-6.1db..........a magic number in logic?

hi, i find i use/choose this number in logic a lot.
-6.1db is to absolute peak i'll let any recorded trk to be rendered at.
-6.1db is rarely exceeded on any fader anywhere.
-6.1db is where i set the peak limit of a compression/limiting plug 90% of the time.
-6.1 to -18db is the range my faders move in the most.
-6.1 to 0db is the attenuation range i set most plugs to if they feature an input trim.
just above -6.1db (5.9) is where the peak in Wave Burner set as standard for burning cds. (i'll go to just under 0db for clients).
the numbers: -6.1, -12, -18, and even -24db are basic level settings/ranges
used in most of my mixing.
Magic number?
david r.

G'day, mate, these steps, i'll use as rough start
points to get a mix going, then i'll home in on fine
tuning down to +- 1.5db, and sometimes smaller.
i'm finding that my mix levels are more consistant
and predictable like this.
and with clients it reduces time/money.
i even have preset on the gain plug at these values.
it's getting to the point where i know the outcome of
a render without having to look at the resulting
file.
it is also invaluable training for one's ear to be
able to resolve minute change in level.
cheers, david r.
Well I do not believe in "magic" anything when it comes to audio but I think it is a very sensible approach to use a universal detente point and 6.1 sounds fine to me.

How to come up with a magic number for any table that returns more than 32KB?

I am in a unique situation where in I am trying to retrieve values from multiple tables and publish them as XML output. The problem is based on the condition a few tables could retrieve data more than 32KB and a few less than 32KB. Less than 32KB is not an issue as XML generation is smooth. The minute it reaches greater than 32KB it generates a run time error. Just wondering if there is any way to ensure that the minute the query's results is greater than 32 kb, it should break say - if the results is 35KB, then I should break that result into 32 KB and 3kb; once done then pass this data to be published as an XML output. This is again not just for one table, but all the tables that are called in the function.
Is there any way?? I am unable to get any ideas nor have I done anything so complex from production support stand point. Would appreciate if someone can guide me on this.
The way it is, is as follows:

                      || ' WHERE record_update_tms <= TO_DATE(''' || TO_CHAR(vLastPubTms, 'MM/DD/YYYY HH24:MI:SS') || ''', ''MM/DD/YYYY HH24:MI:SS'') ' ;
                     || ' AND rownum < 16'
The minute I comment
|| ' AND rownum < 16' ;
, it throws an error because this query returns around 600 rows and all of those rows need to be published as XML and the tragedy is that there is a C program in between as well i.e. C will call my packged functions and then will do all the processing. Once this is done will pass the results back to C program. So obviously C does not recognise CLOB and somewhere in the process I have to convert the CLOB to VARCHAR or instead of CLOB I have to use VARCHAR array as a return type. This is my challenge.
Anyone that can help me to find out the required magic number and also a brief know how, I would appreciate that. Many thanks in advance.

Not sure I understand which part is failing.
Is it the C program calling your packaged function? Or does the error occur in the PL/SQL code, in which case you should be able to pinpoint where it's wrong?
A few comments :
1) Using DOM to build XML out of relational data? What for? Use SQL/XML functions.
2) Giving sample data is usually great, but it's not useful here since we can't run your code. We're missing the base tables.
3) This is wrong :
vStrSqlQuery := 'SELECT * FROM ' || vTblName                     || ' WHERE record_update_tms <= TO_DATE(''' || TO_CHAR(vLastPubTms, 'MM/DD/YYYY HH24:MI:SS') || ''', ''MM/DD/YYYY HH24:MI:SS'') ' ;
A bind variable should be used here for the date.
4) This is wrong :
elmt_value := xmldom.createTextNode (doc, l_clob(1));
createTextNode does not support CLOB so it will fail as soon as the CLOB you're trying to pass exceeds 32k.
Maybe that's the problem you're referring to?
5) This is most wrong :
     l_clob(1):=REPLACE(l_clob(1),'<?xml version="1.0"?>', NULL);
     l_clob(1):=REPLACE(l_clob(1),'<', '<');
     l_clob(1):=REPLACE(l_clob(1),'>', '>');
I understand what you're trying to do but it's not the correct way.
You're trying to convert a text() node representing XML in escaped form back to XML content.
The problem is that there are other things to take care of besides just '<' and '>'.
If you want to insert an XML node into an existing document, treat that as an XML node, not as a string.
Anyway,
Anyone that can help me to find out the required magic number
That would be a bad idea. Fix what needs to be fixed.
And please clearly state which part is failing : the C program or the PL/SQL code?
I'd vote for PL/SQL, as pointed out in [4].

