  • Writing white space to CSV fields in Python?

    - by matt
    When I try to write a field that includes whitespace in it, it gets split into multiple fields on the space. What's causing this? It's driving me insane. Thanks data = open("file.csv", "wb") w = csv.writer(data) w.writerow(['word1', 'word2']) w.writerow(['word 1', 'word2']) data.close() I'll get 2 fields(word1,word2) for first example and 3(word,1,word2) for the second.

  • Handing over FaceBook SessionKey from iPhone to PHP

    - by Stefan Mayr
    Hi! Users authenticate normally on my iPhone app, and the permission for publish_stream is requested correctly. When the user want to post something on his wall, the text is transmitted to my backend and the backend posts it (with the transmitted session key) to the users facebook wall. The first post is always possible but at the second, the response is: "The user hasn't authorized the application to perform this action" But I was already able to post some seconds ago. What is wrong? Best Steve

  • Advanced SQL query with lots of joins

    - by lund.mikkel
    Hey fellow programmers Okay, first let me say that this is a hard one. I know the presentation may be a little long. But I how you'll bare with me and help me through anyway :D So I'm developing on an advanced search for bicycles. I've got a lot of tables I need to join to find all, let's say, red and brown bikes. One bike may come in more then one color! I've made this query for now: SELECT DISTINCT p.products_id, #simple product id products_name, #product name products_attributes_id, #color id pov.products_options_values_name #color name FROM products p LEFT JOIN products_description pd ON p.products_id = pd.products_id INNER JOIN products_attributes pa ON pa.products_id = p.products_id LEFT JOIN products_options_values pov ON pov.products_options_values_id = pa.options_values_id LEFT JOIN products_options_search pos ON pov.products_options_values_id = pos.products_options_values_id WHERE pos.products_options_search_id = 4 #code for red OR pos.products_options_search_id = 5 #code for brown My first concern is the many joins. The Products table mainly holds product id and it's image and the Products Description table holds more descriptive info such as name (and product ID of course). I then have the Products Options Values table which holds all the colors and their IDs. Products Options Search is containing the color IDs along with a color group ID (products_options_search_id). Red has the color group code 4 (brown is 5). The products and colors have a many-to-many relationship managed inside Products Attributes. So my question is first of all: Is it okay to make so many joins? Is i hurting the performance? Second: If a bike comes in both red and brown, it'll show up twice even though I use SELECT DISTINCT. Think this is because of the INNER JOIN. Is this possible to avoid and do I have to remove the doubles in my PHP code? Third: Bikes can be double colored (i.e. black and blue). This means that there are two rows for that bike. One where it says the color is black and one where is says its blue. (See second question). But if I replace the OR in the WHERE clause it removes both rows, because none of them fulfill the conditions - only the product. What is the workaround for that? I really hope you will and can help me. I'm a little desperate right now :D Regards Mikkel Lund

  • How to insert date in sqlite through java.

    - by dimitar
    Hello guys, I want to make a database that will hold a date in it(SQLite). Now first to ask is what is the right syntax to declare a date column. The second i want to know is how to insert date in it after that. And the third thing i want to know is how to select dates between, for example to select all rows which contain date between 01/05/2010 and 05/06/2010. Thank you

  • Collision point of 2 curves in a 3d-room

    - by Frank
    Hello, i am programming a small game for quite some time. We started coding a small FPS-Shooter inside of a project at school to get a bit experience using directX. I dont know why, but i couldnt stop the project and started programming at home aswell. At the moment i am trying to create some small AI. Of cause thats definatlly not easy, but thats my personal goal anyways. The topic could prolly fill multiple books hehe. I've got the walking part of my bots done so far. They walk along a scriped path. I am not working on the "aiming" of the bots. While programming that i hit on some math problem i couldnt solve yet. I hope of your input on this to help me get further. Concepts, ideas and everything else are highly appreciated. Problem: Calculate the position (D3DXVECTOR3) where the curve of the projectile (depends on gravity, speed), hit the curved of the enemys walking path (depends on speed). We assume that the enemy walks in a constant line. Known variables: float projectilSpeed = 2000 m/s //speed of the projectile per second float gravitation = 9.81 m/s^2 //of cause the gravity lol D3DXVECTOR3 targetPosition //position of the target stored in a vector (x,y,z) D3DXVECTOR3 projectilePosition //position of the projectile D3DXVECTOR3 targetSpeed //stores the change of the targets position in the last second Variabledefinition ProjectilePosition at time of collision = ProjectilePos_t TargetPosition at time of collision = TargetPos_t ProjectilePosition at time 0, now = ProjectilePos_0 TargetPosition at time 0, now = TargetPos_0 Time to impact = t Aim-angle = theta My try: Found a formular to calculate "drop" (Drop of the projectile based on the gravity) on Wikipedia: float drop = 0.5f * gravity * t * t The speed of the projectile has a horizontal and a vertical part.. Found a formular for that on wikipedia aswell: ProjectilVelocity.x = projectilSpeed * cos(theta) ProjectilVelocity.y = projectilSpeed * sin(theta) So i would assume this is true for the projectile curve: ProjectilePos_t.x = ProjectilePos_0.x + ProjectileSpeed * t ProjectilePos_t.y = ProjectilePos_0.y + ProjectileSpeed * t + 0.5f * gravity * t * t ProjectilePos_t.z = ProjectilePos_0.z + ProjectileSpeed * t The target walk with a constant speed, so we can determine his curve by this: TargetPos_t = TargetPos_0 + TargetSpeed * D3DXVECTOR3(t, t, t) Now i dont know how to continue. I have to solve it somehow to get a hold on the time to impact somehow. As a basic formular i could use: float time = distanz / projectileSpeed But that wouldnt be truly correct as it would assume a linear "Trajectory". We just find this behaivor when using a rocket. I hope i was able to explain the problem as much as possible. If there are questions left, feel free to ask me! Greets from germany, Frank

