Basic questions about AirPort and channels

I have a VERY limited knowledge about networks. Please keep answers simple.
My setup is very basic. My computer is connected to the internet via AirPort through my wireless gateway (router).
When I pull down the AirPort menu from the toolbar it lists 3 network names plus Other. My network name is checked. Why are 2 others listed on my computer? They aren't listed in my AirPort Network System Preferences under Preferred Networks so I can't delete them.
I downloaded iStumbler to try to get more information. It lists all 3 names plus one more that comes on and off. My signal is over 100% and all the others are around 50%.
Also, three (including mine) are using channel 6 and one is using channel 1. Should I change my channel? Everyone always mentions 1, 6, and 11. Could I use 4 or 5? Are some channels stronger than others?
Thanks.

"...Why are 2 others listed on my computer?"
You have neighbors with wireless networks and you are getting a signal from them.
"They aren't listed in my AirPort Network System Preferences under Preferred Networks so I can't delete them."
You can't delete them because they are your neighbors signals.
"should I change my channel?"
I would switch to channel 9.

Basic question about storage and safety in iMovie '11

A very basic question about storage and safety:
I want to keep a backup of my raw footage on my external hard drive prior to begin working on the movie in iMovie. I want to do this:
1. Upload the digital files from my camcorder to my Desktop *(as opposed to iMovie)*
2. Duplicate that footage/clips.
3. Put the duplicate clips/footage into a folder labeled with the name of that footage (like "Fun At the Dentist" or "Jimmy Learns How to Yodel").
4. Drag the folder with the footage/clips into my external hard drive into a pre-existing folder titled "Backups/duplicates of all of my raw footage/clips." This big granddaddy folder will house all of the child folders of different movies.
5 Then, open up iMovie '11 and import the raw footage/clips from my Desktop rather than from my camcorder.
6. Then I want to make a duplicate of my finished movie and put it in my external hard drive in a "Finished Movies" folder.
I know that the original raw unedited footage will always be in iMovies '11 but I want the original to also exist immediately accessible in my external hard drive.
QUESTION:
Is this viable? Is it wise? (I know it goes an extra unnecessary step, but aside from that.)
*Do you have any precautionary advice?* Should I do something in my iMovies '11 preferences? What?
In earlier years with iMovie '04 or '06 (cannot recall) I made many novice errors and ended up losing audio to my finished movie. I also lost footage.
This time around with iMovie '11 I don't to make such novice, ignorant errors.
Thanks so much for any comments to this question.

Yes I'm sure it will work great for you.
The iFrame format is something Apple has come up with. The reason for its existence is unknown to me so I can only speculate. But it seems to me that Apple "invented" this format in order to have devices such as Ipod/Ipad/Iphone/Ixxx create clips that are editable on consumer hardware such as already mentioned devices but also standard Mac computers, without the need for format conversion.
iMovie converts most input formats during import, which takes a lot of time, and this need for conversion often comes as a surprise to most people new to home video editing.
iFrame has a resolution of 960x540 which is long way from the common standards of 1920x1080 and 1280x720. If your end target is YouTube however, this may not be too bad though. However if you intend to go with YouTube HD, you may find iFrame footage to look wrong since they are effectively upscaled to a higher resolution.
Technically iFrame uses the H.264 algorithm, a smaller frame size (960x540) and a rather low compression scheme. This will result in large files, but the plus side is that the files are ready for editing without the need for any conversion and iMovie will natively edit the files.

Basic Questions about Looping and Headers

Hello,
Relative SSRS newcomer here and I have a couple of foundational questions... These are based on the simple premise of the underlying dataset returning multiple rows of data, elements of each to be displayed on subsequent pages of the report.
Is it fair to day that the Table (or Matrix) are the basic elements used for an iterative report?
Assuming the above is true, I'm using a Table for my first experiment here.
I can iterate and display my records but I'm struggling with header and footer information.
I want to display header and footer information on each page the is part of the current record. I've tried to add these elements in the 'header row' of the table, but that doesn't seem to do it. I don't see any facility for a footer. Is
this to be accomplished with row groups or something?
Any guidance would be appreciated.

