  • Disaster Recovery Standby Server

    - by user64300
    Hi, I work for a small business with 25 users and 2 servers. 1 server is the DC running Windows Server 2003/Exchange 2003. We want a reliable disaster recovery strategy for this server without having to spend a lot of money. We take regular backups but I have been advised that only an identical server will allow them to be restored easily. I'm trying to come up with a solution that means we don't have to buy two servers at twice the cost everytime we upgrade. I'm toying with the idea of upgrading our DC more frequently (say every 3 years) and then using the old server as the recovery server (temporarily - until we can source a replacement server). However, I won't know whether the backups will restore on the old server until I try it! We're planning to upgrade to Server 2008R2 in the near future so I'm hoping the backup tools will give me some success in restoring to different hardware (or perhaps I can use hyper-v if not). So what I am wondering is whether it is a idea to use old hardware as a disaster recovery strategy (providing we regular test it obviously!).

  • TFS Check in rules

    - by NPehrsson
    Hi I'm out of setting up an TFS server and I want to set some check-in rules. I for example want to be able to set rules about method lenght, complexity and so on, I found NDepend very convenient can I somehow use NDepend to run some rules on the files trying to check in. I also want to be able to bypass the rules sometimes. Are there any blogs or discussions around this, if it wont work with NDepend are there any other tools or ways I can use?

  • What are MVP and MVC and what is the difference?

    - by Wolfbyte
    When looking beyond the RAD (drag-drop and configure) way of building User Interfaces that many tools encourage you are likely to come across 2 design patterns called Model-View-Controller and Model-View-Presenter. My question has two parts to it: What issues do these patterns address? How are they similar? How are they different?

  • Windows 2008 R2 DNS cant resolve own SOA

    - by user46742
    We have two Domain Controllers for our network. They both run DHCP, DNS, and ADS. They are both VM's sitting on MS Hyper V Server 2008 on separate physical hosts. We had our primary DC go down a week ago. I upgraded an already existing VM to Primary DC and built a new VM for the secondary. Both DNS servers are running and the SOA is configured correctly for Primary DC 1. However when I run the best practice analyzer it states the server cannot resolve it's own SOA. Check the configuration in the adapter. I checked and they are configured properly. I also went through the DNS entries thoroughly and made sure there was no records of the previous DC that went down. NSLOOKUP resolves the domain and primary dc fine. I also checked the firewalls on the machines and our physical firewall for any deny packets. Any suggestions? I appreciate any help!

  • how to deal with political differences that lead to dysfunctional development environment

    - by Pierreten
    We have a few liberal programmers on our team who don't use source control, don't manage time effectively and always want to use our budget on useless tools/components that are expensive and things we can build ourselves. They are also loud and disrespectful. Our group of conservatives always have to clean up after them and show them the correct way of doing things. How do we address this discrepancy? Please advise.

  • Implementing C# for the JVM

    - by Rob
    Is anyone attempting to implement C# for the JVM? As a Java developer, I've been eyeing C# with envy, but am unwilling to give up the portability and maturity of the JVM, not to mention the diverse range of tools for it. I know there are some important differences between the JVM and CLR but is there anything that is a showstopper?

  • How to test a site rigorously?

    - by Sarfraz
    Hello, I recently created a big portal site. It's time for putting it to test. How do you guys test a site rigorously? What are the ways and tools for that? Can we sort of mimic hundreds of virtual users visiting the site to see its load handling? The test should be for both security and speed Thanks in advance.

  • Problems Installing Eclipse and Ruby Plugin

    - by Jesse J
    I installed Eclipse on my Ubuntu machine and then the Ruby Development Tools (RDT), but it would crash when I try to alter certain features, like having line numbers, how far back to have history, and the code coloring scheme didn't work fully. I decided to try to uninstall Eclipse by doing sudo aptitude remove Eclipse and then sudo aptitude install eclipse but instead it installed it back with the broken Ruby plugin. I also tried aptitude purge but that didn't help either. How can I freshly reinstall Eclipse and get a properly working Ruby plugin?

  • Oracle: Is there a way to get the column data types for a view?

