Can't compute difference between symbols in different segments.

I have just compiled PostgreSQL with Sun Studio 9 (version #8 used to work nicely).
When compiling spinlock code on my sparc machine I get an error ...
/opt/SUNWspro/prod/bin/fbe: "/tmp/yabeAAAsfaizn", line 277: error: can't compute difference between symbols in different segments
Failure in /opt/SUNWspro/prod/bin/fbe, status = 0x100
Fatal Error exec'ing /opt/SUNWspro/prod/bin/fbe
cc: acomp failed for s_lock.c
gmake[4]: *** [s_lock.o] Error 2
I have no idea what this means and even google doesn't know. I wanted to look at the temporary file but somehow this file is cleaned up when fbe terminates. I have not found a flag preventing the software from doing that.
Can anybody point me to some documentation?
How can I find the problem? This code works with gcc and sun studio 8 by the way ...

Sorry for the late response but I was out doing business.
Here is the compiler version we are using:
[postgres@unknown /]$ /opt/SUNWspro/bin/cc -V
cc: Sun C 5.6 2004/07/15
This is the latest Sun Studio shipped with Fire 120 boxes for Sparc.
[postgres@unknown /]$ uname -a
SunOS unknown 5.8 Generic_108528-29 sun4u sparc SUNW,UltraAX-i2
Building a test case is a bit hard because I don't know what this error means and where it happens (I cannot preserv the file causing the error).
What I am doing is building a recent version of PostgreSQL (ftp://ftp.postgresql.org/pub/latest/postgresql-8.0.0.tar.gz). I am not using any specific flags - here is my build script;
#!/bin/sh
LD_LIBRARY_PATH=/opt/sfw/lib:/usr/local/lib:$LD_LIBRARY_PATH
# PATH=/opt/SUNWspro/bin/:/opt/sfw/bin:$PATH:/usr/ccs/bin

The code producing the problem is related to spinlocks. s_lock.c contains platform specific code for various systems providing support for spinlocks (please refer to the tar archive I have sent you - s_lock.c is too long to post).
Here is what configure tells me (relevant lines):

By the way; there are only VERY few parts in PostgreSQLwhich are platform dependent - there is a very nice and very good abstraction layer which abstracts all this locking stuff - the problem happens in Sun specific code and ONLY with Sun CC (not with gcc).
Help is very much appreciated.

Difference between New G/L Segment and Profitability Segment

Dear friends,
Can somebody explain what is the difference between New G/L segment and Profitability segment.
Thanks, Prakash

Hi,
Segment in New G/L is puerly for external reporting purpose.A segment is a sub area of a company for which has separate financial data and which has expenses and losses.For this segment we need virtually complete balance sheet for external reporting purpose.
Profitability segment is for analysis of profit within the organisation.A Profitability segment is a combination of different characteristic for which we want to analyse sales revenue and cost.These characteristic can be any thing for example customer, product, sales organisation etc.
For example We want to analyse what is the total sales of product A for customer group B under the sales organisation XYZ. Here profitability segment = Product+customer group +sales organisation

What is the difference between a tablespace, a segment and an extent ?

What is the difference between a tablespace, a segment and an extent ? Please explain in layman terms since I'm a total newbie to Oracle.
Regards
Gony

Hi,
These are logical structure of database
1. Tablespace : A database is divided into logical storage units called tablespaces, which group related logical structures together. For example, tablespaces commonly group together all application objects to simplify some administrative operations.
2.Segments
Above extents, the level of logical database storage is a segment. A segment is a set of extents allocated for a certain logical structure. The following table describes the different types of segments.
Segment Description
Data segment
Each nonclustered table has a data segment. All table data is stored in the extents of the data segment.
For a partitioned table, each partition has a data segment.
Each cluster has a data segment. The data of every table in the cluster is stored in the cluster's data segment.
Index segment
Each index has an index segment that stores all of its data.
For a partitioned index, each partition has an index segment.
Temporary segment
Temporary segments are created by Oracle when a SQL statement needs a temporary work area to complete execution. When the statement finishes execution, the extents in the temporary segment are returned to the system for future use.
Rollback segment
If you are operating in automatic undo management mode, then the database server manages undo space using tablespaces. Oracle Corporation recommends that you use "Automatic Undo Management" management.
3. Extents
The next level of logical database space is an extent. An extent is a specific number of contiguous data blocks, obtained in a single allocation, used to store a specific type of information.

Difference between extent management and segment space management

Hello,
Could you tell me the difference between extent management and segment space management interms of datablocks?

