• how to create a mirror of minimum size to install Ubuntu

  - by Registered User

  I need to create an http url at my laptop to have a Ubuntu installation begin within my laptop on a Xen environment. This is how the final thing will look like http://bderzhavets.wordpress.com/2008/10/28/install-ubuntu-intrepid-server-pv-domu-at-xen-33-port-via-httpgetco-centos-52-dom0/ the host and client are both going to be my laptop, I Google d and came across apt-mirror and some other packages. I do not want to archive entire 15 GB Ubuntu repositories on my machine. It is not possible to use a CD,ISO,loop mounted disk (reason mentioned below). I have tried using netboot image on local machine which failed because if you are attempting to create a virtual machine on a hardware which does not support VT virt-manager installer necessarily needs a URL of this sort http://archive.ubuntu.com/ubuntu/dists/hardy/main/installer-i386/current/images/netboot/ any other option to create guest OS is simply grayed out. The unfortunate part is my Ethernet connections do not work when I boot with Xen-4.0 and a pv-ops Dom0 kernel from Jeremy's tree.Which is where I have to do this work.So I have to create a URL structure which is similar to Ubuntu mirrors.So how can I do this in bare minimum so that at least the console boots and once the console comes I can do some work.

• Does the google crawler really guess URL patterns and index pages that were never linked against?

  - by Dominik

  I'm experiencing problems with indexed pages which were (probably) never linked to. Here's the setup: Data-Server: Application with RESTful interface which provides the data Website A: Provides the data of (1) at http://website-a.example.com/?id=RESOURCE_ID Website B: Provides the data of (1) at http://website-b.example.com/?id=OTHER_RESOURCE_ID So the whole, non-private data is stored on (1) and the websites (2) and (3) can fetch and display this data, which is a representation of the data with additional cross-linking between those. In fact, the URL /?id=1 of website-a points to the same resource as /?id=1 of website-b. However, the resource id:1 is useless at website-b. Unfortunately, the google index for website-b now contains several links of resources belonging to website-a and vice versa. I "heard" that the google crawler tries to determine the URL-pattern (which makes sense for deciding which page should go into the index and which not) and furthermore guesses other URLs by trying different values (like "I know that id 1 exists, let's try 2, 3, 4, ..."). Is there any evidence that the google crawler really behaves that way (which I doubt). My guess is that the google crawler submitted a HTML-Form and somehow got links to those unwanted resources. I found some similar posted questions about that, including "Google webmaster central: indexing and posting false pages" [link removed] however, none of those pages give an evidence.

• Matrix.CreateBillboard centre rotation problem

  I'm having an issue with Matrix.CreateBillboard and a textured Quad where the center axis seems to be positioned incorrectly to the quad object which is rotating around a center point: Using: BasicEffect quadEffect; Drawing the quad shape: Left = Vector3.Cross(Normal, Up); Vector3 uppercenter = (Up * height / 2) + origin; LowerLeft = uppercenter + (Left * width / 2); LowerRight = uppercenter - (Left * width / 2); UpperLeft = LowerLeft - (Up * height); UpperRight = LowerRight - (Up * height); Where height and width are float values passed in (it draws a square) Draw method: quadEffect.View = camera.view; quadEffect.Projection = camera.projection; quadEffect.World = Matrix.CreateBillboard(Origin, camera.cameraPosition, Vector3.Up, camera.cameraDirection); GraphicsDevice.BlendState = BlendState.Additive; foreach (EffectPass pass in quadEffect.CurrentTechnique.Passes) { pass.Apply(); GraphicsDevice.DrawUserIndexedPrimitives <VertexPositionNormalTexture>( PrimitiveType.TriangleList, Vertices, 0, 4, Indexes, 0, 2); } GraphicsDevice.BlendState = BlendState.Opaque; In the screenshots below i draw the image at Vector3(32f, 0f, 32f) The screenshots below show you the position of the quad in relation to the red cross.

