• [MSBuild] Is there a way to print a new-line when using <Message...> ?

  - by Nam Gi VU

  I wanna write but \n seems not to be working. What should I replace \n with? (I read in the books they said that to print @ and % we use %40 and %25, so I guess the should be a number for the new-line). Any suggestions? Please help!

• Inaccessible item using C++ inheritance

• Why can't I SELECT a parent field that doesn't have a child?

  (rest_branches) is the table of restaurants. (phone_numbers) is another table which contains the restaurants phone_numbers, and it has a field called (branch_id) which references the restaurant id.

• Referencing sheets with spaces

  - by user2250964

  I am having an issue with referencing the sheet name through =Branded!$A$1 Notation in VBA. For a while I have passed in simple sheet names like: Dim SheetName As String SheetName = "Pizza" ("=" & SheetName & "!$A$1") This has worked fine, but recently I passed in "Tier 1" and of course this notation broke. Is there any fix or workaround for this? It Think it's because of the space, the number or both....

• Is a string formatter that pulls variables from its calling scope bad practice?

  - by Eric

  I have some code that does an awful lot of string formatting, Often, I end up with code along the lines of: "...".format(x=x, y=y, z=z, foo=foo, ...) Where I'm trying to interpolate a large number of variables into a large string. Is there a good reason not to write a function like this that uses the inspect module to find variables to interpolate? import inspect def interpolate(s): return s.format(**inspect.currentframe().f_back.f_locals) def generateTheString(x): y = foo(x) z = x + y # more calculations go here return interpolate("{x}, {y}, {z}")

• java random percentages

  - by erw

  I need to generate n percentages (integers between 0 and 100) such that the sum of all n numbers adds up to 100. If I just do nextInt() n times, each time ensuring that the parameter is 100 minus the previously accumulated sum, then my percentages are biased (i.e. the first generated number will usually be largest etc.). How do I do this in an unbiased way?

• Stored Procedure in postgresql, multiple queries w/ agreggates.

  - by fenix

  I'm trying to write a store procedure that can take some input parameters (obviously), run multiple queries against those, taking the output from those and doing calculations, and from those calculations and the original queries, outputting a formatted text string like: Number of Rows for max(Z) matching condition x and y of total rows matching x (x&y/x*100). To explain the max(Z) bit, this will be the username field, it won't matter which actual entry is picked, because the where clause will filter the results by user id, is there a saner way to do this?

• Why is Private Accessor deprecated?

  - by user3918598

  It used to be the number one reason for us to choose MSTest from others that we could access and test private methods. Now that Private accessors are deprecated in Visual Studio 2012. Does anyone know why Microsoft make such decision? Is it because it's not a good practice to test private methods? Also, if I still need to unit test my private methods, how could I do that in VS 2012 and later versions?

• Unicode escaping in C/C++

  - by Geo

  Hi guys! I'm having a dispute with a colleague of mine. She says that the following: char* a = "\x000aaxz"; will/can be seen by the compiler as "\x000aa". I do not agree with her, as I think you can have a maximum number of 4 hex characters after the \x. Can you have more than 4 hex chars? Who is right here?

• Fast way to compute the minimal distance of two sets of k-dimensional vectors

  - by vrld

  I two sets of k-dimensional vectors, where k is around 500 and the number of vectors is usually smaller. I want to compute the (arbitrarily defined) minimal distance between the two sets. A naive approach would be this: (loop for a in set1 for b in set2 minimizing (distance a b)) However, this requires O(n² * distance) computations. Is there a faster way of doing this?

• MySQL: SUM in WHERE clause

  - by checcco

  Hi guys, I've got this table CREATE TABLE `subevents` ( `id` int(11) NOT NULL AUTO_INCREMENT, `title` varchar(150) DEFAULT NULL, `content` text, `class` tinyint(4) NOT NULL DEFAULT '1', PRIMARY KEY (`id`) ) ENGINE=MyISAM Each row can have a different value in the 'class' field. I'd like to select any number of rows, ordered randomly, as long as the sum of the values in the 'class' field is equal to 100. How could I accomplish it directly in the MySQL query without doing it later in PHP? Thanks everybody!
