I want to understand how crypto works.

Hi, I want to understand how crypto works and all. where i can start with. i really dont know anything about crypto. i need to understand how DC and keys and algorithims work together and how they work. pls suggest me where and with what i can start.

Since you asked on the Java Cryptography forum, I would recommend beginning with this book:

I want to understand how lyncs works, when I made video conferences with someone in my same building, if my call go to to server and then go to the person I´m calling.
Or if Lync realizes that we are in the same building so it never leaves, so it don’t generate traffic. My concern is the bandwidth consumption.
Please a I need the information.

Need a Little Help with Understanding How Layers Work in PSE

I have PSE version 5 and I am using it on a PC with Windows XP.
As I get more into editing photos, I am enjoying it, but confusion is also starting to set in. My question is about layers. When I go to edit a photo for web/email use only, I start by resizing it to 72 ppi and then reducing the pixel dimensions quite a bit. Then after that I normally go through this process of editing the photos by using normally about three different commands. One is Levels, then I may go to Shadows/Highlights, and then my last command is always sharpening. I used to do this all on one layer, but then finally learned to put each one of these editing features on their own layer so I can make changes/deletions without too much trouble.
When I started doing the separate layers, I was just making a copy of the background layer each time and then touching that particulay layer up with Levels, Sharpen or Shadows/Highlights. But I noticed that depending on the order in which the layers were placed, some changes would be obscured. If I put the Levels layer on top, and then the Sharpen layer and the Shadows/Highlight layer below that, the sharpen effect and the shadows/highlights effects were no longer there. I could only see the levels effect. The photo was still not sharp and so on. If I put the Sharpen level on top, then the photo showed the sharpen effects, but now the Levels and Shadows/Highlights effects were no longer visible.
So then I started to make a copy of the background initially, do a levels adjustment here, then, instead of making a copy of the original background layer again, I would make a copy of the layer that now has the levels changes on it. Then do the sharpen effect on this layer. This way I had all the changes on one layer as long as I put that layer as the top layer. But then I realized that I once again fI didn't have a layer with only one fix on it. Finally, I started to use an adjustment layer for Levels, put this as the top layer, make a copy of the background layer, do shadows/highlights, copy background layer again, do sharpen, and this seems to work a little better. But even with this way, depending on what order I place the sharpen and shadows/Highlights layers, one of them still seems to get obscured by the layer above it.
Can someone help me to understand how layers work in this regard. I am obviously a little confused here.
Thanks,
Lee

You really aren't working efficiently. First of all, do your editing on a full sized version of the photo, since you have more data for PSE to work on and will get better results. Use save for web to make your web/email copy when you are totally done. You can resize it down on the right side of the save for web window.
Duplicating a regular layer makes an opaque layer that obscures the layers below it. It's best to start off by not working on your original image, so that you don't have to worry if you mess up. If you're working on a copy, you can work right on the background layer, or only duplicate the layer once and apply your changes to that. So you'd apply both shadows/highlights and sharpening to the same layer.
Finally, you should use an adjustment layer for levels. Layer>New Adjustment Layer>Levels. This will put levels on a transparent layer above your image, but you will need to click the layer below it to get back to a pixel layer to apply other changes (you can't sharpen an adjustment layer, for example).

Not understanding how Wifi Works

Good morning all, so I'm not understanding how Wifi works on the 3GS. It seems to behave differently then on the 3G. If I send a video to some one and hit the sleep awake button it never goes through. It seems to only send it if I keep the screen active, and I'm not understanding how keeping wifi on drains the battery if everytime I hit the sleep button it disconnects it. It's kind of annoying, because before you could shoot off an email and it would go right through. I have noticed though that if it's on 3G it does go through. Has any one else noticed this? Thanks!

I notice sometimes when I am connected to WiFi that after I wake up the phone it takes a couple seconds to reconnect to WiFi so it does seem like the phone turns the WiFi off at some point while sleeping or at least goes into some sort of standby maybe. I don't think I have had an issue of it turning off after you hit sleep until it was done sending though. I would think that if the WiFi does turn off while asleep that it would have a sleep time after a certain amount of inactive time and not the second the screen is off.
I'm interested in finding this out as well. I havent had this issue but I do send a lot of large attachments and may need to know this for future reference.

