  • Old fashioned html onclick return false doesnt in IE work when jquery script included

    - by user292662
    Ok, so im quite new to jquery but found this bizzar problem just now, If we ignore jquery for a second and consider this scenario, if i have two links like below both with an href and both with and onclick event. The first link will not follow the href because the onclick returns false, and the second link will because the onclick returns true. <a href="/page.html" onclick="return false;">Dont follow</a> <a href="/page.html" onclick="return false;">Follow</a> This works just hunky dory in every browser as it should, the thing is, as soon as i include the jQuery script on the page this stops working in all versions of IE which then always follows the href whether the onclick returns false or not. (it continues to work fine in other browsers) Now if i add an event using jquery and call .preventDefault() on the event object instead of doing it the old fashioned way this behaves correctly, and you may say, well just do that then? But i have a site with thousands of lines of code and i am adding jquery support, i dont want to run the risk that i might miss an already defined html onclick="" and break the website. I cant see why jQuery should prevent perfectly normal javascript concepts from working, so is this a jQuery bug or am I missing something?

  • Latex multicols. Can I group content so it won't split over cols and/or suggest colbreaks?

    - by valadil
    Hi. I'm trying to learn LaTeX. I've been googling this one for a couple days, but I don't speak enough LaTeX to be able to search for it effectively and what documentation I have found is either too simple or goes way over my head (http://www.uoregon.edu/~dspivak/files/multicol.pdf) I have a document using the multicol package. (I'm actually using multicols* so that the first col fills before the second begins instead of trying to balance them, but I don't think that's relevant here.) The columns output nicely, but I want to be able to indicate that some content won't be broken up into different columns. For instance, aaaaaaaa bbbbbbb aaaaaaaa bbbbbbb aaaaaaaa ccccccc bbbbbbbb ccccccc That poor attempt at ascii art columns is what's happening. I'd like to indicate that the b block is a whole unit that shouldn't be broken up into different columns. Since it doesn't fit under the a block, the entirety of the b block should be moved to the second column. Should b be wrapped in something? Is there a block/float/section/box/minipage/paragraph structure I can use? Something specific to multicol? Alternatively is there a way that I can suggest a columnbreak? I'm thinking of something like \- that suggests a hyphenated line break if its convenient, but this would go between blocks. Thanks!

  • Extremely strange glitch in Chrome - parses contents of string!

    - by George Edison
    Okay - this is the dumbest glitch I have seen in a while: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <script type='text/javascript'> var data = "</script>"; </script> </head> <body> This should break! </body> </html> This causes syntax errors because the JavaScript parser is actually reading the contents of the string. How stupid! How can I put </script> in my code. Is there any way? Is there a valid reason for this behavior?

  • Use .bat file to recursively loop through folders and get hold of .class files

    - by user320550
    HI all, This is what i'm trying to do. I have a .bat file which takes in a argument which is nothing but a folder name. What i do first is go one level up (cd ..). Now in this directory i have 3 folders and each folders have sub-folders and have .class files in them. What i want to do is recursively loop through the folders and get hold of the .class files. Once this is done i want to echo the target folder of the .class file as well as echo the name of the.class file. So c:\temp\potter\myclass.class. I would echo out c:\temp\potter\ and myclass. I'm able to do this by writing a separate bat file which works. But when i integrate this with the recursive function it seems to break. This is what i'm doing: :: call the junit classes... and save the results echo step 3... cd %1 cd .. for /r %%a in (*.class) do set Var=%%a echo Full file location %Var% for %%i in ("%Var%") do Set CF=%%~dpi Set CF=%CF:~0,-1% :LOOP If "%CF:~-1,1%"=="\" GoTo :DONE Set CF=%CF:~0,-1% GoTo :LOOP :DONE Set CF=%CF:~0,-1% echo Folder Location %CF% ::cd %CF% For %%j in ("%Var%") Do Set name=%%~nxj :: -6 because of Quotations Set name=%name:~0,-6% echo File Name %name% echo step 3 complete... However i only get the output of one directory, while i have multiple directories having .class files. This is the output i get: step 3... Full file location C:\NKCV\Project\MyActivities\6_Selenium\htmlTestCasesConve rted2JUnit\iexplore\flow2\testCase_app2.class Folder Location C:\NKCV\Project\MyActivities\6_Selenium\htmlTestCasesConverte d2JUnit\iexplore\flow2 File Name testCase_app2 step 3 complete... missing argument! usage htmltestCaseLocation for eg., "C:\NKCV\Project\MyActivities\6_Selenium\htmlTestCases" Could anyone please let me know whats wrong here? Thanks.

