Need help! w530 or T540p for photography??
Hello everyone and thank you in advance for your help and expertise! :-)
I am trying to figure out which of these two laptops would serve me better for my photography and Photoshop needs. Having lots of memory, a great screen that will run with Photoshop CS6, IPS and the best color available on the monitor is extremely important to me. Having a vibrant screen is also a must.
It looks like its a trade off between the two. It appears the color gamut and calibration might be better with the w530 but I don't think it has IPS. The T540 doesn't look like it has the color features but has IPS. I just cant decide and really want to get this right because its a huge purchase for me.
If you can help me I would appreciate it so much.
Please let me know
greyhoundrick,
I'm a photographer and I produce multimedias. I hope I can help.
"Having lots of memory, a great screen that will run with Photoshop CS6, IPS and the best color available on the monitor is extremely important to me. Having a vibrant screen is also a must."
I need to narrow these in points to make it simple and hope to help in your choice of laptop:
On Panels...
* Normally, IPS and full coverage of AdobeRGB don't go hand in hand unless you have a true high end panel. These panels would usually be made by NEC (in their PA and Spectraview lines) or Eizo.
* The W530 panel does indeed cover AdobeRGB (I have one and can attest to it since I also own an NEC PA241w) but the viewing angles are not the greatest (albeit much better than the vast majority of TN panels)
* I don't know the quality of Lenovo's IPS panels but the X230 did not really cover much of the sRGB space although it doesgive you the nice viewing angles. However good will the T540/W540 panels be, I don't know and I can't advise.

* Apple's MBP Retina however does indeed cover almost all of sRGB but goes about halfway on AdobeRGB. A really good performance, indeed.
http://www.notebookcheck.net/Review-Apple-MacBook-Pro-15-Retina-2-3-GHz-Mid-2012.78959.0.html
* In Conclusion, what is more important to you? A wide-gamut display or an IPS screen? I work with Ps, Lr and DxO and I can tell you that the colours are very different when you work in either scenario. More so if your cameras are shooting in the AdobeRGB space (which Sony, Canon and Nikon can do)
Is the viewing angle imporant? is it more important that the colour gamut? Only you can answer that. I am completely happy with the W530's screen and I can work seamlessly with it along with my NEC monitor (both can be calibrated almost identically with Spectraview II for the NEC and DispcalGUI for the W530's screen)
You also mention "vibrant", but that is as subjective as you can get in the visual field. We could discuss contrast ratios, colour gamut coverage, brightness, gamma... all of these can affect "vibrancy" depending on who you talk to.
On Memory...
* You can do that with either system so money is the only issue, if an issue.
Photoshop is RAM intensive in as much as you open many files at the same time (not just open them in ACR before opening them in Ps) and it can, indeed, use as much RAM as you give it. The second most needed part of Ps is CPU power for filters and batch operations (like the ones you can use with Bridge)
Lightroom (if you ever consider it) is a resource idiot. Even if you had 32GB of RAM, it would still stick to 4...or 5...and will always lag behind. Why does Adobe not make it more powerful, no one knows.
On Video Cards...
This is more complex and I have yet to find a proper answer. I chose W530 because I also work on video and it handles Premiere Pro very well. The nicest thing about Quadro is the ability to give me 10bit all the way to the NEC monitor, which helps greatly with the gradients thanks to its ability to show a billion colours instead of just 16 million. That, and also the ability of handling Premiere Pro so well. I don't know if the T540 video card will be able to do this.
It sounds like you are starting in photography. If you have the means to get any of these two systems, I would suggest saving some cash and buying a proper IPS monitor like an NEC PA or an Eizo. Whatever you do, do not buy the HP or Dell monitors since they will not be able to do hardware calibration and their price isn't as competitive for the class as one might think. Same goes for the apple monitors. Not worth the money in the long run.
Hope this helps.

