• Using a proxy for NSURLConnection

  - by SideSwipe

  Is there any way to get the content of a webfile (namely a .html Document) using a proxy, which is not defined in the system settings? I know that NSURLConnection is the right way to download a web file into a variable and not into a file (for which we should use NSURLDownload), but I don't find a way to use a proxy for it. Are there some unofficial APIs, Libraries or Classes or such I could use for what I want to do? I'm not that pro in Mac Programming, so I'm searching for something more or less simple. SideSwipe

• Does Django tests run slower on the mac compared to linux?

  - by Thierry Lam

  I'm currently developing my Django projects on both: Mac OS X 10.5, 32 bit Ubuntu Server 9.10 64 bits (1 CPU, 512MB RAM) Both of the above OS are using: Python 2.6.4 Django 1.1.1 MySQL 5.1 Running 12 tests for one of my application take: Mac: 57.513s Linux: 30.935s EDIT: Mac Hardware Spec: MacBook Pro 2.2 GHz Intel Core 2 Duo 3GB RAM I'm running the Ubuntu OS on the same mac above through VMware Fusion 2.0.6. You might argue that Ubuntu Server 64 bits is faster but I have observed a similar speed difference on Ubuntu 8.10 32 bits desktop edition. Even if I turn off my linux VM and other mac applications, I still experience the slowness. Has anyone else experienced this Django test speed difference across those two OS?

• Multiple Producers Single Consumer Queue

  - by Talguy

  I am new to multithreading and have designed a program that receives data from two microcontroller measuring various temperatures (Ambient and Water) and draws the data to the screen. Right now the program is singly threaded and its performance SUCKS A BIG ONE. I get basic design approaches with multithreading but not well enough to create a thread to do a task but what I don't get is how to get threads to perform seperate task and place the data into a shared data pool. I figured that I need to make a queue that has one consumer and multiple producers (would like to use std::queue). I have seen some code on the gtkmm threading docs that show a single Con/Pro queue and they would lock the queue object produce data and signal the sleeping thread that it is finished then the producer would sleep. For what I need would I need to sleep a thread, would there be data conflicts if i didn't sleep any of the threads, and would sleeping a thread cause a data signifcant data delay (I need realtime data to be drawn 30 frames a sec) How would I go about coding such a queue using the gtkmm/glibmm library.

• Getting NoClassDefFoundError only with TestCases

  - by Teja

  I have one class, that creates excel sheet.For that I added poi-3.2.jar to classpath. I am working with Eclipse3.7. I have generated testcases by recording workbench actions using with WindowTester Pro. I edited generated testcase and tried to create excel sheet within that to write test result. If I use same API from normal java program (within that plugin itself), it can able to create excel file without errors. But, when I try to create from testcase, I am getting the following error: java.lang.NoClassDefFoundError: org/apache/poi/hssf/usermodel/HSSFWorkbook I have added required jar file into lib folder and added to build-path. Why its working from normal java program, but not working from WindowTester generated testcase. Could anyone help me.

• PDF Viewer Showing Last Page...

  - by steve

  I have a asp.net app that writes a pdf to file. Then, later that file is opened into a window (standard acrobat reader) for viewing. No problems there. The weird part... The entire document loads as it should, but the Reader initially shows the last page in the document on the screen. The user must then scroll up to the first page. It doesn't happen all the time (about 50%) and occurs across several test computers. Is there a switch in the code I'm suppose to use in creating the file or displaying the file to tell the reader to "start displaying the document on the first page?" Environment particulars: asp.net 3.5 vb, websupergoo's abcpdf.net pro 7 (assembly that creates the pdf file), Windows 2008 Server, IIS7 Thanks

• Efficiency of the .NET garbage collector

  - by Jonas B

  OK here's the deal. There are some people who put their lives in the hands of .NET's garbage collector and some who simply wont trust it. I am one of those who partially trusts it, as long as it's not extremely performance critical (I know I know.. performance critical + .net not the favored combination), in which case I prefer to manually dispose of my objects and resources. What I am asking is if there are any facts as to how efficient or inefficient performance-wise the garbage collector really is? Please don't share any personal opinions or likely-assumptions-based-on-experience, I want unbiased facts. I also don't want any pro/con discussions because it won't answer the question. Thanks

• PHP getting blank pages after submit a form + signal Segmentation fault (11)

  - by Ole Media

  I few days ago I update my macbook pro to snow leopard, and since then some php files are not showing. This is what happens: I created a php form, when going to 'http://localhost/webform.php' I can see the form just fine. Then, once I submit the form, I just get a blank page. I enable error and warnings reporting under php.ini to make sure I'm not missing something, but still I'm not getting anything, just the blank page. Then I checked under apache log files, and what I notice is that every time I submit the form I see the following line coming up under the apache logs: [Wed Apr 07 21:40:28 2010] [notice] child pid 70223 exit signal Segmentation fault (11) I'm clueless on this one. Any ideas on how to fix it?

