Best practices for referencing external video across multiple computers

I have made a .swf that references an external .f4v . The swf plays fine on my own computer, but does not play on a colleagues computer, or another computer which we tested. The file is not for upload to web , it is for local playback. I assume this is a file path issue, but I have tried many different things including specifying a path and then recreating the same directory structure on the other computer. What am I missing? The f4v file can playback on the colleagues computer (I did install ffdshow , although another tested mp4 also plays back fine) but not the .swf. Please , any help would be greatly appreciated!
Thank you!

This could be a security context issue, is it possible on your own machine you have allowed access to that file or folder containing the F4V file, maybe using the global-security-settings in flash player? Have a read of the following just in case:

Best practices for sharing iPhoto libraries across multiple Macs

I have a pair of iMacs running 10.6.x. and iPhoto 11 connected via Ethernet to an Airport Extreme. I am looking for a way to share my iPhoto library between the two Macs.
I found an Apple Support note on the topic (http://support.apple.com/kb/HT1198) which states that a disk image is a supported location for a shared iPhoto library (with limitations acceptable to me) and it strikes me that this would be a way of hosting a shared iPhoto library onto a NAS device.
Am I missing a simpler solution or, more importantly, am I missing any blindingly obvious caveats? I'd love to hear from anybody who has tried this (successfully or otherwise) or anybody who has a better idea. I haven't bought a NAS device yet, so I'm open to alternative suggestions.
Specific requirements:
Members of my family use either one of a pair of iMacs.
The only user who edits the iPhoto library is me and I only need read/write access from one machine.
iPhoto library access limited to one user at a time is acceptable and practical in my case.

Easiest:
If the other users only get to see the Library then just use iPhoto Sharing.
Enable sharing in the iPhoto Preferences on the Host machine, then go to the other macgine and in the same location enable 'Look for Shared Libraries'
Other forms of sharing will give the users read/write access to the Library.
A strong warning: If you're trying to edit the Library (that is, make albums, move photos around, keyword, make books or slideshows etc.) or edit individual photos in it via Wireless be very careful. Dropouts are a common fact of wireless networking, and should one occur while the app is writing to the database then your Library will be damaged. Simply, I would not do this with my Libraries.

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 viewing home video on my Mac

Come on people - THERE HAS TO BE A BEST PRACTICE out there for storing and viewing family video!!
I'm the typical dad out there taking photos and video of my kids playing soccer, family trips ect ...
When I get home I hook my camera up to my MacMini (which is hooked up to my Plasma TV - and backed up to an external HD) and within mere seconds, my photos are nicely captured in iPhoto. Friends and family come over, I flip on the MacMini, select iPhoto (or Front Row) and we enjoy great slide shows.
I want to be able to have the same easy access to my videos -flip on my MacMini, start Front Row, view my various home movies, pick one and enjoy the show.
What is the best way to do this?
Current Technology
Canon HV20
iMovie 08
iPhoto 08
Front Row

Thanks for the welcome WC! And thanks for the initial help.
I have never exported video before (sad but true), so I have a couple "Workflow" questions for you or anyone else that knows this stuff
1) Should I assume I just hook my firewire up from my Canon to the MacMini and everything just starts to export?
2) Once exported into iMovie, I assume I can edit out some of the garbage (example - my wife sometimes forgets to turn off the camcorder and she'll video her leg or the ground for minutes at a time - I'd like to trash that.
3) Once edited, how do I move it into iTunes?
I will probably need to take an iMovie class ...