• Why doesn't Firefox cache my images and CSS

• Wordpress blog penalized by Google search - what's wrong?

  - by pawelbrodzinski

  I have a blog (http://blog.brodzinski.com), which is wordpress.org blog with pretty popular Thesis theme with almost no other customizations. Some time ago it was penalized by Google search - it simply stopped appearing in search results even for search terms it used to be top result, like my name - Pawel Brodzinski - which isn't anything close to popular search term. To be exact the site has been penalized on Nov 18. It started popping up in search result on Dec 23 but only for a few days. Since Dec 27 it is out again. I know Google guidelines and I'm not aware to break any of them. I submitted reconsideration request after I noticed penalty. It was proceeded and there was no change whatsoever (no surprise as it seems the site was penalized again). I checked diagnostics in webmaster tools and neither any malware was detected nor any strange search terms popped up. I read related threads on Google webmasters forum but found none of solutions working for me. I posted a thread on Google webmasters forum (http://www.google.com/support/forum/p/Webmasters/thread?tid=546339f49d4a03bc&hl=en) and the only answer I got was to check for duplicate content. Well, there is some duplicate content published on the web but it is true for vast majority of blogs and it doesn't seem to be a reason for a penalty. Also before Dec 27 I was able to remove duplicate content from a couple of sites which were republishing my feed but this doesn't change the situation - the site was penalized again. The problem is I have no idea what can be wrong with the website or how to find it out. To make the problem worse I'm no webmaster, I just run a wordpress blog, which supposed to be easy.

• Problems with microphone and network

  - by AnoonymoouS

  Hello... very good day everybody! I'm having some problems regarding the Ubuntu 12.4.01 LTS. For this reason, cordially i ask everyone's help. Such problems can be summed up in network (01) and audio (02)! 01) I can not set a DSL network settings in the "upper bar" (on side the clock). When i create the connection, the system says that the cables modem are disconnected! I can only use the internet if i set up a connection at terminal through the command "pppoeconf". Follows the print screen of what i mentioned above:. http://i.imgur.com/8nTrF.png Obs.: Note that even after the connection "created", it does not appear there! 02) The sound is reproduced; however, can not be captured! I can not make recordings, obviously i can't use the microphone. I believe that something is giving interference or the settings are wrong! Follows the video of what i mentioned above:. http://dl.dropbox.com/u/41085750/Projeto%20Padr%C3%A3o.mp4 Obs.: I'm listening to music, so that interference errors may appear in the video. By kindness; who can help me... help me! I sought help at various sites and forums but unfortunately, i did not get success. I wait anxiously for a direction. Regards, Anoonymoous.

• Monitoring Visual Studio 2010 Performance Problems

  - by TATWORTH

  At http://visualstudiogallery.msdn.microsoft.com/fa85b17d-3df2-49b1-bee6-71527ffef441, Microsoft have provided a tool for Visual Studio to provide reports on Visual Studio 2010 performance problems. The use of it has been discussed at http://blogs.msdn.com/b/visualstudio/archive/2011/05/02/perfwatson.aspx as follows: "Would you like Visual Studio 2010 to be even faster? Would you like any performance issue you see to be  reported automatically without any hassle? Well now you can, with the new Visual Studio PerfWatson extension! Install this extension and help us deliver a faster Visual Studio experience. We’re constantly working to improve the performance of Visual Studio and take feedback about it very seriously. Our investigations into these issues have found that there are a variety of scenarios where a long running task can cause the UI thread to hang or become unresponsive. Visual Studio PerfWatson is a low overhead telemetry system that helps us capture these instances of UI unresponsiveness and report them back to Microsoft automatically and anonymously. We then use this data to drive performance improvements that make Visual Studio faster." Now instead of complaining you too can help Microsoft locate and fix performance problems with Visual Studio 2010. The requirements are: "Following are the pre-requisites for installing Visual Studio PerfWatson: Windows Vista/2008/2008 R2/7 (Note: PerfWatson is not supported for Windows XP) Visual Studio 2010 SP1 (Professional, Premium, or Ultimate)"

