Education Licensing - Basic Questions

Hi
I have some basic questions regarding licensing of student version of Adobe software (in UK).
1) If I purchase an education version of an application and install it on a mac can I transfer it to a replacment mac in the furture?
2) Can I upgrade it? For example, from Phtoshop CS4 to CS5 when it comes out?
3) When my education programme finishes can I upgrade to the full commercial version?
4) What are the limitations - upgrade, use of...etc - of the education versions?
Many thanks
GC

There's a FAQ that answers many of these questions and may be helpful to you. http://bit.ly/byG0p6

Educational License Questions

Okay, I know yet another post about the Education license is going to try some people's patience, but I keep encountering contradictory statements on forums and even from Adobe customer service. Plus, Adobe doesn't seem to have a web page where this is all spelled out in simple language. If they do, a link would be greatly appreciated.
These questions pertain to a U.S. resident (since I think the rules are different outside North America). I am not talking about the (cheaper) Student license as that does not allow commercial use. So here goes:
1. I assume that while you are still a student you can upgrade under the Education license. Are those upgrades less expensive than the corresponding commercial upgrade prices?
2. What are your upgrade options after you graduate? Can you upgrade to the new commercial version at the regular commercial upgrade price or do you have to buy the commercial version outright?
3. Related to the last question, what happens if you graduate still holding the Educational license and haven't upgraded - can you still use PS for commercial purposes after graduation under the Educational license?
4. What restrictions would there be on other members of the family that use the same computer as the license holder?
Thanks.

The student version does allow commercial use in the US.
1. I assume that while you are still a student you can upgrade under the Education license. Are those upgrades less expensive than the corresponding commercial upgrade prices?
You can upgrade the student version as well as the educational version. the upgrade prices are the same, there is no Educational upgrade. If you are a student or educator buying a new version will be the same cost as an upgrade or cheaper.
2. What are your upgrade options after you graduate? Can you upgrade to the new commercial version at the regular commercial upgrade price or do you have to buy the commercial version outright?
You upgrade just like anyone else.
3. Related to the last question, what happens if you graduate still holding the Educational license and haven't upgraded - can you still use PS for commercial purposes after graduation under the Educational license?
Student and Educational Licenses both allow commercial use. the difference is Students are only allowed one activation.
4. What restrictions would there be on other members of the family that use the same computer as the license holder?
Educational license allows two activations. Desktop, Laptop. this does not mean it can be shared by siblings (Bobby get one computer Billy gets another) and you can only use one activation at a time just like the regular version. You can however let your wife or childuse the computer if you are not using it.

EULA Educational License

Hi,
I was a final cut pro user but due to the new 'pro' 10 x version I am basically forced to change software,
So it's now between adobe and avid.
But I have a few questions I cannot get answered with regards to adobe, because they really do not have a customer service or anything do they...
So my questions:
- Am I allowed to use my educational license also for commercial projects?
- Am I allowed to keep using my educational license even when I graduate?
It's with regard to the production suite.
Dominick

Yes on both counts.

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

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.

Neophyte Asking Basic Questions

I must be thick - can't find answers to some really basic questions:
1. To distribute Compressor tasks, is Qmaster and Compressor required on all participating Macs?
2. Are they required to be exactly the same version across the participating Macs?
3. Are they required to have unique serial numbers? (I tried to start Compressor on a second Mac that had been installed from FCS 5.1 Crossgrade package that resides on original Mac - all that was on the second Mac was Compressor and Qmaster - Qmaster didn't seem to mind, but Compressor gave me a warning message and terminated....)
4. Assuming the above issues have been resolved as required, does Compressor have to be started on the "Services Only" Mac in order to assist in the processing?
Again, my apologies for the level of these questions....
Stan

1. Yes, plus, if you're sending Compressor tasks from Final Cut Pro, all computers in the cluster are required to have Final Cut.
2. It depends, but usually, yes, all versions need to be the same. Qmaster 2.0 and 2.1 are not compatible with each other. 2.0.1 and 2.0.2 would most likely work. together.
3. I've always been working with Volume Licenses here, so I can't verify this, but as far as I know Final Cut Studio programs won't operate if an identical serial number is operating on the same network. As far as recieving tasks, I'm not sure serial number checking is done.
4. The answer to this question can be found in the Distributed Processing Setup Manual (open Apple Qadministrator -> Help -> Distributed Processing Setup), but in a simple answer, no, a QuickCluster, Services and Controller, and Services only computer can all be configured into a cluster (I'm pretty sure).