After 10g, default tablespace is locally managed and with this creation, your segment's spaces are managed "automatically".
Automatic segment space management is onlyt avaliable to locally managed tablespaces.
The logic of the automatic segment space management is;
For instance, we have a rectangle cube which is totally empty (1 extent - 8 segments - 64 block in default). If we enter a new data to our table, data is stored inside this cube with it's information. (default 8k). If our data must be splitted, check row chaining for further information.
At this point, oracle decides which block is filled with the entered data. It automatically fills the emty blocks. You can use this only if your tablespace is locally managed and your segment space managemet is auto.
On the other hand,
If we create dictionary managed tablespace,
Data is stored in "dictionary" (tables in SYS schema). This is a bit slower than locally managed tablespaces. So filling the extents, segments and blocks will be slow too. You need to specify the PCTUSED, FREELISTS, FREELISTS GROUPS for the storage of the data. If segment space managent is auto, you don't need to define those values.
In summary, locally managed tablespaces with automatic segment space management is Oracle's maybe the most important feature. I am not using dictionary managed tablespaces and i advice don't use it either. In the end, this is an upgrade of using segment spaces much more faster, easier and reliable, trustable.
PS: You will need to check "High Water Mark" for automatic segment space management.

Difference between extent management and segment management

friends what is the basic difference between extent management and segment management,as we know that segment is a collection of extents then why is it necesassry to manage both??..and what is the need to do so?

saugat chatterjee wrote:

Blocks --> Extent --> Segment
Oracle block(also known as page) being the granular level where the data is stored. Extent is a collection of blocks.
When you specify extent management, you mean where the allocation/de-allocation of extents(group of blocks) will be managed (either in dictionary or using bitmaps).
When you specify segment space management, you mean that how the space inside a block will be managed. Extent management doesn't control space distribution inside block.

About Olympus EP-1: ¿ Why Lightroom can't show difference between 2 RAW photos with different ISO?

When I take RAW+JPG photos with my new Olympus PEN EP-1 which the unique difference is ISO and I import in Ligtroom:
- I can see difference between JPG photos.
- I can´t see any difference between RAW photos (In Olympus Master or Olympus Studio I can see difference). The problem is Ligtroom

There are two sides to your question. I. should Lightroom read all embedded
tags to a RAW file, and II. can it even technically do it.
The problem is that all of tags such as this exposure compensation one,
sharpening, picture styles, etc. are embedded in proprietary file formats
that the manufacturers will not disclose the structure off. Adobe (and every
other RAW converter out there that is not made by the camera manufacturer)
has to hack into the file format to figure it out, so question II can be
answered by "probably not" This is not Adobe's fault, but that of the camera
manufacturers not using a standard RAW format. Interestingly, for camera
manufacturers that use a standard format such as DNG (think LEICA for
example), a lot of camera settings actually translate into Lightroom
settings.
For question I, you have to figure out where you draw the line. Which
settings, on top of simply white balance (which Lightroom reads of course)
should the program read and use? Myself I think the program should display
the RAW data as accurately as possible. In the case of the "ISO bracketing"
that is not really ISO bracketing, the RAW data did not change at all. The
program should reflect this, if only to make the user realize that it is a
useless experiment and only a waste of card space. That said, it would be
nice if some settings translate, but that is made really hard due to the
proprietary file format.
>Would I expect Adobe implements how Olympus E-P1 works in next versions ?
I doubt it, but maybe somebody at Adobe is adventurous enough to reverse
engineer/hack your files to figure out where the compensation tag is stored,
so you never know.
This is however a very uncommon situation to encounter. Why would anyone
bother ISO bracketing if the camera doesn't ISO bracket at all! You're
better off just dialing in extra or less exposure in post. For me the
advantages of LR over typically glacial and badly written manufacturer
software is so large that small issues such as this do not begin to add up
to an argument to change workflow. In the end that's all personal of
course.

Is there a huge difference between the two different processors on the 13"

I'm trying to work out if is worth spending the extra $190 (AUS) on the 2.53 processor or if there really isn't much difference between it & the 2.26 processor?
My exceptional use might be using imovie & flicking between that & iphoto & itunes and possibly having firefox & mail & MS word running at the same time. But that would be exceptional use.
Normal use might be mail, firefox, iphoto or Adobe photoshop elements (System 9) and word running all at once.

It is a fair old jump from an eMac to a current MBP, sd and you will certainly appreciate the speed and RAM boost (though , of course, the decrease in RAM prices has meant that programmers are less circumspect about wasting the stuff than they were in the days when you eMac was made!)
Apple's prices on RAM and HD upgrades are much more realistic than they used to be, although you can still save a little if you buy the base configuration, upgrade yourself, and then sell the old drive and RAM. Both are regarded as "user upgradable" on the MBP. On the other hand, getting the official upgrade saves a lot of hassle, and prevents any possibility of warranty issues if you stuff something up in the process!
My own MBP13 is the "base model", with RAM increased to 4Gig. With 4 Gig on board it is a little faster than my older 20007 15" "santaRosa" MBP for most things. With 2 gig on board it was a little slower in the sort of areas you are interested in. It definitely needs the 4 Gig, I reckon. (Both are much, much, faster than my iMac G5).
Yes, your strategy makes pretty good sense to me. The processor speed difference is about 10% at best. In any situation where HD access etc is involved it is likely to be less. Compared to the eMac you are looking at increases of several hundred percent on most tasks. With more RAM, a bigger HD, and a current copy of Elements you'll still be a few dollars in front.

Is there any difference between the 2 different USB cords when syncing???