• Creating a backup - Rsync - Connection refused (111)

  - by pablofiumara

  I am trying to create a backup of my website for free. I just want to have a backup of my website, including not only all files and the configuration but also the databases. I mean, a full backup. If it can be done automatically, it would be better. I feel there are better ways than using the cpanel to achieve that (actually, I believe sometimes web hosters does not have any cpanel). I read the following on how to do it: Automatically mirror the entire contents and configuration of your main server to a secondary backup server on a completely separate network in a different data centre. Use RSync, FXP, cPanel voodoo, or whatever method you wish to automate syncing. That is why I installed Rsync Daemon which is an alternative to SSH for remote backups. I configured it but the test went wrong. The terminal is showing me this: pablofiumara@pablofiumara-Lenovo-G470:~$ sudo rsync [email protected]::share [sudo] password for pablofiumara: rsync: failed to connect to pablofiumara.com (50.87.147.75): Connection refused (111) rsync error: error in socket IO (code 10) at clientserver.c(122) [Receiver=3.0.9] pablofiumara@pablofiumara-Lenovo-G470:~$ sudo rsync [email protected]::share failed to connect to 50.87.147.7 (50.87.147.7): Connection refused (111) rsync error: error in socket IO (code 10) at clientserver.c(122) [Receiver=3.0.9] What should I do? Is there a better or easier way to achieve what I wish (I mentioned this in the first paragraph)?

• Facebook shared links not opening (Redirecting correctly) [on hold]

  - by Hammad

  I have been in a problem and after hours of searching find nothing useful to counter it. I have a website, and that website has RSS feed attached to facebook page. As I post the content to website it also appears on facebook page. But I have people complaining on my page that my posts don't open when they click the link to read the details. Since I am a Chrome user and didn't notice this happening for months. But as I checked it through firefox and Internet Explorer, I found the links shared actually don't open with these browswers. They only work in Chrome, means they are properly redirected in chrome browser and not in firefox and IE. Whenever I click on links of posts on my page through IE or firefox the url does not simply redirect to my website and I get to see nothing as if I am not connecting to Internet. When examining URL I see this: http://www.facebook.com/l.php?u=http%3A%2F%2Fbit.ly%2F112NVO9&h=EAQHDgTUv&s=1 Which shows that facebook is not redirecting the links properly. Moreover I also use link shortening service bit.ly to shorten my shared links. I have checked same problem exists even if I don't shorten my links. And I checked I am not alone, even the tech giant website mashable.com links also don't open in IE and FF from facebook, they only open in Chrome. From mobile phone the links don't open (redirected properly) even in chrome. Can anyone tell me what is the issue? Nothing much is written about it on Internet as no once has faced this problem. P.S: I have checked from different systems, the problem persists.

• ExaLogic virtual datacenter live at Qualogy

  - by JuergenKress

  Just a quick post to celebrate another siginificant milestone for Exalogic! After a few days of preparations and some hard work we succeeded in upgrading our Exalogic quarterrack to the newly released Elastic Cloud version 2.0.1.1.0. This version was just recently released on July 25th. This new version turns your Exalogic into a virtual datacenter with many very neat cloud provisioning capabilities. There are many more possibilities in this version to provide strict network and vServer group isolation where needed and it helps you manage multitenancy and delegate your cloud administration. How did we fare? Apart from some small inconveniences and minor issues I can tell you it all went remarkably well, provided you do proper homework on the prerequisite requirements and you stick to the instructions all the way through (there’s some 37 steps to cover). We as a specialized Exalogic partner had early access to this version and did some early adopter work. As a customer this is all done for you as Oracle will deliver a new Exalogic with this version from the factory if you so desire, or upgrade your current ones. O fcourse, Qualogy can do this for you as well! Interested contact the Qualogy team [email protected]!

