Pro's & Con's of using auto channel and power

I have a network with over 50 AP's on one floor. I have let the WiSM blade automatically set the channel and power of each AP. I am finding that the coverage cells are way overlapped and AP's with the same channel are to close to each other.
Would I be better of manually setting both channel and power? What are the pro's and cons of this?
Seth

the cons are that it wont be able to fill in for coverage holes if they appear....
RRM only works well when the AP deployment is dense enough. for example RRM wont be able to turn down the power of the ap's unless each ap is heard by 3others at a value of -67 to -70 (depending on the wlc code version)
otherwise they will run at full power which can be too hot.

Recommendations for Semi-Pro or Pro HD Video camera to use with fcp and Mac

Recommendations for Semi-Pro or Pro HD Video camera to use with fcpX and Mac with auto settings and ability to override, need to add external mic or 2. Am one person crew so needs to be easy to use.

And check out the Panasonic AG-AC90. Very good specs for a prosumer unit. Everything in the semi-pro area will involve trade offs for sure. Key thing is to study up enough to know what your needs are vs what trade off are involved in the various models. The ag-ac90 trade off (one of them) is diffraction limited sharpness.

Ipad will not turn on the screen is just black, using the hone and power buttom together does not fix it

my ipad screen is blue, using the home and power buttons together do not fix it.

If you can't reset it by holding the power and home buttons at the same time until you see the Apple logo, then releasing, connect it to your charger for at least 15 minutes then try resetting it again If it won't reset make an appointment with the Genius bar at a nearby Apple store to have it looked at.

Can I daisy chain two mac pros so that I'm using one monitor and keyboard

Can I use two mac pro's with one monitor, keyboard & mouse? The two different machines have two different operating systems (Snow Leopard / Lion). One machine is brand new and the other is 5 or 6 years old.
I want to use both machines in tandem so that I can leave something to render while I work on something else.

KVM is an answer -- maybe. I use one for two machines to share one of my monitors (a VGA) and my keyboard (the second older machine seems to have sleep problems if I share a usb mouse on the kvm however).
The trickiest part of choosing a kvm is trying to find one that can handle the video; one that can handle the required bandwidth, and the connections. If one computer uses, say DVI, and the other mini-displayport, then you need to figure out which kvm can handle that with one (or both) of the machines using adapter(s).
You said one of the machines is brand new. Then it probably has thunderbolt. So you would need a mini-displayport, dvi, or vga adapter depending on the monitor. That means the older machine will need a similar connection since whatever kvm you get will have the same kind of ports for both inputs and its output.
A wild card here (at least in my mind) is if the newer machine has thunderbolt. While a mini-displayport display can be plugged into a TB connection, it is not clear that such a thing will work through a kvm. That is unknown territory I think at this point.

TS1506 I have just got a Mac Book Pro after 30 years of using Msoft products and now find a (in my opinion) a piddling issue with attachments in Mail - Apple - just fix it.

After over forty years in IT I am actually a platform agnostic however I have come to expect some developmental maturity across all products, especially in generally ubiquitous apps such as email. I am using OS X 10.8.3 on a 2013 build Mac Book Pro and am very happy overall. Is Apple planning on fixing the various problems with Attachments in Mail or are they relying on third party fixes and workarounds?

My apologies if I have caused offence, not my intention. I was unable to view attachements but have since discovered an addon app which solves the problem very neatly. By way of explanation my frustration comes from Apple appearing to indulge in client lock in as do Microsoft - this practice was "invented" by IBM and only served to irritate clients and inspire excellent work arounds by third parties - much the same as I notice with Apple. I thought Apple would have outgrown this after the IIe vs BBC but I see this is not the case. I have recently upgraded to Mavericks and have no problems with Mail but am now unable to transfer material from Mac Pro to Ipod unless I use the icloud - something I do not want to do for a variety of reasons, not the least being able to transfer MY data without the use of an unsecured transition area. I am very happy with the quality of the Mac Pro but less than happy with the restrictive practices of Apple; I realise Microsoft have similar practises but they are not as completely disruptive to what are generally simple operations commonly required when using computers.
My thanks to all the others who reponded - this is my first foray into the world of forums and I will continue to learn the rules.

Any pro's & con's with using Torch & google chrome & sync everything?

Are there any problems anyone has encountered using Google Chrome/Torch?

Torch I see has a built-in Torrent software. Torrent software is inherantly insecure. I would only rely on software from known official sources of public domain and commercial software. If you must share programs with others, or other programs in private, setting up an FTP server via System Preferences -> Sharing and client like Cyberduck, is far safer, and won't slow you down. Torrent software and other P2P software is an opening for files that can be sent as trojan horses which you can open and do harm to your Mac. The Mac App Store is good. There are other download sites, but I hesitate to recommend them as they often have optimizers that actually slow you down. I do not recommend using any system optimizers. The only maintenance a Mac user needs is a backup plan.

