          output "Enter the number of Jobs"
          set numJobs to input
          output "Enter the amount of cable laid"
          set amtCable to input
          set tempTotal to (numJob * 100) + (amtCable * 2)
          set runningTotal to runningTotal + tempTotal
          output "In month " + empName + "earned " + tempTotal
     endfor
     output "Employee " + empName + "earned " + running Total
endfor
Cheers in advanced     

First of all don't cross post
http://forum.java.sun.com/thread.jsp?forum=54&thread=215879
second of all, if you have questions or problems we will be more than happy to help you solve the problem, or explain an unsure concept to you, but i think i can safely speak for everyone here, we are not going to do your homework for you.

  • Newby needs simple help: modem and ooma

    I do not currently have a high speed internet and I'm considering my options. It appears I may choose a cable provider (I don't have cable tv) and use the cable high speed internet to set up ooma as my phone service, and use an Airport station to set up wireless internet on my Intel Duo 20" iMac and G3 iBook. My main question is..... does the Airport Extreme station function as both a cable modem and a router, or would I need to also buy a cable modem ? Also, if anyone has experience with using ooma for phone service, i want to know if it works well and sets up easy with cable internet and an Airport Extreme. Also, will my 6 year old G3 ibook work with the new Airport Extreme ? Thanks for any help...

    rocket1322, welcome to the discussions!
    "My main question is..... does the Airport Extreme station function as both a cable modem and a router, or would I need to also buy a cable modem"
    The AirPort Extreme does not have a modem, so you would need to set up a cable or DSL modem in your network.
    Sorry, I know nothing about the the ooma service, so can't offer any comments about that.

  • Need Simple help: Unable to Connect to Internet

    Our Airport Express broke, which was the home hub for our 3 other computers. We replaced it with an Airport Extreme, followed the installation. However, now we cannot get it (as the base station) to connect to the Internet. It seems set up but opening Firefox, it cannot find the Internet. However, if we plug the wire from the Comcast modem directly into our Ethernet Port, everything works fine. There are a number of tech posts in this forum but they are way above my head in terms of following them, (ie DNS, etc.) Is there any simple solution we can follow? Thanks.

    You've plugged the ethernet cable form the modem to the correct port, (WAN-which is identified by the circle of dots), on the Airport right?
    Anyway if I remember rightly once connected to the modem and powered on, press and hold the reset button on the back of the AE Basestation for about 10 seconds. Then release and wait. A new network should be visible, probably called something along the lines of Apple Network 300962.
    Connect to it and then open Airport Utility. From there set up your network, (change the name, hide the SSID if you like, add encryption etc etc).
    Now when the Basestation restarts I don't think the Mac will connect automatically as you've just altered all the details. So go to System Preferences>Network and choose a new location to set up. Click the advanced tab under the Airport pane and click the + box.
    Add your network and check the Remember any network this computer has joined checkbox.
    Click OK and then apply..............

  • New to mail need simple help

    I am very new to mac and all of its workings...so this may seem ridiculous but...is it possible to have my gmail account open when I click on an email address within a website rather than mail? if so how do i do that? see easy question.
    thanks in advance
    ibook g4   Mac OS X (10.3)  

    Are you accessing your gmail account with the Mail.app?
    If not, you are able to if interested.
    Other than that, you can select your preferred web browser as the default email reader and make the Home page for the preferred web browser the gmail website but this will not automatically open a new gmail message via webmail access for your gmail account.
    To select/change the default email reader, launch Mail and at the menu bar go to Mail > Preferences > General and at Default Email Reader, select the radio button to the right and choose Select from the pop-up window. A Finder window will appear to choose your preferred web browser.
    Edit - Niel provided info on the Gmail Notifier which is news to me.
    Thanks Niel.

  • Need Flash Help - configuring AIrtight Simple Viewer Pro

    I need some help configuring the Airtight Interactive simple viewer pro, which requires flash. I am a complete beginner with flash, and I am reluctant to undertake the learning curve, though I am very tech saavy.
    My ideal would be to locate someone who could do this FOR me, though resources are very limited for this project. Any suggestions of where I might connect with someone interested in doing this?
    Alternately, I could undertake it myself, with someone qualified to coach me rather thouroughly through the whole process. That could be offline, or here where others could benefit from the thread. If someone offers this, I will post the precise details of what I need. The project is medium challenging, not extremely complex, but more than very basic.
    Many Thanks.

    Hi:
    When you create the simpleviewer slideshow with iPhoto's plugin there should be a folder created on your HD that contains the items seen in the screenshot below:
    The folder was named simpleviewer because that's what I named it during the export from iPhoto. That's the same folder as I refer to as "Slideshow folder". It can be whatever you name it when exporting from iPhoto. Upload that folder to your iDisk/Web/Sites folder as shown below:
    In the iFrame code use the following URL to the index.html file inside the simpleviewer folder:
    http://web.me.com/YourMMe_AccountName/simplerviewer/index.html
    That should do it.