Need help in developing BADI for IT0001
Hi All,
I need help in developing BADI for IT0001.
On IT0001 create or change, there is need to update IT0017 with following data from IT0001
-Company Code
-Cost center
-Business Area
-Begin and End Date.
Other fields from IT0017 need to be derived from Position and update in IT0017.
Please guide me how I can address this. I do not want to go for dynamic action, as it is not getting evoked during background jobs.
I am new to BADI development and will appreciate step by step instructions.
ThanksHi,
follow the below steps to achive
Steps:
1. Execute Business Add-In(BADI) transaction SE18
2. Enter BADI name i.e. HRPAD00INFTY and press the display
button
3. Select menu option Implementation->Create
4. Give implementation a name such as Z_HRPAD00INFTY
5. You can now make any changes you require to the BADI within this
implementation, for example choose the Interface tab there are 3 methods avialble
6. Double click on the method you want to change, you can now enter
any code you require.
7. Please note to find out what import and export parameters a
method has got return the original BADI definition
(i.e. HRPAD00INFTY) and double click on the method name
for example within HRPAD00INFTY contract is a method
8. When changes have been made activate the implementation

Need help with calculator project for an assignment...
Hi all, I please need help with my calculator project that I have to do for an assignment.
Here is the project's specifications that I need to do"
"""Create a console calculator applicaion that:
* Takes one command line argument: your name and surname. When the
program starts, display the date and time with a welcome message for the
user.
* Display all the available options to the user. Your calculator must include
the arithmetic operations as well as at least five scientific operations of the
Math class.
-Your program must also have the ability to round a number and
truncate it.
-When you multiply by 2, you should not use the '*' operator to perform the
operation.
-Your program must also be able to reverse the sign of a number.
* Include sufficient error checking in your program to ensure that the user
only enters valid input. Make use of the String; Character, and other
wrapper classes to help you.
* Your program must be able to do conversions between decimal, octal and
hex numbers.
* Make use of a menu. You should give the user the option to end the
program when entering a certain option.
* When the program exits, display a message for the user, stating the
current time, and calculate and display how long the user used your
program.
* Make use of helper classes where possible.
* Use the SDK to run your program."""
When the program starts, it asks the user for his/her name and surname. I got the program to ask the user again and again for his/her name and surname
when he/she doesn't insert anything or just press 'enter', but if the user enters a number for the name and surname part, the program continues.
Now my question is this: How can I restrict the user to only enter 'letters' (and spaces of course) but allow NO numbers for his/her surname??

What you could do is checking the input string for numbers. If it contains numbers, just reprompt for the Name.

