• Java giving incorrect year values

  - by whistler

  Something very, very strange is occurring in my program, and I'm wondering if anyone out there has seen this occur before. And, if so, how to fix it. Basically, I am parsing an csv file...no problem there. One column contains a date and I am taking it in as a String and changing to a Date object. Again, no problem there. The code is as follows: SimpleDateFormat dateFormat = new SimpleDateFormat("MM/dd/yy hh:mm"); Date initialDate = new Date(); try { initialDate = dateFormat.parse(rows.get(0)[8]); System.out.println(initialDate); } catch (ParseException e) { // TODO Auto-generated catch block e.printStackTrace(); } Of course, I'm parsing other columns as well (and those are working fine). So, when I run my program for a small csv file (2.8 MB), the dates come out (i.e. are parsed) perfectly. However, when I run the program for a large csv file (25 MB), the dates are a hot mess. For example, take a look at the year values I am getting (the following is just a tiny portion of the println output from the code above): 1000264 at Sun Nov 05 15:30:00 EST 2186 1000320 at Sat Mar 04 17:30:00 EST 2169 1000347 at Sat Apr 01 09:45:00 EDT 2169 1000413 at Tue Jul 09 13:00:00 EDT 2182 1000638 at Fri Dec 11 13:45:00 EST 2167 1000667 at Wed Dec 10 10:00:00 EST 2188 1000690 at Mon Jan 02 13:00:00 EST 2169 1000843 at Thu Feb 11 13:30:00 EST 2196 In actuality, the years are in the realm of 1990-2006 or so. Again, this does not happen with the small csv file. Does anyone know what's going on here and how I can fix it? I need to process the large csv file (the small one was just for testing purposes). By request, here are the actual dates in the csv file and after that the value given by the code above: 5/20/03 15:30 5/20/03 15:30 8/30/04 9:00 8/30/04 9:00 12/20/04 10:30 12/20/04 10:30 Sun Nov 05 15:30:00 EST 2186 Sun Nov 05 15:30:00 EST 2186 Sun Nov 05 15:30:00 EST 2186 Thu Dec 08 09:00:00 EST 2196 Tue Dec 12 10:30:00 EST 2186 Tue Dec 12 10:30:00 EST 2186

• TDD approach for complex function

  - by jamie

  I have a method in a class for which they are a few different outcomes (based upon event responses etc). But this is a single atomic function which is to used by other applications. I have broken down the main blocks of the functionality that comprise this function into different functions and successfully taken a Test Driven Development approach to the functionality of each of these elements. These elements however aren't exposed for other applications would use. And so my question is how can/should i easily approach a TDD style solution to verifying that the single method that should be called does function correctly without a lot of duplication in testing or lots of setup required for each test? I have considered / looked at moving the blocks of functionality into a different class and use Mocking to simulate the responses of the functions used but it doesn't feel right and the individual methods need to write to variables within the main class (it felt really heath robinson). The code roughly looks like this (i have removed a lot of parameters to make things clearer along with a fair bit of irrelevant code). public void MethodToTest(string parameter) { IResponse x = null; if (function1(parameter)) { if (!function2(parameter,out x)) { function3(parameter, out x); } } // ... // more bits of code here // ... if (x != null) { x.Success(); } }

• Mathematics errors in basic C++ program

  - by H Bomb1013

  I am working with a basic C++ program to determine the area and perimeter of a rectangle. My program works fine for whole numbers but falls apart when I use any number with a decimal. I get the impression that I am leaving something out, but since I'm a complete beginner, I have no idea what. Below is the source: #include <iostream> using namespace std; int main() { // Declared variables int length; // declares variable for length int width; // declares variable for width int area; // declares variable for area int perimeter; // declares variable for perimeter // Statements cout << "Enter the length and the width of the rectangle: "; // states what information to enter cin >> length >> width; // user input of length and width cout << endl; // closes the input area = length * width; // calculates area of rectangle perimeter = 2 * (length + width); //calculates perimeter of rectangle cout << "The area of the rectangle = " << area << " square units." <<endl; // displays the calculation of the area cout << "The perimeter of the rectangle = " << perimeter << " units." << endl; // displays the calculation of the perimeter system ("pause"); // REMOVE BEFORE RELEASE - testing purposes only return 0; }

