5,834,560 | 5,834,561 | Running an Activity a certain interval before going to sleep | <p>I am currently working on customizing an Android system and would like that, a few minutes before going to sleep, a given Activity is run, with the same premises as the sleep function (e.g. if the user performs any action, its timer gets reset).</p>
<p>For instance, let's say that we set its timer to 5 minutes and the device is set to go to sleep after 10 minutes. This means that, as long as there is no user input (or wakelocks acquired etc.), after 5 minutes my Activity is started, and after another 5 minutes the device enters sleep mode (think of it similar to a screensaver).</p>
<p>My initial searches have lead me to the PowerManagerService class, where the ACTION_SCREEN_OFF is broadcast, but the general idea of the code there has so far eluded me.</p>
<p>Any help would be appreciated.
Thank you.</p>

47,060 | 47,061 | How can I send a date from one site to other sites? | <p>I'm not much of a php coder, mainly use VB. But I had a problem with one of my apps. To make it more secure I would need each php parameter to go through one site. Here is an example of what I mean:</p>
<ul>
<li>Application loads</li>
<li>Sends ip and location to 2 servers (a.php & b.php)</li>
</ul>
<p>The problem so far is that the PC is making direct connections to these pages. What I was trying to do is make it so that it only sends one command to <code>z.php</code> and the page <code>z.php</code> would send the data to <code>a.php</code> and <code>b.php</code>.</p>
<p>My question is: How would I set up <code>z.php</code>?</p>

1,519,863 | 1,519,864 | User-facing numbers: implementing them efficient, "operational" and round-off safe? | <p>I have something similar to a <strong>spreadsheet column</strong> in mind. A spreadsheet column has transparent data typing: text or any kinds of numbers.</p>
<p>But no matter how the typing is implemented internally, they allow <strong>roundoff-safe</strong> operations; eg adding up a column of hundreds of numbers with decimal points, and other arithmetic operations. And they do it efficiently too.</p>
<p>What way of handling numbers can make them:</p>
<ol>
<li>transparent to the user</li>
<li>round-off safe</li>
<li>support efficient arithmetic, aggregation, sorting</li>
<li>handled by datastores and applications with Java primitive types?</li>
</ol>
<hr>
<p>I have in mind, using a 64b <code>long</code> datatype that is internally multiplied by 1000 to provide 3 decimal places. For example <code>123.456</code> is internally stored as <code>123456</code>, <code>`1</code> is stored as <code>1000</code>. Reinventing floating point numbers seems clunky; I have to reinvent multiplication, for example.</p>
<hr>
<p><strong>Miscellany:</strong> I actually have in mind a document tagging system. A number tag is conceptually similar to a spreadsheet column that is used to store numbers.</p>
<p>I do want to know how spreadsheets handle it, and I would have titled the question as such.</p>
<p>I am using two datastores that uses Java primitive types. Point #4 wasnt hypothetical.</p>

4,327,139 | 4,327,140 | Is it a mistake to return a list if the return type is an enumerable | <p>I have often the case where I want to return an <code>Enumerable<T></code> from a method or a property. To build the returning <code>Enumerable<T></code>, I use a <code>List<T></code>-instance. After filling the list, I return the list.</p>
<p>I always thought that this is enough. But it exists the possibility that the caller casts the resulting <code>Enumerable<T></code> back into the <code>List<T></code> and begins to work further with it. If in a later time I change the implementation of my method, the caller’s code will fail. To avoid this, I could return list.ToArray or make a read-only list before returning it to the caller. But for me this seems to be a big overkill. What do you think?</p>
<p>Please note, <strong>I never will return an internally used list</strong> so that the caller can change my objects internal state. The question is only about a short living list that is built temporary to hold the return values.</p>
<pre><code>IEnumerable<string> GetAList() {
List<string> aList = new List<string>();
aList.Add("a");
aList.Add("b");
return aList;
}
IEnumerable<string> GetAList() {
List<string> aList = new List<string>();
aList.Add("a");
aList.Add("b");
return aList.ToArray<string>();

<p>It works if I explicitly use the names but I'd like it to work dynamically. Unfortunately I just am not understanding how to correctly use these arguments.</p>
<p>Right now the first document statement works (form name and button name are used), why doesn't the second, where arguments are used? I know from the alert that the form name isn't correct and can't be used as is but this won't work even if I explicitly name the form but use the passed button name which does appear correct.</p>
<p>I know this must be javascript 101 but I run into this time and again and am just not getting what's what. Anyone willing to explain this to me?</p>

<p>Why Java sets don't have methods for retrieving an element that is equal to provided?</p>
<p>For example, I need to create an object pool, something like String.intern() method (yes, I know that this is usually done with weak references), so I need to create a Map and do map.put(o,o) to put my unique object if they are not present in the map.

