Trying to understand the issue

Under 10.5.1 I used TM to back to a external USB drive off my PC. It worked fine. Along comes 10.5.2 and that fails. Finally heard about creating the sparse image on my machine and copied it to the drive and then the backups went well again. Unfortunately this was about 1 week before 10.5.3. Now they do not work again. I finally gave up, and moved the drive over to the USB on my MacBook, reformatted and now TM is happy. Can someone explain the issues here and what the basic problem is with using TM across the network? I do not get it and would simply like to understand. Thank you!

the basic problem is that using TM over a network is not officially supported except for backing up to disks attached to Time Capsule. there are various hacks to get around that but they are just that - hacks. updates are not tested to see if they break those hacks and any update can break any one of them at any moment. this being said, I haven't heard of 10.5.3 breaking this particular hack.
did you use [this procedure|http://www.macosxhints.com/article.php?story=20080420211034137&query= Time%2Bmachine] to set up your TM?

[SOLVED] Trying to understand the "size on disk" concept

Hi all,
I was trying to understand the difference between "size" and "size on disk".
A google search gave plenty of results and I thought I got a clear idea about
it.. All data is stored in small chunks of a fixed size depending on the
filesystem and the last chunk is going to have some wasted space which
will *have* to be allocated.. Thus the extra space on disk.
However I'm still confused.. When I look at my home folder, the size on disk
is more than 320 GB, where as my partition is actually less than 80 GB, so
I guess I'm missing something.. Could somebody explain to me what does
320 GB of 'size on disk' means?
Thanks a lot in advance..

Hi all,
Thank you for your replies.. My file manager is indeed pcman fm and
indeed it seems to be an issue.. In b4data's link the last post reads:
B-Con wrote:
FWIW, I found the problem. (This bug is still persistent in v0.9.9.)
My (new) PCManFM bug report is here: http://sourceforge.net/tracker/index.ph … tid=801864
I submitted a potential patch here: http://sourceforge.net/tracker/?func=de … tid=801866
Bottom line is that the file's block size and block count data from the file's inode wasn't being interpreted and used properly. The bug is in PCManFM, not any dependent libraries. Details are in the bug report.
Since PCManFM is highly used by the Arch community, I figured I should post an update here so that there's some record of it in our community. Hopefully this gets addressed by the developer(s) relatively soon. :-)
I guess that pretty much explains things.. And I think I did understand the 'size on disk' concept
anyway
Thanks again!

Trying to understand the sound system

Here's my problem. My mic didn't work (neither the front mic nor the line-in in the rear), so after some research and trial and error I found that if I do
modprobe soundcore
my mic works on both the jacks
But here's where my confusion lies. This is the output of lsmod |grep snd before probing explicitly for soundcore
[inxs ~ ]$ lsmod |grep snd
snd_hda_codec_analog 78696 1
snd_hda_intel 22122 1
snd_hda_codec 77927 2 snd_hda_codec_analog,snd_hda_intel
snd_hwdep 6325 1 snd_hda_codec
snd_pcm_oss 38818 0
snd_pcm 73856 3 snd_hda_intel,snd_hda_codec,snd_pcm_oss
snd_timer 19416 1 snd_pcm
snd_page_alloc 7121 2 snd_hda_intel,snd_pcm
snd_mixer_oss 15275 2 snd_pcm_oss
snd 57786 8 snd_hda_codec_analog,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm_oss,snd_pcm,snd_timer,snd_mixer_oss
soundcore 6146 2 snd
[inxs ~ ]$
So as you can see, soundcore's already loaded, so why do I have to explicitly load it again to get the mic to work?
Once I add soundcore to my MODULES array and reboot, the lsmod output is also the same as above.
So my question is -- what does the explicit loading of soundcore do, that is not done by auto-loading of that module?

Oh... since your topic is Trying to understand the sound system, that puts you (and me) inside the whole world's population... chuckle. But I thought I'd pass along a document written by probably "The" main ALSA developer that I totally stumbled across just 3 days ago.
Go here:
http://kernel.org/pub/linux/kernel/people/tiwai/docs/
and download the flavor of your choice of the "HD-Audio" document, or simply view it online. It documents the deepest dive into the current ALSA snd_hda_* layers and issues that I've found to date (but still leaves me wanting).
Why that document isn't plastered across the interwebs is beyond me. I only get 11 hits when I search for it... such are the secrets of the ALSA world I guess.