Bad magic number in super-block while trying to open /dev/sda2

hello,
So I've a linux partition, and then I wanted to install a Windows copy. I've only 1 HDD with differents partition into it:
sda5 (swap)
sda6 /user
sda7/var
sda8 / (which contain the boot and root of course)
sda3 /home
sda2 NTFS (windows xp)
So, as I had linux installed before windows, I had to make my sda2 NTFS (87) under my cfdisk. Then, I went to install windows, everything worked fine, windows booted with his boot system, but I had to restore grub with my archlinux live cd:
grub> find /boot/grub/stage1
grub>root (hd0,7)
grub>setup (hd0)
everything worked successfully, my grub loaded till while booting archlinux I got this error:
couldn't find ext2 superblock, trying backup blocks...
e2fsck: Bad magic number in super-block while trying to open /dev/sda2
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
What I tried is to run the e2fsck -b 8193 /dev/sda2 but right after that, I thought about it, this isn't linux partition so of course, the superblock isn't the same as they are ntfs type from widnows?
I've read on some forum but unfortunately didn't solve my problem, if anyone has any suggestion before I format the NTFS partition, I'd really appreciate it.
best regards, maz

what I think it happened, is that after installing windows your partitions numbers got twisted a bit. What you have to do is to edit /etc/fstab, and check out your linux and swap partitions mounting entries, I believe you just have to change the number of /dev/sda[number] coresponding to your linux partition in fstab
If you can't solve it, post the output of
fdisk -l
and
cat /etc/fstab

Is this a Bug? List Box do not scrollbar: Magic number 2461

In my case I am populating list box from database using script. I noticed strange behavior with List Box being populated more than 2461 list items. At run time List box do not display scrollbar if the list items are more than 2461. Looks like 2461 is the Magic number. I wonder if some one already noticed this behavior. I want to see the scrollbar irrespective of number of list items. In my case I need to load approximately 5000 list items. Any one has suggestions? Is it designed to behave like this or is this a Bug?
Thanks in Advance.
SekharN.

Hi,
I noticed it too !
I have several lists, some oh theme have more than 2460 items and don't have the scroll bar.
An other problem relative to scrollBar in listBox appeared : with Reader 8, i can't use the scroll bar (even if i have less than 2460 items); it appears but i can't scroll.
I see tthe french adobe team about these 2 problems next week. If we find something new, i'll tell you.

Increasing maximum number of Logical Processors in a Processor Group greater than the default (64)

Can the maximum number of Logical Processors allowed in a Processor Group be increased by Bcdedit command or registry key to a number greater than the default (64) to allow non-group-aware applications to seamlessly scale via multithreading across more cores
MSDN documents methods to reduce the max number of LP's in a Processor Group to 1 or any power of 2 less than 64 in order to increase the number of Processor Groups. But there is no discussion of how to increase the maximum number of Logical Processors
allowed in a Processor Group to a number greater than the default (64), e.g. to 128 or 256.
Since a non-group-aware application/process can only run on 1 Processor Group, increasing this limit is needed to allow non-group-aware multithreaded applications to scale seamlessly for parallel computation across more than 64 cores simultaneously on systems
with more than 64 cores (for example, a quad-socket Intel Xeon system with 24 cores per socket, including true and hyper cores). If that limit can be set via registry key or command line, or if there is another way to force all the cores on
all 4 sockets (4 NUMA nodes in this case) to join in 1 Processor Group, then non-group-aware applications will not need to be rewritten using group-aware thread-affinity APIs.

