  • CCNet TFS Migration - Dealing with left over folders

    - by Michael Stephenson
    Im currently in the process of migrating our many BizTalk projects from MKS source control to TFS.  While we will be using TFS for work item tracking and source control etc we will be continuing to use Cruise Control for continuous integration although im updating this to CCNet 1.5 at the same time. Ill post a few things as much as a reminder to myself about some of the problems we come across. Problem After the first build of our code the next time a build is triggered an error is encountered by the TFS source control block refreshing the source code. System.IO.IOException: The directory is not empty.    at System.IO.Directory.DeleteHelper(String fullPath, String userPath, Boolean recursive)    at System.IO.Directory.Delete(String fullPath, String userPath, Boolean recursive)    at ThoughtWorks.CruiseControl.Core.Sourcecontrol.Vsts.deleteDirectory(String path)    at ThoughtWorks.CruiseControl.Core.Sourcecontrol.Vsts.GetSource(IIntegrationResult result)    at ThoughtWorks.CruiseControl.Core.IntegrationRunner.Build(IIntegrationResult result)    at ThoughtWorks.CruiseControl.Core.IntegrationRunner.Integrate(IntegrationRequest request) System.IO.IOException: The directory is not empty. at System.IO.Directory.DeleteHelper(String fullPath, String userPath, Boolean recursive) at System.IO.Directory.Delete(String fullPath, String userPath, Boolean recursive) at ThoughtWorks.CruiseControl.Core.Sourcecontrol.Vsts.deleteDirectory(String path) at ThoughtWorks.CruiseControl.Core.Sourcecontrol.Vsts.GetSource(IIntegrationResult result) at ThoughtWorks.CruiseControl.Core.IntegrationRunner.Build(IIntegrationResult result) at ThoughtWorks.CruiseControl.Core.IntegrationRunner.Integrate(IntegrationRequest request) Project: Bupa.BPI.Documents Date of build: 2011-01-28 14:54:21 Running time: 00:00:05 Integration Request: Build (ForceBuild) triggered from VMOPBZDEV11 Solution The problem seems to be with a folder called TestLocations which is created by the build process and used along with the file adapter as a way to get messages into BizTalk.  For some reason the source control block when it does a full refresh of the code does not get rid of this folder and then complains thats a problem and fails the build. Interestingly there are other folders created by the build which are deleted fine.  My assumption is that this if something to do with the file adapter polling the directory.  However note that we have not had this problem with other source control blocks in the past. To workaround this I have added a prebuild task to the ccnet.config file to delete this folder before the source control block is executed.  See below for example < prebuild> exec>executable>cmd.exe</executable>buildArgs>/c "if exist "C:\<MyCode>\TestLocations" rd /s /q "C:\<MyCode>\TestLocations""</buildArgs>exec> prebuild> < < < </ </

  • Cannot install any Feature/Role on Windows Server 2008 R2 Standard

    - by Parsa
    I was trying to install Exchange 2010 prerequisites, when I encountered some error. All look like the same. Like this one: Error: Installation of [Windows Process Activation Service] Configuration APIs failed. the server needs to be restarted to undo the changes. My server is running Windows Server 2008 R2 Standard Edition. UPDATE: I tried installing the prerequisites one by one using PowerShell. Now I have errors on RPC over Http proxy: Installation of [Web Server (IIS)] Tracing Failed, Attempt to install tracing failed with error code 0x80070643. Fatal error during installation. Searching about the error code doesn't tell me much more than something went wrong when trying to update windows. Installing Http Tracing alone also doesn't make any difference.

