A few questions needed to finalize a program...

Alright, me and 2 friends have basically written our own sections of the program, and since we're still learning java, don't really know how to bring the three of them together. The program consists of 2 applets (Transposer and History) and an application (chord builder). We've already got the code for each section complete, but it's been pretty difficult to try to link them.
1) I've read up that an .exe of the application would be far too large for my space on the school network, so is there any other way I can cause the application to open in a console when a button in the Transposer applet is pressed?
We have the staff class being loaded into the tranposer applet, but when we try to have the staff class access the array of note values (pitch, octave, duration, etc.) the values all become null. I have tried using both an object returning method within the Transposer class, which didn't work, as well as using arraycopy. Both resulted in NullPointerExceptions when accessing the array.
2) How do I pass the values of the array of notes (object array) from the Transposer class to the Staff class?
Any help would be great.

To paulcw:
Alright, sorry. I guess I should've elaborated a bit more. We're just beginning with Java and are pretty much working without a net here, since the teacher has her hands full with the other people. The applet could probably be used through a web browser, i think... but we're just using it via the applet opened by JCreator's compiler. Pretty primitive, I'm sure, but it gets the job done.
The chord builder could likely be rewritten as an applet, but from what I understand from my friend it would be pretty tedious.
Also, what do you mean by method invocation? Never heard the term before.
The users will be entering the pitch, octave, duration and accidental values through radio buttons, and then once the create note button is pressed, the staff repaints with the new note in place. There are pull-down menus used in order to choose different keys for transposition, as well as a pull-down menu for instrument history.
To sscotties:
We haven't been really been taught swing to be honest, we've learned what we could through the forums and tutorials, but currently we're only using a JPanel for the Staff class. For someone who knows little about swing, would it be possible to rewrite the entire program within 2 wks (deadline)?

    something diffrent, and what will i need more i mean
    jsp, servlets?Yes, learn JDBC. And servlets and JSPs. That's quite a lot.
    Sorry for such a question but i'm just beginner in
    j2ee and i hope you will help me :)I don't know how this helps you. It seems to go without saying: If you want to write Java EE applications, you should know Java EE well.

  • Considering a Mac Pro - Few Question

    I am disappointed with my Intel iMac due to lack of USB ports (hubs don't work with some of my usb hardware) and the ridiculous audio/optical combo port. So I think I may go Mac Pro when Leopard is released. A few questions need to be answered if you would be so kind. A few caveats first...
    A) Mac Pros are expensive for me, so I need to save money where I am able.
    B) The Mac Pro will double as a media player for my Home Theater system. I have a connection for DVI and Toslink
    OK, now the questions...
    1. Does the Mac Pro come with the trays for the extra hard drives? I would like to purchase more drives separately. Can I do this, and what type of drives are used, SATA?
    2. RAM from Apple is expensive. Is there a less costly alternative? It must be a dependable brand. Please include part number if available. Thanks!
    3. Will reduction from 2.66 to 2.0 ghz make that much difference? I like grinding MP2 videos to H.264. Really, will it be worth the additional $264?
    4. I can use both DVI or HDMI to go to my Home Theater system. Currently, starting the Home Theater changes the resolution on my iMac. I would like to avoid this. Should I get another NVIDIA GeForce 7300 GT, or will the dual port on the one card be able to be set to a different resolution output? I would like to be able to still work on my Mac while the kids are watching something in the theater.
    5. As for audio, will I be able to run headphones, external speakers and optical out all at the same time? I am assuming yes, but just want to make sure.
    6. I am also assuming the Mac Pros are quiet. Noise is one of my biggest enemies since I do quite a bit of audio work. I have not heard a single complaint regarding noise from Mac Pros. Are they that quiet?
    Thanks in advance everyone!

    4. I can use both DVI or HDMI to go to my Home
    Theater system. Currently, starting the Home Theater
    changes the resolution on my iMac.
    You should be able to run different resolutions on the built-in display and external display if Mirroring is turned off in "Displays" System Preference.
    I would like to
    avoid this. Should I get another NVIDIA GeForce 7300
    GT, or will the dual port on the one card be able to
    be set to a different resolution output? I would like
    to be able to still work on my Mac while the kids are
    watching something in the theater.
    The two DVI ports can run at different resolutions.
    5. As for audio, will I be able to run headphones,
    external speakers and optical out all at the same
    time? I am assuming yes, but just want to make sure.
    The optical out uses the same socket al the audio out, so you can't use both at once. You could add an iMic <http://www.griffintechnology.com/products/imic/> to get an additional audio output. There are also other PCI-Express, FireWire, or USB audio interfaces available.
    You can also use an AirPort Express for audio output. It is designed for iTunes, but Airfoil <http://www.rogueamoeba.com/airfoil/mac/> will send any audio to it.
    You may need Audio Hijack Pro <http://rogueamoeba.com/audiohijackpro/> for different applications to send audio to different, or multiple, outputs simultaneously.
    You may also want to consider the Apple TV <http://www.apple.com/appletv/> for audio and video connections to your home theater.

