How to use DVB on ArchLinux (with an em28xx chip)?

Hi there,
I'm trying to figure out how to use my Terratec Cinergy Hybrid T USB XS on ArchLinux. It should use the em2880 chip.
I think that the correct kernel modules are already bundled with the latest kernel version:
bash-3.2# lsmod | grep 'em28'

So it seems that the device has been recognized.. I downloaded the firmwares from http://konstantin.filtschew.de/v4l-firmware/ (the v2, since it is the 0ccd:005e version). I've also extracted the xc3028-v27.fw from the windows drivers using extract_xc3028.pl, since dmesg was complaining for the missing file.
However, Kaffeine doesn't recognize the DVB device, and I can't get any other player to work with it.
Is the kernel-bundled em28xx module broken for this device? I remember that I could make this USB dongle work some months ago in an Ubuntu setup, compiling the v4l from sources - do you think that this is required? I see many people can't compile it with the latest kernels.. and don't know exactly where to start.
Any help would be very appreciated.. thank you

Anybody can explain me what's the difference between /dev/video* and /dev/adapter*/* ?
I tried to cat my /dev/video1 (sometimes, plugging out and in the adapter, it gets assigned to video1) and some weird stuff is actually received so I decided to try a frequency scan.. I prepared the frequency file for my local muxes, installed the linuxtv-dvb-apps package, and tried to scan:
bash-3.2# scan ./it-Roma
scanning ./it-Roma
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
main:2247: FATAL: failed to open '/dev/dvb/adapter0/frontend0': 2 No such file or directory
(also triend to play with the -f, -d and -a options to switch on adapter1, demux1 and frontend1)
Now, those devices was not created at all in my system.. isn't v4l supposed to create them, once recognized the dvb device?

How to use Two main windows with in a page in script ?

Hi any body explain me...
How to use Two main windows with in a page in script ?
with header data in one main window,
& Item data in other main window.

HI..,
u need to go for SPLITTING THE MAIN WINDOW !!!
Main windows in page windows allow you to format text in multiple columns. Define an area in the page window, in which to position the main windows.
Here is the procedure !!
-->Create a page window and assign it to a page.
Choose Edit --> Main windows.
A dialog box appears.
-->Enter values in the fields Area width and Area height in accordance with the input guidelines for main windows.
-->Enter values in the fields Spacing and Number in the Horizontal group if you want to use multiple columns. You can ignore the fields in the Vertical group.
Determine how many columns and line areas are required for label printing. Then enter the corresponding values in the fields in the Horizontal and Vertical groups.
-->The value in the field Left margin varies from main window to main window if multiple columns are used. The following applies:

Left margin of current column + Window width + Horizontal spacing = Left margin of next column
In label printing, the field Upper margin also varies from main window to main window:

Upper margin of current main window + Window height + Vertical spacing = Upper margin of next main window
-->Enter a value in the field Start position.
This is a counter. Enter a starting value which is equal to or greater than 1.
-->The main windows are added to the list.
-->Save your form.

How to use JavaMail 1.4 with Oracle Application Server 10g (9.0.4.0.0)