• Disable IPV6 on specific NIC via PowerShell using a Com Object on Windows Server 2008 R2?

  - by user1256194

  I need to script some Windows Server 2008 R2 builds, preferably in PowerShell. I need to disable or uncheck IPV6 on a specific NIC (the same NIC every time). Currently, I have to set it manually. I do not want to disable IPV6 completely for the entire server other things may use that in the future. Is there an object I can reference in a PowerShell command specifying my NIC "Intel(R) PRO/1000 MT Network Connection" and disable IPV6? Unfortunately, Group Policy is not an option says the boss. I've tried finding an appropriate WMI object via "PowerShell Scriptomatic" but failed to find the difference between an enabled setting versus disabled on the Intel NIC. Thanks in advance.

• Javascript Closure question.

  - by Tony

  Why the following code prints "0-100"? (function () { for ( var i = 100; i >= 0; i -= 5) { (function() { var pos = i; setTimeout(function() { console.log(" pos = " + pos); }, (pos + 1)*10); })(); } })(); I declare pos = i , which should be in a descending order. This code originated from John Resig' fadeIn() function in his book Pro javascript techniques.

• SharePoint 2010 Development on Virtual Machine - Windows 7 or Server 2008?

  - by webworm

  I recently switched to a MacBook Pro for my development machine (for many reasons). I want to setup a Virtual Machine for ASP.NET, IIS, and Visual Studio 2010 development. I also have need to do some development work with SharePoint 2010. What I am wondering is if I should use Windows 7 (64 bit) or Windows Server 2008 (64 bit) as the OS for my development virtual machine. I don't really need most of the services running in Server 2008 so I felt that Windows 7 would probably run faster in the VM environment however I am fairly new to SharePoint 2010 so I am not sure if Windows 7 (64 bit) can be used as a development environment for it. Thanks for any input.

• Firebug is permanently inactive

  - by bwb

  Firebug used to work fine -- until something happened -- not sure what. FF 3.6.3 on XP PRo current. The net effect is Firebug is now always inactive. The icon is present and gray as is normal. Click on the icon and I get: It does this regardless of the site. I've uninstalled Firebug and re-installed. nada. Additionally, the Tools Firebug menu yields nothing. The only unusual issue I can think of is it may of stopped working sometime after I created an additional FF profile (which has since been removed) for a test. Somehow, in removing the extra profile, my bookmarks were deleted. I recovered them from by my online-backup service. Any suggestions? I'd really like to get the Firebug functionality back. thanks.

• Windows 7 - XP Mode - Apache

  - by Howard

  I've setup Virtual PC and XP Mode on my Windows 7 Pro. Using Apache 2.0.52 I have no problems having my website up and running on the Windows 7 machine. But Under VPC/XP Mode the best I can do is Localhost mode. What do I need to do to enable http connections? I need the XP Mode as besides the website I also run a Web BBS and a Dos based (via telnet) BBS. Some of the apps in the Dos BBS just won't work under 64 bit, no matter what setting (capability) are used. Thanks in advance...

• How can I persist a large Perl object for re-use between runs?

  - by Alnitak

  I've got a large XML file, which takes over 40 seconds to parse with XML::Simple. I'd like to be able to cache the resulting parsed object so that on the next run I can just retrieve the parsed object and not reparse the whole file. I've looked at using Data::Dumper but the documentation is a bit lacking on how to store and retrieve its output from disk files. Other classes I've looked at (e.g. Cache::Cache appear designed for storage of many small objects, not a single large one. Can anyone recommend a module designed for this? EDIT. The XML file is ftp://ftp.rfc-editor.org/in-notes/rfc-index.xml On my Mac Pro benchmark figures for reading the entire file with XML::Simple vs Storable are: s/iter test1 test2 test1 47.8 -- -100% test2 0.148 32185% --

• Win XP cannot connect (or see) my wifi network, but can see others

  - by Jorre

  since yesterday I have a strange wifi problem with my pc. I have a wireless linksys router setup that worked fine for many months, now since yesterday my pc won't connect to the wifi signal anymore. The strange thing is, my macbook pro still connects fine. SSID is broadcasting, but my windows XP doens't see it, I have all signal modes set to "auto". Windows XP sees all my neighbours wifi networks, so the wifi card isn't broken or anything. Any idea what can be wrong here?

• Beginner, learning as I go - how to get C#/SQLite db set up and ready for testing?

