  • Idiomatic way to do list/dict in Cython?

    - by ramanujan
    My problem: I've found that processing large data sets with raw C++ using the STL map and vector can often be considerably faster (and with lower memory footprint) than using Cython. I figure that part of this speed penalty is due to using Python lists and dicts, and that there might be some tricks to use less encumbered data structures in Cython. For example, this page (http://wiki.cython.org/tutorials/numpy) shows how to make numpy arrays very fast in Cython by predefining the size and types of the ND array. Question: Is there any way to do something similar with lists/dicts, e.g. by stating roughly how many elements or (key,value) pairs you expect to have in them? That is, is there an idiomatic way to convert lists/dicts to (fast) data structures in Cython? If not I guess I'll just have to write it in C++ and wrap in a Cython import.

  • String replace in C#

    - by ile
    I'd like to use this method to create user-friendly URL. Because my site is in Croatian, there are characters that I wouldn't like to strip but replace them with another. Fore example, this string: ŠÐCŽ šdccž needs to be: sdccz-sdccz So, I would like to make two arrays, one that will contain characters that are to be replaced and other array with replacement characters: string[] character = { "Š", "Ð", "C", "C", "Ž", "š", "d", "c", "c", "ž" }; string[] characterReplace = { "s", "d", "c", "c", "z", "s", "d", "c", "c", "z" }; Finally, this two arrays should be use in some method that will take string, find matches and replace them. In php I used preg_replace function to deal with this. In C# this doesn't work: s = Regex.Replace(s, character, characterReplace); Would appreciate if someone could help. Thanks

  • Overlay of multiple colors in ImageJ

    - by nico
    Hi everyone, I'm writing a little plugin for imageJ and I am drawing several regions as an overlay on the image. I'm using this code: ImagePlus imp = getImage(); Overlay ov = new Overlay(); for (int r=0; r<regions.length; r++) { ov.add(regions[r]); } imp.setOverlay(ov); Where regions is an array of Roi. This works as intended and draws the regions in the (hurting to my eyes) standard ImageJ cyan used for overlays. I would like to draw one particular region in another colour, but I cannot seem to find a way to do it. I found that you can change the colour of the whole overlay, but I need two colours in the same overlay. Any ideas? Thanks in advance nico

  • What is the underlying reason for not being able to put arrays of pointers in unsafe structs in C#?

    - by cons
    If one could put an array of pointers to child structs inside unsafe structs in C# like one could in C, constructing complex data structures without the overhead of having one object per node would be a lot easier and less of a time sink, as well as syntactically cleaner and much more readable. Is there a deep architectural reason why fixed arrays inside unsafe structs are only allowed to be composed of "value types" and not pointers? I assume only having explicitly named pointers inside structs must be a deliberate decision to weaken the language, but I can't find any documentation about why this is so, or the reasoning for not allowing pointer arrays inside structs, since I would assume the garbage collector shouldn't care what is going on in structs marked as unsafe. Digital Mars' D handles structs and pointers elegantly in comparison, and I'm missing not being able to rapidly develop succinct data structures; by making references abstract in C# a lot of power seems to have been removed from the language, even though pointers are still there at least in a marketing sense. Maybe I'm wrong to expect languages to become more powerful at representing complex data structures efficiently over time.

  • UserControl Behaviour on a Windows Form

    - by AK
    Hi, I have a usercontrol UC1 with a combobox and a button. From the constructor, after initializing all the controls, I am populating the combobox with an array of information brought from other class library. I have kept the UC1 on windows form. When I tried to open the form's designer I see some errors and a suggestion to rebuild to fix the errors. After searching over net I found that the logic of populating the combobox is the culprit. I changed the code with an additional check of null and the issue is fixed now. My question is, how am i able to see the same usercontrol seperatly in designer view, but not when i placed the UC1 on a form and trying to see the designer view for the form? The same combobox populating logic should affect the drawing of UC1 when I try to see it in designer view right? Thanks, AK.

