Best pattern to use for multithread in vi ?

Hi,
I need to create an app, which will communicate to 5x usb to serial converters at the same time.
App needs to detect individually when the USB device is connected, upon connection, send it a few commands, and wait for removal. This repeats when the next unit is connected.
This all needs to happen, 5 x in parralel
I am not sure what would be the besy approach to use?
The obvious would be 5 while loops, but I am sure there must be something better?
Thanks!

5 loops might be an over complication, you might consider a queued state machine architecture. Are these processes very time intensive?

Elements 7 - Best Preset to use for the Panasonic SDR-H40 Camcorder

Hi,
Can anyone tell me what would be the best preset to use for video created on the Panasonic SDR-H40? I'm just learning about the software, opened a project, using whatever settings were already there, and the video's audio sometimes stops mid-stream, so it's basically a silent movie.
I read that I might need to use a specific preset or create one of my own, but don't know how to actually go about it.
The choices under NTSC presets are AVCHD, DV or HDV. I've looked in the Camcorders manual and can't find how (or even if) that equates to the recording modes of XP (high picture quality), SP (normal) or LP (recording time prioritized) -
The videos I recorded were recorded in XP - Taking a guess at it, I don't think there's a relationship between these terms and the recording modes of the Camcorder and suspect that this camera only does DV. But if that's true I don't know if there are further adjustments I need to make (by creating a preset).
I was hoping that someone with the same camera or just solid general knowledge could shed some light on this.
Thanks!

The camcorder is a standard definintion camorder recording to a hard drive so you need to use the.... NTSC, "Hard disc, Flash Memory Camcorder", Standard 28KHz or Widescreen 48KHz dependant on whether you shot in widescreen.

What's the best flash to use for nighttime sports games?

What's the best flash to use for nighttime sporting events? I have a rebel XT and I'm pushing it to its limits trying to stop the action. I've tried a speedlite 430 but it didn't have a hook up for an external battery pack and I was told I'd need the extra power. Just tried the 580ex ll on Friday but at the 1/1 setting, it didn't flash for each frame in a burst, even with the external power. I should have backed it down to 1/4 but didn't know at the time. Any thought on a really good flash for night sports? Is the 580 a good choice?

JUst as Tim_S said. YOu will want a external battery pack. Unforatannly the 430 does not have the option to plug in a external battery pack so will want to pick up a 580 or one of the new 600 series.
Then you start looking at the battery packs. I recommend Quantum power packs

What is the best software to use for screen capture on a PC for use with FCPX?

What is the best software to use for screen capture on a PC (windows 7) for use with FCPX? I've tried Camtasia and camstudio however the avi files cannot be imported by FCPX and the mov files produced by these programs are shown as just black screens in FCPX.

I use to face this issue every now and then (as a freelancer) when I use to cut on FCP7.
if the material is DV and was captured using Sony VEGAS, Premiere or Edius, the footage generally worked fine. You'll find most people will tell you to convert it regardless, however I found no issues working with them.
A problem you'll definitely face is HDV material. Most PC editing software write HDV in their own codec, which can't be read in FCP.
The only thing I can think of is to try converting HDV meaterial to QuickTime using something like MPEG Streamclip, or something similar.
Good luck

Best program to use for the Website?

I am interested in redesigning the home page of site: https://www.txid.org what would be the best program to use for the design?

Kim,
You should use design tools you're most comfortable with. Before engaging on design, you need to find out more on technology running the site being redesigned and see if there are existing design and HTML templates for that technology. If there are and you can minimally brand existing templates to quickly have professionally looking site, that would be the best way forward. Do not start with design only to figure out later that it be cost-prohibitive to execute, work your way from the ground up - server/site technology, existing HTML/WordPress/Drupal (etc) templates for that technology, branding options for those templates.

What is the best browser to use for facebook?

What is the best browser to use for facebook?

Any browser is supposed to work, provided the rest of the infrastructure (Flash, Java) is up to date.
However, since FB is so prone to install/modify/alter its settings/cookies/environment, I prefer to keep mine sandboxed and access it only via a dedicated browser used for nothing else, thus minimizing the risk and exposure. For that, I use the Flock browser, purportedly optimized for social media: http://www.macupdate.com/app/mac/19719/flock

What is the best editor to use for JSP/Servlet?

