[SOLVED] How should I understand this ATI wiki?

Hello,
I'm trying to reduce my power consumption and found this article: https://wiki.archlinux.org/index.php/Ati#Powersaving
But I'm not sure how to understand this:
I enabled KMS.
First it says the power saving feature is disabled by default. Then it tells me I should use "sysfs" to change that. I don't have any application with that name, wikipedia tells me that its an virtual file system and there is no mention of "sysfs" anywhere in the wiki except this article. To confuse me even more, it tells me in the next passage that I should either use the sysfs interface that should be present by default because I use a recent version, or use the (unsupported) [radeon] repo.
Now I'm confused.
Also it doesn't mention how to check if it works correctly, so if anyone did this before, please tell me how I should understand this.
Thanks for your help

How should I understand the parameters/argument values in the {} and [] right after a function?

Hi,
How should I understand the parameters/argument values in the {} and [] right after a function?
For instance the {[Name="control"]}[Content] part in the
control=Excel.CurrentWorkbook(){[Name="control"]}[Content]
and also the [Control]{0} part in the periodctrl=control[Control]{0}.
Thanks.
Regards,

The "[]" operator in M is like the "." operator in C-like languages, if that helps. It takes an aggregate value with named components and it selects one of those components. In the case of the record "Foo", "Foo[Bar]"
returns the field named Bar. In the case of the table "Baz", "Baz[Quux]" returns the column named Quux.
Similarly, the "{}" operator in M does subscripting of lists -- like the "[]" operator in C-like languages. If "Foo" is a list, then "Foo{0}" returns the first element of the list, "Foo{1}" returns the second
element of the list, and so on.
In the case of tables, it's also possible to use "{}" with a record argument, in which case it will return the row which matches the record criteria -- provided there is exactly one. So if "Foo" is a table, then "Foo{[Bar = 1]}"
will return the row for which the Bar column has a value of 1.
Many of the data access functions in Power Query return what we call "navigation tables". Sql.Database, for instance, returns a table with columns named Name, Schema, Object, Kind and Data. Each table in the database has a single entry in this
navigation table. When we index into the table with "table{[Schema="dbo", Object="table"]}", we're selecting the single row that matches those criteria. This gives us a record. We then want to pick the "Data" field of
that record, which contains the actual table data. That's why there's typically a "[Data]" at the end of expressions which fetch data from the SQL table.

Turn off My PhotoStream in iCloud on both the iPad and the Mac. PhotoStream is what shares your photos (unless you are using iCloud Photo Library Beta, in which case, all photos uploaded are accessible from all devices signed onto the same Apple/iCloud ID).

Accidental damage is not covered under Apple warranty. And it seems there is much accidental damage. Only a Genius Bar tech looking at it can tell how much it will cost to repair.
Cost to repair will be high, I suspect (though Genius Bar will confirm/deny.
There is no gentle way to say this sir/ma'am ... someone will need to pay for your friend's MBA repairs.

There may be a defect in the phone. As you bought it in the US the only place you can get it looked at is in the US.
When you say you bought it new, unlocked did you buy it directly from an Apple store? If you did not it was hacked to unlock it, which could also be your problem. Apple stores are the only place in the US that sells legitimately unlocked iPhones.

HT1725 Some songs that I paid for fully downloaded, but it is only playing the small sample piece from the Itunes store. How should I fix this?

I had a Wish List with about 7 or 8 songs on there and I purchased them today. They all downloaded fine, except for 2. These two songs completed the download from what the computer says, but it will only play the short sample avaliable from the Itunes store. How should I fix this?

Other people have been having similar problems with songs over the last few days, I assume that there has been a problem with Apple's servers.
Depending upon what country that you are in (music can't be re-downloaded in all countries) then try deleting them from your iTunes library and redownload them via the Purchased link under Quick Links on the right-hand side of the iTunes store home page on your computer's iTunes : re-downloading.
If you aren't in a country where you can re-download music or if they re-download in the state then try the 'report a problem' link from your purchase history : log into your account on your computer's iTunes via Store > View My Account and you should then see a Purchase History section with a 'see all' link to the right of it ; click on that and you should see a list of your purchases ; find those songs and use the 'Report a Problem' link.

How should I do this...

I am creating a program that requires a few random numbers to be generated every second. How can I accomplish this? I have heard that activeobjects are capable of performing tasks at regular intervals, but I have yet to find a tutorial that explains how to use them.

Should I use an external hard drive to store the files while editing and how should I do this?

Getting used to FCPX and want help learning how to store my Canon D60 Video files on either my internal Mac book pro or on an external hard drive while editing projects?   Do the files need to be transcoded on the computer drive or can that happen on an external HD?
Thanks,
Greg

