• Eclipse plugin to measure programmer performance/stats

  - by trenki

  Does anyone know of an Eclipse plugin that can give me some stats about my behavior/usage of the Eclipse IDE? There are quite a few things I would like to know: How often/when do I invoke the "Build All" command (through Ctrl+B) How often does compilation fail/succeed (+ number of errors/warnings) How often do I hit Backspace? (I do that way to often; If pressing that key would give a nasty sound I would in time learn to type correctly in the first place) How many characters/lines of code that I typed do I delete (possibly quite immediately) How (effective/efficient/...) is my Mouse/Keyboard/IDE usage? (Kinda like measuring APM in StarCraft; this could be fun) If there is no such Eclipse plugin around, how complex and time consuming would It be to write a plugin that can accomplish the above?

• MySQL column names and aliases

  - by user329820

  hi, I have read that after select we use column-names but I have found a statement that was like this: SELECT 'A' FROM T WHERE A = NULL; would you lease help me? thanks (A is a column- name here?) my DBMS is MySQL EDITED : the exact question is this that: Will the above statement produce a row (select all that apply)? Notice that ANSI_NULLS is OFF. I want to know that the above statement will work? because some of you said that we should write IS NULL instead of =null

• Elegant way to distinct Path or Entry key

  - by sum1stolemyname

  I have an application loading CAD data (Custom format), either from the local filesystem specifing an absolute path to a drawing or from a database. Database access is realized through a library function taking the drawings identifier as a parameter. the identifiers have a format like ABC 01234T56-T, while my paths a typical windows Paths (eg x:\Data\cadfiles\cadfile001.bin). I would like to write a wrapper function Taking a String as an argument which can be either a path or an identifier which calls the appropriate functions to load my data. Like this: Function CadLoader(nameOrPath : String):TCadData; My Question: How can I elegantly decide wether my string is an idnetifier or a Path to a file? Use A regexp? Or just search for '\' and ':', which are not appearing in the Identifiers?

• How do I unpack bits from a structure's stream_data in c code?

  - by Chelp

  Ex. typedef struct { bool streamValid; dword dateTime; dword timeStamp; stream_data[800]; } RadioDataA; Ex. Where stream_data[800] contains: **Variable** **Length (in bits)** packetID 8 packetL 8 versionMajor 4 versionMinor 4 radioID 8 etc.. I need to write: void unpackData(radioDataA *streamData, MA_DataA *maData) { //unpack streamData (from above) & put some of the data into maData //How do I read in bits of data? I know it's by groups of 8 but I don't understand how. //MAData is also a struct. }

• Django: IE doesn't load locahost or loads very SLOWLY

  - by reedvoid

  I'm just starting to learn Django, building a project on my computer, running Windows 7 64-bit, Python 2.7, Django 1.3. Basically whatever I write, it loads in Chrome and Firefox instantly. But for IE (version 9), it just stalls there, and does nothing. I can load up "http://127.0.0.1:8000" on IE and leave the computer on for hours and it doesn't load. Sometimes, when I refresh a couple of times or restart IE it'll work. If I change something in the code, again, Chrome and Firefox reflects changes instantly, whereas IE doesn't - if it loads the page at all. What is going on? I'm losing my mind here....

• hook to save action in eclipse plugin

  - by 4485670

  I want to create a Google Closure Compiler plugin for eclipse. I already have a popup menu entry to compile a Javascript file to its minified version. But it would be more than helpful if every time you save a *.js that minified version would be generated automatically. I read/heard about natures and builders, extension points and IResourceChangeListener. But I did not manage to figure out what I should use and especially how to get it to work. Is there a working example of a plugin that does "the same kind of thing" so I can work from that or a tutorial to write such? With the answer below I searched for projects that use the IResourceChangeListener and came up with this code: manifest: http://codepaste.net/3yahwe plugin.xml: http://codepaste.net/qek3rw activator: http://codepaste.net/s7xowm DummyStartup: http://codepaste.net/rkub82 MinifiedJavascriptUpdater: http://codepaste.net/koweuh There in the MinifiedJavascriptUpdater.java which holds the code for the IResourceChangeListener the "resourceChanged" function is never reached.

• Passing an array of structures to an Oracle stored procedure (CFMX)

  - by Patti

  I'm looking to write a Oracle stored procedure where I would pass in (from ColdFusion) an array of structures and loop over each iteration to insert the bits and pieces within the structures to the DB., I haven't written this type of procedure / package before. I am planning to do an sp / package similar to what is sketched out in the second reply to this thread: How to pass a array of object to oracle stored procedure Assuming I do, how can I call the procedure from ColdFusion (I'm using MX) and pass in my array? As far as I can see, none of the CF_SQL_Types make sense.