I need help understanding how this works. AS 2.0

Its my first time here and i only started learning flash today. I aint too great with maths and i was showed this piece of code that makes a triangles point follow the cursor. It involved mathimatical things ( which i aint so great at) and the guy said "You dont need to know how it works, just how to use it." well i copied his code and it worked, but i have no idea how to use it in other rotation apart from the one he taught us. I dont even understand how to redo his code i saved it to a word document and anytime i wanted to make something rotate something in that fashion i would refer to that. But i dont want to have to do that, i want to know how to use it, dont have to understand it, but use it for other rotation matters. If you are going to help, please try to be a bit simmple i explaining it, cause im new. Dont get me wrong i aint thick but i can find it a bit hard to follow some things, that is i my current problem.
here is the rotation code:
onEnterFrame = function()
hero._rotation = getmouse(hero);
getmouse = function(mc:MovieClip):Number
dy = _ymouse-mc._y;
dx = _xmouse-mc._x;
rad = Math.atan2(dy,dx);
rotate = rad*180/Math.PI
return rotate+90
also if it helps, here is the video i was watching: http://www.youtube.com/watch?v=w3OfrpbNhHs
please if you can, explain how the entire thing works.
thanks for any help given in advance.

Hi,
Here's a short primer. It may not be sufficient but here goes.
1st, move the closing bracket at the end and put it on the third line. This makes the code more efficient
onEnterFrame = function(){                               // this causes Flash to repeatedly
                                                                          execute the next line at the
                                                                          frame rate you selected
                                                                          for your document
       hero._rotation = getmouse(hero);               // this tells Flash to rotate a
                                                                          movie clip (named hero) based
                                                                          on the function getmouse()
};                                                                     // putting the }; here makes the

getmouse = function(mc:MovieClip):Number{   // This is the function called with
                                                                         mc referring to hero that was

     dy = _ymouse-mc._y;                                // dy means delta y which subtracts
                                                                        the y position of the movieclip

     dx = _xmouse-mc._x;                               // dx = delta x (same as above line
                                                                        but on the x axis)
                                                                     // once you have the x and y sides
                                                                        you male a triangle.
                                                                        Now use trig to find the angle
     rad = Math.atan2(dy,dx);                           // the computer works in radians
                                                                        the arc tangent atan2 will give the
                                                                        angle in radians
     rotate = rad*180/Math.PI                            // you want to convert the radians to
                                                                        degrees, that's what this line does
     return rotate+90                                         // this returns the value of rotate back
                                                                        to the calling function in line 2.
                                                                        the +90 determines which part
                                                                    // of the hero movie clip is facing the

If you put the mouse cursor over any of the green reserved words above in the Actions panel you will get a desctription of what these do.
hope that helps.

How much does this cost? & I still can't understand how this work

How much does this cost? & I still can't understand how this work

Hello mkopti,
ePrint is a free feature include on most of our wireless printers that are e-all-in-one enabled. It allows you to register your printer on HP's website http://www.eprintcenter.com and create an account. Once an account has been created you can enable the web services feature, after connecting to a valid network with internet access, which will print off a registration code you can use to add the printer to your account and customize an email address for the printer. This allows you to print to the printer from virtually anywhere simply by sending an email to the printers email address and when it is received it will print.
Most of these printers are also Airprint enabled meaning you can print locally from the same network on the iPad, iPod, and iPhone (version 4.3.2 and higher) by using the built in "Print" command in the idevices.
If you have any other questions or need clarification feel free to reply to this post and I will try to answer any questions you have.
If I have solved your issue, please feel free to provide kudos and make sure you mark this thread as solution provided!
Although I work for HP, my posts and replies are my own opinion and not those of HP.

Trying to understand how beans work.

