• Ubuntu 12.04 installation problem

  - by LittleLego

  Okay, at the beginning of the installation, it went well. My laptop is connected to power source, the internet, I have also checked the boxes "install updates while installation", "install third party plugin". After inputting location, keyboard layout info and user's details and password, the installation took place. But after 3/4 of the installation, it stopped, right above the progress bar, it displayed "installing system", I clicked on the arrow below it, the terminal-like screen also stopped carrying out the process. I then clicked on the "Skip" button, nothing happens. I thought it was the problem of my laptop, then I did another fresh installation, same thing happened. The terminal-like screen was showing some different words. But it's not an error message, just some installation info. Does anyone have valuable solution to this problem?

• SharePoint.DesignFactory.ContentFiles–building WCM sites

  - by svdoever

  One of the use cases where we use the SharePoint.DesignFactory.ContentFiles tooling is in building SharePoint Publishing (WCM) solutions for SharePoint 2007, SharePoint 2010 and Office365. Publishing solutions are often solutions that have one instance, the publishing site (possibly with subsites), that in most cases need to go through DTAP. If you dissect a publishing site, in most case you have the following findings: The publishing site spans a site collection The branding of the site is specified in the root site, because: Master pages live in the root site (/_catalogs/masterpage) Page layouts live in the root site (/_catalogs/masterpage) The style library lives in the root site ( /Style Library) and contains images, css, javascript, xslt transformations for your CQWP’s, … Preconfigured web parts live in the root site (/_catalogs/wp) The root site and subsites contains a document library called Pages (or your language-specific version of it) containing publishing pages using the page layouts and master pages The site collection contains content types, fields and lists When using the SharePoint.DesignFactory.ContentFiles tooling it is very easy to create, test, package and deploy the artifacts that can be uploaded to the SharePoint content database. This can be done in a fast and simple way without the need to create and deploy WSP packages. If we look at the above list of artifacts we can use SharePoint.DesignFactory.ContentFiles for master pages, page layouts, the style library, web part configurations, and initial publishing pages (these are normally made through the SharePoint web UI). Some artifacts like content types, fields and lists in the above list can NOT be handled by SharePoint.DesignFactory.ContentFiles, because they can’t be uploaded to the SharePoint content database. The good thing is that these artifacts are the artifacts that don’t change that much in the development of a SharePoint Publishing solution. There are however multiple ways to create these artifacts: Use paper script: create them manually in each of the environments based on documentation Automate the creation of the artifacts using (PowerShell) script Develop a WSP package to create these artifacts I’m not a big fan of the third option (see my blog post Thoughts on building deployable and updatable SharePoint solutions). It is a lot of work to create content types, fields and list definitions using all kind of XML files, and it is not allowed to modify these artifacts when in use. I know… SharePoint 2010 has some content type upgrade possibilities, but I think it is just too cumbersome. The first option has the problem that content types and fields get ID’s, and that these ID’s must be used by the metadata on for example page layouts. No problem for SharePoint.DesignFactory.ContentFiles, because it supports deploy-time resolving of these ID’s using PowerShell. For example consider the following metadata definition for the page layout contactpage-wcm.aspx.properties.ps1: Metadata page layout # This script must return a hashtable @{ name=value; ... } of field name-value pairs # for the content file that this script applies to. # On deployment to SharePoint, these values are written as fields in the corresponding list item (if any) # Note that fields must exist; they can be updated but not created or deleted. # This script is called right after the file is deployed to SharePoint.   # You can use the script parameters and arbitrary PowerShell code to interact with SharePoint. # e.g. to calculate properties and values at deployment time.   param([string]$SourcePath, [string]$RelativeUrl, $Context) @{     "ContentTypeId" = $Context.GetContentTypeID('GeneralPage');     "MasterPageDescription" = "Cloud Aviator Contact pagelayout (wcm - don't use)";     "PublishingHidden" = "1";     "PublishingAssociatedContentType" = $Context.GetAssociatedContentTypeInfo('GeneralPage') } The PowerShell functions GetContentTypeID and GetAssociatedContentTypeInfo can at deploy-time resolve the required information from the server we are deploying to. I personally prefer the second option: automate creation through PowerShell, because there are PowerShell scripts available to export content types and fields. An example project structure for a typical SharePoint WCM site looks like: Note that this project uses DualLayout. So if you build Publishing sites using SharePoint, checkout out the completely free SharePoint.DesignFactory.ContentFiles tooling and start flying!

