E66.... wrong choice?
Nothing but troble from the first day! Slide problem is not new, Fixed that by reading the discussions here (fix is unbelievably funny). Bluetooh connections with HF and carstereo is so annoying that I allmost broke the windshield in my car!!! To fix that problem You probably need two big stones and phone in between ....
I do have heard that new firmware is out some time now!
And my question is WHY THE F...... it`s not available to public?
Or I am so dumb that i cant find it!
Regards,
TV monitors are usually never good for graphic design because they are designed to be viewed from across the room where the pixels merge when being viewed for a distance. So they tend to have bigger pixels and spaced more apart than computer monitors.
Up close requires a higher pixel count per sq inch. So a 17" MacBook Pro has a like 1080i screen up close within a couple of feet as a 50" HD TV has the same at 20 feet.
Since TV content is max at 1080i for 1980 x 1000 pixel count, there is no need to make it bigger for up close and computer use.
Graphic monitors of that larger caliper have something like 3000 x 2000 pixel resolution at 30 and 40" sizes to get the fine detail and less blurry type and images.
If your looking for a larger screen for graphic design, I don't recommend Apple's glossy screens at all, look for a professional anti-glare high res models online.
Apple has been slowly exiting certain markets that depended upon it's hardware in favor of serving only the consumer markets for gizmos.
I fully expect the MacPro to go the way of the XServer in the coming years as demand slacks off for their "Pro" products.
Apple is already introducing only integrated graphics in their "Pro" line of laptops and ineffective for serious professional use glossy displays.

6d wrong choice for portrait work?
Ok guys,
I was debating for quite some time whether to by the 6d or the 70d. Then I debated the 6d vs 5dIII. I went with the 6d based on many reviews, opinins and some great help on this forum. I haven't really had the chance to put it through it's paces yet. I really hate reading manuals, so I bought this short Creative Live class the John Greengo held on the 6d. He was saying that hardly anyone would use this camera in the studio since you have to run it at 1/100 to get a decent sync speed. This makes me nauseous. This was the main reason I bought this camera was for studio portraits. Does anyone have any encouraging words to make me feel like I made the wrong choice? I definitgely want a full frame, so if this isn't the one, I would have to spend twice as much on the 5dIII.I should add... once upon a time nearly every camera that I worked with for studio photography... had a flash sync speed of 1/60th, there was no such thing as "high speed sync", and this really was no problem at all. It's not like we felt we needed to overcome a weakness in the camera to do studio shooting.
As Skirball points out, I do not think you'll have any trouble at all at 1/160th.

I connected my new iPhone 5 to my (now fully updated after two separate operating system upgrades!) MacBook Pro so that I could add my music to my new phone. Rather than configuring it as a new iPhone, I chose to configure it as my old iPhone, thinking that this would make it easier for my music to be there. WRONG. Now my new iPhone 5 looks exactly like my old iPhone 4 did in OCTOBER, 2012 - photos, messages, contacts... anything done since then is gone (that was the last time I had backed up my old phone, which unfortunately was not connected to the cloud and is also lost somewhere in a New England lake :-(). What I could really, really use help with is finding out if I can have a do-over on my choice and at least get my new phone looking/acting like the new phone it is, and bonus would be to have the photos and videos I took with it this past weekend (it's only five days old!) restored. Please help!
Look iTunes>Preferences>Devices...is a backup listed for your iPhone 5 dated BEFORE you restored your iPhone 4 backup to your iPhone 5? If not, your data is gone. If there is a backup, on your iPhone 5: Settings>General>Reset>Erase All Content & Settings. You should now be able to restore that backup, if it exists, to your iPhone 5.