  • SQL SERVER – ASYNC_IO_COMPLETION – Wait Type – Day 11 of 28

    - by pinaldave
    For any good system three things are vital: CPU, Memory and IO (disk). Among these three, IO is the most crucial factor of SQL Server. Looking at real-world cases, I do not see IT people upgrading CPU and Memory frequently. However, the disk is often upgraded for either improving the space, speed or throughput. Today we will look at another IO-related wait type. From Book On-Line: Occurs when a task is waiting for I/Os to finish. ASYNC_IO_COMPLETION Explanation: Any tasks are waiting for I/O to finish. If by any means your application that’s connected to SQL Server is processing the data very slowly, this type of wait can occur. Several long-running database operations like BACKUP, CREATE DATABASE, ALTER DATABASE or other operations can also create this wait type. Reducing ASYNC_IO_COMPLETION wait: When it is an issue related to IO, one should check for the following things associated to IO subsystem: Look at the programming and see if there is any application code which processes the data slowly (like inefficient loop, etc.). Note that it should be re-written to avoid this  wait type. Proper placing of the files is very important. We should check the file system for proper placement of the files – LDF and MDF on separate drive, TempDB on another separate drive, hot spot tables on separate filegroup (and on separate disk), etc. Check the File Statistics and see if there is a higher IO Read and IO Write Stall SQL SERVER – Get File Statistics Using fn_virtualfilestats. Check event log and error log for any errors or warnings related to IO. If you are using SAN (Storage Area Network), check the throughput of the SAN system as well as configuration of the HBA Queue Depth. In one of my recent projects, the SAN was performing really badly and so the SAN administrator did not accept it. After some investigations, he agreed to change the HBA Queue Depth on the development setup (test environment). As soon as we changed the HBA Queue Depth to quite a higher value, there was a sudden big improvement in the performance. It is very likely to happen that there are no proper indexes on the system and yet there are lots of table scans and heap scans. Creating proper index can reduce the IO bandwidth considerably. If SQL Server can use appropriate cover index instead of clustered index, it can effectively reduce lots of CPU, Memory and IO (considering cover index has lesser columns than cluster table and all other; it depends upon the situation). You can refer to the following two articles I wrote that talk about how to optimize indexes: Create Missing Indexes Drop Unused Indexes Checking Memory Related Perfmon Counters SQLServer: Memory Manager\Memory Grants Pending (Consistent higher value than 0-2) SQLServer: Memory Manager\Memory Grants Outstanding (Consistent higher value, Benchmark) SQLServer: Buffer Manager\Buffer Hit Cache Ratio (Higher is better, greater than 90% for usually smooth running system) SQLServer: Buffer Manager\Page Life Expectancy (Consistent lower value than 300 seconds) Memory: Available Mbytes (Information only) Memory: Page Faults/sec (Benchmark only) Memory: Pages/sec (Benchmark only) Checking Disk Related Perfmon Counters Average Disk sec/Read (Consistent higher value than 4-8 millisecond is not good) Average Disk sec/Write (Consistent higher value than 4-8 millisecond is not good) Average Disk Read/Write Queue Length (Consistent higher value than benchmark is not good) Read all the post in the Wait Types and Queue series. Note: The information presented here is from my experience and there is no way that I claim it to be accurate. I suggest reading Book OnLine for further clarification. All the discussions of Wait Stats in this blog are generic and vary from system to system. It is recommended that you test this on a development server before implementing it to a production server.

  • Virtualization in Solaris 11 Express

    - by lynn.rohrer(at)oracle.com
    In Oracle Solaris 10 we introduced Oracle Solaris Containers -- lightweight virtual application environments that allow you to consolidate your Oracle Solaris applications onto a single Oracle Solaris server and make the most of your system resources.The majority of our customers are now using Oracle Solaris Containers on their enterprise systems for applications ranging from web servers to Oracle Database installations. We can also make these Containers highly available with Oracle Solaris Cluster, the industry's first virtualization-aware enterprise cluster product. Using Oracle Solaris Cluster you can failover applications in a Container to another Container on a single system or across systems for additional availability.We've added significant features in Oracle Solaris 11 Express to improve and extend the Oracle Solaris Zone model:Integration of Zones with our new Solaris 11 packaging system (aka Image Packaging System) to provide easy software updates within a zoneSupport for Oracle Solaris 10 Zones to run your Solaris 10 applications unaltered on an Oracle Solaris 11 Express systemIntegration with the new Oracle Solaris 11 network stack architecture (more on this in a future blog post)Improved observability with the zonestat management interface and commandsDelegated administration rights for owners of individual non-global zonesTight integration with Oracle Solaris ZFS to allow dedicated datasets per zoneWith ZFS as the default file system we can now provide easy to manage Boot Environments for zonesThis quick summary is just to whet your appetite to learn more about Oracle Solaris 11 Express Zones enhancements. Fortunately we can serve a full meal at the Oracle Solaris 11 Express Technology Spotlight on Virtualization page on the Oracle Technical Network.