Trying to Understand the PostSyncCleanup parameter

I've got a problem with running my application on the Australian version of Windows. We have a "test" application built around SQL Server Compact Merge Replication Library (thanks ErikEJ) and that works but our application doesn't.
One of the main differences with our application code is that we do not set the PostSyncCleanup value to anything and the library sets it to 2 per this link:
http blogs.msdn.com/b/sqlblog/archive/2009/04/15/sql-compact-performance-postsynccleanup-to-turn-off-updatestatistics-during-initial-download-of-sql-compact-replication.aspx (put the :// back to get the link)
I'm trying to understand the impact of making that our "production" configuration since we haven't been using it. The description looks harmless enough but I don't really understand what statistics I'm turning off and what the impact
would be and what even the default setting is. Anything that could enlighten me would be appreciated along with a guess as to why that might be causing a problem on the Australian version of Windows would be appreciated.

So we've been running with the default value (0) and have not really had any "problems". I haven't done any testing but I'm ok with faster, like everyone would be, but am also a bit risk averse so want to know what exactly I'm turning off.
I also saw this advice from Rob Tiffany:
Use the appropriate x64, x86 or ARM version of SQL Server Compact 3.5 SP2 to take advantage of the
PostSyncCleanup property of the SqlCeReplication object that can reduce the time it takes to perform an initial synchronization. Set the
PostSyncCleanup property equal to 3 where neither
UpdateStats nor CleanByRetention are performed.
Here: http robtiffany.com/microsoft-sql-server-compact-3-5-sp2-has-arrived/
So, is the best advice to use that parameter and set the value to 3 or 2
I don't really know what I'm losing to "not performing" UpdateStats or CleanByRetention and does making that change need I need to do something else on the server or client to "clear out" or "clean up" something that this is
doing.

Trying to understand the code???

Hi,
I am trying to understand the following bit of code, currently the code puts each catalogue into a different row of the table but i want each catalogue to be put in the next column
(so the catalogues appear across the page on the actual web page). The following code is for the page in question but im not sure how much is relevant so i will paste it all and highlight the section i think is relevant:

   String resourcePath = bean.getResourcePath(null);
   String title = "Product catalogue";

You've probably already seen these, but here are a couple of links that may help.
http://help.adobe.com/en_US/FlashPlatform//reference/actionscript/3/operators.html#array_a ccess
http://www.adobe.com/livedocs/flash/9.0/ActionScriptLangRefV3/Array.html
What's basically happening is that the "for" loop goes through each item in the array. Don't be confused by the fact that two of the items in the array are Strings and one is an Integer - variable i being a String has nothing to do with the data type of the elements in the array.
The following code:
private function createLabels():void
     var myArray:Array = ['one', 'two', 3];
     for(var i:String in myArray)
          trace("i = " + i);
          trace(myArray[i]);
gives the following results:
i = 0
one
i = 1
two
i = 2
3
From that we can see that the "for" loop is assigning the index number of each array element, not the actual array element ('one', 'two', or 3) to the variable i. So calling myArray[i] is the same as calling myArray[0] the first time through the loop. This type of "for" loop is just a shorter way of doing the following, which produces exactly the same results:
private function createLabels():void
     var myArray:Array = ['one', 'two', 3];
     for(var i:int = 0; n < myArray.length; i++)
          trace("i = " + i);
          trace(myArray[i]);
Hope that helps.
Cheers!

Trying to understand the basic concept of object oriented programming.

I am trying to understand the basic concept of object oriented programming.
Object - a region of storage that define is defined by both state/behavior.
( An object is the actual thing that behavior affects.)
State - Represented by a set of variables and the values they contain.
(Is the location or movement or action that is the goal that the behavior is trying to accomplish.)
Variables- (What does this mean?)
Value - (What does this mean?)
Behavior - Represented by a set of methods and the logic they implement.
( A set of methods that is built up to tell's the how object to change it's state. )
Methods - A procedure that is executed when an object receives a message.
( A very basic comand.For example the method tells the object to move up, another method tells the method to go left. Thus making the object move up/left that combination is the behavior.)
Class - A template from which the objects are created.
( I am very confused on what classes are.)
- The definitions of the words I obtained from the "Osborne Teach Yourself Java". The () statements are how I interperate the Mechanisms (I do not know if Thats what you call them.) interact with each other. I understand my interpretation may be horribly wrong. I will incredibly appreciate all the support I may get from you.
Thank you

