Best practice for Video over IP using ISDN WAN

I am looking for the best practice to ensure that the WAN has suffient active ISDN channels to support the video conference connection.
Reliance on load threshold either -
Takes to long for the ISDN calls to establish causing the problems for video setup
- or is too fast to place additional ISDN calls when only data is using the line
What I need is for the ISDN calls to be pre-established just prior to the video call. Have done this in the past with the "ppp multilink links minimum commmand but this manual intervention isn't the preferred option in this case
thanks

This method is as secure as the password: an attacker can see
the hashed value, and you must assume that they know what has been
hashed, with what algorithm. Therefore, the challenge in attacking
this system is simply to hash lots of passwords until you get one
that gives the same value. Rainbow tables may make this easier than
you assume.
Why not use SSL to send the login request? That encrypts the
entire conversation, making snooping pointless.
You should still MD5 the password so you don't have to store
it unencrypted on the server, but that's a side issue.

Best practices for Voice over MetroRing

Hi, We have installed a MetroRing Gigabit Ethernet using 3550 and 6500 Catalyst switches. Today, only data is running, but looking at tomorrow, when voice/video be requested, I am trying to find some best practices for QoS or traffic classification. If you can point me to some of them will be great.

Hi,

Best Practice For Referencing JPEG Path Using Servlets To Prepare HTML IMG

I am migrating a legacy app from Tomcat 5 to Weblogic 11g (10.3). In the legacy app, servlets write HTML that uses relative paths for <IMG src="../images/img.jpeg"> and <script src="../javascript/js.js">. The app is deployed as an exploded archive. Unfortunately, none of the images or script are being loaded. I've tried using http://serverIP:portNum/contextName/images/img.jpeg"> but it doesn't work. I've also checked to get the name of the context in the servlet and it's the root context. Could it have something to do with me having to append .war onto the application when I deploy it? Would it help if I deployed it as a war inside an ear? Basically, I want some best practices for doing this on Weblogic 11g. There are a lot of images and javascript and I'm really hoping they don't have to be inserted using ClassLoader.getResourceAsStream()... thank you.

Best Practice:
1. Move Static files like images, css, java scripts to a web server infrastructure if available.
2. If this is not your case, then please send your directory information how you have packaged your EAR. I can advice :)

Best Practices for SAP, connections to use without BW

Hello,
Could you help me to solve a problem with Best Practices 4.31?
SAP Integration Kit XI 3.1 SP3 has 4 options :
u2022     SAP Infosets
u2022     SAP BW MDX Query
u2022     SAP BW Query
u2022     Table, cluster ou function
When I install SAP Integration Kit XI 3.1 SP3 for serveur, I have one additional service in my CCM, BW Publisher 12. This service is from SAP BW.
From the article /people/glen.spalding/blog/2010/08/04/the-full-montypart-13bobj-integration-kit-sp3-install-configure and installation guide for IIntegration Kit XI 3.1 SP3 I've learned that I need SAP BW to use Infosets dans Crystal Reports.
Dans notre installation nous avons
u2022     SAP ERP système without BW,
u2022     BOBJ Server Setup,
u2022     BOBJ Edge Integration Kit for SAP XI 3.1 SP3 server
u2022     BOBJ Client Setup,
u2022     BOBJ Edge Integration Kit for SAP XI 3.1 SP3 client
u2022     Crystal Reports 2008
u2022     Xcelsius 2008
I've got Best Practices reports via « Table, cluster ou fonction » connection. There is no problem with this type of connection !
I suppose that « SAP Infosets », « SAP BW MDX Query » et « SAP BW Query » connections should be used with SAP BW.
Could you give me your opinion about this question?
Thanks beforehand,
Malika

Hi,
the InfoSets are a connection option for the classic InfoSets in an ERP system. Would suggest you take a look at the user guide for the SAP Integration Kit

Best practice for video storage?

What is the best way for storing videos on external drives? I am a new FCP user coming from Sony Vegas. In Vegas I could import the .mts files into Vegas without the need of the complete file structure as FCP requires when ingesting to ProRes. Since Vegas worked in this manner, I store the .mts files in folders that are dated when shot. Now I'm faced with finding another program to convert to ProRes as FCP needs to complete file structure to ingest media. Another issue is that I have different types of shoots on one single flash card and I can no longer just dump the .mts files in dated folders. What is the best way of splitting up the flash card, yet keeping the required information FCP needs for ingesting media?
The solution would be to dump the videos to my external drive as soon as I'm done shooting, but most likely it's something I'll forget to do.
Anyone have any advice on storing videos that have two plus types footage of different events?

I have a tutorial that covers this...

