Best approach to use 2 one dimensional position stages for laser engraving

Hi,
I currently have two 1dimensional position stages (NRT150 from Thorlabs) that I want to use to hold a sample object as a fixed high power laser engraves the moving object. How should I go about programming these stages so that they can move together to engrave either an image or some lettering onto the object?
Thanks for any feedback!

But you've told us nothing about how they are to operate.
Somebody else has speculated they are GPIB or RS232.
Is is GPIB? Is it RS232? Is it TCP? Does it have analog inputs?
Does it have a command set?
I don't understand what you need to know.

Best Approach: All IDocs in one software component or not

Hi All
We are in the process of importing IDocs into PI system. We are maintaining software components based on legacy system.
We have two oprions to imports idocs into software components
1. Import all idocs into common software component (In this case i am thinking with respect to transports)
2. Import to respective legacy software component
Could you please suggest best approach?
Thanks
Sai

Thanks prateek.
Actually we have some idocs common across sofwtware components. Thats why we are planning go for common software component which can maintain all ECC objects.
If we maintain like this, is there any problem in test and production mainly during transports- dependency from one SWC to common SWC.
Thanks

How do you use only one plugin in Logic for multiple guitar tracks? I want to only use one instance of Pod Farm and run all my guitar tracks through that one instance.

I want to be able to use only one instance of Pod Farm for my guitars, and have all of my guitar tracks run through it while I'm recording.

What he said. Or here is a similar approach with a picture.
1. Press the SEND button on every stereo (or mono) guitar track you want to send through the effect. Then select a free bus.
2. Make sure you turn up the amount of send (in db). Holding alt while leftclicking on this circle sets the send level to 0 db wich is good.
3. Open the mixer (Cmd+2). Please see that I here have turned the output off from the stereo guitar track. That way the only output will be the BUS, in your case the AmpTrack bus where all your guitars will pass through. If you want both the original guitar sound AND the Ampfarm effect then just set all outputs on your guitar tracks to Stereo Out, like the AmpF Bus track is set in my picture.
4. Insert your AmpFarm plugin here. I don´t have that plug so I inserted Waves Renes Axe for demo purpose.
Adjust the volume/effect of every guitartrack by turning the circle input shown as 2. in my picture.
I now see that you mentioned Pod Farm, not AmpFarm. But I guess it´s the same trick.
Have fun.

Best approach to use with OTT

Hi
We have a application (c code) that currently uses a ISAM file based DB.
We want to replace this with Oracle9i.
My thoughts would be to create Oracle OBJECTS data types and use the OTT utility to automaticaly create the associated c structs.
We could then create wrappers around the existing c modules that interface to the ISAM tables & point them to Oracle using the new c structs.
What I need to get a better picture on is the pros & cons of using:
- PROC*C
- OCI
What benefits are there in using embedded PL/SQL with either technology?
Are there any other tools that I could use to map the Oracle9i entities to the relevant c structs?
Any thoughts or tips based on your experience would be greatly appreciated.
Cheers Luie

Luie,
You may also consider using OCCI, which is the C++ API to the database. Since you are working with objects, OCCI may fit you best, since C++ is object-oriented. OTT works with OCCI as well. Please see:
http://otn.oracle.com/tech/oci/occi/index.html
for more information. Hope that helps!

Best approach to using command link from within a custom component

I have created a navigation component "Menu" , used as follows:
<custom:menu />The contents of menu are stored in an xml file and the Menu component delegates the rendering to a custom renderer, which basicaly writes out html links. (Actually, the component does a lot more, but I'm simplifying to get to the point.).
Sometimes, I need to render a command link instead of a regular html link. I don't want to re-invent the wheel here, so I want to delegate this to the standard command link components.
Approach 1: create child components within the Menu component constructor, e.g.
HtmlCommandLink c = new HtmlCommandLink();
          MethodExpression e = FacesContext.getCurrentInstance().getApplication().getExpressionFactory().
               createMethodExpression(FacesContext.getCurrentInstance().getELContext(),
               "#{registrationEditor.enterSubmission}",
               String.class,
               new Class[] { });
          c.setActionExpression(e);
          c.setValue("TestLink");
          c.setTransient(true);
          getChildren().add(c);Approach 2: delegate to the CommandLinkRenderer within my custom renderer, e.g.CommandLinkRenderer delegate = new CommandLinkRenderer();
                    HtmlCommandLink link = new HtmlCommandLink();
                    ExpressionFactory elFactory =
                         FacesContext.getCurrentInstance().getApplication().getExpressionFactory();
                    MethodExpression actionExpression =
                         elFactory.createMethodExpression(context.getELContext(), c.getExpression(), String.class, new Class[] {});
                    link.setActionExpression(actionExpression);
                    link.setParent(component.getParent());
                    link.setValue(c.getLabel());
                    delegate.encodeBegin(context, link);
                    delegate.encodeChildren(context, link);
                    delegate.encodeEnd(context, link);Is either of these a respectable approach - they feel a little hackish. If so, which do you prefer. If not, what do you recommend?
Thanks
Richard