Need help choosing optimal hardware for a laptop that will run AE CS5
BACKGROUND INFO (Questions listed below)
I need some help figuring out the best hardware configuration for a new laptop. I’m a student at a design school and I will be using the laptop to mainly run After Effects and to a lesser extent Photoshop and Illustrator. I don’t need to worry about 3D rendering software or Premier Pro. I am primarily interested in getting the best performance during editing. I am not looking for the best performance for final output. I would prefer to sacrifice final output times for better editing/interface performance.
I will be working with standard definition content and perhaps HD up to 720p on occasion. I do not need to operate in resolutions higher than 720p. My projects are generally animation and use many sources and many layers.
I’ve been reading up on optimal hardware configurations for CS5 but my understanding is still a little foggy and I would like to use this thread to figure out how to build the best machine for my budget. The budget is about $1400 to $1600 CANADIAN after tax.
I DON’T need help finding the laptop. I will search for it on my own. I just need to understand the best hardware to purchase within my budget.
I realize that it is probably impossible to buy the laptop I want with the hardware configuration I need “off the shelf”. Instead I will be looking for a good base model (~$900-$1100) and I will purchase the necessary hardware upgrades separately. I will not be purchasing a Mac.
Right now I’m thinking of a machine built something like this:
- 15”-16” screen (17” models are too big/heavy)
- Mid to high end i5 processor OR entry level i7 quad core
- 8GB RAM (I would go to 12GB, but it’s hard to find a 15”-16” laptop with 3 memory slots)
- SSD to replace HDD (However, if possible, I would like a laptop with dual HDD support or swap the optical drive for another HDD. If I had access to 2 drives, I would have and HDD/SSD combo).
- Medium/high end NVIDIA GPU to take advantage of OpenGL while editing.
QUESTIONS
1) Does the “Render Multiple Frames Simultaneously” option enhance general editing performance (applying filters, scrubbing through the timeline, reverting history states)? Or does it ONLY help speed up RAM previews and final output? Does it reduce the length of RAM previews?
1b) Is this option even necessary to enable on 64bit systems? (As far as I understand it was used to solve a problem where 32bit systems/software would only recognize 4GB of RAM per instance of AE).
1c) If I turn this option on to help with RAM previews, would I be hindering general editing performance in any way? Or does this option have basically zero drawbacks?
2) How come “Actual CPUs that will be used” will read 0 even if the sum total of RAM assigned to the CPUs plus the RAM reserved for other applications is less than the total available system RAM (on a 64bit system)? For example, I currently have 4GB RAM and 2 installed CPUs. I have 1.5GB reserved for other programs and when I set 0.75GB per CPU both CPUs are used. However when I set 1GB per CPU then 0 CPUs are used, even though the total RAM adds up to only 3.5GB.
CPU
3.) Considering the fact that I am more concerned with smooth performance while editing rather than final output speeds, would it be better to get a dual core i5 clocked around 2.5 or a quad core i7 clocked around 1.8?
4.) What is the difference between an i3 and an i5 processor even if they are clocked at the same speed? How does an i5 460M compare on the grand scheme of things?
RAM
6.) Should the quantity of RAM that I get (8GB vs 12GB) be based on the number of cores in my CPU? If so, how should I be calculating optimal RAM based on # of cores. Should I also be counting threads, or just actual physical cores?
STORAGE/SWAP
7.) Should I replace the HDD with an SSD? I'm looking for snappy interface performance while editing. I would think that if the RAM fills up it would be best to have the SSD for scratch/cache.
8.) What performance benchmarks are most important when considering an SSD for After Effects? (4k writes? IOs per second? Max read/write?)
9.) I can afford the OCZ Vertex2 120GB SSD. Would this be a good choice if an SSD is recommended?
10.) Would it be better to have 8GB of RAM and an SSD, or 12GB of RAM and an HDD? Explain why.
GPU
10.) After Effects utilizes OpenGL to enhance editing performance. I will not really be using Premier Pro, so catering to the CUDA Mercury Engine is not a concern. Do high end gaming cards provide significant gains in OpenGL performance? Or do OpenGL performance gains taper off around the mid-range GPUs? (i.e. can you justify buying a high end GTX 260M graphics card for enhanced editing performance versus an "entry level" dedicated card like the 310M?)
11.) What hardware specs are most important when considering a GPU for editing performance in AE? (Memory size? # of Pixel shaders? Core speed? Shader speed?)
Thanks so much for any answers you can offer to these questions.Please make sure that you've read through this page and what it points to.