• OnEditorActionListener called twice with same eventTime on SenseUI keyboard

  - by ydant

  On just one phone I am testing on (HTC Incredible, Android 2.2, Software 3.21.605.1), I am experiencing the following behavior. The onEditorAction event handler is being called twice (immediately) when the Enter key on the Sense UI keyboard is pressed. The KeyEvent.getEventTime() is the same for both times the event is called, leading me to this work-around: protected void onCreate(Bundle savedInstanceState) { [...] EditText text = (EditText)findViewById(R.id.txtBox); text.setOnEditorActionListener(new OnEditorActionListener() { private long lastCalled = -1; public boolean onEditorAction(TextView v, int actionId, KeyEvent event) { if ( event.getEventTime() == lastCalled ) { return false; } else { lastCalled = event.getEventTime(); handleNextButton(v); return true; } } }); [...] } The EditText is defined as: <EditText android:layout_width="150sp" android:layout_height="wrap_content" android:id="@+id/txtBox" android:imeOptions="actionNext" android:capitalize="characters" android:singleLine="true" android:inputType="textVisiblePassword|textCapCharacters|textNoSuggestions" android:autoText="false" android:editable="true" android:maxLength="6" /> On all other devices I've tested on, the action button is properly labeled "Next" and the event is only called a single time when that button is pressed. Is this a bug in Sense UI's keyboard, or am I doing something incorrectly? Thank you for any assistance.

• PHP download page: file_exists() returns true, but browser returns 'page not found'

  - by Chris

  I'm using PHP for a file download page. Here's a snippet of the problem code: if (file_exists($attachment_location)) { header($_SERVER["SERVER_PROTOCOL"] . " 200 OK"); header("Cache-Control: public"); // needed for i.e. header("Content-Type: application/zip"); header("Content-Transfer-Encoding: Binary"); header("Content-Length:".filesize($attachment_location)); header("Content-Disposition: attachment; filename=file.zip"); readfile($attachment_location); die("Hooray"); } else { die("Error: File not found."); } This code works absolutely fine when testing locally, but after deploying to the live server the browser returns a 'Page not found' error. I thought it might be an .htaccess issue, but all .htaccess files on the live server are identical to their local counterparts. My next guess would be the live server's PHP configuration, but I have no idea what PHP setting might cause this behaviour. The file_exists() function always returns true - I've checked this on the live server and it's always correctly picking up the file, its size etc., so it does have a handle on the file. It just won't perform the download! The main site is a Wordpress site, but this code isn't part of a Wordpress page - it's in a standalone directory within the site root. UPDATE: is_file() and is_readable() are both returning true for the file, so that's not the problem. The specific line that is causing the problem is: readfile($attachment_location) Everything up until that point is super happy.

• Memory increases with Java UDP Server

  - by Trevor

  I have a simple UDP server that creates a new thread for processing incoming data. While testing it by sending about 100 packets/second I notice that it's memory usage continues to increase. Is there any leak evident from my code below? Here is the code for the server. public class UDPServer { public static void main(String[] args) { UDPServer server = new UDPServer(15001); server.start(); } private int port; public UDPServer(int port) { this.port = port; } public void start() { try { DatagramSocket ss = new DatagramSocket(this.port); while(true) { byte[] data = new byte[1412]; DatagramPacket receivePacket = new DatagramPacket(data, data.length); ss.receive(receivePacket); new DataHandler(receivePacket.getData()).start(); } } catch (IOException e) { e.printStackTrace(); } } } Here is the code for the new thread that processes the data. For now, the run() method doesn't do anything. public class DataHandler extends Thread { private byte[] data; public DataHandler(byte[] data) { this.data = data; } @Override public void run() { System.out.println("run"); } }

• using same ids for many tags?

  - by gaurav rathor

  here is the example code that i was testing and i got confused that every one says that we can use or we should use only one time per id but i have testes using using it multiple times but its giving me the correct output. so what should i do. it is kinda working same like class for me in this example code: <html> <head> <style> #exampleID1 { background-color: blue; } #exampleID2 { text-transform: uppercase; } </style> </head> <body> <p id="exampleID1">This paragraph has an ID name of "exampleID1" and has a blue CSS defined background.</p> <p id="exampleID2">This paragraph has an ID name of "exampleID2" and has had its text transformed to uppercase letters.</p> <address id="exampleID1"> Written by W3Schools.com<br /> <a href="mailto:[email protected]">Email us</a><br /> Address: Box 564, Disneyland<br /> Phone: +12 34 56 78 </address> <blockquote id="exampleID1"> Here is a long quotation here is a long quotation here is a long quotation here is a long quotation here is a long quotation here is a long quotation here is a long quotation here is a long quotation here is a long quotation. </blockquote> </body> </html> please see the above code and answer me that why we should not use id selector two times in a page while its working fine.

