• Create a playlist in iTunes based on a hard drive folder

  - by Electrons_Ahoy

  I'd like to be able to base playlists in iTunes on a folder on my hard drive. For example, say I have this directory structure: C:\MP3s\Doctor Who Music C:\MP3s\Star Wars Music Importing all those MP3s into iTunes is really simple - at the bare bones version you can just drag the MP3 folder into the iTunes window and it does the rest. But, having done that, what I'd like to be able to do is point iTunes at each of those directories and have it turn them into their own playlists, so I end up with a Doctor Who Music and a Star Wars Music playlist based on the MP3s locations on the hard drive. Does iTunes have a way to do this, or is there a way to trick it into this with some other program? (I'm on Windows, but I'm sure Mac users would also appreciate answers to this as well.)

• How do you unit test JEE code?

  - by marabol

  I want to ask for your prefered way to test JEE code? I found only three project, that are trying to help to code unit tests in JEE environment: http://jakarta.apache.org/cactus/ : Last Published: 2009-01-18 http://www.junitee.org/ : Last Release: 2004-12-11 http://ejb3unit.sourceforge.net/ : Last Release: 2008-05-17 So I wonder, is there any framework helping to write (j) unit test for JEE code? do you use embedded JEE servers like jboss or glassfish v3? do you mockup and inject by yourself? Thanks a lot...

• Python - do big doc strings waste memory?

  - by orokusaki

  I understand that in Python a string is simply an expression and a string by itself would be garbage collected immediately upon return of control to a code's caller, but... Large class/method doc strings in your code: do they waste memory by building the string objects up? Module level doc strings: are they stored infinitely by the interpreter? Does this even matter? My only concern came from the idea that if I'm using a large framework like Django, or multiple large open source libraries, they tend to be very well documented with potentially multiple megabytes of text. In these cases are the doc strings loaded into memory for code that's used along the way, and then kept there, or is it collected immediately like normal strings?

• IE8 AJAX GET setRequestHeaders not working unless params provided in URL

  - by bobthabuilda

  I'm trying to create an AJAX request in IE8. var xhr = new ActiveXObject( 'Msxml2.XMLHTTP' ); xhr.open( 'GET', '/ajax/' ); // Required header for Django to detect AJAX request xhr.setRequestHeader( 'X-Requested-With', 'XMLHttpRequest' ); xhr.onreadystatechange = function() { if ( this.readyState == 4 ) console.log(this.responseText); } xhr.send( null ); This works perfectly fine in Firefox, Chrome, Safari. In IE8 however, all of my AJAX test requests work EXCEPT for ones where I'm performing GETs without any query string params (such as the one above). POSTs work without question, and GET requests only work whenever I include query strings in the URL, like this: xhr.open( 'GET', '/ajax/?foo=bar' ) I'm also 110% positive that my server code is handling these requests appropriately, so, this stumps me completely. Does anyone have any clue as to what might be causing this?

• A look into serialPort

  - by MarekK

  You wrote at: Opened SerialPort crashes C# application "A look into the .NET Framework source code helped a lot. But I think the thrown ObjectDisposedException should be caught by the SerialPort, not by the user." I'd like to take a look on source code for serialPort. How can I do it?

• What is the command to check if a command's results mention OK?

  - by Manuel

  Alright, so I was playing around with changing MTU size and wanted to make a batch file to automatically lower it and then raise it later. This is probably simple, but I just can't figure it out. Point is, is there a way to run a command, which would normally echo out "ok" but check to see if it does say ok? And if it doesn't say ok then, to end the rest of the file from running and exit out. The command I'm using is netsh interface ipv4 set subinterface "Local Area Connection" mtu=386 store=persistent which, as I mentioned above prints out an OK. I just want to check if it did run correctly, and if not, then do __

• Who's using Ruby on Rails in production?

  - by Jekke

  I've been kicking around Ruby and the rails framework and have been considering recommending to a client-of-a-client that they use it to rebuild their site, which is currently built in very bad ASP classic that will have to be rewritten from the ground up regardless of what technology is used. One thing I'm missing from my pitch is a list of major sites using Ruby-on-Rails. Are there any yet?

• PCI max throughput

  - by allentown

  Hypothetical here, but I want to understand. Say I have a hand me down machine, 4 PCI slots, 64-bit 33 MHz PCI. How much data can that PCI bus handle? System bus is 133 MHz. I want to use one slot for a SATA II card, and the rest for Gig-E cards, building out as fast a NAS as I can. I think one slot may be AGP2x, so that leaves me 2 for Gig-E and one for SATAT II. Will I saturate, what is the max bandwidth of the PCI bus?