Solaris10 basic questions PHP and MYSQL

Hi,
I am trying to learn something of Solaris because it this OS is used at my job, well, we have one system T2000 sunfire, it has Solaris10, we are trying to setup as local server to share some html files, and also we are trying to install some mysql databases, well we already setup Apache2 and it is working fine:
svcs -a | grep -i http
online Mar_10 svc:/network/http:apache2
Something that I don't know is if the server has already installed PHP and if it is running, I just found these files containing PHP:
./usr/local/php
./usr/local/php/doc/php
./usr/local/php/bin/php
./usr/local/php/include/php
./usr/local/php/lib/php
./usr/local/php/bin/php
# cd bin
# ls -l

-rwxr-xr-x 1 root bin 593 Jun 30 2005 phpextdist
-rwxr-xr-x 1 root bin 3068 Jun 30 2005 phpize
I was wondering if some of you can tell me if php is installed and running, I think it is not running because I created an php file and it doesn't work.
I also need to know if mysql is working or not, I think it is working, these are the process that I found of mysql:
/usr/bin/ps -ef |grep mysql
mysql 843 798 0 Feb 22 ? 40:59 /usr/local/mysql/libexec/mysqld basedir=/usr/local/mysql datadir=/export/ho

Thanks.

Thanks Alan bye the answer.

And I was thinking, before install another thing I want to be sure that php is not installed or running, I would like to ask some questions:
How can I know if php is installed?
How can I know if it is running? the way I have tried is placing a PHP file in the /var/apache2/htdocs and tried it from the browser, but it didn't work.
If PHP is installed how can I enable it or start it? and how to make it permanent or start automatically when server boot up?
What happen if i try to install the AMP, may I have to backup the files that we already have in /var/apache2/htdocs?
Will the amp cause troubles or conflict to the apache, perl and mysql that are already installed and running?
Another basic question and hope not to cause angry, is there inside Solaris any equivalent folder to "program files" like in win? it would be to have an idea of all the applications already installed in the system. or which is or are the folders in Solaris where I can see all the installed applications?
the last question the term "the box" is the term for machine, station, server?
Thanks.

Do educational licenses expire?

We have been using CS3 Photoshop, Acrobat and Illustrator for Mac for several years and now we get an error message that says the license has quit working. Do educational licenses expire?
OTOH, the error message also suggests uninstalling and reinstalling. Maybe it is not expired.
An Adobe readme says to deactivate before uninstalling. Since I can't open should I just go ahead and uninstall?

No.

Use educational license while changing schools for ~ 3 month.

I finished school in Germany, and this is basically my last month there. However I will start going to University in about 3 month. Do I have to be afraid, that my educational license might be canceled?

HI PeKayGe,
Your Educational License will stil work fine as you will be a student while stuyding in the University .We hope that the University you are going to join is in Germany only ?

Transfer Aperture 1.5 Education License

I purchased Aperture 1.5 in the first week of January for $150 with my first iMac purchase. I could not upgrade to Aperture 2 because it is an educational license. I want to transfer my Aperture 1.5 EDU license to either an educational institution or sell it at a reduced price to an individual. With Adobe, there is a form available to fill out to officially transfer the software license so that another individual or institution can register that software legally (it was PhotoShop CS that I re-sold).
Does Apple have a license transfer program like Adobe?

(Apologies, this doesn't answer your question....
Are you sure it is an educational edition that came with your iMac? I purchased a macbook pro in october and added aperture as pre-installed software at purchase time on the web site (This was an institutional educational purchase), and the media/license that came with my machine says 'APERTURE 1.5.1 RETAIL'
If you added this to your cart as a separate line item, you probably bought an educational copy, but if it was a preinstall on the machine, you may have the retail. (I don't know if aperture is available pre-installed on an iMac, this may only be an option on the pro stuff...Just checked, you can get logic/final cut express and iwork pre-installed on both, but not aperture (anymore))
Also, I have not yet tried to upgrade my license, but the media says retail, so I shouldn't have a hassle....