I think either is a fine approach and not at all hackish. I prefer the second, although I couldn't tell you why (just a gut feeling). That said, I haven't tried either so there may be hidden problems. My main concern would be what happens when the request is submitted from the page, that the Restore View phase is done correctly so that the proper event is fired.

Best settings to use when preparing HD source material for iDVD?

I realize iDVD is effectively abandonware, and that it was never really designed either to run on Lion nor to import high definition content...but nevertheless here I am (somewhat unavoidably) trying to do both and constantly getting the dreaded and mysterious "an error occured during movie encoding" result when I try to burn or export my project to a disc image.
If it matters, I am using a Mac Pro (1,1) with a 5770, running 10.7.5 with 8GB of RAM and oodles of free diskspace. All of my software is fully up to date, including iDVD 7.1.2 build 1158. Several utilities report nothing erroneous with my drives or their filesystems. I have made sure Perian is not installed. I have tried to create and export this DVD using both my primary user account and a clean dummy one I made for testing purposes.
After considerable trial and error experiments, each taking several hours to attempt, I've decided that I'm never going to easily figure out exacty which of my many various source files for this project (holiday videos for family) may be giving iDVD hiccups. Instead, I've decided to take another approach, making all of my content as easy to "spoon feed" to iDVD as possible. Hopefully then I can get this project done.
My question is what, ideally, does iDVD like to be fed?
For starters, I am in the process of transcoding and repackaging all of my content through MPEG Streamclip to be AIC video and uncompressed audio inside MOV containers. In each case I am scaling the video down to be 480 lines tall. Just guessing, but that seems like it would give iDVD the least possible work to "think" about and get confused. Does that sound about right to folks?
Should I be doing something drastic and old school like trying to create DV files? My content is all wide aspect, intended for a 16:9 iDVD project and that seems like it would get tricky (also, this would involve more quality loss than using AIC files).
I am totally open to suggestions here. Just please don't say "dude, use Toast" or something because while I have plenty of other tools that I know would work more easily and reliably, I really want to mimic the holiday discs from previous years that I've created using the same iDVD theme.

I haven't had to wrestle with this problem, but I've followed some of the discussions and here are several ideas and resources which seem reasonable. As background, have you read about better results from using iMovie6? Also, as you imply, DV Stream (.dv) was the native format for iDVD.

Her own ID. You cannot transfer purchases between IDs so anything bought on your account will require your authorization should she need to download in the future.

Best approach for transition to IFRS from US GAAP

Hi SAP Gurus,
I have gone through some of SAP presentations and also 2 EcoHub sessions on IFRS.
I understand the SAP's suggestion to use of Parallel ledger as best approach.
Can any one clear below my queries?
1. Assuming current SAP system is in ECC 6.0 with classical ledger and we are trying to migrate to SAP GL. It is suggested to migrate to SAP GL first (lets say by 2010) and plan for adopting IFRS as one of parallel ledger (Non Leading) as a separate project (lets say from 2012). For the years 2012 & 2013 we will have reporting both in US GAAP & IFRS. Till here it is clear. I am not sure how we can drop reporting in US GAAP from 2014 when it is set as leader ledger while migrating to SAP GL.
Is there a way to migrate the IFRS non leading ledger as Leading ledger by 2014 and deactivate 0L - US GAAP ledger from 2014?
2. Although I understand the reporting in IFRS can happen prospectively from 2012 onwards, I am not sure how to build the open balances as of 2012. For E.g., how to get the current book values of Fixed Assets as per IFRS principles.
3. Is it advisable to migrate to SAP GL with leading ledger as IFRS directly and marking one of non leading ledger for US GAAP reporting? And how to drop posting in US GAAP non leading ledger from 2014 onwards?
Thanks in advance,
Regards,
Som

Best Approach to Compare Current Data to New Data in a Record.

