• What's happening between onResume and the activity is really displayed?

  - by Johnny

  I didn't nothing in the onResume of my Activity, but it still takes about 5 seconds between the onResume is called and the activity is really displayed. What's happening under there? Here is the code snip: onResume: @Override protected void onResume() { Log.d(TAG, "on resume >>>"); super.onResume(); } logcat: 05-28 10:36:05.621 D/LoginDialogActivity( 447): on resume >>> 05-28 10:36:06.231 I/ARMAssembler( 52): generated scanline__00000077:03010104_00000004_00000000 [ 22 ipp] (41 ins) at [0x3e3358:0x3e33fc] in 5646001 ns 05-28 10:36:10.690 I/ActivityManager( 52): Displayed activity com.aimi.appstore/.ui.activity.LoginDialogActivity: 5169 ms (total 5331 ms) AndroidManifest.xml: <activity android:name=".ui.activity.LoginDialogActivity" android:theme="@android:style/Theme.Dialog" />

• Adding classes to all form widgets in symfony

  - by rlahay

  Hi everyone, I am trying to find a better way to assign classes to form elements in symfony. Currently, I can't seem to get away from assigning each one manually. ie: $this->widgetSchema['title']->setAttribute("class","fieldInput"); $this->widgetSchema['tag_line']->setAttribute("class","fieldInput"); $this->widgetSchema['description']->setAttribute("class","fieldInput"); // etc Things I tried without success 1) looping through $this-widgetSchema, treating it as an array and setting attributes to each key 2) $this-widgetSchema-setAttribute() but this only applied the class to the label that was generated, not the form element There must be a way to hit all the fields without specifically directing them? Can anyone point me in the right direction?

• Setting Grouping in UITableView under UINavigationController

  - by climbon

  In my UINavigationController app, my first view is a UITableView. I can't seem to find a way to set the property of this UITableView to 'grouped'. Since UITableView is dynamically generated I don't have the luxury of Interface Builder. Searched forums here and googled other places and closest I saw was to override either initWithStyle or initWithCoder as follows. (id)initWithStyle:(UITableViewStyle)style { if (self = [super initWithStyle:UITableViewStyleGrouped]) { } return self; } However this above function never gets called. when I overrided initWithCoder I could see it worked and I was able to change UITableView contents to grouped. But then title automatically became 'Root View Controller' and none of the cells were active anymore although they got grouped fine. That is while they looked active but if you click on them, those cells won't do anything. But I have seen apps which have their very first view being UITableView is grouped. So there must be a way to do it but I don't know how.

• Are there any reasons for why you would include JavaScript using document.writeln

  - by David Johnstone

  Are there any good reasons for why you would include JavaScript like this: <script type="text/javascript">document.writeln('<script src="http://example.com/javascript/MyJavaScript.js" type="text/javascript"><' + '/script>');</script> (Sorry for the long scrolling line. This is in the head of a HTML document.) I've been looking at some HTML recently and I've noticed this a few times (all on the one site). I can't think of any reasons why you would do it like this, but I can hardly claim to be a web developer. It's likely that these lines of code are automatically generated, but still, someone somewhere must have thought this was a good idea.

  Previously, I have no problem in running the JAR file generated by NetBeans. However, I encountered the problem now all of a sudden. When I click on the jar, it did not launch the application as if nothing is clocked. But, it can be run from the project. And also, the size of the Jframe for desktop Java application cannot be set from the NetBeans code also. When it runs, the size of the window different from in the designer. Any help please.

• Using javascript to call controller methond in mvc

  - by Christian Thoresson Dahl

  Im trying to make a table row work as a link to another view in my mvc website. Instead of using the standard "Details" link provided by the auto generated table list, I would like to use the table row as a link to the "Details" view instead. So somehow I need to make the row work as a link. Each rom has a unique id that I need to pass on to the controller method. I have tried different solutions but noting happens when I press on the table row... So far this is what I have: <script type="text/javascript"> $(document).ready(function(){ $('#customers tr').click(function () { var id = $(this).attr('id'); $.ajax({ url: "Customer/Details" + id, succes: function () { } }); }) }) </script> My controller method: public ActionResult Details(int id) { Customer model = new Customer(); model = this.dbEntities.Customers.Where(c => c.Customer_ID == id).Single(); return View(model); }

• LDAP in medium trust

  - by eych

  I've have a solution with one website and several projects. The projects all have the AllowPartiallyTrustedCallers attribute and are strongly-named. The site works in full trust. However, after set the trust to medium, I get the System.Security.SecurityException: Request failed. error as soon as I browse to the site. In my projects, I have calls to LogOnUser, as well as many calls to variousSystem.DirectoryServices.AccountManagement methods. Can this site run with medium trust or do I have to have full trust for all the LDAP calls? As I mentioned, I've set the AllowPartiallyTrustedCallers attribute on all projects. Not sure what else to do. Also, I have no idea what/where the error is being generated. The event logs on the server have nothing in regards to this SecurityException. Is there any way to find out what the error location is so maybe I can attempt to rewrite some code? [running .NET 4.0 on Win2k8R2]

• Implement a simple class in your favorite language.