Object oriented programming is a replacement for the older idea of procedural programming (you can research procedural programming in google). As I understand it, in procedural programming, you have a step by step set of function calls to accomplish some task. Each function receives a data structure, manipulates it, and passes it to the next function. The problem with this is that each function preforms some action for the overall task and can't easily be reused by some other task. Its also harder to read the flow of what is happening with raw data structures flying all over the place.
In object oriented programming, an object calls a function of another object and receives back, not a data structure, but another object. Objects contain a data structure that can only be accessed by its functions. An object is not so much a sub component of a bigger task, as it is a service that any other task can use for any purpose. Also, when you pass an object to the caller, the caller can ask questions about the data structure via its functions. The developer doesnt have to know what the previous function did to the data by reading up on any documentation, or having to reverse engineer the code.
I suggest the best way of learning this is to code something like a library object.
A library object contains a collection of book objects
A book object contains a collection of chapter objects
A chapter object contains a collection of paragraph objects
A paragraph object contains a collection of sentence objects
A sentence object contains a collection of word objects.
Add functions to each object to provide a service
Example: A library object should have a:
public void addBook(Book book)
public Book getBook(String title)
public boolean isBookInLibrary(String title)
The key is to add functions to provide a service to anyone who uses your object(s)
For example, what functions (service) should a paragraph object provide?
It shouldn't provide a function that tells how many words there are in a sentence. That function belongs to a sentence object.
Lets say you want to add a new chapter to a book. The task is easy to read
if you write your objects well:
Sentence sentence1=new Sentence("It was a dark and stormy night");
Sentence sentence2=new Sentence("Suddenly, a shot ran out");
Paragraph paragraph=new Paragraph();
paragraph.addSentence(sentence1);
paragraph.addSentence(sentence2);
Paragraphs paragraphs=new Paragraphs();
paragraphs.addParagraph(paragraph);
Library library= new Library();
library.getBook("My Novel").addChapter("Chapter 1",paragraphs).
Now, lets say you want to have a word count for the entire book.
The book should ask each chapter how many words it contains.
Each chapter should ask its paragraphs, each paragraph should ask
its sentences. The total of words should ripple up and be tallied at each
stage until it reaches the book. The book can then report the total.
Only the sentence object actually counts words. The other objects just tallies the counts.
Now, where would you assign a librarian? What object(s) and functions would you provide?
If written well, the project is easily extensible.

Trying to understand the Serialization interface

Im trying to understand the Serialization of objects?
As an example, I create a Library class that implements Serializable, that stores a collection of Book objects
If I am only looking at saving a Library object to file, does the Book class require Serialization also or just the Library?
I have read the API on serialization, no answer there, if it is it's not easy to understand or read into the API...

There are some really important things to know about when doing serialization. For example one important thing to know about that not is mentioned here is that your serializable classes must define its own private static final long serialVersionUID because if you not do that will you not be able to deserialize (read in) the data you have saved later if you change anything in your serializable class. It is a bit tricky to manage files to which you have serialized different versions of your class, that is versions where you have added more serializable members to the class after you have serialized files. Well, it is not a problem if you don´t care if you have to type in all your saved data again every time you change anything instead of deserialize it (read it) from your file of course :)
Situations like this may be handled if you define your own (private) writeObject(ObjectOutputStream) and your own readObject(ObjectInputStream) methods in your serializable class but there is a better a lot smarter way to handle this. Use of a serialization proxy! how to use that is described in the excellent book Effective Java 2nd ed. With a serialzation proxy for every serializable version of your class (where a version corresponds to a version of your class with differences in its number of serializable members) may your class deserialize data written from elder versions of your class also. Actually is it first since I read the last chapter of Effective Java that I think I have myself begin to understand serialization well enough and I recommend you to do the same to learn how to use serialization in practice.

UTL_HTTP.end_of_body Exception Error. Trying to Understand the Reason Why?

I have the following PLSQL Function that returns a End_of_body Error. This started when we migrated from 10g to 11g. It is simple enough to capture so the error does not stop the Function Flow, but the error causes the OCI driver in OBIEE to error, which prevents the use of OBIEE IBOT to execute. Trying to understand why this error is occurring..not sure if we have a permissions issue on the UTL_HTTP Package or what?
Anyone seen this problem in 11g? Suggests on resolving would be great. Thanks.

Trying to understand the B_EO_INBOUND_PARALLEL ?