Which is the best approach in comparing current data to new data for every single record before making updates?
What I have is a table with 5,000 records that need to be updated every week with data from a data feed, but I dont want to update every single record week after week. I want to update only records with different data.
I can think of these options:
1) two cursors (one for current data and one for new)
2) one cursor for new data and one varray for current data
3) one cursor for new data and a select into for current data.
Thanks for your help.

I don't recommend it over merge, but in theory you could use a checksum (OWA_OPT_LOCK.checksum()) on the rows and if they differ then copy the new row into the destination table. Or you might be able to use rowscn to see if things have changed.
Like I said, I don't know that I 'd take either approach over merge, but they are options.
Gaff
Edited by: Gaff on Feb 11, 2009 3:25 PM
Actually, rowscn between 2 tables may not be an option. I know you can turn a rowscn into a time value so if that rowscn is derived from anything but the column values for the row that would foil that approach.

Best way to use an external drive

Hello all,
I have several photos.
I also have three computers that I regularly use: my Windows PC, my Macbook Pro, and a very new iMac.
Rather than place all my photos on each computer... I thought I could place them on a Western Digital Passport portable ext. drive. Then somehow use the drive from computer to computer to edit/play with my photos.
How do I best use iPhoto 08 to do that? I'm not sure... do the photos have to be on the computer in order to make albums, libraries, folders, etc? Or are those things more of thumbnails that POINT to certain files?
Please help a newbie understand the best way to use his external drive.
Thanks for any and all help!

Hello, and welcome, Theodore!
I must first say that I don't yet have iPhoto 8.
I do, however, have a lot of experience with external drives (I have two). I have a huge amount of music in iTunes, so I keep a copy of it on each external drive. Then, when I need to access my music , I turn on either external drive, up comes the External Drive symbol on my display, then I go over to my dock, and select iTunes. I must remember to first open up the External Drive BEFORE I open iTunes (or iPhoto). I then add or subtract music (or photos), edit, and work on my collection. When I'm finished, I just close the application, then select the Hard Drive symbol, and choose File/ Exit Hard Drive. Reach over and turn off my Hard Drive, and it's all good. I just always remember to open the Hard Drive FIRST, before opening the application.
The same would work for iPhoto. If you place iPhoto onto your external drive, you could probably use any of your computers to connect to it. I would suggest you think about backing up your external drive's contents with either another external drive (which was my choice), or other alternate storage methods.
I only have one PowerBook, not multiple computers, but, other than that, the situation's the same. You want to keep your iPhoto collection off your computers, and onto one external drive. I hope this information can be of some help to you.
All best wishes... Cea

Woes of the Z10, and now i want to use it as a backup phone for my contacts and data. Can I?