  - by Bob Rhubart

  Oracle 11gR2 RAC on Software Defined Network (SDN) | Gilbert Stan "The SDN [software defined network] idea is to separate the control plane and the data plane in networking and to virtualize networking the same way we have virtualized servers," explains Gil Standen. "This is an idea whose time has come because VMs and vmotion have created all kinds of problems with how to tell networking equipment that a VM has moved and to preserve connectivity to VPN end points, preserve IP, etc." H/T to Oracle ACE Director Tim Hall for the recommendation. ServerSent-Events on WebLogic Server | Steve Buttons "The HTML5 ServerSent-Event model provides a mechanism to allow browser clients to establish a uni-directional communication path to a server, where the server is then able to push messages to the browser at any point in time," explains Steve "Buttso" Buttons. Focus on Architects and Architecture This handy guide for sessions and other activities at Oracle OpenWorld 2012 focuses on IT architecture in all its many facets and permutations. Operating System Set-up for WebLogic Server | Rene van Wijk Oracle ACE Rene van Wijk shows you how to set-up an operating system for WebLogic Server.

• Eclipse Java Code Formatter in NetBeans Plugin Manager

  - by Geertjan

  Great news for Eclipse refugees everywhere. Benno Markiewicz forked the Eclipse formatter plugin that I blogged about sometime ago (here and here)... and he fixed many bugs, while also adding new features. It's a handy plugin when you're (a) switching from Eclipse to NetBeans and want to continue using your old formatting rules and (b) working in a polyglot IDE team, i.e., now the formatting rules defined in Eclipse can be imported into NetBeans IDE and everyone will happily be able to conform to the same set of formatting standards. And now you can get it directly from Tools | Plugins in NetBeans IDE 7.4: News from Benno on the plugin, received from him today: The plugin is verified by the NetBeans community and available in the Plugin Manager in NetBeans IDE 7.4 (as shown above) and also at the NetBeans Plugin Portal here, where you can also read quite some info about the plugin:  http://plugins.netbeans.org/plugin/50877/eclipse-code-formatter-for-java The issue with empty undo buffer was solved with the help of junichi11: https://github.com/markiewb/eclipsecodeformatter_for_netbeans/issues/18 The issue with the lost breakpoints remains unsolved and there was no further feedback. That is the main reason why the save action isn't activated by default. See also the open known issues at https://github.com/markiewb/eclipsecodeformatter_for_netbeans/issues?state=open Features are as follows:  Global configuration and project specific configuration.  On save action, which is disabled by default. Show the used formatter as a notification, which is enabled by default.  Finally, Benno testifies to the usefulness, stability, and reliability of the plugin: I use the Eclipse formatter provided by this plugin every day at work. Before I commit, I format the sources. It works and that's it. I am pleased with it. Here's where the Eclipse formatter is defined globally in Tools | Options: And here is per-project configuration, i.e., use the Project Properties dialog of any project to override the global settings:  Interested to hear from anyone who tries the plugin and has any feedback of any kind!

• Large enterprise application - clients wish to use duplicate e-mails addresses?

  - by Alex Key

  I'd like to know people's opinions, reactions to clients and technical work arounds (if applicable), to the issue of an enterprise application where a client wishes to use duplicate e-mail addresses? To clarify, when I say duplicate e-mail addresses I mean within the same client system, having multiple users that have the same e-mail address. So not just using generic e-mail addresses but using the e-mail address of another user. e.g. Bob Jenkins: bjenkins@myorg.com James Jeffery: bjenkins@myorg.com Context To give this some further context, in the e-learning sector it is common that although all staff in an organisation must complete e-learning - they may not have their own e-mail address so they choose to use their managers e-mail address. Albeit against good practice in public sites... it's a requirement we've over and over again where an organisation is split between office based staff and perhaps e.g. staff in a warehouse. Where problem lies Mr Steak, good point, the problem lies in password resets and perhaps in situations where semi-personal information could be sent (not confidential enough to worry about the insecurities of email). Perhaps reminders for specific system actions, which would be confusing for the unintended party to see (if perhaps misreading the e-mail's intended recipient) Possible solutions System knowing the difference between a "for the attention of" and direct to the person e-mails, including this in the body text. Using alternative communication such as SMS Simply not having e-mails sent to people who are not the intended recipient. Providing an e-mail service ourselfs (not really viable for a corporate IT dept) Thoughts?

