How to convert videos(ingcluding DRM protected) on Mac and transfer iP

Tue, 28 Apr 2009 01:52:18 -0700

Nowadays, Apple Mac is more and more popular among our life. But there are few high quality compitible tools for it. Today I’d like share three useful software for all the Mac users to help convert videos(ingcluding DRM protected) and transfer iPod to Mac.
It includes three parts:
Part 1:How to convert video files on Mac with iskysoft Video Converter for MacPart 2:How to remove DRM protection from iTunes music WMA M4P M4A etc. on Mac with AppleMacSoft DRM Converter Part 3:How to transfer iPod to Mac with Aiseesoft iPod to Mac Transfer

Part 1:How to convert video files on Mac with iskysoft Video Converter for Mac

Step 0: Download and install iskysoft Video Converter for Mac( Intel Version or Power PC Version）

Step 1: Add Video files
Click the "Add Files" button to add video files to the program by automatically selecting an appropriate encoder for the video files you want to convert.
This mac video converter supports batch conversion, so you can import several multimedia files at a time so that you can convert several videos or audios at one time.
Step 2: Output Settings
You can use the default setting which works great, if you don’t want to use it, you can:
Choose the output format from the format drop list.
Choose the audio format (mp3, wav, ac3, ogg, ape) if you just want to extract audio from videos on Mac.
Choose the destinaton by click “Brouse” button on the right of “output”
Choose the video and audio encoding settings by clicking the “Settings” button.

Step 3: Start Conversion
Click the “Convert” button to start conversion

More functions about this software: During the conversion, you can use the functions of “crop, trim, effect,merge into one file”.You can also name your files in the “File name” line. They are all very easy to use and work great.Just follow the instructions on it, you can edit your video as your will.

Part 2：How to remove DRM protection from iTunes music WMA M4P M4A etc. on Mac with AppleMacSoft DRM Converter
AppleMacSoft DRM Converter for Mac can remove DRM from iTunes, crack DRM protection, convert DRM M4P to MP3, M4A to MP3, WMA to MP3, iTunes to MP3, and more. It is the legal way to convert iTunes DRM protected files to unprotected music files. It is a DRM copy-protected audio and music converter designed for burning DRM protected music to a special virtual CD-RW drive where you can easily get unprotected MP3, AAC, Apple Lossless, AIFF, WAV files ready for use on any player. AppleMacSoft DRM Converter for Mac uses a CD-RW and iTunes itself to convert all of your DRM music files to standard format files (MP3, AAC, Apple Lossless, AIFF, WAV) that you can use with ipod player.

Step1. Drag AppleMacSoft DRM Converter for Mac from the Disk Image or CD to your Applications folder
Step2. Open your Applications folder
Step3. Double click AppleMacSoft DRM Converter for Mac
Step4. If needed enter the word for Protected in your local language in AppleMacSoft DRM Converter for Mac in the field titled: Identify protected tracks by looking for this word in Kind
Step5. If you want to convert a specific playlist instead of your entire library then pick the playlist from the pop up menu titled: In this playlist
Step6. Optionally, if you want to convert to a format other than MP3 (the default) then pick the format from the pop-up menu to the left of the Dump DRM button
Step7. Click the Convert DRM button.

Note: When you click the Convert DRM button, AppleMacSoft DRM Converter for Mac will ask you to insert a CDRW. AppleMacSoft DRM Converter for Mac will then find all the protected tracks and start burning them in groups of 10-20 to the CDRW and ripping them back to your selected, unprotected format. All your unprotected tracks will be placed in a new playlist called something like MP3 from AppleMacSoft DRM Converter for Mac (the MP3 will change if you picked another unprotected format) and your original tracks will be left untouched. Its going to take some time so you should have something else to do, not on your computer, and just check on AppleMacSoft DRM Converter for Mac now and then to make sure things are still happening.