  • Few questions on Report programming

    Hi guys,
    I have few questions on report programming.
    1. What is the purpose of the statement REPORT zxxx. Even if i gave a name other than my report name i don't find any difference in syntax check/Functionality.
    2. What is the purpose of list headings in report program? This option will come along with the text elements and selection texts.
    3. What is the purpose of logical data base. Even if it is efficient why don't we use it frequently in our reports? Is there any limitations?
    All usefull answers will be rewarded as usuall:-)
    Thanks,
    Vinod.

    1. As u told that you dint get any syntax errors even after changing the Report Name,there are chances of getting Runtime errors.
    2. The usage of List Headings is when you create a list in a program, you can also create your own list and column headings.
    Refer this link for further info.
    http://help.sap.com/saphelp_nw70/helpdata/en/e3/960a05eb0711d194d100a0c94260a5/content.htm
    3. The Limitation of LDB  is the usage of GET statements which act similar to SELECT - ENDSELECT And also if you dont choose the proper LDB,a  single LDB may contain data retrieval from so many tables ,that it would make the entire process very slow and it is very hard to find LDBs for other modules than HR.
    Only in HR module the data is organized in such a way thatusing LDBs would be much simpler.
    Reward points if useful.

    If it can't be done by the Mac OS (she hasn't mentioned what she has) then it can be done with Acrobat. She asked about a program to create PDF files. That's pretty much what Acrobat does.
    where is whatI said.
    Being That LiveCycle designer is not availble for Mac. That would be about the only thing to recommend. InDesign Maybe but more pricey.
    The part I've underline refers to Acrobat.  InDesign Maybe but more pricey referes to, Indesign being more expensive than Acrobat.

  • Few Questions (Help Needed)

    Hi,
    I had few questions regarding captivate 4. If anyone can help, I would really appreciate it:
    1) I created an eLearning project and it has some quiz sildes in them. So how do I collect the scores of the users who will go though that eLearning? ( I googled it but in most of the webpages they say just put a tick on report answers and also in the preferences enable reporting for this project) I tried using that but can`t see how to fetch the score for each users.
    2) In the same eLearning I want to get feedback from the users who watch the eLearning. So basically I want a slide in which users can type in their feedback and then when they hit the submit button that feedback should be sent to a specific email. ( For this I tried using text box entry but all the text we enter in that comes in one line, we can`t press enter to change lines, also in the button I assign it to send an email to my lotus notes email id, but when I preview the project and click the button, it opens my lotus notes and it does not fetches what I have entered in the text box)

    Hi there
    You need to be investigating another piece of software that works in conjunction with applications like Adobe Captivate. Generically it is known as a LMS (Learning Management System).
    There are tons of them out there. You might begin by looking at the link below:

  • Need help with Java, have a few questions about my Applet

    Purpose of the program: To create a mortgage calculator that will allow the user to input the loan principal then select 1 of 3 choices from a combo-box (7 years @ 5.35%, 15 years @ 5.50%, 30 years @ 5.75%).
    Problem: My program was working properly (so I thought). I can get the program to properly compile and run through TextPad. However, I noticed that when the user clicks the calculate more than once (with the same input), it slightly alters the output calculations. So that is my first question, Why is it doing that?  How can I get it only calculate that information once unless the user changes it etc?
    My next question is regarding my exit button. I was told by my instructor (who has already stated he won't help any of us) that my exit button does not work for an applet and only for an application. So, how can I create an exit button that will work with an applet? I thought I did it right but I can't find any resources online for this.
    Next question, why isn't my program properly validating invalid input? My program should only allow numeric input and nothing more.
    And last question, when invalid input is entered and the user clicks calculate, why isn't my JOptionPane window for error messages not displaying?
    I know my code is a little long so I have to post this in two messages. Please don't criticize me for what I am doing, that is why I am learning and have come to this forum for help. Thanks

  • A few questions before I buy a new iMac/Mac mini and sign up for Creative Cloud.