Best practice for TM on AEBS with multiple macs

Like many others, I just plugged a WD 1TB drive (mac ready) into the AEBS and started TM.
But in reading here and elsewhere I'm realizing that there might be a better way.
I'd like suggestions for best practices on how to setup the external drive.
The environment is...
...G4 Mac mini, 10.4 PPC - this is the system I'm moving from, it has all iPhotos, iTunes, and it being left untouched until I get all the TM/backup setup and tested. But it will got to 10.5 eventually.
...Intel iMac, 10.5 soon to be 10.6
...Intel Mac mini, 10.5, soon to be 10.6
...AEBS with (mac ready) WD-1TB usb attached drive.
What I'd like to do...
...use the one WD-1TB drive for all three backups, AND keep a copy of system and iLife DVD's to recover from.
From what I'm reading, I should have a separate partition for each mac's TM to backup to.
The first question is partitioning... disk utility see's my iMac's internal HD&DVD, but doesn't see the WD-1TB on the AEBS. (when TM is activity it will appear in disk utility, but when TM ends, it drops off the disk utility list).
I guess I have to connect it via USB to the iMac for the partitioning, right?
I've also read the benefits of keeping a copy of the install DVD's on the external drive... but this raises more questions.
How do I get an image of the install DVD onto the 1TB drive?
How do I do that? (install?, ISO image?, straight copy?)
And what about the 2nd disk (for iLife?) - same partition, a different one, ISO image, straight copy?
Can I actually boot from the external WD 1TB while it it connected to the AEBS, or do I have to temporarily plug it in via USB?
And if I have to boot the O/S from USB, once I load it and it wants to restore from the TM, do I leave it USB or move it to the AEBS? (I've heard the way the backups are created differ local vs network)>
I know its a lot of question but here are the two objectives...
1. Use TM in typical fashion, to recover the occasion deleted file.
2. The ability to perform a bare-metal point-in-time recovery (not always to the very last backup, but sometimes to a day or two before.)

Hi, and welcome to the forums.
You can, but you really only need a separate partition for the Mac that's backing-up directly. It won't have a Sparse Bundle, but a Backups.backupdb folder, and if you ever have or want to delete all of them (new Mac, certain hardware repairs, etc.) you can just erase the partition.
The first question is partitioning... disk utility see's my iMac's internal HD&DVD, but doesn't see the WD-1TB on the AEBS. (when TM is activity it will appear in disk utility, but when TM ends, it drops off the disk utility list).

Right.

Can I actually boot from the external WD 1TB while it it connected to the AEBS, or do I have to temporarily plug it in via USB?
I don't think so. I've never tried it, but even if it works, it will be very slow. So connect via F/W or USB (the PPC Mac probably can't boot from USB, but the Intels can).
And if I have to boot the O/S from USB, once I load it and it wants to restore from the TM, do I leave it USB or move it to the AEBS? (I've heard the way the backups are created differ local vs network)
That's actually two different questions. To do a full system restore, you don't load OSX at all, but you do need the Leopard Install disc, because it has the installer. See item #14 of the Frequently Asked Questions *User Tip* at the top of this forum.
If for some reason you do install OSX, then you can either "transfer" (as part of the installation) or "Migrate" (after restarting, via the Migration Assistant app in your Applications/Utilities folder) from your TM backups. See the *Erase, Install, & Migrate* section of the Glenn Carter - Restoring Your Entire System / Time Machine *User Tip* at the top of this forum.
In either case, If the backups were done wirelessly, you must transfer/migrate wirelessly (although you can speed it up by connecting via Ethernet).

Best Practice for re-usable forms in multiple Countries

Dear experts,
i'm seeking for suggestions about the best design which could help saving time on development for multiple forms i should produce for a multi-national client.
In more details, the client is asking to create a number of forms in the SD area (Order advice, delivery note/Bill of Lading, Payment slips and in particular Billing outputs) for different Countries in North and South America.
I'm striving to avoid creating separate forms for separate Countries, as ideally i'd want to create just one form per type (i.e. one form for Billing, one form for Delivery note...) and re-use the same forms for all Countries, where specific data should differ from one Country to the other.
We've been working on similar topics in the past, adding some logic behind some texts which we've made "parametric", meaning different standard texts are printed in the same box depending on some organizational values (i.e. sales organization or company code), but we're looking for something "smarter", where having different pricing structures in different Ctries, for instance, might still work if those Conutries use the same billing form
Is there any best practice you'd like to share with me with regards to this? Is there any new functionality SAP has delivered recently which helps in this direction?
Many thanks to all who will want to reply to my weird question.
Regards,
Fabio

Hi Scott.
Storing two columns of spatial data is fine in SQL Server. And you are correct that there is no built-in reprojection in SQL Server, most folks do that as part of data loading. There was talk of porting parts of ogr2ogr to SQLCLR, but I don't think anyone
did that.

