto Label_0402; default: num = this._inTokenReader.Read(); if (num == -1) { stream.AddToken(-1); return; } goto Label_0402; } num = (this._inBytes[this._inIndex + 1] << 8) + this._inBytes[this._inIndex]; this._inIndex += 2; } goto Label_0402; Label_00CF: num = this._inBytes[this._inIndex++]; if ((num & 0x80) != 0) { switch (((num & 240) >> 4)) { case 8: case 9: case 10: case 11: throw new XmlSyntaxException(this.LineNo); case 12: case 13: num &= 0x1f; num3 = 2; break; case 14: num &= 15; num3 = 3; break; case 15: throw new XmlSyntaxException(this.LineNo); } if (this._inIndex >= this._inSize) { throw new XmlSyntaxException(this.LineNo, Environment.GetResourceString("XMLSyntax_UnexpectedEndOfFile")); } byte num2 = this._inBytes[this._inIndex++]; if ((num2 & 0xc0) != 0x80) { throw new XmlSyntaxException(this.LineNo); } num = (num << 6) | (num2 & 0x3f); if (num3 != 2) { if (this._inIndex >= this._inSize) { throw new XmlSyntaxException(this.LineNo, Environment.GetResourceString("XMLSyntax_UnexpectedEndOfFile")); } num2 = this._inBytes[this._inIndex++]; if ((num2 & 0xc0) != 0x80) { throw new XmlSyntaxException(this.LineNo); } num = (num << 6) | (num2 & 0x3f); } } goto Label_0402; Label_023C: num = this._inBytes[this._inIndex++]; goto Label_0402; Label_0272: num = this._inChars[this._inIndex++]; goto Label_0402; Label_02A8: num = this._inString[this._inIndex++]; goto Label_0402; Label_0306: this._inNestedSize = 0; I essentially wanted to know how the class worked, but the number of goto's makes it impossible. Arguably something like a Tokenizer class needs to be heavily optimised, so my question is: is Reflector getting it wrong, or is goto an optimisation for this class?

• Java fatal error, don't know what it means

  - by Thomas King

  It happens at the same place in my code (albeit not the first time the method is executed) but I can't make head or tail of what is wrong. (Doubly so as it's code for a robot). Be most appreciative if someone can give me an idea of what kind of problem it is. I assume it's to do with threading (multi-threaded app) but I don't really know what?!? Worried as deadline for uni project is looming!!!

• Example: Communication between Activity and Service using Messaging

  - by Lance Lefebure

  I couldn't find any examples of how to send messages between an activity and a service, and spent far too many hours figuring this out. Here is an example project for others to reference. This example allows you to start or stop a service directly, and separately bind/unbind from the service. When the service is running, it increments a number at 10Hz. If the activity is bound to the service, it will display the current value. Data is transferred as an Integer and as a String so you can see how to do that two different ways. There are also buttons in the activity to send messages to the service (changes the increment-by value).

• Android app crashes on emulator - logCat shows no errors

  - by David Miler

  I have just added the SherlockActionBar library to my android project. After some small changes (FragmentActivity - SherlockFragmentActivity, getActionBar() - getSupportActionBar(), imports) it all compiled nicely. After I run the app, however, the debugger stops, as though it had encountered an exception. However, there are no errors shown in the LogCat output. I just can't wrap my head around what's going on. Here is the logCat output after I terminate the app. 10-02 14:11:19.227: I/SystemUpdateService(174): UpdateTask at time 1349187079227 10-02 14:11:19.237: I/ActivityThread(328): Pub com.android.email.attachmentprovider: com.android.email.provider.AttachmentProvider 10-02 14:11:19.687: I/dalvikvm(81): Jit: resizing JitTable from 512 to 1024 10-02 14:11:19.809: D/MediaScannerService(150): start scanning volume internal: [/system/media] 10-02 14:11:20.047: V/AlarmClock(239): AlarmInitReceiver finished 10-02 14:11:20.087: I/ActivityManager(81): Start proc com.android.quicksearchbox for broadcast com.android.quicksearchbox/.SearchWidgetProvider: pid=346 uid=10012 gids={3003} 10-02 14:11:20.127: D/ExchangeService(320): !!!

• Example: Communication between Activity and Service using Messaging

  - by Lance Lefebure

  I couldn't find any examples of how to send messages between an activity and a service, and spent far too many hours figuring this out. Here is an example project for others to reference. This example allows you to start or stop a service directly, and separately bind/unbind from the service. When the service is running, it increments a number at 10Hz. If the activity is bound to the service, it will display the current value. Data is transferred as an Integer and as a String so you can see how to do that two different ways. There are also buttons in the activity to send messages to the service (changes the increment-by value).

• How TiVo is messing up customer support.

  - by James Fleming

  Ok,  So I've gotten a TiVo and overall, I'm happy, but there have been issues and I suspect I've a defective unit. - Now the nice folks after many service calls were happy to swap it out, and to ensure continuity of service, they sent me a new unit (after a $109 deposit).  That was yesterday. Today, when we go to watch a little TV, and wait for our replacement unit to arrive we find our TiVo service has been suspended. WTF? They have an exchange program, but your unit your waiting to exchange is as dead as a doornail until the replacement arrives. How hard is it to keep the old unit active for an extra week? Here is the exchange w/Tivo below... You are currently number 1 in the queue. We apologize for the delay. We will assign you to an agent as soon as one is available.The average amount of time a customer has to wait is 00:13.  Kaylene (Listening)  Kaylene: Thank you for contacting TiVo! My name is Kaylene. So that I may better assist you, are you an existing customer?  james Fleming: yes I am, but I'm now having second thoughts about being one    Kaylene: Thank you for verifying your information. How may I assist you today James?  james Fleming: I've been having issues w/a tivo box & I'm getting a replacement sent out to me (after paying an additional deposit) and now my current unit is no longer activated  Kaylene: I can help you today!  Kaylene: When we process an exchange we do transfer over the service to the replacement box so it is active and ready to go when you receive it.  james Fleming: which is to say you also make my current box worthless until such time I receive a new box?!?!?  Kaylene: I apologize that your original box was deactivated so we could activate your replacement box.  james Fleming: Why on Earth would I bother to pay in advance for a new box if you were going to kill my existing box.  Kaylene: What features are you needing to use on your current box?  james Fleming: I need to be able to access my netflix subscription (if I'm lucky enough to have it work without rebooting)  Kaylene: Can I have you verify the TiVo Service Number of your TiVo box please?  james Fleming: 7460011906979b4  Kaylene: We have your current box temporary service but not all features are available with temporary service as it is not paid for service.  Kaylene: If you like I can transfer your service back to your current box for now. Then once you receive the new box you will have to call in and have the service transferred back to the new box.  james Fleming: Not paid for? Let's see> one tivo box + 3 year service plan + monthly service + $109 deposit on a second box = what?  Kaylene: Would you like me to transfer your service back to your current box?  james Fleming: Yes - that would be helpful  Kaylene: All you will need to do is contact us again once you receive the new box so we can transfer it back.  Kaylene: I have put your service back on TiVo box 7460011906979b4.  james Fleming: What would also be helpful is your firm informing me to how you'd be cutting service in the interim.  james Fleming: Again - I opted to pay to have a second box delivered BEFORE returning the box I have - thus trying to have a continuity of service..  Kaylene: This is not something we normally do so it is important when you contact us to transfer the service back to the new box when you receive it that you reference this case number: 110622-006089.  Kaylene: I apologize about the inconvenience. You may need  force a few connections for the box to recognize the service again.  james Fleming: If it's not something you normally do than WHY would you have a $109 fee and a term for the service.  james Fleming: I am not mad at you, but your company is not impressing me and I'm blogging about this experience  Kaylene: Again I apologize about the inconvenience but you should be good to go now.