  • Autoselect, focus and highlight a new NSOutlineView row

    - by coneybeare
    This is probably just lack of experience with the NSOutlineView but I can't see a way to do this. I have a NSOutlineView (implemented with the excellent PXSourceList) with an add button that is totally functional in the aspect that I save/write/insert/delete rows correctly. I do not use a NSTreeController, and I don't use bindings. I add the entity using the following code: - (void)addEntity:(NSNotification *)notification { // Create the core data representation, and add it as a child to the parent node UABaseNode *node = [[UAModelController defaultModelController] createBaseNode]; [sourceList reloadData]; for (int i = 0; i < [sourceList numberOfRows]; i++) { if (node == [sourceList itemAtRow:i]) { [sourceList selectRowIndexes:[NSIndexSet indexSetWithIndex:i] byExtendingSelection:NO]; [sourceList editColumn:0 row:i withEvent:nil select:NO]; break; } } } When the add button is pressed, a new row is inserted like this: If I click away, then select the row and press enter to edit it, it now looks like this: My question is: How can I programmatically get the same state (focus, selected, highlighted) the first time, to make the user experience better?

  • Objective C Enumerate Sentences in a paragraph

    - by Faz Ya
    I would like to write an enumerator that would go through a paragraph of text and gives me one sentence at a time. I tried using stringEnumerate with the NSStringEnumerationBySentences but that simply looks at the periods and fails. For example, lets say I have the following text Block: "Senator John A. Boehner decided not to move forward. He also decided not to call the congress. The news reporter said though...." I would like my function to break down the above paragraph in the following sentences: Senator John A. Boehner decided not to move forward He also decided not to call the congress (No third sentence because it's a half a sentence) The String Enumerator with the sentence optionjust looks at the periods and breaks down that way which is wrong: Senator John A. Boehner decided not to move forward He also decided not to call the congress The news reporter said though.... Is there any library or function that I can call that does a better job at this? Thanks - (NSMutableString *) getOnlyFullSentencesFromTextBlock:(NSMutableString *) textBlock{ [textBlock enumerateSubstringsInRange:NSMakeRange(0, [textBlock length]) options:NSStringEnumerationBySentences | NSStringEnumerationLocalized usingBlock:^(NSString *substring, NSRange substringRange, NSRange enclosingRange, BOOL *stop) { NSLog(@"Sentence Frag:%@", substring); }]; return textBlock; }

  • Regular expression for dividing country calling codes

    - by RickiG
    Hi I have a list of calling codes for all countries(the phone number prefixes), I would like to split them up in the country name and the actual code so I can put then into an xml. I have tried back and forth but can not get a regexp going that takes all cases into account. I think it is fairly simple for someone with a bit of experience. The codes have these formats: Afghanistan 93 Anguilla 1 264 Antarctica 6721 Antigua and Barbuda 1 268 Bosnia and Herzegovina 387 Canada 1 Congo, Republic of the 242 Cote d'Ivoire 225 Ireland (Eire) 353 United States of America 1 There are around 235 of them in total, but these are the regulars and the exceptions. ^[a-zA-Z]\s,'()] for between 1 and X words and then it is [0-9\s]{1,5}$ for the numbers: X XX XXX XXXX X XXX So if I should express it as a sentence it would be: "from beginning of a line, take all characters (1) including space,'() until you encounter digits, then take all of these including space(2) until you encounter a line break." I am using TextMate, and the docs says: TextMate uses the Oniguruma regular expression library by K. Kosako. I would appreciate any help given:) Thank you.