Frustration with obtaining educational license

I am wondering if anyone else is experiencing frustration
receiving the free Flex Builder license for students. I am a
student enrolled at a US college and have gone to the Adobe
Educational Store and clicked on the link for the free offer for
students. This takes me to the site www.flexregistration.com. In
there I have filled out the form four (4) times since November when
the offer started and provided my scanned copies of my tuition
bills and student ID card. I used the tuition bills to show that I
am a current student.
I have tried going through Adobe Customer Service multiple
times and each time I received a bland response telling me that I
had not placed a web order. This is not possible for this
promotion. I tried calling Adobe Customer Service three times only
to be patched through to operators in India whom I could barely
understand. Finally they gave up and sent me to Flex Builder tech
support, who of course told me they could not help me because I
"don't have the product". My last ditch was calling the Store
support, who told me that they could not help me as "their
computers were currently down".
I love all of what I am seeing Flex Builder currently do. I
just REALLY want to learn Flex Builder and show my classes that it
is the next great wave and I think what Adobe is offering is really
an amazing promotion. If I don't resolve this I will have to
continue my classes using the free version of Visual Studio Express
that Microsoft freely offers and continue learning .NET.
I think Adobe has great products, but when it comes to
encouraging learning in educational institutions, I question their
commitment, when I can not receive a coherent response from anyone
in the company. In this regard, Microsoft clearly has them beat.
I'm hoping someone in this forum from Adobe will read this
and resolve this issue or let me know how I can get it done.
Many thanks in advance.

Just liek the normal license - 2.

Four Basic Questions

I don't see a FAQ list for this area, so I'm going to ask questions that are fairly basic because I need help.
I am ready to turn a G4 tower into a server. I have reformatted the internal HD, bought two new SATA drives and a Firmtek SeriTek Serial ATA controller, so I feel pretty good from a hardware perspective.
The plan is to install the Mac OS X (Tiger) Server software onto the existing HD and use the two SATA drives for user files/data/storage. I believe this is possible, but have the following questions:
1. Can I partition the SATA drives (wanting to divide the 300GB drives into 4 75GB volumes) and still have the RAID work (assuming I partition each drive in the same way)? The manual seems to indicate each disk in a RAID must have a single partition, but I think I've read otherwise here and am confused on this.
2. If I can use multiple partitions, am I right in assuming that I need to create the partitions via Disk Utility BEFORE I install OS X Server?
3. And regardless of whether I can use partitions or not, the RAID is set up in the Mac OS X Server installation process, right? (Even when I am installing the software to a disk that will not be part of the RAID?)
4. Finally, (I have the 10 user license for the server software), are each of the partitions considered (in Apple terminology) a "share point"? In other words, if I do these four partitions, and someone logs into all four, will that use up 4 of the 10 licenses I have? I seriously hope not, but fear that it will. (Background, we have 6 employees, so I had the thought "10 users is plenty" ... but if 6 of the employees try to log in to three of the partitions each, is that 18 share points? That would seem to make the term "users" irrelevant.)
Thanks in advance for your help, I'd be grateful for insight here. I think I've done my research, but these basic questions are not ones I can seem to find answers to.
Patrick

1. Can I partition the SATA drives (wanting to divide
the 300GB drives into 4 75GB volumes) and still have
the RAID work (assuming I partition each drive in the
same way)?
I'm assuming you mean using Apple's software RAID to mirror the two SATA drives connected to your PCI card, right? If so, then you can just install the OS into the internal HD, and start up your new server. Then, launch disk utility, create the RAID mirror 'logical disk', and then (I think) you can create your multiple partitions on the RAID volume (not 100% sure it will let you, but that would be the process if it does). In any case, you might want to consider getting a PCI SATA controller that does hardware RAID itself - less strain on the server CPU, and generally more robust than software RAID. Also: you didn't say how big your SATA drives are, but they'd need to be 300 GB each to get a 300 GB RAID mirror volume, as a RAID mirror is half as big as the sum of it's members.
2. If I can use multiple partitions, am I right in
assuming that I need to create the partitions via
Disk Utility BEFORE I install OS X Server?
Since you're installing the OS on the internal drive which isn't part of the RAID, then no, you could install the OS first on the internal, then set up the RAID SATA disks later.
3. And regardless of whether I can use partitions or
not, the RAID is set up in the Mac OS X Server
installation process, right? (Even when I am
installing the software to a disk that will not be
part of the RAID?)
RAID is setup from the disk utility app, which you can do before or after you install the OS. Probably easier to do it after.
4. Finally, (I have the 10 user license for the
server software), are each of the partitions
considered (in Apple terminology) a "share point"?
No: partitions have nothing to do with sharepoints, and neither have anything to do with licensing. You can have 1 partition with 10 sharepoints inside it, or you could have 10 partitions with only one of them containing a sharepoint (note: be sure not to share a partition or volume: create a folder inside and share that instead). In either case, the 10 user license only restricts the number of users that can concurrently connect to the server (i.e. you can create more than 10 user accounts, but only 10 of them can log in at a time).