What is the best practice for full browser video to achieve the highest quality?

I'd like to get your thoughts on the best way to deliver full-browser (scale to the size of the browser window) video. I'm skilled in the creation of the content but learning to make the most out of Flash CS5 and would love to hear what you would suggest.
Most of the tutorials I can find on full browser/scalable video are for earlier versions of Flash; what is the best practice today? Best resolution/format for the video?
If there is an Adobe guide to this I'm happy to eat humble pie if someone can redirect me to it; I'm using CS5 Production Premium.
I like the full screen video effect they have on the "Sounds of pertussis" web-site; this is exactly what I'm trying to create but I'm not sure what is the best way to approach it - any hints/tips you can offer would be great?
Thanks in advance!

Use the little squares over your video to mask the quality. Sounds of Pertussis is not full screen video, but rather full stage. Which is easier to work with since all the controls and other assets stay on screen. You set up your html file to allow full screen. Then bring in your video (netstream or flvPlayback component) and scale that to the full size of your stage (since in this case it's basically the background) . I made a quickie demo here. (The video is from a cheapo SD consumer camera, so pretty poor quality to start.)
In AS3 is would look something like
import flash.display.Loader;
import flash.net.URLRequest;
import flash.display.Bitmap;
import flash.display.BitmapData;
import flash.ui.Mouse;
import flash.events.Event;
import flash.events.MouseEvent;
import flash.display.StageDisplayState;
stage.align = StageAlign.TOP_LEFT;
stage.scaleMode = StageScaleMode.NO_SCALE;
// determine current stage size
var sw:int = int(stage.stageWidth);
var sh:int = int(stage.stageHeight);
// load video
var nc:NetConnection = new NetConnection();
nc.connect(null);
var ns:NetStream = new NetStream(nc);
var vid:Video = new Video(656, 480); // size off video
this.addChildAt(vid, 0);
vid.attachNetStream(ns);
//path to your video_file
ns.play("content/GS.f4v");
var netClient:Object = new Object();
ns.client = netClient;
// add listener for resizing of the stage so we can scale our assets
stage.addEventListener(Event.RESIZE, resizeHandler);
stage.dispatchEvent(new Event(Event.RESIZE));
function resizeHandler(e:Event = null):void
// determine current stage size
    var sw:int = stage.stageWidth;
    var sh:int = stage.stageHeight;
// scale video size depending on stage size
    vid.width = sw;
    vid.height = sh;
// Don't scale video smaller than certain size
    if (vid.height < 480)
    vid.height = 480;
    if (vid.width < 656)
    vid.width = 656;
// choose the smaller scale property (x or y) and match the other to it so the size is proportional;
    (vid.scaleX > vid.scaleY) ? vid.scaleY = vid.scaleX : vid.scaleX = vid.scaleY;
// add event listener for full screen button
fullScreenStage_mc.buttonMode = true;
fullScreenStage_mc.mouseChildren = false;
fullScreenStage_mc.addEventListener(MouseEvent.CLICK, goFullStage, false, 0, true);
function goFullStage(event:MouseEvent):void
    //vid.fullScreenTakeOver = false; // keeps flvPlayer component from becoming full screen if you use it instead
    if (stage.displayState == StageDisplayState.NORMAL)
        stage.displayState=StageDisplayState.FULL_SCREEN;
    else
        stage.displayState=StageDisplayState.NORMAL;

Best practice for sharing LOV's over multiple Application Definitions?

We want to define/generate (complex) LOV's in 1 place and use them in multiple sub-applications (different application definition files).
What is the best practive to accomplish this?
Frank

Frank,
Here is what you do:
- Generate the LOV the "normal" way using your first app def file
- In all other app def files, you create a "dummy" LOV group by the same name with the same items, so you can associate items with the LOV and specifiy return values
- For each "dummy" LOV group uncheck the checkboxes "Generate Pages", "Generate Page Definitions" and "Generate Controller Group". (only visible in expert mode)
- Make sure you first generate the first app def file before you run the [ages generated by other app def files.