  • jQuery & Prototype Conflict

    - by DPereyra
    Hi, I am using the jQuery AutoComplete plugin in an html page where I also have an accordion menu which uses prototype. They both work perfectly separately but when I tried to implement both components in a single page I get an error that I have not been able to understand. uncaught exception: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIDOMViewCSS.getComputedStyle]" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: file:///C:/Documents and Settings/Administrator/Desktop/website/js/jquery-1.2.6.pack.js :: anonymous :: line 11" data: no] I found out the file conflicting with jQuery is 'effects.js' which is used by the accordion menu. I tried replacing this file with a newer version but newer seems to break the accordion behavior. My guess is that the 'effects.js' file used in the accordion was modified to obtain the accordion demo output. I also tried using the overriding methods jQuery needs to avoid conflict with other libraries and that did not work. I obtained the accordion demo from the following site: http://www.stickmanlabs.com/accordion/ And the jQuery AutoComplete can be obtained from: http://docs.jquery.com/Plugins/Autocomplete#Setup Has any one else experienced this issue? Thanks.

  • Query next/previous record

    - by Rob
    I'm trying to find a better way to get the next or previous record from a table. Let's say I have a blog or news table: CREATE TABLE news ( news_id INT UNSIGNED NOT NULL PRIMARY KEY AUTO_INCREMENT, news_datestamp DATETIME NOT NULL, news_author VARCHAR(100) NOT NULL, news_title VARCHAR(100) NOT NULL, news_text MEDIUMTEXT NOT NULL ); Now on the frontend I want navigation buttons for the next or previous records, if i'm sorting by news_id, I can do something rather simple like: SELECT MIN(news_id) AS next_news_id FROM news WHERE news_id > '$old_news_id' LIMIT 1 SELECT MAX(news_id) AS prev_news_id FROM news WHERE news_id < '$old_news_id' LIMIT 1 But the news can be sorted by any field, and I don't necessarily know which field is sorted on, so this won't work if the user sorts on news_author for example. I've resorted to the rather ugly and inefficient method of sorting the entire table and looping through all records until I find the record I need. $res = mysql_query("SELECT news_id FROM news ORDER BY `$sort_column` $sort_way"); $found = $prev = $next = 0; while(list($id) = mysql_fetch_row($res)) { if($found) { $next = $id; break; } if($id == $old_news_id) { $found = true; continue; } $prev = $id; } There's got to be a better way.

  • Recursion in prepared statements

    - by Rob
    I've been using PDO and preparing all my statements primarily for security reasons. However, I have a part of my code that does execute the same statement many times with different parameters, and I thought this would be where the prepared statements really shine. But they actually break the code... The basic logic of the code is this. function someFunction($something) { global $pdo; $array = array(); static $handle = null; if (!$handle) { $handle = $pdo->prepare("A STATEMENT WITH :a_param"); } $handle->bindValue(":a_param", $something); if ($handle->execute()) { while ($row = $handle->fetch()) { $array[] = someFunction($row['blah']); } } return $array; } It looked fine to me, but it was missing out a lot of rows. Eventually I realised that the statement handle was being changed (executed with different param), which means the call to fetch in the while loop will only ever work once, then the function calls itself again, and the result set is changed. So I am wondering what's the best way of using PDO prepared statements in a recursive way. One way could be to use fetchAll(), but it says in the manual that has a substantial overhead. The whole point of this is to make it more efficient. The other thing I could do is not reuse a static handle, and instead make a new one every time. I believe that since the query string is the same, internally the MySQL driver will be using a prepared statement anyway, so there is just the small overhead of creating a new handle on each recursive call. Personally I think that defeats the point. Or is there some way of rewriting this?

  • pthread_exit and/or pthread_join causing Abort and SegFaults.

    - by MJewkes
    The following code is a simple thread game, that switches between threads causing the timer to decrease. It works fine for 3 threads, causes and Abort(core dumped) for 4 threads, and causes a seg fault for 5 or more threads.