• How to efficiently get highest & lowest values from a List<double?>, and then modify them?

  - by DaveDev

  I have to get the sum of a list of doubles. If the sum is 100, I have to decrement from the highest number until it's = 100. If the sum is < 100, I have to increment the lowest number until it's = 100. I can do this by looping though the list, assigning the values to placeholder variables and testing which is higher or lower but I'm wondering if any gurus out there could suggest a super cool & efficient way to do this? The code below basically outlines what I'm trying to achieve: var splitValues = new List<double?>(); splitValues.Add(Math.Round(assetSplit.EquityTypeSplit() ?? 0)); splitValues.Add(Math.Round(assetSplit.PropertyTypeSplit() ?? 0)); splitValues.Add(Math.Round(assetSplit.FixedInterestTypeSplit() ?? 0)); splitValues.Add(Math.Round(assetSplit.CashTypeSplit() ?? 0)); var listSum = splitValues.Sum(split => split.Value); if (listSum != 100) { if (listSum > 100) { // how to get highest value and decrement by 1 until listSum == 100 // then reassign back into the splitValues list? var highest = // ?? } else { // how to get lowest where value is > 0, and increment by 1 until listSum == 100 // then reassign back into the splitValues list? var lowest = // ?? } } update: the list has to remain in the same order as the items are added.

• C# XML Documentation Compiler Warning

  - by ImperialLion

  I am curious as to why I get a compiler warning in the following situation. /// <summary>This is class A /// </summary> public class A { /// <summary>This is the documentation for Method A /// </summary> public void MethodA() { //Do something } } /// <summary>This is class B /// </summary> public class B : A { /// <summary>This does something that I want to /// reference <see cref="MethodA"/> /// </summary> public void MethodB() { //Do something } } The warning states that "XML comment on 'B.MethodB()' has cref attribute 'MethodA' that could not be resolved." If B inherits from A shouldn't the compiler be able to see that method when generating the documentation without me specifying the parent class in the cref? If I change the cref to be cref="A.MethodA()" it works fine, but it seems like that's unnecessary and is a pain to do, especially if I have to go up more than one level. As a note to anyone testing this you have to be sure to "XML documentation file" checked in the Properties - Build in order to see the warning.

• a potentially dangerous request.form value was detected but validateinput(false) not working

  - by tonybolding

  I have installed VS2010 and MVC2 and testing a simple form using tinyMCE. When I post the contents of the textarea in tinyMCE I get the dreaded YSD and the message "a potentially dangerous....." No problem I thought - seen this before so I put the ValidateInput(false) on the controller but no joy - I still get the error. page code in edit.aspx is: <% using (Html.BeginForm()){ % <!-- Gets replaced with TinyMCE, remember HTML in a textarea should be encoded --> <textarea id="elm1" name="mceText" rows="15" cols="80" style="width: 80%"> &lt;p&gt; This is some example text that you can edit inside the &lt;strong&gt;TinyMCE editor&lt;/strong&gt;. </textarea> <br /> <input type="submit" name="save" value="Submit" /> <input type="reset" name="reset" value="Reset" /> <%} % and Controller action is: [AcceptVerbs(HttpVerbs.Post)] [ValidateInput(false)] public ActionResult Edit(string mceText) { return View(); } Any thoughts - (I know the code is not complete) been trying this for hours but everyone just says to use ValidateInput(false)

• Select All in Javascript (Firefox extension) not working right

  - by leezer3

  I'm having some problems with a select all/ none function. (I didn't write it, I'm trying to fix it!) It currently looks like this: rsfindmod.SelAll = function(){ document.getElementById("ListBox").selectAll(); document.getElementById("ListBox").focus(); } It's being used on a dynamically generated set of links, so there's no set number of items in this listbox. This seems to work most of the time, but randomly it only selects those which are visible at the time. Scrolling the list or hitting the button again seems to normally make it work as expected. My first (Obvious?) thought was to replace the function entirely with the one from this link for testing: http://viralpatel.net/blogs/2009/06/listbox-select-all-move-left-right-up-down-javascript.html Trouble is that I can't get this one to work whatsoever! This gives me the error that listbox.options is not defined Any thoughts please? I'm by no means certain whether it's the original function at fault, or something in the generation of this listbox.