Hello,
What is the best editor to use for JSP/Servlet database development.
I'm looking at Dreamweaver,Java Studio Creator.
I want some thing fairly easy to use that has database helper wizards like dreamweaver.
Thanks for the help.
Frank

Is it better to have a servlet do the database work and call it from JSP?No, it's better to have persistence objects do the database work. Servlets handle HTTP requests, and JSPs are HTML factories that should be pure view.
But there are lots of ways to do things. You just have to understand the tradeoffs when you decide.
I do not want to hammer out code, I want to learn the
best way to do things from experienced developers. Sorry, sounded like you just wanted to churn stuff.
"best way" can be subjective. In one app, "best" might be "delivered fastest". For another, "best" might be "most secure" or "most easily modified" or "best performing" or whatever. You won't get a "best" answer, only different choices. And they aren't always so easy to explain or execute.
I'd recommend that you start by reading about layered applications (3-tier architectures) and MVC separation. Once you've Googled enough about that, look into a framework like Struts or Spring or WebWork. That'll help you figure out where to put each responsibility in your app.
I can use dreamweaver to create web apps, but I hate
the arrays used to define fields. It also seems not
to take advantage of connection pooling.Don't know what you're talking about here, Frank. What do fields have to do with connection pooling?

What are the best settings to use for the newest AirPort Extreme (AC wifi) with my optimum online service provider?

I have the current generation of the AirPort Extreme and a handful of devices that utilize the new 5Ghz A/C frequency. My internet speeds were blazing fast when I had first set it up but lately it has been lagging terribly. I was told that changing my dhcp did help, which it did it seems like it might be back to its normal speeds but I just want to know what are the best settings to configure for the airport so that I can get the most out of my service on all my devices? I'm using a CAT 6 cable which does help, I have a guest wifi setup with a wifi password which I understand will slow it down a little. Can anyone just point me in the right direction or just give me a step by step guide on what settings to configure? Should I really consider turning off the guest network?

I am assuming that you are looking to configure your network to provide the highest level of bandwidth possible for your network clients. If that is the case, the following are a few things to consider:
The Internet modem should support Gigabit Ethernet. That is the Ethernet connection between the modem and your 802.11ac AirPort Extreme should be Gigabit Ethernet.
Use CAT-5e or CAT-6 Ethernet cables between all wired connections.
Only expect 802.11ac performance with 802.11ac clients in the same room as the base station.
Eliminate or significantly reduce any forms of Wi-Fi interference on both the 2.4 & 5 GHz bands.
When streaming, especially HD video on your local network, use wired connections between the host and player devices when possible.
Other than the above suggestions there are no "magic" settings that you can make on your AirPort. Note: The Guest network shares the same bandwidth as the "main" network. Unless you have a network goal to provide this type of network, it is best left disabled.

Personally, I prefer uncompressed TIFF or PNG. But many times it won't matter ... you'll be dropping the images into an SD Sequence, so they will lose resolution on output.

Best codec to use for NTSC

I have a 5 minute project that has been in and out of color as well as after effects and was wondering what codec setting would be the best to use for DVD. I'm only putting it through iDVD, just wanted to make sure that whatever I use doesn't take away from the quality, etc...
would it be fine just to use a straight export to a Quicktime movie using the project settings?
thanks everyone.

would it be fine just to use a straight export to a Quicktime movie using the project settings?
Yes. Do this.
DVD video always uses MPEG 2 video files as it's basis and iDVD does the encoding internally for you anyway. It is aimed at consumer users and intended to be foolproof.
Once you make the step up to DVD Studio Pro, then you will have to pay attention to the format. But there are DVD presets in Compressor that make it a relatively simple and painless procedure.

Best transitions to use for web video

My client would like more transitions to 'smooth' some edits for a web video. The transitions should be pretty traditional (no checkerboard) but the main choices that look ok seem to be wipe and slide. Dissolves don't really look right.
Any ideas on this? Best ones to use? plug-ins? Thanks.

For anyone that has a similar issue to the one listed here, when editing an interview down to a 5-minute piece with no b-roll or stills, I found that using transitions like luminance map, and QT gradient wipe are some good options - for web viewing.

I apologize for the woolly way.