  • Using bash to copy file to spec folders

    - by Franko
    I have a folder with a fair amount of subfolders. In some of the subfolders do I have a folder.jpg picture. What I try to do find that folder(s) and copy it to all other subfolders that got the same artist and album information then continue on to the next album etc. The structure of all the folders are "artist - year - album - [encoding information]". I have made a really simple one liner that find the folders that got the file but there am I stuck. ls -F | grep / | while read folders;do find "$folders" -name folder.jpg; done Anyone have any good tip or ideas how to solve this or pointers how to proceed? Edit: First of all, i´m real new to this (like you cant tell) so please have patience. Ok, let me break it down even more. I have a folder structure that looks like this: artist1 - year - album - [flac] artist1 - year - album - [mp3] artist1 - year - album - [AAC] artist2 - year - album - [flac] etc I like to loop over the set of folders that have the same artist and album information and look for a folder.jpg file. When I find that file do I like to copy it to all of the other folders in the same set. Ex if I find one folder.jpg in artist1 - year - album - [flac] folder do I like to have that folder.jpg copied to artist1 - year - album - [mp3] & artist1 - year - album - [AAC] but not to artist2 - year - album - [flac]. The continue the loop until all the sets been processed. I really hope that makes it a bit more easy to understand what I try to do :)

  • C ] How can I handle weird errors from calculating acos / sin / atan2?

    - by Phrixus
    Has anyone seen this weird value while handling sin / cos/ tan / acos.. math stuff? ===THE WEIRD VALUE=== -1.#IND00 ===================== void inverse_pos(double x, double y, double& theta_one, double& theta_two) { // Assume that L1 = 350 and L2 = 250 double B = sqrt(x*x + y*y); double angle_beta = atan2(y, x); double angle_alpha = acos((L2*L2 - B*B - L1*L1) / (-2*B*L1)); theta_one = angle_beta + angle_alpha; theta_two = atan2((y-L1*sin(theta_one)), (x-L1*cos(theta_one))); } This is the code I was working on. In a particular condition - like when x & y are 10 & 10, this code stores -1.#IND00 into theta_one & theta_two. It doesn't look like either characters or numbers :( Without a doubt, atan2 / acos / stuff are the problems. But the problem is, try and catch doesn't work either cuz those double variables have successfully stored some values in them. Moreover, the following calculations never complain about it and never break the program! I'm thinking of forcing to use this value somehow and make the entire program crash... So that I can catch this error.. Except for that idea, I have no idea how I should check whether these theta_one and theta_two variables have stored this crazy values. Any good ideas? Thank you in advance..

  • Finding Local IP via Socket Creation / getsockname

    - by BSchlinker
    I need to get the IP address of a system within C++. I followed the logic and advice of another comment on here and created a socket and then utilized getsockname to determine the IP address which the socket is bound to. However, this doesn't appear to work (code below). I'm receiving an invalid IP address (58.etc) when I should be receiving a 128.etc Any ideas? string Routes::systemIP(){ // basic setup int sockfd; char str[INET_ADDRSTRLEN]; sockaddr* sa; socklen_t* sl; struct addrinfo hints, *servinfo, *p; int rv; memset(&hints, 0, sizeof hints); hints.ai_family = AF_UNSPEC; hints.ai_socktype = SOCK_DGRAM; if ((rv = getaddrinfo("4.2.2.1", "80", &hints, &servinfo)) != 0) { fprintf(stderr, "getaddrinfo: %s\n", gai_strerror(rv)); return "1"; } // loop through all the results and make a socket for(p = servinfo; p != NULL; p = p->ai_next) { if ((sockfd = socket(p->ai_family, p->ai_socktype, p->ai_protocol)) == -1) { perror("talker: socket"); continue; } break; } if (p == NULL) { fprintf(stderr, "talker: failed to bind socket\n"); return "2"; } // get information on the local IP from the socket we created getsockname(sockfd, sa, sl); // convert the sockaddr to a sockaddr_in via casting struct sockaddr_in *sa_ipv4 = (struct sockaddr_in *)sa; // get the IP from the sockaddr_in and print it inet_ntop(AF_INET, &(sa_ipv4->sin_addr.s_addr), str, INET_ADDRSTRLEN); printf("%s\n", str); // return the IP return str; }