• SanjayP&rsquo;s venture after Microsoft involves no Microsoft

  - by eddraper

  When I was at Microsoft, I always found Sanjay Parthasarathy to be a bright and passionate leader.  While he was a bit disconnected at times with what was really going on out in the trenches, I always thought he was true believer in what we in Developer Platform and Evangelism (DPE) were doing.  He got it.  He had started DPE and kicked a lot of doors down up in Redmond to make it happen.  Back in the early 2000s, battles over platform choices at large customers was trench warfare… bayonets and hand grenades at the P-Code level.  This model was not at all suited to Microsoft’s org structure at the time.  While there were plenty of people fully able to have competitive conversations around Windows Server, or AD, or Exchange, or the desktop, there weren’t many that could have deep technical conversations around Java vs .NET and the platform “stack” as a cohesive, unified unit of value.  This task fell to DPE. Sanjay ended up leaving Microsoft a number of months before me in 2009 and I remember thinking these exact words: “holy shit, SanjayP left Microsoft.”  When SanjayP left DPE years before that,  Sheila Gulati had stepped into his shoes and I thought we where starting to miss a beat.  Sheila had built an amazing business at Microsoft India, but I don’t recall being inspired by her as a leader.  SanjayP’s talks felt like the opening scene of “Patton” with George C. Scott pacing in front of the American flag.  Sheila was a voice on a con-call.  When she moved on in 2007, Walid Abu-Hadba was given the reigns.  Personally, I don’t ever recall even seeing his face.  I think I might recall hearing his voice on some con-calls, but for all intents and purposes he was invisible to me.  Perhaps this was the beginning of my carelessness around seeking “visibility.” Fast forward to Build 2011.  First off, we have no PDC – we have Build.  Microsoft had made an 11 year investment by this time in building an organization to make its technology relevant to developers.  One would think such an org would be in the driver’s seat of such an event, but we see Windows product group people on the podiums.  Watching, I could see the messaging unfold… but no story.  It was like the old days.  Demos and PowerPoints by team members building the tech, and in many cases VPs.  The ensuing confusion is almost legendary now.  Windows 8 was, and is, a pretty big deal… but who is telling the story – not just features and benefits, but the story around how it all fits together. Having been out of Microsoft for two years now, and looking in, I can only conclude that the “DPE of old” has at best been emasculated, and at worst been completely marginalized by internal politics, or perhaps the eternal march of the corporate entropy generator that resides at all large companies.  I don’t think this is a good thing for anyone. And now, back to Sanjay who is the father of Microsoft DPE… I noticed that he has moved back to India and is doing start-up work.  His current company Indix looks to be doing some interesting things with “big data” and here’s their stack: Nary a trace of anything Microsoft.  What could account for this?  I wonder….  Better availability of labor and expertise in India for this stack?  Donno, but even in India, leet R and Hadoop skills have to be hard to find. Technical superiority?  This, I sincerely doubt. This stack, with SanjayP’s name as CEO leaves me with an unsettling feeling.  If he did believe, he no longer does.  One doesn’t place bets with real money on things they don’t believe in.  Perhaps he never did believe, and was a corporate creature seeking to find a niche for himself after which he manipulated me and others.  Or perhaps… anger… be it passive aggression or an outright “in your face F*** you” to his former masters. I guess in the end, only he knows the true reason… But I have my theory...