• detect a string contained by another discontinuously

  - by SpawnCxy

  Recently I'm working on bad content(such as advertise post) filter of a BBS.And I write a function to detect a string is in another string not continuously.Code as below: $str = 'helloguys'; $substr1 = 'hlu'; $substr2 = 'elf'; function detect($a,$b) //function that detect a in b { $c = ''; for($i=0;$i<=strlen($a);$i++) { for($j=0;$j<=strlen($b);$j++) { if($a[$i] == $b[$j]) { $b=substr($b,$j+1); $c .=$a[$i]; break; } } } if($c == $a) return true; else return false; } var_dump(detect($substr1,$str)); //true var_dump(detect($substr2,$str)); //false Since the filter works before the users do their posts so I think the efficiency here is important.And I wonder if there's any better solution? Thanks!

• Compare images to find differences

  - by _simon_

  Task: I have a camera mounted on the end of our assembly line, which captures images of produced items. Let's for example say, that we produce tickets (with some text and pictures on them). So every produced ticket is photographed and saved to disk as image. Now I would like to check these saved images for anomalies (i.e. compare them to an image (a template), which is OK). So if there is a problem with a ticket on our assembly line (missing picture, a stain,...), my application should find it (because its image differs too much from my template). Question: What is the easiest way to compare pictures and find differences between them? Do I need to write my own methods, or can I use existing ones? It would be great if I just set a tolerance value (i.e. images can differ for 1%), put both images in a function and get a return value of true or false :) Tools: C# or VB.NET, Emgu.CV (.NET wrapper for OpenCV) or something similar

• Creating AVI files in OpenCV

  - by user80003

  Hello. I have been trying to create an application using OpenCV and Visual Studio 2008, to capture images from a webcam, apply a filter to them, and then write them to an AVI file. Everything works, except creating the AVI file. The problem is that it works on my computer, but it doesn't work on my colleague's computer. The reason for that (I think) is that he does not have the necessary video encoders for OpenCV to use. The cvCreateVideoWriter function does not return NULL, but I end up with a 0kb file on the disk.

• NUnit [Test] is not a valid attribute

  - by tyndall

  I've included the necessary assemblies into a Windows Class project in VS2008. When I start to try to write a test I get a red squiggle line and the message [Test] is not a valid attribute. I've used NUnit before... maybe an earlier version. What am I doing wrong? I'm on version 2.5.2. using System; using System.Collections.Generic; using System.Linq; using System.Text; using NUnit; using NUnit.Core; using NUnit.Framework; namespace AccessPoint.Web.Test { public class LoginTests { [Test] public void CanLogin() { } } }

• PHP, MySQL - can you distinguish between rows matched and rows affected?

  - by Renesis

  I am trying to write a PHP-MySQL database processor that is somewhat intelligent. When this processor decides it needs to make an update, I want to report if it was really successful or not. I thought I could use mysql_affected_rows... // Example: // After running query "UPDATE mytable SET name='Test' WHERE ID=1" $result = mysql_affected_rows(); if ($result >= 1) { /* Success */ } If, for example, there was no row with ID=1, then $result would be 0. However, it turns out that PHP's mysql_affected_rows is the actual affected rows, and may be still be 0 if the row exists but name was already "Test". (The PHP docs even say this is the case). If I run this in the command line, I get the following meta information about the query: Query OK, 0 rows affected (0.01 sec) Rows matched: 1 Changed: 0 Warnings: 0 Is there any way for me to get that "Rows matched" value in PHP instead of the affected rows?

• Starting a new Xcode project from a template vs. a blank project

  - by Dr Dork

  I sometimes find it's easier to create a new project from scratch in other IDEs simply because its often more difficult to understand and tweak the generated template code than it is to write the code you need from scratch. Do seasoned iPhone developers still use templates when creating new projects? How difficult is it to add functionality to a template project that isn't initially included in the template? For example, if I don't check the "Use Core Data" option when creating a new project, how difficult does that make it to use Core Data later on if I changed my mind?

• Ignore document style rules in one element.

  - by panzi

  I write a greasemonkey script that adds sticky notes to websites. Because there sometimes are pretty strange style rules used in some websites the sticky notes sometimes turn up messed up (or at least not looking like I want them to look). Is there a way to say "under this element do not apply any generic stylerules"? So that rules associated with tag names are not applied, but rules associated with certain classes and ids still are. Or does anyone have a better idea on how to ensure that only my styles are applied to the sticky notes?