Hi Steven,
According to your description, you want to display interview questions and answers between interview name and date, and different interview name displays in different page. After testing the issue in my environment, we can use list to achieve your goal.
Please refer to the following steps:
Add a table to the design surface, drag question_name, question_answer fields from the Report Data pane to the table cells, and delete the last column of the table.
Click anywhere in a tablix data region, in the Grouping pane, Click Add Group, select Parent Group, in the Tablix Group dialog box, select interview_name, then click OK.
Right click [interview_name] next to details symbol, click insert row, select Inside Group – Below, then Inside Group – Above.
Delete the first row and the first column.
Merge all the cells in the first and last row, then drag interview_name to the first row and drag interview_date to the last row from the Report Data pane.
Add a List to the design surface, drag the tablix into the List.
Select and right click the List, in the Grouping pane, Click Group Properties, click Add button and select interview_name from the drop down list. Then click Page Breaks, and check Between each instance of a group check box, click OK.
The following screenshot is for your reference:
If you have any more questions, please feel free to ask.
Thanks,

Basic question about Actionscript and symbols

I like the object oriented features of actionscript (2.0).
One thing confuses me tho, namely the combination of symbol classes
and constructors. Since symbols can't be instanciated by new
SomeMovie(...), but rather has to be created with attachMovie(), it
seems to me that there is no use of constructors for symbols.
Instead you have to send an init object in the attachMovie() call.
This seems to me to be lacking in logic. It would be much more
logical if you could do:
var m = new MyMovie(constructor arguments...);
destinationClip.attachMovie(m);
Am I correct that this way of doing it is not possible in
current actionscript?
And second, don't you agree this would be a more consistent
use of the actionscript language?

First, I just wanna thank u for replying. I still have some
follow up questions that I think are of interest:
About the first issue of constructors u say they
automatically gets called. But isn't it true that only a
constructor that takes no arguments can be automatically called?
Because, how could a constructor call with arguments MyMovie(x, y,
size, etc), be automatically called? My point is, that it would be
more neat to send the parameters thru the constructor, than thru an
init object. Also, I wonder why u think constructors are error
prone. Maybe they are error prone exactly because
Flash/actionscript invites to an inconsistent way of initializing
MovieClips and other object instances?
Second, u say that attaching a class to a MovieClip should be
avoided unless all or most of the functionality of the MovieClip
Class is needed. I usually attach a class a MovieClip that needs
some code to describe its behaviour. In practice, I think the only
essential method that I need from MovieClip is the onEnterFrame().
Are you suggesting that it would be better to skip onEnterFrame in
individual objects, and rather loop over some array to make all
objects get their command to do their thing? I thought the good
thing about onEnterFrame was that I could avoid having to traverse
arrays of objects, and instead let Flash itself call all objects
that need to be updated each frame.
Third, I would like to repeat the benefit of not having to
create variable names as attachMovie requires. For instance, assume
alot of clips are being attached to the same containing clip. Now u
have to make sure that all attached clips get different variable
names, or strange things will happen. But if attachMovie just took
a reference to a clip as parameter u would avoid that problem.
If u know some document that discusses these issues, i would
be happy if anyone had a link to it. My suggestion to the Flash
developers is to make MovieClip objects consistent with ordinary
objects.

Exeedingly basic question about AirPort functionality . . .

Before I start digging into PDF manuals, I thought I'd ask if what I'm interested in is even possible. Thanks in advance for the information.
If I connect an external hard disk to my AirPort (via USB), obviously I can set it up to be accessible to any computer that connects to my network. I understand that. My question is, could I also access my hard disk from another internet connection? In other words, if I'm connected at Starbucks, and I need a file on my external HD, is it possible to set up the AirPort to allow me access (through some password-protected login, hopefully) via my Starbucks internet connection?
Again, thanks very much in advance for saving me the time of looking all this up.

Yes, you can.

Few basic questions about sharing and other stuff..

