  • Microsoft Generation 4 Datacenter using ITPACs

    - by Eric Nelson
    Microsoft is continuing to make significant investments in Datacenter technology and is focused on solving issues such as long lead times, significant up-front costs and over capacity. Enter the world of modular Datacenters and ITPACs – IT Pre-Assembled Components. In simple terms – air handling and IT units which are pre-assembled (looking somewhat like a container) and then installed on concrete bases. Each unit can hold  between 400 and 2500 servers (which means many more virtual machines depending on your density) Kevin Timmons’, manager of the datacenter operations team, just posted a great post digging into the detail One Small Step for Microsoft’s Cloud, Another Big Step for Sustainability which includes a short video on how we build one of these ITPACs. You might also want to check out this video from the PDC:

  • What if you could work on anything you wanted?

    - by red@work
    This week we've downed our tools and organised ourselves into small project teams or struck out alone. We're working on whatever we like, with whoever we like, wherever we like. We've called it Down Tools week and so far it's a blast. It all started a few months ago with an idea from Neil, our CEO. Neil wanted to capture the excitement, innovation, and productivity of Coding by the Sea and extend this to all Red Gaters working in Product Development. A brainstorm is always a good place to start for an "anything goes" project. Half of Red Gate piled into our largest meeting room (it's pretty big) armed with flip charts, post its and a heightened sense of possibility. An hour or so later our SQL Servery walls were covered in project ideas. So what would you do, if you could work on anything you wanted? Many projects are related to tools we already make, others are for internal product development use and some are, well, just something completely different. Someone suggested we point a web cam at the SQL Servery lunch queue so we can check it before heading to lunch. That one couldn't wait for Down Tools Week. It was up and running within a few days and even better, it captures the table tennis table too. Thursday is the Show and Tell - I am looking forward to seeing what everyone has come up with. Some of the projects will turn into new products or features so this probably isn't the time or place to go into detail of what is being worked on. Rest assured, you'll hear all about it! We're making a video as we go along too which will be up on our website as soon. In the meantime, all meetings are cancelled, we've got plenty of food in and people are being very creative with the £500 expenses budget (Richard, do you really need an iPad?). It's brilliant to see it all coming together from the idea stage to reality. Catch up with our progress by following #downtoolsweek on Twitter. Who knows, maybe a future Red Gate flagship tool is coming to life right now? By the way, it's business as usual for our customer facing and internal operations teams. Hmm, maybe we can all down tools for a week and ask Product Development to hold the fort? Post by: Alice Chapman

  • Destroying nested resources in restful way

    - by Alex
    I'm looking for help destroying a nested resource in Merb. My current method seems near correct, but the controller raise an InternalServerError during the destruction of the nested object. Here comes all the details concerning the request, don't hesitate to ask for more :) Thanks, Alex I'm trying to destroy a nested resources using the following route in router.resources :events, Orga::Events do |event| event.resources :locations, Orga::Locations end Which gives in jQuery request (delete_ method is a implementation of $.ajax with "DELETE"): $.delete_("/events/123/locations/456"); In the Location controller side, I've got: def delete(id) @location = Location.get(id) raise NotFound unless @location if @location.destroy redirect url(:orga_locations) else raise InternalServerError end end And the log: merb : worker (port 4000) ~ Routed to: {"format"=>nil, "event_id"=>"123", "action"=>"destroy", "id"=>"456", "controller"=>"letsmotiv/locations"} merb : worker (port 4000) ~ Params: {"format"=>nil, "event_id"=>"123", "action"=>"destroy", "id"=>"456", "controller"=>"letsmotiv/locations"} ~ (0.000025) SELECT `id`, `class_type`, `name`, `prefix`, `type`, `capacity`, `handicap`, `export_name` FROM `entities` WHERE (`class_type` IN ('Location') AND `id` = 456) ORDER BY `id` LIMIT 1 ~ (0.000014) SELECT `id`, `streetname`, `phone`, `lat`, `lng`, `country_region_city_id`, `location_id`, `organisation_id` FROM `country_region_city_addresses` WHERE `location_id` = 456 ORDER BY `id` LIMIT 1 merb : worker (port 4000) ~ Merb::ControllerExceptions::InternalServerError - (Merb::ControllerExceptions::InternalServerError)

  • What's the convention for extending Linq with set based helper operations

    - by Luke Rohde
    Hi All I might be vaguing out here but I'm looking for a nice place to put set based helper operations in linq so I can do things like; db.Selections.ClearTemporary() which does something like db.DeleteAllOnSubmit(db.Selections.Where(s => s.Temporary)) Since I can figure out how to extend Table<Selection> the best I can do is create a static method in partial class of Selection (similar to Ruby) but I have to pass in the datacontext like; Selection.ClearTemporary(MyDataContext) This kind of sucks because I have two conventions for doing set based operations and I have to pass the data context to the static class. I've seen other people recommending piling helper methods into a partial of the datacontext like; myDataContext.ClearTemporarySelections(); But I feel this makes the dc a dumping ground for in-cohesive operations. Surely I'm missing something. I hope so. What's the convention? TIA