  - by ChrisC

  I've messed with Access a little bit in the past, had one class on OO theory, and one class on console c++ apps. Now, as a hobby project, I'm undertaking to write an actual app, which will be a database app using System.Data.SQLite and C#. I have the db's table structure planned. I have System.Data.SQLite installed and connected to VS Pro. I entered my tables and columns in VS, but that's where I'm stuck. I really don't know how to finish the db set up so I can start creating queries and testing the db structure. Can someone give me guidance to online resources that will help me learn how to get the db properly set up so I can proceed with testing it? I'm hoping for online resources specific to beginners using C# and System.Data.SQLite, but I'll use the closest I can get. Thanks.

• Flash Displaying Weird Text in a Dynamic Text Field

  - by Andrew M

  I am working in Flash CS5 and I have placed a text field (dynamic, classic text) on the stage. I am accessing it through Actionscript on the same frame like this: var ct:TextField = TextField(getChildByName("Temperature")); ct.text = "Hello world"; What ACTUALLY appears is this: eo wor So... The H, Ls, and D are gone. Mysteriously. Without warning. I am sitting here utterly confused. Is this just me? PS. The text field is set to Myriad Pro Bold, a font on my computer, so it isn't like it's a font problem.

• How to create a new IDA project based on an existing one with different offsets?

  - by tbergelt

  I have an existing IDA Pro project for a C166 processor embedded application. This project already has many functions, variables, etc defined. There are different versions of the embedded application I am looking at. The different versions of the application are 99% the same, but with slight variations in code and data that cause functions and variables to be at different memory offsets. I want to create a new IDA project for a different version of the application. I would like to somehow import all of my function and variable definitions from my existing IDA project. I would like IDA to recognize the signatures of the existing function definitions and define them at there new location in the new project. How can I do this? Are there certain plugins for IDA I can chain together?

• Is this bad style of programming(C#) ?

  - by m0s

  Hi, so in my program I have parts where I use try catch blocks like this try { DirectoryInfo dirInfo = new DirectoryInfo(someString); //I don't know if that directory exists //I don't know if that string is valid path string... it could be anything //Some operations here } catch(Exception iDontCareWhyItFailed) { //Didn't work? great... we will say: somethings wrong, try again/next one } Of course I probably could do checks to see if the string is valid path (regex), then I would check if directory exists, then I could catch various exceptions to see why my routine failed and give more info... But in my program it's not really necessary. Now I just really need to know if this is acceptable, and what would a pro say/think about that. Thanks a lot for attention.

• I don't seem to have an ASPNET user account running on my machine.

  - by pkiyan

  Hi: I'm reading up on ASP.NET, and just came to a chapter that explains how to upload a file to your website. It says that in order to save a file to your file system, in the case of every OS except Win Server '03, an ASP.NET page executes in the security context of the ASPNET account. I don't have an ASPNET account running on my machine (win xp pro sp3; .NET 3.5). The program runs fine, by the way, I'm just trying to understand what an ASPNET account is exactly, and why it doesn't seem to show up on my list of user accounts. Thanks.

• What's the proper way of importing option lists into an Android app?

  - by Scott

  I have been storing option lists for my Android app in a cloud table. For example, categories like "historical fiction","biography","science fiction", etc. I see the following pros and cons: Pro: I can make changes to the list without sending an app update to Google Play Not normalized - I can use the text in my other data tables instead of a reference ID Con: App needs to take time to download from the web each time (or at least check for changes) English only I believe the "proper" way to do this is the use the XML resource files. But I need to make sure the selection references correctly with my data. That is, my app needs to understand that "Poetry" and "Poesía" are the same thing. Is the correct thing to do: Forget about it since I'll never get to the point where I'm translating my app anyway Use a string-array and use the index (0...x) to know what the selection is Use a 2-dimensional string-array with a reference ID in the first column and the text in the second?

• What are some Servlet Container pros and cons for a Solr installation?

  - by danieltalsky

  The SolrInstall wiki page lists seven different server / Servlet Containers compatible with Solr: Tomcat Jetty Resin JBoss WebSphere Weblogic Glassfish I'm sure that "best" is subjective, so I'll just say my criteria are: easiest to set up, best for search performance with a smallish, infrequently-updated dataset, and with the fewest number of gotchas. Jetty and Tomcat both have apt-get solr packages, so they're clearly the frontrunners for some. Jetty is used in the demo install, but there's some notes that Jetty has some difficulties handling Unicode in some cases. Tomcat is a common choice but my understanding is that it's not as lightweight and has a lot of features not needed by Solr. Is it worth considering any of the others? Are there some important pro's and cons I should be aware of?
