• How can I prevent application domain stealing?

  - by dr jerry

  I'm in the process of making a javascript application and I want to bring that online, lets call it mydesign. I'm living in the Netherlands so mydesign.nl can be mine. Now is mydesign.com available for sale by some domain broker sales bastards. And those bastards don't accept a first bid lower than 1000$ which is a about ten times of the budget I'm willing to pay. So far so good, it's a sick business model but it's there. Now lets imagine that mydesign.nl is a huge success in the Netherlands and I'm makin tons of profits out of advertisements and other things I'm not yet aware of (I know entering the lotery gives a better chance of earning money, but lets just imagine). Is there a way (licence, legal or otherwise) to prevent the sick owners of mydesign.com to download and steal my javascript app and deploy it on their own site and take the profits of my app?

• Python json memory bloat

  - by Anoop

  import json import time from itertools import count def keygen(size): for i in count(1): s = str(i) yield '0' * (size - len(s)) + str(s) def jsontest(num): keys = keygen(20) kvjson = json.dumps(dict((keys.next(), '0' * 200) for i in range(num))) kvpairs = json.loads(kvjson) del kvpairs # Not required. Just to check if it makes any difference print 'load completed' jsontest(500000) while 1: time.sleep(1) Linux top indicates that the python process holds ~450Mb of RAM after completion of 'jsontest' function. If the call to 'json.loads' is omitted then this issue is not observed. A gc.collect after this function execution does releases the memory. Looks like the memory is not held in any caches or python's internal memory allocator as explicit call to gc.collect is releasing memory. Is this happening because the threshold for garbage collection (700, 10, 10) was never reached ? I did put some code after jsontest to simulate threshold. But it didn't help.

• tomcat multithreading problem

  - by jutky

  Hi all I'm writing a java application that runs in Tomcat, on a multi-core hardware. The application executes an algorithm and returns the answer to the user. The problem is that even when I run two requests simultaneously, the tomcat process uses at most one CPU core. As far as I understand each request in Tomcat is executed in separate thread, and JVM should run each thread on separate CPU core. What could be the problem that bounds the JVM or Tomcat to use no more than one core? Thanks in advance.

• Custom annotations to configure tests

  - by ace

  First of al let me start off by saying I think custom annotations can be used for this but i'm not totally sure. I would like to have a set of annotations that I can decorate some test classes with. The annotations would allow me to configure the test for different environments. Example: public class Atest extends BaseTest{ private String env; @Login(environment=env) public void testLogin(){ //do something } @SignUp(environment=env) public void testSignUp(){ //do something } } The idea here would be that the login annotation would then be used to lookup the username and password to be used in the testLogin method for testing a login process for a particular environment. So my question(s) is this possible to do with annotations? If so I have not been able to find a decent howto online to do something like this. Everything out there seems to be your basic here's how to do your custom annotations and a basic processor but I haven't found anything for a situation like this. Ideas?

• Is the method addSubview of NSView inherently slow? (Cocoa OSX)

  - by Michael Minerva

  I am trying to speed my gui that loads very slow slow when I am loading a large project (the gui is a representation of groups and sub groups and is made up of many views). During this process I was looking at how long certain code segments take to execute and I have found that a call to addsubview is taking between 10 and 20 milliseconds most of the time. The subview I was looking at is a disclosure button. I am wondering if this method is just inherently slow or is their some other factor at work here? Is the time it takes to add the subview dependent on the complexity of the subview or is that not a factor? Also, is there some other method that can be used to add a subview that might be faster?

• For simple C cmd programs: how to add "program executed in 12,345 seconds" ?

  - by WoodsieLord

  I'm a windows user, and I'm learning C. I use Codeblocks and visual c++ 2008 express at home to write simple C command line programs (I'm a beginner) and I find really useful when codeblocks adds a few lines at the end with the time it takes (example: "Process returned 0 (0x0) execution time : 6.848 s"). I want to add this functionality to the .exe so I can 'benchmark' or 'test' the program on a few computers. I tried using time(NULL) but it only works with 1 second precision. I also found very interesting answers here (I'm actually looking for the same thing): http://stackoverflow.com/questions/2173323/calculating-time-by-the-c-code The solution proposed by Mark Wilkins, works fine on visual c++ 2008 express on my windows 64 bit PC, but the .exe does not work anywhere else. Am I doing something wrong? I would like a method to count elapsed wall time for my programs, that must have 32bit compatibility. Thanks in advance!