  • Securing ASP.Net Pages - Forms Authentication - C# and .Net 4

    - by SAMIR BHOGAYTA
    ASP.Net has a built-in feature named Forms Authentication that allows a developer to easily secure certain areas of a web site. In this post I'm going to build a simple authentication sample using C# and ASP.Net 4.0 (still in beta as of the posting date). Security settings with ASP.Net is configured from within the web.config file. This is a standard ASCII file, with an XML format, that is located in the root of your web application. Here is a sample web.config file: configuration system.web authenticationmode="Forms" formsname="TestAuthCookie"loginUrl="login.aspx"timeout="30" credentialspasswordFormat="Clear" username="user1"password="pass1"/ username="user2"password="pass2"/ authorization denyusers="?"/ compilationtargetFramework="4.0"/ pagescontrolRenderingCompatibilityVersion="3.5"clientIDMode="AutoID"/ Here is the complete source of the sample login.aspx page: div Username: asp:TextBox ID="txtUsername" runat="server":TextBox Password: asp:TextBox ID="txtPassword" runat="server":TextBox asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Login" / asp:Label ID="lblStatus" runat="server" Text="Please login":Label /div And here is the complete source of the login.aspx.cs file: using System; using System.Web.UI.WebControls; using System.Web.Security; public partial class Default3 : System.Web.UI.Page { protected void Button1_Click(object sender, EventArgs e) { if (FormsAuthentication.Authenticate(txtUsername.Text, txtPassword.Text)) { lblStatus.Text = ("Welcome " + txtUsername.Text); FormsAuthentication.RedirectFromLoginPage(txtUsername.Text, true); } else { lblStatus.Text = "Invalid login!"; } } }

