How can I implement a new protocol over IP

Hi,
I want to implement a new protocol (my customized one) in solaris 8. This protocol will be something like UDP and will be using IP for communication.
So how can i use IP stream module for that?
thankx
prasenjit

I can give you some pointers regarding this. Although, I implemented protocol below IP.
- Look for information on ipsecah and ipsecesp. These are pseudo devices on top of IP for Solaris 8.0.
- Check how the protocol stack is built while booting.
- If you intend to implement a module, rather than a driver then things might be little easy. You can push your module on top of IP. See man for "sad" and "autopush" mechanism
- Sample drivers and modules from SUN are of great
help. I came to know about the sample drivers very late.
Otherwise, I would have saved some time.
- Unix System V network programming by Rago is a very good reference.
I hope this helps.

How can we suggest a new DBA OCE certification for very large databases?

How can we suggest a new DBA OCE certification for very large databases?
What web site, or what phone number can we call to suggest creating a VLDB OCE certification.
The largest databases that I have ever worked with barely over 1 Trillion Bytes.
Some people told me that the results of being a DBA totally change when you have a VERY LARGE DATABASE.
I could guess that maybe some of the following topics of how to configure might be on it,
* Partitioning
* parallel
* bigger block size - DSS vs OLTP
* etc
Where could I send in a recommendation?
Thanks Roger

I wish there were some details about the OCE data warehousing.
Look at the topics for 1Z0-515. Assume that the 'lightweight' topics will go (like Best Practices) and that there will be more technical topics added.

How can I create a new ring tone for my iPhone 4?

How can I create a new ring tone for my iPhone 4? I followed the Garage Band process and ended up with the ring tone I want as a AAC audio file. It got stored in my iTunes a a song rather than a ring tone. How do I make it a ring tone vs. a song? I tried dragging it t the Ring Tone category at the bottom of the ITunes list, but it won't alloow me to move it?

There's also an easy to use Applescript over at Doug's Applescripts for iTunes. It automates the whole thing. All you do is set the start and stop time on a file in iTuens and run the script. It will do everything else.

How can I configure my new Mac Pro to output the timeline via HDMI

How can I configure my new Mac Pro to output the timeline in FCP 7 (yes, I have X, but I'm using 7 right now). I have two monitors running from TB2, but want to have the third for a client monitor.
If I use all three via TB2, it's literally three monitors, and I want to edit on my CineDisplay. I only want the client to see the timeline video on the third monitor. When I hook up HDMI I get no signal, in fact, I can't have the HDMI cable hooked up for TB2 to work with the third.
Thanks,

If you use all ThunderBolt displays, or stick with DisplayPort and Mini DisplayPort (free conversion between the two with only a cheap cable) you can have up to six displays.
If you attach "legacy" displays with "any-old adapter", you can have up to two, and the built-in HDMI counts as one if you use it.
Any more requires ACTIVE Adapters.
The US$100 Apple ACTIVE Mini DisplayPort to Dual-Link DVI adapter works in every case, even displays over 1920 wide.
StarTech and Accell make US$35 ACTIVE adpters that work for displays up to 1920 wide.

How can I create a new TC backup with ethernet, so I don't have to wait two days for a new wireless backup?

How can I create a new TC backup with ethernet, so I don't have to wait two days for a new wireless backup?
Several times in the last year, I've gotten a message that Time Machine needs to completely redo my backup. Using the wireless connection, this takes almost two days. Is there a way to do the backup with ethernet and then switch back to wireless? Thanks.