I can't seem to figure out how beans work. Or more specifically how to target different parts of a bean. I think not knowing the terminology is a big part of this confusion too.
For instance. I have a jsp file and a bean. the jsp has a form input that submits to itself. the bean gets the info that was typed in and displays is in the <%= etcetc %> tag. Now, what im trying to do is also submit that value to my mysql db. This has created numerous problems for me. For one, i don't really know how to check if it's working (other than actually looking at the DB table). The other problem is how do i target that part of the bean to tell it to do that function (again, the terminolgy eludes me).
I'll post all of the code. There is a good chance that the DB code wont work. I'm really just hoping someone can explain to me
how i call the DB function from the JSP file.
I mean, is this even possible? Or do i need seperate beans for everything?? It seems kind of silly to not be able to do this.
ok, so here is the code.
JSP:

<%@ page errorPage="myError.jsp?from=hello.jsp"%>
<jsp:useBean id="simpleBean" scope="page" class="jspbook.ch3.simpleBean"/>

<jsp:setProperty name="simpleBean" property="fname"/>
<html>
<head>
     <title>Hello</title>
</head>
<body>
<center>
     <b><%= simpleBean.welcomeMsg() %></b>
</center>
<table align="center">
     <tr>
          <td>
               <form name="sdfsdf" action="test.jsp" method="post">
               <input type="text" name="fname" value="">
               <input type="submit" name="submit" value="submit">
               </form>
          </td>
     </tr>
</table>
</body>
</html>and here is the bean
package jspbook.ch3;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
public class simpleBean implements java.io.Serializable {
   private String emplid;
   private Connection con = null;
   private ResultSet rs = null;
   private PreparedStatement st = null;
   /* Member Variables */
   private String lname;
   private String fname;
public simpleBean()
        try
          Class.forName("org.gjt.mm.mysql.Driver");
          Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/stm?user=root&password=");
    catch(Exception e)
          System.out.println(e.getMessage());
      /* Initialize bean properties */
    setLname("");
    setFname("");
/* Accessor Methods */
public String getLname() {
    return lname;
public void setLname(String _lname) {
    lname = _lname;
public String getFname() {
    return fname;
public void setFname(String _fname) {
    fname = _fname;
/* Display personalized message */
public String welcomeMsg() {
    return "Hello " + fname + " " + lname +
      ", welcome to the wonderful world of JavaBeans!";
      public void insert()
       try
            String s1="insert into commstream (commTitle) values('"+fname+"')";
            st = con.prepareStatement(s1);
            st.executeUpdate();
            st.clearParameters();
            st.close();
       catch(Exception m)
}So there it is. If someone can explain the fundamentals to me, that would be great. What would also be great is if someone can make the above code work :)
I've checked online tuts/specs on this, but to be honest im just not grasping it.

iPhoto is a relational database program
In the strongly recommended managed library (you have chosen to ignore this recommendation and use a referenced library) imported photos are copied to the iPhoto library and stored in the originals folder, a thumbnail jPEG is created and places in the data folder and when any modification is made (including autorotation) a modified version of the photo is created and placed in the modified folder. iPhoto updates its database entries to reflect everything it does.
It is critical that you do not make any modifications of any sort to the content or structure of the iPhoto library - doing so is likely to corrupt the library and cause you to lose data.
When you use the referenced mode which you are doing (and which is not recommended) you are taking total responsibility for the original photos which included not moving or modifying them while iPhoto is referencing them
Unfortunately, all pictures from a certain import has duplicated in iPhoto.... so I "moved to trash" all pictures from that import
Did you do this with the iPhoto trash? or did you use the finder to modify the contents of the iPhoto library.
If I "move to trash", I assumed it got rid of whatever index (and preview cache) to that particular JPEG. I was actually surprised it did not delete the actual JPEG but I'm ok with that.
again - iPhoto trash or finder trash. If you move a photo to the iPhoto trash and empty it all traces of that photo in the iPhoto library will be removed - nothing will be done to any file outside of the iPhoto library -- ever