• Rendering ASP.NET MVC Razor Views outside of MVC revisited

  - by Rick Strahl

  Last year I posted a detailed article on how to render Razor Views to string both inside of ASP.NET MVC and outside of it. In that article I showed several different approaches to capture the rendering output. The first and easiest is to use an existing MVC Controller Context to render a view by simply passing the controller context which is fairly trivial and I demonstrated a simple ViewRenderer class that simplified the process down to a couple lines of code. However, if no Controller Context is available the process is not quite as straight forward and I referenced an old, much more complex example that uses my RazorHosting library, which is a custom self-contained implementation of the Razor templating engine that can be hosted completely outside of ASP.NET. While it works inside of ASP.NET, it’s an awkward solution when running inside of ASP.NET, because it requires a bit of setup to run efficiently.Well, it turns out that I missed something in the original article, namely that it is possible to create a ControllerContext, if you have a controller instance, even if MVC didn’t create that instance. Creating a Controller Instance outside of MVCThe trick to make this work is to create an MVC Controller instance – any Controller instance – and then configure a ControllerContext through that instance. As long as an HttpContext.Current is available it’s possible to create a fully functional controller context as Razor can get all the necessary context information from the HttpContextWrapper().The key to make this work is the following method:/// <summary> /// Creates an instance of an MVC controller from scratch /// when no existing ControllerContext is present /// </summary> /// <typeparam name="T">Type of the controller to create</typeparam> /// <returns>Controller Context for T</returns> /// <exception cref="InvalidOperationException">thrown if HttpContext not available</exception> public static T CreateController<T>(RouteData routeData = null) where T : Controller, new() { // create a disconnected controller instance T controller = new T(); // get context wrapper from HttpContext if available HttpContextBase wrapper = null; if (HttpContext.Current != null) wrapper = new HttpContextWrapper(System.Web.HttpContext.Current); else throw new InvalidOperationException( "Can't create Controller Context if no active HttpContext instance is available."); if (routeData == null) routeData = new RouteData(); // add the controller routing if not existing if (!routeData.Values.ContainsKey("controller") && !routeData.Values.ContainsKey("Controller")) routeData.Values.Add("controller", controller.GetType().Name .ToLower() .Replace("controller", "")); controller.ControllerContext = new ControllerContext(wrapper, routeData, controller); return controller; }This method creates an instance of a Controller class from an existing HttpContext which means this code should work from anywhere within ASP.NET to create a controller instance that’s ready to be rendered. This means you can use this from within an Application_Error handler as I needed to or even from within a WebAPI controller as long as it’s running inside of ASP.NET (ie. not self-hosted). Nice.So using the ViewRenderer class from the previous article I can now very easily render an MVC view outside of the context of MVC. Here’s what I ended up in my Application’s custom error HttpModule: protected override void OnDisplayError(WebErrorHandler errorHandler, ErrorViewModel model) { var Response = HttpContext.Current.Response; Response.ContentType = "text/html"; Response.StatusCode = errorHandler.OriginalHttpStatusCode; var context = ViewRenderer.CreateController<ErrorController>().ControllerContext; var renderer = new ViewRenderer(context); string html = renderer.RenderView("~/Views/Shared/GenericError.cshtml", model); Response.Write(html); }That’s pretty sweet, because it’s now possible to use ViewRenderer just about anywhere in any ASP.NET application, not only inside of controller code. This also allows the constructor for the ViewRenderer from the last article to work without a controller context parameter, using a generic view as a base for the controller context when not passed:public ViewRenderer(ControllerContext controllerContext = null) { // Create a known controller from HttpContext if no context is passed if (controllerContext == null) { if (HttpContext.Current != null) controllerContext = CreateController<ErrorController>().ControllerContext; else throw new InvalidOperationException( "ViewRenderer must run in the context of an ASP.NET " + "Application and requires HttpContext.Current to be present."); } Context = controllerContext; }In this case I use the ErrorController class which is a generic controller instance that exists in the same assembly as my ViewRenderer class and that works just fine since ‘generically’ rendered views tend to not rely on anything from the controller other than the model which is explicitly passed.While these days most of my apps use MVC I do still have a number of generic pieces in most of these applications where Razor comes in handy. This includes modules like the above, which when they error often need to display error output. In other cases I need to generate string template output for emailing or logging data to disk. Being able to render simply render an arbitrary View to and pass in a model makes this super nice and easy at least within the context of an ASP.NET application!You can check out the updated ViewRenderer class below to render your ‘generic views’ from anywhere within your ASP.NET applications. Hope some of you find this useful.ResourcesViewRenderer Class in Westwind.Web.Mvc Library (Github)Original ViewRenderer ArticleRazor Hosting Library (GitHub)Original Razor Hosting Article© Rick Strahl, West Wind Technologies, 2005-2013Posted in ASP.NET  MVC   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

• WebLogic Server JMS WLST Script – Who is Connected To My Server

  - by james.bayer

  Ever want to know who was connected to your WebLogic Server instance for troubleshooting?  An email exchange about this topic and JMS came up this week, and I’ve heard it come up once or twice before too.  Sometimes it’s interesting or helpful to know the list of JMS clients (IP Addresses, JMS Destinations, message counts) that are connected to a particular JMS server.  This can be helpful for troubleshooting.  Tom Barnes from the WebLogic Server JMS team provided some helpful advice: The JMS connection runtime mbean has “getHostAddress”, which returns the host address of the connecting client JVM as a string.  A connection runtime can contain session runtimes, which in turn can contain consumer runtimes.  The consumer runtime, in turn has a “getDestinationName” and “getMemberDestinationName”.  I think that this means you could write a WLST script, for example, to dump all consumers, their destinations, plus their parent session’s parent connection’s host addresses.    Note that the client runtime mbeans (connection, session, and consumer) won’t necessarily be hosted on the same JVM as a destination that’s in the same cluster (client messages route from their connection host to their ultimate destination in the same cluster). Writing the Script So armed with this information, I decided to take the challenge and see if I could write a WLST script to do this.  It’s always helpful to have the WebLogic Server MBean Reference handy for activities like this.  This one is focused on JMS Consumers and I only took a subset of the information available, but it could be modified easily to do Producers.  I haven’t tried this on a more complex environment, but it works in my simple sandbox case, so it should give you the general idea. # Better to use Secure Config File approach for login as shown here http://buttso.blogspot.com/2011/02/using-secure-config-files-with-weblogic.html connect('weblogic','welcome1','t3://localhost:7001')   # Navigate to the Server Runtime and get the Server Name serverRuntime() serverName = cmo.getName()   # Multiple JMS Servers could be hosted by a single WLS server cd('JMSRuntime/' + serverName + '.jms' ) jmsServers=cmo.getJMSServers()   # Find the list of all JMSServers for this server namesOfJMSServers = '' for jmsServer in jmsServers: namesOfJMSServers = jmsServer.getName() + ' '   # Count the number of connections jmsConnections=cmo.getConnections() print str(len(jmsConnections)) + ' JMS Connections found for ' + serverName + ' with JMSServers ' + namesOfJMSServers   # Recurse the MBean tree for each connection and pull out some information about consumers for jmsConnection in jmsConnections: try: print 'JMS Connection:' print ' Host Address = ' + jmsConnection.getHostAddress() print ' ClientID = ' + str( jmsConnection.getClientID() ) print ' Sessions Current = ' + str( jmsConnection.getSessionsCurrentCount() ) jmsSessions = jmsConnection.getSessions() for jmsSession in jmsSessions: jmsConsumers = jmsSession.getConsumers() for jmsConsumer in jmsConsumers: print ' Consumer:' print ' Name = ' + jmsConsumer.getName() print ' Messages Received = ' + str(jmsConsumer.getMessagesReceivedCount()) print ' Member Destination Name = ' + jmsConsumer.getMemberDestinationName() except: print 'Error retrieving JMS Consumer Information' dumpStack() # Cleanup disconnect() exit() Example Output I expect the output to look something like this and loop through all the connections, this is just the first one: 1 JMS Connections found for AdminServer with JMSServers myJMSServer JMS Connection:   Host Address = 127.0.0.1   ClientID = None   Sessions Current = 16    Consumer:      Name = consumer40      Messages Received = 1      Member Destination Name = myJMSModule!myQueue Notice that it has the IP Address of the client.  There are 16 Sessions open because I’m using an MDB, which defaults to 16 connections, so this matches what I expect.  Let’s see what the full output actually looks like: D:\Oracle\fmw11gr1ps3\user_projects\domains\offline_domain>java weblogic.WLST d:\temp\jms.py   Initializing WebLogic Scripting Tool (WLST) ...   Welcome to WebLogic Server Administration Scripting Shell   Type help() for help on available commands   Connecting to t3://localhost:7001 with userid weblogic ...