  - by Oscar Reyes

  I'm doing this to learn syntax of different programming languages. So, how would you defined the following class along with with it's operations in your favorite programming language? Image generated by http://yuml.me/ And a main method or equivalent to invoke it: For instance, for Java it would be: ... public static void main( String [] args ) { Fraction f = new Fraction(); f.numerator( 2 ); f.denominator( 5 ); f.print(); } ....

• [Java] Implement a RSA algorithm

  - by Robin Monjo

  Hello everyone. I want to implement a RSA algorithm to encrypt an image (byte[]). To generate my two keys I used this piece of code : KeyPairGenerator keygen = KeyPairGenerator.getInstance("RSA"); keygen.initialize(512); keyPair = keygen.generateKeyPair(); Once public and private key are generated, I would like to show them to the user so he can distribute the public key and use the private key to decode. How can I get back those key ? Using keygen.getPrivateKey() and keygen.getPublicKey() give me all the information of the RSA algorithm, not only the keys I need. Thanks

• Maximizing the number of threads to fully utilize all available resources without hindering overall

  - by Matt

  Let's say I have to generate a bunch of result files, and I want to make it as fast as possible. Each result file is generated independently of any other result file; in fact, one could say that each result file is agnostic to every other result file. The resources used to generate each result file is also unique to each. How can I dynamically decide the optimal number of threads to run simultaneously in order to minimize the overall run time? Is my only option to write my own thread manager that watches performance counters and adjust accordingly or does there exists some solid classes that already accomplish this?

• Optimal Sharing of heavy computation job using Snow and/or multicore

  - by James

  Hi, I have the following problem. First my environment, I have two 24-CPU servers to work with and one big job (resampling a large dataset) to share among them. I've setup multicore and (a socket) Snow cluster on each. As a high-level interface I'm using foreach. What is the optimal sharing of the job? Should I setup a Snow cluster using CPUs from both machines and split the job that way (i.e. use doSNOW for the foreach loop). Or should I use the two servers separately and use multicore on each server (i.e. split the job in two chunks, run them on each server and then stich it back together). Basically what is an easy way to: 1. Keep communication between servers down (since this is probably the slowest bit). 2. Ensure that the random numbers generated in the servers are not highly correlated.

• SHA-256 encryption wrong result in Android

  - by user642966

  I am trying to encrypt 12345 using 1111 as salt using SHA-256 encoding and the answer I get is: 010def5ed854d162aa19309479f3ca44dc7563232ff072d1c87bd85943d0e930 which is not same as the value returned by this site: http://hash.online-convert.com/sha256-generator Here's the code snippet: public String getHashValue(String entity, String salt){ byte[] hashValue = null; try { MessageDigest digest = MessageDigest.getInstance("SHA-256"); digest.update(entity.getBytes("UTF-8")); digest.update(salt.getBytes("UTF-8")); hashValue = digest.digest(); } catch (NoSuchAlgorithmException e) { Log.i(TAG, "Exception "+e.getMessage()); } catch (UnsupportedEncodingException e) { // TODO Auto-generated catch block e.printStackTrace(); } return BasicUtil.byteArrayToHexString(hashValue); } I have verified my printing method with a sample from SO and result is fine. Can someone tell me what's wrong here? And just to clarify - when I encrypt same value & salt in iOS code, the returned value is same as the value given by the converting site.

• Database for Importing NUnit results?

  - by McWafflestix

  I have a large set of NUnit tests; I need to import the results from a given run into a database, then characterize the set of results and present them to the users (email for test failures, web presentation for examining results). I need to be tracking multiple runs over time, as well (for reporting failure rates over time, etc.). The XML will be the XML generated by nunit-console. I would like to import the XML with a minimum of fuss into some database that can then be used to persist and present results. We will have a number of custom categories that we will need to be able to sort across, as well. Does anyone know of a database schema that can handle importing this type of data that can be customized to our individual needs? This type of problem seems like it should be common, and so a common solution should exist for it, but I can't seem to find one. If anyone has implemented such a solution before, advice would be appreciated as well.