Trying to understand how BTRFS works

Hello,
I read most if not all of the articles, presentations and podcasts about Btrfs at https://btrfs.wiki.kernel.org/index.php/Main_Page and other sites. All is very nice. I had to read some of the information a couple of times though to more or less understand and I'm not sure if I really do.
I'm trying to explain BTRFS in my own words, but wonder if it is correct. What about the following:
The storage space of a BtrFS file system is comprised of file data blocks and metadata blocks. The BtrFS metadata is organized in a B-tree fashion and describes the version and location of data on disk. The BtrFS file system uses a copy-on-write (CoW) storage strategy. An existing file under BtrFS is never initially overwritten. Instead, when modifying a file, data blocks are copied, modified and written anywhere on disk according to metadata to prevent overwriting of data required by snapshots. When a file under Btrfs is modified, data is not necessarily overwritten. Modified data blocks of files can be written anywhere on disk according to metadata and requirement to maintain existing snapshots. A snapshot does initially not impose additional storage space until data blocks are modified.
Is this correct? And if not, where am I wrong please?
Thanks!

Dude wrote:
Thanks for the feedback. Actually that's one of the parts I'm not sure if I understand it correctly. It is my understanding that Btrfs works on the data block level, which I think is the smallest amount of data that can be allocated. Similar to Oracle database. So in order to modify data, the whole block needs to be written. For example, let's say I change a the word "teh" to "the" in a file. Doesn't it have to read the whole block, modify the content, and check the metadata before writing the complete block?Yes. But it does tight packing, so it probably wouldn't write an entire block out for "the" -- it would just squash it into one of the leaves of the b-trees.

I just dont understand how to work photo shop HELP ME

my mom bought this for me and im reading the directions and trying to figure out how it works i just dont get it at all!!! i dont know why, im good at using computers i just nvr grasped the concept of how to work this
if you have a helpful hint please comment thank you

Adobe TV has a whole selection of free videos that should help you to get started.
http://tv.adobe.com/show/learn-photoshop-elements-8/
You can also find lots of videos using Google...

or YouTube

If you just search for Photoshop Elements (without limiting it to Photoshop Elements 8 as I did) you will get even more results...most if not all things should work in version 8. (Version 8 user interface will look different and may have additonal features as each version gets new goodies.)

I really dont understand how this works

alright first off this isnt for a school assignment so please dont feel guilty about "giving it away"
alright so this has to do with something called gridworld, if you ever seen it you know what it is, if you havents its basiclly a java built world that has bugs, rocks, flowers, and other things.
(here is a video showing the basics of gridworld http://www.youtube.com/watch?v=ZnWGOT5Bd2E&feature=related). i program in JCreator btw not greenfoot.
alright getting to the point i have the code for a bug someone build called a "chameleoncritter". what the bug does is change colors depending on what it is next to, so if it is next to a pink rock it changes pink, ive been reading the code and can honestly not figure out how this method changes its color depending on what it is next to. here is the code

Understanding how interfaces work

I am new and trying to understand the magic of interfaces. I understand that you can declare an interface as follows: public interface MyInterface {
public abstract thisHereMethod();
} But what I don't understand is how the compiler properly finds the right class from which I am drawing method thisHereMethod() from? How does it make an exact association with the "right class?"
Someone told me that it all works with namespace association. However, if that's true, what if you have two or more classes within the same namespace which all happen to have the same identifyer, yet different functionality. How does the compiler know which of these classes I'm trying to draw this method from?
I would really appreciate an explanation if someone out there knows. Thanks for your help in advance!