• HTML5 media loading sometimes suspends or aborts: misconfigured Apache?

  - by Joan Botella

  Recently, some code that has been working fine for months started to run unexpectedly. That code is just a media files loading JavaScript function, that uses jQuery. It's pretty long, but in essence it is like this: var $audio=$('<audio>'); $audio.on('canplaythrough',function(e){ $audio[0].play(); }); $audio.attr('src','song.ogg'); Basically, the file only loads sometimes, and sometimes stops loading with a suspend or even an abort event. I have uploaded a little testing HTML to http://www.joanbotella.com/tests/loading , where you can see what's happening. You can download the test files from http://www.joanbotella.com/tests/loading/loadingTest.zip for local testing. I have just checked that opening the test index.html file directly into Firefox, and not through my localhost Apache server, makes the audio files perfectly playable. So, I assume, my hosting and I have the Apache server misconfigured for serving media files. My software versions are: Apache 2.2.22-1ubuntu1.7 , Mozilla Firefox 31.0 , Chromium 36.0.1985.125 and jQuery 1.11.0. Can you help me? Thanks in advance!

• htaccess correct, Apache logs still showing the evil visitors with 200 code

  I hope someone can help me. Please take a look at the following snippet of Apache logs: 95-169-172-157.evilvisitor.com - - [12/Nov/2012:09:46:02 -0500] "GET /the-page-I-dont-want-to-deliver.html HTTP/1.1" 200 9171 "http://hackers.ru/" "Mozilla/4.0 (MSIE 6.0; Windows NT 5.1; Search)" I have the following included in my .htaccess for the root directory of the website and there are no other .htaccess files anywhere that would affect this: RewriteEngine On Options +FollowSymLinks ServerSignature Off ErrorDocument 403 "Nothing Interesting Here" order allow,deny deny from evilvisitor.com deny from hackers.ru deny from anonymouse.org allow from all I also have GeoIP functioning properly and have this included there: #for stuff from different countries RewriteCond %{ENV:GEOIP_COUNTRY_CODE} ^(UA|TR|RU|RO|LV|CZ|IR|HR|KR|TW|NO|NL|NO|IL|SE) RewriteRule ^(.*)$ [R=F,L I know this works because whenever I attempt to access the website from a proxy in say, Spain, I get the error message. I also know it works because when accessing the website from anonymouse.org, the proper error code page is displayed.