Bonjour a tous et a toutes,
We have 15 integrations scenarios.
-> ¾ are Async (JMS / IDOC & IDOC / JMS)
-> ¼ are Sync (JMS / RFC to CICS and return in JMS)
We are trying to give priority to the Sync scenarios in order to avoid a timeout on the sender side.
Here are the EO parameters we are using (in DEV for now):
EO_OUTBOUND_PARALLEL = 5 B_EO_OUT_PARALLEL = 20
EO_INTBOUND_PARALLEL = 3 B_EO_IN_PARALLEL = 20
So we get (in SMQ2), 3 inbound queues and 5 outbound queues. This is working correctly.
What do not seem to behave the way it is documented are the B_EO _ parameters.
My understanding is that all in inbound messages will be equally distributed in the 3 inbound queues with a maximum of 20 messages in each and every queues, for a maximum of 60 messages being process in parallel.
Idem, for the 5 outbound queues (20 messages each = 100 messages being processes in parallel).
We are not getting this type of behaviour Instead, we get more than 3 inbound queues (and more than 5 outbound queues) with weird names
Is this because we are getting more messages than 60 inbound messages ?
Back to my initial request ... prioritize Async messages. We have used message filtering to achieve that I have 2 questions
1) De we have to set filtering for OUR ENTIRE Async message to a lower priority queue and assign ALL Sync message to a higher priority queues? Is that how we should proceed?
2) How can we make sure (when we watch SMQ2) that message that are sent to a higher priority queue are getting process BEFORE a lower priority queues ?
Any help will be greatly appreciated!!

Hi David,
First of all Many thank for your answer! It seem that there is not that much peoples that has work with parameters
I have checked the OSS note you are mentioning. We will install it and test it. It might resolved other issues we have with queues:
SMQ2 - Status: RUNNING forever? & SMQ2 - "Transaction Executing ...." for ever ...
We have some blocked queues from time to time and the batch job (that restart the message) do the job. However, in some cases the queue (we get an error in CCMS) get blocked but has the status: RUNNING (not SYSFAIL) and it stay that way for ever until we manually unblock the queue. We have a support ticket open at SAP support.
Not sure I understand the meaning of the LOCK_MESSAGE parameter. It depend of what type of SYSFAIL you get ? This is parameter is available in our instance, but not in the documentation ... Can you elaborate, please ?
In your case, we you set the values to EO_INBOUND_PARALLEL and EO_OUTBOUND_PARALLEL both to 12, and B_EO_IN_PARALLEL and B_EO_OUT_PARALLEL to 250. Do you see an even distribution of messages in each and every queues? In our case, it seem that the B_EO parameters are not working as documented. We do not see an even distribution I have even run the pgm in debug to see how it reorg (balanced) its queue
Yes, we have set the BALANCING parameter is to 1
We are on PI 7.0 SP12 HPUX with Oracle as well but in HA mode.

Hello, World - trying to understand the steps

Hello, Experts!
I am pretty new to Flash Development, so I am trying to understand how to implement the following steps using Flash environment
http://pdfdevjunkie.host.adobe.com/00_helloWorld.shtml
Step 1: Create the top level object. Use a "Module" rather than an "Application" and implement the "acrobat.collection.INavigator" interface. The INavigator interface enables the initial hand shake with the Acrobat ActionScript API. Its only member is the set host function, which your application implements. During the initialize cycle, the Acrobat ActionScript API invokes your set host function. Your set host function then initializes itself, can add event listeners, and performs other setup tasks.Your code might look something like this.
<mx:Module xmlns:mx="http://www.adobe.com/2006/mxml" implements="acrobat.collection.INavigator" height="100%" width="100%" horizontalScrollPolicy="off" verticalScrollPolicy="off" >
Step 2: Create your user interface elements. In this example, I'm using a "DataGrid" which is overkill for a simple list but I'm going to expand on this example in the future. Also notice that I'm using "fileName" in the dataField. The "fileName" is a property of an item in the PDF Portfolio "items" collection. Later when we set the dataProvider of the DataGrid, the grid will fill with the fileNames of the files in the Portfolio.
<mx:DataGrid id="itemList" initialize="onInitialize()" width="350" rowCount="12"> <mx:columns> <mx:DataGridColumn dataField="fileName" headerText="Name"/> </mx:columns> </mx:DataGrid>
Step 3: Respond to the "initialize" event during the creation of your interface components. This is important because there is no coordination of the Flash Player's initialization of your UI components and the set host(), so these two important milestone events in your Navigator's startup phase could occur in either order. The gist of a good way to handler this race condition is to have both your INavigator.set host() implementation and your initialize() or creationComplete() handler both funnel into a common function that starts interacting with the collection only after you have a non-null host and an initialized UI. You'll see in the code samples below and in step 4, both events funnel into the "startEverything()" function. I'll duscuss that function in the 5th step.
               private function onInitialize():void { _listInitialized = true; startEverything(); }