Well, in my opinion, it all comes down to speed. There are a lot of editors that swear that working with footage on your system drive will do all sorts of horrible things, cause crashes, etc. Really its a bunch a malarkey. The most it will do is slow you down when your system needs access to the drive. Bandwidth is bandwidth is bandwidth - its all the same. If working with video on your system drive caused crashes, so would doing thousands of other things and we would all have dumped apple long ago for Microsoft or linux.
Here's what I tend to get for sustained read speed on various drives (ie reading a few large files like video files):
USB 2.0: 25 - 30 MB/sec. Drive RPM doesn't matter much since USB is limiting factor, unless you're running a system.
Firewire 400: 28 - 34 MB/sec. Drive RPM doesn't matter much since FW is limiting factor
Firewire 800: 55 - 60 MB/sec. Drive RPM doesn't matter much since FW is limiting factor
internal drive on SATA II or III connection, or USB 3.0 external drive:
    7200 RPM: ~100 MB/sec
    5400 RPM (most laptop drives): probably ~70-80 MB/sec
SSD: 250-500 MB/sec if installed internally or over USB 3. USB 2 or firewire connection for an SSD is a waste of SSD speed *except* that they have fantasticly fast random access for reading many small files, so I got a really fast launching system in an experiment installing a system on an SSD and connecting it via FW 800 - but that's not relevant here
so - to make a short story long - do whatever works for you. avoid using USB 2.0 or firewire 400 drives if you're editing HD - you can't play transcoded ProRes 1080p footage from them reliably. And once you have more than one clip overlapping, like at cross dissolves, you're sunk. You're internal drive is likely much faster, even with the overhead of the system using it too.
Blackmagic Disk Speed Test on the app store is a good HD speed tester. Ignore all the video specific stuff at the bottom - its mostly for uncompressed video, which I doubt you're working with.
Since i have a recent macbook pro (late 2011) and my edits are usually not more dense than 3 layers of video at a time (mostly concert video rather than narrative film), I actually almost never transcode, or even render - and this is for 1080p HD video - because FCP X is so good at playing the imported original h.264 files. I store my media I'm working with on my internal laptop drive (which i upgraded to a 7200 RPM) or a FW 800 7200 RPM external drive.
h.264 files from the camera are much smaller than transcoded ProRes files, so they will play back from USB 2 or firewire 400 drives, but I would only do it in a pinch.
enjoy your editing.

How do you understand this Oracle Documentation

Hi,
Could you please tell me how you understand the last sentence of the following paragraph. Please read it more than once and analyze the exacte meaning of each word, what is the meaning of the BUT NOT and the OR:
You can skip all tablespaces in the target database except the SYSTEM tablespace, undo tablespaces, and tablespaces containing rollback segments. RMAN does not check for completeness. For example, you can duplicate a data tablespace but not the tablespace containing the index for the data, or duplicate a tablespace that contains only one partition of a partitioned table.
The entire document can be found under:
http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96565/rcmsynta27.htm

I think, there's an 'only' missing:
'you can duplicate a data tablespace but not only the tablespace containing the index for the data'.
It makes no sense to duplicate an index tablespace without the data tablespace it belongs to.
And if you have partioned tables belonging to different tablespaces, you have to duplicate ALL these tablespaces.

Hows should I do this?

Ok trying a bit of programming, first in ages...
Trying to make 2 classes, Player and GameTest. Ok, what i want to do is for a prompt to ask the user for firstname, secondname, nickname etc...you will see in the code.
This is player:
import java.io.* ;
class Player
    String line, firstName, secondName, nickName;
    int    age;
    char   sex;
    // constructor
    Player( String first, String last, String nick, int age, char sex )
       firstName = first ;
       secondName = last ;
       nickName = nick ;
    BufferedReader userIn =
        new BufferedReader(
        new InputStreamReader( System.in ) );
    System.out.println("Please enter your first name:" );
    firstName = userIn.readLine();
    System.out.println("Please enter your second name:" );
    secondName = userIn.readLine();
    System.out.println("Please enter your nickName:" );
    nickName = userIn.readLine();
    System.out.println("Please enter your age:" );
    line = userIn.readLine();
    age = Integer.parseInt( line );
    System.out.println("Are you male or female?:" );
    sex = userIn.readLine();
    //put in if m=male or f=female otherwise error
    void details()
          System.out.println( "Your details: " + firstName + secondName);//and all the rest....
}This is gameTest:
class GameTest
public static void main( String[] args )
    Player player1 = new Player(
        Andrew, Schofield, Sco, 22, M);
    System.out.println( "Your details: "
        + player1.details() );
}Now instead of me typing in my details into the code, i would like to be prompted on it, so do I need all the lines of code prompting in the player class, or the game test?
My overall idea is to have like a text based story game, you know with loads of decisions which effect the way the book turns out. I want those decisions to effect characteristics which the user enters at the start, so age will increase, nickname may change etc etc, all depending on decisions in the story. I may also need to add more than 1 player, so thats why i have the player class...
Could anyone modify my code so that it will do what I want, either that or give me some simple advice to follow, as I am kind of new to java.
Any help?
Sco

Ok I seem to be stuck now. have managed to creater a player object by having the details entered into the code. I dont know how to make it so that the user can input the details himself...well I kind of do. In one of the posts I showed above, I used the readline method, but I am not sure how to get thisinfo to go into the constructor in my test class. Sorry if this doesn't make sense... Here is what i have:
import java.io.*;
class Player
// instance variables
String firstName;   // First Name
String surName;     // Second name
String nickName;   // nick Name
int age;
String line;
// constructor
Player( String first, String sur, String nick, int age )
    firstName = first;
    surName   = sur;
    nickName = nick;
    this.age       = age;
BufferedReader userIn =
        new BufferedReader(
        new InputStreamReader( System.in ) );
// methods
String details()
    String result = "\nFirst Name: "+firstName+"\nSur Name: "+surName+"\nNickname: "+nickName;
    return result;
String names()
        System.out.println("Please enter your first name:" );
        firstName = userIn.readLine();
     System.out.println("Please enter your second name:" );
     surName = userIn.readLine();
     System.out.println("Please enter your nickName:" );
     nickName = userIn.readLine();
int age()
        System.out.println("Please enter your age:" );
        line = userIn.readLine();
     age = Integer.parseInt( line );
}Now I can make each of the attributes (ie the 3 names) into seperate methods if its going to be easier?
Now I want the info it stores to replace this line of code in PlayerTest.java
Player player = new Player( "Andy", "Schofield", "Sco", 22 ); That is what I am not too sure of. If you could help that would be great.
EDIT: Actually can i just replace "Andy" with firstName, "Sco" with nickName or will that not work? Also my age keeps on coming out as 0, do I need to do something there too?
Cheers
Andy
