Potentional iPhone Buyer: Just some general questions

Hey everyone I was considering buying an iPhone, and was wondering if I should wait till the new iPhone OS 3 is released or can you just download when it is released for free? Also in the iPhone plans I was wondering whats included in the allocated data (Web Browsing, Maps, App Downloads, etc.)?

The current iPhones can all download 3.0 when it is released this summer.
Also in the iPhone plans I was wondering whats included in the allocated data (Web Browsing, Maps, App Downloads, etc.)?
The data plan would cover all data. It doesn't differentiate.

SAP CM25 which profile to use and why and some general questions

Hi there,
I have a few general questions, if you may share your thoughts on this.
In a manufacturing environment, is CM25 more used to finite schedule the work centers or labor or both ?
Is it a good idea to even finite schedule the planned orders or just production orders ? We want to create production orders 1 week ahead of the production schedule and planned orders gets created 3-4 weeks earlier than production order gets created.
The graphical tool seems to be slow sometimes when dispatching and doing some actions on the screen, has any one have any say on this. Should we need to have better computers on the floor for this to work ?
I have been trying my solutions using CM25 and not CM21 or CM27 using the profile SAPSFCG005, is there any other profile that I need to consider and other transactions to consider like CM21 or CM27 for certain purposes?
Thank you

Hello
In a manufacturing environment, is CM25 more used to finite schedule the work centers or labor or both ?
It can be used for both depend upon bottle neck resource whether machine or labour.
Is it a good idea to even finite schedule the planned orders or just production orders ? We want to create production orders 1 week ahead of the production schedule and planned orders gets created 3-4 weeks earlier than production order gets created.
Better it should be finite planning for planned order also you can use MRP with lead time scheduling.
The graphical tool seems to be slow sometimes when dispatching and doing some actions on the screen, has any one have any say on this. Should we need to have better computers on the floor for this to work ?
It depends upon the data load and selection,
Restrict the number of objects to be displayed, for example, select only a small number of work-centers/orders.
Customize the time profile (transaction OPD2) such that the database read period, the planning period and the evaluation period are as small as possible. As a result, fewer objects are read and displayed.
Refer KBA 2038780 - Tips for performance improvement on Capacity Leveling
If you want to process more orders, check whether a batch planning (planning in the background on transaction CM40) is possible.
I have been trying my solutions using CM25 and not CM21 or CM27 using the profile SAPSFCG005, is there any other profile that I need to consider and other transactions to consider like CM21 or CM27 for certain purposes?
It depends upon your requirements which transaction to use and which profile. You can customize your own profile also.

Just Some General Info. Questions

I was just wondering how many songs, videos, podcasts, movies etc. are in the iTunes store worldwide. The US iTunes page says 3.5 million but thats only US.
By the way, I'm posting in the mac section because I own a mac. (for those of you who wondered...)
Michael

Okay, 512MB RAM, is your issue, you need at least 1GB to run OSX with any resemblance of snappiness. Using 80% of your drive is a fair bit, but not bad. Its good to have 10% of your drive free at any given time (the system will at times use about that much for virtual memory, although maybe more in your case since you have so little RAM). You might want to start looking through your files and see what you do an don't need, since you can fill up a few GBs fast in some situations (such as installing new programs, etc.)

Some general questions about java

Hi,
I am a beginner with java and actually i am new to programming as such. i want to ask certain questions.
I read in The Java Tutorial that java is both a 'compiled' and an 'interpreted' language while most languages fall in either one of the two categories. What is the difference between a compiled and an interpreted language?
All the java programs that we right are compiled by the java compiler. So in what language was this java compiler and java VM written
What is the definition of native code. Does it depend on the operating system ? If so, is it defined by the operating system ? If I am not mistaken, an OS in itself is a huge program, so which language can be used to create an OS. For instance, can an expert in java create his own OS using the java programming language ?
These questions may sound silly but I need to know the answers

