22,550,720 | 1 | Comparing Values of two lists and Printing to a file <p>I have a program that is supposed to be comparing the contents of a list to values returned by a tinter treeview and if the values do not match, writing the element of the list to a file. The idea is to allow the user to remove an element in the tree (which is populated by reading from a the same file I'm trying to write to). here is the code:</p> <pre><code> selected_book = info_box.focus() del_book = info_box.item(selected_book, 'values') title_file_clear = open("titles", 'w') author_file_clear = open("authors", 'w') title_file_clear.close() author_file_clear.close() title_file_3 = open("titles", "a") author_file_3 = open("authors", "a") for i in range(0,len(titles)): if titles[i] == del_book[0] is False: print(titles[i], file=title_file_3) for i in range(0,len(authors)): if authors[i] == del_book[1] is False: print(authors[i], file=author_file_3) title_file_3.close() author_file_3.close() </code></pre> <p>But all it seems to do is blank the files. (I do know this is not likely to be the most efficient piece of code, but I've been tweaking it for a while to try to get it to work)</p> |

37,117,740 | 0 | <p>Assuming that <code>resultSet</code> is a <code>List</code> implementation from the standard Java library, the answer to the "deep or shallow copy" question is "neither". <code>ListIterator</code>s of <code>List</code> classes in the standard Java library do not return a copy; they returns a <em>reference</em>, so you access the object stored in the <code>List</code>, not a copy of it.</p> <p>Since Java arrays are mutable, any modifications that your loop makes to <code>data</code> are done on the <code>Object[]</code> array stored inside the list.</p> <p>As <a href="http://stackoverflow.com/users/1221571/eran">Eran</a> correctly notes in his comment, since <code>List</code> and <code>ListIterator</code> are only interfaces, it is entirely conceivable to come up with an implementation that returns copies of list elements rather than references to actual elements. These copies could be deep or shallow, depending on your own implementation. However, list implementations supplied by Java library always return references to actual list elements.</p> |

For example calculate precise values of functions in some range, or for example apply some filter at image, or store text into db and read it from it or store prices of some products etc. This is not area where NN are needed. Of course it is possible theoretically to train NN to choose where and how to save data. Or to train it to accountancy. But for cases where big array of data need to be analyzed, and current methods doesn't feet NN can be option to consider. Or speech recognition, or buying some pictures which will become masterpieces in the future can be done with NN.</p> |

7,260,906 | 0 | Buildbot - Two Schedulers with one builder = Double checkin emails? <p>I have a buildbot running with two Schedulers - One triggered by code checkins and another triggered by content checkins; the former needs a much shorter treeStableTimer. Both of these Schedulers trigger the same builder, but what happens now is that everyone gets build notification mails twice for each checkin; once for the code scheduler and once for the content scheduler.</p> <p>For example, if the following checkins go in... CL# 1000 12:00pm user_a (code) CL# 1001 1:00pm user_b (content) ...we'd see a build fire off on CL#1000 and send build notification mail to user_a. Then, a build would fire off from CL#1001 and send build notification to user_a and user_b - user_a gets two notifications that his checkin succeeded, when he should only get one.</p> <p>I'd like to set things up so that we have two Schedulers, but when a builder triggers and sends email, it sends notification to the number of people who checked in since that builder's last build, not that Scheduler's last build. This seems straightforward conceptually, but I haven't seen anything on this in the docs or forums.</p> <p>What's the right way to do this? We do need different treeStableTimers on the same builder, and people need build mail notification when their build completes, regardless of which of the two Schedulers triggered the builder.</p> |

9,424,244 | 0 | <p>My answer <a href="http://stackoverflow.com/questions/9363827/building-gpl-c-program-with-cuda-module">to this recent question</a> likely describes what you need.</p> <p>A couple of additional notes:</p> <ol> <li>You don't need to compile your .cu to a .cubin or .ptx file. You need to compile it to a .o object file and then link it with the .o object files from your .cpp files compiled wiht g++.</li> <li>In addition to putting your cuda kernel code in cudaFunc.cu, you also need to put a C or C++ wrapper function in that file that launches the kernel (unless you are using the CUDA driver API, which is unlikely and not recommended). Also add a header file with the prototype of this wrapper function so that you can include it in your C++ code which needs to call the CUDA code. Then you link the files together using your standard g++ link line.</li> </ol> <p>I'm starting to repeat my <a href="http://stackoverflow.com/questions/9363827/building-gpl-c-program-with-cuda-module">other answer</a>, so I recommend just reading it. :)</p> |

21,859,548 | 0 | <p>My understanding is that you want to execute the onResize() function when the resize event is received. You seem to be a bit out of sync with how the document-ready stuff is intended to work -- and I recommend that you read some of the basic jquery tutorials -- but, basically, you want to use the function in $(function()....) to apply the event handler to the window after the document is fully loaded. </p> <p>Here, you seem to be -- mistakenly -- assuming that your running $(window).resize... after calling $(docyument).ready...would have waited until the .ready() function executed, but that's not how that works. The code that should be executed after the document reaches the fully-loaded state should go into the function parameter to $().</p> <p>Basically, you want to put your event handler assignment in the .ready() function like this:</p> <pre><code>$(function() { $(window).resize(onResize); }); </code></pre> |

Once 3 & 4 are both installed, the two use different project templates and the references to the MVC assemblies are specifically targetted at the correct versions.</p> <p>Beyond that, the web.configs of the two sites then determine the other assemblies that are used - and since they are seeded by the project templates they will be correct.</p> <p>Now, if you were asking about having 3 & 4 in the same <em>project</em>, that would be another story.