  • Designing small comparable objects

    - by Thomas Ahle
    Intro Consider you have a list of key/value pairs: (0,a) (1,b) (2,c) You have a function, that inserts a new value between two current pairs, and you need to give it a key that keeps the order: (0,a) (0.5,z) (1,b) (2,c) Here the new key was chosen as the average between the average of keys of the bounding pairs. The problem is, that you list may have milions of inserts. If these inserts are all put close to each other, you may end up with keys such to 2^(-1000000), which are not easily storagable in any standard nor special number class. The problem How can you design a system for generating keys that: Gives the correct result (larger/smaller than) when compared to all the rest of the keys. Takes up only O(logn) memory (where n is the number of items in the list). My tries First I tried different number classes. Like fractions and even polynomium, but I could always find examples where the key size would grow linear with the number of inserts. Then I thought about saving pointers to a number of other keys, and saving the lower/greater than relationship, but that would always require at least O(sqrt) memory and time for comparison. Extra info: Ideally the algorithm shouldn't break when pairs are deleted from the list.

  • How to check if two records have a self-referencing relation?

    - by Machine
    Consider the following schema with users and their collegues (friends): Users User: columns: user_id: name: user_id as userId type: integer(8) unsigned: 1 primary: true autoincrement: true first_name: name: first_name as firstName type: string(45) notnull: true last_name: name: last_name as lastName type: string(45) notnull: true email: type: string(45) notnull: true unique: true relations: Collegues: class: User local: invitor foreign: invitee refClass: CollegueStatus equal: true onDelete: CASCADE onUpdate: CASCADE Join table: CollegueStatus: columns: invitor: type: integer(8) unsigned: 1 primary: true invitee: type: integer(8) unsigned: 1 primary: true status: type: enum(8) values: [pending, accepted, denied] default: pending notnull: true Now, let's say I two records, one for the user making a HTTP request (the logged in user), and one record for a user he wants to send a message to. I want to check if these users are collegues. Questions: Does Doctrine have any pre-build functionality to check if two records with with self-relations are related? If not, how would you write a method to check this? Where would you put said method? (In the User-class, UserTable-class etc) I could probably do something like this: public function (User $user1, User $user2) { // Ensure we load collegues if $user1 was fetched with DQL that // doesn't load this relation $collegues = $user1->get('Collegues'); $areCollegues = false; foreach($collegues as $collegue) { if($collegue['userId'] === $user2['userId']) { $areCollegues = true; break; } } return $areCollegues; } But this looks a neither efficient nor pretty. I just feel that it should be solved already for self-referencing relations to be nice to use.

  • confused about how to use JSON in C#

    - by Josh
    The answer to just about every single question about using C# with json seems to be "use JSON.NET" but that's not the answer I'm looking for. the reason I say that is, from everything I've been able to read in the documentation, JSON.NET is basically just a better performing version of the DataContractSerializer built into the .net framework... Which means if I want to deserialize a JSON string, I have to define the full, strongly-typed class for EVERY request I might have. so if I have a need to get categories, posts, authors, tags, etc, I have to define a new class for every one of these things. This is fine if I built the client and know exactly what the fields are, but I'm using someone else's api, so I have no idea what the contract is unless I download a sample response string and create the class manually from the JSON string. Is that the only way it's done? Is there not a way to have it create a kind of hashtable that can be read with json["propertyname"]? Finally, if I do have to build the classes myself, what happens when the API changes and they don't tell me (as twitter seems to be notorious for doing)? I'm guessing my entire project will break until I go in and update the object properties... So what exactly is the general workflow when working with JSON? And by general I mean library-agnostic. I want to know how it's done in general, not specifically to a target library... I hope that made sense, this has been a very confusing area to get into... thanks!