Okay, a compiled language is completely translated into object code (one and zeroes, usually) before it is run. An interpreted language is turned into object code as it runs. The object code for most languages is the ones and zeroes that make sense to the processor. The object code for Java is Java bytecode.
Java bytecode is a set of universal commands that make sense to any Java Runtime Environment (JRE or Java Virtual Machine JVM. I think they're the same thing, someone correct me if I'm wrong,). The JRE is an interpreter. Each JRE is specific to the platform, that is; there's a Windows JRE and a Solaris JRE and yada yada. The JRE interprets the bytecode commands and turns them into commands for the platform. For instance, a bytecode command is something like, "draw a window" and the JRE turns this into the Windows or Solaris command that draws a window.
I don't know what language Java was written in. It may not all be written in one language. It's very possible that the Java compiler (javac) and the java interpreter (the JRE) are written in entirely different languages. I'd suspect the answer to this can be found in van der Linden's "Just Java" book.
Native code, in Java, usually refers to legacy code, existing code written in whatever language that you wish to use in a Java program. Maybe the native code costs too much to convert; maybe it works really well, maybe it does soemthing special, whatever -- you want to use it so you use the native command in a Java program to tell Java to run this piece of code in whatever language. Native code doesn't really have anything to do with the OS other than it's code that runs on the OS you want the Java program to run on.
An OS can be written in anything you want, but some languages are better than others. I think the Mac OS is/was mostly Pascal. Wasn't C invented in order to write Unix?

Some General Questions about using SSL sockets

1 Since both SSL and TLS rely on public-key cryptography, can I use it efficiently for encrypting large amount of data transfer within a network? Or I�ll be better off using secret key.
2 If I understand correctly, I can install client/server certificate (public key) along with the software installation. Is that right? In other words, I don�t have to create them programmatically.
3 To convert our unsecured client/server application, is it enough to replace plain sockets with SSL sockets and use a self signed certificate for the server? (Ours is a closed network and we don�t require any client authentication).
4 How does SSL handles server to server communications?
5 How do you encrypt data ( some of the fields) in a text file?
Thank you all.

hey there.
1.yes you can use it to encrypt large amounts of data, and heres why:
when you use SSL, it uses public key encryption to first tranfser across a private key. then from then on the data is simply private key encrypted, which is relatively fast and easy.
2. Yes, you may chose to make them programatically or not
4. the question doesn't really make sense. In the end, what is a Server and what is a Client is up to your application. From SSL's point of view, you just have two machines with Sockets on either side that are connected. You can use SSLSocket.setClientMode(boolean) to choose which of those socket will act as the "server" for the purpose of the authentication handsake.

Some general questions about swing

Hi,
I used to do some swing development couple years back but since then I have been more involved in the j2ee scene. I have lost some touch and was wondering if some of my questions can be answered. I'd appreciate every effort.
First of all, I am trying to make an applet that can be used to upload multiple pics at the same time. Similar idea to facebook picture upload applet. My Q's are
-> can every swing application be turned into an applet? or when the developer starts writing an application he should write it from an applet POV
-> I noticed that the applet on facebook looks a lot like a window application. icons and the look and feel of the application is not that of a applets i saw couple years ago with sun java look and feel, how can this be achieved? is there some small example?
-> can someone suggest an example || tutorial of an applet that shows how to upload an image to the server?
and lastly for mental satisfaction :)
-> how hard do you think it is to build such an application. I assume it will just have a JTree on the left side and on right side it will show contents of the folder that is currently clicked.
Thanks for your time

thanks for the tutorial link.
However, the tutorial explains how to show icons from images. But what about in my case when the images arent even on the server yet.
Basically when the user is browsing files and gets to their my pics folder on the right side i want to show icons of images in that folder. for this reason i doubt I will be able to use what they've implemented in that tutorial. As the pics havnt yet been uploaded by the user i have no direct access to the images.

