• Free Memory Occupied by Std List, Vector, Map etc

  - by Graviton

  Coming from a C# background, I have only vaguest idea on memory management on C++-- all I know is that I would have to free the memory manually. As a result my C++ code is written in such a way that objects of the type std::vector, std::list, std::map are freely instantiated, used, but not freed. I didn't realize this point until I am almost done with my programs, now my code is consisted of the following kinds of patterns: struct Point_2 { double x; double y; }; struct Point_3 { double x; double y; double z; }; list<list<Point_2>> Computation::ComputationJob(list<Point_3> pts3D, vector<Point_2> vectors) { map<Point_2, double> pt2DMap=ConstructPointMap(pts3D); vector<Point_2> vectorList = ConstructVectors(vectors); list<list<Point_2>> faceList2D=ConstructPoints(vectorList , pt2DMap); return faceList2D; } My question is, must I free every.single.one of the list usage ( in the above example, this means that I would have to free pt2DMap, vectorList and faceList2D)? That would be very tedious! I might just as well rewrite my Computation class so that it is less prone to memory leak. Any idea how to fix this?

• Hiding a button on pushed view and showing it when back to list view

  - by torr

  When I load my list view it has several blog posts and a refresh button on the top left. If I tap on a list item a view is pushed with the contents of that specific post. When this view is pushed in, the refresh button is hidden. But when I tap 'Back' to the parent list view, I'd like the refresh button to show (un-hide) - but it remains hidden. Any idea how to make this work? This is my View: Ext.require(['Ext.data.Store', 'MyApp.model.StreamModel'], function() { Ext.define('MyApp.view.HomeView', { extend: 'Ext.navigation.View', xtype: 'homepanel', requires: [ 'Ext.dataview.List', ], config: { title: 'Home', iconCls: 'home', styleHtmlContent: true, navigationBar: { items: [ { xtype: 'button', iconMask: true, iconCls: 'refresh', align: 'left', action: 'refreshButton', id: 'refreshButtonId' } ] }, items: { title: 'My', xtype: 'list', itemTpl: [ '<div class="post">', ... '</div>' ].join(''), store: new Ext.data.Store({ model: 'MyApp.model.StreamModel', autoLoad: true, storeId: 'stream' }), } } }); }); and my Controller: Ext.define('MyApp.controller.SingleController', { extend: 'Ext.app.Controller', config: { refs: { stream: 'homepanel' }, control: { 'homepanel list': { itemtap: 'showPost' } } }, showPost: function(list, index, element, record) { this.getStream().push({ xtype: 'panel', html: [ '<div class="post">', '</div>' ].join(''), scrollable: 'vertical', styleHtmlContent: true, }); Ext.getCmp('refreshButtonId').hide(); } });

• File Hierarchy system with a web application logic question: List searching

  - by molleman

  I need to search through a list of folders that could have more folders inside it, and add a new folder depending what folder is its parent.(the path is stored as a String for eg = "root/MyCom/home/") Then i fill in a field with a new folder name and add it to the final folder(eg "home/"). Below as you can see , I can navigate to the right location and add the new folder to a current folder, My trouble is that i cannot ensure that currentFolder element is placed back in the list it came from how could i add a folder to a list of folders, that could be within a list of folders,that could be within a list of folders and endless more? YFUser user = (YFUser)getSession().getAttribute(SESSION_USER); Folder newFolder = new Folder(); newFolder.setFolderName(foldername); // this is the path string (root/MyCom/home/) split in the different folder names String folderNames[] = folderLocationString.split("/"); int folderNamesLength = folderNames.length; Folder root = user.getRoot(); Folder currentFolder = root; for(int i=0;i<=folderNamesLength; i++){ // because root is folderNames[i] String folderName = folderNames[i++]; int currentFolderSize = currentFolder.getChildren.getSize(); for(int o=1; o<= currentFolderSize ; o++){ if(currentFolder.getChildren().get(o) instanceof Folder){ if(folderName.equals(currentFolder.getChildren().get(o).getFolderName())){ currentFolder = currentFolder.getChildren().get(o); if (i == counter){ //now i am inside the correct folder and i add it to the list of folders within it //the trouble is knowing how to re add this changed folder back to the list before it currentFolder.getChildren.add(newFolder); } } } } }