  • Auto DOP and Concurrency

    - by jean-pierre.dijcks
    After spending some time in the cloud, I figured it is time to come down to earth and start discussing some of the new Auto DOP features some more. As Database Machines (the v2 machine runs Oracle Database 11.2) are effectively selling like hotcakes, it makes some sense to talk about the new parallel features in more detail. For basic understanding make sure you have read the initial post. The focus there is on Auto DOP and queuing, which is to some extend the focus here. But now I want to discuss the concurrency a little and explain some of the relevant parameters and their impact, specifically in a situation with concurrency on the system. The goal of Auto DOP The idea behind calculating the Automatic Degree of Parallelism is to find the highest possible DOP (ideal DOP) that still scales. In other words, if we were to increase the DOP even more  above a certain DOP we would see a tailing off of the performance curve and the resource cost / performance would become less optimal. Therefore the ideal DOP is the best resource/performance point for that statement. The goal of Queuing On a normal production system we should see statements running concurrently. On a Database Machine we typically see high concurrency rates, so we need to find a way to deal with both high DOP’s and high concurrency. Queuing is intended to make sure we Don’t throttle down a DOP because other statements are running on the system Stay within the physical limits of a system’s processing power Instead of making statements go at a lower DOP we queue them to make sure they will get all the resources they want to run efficiently without trashing the system. The theory – and hopefully – practice is that by giving a statement the optimal DOP the sum of all statements runs faster with queuing than without queuing. Increasing the Number of Potential Parallel Statements To determine how many statements we will consider running in parallel a single parameter should be looked at. That parameter is called PARALLEL_MIN_TIME_THRESHOLD. The default value is set to 10 seconds. So far there is nothing new here…, but do realize that anything serial (e.g. that stays under the threshold) goes straight into processing as is not considered in the rest of this post. Now, if you have a system where you have two groups of queries, serial short running and potentially parallel long running ones, you may want to worry only about the long running ones with this parallel statement threshold. As an example, lets assume the short running stuff runs on average between 1 and 15 seconds in serial (and the business is quite happy with that). The long running stuff is in the realm of 1 – 5 minutes. It might be a good choice to set the threshold to somewhere north of 30 seconds. That way the short running queries all run serial as they do today (if it ain’t broken, don’t fix it) and allows the long running ones to be evaluated for (higher degrees of) parallelism. This makes sense because the longer running ones are (at least in theory) more interesting to unleash a parallel processing model on and the benefits of running these in parallel are much more significant (again, that is mostly the case). Setting a Maximum DOP for a Statement Now that you know how to control how many of your statements are considered to run in parallel, lets talk about the specific degree of any given statement that will be evaluated. As the initial post describes this is controlled by PARALLEL_DEGREE_LIMIT. This parameter controls the degree on the entire cluster and by default it is CPU (meaning it equals Default DOP). For the sake of an example, let’s say our Default DOP is 32. Looking at our 5 minute queries from the previous paragraph, the limit to 32 means that none of the statements that are evaluated for Auto DOP ever runs at more than DOP of 32. Concurrently Running a High DOP A basic assumption about running high DOP statements at high concurrency is that you at some point in time (and this is true on any parallel processing platform!) will run into a resource limitation. And yes, you can then buy more hardware (e.g. expand the Database Machine in Oracle’s case), but that is not the point of this post… The goal is to find a balance between the highest possible DOP for each statement and the number of statements running concurrently, but with an emphasis on running each statement at that highest efficiency DOP. The PARALLEL_SERVER_TARGET parameter is the all important concurrency slider here. Setting this parameter to a higher number means more statements get to run at their maximum parallel degree before queuing kicks in.  PARALLEL_SERVER_TARGET is set per instance (so needs to be set to the same value on all 8 nodes in a full rack Database Machine). Just as a side note, this parameter is set in processes, not in DOP, which equates to 4* Default DOP (2 processes for a DOP, default value is 2 * Default DOP, hence a default of 4 * Default DOP). Let’s say we have PARALLEL_SERVER_TARGET set to 128. With our limit set to 32 (the default) we are able to run 4 statements concurrently at the highest DOP possible on this system before we start queuing. If these 4 statements are running, any next statement will be queued. To run a system at high concurrency the PARALLEL_SERVER_TARGET should be raised from its default to be much closer (start with 60% or so) to PARALLEL_MAX_SERVERS. By using both PARALLEL_SERVER_TARGET and PARALLEL_DEGREE_LIMIT you can control easily how many statements run concurrently at good DOPs without excessive queuing. Because each workload is a little different, it makes sense to plan ahead and look at these parameters and set these based on your requirements.

  • What steps can you take to ensure sane build environments when compiling software?

    - by Chris Adams
    Hi guys, I've been stuck with a compilation problem when building a standardised virtual machine on CentOS 5.4, and I'm in the dark here as to a) why this error is occurring, and b) how to fix it, and in the hope that someone else stumbles across this problem too, I'm hoping someone can help me find the solution here. I'm getting a configure: error: newly created file is older than distributed files! error when trying to compile Ruby Enterprise like below when I try to run the installer, and the solutions offered to on the forums (of checking the tine, and touching the files to update the time associated with them) don't seem to be helping here. What steps can I take to work out what the cause of this problem? [vagrant@vagrant-centos-5 ruby-enterprise-1.8.7-2009.10]$ sudo ./installer Welcome to the Ruby Enterprise Edition installer This installer will help you install Ruby Enterprise Edition 1.8.7-2009.10. Don't worry, none of your system files will be touched if you don't want them to, so there is no risk that things will screw up. You can expect this from the installation process: 1. Ruby Enterprise Edition will be compiled and optimized for speed for this system. 2. Ruby on Rails will be installed for Ruby Enterprise Edition. 3. You will learn how to tell Phusion Passenger to use Ruby Enterprise Edition instead of regular Ruby. Press Enter to continue, or Ctrl-C to abort.