Njawin - jcomgen and some general questions

Hi.
I'm currently evaluating njawin, and some questions came up:
Will there be a command line interface for jcomgen?
The interactive GUI isn't really suitable for an automated build process.
njawin compared to jawin:
njawin seems to be more advanced, but there's no source available.
Does anybody know if this will change in the future?
regards,
roman

Carl,
The njawin distribution available for "evaluation" download around the web comes with no license, as it is a version of OLE for Java (OLEJA), a commercial product, which was developed before OLEJA went retail.
One thing you'll notice is that OLEJA and Njawin have remarkably similar APIs. If your application's functionality does not have very complex requirements, you can simply replace all references to "oleja" with "njawin", and all references to "compose" with "develop". This holds true for the generated .java files, the .xml file, etc. I am not sure if OLEJA introduces or uses more APIs than the ones that appeared in Njawin, but for my application, this approach was successful.
One other thing to keep in mind is that I don't see why you'd actually need to build your sources into a jar, if you simply include them in a larger package as part of your application's source code. Just put njawin.jar, njawin.dll, and yourdll.dll on the build path and the rest of your problems should be solved for you. Keep in mind that, since OLEJA is commercialized, it's been debugged a lot (as the author has stated in mailing lists) and that means Njawin could have some unexpected problems. In this case you should thoroughly test your usage of Njawin with your application to be sure it runs well in your environment. Errors that could potentially crash your JVM may appear when certain functionality (especially multi-threaded functionality) inside your ActiveX control is executed.

Some general questions about recently purchased Powerbook G4 15"

Hi guys,
I finally got my used Powerbook G4 15" A1095 1.5ghz off eBay and it's got some issues, any help would be great:
1.White areas on the screen, not to concerned about it but i can see them?
2.Some spots of dirt "behind" the screen all the way down the right edge of the display? These are not dead pixels?
3.Won't read dual layer dvd's? (i know it can't burn them)
4.Tatty case. (I have purchased a new lower case top case and lid from The bookyard for a total of £60 and i am having our It guys replace these for me to tidy it up.)
5.After buying these bits i've since discovered the lower ram slot is faulty so i'm stuck with 1gb?
6.Can the dirt behind the screen be removed when the lid is changed or are they in the display itself?
I did try and return the book to the seller but pretty much got nowhere so i'm stuck with it. On the plus side the screen has no dead pixels, is nice and bright and the machine runs pretty fast. I only use it for web surfing and music some it's fine.
Phew! sorry the the mass of questions!

Sounds like you bought yourself a project - or some else's troubles.
The internal drive won't read dual layer DVDs. They were not even invented when the PB was released.
The dirt behind the screen hints that the machine has been apart. It is possible to get the front glass off, but as eww stated it is not a fun or easy job.
The white spots sound about right for an aging Powerbook. I'm guessing you are not using it as a portable cos I'm sure the battery is smoked too. Hook it up to a nice large external display. The PBs have a powerful video card and give great color depth on a decent display.
The failed RAM slot is a killer, but common. Mine is the same. 1GB of RAM does the job, so don't give it a second thought.
Sadly, the Powerbooks are at the end of their life cycle as a portable, but they do make great desktop computers with a few peripherals. Set it up with a nice widescreen display, an external firewire DL DVD drive and a cooler pad and you should have a lot of fun with it.
Don't put Leopard OSX 10.5 on it! It will just slow it down and give you a whole new bunch of issues to address.

Just some newbie questions :)

what would happen to my macbook pro system if i didn't upgrade my OS X to the latest one everytime apple releases new one?
will it get any bug or viruses or something strange?
thx,

Installing a newer Operating System is not always an advantage. Newer OS's sometimes will not have all of the Apple applications that you may have been using and occasionally makes some third party applications obsolete.
As a general rule I suggest that if you have a 2010 MBP or earlier, stay with Snow Leopard 10. 6.8. It is the most efficient and stable OSs to date. If you have a 2011 MBP, Snow Leopard, Lion or Mt. Lion will operate satisfactorily on those MBPs. For 2012 MBPs, you will be restricted to Mt. Lion only since it is the OS that comes with the MBP.
To date there have been no viruses for MBPs for any of the OS's and there are security measures incorporated within the OS, thus no AV software is essential. Malware has been evident from time to time, but it requires user cooperation to install it. If something looks suspicious, don't install it and you should have a malware free OS.
Ciao.

Im a newbie and just some easy question

hi there guys!
i just got a g3 1book this morning from a friend and was trying out the mac os..i would like to ask if there is any chance i can delete some applications as the laptop has only 20gb of spacce and when i got it only 9gb left..is this normal? and i have downloaded the icons from thsi website so how do i change the icons?Thanx guys..looking foward to use mac from now on...once again..thanx in advance!

