• How to create a hover effect in a newsletter?

  - by Moak

  I'm creating a newsletter, and i want to have panels that change background-color on mouse over. Seeing as the newsletter wont have a head, I am defining all styles inline. I'm pretty sure most popular mail clients will block JS. So I was wondering if I can define a hover effect in the style attribute. Or is there any other solution to achieve this effect? Peace

• Get column name in jpa

  - by German

  Hi all, I have a query factory that takes a column name as an attribute in order to search for that column. Right now I'm passing the name of the column as a string, so it's kind of hardcoded. If the name of the column changes in the entity's annotation, that "hidden dependency" breaks up. Is there a way in jpa to retrieve the real name of the column and have it available at compile time, so I can use it in queries?

• I wrote a new X11 keyboard layout file, how do I get my system to recognize it?

  - by grimborg

  I like to configure my keys my way, so I wrote a keyboard symbols file and I put it in /usr/share/X11/xkb/symbols/cat I use it by running setxkbmap cat -variant dvorak (and it works), but it doesn't show up in the console configuration (dpkg-reconfigure console-setup) nor in the Gnome keyboard settings... nor anywhere else, so I have to run setxkbmap every time. I suppose that I have to register it somewhere, but where? Any hints? Thanks!

• 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!

• C struct memory layout?

  - by Eonil

  I have C# background. Very newbie to low level language like C. In C#, memory layout by compiler by default, and I have to specify some special attribute to override this behavior for exact layout. As I know, C does not re-align by default. But I heard there's a little re-aligning behavior which very hard to find. Can I know about C's memory layout behavior? (what should be re-aligned and not)

• Put objects which are decorated with [DataContract] into a StateServer?

  - by Dave

  Is there anyway to stick objects which are decorated with DataContract attributes but not decorated with Serializable attributes in to a SqlServer StateServer? In other words, I would prefer not having to decorate these objects with the Serializable attribute as I will also have to implement IXmlSerizable on all of these objects because they do not have empty contstructors, and non-public setters for properties.

• PHP's form bracket trick is to Django's ___?

  - by Matt

  In PHP you can create form elements with names like: category[1] category[2] or even category[junk] category[test] When the form is posted, category is automatically turned into a nice dictionary like: category[1] => "the input value", category[2] => "the other input value" Is there a way to do that in Django? request.POST.getlist isn't quite right, because it simply returns a list, not a dictionary. I need the keys too.

• how to import the attributes from one table to another in mysql

  - by user225269

  Is it possible to import the attributes of one table, then I put it into another table using a query in mysql? For example I have table1 with attributes lname, fname, mname And I want to put those attributes into table2. Is there any query that could do that? I'm imagining that the table2 has one attribute that could later be dropped so that it will be the same as table1.

• How to retrieve the content of <script src="myscript.ms"></script>

  - by mikl0

  if it was inline instead of src it would be easy to use innerHTML however it returns blank...so i assume the src attribute makes the content of myscript.ms not go into the dom as it normally does for inline script. How can I access the data in myscript.ms file short of using some internal browser extension method? Thanks.