• binding plugin to ajax call

  - by zurna

  I take categories from another page with an ajax call. The problem is, data taken from another page needs to be part of another of an event; tabs plugin. I get the following error with this code. $.ajax({ dataType: "xml", success: function(xml) { $(xml).find('row').each(function(){ var id = $(this).attr('id'); var CategoryName = $(this).find('CategoryName'); $("<div class='tab fleft'><a href='http://www.refinethetaste.com/FLPM/content/home/index.cs.asp?Process=ViewVideos&CATEGORYID="+ id +"'>"+ CategoryName.text() + "</a></div>").appendTo("#VCategories"); }); } }).live('click', function() { $("div.row-title").tabs("div.redpanes > div"); });

• OS X Dock API? Retrieve OS X active application's icon with badges and other modifications.

  - by pokstad

  Is there an API for retrieving the icons of the currently open apps on Mac OS X? I am trying to retrieve all the icons of the active applications along with any badges on top of the application (i.e. number of new messages in mail, or current download rate in Transmission). Is there some sort of Dock API? The only mention of an OSX API for retrieving information about currently active applications I have been able to find is the Process Manager API, which does not mention the ability to poll the dock or retrieve icon data.

• How to implement thread timeout in J2ME?

  - by lilo

  I am using Connector in J2ME and found that sometimes it take a very long time to send a request, and sometime it may halt the whole process. So I try to put code related to Connector in a thread and try to set timeout to the thread. But I found out that it's very difficult to do this in J2ME because there's no join(long) in J2ME. Is there any way to do this? Or any better way to deal with network connection in J2ME? Thanks a lot in advance.

• Javascript Prototype Best Practice Event Handlers

  - by nahum

  Hi this question is more a consulting of best practice, Sometimes when I'm building a complete ajax application I usually add elements dynamically for example. When you'r adding a list of items, I do something like: var template = new Template("<li id='list#{id}'>#{value}</li>"); var arrayTemplate = []; arrayOfItem.each(function(item, index){ arrayTemplate.push(template.evaluate( id : index, value : item)) }); after this two options add the list via "update" or "insert" ----- $("elementToUpdate").update("<ul>" + arrayTemplate.join("") + "</ul">); the question is how can I add the event handler without repeat the process of read the array, this is because if you try add a Event before the update or insert you will get an Error because the element isn't still on the DOM. so what I'm doing by now is after insert or update: arrayOfItem.each(function(item, index){ $("list" + index).observe("click", function(){ alert("I see the world"); }) }); so the question is exist a better way to doing this??????

• Error HRESULT E_FAIL when creating Exchange mailbox (CDOEXM.IMailboxStore.CreateMailbox)

  - by Matt

  I am trying to automate the process of creating an Exchange Mailbox for AD users and am running into an issue. When calling the CreateMailbox method I am receiving the error "Error HRESULT E_FAIL has been returned from a call to a COM component". I have installed and referenced the Exchange Management Tools and am using impersonation for permissions. Here is the code: ActiveDs.IADsUser adUser = (ActiveDs.IADsUser)user.NativeObject; adUser.AccountDisabled = !Active; user.CommitChanges(); //Set Password user.Invoke("SetPassword", Password); user.CommitChanges(); //Create Mailbox IMailboxStore mailbox; mailbox = (IMailboxStore)adUser; mailbox.CreateMailbox("LDAP://CN=StandardUsers,CN=StandardUsers,CN=InformationStore,CN=xxxxx," + "CN=Servers,CN=First Administrative Group,CN=Administrative Groups," + "CN=xxxxx Main,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=xxxxx,DC=com"); user.CommitChanges();

• How can I enforce Eclipse to use Sun Java?