• Data Source Security Part 3

  - by Steve Felts

  In part one, I introduced the security features and talked about the default behavior.  In part two, I defined the two major approaches to security credentials: directly using database credentials and mapping WLS user credentials to database credentials.  Now it's time to get down to a couple of the security options (each of which can use database credentials or WLS credentials). Set Client Identifier on Connection When "Set Client Identifier" is enabled on the data source, a client property is associated with the connection.  The underlying SQL user remains unchanged for the life of the connection but the client value can change.  This information can be used for accounting, auditing, or debugging.  The client property is based on either the WebLogic user mapped to a database user using the credential map Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} or is the database user parameter directly from the getConnection() method, based on the “use database credentials” setting described earlier. To enable this feature, select “Set Client ID On Connection” in the Console.  See "Enable Set Client ID On Connection for a JDBC data source" http://docs.oracle.com/cd/E24329_01/apirefs.1211/e24401/taskhelp/jdbc/jdbc_datasources/EnableCredentialMapping.html in Oracle WebLogic Server Administration Console Help. The Set Client Identifier feature is only available for use with the Oracle thin driver and the IBM DB2 driver, based on the following interfaces. For pre-Oracle 12c, oracle.jdbc.OracleConnection.setClientIdentifier(client) is used.  See http://docs.oracle.com/cd/B28359_01/network.111/b28531/authentication.htm#i1009003 for more information about how to use this for auditing and debugging.   You can get the value using getClientIdentifier()  from the driver.  To get back the value from the database as part of a SQL query, use a statement like the following. “select sys_context('USERENV','CLIENT_IDENTIFIER') from DUAL”. Starting in Oracle 12c, java.sql.Connection.setClientInfo(“OCSID.CLIENTID", client) is used.  This is a JDBC standard API, although the property values are proprietary.  A problem with setClientIdentifier usage is that there are pieces of the Oracle technology stack that set and depend on this value.  If application code also sets this value, it can cause problems. This has been addressed with setClientInfo by making use of this method a privileged operation. A well-managed container can restrict the Java security policy grants to specific namespaces and code bases, and protect the container from out-of-control user code. When running with the Java security manager, permission must be granted in the Java security policy file for permission "oracle.jdbc.OracleSQLPermission" "clientInfo.OCSID.CLIENTID"; Using the name “OCSID.CLIENTID" allows for upward compatible use of “select sys_context('USERENV','CLIENT_IDENTIFIER') from DUAL” or use the JDBC standard API java.sql.getClientInfo(“OCSID.CLIENTID") to retrieve the value. This value in the Oracle USERENV context can be used to drive the Oracle Virtual Private Database (VPD) feature to create security policies to control database access at the row and column level. Essentially, Oracle Virtual Private Database adds a dynamic WHERE clause to a SQL statement that is issued against the table, view, or synonym to which an Oracle Virtual Private Database security policy was applied.  See Using Oracle Virtual Private Database to Control Data Access http://docs.oracle.com/cd/B28359_01/network.111/b28531/vpd.htm for more information about VPD.  Using this data source feature means that no programming is needed on the WLS side to set this context; it is set and cleared by the WLS data source code. For the IBM DB2 driver, com.ibm.db2.jcc.DB2Connection.setDB2ClientUser(client) is used for older releases (prior to version 9.5).  This specifies the current client user name for the connection. Note that the current client user name can change during a connection (unlike the user).  This value is also available in the CURRENT CLIENT_USERID special register.  You can select it using a statement like “select CURRENT CLIENT_USERID from SYSIBM.SYSTABLES”. When running the IBM DB2 driver with JDBC 4.0 (starting with version 9.5), java.sql.Connection.setClientInfo(“ClientUser”, client) is used.  You can retrieve the value using java.sql.Connection.getClientInfo(“ClientUser”) instead of the DB2 proprietary API (even if set setDB2ClientUser()).  Oracle Proxy Session Oracle proxy authentication allows one JDBC connection to act as a proxy for multiple (serial) light-weight user connections to an Oracle database with the thin driver.  You can configure a WebLogic data source to allow a client to connect to a database through an application server as a proxy user. The client authenticates with the application server and the application server authenticates with the Oracle database. This allows the client's user name to be maintained on the connection with the database. Use the following steps to configure proxy authentication on a connection to an Oracle database. 1. If you have not yet done so, create the necessary database users. 2. On the Oracle database, provide CONNECT THROUGH privileges. For example: SQL> ALTER USER connectionuser GRANT CONNECT THROUGH dbuser; where “connectionuser” is the name of the application user to be authenticated and “dbuser” is an Oracle database user. 3. Create a generic or GridLink data source and set the user to the value of dbuser. 4a. To use WLS credentials, create an entry in the credential map that maps the value of wlsuser to the value of dbuser, as described earlier.   4b. To use database credentials, enable “Use Database Credentials”, as described earlier. 5. Enable Oracle Proxy Authentication, see "Configure Oracle parameters" in Oracle WebLogic Server Administration Console Help. 6. Log on to a WebLogic Server instance using the value of wlsuser or dbuser. 6. Get a connection using getConnection(username, password).  The credentials are based on either the WebLogic user that is mapped to a database user or the database user directly, based on the “use database credentials” setting.  You can see the current user and proxy user by executing: “select user, sys_context('USERENV','PROXY_USER') from DUAL". Note: getConnection fails if “Use Database Credentials” is not enabled and the value of the user/password is not valid for a WebLogic Server user.  Conversely, it fails if “Use Database Credentials” is enabled and the value of the user/password is not valid for a database user. A proxy session is opened on the connection based on the user each time a connection request is made on the pool. The proxy session is closed when the connection is returned to the pool.  Opening or closing a proxy session has the following impact on JDBC objects. - Closes any existing statements (including result sets) from the original connection. - Clears the WebLogic Server statement cache. - Clears the client identifier, if set. -The WebLogic Server test statement for a connection is recreated for every proxy session. These behaviors may impact applications that share a connection across instances and expect some state to be associated with the connection. Oracle proxy session is also implicitly enabled when use-database-credentials is enabled and getConnection(user, password) is called,starting in WLS Release 10.3.6.  Remember that this only works when using the Oracle thin driver. To summarize, the definition of oracle-proxy-session is as follows. - If proxy authentication is enabled and identity based pooling is also enabled, it is an error. - If a user is specified on getConnection() and identity-based-connection-pooling-enabled is false, then oracle-proxy-session is treated as true implicitly (it can also be explicitly true). - If a user is specified on getConnection() and identity-based-connection-pooling-enabled is true, then oracle-proxy-session is treated as false.