Hi all,
I'd like to know if it's possible and how to use JavaMail 1.4 with Oracle Application Server 10g (9.0.4.0.0), Windows version.
With the following code, I can see that the mail.jar used by the server is the one included in the jdk installation :
// I'm testing InternetAddress.class because I want to use commons-email-1.2.jar that requires mail.jar 1.4 (or higher) and activation.jar 1.1 (or higher)
// and I know that inside the commons-email-1.2.jar file, I need to call the InternetAddress.validate() method that throws a java.lang.NoSuchMethodError: javax.mail.internet.InternetAddress.validate()V if it is used with mail.jar 1.2.
Class cls = javax.mail.internet.InternetAddress.class;
java.security.ProtectionDomain pDomain = cls.getProtectionDomain();
java.security.CodeSource cSource = pDomain.getCodeSource();
java.net.URL location = cSource.getLocation();
System.out.println(location.toString());
This code returns : file:/C:/oracle/app/jdk/jre/lib/ext/mail.jar and this mail.jar file has an implementation version number: 1.2
- I've tried to include my own mail.jar (1.4.2) and activation.jar (1.1.1) files in the war file that I deploy, but it doesn't work (the server still uses the same mail.jar 1.2)
- I've tried to put the mail.jar (1.4.2) and activation.jar (1.1.1) files in the applib directory of my OC4J instance, but it doesn't work (the server still uses the same mail.jar 1.2)
- I know that a patch exists : I've read the following document: How to Make Libraries such as mail.jar and activation.jar Swappable ? [ID 552432.1]
This article talks about the Patch 6514136, but this patch only applies to : Oracle Containers for J2EE - Version: 10.1.3.3.0
Can you please help me ?
Thanks in advance for your answers,
Laurent

I strongly suggest to upgrade to AS 10.1.3 to get this.
Think of future support of AS 9.0.4. You will get not critical patch updates anymore.

How To Use Your Own Router with Out Loosing Verizon's FIOS Services

How to use your own router with Verizon’s FIOS Service
First, you need a basic understanding of how FIOS works but unfortunately there are two types of FIOS systems out there. All of the systems utilize a fiber optic cable to bring TV, phone and internet to your location over one optic cable. In addition these systems provide interactivity including widgets, remote DVR, movies on demand and so forth via an IP (Internet Protocol) signal. Your STB (Set Tip Box) requires both a video and IP signal. The IP signal is necessary for all of the aforementioned interactivity. The fiber cable terminates at the Optical Network Terminal or ONT for short. The ONT converts the optics into a digital signal that can be utilized by ones equipment. From the ONT your video, phone and internet are provided to the location. This is where things can differ as the internet signal can be provided via a coaxial (MoCA or Multimedia over Coax Alliance) or RJ45 Cat5 (Ethernet) cable. It is important to identify and understand the differences of these two setups. In my case I have my internet entering via Ethernet cable, which in my humble opinion makes things a heck of a lot easier.
How does one tell the difference? In most cases it’s rather simple; just look at the Verizon’s router WAN (Wide Area Network) Port. Does it have a RJ45 (Ethernet) or Coax (TV cable Cord) going to it? If the router’s WAN port doesn’t have a coaxial connector then one will need to convert the MoCA signal into a usable Ethernet signal that routers understand. The easiest way is to use Verizon’s router as a bridge. In this method the Verizon’s router simply converts the signal and passes it along to your own router. The challenge is to try to maintain the interactivity that FIOS TV provides. Because of this one needs to supply the IP routed signal back to the FIOS router. There are multiple methods for doing this and I would recommend investigates which one make the most sense.
In my particular case the IP signal was provided by Ethernet. Again there are various ways of installing one’s own router. The hardest is to utilize Verizon’s router as a bridge. This setup requires configuring Verizon’s router as a bridge and also creating a VLAN (Virtual Local Area Networks). In addition one needs to set up their own router so it will work with the various routing tables and networks. For me this is too complex for the average person and it can be difficult to trouble shoot if something goes wrong. Please consider that Verizon will not support utilizing third party routers.
The easier method is to request an Ethernet signal (if you don’t already have one) from their ONT. I would highly recommend getting your hands on a NIM or Network Interface Module. This device is used to convert Ethernet to Coaxial so it can be fed back to your STBs. These can be purchased online and Verizon technicians can be a valuable resource with these sorts of acquisition. At the very least they can point you to the right direction. Once you have a NIM the rest is rather simple.
Log into the current Verizon Router.
Located the router’s MAC address and copy it down.
Go to the port forwarding section and copy down the Applied Rules.
Example:
Network Computer/Device: 192.168.1.100:63145
Application & Ports Forward: Application UDP Any -> 6347
Note: There may be up to three entries for each one of your Set Top Boxes.
Look at your current device list, typically found on the home screen. Copy down your STB MAC and IP address.
Example:
IP-STB1
Connection Type: Ethernet
* IP Address: 192.168.1.100
IP Address Allocation: DHCP
*MAC Address:                07:73:fFe:ad:8b:3f
* Things you will need to write down
Go to the network section and look for the main Ethernet connection. Select this and then select more setting, typically found at the bottom. Release the current lease.
Remove the Verizon router
Install your router
Connect the NIM by plugging in an Ethernet from one of the routers LAN (Local Area Network) ports to your NIM. Then connect the coax cable, the same cable that was used by Verizon router.
Set you DHCP routing IP pool to accommodate Verizon’s STB IP’s (note their IP’s start at 192.168.1.100)
Go to DHCP section and reserve the STB IP’s by inserting the IP’s and MAC addresses. This shall ensure that nothing else utilizes the same IPs as the STBs thereby preventing IP address conflict.
Add the port forwards from Step 5 above.
Clone Verizon’s Mac Address utilizing the info from step 2
Finish setting up the router in typical fashion.
Unplug and re-plugin your STB’s and test functionality. It’s best to try using a widget or Movie on demand function.
Note: if the new router can net get an internet signal contact Verizon’s support and have them release the IP and reset the ONT.
EVERYTHING should be working at this point.