Hi there!
First of all I know where are "101" pages, but they are not giving detail information.
1.I know there are some folders where I can put files, web-sites and other in order to enable sharing.
What do I have to do to enable other users (from internet to)
- view my webpage when they enter my IP address in browser
- to access files which I want them to be able to acces (with user and password required)? I know there is sth like sharing, and windows sharing, but I give access to my all user folder, do I have to create new accounts on my mac?
2. It's kind of small problem, but can I run apps in finder using only keyboard (enter causes rename action)
3. Why doesn't safari keep addresses I used in addres field after few days?
The most important question is 1.
Will be gratefull for help.
Thanks
Adam Mscisz

1. Start Personal Web Sharing from the Sharing pane of System Preferences; if you have a router between your computer and the Internet, ports 80 and 443 need to be forwarded to your computer. You can set this up from the router's configuration page, which is accessible by finding the router address in the Network pane of System Preferences and putting it into a web browser. See this article for instructions on how to password protect your shared files.
2. You can use the Command and O keyboard shortcut to open the selected item in the Finder.
3. The default setting in Safari is to keep the history for 7 days. You can use the method posted by ptejad in this article to extend the time Safari remembers the history for. The method at the top of the linked page won't work in Tiger.

Basic questions about agilent34420a and drivers

Hi everybody! I have a few questions.
1) Сan anybody help me and tell where can find driver for Agilent34420A on RS232. On support CD which was together with the device i find only Agilent IO 15 and drivers for agilent 34401 (that in itself is strange)?
2) In certain source code (C#) i saw include one lib - "Ivi.Visa.Interop". Please, explain where it can be found?
3) There any emulators of working devices (agilent/keithley/other)?
Solved!
Go to Solution.

The IVI-C driver from NI is at

You'll have to check with keysight to see if they have a different one.

Basic questions about Objects and variables...

If I have the following:
Species theAnimal = new Species();
Am I right in saying that the object here is 'theAnimal'?.
If we just wrote it as:
Species theAnimal
Then i'm assuming that here 'theAnimal' is the variable name...right?
I'm just trying to get facts straight when reading.
Thanks for the help...
Yash

At first, theAnimal is pointing to one object, and
theMammoth is pointing to another?
In the final line, they're both pointing to the same
object. Isn't that kind of saying, they're pointing
to the same memory address/location?Yes.
They might actually hold the physical memory address of the object, or they might hold some other abstraction that the VM uses to locate the object. In either case, though, they both hold the same value, and you can picture that value as the address of the object.

Basic questions about warranty and AppleCare.

First, although folks in another forum have said otherwise, staff at the New York Apple Store, and a customer sales person on the phone, said that installing 3rd party RAM myself voided the warranty. Is this true?
Second--via a link from one of the posts below, I read that the AppleCare service extends for three years from whenever you purchase it; I had previously had the impression that, if you bought it after 11 months, you only got 2 years and 1 month of AppleCare. Which is true?
I got that from http://www.wiredbynature.org/comp/mac/macbook/mods.php

Hello,
First, although folks in another forum have said
otherwise, staff at the New York Apple Store, and a
customer sales person on the phone, said that
installing 3rd party RAM myself voided the warranty.
Is this true?
On some systems that require full disassembly, upgrading the memory can void your warranty. The Mac Mini comes to mind there. The Mac Mini's manual does not describe installing memory, and tells you not to service the machine at all.
But, the MacBook's manual does describe installing memory.
On page 79 of the MacBook's User's Guide, it says:
Adding Memory to Your
MacBook
4
This chapter provides information and instructions for installing additional memory and for removing and replacing the battery in your MacBook.
Warning: Apple recommends that you have an Apple-certified technician install memory. Consult the service and support information that came with your computer for instructions on how to contact Apple for service. If you attempt to install memory and damage your equipment, such damage is not covered by the limited warranty on your computer.
Then, on the following page, it describes the steps to install the memory modules along with pictures of the process.
Second--via a link from one of the posts below, I
read that the AppleCare service extends for three
years from whenever you purchase it; I had previously
had the impression that, if you bought it after 11
months, you only got 2 years and 1 month of
AppleCare. Which is true?
The AppleCare package extends your warranty coverage to a maximum of 3 years from the original date of the computer's purchase.
AppleCare must be purchased within the first year of the computer's warranty. It cannot be purchased after the 1-year warranty has expired (although Apple has occasionally permitted this when the warranty has only been expired for a day or so).
Information on AppleCare can be found here:
http://www.apple.com/support/products/proplan.html
Hope this helps.

