• Testing in Scrum

  - by alex

  In Scrum it's a good idea to test frequently when iteration is finished at customer. But the question is what kind of test should I use when some of the prototype is done with customer? In my knowledge Acceptance test is ok when all the iteration is done - but not some part of it. Examples for the test plan would be helpful

• Python named print?

  - by Mark

  I know it's a really simple question, but I have no idea how to google it. how can I do print '<a href="%s">%s</a>' % (my_url) So that my_url is used twice? I assume I have to "name" the %s and then use a dict in the params, but I'm not sure of the proper syntax? just FYI, I'm aware I can just use my_url twice in the params, but that's not the point :)

• C#: How would you only draw certain ListView Items while in Virtual Mode?

  - by Jonathan Richter

  C#: How would you only draw certain ListView Items while in Virtual Mode? I am trying to create a filter-like feature to use in listview so that if the user selects an imageindex from 0-5, it will loop through the listview items and only make it so that the items in question with the correct image index will be displayed and the other items will be hidden. How would I go upon creating such a routine?

• Is learncpp.com good for beginners?

  - by Dream Lane

  In my search for a good, freely available resource that will teach me C++ I stumbled on http://www.learncpp.com/. My question is for intermediate to experienced C++ programmers... Does this site seem to be a good resource for a beginner to learn C++ from? I've gone through the first few section of the site, and I feel like I am starting to grasp the language, but being a beginner in C++ I really could be learning things all wrong and have no idea.

• c# bound Datagridview

  - by Jin

  I have a datagridview and it is bound to a stored procedure which returns a number of result columns. There is also a binding navigator with "Add New" button included. If I click "Add New" button, it creates a new row in datagridview automatically, and If I leave that new row by clicking a different row. datagridview invokes "commit" or something. so the question is How do I make datagridview not to commit adding a new row when I leave the cell?

• Python File Search Line And Return Specific Number of Lines after Match

  - by Simos Anderson

  I have a text file that has lines representing some data sets. The file itself is fairly long but it contains certain sections of the following format: Series_Name INFO Number of teams : n1 | Team | # | wins | | TeamName1 | x | y | . . . | TeamNamen1 | numn | numn | Some Irrelevant lines Series_Name2 INFO Number of teams : n1 | Team | # | wins | | TeamName1 | num1 | num2 | . where each section has a header that begins with the Series_Name. Each Series_Name is different. The line with the header also includes the number of teams in that series, n1. Following the header line is a set of lines that represents a table of data. For each series there are n1+1 rows in the table, where each row shows an individual team name and associated stats. I have been trying to implement a function that will allow the user to search for a Team name and then print out the line in the table associated with that team. However, certain team names show up under multiple series. To resolve this, I am currently trying to write my code so that the user can search for the header line with series name first and then print out just the following n1+1 lines that represent the data associated with the series. Here's what I have come up with so far: import re print fname = raw_input("Enter filename: ") seriesname = raw_input("Enter series: ") def findcounter(fname, seriesname): logfile = open(fname, "r") pat = 'INFO Number of teams :' for line in logfile: if seriesname in line: if pat in line: s=line pattern = re.compile(r"""(?P<name>.*?) #starting name \s*INFO #whitespace and success \s*Number\s*of\s*teams #whitespace and strings \s*\:\s*(?P<n1>.*)""",re.VERBOSE) match = pattern.match(s) name = match.group("name") n1 = int(match.group("n1")) print name + " has " + str(n1) + " teams" lcount = 0 for line in logfile: if line.startswith(name): if pat in line: while lcount <= n1: s.append(line) lcount += 1 return result The first part of my code works; it matches the header line that the person searches for, parses the line, and then prints out how many teams are in that series. Since the header line basically tells me how many lines are in the table, I thought that I could use that information to construct a loop that would continue printing each line until a set counter reached n1. But I've tried running it, and I realize that the way I've set it up so far isn't correct. So here's my question: How do you return a number of lines after a matched line when given the number of desired lines that follow the match? I'm new to programming, and I apologize if this question seems silly. I have been working on this quite diligently with no luck and would appreciate any help.

• Automatically reporting javascript errors to the developer

  - by Cine

  As most production environments we have setup something to send us a notification if there is an error in our web application. The problem is ofcourse that this only covers errors on the server side. My question to the community is: What are you doing about client side errors, especially in javascript? And what about other quality of service issues, such as slow processing and other things that might be due to the client machine?

• Loading external SWF's with Transparent Background

  - by alvincrespo

  Just to get some professional opinions, is it possible to load in an external SWF and set that SWF's background to transparent? This question has nothing to do with embedding the SWF in an HTML page. I already know that setting the WMODE to transparent will create a SWF with a transparent background in a browser.

• How do you efficiently generate a list of K non-repeating integers between 0 and an upper bound N

  - by tucuxi

  The question gives all necessary data: what is an efficient algorithm to generate a sequence of K non-repeating integers within a given interval. The trivial algorithm (generating random numbers and, before adding them to the sequence, looking them up to see if they were already there) is very expensive if K is large and near enough to N. The algorithm provided here seems more complicated than necessary, and requires some implementation. I've just found another algorithm that seems to do the job fine, as long as you know all the relevant parameters, in a single pass.

• Looking for similar projects: Iphone/Android + Google Maps + "external" database = sightseeing map

  - by sniurkst

  Hello, sorry, it's not exactly a programming question, but I am currently in a research state and looking for similar projects, so I could analyze them: It should be application to iPhone or Android or other mobile platform, where, basically, user can access map with "places of interest" and add it's own "place of interest" (with photo and description). Kind of, community generated sightseeing map. I know it is quite simple and not a groundbreaking idea, but my google-fu is quite weak and I can't find anything like that.