> 1) Does the “Render Multiple Frames Simultaneously” option
enhance general editing performance (applying filters, scrubbing through
the timeline, reverting history states)? Or does it ONLY help speed up
RAM previews and final output? Does it reduce the length of RAM
previews?
It only increases rendering speed for RAM previews and rendering for final output. In After Effects CS5, it doesn't decrease the length of RAM previews. (In CS4, it does.)
1b) Is this option even necessary to enable on 64bit
systems? (As far as I understand it was used to solve a problem where
32bit systems/software would only recognize 4GB of RAM per instance of
AE).
You misunderstood. Yes, it's still relevant on 64-bit computers. Moreso, in a way. (I'd rather not spend my entire Sunday writing out detailed answers to satisfy idle curiosity, so I'm not going to give all the technical detail to that answer.)
> 1c) If I turn this option on to help with RAM previews,
would I be hindering general editing performance in any way? Or does
this option have basically zero drawbacks?
It takes a small but nonzero time for the background processes to start up when they need to be used and shut down when they're done. And as they sit waiting, they take up a little bit of memory. So, it's not exactly correct to say that there are no downsides to leaving it on. But it's close. I leave it on.
> 2) How come “Actual CPUs that will be used” will read 0 even
if the sum total of RAM assigned to the CPUs plus the RAM reserved for
other applications is less than the total available system RAM (on a
64bit system)? For example, I currently have 4GB RAM and 2 installed
CPUs. I have 1.5GB reserved for other programs and when I set 0.75GB per
CPU both CPUs are used. However when I set 1GB per CPU then 0 CPUs are
used, even though the total RAM adds up to only 3.5GB.
4GB - 1.5GB for other software leaves 2.5 GB for After Effects.
If you have 1GB assigned per background CPU, then the foreground takes 1.2x that = 1.2GB. That leaves 1.3GB for background processes, which is enough for one background process. There's no point in starting only one background process to do rendering, so it doesn't bother. (Note: When background processes are rendering, the foreground process isn't rendering.)
> 3.) Considering the fact that I am more concerned with
smooth performance while editing rather than final output speeds, would
it be better to get a dual core i5 clocked around 2.5 or a quad core i7
clocked around 1.8?
Get the quad-core. That gives you a greater total number of cycles. And After Effects works very well with mutliple processors, even beyond Render Multiple Frames Simultaneously multiprocessing. An entirely unrelated sort of multiprocessing (multithreading) spreads work out to multiple processors.
> 6.) Should the quantity of RAM that I get (8GB vs 12GB) be based on the number of cores in my CPU? If
so, how should I be calculating optimal RAM based on # of cores. Should
I also be counting threads, or just actual physical cores?
The optimum amount is the amount that you can cram into the computer. I'm not kidding. Spend your budget on RAM until you have 4GB installed per processor (and I'm counting the virtual processors due to hyperthreading). If you have a quad-core, that's 8 CPUs with hyperthreading, so the optimum amount of RAM installed is 32GB. You can work with less, but you did ask about optimum. For HD work (i.e., 1920 pixels across), you're OK with more like 3GB installed per CPU. That's what I have at home: 24GB in a quad-core. You're going to assign 2/3 or so of the RAM to After Effects, so 3GB installed per CPU is 2GB per core for HD work in After Effects.
> 10.) Would it be better to have 8GB of RAM and an SSD, or 12GB of RAM and an HDD? Explain why.
12GB of RAM. Because After Effects likes RAM. (If you're thinking of deliberatly using virtual memory to swap memory to the hard disk, don't. That's a performance killer.)
> 10.) After Effects utilizes OpenGL to enhance editing performance.
Not really. If you're on a limited budget, don't even think about the GPU until you've already got the most RAM, the fastest CPUs, the largest number of CPUs, two fast hard disks, and a couple of good monitors. Then, and only then, should you even consider getting soemthing beyond a non-stock graphics card. Yes, OpenGL can be used to accelerate some things, but that's only for the low-fidelity preview renderer. (Pardon the bluntness, but I want to make sure that you heed this.) -
Need help in dynamic report for a range of year and period
Dear all,
I need help in creating an ALV report with dynamic columns based on the Year and period entered on the selection screen. for example if in the year we enter 2002 and period range from 10 to 12 then we should get the 3 columns display for cost(example) for period 10/2002, 11/2002 and 12/2002.
Can anyone help me in achieving this dynamically since the user can enter the year also in intervals along with the period and data also needs to be populated in the corresponding columns.
An example code would be of great help.
Thanks,