Hi Mackerz,
My Powerbook has a 60Gb drive, and after a year of use is down to about 12Gb. So it's pretty normal after several years of use, downloading of music and photos, to use up a lot of hard disk space.
If there are any applications that you know you're not going to use, such as Garageband, or iDVD, you can just drag them off to the trash, and that will free up a few Gigs. Before you do that, you might want to make sure you've got your install disk, so that if you ever desire to reinstall them, you can.
A nifty freeware utility that can help you see where you big files are, is called WhatSize. It can be found here:
http://www.id-design.com/software/whatsize/
To change a file's icon, click on the file/application that you'd like to change, and hit "Command I" (Command is the key with the Apple on it). This will bring up the Info window.
Now select the picture (or icon) that you desire to become your file's new Icon, and copy it with either Edit > Copy or Command C.
Now click on the icon displayed in the Info window (just to the left of the file's name). The file will get a faint hightlight around it. Select Edit > Paste (or you may need to hit Command V), and the picture/icon you had copied will now be the icon for your file.
Close the Info window, and you're in business.
Hope this helps,
Bob

Some general questions about multi-threading

Hey Everybody,
I have a dilemma with a multi-threaded program that I have written.
Well to be truthful I actually wrote the program with no consideration whatsoever for multithreading.
As a result of this complete lack of concern I get a completely hung user interface.
My program performs a lot of network communications over URL��s and also writes information from URL��s to disk. The combination of networking and I/O in my program and the fact that I have not built multi-threading into the program has lead to complete failure of the user interface. When I say complete failure I mean complete failure. If it were only button��s not responding then I wouldn��t be all that worried, however the entire drawing area of my programs ��Frame�� completely freezes. It��s cool if nothing is maximized or minimized over the frame but as soon as this happens my programs drawing area has a ��serious hang over!��.
I have begun learning about threads, in principle they sound wicked however in practice they have proven to be a brain tease (oops �K.. honesty).
The difficulty of threads should not be all that daunting to me, however I have a couple of very simple questions that I would love to have answered�K..anybody out there!!!!!!!!!
This is the normal basic method of running a thread that I have been attempting to incorporate into my program:
1). Extend the thread class,
2). Override the run() method in the subclass (created from step 1),
3). Create an instance of the subclass,
4). Call the start() method on the instance (from step 3).
I have read that every statement the thread will execute is contained within it��s run() method.
Question 1). This being the case is it possible to have member variables or methods inside a class that extends thread? Please explain!
Question 2). Can a class that extends thread contain a constructor? Please explain!
Question 3). If a subclass of thread cannot contain a constructor as I assume to be the case then how can code executing within the newly spawned thread reference information from the object that spawned it?
If anybody out there on the great net can answer even half of one of these questions I will be more than grateful. Thanks for your time, and rock on Java!

Thread t = new Thread(MyRunnableDerivedClass);
t.start();I hope it is understood that MyRunnableDerivedClass is actually an object of the MyRunnableDerivedClass. sorry for the confusion.
so here's a thread that reads from a file using constructors, member variables, other funcs. It's not optimal but shows use of all of the above. I just typed this in so there are probably syntax errors, but you should get the point.
public class ThreadedFileReader implements Runnable
    private File m_File;
    byte[] contents = new byte[0];
    public ThreadedFileReader( File f )
       m_File = f;
    public void run()
        BufferedInputStream bis = null;
        try
            bis = new BufferedInputStream( new FileInputStream( m_File ));
            int avail = bis.available();
            while (avail > 0)
                int oldLen = contents.length();
                contents = expand( contents, avail );
                bis.read( contents, oldLen, avail );
                avail = bis.available();
        catch (Exception e)
        { //do something witty
        finally
            try{ if (bis != null) bis.close(); } catch (Exception e){}
   private byte[] expand( byte[] oldBuf, int addedLen )
      byte[] newBuf = new char[oldBuf.length + addedLen];
      System.arrayCopy( newBuf, 0, oldBuf, 0, oldBuf.length );
      return newBuf;
   public byte[] getContents()
       return contents;
//here's where we use it
File f = new File( "c:\myfile" );
ThreadedFileReader tfr = new ThreadedFileReader( f );
Thread t = new Thread( tfr );
t.start();
t.join();
// At this point the thread has died, but the thread object still exists
byte [] data = tfr.getContents();