  - by tinuz

  I installed the MATE desktop using this manual http://www.unixmen.com/linux-tutorials/linux-distributions/linux-distributions4-ubuntu/1975-install-linuxmint12-extensions-mate-a-mgse-in-ubuntu-1110- but now i can't open my Ubuntu Software Center and can't open the settings from the update manager.

• SEO: Nested List vs List, Split Over Divs vs Definition List

  - by Jon P

  From an SEO perspective which, if any, is better: Option 1: Nested lists with h2 tags <ul id="mainpoints"> <li><h2>Powerful Analysis</h2> <ul> <li>Charting and indicators</li> <li>Daily trading signals</li> <li>Company health checks</li> </ul> </li> <li><h2>World Market Data</h2> <ul> [List Items removed for brevity] </ul> </li> <li><h2>Daily Market Data</h2> <ul> [List Items removed for brevity] </ul> </li> </ul> Option 2: Divs with h2 and lists <div id="mainpoints"> <div> <h2>Powerful Analysis</h2> <ul> <li>Charting and indicators</li> <li>Daily trading signals</li> <li>Company health checks</li> </ul> </div> <div> <h2>World Market Data</h2> <ul> [List Items removed for brevity] </ul> </div> <div> <h2>Daily Market Data</h2> <ul> [List Items removed for brevity] </ul> </div> </div> Option 3: Definition List <dl id="mainpoints"> <dt>Powerful Analysis</dt> <dd>- Charting and indicators</dd> <dd>- Daily trading signals</dd> <dd>- Company health checks</dd> <dt>World Market Data</dt> [List Items removed for brevity] <dt>Daily Market Data</dt> [List Items removed for brevity] </dl> My instincts tell me that semanticaly the pure list options (1 & 3) are the best and that h2 may be more SEO friendly (1 & 2) which would point to option 1 as being the best option. I do love the lean makeup of the definition list but will I take an SEO hit by losing the h2 tags? Before anyone asks, h2 is not valid markup in a dt tag. Are my instincts right with a nested list being the way to go?