Ok, this has been a real nightmare. I am an extensive user of BB since OS4. Wanted to try the new Z10, so I got myself a spanking new one. With my prior experience in switching devices, it would be a cinch. Transfer device over via blackberry desktop software, change the emails via BIS, and I'm all sorted out.
OMG dear blackberry. You made me jump through so many hoops I felt like a circus dog.
Blacberry desktop doesn't work with the Z10. No one told me. I had to find out the hard way after not being able to detect the phone. wasted half an hour of my life. Downloaded Blackberry link. Transferred my contacts and everything over, couldn't be happier.
Hurrah, thought the nightmare was done. It was just starting.
Micro sim. Not everyone has a microsim cutter lying around. Great. Troop off to the shop. Figured after I get the sim cut, I could also transfer the emails via BIS server. So that's what I did. (oh by the way, having to buy a micro SD card was also a pain in the A but still acceptable). The BIS server detected the change in device so it disabled my emails. No problem. Until the technician told me at the store-sorry-BIS DOESNT WORK WITH Z10. Whaaaaat? Come on blackberry! Now its just normal emails, similar to that of iphone and samsung. Emails were your best feature. Ok, this I can stomach. What I cannot stomach is...blackberrry, you just killed your frequent traveller who needs international roaming. BIS emails and BBM was wonderful. I could get by travelling from country to country on 50mb a month unlimited. Apparently not anymore. I need a full fledged international roaming plan that will cost me an arm and a leg. This is insane.
Finally I had the Z10 working. I manually entered all my emails. ( i have 9 emails. Thank god they are all gmail based, especially for work, if not I would have ripped all my hair out). For the whole 2 hours, I looked at it and hated it. It was hard to use, I had to keep swiping up and to the right, sometimes it wouldn't swipe well, sometimes I couldn't tell if it was swiping or not. Neither did it help that Whatsapp hasn't even been sorted out on the Z10. Whatsapp is my life. My family's on it. My friends are on it. My suppliers and my customers are on it. Oh wait. Z10-well, you can download it from the appworld, but it doesn't install. Thinking it was a problem with the downloads, I kept at it..only to have the technician tell me, "sorry, Whatsapp not working on Z10, too bad"...anyway I made up my mind to go back to the Torch. So thinking it would be as simple as changing the hub ID on the Z10 and then reactivating the Torch. All will be well. Wrong.
I had to run to another tel shop to beg for a spare sim shell so I could stick the micro sim into it and have it back as a normal sim. Another 2 hours of my life later, I realise-changing the hub ID on the Z10 doesn't change anything. It doesn't mean you can just use the original hub Id and all systems are go on the first phone. Changing the hub ID means changing the original one. Argh. This was so frustrating especially when the BIS server refused to switch back to the old device. Ever clicked on detect device 200 times? Well that would be me. Eventually I figured it out. Change back to the old hub ID, security wipe the horrible thing, log in with the original hub ID and reset the device via BIS server. Finally, order is restored.
Which leads me to my question. I am thinking of porting over my contact list and data to the Z10, and using it as another phone in another country. However I want to use a different Id from my Torch since it is considered a different device but with the same data. Will blackberry link allow me to do this, or will it only switch the data provided the hub ID is the same?
Blackberry, hand over heart, I'll use the Torch till it dies ( I just changed out the nav pad cause it was completely worn out and would act wonky in sunlight- I call it the blackberry vampire version) and after that I'm off to another smart phone platform. You've made my life miserable. It was great while it lasted, but I'm going to be migrating to another platform eventually. Thanks for the memories.

Hello,
BlackBerry 10 has always been advertised as a revolutionary change from prior...not an evolution. And you have both now learned the hard way just how detailed that change is. As with so many things, the assumptions made from past experience with BB are not useful for this very significant change. Rather, research done prior to purchase is the most useful activity one can undertake.
For BB10, BIS is not required. Indeed, on some carriers, having BIS on the account actually impedes some services for BB10. BB10 uses a full on-device ActiveSync client for email now. BIS-handled email is gone...as are "hosted" email accounts (though you can get 1-year of forwarding).
Migrating of data from old to new involves many choices before beginning. For example, if you are not afraid of placing your Calendar and Contact data "into the cloud", the Z10 can excellently synchronize that against many different providers (many more than BIS ever could). Done correctly, one can attain full end-to-end OTA synchronization of Calendar/Contact data between Outlook desktop client (and perhaps others, though I've not tested), a Z10, a PlayBook, and more (for me, I've got 2 Outlook client instances, one Z10, one PB, and one Droid...all working beautifully OTA).
Traveling is no more challenging than in the past...your specific device must be able to function on the networks upon which you wish to roam...this is no different from before (e.g., a GSM-only device simply cannot roam on a CDMA network). To compare specifics, I've found this useful:
http://www.bbin.in/en/2013/03/03/4-types-blackberry-z10-models-fits-better/?utm_campaign=4-types-of-...
There are many other differences...but please try to let go of what was before, for pretty much none of it applies anymore. BB10 is revolutionarily different from before.
Good luck!

Best approach to creating a TOC for product catalog using data merge

What is the best approach for creating a TOC for a product catalog (over 1,000 items) using Data Merge?
The TOC would contain the product Categories.
So for example, Category A items could go from pages 1 - 3, and Category B items would start at pg 4, but if new items were added to Category A, then Category B may start from pg 6.
From the Data Source, there are 5 Data Fields I've chosen to be displayed. If this were a regular digital print document, I could use the Paragraph Style method for creating a TOC, but if I make any one of the Data Fields a certain Paragraph Style and use that for the TOC, it'll populate the TOC with that Data Field for all the items.
Any suggestions?

Peter Spier wrote:
TOC is not interactive in the ID file, though it can be in a PDF that you export (there's a checkbox to create PDF bookmarks). You might want to think about using Cross-references (rather than hyperlinks, I think) to build the TOC. You have to do it manually, but once done it should maintain itself, whereas a TOC is built automatically, but must be regenerated after you edit the doc.
One caveat witih TOCs created from cross-references: Although changing the text of an x-ref source paragraph (for example from "Patatas and tamatas" to "Tomatoes and Potatoes,"and/or when the source paragraph flows to the next or previous page) update automatically or when invoking "Update cross-references," MOVING a cross-reference source paragraph to a location before or after another source paragraph, does not change their sequence in the pseudo-TOC. You'll need to manually move the reference in the pseudo-TOC to the correct position in the sequence of cross-refs. So, put the task of checking the order of x-refs in the pseudo-TOC on your before hand-off check list.