Trying to understand the getResource method

Hi!
I'm writing a simple game and I'm using a game framework for java. The framework uses the getResource("path") method on creating every texture. The constructor only accepts the relative path. My problem is I don't want image files to be placed in the build folder. I would like to create textures from an absolute path. I don't want to modify the framework code.
In the Class Loader javadoc I've found that getResorce method executes the findResorce method if it fails on finding the resource. The findResource method should be overriden in a Class Loader implementation. How can I do it?
Thanks.

Thanks.It does this so you can JAR your application, which gives you the ability to distribute an executable with all of your resources included. So your buds will not have to worry about if they have the support files installed to run your application or not.I understand the intention, but it's rather an opposite of what I'm trying to do. In my idea the game on it's first running aks the user for a path. The path points a place where the sounds and images should by downloaded i.e. from an ftp server. On the later runnings the game already know where the images, etc have been downloaded and uses them.

Trying to understand the MODEL clause

Hi All,
I'm finally biting the bullet and learning how to use the model clause, but I'm having a bit of trouble.
The following example data comes from a book "Advanced CQL Functions in Oracle 10g".
with sales1 as (select 'blueberries' product
                      ,'pensacola' location
                      ,9000 amount
                      ,2001 year
                  from dual
                union all
                select 'cotton', 'pensacola',16000,2001 from dual
                union all
                select 'lumber','pensacola',3500,2001 from dual
                union all
                select 'cotton','mobile',24000,2001 from dual
                union all
                select 'lumber', 'mobile',2800,2001 from dual
                union all
                select 'plastic','mobile',32000,2001 from dual
                union all
                select 'blueberries','pensacola',9000,2002 from dual
                union all
                select 'cotton', 'pensacola',16000,2002 from dual
                union all
                select 'lumber','pensacola',3500,2002 from dual
                union all
                select 'cotton','mobile',24000,2002 from dual
                union all
                select 'lumber', 'mobile',2800,2002 from dual
                union all
                select 'plastic','mobile',32000,2002 from dual
                union all
                select 'blueberries','pensacola',9000,2003 from dual
                union all
                select 'cotton', 'pensacola',16000,2003 from dual
                union all
                select 'lumber','pensacola',3500,2003 from dual
                union all
                select 'cotton','mobile',24000,2003 from dual
                union all
                select 'lumber', 'mobile',2800,2003 from dual
                union all
                select 'plastic','mobile',32000,2003 from dual
select location, product, year, s
from sales1
model
--return updated rows
partition by (product)
dimension by (location,year)
measures (amount s) ignore nav
(s['pensacola',2003] = sum(s)['pensacola',cv() > cv()-1])I would have expected the measures clause to return the sum of all amounts for pensacola where the year > 2003 - 1 = 2002. which would make the total for [blueberries,2003] = 1800, but instead it comes out as 27000, apparently summing all values for blueberries for that partition.... equivalent to sum(s)['pensacola',ANY].
how would I go about making s['pensacola',2003] = the sum of itself plus the previous row?
I realise I can do
s['pensacola',cv()]+s['pensacola',cv()-1]but I'm really trying to understand why what I have doesn't appear to work the way I expect.

Because
(s['pensacola',2003] = sum(s)['pensacola',cv() > cv()-1])
means
(s['pensacola',2003] = sum(s)['pensacola',cv(year) > cv(year)-1])
means
(s['pensacola',2003] = sum(s)['pensacola',2003 > 2003-1])
means
(s['pensacola',2003] = sum(s)['pensacola',2003 > 2002])
means
(s['pensacola',2003] = sum(s)['pensacola',year is any])
s['pensacola',cv()]+s['pensacola',cv()-1]
means
sum(s)['pensacola',year between cv()-1 and cv()]