• hadoop implementing a generic list writable

  - by Guruprasad Venkatesh

  I am working on building a map reduce pipeline of jobs(with one MR job's output feeding to another as input). The values being passed around are fairly complex, in that there are lists of different types and hash maps with values as lists. Hadoop api does not seem to have a ListWritable. Am trying to write a generic one, but it seems i can't instantiate a generic type in my readFields implementation, unless i pass in the class type itself: public class ListWritable<T extends Writable> implements Writable { private List<T> list; private Class<T> clazz; public ListWritable(Class<T> clazz) { this.clazz = clazz; list = new ArrayList<T>(); } @Override public void write(DataOutput out) throws IOException { out.writeInt(list.size()); for (T element : list) { element.write(out); } } @Override public void readFields(DataInput in) throws IOException{ int count = in.readInt(); this.list = new ArrayList<T>(); for (int i = 0; i < count; i++) { try { T obj = clazz.newInstance(); obj.readFields(in); list.add(obj); } catch (InstantiationException e) { e.printStackTrace(); } catch (IllegalAccessException e) { e.printStackTrace(); } } } } But hadoop requires all writables to have a no argument constructor to read the values back. Has anybody tried to do the same and solved this problem? TIA.

• How to access elements in a complex list?

  - by Martin

  Hi, it's me and the lists again. I have a nice list, which looks like this: tmp = NULL t = NULL tmp$resultitem$count = "1057230" tmp$resultitem$status = "Ok" tmp$resultitem$menu = "PubMed" tmp$resultitem$dbname = "pubmed" t$resultitem$count = "305215" t$resultitem$status = "Ok" t$resultitem$menu = "PMC" t$resultitem$dbname = "pmc" tmp = c(tmp, t) t = NULL t$resultitem$count = "1" t$resultitem$status = "Ok" t$resultitem$menu = "Journals" t$resultitem$dbname = "journals" tmp = c(tmp, t) Which produces: str(tmp) List of 3 $ resultitem:List of 4 ..$ count : chr "1057230" ..$ status: chr "Ok" ..$ menu : chr "PubMed" ..$ dbname: chr "pubmed" $ resultitem:List of 4 ..$ count : chr "305215" ..$ status: chr "Ok" ..$ menu : chr "PMC" ..$ dbname: chr "pmc" $ resultitem:List of 4 ..$ count : chr "1" ..$ status: chr "Ok" ..$ menu : chr "Journals" ..$ dbname: chr "journals" Now I want to search through the elements of each "resultitem". I want to know the "dbname" for every database, that has less then 10 "count" (example). In this case it is very easy, as this list only has 3 elements, but the real list is a little bit longer. This could be simply done with a for loop. But is there a way to do this with some other function of R (like rapply)? My problem with those apply functions is, that they only look at one element. If I do a grep to get all "dbname" elements, I can not get the count of each element. rapply(tmp, function(x) paste("Content: ", x))[grep("dbname", names(rapply(tmp, c)))] Does someone has a better idea than a for loop? Thanx, Martin