    - by rally25rs
    For a table in oracle, I can query "all_tab_columns" and get table column information, like the data type, precision, whether or not the column is nullable. In SQL Developer or TOAD, you can click on a view in the GUI and it will spit out a list of the columns that the view returns and the same set of data (data type, precision, nullable, etc). So my question is, is there a way to query this column definition for a view, the way you can for a table? How do the GUI tools do it?

  • erratic response times with Apache 2.0.52 on redhat 4.

    - by Kevin
    Under load, we've noticed response times from Apache vary greatly for the same 7k image. It can range anywhere from .01 seconds to 25 seconds or greater. Unfortunately, due to corporate policy constraints we are pretty much stuck on Apache 2.0.52. I'm at best an Apache novice so I'm in over my head with this problem. My focus recently has turned to our choice of MPM modules. We use the worker model on a dual core hyper threaded blade. It doesn't appear that swapping is an issue, and I don't see any signs of a hardware problem. I've read that worker is optimal on hardware with many CPU's where prefork it more suitable for our specific hardware profile. I can see conceptually how choosing the wrong MPM could result in this erratic behavior, but I'm not confident that it's the root cause here. Has anyone else seen this type of range in your response times for simple static content? What else should I be looking into here?

  • How do you unit test your T-SQL

    - by AlexKuznetsov
    How do you unit test your T-SQL? Which libraries/tools do you use? What percentage of your code is covered by unit tests and how do you measure it? Do you think the time and effort which you invested in your unit testing harness has paid off or not? If you do not use unit testing, can you explain why not?

  • HTML5 applicationCache in local development

    - by jesper
    I'm experimenting with application cache based on this example: http://html5demos.com/html5demo.manifest This example works fine in ff, but when I create analogous site (almost identical) I get only status "UNCACHED (numeric value 0) -- The ApplicationCache object's cache host is not associated with an application cache at this time." I work on xampp and I've set correct mime-type. When the page is loading ff "is asking to store data on your computer for offline use" and when I show Tools - Options - Advanced - Network - Offline data there is localhost but with 0B size.

  • Gigabit network limited to 25MB/s by CPU. How to make it faster?

    - by netvope
    I have a Acer Aspire R1600-U910H with a nForce gigabit network adapter. The maximum TCP throughput of it is about 25MB/s, and apparently it is limited by the single core Intel Atom 230; when the maximum throughput is reached, the CPU usage is about 50%-60%, which corresponds to full utilization considering this is a Hyper-threading enabled CPU. The same problem occurs on both Windows XP and on Ubuntu 8.04. On Windows, I have installed the latest nForce chipset driver, disabled power saving features, and enabled checksum offload. On Linux, the default driver has checksum offload enabled. There is no Linux driver available on Nvidia's website. ethtool -k eth0 shows that checksum offload is enabled: Offload parameters for eth0: rx-checksumming: on tx-checksumming: on scatter-gather: on tcp segmentation offload: on udp fragmentation offload: off generic segmentation offload: off The following is the output of powertop when the network is idle: Wakeups-from-idle per second : 61.9 interval: 10.0s no ACPI power usage estimate available Top causes for wakeups: 90.9% (101.3) <interrupt> : eth0 4.5% ( 5.0) iftop : schedule_timeout (process_timeout) 1.8% ( 2.0) <kernel core> : clocksource_register (clocksource_watchdog) 0.9% ( 1.0) dhcdbd : schedule_timeout (process_timeout) 0.5% ( 0.6) <kernel core> : neigh_table_init_no_netlink (neigh_periodic_timer) And when the maximum throughput of about 25MB/s is reached: Wakeups-from-idle per second : 11175.5 interval: 10.0s no ACPI power usage estimate available Top causes for wakeups: 99.9% (22097.4) <interrupt> : eth0 0.0% ( 5.0) iftop : schedule_timeout (process_timeout) 0.0% ( 2.0) <kernel core> : clocksource_register (clocksource_watchdog) 0.0% ( 1.0) dhcdbd : schedule_timeout (process_timeout) 0.0% ( 0.6) <kernel core> : neigh_table_init_no_netlink (neigh_periodic_timer) Notice the 20000 interrupts per second. Could this be the cause for the high CPU usage and low throughput? If so, how can I improve the situation? The other computers in the network can usually transfer at 50+MB/s without problems. And a minor question: How can I find out what is the driver in use for eth0?