• Using the read function to read in a file.

  - by robUK

  Hello, gcc 4.4.1 I am using the read function to read in a wave file. However, when it gets to the read function. Execution seems to stop and freezes. I am wondering if I am doing anything wrong with this. The file size test-short.wave is: 514K. What I am aiming for is to read the file into the memory buffer chunks at a time. Currently I just testing this. Many thanks for any suggestions, #include <stdio.h> #include <stdlib.h> #include <errno.h> #include <fcntl.h> #include <string.h> #include <unistd.h> int main(void) { char buff = malloc(10240); int32_t fd = 0; int32_t bytes_read = 0; char *filename = "test-short.wav"; /* open wave file */ if((fd = (open(filename, O_RDWR)) == -1)) { fprintf(stderr, "open [ %s ]\n", strerror(errno)); return 1; } printf("Opened file [ %s ]\n", filename); printf("sizeof(buff) [ %d ]\n", sizeof(buff)); printf("strlen(buff) [ %d ]\n", strlen(buff)); bytes_read = read(fd, buff, sizeof(buff)); printf("Bytes read [ %d ]\n", bytes_read); return 0; }

• Batch Inserts And Prepared Query Error

  - by ircmaxell

  Ok, so I need to populate a MS Access database table with results from a MySQL query. That's not hard at all. I've got the program written to where it copies a template .mdb file to a temp name and opens it via odbc. No problem so far. I've noticed that Access does not support batch inserting (VALUES (foo, bar), (second, query), (third query)). So that means I need to execute one query per row (there are potentially hundreds of thousands of rows). Initial performance tests show a rate of around 900 inserts/sec into Access. With our largest data sets, that could mean execution times of minutes (Which isn't the end of the world, but obviously the faster the better). So, I tried testing a prepared statement. But I keep getting an error (Warning: odbc_execute() [function.odbc-execute]: SQL error: [Microsoft][ODBC Microsoft Access Driver]COUNT field incorrect , SQL state 07001 in SQLExecute in D:\....php on line 30). Here's the code I'm using (Line 30 is odbc_execute): $sql = 'INSERT INTO table ([field0], [field1], [field2], [field3], [field4], [field5]) VALUES (?, ?, ?, ?, ?, ?)'; $stmt = odbc_prepare($conn, $sql); for ($i = 200001; $i < 300001; $i++) { $a = array($i, "Field1 $", "Field2 $i", "Field3 $i", "Field4 $i", $i); odbc_execute($stmt, $a); } So my question is two fold. First, is there any idea on why I'm getting that error (I've checked, and the number in the array matches the field list which matches the number of parameter ? markers)? And second, should I even bother with this or just use the straight INSERT statements? Like I said, time isn't critical, but if it's possible, I'd like to get that time as low as possible (Then again, I may be limited by disk throughput, since 900 operations/sec is high already)... Thanks

• Rails: associate model with two of its kind

  - by Patrick Oscity

  hi all, im trying to do this: class Event < ActiveRecord::Base belongs_to :previous_event has_one :event, :as => :previous_event, :foreign_key => "previous_event_id" belongs_to :next_event has_one :event, :as => :next_event, :foreign_key => "next_event_id" end because i want to enable the user to repeat events and change multiple oncoming events at the same time. what am i doing wrong, or is there another way of doing this? somehow i need to know about the previous and the next event, don't i? when i'm testing this in the consolewith Event.all[1].previous_event, i get the following error: NameError: uninitialized constant Event::PreviousEvent from /Library/Ruby/Gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:105:in `const_missing' from /Library/Ruby/Gems/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:2199:in `compute_type' from /Library/Ruby/Gems/1.8/gems/activesupport-2.3.5/lib/active_support/core_ext/kernel/reporting.rb:11:in `silence_warnings' from /Library/Ruby/Gems/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:2195:in `compute_type' from /Library/Ruby/Gems/1.8/gems/activerecord-2.3.5/lib/active_record/reflection.rb:156:in `send' from /Library/Ruby/Gems/1.8/gems/activerecord-2.3.5/lib/active_record/reflection.rb:156:in `klass' from /Library/Ruby/Gems/1.8/gems/activerecord-2.3.5/lib/active_record/associations/belongs_to_association.rb:49:in `find_target' from /Library/Ruby/Gems/1.8/gems/activerecord-2.3.5/lib/active_record/associations/association_proxy.rb:239:in `load_target' from /Library/Ruby/Gems/1.8/gems/activerecord-2.3.5/lib/active_record/associations/association_proxy.rb:112:in `reload' from /Library/Ruby/Gems/1.8/gems/activerecord-2.3.5/lib/active_record/associations.rb:1250:in `previous_event' from (irb):2 what is going wrong here? thanks a ton for your help.