May I know what is needed to make sure the MacBook is able to see Time Capsule on ethernet?
Connect an Ethernet cable from one of the LAN <-> ports on the 2Wire gateway to the WAN port (circle of dots icon) on the Time Capsule.
If AirPort Utility cannot "see" the Time Capsule now, you will need to perform a "hard reset" by holding in the reset button for 7-8 seconds or so and then reconfigure the Time Capsule. You can use the same Time Capsule name and password, etc. as before.
Configure the Time Capsule to "Create a wireless network" and select the Bridge Mode option when it appears during the setup using AirPort Utility.
Once the Time Capsule is configured, restart the entire network again. Power down everything, start the 2Wire first and then start each other device after that one at a time about a minute apart.
Now you can connect your Mac directly to one of the LAN <-> ports on the Time Capsule for the backup using another Ethernet cable. In general, about 20-25 GB per hour will transfer.
The Time Capsule will broadcast a much faster wireless network than the 2Wire can provide, so you might want to leave the setup "as is" for awhile after the first backup is complete. If you decide to use the Time Capsule as your main wireless access point, you would want to turn the wireless off on the 2Wire since two wireless networks in close proximity can create interference problems.
Or, if you want to use the wireless on the 2Wire, you could turn off the wireless on the Time Capsule. Then backups will occur over the 2Wire wireless, or over Ethernet.
I don't really recommend the "Join a wireless network" setting on the Time Capsule for most users, but you could go back to that setup as well if you want after the first backup is complete.

How can I create a new recovery key if you automatically removed my trusted device after update do iOS 8?

How can I create a new recovery key if you automatically removed my trusted device after update do iOS 8?

Hey -
I need to do the EXACT same thing, but have no idea how. Has anyone out there done this?
My situation is a tad different..this is a new Mac (and I'm a brand new Mac user). Tons of querks occur under my original account (videos won't run, Safari won't support certain plug-ins). I spent 6 hours on the phone w/ 4 different Apple Reps and nobody could fix it. A rep finally looked at my MacBook Pro in person today. He created a new account just to see if that would work and under that new account, everything works perfectly fine (no querks, can view video). He tried switching a million settings in my original account to no avail.
He said to create a new account (as he did) and move my files over to the new account and then go back to the original and delete it. How do you do this?! I can't figure it out! I've got a new account created, but of course it just has the default folders in it w/ the little red icons next to them! Thanks in advance!

Elements 11 vs 13: how can I add a new place tag to my PSE13 database without using the wretched and totally inadequate map technology that Elements 13 wants to impose.

HI,
I have recently installed Elements 13 having used Elements 11.0 successfully to build a database of 30,000 plus images indexed by place, people, and photo date. Elements 11 allowed me to add new places which are meaningful to me but which are a complete mystery to the mapping technology of Elements 13. For example some years ago I lived in London in a road called Argyle Road. In elements 11 I could enter the place tag as Argyle Road. In Elements 13 I am required to locate Argyle Road on the map, but the map presupposes that the Argyle Road I am referring to is in Ealing in West London. It is not!
I now live in a place called Broadsands but the Elements 13 Map places this 0.5 miles away from what I would describe as Broadsands.
So the question: how can I add a new place tag to my database without using the wretched and totally inadequate map technology that Elements 13 wants to impose.

Thank you for your quick response, BalusC. I really appreciate your answer.
Yes, you are right. If I manually code the same amount of those components in the JSF pages instead of generating them dynamically, the server will still run out of memory. That is to say, JSF pages might not accommodate a great deal of concurrent visiting. If I upgrade the server to just allow 1,000 teachers making their own test papers at the same time, but when over 2,000 students take the same questionnaire simultaneously, the server will need another upgrading. So I have to do what you have told me, using JS+DOM instead of upgrading the server endlessly.
Best Regards, Ailsa

How can we implement a regular expression in if condition?

hi,
could any body tell me how can we implement regular expression in if condition?
if a page contains links with .html,.pdf,.img etc as href paths then i should only retrieve the links whose href path is .pdf .
any idea
thanks in advance

Pasumarthi,
Here is some VBA that should do the trick. This was created against the empirix homepage. www.empirix.com.
Private Sub RSWVBAPage_afterPlay()
Dim objReg As New RegExp
Dim objMatch As Match
Dim doc As String
'Get the html
RSWApp.GetHtml doc
'set parameters for regular expression searching and matching
With objReg
    'find all occurances
    .Global = True
    .IgnoreCase = True
    'regular expression pattern specified here
    .Pattern = "a href=(.+?)pdf"""
End With
'Loop through the matches and write them to the results log.
For Each objMatch In objReg.execute(doc)
    RSWApp.WriteToLog objMatch.Value
Next
Set objReg = Nothing
End Sub