Say... What if MS E64 is not goin to be in retail... Only in OEM... which can be hard to get in some part of the world....
Alrighty... Don't get me wrong, athlon64 processors are nice. Able to do 64-bit stuff, got integrated memory controller... but what if MS E64 is not gonna be there... we'll all just be running 32 bit stuff... Was it worth it to get the athlon64??
I mean with Sempron 3100+ coming, we could have just spend way less to get that...Hi US PRO 666
You playing Devils Advocate here, the 666 and all. :hypecrite:
Well for my 2 bits worth. the FIS2R is the best MOBO about. Stable, lets me stir things up and turn them round, and still comes back for more. The amount of 'flakey ' progs that I load, ' just to see' what will happen, then remove them again. No other board would put up with. Still on my original installs of XP and XP64 bit. Though, it is probably time to do a reinstall. As I am always loking at 'new' stuff, I was thinking Neo2 and 939 pin, for next machine, I have managed to convince myself that we need another 64 bit computer, so have been looking for the next build. However, over the last couple of days, the Neo2 seems to have a prob or two, and is not as fast as I hoped. I'll wait for Sab & RexB to post their experiances, Ears on SAb? As I see it, at this moment, the best available would be the FIS2R and the 3700 AMD64 CPU. The K8N seems to be having some probs, which will take a month or so to sort out. So all in all, unless someone knows differant, my choice would still be the FIS2R and the AMD64s.

Hi... just bought a samsung lcd tv monitor to hook up to my macbook pro, but I can't get good resolution for graphic design. selected highest res possible in s system preferences, but still sucky. Is it not a good choice for a graphics monitor?

Thinkpad T410s - Is the 32-bit a wrong choice for me?
Hi everyone,
I have ordered T410s (2901CTO) with 4GB (2DIMM) and 32-bit Win7. My current concern is about running SAS (Statistical Analysis System) - a statistical and data management software application - that I use to process huge data sets (at least 5GB each). Is the choice of 32-bit a bad choice, because I will not be able to take full advantage of memory upgrades if I want later on.
Say if I buy 8GB for the memory upgrades, then it's only a waster of $$$ as the 32-bit system can only see it but cannot access it. Is that really the case? What is the solution for me now besides returning it and placing a new order for the 64-bit?
Another question is, How can I determine the year/month of release for this model T410s 2901CTO? I've been trying to find it out on the net and I still haven't been able to find any information.
Thanks so much for helping!Hi pantera,
You can order 64-bit version from lenovo without returning your system:- http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-74752
T410s was introduced in the beginning of 2010, if you're looking for the manufacturing date of your system then you can find it on the back sticker, it reads in this format Year/Month (e.g. 09/12).
Hope this helps.

Do you have any explanation why Oracle is using PSIJOB instead of PSAJOB in first case ?
How Oracle could prefer a INDEX FULL SCAN than INDEX RANGE SCAN (PS_JOB is a 3.3 millions rows table) ?
Lastly, here an extract of the trace 10053 file when PSIJOB is used :

FINDINGS SECTION (2 findings)
1- Statistics Finding
Optimizer statistics for table "SYSADM"."PS_AB_PDI_CN_TAO_TMP" and its
indices are stale.
Recommendation
- Consider collecting optimizer statistics for this table.
execute dbms_stats.gather_table_stats(ownname => 'SYSADM', tabname =>
'PS_AB_PDI_CN_TAO_TMP', estimate_percent =>
DBMS_STATS.AUTO_SAMPLE_SIZE, method_opt => 'FOR ALL COLUMNS SIZE
AUTO');
Rationale
The optimizer requires up-to-date statistics for the table in order to
select a good execution plan.
2- SQL Profile Finding (see explain plans section below)
A potentially better execution plan was found for this statement.
Recommendation (estimated benefit<=10%)
- Consider accepting the recommended SQL profile.
execute dbms_sqltune.accept_sql_profile(task_name =>
'sysadm_avoid_psijob', replace => TRUE);