Best practice for moving portal solution using content db from UAT to PROD

Hi,
Would like to know can we backup the database from UAT env. and restore the same to PROD. if all of my functionality is working fine in UAT env.
I have event receivers[web level features], site collection level features,custom web parts, custom permissions, saved site templates, custom discussion forums etc.
Assuming that I have my custom solution deployed on the Prod. which will activate features for those web parts and my custom application page features.
Is there any issues I can anticipate in PROD.env, if i perform this activity.
or
Is this approach not recommended by Microsoft ? if yes , whats the best approach for deploying portal solution in PROD?
Should I create teh web application, site collections, everything in PROD.from scratch.
any links regarding this approach and the bext practices / helpful info is appreciated.

Thanks Trveor for the reply.
so, I can go ahead and create the web applns, site collections and deploy my web parts, item event receivers, appln pages and my timer jobs in UAT and take the backup of the same and restore it in PROD env.
But, i ahve a doubt here , as I have few site pages created it in my site template and when i take the backupof this web apppln's content db --- [ i think i can take the backup of web appln content db through power shell] ----
will the site pages also be part of this backup?
I had some experience in prev.version of SP, wherein i have few site pages and saved site template I have taken the backup of the web appln and restore it in another farm and associate the restored content db to the
newly created web appln in the targeted farm.
But when I navigated to thsoe restored site pages, it gave me "resource not found /file not found " error.
I had deployed the custom web parts as a custom wsp and added into those site pages.
and it failed to load those web parts UI.
I was not sute whether this happened because of backup or restore from source spfarm to the targeted sp farm .

SX20 and SX10 best practices for small conference rooms using built in Display Speakers

Hi,
Im planning to deploy some small meeting rooms using SX10 and SX20 codecs, I was wondering if someone could give me some key points to consider:
1. Display recommendation, nice built in speakers, low delay (goog performance with codec echo canceller) I wish to use a 60 - 70 inch Led TV (not yet defined which brand and model) I would like to receive some feedback about nice performance displays with nice audio and echo cancellation performance based on your experience.
2. What would be the drawbacks of using SX10 and SX20 in larger meeting rooms maybe 10 or 12 people?
3. When to use external microphone? or when is recommended to use only internal microphone?
Thanks in advance for your help.
Best Regards, have a nice day!

Pretty well any modern display should work well - different people are going to have different ideas about whether the speakers are any good or not, so you'll have to listen to a few yourself and make up your mid what you think is "better". The echo cancellation can be tweaked manually on the codec to suit the display if required (rather than leaving it on the "auto" setting which, in our installations, has caused more troubles than it's worth).
The main drawback of using the SX10, or the cheaper of the range of the SX20s, is the camera and the amount of zoom. In a larger room, you're not going to get a good close up view with a 2.5x camera. I'd suggest for a bigger room, you look at the 12x cameras.
As a general rule - use additional microphone(s) when you can't get someone within a 3m radius one of the other microphones. So in a larger room, you may need many.

Best practice for credentials over the net?

I'm developing an AIR app which requests information about a
user's account from a webserver. Currently in the air app, I get
the user to input the same username and password they use on the
website. I md5 the password and send it to my server where I check
against an md5 password stored in a DB.
Is this secure enough? Is there a better way?
I was thinking about doing away with the password, and using
an application key, but that's an extra step for the user to hurdle
before using the app.
What are you guys and girls doing? How do all the twitter
apps authenticate on the webserver?

This method is as secure as the password: an attacker can see
the hashed value, and you must assume that they know what has been
hashed, with what algorithm. Therefore, the challenge in attacking
this system is simply to hash lots of passwords until you get one
that gives the same value. Rainbow tables may make this easier than

Best practice for hierarchical DTOs?

Hi!
Can someone tell me the best practice for hierarchical DTOs?
Use case: I've got a User object which holds one Folder object, which in turn holds a Set of Folder objects (children).
class User {
Folder rootFolder;
class Folder {
Set children;
}Normally, I'd fetch the user data with the help of a DAO from the database, copy the requested properties into a User-DTO, which will be transfered to the view. But what about the Folder objects?
Should I create a Folder-DTO class and copy each Folder property into the respective DTO object - in other words: rebuild the whole hierarchy? Or is there a better solution?
Thanks a lot!
Walter

So this is just a standard association.
How you handle it depends on usage.
As a guess perhaps you are thinking that you can only have one User DTO class. That isn't true. You can have several. For example one that contains the association and one that does not.
Or you have just one. And either it contains the association or you provide another mechanism that returns just the association given a specific instance of a User DTO (or some other identifier to the specific User.)