• The standards that fail us and the intellectual bubble

  - by Jeff

  There has been a great deal of noise in the techie community about standards, and a sudden and unexplainable hate for Flash. This noise isn't coming from consumers... the countless soccer moms, teens and your weird uncle Bob, it's coming from the people who build (or at least claim to build) the stuff those consumers consume. If you could survey the position of consumers on the topic, they'd likely tell you that they just want stuff on the Web to work.The noise goes something like this: Web standards are the correct and right thing to use across the Intertubes, and anything not a part of those standards (Flash) is bad. Furthermore, the more recent noise is centered around the idea that HTML 5, along with Javascript, is the right thing to use. The arguments against Flash are, well, the truth is I haven't seen a good argument. I see anecdotal nonsense about high CPU usage and things I'd never think to check when I'm watching Piano Cat on YouTube, but these aren't arguments to me. Sure, I've seen it crash a browser a few times, but it's totally rare.But let's go back to standards. Yes, standards have played an important role in establishing the ubiquity of the Web. The protocols themselves, TCP/IP and HTTP, have been critical. HTML, which has served us well for a very long time, established an incredible foundation. Javascript did an OK job, and thanks to clever programmers writing great frameworks like JQuery, is becoming more and more useful. CSS is awful (there, I said it, I feel SO much better), and I'll never understand why it's so disconnected and different from anything else. It doesn't help that it's so widely misinterpreted by different browsers. Still, there's no question that standards are a good thing, and they've been good for the Web, consumers and publishers alike.HTML 4 has been with us for more than a decade. In Web years, that might as well be 80. HTML 5, contrary to popular belief, is not a standard, and likely won't be for many years to come. In fact, the Web hasn't really evolved at all in terms of its standards. The tools that generate the standard markup and script have, but at the end of the day, we're still living with standards that are more than ten years old. The "official" standards process has failed us.The Web evolved anyway, and did not wait for standards bodies to decide what to do next. It evolved in part because Macromedia, then Adobe, kept evolving Flash. In the earlier days, it mostly just did obnoxious splash pages, but then it started doing animation, and then rich apps as they added form input. Eventually it found its killer app: video. Now more than 95% of browsers have Flash installed. Consumers are better for it.But I'll do it one better... I'll go out on a limb and say that Flash is a standard. If it's that pervasive, I don't care what you tell me, it's a standard. Just because a company owns it doesn't mean that it's evil or not a standard. And hey, it pains me to say that as a developer, because I think the dev tools are the suck (more on that in a minute). But again, consumers don't care. They don't even pay for Flash. The bottom line is that if I put something Flash based on the Internet, it's likely that my audience will see it.And what about the speed of standards owned by a company? Look no further than Silverlight. Silverlight 2 (which I consider the "real" start to the story) came out about a year and a half ago. Now version 4 is out, and it has come a very long way in its capabilities. If you believe Riastats.com, more than half of browsers have it now. It didn't have to wait for standards bodies and nerds drafting documents, it's out today. At this rate, Silverlight will be on version 6 or 7 by the time HTML 5 is a ratified standard.Back to the noise, one of the things that has continually disappointed me about this profession is the number of people who get stuck in an intellectual bubble, color it with dogmatic principles, and completely ignore the actual marketplace where this stuff all has to live. We aren't machines; Binary thinking that forces us to choose between "open standards" and "proprietary lock-in" (the most loaded b.s. FUD term evar) isn't smart at all. The truth is that the <object> tag has allowed us to build incredible stuff on top of the old standards, and consumers have benefitted greatly. Consumer desire, capitalism, and yes, standards ratified by nerds who think about this stuff for years have all played a role in the broad adoption of the Interwebs.We could all do without the noise. At the end of the day, I'm going to build stuff for the Web that's good for my users, and I'm not going to base my decisions on a techie bubble religion. Imagine what the brilliant minds behind the noise could do for the Web if they joined me in that pursuit.

• Can't connect to Wired Network after installing 12.04

  - by ezz9

  I have installed 12.04 into a used HP Compaq DC 7100 CMT. Plugged in LAN cable into the computer and it says network disconnected. from what I understand on the things I've read, it's not getting the address right, maybe it's just a guess (hardware address 00:16:35:78:47:bb). I know the LAN cable is working I can get on the net with the old computer. (Old computer is using device MAC address; Auto eth0 00:11:11:E6:4F:FE). I have put this address into the newer HP and it shows last used (minutes ago) but no Internet sever not found. I tried the hardware address it says never. I feel and think this should be easy to fix. But I just don't know. Here is the info everyone has asked for, but they never say what I should do. sudo lshw -C network; rfkill list; cat /etc/network/interfaces; cat /etc/lsb-release; lspci -nn; lsusb; uname -a; ifconfig; route -n *-network description: ethernet interface product; NetXtreme BCM5751 Gigabit Ethernet PCI Express vendor: Broadcom Corporation physical id: 0 bus info: pci@0000:40:00.0 logical name: eth0 verson: 01 serial: 00:16:35:78:47:bb size: 100Mbit/s capacity: 1Gbit/s width: 64 bits clock: 33MHz capabilities: pm vpd msi pciexpress bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd 1000bt 1000-fd configuration: autonegotiation=on broadcast=yes driver=tg3 driverversion= 3.121 duplex=full firmware=5751-v3.29a latency=0 link=yes multicast=yes port=twi sted pair speed=100Mbit/s resources: irq:17 memory:f0400000-f040ffff auto lo iface lo inet loopback DISTRIB_ID=Ubuntu DISTRIB_RELEASE=12.04 DISTRIB_CODENAME=precise DISTRIB_DESCRIPTION= "Ubuntu 12.04 LTS" 00:00.0 host bridge [0600]: Inter Corporation 82915G/P/GV/GL/PL/910GL Memory Con troller Hub [8086:2580] (rev 04) 00.02.0 VGA compatible controller [0300]: Intel Corporation 82915G/GV/910GL inte grated Graphics Controller [8086:2582] (rev 04) 00:1c.0 PCI bridge [0604]: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) PCI Express Port 1 [8086:2660] (rev 03) 00:1c.1 PCI bridge [0604]: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) PCI Express Port 2 [8086:2662] (rev 03) 00:1d.0 USB controller [0c03]: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Fam ily) USB UHCI #1 [8086:2658] (rev 03) 00:1d.1 USB controller [0c03]: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Fam ily) USB UHCI #2 [8086:2659] (rev 03) 00:1d.2 USB controller [0c03]: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Fam ily) USB UHCI #3 [8086:265a] (rev 03) 00:1d.3 USB controller [0c03]: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Fam ily) USB UHCI #4 [8086:265b] (rev 03) 00:1d.7 USB controller [0c03]: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Fam ily) USB2 UHCI Controller [8086:265c] (rev 03) 00:1e.0 PCI bridge [0604]: Intel Corporation 82801 PCI bridge [8086:244e] (rev d 3) 00:1e.2 Multimedia audio controller [0401]: Intel Corporation 82801FB/FBM/FR/FW/ FRW (ICH6 Family) AC'97 Autio conrtroller [8086:266e] (rev 03) 00:1f.0 ISA bridge [0601]: Intel Corporation 82801FB/RF (ICH6/ICH6R) LPC Interfa ce Bridge [8086:2640] (rev 03) 00:1f.1 IDE interface [0101]: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 fami ly) IDE Controller [8086:266f] (rev 03) 00:1f.2 IDE interface [0101]: Intel Corporation 82801FB/FW (ICH6/ICH6W) SATA Con troller [8086:2651] (rev 03) 40:00.0 Ethernet controller [0200]: Broadcom Corporation NetXreme BCM5751 Gigab it Ethernet PCI Express [14e4:1677} (rev 01) Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Linux bob-desktop 3.2.0-23-generic-pae #36-Ubuntu SMP Tpr 10 22:19:09 UTC 20 12 i686 i686 i386 GNU/Linux eth0 Link encap:Ethernet HWaddr 00:16:35:78:47:bb inet6 addr: fe80::216:35ff:47bb/64 Scope:link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:2517 errors:0 dropped:0 overruns:0 frame:0 TX packets:164 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:164508 (164.5 KB) TX bytes: 40884 (40.0 KB) Interrupt:17 lo Link encap:Local loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:3290 errors:0 dropped:0 overruns:0 frame:0 TX packets:3290 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen: 0 RX bytes:267212 (267.2 KB) TX bytes: 267212 (267.2 KB) Kernel Ip routing table Destination Gateway Genmask Flags Metric Ref Use Iface ran this sudo dhclient eth0 no reply ran this ip addr 1: lo <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST ,MULTICAST ,UP ,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000 link/enter 00:16:35:78:47:BB brd ff:ff:ff:ff:ff:ff inet 169.254.7.172/16 brd 169.254.255.255 scope link eth0:avahi inet6 fe80::216:35ff:fe78:47bb/64 scope link valid_lft forever preferred_lft forever Help please.

