  • Money vs. Decimal vs. Float Performance issues (SQL data types for Currency value)?

    - by urz shah
    What data type should be selected in case of Currency value column in SQL server. I have read some where on web Working on customer implementations, we found some interesting performance numbers concerning the money data type. For example, when Analysis Services was set to the currency data type (from double) to match the SQL Server money data type, there was a 13% improvement in processing speed (rows/sec). Is it true??

  • How to pickle and unpickle objects with self-references and from a class with slots?

    - by EOL
    Is it possible to pickle an object from a class with slots, when this object references itself through one of its attributes? Here is a simple example: import weakref import pickle class my_class(object): __slots__ = ('an_int', 'ref_to_self', '__weakref__') def __init__(self): self.an_int = 42 self.ref_to_self = weakref.WeakKeyDictionary({self: 1}) # __getstate__ and __setstate__ not defined: how should this be done? if __name__ == '__main__': obj = my_class() # How to make the following work? obj_pickled = pickle.dumps(obj) obj_unpickled = pickle.loads(obj_pickled) # Self-references should be kept: print "OK?", obj_unpickled == obj_unpickled.ref_to_self.keys()[0]

  • jQuery: Hide/Display tabs (and its corresponding content) with check boxes

    - by Ricardo
    Hello, Well, this must be very simple to do for most of you, but I have no idea how to accomplish this. I have a set of tabs and on top of the tabs is a set of checkboxes ; each checkbox 'corresponds' to a tab. What I need is to be able to activate/deactivate each checkbox and have its corresponding tab (and the tab's content) hide/display. Here's my HTML: <div class="show-results-from"> <ul> <li>See results from:</li> <li> <label> <input type="checkbox" name="a" id="a"> Products &amp; Services <span>(16)</span></label> </li> <li> <label> <input type="checkbox" name="b" id="b"> Publications <span>(9)</span></label> </li> <li> <label> <input type="checkbox" name="c" id="c"> Other <span>(150)</span></label> </li> </ul> </div> <ul class="tabs"> <li><span rel="tabs1" class="defaulttab">Products &amp; Services</span></li> <li><span rel="tabs2">Publications</span></li> <li><span rel="tabs3">Other</span></li> </ul> <div class="tab-content" id="tabs1">content</div> <div class="tab-content" id="tabs2">content</div> <div class="tab-content" id="tabs3">content</div> Any help with this is greatly appreciated.

  • Write failed, errno 0

    - by EpsilonVector
    I have a client server situation in which I receive data using read(socket, char_buf, BUF_SIZE) and then try to write it into a log file using write(filefd, char_buf, strlen(char_buf)) Strangely enough this fails (write returns -1), and yet the errno is set to 0, and I can print the message, AND the log file descriptor works (I write to it before and after this command). What's going on?? (Working on Linux kernel 2.4 (homework))

  • Python/Django: log to console under runserver, log to file under Apache

    - by Justin Grant
    How can I send trace messages to the console (like print) when I'm running my Django app under manage.py runserver, but have those messages sent to a log file when I'm running the app under Apache? I reviewed Django logging and although I was impressed with its flexibility and configurability for advanced uses, I'm still stumped with how to handle my simple use-case. My apologies for not being able to find the answer elsewhere-- this is a newbie question I know.
