<p>What sort of work rate will employers be expecting a new graduate to work at? My employer hasn't said anything but I feel like I am taking much longer than they anticipated - perhaps even regretting that the have employed me in the first place. Also, I am asking for help with logic and some best ways to tackle some problems and I also feel they think I should know more than I should. Again what would an employer be expecting from the level of a recent graduate. </p>
<p>I want to be as good as I can and learn as much as possible but I constantly feel under pressure as I keep thinkin I should be getting through mug more work than I currently am. Is this a common feeling in new programmers and how would my employer approach it if I wasn't performing up to their expectations. Like I said, nothing had been mentioned but I do feel they are wondering why they bothered to hire me. </p>
<p>Some advice on this from experienced developers would be great. </p>

When you look into the console, you can see that the exception's trace text is mixed up with normal output done by System.out. I understand that these two are different streams (System.out and System.err) and I guess that the output of the exception is done internally by some other thread, that is why it is mixed up.</p>

<li><p>Create a script that receives said text as a POST and sends it back with the right Content Headers. This is no desirable because we would be POSTing 250k, which would be slower than:</p></li>

I am struggling to work out whether I'm doing things the "right" way or just making life difficult for myself.</p>
<p>The app displays a series of connected nodes on the screen, similar to a mind-map. I want to be able to tap the nodes in order to edit them. When the map of nodes becomes larger than the screen, I need to be able to scroll on both X and Y axes as needed to see the whole map. Image of current implementation at <a href="http://ubergeek.org.uk/images/nodetest.png" rel="nofollow">http://ubergeek.org.uk/images/nodetest.png</a>.</p>
<p>Currently I don't have scrolling working, however I assume that I can do that by making the root view a ScrollView and sticking an AbsoluteLayout inside that (though it's deprecated, I wish to place objects at specific X/Y coordinates).</p>
<p>The nodes themselves are currently each a pair of roundrects (one for the outline and one for the fill) and a drawText and are being drawn in the main activity's onDraw(). In order to make these clickable buttons I believe I need to create a custom view for the button in order to use its onClick() events. I can then create a view object for each of my nodes and add them to the AbsoluteLayout view.</p>
<p>Does this sound like a reasonable way to do it in Android, or is this a horrible abuse of the API? :)</p>
<p>Thanks!</p>

1,158,852 | 1,158,853 | How to measure javascript parse time | <p>In our company we combine every Javascript file into one big (around 700kb but growing) minified and gzipped Javascript file. I am trying to assess the performance differences between using one big Javascript file for every page (minified and gzipped) and using several Javascript files, one for each page.</p>
<p>An obvious difference is that the big Javascript file can be cached by browsers after it has been loaded on the first page request and creates little overhead thereafter while when using several js files, there will be at least one uncached get request on each different page. So I would be trading a slower first initial page load for slower successive initial page loads.</p>
<p>In order to find out when the slow initial page load (using one big Javascript file) will become problematic enough to justify the work of breaking up the combined file into smaller files and changing our build procedure, I would like to find out how long it takes for the code to be parsed, so I can estimate the total loading and parsing time.</p>
<p>So far my approach has been to add a script tag to a test page which takes the current time, appending a bigish script with Javascript and after that meassuring time again like so:</p>
<pre><code>var head = document.getElementsByTagName('head')[0];
var script = document.createElement('script')
script.setAttribute('type', 'text/javascript');
script.src = 'path/700kbCombineFile.js';
start_time = new Date().getTime();
head.appendChild(script);
</code></pre>
<p>At the end of 700kbCombineFile.js, I appended:</p>
<pre><code>console.log(new Date().getTime() - start_time)
</code></pre>
<p>Then I subtract the network transfer time obtained from firebug and receive approximately 700ms for a 700 kb file and about 300ms for a 300 kb file.</p>
<p>Does this approach make sense? Why not? Is there a better way/any tools for doing this?</p>

4,529,025 | 4,529,026 | javascript get child by id | <pre><code><div onclick="test(this)">
Test
<div id="child">child</div>
</div>
</code></pre>
<p>I want to change the style of the child div when the parent div is clicked. How do I reference it? I would like to be able to reference it by ID as the the html in the parent div could change and the child won't be the first child etc.</p>
<pre><code>function test(el){
el.childNode["child"].style.display = "none";
}
</code></pre>
<p>Something like that, where I can reference the child node by id and set the style of it.</p>
<p>Thanks.</p>
<p>EDIT: Point taken with IDs needing to be unique. So let me revise my question a little. I would hate to have to create unique IDs for every element that gets added to the page. The parent div is added dynamically. (sort of like a page notes system). And then there is this child div. I would like to be able to do something like this: el.getElementsByName("options").item(0).style.display = "block";</p>
<p>If I replace el with document, it works fine, but it doesn't to every "options" child div on the page. Whereas, I want to be able to click the parent div, and have the child div do something (like go away for example).</p>
<p>If I have to dynamically create a million (exaggerated) div IDs, I will, but I would rather not. Any ideas?</p>