Need help in shutdown primary for maintaince (new to oracle dba)
Hi,
BANNER
Oracle9i Enterprise Edition Release 9.2.0.4.0 - Production
PL/SQL Release 9.2.0.4.0 - Production
CORE 9.2.0.3.0 Production
TNS for Linux: Version 9.2.0.4.0 - Production
NLSRTL Version 9.2.0.4.0 - Production
actually we have primary database server and the physical standby server with protection mode is maxperformance and for maintaince we need to shutdown primary server so what are the steps i need to follow since my primary database is configured with DATAGAURD and i would like to follow the folllowing steps please advice me:
to shutdown standby server:
from primary server connecting to dgmgrl
dgmgrl>DISABLE SITE standby_site1;
then connecting to standby server
sql>alter database recover managed standby database cancel;
sql>shu immediate;
and finnaly connecting to primary server
sql>shu immediate
is it right since i am new to datagaurd concept need help.
Regards
PrakashYou can do so, but you would shutdown the whole standby environment. But normally standby is used to have no or only short downtime. So a switchover to the standby DB is performed (after this standby is now running as primary), maintenance is done on the primary and then at the end another switchover back from the 'new' primary to the 'old' primary.

Need help on SQL Statement for UDF
Hi,
as I am not so familiar with SQL statements on currently selected values, I urgently need help.
The scenario looks as follows:
I have defined two UDFs named Subgroup1 and Subgroup2 which represent the subgroups dependent on my article groups. So for example: When the user selects article group "pianos", he only sees the specific subgroups like "new pianos" and "used pianos" in field "Subgroup1". After he has selected one of these specific values, he sees only the specific sub-subgroups in field "Subgroup2", like "used grand pianos".
I have defined UDTs for both UDFs. The UDT for field "Subgroup1" has a UDF called "ArticleGroup" which represents the relation to the article group codes. The UDT for field "Subgroup2" has a UDF called "Subgroup1" which represents the relation to the subgroups one level higher.
The SQL statement for the formatted search in field "Subgroup1" looks as follows:
SELECT T0.[Name] FROM [dbo].[@B_SUBGROUP1] T0 WHERE T0.[U_ArticleGroup] = (SELECT $[OITM.ItmsGrpCod])
It works fine.
However, I cannot find the right statement for the formatted search in field "Subgroup2".
Unfortunately this does NOT WORK:
SELECT T0.[Name] FROM [dbo].[@B_SUBGROUP2] T0 WHERE T0.[U_Subgroup1] = (SELECT $[OITM.U_Subgroup1])
I tried a lot of others that didn't work either.
Then I tried the following one:
SELECT T0.[Name] FROM [dbo].[@B_SUBGROUP2] T0 WHERE T0.[U_Subgroup1] = (SELECT T1.[Code] FROM [dbo].[@B_SUBGROUP1] T1 WHERE T1.[U_ArticleGroup] = (SELECT $[OITM.ItmsGrpCod]))
Unfortunately that only works as long as there is only one specific subgroup1 for the selected article group.
I would be sooooo happy if there is anyone who can tell me the correct statement for my second UDF!
Thanks so much in advance!!!!
Edited by: Corinna Hochheim on Jan 18, 2010 10:16 PM
Please ignore the "http://" in the above statements - it is certainly not part of my SQL.
Please also ignore the strikes.Hello Dear,
Use the below queries to get the values:
Item Sub Group on the basis of Item Group
SELECT T0.[Name] FROM [dbo].[@SUBGROUP] T0 WHERE T0.[U_GroupCod] =$[OITM.ItmsGrpCod]
Item Sub Group 1 on the basis of item sub group
SELECT T0.[Name] FROM [dbo].[@SUBGROUP1] T0 WHERE T0.[U_SubGrpCod]=(SELECT T0.[Code] FROM [dbo].[@SUBGROUP] T0 WHERE T0.[Name] =$[OITM.U_ItmsSubgrp])
Sub group 2 on the basis of sub group 1
SELECT T0.[Name] FROM [dbo].[@SUBGROUP2] T0 WHERE T0.[U_SubGrpCod1]=(SELECT T0.[Code] FROM [dbo].[@SUBGROUP1] T0 WHERE T0.[Name] =$[OITM.U_ItmsSubgrp1])
this will help you.

GROUP BY application_type
ORDER BY application_typeThat's the bais idea.
You can simplify it a little by factoring out the date differences:WITH got_d AS
SELECT qty
, TRUNC ( dt
- ADD_MONTHS ( TRUNC (SYSDATE, 'MON')
, -1
) AS d
FROM table1
WHERE dt >= ADD_MONTHS ( TRUNC (SYSDATE, 'MON')
, -1
AND dt < TRUNC (SYSDATE) + 1
SELECT SUM (CASE WHEN d = 1 THEN qty END) AS day_1
, SUM (CASE WHEN d = 2 THEN qty END) AS day_2
, SUM (CASE WHEN d = 62 THEN qty END) AS day_62
FROM got_d

Need help writing a query for following scenario
Hi all, I need some help writing a query for the following case:
One Table : My_Table
Row Count: App 5000
Columns of Interest: AA and BB
Scenario: AA contains some names of which BB contains the corresponding ID. Some
names are appearing more than once with different IDs. For example,
AA BB
Dummy 10
Me 20
Me 30
Me 40
You 70
Me 50
Output needed: I need to write a query that will display only all the repeating names with their corresponding IDs excluding all other records.
I would appreciate any input. ThanksIs it possible to have a records with the same values for AA and BB? Are you interested in these rows or do you only care about rows with the same value of AA and different BB?
With a slight modification of a previous posting you can only select those rows that have distinct values of BB for the same value of AA
WITH t AS (
SELECT 'me' aa, 10 bb FROM dual
UNION ALL
SELECT 'me' aa, 20 bb FROM dual
UNION ALL
SELECT 'you' aa, 30 bb FROM dual
UNION ALL
SELECT 'you' aa, 30 bb FROM dual
SELECT DISTINCT aa, bb
FROM (SELECT aa, bb, COUNT(DISTINCT bb) OVER(PARTITION BY aa) cnt FROM t)
WHERE cnt > 1;