I know this may be a paranoid question to ask but I just wanted to make sure.
Is there any difference between the newer USB cords with the shorter plug (the end that goes into the iPhone) and the older ones with the bigger, square-shaped plugs that you can pinch on the sides to retract?
Is there a difference in transfer speed, syncing speed, or reliability, or build quality?
Just asking cuz the newer USB cord that came with my iPhone 3GS is getting frayed and so I'm using the older one instead.
Thanks to whoever helps.

No difference except, as you noted, you have to squeeze the older one to remove it. It's important that you do that so you don't damage it or the iPod.

That's about the only way. Many of the fakes are indistinguishable from genuine without taking them apart. See: https://www.youtube.com/watch?v=wi-b9k-0KfE Note that BOTH of the adapters in this video are fake. Yet the one on the left looks identical to the "real thing".

The difference between symbols in CS4 & CS5?!

Whenever I would break the link to a symbol in CS4, it would still stay in it's own group.
Now in CS5, it becomes it's own Sub/Layer?!? Not a fan. Is there any pref that I'm missing?
Also, whenever I hit the green light in the upper left stop light to make the window expand fully,
the window ALWAYS changes whenever I open a new/different document. I didn't have the issues in CS4.
Please help.

Group the instance before unlinking the symbol.

HT202213 how can i do sharing between devices with different IDs?

one of my kids has an ipod and an own apple ID and i would like to shara my own music with that device too.
i've tried logging it with my apple ID but got a message saying i would then not be able to share with my own devices for the next 90 days....??
i guess i'm doing something wrong.... appreciate any help!

Does he have his own computer to sync with. Is it separate from yours?
Then you could use Home Sharing to make sure both lots of content are the same on both machines.
He will have to authorise his machine with your Apple ID for any purchased music to be played
Store > Authorise this computer
Then set up Home Sharing
http://support.apple.com/kb/HT4620
When it is up and running you can import from 1 library to the other and then your son can sync whatever he wants from his own iTunes

Can't see difference between new posts and old ones.

Hi
This may sound like a silly question......but why I can't see new posts everything looks the same, no indication of new posts.
It's very silly not to be able to see new posts.

Agreed guys ! We risk to not answer to someone, because we don't see that the thread has been updated. Before it was very easy to do that, now it' quite difficult :-(

Assembler: subtracting symbols in different sections

Hello,
the x86(_64) assembler that comes with Sun Studio refuses to compute the difference between symbols in different sections with an error message: "Illegal subtraction - symbols from different sections".
Even if it makes sense to refuse such subtractions (is there a standard somewhere that says they are illegal? The ELF ABI maybe?), gnu tools accept them, so people start using them (apparently there can be some benefits), and the code fails to compile with Sun Studio. I know gcc regularly has such problems since around 2005, and the latest version of gmp also has this issue.
Is there a chance such subtractions may become legal in some not too distant future?

The GNU assembler manual says that a program cannot subtract
symbols from different sections. The text states
Subtraction. If the right argument is absolute, the result has the section of
the left argument. If both arguments are in the same section, the result is
absolute. You may not subtract arguments from different sections.
I wrote some trial programs that subtracted symbols from different sections.
The assembler accepted one of them, but most failed to assemble with error
messages such as
t.s: Assembler messages:
t.s:27: Error: can't resolve `a' {.data section} - `main' {.text section}
There is a reason to reject such expressions. There is no ELF relocation type
for such expressions.
The one program that succeeded in assembling produced the value zero for
the subtraction even though it should have been nonzero.
I ran my tests under SLES 10 SP2. I used the assembler in /usr/bin/as. It is
possible that other Linux distros would produce different results.

Difference between upgraded Mac Book Air and Macbook Pro

Hi All,
So I was recently gifted a MacBook Air with unexpected upgrades. Here are the specs:
1.7GHz Dual-Core Intel Core i7, Turbo Boost up to 3.3GHz
8GB 1600MHz LPDDR3 SDRAM
512GB PCIe-based Flash Storage
The MacBook Air ended up with a severe battery issue and The Mac Store okayed an exchange on it. Upon realizing I had such an upgraded Macbook Air I started looking at exchanging it for a Pro. The sales folks really didn't answer my questions thouroughly, though I did end up going for the pro, I just feel it's a more solid computer. I got the one with a solid state hard drive, a 2.6 GHZ i5 processer and 8 GB 1600MHz DDR3 of memory.
Today I came across the specs on that Air and realized how much the processor had been upgraded. I'm frustruated that none of the sales folks really went over that with me, they just told me the Pro was nicer.
But now looking at the differences, I'm wondering if that MacBook Air with all it's upgrades actually nicer?
I'm hoping folks on this forum can explain the differences between these specs, especially the processors and how I'd experience the difference.

You shouldn't do. I'm infamous at multitasking. I will have a video paused, watching a few different youtube videos, had a few projects in word open. The Macbook Air never missed a beat. THanks to the SSD. If you're looking for portability go with the Air.
When it comes to Photoshop, it woud really depend on what you're doing in it. The SSD and Processor in the Air would help you a lot. But if you're editing larger pictures you might notice a bit of slug.
I have a 13 Macbook Air 2011 1.7ghz, 4gb, 128gb SSD for reference .