5,869,591 | 5,869,592 | JQuery and multiple radio button groups problem | <p>I am having trouble using JQuery to work with multiple radio button groups. The JQuery code, for some reason, cannot tell the difference between the two groups of radio buttons and cannot tell which group of radio button I clicked on.</p>
<p>Here is the HTML code:</p>
<pre><code><!-- Radio button group 1 -->
<input type="radio" name="group_1" value="full_day_ticket"/>
<input type="radio" name="group_1" value="half_day_ticket"/>
<!-- Radio button group 2 -->
<label><input type="radio" name="group_2" value="boarder"/> Snowboard</label>
<label><input type="radio" name="group_2" value="skier"/> Ski</label>
</code></pre>
<p>And the JQuery code is as follows:</p>
<pre><code>$("input:radio[@name='group_2']").click(function() {
alert('group 2 clicked');
}
</code></pre>
<p>Now when I click on the radio buttons named 'group_1', JQuery thinks that I clicked on a radio button in 'group_2' and displays the alert window. For some reason, it seems that JQuery is not recognising the @name='group_2' filter and captures clicks on all radio buttons on the page, instead of just the radio buttons named 'group_2'.</p>
<p>Has anyone come across this problem before? Or am I doing something stupid?</p>

The problem I am facing is mostly to due with user input from the keyboard. I need to be able to take the user input to decide what function to call and what arguments to give the function. For example something like <code>add 5</code> would call the add function with the argument 5. At first I tried overloading the >> operator to take both a string and an int but the problem I ran into was the program was unable to take input without the int such as <code>deletemax</code> so I had to throw that idea out. So now I am back to tokenizing the input but we are not allowed to use Boost for this program so I came up with something like this using sstream</p>
<pre><code> bool out = false;
string token;
string In;
int num;
do
{
cout << "heap> ";
cin >> In;
istringstream iss(In);
while(getline(iss, token, ' '))
{
cout << token << endl; //I know this is incorrect but just not what to replace it with
}
out = ProcessCommand (token, num); //Takes string and int to call correct functions
} while (out != true);
</code></pre>
<p>The problem lies in that I'm not quite sure how to correctly tokenize the string so I can get 2 string and convert the second string to an int. Can anyone offer me some assistance? I would greatly appreciate it. Also if there is a better way to go about this than I am trying I would also like to hear it.</p>
<p>Thanks for any help you can give me.</p>

<p>I am not going to ask questions step by step through my whole assignment, but I want to make sure that this is the way to go about one of the next tasks. I have written the following, which compiles fine (the purpose is to check the string to make sure that it is numeric, and the user may have also entered the ISBN as a number with or without dashes):</p>
<pre><code> private String validateISBN(String bookNum)
{
String[] book;
int j=0;
for ( int i=0;i<bookNum.length();i++)
if (character.isDigit(bookNum.charAt[i]))
bookNum.charAt[i]=book[j];j++;
</code></pre>
<p>I haven't written the next part, which has to allow for an X as the last digit in the string (which is apparently how ISBN numbers work). I would assume that if the above is correct (or close), that all i need to do is check that the ninth character is a digit or an X, by writing something like:
if book[9] isDigit() || if book[9] == "x" || if book[9] == "X";</p>

12,921 | 12,922 | Dynamically Return a Class of a Type Determined During a Method Call via Class.forName() | <p>I know that I can dynamically determine the return type of a method by passing in a class and then declaring that class as the return type, as in the following example:</p>
<pre><code>public static <returnType> returnClass dynamicConstructor (Class<returnType> returnClass){
//Dynamically construct an object using a zero parameter constructor
return (returnClass) object;
}
</code></pre>
<p>The code that would be called would be:</p>
<pre><code>DynamicConstructor.construct(constructedClass);
</code></pre>
<p>This code is nice because when you're calling the method in code, it's simple and encapsulated. However, I would like to take it one step further and make the parameter a string containing the full class name, then have the method determine the type of the object via <code>Class.forName(className)</code>. The trouble with this is that I can't figure out how to return the type as determined later on. Using method overloading, the code I have is:</p>
<pre><code>public static ?????? dynamicConstructor (String className){
try {
return dynamicConstructor(Class.forName(className));
} catch (ClassNotFoundException e) {
System.out.println("Could not find class at path " + classPath);
e.printStackTrace();
return null;
}
}
</code></pre>
<p>The problem is that I have no idea what to put in the part labeled <code>??????</code>. I want to be able to somehow reference the class determined by <code>Class.forName(className)</code>. Is this possible?</p>

5,982,460 | 5,982,461 | Put javascript in one .js file or break it out into multiple .js files? | <p>My web application uses jQuery and some jQuery plugins (e.g. validation, autocomplete). I was wondering if I should stick them into one .js file so that it could be cached more easily, or break them out into separate files and only include the ones I need for a given page.</p>
<p>I should also mention that my concern is not only the time it takes to download the .js files but also how much the page slows down based on the contents of the .js file loaded. For example, adding the autocomplete plugin tends to slow down the response time by 100ms or so from my basic testing even when cached. My guess is that it has to scan through the elements in the DOM which causes this delay.</p>