Some basic question about SCM Installation

Hi Folks,
Could you please advice me about some basic questions about SCM and its installation -
Q1. Do I need to have an R/3 System to be able to practice OR demo the SCM system?
Q2. If, yes, which version of SCM is compatible with the ECC 5.0?
Q3. What are the basic requirements to install SCM (version compatible with ECC 5.0) and ECC on a oracle db and windows OS?
Q4. Does SCM have APO and BI as an inbuilt functionality OR does the user need to purchase these as an Add-On?
I know these are some basic questions, but these will help me give me a direction.
With best wishes,
Krishna

Hello Krishna -
Q1. Do I need to have an R/3 System to be able to practice OR demo the SCM system?
---> There are various Modules in SCM Like APO (Sub Modules DP (stand alone), SNP Needs Master data from R/3 and has to pass on transactional Data to R/3, PPDS same as SNP, GATP same as SNP), ICH needs Data from R/3 to work with. Core Interface (CIF) connects R/3 to APO for transferring data.
Q2. If, yes, which version of SCM is compatible with the ECC 5.0?
-->For thorough understanding explore the following links
http://help.sap.com/saphelp_scm41/helpdata/en/9b/954d3baf755b67e10000000a114084/frameset.htm

Q3. What are the basic requirements to install SCM (version compatible with ECC 5.0) and ECC on a oracle db and windows OS?
-->Refer Above
Q4. Does SCM have APO and BI as an inbuilt functionality OR does the user need to purchase these as an Add-On?
--> APO comes with a small BI inbuilt functionality. you can only perform certain functions using that BI.
Hope this helps.

Some basic questions on ESS and MSS

Hi Experts,
This is the first time I am going to deal with
ESS and MSS.
I have some basic questions about it and they are
listed below:
1. In an organization if they want to integrate
ESS and MSS, how do they go about? What I mean
is, will they install the packages in the R/3
system and then use the to portal features to
make iViews of ESS and MSS.
2. Or is there a seperate package for the portal
and the R/3 system
3.What is the best way to customize ESS and MSS
iViews? Is WebDynpro used to customize ESS and
MSS applications, if yes how?
4. Are these ESS and MSS packages different for
ECC and the older version of R/3 systems? If yes what are the major differences?
Please do let me know on these subjects and also
if anyone of you have any links or documents
associated with this scenario please do send me.
Thank you
Regards
Luke

Hi,
here is what I know..
1 & 2. Depending on the backend SAP version, the relevant ESS/MSS Business Packages have to be installed on the Portal. On the backend it will be via an Add-on.
3. The webDynpro versions of ESS/MSS are available from mySAP ERP2004/2005 (ECC5/6). The best way to customize the iViews would be through the NetWeaver DevStudio.
ent
4. Yes, the ESS/MSS packages are differ depending on the backend SAP version.
You can find all the different packages & their info right here on SDN. From the home page click on the Portal Content Portfolio on the right hand side of the page>Browse Content Portfolio>Self Service for ESS & Line Manager for MSS.

Here's a very basic question about 2 TB external drives and Time Machine.

Here's a very basic question about 2 TB external drives and Time Machine.
Ihave a Mac Pro with a .75 TB and 1 TB drive. It also has a 1 TB 2ndinternal drive. My current external drive is too small so I'll begetting a 1.5 TB or 2 TB drive.
Obviouslythe new larger 2 TB drive will backup everything on the Mac Prointernal drive with Time Machine. But there will be 1 TB of space leftover going to waste.
ShouldI partition the external drive so that the TM portion will be 1 TB andthe use the remaining extra partition for additional file backups withCarbon Copy?
Thanks for any insights.
I tried searching around on the new Apple discussion forum, but I find it much harder to use than the old forum I used to use.

The problem with terabyte drives is that that a 3 TB is about as big as you can get without going into RAID territory. Ideally, a Time Machine drive should be 3 times as large as all the drives you are backing up. So, if you have 2.75 TB of internal storage, you should have 8 TB of Time Machine space.
Of course, that is "should". If your TB drives are mostly empty, then you can get away with something 3 times the size of your used disk space. Just remember that you are pushing it. Linc is right about Time Machine needing space to work.
It is unlikely that you have regular churn on 2.75 TB of disk. I suggest identifying which drives and folders have the most activity and excluding those drives and directories that don't change much. It would be better to archive the data that doesn't change often and keep it out of Time Machine. Then you may be able to get away with a 2 TB Time Machine drive.