• PeopleSoft at Alliance 2012 Executive Forum

  - by John Webb

  Guest Posting From Rebekah Jackson This week I jointed over 4,800 Higher Ed and Public Sector customers and partners in Nashville at our annual Alliance conference.   I got lost easily in the hallways of the sprawling Gaylord Opryland Hotel. I carried the resort map with me, and I would still stand for several minutes at a very confusing junction, studying the map and the signage on the walls. Hallways led off in many directions, some with elevators going down here and stairs going up there. When I took a wrong turn I would instantly feel stuck, lose my bearings, and occasionally even have to send out a call for help.    It strikes me that the theme for the Executive Forum this year outlines a less tangible but equally disorienting set of challenges that our higher education customer’s CIOs are facing: Making Decisions at the Intersection of Business Value, Strategic Investment, and Enterprise Technology. The forces acting upon higher education institutions today are not neat, straight-forward decision points, where one can glance to the right, glance to the left, and then quickly choose the best course of action. The operational, technological, and strategic factors that must be considered are complex, interrelated, messy…and the stakes are high. Michael Horn, co-author of “Disrupting Class: How Disruptive Innovation Will Change the Way the World Learns”, set the tone for the day. He introduced the model of disruptive innovation, which grew out of the research he and his colleagues have done on ‘Why Successful Organizations Fail’. Highly simplified, the pattern he shared is that things start out decentralized, take a leap to extreme centralization, and then experience progressive decentralization. Using computers as an example, we started with a slide rule, then developed the computer which centralized in the form of mainframes, and gradually decentralized to mini-computers, desktop computers, laptops, and now mobile devices. According to Michael, you have more computing power in your cell phone than existed on the planet 60 years ago, or was on the first rocket that went to the moon. Applying this pattern to Higher Education means the introduction of expensive and prestigious private universities, followed by the advent of state schools, then by community colleges, and now online education. Michael shared statistics that indicate 50% of students will be taking at least one on line course by 2014…and by some measures, that’s already the case today. The implication is that technology moves from being the backbone of the campus, the IT department’s domain, and pushes into the academic core of the institution. Innovative programs are underway at many schools like Bellevue and BYU Idaho, joined by startups and disruptive new players like the Khan Academy.   This presents both threat and opportunity for higher education institutions, and means that IT decisions cannot afford to be disconnected from the institution’s strategic plan. Subsequent sessions explored this theme.    Theo Bosnak, from Attain, discussed the model they use for assessing the complete picture of an institution’s financial health. Compounding the issue are the dramatic trends occurring in technology and the vendors that provide it. Ovum analyst Nicole Engelbert, shared her insights next and suggested that incremental changes are no longer an option, instead fundamental changes are affecting the landscape of enterprise technology in higher ed.    Nicole closed with her recommendation that institutions focus on the trends in higher education with an eye towards the strategic requirements and business value first. Technology then is the enabler.   The last presentation of the day was from Tom Fisher, Sr. Vice President of Cloud Services at Oracle. Tom runs the delivery arm of the Cloud Services group, and shared his thoughts candidly about his experiences with cloud deployments as well as key issues around managing costs and security in cloud deployments. Okay, we’ve covered a lot of ground at this point, from financials planning, business strategy, and cloud computing, with the possibility that half of the institutions in the US might not be around in their current form 10 years from now. Did I forget to mention that was raised in the morning session? Seems a little hard to believe, and yet Michael Horn made a compelling point. Apparently 100 years ago, 8 of the top 10 education institutions in the world were German. Today, the leading German school is ranked somewhere in the 40’s or 50’s. What will the landscape be 100 years from now? Will there be an institution from China, India, or Brazil in the top 10? As Nicole suggested, maybe US parents will be sending their children to schools overseas much sooner, faced with the ever-increasing costs of a US based education. Will corporations begin to view skill-based certification from an online provider as a viable alternative to a 4 year degree from an accredited institution, fundamentally altering the education industry as we know it?

