  • Mongodb vs. Cassandra

    - by ming yeow
    I am evaluating what might be the best migration option. Currently, i am on a sharded mysql (horizontal partition), with most of my data stored in json blobs. I do not have any complex SQL queries( already migrated away after since I partitioned my db) Right now, it seems like both Mongodb and Cassandra would be likely options. My situation lots of reads in every query, less regular writes not worried about "massive" scalability more concerned about simple setup, maintenance and code minimize hardware/server cost

  • 'Microsoft.ACE.OLEDB.12.0' 64x Sql Server and 86x Office???

    - by Chris
    The error: OLE DB provider 'Microsoft.ACE.OLEDB.12.0' cannot be used for distributed queries because the provider is configured to run in single-threaded apartment mode. And the answers I'm seeing is a conflict between 64 bit Sql Server and 32 bit Office. Is there a way to run an openrowset on Excel into Sql Server? insert into dbo.FiscalCalendar select * from openrowset('Microsoft.ACE.OLEDB.12.0', 'Excel 12.0 Xml;Database=C:\Users\v-chrha\Desktop\fy11.xlsx;', 'Select * from [Sheet1]')

  • How should I proceed to upgrade from TFS2008 to TFS2010

    - by Stephane
    Hi, We have a TFS2008 server with multiple team projects (about 20) What is the best way to migrate to TFS2010 without losing the history. I believe there are 2 ways, correct me if I'm wrong: installing a fresh tfs2010 and importing the DB from TFS 2008 or in-place upgrade. What is your recommendation and why? Are there any issue I should be prepared to face? Any advice is welcome.

  • Simple implementation of N-Gram, tf-idf and Cosine similarity in Python

    - by seanieb
    I need to compare documents stored in a DB and come up with a similarity score between 0 and 1. The method I need to use has to be very simple. Implementing a vanilla version of n-grams (where it possible to define how many grams to use), along with a simple implementation of tf-idf and Cosine similarity. Is there any program that can do this? Or should I start writing this from scratch?

  • NFS issue: clients can mount shares as NFSv3 but not as NFSv4 -- or how to debug NFS?

    - by tdn
    Problem description I have a file server running Debian. On it I have a few NFS shares. When I mount the shares from a client using NFSv3 (mount.nfs 10.0.0.51:/exports/video /mnt -o vers=3,soft,intr,timeo=10), it works. However, I would like to use NFSv4 because of improved security and performance. When I try to mount an NFSv4 share on malbec the mount command just hangs and finally times out after 2 minutes. How do I make the clients mount the NFSv4 shares as NFSv4? How do I troubleshoot NFS? There is no information in the syslog on neither client nor server. What are any errors in my configuration? Facts: Server is corvina(10.0.0.51) Client is malbec(10.0.0.1) Malbec runs Ubuntu 12.04 Server runs Debian 7 wheezy Both are connected through 1 GbE LAN.

Lets say that the site has the following tables: Posts. Votes. Comments. What is the best strategy to use for it: Identity - which is more common. OR HiLo - which give best performance. Edit: if HiLo is the best, how the structure of the DB would be?

  • ASP.NET MVC 2: Updating a Linq-To-Sql Entity with an EntitySet

    - by Simon
    I have a Linq to Sql Entity which has an EntitySet. In my View I display the Entity with it's properties plus an editable list for the child entites. The user can dynamically add and delete those child entities. The DefaultModelBinder works fine so far, it correctly binds the child entites. Now my problem is that I just can't get Linq To Sql to delete the deleted child entities, it will happily add new ones but not delete the deleted ones. I have enabled cascade deleting in the foreign key relationship, and the Linq To Sql designer added the "DeleteOnNull=true" attribute to the foreign key relationships. If I manually delete a child entity like this: myObject.Childs.Remove(child); context.SubmitChanges(); This will delete the child record from the DB. But I can't get it to work for a model binded object. I tried the following: // this does nothing public ActionResult Update(int id, MyObject obj) // obj now has 4 child entities { var obj2 = _repository.GetObj(id); // obj2 has 6 child entities if(TryUpdateModel(obj2)) //it sucessfully updates obj2 and its childs { _repository.SubmitChanges(); // nothing happens, records stay in DB } else ..... return RedirectToAction("List"); } and this throws an InvalidOperationException, I have a german OS so I'm not exactly sure what the error message is in english, but it says something along the lines of that the entity needs a Version (Timestamp row?) or no update check policies. I have set UpdateCheck="Never" to every column except the primary key column. public ActionResult Update(MyObject obj) { _repository.MyObjectTable.Attach(obj, true); _repository.SubmitChanges(); // never gets here, exception at attach } I've read alot about similar "problems" with Linq To Sql, but it seems most of those "problems" are actually by design. So am I right in my assumption that this doesn't work like I expect it to work? Do I really have to manually iterate through the child entities and delete, update and insert them manually? For such a simple object this may work, but I plan to create more complex objects with nested EntitySets and so on. This is just a test to see what works and what not. So far I'm disappointed with Linq To Sql (maybe I just don't get it). Would be the Entity Framework or NHibernate a better choice for this scenario? Or would I run into the same problem?

  • How do I use sqlite3 PRAGMA user_version in Objective-c?

    - by mobibob
    I am trying to check the user_version of the sqlite DB. I have an admin tool to bump the version, but I don't understand the syntax of the pragma statement. I am expecting to test the value in an if-statement. Can someone provide a code sample? When I embed the pragma statement in my objective-c code, the compiler throws an error.