• How to give points for each indices of list

  - by Eric Jung

  def voting_borda(rank_ballots): '''(list of list of str) -> tuple of (str, list of int) The parameter is a list of 4-element lists that represent rank ballots for a single riding. The Borda Count is determined by assigning points according to ranking. A party gets 3 points for each first-choice ranking, 2 points for each second-choice ranking and 1 point for each third-choice ranking. (No points are awarded for being ranked fourth.) For example, the rank ballot shown above would contribute 3 points to the Liberal count, 2 points to the Green count and 1 point to the CPC count. The party that receives the most points wins the seat. Return a tuple where the first element is the name of the winning party according to Borda Count and the second element is a four-element list that contains the total number of points for each party. The order of the list elements corresponds to the order of the parties in PARTY_INDICES.''' #>>> voting_borda([['GREEN','NDP', 'LIBERAL', 'CPC'], ['GREEN','CPC','LIBERAL','NDP'], ['LIBERAL','NDP', 'CPC', 'GREEN']]) #('GREEN',[4, 6, 5, 3]) list_of_party_order = [] for sublist in rank_ballots: for party in sublist[0]: if party == 'GREEN': GREEN_COUNT += 3 elif party == 'NDP': NDP_COUNT += 3 elif party == 'LIBERAL': LIBERAL_COUNT += 3 elif party == 'CPC': CPC_COUNT += 3 for party in sublist[1]: if party == 'GREEN': GREEN_COUNT += 2 elif party == 'NDP': NDP_COUNT += 2 elif party == 'LIBERAL': LIBERAL_COUNT += 2 elif party == 'CPC': CPC_COUNT += 2 for party in sublist[2]: if party == 'GREEN': GREEN_COUNT += 1 elif party == 'NDP': NDP_COUNT += 1 elif party == 'LIBERAL': LIBERAL_COUNT += 1 elif party == 'CPC': CPC_COUNT += 1 I don't know how I would give points for each indices of the list MORE SIMPLY. Can someone please help me? Without being too complicated. Thank you!

• Python opening a file and putting list of names on separate lines

  - by Jeremy Borton

  I am trying to write a python program using Python 3 I have to open a text file and read a list of names, print the list, sort the list in alphabetical order and then finally re-print the list. There's a little more to it than that BUT the problem I am having is that I'm supposed to print the list of names with each name on a separate line Instead of printing each name on a separate line, it prints the list all on one line. How can I fix this? def main(): #create control loop keep_going = 'y' #Open name file name_file = open('names.txt', 'r') names = name_file.readlines() name_file.close() #Open outfile outfile = open('sorted_names.txt', 'w') index = 0 while index < len(names): names[index] = names[index].rstrip('\n') index += 1 #sort names print('original order:', names) names.sort() print('sorted order:', names) #write names to outfile for item in names: outfile.write(item + '\n') #close outfile outfile.close() #search names while keep_going == 'y' or keep_going == 'Y': search = input('Enter a name to search: ') if search in names: print(search, 'was found in the list.') keep_going = input('Would you like to do another search Y for yes: ') else: print(search, 'was not found.') keep_going = input('Would you like to do another search Y for yes: ') main()

• Efficient way to maintain a sorted list of access counts in Python

  - by David

  Let's say I have a list of objects. (All together now: "I have a list of objects.") In the web application I'm writing, each time a request comes in, I pick out up to one of these objects according to unspecified criteria and use it to handle the request. Basically like this: def handle_request(req): for h in handlers: if h.handles(req): return h return None Assuming the order of the objects in the list is unimportant, I can cut down on unnecessary iterations by keeping the list sorted such that the most frequently used (or perhaps most recently used) objects are at the front. I know this isn't something to be concerned about - it'll make only a miniscule, undetectable difference in the app's execution time - but debugging the rest of the code is driving me crazy and I need a distraction :) so I'm asking out of curiosity: what is the most efficient way to maintain the list in sorted order, descending, by the number of times each handler is chosen? The obvious solution is to make handlers a list of (count, handler) pairs, and each time a handler is chosen, increment the count and resort the list. def handle_request(req): for h in handlers[:]: if h[1].handles(req): h[0] += 1 handlers.sort(reverse=True) return h[1] return None But since there's only ever going to be at most one element out of order, and I know which one it is, it seems like some sort of optimization should be possible. Is there something in the standard library, perhaps, that is especially well-suited to this task? Or some other data structure? (Even if it's not implemented in Python) Or should/could I be doing something completely different?

• using Python reduce over a list of pairs

  - by user248237

  I'm trying to pair together a bunch of elements in a list to create a final object, in a way that's analogous to making a sum of objects. I'm trying to use a simple variation on reduce where you consider a list of pairs rather than a flat list to do this. I want to do something along the lines of: nums = [1, 2, 3] reduce(lambda x, y: x + y, nums) except I'd like to add additional information to the sum that is specific to each element in the list of numbers nums. For example for each pair (a,b) in the list, run the sum as (a+b): nums = [(1, 0), (2, 5), (3, 10)] reduce(lambda x, y: (x[0]+x[1]) + (y[0]+y[1]), nums) This does not work: >>> reduce(lambda x, y: (x[0]+x[1]) + (y[0]+y[1]), nums) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "<stdin>", line 1, in <lambda> TypeError: 'int' object is unsubscriptable Why does it not work? I know I can encode nums as a flat list - that is not the point - I just want to be able to create a reduce operation that can iterate over a list of pairs, or over two lists of the same length simultaneously and pool information from both lists. thanks.