  • Visual Studio not recognizing "BuildStep"

    - by AmbiguousX
    I'm trying to add an automatic post-build trigger to run NDepend after an automated team build in TFS 2010. NDepend's website provided code for integrating this capability, and so I have pasted their code into my .csproj file where they said for it to go, but I receive errors on the build. The errors refer to two of the three "BuildStep" tags I have in the code snippet. The following two snippets are giving me errors: <BuildStep TeamFoundationServerUrl="$(TeamFoundationServerUrl)" BuildUri="$(BuildUri)" Message="Running NDepend analysis"> <Output TaskParameter="Id" PropertyName="StepId" /> </BuildStep> and <BuildStep TeamFoundationServerUrl="$(TeamFoundationServerUrl)" BuildUri="$(BuildUri)" Id="$(StepId)" Status="Failed" /> However, this code snippet is NOT throwing up any problems: <BuildStep TeamFoundationServerUrl="$(TeamFoundationServerUrl)" BuildUri="$(BuildUri)" Id="$(StepId)" Status="Succeeded" /> I just don't understand why one works fine and a nearly identically laid out BuildStep tag does not. Is there something simple that I'm just overlooking? EDIT: Here is how it looks all together, if this makes a difference: <Target Name="NDepend" > <PropertyGroup> <NDPath>c:\tools\NDepend\NDepend.console.exe</NDPath> <NDProject>$(SolutionDir)MyProject.ndproj</NDProject> <NDOut>$(TargetDir)NDepend</NDOut> <NDIn>$(TargetDir)</NDIn> </PropertyGroup> <Exec Command='"$(NDPath)" "$(NDProject)" /OutDir "$(NDOut)" /InDirs "$(NDIn)"'/> </Target> <Target Name="AfterBuild"> <BuildStep TeamFoundationServerUrl="$(TeamFoundationServerUrl)" BuildUri="$(BuildUri)" Message="Running NDepend analysis"> <Output TaskParameter="Id" PropertyName="StepId" /> </BuildStep> <PropertyGroup> <NDPath>c:\tools\NDepend\NDepend.console.exe</NDPath> <NDProject>$(SolutionRoot)\Main\src\MyProject.ndproj</NDProject> <NDOut>$(BinariesRoot)\NDepend</NDOut> <NDIn>$(BinariesRoot)\Release</NDIn> </PropertyGroup> <Exec Command='$(NDPath) "$(NDProject)" /OutDir "$(NDOut)" /InDirs "$(NDIn)"'/> <BuildStep TeamFoundationServerUrl="$(TeamFoundationServerUrl)" BuildUri="$(BuildUri)" Id="$(StepId)" Status="Succeeded" /> <OnError ExecuteTargets="MarkBuildStepAsFailed" /> </Target> <Target Name="MarkBuildStepAsFailed"> <BuildStep TeamFoundationServerUrl="$(TeamFoundationServerUrl)" BuildUri="$(BuildUri)" Id="$(StepId)" Status="Failed" /> </Target> EDIT: Added a bounty because I really need to get this going for my team. Thank you in advance!

  • Mercurial permament delete?

    - by Arnis L.
    I commit some 3rd party tools that i decided not to use afterwards and removed them from hg again. Thing that i dislike - they are still kept in history. Normally this is a good thing of course, but for this particular case - that's just a waste of space. What are options to intentionally mess around with hg repository history and weed it out?

  • Is MobiForms for Android worth investigating ?

    - by Alan B
    I'm working my way through the NotePad tutorial, and that's all fine - I'm not a Java programmer but it's close enough to C# (or vice versa) to make it easy to pick up. I'm surprised that there aren't any RAD tools for Android apart from Mobiforms. Is there anyone out there with experience of Mobiforms ?
