AC Plug (a.k.a. Duck Head) Design Suggestion

This is a design suggestion for apple's laptop power adapter. The current (2005) adapter design has a removable ac plug, a "duck head". The plug is removed when one wants to use a different country's plug type, or when the power cord extension is used. I often use the power cord extension, so I often remove the duck head. Recently, I lost the plug and cursed the duck head who designed it.
My suggestion is to put a female powercord plug next to the duck head on the side of the adapter. This way, I'd be able to simply unplug the cord when I travel and never touch the duck head.

The other end (the side which plugs into the computer) needs improvement in my opinion. It could have been more user friendly if it had a 90 degree "L" shape so it wouldn't stick out straight. When used in lap (like it is intended for) if you spread your legs a bit, the weight of the computer is supported by the power plug. It may fail earlier than it's intended assuming the female part of the plug is directly mounted on the circuit board. My two cents...

"Duck Head" plug for iphone

Hi all,
I bought my iphone overseas (Hong Kong) and realized that the "duck head" plug for the AC adapter is not suitable for the wall plug in the US. Is there a way for me to buy the correct US compliant wall plug "duck head"? Thanks.

Apple store has them. Just don't tell them you bought your phone in HK

AC Power cord with duck head question, difference?

Just never understood, you've got the white square with the cord that goes to the MBP (which has the light on it), then you get the extra "duck head" cord. Is there a reason to use it other than just extending the reach of your power cable? What is the purpose of three plug cord vs just the two prong attachment on the white block? Is it to ground? I only use the white brick with cord into a surge protector (that is grounded). Just curious as to the reasoning....

so what you are saying is that it is better to use the extra "duckhead" cord from the white power square thing regardless..
Based on experience, I use the 3-prong cord all the time. The reason is that I used to leave the 2-prong hinged duckhead attached, and what happened is that the prong hinge inside wore out and started arcing and failing, and eventually died in hazy smoke and brown scorched plastic. Another duckhead I had for an old iPod USB adapter was so intermittent you had to have it just so or the charge light would not come on, and it was out of warranty so Apple wouldn't replace it. I've concluded that the hinged duckhead is far less reliable simply because it has a moving part. And the way plugs get used, you're always straining that poor little prong hinge that your entire power supply is dependent on, by hanging that big power brick from it, and of course it gets tugged and torqued until one day...
The extension cord never gives me trouble; since I usually don't need the whole cord I tie up a portion of the length. I keep the 2-prong in my bag for the rare times I need to plug into an old ungrounded outlet.

Duck head AC adapter

Hi,
I travel a lot to the US and buy my Apple gear there. But, since I live in Europe, I need a different duck head on my chargers in order to be able to charge my book pro, ipod and iphone in European sockets. A travelkit might be a logical solution to some, but then I need to buy a few kits, making it quite expensive.
I heard it is possible to get loose European duck heads, question is where? Don't want cheap chinese stuff that doesn't fit properly, tried that already unfortunately. Can anyone get me an address / website where I can buy the real Apple duck heads seperately?
Thanks,
Hans

Rather than buying a duckhead, it's easier and cheaper to purchase an AC-prong adapter, into which the duckhead plugs.

If you're running Java 7, then in System Preferences > Java > Java Control Panel in the Security tab there is a check box to enable Java in your browser. To check for update go to the Update tab.

Design Suggestion(s)

Hi all,
I was wondering if anyone has any design suggestions for the following.
I am making a simulation that permors 10000 turns (so it make 10000 calls to a function).
I have made a gui that contains a start and pause button in hopes that I can click on start to excute the 10000 calls, and click on pause to pause the program and keep the same iteration that it's on (ie if i start the program, run 100 turns, and then pause it, when I unpause it, I want it to continue where it left off).
My question is:
in order to do this should I make a thread once i click on the start button??
or should i avoid threads all together?
Any other ideas/suggestion would be much appreciated.
Thanks.
P.S. I don't need people to submit code (although i wouldn't object to it). You can just merely suggest ideas.

from what I understand about threads is this:
once you make a thread, it's like you are running a spereate program from the original one, that peroms a task, but then when it dies, all of its values are erased (ie the thread does not update the original programs values). Afterwards the original program has no means of getting these values unless the thread wrote them to a text file, etc..
am i incorrect? is there an easy way of doing it?