I tried this after reading this post here of someone having a similar problem [vagrant@vagrant-centos-5 ruby-enterprise-1.8.7-2009.10]$ date Tue Apr 27 08:09:05 BST 2010 The other approach I've tried is to touch the top level the files in the build folder like suggested here, but this hasn't worked either (an to be honest, I'm not sure why it would have worked either) [vagrant@vagrant-centos-5 ruby-enterprise-1.8.7-2009.10]$ sudo touch ruby-enterprise-1.8.7-2009.10/* I'm not sure what I can do next here - the problem seems to be the bash configure script that returns this error error: newly created file is older than distributed files!, at line :2214 { echo "$as_me:$LINENO: checking whether build environment is sane" >&5 echo $ECHO_N "checking whether build environment is sane... $ECHO_C" >&6; } # Just in case sleep 1 echo timestamp > conftest.file # Do `set' in a subshell so we don't clobber the current shell's # arguments.

There's nothing I see in the crontab that suggests any hourly tasks are run that might change the state of the system enough make a difference to this script working. I'm totally at a loss when it comes to debugging beyond here. What's the best approach to take here? Thanks

  • XNA 2D Collision with specific tiles

    - by zenzero
    I am new to game programming and to these sites for help. I am making a 2D game but I can't seem to get the collision between my character and certain tiles. I have a map filled with grass tiles and water tiles and I want to keep my character from walking on the water tiles. I have a Tiles class that I use so that the tiles are objects and also has the collision method in it, a TileEngine class used create the map and it also holds a list of Tiles, and the class James which is for my character. I also have a Camera class that centers the camera on my character if that has anything to do with the problem. The character's movement is intended to be restricted to 4 directions(up, down, left, right). As an extra note, the bottom right water tile does have collision, but the collision does not occur for any of the other water tiles.

    I am using http://pam-face-authentication.org/ to log into my system using face detection and it is working just great except for one thing,The authentication runs out of the box, but it doesn't unlock my keyring. So after loging into my system, I see my desktop and everything normally but then a password prompt pops-up asking for Gnome-keyring, I think if it can log me into the system just fine then it should also be able to unlock the gnome-kerying.

  • Announcing Unbreakable Enterprise Kernel Release 3 for Oracle Linux

    - by Lenz Grimmer
    We are excited to announce the general availability of the Unbreakable Enterprise Kernel Release 3 for Oracle Linux 6. The Unbreakable Enterprise Kernel Release 3 (UEK R3) is Oracle's third major supported release of its heavily tested and optimized Linux kernel for Oracle Linux 6 on the x86_64 architecture. UEK R3 is based on mainline Linux version 3.8.13. Some notable highlights of this release include: Inclusion of DTrace for Linux into the kernel (no longer a separate kernel image). DTrace for Linux now supports probes for user-space statically defined tracing (USDT) in programs that have been modified to include embedded static probe points Production support for Linux containers (LXC) which were previously released as a technology preview Btrfs file system improvements (subvolume-aware quota groups, cross-subvolume reflinks, btrfs send/receive to transfer file system snapshots or incremental differences, file hole punching, hot-replacing of failed disk devices, device statistics) Improved support for Control Groups (cgroups)  The ext4 file system can now store the content of a small file inside the inode (inline_data) TCP fast open (TFO) can speed up the opening of successive TCP connections between two endpoints FUSE file system performance improvements on NUMA systems Support for the Intel Ivy Bridge (IVB) processor family Integration of the OpenFabrics Enterprise Distribution (OFED) 2.0 stack, supporting a wide range of Infinband protocols including updates to Oracle's Reliable Datagram Sockets (RDS) Numerous driver updates in close coordination with our hardware partners UEK R3 uses the same versioning model as the mainline Linux kernel version. Unlike in UEK R2 (which identifies itself as version "2.6.39", even though it is based on mainline Linux 3.0.x), "uname" returns the actual version number (3.8.13). For further details on the new features, changes and any known issues, please consult the Release Notes. The Unbreakable Enterprise Kernel Release 3 and related packages can be installed using the yum package management tool on Oracle Linux 6 Update 4 or newer, both from the Unbreakable Linux Network (ULN) and our public yum server. Please follow the installation instructions in the Release Notes for a detailed description of the steps involved. The kernel source tree will also available via the git source code revision control system from https://oss.oracle.com/git/?p=linux-uek3-3.8.git If you would like to discuss your experiences with Oracle Linux and UEK R3, we look forward to your feedback on our public Oracle Linux Forum.