  • Problem loading java properties

    - by markovuksanovic
    I am trying to load properties from a file (test.properties) The code I use is as follows: URL url = getClass().getResource("../resources/test.properties"); properties.load(url.openStream()); But when executing the second line I get a NPE. (null pointer exception) I'm not sure what's wrong here... I have checked that the file exists at the location where URL points to... Any help is appreciated....

  • a script translatable to JavaScript with callback-hell automatic avoider :-)

    - by m1uan
    I looking for "translator" for JavaScript like already is CoffeScript, which will be work for example with forEach (inspired by Groovy) myArray.forEach() -> val, idx { // do something with value and idx } translate to JavaScript myArray.forEach(function(val, idx){ // do something with value and idx }); or something more usefull... function event(cb){ foo()-> err, data1; bar(data1)-> err, data2; cb(data2); } the method are encapsulated function event(cb){ foo(function(err,data1){ bar(data1, function(err, data2) { cb(data2); }); }); } I want ask if similar "compiler" to JavaScript like this even better already doesn't exists? What would be super cool... my code in nodejs looks mostly like this :-) function dealer(cb){ async.parallel([ function(pcb){ async.watterfall([function(wcb){ first(function(a){ wcb(a); }); }, function(a, wcb){ thirt(a, function(c){ wcb(c); }); fourth(a, function(d){ // dealing with “a” as well and nobody care my result }); }], function(err, array_with_ac){ pcb(array_with_ac); }); }, function(pcb){ second(function(b){ pcb(b);}); }], function(err, data){ cb(data[0][0]+data[1]+data[0][1]); // dealing with “a” “b” and “c” not with “d” }); } but, look how beautiful and readable the code could be: function dealer(cb){ first() -> a; second() -> b; third(a) -> c; // dealing with “a” fourth(a) -> d; // dealing with “a” as well and nobody care about my result cb(a+b+c); // dealing with “a” “b” and “c” not with “d” } yes this is ideal case when the translator auto-decide, method need to be run as parallel and method need be call after finish another method. I can imagine it's works Please, do you know about something similar? Thank you for any advice;-)

  • Why sockets does not die when server dies? Why socket dies when server is alive?

    - by Roman
    I try to play with sockets a bit. For that I wrote very simple "client" and "server" applications. Client: import java.net.*; public class client { public static void main(String[] args) throws Exception { InetAddress localhost = InetAddress.getLocalHost(); System.out.println("before"); Socket clientSideSocket = null; try { clientSideSocket = new Socket(localhost,12345,localhost,54321); } catch (ConnectException e) { System.out.println("Connection Refused"); } System.out.println("after"); if (clientSideSocket != null) { clientSideSocket.close(); } } } Server: import java.net.*; public class server { public static void main(String[] args) throws Exception { ServerSocket listener = new ServerSocket(12345); while (true) { Socket serverSideSocket = listener.accept(); System.out.println("A client-request is accepted."); } } } And I found a behavior that I cannot explain: I start a server, than I start a client. Connection is successfully established (client stops running and server is running). Then I close the server and start it again in a second. After that I start a client and it writes "Connection Refused". It seems to me that the server "remember" the old connection and does not want to open the second connection twice. But I do not understand how it is possible. Because I killed the previous server and started a new one! I do not start the server immediately after the previous one was killed (I wait like 20 seconds). In this case the server "forget" the socket from the previous server and accepts the request from the client. I start the server and then I start the client. Connection is established (server writes: "A client-request is accepted"). Then I wait a minute and start the client again. And server (which was running the whole time) accept the request again! Why? The server should not accept the request from the same client-IP and client-port but it does!