  • Need your help on performance issue please

    Hello everyone!
    I need your help to understand an effect I notice with a Thread class I built. I currently work on enhancement of my application Playlist Editor (see http://www.lightdev.com/page74.htm) and a new release will be available soon.
    Among other extensions the new release will have a title filter function which is based on audio data that is recursively read from ID3 tags of files found in a given root directory. The data collection is done by a CollectionThread class which reads into a data model class AudioDataModel and the entire process works fine, no problem with that.
    However, when my application is started for the first time the CollectionThread runs approximately 3 minutes to collect data from approximately 4300 audio files on an Intel Pentium M 1,4 GHz, 512 MB RAM, Windows XP SP2. When the application is shut down and started again, it takes only a few seconds to do the same task for all subsequent launches.
    I already tried to start the application with java option -Xms40m to increase initial heap size. This increases performance in general but the effect is still the same, i.e. first run lasts significantly longer than subsequent runs.
    I also tried to build a pool mechanism which creates many empty objects in the data model and then releases them to contain the actual data at is being read in but this did not lead to better performance.
    It must have to do with how Java (or Windows?) allocates and caches memory. I wonder whether there is a way to pre-allocate memory or if there are any other ideas to improve performance so that the process always only takes seconds instead of minutes?
    I attach the key classes to this message. Any help or ideas is much appreciated!
    Thanks a lot a best regards
    Ulrich
    PS: You can use the news subscription service at
    http://www.lightdev.com/dynTemplate.php4?id=80&dynPage=subscribe.php4 to be informed when the new release of Playlist Editor is available.
    All classes posted here do not need debugging, they already have proven to run error free. The classes are only posted for information for the interested reader - no need to go through all the stuff in detail - only if it interests you.
    My application calls class CollectionThread wich is a subclass of InfoThread. CollectionThread recursively goes through a directory and file structure and stores found ID3 tag information in instances of class ID3v11Tag which in turn gets stored in one instance of class AudioDataModel. All classes are shown below.
    This is the mentioned CollectionThread

    Hi Franck,
    thank you, mate. I did what you suggested (changed class attached) but that did not change the mentioned behaviour.
    The first run is approximately 75 seconds with Java option -Xms40m and approx. double without, the second run and all subsequent runs are only 2-3 seconds each (!!!) even when terminating and re-starting the application between thread runs.
    I'm pretty clueless about that, any more help on this anyone?
    Thanks a lot and best regards
    Ulrich
    PS: BTW, I forgot to post the class that is filled with data by class CollectionThread, so here it is

  • Anybody who can help me? I really need your help

    I've tried to execute J2ee tutorial examples.
    I don't know why this sample didn't execute...I've already finished to set up J2EE and enviornment variables.
    I was trying this part from j2ee tutorial titled as "Packing Web modules".
    Whenever I type "asant create-war" to make web modules in command window. I always got error.
    Packaging Web Modules(From J2ee tutorial for your information)
    A web module must be packaged into a WAR in certain deployment scenarios and whenever you want to distribute the web module. You package a web module into a WAR using the Application Server deploytool utility, by executing the jar command in a directory laid out in the format of a web module, or by using the asant utility. This tutorial allows you to use use either the first or the third approach. To build the hello1 application, follow these steps:
    In a terminal window, go to <INSTALL>/j2eetutorial14/examples/web/hello1/.
    Run asant build. This target will spawn any necessary compilations and will copy files to the <INSTALL>/j2eetutorial14/examples/web/hello1/build/ directory.
    To package the application into a WAR named hello1.war using asant, use the following command:
    asant create-war
    This command uses web.xml and sun-web.xml files in the <INSTALL>/j2eetutorial14/examples/web/hello1 directory.
    To learn how to configure this web application, package the application using deploytool by following these steps:
    Start deploytool.
    Create a web application called hello1 by running the New Web Component wizard. Select FileNewWeb Component.
    In the New Web Component wizard:
    Select the Create New Stand-Alone WAR Module radio button.
    In the WAR File field, enter <INSTALL>/j2eetutorial14/examples/web/hello1/hello1.war. The WAR Display Name field will show hello1.
    In the Context Root field, enter /hello1.
    Click Edit Contents to add the content files.
    In the Edit Contents dialog box, navigate to <INSTALL>/j2eetutorial14/examples/web/hello1/build/. Select duke.waving.gif, index.jsp, and response.jsp and click Add. Click OK.
    Click Next.
    Select the No Component radio button and click Next.
    Click Finish.
    Select FileSave.
    A sample hello1.war is provided in <INSTALL>/j2eetutorial14/examples/web/provided-wars/. To open this WAR with deploytool, follow these steps:
    Select FileOpen.
    Navigate to the provided-wars directory.
    Select the WAR.
    Click Open Module.
    I guess this step is for checking my system about setup information. I not sure how to change it.

