I'm trying to setup an ipsec system as follows but the documentation is maddening and most walk-through guides I've found differ from exactly what I'm trying to do (and are low on explanation). So, my first, simplest question is, can I setup a tunnel mode, pre-shared key, where a remote client behind a NAT can connect to the server using l2tp/ipsec? The server is also behind a NAT (I cannot change this; although port-fowarding is available). When the tunnel is established all client traffic should go through the server machine, including traffic to/from outside the server's subnet. Is this configuration possible with ipsec/l2tp?
Most of the guides I'm looking at envision either one or two of the endpoints as having a public IP, and then allowing secure access to the subnet behind it which is a slightly different configuration. I'm using openswan under linux right now, although that detail shouldn't affect this question. Shadowjams ( talk) 01:09, 22 August 2012 (UTC)
Hey last night suddenly all movie files (.mkv, .avi etc.) that previously worked fine suddenly had their audio out of sync to varying degrees, sometimes by as much as a minute or more.
I assumed that perhaps the CPU was doing a heap of work or perhaps the HDD was being written/read to by something else slowing it down but both of these theories were proved wrong when I copied the files across the network and two other computers had the same problem.
Nobody else on the internet seems to have ever had this problem and i'm straight up confused.
they're all running win7 with avast antavirus, using windows media player or VLC for playback, and connected by shared drives on the homegroup. -- Benjamint 04:20, 22 August 2012 (UTC)
Pressing "J" or "K" while a file is playing will change the audio sync. Perhaps you pressed them accidentally on all three machines while using another program which required the use of those keys? You can check the audio desynchronization settings at Tools -> Preferences -> Show settings -> all -> Audio -> Audio desynchronization compensation. 92.233.64.26 ( talk) 17:17, 22 August 2012 (UTC)
One of my translation agents wants me to use ftp for file transfer, rather than giving me a server to log in to, or sending files by email. However, the ftp address is in an email which will end up being buried sooner or later. I tried to add a desktop shortcut (as this is a regular agent), but I just ended up with a Firefox shortcut, rather than the usual Win7 ftp window, which is what I wanted (the Win7 ftp window doesn't update loads of addons everytime you load it, causing you to close lots of tabs). Is there a way to do this? KägeTorä - (影虎) ( TALK) 07:13, 22 August 2012 (UTC)
Given the following statement, using the condition operator in Java, how is the initial boolean statement interpreted? Is it 'if c is equal to a and a is less than b'?

Copy the following text:
Mängel
Now place it into the utf-8 decoder. It states that the second character (ä) is an incomplete character in a multibyte sequence, and so it is dropped. This is causing confusion for my bot, because the PHP regular expression doesn't know what to do with the mangled character (yes, this is ironic; no, it is not intentional).
What in the world is going on with that character, and how can I get my regular expression to recognize it short of brute force altering the text? Magog the Ogre ( talk• edits) 17:02, 22 August 2012 (UTC)
Nevermind, the answer is far stupider than it appears on the surface: I had part of the regular expression typed in the wrong location. I would still be interested in knowing why this site and the terminal window in Ubuntu consider this character to be incomplete and disregard it.

I have a webpage with many bridge hands on it. Each hand is separated by a horizontal rule. If someone prints the page out I would like to have the page breaks in the vicinity of the HR, ideally after, rather than split a table up across a page boundary.