  • F# working with DataReader

    - by mamu
    let getBytesData x = let len = reader.GetBytes(1, int64 0, null, 0, 0); // Create a buffer to hold the bytes, and then // read the bytes from the DataTableReader. let buffer : byte array = [||] reader.GetBytes(1, int64 0, buffer, 0, int32 len) |> ignore buffer let retVal = List [ while reader.Read() do yield (reader.GetString(0), getBytesData reader, reader.GetDateTime(2)) ] I have above code to read bytes[] from datareader. getBytesData function takes reader and returns bytes[] from reader. everything works fine but it getBytesData function is working very non-functional way. Is there any way i can optimize in F#? Sorry for kind of question, but i have started a new project on F# to squeeze all juice out of it, so trying to get each line most optimal way

  • best way to parse plain text file with a nested information structure

  • iTunes Visualization -- What type of code is it written in and what does that code look like?

    - by Christopher Altman
    Being a web developer, I know how event driven user interfaces are written, but do not have insight into other families of code (embedded software like automotive software, automation software on assembly lines, drivers, or the crawling lower-thirds on CNN, etc.) I was looking at the iTunes visualizer (example) and am curious: What code is used to write the visualizer? Objective C? Does it use Core Animation? What type of abstraction does that library offer? What does the code look like? Is it a list of mathematical equations for producing the crazy graphics? Is it a list of key frames with tweening? Is there an array of images, fractals, worm holes, flowers, sparkles, and some magic mixes them together. Or something totally different? I am not looking for a tutorial, just an understanding of how something very different than web development works. Oh yah, I know iTunes is closed source, so all of this is conjecture.

  • Problem with numbers

    - by StolePopov
    I am given a number N, and i must add some numbers from the array V so that they wil be equal. V is consisting of numbers that are all powers of 3: N = 17 S = 0 V = 1 3 9 27 81 .. I should add numbers from V to N and S in order to make them equal. The solution to the example above is : 17 + 1 + 9 = 27, 27, 1 and 9 are taken from V, a number from V can be taken only once, and when taken it's removed from V. I tried sorting V and then adding the biggest numbers from V to S until S has reached N, but it fails on some tests when it's like: N = 7 S = 0 V = 1 3 9 27 So the solution will be: 7 + 3 = 9 + 1 In examples like this i need to add numbers both to N and S, and also select them so they become equal. Any idea of solving this ? Thanks.

  • Strange PHP reference bug

    - by Roland Soós
    Hello, I have a really strange bug with my PHP code. I have a recursive code which build up a menu tree with object and one of my customers server can't make it work.

  • Asking facebook for data of multiple users in single request using FB.api

    - by gruszczy
    I need to get basic user data from Facebook using FB.api('/<some_id>/'). This works well, but is slow, since I need to ask for every id separately and make several calls to facebook. Is there any way to gather all ids and ask for them in single request and get an array? EDIT I am not asking for user friends. I am actually trying to gather friends' friends of a user and that's something Facebook doesn't provide, that's why I am using graph.facebook.com/<id>/ rather than graph.facebook.com/me/friends. I don't want friends, I'd like to do something like this: graph.facebook.com/<id1>,<id2>,<id3>,../

  • Recording/Reading C doubles in the IEEE 754 interchange format

    - by rampion
    So I'm serializing a C data structure for cross-platform use, and I want to make sure I'm recording my floating point numbers in a cross-platform manner. I had been planning on just doing char * pos; /*...*/ *((double*) pos) = dataStructureInstance->fieldWithOfTypeDouble; pos += sizeof(double); But I wasn't sure that the bytes would be recorded in the char * array in the IEEE 754 interchange format. I've been bitten by cross-platform issues before (endian-ness and whatnot). Is there anything I need to do to a double to get the bytes in interchange format?

  • Cocoa NSOutlineView bug - [NSCFTimer copyWithZone:]: unrecognized selector sent to instance

    - by Circle
    I'm using an NSOutlineView with the function - (BOOL)outlineView:(NSOutlineView *)outlineView isGroupItem:(id)item defined so it gives the group row GUI look. When I add a root item, it works fine. When I add an item to root's child array and expand it, it works fine. If I contract the item though, the following error is logged: [NSCFTimer copyWithZone:]: unrecognized selector sent to instance I also get an EXC_BAD_ACCESS error if the app window is deactivated by switching to another app. I used the debugger to try to find where I might have made an error in one of my functions, but the stack trace only shows functions I did not create (RunCurrentEventLoopInMode, CFRunLoopRunSpecific, handleWindowNeedsDisplay, etc.) Does anyone have any idea where my error(s) might be?