    ok,
    First of all make sure your tutorial folder is installed from the root:
    C:\javaeetutorial5
    or
    D:\javaeetutorial5
    it makes things so simple.
    Secondly:
    set your jee tutorial home
    JAVAEE.TUTORIAL.HOME =
    C:/javaeetutorial5
    Thirdly: check in:
    C:\javaeetutorial5\examples\bp-project
    make a copy of the build.properties.sample save it as build.propropties, as a property file,
    edit the properties file as in:
    build.properties
    As follows:
    # uncomment the property javaee.home, and add the path
    # to your GlassFish Java EE 5 SDK installation
    javaee.home=c:/Sun/SDK
    javaee.tutorial.home=c:/javaeetutorial5
    # Uncomment the property j2ee.server.username,
    # and replace the administrator username of the app-server
    javaee.server.username=admin
    # Uncomment the property j2ee.server.passwordfile,
    # and replace the following line to point to a file that
    # contains the admin password for your app-server.
    # The file should contain the password in the following line:
    AS_ADMIN_PASSWORD=admin1234and so fourth. Some of the settings as the application server name is all done for you
    and then test it again.
    Take care of editing the property file. It can give you headache.
    Note also that this is for application server 9.1 - JEE5.

  • Need some help with a remove function

    Design and code a program that will maintain a list of product names. Use a String type to represent the product name and an array of strings to implement the list. Your program must implement the following methods:
    Add a product to the list
    Remove a product from the list
    Display then entire list
    Find out if a particular product is on the list.
    You need to create a command command loop with a menu() function. The program must continue asking for input until the user stops.
    This is the assignment and this is what I have so far. I need some help writing the remove function.

    I need help removing a product from the arrayYes. So what's your problem?
    "Doctor, I need help."
    "What's wrong?"
    "I need help!"
    Great.
    By the way, you can't remove anything from an array. You'll have to copy the remaining stuff into a new one, or maybe maintain a list of "empty" slots. Or null the slots and handle that. The first way will be the easiest though.

  • Slow Loading On iWeb Pages - Really in Need of Help! (Thanks!!) :o)

    Hi Everyone!
    I have been a lurker here, learning from reading other's posts. I am in serious need of help, as I have been struggling with this issue for over a week and I can't move forward to other things until I get it resolved...
    Here's what's up: I am creating a single-page website as a landing page for a product I offer. (These are very common now in product marketing). The page is here: http://www.howtogetamazingrelationships.com.
    The page that is there is about the 4th iteration of the page in the quest for a faster-loading page. Everytime I test it - no matter what I do - it ends up being about a 24 second load time. Here's a sample test for review: http://tools.pingdom.com/?url=howtogetamazingrelationships.com&treeview=0&column =objectID&order=1&type=0&save=true
    Here are the things I have done to try to speed this baby up:
    1. Took my youtube video off auto-play.
    2. Optimized the site using Web Site Maestro. 27% decrease in size; no load time difference.
    3. Took out shapes and graphics.
    4. Rebuilt the site on a blank template - now it is actually a little worse!
    5. Took out the website.js file - totally messed things up.
    6. Eliminated the navigation.
    Nothing is even showing the least bit of difference in speed...and it is driving me crazy.
    Here's the thing - I have also contacted Web Site Maestro's support for help, and they said that the problem was the size of the site and the length of the page. But here's the thing - I checked the load speed of a page that is about double my page size and length, and it loads in like 4 seconds: http://tools.pingdom.com/?url=http://www.wealthbeyondreason.com/page2.php&treevi ew=0&column=objectID&order=1&type=0&save=true
    Anyone have help/advice for me? I am so frustrated with this, as the iWeb is crazy-easy to build, but I can't have a simple one-page product page load that slow. No one is going to stay around for 24 seconds!
    I just am at the end up my rope and don't know anything else to do. I really don't want to rebuild the site again and still not see results, so any help would be hugely appreciated.
    Thanks so much in advance, and I hope you are all having a beautiful day -
    :o) Tara