Hi John,
Are you trying to specify a static NUMA-node-to-group assignment, rather than letting Windows dynamically assign NUMA nodes to groups at boot time? If yes, You can refer the
following related KB:
How to manually configure K-Group assignment on multiprocessor machines
http://support.microsoft.com/kb/2506384
Systems with fewer than 64 logical processors always have a single group, Group 0. On systems with 64 or fewer processors, existing applications will operate correctly without
modification. Applications that do not call any functions that use processor affinity masks or processor numbers will operate correctly on all systems, regardless of the number of processors. To operate correctly on systems with more than 64 logical processors,
the following kinds of applications might require modification:
•Applications that manage, maintain, or display per-processor information for the entire system must be modified to support more than 64 logical processors. An example of
such an application is Windows Task Manager, which displays the workload of each processor in the system.
•Applications for which performance is critical and that can scale efficiently beyond 64 logical processors must be modified to run on such systems. For example, database
applications might benefit from modifications.
•If an application uses a DLL that has per-processor data structures, and the DLL has not been modified to support more than 64 logical processors, all threads in the application
that call functions exported by the DLL must be assigned to the same group.
By design, a non-NUMA computer is considered to have one NUMA node. Because NUMA nodes cannot span groups, the system creates a node for each group after you restart the computer.

Where can I find the serial number for LOGIC PRO from the AppStore

Please help me:
Where can I find the serial number for LOGIC PRO from the AppStore?
I bought and downloaded the application, now it asks me for the serial number but I didn't not receive it or can find it.

My understanding is that if it was purchased throught the App Store, then there is no requirement for a serial number. At which point does it ask you for the serial?

Bad magic number

I have an applet that i am trying to load in a JSP
<applet name="MyTestApplet" code="mypackage.MyTestApplet.class" >
</applet>
mypackage/MyTestApplet.class is under the approot/pages directory and the jsp is also in the same directory.
whenever the jsp is called and applet does not get inited and the error i see is a ClassFormatError: Bad magic number
Please help.. this is extremely urgent.
Thanks in advance for any input anyone may have.
The appserver i am using is SunONE

First the <applet tag is depreciated, you should use <object instead (w3c has depreciated applet for quite
some time now).
When I see the tag you don't use a jar package (archive is missing) so let's pretend the url to your page is
http://mysite/mypage.jsp
the mypage.jsp contains the applet so the url to the applet is:
http://mysite/mypackage/MyTestApplet.class
can you download the file using a browser?
you can do this by saving the following line in a html file and right click it then sava target
right click and save target as
After downloading is the file the same as the file on the web server?
The reason I ask this is because I got the bad magic number when a jar was loaded through a proxy.
The proxy did something with the jar file making it corrupt. I think your problem has something to do with
the way your web server is serving the applet or (proxy) something between the client and the server.

use -y and it fails with Fsck was running in yes mode. If you wish to run in yes mode using the alternate superblock run
fsck -y -o b=20350880 /dev/rdsk/c0d0s4
So then ran fsck via fsck -y -o -b=20350880 /dev/rdsk/c0d0s4
then I get Bad SuperBlock at 20350880: Magic number wrong.
Any help would be greatly appreciated.
Thanks Mark

So then ran fsck via fsck -y -o -b=20350880 /dev/rdsk/c0d0s4how about:
fsck -y -o -b=32 /dev/rdsk/c0d0s4
man newfs for the option to NOT create the filesystem but runs the command anyway and shows you the alternate boot blocks.

Magic Trackpad and Logic

Just wondering if anyone is using the magic trackpad with Logic. I was thinking of getting it; I love the multitouch gestures on my laptop. But I'm wondering what people's experience has been with the magic trackpad and Logic specifically. Any feedback would be greatly appreciated.

I have it... but have not updated to 10.6.4.
It does move the pointer around really well... as soon as Avid confirm use of 10.6.4 with Pro Tools (my main DAW) then I'll be able to use it for surround panning, etc...