  • NHibernate transactions randomly not rolled back

    - by cbp
    I have a suite of integration tests that run inside transactions. Sometimes it seems that NHibernate transactions are not being correctly rolled back. I can't work out what causes this. Here is a slightly simplified overview of the base class that these integration test fixtures run with: public class IntegrationTestFixture { private TransactionScope _transactionScope; private ConnectionScope _connectionScope; [TestFixtureSetUp] public virtual void TestFixtureSetUp() { var session = NHibernateSessionManager.SessionFactory.OpenSession(); CallSessionContext.Bind(session); _connectionScope = new ConnectionScope(); _transactionScope = new TransactionScope(); } [TestFixtureTearDown] public virtual void TestFixtureTearDown() { _transactionScope.Dispose(); _connectionScope.Dispose(); var session = CurrentSessionContext.Unbind(SessionFactory); session.Close(); session.Dispose(); } } A call to the TransactionScope's commit method is never made, therefore how is it possible that data still ends up in the database?

  • Best way to sort MySql results based on two columns and show results using pagination?

    - by understack
    I want to sort results set first based on one column and then based on second column. I know how to do it on server side. And then I want to show these results with pagination feature. Question: would it be better to do it on client side via ajax in jQuery? I'm using Zend Framework. Would Zend_Paginator module be useful in this scenario? Basically I want to evaluate all the possible ways? Which one would be best and/or simplest option given I'm using jQuery and Zend Framework?

  • Django: ordering by backward related field property

    - by Silver Light
    Hello! I have two models related one-to-many: a Post and a Comment: class Post(models.Model): title = models.CharField(max_length=200); content = models.TextField(); class Comment(models.Model): post = models.ForeignKey('Post'); body = models.TextField(); date_added = models.DateTimeField(); I want to get a list of posts, ordered by the date of the latest comment. If I would write a custom SQL query it would look like this: SELECT `posts`.`*`, MAX(`comments`.`date_added`) AS `date_of_lat_comment` FROM `posts`, `comments` WHERE `posts`.`id` = `comments`.`post_id` GROUP BY `posts`.`id` ORDER BY `date_of_lat_comment` DESC How can I do same thing using django ORM?

  • Axis2 webservice (aar archive) properties file

    - by XpiritO
    Hi there, guys. I'm currently developing a set of SOAP webservices over Axis2, deployed over a clustered WebLogic 10.3.2 environment. My webservices use some user settings that I want to be editable without the need for recompiling and regenerating the AAR archive. With this in mind, I chose to put them into a properties file that is loaded and consumed in runtime. Unfortunately, I'm having some questions about this: As far as I know, to achieve what I want, the only option is to put the properties file into the ../axis2/WEB-INF/classes directory of each one of the deployments (on each WebLogic instance) I currently have on my clustered configuration, and then load the file, as follows (or equivalent, this has not been verified for optimization): InputStreamReader fMainProp = new InputStreamReader(this.getClass().getResourceAsStream("myfile.properties")); Properties mainProp = new Properties(); mainProp.load(fMainProp); This is not as practical as I wanted it to be, because each time I want to alter some setting on the properties file, I have to edit each one of the files (deployed over different WebLogic instances) and there is a high probability of modifying one of these files without modifying the others. What I would like to know is if there is any (better) alternative to accomplish what I want, minimizing the potential conflict of configuration that is created by distributing and replicating the properties file through multiple WebLogic instances.

  • JAXB: @XmlTransient on third-party or external super class

    - by Phil
    Hi, I need some help regarding the following issue with JAXB 2.1. Sample: I've created a SpecialPerson class that extends a abstract class Person. Now I want to transform my object structure into a XML schema using JAXB. Thereby I don't want the Person XML type to appear in my XML schema to keep the schema simple. Instead I want the fields of the Person class to appear in the SpecialPerson XML type. Normally I would add the annotation @XmlTransient on class level into the Person code. The problem is that Person is a third-party class and I have no possibility to add @XmlTransient here. How can I tell JAXB that it should ignore the Person class without annotating the class. Is it possible to configure this externally somehow? Have you had the same problem before? Any ideas what the best solution for this problem would be?

  • Confusion over C++ new operator and classes

    - by Nils
    Hi all I created a simple class in C++ which has a private dynamic array. In the constructor I initialize the array using new and in the destructor I free it using delete. When I instantiate the class using Class a = Class(..); it works as expected, however it seems I cannot instantiate it using the new operator (Like Class *a = new Class(..);), I always get a segmentation fault. What I don't understand is when I should use new to instantiate a class and when just call the constructor or should it be possible to instantiate a class either with new or by just calling the constructor. float** A = new float*[3]; for (int i=0; i<3; i++) { A[i] = new float[3]; } A[0][0] = 3; A[0][1] = 3; A[0][2] = 4; A[1][0] = 5; A[1][1] = 6; A[1][2] = 7; A[2][0] = 1; A[2][1] = 2; A[2][2] = 3; Matrix *M = new Matrix(A, 3, 3); delete[] A; delete M; Below the class definition.. class Matrix { private: int width; int height; int stride; float* elements; public: Matrix(float** a, int n, int m); ~Matrix(); }; Matrix::Matrix(float** a, int n, int m) { // n: num rows // m: elem per rows elements = new float[n*m]; for (int i=0; i<n; i++) { for (int j=0; j<m; j++) { elements[i*n + j] = a[n][m]; } } } Matrix::~Matrix() { delete[] elements; }