• concurrent doubly-linked list (1 writer, n-readers)

  - by Arne

  Hi guys, I am back in the field of programming for my Diploma-thesis now and stumbled over the following issue: I need to implement a thread-safe doubly-linked list for one thread writing the list at any position (delete, insert, mutate node data) and one to many threads traversing and reading the list. I am well aware that mutexes can be used to serialize access to the list, still I presume that a naive lock around any write operation will be less than optimal. I am wondering whether there are better variants. (I am well aware that 'optimal' has not much of a practical meaning as long as no exact measure/profiling are available but this is an academic thesis after all..) I am very gratefull for code-samples as well as references to academic granted these have at least a tiny bit of practical relevance. Thanks at lot

• Load custom class properly

  - by LinusAn

  I have a custom class which I want to "load" inside the firstViewController and then access it from other classes by segues. My Problem is, I can't even access and change the instance variable inside the firstViewController. Somehow I'm "loading" it wrong. Here is the code I used until now: inside viewController.h @property (strong, nonatomic) myClass *newClass; inside viewController.m @synthesize newClass; I then try to access it by: self.newClass.string = @"myString"; if(newClass.string == @"myString"){ NSLog(@"didn't work"); } Well, I get "didn't work". Why is that? When I write myClass *newClass = [myClass new]; It does work. But the class and its properties gets overwritten every time the ViewController loads again. What would you recommend? Thank you very much.

• Ignoring specific differences in diff

  - by naumcho

  When doing recursive diffs I want to ignore expected differences/translations - is there a way to do that with standard unix tools? E.g. file1: 1 ... 2 /path/to/something/ver1/blah/blah 3 /path/to/something/ver1/blah/blah 4 ... file2: 1 ... 2 /path/to/something/ver2/blah/blah 3 /path/to/something/ver3/blah/blah 4 ... I want to be able to do something like: diff file1 file2 --ignore-transltion "ver1>ver2" This should show only show me that line 3 is different Does anyone know of a good way to do that? I can easily write a perl script to do it but i will end up re-implementing most of the rest of the functionality of 'diff'. Update: My goal is to run this on directories with different versions of the same files with "diff -r" so I can spot unexpected differences in versions.

• C++ Arrays of Structure access

  - by learningtolive

  Hi, I'm studying C++ from Schildt's book and don't quite understand what does he mean under third structure; Can somebody explain this - To access a specific structure within an array of structures, you must index the structure name. For example, to display the on_hand member of the third structure, you would write cout cout << invtry[2].on_hand; Some code: struct type{ char item[40]; double cost; double retail; int on_hand; int lead_time; }invtry[SIZE];

• Is there a jQuery plugin for making a step-by-step type presentation?

  - by Earlz

  Hello, I was making a small thing in HTML and basically I have some "frames" like <div id="frame_1"> ... </div> <div id="frame_2"> ... </div> ... Basically what I want is for only one frame to be visible at one time and to navigate between frames easily with previous and next buttons (navigation by frame number a plus, but not required) Before I set out to write it myself I figured someone had already done it so has it been done?

• How do I turn a PDF email attachment to an image (jpg) in a PHP page?

  - by user351630

  Hi guys. Long time viewer, first time question asker. I'm trying to have my personal website parse through my mail box for attachments from a certain subscription list, and then be able to view the PDF attachments as images, preferably jpg. With the help of this: http://www.linuxscope.net/articles/mailAttachmentsPHP.html I'm currently using imap_base64() to decode the MIME data and create the PDF. However, I hate using PDF readers in general and I thought it would be a lot more streamlined if I could just view it as an image instead. I've heard for convert with ImageMagick, but would I need to actually write the PDF to a directory before using this, or can I convert somehow directly from the MIME data in the email? Thanks in advanced!

• jQuery AJAX & an ASP.NET web service works locally but not remotely

  - by Alex

  Interesting one here. I have an ASP.NET 1.1 project that contains a web service in it. I'm using jQuery's AJAX functionality to call some services from the client. This is what my code looks like: $.ajax({ type: "POST", url: 'foo.asmx/functionName', data: 'foo1=' + foo1 + '&foo2=' + foo2, dataType: "xml", success: function(xml) { //do something with my xml data }, error: function(request, error){ //handle my error } }); This works great when I run the site from my IDE on localhost. However, when I deploy this site to any other server I get a parsererror error from jQuery. It does not appear to even call my service as I dropped in some code to write a log file to disk and it's not making it there. The same exact XML should be returned from both my localhost and the server I deployed to. Any ideas?

• Java generics: actual class as a generic parameter.

  - by user554916

  What do I write instead of "TheClass" to make this work? Or is there an alternative way to do it (possibly without making WithName and WithAge generic)? class Item { NeigborList<TheClass> neighbors; } class WithName extends Item { // here I want neighbors to be a NeighborList<WithName> String name; void someMethod() { System.out.println(neighbors.nearestTo(this).name); } } class WithAge extends Item { // here I want neighbors to be a NeighborList<WithAge> int age; void someOtherMethod() { System.out.println(neighbors.nearestTo(this).age); } }

• Set argument pointer to point to new memory inside a function (without returning it) IN C

  - by user321605

  Hello, Hopefully my title was descriptive enough to attract the right help. I want to write a function that will return 1 thing, and modify a provided pointer in another. My current function declaration is . . . char * afterURL replaceURLS(char * body) What I want to do is copy all of body's data into a new string, and set body to point to this new data. I then want afterURL to point to a location within the new string. My issue is getting the actual pointer that is passed in to this function to point to the new data. Thanks in advance! Rob