Best Practices for Removing Shots from BDMV folder

CS6 Production Premium Suite
Win7x64
Canon XA10
I would appreciate feedback on the best practices for the following situation:
Using Windows Explorer, I copy the BDMV folder from the XA10 to my Talk2 project folder.
The BDMV folder has three one hour shots (talks) where each shot is one hour called Talk1, Talk2, and Talk3.
Each shot consists of several MTS files in the STREAM folder since MTS files have a maximum file size so a new MTS file is created when a given MTS file reaches the maximum file size.
Since I only want to have Talk2 stuff in my Talk2 project folder, I need to remove the Talk1 and Talk3 stuff from the BDMV folder.
I delete the Talk1 and Talk3 MTS files from the STREAM folder.
I delete the Talk1 and Talk3 CPI files from the CLIPINF folder.
I leave the PLAYLIST folder as is.
Using the Media Browser, I import Talk2 (which consists of two MTS files).
I edit the clip.
This procedure seems to work, but I do not know if there are any "got you" issues.
Thanks in advance.

Oh, don't do it that way. I know a lot of people do, heck, my boss does, but it's just asking for trouble.
Treat your card as if it was your original tape master (because it is). It is the most important thing you have. Don't delete or move any part of it.
If you want to break up the talks, do it as you shoot them. Use separate cards for each talk and archive each one separately. There is too much valuable information in the structure of the card format. You may not need it now but your editing program may need it later.

Best Practice for ip helper-address

I have 2 dhcp servers on same subnet 192.168.1.0
I'm trying to setup my SVI
Gateway 192.168.6.1
How should the ip helper-address be setup?
ip helper-address 192.168.1.0
or
ip helper-address 192.168.1.1 <- dhcp 1
ip helper-address 192.168.1.2 <- dhcp 2
2 Dhcp servers setup each to handle half the scope of a given subnet.

Sparky
Generally I believe that the best practice for this is to use two helper address statements. This will send two unicaast packets, one to each server. The other alternative is to send a directed broadcast (which would actually be ip helper-address 192.168.1.255). To do this you would also have to be sure that ip directed-broadcast was enabled on the router interface connecting to the 192.168.1.0 subnet. Many people reguard ip directed-broadcast as a security vulnerability and do not want it enabled. If your environment is comfortable with enabling this function then both alternatives would work. The advantage of the directed broadcast is that it transmits one packet rather than transmitting two packets. If it were me I would use two helper address statements.

Best practice for importing non-"Premiere-ready" video files

Hello!
I work with internal clients that provide me with a variety of differnet video types (could be almost ANYTHYING, WMV, MP4, FLV). I of course ask for AVIs when possible, but unfortunately, I have no control over the type of file I'm given.
And, naturally, Premiere (just upgraded to CS5) has a hard time dealing with these files. Unpredictable, ranging from working fine to not working at all, and everything in between. Naturally, it's become a huge issue for turnaround time.
Is there a best practice for preparing files for editing in Premiere?
I've tried almost everything I can think of: converting the file(s) to .AVIs using a variety of programs/methods. Most recently, I tried creating a Watch Folder in Adobe Media Encoder and setting it for AVI with the proper aspect ratio. It makes sense to me that that should work:using an Adobe product to render the file into something Premiere can work with.
However, when I imported the resulting AVI into Premiere, it gave me the Red Line of Un-renderness (that is the technical term, right?), and had the same sync issue I experienced when I brought it in as a WMV.
Given our environment, I'm completely fine with adding render time to the front-end of projects, but it has to work. I want files that Premiere likes.
THANK YOU in advance for any advice you can give!
-- Dave

I use an older conversion program (my PrPro has a much older internal AME, unlike yours), DigitalMedia Converter 2.7. It is shareware, and has been replaced by Deskshare with newer versions, but my old one works fine. I have not tried the newer versions yet. One thing that I like about this converter is that it ONLY uses System CODEC's, and does not install its own, like a few others. This DOES mean that if I get footage with an oddball CODEC, I need to go get it, and install it on the System.
I can batch process AV files of most types/CODEC's, and convert to DV-AVI Type II w/ 48KHz 16-bit PCM/WAV Audio and at 29.97 FPS (I am in NTSC land). So far, 99% of the resultant converted files have been perfect, whether from DivX, WMV, MPEG-2, or almost any other format/CODEC. If there is any OOS, my experience has been that it will be static, so I just have to adjust the sync offset by a few frames, and that takes care of things.
In a few instances, the PAR flag has been missed (Standard 4:3 vs Widescreen 16:9), but Interpret Footage has solved those few issues.
Only oddity that I have observed (mostly with DivX, or WMV's) is that occasionally, PrPro cannot get the file's Duration correct. I found that if I Import those problem files into PrElements, and then just do an Export, to the same exact specs., that resulting file (seems to be 100% identical, but something has to be different - maybe in the header info?) Imports perfectly into PrPro. This happens rarely, and I have the workaround, though it is one more step for those. I have yet to figure out why one very similar file will convert with the Duration info perfect, and then a companion file will not. Nor have I figured out exactly what is different, after running through PrE. Every theory that I have developed has been shot down by my experiences. A mystery still.
AME works well for most, as a converter, though there are just CODEC's, that Adobe programs do not like, such as DivX and Xvid. I doubt that any Adobe program will handle those suckers easily, if at all.
Good luck,
Hunt