Best practice for setting up iCloud with multiple devices using a single AppleID

Hi there
Me and my wife have an iPhone each, and are looking at getting both of us using iCloud. The problem is that we only use one Apple ID for our music library.
Is getting a separate Apple ID necessary for each device on iCloud, or can multiple devices have seperate settings/photos/music, etc.?

Using different Apple ID for iCloud is not necessary, but in most cases it is recommended.
You can however choose to use separate Apple IDs for iCloud and continue to use the same Apple ID for iTunes, thereby being able to share all your purchases of music, apps and books.

Best practice for code structure to control multiple devices in a 2 stage-sequence

I have a question about code architecture and getting multiple devices controlled and sychronized for one experiment. This is an "architecture"-type inquiry, so I am hoping for some suggestions on how to proceed.
I run an experiment in which I control 2 NI PCI-6733. I am soon to add a Tektronix AFG 3022B, and have long been putting off an opportunity to rewrite my labview code from the ground up. I inherited it from an earlier research, and while functional, I would like to make it easier to modify and break up into subVi's and such. Link to the current program (labview 8.6.1) is here if you would like to see the code that is currently used, and the subvi's are in a zip file. The current version of the experiment consists of just one stage, all the writing of the data to the PCI cards is saved for the end. I need to change this in my new setup though.
The new experiment consists of 2 stages. The first will run (looping an output array to the PCI cards) until it hears a "true" from another computer (connected via TCP). At that point, it should switch to stage 2 and run a sequence (usually 10^5 timeunits in length, where the time unit is 0.1 ms) that outputs to the two PCI cards, the AFG 3022B, and with the flexibility to add more devices in the future.
Most appreciated would be structural advice. How to arrange the VIs, if it's good to use a "master" VI that would control the two subVi's of stage 1 and 2, etc... Feel free to ask for more details if it would help clarify my question. Thanks!
Solved!
Go to Solution.

Programs of this type usually use a state machine of some sort. You can find many tutorials on LabVIEW state machines in these forums or the LAVA forums. If you are doing a rewrite, I would also recommend you consider LabVIEW classes. They help modularize your code and make the subparts more reuseable. You may end up with less to maintain, as a result.
<shamelessPlug>You may also want to consider TestStand. It was designed to run sequences of tests, so may make your life easier. It could also be gross overkill.</shamelessPlug>
Let us know if you run into issues with state machines or classes.

Best practices for firewall external interface addressing

Hi all,
Can anyone explain what is more secure when addressing the outside interface of a firewall in a network diagram?
1st option:
                          ISP router:
                               interface 1 (connected to the internet).
                               interface 2 to the firewall with public ip address.
                           Firewall:
                               interface 1 (connected to the router): public ip address
                               interface 2 (connected to internal network): private ip address (RFC1918)
2nd option:
                         ISP router:
                              interface 2 (connected to the internet (ISP)).
                              interface 1 to the firewall with private ip address (RFC1918).
                         Firewall:
                             outside interface 2 (connected to the router): private ip address (RFC1918)
                             inside interface 1 (connected to internal network): private ip address (RFC1918)
Any response is welcome.

It's not so much what is more secure as where you want to do the NAT and how may public IPs you have.
So if you only has a small block of public IPs and you wanted to use them for NAT on the firewall then you could use a private link between the ISP router and the firewall.
Usually though an ISP gives you two blocks, a /30 for the point to point link and then a larger subnet for actual use on the firewall.
For a single ISP setup doing the NAT on the firewall is usually the way it is done especially if you are using VPNs as if you NAT on the router it can interfere with the VPN.
If you end up with multiple ISPs then you may need to move some or all of the NAT configuration to the routers although it is not always necessary and you may still do it on the firewall. It depends on a lot of other things such as IP addressing, ISP advertisement of public IPs etc.

Best Practice for Storing Spatial Data in Multiple Projections?