jverd. I think I'll have to read over what you wrote
a couple of times to really understand all the
implimentations and instantiations that must take
place, but I think I'm getting closer to
understanding. I do appreciate your explanation.
Thank you very much.No problem. You sound like you're still not really sure how to create, implement and use interfaces. For a fairly straightforward example, take a look at the Comparable interface.
http://java.sun.com/j2se/1.3/docs/api/java/lang/Comparable.html
The basic idea is this: You define an interface, giving it some methods for which all implementors must provide the workings. You also provide documentation explaining what the interface is for and what an implementor's general semantics should be.
When somebody goes to implement the interface, the compiler checks to make sure all the requried methods are present, but only high quality coding, testing, and review can ensure that the intended semantics are preserved.
Looking at Comparable again, the idea is that if a class wants to declare that any two instances can be compared to each other and that the concept of less than, equal to, greater than applies, then that class can declare "implements Comparable" on the class declaration line. It must then provide the required compareTo method, if it doesn't, the compiler will complain. It should also implement compareTo as per the contract laid out in the API docs. If it doesn't, users of the class (that is, people) will complain.
Switch perspective now to a class that's using your class, which implements Comparable. There will be a method somewhere that takes a Comparable as an argument. You can pass a reference to your class to any of those methods. Your class is a Comparable, just as it is a MyClass and is an Object, etc.
What's the use of a method that takes Comparable without knowing anything about what the actual class is? Sorting is a big one that pops to mind. If you're writing a sort routine, like quicksort or mergesort, one part of sorting is comparing two of the elements being sorted. You need to know which one is larger so you know if they're in the right order. The actual comparison is type specific. That is, how you compare two Strings is different from how you compare to Floats is different from how you compare two MyEmployeeClass objects. Except for the details of how to compare (String: compare character by character. Float: compare numerically. MyEmployeeClass: compare by employee ID or name or hire date or whatever you decide is appropriate)--except for that bit, the rest of the sort is identical. So, why write one sort routine for String, one for Float, one for MyEmployeeClass. All you need to do is write the sort algorithm with a step that says "if the comparison routine for the two items says that #1 is greater than #2, then switch them" and then make sure that whatever you're sorting has a valid comparison routine. The declaration of your sort method might look like this:
public Object[] sort(Comparable[] sortMe) {}and within the body of sort...
if (sortMe[ i ].compareTo(sortMe[j]) < 0) { /* out of order, so switch them */ }The sort algorithm doesn't have to know anything about your class--exceept that it has a compareTo method with the proper signature. Your class implements Comparable, to say that it can be used by any bit of code that expects a Comparable. The callers of compareTo only need to know that your class is a Comparable (implements Comparable), and thus is guaranteed to have that method. The VM then uses the vtable of whatever object compareTo is being invoked upon to find the correct compareTo. This vtable is bound to each class at compile time and to each object of that class at instantiation time.
Is it making any more sense yet?

Understanding how iPhoto works?

A couple of questions please...
I told iPhoto not to copy images from my source directory but it must being doing something similar as I can delete a photo in my source dir, and it will not be deleted from iPhoto. How is this working?
How does iPhoto keep in sync with my source directory? If I add another sub-folder to it with new photos do I need to manually import or something or will iPhoto look to it to see what's changed?
Thanks,
Steve

As far as I understand now, when I want to transfer photos directly from my camera into iPhoto, I should by all means use a managed library. Correct?
Yes. It's the only way to use iPhoto to transfer the photos from the camera directly.
Just an FYI
There are many, many ways to access your files in iPhoto:
*For Users of 10.5 and later*
You can use any Open / Attach / Browse dialogue. On the left there's a Media heading, your pics can be accessed there. Command-Click for selecting multiple pics.
Uploaded with plasq's Skitch!
(Note the above illustration is not a Finder Window. It's the dialogue you get when you go File -> Open)
You can access the Library from the New Message Window in Mail:
Uploaded with plasq's Skitch!
*For users of 10.4 and later* ...
Many internet sites such as Flickr and SmugMug have plug-ins for accessing the iPhoto Library. If the site you want to use doesn’t then some, one or any of these will also work:
To upload to a site that does not have an iPhoto Export Plug-in the recommended way is to Select the Pic in the iPhoto Window and go File -> Export and export the pic to the desktop, then upload from there. After the upload you can trash the pic on the desktop. It's only a copy and your original is safe in iPhoto.
This is also true for emailing with Web-based services. However, if you're using Gmail you can use iPhoto2GMail
If you use Apple's Mail, Entourage, AOL or Eudora you can email from within iPhoto.
If you use a Cocoa-based Browser such as Safari, you can drag the pics from the iPhoto Window to the Attach window in the browser.
*If you want to access the files with iPhoto not running*:
For users of 10.6 and later:
You can download a free Services component from MacOSXAutomation which will give you access to the iPhoto Library from your Services Menu. Using the Services Preference Pane you can even create a keyboard shortcut for it.
For Users of 10.4 and later:
Create a Media Browser using Automator (takes about 10 seconds) or use this free utility Karelia iMedia Browser
Other options include:
1. *Drag and Drop*: Drag a photo from the iPhoto Window to the desktop, there iPhoto will make a full-sized copy of the pic.
2. *File -> Export*: Select the files in the iPhoto Window and go File -> Export. The dialogue will give you various options, including altering the format, naming the files and changing the size. Again, producing a copy.
3. *Show File*: Right- (or Control-) Click on a pic and in the resulting dialogue choose 'Show File'. A Finder window will pop open with the file already selected.
You can set Photoshop (or any image editor) as an external editor in iPhoto. (Preferences -> General -> Edit Photo: Choose from the Drop Down Menu.) This way, when you double click a pic to edit in iPhoto it will open automatically in Photoshop or your Image Editor, and when you save it it's sent back to iPhoto automatically. This is the only way that edits made in another application will be displayed in iPhoto.