Best Practices for Using Photoshop (and Computing in General)

I've been seeing some threads that lead me to realize that not everyone knows the best practices for doing Photoshop on a computer, and in doing conscientious computing in general. I thought it might be a good idea for those of us with some exprience to contribute and discuss best practices for making the Photoshop and computing experience more reliable and enjoyable.
It'd be great if everyone would contribute their ideas, and especially their personal experience.
Here are some of my thoughts on data integrity (this shouldn't be the only subject of this thread):
Consider paying more for good hardware. Computers have almost become commodities, and price shopping abounds, but there are some areas where spending a few dollars more can be beneficial. For example, the difference in price between a top-of-the-line high performance enterprise class hard drive and the cheapest model around with, say, a 1 TB capacity is less than a hundred bucks! Disk drives do fail! They're not all created equal. What would it cost you in aggravation and time to lose your data? Imagine it happening at the worst possible time, because that's exactly when failures occur.
Use an Uninterruptable Power Supply (UPS). Unexpected power outages are TERRIBLE for both computer software and hardware. Lost files and burned out hardware are a possibility. A UPS that will power the computer and monitor can be found at the local high tech store and doesn't cost much. The modern ones will even communicate with the computer via USB to perform an orderly shutdown if the power failure goes on too long for the batteries to keep going. Again, how much is it worth to you to have a computer outage and loss of data?
Work locally, copy files elsewhere. Photoshop likes to be run on files on the local hard drive(s). If you are working in an environment where you have networking, rather than opening a file right off the network, then saving it back there, consider copying the file to your local hard drive then working on it there. This way an unexpected network outage or error won't cause you to lose work.
Never save over your original files. You may have a library of original images you have captured with your camera or created. Sometimes these are in formats that can be re-saved. If you're going to work on one of those files (e.g., to prepare it for some use, such as printing), and it's a file type that can be overwritten (e.g., JPEG), as soon as you open the file save the document in another location, e.g., in Photoshop .psd format.
Save your master files in several places. While you are working in Photoshop, especially if you've done a lot of work on one document, remember to save your work regularly, and you may want to save it in several different places (or copy the file after you have saved it to a backup folder, or save it in a version management system). Things can go wrong and it's nice to be able to go back to a prior saved version without losing too much work.
Make Backups. Back up your computer files, including your Photoshop work, ideally to external media. Windows now ships with a quite good backup system, and external USB drives with surprisingly high capacity (e.g., Western Digital MyBook) are very inexpensive. The external drives aren't that fast, but a backup you've set up to run late at night can finish by morning, and if/when you have a failure or loss of data. And if you're really concerned with backup integrity, you can unplug an external drive and take it to another location.
This stuff is kind of "motherhood and apple pie" but it's worth getting the word out I think.
Your ideas?

Our power outages here are usually only a few seconds; this should give my server about 20 or 25 minutes run-time.
I'm setting up the PowerChute software now to shut down the computer when 5 minutes of power is left. The load with the monitor sleeping is 171 watts.
This has surge protection and other nice features as well.

Best Practices for Team Collaboration using Adobe Captivate

With a team of 6 Instructional Designers, how can Adobe Captivate be approached where we can collaborate while producing e-learning material while maintaining a consistent look and feel of the e-learning we produce?
What are the best practices for a team of 6 IDs working and creating e-learning material in Captivate? Is there anything build-in that allows us to connect to the same libraries, templates, etc to share?
Please advise.
Thank you!
Susanne

Only some tips, never collaborated with someone else, being the solo teacher. You didn't mention which version you are using, what I write here is meant for CP7.
Be sure to prepare a theme and/or a template that will be used by everyone. A theme consists of master slides, object styles, skin editor. Master slides can have custom navigation shape buttons. In a template you can eventually also prepare different slides with placeholders, and eventually advanced actions etc. For CP6 and earlier that is the only way to reuse advanced actions, in Captivate 7 you can export shared actions that can be imported in any project for reuse.
A feature that few users know about are the external libraries. You can open the library of any project as an external library in another project. That is a good idea to store assets that you want to use in different projects: images, audio clips, video clips, eventually equations. The shared actions in a library can not (yet?) be used in another project however.
If you are on CP7 you have automatically the roundtripping with source Adobe Photoshop files and source Audition files, both from CC. That can also make collaboration lot easier if those assets are prepared in those applications. Will not expand on that, because I'm not sure you have the Creative Cloud applications.
Those are my two cents.