• Running ASP.NET MVC application behind a proxy with different root relative path

  - by Wiebe

  Hi All, I'm having trouble with paths in a ASP.NET MVC application that's running behind a proxy. Our IIS Application root path is for example http://server/MyApp/ meaning that all urls using the application root ("~/",Url.Action("MyAction","MyController")) are resolved to "/MyApp" Now we're running behind a proxy server that forwards all requests, but changes the application root to something like this: "/Secury/Proxy/RubbishUrl/MyApp" Because the original url is only available on the client, I thought of creating a cookie with the path prefix, and insert this before each generated URL on the server. Now the question is, what's the best location in code to modify each URL that's resolved/sent to the client (to resources, controller actions, images etc)? Every path in the application is resolved with the MVC methods (Url.Content, Url.Action etc).

• Newlines not being interpreted when passed to php via the command line

  - by CarbonX

  I have a PHP script that I'm invoking from another shell script that sends an automated email with a message generated from the shell script. Problem is, when I send the message all the newline characters are printed into the message. How do I get them to be interpreted? sendmail.sh: /path/to/phpscript/sendmail.php "Some Message With Newlines\nHello World.\n" sendmail.php: $message = $argv[1] . "\nNewline"; $smtp->send($to, $from, $message); The odd thing is the \n after the $argv variable is interpreted and actually prints Newline on a new line, but the newlines in the $argv variable don't, I have tried wrapping the variable in double quotes among other things but so far to no avail.

• Draw a Image on FullScreen mode Android

This is my XML layout. <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <ImageView android:id="@+id/image01" android:layout_width="fill_parent" android:layout_height="fill_parent" /> </LinearLayout> This image is dynamic generated and drawed in the ImageView. This is my code on my Activity. public void onCreate(Bundle savedInstance) { super.onCreate(savedInstance); requestWindowFeature(Window.FEATURE_NO_TITLE); getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); setContentView(R.layout.main); } But when running, the Activity is FullScreen, but the ImageView is adjusted in the center. What's wrong?

• What is the simplest method to fill the area under a geom_freqpoly line?

  - by mattrepl

  The x-axis is time broken up into time intervals. There is an interval column in the data frame that specifies the time for each row. The column is a factor, where each interval is a different factor level. Plotting a histogram or line using geom_histogram and geom_freqpoly works great, but I'd like to have a line, like that provided by geom_freqpoly, with the area filled. Currently I'm using geom_freqpoly like this: ggplot(quake.data, aes(interval, fill=tweet.type)) + geom_freqpoly(aes(group = tweet.type, colour = tweet.type)) + opts(axis.text.x=theme_text(angle=-60, hjust=0, size = 6)) I would prefer to have a filled area, such as provided by geom_density, but without smoothing the line: UPDATE: The geom_area has been suggested, is there any way to use a ggplot2-generated statistic, such as ..count.., for the geom_area's y-values? Or, does the count aggregation need to occur prior to using ggplot2?

• ProGuard breaks Java application - no text, no images

  - by jocull

  I'm trying to use ProGuard to obfuscate a Java application. I'm experiencing a problem where all of my text and images disappear from the GUI (Swing) forms. I've tried disabling optimizations and including more libraries, but nothing seems to be working. I've inspected the output generated by the obfuscator with a decompiler, and my resource paths seem to still be correct. Do I need to be including more core Java libraries outside of jre/lib/rt.jar? Are there more settings I should disable? ...other suggestions? Thanks.

• Triangular bounding volumes

  - by Cheery

  I've come up with an alternative for beziers that might be easier to ray-trace, perhaps even though a plain vertex shader. Though there's missing a piece. I need to find the parametric surface equation from the surface normals I have for edge vertices. I also have to know it's peak and valley so I can constraint the depth of my bounding triangle. Image explains the overall idea: I build a bounding-volume from a control triangle. Then apply a function to each parametric coordinate of the triangle (s+t+u=1 where s,t,u = 0) to get the height coordinate for that certain point. Simply put, it produces a procedurally generated height-map for the triangle's surface. I just need to find a function that generates the height-map so I can make it work.

• How can I compare Core Data models?

  - by Don

  I noticed while doing system testing that a feature of our app had been removed. It looks like at some point, an older version of a file was checked into SVN that was missing a property. This specific file was generated from the Core Data model, and sure enough, the latest version of the model in SVN is missing the same attribute. I need to find out if any other attributes are missing, or if anything else in the model changed. However, the elements file in the .xcodedatamodel folder appears to binary and I can't compare the revisions. Is there a way to find the differences between two Core Data models in SVN? Barring that, what would be the best way to accomplish this task?