• How to get jQuery to find the first list-item, rather than all list-items?

  - by ricebowl

  I'm trying to implement a basic jQuery infinite carousel. As much for the learning process as for anything else (as a rule I'm not a fan of re-inventing wheels, but...I have to learn somehow, might as well start with the basics). I've managed to get the list to animate left happily enough, but I'm stuck when it comes to selecting the first element of the list. I've tried to use: $('ul#services > li:first'); $('ul#services > li:first-child'); $('ul#services > li').eq([0]); (xhtml below), In each case a console.log(first) (the var name used) returns all of the list-items. Am I doing something blatantly, and obviously, wrong? The eventual plan is to clone the first li, append it to the parent ul, remove the li from the list and allow the list to scroll infinitely. It's just a list of services rather than links so I'm not -at the moment- planning to have scroll or left/right functionality. Current xhtml: <div class="wrapper"> <ul id="services"> <!-- closing the `</li>` tags on the following line is to remove whitespace in the horizontal list, doesn't seem to make a difference to the jQuery from my own testing. --> <li>one</li ><li>two</li ><li>three</li ><li>four</li ><li>five</li ><li>six</li ><li>seven</li ><li>eight</li ><li>nine</li ><li>ten</li> </ul> </div>

• WCF operationcontract with List type unavailable in (Silverlight) client

  - by Dave

  This is the first time I have tried returning a List of data to a Silverlight client, so I'm having trouble getting the client to recognize this operationcontract. All others are fine. I have a method on the server called ReadOwFileData that needs to return a List. ReadOwFileDataCompletedEventArgs shows up in the Object Browser in the client, but not ReadOwFileDataAsync. What I want is similar to the tutorial here. The Dictionary collection type on the client is set to System.Collections.Generic.List. I tried deleting and recreating the service reference. Web.Config on the server is using basicHttpBinding. Here is the operationcontract on the server: [OperationContract] public List<OwFileData> ReadOwFileData(string OrderID) { DataClasses1DataContext db = new DataClasses1DataContext(); var dFileData = (from p in db.OwFileDatas where p.OrderID == OrderID select p).ToList(); List<OwFileData> x = new List<OwFileData>(dFileData); return x; } Incidently, this works fine: [OperationContract] public Customer GetShippingAndContactInfo(string login, string ordernum) { DataClasses1DataContext db = new DataClasses1DataContext(); Customer dInfo = (from p in db.Customers where p.Login == login select p).Single(); return dInfo; } I would like to read this data in the client and place it into an object I created called ObservableCollection. But that obviously can't happen until the client can see the method on the server. I do not know if this is an acceptable start, but this is what is on the client so far. The ReadOwFileDataAsync object is null: void populatefilesReceivedDataSource(string OrderID) { ArtUpload.ServiceReference1.UploadServiceClient client = new ArtUpload.ServiceReference1.UploadServiceClient(); var myList = client.ReadOwFileDataAsync(OrderID); // can I just itterate thru the list instead of 'binding' }

• C# WinForms populating TreeView from List<myObj>

  - by user743354

  I have this structure of classes: public class L3Message { public int Number { get; set; } public string MessageName { get; set; } public string Device { get; set; } public string Time { get; set; } public string ScramblingCode { get; set; } public List<Parameter> Parameters { get; set; } public L3Message() { Parameters = new List<Parameter>(); } } public class Parameter { public int numOfWhitespaces { get; set; } public string ParameterName { get; set; } public string ParameterValue { get; set; } public Parameter Parent { get; set; } public List<Parameter> SubParameters { get; set; } public Parameter() { SubParameters = new List<Parameter>(); } } So, as return type from one of my Methods I have List of L3Messages (List < L3Message ), and I need to map that to TreeView in WinForms (populate TreeView from that List). If possible, I would like to that in separate thread. How can I achieve that?