• Upgrading Fusion Middleware 11.1.1.x to 11.1.1.4

  - by James Taylor

  This is a follow on from my previous post where we upgraded 11.1.1.2 to 11.1.1.3. The instructions I provide here will work for Fusion Middleware 11.1.1.2 and 11.1.1.3 wanting to upgrade to 11.1.1.4. In this example I’m just upgrading SOA Suite on OEL 64bit but the steps will be the same, some of the downloads may be different based on your environment. To upgrade to 11.1.1.4 you need to have access to http://support.oracle.com as this is where the downloads reside. Oracle provides 11.1.1.4 as a standalone download so you can do a fresh install if required using OTN downloads (http://www.oracle.com/technetwork/indexes/downloads/index.html). The high level steps to upgrade are as follows: Download software Shutdown you SOA Environment Upgrade WLS to 11.1.1.4 Upgrade SOA Suite to 11.1.1.4 Upgrade OSB to 11.1.1.4 Upgrade MSD Schemas Identify the downloads you require for your install. You will need the WebLogic Server Upgrade and the additional product downloads. If you are using 64bit then use the generic version. The downloads are found from the following location - http://download.oracle.com/docs/html/E18749_01/download_readme.htm#BABDDIIC For the purpose of this post I downloaded the following patches 11060985 – WLS Server Generic 11060960 – SOA Suite 11061005 – OSB Suite You must also download the 11.1.1.4 RCU tool to upgrade the DB schemas. It is available via OTN, or, Oracle Support, I have provided the link from Oracle Support.  11060956 – RCU Make sure you have set the Java executable in your PATH e.g. export PATH=$JAVA_HOME/bin:$PATH  Make sure all your WebLogic environment has been shut down before performing the upgrade. Extract the WLS patch 11060985 to a temporary directory and start the installer java –jar wls1034_upgrade_generic.jar Please note if you are not running 64BIT then the upgrade executable will be just a bin file which you can execute directly. Chose the right Oracle home for your WebLogic Server install. In the Register for Security Updates you can enter your details or just click Next. If you do not enter details confirm that you don’t want to receive these updates Select the products you want to upgrade and select next. It is recommended that you accept the defaults. Confirm the directories that will be upgraded Upgrade of WLS ahs been completed   Extract your both SOA downloads to a temporary directory and run the installer found in Disk1 ./runInstaller -jreLoc /java/jdk1.6.0_20/jre Please note that the java location and version may be different for your environment Skip the Software Updates Ensure your system meets the prerequisites Set the Oracle home for your SOA install. You will be asked to confirm that you want to upgrade, click Yes Choose your application server. Since you are upgrading from 11.1.1.x you will be on WebLogic Start the Install Installation Upgrade of SOA Suite completed accept the default to finish.   In my environment I have OSB installed so I need to upgrade this next. If you don’t have SOA Suite you can go straight to completing the DB Schema updates at Step 24.  Extract the OSB upgrade files to a temporary directory and execute the installer found in the Disk1 folder. ./runInstaller -jreLoc /java/jdk1.6.0_20/jre Skip the software updates Select the Oracle home for your environment Accept the warning to continue the upgrade Point to the location of your WebLogic Server installation Install the OSB upgrade Upgrade has been completed accept the defaults Change directory to $MW_HOME/oracle_common/bin where the Patch Set Assistant is installed Execute the following command to update the MDS schema. Please not for my examples I have the context set to DEV. your may be different. This means that all my schemas are prefixed by DEV. ./psa -dbType Oracle -dbConnectString 'localhost:1521:xe' -dbaUserName sys -schemaUserName DEV_MDS You will be asked you passwords for sys and the schema Enter the database administrator password for "sys": Enter the schema password for schema user "DEV_MDS": Change directory to $MW_HOME/Oracle_SOA1/bin to where the Patch Set Assistant is installed for SOA Suite. Execute the following command to update the SOA and BAM schemas ./psa -dbType Oracle -dbConnectString 'localhost:1521:xe' -dbaUserName sys -schemaUserName DEV_SOAINFRA   To check that you have the installed correctly run the following SQL as sysdba. SELECT owner, version, status FROM schema_version_registry; OWNER                          VERSION                        STATUS ------------------------------ ------------------------------ ----------- DEV_MDS                        11.1.1.4.0                     VALID DEV_SOAINFRA                   11.1.1.4.0                     VALID Don’t stress if the versions are not all sitting at version 11.1.1.4 as not all schemas need to be updated. The key ones are MDS and SOAINFRA