Best approach to posting to FB60: Use BAPI_ACC_DOCUMENT_POST or BDC?

Good day, everyone.
I need to develop an ABAP processing program to read an inbound file of non-PO-related invoices and post them to t-code FB60. I've spent the past day doing a lot of researching, and it looks like the two most mentioned methods I've found are using a BAPI (BAPI_ACC_DOCUMENT_POST) or just using BDC.
I've only just become familiar with t-code FB60 and posting very simple, straight-forward invoices (just data on the "Basic Data" tab along with the G/L info line(s) below; we might have to zero out the withholding tax on the "Withholding tax" tab, but not sure yet). At this point, it's not expected that the types of invoices we'll be posting will be more complex than this. Obviously, I'll be creating a report indicating any invoices that failed to post.
I'm trying to determine which route would be the best way to go. Would you use the BAPI or the BDC approach? Why that approach over the other one?
Thank you!
Dave

In continuing my research, I've just learned that FB60 is an "Enjoy" transaction, and apparently it isn't advisable to use BDC in a batch approach with any "Enjoy" transaction. Alternatives appear to be to use a BAPI or write BDC against an older (classical) version of FB60. I'll look into these possibilities.

Best approach for performing DMLs using stored procedures

Hi,
I have a really general question and would like to hear your say about this.
I want my application to manipulate or read data using stored procedures (or packages in that manner) and not directly using queries against the DB.
Let's say I have a table with many columns:
create table test (pkid number(10),col1 varchar2(30), col2 number(10), col3 date,...);For such a DML procedure, is it best to do something like
procedure do_update(i_pkid IN number,i_col1 IN varchar2, i_col2 IN number, i_col3 IN date,...) as
begin
   update test
   set col1=i_col1,
        col2=i_col2,
        col3=i_col3...
   where pkid=i_pkid;
   commit;
end;Or do a selective update, meaning update only a certain column every time, given only 1 column actually changes? (and how to do that - separate procedures for each column? [columns can be nulls])
Also, is it better to work with test.col1%type instead of specifying the data type in the procedure?
And one last question - If I have a table with 100 columns and I don't want to create a procedure with 100 parameters - the best approach would be to use a record?
I just need to be set on the way I start implementing things in order to do it well from the start.
Many thanks.

One last clarification (although it may be more related to c/c++ developers - maybe one of you will know):
We are working with C++ and VB against a SQLServer and my part is to translate all the existing procedures to Oracle in order to migrate the application to work with Oracle DB.
The existing procedures use an IN parameter for each column in the table and I would really like to use rowtype like you mentioned.
Since I'm not a c/c++/vb developer - is there an easy way of working with such types, or even User-Defined Types, from c/c++/vb (as in passing a rowtype record from c++ to a SP ?)
I'm not looking for the actual way - just want to know how hard it would be and how much code needs to be changed in order to be able to convince the developers that this is the RIGHT way to work.
PS. none of our developers have experience with ORACLE so they wouldn't know the answer...Not actually an Oracle server-side (SQL language or PL/SQL language) question - but a client one. And it has been a long time since I wrote a fat client using C/C++ or Delphi.
The OCI (<i>Oracle Call Interface</i>) supports advance (user defined) SQL data types. Has since Oracle 8i. So in that respect, yes the client can support custom SQL data types.
How well it does depends entirely on that client language's features wrt OCI integration. For example, Delphi 4 was release around Oracle 8i and supported custom SQL types. I would expect that most languages today (like Java and C#) will provide support for it.
As for usiong +%ROWTYPE+ - this is a PL/SQL clause as far as I know. Unsure whether it is supported by the OCI. What could support it is a pre-compiler like Pro*C. These enable you to mix pseudo SQL source code with client language source code. The pre-compilation step then replaces the pseudo SQL code with native client language calls to the OCI. The code is then compiled by that client language's compiler. Pre-compilers can pull all kinds of interesting "tricks" with their pseudo SQL code support.
The best would be to consult the applicable client language's manuals that describe the interface it supports (via OCI) to Oracle.