  • Newb Question: scanf() in C

    - by riemannliness
    So I started learning C today, and as an exercise i was told to write a program that asks the user for numbers until they type a 0, then adds the even ones and the odd ones together. Here is is (don't laugh at my bad style): #include <stdio.h>; int main() { int esum = 0, osum = 0; int n, mod; puts("Please enter some numbers, 0 to terminate:"); scanf("%d", &n); while (n != 0) { mod = n % 2; switch(mod) { case 0: esum += n; break; case 1: osum += n; } scanf("%d", &n); } printf("The sum of evens:%d,\t The sum of odds:%d", esum, osum); return 0; } My question concerns the mechanics of the scanf() function. It seems that when you enter several numbers at once separated by spaces (eg. 1 22 34 2 8), the scanf() function somehow remembers each distinct numbers in the line, and steps through the while loop for each one respectively. Why/how does this happen? Example interaction within command prompt: - Please enter some numbers, 0 to terminate: 42 8 77 23 11 (enter) 0 (enter) - The sum of evens:50, The sum of odds:111 I'm running the program through the command prompt, it's compiled for win32 platforms with visual studio.

  • How can you make a PHP application require a key to work?

    - by jasondavis
    About 4 years ago I used a php product called amember pro, it is a membership script which has plugins for lie 30 different payment processors, it was an easy way to set up an automated membership site where users would pay a payment and get access to a certain area. The script used ioncube http://www.ioncube.com/sa_encoder.php to prevent non-paying users from using the script, it requered that you register the domain that the script would be used on, you were then given a key to enter into the file that would make the system/script work. Now I am wanting to know how to do such a task, I know ioncube encoder just makes it hard to see the code, in the script I mention, they would just have a small section at the tp of 1 of the included pages that was encrypted and without that part of the code it would break and in addition if the owner of the script did not put you domain in the list and give you a valid key it would not work, also if you tried to use the script on a different domain it would not work. I realize that somewhere in the encrypted code that is must of sent you key to there server and checked that it was valid for the domain name it is on, or possibly it did not even do that, maybe the key would just verify that it matched the domain the script was on, that more likely what it did. Here is where the real question is, How would you make a script require the portion that is encrypted? If I made a script and had a small encrypted part at the top, it would seem a user would be able to easily just remove the encrypted part and figure out what the non encrypted part is doing and fix it to work. Any ideas?

  • "One or more breakpoints cannot be set and have been disabled. Execution will stop at the beginning

    - by sam
    I set a breakpoint in my code in Visual-C++, but when I run, I see the error mentioned in the title. I know this question has been asked before on Stack Overflow (http://stackoverflow.com/questions/657470/breakpoints-cannot-be-set-and-have-been-disabled-problem), but none of the answers there fully explained the problem I'm seeing. The closest I can see is something about the linker, but I don't understand that - so if someone could explain in more detail that would be great. In my case, I have 2 projects in Visual C++ - the production dsw, and the test code dsw. I have loaded and rebuilt both dsws in debug mode. I want a breakpoint in the production code, which is run via the test scripts. My issue is I get the error message when I run the test code, because the break point is in the production code, which isn't loaded up when the test starts. Near the beginning of the test script there is a mytest_initialize() command. I imagine this goes off and loads up the production dll. Once this line has executed, I can put the breakpoint in my production code and run until I hit it. But it's quite annoying to have to run to this line, set the breakpoint and continue every time I want to run the test. So I think the problem is Visual C++ doesn't realise the two projects are related. Is this a linker issue? What does the linker do and what settings should I change to make this work? Thanks in advance. Apologies if instead I should be appending this question to the existing one, this is my first post so not quite sure how this should work.

  • MAPI find the contacts and calendar folder

    - by Rogier21
    In my outlook I have 1 exchange connection and 2 Personal Folders. I want to go fetch ALL items from the calendars and contacts so I use: /** * Create outlook application */ Outlook.Application oApp = new Outlook.Application(); Outlook.NameSpace oNS = oApp.GetNamespace("mapi"); oNS.Logon(Missing.Value, Missing.Value, true, true); /** * Loop through all the folders */ foreach (Outlook.MAPIFolder oFolder in oNS.Folders) { if (oFolder.Name == "Public Folders") { break; } /** * Get calendar items */ //Outlook.MAPIFolder oCalendar = oNS.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderCalendar); Outlook.MAPIFolder oCalendar = oFolder.Folders[5]; Outlook.Items oCalendarItems = oCalendar.Items; //Outlook.MAPIFolder oContacts = oNS.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderContacts); Outlook.MAPIFolder oContacts = oFolder.Folders[7]; Outlook.Items oContactItems = oContacts.Items; But this does not work oFolder.Folders[5] is not always 5 for the calendar, sometimes it's a different value. I cannot find the items by name oFolder.Folders["Calendar"]; because in Dutch the folder will be named "Agenda". Usually I use: Outlook.MAPIFolder oCalendar = oNS.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderCalendar); But then I only get the default calendar. How can I get the other calendars?