• New security options in UCM Patch Set 3

  - by kyle.hatlestad

  While the Patch Set 3 (PS3) release was mostly focused on bug fixes and such, some new features sneaked in there. One of those new features is to the security options. In 10gR3 and prior versions, UCM had a component called Collaboration Manager which allowed for project folders to be created and groups of users assigned as members to collaborate on documents. With this component came access control lists (ACL) for content and folders. Users could assign specific security rights on each and every document and folder within a project. And it was even possible to enable these ACL's without having the Collaboration Manager component enabled (see technote# 603148.1). When 11g came out, Collaboration Manager was no longer available. But the configuration settings to turn on ACLs were still there. Well, in PS3 they're implemented slightly differently. And there is a new component available which adds an additional dimension to define security on the object, Roles. So now instead of selecting individual users or groups of users (defined as an Alias in User Admin), you can select a particular role. And if a user has that role, they are granted that level of access. This can allow for a much more flexible and manageable security model instead of trying to manage with just user and group access as people come and go in the organization. The way that it is enabled is still through configuration entries. First log in as an administrator and go to Administration -> Admin Server. On the Component Manager page, click the 'advanced component manager' link in the description paragraph at the top. In the list of Disabled Components, enable the RoleEntityACL component. Then click the General Configuration link on the left. In the Additional Configuration Variables text area, enter the new configuration values: UseEntitySecurity=true SpecialAuthGroups=<comma separated list of Security Groups to honor ACLs> The SpecialAuthGroups should be a list of Security Groups that honor the ACL fields. If an ACL is applied to a content item with a Security Group outside this list, it will be ignored. Save the settings and restart the instance. Upon restart, three new metadata fields will be created: xClbraUserList, xClbraAliasList, xClbraRoleList. If you are using OracleTextSearch as the search indexer, be sure to run a Fast Rebuild on the collection. On the Check In, Search, and Update pages, values are added by simply typing in the value and getting a type-ahead list of possible values. Select the value, click Add and then set the level of access (Read, Write, Delete, or Admin). If all of the fields are blank, then it simply falls back to just Security Group and Account access. For Users and Groups, these values are automatically picked up from the corresponding database tables. In the case of Roles, this is an explicitly defined list of choices that are made available. These values must match the role that is being defined from WebLogic Server or you LDAP/AD repository. To add these values, go to Administration -> Admin Applets -> Configuration Manager. On the Views tab, edit the values for the ExternalRolesView. By default, 'guest' and 'authenticated' are added. Once added to through the view, they will be available to select from for the Roles Access List. As for how they are stored in the metadata fields, each entry starts with it's identifier: ampersand (&) symbol for users, "at" (@) symbol for groups, and colon (:) for roles. Following that is the entity name. And at the end is the level of access in paranthesis. e.g. (RWDA). And each entry is separated by a comma. So if you were populating values through batch loader or an external source, the values would be defined this way. Detailed information on Access Control Lists can be found in the Oracle Fusion Middleware System Administrator's Guide for Oracle Content Server.