  Hello everybody, Using Microsoft VC# 2008 Express (little fact about me : non experience in c#, programskills further very beginnerlevel. This peace op program is to communicate with Zigbee switching walloutlets (switching, status info). and is downloaded from http://plugwiselib.codeplex.com/SourceControl/list/changesets The problem: NullRefferenceException was UnHandled private void port_DataReceived(object sender, SerialDataReceivedEventArgs e) {// Event for receiving data string txt = port.ReadExisting(); Console.WriteLine(txt); List<PlugwiseMessage> msg = reader.Read (Regex.Split (txt, "\r\n" )); //Console.WriteLine( msg ); DataReceived(sender, new System.EventArgs(), msg); VC# Marks the last line and says msg is empty. so i looked further. Msg come's from txt text is filled with "000002D200C133E1\r\nPutFifoUnicast 40 : Handle 722 :"< so it goes wrong in or reader.Read or in the List so i looked further: public List<PlugwiseMessage> Read(string[] serialData) { Console.WriteLine(serialData); List<PlugwiseMessage> output = new List<PlugwiseMessage>(); Console.WriteLine(output); Both (serialData) as (output); are empty. So can i assume that the problem is in: Read(string[] serialData) But now the questions, Is Read(string[] serialData) something which is a Windows.Refence or is is from a Method ? and IF this is so is this then reader.READ (how can i find this)? (answered my own question proberly)(method reader)(private PlugwiseReader reader) So why isn't is working trough the serialData ? or is it the List<PlugwiseMessage> part, but i have no idea how it is filled can sombody help me ?

• which default.list should i modify for default applications and what are the differences between the 2

  I would like to add miro to the default application GUI in system settings/default applications.I added ;miro.desktopnext to all rhythmbox.desktop entries eventually discovering if it was not added to audio/x-vorbis+ogg=rhythmbox.desktop as audio/x-vorbis+ogg=rhythmbox.desktop;miro.desktop it would not appear in the system settings/default applications drop down list for audio. I can find default.list in either /etc/gnome/defaults.list or /usr/share/applications/defaults.list modifying either gives me the same results.What is the difference and which is the correct list to modify?

• Remove hardware from "safely remove hardware" list on Windows 7

  - by ricsmania

  Hi, I have a USB wifi card (D-Link DWA-125) on a Windows 7 x64 computer. The problem is that the card appears on the "safely remove hardware" list, but I don't ever want to unplug it, so I would like to remove it from the list. So far I have only found solutions that mess with the registry (and don't really work properly) or that substitute the safely remove hardware with a third-party software. Or worse, hide the icon altogether. Yes, I do need the icon from USB drives and phones. So, is there a "clean" way to remove it from the list? Thanks.

• List files with last access date in linux

  - by kayaker243

  I'd like to clean up a server that my webmaster let turn into a mess. I know how to list all files not accessed within the last x days using find and -atime, but what I'm looking for is to come up with a listing of the last access date for files one level down in directory /foo: /foo/bar1.txt Dec 11, 2001 /foo/bar2.txt Nov 12, 2008 /foo/bar3.txt Jan 12, 2004 For folders one level down in directory /foo, list the date of the most recently accessed file within the directory (no limit on depth for identifying last access date) /foo/bar1/ Feb 13, 2012 /foo/bar2/ Oct 11, 2008 Where /foo/bar1/ has a file modified Jan 1, 1998 and Feb 13, 2012 and /foo/bar2/ has 30 files, most recent of which was accessed Oct 11, 2008. This question is similar to: http://stackoverflow.com/questions/5566310/how-to-recursively-find-and-list-the-latest-modified-files-in-a-directory-with-s but rather than the modification date, the date of interest is the last accessed date.