Trying to understand the Mac world

I've had my IMac for nearly 2 years now but have struggled all the way to migrate from a Windows environment. There seem to be so many hurdles to overcome, not least due to the horribly closed Mac universe which has made accessing things like music files, and sharing documents, incredibly difficult.
I've tried the One to One service, and asked questions at the Genius bar and via the Helpline, but rarely get a useful answer. Nice people sure, but I feel I'm dealing with staff that have been weaned on Apple (through Ipods etc) - they know a fair bit about Macs, but seemingly very little about Windows and therefore of limited help in getting from one to another. Try asking someone about FLAC audio files for example . . .
Some of the sort of issues I'm struggling to sort out include;
1) In Windows I can use the F4 key to 'repeat last action'. An incredibly useful feature when formatting a number of separate cells in a spreadsheet for example. Yet I can find no equivalent in the Mac world - I can't even see how I might configure my keyboard accordingly.
2) Having more than one application open on the desktop at a time. For example I open Word (MS Office for Mac), I then open Excel so I can cut and paste a few bits and pieces. As soon as I open Excel, Word minimises and zooms down to the Dock.
3) Screen sizes. Why oh why does my Mac insist on opening applications in a window it determines the size of ? For instance I open Numbers - on my 27" IMac it opens a window at best about 6" square, complete with tiny, almost unreadable fonts. Is there no way to get applications to open full screen, and in a set font size, by default ?
4) Screen resizing - I guess this is a feature of the OS (Snow Leopard 10.6) - only available in the bottom right ahnd corner. Just means more shuffling of windows about to use it effectively. Why can't screen resizing be done from any side as in Windows ?
And don't get me started on hardware - why does a 27" IMac get shipped with a tiny wireless keyboard ? Wireless is good for sure, but surely a desktop computer isn't trying to save space to the extent that ones loses the numeric keypad, and worst of all, the DELETE key (aaagagahgha). I've had to buy a wired version to get the functionality I need (along with some accesible USB sockets). And then there is the card reader that can only cope with SD, the USB sockets helpfully out of easy reach round the back (makes using a datastick a real pain) . . . .
Perhaps I shouldn't have gone down the Mac route (but now I've got an IPad too so heaven help me) . . . .

A couple of answers:
1. Microsoft Mac Office apps use command-Y for repeat last action, but that appeard to be missing from Apple's own apps, so it might be a Microsoft-specific thing.
2. The "open Excel and Word minimizes" issue is one I have not seen in something like 14 years of using them on Mac OSes on a few dozen Macs. Sorry. I honestly don't know how to do that, but it's worth asking Microsoft Support about it.
3. Traditionally, Mac apps open windows in the sizes you left them in; that is, the size at which you last saved the document. I can't think of a better convention. The exception is the new full-screen view added in OS X 10.7 (Lion); you appear to have to enable that each time you use the doc. Consider this dueling conventions: For years, I hates using Windows machines precisely because it insisted on obscuring all the other open windows with the current document, which I found terribly unhelpful, in my case based on experience from older windowing environments.
4. Lion changes resizing as well: you can now resize from any boundary of a window. Don't know, considering your antipathy to the Mac experience, if it's worth spending whatever Apple charges for Lion in your country for these last two features alone.
    If my memory serves, Apple's original wireless keyboard was a full one (home &c. keys, numeric keypad), and the delete with a right arrow key was near th ehome key, as on the wired keyboard. I'm guessing Apple's marketing and focus groups found most people who wanted wireless keyboard didn't care about the extra keys, ("I want to be able to stick this in my backpack") and vice versa for the size of the wired ones, but that is, again, just a guess. There are lots of third-0party Bluetooth wireless keybaord that work with the Mac --- and probably cheaper than Apple's (in every sense of the word "cheaper").
    You don't say which card formats other than SD you want to use, but the last micro-SD card I bought came with an SD-sized adapter, for what it's worth.
    I have to agree with the inconvenience of using USB (and FireWire, and now Thunderbolt) ports on the back of the iMac, but (a) Jonny Ives like "clean" design (sorry, bad attempt at blaming the issue on a Brit), and (b) brlieve it or not, you get used to roatating the iMac 90 degrees, craning your neck around, and inserting your bit of kit. And if you have an Apple wired keyboard, you can stick USB thumb drives into the ports at either end.
    I think most people who've used both Macs and Windows machines for a while agree that the first reaction to the "other" platform is irritation: "Why does this thing not do things the way I'm used to?" Just as I learned not to expect Windows to do things in a Mac OS-like way, I don't expect Macs to do things in a Windows-like manner. Not a great answer, but it's the way it is.
    Can't imagine this helped at all, but hope it at least cleared a few things up.