Hi Cathie,
What Brad explained above is that when you want to use the hosting and mail services provided by an external party e.g. Godaddy (not Business Catalysts) you need to create an A Record, using your hosting provider tools, that points to the data center where your site is located. Please find below the IPs for each data center:
54.252.148.183 or 54.252.148.191 for sites on the Australia data center
54.236.190.114 or 54.236.189.64 for sites on the United States data center
54.246.209.120 or 54.246.209.119 for sites on the European Union data center
So firstly you need to log in to the admin of your site and add the domain to use external hosting services - http://screencast.com/t/iV00iojmFfP
Then you need to create an A Record at your hosting provider that points to the IP shown in our DNS tool (as shown in the screenshot from above).
Please note that you need to create A Records for both @ and WWW records. For further assistance on this matter I suggest contacting your hosting provider as each one has their own workflow in terms of creating this records.
I hope this helps!

I Need To Know All Programs/Plug-ins/Files Bundled With CS2 Design Standard Suite

I am the Unit Software License Manager for my office at a government installation. I am in charge of accounting for all licensed software (both the physical CDs and the licenses/serial #s/Registration #s) being used on the computers in my office. Currently, I have a master list that shows all software used, including the main programs, plug-ins, add-ons, settings, toolkits, servers, drivers, etc., on all our stations. I need to break the list down to show which of these programs, etc., were bundled to the CS2 Design Standard suite specifically. Does anyone have any knowledge of the complete list that was bundled with CS2 Design Standard? Thanks.

Can't install Adobe DNG Recover Edge plug-in (Info.lua: bad header in precompiled chunk)

Hello,

I just got the exact same problem with a brand new installation of LR 4.4. Has anyone got a solution to this. It's very frustrating to see that this problem has been around and apparently not addressed for so long.

Can I hot swap the heads on a duck head adapter?

I want to string the AC cord behind a desk, but I want to be able to periodically switch between my MBP power supply and a USB one for my iPad.
Can I swap the heads while it's plugged in?
Thanks!

Yep.

Header Design question...

Anyone know how to recreate the wavy white header area this site uses? http://yogurberry.com.au/index.html
(seems you need to copy/paste link as it won't work otherwise)
thanks!

Hi
This is basically an image fill extended to x axis.
Like, you can place a rectangle and fill then use wave image and place that along x-axis below the rectangle.
This would bring the same effect.
Thanks,

IBook design suggestion for Apple

For background, I've spent many years in the PC [but not Windows] world, and done plenty of work inside those spaghetti cable boxes. When I added a hard drive to my dual G5 powermac, I was duly impressed by the clean, elegant design, inside [!] the box.
Meanwhile, I realized the time had come to put a bigger hard drive into my iBook, moving from 20 Gb in two partitions, to 100 Gb in three. There is excellent photographic advice on the web for the procedure, which is intricate but straightforward. There was the little issue of a stripped screw head, and some breath holding while I used a power drill to turn a phillips into a flat head.
But all is well. Firewire target mode disk image and restore made that part of the process very simple, if time consuming. The new drive is faster and has a 16 Mb cache on board, so the iBook is more responsive.
To the point of this subject:
For some reason, the hard drive is buried in the bowels of the iBook, behind a wall of many many screws, phillips and torx head, to unscrew and screw, and cables to unplug and plug. Of all the hardware in there, the hard drive is probably the most likely to fail and need replacement.
It should be EASILY accessible!!!
For example, it could slide on rails similar to the ones that now hold it, and come out through a panel in the side where it sits. A panel that could be held by two screws [to make one think about opening it] and no more [to make it easy and quick].
Flipping out the keyboard to install an airport card takes 5 minutes. Replacing a hard drive should take no longer. It would save Apple techs a lot of time, too.
I'd like Apple to sprinkle some of that elegant design pixie dust onto this.
Please.

This is a user-to-user to forum, so it is unlikely that Apple will read your suggestion here.
Try using the Feedback Form. In the PowerBook drop-down menu, you will find the iBooks listed. Leave your suggestion there. I would have already upgraded my hard drive if it were as easy as it is on a Windows laptop.