  • Select Box not filling properly in rails

    - by CaptnCraig
    I am creating a select box for a form using this in _form.html.erb <%= f.select(:category_id,options_for_select(@cats)) %> @cats is an array created in my controller like this: @cats = [] categories.each do |c| @cats.push([c.full_name,c.id]) end The select box is properly filled, and the selected foreign key is even properly saved to the database. The problem is, when I come back in my edit action, the select box is moved back to the first item in the list, not the one corresponding to category_id. Reading the documentation it seems like this should just magically work. How do I get it to select the proper value?

  • Dynamic type for List<T>?

    Hi All, I've got a method that returns a List for a DataSet table public static List<string> GetListFromDataTable(DataSet dataSet, string tableName, string rowName) { int count = dataSet.Tables[tableName].Rows.Count; List<string> values = new List<string>(); // Loop through the table and row and add them into the array for (int i = 0; i < count; i++) { values.Add(dataSet.Tables[tableName].Rows[i][rowName].ToString()); } return values; } Is there a way I can dynamically set the datatype for the list and have this one method cater for all datatypes so I can specify upon calling this method that it should be a List<int or List<string> or List<AnythingILike>? Also, what would the return type be when declaring the method? Thanks in advance, Brett

  • Facebook Graph and PHP API

    I've been working at this for a few hours, but the poor documentation is of no help.

    What would be the proper way to explode a COM object for debugging? I have a 3rd party function that returns a multilevel object. The documentation is non existant, so I'd like to be able to echo everything out of the object or debug it in Komodo IDE. Komodo just says Object and nothing else. Maybe convert to array? I know some of the existing options such as $com->Status, but there are more variables returned that I'd like to know what they are.

  • Assign a Custom Global Pseudo Variable in Code Igniter

    - by Fábio Antunes
    Hello As you probably all know Code Igniter can assign pseudo variables using the Parser library, but you also know that if we want to assign a Pseudo Variable to use it in a View, we have to do it in every do it in every controller that loads those views with the pseudo variables. I would like to know if Code Igniter 1.7.2 has some way that i can assign a Global Pseudo variable (like the pseudo variables from the Benchmarking Class). The pseudo variables i want, would have simple data mostly returned from the $config array in the config.php file. If some could help me with that. Regards.

  • Javascript regex only matching entire url as typing

    - by dt
    I'm trying to use javascript to find all URLs in a textarea as the person is typing (onkeyup). The problem that I'm having is in finding a regex to match the entire URL, I need it only to match all the URL's in the text area that are complete URLs. All of the existing regex expressions that I find through Google and through my own experiementing seem to match as soon as the user has typed the first part of the pattern. So, for example, if I'm typing and then start to type http://w, all of a sudden, it will match. I need to find a regex that will match and return an array of all the urls that are in the textarea, while also not matching unless the person has completed typing the full URL. Hopefully that makes sense! Thank you!

  • Next month, same day in PHP

    - by Guillermo
    I got a last time (and urgent) requeriment of an "event" that needs to be scheduled the same day of every month. Say of you set the start date on the 1st May you should get the next events on the 1st of Jun, 1 Jul etc. The problem comes with a start date on the 31st (the next ones could be 30 or 28 depending on the month) Considering that there are months with different numbers of days (28,30,31) depending on the month itself and the year... what would ba an easy way to setup this? Consider the following (and flawed) nextmonth function: $events = array() function nextmonth($date) { return $date+(60*60*24*30); } $curr = $start; while($curr < $end) { $events[ = $curr; $curr = nextmonth($curr); } Edited to add: The problem for me is, simply enought, is to solve what the number of days of any given month is and thus get the next corresponding date..

  • Understanding how to inject object dependencies

    - by Hans
    I have an object that loads an instance of another object in a method. $survey = new survey; $question = new question($survey); $question-load($question_id); class question { public function __construct(&$survey) { $this-survey = $survey; } public function load ($id) { // now a question is loaded // want to load the survey that this question is in $this->survey->load($this->get('survey_id')); // ** survey_id is a field in the questions table // now $this->survey object has all the info about the survey this question is in } private function get($name) { // returns $name, if isset() from array that load() sets } } This is frying my brain, though, because it seems like $survey should come into $response already being a complete object. But, how do I do that, if I don't know what survey_id to load until I'm in the object? I am revamping a site and the most complex part is littered with this issue. TIA - Hans.