Solid state drive= wrong choice for the newmacbookpro 2010?
Hi
i've been exchanging on the logic pro forum about the ssd vs the hdd serial to configure a macbook pro for logic.
I would love to hear your point of view or experience about that .
also since it's the apple forum i hope there should be some advice from technician from apple.
since from logic pro forum i had the point of view of logic pro certified level 1 and 2
here is the links :
http://www.logicprohelp.com/viewtopic.php?t=57664
http://www.logicprohelp.com/viewtopic.php?t=55058&highlight=solid+state
thanks a lot for any comments or experiences.
junebut why is it bad to record internally today
I didn't say it was "bad" as such, I said I'd only do it when necessary (and I do) but I'd generally still record to external drives where possible.
imagine you're having a 500 GB internally you can still back up on a other drive after.
is there any consequence about that kind of configuration?
The thing is, the internal drive is the system drive, so it has all kinds of drive activity going on in addition to audio - swap file reading and writing, loading apps, utilities, logging functions and many more.
i heard about the lifetime too but more from some experience from 2009 but i don't know what
happen with the new model if they upgrade their ssd in anyway?
Time will tell I guess, these technologies are new and unproven over enough time yet. -
Partition inaccessable due to wrong choice of partition type
Dear friends,
I have created a lot of problem for myself and now I desperately need your help to come out of this mess.
I have an 80GB hard disk with four partitions.
1- C 10GB NTFS
2- D 25GB NTFS
3- E 25GB NTFS
4- not allocated (reserved for Solaris)
(All of these partitions are primary partitions)
I decided to install Solaris 10 for intel on my 4th partition. First I installed it on my friend's laptop
and it is working great. Both Win XP and Solaris are working fine.
Then I tried to install it on my PC. Everything was fine till it reached where it asked for the partition
where I wanted to install the Solaris. On that screen, I choose the partition type for the fourth (unallocated)
partition as Linux/solaris, but by mistake, instead of leaving the partition types of my other partitions C, D
and E as other, I changed the partition types of these trhee partitions as "PRI DOS" thinking that these are the primary partitions.
Solaris was installed fine and it is working, but my other three partitions have become corrupted. I could not boot into Windows XP. From boot manager, when I tried to select partition 1 (C), it displayed some error message like PBR or BPR not found etc.
I tried to check the partitions with fdisk, it showed the partition type of C, D and E as unknown. Then I
installed windows XP again on my C partition and tried to access my D and E partitions, but they are
inaccessable. Although it is showing the partition size, but in properties, it says 0 bytes used and 0 bytes available.
Dear friends, I really can't tell you how much important data is there on these two partitions. I never thought that this mistake would cost me so much. Please please help me getting out of this problem.
I need to know if there's any possibility to correct this mistake with least amount of destruction to the file
systems on these partitions? Is there any data recovery procedure/software which can bring my data back in original form as much as possible??
Any suggestion/solution/clue/pointer in this regard will be very highly appreciated.
Thanks and best regards.
--MACDear Kidari,
Thank you very much for the response and sorry for the late reply from my side. Actually I was posted away from my home for the last two months so could not try the solution mentioned in your mail.
Yesterday I managed to d/l knoppix and tried the method you had suggested. Unfortunately it did not work. It did not recognize the partition.
Here I would like to emphasize on the point that since I changed the partition type to "PRI DOS" during Solaris installation, so it is no more an NTFS partition. Now it has been changed to DOS 16 kind of FS. So all I need is a way to get my data back from a partition which was accidentally converted from NTFS to "PRI DOS". Any procedure/software which can read data from this kind of "changed" partition.
I would appreciate any clue to any other appropriate forum where I would be able to get a bit of help in this regard.
Thanks