• Resolution changes when using switch

  - by Edward D

  So, the "real" resolution of my monitor is 1024x768. That's what I'd use on my docked Windows laptop, and what I'd use on my Xubuntu desktop connected directly. When I connect a switch, to switch between the two, however, the ubuntu machine's resolution changes. Everything's still proportional, and it still thinks it's doing 1024x768, but the icons and fonts appear larger. Not 800x600 larger, but still big. When I used Xubuntu Precise, I created an xorg.conf file to set a resolution of 1280x1024 which made it look the way it does without the switch ... as a workaround. When I upgraded to Trusty, I lost this. I tried to re-create it, but doesn't seem to load my file. Ideally, I'd like to correct the original problem, but I'd settle for being able to up the resolution. I searched for a while, and tried to do it, but I'm giving up ... please help me out.

• How to diagnose Ubuntu CPU spikes / IO wait?

  - by Jeff Welling

  I'm using Ubuntu and every couple minutes it goes unresponsive for a half second to a full second, which isn't normally a problem but makes trying to code extremely frustrating when your trying to hit backspace or navigate the code and nothing is happening. The problem is, the freezes are so brief that top doesn't have time to show me what is spiking the CPU (assuming something is, but I don't know what else could cause this). Does anyone know how to troubleshoot this performance issue? Edit: I've tried login in with Gnome Classic (No Effects) instead of Unity but it still freezes up every once in awhile. Edit: The CPU graph doesn't seem to be showing any actual spikes so it seems you were right and my original diagnosis of CPU spikes being the problem was incorrect, I now suspect IO wait. I don't recall this happening for the brief few weeks I had Windows 7 Starter running on it though, which leads me to believe it isn't (just?) the hardware.. is there anything I can tweak to improve this? I'm using an Acer Aspire One D257, with Ubuntu 11.10. Edit: Output of dmesg is at http://paste.ubuntu.com/1060054/ and kern.log is at http://paste.ubuntu.com/1060055/