From what I've been able to determine MS SQL can't do reprojections is that correct? Assuming it is, the state of Washington requires that our GIS data be managed in Washington Stat Plane South
but for our web mapping sites need the data in Web Mercator. Is it OK then to have two geometry columns in a spatial enabled table, say a county table, one in WSPS and the other in WM?
I’m coming at this from a 30 year background in GIS using ESRI software.
Usually we would store the shape / geometry in one projection and project it to other on the fly when needed.
That way there is only one definitive source. I don’t see a way to do this in MS SQL.

Hi Scott.
Storing two columns of spatial data is fine in SQL Server. And you are correct that there is no built-in reprojection in SQL Server, most folks do that as part of data loading. There was talk of porting parts of ogr2ogr to SQLCLR, but I don't think anyone

Best practice for test reports location -multiple installers

Hi,
What is recommended best practice for saving test reports with multiple installers of different applications:
For example, if I have 3 different teststand installers: Installer1, Installer2 and Installer3 and I want to save test reports of each installer at:
1. C:\Reports\Installer1\TestReportfilename
2. C:\Reports\Installer2\TestReportfilename
3. C:\Reports\Installer3\TestReportfilename
How could I do this programatically as to have all reports at the proper folder when teststand installers are deployed to a test PC?
Thanks,
Frank

There's no recommended best practice for what you're suggesting. The example here shows how to programmatically modify a report path. And, this Knowledge Base describes how you can change a report's filepath based on test results.

Best practice for distributing/releasing J2EE applications.

Hi All,
We are developing a J2EE application and would like some information on the best
practices to be followed for distributing/releasing J2EE applications, in general.
In particular, the dilemma we have is centered around the generation of stub, skeleton
and additional classes for the application.
Most App. Servers can generate the required classes while deploying the EJBs in the
application i.e. at install time. While some ( BEA Weblogic and IBM Websphere are
two that we are aware of ) allow these classes to be generated before the installation
time and the .ear file containing the additional classes is the one that is uploaded.
For instance, say we have assembled the application "myapp.ear" . There are two ways
in which the classes can be generated. The first is using 'ejbc' ( assume we are
using BEA Weblogic ), which generates the stub, skeleton and additional classes for
the application and returns the file, say, "Deployable_myapp.ear" containing all
the necessary classes and files. This file is the one that is then installed. The
other option is to install the file "myapp.ear" and let the Weblogic App. server
itself, generate the required classes at the installation time.
If the first way, of 'pre-generating' the stubs is followed, does it require us to
separately generate the stubs for each versions of the App. Server that we support
? i.e. if we generate a deployable file having the required classes using the 'ejbc'
of Weblogic Ver5.1, can the same file be installed on Weblogic Ver6.1 or do we
have to generate a separate file?
If the second method, of 'install-time-generation' of stubs is used, what is the
nature/magnitude of the risk that we are taking in terms of the failure of the installation
Any links to useful resources as well as comments/suggestions will be appreciated.
TIA

Aasif

Its much easier to distribute schema/data from an older version to a newer one than the other way around. Nearly all SQL Server deployment features supports database version upgrade, and these include the "Copy Database" wizard, BACKUP/RESTORE,
detach/attach, script generation, Microsoft Sync framework, and a few others.
EVEN if you just want to distribute schemas, you may want to distribute the entire database, and then truncate the tables to purge data.
Backing up and restoring your database is by far the most RELIABLE method of distributing it, but it may not be pratical in some cases because you'll need to generate a new backup every time a schema change occurs, but not if you already have an automated
backup/maintenance routine in your environment.
As an alternative, you can Copy Database functionality in SSMS, although it may present itself unstable in some situations, specially if you are distributing across multiple subnets and/or domains. It will also require you to purge data if/when applicable.
Another option is to detach your database, copy its files, and then attach them in both the source and destination instances. It will generate downtime for your detached databases, so there are better methods for distribution available.
And then there is the previously mentioned method of generating scripts for schema, and then using an INSERT statement or the import data wizard available in SSMS (which is very practical and implements a SSIS package internally that can be saved for repeated
executions). Works fine, not as practical as the other options, but is the best way for distributing databases when their version is being downgraded.
With all this said, there is no "best practice" for this. There are multiple features, each offering their own advantages and downfalls which allow them to align to different business requirements.