Help understand how this works

Hows everyone doing, i need some help understand this. This is my first time using Lulu. From the reviews i'v read about it they tell me this is the #1 place to come to to get my books printed. Here the question, i have all 3 of my books ready to be uploaded do i just sent that in, then they send me the prints ? or so they self them for me. Sorry if this seems like a dumb question, but its my first time using this particular site.

Here's a quick overview:
You start the new book wizard. Click "Create," pick a book type and size (hardcover, paperback, etc.; 6x9, 8.5 x 11, etc.), and click "Make this book."
Hint: If you want the widest distribution for your book, pick a size / type that has a green checkmark next to it.
The wizard will guide you to name your book, apply an ISBN (or get a free one), upload your contents, and upload your cover or design a cover. It will guide you to set pricing and distribution, and many other options.
When you've done all that, your book will be available to order. You will see two prices: the one you pay, and the one other people pay. The one you pay is the printing cost per book. It may be anywhere from $2.50 to $20.00 or more, depending on options you pick -- probably coser to the low end.
On that first page, where it says "Create," there is a calculator that will figure roughly what your book will cost (printing costs), so you can plan your options around that calculator.
So you order as many books as you want, pick shipping, pay with a credit card, and in a few days, the books are on your doorstep.
I hope that helps.

SMTP Banner mismatch - still not understanding how this works?

I have a new Exchange 2010 install.
My outgoing email is getting flagged as spam. MX Record test shows SMTP banner mismatch.
I understand that you don't change the FQDN on the receive connector using the GUI.
I have created an additional Receive connector so I have the following:
Receive Connectors:
Client Comm
Default Comm
My question is how to I change the smtp banner and which connector do I set it on. The syntax needed for the Set-ReceiveConnector is kicking my butt.
It sure is frustrating that the new Windows World is so centered around Powershell command lines. Very frustrating and backwards technology.
The documentation on the Set and Get-Receiveconnectors is very poorly written. IMHO.

My reverse DNS is setup correctly.
This is an issue with the receive connector banner page. Some email hosting services, AOL, Hotmail etc. are flagging my outbound email as junk. So they must be doing a test to see that my receive connectors have the wrong SMTP banner.
My send connector is ALSO setup correctly.
I need help with the syntax in using the Set-receiveconnector cmd.
Follow:
http://technet.microsoft.com/en-us/library/bb125159(v=exchg.141).aspx
Create a Internet type custom receive connector. My assumption is that you receive internet messages directly to the hubs. When you create an Internet Receive Connector it will allow anonymous senders to connect to it so it will work for internet messages.
In the Specify the FQDN this connector will provide in response to HELO or EHLO field, type the name advertised in response to the SMTP HELO or EHLO verb. If you leave this field blank, the fully qualified domain name (FQDN) of the Hub
Transport server or Edge Transport server is automatically added when the connector is created