Basic question

Hello, i have a basic question. if i have defined 2 fields in a cube or a dso:
Name Quantity
and from the external flat file i get some characters for my quantity field. would my load fail? for standard dso and for write optimized?
NOTE: quantity field is a keyfigure defined as numeric.
and the load coming in has "VIKPATEL" for Quantity field and not numbers.
thanks

Hi Vik,
Yes, the load will fail.
May be you coud first load this data into BW (into PSA) and set both fields as characters fields. Then you can create DSO, do transformation from this PSA to the DSO, and put your logic as to what do you want to do with those Quantity that is not number (e.g. convert to 0, or 'Not assgined', etc).
You can use transfer rule, or a clean up ABAP code in the start routine.
Hope this helps.

Pl/sql vs sql basic question

Hi,
I have a very very basic question, so excuse me for that... I just would like to know the difference ( and the difference in usage) between sql and pl/sql?
thank you
Yann

SQL - the structured query language - is the language available for extracting data from the database. It is a 4GL, and each command stands alone and performs a database action.
PL/SQL is the 3GL primarily intended to control the flow of a series of SQL commands. PL/SQL does not, in any way, interact with the data in the database. It does, however, allow SQL statements to be called, or even created, in a specific order.
SQL is capable of a LOT more than people usually realize. Unfortunate, as people often create PL/SQL programs when single SQL statements will do the job. I encourage reading the O'Reilly 'Mastering Oracle SQL' book ... only after fiunishing that book do I recommend any of Feuerstein's excellent PL/SQL books.

Basic questions on data modeling

Hi experts,
I have some basic questions regarding data modeling within MDM. I understand the available table types and the concept of lookup fields. I know that the MDM data modeling concept is different to the relational concept. But having a strong database background my first step was to design a relational data model which I would like to transfer to a MDM repository. Unfortunately I didn't found good information material on this. So here are some questions maybe you can help me:
1) Is it the right approach to model n:m relationships with multivalued lookup fields? E.g. main table Users with lookup field from subtable SapAccounts (a user can have accounts in different SAP systems, that means more than one account).
2) Has a record always be unique in MDM repositories (e.g. should we use Auto ID's in every table or do we have to mark a combination of fields as unique)? Is a composite key of 2 or more fields represented with marking these fields as unique?
3) The concept of relationships in MDM is only based on relationships between single records (not valid for all records in a table)? Is it necessary to define all relationships similar to the relational data model in MDM? Is there something similar to referential integrity in MDM?
4) Is it possible to change the main table to a sub table later on if we realize that it has also to be used as a lookup table for another table (when extending the data model) or do we have to create a new repository from scratch?
Thank you for your answers.

Yes you are correct. It is almost difficult to map relational database to mdm one. But again MDM is not 'just' a database. It holds much more 'master' information as compared to any relational db.
1) Is it the right approach to model n:m relationships with multivalued lookup fields? E.g. main table Users with lookup field from subtable SapAccounts (a user can have accounts in different SAP systems, that means more than one account).
Yes Here you need to use MV look up tables or can also try Qualifier tables if it gets more complex
2) Has a record always be unique in MDM repositories (e.g. should we use Auto ID's in every table or do we have to mark a combination of fields as unique)? Is a composite key of 2 or more fields represented with marking these fields as unique?
Concept of uniqueness differs here that you also have something called Display Fields (DF). A combination of DF can also be treated as Unique one. For instance while importing records if you select these DF as a combination, you will eliminate any possible of duplicates based on this combination. Auto Id is one of the ways to have a unique id once record is within MDM. While you use UF or DF to eliminate any possible duplicates at import level
3) The concept of relationships in MDM is only based on relationships between single records (not valid for all records in a table)? Is it necessary to define all relationships similar to the relational data model in MDM? Is there something similar to referential integrity in MDM?
Hmm... good one. Referencial Integrity. What I assume you are talking is that if you have relationships between tables then removing a record will not be possible as it is a foreign key for some record. Here MDM does not allow that. As Relationships within MDM are physical and not conceptual. For instance material can have components. Now if material does not exist then any relationship to components is not worthwile to maintain. Hence relationshsip is eliminated. While in relational model relationships are more conceptual. Hence with MDM usage of lookups and main table you do not need to maintain these kind of relationships on your own.
4) Is it possible to change the main table to a sub table later on if we realize that it has also to be used as a lookup table for another table (when extending the data model) or do we have to create a new repository from scratch?
No. It is not possible to convert main table. There is only one main table and it cannot be changed.
I went for the same option but it did not work. What I suggest is to look up your legacy system one by one and see what fields in general can be classified as Master, Reference, Transactional - You will start getting answers immediately.

HT1311 I know this is a basic question, however, how do i change my pass word on itunes to stop my kids from automatically buying tunes from the I store... as my card details are already saved they just log in with their ipods and download via my account