• Delegation of Solaris Zone Administration

  - by darrenm

  In Solaris 11 'Zone Delegation' is a built in feature. The Zones system now uses finegrained RBAC authorisations to allow delegation of management of distinct zones, rather than all zones which is what the 'Zone Management' RBAC profile did in Solaris 10.The data for this can be stored with the Zone or you could also create RBAC profiles (that can even be stored in NIS or LDAP) for granting access to specific lists of Zones to administrators.For example lets say we have zones named zoneA through zoneF and we have three admins alice, bob, carl.  We want to grant a subset of the zone management to each of them.We could do that either by adding the admin resource to the appropriate zones via zonecfg(1M) or we could do something like this with RBAC data directly: First lets look at an example of storing the data with the zone. # zonecfg -z zoneA zonecfg:zoneA> add admin zonecfg:zoneA> set user=alice zonecfg:zoneA> set auths=manage zonecfg:zoneA> end zonecfg:zoneA> commit zonecfg:zoneA> exit Now lets look at the alternate method of storing this directly in the RBAC database, but we will show all our admins and zones for this example: # usermod -P +Zone Management -A +solaris.zone.manage/zoneA alice # usermod -A +solaris.zone.login/zoneB alice # usermod -P +Zone Management-A +solaris.zone.manage/zoneB bob # usermod -A +solaris.zone.manage/zoneC bob # usermod -P +Zone Management-A +solaris.zone.manage/zoneC carl # usermod -A +solaris.zone.manage/zoneD carl # usermod -A +solaris.zone.manage/zoneE carl # usermod -A +solaris.zone.manage/zoneF carl In the above alice can only manage zoneA, bob can manage zoneB and zoneC and carl can manage zoneC through zoneF.  The user alice can also login on the console to zoneB but she can't do the operations that require the solaris.zone.manage authorisation on it.Or if you have a large number of zones and/or admins or you just want to provide a layer of abstraction you can collect the authorisation lists into an RBAC profile and grant that to the admins, for example lets great an RBAC profile for the things that alice and carl can do. # profiles -p 'Zone Group 1' profiles:Zone Group 1> set desc="Zone Group 1" profiles:Zone Group 1> add profile="Zone Management" profiles:Zone Group 1> add auths=solaris.zone.manage/zoneA profiles:Zone Group 1> add auths=solaris.zone.login/zoneB profiles:Zone Group 1> commit profiles:Zone Group 1> exit # profiles -p 'Zone Group 3' profiles:Zone Group 1> set desc="Zone Group 3" profiles:Zone Group 1> add profile="Zone Management" profiles:Zone Group 1> add auths=solaris.zone.manage/zoneD profiles:Zone Group 1> add auths=solaris.zone.manage/zoneE profiles:Zone Group 1> add auths=solaris.zone.manage/zoneF profiles:Zone Group 1> commit profiles:Zone Group 1> exit Now instead of granting carl  and aliace the 'Zone Management' profile and the authorisations directly we can just give them the appropriate profile. # usermod -P +'Zone Group 3' carl # usermod -P +'Zone Group 1' alice If we wanted to store the profile data and the profiles granted to the users in LDAP just add '-S ldap' to the profiles and usermod commands. For a documentation overview see the description of the "admin" resource in zonecfg(1M), profiles(1) and usermod(1M)

• MP3 files cut off in the Ubuntu One Android app

  - by rudefyet

  I noticed today on my phone (Droid X running Android 2.2.1) that when streaming the Ubuntu One app would skip to the next song before the previous one had finished. Looking into it, one of the mp3s downloaded from the server was only 2.5MB instead of 4.2MB as it shows on the server itself via one.ubuntu.com. It's happened with multiple tracks today (I remember it happening once the first time I used the app too but shrugged it off as a glitch). The app itself shows a star on the playlist item indicating the file was downloaded even though it was apparently cut off for some reason, perhaps lack of good cell coverage, or some sort of dropped connection. It seems like the latter may be happening and instead of showing an error or retrying it just stops and shows the download is complete.

• How to export ECC key and Cert from NSS DB and import into JKS keystore and Oracle Wallet