Design Suggestion for a new setup for a small office

File-to-Idoc complete design suggestion

Hi all,
Could anyone suggests and validate the following approach.
design:
Sender file adapter communication channel will be used to pick up the file from the ftp. File adapter polls into ftp directory and pickup the right file and archived the file into archive directory. Adapter module checks the consistency of file and allows processing the file in XI. Java mapping program is used to segregate records into correct records and erroneous records. By using BPM, success message will be configured to send SAP as an Idoc message by receiver Idoc adapter communication channel. Error message, as an attachment will be notified to the specified system administrator by mail adapter configuration.
1) Adapter module checks the consistency of file and allows processing the file in XI.
This module will be used to reject the file if Header not present. Sets the error flag to the payload. This error flag is read in the condition in the receiver determination step and the message is sent to a receiver that will handle error messages. Mail adapter then sends this message via e-mail to the administrator. The mail content consists of the erroneous payload, erroneous file name and the error records. The processing is stopped here.
Q) How can I handle the output of adapter module in Java mapping? Shall I design the source message like the output of adapter module or some thing?
Q) How can I handle this process in BPM?
2) Java mapping program is used to segregate records into correct records and erroneous records. Is the Java mapping program output will be input to that graphical mapping or something?
Q) How can I handle the success and error records of java output.
Q) How can I handle this process in BPM?
Q) How can I configure the receivers based on the conditions set by Java services.
Thanks in advance,
venu.

Hi Krishnan,
You need to pass the control record.
Std code checks whether the first record is a control record and then on tries to fetch the other details.
I suggest one debug of IDOC_INBOUND_FROM_FILE or the main program RSEINB00 would help a lot.

BPEL implementation design suggestions

Hi all,
Being new to SOA, I'm not really sure whats best practice regarding BPEL and certain problems. I just think that the way I have implemented a BPEL solution is "ugly" and was hoping there was a better solution. So I hope some of you may have some design experience you would share. :-)
We have a legacy system that gives us some unique document ids that we need to use when creating new documents. The problem is that the new system has to be up 24/7 and the legacy system is down for maintenance every night for about 6 hours.
As we are using SOA for the document creation, I have created a BPEL process that retrieves 20000 ids from the legacy system. When we need an id we ask the BPEL process for an id. When there is under 100 id's left, I retrieve 20000 more from the legacy system.
I have implemented this as following:
1. Load 20000 id's via a webservice.
2. Save the 20000 id's in a local database via a database adapter (allows me to get id's from a local database when legacy system is down).
3. Load 1000 id's via a database adapter (into memory).
4. Assign the 1000 id's into a Global variable of the same message type as the Collection used by the database adapter.
5. Each time the BPEL process is called, return the first id and mark it as used (couldn't find out how to delete an entry).
Step 1 and 2 are only called if there are less that 100 id's left in the local db.
The problem is that since the BPEL process returns each time (synchronized webservice process). Its not really a in memory queue system as it will load 1000 id's from the database each time instead of using the memory. I might as well just load one id from the db each time.
If this was Java, I would just load 1000 id's into an arraylist and add more to the arraylist from the db when needed. This would avoid to many db calls.
So how would you implement this i BPEL?
many thanks,
William

Ok guys, Here is one quick example of what i would ideally like to achieve.
[http://i279.photobucket.com/albums/kk128/ziggy_76/onelayerprocess.jpg|http://i279.photobucket.com/albums/kk128/ziggy_76/onelayerprocess.jpg]
Everything above the shaded line already exists so i will be developing new components below the shaded line. (i.e. there is already a process that reads from the database and writes to the relevant queue.
The diagram shows that each ftp server will have two processes associated with it. An INftp and OUTftp process. The IN process will be polling the relevant ftp server and writes whatever it reads back into the queue. The OUT process will be checking the queue to see if there are any new items that need to be transffered to a server. Each item in the queue has an IN or OUT flag.
I am wondering whether it is more efficient to use the above approach, or include a new process that reads from both queues and sends the requeust to either the IN or OUT processes which a normal objects.
How would a plugin be used in this situation? If there is a generic class for putting files into an FTP server, does this mean all the PUT processes will need to extend this class? How would i deal with situations where the "putting" requires different logic for each server?
I am thinking that maybe only the logic for "putting" and "getting" should be generic but the preparation should be independent?
And also, what is more efficient to use in terms of performance a java thread or an instantiated object?
Thanks