Basic question about NR filter

Very basic question about the (perhaps oversimplified) interface of the noise reduction filter.
Does anyone know definitively whether the first "Strength" slider is a master control for the filter overall (i.e. it controls the power of all other sliders below it), or whether it only affects an individual parameter (such as what might be perceived as luminosity-based noise, rather than color noise)?
In other words, if Strength is set to zero, but Reduce Color Noise is set to 100%, does the color noise reduction effectively become zero or 100%?
Neither the Help Menu nor three of the aftermarket books I have definitively addresses this. There are further redundancies regarding this "Strength" slider when advanced mode is turned on: for instance, if Strength on the "front" panel is set to 0, but 9 on the individual channel panels, what is the effective strength?
Thanks in advance -

Basic questions about Infocube

Hi, everyone.
I got very basic questions about infocube data handling.
With infopackage, I extracted all the data about employees from R/3.
But there were some mistakes during inputting employee data, like positions,
so I just extracted those employees data once more.
Now I have two requests in infocube, where the first one has some wrong data.
Is there any solutions about this?
I might got it all wrong, so as beginner, any suggestions and explanations will
be grateful.

Hi,
You can manually delete the earlier request by going in the Manage option of the cube. select the request and click on delete icon at the bottom.
Other option is to make setting in the Infopackage to delete similar or overlapping request.
Data target tab --> 6th column Automatic loading / deletion of similar request. --> click on the blank icon --> you will get a pop-up --> select the radio button - "delete existing request" --> Select Conditions --> Infosource are same, datasource are same and source system are same, --> selections are "Same or More Comprehensive "
Assign points if useful

Basic Questions About Compiling Source

Hi!
I have some very basic questions about compiling source on 10.6. BTW, if the unix discussions still exist, they've hidden them pretty well, so I hope I'm in the right place for this!
First off, you simply cd to the source dir, wherever it may be - in my case ~/Downloads/source/ - and during the install process, everything will be installed in its proper dir, right?
How do you know which compiler to use? There seem to be several: make, gmake, gcc, g++, etc...
Once you do figure out which compiler to run, the process is supposed to go like this, right?
./configure
make (or whatever)
make install
But this doesn't always work for me. For instance, I'm trying to compile 'arm', but it doesn't seem to have a 'configure' script.
$ ls ~/Downloads/arm
ChangeLog
README
armrc.sample
setup.py
LICENSE
arm
install
/src
Maybe it's that 'setup.py' file? What are you supposed to do?
Of course, it's not only this one that's given me trouble. Sometimes the readme will say I have to edit a certain file for my system. Are there just a few standard changes you always make? Or is it...how can I put it...complicated? How do you find out what's needed in those cases?
OS 10.6.8
Xcode 3.2.4
Python 2.7

This is the place for UNIX discussions. If you have developer-related questions, there is a forum dedicated to that as well: Developer Forums
First off, you simply cd to the source dir, wherever it may be - in my case ~/Downloads/source/ - and during the install process, everything will be installed in its proper dir, right?
Yes. Hopefully the project you want to install follows standard conventions. If so, you can do "./configure", then "make", and finally "sudo make install" to install the software into "/usr/local".
How do you know which compiler to use? There seem to be several: make, gmake, gcc, g++, etc...
The make file will figure that stuff out.
Once you do figure out which compiler to run, the process is supposed to go like this, right?
./configure
make (or whatever)
make install
Yes, with the addition of "sudo" before "make install" because "/usr/local" is owned by root.
But this doesn't always work for me. For instance, I'm trying to compile 'arm', but it doesn't seem to have a 'configure' script.
$ ls ~/Downloads/arm

arm? You mean "arm (anonymizing relay monitor) - Terminal status monitor for Tor relays." You really don't want to be messing with that stuff. The only people involved with Tor that are trustworthy are US Navy intelligence who have their own uses for it. If you don't understand it as well as they do, best stay away.