• is_dir does not recognize folders

  - by Rakoon

  Hi I am trying to make a function that scans a folder for subfolders and then returns a numeric array with the names of those folders. This is the code i use for testing. Once i get it to print out the folder names and not just "." and ".." for present and above folder all will be well, and I can finish the function. <?php function super_l_getthemes($dir="themes") { if ($handle = opendir($dir)) { echo "Handle: {$handle}\n"; echo "Files:\n"; while (false !== ($file = readdir($handle))) { echo "{$file}<br>"; } closedir($handle); } ?> The above code works fine, and prints out all the contents of the folder: files, subfolders and the "." and ".." but if i replace: while (false !== ($file = readdir($handle))) { echo "{$file}<br>"; } with: while (false !== ($file = readdir($handle))) { if(file_exists($file) && is_dir($file)){echo "{$file}";} } The function only prints "." and ".." , not the two folder names that I'd like it to print. Any help is appreciated.

• How do I manipulate the format on a DataGridView that is bound to a Data Source?

  - by Jack Johnstone

  I´m using SQL Server 2005 and Visual Studio 2008, C#. In the data source (the SQL Server data table) I use the DateTime format mm/dd/yyyy, however, in a forms overview (DataGridView) users would like to see a completely other format, with year, week number and day number of week (yyww,d) which is in string format. I´ve created an algorithm for the transformation between values (date to weekday), but can I populate the affected cells with yyww,d (string) instead of mm/dd/yyyy (DateTime)? This is what I´ve been testing out, without success (and note, it´s on the last line the problem becomes obvious, as the cell value won´t accept a string on runtime - it still wants to be a DateTime...) private void DataGridViewQueryFindRequests_CellFormatting( object sender, DataGridViewCellFormattingEventArgs e) { string weekAndDay = ""; DataGridViewCell cell = DataGridViewQueryFindRequests.Rows[e.RowIndex].Cells[e.ColumnIndex]; if (cell.ColumnIndex == 13 && cell.Value == null) mEmptyRow = true; if ((cell.ColumnIndex == 14 || cell.ColumnIndex == 15) && !mEmptyRow) { weekAndDay = ClassWeeksAndDates.dateToWeekNumber(Convert.ToDateTime(cell.Value)); cell.ValueType = typeof(string); cell.Value = weekAndDay; } }

• Accessing to Request object will lead to ReadEntityBody to return 0 (in a HttpHandler class)

  - by EBAG

  I created a httpHandler that successfully implements IHttpHandler for handling file uploads. It works perfectly fine. You send the file with the form, the class receives it and will save it to hard disk. It reads chunks of file with ReadEntityBody function of HttpWorkerRequest class. Here is the situation i'm faced with.If at any stage before trying to read the file with ReadEntityBody, I try to access Request object (even Request.InputStream.Length!) ReadEntityBody would return 0 means it won't read from file stream. After further testing I found out the reason behind it. Accessing to Context.Current.Request object will trigger some sort of functionality that will cause asp.net to handle file uploads at that moment by it's own! I believe this is a bug. for example exactly after this line of code, asp.net will upload the file completely, and so there will be no stream for ReadEntityBody to read from later. int FileSize = context.Request.InputStream.Length; Can anybody tell how to stop this?

• OpenType Font Parsing for Pleasure and Profit (anyone understand these damn tables?)