  • SQL SERVER – IO_COMPLETION – Wait Type – Day 10 of 28

    - by pinaldave
    For any good system three things are vital: CPU, Memory and IO (disk). Among these three, IO is the most crucial factor of SQL Server. Looking at real-world cases, I do not see IT people upgrading CPU and Memory frequently. However, the disk is often upgraded for either improving the space, speed or throughput. Today we will look at an IO-related wait types. From Book On-Line: Occurs while waiting for I/O operations to complete. This wait type generally represents non-data page I/Os. Data page I/O completion waits appear as PAGEIOLATCH_* waits. IO_COMPLETION Explanation: Any tasks are waiting for I/O to finish. This is a good indication that IO needs to be looked over here. Reducing IO_COMPLETION wait: When it is an issue concerning the IO, one should look at the following things related to IO subsystem: Proper placing of the files is very important. We should check the file system for proper placement of files – LDF and MDF on a separate drive, TempDB on another separate drive, hot spot tables on separate filegroup (and on separate disk),etc. Check the File Statistics and see if there is higher IO Read and IO Write Stall SQL SERVER – Get File Statistics Using fn_virtualfilestats. Check event log and error log for any errors or warnings related to IO. If you are using SAN (Storage Area Network), check the throughput of the SAN system as well as the configuration of the HBA Queue Depth. In one of my recent projects, the SAN was performing really badly so the SAN administrator did not accept it. After some investigations, he agreed to change the HBA Queue Depth on development (test environment) set up and as soon as we changed the HBA Queue Depth to quite a higher value, there was a sudden big improvement in the performance. It is very possible that there are no proper indexes in the system and there are lots of table scans and heap scans. Creating proper index can reduce the IO bandwidth considerably. If SQL Server can use appropriate cover index instead of clustered index, it can effectively reduce lots of CPU, Memory and IO (considering cover index has lesser columns than cluster table and all other; it depends upon the situation). You can refer to the two articles that I wrote; they are about how to optimize indexes: Create Missing Indexes Drop Unused Indexes Checking Memory Related Perfmon Counters SQLServer: Memory Manager\Memory Grants Pending (Consistent higher value than 0-2) SQLServer: Memory Manager\Memory Grants Outstanding (Consistent higher value, Benchmark) SQLServer: Buffer Manager\Buffer Hit Cache Ratio (Higher is better, greater than 90% for usually smooth running system) SQLServer: Buffer Manager\Page Life Expectancy (Consistent lower value than 300 seconds) Memory: Available Mbytes (Information only) Memory: Page Faults/sec (Benchmark only) Memory: Pages/sec (Benchmark only) Checking Disk Related Perfmon Counters Average Disk sec/Read (Consistent higher value than 4-8 millisecond is not good) Average Disk sec/Write (Consistent higher value than 4-8 millisecond is not good) Average Disk Read/Write Queue Length (Consistent higher value than benchmark is not good) Note: The information presented here is from my experience and there is no way that I claim it to be accurate. I suggest reading Book OnLine for further clarification. All the discussions of Wait Stats in this blog are generic and vary from system to system. It is recommended that you test this on a development server before implementing it to a production server.