OT: Just some general advise on tools

Hi there.
I have Vista Ultimate SP1, CS3.
Seeing that many hardcore developers as well as hobby web
developers
most here, I want some help, please.
I am a hobby/free time web developer which see developing web
sites the
same as someone playing golf for a hobby. I have about 3
sites with ASP
& Access databases and the rest are all mySQL & PHP.
I need to setup my machine to develop & maintain these
sites. What are
the most userfriendly applications I can use for this?
I have used mySQL, PHP and phpMyAdmin to do my few jobs. I
have used IIS
for this.
I was just wondering what else is available for us
non-hardcore
developers who makes 99% use of auto coding.
Thanx for your help.

Hello,
When you say installation problems, do you mean installation problems with the DB on Solaris, or installation problems related to APEX specifically (if so, what were those problems?).
You can certainly use DB links from another instance to integrate with your LIVE system, however if those applications are going to be 'high volume' (where 'high volume' is a very subjective term), I would probably advise that you consider fighting through the problems and installing APEX into the Live machine so that all the transactions etc happen locally (from the LIVE machine perspective), purely to minimize the overhead of the DB Link traffic and to simplify the infrastructure.
However, of course there are reasons/arguments why people might not want to install something like APEX into their live DB server, so it depends on your particular environment which method is most feasible for you.

Thinking of switching to FIOS - Have some general questions:

I am interested in getting FIOS internet and the TV essentials bundle.
In regards to the free 3 month dvr deal - After the 3 months are over do I have to keep the 19.99 DVR or can I drop down to the HDDVR 15.99?
With the TV essentials it lists like 250 channels and up to 14 HD channels. What does "up to" mean? Do I get to pick channels or something?
I have two TV's in my house. If I want the downstairs tv to be able to watch cable do I need to get an additional box?
Can I connect the FIOS internet to a wireless router so my laptop can connect to it?
Thanks. I'm just trying to figure out if it is going to be worth it to switch.

It's the same box. When the 3 months is over you can turn of the Home Media Feature and pay only the 15.99. (when you call many reps on the phone will claim you need to swap boxes but that usually gets sorted out later)
With the TV essentials it lists like 250 channels and up to 14 HD channels. What does "up to" mean? Do I get to pick channels or something?
You don't get to pick anything. If you pay for the higher Extreme HD package you get more of the HD versions of channels. If you don't you only get a small number typically the main networks
I have two TV's in my house. If I want the downstairs tv to be able to watch cable do I need to get an additional box?
Some TVs have a built-in QAM Tuner. If your TV has one it can play some channels. This TV would not get any on-screen guide or Video on Demand (the ones below channel 50 ) without a box.
Some TVs can use a Cablecard. If you order a cablecard (monthly fee) you don't need a box. This TV would not get any on-screen guide or Video on Demand
Otherwise you need a box. There is a low cost version that is smaller and gives all channels but no guide or Video on demand. They are usually 3.99
Can I connect the FIOS internet to a wireless router so my laptop can connect to it?
Your install with come with a Verizon provided wireless router. Just make sure the router is placed in a location that will allow your laptop to connect.
You also have options to use your own router. You can review the options in the NETWORKING section of this FAQ guide http://www.dslreports.com/faq/verizonfios
Thanks. I'm just trying to figure out if it is going to be worth it to switch.

Clustering some general questions:

1. Can dbIsShared be set to false if clustering is used?
          2. Why does Weblogic not automatically provide failover for entity
          beans? Many other servers including WebSphere and iPlanet provide
          that. In other words I would like to be able to set up a clustered
          environment without having to change any code.

          I'm very familiar with Oracle, and you are correct it will not cause
          blocking. I should have been clearer in my response.

          If you design your application to only work with pessimistic locks in
          the EJB container, then your design is flawed. You are depending on
          container internal behavior for your application to work. It certainly
          won't be portable to other J2EE platforms.
          Depending on serializable behavior for your transactions is fine, and
          that's what setting the transaction's isolation level will do.
          Can you give us some more information on why you require a global
          pessimistic lock in a cluster? I am interested in why this is needed in
          your application.