• User-Defined Customer Events & their impact (FA Type Profile)

  - by Rajesh Sharma

  CC&B automatically creates field activities when a specific Customer Event takes place. This depends on the way you have setup your Field Activity Type Profiles, the templates within, and associated SP Condition(s) on the template. CC&B uses the service point type, its state and referenced customer event to determine which field activity type to generate.   Customer events available in the base product include: Cut for Non-payment (CNP) Disconnect Warning (DIWA) Reconnect for Payment (REPY) Reread (RERD) Stop Service (STOP) Start Service (STRT) Start/Stop (STSP)   Note the Field values/codes defined for each event.   CC&B comes with a flexibility to define new set of customer events. These can be defined in the Look Up - CUST_EVT_FLG. Values from the Look Up are used on the Field Activity Type Profile Template page.     So what's the use of having user-defined Customer Events? And how will the system detect such events in order to create field activity(s)?   Well, system can only detect such events when you reference a user-defined customer event on a Severance Event Type for an event type Create Field Activities.     This way you can create additional field activities of a specific field activity type for user-defined customer events.   One of our customers adopted this feature and created a user-defined customer event CNPW - Cut for Non-payment for Water Services. This event was then linked on a Field Activity Type Profile and referenced on a Severance Event - CUT FOR NON PAY-W. The associated Severance Process was configured to trigger a reconnection process if it was cancelled (done by defining a Post Cancel Algorithm). Whenever this Severance Event was executed, a specific type of Field Activity was generated for disconnection purposes. The Field Activity type was determined by the system from the Field Activity Type Profile referenced for the SP Type, SP's state and the referenced user-defined customer event. All was working well until the time when they realized that in spite of the Severance Process getting cancelled (when a payment was made); the Post Cancel Algorithm was not executed to start a Reconnection Severance Process for the purpose of generating a reconnection field activity and reconnecting the service.   Basically, the Post Cancel algorithm (if specified on a Severance Process Template) is triggered when a Severance Process gets cancelled because a credit transaction has affected/relieved a Service Agreement's debt.   So what exactly was happening? Now we come to actual question as to what is the impact in having a user-defined customer event.   System defined/base customer events are hard-coded across the entire system. There is an impact even if you remove any customer event entry from the Look Up. User-defined customer events are not recognized by the system anywhere else except in the severance process, as described above.   There are few programs which have routines to first validate the completion of disconnection field activities, which were raised as a result of customer event CNP - Cut for Non-payment in order to perform other associated actions. One such program is the Post Cancel Algorithm, referenced on a Severance Process Template, generally used to reconnect services which were disconnected from other Severance Event, specifically CNP - Cut for Non-Payment. Post cancel algorithm provided by the product - SEV POST CAN does the following (below is the algorithm's description):   This algorithm is called after a severance process has been cancelled (typically because the debt was paid and the SA is no longer eligible to be on the severance process). It checks to see if the process has a completed 'disconnect' event and, if so, starts a reconnect process using the Reconnect Severance Process Template defined in the parameter.    Notice the underlined text. This algorithm implicitly checks for Field Activities having completed status, which were generated from Severance Events as a result of CNP - Cut for Non-payment customer event.   Now if we look back to the customer's issue, we can relate that the Post Cancel algorithm was triggered, but was not able to find any 'Completed' CNP - Cut for Non-payment related field activity. And hence was not able to start a reconnection severance process. This was because a field activity was generated and completed for a customer event CNPW - Cut for Non-payment of Water Services instead.   To conclude, if you introduce new customer events that extend or simulate base customer events, the ones that are included in the base product, ensure that there is no other impact either direct or indirect to other business functions that the application has to offer.

• Upgrading Agent Controllers in Oracle Enterprise Manager Ops Center 12c

  - by S Stelting

  Oracle Enterprise Manager Ops Center 12c recently released an upgrade for Solaris Agent Controllers. In this week's blog post, we'll show you how to upgrade agent controllers. Detailed instructions about upgrading Agent Controllers are available in the product documentation here. This blog post uses an Enterprise Controller which is configured for connected mode operation. If you'd like to apply the agent update in a disconnected installation, additional instructions are available here. Step 1: Download Agent Controller Updates With a connected mode Ops Center installation, you can check for product updates at any time by selecting the Enterprise Controller from the left-hand Administration navigation tab. Select the right-hand Action link “Ops Center Downloads” to open a pop-up dialog displaying any new product updates. In this example, the Enterprise Controller has already been upgraded to the latest version (Update 1, also shown as build version 2076) so only the Agent Controller updates will appear. There are three updates available: one for Solaris 10 X86, one for Solaris 8-10 SPARC, and one for all versions of Solaris 11. Note that the last update in the screen shot is the Solaris 11 update; for details on any of the downloads, place your mouse over the information icon under the details column for a pop-up text region. Select the software to download and click the Next button to display the Ops Center license agreement. Review and click the check box to accept the license agreement, then click the Next button to begin downloading the software. The status screen shows the current download status. If desired, you can perform the downloads as a background job. Simply click the check box, then click the next button to proceed to the summary screen. The summary screen shows the updates to be downloaded as well as the current status. Clicking the Finish button will close the dialog and return to the Browser UI. The download job will continue to run in Ops Center and progress can still be viewed from the jobs menu at the bottom of the browser window. Step 2: Check the Version of Existing Agent Controllers After the download job completes, you can check the availability of agent updates as well as the current versions of your Agent Controllers from the left-hand Assets navigation tab. Select “Operating Systems” from the pull-down tab lets to display only OS assets. Next, select “Solaris” in the left-hand tab to display the Solaris assets. Finally, select the Summary tab in the center display panel to show which versions of agent controllers are installed in your data center. Notice that a few of the OS assets are not displayed in the Agent Controllers tab. Ops Center will not display OS instances which do not have an Agent Controller installation. This includes Enterprise Controllers and Proxy Controllers (unless the agent has been activated on the OS instance) and and OS instances using agentless management. For Agent Controllers which support an update, the version of agent software (in this example, 2083) appears to the right of the currently installed version. Step 3: Upgrade Your Agent Controllers If desired, you can upgrade agent controllers from the previous screen by selecting the desired systems and clicking the upgrade button. Alternatively, you can click the link “Upgrade All Agent Controllers” in the right-hand Actions menu: In either case, a pop-up dialog lets you start the upgrade process. The first screen in the dialog lets you choose the upgrade method: Ops Center provides three ways to upgrade agent controllers: Automatic Upgrade: If Agent Controllers are running on all assets, Ops Center can automatically upgrade the software to the latest version without requiring any login credentials to the system SSH using a single set of credentials: If all assets use the same login credentials, you can apply a single set to all assets for the upgrade process. The log-in credentials are the same ones used for asset discovery and management, which are stored in the Plan Management navigation tab under Credentials. SSH using individual credentials: If assets use different login credentials, you can select a different set for each asset. After selecting the upgrade method, click the Next button to proceed to the summary screen. Click the Finish button to close the pop-up dialog and start the upgrade job for the agent controllers. The upgrade job runs a series of tasks in parallel, and will upgrade all agents which have been selected. Once the job completes, the OS instances in your data center will be upgraded and running the latest version of Agent Controller software.

