• Are fragments of hashes collision-resistent?

  - by Mark

  Let me see if someone would mind clearing up this elementary point about md5 and hashing. If you only use the first 4 bytes of an md5 hash, would that mean theoretically only 1 in 255^4 chance of collision. iow is that the intention with it (and other hash algorithms) - that you only have to use a small portion of the returned hash (say the hash is of a file of some size).

• Django admin - remove field if editing an object

  - by John McCollum

  I have a model which is accessible through the Django admin area, something like the following: # model class Foo(models.Model): field_a = models.CharField(max_length=100) field_b = models.CharField(max_length=100) # admin.py class FooAdmin(admin.ModelAdmin): pass Let's say that I want to show field_a and field_b if the user is adding an object, but only field_a if the user is editing an object. Is there a simple way to do this, perhaps using the fields attribute? If if comes to it, I could hack a JavaScript solution, but it doesn't feel right to do that at all!

• How can I assure a class to have a static property by using interface or abstract?

  - by burak ozdogan

  Hi, I have one abstract class -let's say myBase. And I want all the classes derived from myBase to have one static field called public static List<string> MyPArameterNames { get {return _myParameterNames;} } So, every child class can tell what parameter names it uses; I want static because I do not want to create an instance just for this.

• Getting indices of most recent set of numbers in an array in Matlab?

  - by user2539781

  Let's say I have an array in Matlab: x = [1 1 1 2 2 2 3 3 3 3 2 2 3 3 3 1 1 1 1 1 2 2 2 2 3 3 3] I want the indices of the most recent set of consecutive '1's. In this case, I want the answer: answer = [16 17 18 19 20] % (which should correspond to the last sequence of 1's) I need an automated way to do this in Matlab, that will work with any size arrays, always giving me the indices for the last set of consecutive 1s. Any suggestions?

• Remove results below a certain score threshold in Solr/Lucene?

  - by snickernet

  Hi Guys, Is there a built-in functionalities in solr/lucene to filter the results if they fall below a certain score threshold? Let's say if I provide a score threshold of .2, then all documents with score less than .2 will be removed from my results. My intuition is that this is possible by updating/customizing solr or lucene. Could you point me to right direction on how to do this? Thanks in advance!

• SQLAlchemy: an efficient/better select by primary keys?

  - by hadrien

  Yet another newbie question.. Let's say I have an user table in declarative mode: class User(Base): __tablename__ = 'user' id = Column(u'id', Integer(), primary_key=True) name = Column(u'name', String(50)) When I have a list of users identifiers, I fetch them from db with: user_ids = [1, 2, 3, 4, 5] users = Session.query(User).filter(User.id.in_(user_ids)).all() I dislike using in_ because I think I learned it has bad performance on indexed fields (is that true/false?). Anyway, is there a better way doing that query? Thanks!