2,904,202 | 2,904,203 | detect change to window.name | <p>I'm trying to find a good way to detect when the window's name has changed. It is easy enough to do with <code>setInterval</code> like this:</p>
<pre><code>var old_name = window.name;
var check_name = function() {
if(window.name != old_name) {
console.log("window name changed to "+window.name);
old_name = window.name;
}
}
setInterval(check_name, 1000);
</code></pre>
<p>However, <code>setInterval</code> is more than a little hacky and may come with a significant (1s in this case) time delay before detecting changes. Is there any kind of event or clever bit of JS that can fire a function when the window name changes?</p>
<p>Thanks!
Joseph Mastey</p>
<hr>
<p>EDIT:</p>
<p>Unfortunately, I don't have control over the code that will be changing the window name, which is in a way the entire point of the exercise. Having looked at <a href="http://samy.pl/evercookie" rel="nofollow">evercookie</a> and other posts about storing data in the window name as a way to track users, I've decided that this isn't really acceptable to me. So, I'm creating a Greasemonkey script (actually, the Chromium version of a greasemonkey script) to prevent this sort of data leakage.</p>
<p>As an aside, I did find some magic functionality that Chromium implements that goes a long way towards what I want. JS provides magic getters and setters that can be used like this:</p>
<pre><code>window.__defineSetter__("name", function(nm) { console.log("intercepted window.name attempt: "+nm); });
window.__defineGetter__("name", function() { return ""; });
</code></pre>
<p>If I run this on the console, I can successfully hijack sets of the window name. However, running this code as a Chromium script (at least any variant I've tried so far) does not seem to be able to override the window behavior.</p>

1,950,113 | 1,950,114 | xmlrpclib connection gives timeout error even with setglobaltimeout(None) | <p>Most of what I've seen on here is people trying to add timeouts to their connections - I actually have the opposite problem. I'm calling socket.setglobaltimeout(None) and making a custom transport with no timeout:</p>
<pre><code>class TimeoutTransport(xmlrpclib.Transport):
timeout = None
def set_timeout(self, timeout):
self.timeout = timeout
def make_connection(self, host):
h = httplib.HTTPConnection(host, timeout=self.timeout)
return h

<p>(I'm not actually sure this is right, I saw conflicting things online)</p>
<p>Despite this, I'm still seeing timeout errors on long xmlrpc calls (it's doing a recursive search through hosts). Am I missing something? There's probably a more elegant solution than leaving xmlrpc calls hanging, but I'm running short on time, and can't do a major rework.</p>

263,002 | 263,003 | Apache HttpComponents and Java NIO | <p>I read something about Java NIO, so i now know there is thing called selector, where i can register channels and let selector check for some events on those channels. One of event is OP_WRITE. If selector detect OP_WRITE key on some channel, it tell me that channel is ready for writing to it. </p>
<p>I need to do one application, which will be used through HTTP protocol, so i am studying Apache HTTP Components library now. In this library is interface called HttpAsyncExchange and it is implemented by class Exchange. Instance of Exchange class have method called submitResponse and if this method is invoked, then underlying socketChannel will be marked as OP_WRITE. So instead of sending response directly to client after resolving request, the response is sended later when selector return me that underlying socketChannel because of event OP_WRITE on it. </p>
<p>I dont understand where is benefit of "marking" socketChannel as OP_WRITE and sending response later, instead of sending response directly, can anyone explain me? Sorry for my bad english.</p>

1,479,637 | 1,479,638 | Python - how to handle outcome variables that are conditional set correctly | <p>Consider the following:</p>
<pre><code> def funcA():
some process = dynamicVar
if dynamicVar == 1:
return dynamicVar
else:
print "no dynamicVar"
def main():
outcome = funcA()
</code></pre>
<p>If the 'some process' part results in a 1, the var dynamicVar is passed back as <code>outcome</code> to the main func. If dynamicVar is anything but 1, the routine fails as no arguments are being return. </p>
<p>I could wrap the outcome as a list:</p>
<pre><code> def funcA():
outcomeList = []
some process = dynamicVar
if dynamicVar == 1:
outcomeList.append(dynamicVar)
return outcomeList
else:
print "no dynamicVar"
return outcomeList
def main():
outcome = funcA()
if outcome != []:
do something using dynamicVar
else:
do something else!
</code></pre>
<p>or maybe as a dictionary item. Each of the 2 solutions I can think of involve another set of processing in the main / requesting func. </p>
<p>Is this the 'correct' way to handle this eventuality? or is there a better way? </p>
<p>What is the proper way of dealing with this. I was particularly thinking about trying to catch <code>try:</code> / <code>except:</code> errors, so in that example the uses are reversed, so something along the lines of:</p>
<pre><code> def funcA():
some process = dynamicVar
if dynamicVar == 1:
return
else:
outcome = "no dynamicVar"
return outcome
def main():
try:
funcA()
except:

5,853,220 | 5,853,221 | Should I learn C# or PHP? | <p>I pretty much have been in I.T. for about 10 years. I started with a lot of telecommunications programming and some basic help desk skills. The last job I had before I was laid off in May of last year involved monitoring and testing web applications using HP Mercury tools like BAC, and Mercury Loadrunner. I used to test C++ based scripts making basic quick fixes to the scripts. I really didnt do any test case building or anything just monitoring and testing. I also worked with one of the developers on my team on an application he developed basically keeping it updating it or maybe recreating and relaunching it to people in the company if needed. Anyway I kind of got the programmer bug to go that route. Everything was all about the web there and web applications for customers to use. I have taken an online intro to C++ course and I'm wondering what should be the best language to learn next based on my background to build on what I already know. I live in the San Diego area and I see a lot of C# Java and PHP developer jobs. I'm really trying to decide between C# and PHP. A lot of people say PHP isnt a real progeramming language and all that but recruiters are always asking me about it and suggesting I learn it. On the other side of the coin is the job security thing. Anyway I know I'm a bit long winded here but just wanted to get some advice if I could. </p>

However if this the case, how there exists solutions which can decrypt the files and play them from within the app?
Also as per my R&D, the device should support play-ready file format. Hence now OEM's are launching phones like HTC, nokia with play-ready support. But how will we provide support on apple devices?