  - by Dan

  Hi Before installing Eclipse I had Open JDK on default. Now I changed it to Sun Java. I did as Eclipse Helios was running really slow, unfortunately it is still... Do you have any ideas how to enforce it to use Java Sun? I could reinstal it however I have already Android SDK installed so I would have to do all the process again, after all thats not the correct way of solving problem I think. I'm using Ubuntu 10.10. java -version java version "1.6.0_22" Java(TM) SE Runtime Environment (build1.6.0_22-b04) Java HotSpot(TM) 64-Bit Server VM (build 17.1-b03, mixed mode) Would be grateful for any help. Best, Daniel

• How to make Mac OS X CrashReporter invoke debugger?

  - by StasM

  I have an appache module on Mac OS X that produces random crashes. I can reproduce these crashes with certain sequence of actions, and these crashes produce Crash Reporter dialog "httpd quit unexpectedly". Is there a way to cause Crash Reporter launch debugger (xcode, gdb, anything) instead of just displaying the backtrace? I've tried running httpd under gdb with httpd -X but the crash doesn't happen then - it happens only if many httpd's are running at once, and I found no way to attach gdb to all of them at once. So I was hoping maybe I can cause CrashReporter to attach the debugger when specific process crashes - is there a way to do it?

• How to handle lifecycle of dynamically allocated data in Windows messages?

  - by nang

  Simple task: Send a windows message with dynamically allocated data, e.g. an arbitrary length string. How would you manage the responsibility to free this data? The receiver(s) of the windows message could be responsible to free this data. But: How can you guarantee that all messages will actually be received and thus the linked data will be freed? Imagine the situation that the receiver is shutting down, so it won't process it's message queue any more. However, the message queue still exists (for some time) and can still accept messages, which won't be processed any more. Thanks!

• PHP Looping....need some advice

  - by Homer_J

  Hi all, I have the following code: $q1 = $_POST["q1"]; $q2 = $_POST["q2"]; $q3 = $_POST["q3"]; $q4 = $_POST["q4"]; $q5 = $_POST["q5"]; $q6 = $_POST["q6"]; $q7 = $_POST["q7"]; $q8 = $_POST["q8"]; At the moment, this is hard coded and I need to manually change it each time, I'd like to use variables instead so that it's not a manual process. Is it a case of using a loop, while or foreach? If I had the the information $q and q in an array would that help? Thanks, Homer.

• Preallocate memory for a program in Linux before it gets started

  - by Fyg

  Hi, folks, I have a program that repeatedly solves large systems of linear equations using cholesky decomposition. Characterising is that I sometimes need to store the complete factorisation which can exceed about 20 GB of memory. The factorisation happens inside a library that I call. Furthermore, this matrix and the resulting factorisation changes quite frequently and as such the memory requirements as well. I am not the only person to use this compute-node. Therefore, is there a way to start the program under Linux and preallocate free memory for the process? Something like: $: prealloc -m 25G ./program

• Preprocess strings file during Xcode build

  - by stigi

  Hello, I know there's a way to preprocess my info.plist file, but is there a similar way to process strings files inside my Settings.bundle? My problem: I have an iPhone app and I want the the user to know about the currently installed version. I do this by displaying it in the apps settings. Now every time i change the bundle version in my info.plist i also have to change the version in the Root.strings in the Settings.bundle. I could run a script action that updates it, but it would be nice to use the preprocessor since I could do even more fun things with it. Thanks!