3 Go to the port forwarding section and copy down the Applied Rules.
Example:
Network Computer/Device: 192.168.1.100:63145
Application & Ports Forward: Application UDP Any -> 6347
Note: There may be up to three entries for each one of your Set Top Boxes.G
Your display obviously is not like mine as mine does not dosplay the port associated with the ip address
whatever, the STB's start at 192.168.1.100 and icement by 1 for each
the port addr's will be 63145 alo incrementing by 1
there is 1 entry for each in my pf list
however each ip addr also has a port entry starting at 35000 also incrementing by 1 for each ip addr
For some unknow reason these are duplicated e.g I appear to have 11 entries exaactly the same for each stb and as the fios services rules have no action switc there is nowhere to delete the extraneous garbage.
Why do you clone the mac addr??

Dear Yaseen,
To get the value in formula cumulative,after you have created the formula for that particular key figure,go to edit and click on tab "calculations".
In that select overall result as 'count all values not equal to zero' and single result as 'count all values not equal to zero' .
And mark the cumulative check box underneath.

Krishna,
It is not possible to deactivate the CHANGE option in themenu bar using the method disable_functions of cass CL_CTMENU. This method allows you to deactivate only the function codes of the CONTEXT MENU, which is available only when u press the left mouse button.
U can use the SET PF-STATUS 'XXX' EXCLUDING fcodes option to disable the CHANGE.

How to use airport time capsule with multiple computers?

I'm sure there are some thread about this but i couldn't find it... so sorry for that but hear me out! =)
I bought the AirPort Time Capsule to back up my MBP
And so i did.
then i thought "let give this one a fresh start" so i erased all of it with the disk utility and re-installed the MBP from the recovery disk.
I dont want all of the stuff i backed up just a few files and some pictures so i brought that back.. so far so good.
Now i want to do a new back up of my MBP so i open time machine settings, pick the drive on the time capsule and then "Choose" i wait for the beck up to begin, and then it fails. It says (sorry for my bad english, im swedish haha) "the mount /Volume/Data-1/StiflersMBP.sparsebundle is already in use for back up.
this is what i want:
i want the "StiflersMBP.sparsebundle" to just be so i can get some stuf when i need them. it's never to be erased.
i want to make a new back up of my MBP as if it's a second computer...
so guys and girls, what is the easiest and best solution?
Best regards!

TM does not work like that.
If you want files to use later.. do not use TM.
Or do not use TM to the same location. Plug a USB drive into the computer and use that as the target for the permanent backup.
Read some details of how TM works so you understand what it will do.
