5,454,401 | 5,454,402 | Upload file from client machine to server - prepopulate file picker path? | <p>I'd like to upload a file from a client machine to my server. The user would have to specify the file to upload as I understand it, using a form that looks like:</p>
<pre><code><input type="file" name="datafile" size="40">
</code></pre>
<p>This pops up a native file picker, which is great. The problem I'm having is that it's a real pain (for most users) to go looking around their machine for the file I'm interested in. Is there a way I can initialize the file picker with a path to make it more convenient for the user? Like I know some users will be on a windows machine, so I could prepopulate the picker by already sending them to the My Documents folder for example.</p>
<p>I don't see how this is possible, just wondering if something like that exists,</p>

5,015,031 | 5,015,032 | Forced password change after x days stuck in a loop | <p>I am implementing a forced password change after 90 days for a web application - at the top of an application header file which is called on every page I check the age of the password and if it is over 90 days force the user to a password change page. This all works fine.</p>
<p>The problem is the password change page also calls the header page which does the check so it gets the same look and feel as the rest of the site but, of course, it then sticks in a never ending loop of check and redirect - what is the best way to prevent this? I don't want to have to have the password change page with no formatting, nor as a pop up and I ideally don't want to use a different template header without the password check as I will forget to update the second one when I make changes.</p>
<p>How else can I approach this? I want to make sure that the user cannot do anything other than change their password once they pass the 90 day mark.</p>
<p>Thanks

var sum = 0;
for( var i in p1 ){
sum += Math.pow( p1[i] - p2[i], 2 );
}
return Math.sqrt( sum );
};
</code></pre>
<p>The overall program was quite slow taking on average 7sec to execute. After some profiling I rewrote the above function this</p>
<pre><code>var euclideanDistance = function( p1, p2 ) { // p1.length === p2.length == 3
var sum = 0;

1,622,622 | 1,622,623 | Wait for a network chage in a service, in order to download updates | <p>I have a service which periodically downloads some updates from a web site.
Default period is long, about 10 mins and I do that with an AlarmManager which starts this service.</p>
<p>Network can be on or off, <strong>in case it's off service should download news as soon as network returns on</strong>, because interval is long and, in the worst case, you could have to wait 20 min till next update.</p>
<p>I made a network state broadcast receiver, and, with little code I made a NetworkListener interface:</p>
<pre><code>public interface NetworkStateListener {
public void onNetworkOn();
public void onNetworkDown();
}
</code></pre>
<p>So my service has these 2 methods and <strong>can know when network goes on or off</strong>.</p>
<p>My idea is the following: in the onStart() method I spawn a new thread: if network is off thread waits, otherwise downloads. When onNetworkOn() is called I call a notify():</p>
<pre><code>private boolean threadWaiting; //a flag so that I don't spawn multiple threads
public int onStartCommand(Intent intent, int flags, int startId) {
if(!threadWaiting){//if already a thread waiting do nothing and exit
Thread t = new Thread(new Runnable(){
@Override
public void run() {
synchronized(binder){
while(!isNetworkOn())
try {
threadWaiting = true;
binder.wait();
}catch(InterruptedException ex){
ex.printStackTrace();
}
}
// blocks until network connection is available
threadWaiting = false;
//... operations ...
</code></pre>
<p>And this is onNetworkOn() method:</p>
<pre><code>public void onNetworkOn() {
synchronized(binder){
binder.notify();
}
</code></pre>
<p>is this the right way to proceed?</p>

<p>Hi guys,</p>
<p>I have a question about the arguments passing in Java, I read it from a book <em>"In Java the arguments are always passed by value"</em>, what does this mean? </p>
<p>I have no experience of C++ and C, so it is a little bit hard for me to understand it.
Can anyone explain me? </p>

4,455,452 | 4,455,453 | ClearInterval() and SetInterval() | <p>So in my javascript code, there is a part where if the user clicks on the checkbox I need to change the time delay used by <code>setInterval()</code>. At the moment, I used the <code>onchange</code> handler on the checkbox. Whenever the checkbox is changed, I call <code>clearInterval()</code> and <code>setInterval()</code>. I have the interval id as a global variable. Now if the user changes the checkbox before i have made my call to <code>clearInterval()</code> I expected there to be some issues, but nothing happened. Is there a better way to do this or is this way considered standard? Is there a way to check if there is an <code>interval</code> in existence?</p>
<p>PS.
I'm very new to Javascript, started it about 5 hours ago.</p>