  - by mv

  How to export ECC key and Cert from NSS DB and import into JKS keystore and Oracle Wallet In this blog I will write about how to extract a cert and key from NSS Db and import it to a JKS Keystore and then import that JKS Keystore into Oracle Wallet. 1. Set Java Home I pointed it to JRE 1.6.0_22 $ export JAVA_HOME=/usr/java/jre1.6.0_22/ 2. Create a self signed ECC cert in NSS DB I created NSS DB with self signed ECC certificate. If you already have NSS Db with ECC cert (and key) skip this step. $export NSS_DIR=/export/home/nss/ $$NSS_DIR/certutil -N -d . $$NSS_DIR/certutil -S -x -s "CN=test,C=US" -t "C,C,C" -n ecc-cert -k ec -q nistp192 -d . 3. Export ECC cert and key using pk12util Use NSS tool pk12util to export this cert and key into a p12 file      $$NSS_DIR/pk12util -o ecc-cert.p12 -n ecc-cert -d . -W password 4. Use keytool to create JKS keystore and import this p12 file 4.1 Import p12 file created above into a JKS keystore $JAVA_HOME/bin/keytool -importkeystore -srckeystore ecc-cert.p12 -srcstoretype PKCS12 -deststoretype JKS -destkeystore ecc.jks -srcstorepass password -deststorepass password -srcalias ecc-cert -destalias ecc-cert -srckeypass password -destkeypass password -v But if an error as shown is encountered, keytool error: java.security.UnrecoverableKeyException: Get Key failed: EC KeyFactory not available java.security.UnrecoverableKeyException: Get Key failed: EC KeyFactory not available        at com.sun.net.ssl.internal.pkcs12.PKCS12KeyStore.engineGetKey(Unknown Source)         at java.security.KeyStoreSpi.engineGetEntry(Unknown Source)         at java.security.KeyStore.getEntry(Unknown Source)         at sun.security.tools.KeyTool.recoverEntry(Unknown Source)         at sun.security.tools.KeyTool.doImportKeyStoreSingle(Unknown Source)         at sun.security.tools.KeyTool.doImportKeyStore(Unknown Source)         at sun.security.tools.KeyTool.doCommands(Unknown Source)         at sun.security.tools.KeyTool.run(Unknown Source)         at sun.security.tools.KeyTool.main(Unknown Source) Caused by: java.security.NoSuchAlgorithmException: EC KeyFactory not available         at java.security.KeyFactory.<init>(Unknown Source)         at java.security.KeyFactory.getInstance(Unknown Source)         ... 9 more 4.2 Create a new PKCS11 provider If you didn't get an error as shown above skip this step. Since we already have NSS libraries built with ECC, we can create a new PKCS11 provider Create ${java.home}/jre/lib/security/nss.cfg as follows: name = NSS     nssLibraryDirectory = ${nsslibdir}    nssDbMode = noDb    attributes = compatibility where nsslibdir should contain NSS libs with ECC support. Add the following line to ${java.home}/jre/lib/security/java.security :      security.provider.9=sun.security.pkcs11.SunPKCS11 ${java.home}/lib/security/nss.cfg Note that those who are using Oracle iPlanet Web Server or Oracle Traffic Director, NSS libs built with ECC are in <ws_install_dir>/lib or <otd_install_dir>/lib. 4.3. Now keytool should work Now you can try the same keytool command and see that it succeeds : $JAVA_HOME/bin/keytool -importkeystore -srckeystore ecc-cert.p12 -srcstoretype PKCS12 -deststoretype JKS -destkeystore ecc.jks -srcstorepass password -deststorepass password -srcalias ecc-cert -destalias ecc-cert -srckeypass password -destkeypass password -v [Storing ecc.jks] 5. Convert JKS keystore into an Oracle Wallet You can export this cert and key from JKS keystore and import it into an Oracle Wallet if you need using orapki tool as shown below. Make sure that orapki you use supports ECC. Also for ECC you MUST use "-jsafe" option. $ orapki wallet create -pwd password  -wallet .  -jsafe $ orapki wallet jks_to_pkcs12 -wallet . -pwd password -keystore ecc.jks -jkspwd password -jsafe AS $orapki wallet display -wallet . -pwd welcome1  -jsafeOracle PKI Tool : Version 11.1.2.0.0Copyright (c) 2004, 2012, Oracle and/or its affiliates.

• Squid + Dans Guardian (simple configuration)

  - by The Digital Ninja

  I just built a new proxy server and compiled the latest versions of squid and dansguardian. We use basic authentication to select what users are allowed outside of our network. It seems squid is working just fine and accepts my username and password and lets me out. But if i connect to dans guardian, it prompts for username and password and then displays a message saying my username is not allowed to access the internet. Its pulling my username for the error message so i know it knows who i am. The part i get confused on is i thought that part was handled all by squid, and squid is working flawlessly. Can someone please double check my config files and tell me if i'm missing something or there is some new option i must set to get this to work. dansguardian.conf # Web Access Denied Reporting (does not affect logging) # # -1 = log, but do not block - Stealth mode # 0 = just say 'Access Denied' # 1 = report why but not what denied phrase # 2 = report fully # 3 = use HTML template file (accessdeniedaddress ignored) - recommended # reportinglevel = 3 # Language dir where languages are stored for internationalisation. # The HTML template within this dir is only used when reportinglevel # is set to 3.