• Repeated disconnects on WPA PEAP network

  - by exasperated

  My school has a WPA PEAP network with GTC inner authentication. I am able to connect to the network, but once I load a website or two, the network become unresponsive (i.e. in Chromium, it gets stuck at "Sending request"), and I'm eventually disconnected.

• Intel Centrino Wireless-N 1000 Again ! Ubuntu 13.04 x64

  - by vafa

  First I have to say that I tried everything written about this concept. The problem is that it stops working randomly in 3 main forms : 1 - sometimes it disconnect from wireless network and reconnect automatically 2 - sometimes it disconnect and wont connect no matter what (needs reboot) 3 - some times it's still connected but cannot ping or surf or whatever. I already tried disabling N mod using these commands : sudo modprobe -r iwlwifi modprobe iwlwifi 11n_disable=1 (or 0, whatever) it didn't help . these are the results of lspci, sudo lshw -C network, ifconfig, iwconfig, rfkill list when it disconnected and didn't connect till reboot : ifconfig : eth0 Link encap:Ethernet HWaddr c8:0a:a9:34:65:77 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX

• Can ping device from one computer and not the other

  - by Sean Duggan

  I've recently been assigned to work on a diagnostic program done in C++ which communicates with a piece of electronic equipment. Our normal scenario involves communicating via an RS232 interface, but I've been asked to make our program work over ethernet, source code having been done in Visual Basic. After much thrashing about trying to get the code to work and continuing to get 10049 Winsock errors when I tried to connect, I tried pinging the switch. From the computer the VB program is running on, I can see the switch via ping, nslookup, tracert, and pathping (I was going down the list of programs) and I can do this via URI or IP address. From my laptop, sending the same commands fails every time. They're both using the same network cable and the same USB-to-Ethernet device (I've been swapping them between tests) but one can see the switch and the other cannot. I'm working on the programming end, but the ping results makes me think that there might be a network issue stymieing me. wry grin I'm not much of a network guy, so I'm appealing to expert assistance. Both computers are running Windows XP if that helps. The connection is to an "IP-RS8" device which then connects to our VCU-C units. Each unit is accessible via URI or IP address on the desktop computer we usually have connected to the units (it's running the older VB program that I was asked to lift the networking code from). The connection is made via a USB-to-Ethernet adapter so as to leave the regular Ethernet port available for connecting to the company network. Hmm... come to think of it, I've probably been confusing the issue, talking about pinging "the switch" rather than indicating that it's the devices. My apologies. Communication is generally done with a DLL that uses Winsock functions to make queries for data from the VCU and then to receive. I'm failing when connecting. I haven't found anything on the firewall which should block these commands, but I'll keep poking. I don't know if it's potentially relevant, but on the desktop, the adapter maps to Local Area Connection 3 while on the laptop, it consistently maps to Local Area Connection 2.