• Run exe on computer in network through batch file

  - by Peter Kottas

  I have few computers connected to the network and I want to create batch files to automatize the process of working with them. I have already created one used to shutdown computers at once. It is very simple I ll just post it for the sake of argument. @echo off shutdown -s -m \\Slave1-PC shutdown -s -m \\Slave2-PC shutdown -s -m \\Slave3-PC Now I want to execute programs on these machines. So lets say there is "example.exe" file located "\Slave1-PC\d\example.exe" using call \\Slave1-PC\\d\\example.exe runs it on my computer through network and i didn't come up with anything else. I dont want to use any psexec if possible. Help would be much appreciated. Peter

• Strange behavior of for loop in scheduler_tick

  - by EpsilonVector

  I'm working on Linux kernel 2.4 (homework) and I inserted the following code into the scheduler_tick function: if (unlikely(rt_task(p)) || (p->policy==SCHED_PROD && p->time_ran>=p->process_expected_time)) { /* * RR tasks need a special form of timeslice management. * FIFO tasks have no timeslices. */ if ((p->policy == SCHED_RR || /*change*/p->policy==SCHED_PROD) && !--p->time_slice) { /*changes*/ if (p->policy == SCHED_PROD){ for (i=0; i<5000; i++){ printk("I'm leeching off SCHED_RR code! %d\n", i); } } /*end changes*/ The addition was added for debugging purposes. For some reason this causes very weird behavior: when a SCHED_PROD process triggers this code (and consequently the loop that follows) the loop counts to about 4600 normally, but then goes back to 4600 each time it counts to 4800, and gets stuck in an infinite loop. What's going on?? EDIT: The i variable is my own.

• Sending mail via sendmail from python

  - by Nate

  If I want to send mail not via SMTP, but rather via sendmail, is there a library for python that encapsulates this process? Better yet, is there a good library that abstracts the whole 'sendmail -versus- smtp' choice? I'll be running this script on a bunch of unix hosts, only some of which are listening on localhost:25; a few of these are part of embedded systems and can't be set up to accept SMTP. As part of Good Practice, I'd really like to have the library take care of header injection vulnerabilities itself -- so just dumping a string to popen('/usr/bin/sendmail', 'w') is a little closer to the metal than I'd like. If the answer is 'go write a library,' so be it ;-)

• saving values of editText in replaced fragment

  - by Eppo

  I have a 2 fragment layout, on the left fragment, i have a list of the different table names, on the right, i open up a different table depending on what is clicked on the right fragment. my intention, is that the first list item is clicked, then values will be entered on the table, next the second list item is clicked, the next table opens up and those values are entered. what would be the best way to store the values of the results entered in the editboxes, so i can process them all at once? I'm sure i can use onPause to save them all, but would that be the best way? Thanks

• Browser application & local file system access

  - by Beyond HTML

  I want to enhance my browser-based web application with functionality that enables management of local files and folders. E.g. folder tree structures should be synchronized between local workstation and server via HTTP(S). I am aware of security-related limitations in browser-based applications. However, there are some techniques that "work around" these issues: Signed Java applets (full trust) .NET Windows Forms browser controls (no joke, that works. Just the configuration is horrible) ActiveX My question is: What do you use/suggest, both technology and implementation practice? Key requirement is that the installation process is as simple as possible. Thanks for your opinions!

• How to read tags out of m4a files in .NET?

  - by dkackman

  I've got some heavily modified code that ultimately came from the Windows Media SDK that works great for reading tags out of MP3 and WMV files. Somewhere along the line, Windows Media Player added support for .m4a files (was it in Windows 7?) but the Windows Media API doesn't seem to reflect that addition (or at least IWMMetadataEditor2::OpenEx pukes on an .m4a file). What would be some good C# code or links on how to dig meta data tags out of m4a files? (Google has come up dry on the C# front.) UPDATE AtomicParsley did indeed end being the best approach. Since that code is a command line tool however I ended up having to create a managed wrapper around some of its functionality in order to use in-process. It is posted on google code if anyone else needs such a thing.

• How to apply patterns when not all team members can follow them

  - by michael moore

  We're going to start a new huge project and while it's in the process of architecting the system, I have certain doubts whether I can apply patterns and be sure they won't be violated by team members. The problem is, not all team members have enough skills to develop asp.net apps let's say using MVP pattern. So maybe this question is addressed to Team leads, or experienced devs. Did you dealt with this kind of situation, and if so what was your solution. I was thinking to create the core by myself, and let 'em start building upon that core, however I'm not sure it will work out.