• (Apache) RedirectMatch regex to match all directories except those in my list

  - by dotben

  I need to 301 redirect all requests coming in for requests to http//server.com to be redirected to http//newserver.com unless the request is for an arbitary list of directories we are maintaining on the legacy server (eg server.com/foo or server.com/bar) I'm having a hard time working out how best to set this up and the regexs. EG, I need: http//server.com/page1 redirect to http//newserver.com/page1 http//server.com/dir1/page2 redirect to http//newserver.com/dir1/page2 http//server.com/foo to load as normal http//server.com/bar/baz.html to load as normal ... because 'foo' and 'bar' are in my list of legacy dirs. I'm wondering if the way to do this is to some how catch the matches in my list and then redirect anything else as a wildcard over to the new server -- but I can't make it work. Can anyone help me with some regex and rewrites for those please? Thanks (apologies for fudging the http:// in the urls, ServerFault thinks I'm posting hyperlinks and won't otherwise let me post this)

• Use apt-get source on a debian repo without using /etc/apt/source.list

  I'm trying to use apt-get source as a regular user on a debian squeeze system. I want to retrieve the sources for cyrus-imapd-2.4 from the testing/wheezy repository. apt-get source works without root privileges; however, it seems there is no way to get apt-get to fetch anything from a repository that is not in /etc/apt/sources.list. Is there any command line option, alternate sources.list file, environment variable that will get apt to work with a custom repository ? I do have root access so I could change the /etc/apt/sources.list, however I really do not want to do that for a number of reason.

• Understanding List formatting in MSWord

  - by John

  I've never understood how formatting works in MSWord for lists... it mostly just works but sometimes becomes incredibly stubborn about enforcing styles you don't want, especially when copy-pasting into a list and working with multiple, multi-layer lists. What are some good ways to understand how it works, so one can work with Word, instead of fighting against it? Here's an example... I want a list like: 1)first test CHECK: a)something b)another thing 2)another test CHECK: a)it works b)it doesn't crash I find Word really doesn't like this... I try creating one mini-list and copy pasting but typically the numbering on the sub-lists doesn't re-start automatically, etc. I'm using Word 2007 but I remember it being this way in earlier versions too.

• search solution to integrate community mailing-lists into a website on shared hosting

  - by Thomas Traub

  The community (300 members), cocktailnetwork, has a website, cocktailnetwork.eu and about ten mailing lists. We want to manage the mailing lists from inside the website (lists and subscribers) and link the list's informations with the member profiles on the site. We are on shared hosting. The community members use the lists to send mails to all other members / groups of members. They can subscribe / unsubscribe from a list. The administrators can in addition create / delete / modify lists. Right now I use ezmlm with QmailAdmin, the lists are completly seperated from the website. I could link the data via remote administration commands, but that's not very satisfactory, does not allow the creation of new lists and it's an deprecated feature of our hosting package, sooner or later we'll need to switch anyway. Do You know of an elegant solution for us ? Any web service with a good, stable API ? Thanks.

• How to list down hosts with nmap 5.51

  - by Wild Bill

  I was using nmap 5.21 with the -PN, -F and --reason flags in version 5.21. I was outputting the results to an XML file. It would list ALL hosts (say I gave it a /24 subnet to scan. I then updated to 5.51 and ran the exact same command, but it no longer lists down hosts, just ones that are up. Is there a new flag to list down hosts? OR did this get removed in 5.51? My full options are: -sS -n -PN -SV -F --reason I've also used and removed --open but it will not list down hosts in my XML output.

• Data Validation of a Comma Delimited List

  - by Brad

  I need a simple way of taking a comma seperated list in a cell, and providing a drop down box to select one of them. For Example, the cell could contain: 24, 32, 40, 48, 56, 64 And in a further cell, using Data Validation, I want to provide a drop-down list to select ONE of those values I need to do this without VBA or Macros please. Apolgies, I want this to work with Excel 2010 and later. I have been playing around with counting the number of commas in the list and then trying to split this into a number of rows of single numbers etc with no joy yet.

• Where is the list of available Windows locales?

  - by Richard Cotton

  If you open the Regional and Language Options (via Control Panel), and click on the Regional Options tab, then there is a drop down list of all the available locales. Where is this list populated from? (I want to compare the settings for each locale; I'm fine with how to do that, but I need a list of locale names to loop over.) EDIT: After browsing through my windows directory (should probably mention I'm using XP), the file C:\WINDOWS\system32\locale.nls looks like a plausible candidate, but it's a binary file. Is this what I should be looking at, and if so, how do I read it?
