• Making DiveIntoPython3 work in IE8 (fixing a Javascript performance issue)

  - by srid

  I am trying to fix the performance problem with Dive Into Python 3 on IE8. Visit this page in IE8 and, after a few moments, you will see the following popup: I traced down the culprit down to this line in j/dip3.js ... find("tr:nth-child(" + (i+1) + ") td:nth-child(2)"); If I disable it (and return from the function immediately), the "Stop executing this script?" dialog does not appear as the page now loads fairly fast. I am no Javascript/jquery expert, so I ask you fellow developers as to why this query is making IE slow. Is there a fix for it? Edit: you can download the entire webpage (980K) for local viewing/editing.

• What are some fun project ideas for a new Python developer?

  - by Sergio Tapia

  I'm new to Python 3 and so far it seems like a decent language. I really like the string manipulation methods you can use and they are pretty radical. :) I'm stuck however in thinking of a project to do with Python. Is there a site similar to Coding4Fun but for Python? Community Wiki because I think this question is really interesting. :D

• Very slow Eclipse 4.2, how to make it more responsive?

  - by Laurent

  I'm using Eclipse PDT on a rather large PHP project and the IDE is almost unusable. It takes nearly 30 seconds to open a file, and other actions, like selecting a folder in the file explorer, editing some text, etc. are equally slow. I followed various instructions to speed it up but nothing seems to work. This is my current eclipse.ini file. Any idea how I can improve it? -startup plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar --launcher.library plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.200.v20120522-1813 -showsplash org.eclipse.platform --launcher.XXMaxPermSize 256m --launcher.defaultAction openFile -vmargs -server -Dosgi.requiredJavaVersion=1.7 -Xmn128m -Xms1024m -Xmx1024m -Xss2m -XX:PermSize=128m -XX:MaxPermSize=128m -XX:+UseParallelGC System: Eclipse 4.2.0, Windows 7, 4 GB RAM

• Does Scheme work with Microsoft COM?

  - by Martin

  I'm new to Scheme -- the functional programming language and I like it a lot for its first-class/higher-order functions. However, my data comes from a COM source with an object-oriented API. I know Scheme and COM belong to different programming paradigms, but I'm wondering if there is any interface or a way for Scheme to connect to a COM source? Thanks.

• insertNewObjectForEntityForName:inManagedObjectContext: returning NSNumber bug?

  - by beinstein

  I'm relatively well versed in CoreData and have been using it for several years with little or no difficulty. For the life of me, I can't figure out why insertNewObjectForEntityForName:inManagedObjectContext: is all of a sudden returning some sort of strange instance of NSNumber. GDB says the returned object is of the correct custom subclass of NSManagedObject, but when I go to print a description of the NSManagedObject itself, I get the following error: *** -[NSCFNumber objectID]: unrecognized selector sent to instance 0x3f26f50 What's even stranger, is that I'm able to set some relationships and attributes using setValue:forKey: and all is good. But when I try to set one specific relationship, I get this error: *** -[NSCFNumber entity]: unrecognized selector sent to instance 0x3f26f50 I've tried everything from clean all targets, to restarting both mac and iPhone, even editing the model so that the relationship in question is to-one instead of to-many. No matter what I do, the same problem appears. Has anyone ever seen anything like this before?

• C precision of double: compiler dependent?

  - by yCalleecharan

  Hi,on my 32-bit machine (with an Intel T7700 duo core), I have 15 precision digits for both double and long double types for the C language. I compared the parameters LDBL_DIG for long doubles and DBL_DIG for doubles and they are both 15. I got these answers using MVS2008. I was wondering if these results can be compiler dependent or do they just depend on my processor? Thanks a lot...

• HTML Types - Learning Order?

  - by Gabe

  I've decided that today - as soon as this question is answered, in fact - I'm going to dive into learning HTML. But, looking online, I've noticed there are many types: HTML, XHTML, HTML5, and so on. So, which should I start with? In what order should I learn them? And, for that first language, where should I learn at?

• Any editors to visually modify Wix templates?

  - by user1632018

  I have tried wixedit and sharp develop and from what I can tell they do not allow you to visually modify the premade templates with a designer. They only allow you to create your own customized dialogs that you can design yourself. So I am wondering if there is any editors that you can visually modify the design of these templates, especially the mondo template with a point and click editor. I have also tried SharpSetup and it looks promising how you can design the interface in visual studio, although since I don't know much about editing wix I am having a hard time comming up with the wix code to make it work.

• C++ Win32 API equivalent of CultureInfo.TwoLetterISOLanguageName

  - by Brian Gillespie

  The .NET framework makes it easy to get information about various locales; the Win32 C++ APIs are a bit harder to figure out. Is there an equivalent function in Win32 to get the two-letter ISO language name given an integer locale ID? In C# I'd do: System.Globalization.CultureInfo ci = new System.Globalization.CultureInfo(1034); string iso = ci.TwoLetterISOLanguageName; // iso == "es" now.

• Why has anybody ever used COBOL?

  - by sarzl

  I know: You and me hate COBOL. I took a look at a lot of code examples and it didn't take me long to know why everybody tries to avoid it. So I really have no idea: Why was COBOL ever used? I mean: Hey - there was Fortran before it, and Fortran looks like a jesus-language compared to COBOL. This isn't argumentative but historical as I'm young and didn't even know about COBOL before 4 months.

• Unable to ping server from client B but able to ping from client A. Please help

  - by Soundar Rajan

  This is not really a programming question, but I am at my wit's end ... I am trying to configure a IIS 6.0/Windows Server 2003 web server with a ASP.net application. When I try to ping the server from client computer A I get the following: PING 74.208.192.xxx ==> Ping fails PING 74.208.192.xxx:80 ==> Ping succeeds! From client computer B, BOTH the pings fail. PING 74.208.192.xxx ==> Ping fails PING 74.208.192.xxx:80 ==> Ping fails with a message "Ping request could not find host 74.208.192.xxx:80" Both clients A and B are on the same subnet. The server is outside (a virtual server hosted by an ISP) I have an ASP.NET application in a virtual directory on the server. In IE or firefox, if I enter http://74.208.192.xxx/subdir/subdir/../Default.aspx, it works from both the clients! The server has default firewall settings but web server enabled (Port 80 is open).

• Custom control in DataViewGrid

  - by Winston

  I'm trying to embed a custom control in a Datagridview. I've looked at the Calendar (http://msdn.microsoft.com/en-us/library/7tas5c80.aspx) example but i just cant get it working for a custom control. I need the control to show for each object in the grid. Not just when the user edits the content. I need to do this so that i can bind my dataviewgrid to a datasource and have it create the required forms in the grid for each my object list. So that the user can do inline editing in the grid without having to double click the row and have a new dialog pop up. Any help would be greatly appreciated.

• Portion of Screen Broke

  - by Devoted

  Hi, A portion of my laptop screen broke. Is there any kind of software that will just ignore that part and resize everything accordingly? It's like 1/6 of the screen on the right that makes anything over there impossible to see. If not, what would be the best programming language to go about making my own program? It is a PC but I can also run Ubuntu if that would be easier to make a program for.