  • File sizing issue in DOS/FAT

    - by Heather
    I've been tasked with writing a data collection program for a Unitech HT630, which runs a proprietary DOS operating system that can run executables compiled for 16-bit MS DOS with some restrictions. I'm using the Digital Mars C/C++ compiler, which is working well thus far. One of the application requirements is that the data file must be human-readable plain text, meaning the file can be imported into Excel or opened by Notepad. I'm using a variable length record format much like CSV that I've successfully implemented using the C standard library file I/O functions. When saving a record, I have to calculate whether the updated record is larger or smaller than the version of the record currently in the data file. If larger, I first shift all records immediately after the current record forward by the size difference calculated before saving the updated record. EOF is extended automatically by the OS to accommodate the extra data. If smaller, I shift all records backwards by my calculated offset. This is working well, however I have found no way to modify the EOF marker or file size to ignore the data after the end of the last record. Most of the time records will grow in size because the data collection program will be filling some of the empty fields with data when saving a record. Records will only shrink in size when a correction is made on an existing entry, or on a normal record save if the descriptive data in the record is longer than what the program reads in memory. In the situation of a shrinking record, after the last record in the file I'm left with whatever data was sitting there before the shift. I have been writing an EOF delimiter into the file after a "shrinking record save" to signal where the end of my records are and space-filling the remaining data, but then I no longer have a clean file until a "growing record save" extends the size of the file over the space-filled area. The truncate() function in unistd.h does not work (I'm now thinking this is for *nix flavors only?). One proposed solution I've seen involves creating a second file and writing all the data you wish to save into that file, and then deleting the original. Since I only have 4MB worth of disk space to use, this works if the file size is less than 2MB minus the size of my program executable and configuration files, but would fail otherwise. It is very likely that when this goes into production, users would end up with a file exceeding 2MB in size. I've looked at Ralph Brown's Interrupt List and the interrupt reference in IBM PC Assembly Language and Programming and I can't seem to find anything to update the file size or similar. Is reducing a file's size without creating a second file even possible in DOS?

  • How to refactor T-SQL stored procedure encapsulating it's parameters to a class

    - by abatishchev
    On my SQL Server 2008 I have a stored procedure with a large number of parameters. The first part of them is used in every call and parameters from the second part are used rarely. And I can't move the logic to two different stored procedures. Is there a way to encapsulate all this parameters to a class or struct and pass it as a stored procedure parameter? Can I use SQL CLR. Are there other ways?

  • Deallocation doesn't free mem. in Windows/C++ Application

    - by Paul Baumer
    Hi, My Windows/C++ application allocates ~1Gb of data in memory with the new operator and processes this data. The data is deleted after processing. I noticed that if I run the processing again without exiting the application, the second call to "new" operator to allocate ~1gb of data fails. I would expect Windows to deliver back the memory again. Could this be managed in a better way with some other win32 calls etc. ? Thanks, Paul

  • Latex: index of symbols

    - by Daniel
    I want to create an index of symbols or notation, similar to the usual index one obtains with makeindex. I have gotten this to work, using the glossaries package. However, just as in the usual index, I would like to get two columns in the index of symbols, while glossaries puts everything under each other. Commands like twocolumn or multicol also do not work, because then the second column starts higher than the first, above the title of the index of symbols. Any suggestions?

    What features do you want to see in Visual Studio that are not included out of the box? I'd like to be able to: Add projects and references by dragging to the Solution Explorer. Collapse to project definitions in the Solution Explorer. Although the second can be achieved with a macro. PS: R# is does not count as a feature!

  • Jquery toggle functions

    - by ozsenegal
    I've a code to sort table using Jquery.I use toggle function to alternate clicks,and toggle beetween 'ascend' and 'descend' sort.Once you click header's table it should sort it contents. However,there's a bug: I click once,it sorts,then when i click again,nothing happens.I need to click again (second time) to execute the second function,and sort again. Toggle should switch functions with single clicks,not double,am i right? Here is the code: firstRow.toggle(function() { $(this).find("th:first").removeClass("ascendFirst").addClass("descendFirst"); $(this).find("th:not(first)").removeClass("ascend").addClass("descend"); sorted = $.makeArray($("td:eq(0)", "tr")).sort().reverse(); sorted2 = $.makeArray($("td:eq(1)", "tr")).sort().reverse(); sorted3 = $.makeArray($("td:eq(2)", "tr")).sort().reverse(); for (var i = 0; i < sorted.length; i++) { $("td", "tr:eq(" + (i + 1) + ")").remove(); $("tr:eq(" + (i + 1) + ")").append($("<td></td>").text($(sorted[i]).text())); $("tr:eq(" + (i + 1) + ")").append($("<td></td>").text($(sorted2[i]).text())); $("tr:eq(" + (i + 1) + ")").append($("<td></td>").text($(sorted3[i]).text())); } }, function() { $(this).find("th:first").removeClass("descendFirst").addClass("ascendFirst"); $(this).find("th:not(first)").removeClass("descend").addClass("ascend"); sorted = $.makeArray($("td:eq(0)", "tr")).sort(); sorted2 = $.makeArray($("td:eq(1)", "tr")).sort(); sorted3 = $.makeArray($("td:eq(2)", "tr")).sort(); for (var i = 0; i < sorted.length; i++) { $("td", "tr:eq(" + (i + 1) + ")").remove(); $("tr:eq(" + (i + 1) + ")").append($("<td></td>").text($(sorted[i]).text())); $("tr:eq(" + (i + 1) + ")").append($("<td></td>").text($(sorted2[i]).text())); $("tr:eq(" + (i + 1) + ")").append($("<td></td>").text($(sorted3[i]).text())); } });