How to use auto-increment and search option for MS Access DB

Dear All,
I have configured our invoice in Adobe Livecycle and connected it to MS Acess 2007 as per http://forms.stefcameron.com/2006/09/18/connecting-a-form-to-a-database/.
All is working fine, I can insert, retrieve data from DB to invoice and vice versa.
Now I want few things to be implemented on our invoice.
When ever I open our invoice, it populate the first entry from DB, Is it possible to populate the last entry ?
Auto increment invoice number from MS Access DB every time we open our invoice after save.
How to implement search option from DB for invoice number ?
Please let me know if someone can provide me help on my scenario, so that I can share more stuff related to invoice and DB.
Look forward to hearing soon from experts and other team members.
Thanks & Regards
Riyad...

As far as I know there is not any auto increment data type in Oracle. Instead of this you should create a sequence and get the next value of the sequence while creating a row in your table.
CREATE SEQUENCE Test_Sequence ;
CREATE TABLE Test_Table ( Id NUMBER , Foo VARCHAR2(4) ) ;
ALTER TABLE Test_Table ADD CONSTRAINT Test_Table_PK_Id PRIMARY KEY ( Id ) ;
INSERT INTO Test_Table ( Id , Information ) VALUES ( Test_Sequence.NEXTVAL , 'FOO' ) ;

Airport Extreme,I created a network named "net1" I also created a "guest network",I was having slow connection speeds from my airport extreme to my laptop(macbook pro OSX 10.6.8) I changed channels and created "net1(5 GHZ)" can I delete "net1" completely?

Can I delete a network I created and now want gone outta the router(airport extreme)? I'd like to broadcast only what I'm using or my guests are using. Can I delete all networks by resetting the router back to factory settings?
I also have this UPDATE "A newer version 5.6.1 of airport utility is available" it KEEPS opening when I open my Airport Utility APP, but when I click on it to UPDATE nothing happens, ever. Im already running 7.6.3
Any good help will be greatly appreciated and noted =) thank you

Sure.. a reset will surely do it.. a removal of the offending name will also do it.

Sure can.

Bit of confusion here.
Latest version of the airport utility for snow leopard is indeed 5.6.1
Open the airport utility, about .. and check what version you are running.
The very latest airport utility is 6.3 and only can be installed on Lion or Mountain Lion computers.
The firmware latest version is 7.6.3
which makes it all a bit confusing.

Using auto save and versions

Hello all. I am new to the Apple iMac. Love it! Just downloaded Lion and am curious about Versions and Autosave but cannot seem to find any info in the Help menu. Will Versions work on Office for Mac software (ie, Office for Mac Excel and Word)?

Open Pages, Preview or TextEdit as the previous poster said, then:
i. hover your cursor round the title bar to make the arrow/upside down triangle visible
ii. click that arrow to see the menu.
Of course, you'll need to have some versions of a file in order for Versions to do anything!

6-month old Mac Pro has already had a new logic board and power supply

At a cost of $400 in shipping and a one-month wait, my 5-month old Mac Pro got a new power supply and logic board
Now I keep getting kernel panics, runaway kernel_task in Activity Monitor, and corrupted boot drives
External Firewire drives work some of the time, and occasionally my USB devices dont work either
This computer is a nightmare - how do I begin to figure out if this is OS (10.6.4) or hardware related?
The extended AHT test reports that all is OK - as does an extended memory test using Applejack
Should I do firmware updates and re-install the 10.6.4 combo pack, or am I just wasting more of my time?
I've got 4 macs and this is the only one that works badly - I think Apple's OS updates are getting as bad as Windows updates

My first question is why you spent $400 to get a 5 month old system fixed. That should have been covered under the warranty. So someone ripped you off, or you left out some key details.
And if you had both the logic board and PSU replaced, did you ever stop to think that maybe the problem lies with the power coming into your house? It's not really the big power spikes or blackouts you need to worry about, since those are pretty rare. What you need to worry about are the small fluctuations in voltage that happen several hundred times a day, if not an hour. Sometimes there's not quite enough power, other times there's a little too much, and all of this takes a steady toll on the PSU. It will do what it can to try and feed the rest of the computer a steady diet of electricity, but sometimes a jolt will get past it and start damaging other components. It could even cause data corruption on your HDD.
If the PSU and logic board already went, who knows what damage it may have caused to anything else. It may just be taking longer to show up.
It might also be that whomever ripped you off to the tune of $400 simply traded you one defective logic board for another. Or maybe they don't really know how to protect against ESD. I once saw a repair shop where the techs smoked in the same room they did the repairs. Sadly, for every one good tech out there, there's probably at least 3 complete idiots. Kind of like auto mechanics.
And I never have problems with Windows or Apple updates. Seems like on Windows the majority of people who have problems with updates are either running some program designed to change the way Windows looks or messes with low level system files, or they have a malware infestation they were unaware of/oblivious to. Most of the people who have problems with Apple updates seem to be the same way. They're running some truly bizarre programs that mess with the system in ways programs were not intended to mess with the system. There's generally a reason OS vendors provide an API for developers. You deviate from that at your own peril.