    I am extremely new to Ubuntu and need to work on EdX platform. I need to install the NFS Client on Ubuntu 12.04 for the same.

I am clueless as to where can I find this missing file as stated in the output. I tried to google about this problem but none of the solutions I came across have helped or I have not been able to understand some of them. Any help would really be appreciated. Thanks in advance for your time and attention.

  • Windows 7 - Ubuntu 10.10 Dual Boot Partitioning Recommendation for HP Laptop OEM

    - by Denja
    Hi Linux Community, After been temporary impressed with the newb Windows 7 and after intensly using it I find my self struggling with the ever slow and buggy windows OS once again. It's Time to go with the Ubuntu/Linux way for a better and faster tomorrow. Unfortunately in my country most Users/Business use Windows based Systems. As a Computer technician i want to learn and use both Systems and possibly introduce New users to more affordable Linux Based Systems. For now I want to create dual-boot or even triple boot layouts on my laptop machine Here's the layout in use now: * (C:) Windows 7 system partition NTFS - 284,89GB (Primary,Boot,Pagefile,Dump) * HP_TOOLS system partition FAT32 - 99MB (Primary) * (D:) RECOVERY partition NTFS - 12,90GB (Primary) * SYSTEM partition NTFS 199MB (Primary) Here's the layout I want to make. * (C:) Windows 7 system partition NTFS - 60GB (Primary) (sda1) * (D:) Windows data partition (user files) NTFS - 60GB(Extended or Primary)(sda2);wanna share with Linux * Linux root Ext4 - 10GB (Primary)(sda3) * Linux swap swap- RAM size, 3GB (sda4) * Linux home Ext4- 164,9GB (Extended)(sda5) Question 1: Is the layout that i want to make correct as the Primary and Extended Partition concerns ? Question 2: Can I definitely get rid of SYSTEM Boot loader of windows? Question 3: If I get rid of HP_TOOLS and RECOVERY partition will it be a problem? Question 4: Based on my layout what is your suggestion for a Triple Boot layout for OSX or Puppy Linux? Thank you in advance for your advises and suggestions.

  • Should classes from the same namespace be kept in the same assembly?

    - by Dan Rasmussen
    For example, ISerializable and the Serializable Attribute are both in the System.Runtime.Serialization namespace, but not the assembly of the same name. On the other hand, DataContract attributes are in the namespace/assembly System.Runtime.Serialization. This causes confusion when a class can have using System.Runtime.Serialization but still not have reference to the System.Runtime.Serialization assembly, meaning DataContract cannot be found. Should this be avoided in practice, or is it common for namespaces to be split over multiple assemblies? What other issues should one be careful of when doing this?

    - by Optimus Prime
    I'm getting "Failed to get i915 symbols, graphics turbo disabled" error message after installing following softwares and few updates from Ubuntu. Django, Mysql server 5.5 Mysql benchmark And i have installed few updates for ubuntu. It was showing as Security Updates for Ubuntu. After installing Updates the update manager showed that i should restart the system. On restart i got following error message. " failed to get i915 symbols, graphics turbo disabled". So i tried the work around mentioned here (using the Live CD) ie add intel_ips to the blacklist echo "blacklist intel_ips" /etc/modprobe.d/blacklist.conf add i915 and intel_ips to /etc/modules echo -e "i915/nintel_ips" /etc/modules Now when start the system it freezes at Ubuntu splash screen. I'm using Ubuntu 12.04 LTS, on Dell inspiron N1040. I need to boot the system as i have spend lot of days configuring. Python and Django. Please help EDIT : OK when i restarted the system yesterday it magically turned on. Now i can view my desktop. But one problem, i can't mount any of the drives. It says failed to mount Drive.