I've tried
<hr align=center width="80%" size=3> <div style="page-break-inside:avoid"> <h3> Board 21 </h3> <p> Dealer: N <br> Vulnerability: N/S </p> <table cellpadding=1 border=0> <tr> <td width=80> </td> <td width=80> ( 16 ) <br> ♠JT97 <br><font color=#ff0000>♥</font>A3 <br><font color=#ff0000>♦</font>AK94 <br>♣A63 </td> <td width=80> </td> </tr> <tr> <td> ( 6 ) <br> ♠AQ62 <br><font color=#ff0000>♥</font>864 <br><font color=#ff0000>♦</font>6532 <br>♣87 </td> <td> <img src="brg_tbl.bmp" width=70 height=70> </td> <td> ( 9 ) <br> ♠854 <br><font color=#ff0000>♥</font>KQJ52 <br><font color=#ff0000>♦</font>T7 <br>♣QJ9 </td> </tr> <tr> <td> </td> <td> ( 9 ) <br> ♠K3 <br><font color=#ff0000>♥</font>T97 <br><font color=#ff0000>♦</font>QJ8 <br>♣KT542 </td> <td> </td> </tr> </table> <p> </p> </div> <hr align=center width="80%" size=3>
But it doesn't appear to work in either IE or Firefox. Any ideas what I should do? -- SGBailey ( talk) 17:09, 22 August 2012 (UTC)
When I upgraded to Fedora 17, I got GIMP 2.8. It works otherwise very nice, but I have some questions:
What is it called? Old PC game from the 90's maybe earlier, you play a penguin (?) I think, definately set in a freezer and there are ice cubes and you can push the ice cubes to crush these purple things, and some of the ice cubes have got purple things in them and if you push them the purple things wake up, and you can also electrify the walls of the freezer and stun them, and it's a 2d game, and what was it called and how can I play it again? Thanks Horace Grundle ( talk) 19:33, 22 August 2012 (UTC)
Now that I've upgraded to Fedora 17, I've also installed Xine. But when it starts up, it immediately pops up a message box about an unknown codec. I tried to play a .wav file I had recorded from VICE, but it also gave a message about an unknown codec. Presumably I've only installed the player itself, not any codecs. I just typed yum install xine
. How can I install the codecs? I would also like to be able to play the numerous DVDs I've bought fully legally, but can't play with 100% free software thanks to copyright restrictions. I think I have to install xine-lib-extras-nonfree
or something, but where can I get it from?
Also, is there any way to convert .wav files to .mp3 files so I could upload them to my Creative Zen Vision W and use it to play Commodore 64 game music when I'm carrying it around? JIP | Talk 19:39, 22 August 2012 (UTC)
I assume varicode is used for data compression. How does ambiguity not arise when decoding a bit stream without fixed intervals? -- Melab±1 ☎ 21:55, 22 August 2012 (UTC)
Some time ago, I asked a question about a song (a Latin remix of that song to be exact) that I download that was over 3 minutes long (3:48 to be exact) and over 8 MB ( 8.41 MB to be exact), but according to the “Properties” info, the bit rate was 192 kbps, which obviously didn’t sound right. I saw that there are many download links to this song with this incorrect info. But I found a link to that remix that was over 5 MB according to the song info and 192 kbps. Now, this sounded right and I also found many download links to the song with this info.
Now, not too long ago, I downloaded a music editing software called Sony Acid Pro 7. I decided to put each song, the one with that’s supposedly over 8 MB and the other one that is over 5 MB ( 5.68 MB to be exact), on each track to check and zoom into the wavelengths of both songs just to compare to see if there was any difference in their qualities by checking out their wavelengths’ size, if there were more or less or breaks in the lines and dots, and if there were more or less details. I found out that everything was exactly the same, which means that the bit rate for the song that said 8.41 MB was right, 192 kbps, but somehow, the size information was wrong.
By the way, I also have another music editing software called Audacity. In Audacity, you can decide at what bit-rate you want to export an audio track. I decided to export the song at 320 kbps to see what the size info would say after I exported it. The info said that at 320 kbps, the size would be around 8.72 MB. This further showed that the bit rate was right, 192 kbps, but that 8.41 MB as its size was incorrect.
So how can a song that is at 192 kbps and at 3:48 in length be 8.41 MB? Why and how is the song size information wrong? What could have gone wrong? Was it the way it was compressed or the way it was produced? Willminator ( talk) 23:21, 22 August 2012 (UTC)