    Okay, more info -
    I checked my site on a different web analyzer, and it does seem to be loading quickly - 15.66 seconds for a 56 k, but only 3.6 for T1. So that is good -
    One thing I noticed in the recommendations is that there are 6 scripts that are running, that can slow things down. I don't really know how to change that (I am pretty web-savvy, but far from a developer) Here's what they recommended on the page -
    Analysis and Recommendations from webanalyzer.com:
    TOTAL_OBJECTS - Caution. You have 18 total objects on this page. From 12 to 20 objects per page, the latency due to object overhead makes up from 75% to 80% of the delay of the average web page. See Figure II-3: Relative distribution of latency components showing that object overhead dominates web page latency in Website Optimization Secrets for more details. Consider reducing, eliminating, and combining external objects (graphics, CSS, JavaScript, iFrames and XHTML) to reduce the total number of objects, and thus separate HTTP requests. Consider using CSS sprites to help consolidate decorative images.
    TOTAL_IMAGES - Caution. You have a moderate amount of images on this page (10 ). Consider using fewer images on the site or try reusing the same image in multiple pages to take advantage of caching. Using CSS techniques such as colored backgrounds, borders, or spacing instead of graphic techniques can help reduce HTTP requests.
    TOTAL_SCRIPT - Warning! The total number of external script files on this page is 6 , consider reducing this to a more reasonable number. Combine, refactor, and minify to optimize your JavaScript files. Ideally you should have one (or even embed scripts for high-traffic pages) on your pages. Consider suturing JavaScript files together at the server to minimize HTTP requests. Placing external JavaScript files at the bottom of your BODY, and CSS files in the HEAD enables progressive display in XHTML web pages.
    HTML_SIZE - Caution. The total size of this HTML file is 60492 bytes, which is above 50K but below 100K. With 50K of images and multimedia this means that your page will load in about 20 seconds. Consider optimizing your HTML and eliminating unnecessary features. To give your users feedback, consider layering your page or using positioning to display useful content within the first two seconds.

  • Need serious help with my Zen Microphoto

    My Zen Microphoto controls are messed up. evrytime i try to use the vertical pad it actually forwards me to the next song. When i press back to return to the previous menu, instead of doing that it played music that i did not even select?
    I REALLY need some help here!!! Its a new Zen Microphoto bought only for a month....

    What did you do to control the senstivity of the touchpad. Do you set it to low or med or high I tried all, it is very upsetting not to be able to master something as simple as this. I love the player I just got it yesterday the sound is beautifull although I accidently had it turn to high when it started to play.

  • We have a set of oracle clients running on T5220 zones that need some help

    Greetings all -
    We have a set of oracle clients running on T5220 zones that need some help.
    If, for example, I execute the query "select (all) from dba_objects", trace output reports 90% of the elapsed time spent under "SQLNet message from client".
    Here are OS details for the clients: Solaris 10 5/08 s10s_u5wos_10 SPARC
    Running "uname -a" from the client gives:
    (SunOS bmc-ste-app 5.10 Generic_127127-11 sun4v sparc SUNW,SPARC-Enterprise-T5220)
    Here are OS details for the dataserver: Enterprise Linux Enterprise Linux Server release 5.2
    Running "uname -a" from the dataserver gives:
    (2.6.18-92.1.6.0.2.el5 #1 SMP Thu Jun 26 17:44:55 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux)
    The RDBMS is 10.2.0.4
    Again, please note, there is no application in the picture here. We are just running a simple catalog query (select * from dba_objects) from sqlplus. Why the wait on something like this? The wait also occurs when a different query is used (select (all) from SYS.COL$ where rownum < 50000). And it doesn't matter if I used the full client or the instant client. I still get the same high-wait.
    We had thought - maybe this is a network thing - so we put a test client on the same subnet as the dataserver. This helped - but not enough. The wait is still way too high even with firewalls taken out of the equation.
    We've also looked at arraysize, SDU, kernel settings. And we've spent time going over tkprof, truss and sqlnet-tracing.
    Has anyone ever had to solve this HIGH WAIT ON CLIENT issue? Is there a work around or some tweak I'm missing.
    Is anyone configured like we are (linux dataserver, solaris clients)? If so - did you see anything like this?

    Hello,
    We have the exact same issue. Did you ever solve this issue? We have a t5220 and have just upgraded our 11.5.10.2 11i system on it from 9.2.0.8 32-bit sparc to 11.2.0.1 64-bit sparc. Things should be faster but arent, and our consultant has tracked it down to high wait times when the apps tier using forms connects to the database tier on the same box. So even though the t5220 is both server and client, there is something about the client sql connection.through TNS that his having trouble. Thanks for any information. We've also created an S/R with Oracle.
    Note: I am well aware of the other issues with the CMT server series but this particular issue seems independent of the regular / known issues and remains a mystery to us. Other known issues with the CMT servers for SPARC:

    that is the standard way jaxb generates the model classes. i believe there is some sort of experimental "use simple mappings" switch (probably a vendor extension) which makes the xml files cleaner (similar to your desired implementation), but i don't have much experience with it.