  • Python: Most efficient way to concatenate and rearrange files

    - by user300890
    Hi, I am reading from several files, each file is divided into 2 pieces, first a header section of a few thousand lines followed by a body of a few thousand. My problem is I need to concatenate these files into one file where all the headers are on the top followed by the body. Currently I am using two loops; one to pull out all the headers and write them, and the second to write the body of each file (I also include a tmp_count variable to limit the number of lines to be loading into memory before dumping to file). This is pretty slow - about 6min for 13gb file. Can anyone tell me how to optimize this or if there is a faster way to do this in python ? Thanks! Here is my code: def cat_files_sam(final_file_name,work_directory_master,file_count): final_file = open(final_file_name,"w") if len(file_count) > 1: file_count=sort_output_files(file_count) # only for @ headers for bowtie_file in file_count: #print bowtie_file tmp_list = [] tmp_count = 0 for line in open(os.path.join(work_directory_master,bowtie_file)): if line.startswith("@"): if tmp_count == 1000000: final_file.writelines(tmp_list) tmp_list = [] tmp_count = 0 tmp_list.append(line) tmp_count += 1 else: final_file.writelines(tmp_list) break for bowtie_file in file_count: #print bowtie_file tmp_list = [] tmp_count = 0 for line in open(os.path.join(work_directory_master,bowtie_file)): if line.startswith("@"): continue if tmp_count == 1000000: final_file.writelines(tmp_list) tmp_list = [] tmp_count = 0 tmp_list.append(line) tmp_count += 1 final_file.writelines(tmp_list) final_file.close()

  • How to overcome the programmer's block ?

    - by Nicolas Dorier
    How do you do when, during the development of your application, you can't decide yourself what to do next. You have no problem technically speaking, you have no problem to write clean code BUT you have a problem to decide yourself on what to code now. And you spend time thinking and thinking again on your design, in the car, in the shower, and you cannot write a single line of code... I think we call this "analysis paralysis". I hate being in this state ! How can you avoid this ? How do you do to not fall in this state ? I think this occurs when we are writting a big chunk of code with no visible improvement, but I'm not sure... UPDATE Like some of you said, this problem is also what we call the "programmer's block" (analogy with the writer's block). Doing some TDD doesn't help because I'm stuck, I can't decide myself what class to code, what methods to put inside (even a name of method). Though I admit that it helps to break a big chunk of code into smaller ones. Like Talesh said my head becomes full of "what-if".

  • implementing cryptographic algorithms, specifically the key expansion part

    - by masseyc
    Hey, recently I picked up a copy of Applied Cryptography by Bruce Schneier and it's been a good read. I now understand how several algorithms outlined in the book work, and I'd like to start implementing a few of them in C. One thing that many of the algorithms have in common is dividing an x-bit key, into several smaller y-bit keys. For example, blowfish's key, X, is 64-bits, but you are required to break it up into two 32-bit halves; Xl and Xr. This is where I'm getting stuck. I'm fairly decent with C, but I'm not the strongest when it comes to bitwise operators and the like. After some help on IRC, I managed to come up with these two macros: #define splitup(a, b, c) {b = a >> 32; c = a & 0xffffffff; } #define combine(a, b, c) {a = (c << 32) | a;} Where a is 64 bits and b and c are 32 bits. However, the compiler warns me about the fact that I'm shifting a 32 bit variable by 32 bits. My questions are these: what's bad about shifting a 32-bit variable 32 bits? I'm guessing it's undefined, but these macros do seem to be working. Also, would you suggest I go about this another way? As I said, I'm fairly familiar with C, but bitwise operators and the like still give me a headache.