• How to automatically mount hibernated NTFS to read-only?

  - by Piotr

  Is there any way to set up Ubuntu this way: If I can't mount the filesystem in rw mode, then mount it in ro mode in the same directory. In result I should not come across the notification that the system can't mount the filesystem (Skip or manual fix notification). SO when I start the system I should have my ntfs partitions mounted either in rw or ro mode depends if the windows is hibernated. fstab entry: #/dev/sda7 UUID=D0B43178B43161E0 /media/Dane ntfs defaults,errors=remount-ro 0 1 "mount -a" result: The disk contains an unclean file system (0, 0). Metadata kept in Windows cache, refused to mount. Failed to mount '/dev/sda7': Operation not permitted The NTFS partition is in an unsafe state. Please resume and shutdown Windows fully (no hibernation or fast restarting), or mount the volume read-only with the 'ro' mount option. I have ubuntu 13.10 and win8. I use uefi secure boot.

• Confused about ASP.NET Ajax, jQuery and JavaScript

  - by Mr.Y

  Yesterday, I read couple of chapters on ASP.NET Ajax and jQuery from my ASP.NET 4 book and I found those frameworks pretty interesting and decide to learn more about them. Today, I borrowed some books from library on Ajax and JavaScript. It seems ASP.NET Ajax is different from Ajax and jQuery seems like the "new" JavaScript. Does it mean that I can skip JavaScript and learn jQuery directly? On the other hand, the non-ASP.NET Ajax book I borrowed seems to apply to the client side web programming only and looks quite different from what I learned from ASP.NET Ajax. If I'm an ASP.NET developer, I guess I should stick with ASP.NET Ajax instead of client side Ajax right? What about PHP? Is there a "PHP Ajax" similar to ASP.NET Ajax? It's not that I'm lazy to learn other tools, but I just want to focus on the right ones.

• Streaming desktop with avconv - severe sound issues

  - by Tommy Brunn

  I'm trying to do some live streaming in Ubuntu 12.10, but I'm having some problems with audio. More specifically, the quality is complete garbage and it's at least 10 seconds out of sync with the video. I'm using an excellent guide found here to set up my loopback devices so that I can combine the desktop audio with the microphone input. It seems to work, as I'm able to stream both audio and video to Twitch.tv. But, as I said, the audio quality is terrible. The microphone audio is very, very low, but if I increase it, I get a horrible garbled sound that is absolutely unbearable. Nothing like that is present during VoIP calls or when recording sound alone with the sound recorder, so it's not an issue with the microphone itself. The entire audio stream is also delayed about 10-15 seconds compared to the video stream. I put together an imgur album of my settings. Here is some example output from when I'm streaming: avconv version 0.8.4-6:0.8.4-0ubuntu0.12.10.1, Copyright (c) 2000-2012 the Libav developers built on Nov 6 2012 16:51:11 with gcc 4.7.2 [x11grab @ 0x162fd80] device: :0.0+570,262 -> display: :0.0 x: 570 y: 262 width: 1280 height: 720 [x11grab @ 0x162fd80] shared memory extension found [x11grab @ 0x162fd80] Estimating duration from bitrate, this may be inaccurate Input #0, x11grab, from ':0.0+570,262': Duration: N/A, start: 1353181686.735113, bitrate: 884736 kb/s Stream #0.0: Video: rawvideo, bgra, 1280x720, 884736 kb/s, 30 tbr, 1000k tbn, 30 tbc [alsa @ 0x163fce0] capture with some ALSA plugins, especially dsnoop, may hang.

Any ideas on how I can resolve this? The video delay is perfectly acceptable, so I wouldn't think that it's a network issue that's causing the delay in the audio. Any help would be appreciated.