Sun Ultra 25 - Bad magic number in disk label

I have a Sun Ultra 25 SPARC that is booting fine to it's 80GB SATA drive. Solaris 10, OpenBoot 4.22.19.
Here's what I did:
I installed a 2TB Western Digital SATA drive into the HDD1 slot.
I formatted the disk in the HDD1 slot via the format command, labeled the disk, and divided it into partitions.
I then used newfs to build the ufs on all partitions.
I mirrored the disk in HDD0 to the disk in HDD1 using ufsdump for all partitions. The data is accessible and looks ok.
After this was done I did an installboot to /dev/rdsk/c1t1d0s0 (the / partition of the HDD1 slot).
I then did a fsck on every partition to verify that they are okay.
I then took the hard drive in HDD1 and put it in the HDD0 slot, now wanting to boot off that disk.
At the reboot:
Bad magic number in disk label
Can't open disk label package
If I do a probe-scsi:
MPT Version 1.05, Firmware Version 1.08.03.00
Target 0
Unit 0 Disk ATA WDC WD20EADS-00R0A01 3907029168 Bocks, 2000 GB SATA device PhyNum 0
As far as I can tell disk0 is the correct devalias which is:
/pci@1e,600000/pci@0/pci@9/pci@0/scsi@1/disk@0,0
I just don't understand how the fsck is okay, but the boot give bad magic number in disk label?
The 80GB drive in HDD slot 0 works fine with the boot disk0 command, all I'm doing is swapping a larger disk with the same data for the smaller disk.

if it is like any other Sun product, it needs to go through the format command and get a volname.... it is just a label, but it needs to be done.

JVM issue with applet - Duplicate Key in Parameter Table - Bad Magic Number

Hey, I have Googled this one to death and have seen a few vague references to this problem, but nothing I can relate back as solution.
I wonder if I need to tell the customer to reinstall the OS and, ultimately, the JRE. I'm just looking for a little guidance on what any of you may think. Am I missing a setting or something?
The user is trying to download an applet with IE with 1.3.1_16 and Firefox 1.07 with the Java Embeded Plug-in.
Even though JRE 1.3.1_16, 1.4.2_09 and 1.5 are all installed and Firefox has the JEP also installed, Firefox still wants to use 1.3.1_16 as does IE. I'm guessing that the JEP didn't work.
They can't use Safari which does seem to be using 1.4.2_09 because their RSA ID won't authenticate through it.
On my machine, when I run with the same OS,browsers, and Java 2 plug-ins, I can successfully load the applet.
This is the error that the user gets in the java console is:
Duplicate key in parameter table: code using the htmlAttribute.
first: com.ibm.eNetwork.HOD.HostOnDemand
second: com.ibm.eNetwork.HOD.HostOnDemand.class
java.lang.ClassFormatError: com/ibm/eNetwork/HOD/HostOnDemand (Bad magic number) at java.lang.ClassLoader.defineClass0(NativeMethod)
at java.lang.ClassLoader.defineClass(ClassLoader.java:488)...
Would you reinstall the OS and Java? or look at another setting? or look at the JEP installation again?
Thank you.

Without reading the full post (sorry for that) my guess is that the applet needed to be fetched through a
proxy, the proxy corrupts the applet because it's signed (finjan is one that does that).
The reason why a proxy would do so is because the default settings of sun jre will ask the user the
"do you trust" question to the user which could result in the user loading an applet that is allowed to do
anything the programmer wants (4us, spyware, nasty stuff).
Try to do the following:
1. create a html file locally with the following content:
rightclick and save target as
2. open the page, right click the link and save the file
3. apen the file with an unzip programm (winzip) and check if the content has changed.
4. If the content has changed than the proxy might have done this, contact the system administrator
It might allso have been done by a firewall installed locally.

Thanks for any help.

This looks to be filesystem corruption. The reason the fsck's don't find anything is they are really _not_ doing any checking. In the filesystem is an unmounted-cleanly flag. This flag is set when the umount(1) is done. If the system were to crash with the filesystem still mounted, this unmounted-cleanly flag would not be set, so the system would consider the filesystem to need checking: no unmounted-cleanly flag, fsck has work to do; unmounted-cleanly flag set means fsck does nothing.
Be sure the filesystem is unmounted all around the cluster before attempting to repair the filesystem.
So do this:
    # fsck.ocfs2 -f /path/to/device/partition
The "-f" switch forces fsck.ocfs2 to ignore the state of the "unounted-cleanly" flag and actually perform its tests.
Does this repair the problem?