• mod_cache serving the wrong content

  - by J. Pablo Fernández

  I'm trying to use mod_disk_cache to speed up a web site that is running on WordPress. Whenever I enable it with CacheEnable disk / and the rest being the stock Ubuntu configuration I start to get the wrong results. When I see the main page it's fine, but when I go to a specific post I get a RSS feed instead. Like if the cache is returning the wrong content. I've disabled my RewriteRules as it seems mod_cache doesn't work with that. I'm not even sure where to start to debug such a thing. Any ideas?

• Can zlib.crc32 or zlib.adler32 be safely used to mask primary keys in URLs?

  - by David Eyk

  In Django Design Patterns, the author recommends using zlib.crc32 to mask primary keys in URLs. After some quick testing, I noticed that crc32 produces negative integers about half the time, which seems undesirable for use in a URL. zlib.adler32 does not appear to produce negatives, but is described as "weaker" than CRC. Is this method (either CRC or Adler-32) safe for usage in a URL as an alternate to a primary key? (i.e. is it collision-safe?) Is the "weaker" Adler-32 a satisfactory alternative for this task? How the heck do you reverse this?! That is, how do you determine the original primary key from the checksum?

• Is there any syntax checker for knockout.js?

  - by YMC

  I like knockout.js, the only problem is Visual Studio knows nothing about this framework, so it does not prevent me from silly things like assigning some value to observable property with '=' operator which makes it regular property, and it's not easy to reveal at compile time and often at runtime even. I wonder is there any syntax checker/highlighter for Visual Studio 2010 that helps me prevent faults like this? What about VS 2011? It might be a great help for developers who are new to knockout. Thanks

• Choosing a low cost wildcard SSL cert (PsotiveSSL, RapidSSL, or other)?

  - by Malcolm

  I'm looking to put in place a wildcard SSL certificate for a server that will be providing REST style web services to multiple subdomains. We use NameCheap.com for our DNS services and they offer a choice of 2 very competitively priced wildcard certs: PositiveSSL Wildcard $129.99/yr RapidSSL Wildcard $148.88/yr Is there any reason to choose one of these branded certs over the other? Or are there problems with these low cost certs that we should aware of? If so, what SSL vendor/products do you recommend and why do you recommend them? Thank you, Malcolm

• Examples of IOC/DI over Singleton

  - by Amitd

  Hi, Just started learning/reading about DI and IOC frameworks. Also I read many articles on SO and internet that say that one should prefer DI/IOC over singleton. Can anyone give/link examples of exactly how DI/IOC eliminates/solves the various issues regarding the Singleton pattern? (hopefully code and explanation for better understanding) Also given a system has already implemented Singleton pattern, how to refactor/implement DI/IOC for the same? (any examples for the same?) (Language/Framework no bars..C# would be helpful) Thanks

• XNA MediaPlayer fastforward/rewind

  - by bufferz

  Using XNA 4.0, I am currently playing songs from the user's PC/XBox360 using the following: Microsoft.Xna.Framework.Media.MediaPlayer.Play(Song song); I see that MediaPlayer has a static Property PlayPosition that, as I've researched, used to be a get/set property, but it has been updated to get-only. Are there any other methods/tricks I can use to explicitly set the playing position of a currently playing song?

• Language of variable names? (native foreign language speakers)

  - by Jj

  We are a spanish speaking development team, we code in django and we all are pretty fluent in english, as all documentation, sample code, APIs, etc come in english. On our last project we chose to name all the variables, class names, modules, files and such in english, even though the whole application was in spanish, we kept a strings file where all our spanish was stored. We did this because it seemed more natural to read the whole code in one language, since keywords, constructs and dependencies have names in english. On new projects we are starting, we are having second thoughts about other teams mantaining our code or just having 3rd parties having to deal with templates or context in spanish. Do you know of any best practice on this matter?

• Recycle a project name?

  - by deamon

  I want to start an open source project, but my favourite project name was already used for a framework with the same goal. This project was never popular, had only two active days with commits at Google Code and is dead since four years. In other words: the project is irrelevant but the name is in use at Google Code and ohloh (the same dead project). The .org domain would be available. Would it be ok to reuse this project name?