  - by mustISignUp

  So, this is mainly for fun, I'm poking around and trying to find my way inside a few fonts and i have a few questions i'd reeally appreciate some help on if anyone has done this kind of stuff. cmap table The fonts i am testing with contain several cmap subtables of different formats. I can read them, but i don't understand which i should be using. ie. what is the strategy for choosing the most appropriate subtable? Does this even make sense? glyf table This is really making my head hurt. I'm going by what is on here. Looking at the second table on that page.. I've got 'n' endPtsOfContours, 'n' instructions and 'n' flags but it is not clear to me if i have the same number of flags as contours (i know how many contours i have). Then, to make matters worse..(fun!) i have an array of xCoords and an array of yCoords. These arrays seem to be of indeterminate length and may contain data of either BYTE or SHORT but we are not going to tell you which.. Thanks to anyone willing to shed some light.

• How would you structure your workflow for a web application ?

  - by cx42net

  Hi ! When designing a web application (or something else), it's good to have a workflow, and it's better to have a well ordered one. Starting with this idea in mind, I'd like to know what is your process from having an idea to maintain this great working project. For me actually, the process is the following one : Having the idea Checking this project already exists, and how it works Describing on a paper its functionalities finding a good and adequate name for this (and checking the domain availability with WHOISMyProject) Making a quick layout of the project on a paper Designing the project (via TheGimp, Photoshop, etc) Making a complete mockup of each pages Developing a prototype of the client-side application (with false datas) Developing the server side Testing Making the documentation/help/faq Releasing the project Maintaining it. Would you change the order of some points ? add/remove some ? I would please to know how you do that. I'm looking to set up a perfect workflow in order to make my project become real in the best way possible. Thank you for your opinion !

• odd behavior when checking if radio button selected in jQuery

  - by RememberME

  I had the following check in my jQuery which I thought was working fine to see if a radio button was checked. if ($("input[@name='companyType']:checked").attr('id') == "primary") { ... } Here's the radiobuttons: <p> <label>Company Type:</label> <label for="primary"><input onclick="javascript: $('#sec').hide('slow');$('#primary_company').find('option:first').attr('selected','selected');" type="radio" name="companyType" id="primary" checked />Primary</label> <label for="secondary"><input onclick="javascript: $('#sec').show('slow');" type="radio" name="companyType" id="secondary" />Subsidiary</label> </p> Then, it suddenly stopped working (or so I thought). I did some debugging and finally realized that it was returning an id of "approved_status". Elsewhere on my form I have a checkbox called "approved_status". I realized that when I originally tested this, I must have testing it on records where approved_status is false. And, now most of my approved_statuses are true/checked. I changed the code to this: var id = $("input:radio[@name='companyType']:checked").attr('id'); alert(id); if (id == "primary") { And it's now properly returning "primary" or "secondary" as the id. So, it is working, but it seems that it's not checking the name at all and now just checking radio buttons. I just want to know for future use, what's wrong with the original code b/c I can see possibly having 2 different radio sets on a page and then my new fix probably wouldn't work. Thanks!

• What's a good way to organize a large collection of personal scripts using git?

  - by spooky note

  I have a large collection of my personal scripts that I would like to start versioning using Git. I've previously organized my code as follows: ~/code/python/projects/ (for large stuff, each project contained in an individual folder) ~/code/python/scripts/ (single file scripts all contained in this directory) ~/code/python/sandbox/ (my testing area) ~/code/python/docs/ (downloaded documentation) ~/code/java/... (as above) Now i'm going to start versioning my code using git, so that I can have history and backup all my code to a remote server. I know if I were using SVN I would just keep my entire "~/code/" directory in a large repository, but I understand this is not a good way to do things with Git. Most info I've seen online suggests keeping all my project folders in a single place (as in, no separate directories for python or java) with each project containing it's own git repository, and simply having a "snippets" directory containing all single-file scripts/experiments that can be converted into projects at a later date. But I'm not sure how I feel about consolidating all of my code directories into one area. Is there a good way to keep my separate code directories intact, or is it not worth the effort? Maybe I'm just attached to the separate code directories because I've never known anything else... Also (as a side note), I'd like to quickly be able to see a chronological history of all my projects and scripts. So I can see which projects I created most recently. I used to do this by keeping a number at the beginning of all my projects, 002project, 003project. Is there automatic or easy way to do this in git without having to add a number to all of the project names? I'm open to any practical or philosophical code organizing advice you have. Thanks!!!