Alternate function for Sleep

Sun, 15 Feb 2009 14:48:53 -0700

Hi there. I'm looking for an alternate way to Sleep. I want a pause function that acts the same in Batch Programming. An example would be if you were to write pause in a notepad and save it as .bat and then open it it would show you this message "Press any key to continue." This is the type of function I'm looking for. Believe me, I've searched on google daily trying different search terms and I've also searched this site and many ruby websites. Do you think you can help me out?
Thanks.

server 500 error

Sat, 07 Feb 2009 07:21:28 -0700

Hello,
I have problem that I will try to explain I am a web designer not a developer I will do my best, I have run into some issues with this script I have a template of a system to sell hosting alongside my web design, I have moved some of the code from the index.rhtml to the header.rhtml and also to a new separate page so the login is on its own page. I now receive server 500 error when trying to log in .Once the attempt to log in has been made you recieve internal server error 500 but if you direct back to home url you have actually been logged in. It also happens when creating a new account although the log in and new sign up are successfulyou are directed to a page called front-page.rhtml this is where the error is coming from. The login code is below

<% if !logged_in? %>
<h2>Log In</h2>
<form accept-charset='utf-8' method='post' action='login'>
<p>Email Address: <input type='text' size='30' name='username'/></p>
<p>Password: <input type='password' size='30' name='password'/></p>
<p><input type='submit' value='Log in'/></p>
</form>
<p>(Click <a href='password-reminder'>here</a> if you have forgotten your password)</p>
<% else %>
<p>Hello <%= contact.name %>. (<a href='logout'>log out</a>)</p>
<% end %>

the only code on the front-page is

<% else %>

I guess there is a script file somewhere on the server which has the directives of where the code should be executed from? which is causing this error to occur as its coming from the wrong place I hope somebody could advise me or point me in the right direction. I did have similar problem before on and different piece of code and placing

<%= url_prefix %>

on the get action did the job not this time though
many thanks

rhtml - controller race

Fri, 02 Jan 2009 00:32:17 -0700

Hi,
here is my problem:

One user, one (new) modem, one computer. He wants to connect to Internet
with the modem.

The user that wants to connect with the modem first is redirected to
ruby application (by modem firmware -> www-is on VPN), after configuring
the settings the redirect is removed but the rhtml is not rendered
because the application (web/ruby) is on VPN and it has no access
anymore to it.

Now, I am a beginner to ruby but I did some tries and searches and still
cannot make it that the text and some links that say yey u are
successfully connected to internet, here you have some docs about it...,
to be first displayed and then the settings to take effect and redirect
removed... in the same step, controller method <-> rhtml. The settings
they take effect and some text or none is displayed, it is a race on
what is first, rendering the rhtml or controllers method with get
requests to the modem is executed ... first.

Thanks guys!

summary:
what I am still looking for is a way of first to display the rhtml and after fire the get requests.

One request is like this:

url = URI.parse("http://"+ session[:ip_addr] + "/blabla.wl?var1=1&...")
req = Net::HTTP::Get.new(url.path+"?"+url.query)
req.basic_auth "xxx","xxx"
res = Net::HTTP.start(url.host, url.port) {|http| http.request(req)}

and now is in controller, but I did try it in between <% %> in template rhtml but didn't displayed the template also.

New and with a problem.

Mon, 09 Jun 2008 16:41:41 -0700

Hi, all
I've just entered into the world of programming and, I guess I chose ruby.
I'm trying to make this work but it doesn't seem to wan't to
I don't know why it shows both ifs
If some one could help, I'd be really appreciative!

puts 'Speak up Sonny I can\'t hear you.'
talk = gets.chomp
if talk == talk.capitalize or talk.downcase
then puts 'What? Sonny speak louder! Like THIS.'
if talk == talk.upcase
then puts 'no not since'
end
end

what is printed by this function?

Sat, 08 Mar 2008 18:09:26 -0700

Hey everyone.. i never used Ruby before ... so trying to learn more about it's techniques...
can someone please tell me what will be the output of the following program segment assuming that the puts function prints its arguament on standard output followed by a newline.

      def h(k)
        k.call
        puts "in h"
      end

      def g(k)
        h(k)
        puts "in g"
      end

      def f()
        callcc {|cc|g(cc)}
        puts "in f"
      end

      f

thank you

Ruby vs. C++

Thu, 18 Oct 2007 11:32:40 -0700

I have just posted on my blog the reasons why I think C++ is the one true programming language (I am being slightly tongue in cheek here). I used 10 questions to compare it to other languages. Unfortunately I have not been able to compare it to Ruby as I don’t have any significant experience of Ruby development. Would anyone be willing to score Ruby for me?

How can Ruby search for files on my Windows network computers?

Tue, 15 Aug 2006 08:20:00 -0700

I currently use a Python Script that looks across my Windows network for computers having a specific out-of-date file. The idea is to run the script, get a list of computers with the out-of-date application, and then replace the application on the identified computers. The script generally works, but I would like to shift to using Ruby as our primary scripting language.

Any ideas?

Thanks in advance.