I'm afraid I don't know how to repair the NTFS
partitions. You could try to recover their data,
though, using a Knoppix CD. Knoppix is a Linux
distribution which a) runs a full system off the CD
without hitting the hard drive, and b) understands
NTFS.
1. Burn the iso from knoppix.org & boot from it.
2. The devices of your Your NTFS partitions will
probably be /dev/hda1, /dev/hda2 & so on.
# fdisk -l /dev/hda
should tell you.
3.
# mount /dev/hda1 /mnt
4.
# ls /mnt
That should show you all the stuff in the top level
of your first NFS partition. You'll need a network
drive (samba, NFS) to which to copy the things you
really really need. perhaps knoppix will let you
burn CDs too.
Repeat for each partition.
If this doesn't work, and no one else's suggestions
work (try them first!), then you can use the fdisk
utility within knoppix to change the declared
filesystem type
of a given partition: you could try to change the
type back to NFS.
# fdisk /dev/hda
t <to change type>
L <to see hex codes for different FS types>
This fdisking might make your problem worse. though,
so treat this as a last resort. Booting off
knoppix and copying stuff onto the network is safe. -
Lost/Stolen Macbook... Was locking it the wrong choice?
I recently left my Macbook Air behind on a plane, and it appears it was taken by someone (rather than turned in to the airline). I had enabled Find My Macbook, and, a few hours after I lost it/it was taken, someone tried to use it. I received a notification - it was several hours away from my home, so I chose to Lock it instead of erasing it. I don't know why I did - panicked in the moment and thought that if I locked it, they still wouldn't be able to access or use the Macbook.
Now that I'm reading posts, it sounds like I should have erased it because I am no longer able to track it's location while it's locked. And neither Apple or I can remotely unlock it. When I look at Find My Macbook now, the "Lock" button and "Erase" buttons are completely grayed out.
I also never got asked to enter a 6 digit passcode to unlock it, nor was I given the option of putting up a message...
Advice? What can I do/should I do from here? I am hanging on to the glimmer of hope that I can still recover my computer.Please see this article:
If your Mac is lost or stolen - Apple Support
The "Lock Your Mac" section suggests you needed to set up a passcode to perform the lock. Click the "Remotely lock your Mac" link in that area of the article for more info.
Good luck finding it! -
I synced the wrong user profile, how can I switch it?
During installation I was prompted to import a user profile and I accidently chose the wrong one. I uninstalled Firefox thinking I could correct my mistake during the next installation but it automatically used the "wrong" choice I made the first time.
How do I correct this?
thanks!You can use the Profile Manager to select another profile if you have multiple profiles.

Hi guys,
I'm trying to create a multiple choice quiz. I'd like there
to be unique feedback text for each incorrect answer, explaining
why that particular answer is wrong. However, it seems like you can
only make one generic incorrect answer response that will be the
same for every wrong choice. Does anybody know a way around this,
or is there an option that I'm just not seeing?
Thanks in advance for your help.HI ELT
You would like doing comparisons of the questions with the
answer seriate to do a U-turn for the pupil on it because the
answer is missed it would be that.

Did you know the tablets are now available with the Edge program?
While tablets are now able to be purchased with the Edge, the Device Payment Plan has been discontinued. So, if you want to pay over 12 months, to keep unlimited data, you are out of luck. Either full price, or lose it and use Edge.
Just another way for Verizon to get rid of unlimited.I would check again. The problem is when you went to a corporate store and that is the only way to get it. The stores were telling customers that Verizon's device payment plan was only for tablets.
That is the first lie on their parts. The second thing the store would tell customers that if you used the plan you would still lose unlimited data, lie two.
You could not grandfather in a plan such as the device payment plan. Grandfathered to whom? Those who already choose it and are on it? Those who got grandfathered in how? Maybe a wrong choice of word in your post.
Like Ann154 the plan is still showing on the Verizon wireless site.
I also called my former account executive at Verizon and he said he knew of no discontinuance of the program.
So unless you have advance information via working for Verizon wireless I would wait for the news release.
In your case I would go to a corporate store and insist on them honoring the Device Payment Plan. Maybe mention your attorney, or a state regulatory agency etc.
Good Luck -