• Adobe popping out of the browser

  Hi, Im building a web application that displays a xfdf document. When we are testing in adobe 5 and we can't stop adobe opening outside the webpage. The user clicks the report and it should open in the browser but instead it opens in adobe it appears to work in everything but adobe 5. We have previously done this with out any problems. Any ideas? This is a snippet of the xfdf <?xml version="1.0" encoding="UTF-8" ?><xfdf xmlns="http://ns.adobe.com/xfdf/" xml:space="preserve"> <fields> <field name="fld_AccomAttic"> <value>0</value> </field> <field name="fld_AccomBathroom"> <value>1</value> </field> <field name="fld_AccomBedrooms"> <value>3</value> </field> <field name="fld_AccomCellars"> <value>0</value> </field> <field name="fld_AccomGarages"> <value>Off</value> </field><f href="{report name}"/></xfdf> Any help would be great Sp

• What's the difference between UI development and front-end development?

  - by Nick Lowman

  I'm a front-end developer and really enjoy jQuery and JavaScript. I've built a lot a websites, done some good jQuery work and built a few JavaScript based applications and would really like to get in UI development. Or so I thought. I guessed it would be pretty similar to what I already do except maybe a little more JavaScript heavy but when I looked into it all the job specs said I needed to know about Scrum or Agile development, knowledge of testing frameworks and a good knowledge of JavaScript frameworks and custom events. So, from the specs I get the idea that a UI developer is actually a dedicated JavaScript developer. Is that the case? I understand (with much help from the users on stackoverflow), about JavaScript OO, inheritance, closures, custom events, debugging in Firefox or Aptana etc, and the people I work with seem to think I pretty OK at what I do but clearly my knowledge is not good enough to go for UI jobs. If anyone could tell me a little more about UI development and if there are any good resources for learning about it I would be most grateful as I couldn't find much on the internet.

• What is the best way to properly test object equality against an array of objects?

  - by radesix

  My objective is to abort the NSXMLParser when I parse an item that already exists in cache. The basic flow of the program works like this: 1) Program starts and downloads an XML feed. Each item in the feed is represented by a custom object (FeedItem). Each FeedItem gets added to an array. 2) When the parsing is complete the contents of the array (all FeedItem objects) are archived to the disk. The next time the program is executed or the feed is refreshed by the user I begin parsing again; however, since a cache (array) now exists as each item is parsed I want to see if the object exists in the cache. If it does then I know I have downloaded all the new items and no longer need to continue parsing. What I am learning, I think, is that I can't use indexOfObject or indexOfObjectIDenticalTo: because these really seem to be checking to see that the objects are using the same memory address (thus identical). What I want to do is see if the contents of the object are equal (or at least some of the contents). I've done some research and found that I can override the IsEqual method; however, I really don't want to iterate/enumerate through the entire cache contents table for every newly parsed XML FeedItem. Is iterating through the collection and testing each one for equality the only way to do this or is there a better technique I am not aware of? Currently I am using the following code though I know it needs to change: NSUInteger index = [self.feedListCache.feedList indexOfObject:self.currentFeedItem]; if (index == NSNotFound) { }

• Fatal error: Allowed memory size exhausted...

  - by Nano HE

  HI, I upload my php testing script to online vps server just now. The script used to parse a big size XML file(about 4M, 7000Lines). But my IE explorer show the online error message below. Fatal error: Allowed memory size of 16777216 bytes exhausted (tried to allocate 77 bytes) in /var/www/test/result/index.php on line 26 I am sure I already tested the php script on localhost successfully. Is there any configuration need be enable/modify on my VPS? Such as php.ini or some setting for apache server? I just verified there are about 200M memory usage are avaliable for my VPS. How can I fix this? ...... function startElementHandler ($parser,$name,$attrib){ global $usercount; global $userdata; global $state; // Line #26; //Debug //print "name is: ".$name."\n"; switch ($name) { case $name=="_ID" : { $userdata[$usercount]["first"] = $attrib["FIRST"]; $userdata[$usercount]["last"] = $attrib["LAST"]; $userdata[$usercount]["nick"] = $attrib["NICK"]; $userdata[$usercount]["title"] = $attrib["TITLE"]; break; } ...... default : {$state=$name;break;} } }