• Quick guide to Oracle IRM 11g: Server configuration

  - by Simon Thorpe

  Quick guide to Oracle IRM 11g index Welcome to the second article in this quick quide to Oracle IRM 11g. Hopefully you've just finished the first article which takes you through deploying the software onto a Linux server. This article walks you through the configuration of this new service and contains a subset of information from the official documentation and is focused on installing the server on Oracle Enterprise Linux. If you are planning to deploy on a non-Linux platform, you will need to reference the documentation for platform specific information. Contents Introduction Create IRM WebLogic Domain Starting the Admin Server and initial configuration Introduction In the previous article the database was prepared, the WebLogic Application Server installed and the files required for an IRM server installed. But we don't actually have a configured system yet. We need to now create a WebLogic Domain in which the IRM server will run, then configure some of the settings and crypography so that we can create a context and be ready to seal some content and test it all works. This article doesn't cover the configuration of SSL communication from client to server. This is quite a big topic and a separate article has been dedicated for this area. In these articles I also use the hostname, irm.company.internal to reference the IRM server and later on use the hostname irm.company.com in reference to the public facing service. Create IRM WebLogic Domain First step is creating the WebLogic domain, in a console switch to the newly created IRM installation folder as shown below and we will run the domain configuration wizard. [oracle@irm /]$ cd /oracle/middleware/Oracle_IRM/common/bin [oracle@irm bin]$ ./config.sh First thing the wizard will ask is if you wish to create a new or extend an existing domain. This guide is creating a standalone system so you should select to create a new domain. Next step is to choose what technologies from the Oracle ECM Suite you wish this domain to host. You are only interested in selecting the option "Oracle Information Rights Management". When you select this check box you will notice that it also selects "Oracle Enterprise Manager" and "Oracle JRF" as these are dependencies of the IRM server. You then need to specify where you wish to place the domain files. I usually just change the domain name from base_domain or irm_domain and leave the others with their defaults. Now the domain will have a single user initially and by default this user is called "weblogic". I usually change this account name to "sysadmin" or "administrator", but in this guide lets just accept the default. With respects to the next dialog, again for eval or dev reasons, leave the server startup mode as development. The JDK should also be automatically detected. We now need to provide details of the database. This guide is using the Oracle 11gR2 database and the settings I used can be seen in the image to the right. There is a lot of configuration that can now be done for the admin server, any managed servers and where the deployments reside. In this guide I am leaving all of these to their defaults so do not check any of the boxes. However I will on this blog be detailing later how you can go back and setup things such as automated startup of an IRM server which require changes to these default settings. But for now, lets leave it all alone and just click next. Now we are ready to install. Note that from this dialog you can scroll the left window and see there are going to be two servers created from the defaults. The AdminServer which is where you modify settings for the WebLogic Server and also hosts the Oracle Enterprise Manager for IRM which allows to monitor the IRM service performance and also make service related settings (which we shortly do below) and the IRM_server1 which hosts the actual IRM services themselves. So go right ahead and hit create, the process is pretty quick and usually under 10 minutes. When the domain creation ends, it will give you the URL to the admin server. It's worth noting this down and the URL is usually; http://irm.company.internal:7001 Starting the Admin Server and initial configuration First thing to do is to start the WebLogic Admin server and review the initial IRM server settings. In this guide we are going to run the Admin server and IRM server in console windows, in another article I will discuss running these as background services. So for now, start a console and run the Admin server by doing the following. cd /oracle/middleware/user_projects/domains/irm_domain/ ./startWebLogic.sh Wait for the server to start, you are looking for the following line to be reported in the console window. <BEA-00360><Server started in RUNNING mode> First step is configuring the IRM service via Enterprise Manager. Now that the Admin server is running you can point a browser at http://irm.company.internal:7001/em. Login with the username and password you supplied when you created the domain. In Enterprise Manager the IRM service administrator is able to make server wide configuration. However finding where to access the pages with these settings can be a bit of a challenge. After logging in on the left you'll see a tree containing elements of the Enterprise Manager farm Farm_irm_domain. Open up Content Management, then Information Rights Management and finally select the IRM node. On the right then select the IRM menu item, navigate to the Administration section and now we have four options, for now, we are just going to look at General Settings. The image on the right proves that a picture is worth a thousand words (or 113 in this case). The General Settings page allows you to set the cryptographic algorithms used for protecting sealed content. Unless you have a burning need to increase the key lengths or you need to comply to a regulation or government mandate, AES192 is a good start. You can change this later on without worry. The most important setting here we need to make is the Server URL. In this blog article I go over why this URL is so important, basically every single piece of content you protect with Oracle IRM is going to have this URL embedded in it, so if it's wrong or unresolvable, then nobody can open the secured documents. Note that in our environment we have yet to do any SSL configuration of the service. If you intend to build a server without SSL, then use http as the protocol instead of https. But I would recommend using SSL and setting this up is described in the next article. I would also probably up the device count from 1 to 3. This means that any user can retrieve rights to access content onto 3 computers at any one time. The default of 1 doesn't really make sense in development, evaluation nor even production environments and my experience is that 3 is a better number. Next step is to create the keystore for the IRM server. When a classification (called a context) is created, Oracle IRM generates a unique set of symmetric keys which are used to secure the content itself. These keys are then encrypted with a set of "wrapper" asymmetric cryptography keys which are stored externally to the server either in a Java Key Store or a HSM. These keys need to be generated and the following shows my commands and the resulting output. I have greyed out the responses from the commands so you can see the input a little easier. [oracle@irmsrv ~]$ cd /oracle/middleware/wlserver_10.3/server/bin/ [oracle@irmsrv bin]$ ./setWLSEnv.sh CLASSPATH=/oracle/middleware/patch_wls1033/profiles/default/sys_manifest_classpath/weblogic_patch.jar:/oracle/middleware/patch_ocp353/profiles/default/sys_manifest_classpath/weblogic_patch.jar:/usr/java/jdk1.6.0_18/lib/tools.jar:/oracle/middleware/wlserver_10.3/server/lib/weblogic_sp.jar:/oracle/middleware/wlserver_10.3/server/lib/weblogic.jar:/oracle/middleware/modules/features/weblogic.server.modules_10.3.3.0.jar:/oracle/middleware/wlserver_10.3/server/lib/webservices.jar:/oracle/middleware/modules/org.apache.ant_1.7.1/lib/ant-all.jar:/oracle/middleware/modules/net.sf.antcontrib_1.1.0.0_1-0b2/lib/ant-contrib.jar: PATH=/oracle/middleware/wlserver_10.3/server/bin:/oracle/middleware/modules/org.apache.ant_1.7.1/bin:/usr/java/jdk1.6.0_18/jre/bin:/usr/java/jdk1.6.0_18/bin:/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/home/oracle/bin Your environment has been set. [oracle@irmsrv bin]$ cd /oracle/middleware/user_projects/domains/irm_domain/config/fmwconfig/ [oracle@irmsrv fmwconfig]$ keytool -genkeypair -alias oracle.irm.wrap -keyalg RSA -keysize 2048 -keystore irm.jks Enter keystore password: Re-enter new password: What is your first and last name? [Unknown]: Simon Thorpe What is the name of your organizational unit? [Unknown]: Oracle What is the name of your organization? [Unknown]: Oracle What is the name of your City or Locality? [Unknown]: San Francisco What is the name of your State or Province? [Unknown]: CA What is the two-letter country code for this unit? [Unknown]: US Is CN=Simon Thorpe, OU=Oracle, O=Oracle, L=San Francisco, ST=CA, C=US correct? [no]: yes Enter key password for (RETURN if same as keystore password): At this point we now have an irm.jks in the directory /oracle/middleware/user_projects/domains/irm_domain/config/fmwconfig. The reason we store it here is this folder would be backed up as part of a domain backup. As with any cryptographic technology, DO NOT LOSE THESE KEYS OR THIS KEY STORE. Once you've sealed content against a context, the keys will be wrapped with these keys, lose these keys, and you can't get access to any secured content, pretty important. Now we've got the keys created, we need to go back to the IRM Enterprise Manager and set the location of the key store. Going back to the General Settings page in Enterprise Manager scroll down to Keystore Settings. Leave the type as JKS but change the location to; /oracle/Middleware/user_projects/domains/irm_domain/config/fmwconfig/irm.jks and hit Apply. The final step with regards to the key store is we need to tell the server what the password is for the Java Key Store so that it can be opened and the keys accessed. Once more fire up a console window and run these commands (again i've greyed out the clutter to see the commands easier). You will see dummy passed into the commands, this is because the command asks for a username, but in this instance we don't use one, hence the value dummy is passed and it isn't used. [oracle@irmsrv fmwconfig]$ cd /oracle/middleware/Oracle_IRM/common/bin/ [oracle@irmsrv bin]$ ./wlst.sh ... lots of settings fly by... Welcome to WebLogic Server Administration Scripting Shell Type help() for help on available commands wls:/offline>connect('weblogic','password','t3://irmsrv.us.oracle.com:7001') Connecting to t3://irmsrv.us.oracle.com:7001 with userid weblogic ...

The domain creation created a managed server called IRM_server1 and we need to start this, use the following commands in a new console window. cd /oracle/middleware/user_projects/domains/irm_domain/bin/ ./startManagedWebLogic.sh IRM_server1 This will start up the server in the console, unlike the Admin server, you need to provide the username and password for the service to start. Enter in your weblogic username and password when prompted. You can change this behavior by putting the password into a boot.properties file, read more about this in the WebLogic Server documentation. Once running, wait until you see the line; <Notice><WebLogicServer><BEA-000360><Server started in RUNNING mode> At this point we can now login to the Oracle IRM Management Website at the URL. http://irm.company.internal:1600/irm_rights/ The server is just configured for HTTP at the moment, no SSL involved. Just want to ensure we can get a working system up and running. You should now see a login like the image on the right and you can now login using your weblogic username and password. The next article in this guide goes over adding SSL and now testing your server by actually adding a few users, sealing some content and opening this content as a user.