    Hello Everyone,
    I am looking to purchase a new Apple computer and sign up for Creative Cloud within the next week and I have a few questions that should be answered before I proceed.
    My wife and I own a business and we will be using the CS6 apps to create brochures, Constant Contact mailings, product package inserts, edit product photography for print and web use, and short HD how-to videos. We are not graphics professionals or power users and wont be doing anything too complicated.
    Any help and answers will be greatly appreciated.
    I will start with the hardware questions first:
    I am trying to decide between the iMac and the Mac mini.
    The iMac is a 2.7Ghz Quad-core Intel core i5 and comes with 4GB of memory that is expandable to 16GB, which I will do for sure. It comes with a Radeon HD 6770M graphics card with 512MB of GDDR5 memory(not upgradable), and a 1TB HDD that runs at 7200RPM. This unit meets the specs required.
    The 2.5Ghz Mac Mini comes with 4GB of memory that is expandable to 8GB, I will also do this. It has a Radeon HD 6630M graphics card with 256MB of GDDR5 memory(not upgradable), and a 500GB HDD that runs at 5400RPM. This unit meets all the spec(I think) except for the speed of the HDD.
    Question: Will the mini run the software without too much of an issue considering the speed of the HDD?
    Question: Will the iMac run the software significantly better to justify the price difference?
    I already have 1 mini(purchased 4 months ago, with the same specs listed above) and will be purchasing a second computer for my wifes desk. If the mini will run CS6 fine, that is great and we can save a few bucks. If my mini will not run CS6 well, I will get the iMac for her desk as she will be doing the bulk of the work in that regard anyway.
    Now a couple of software questions.
    After reading hundreds of reviews and forum posts over the last few days I have seen many people having this or that issue. It seems to me that most of the issues are because of upgrades from Lion to Mountian Lion after installing CS6 first or trying to open CS3,4,5 files in CS6.
    If you want to know what issues have me concerned take a look at just this one forum:
    http://blogs.adobe.com/jnack/2012/07/adobe-cs-apps-mountain-lion-no-known-issues.html
    Similar issues are discussed in the Apple forums as well as many other places around the web.
    I am not a computer professional but I know enough to maintain my systems and keep them running smoothly.
    We do not have any Adobe software installed on my mini and will not be opening any files from previous versions of Adobe product in the new CS6 software. These will be a clean installs on pristine systems running fully updated Mountian Lion OS's on both machines and creating new files from scratch.
    Question: Should I be expecting any issues like the ones I have read in the forums and blogs or are these just the normal things that happen when upgrading to new software with multiple hardware configurations?
    My feeling is that we will not be having too much of a problem due to the clean installs and no files from previous versions.
    Next up, the Creative Cloud(CC) FAQ states that you can install on 2 machines but can't open stuff at the same time.
    Question: Does this mean we can't be using any CS6 apps at the same time or just not using the same app at the same time?
    Example: PS and PS on both machines at same time = No, PS on one and Dreamweaver on the other at the same time=Yes?
    The CC FAQ page says Adobe will add Lightroom 4 later in 2012 while the main CC page lists it as available now.
    Question: Which is true?
    My mini is registered to me, with my name, iTunes account, Apple ID etc.
    Question: Do I need to do the initial set-up of the new machine with all my information to ensure the CS6 suite works on both machines? Do the computers need to be registered(as far as Apple configuration is concerned) to same person for them to work on one CC account or can I install CS6 on any 2 machines regardless of how they were initially set-up?
    This may seem like a silly question but I want to avoid any problems before they happen.
    Well, those are all of my questions at the moment. To anyone who made it this far in my looooong post, Thank You so much for your time. I appreciate your expertise and knowledge and hope that you can help me make this decision.
    Cheers,
    Alex Bogdan

    Alex,
    I'll try and answer your questions as best I can.
    Qn 1 Which Mac.
    Ans:- As I understand it both units will run Adobe CS6.
              Which one really depends on what you wand from CS6. If you are looking for high end demand and performance, then I would go for the IMac
              Your Specs for the Imac are right. However if you buy your IMac straight from Apple there are even higher specs.
              You can get:-
                                  3.4 GHz i7 processor rather than the i5
                                   2GB video card as opposed to a 1Gb video card.
                                   Of course such a model will cost you more.
              In the end it is needs compared with money to spend. That is only a decision you cam make.
    Q2:- Will the higher cost for the Imac justify copst.
    Ans:- Again it depends on what demands you intend to make on the hardware and software.
              But I note you have a business and if that businees expects to high demand and high speedy performance then I suspect the Imac would be more able to provide your needs.
              Again only you will know the answer to that.
    Q3:- Questions about CS6 reliability
    Ans:- I have been with Adobe for way over 10 years.
             Speaking, only for myself, it is the most reliable software on the market.
              It is true that if you look down this form, like any other and I am thinking about the Apple discussions forum, you will find numerous instances of problems.
              Again this is only my opinion, but although all these problems are real for the individuals:-
              First it is not clear why they have the problem e.g. what have they done or not done.
              Second, they are in the minority of the total users using the hardware / software.
              The only problem I am aware of with CS6 is Acrobat X. I understand it has been sorted Adobe, however it cost me so much work I have removed it from my system and reverted to Acrobat 9
              So what I am saying is that there are only two comapnies I rely 100% on: They are Adobe and Apple.
             So if you are happy with my opinion I would not worry about Adobe CS6
    Qn 4:- CS6 0n 2 machines.
    Ans:- Yes you will not be able to run the same program similtaneosly.
               I believe, if it is important that you do run the same program together, that you can acquire a further licience from Adobe to do that.
               You would need to contact Adobe about that.
    Qn 5:- Lightroom 4
    Ans:- Lightroom is now available as part of Creative Cloud.
    Qn 6:- Set up for individual machines
    Ans:- I do not believe you do. Once you have set up your Creative Cloud account you go to the apps site and download the apps for each machine.
              Each machine downloads the apps and your machine and the apps are registered by Adobe.
             Here is something that you may want to know:-
              Because I was so unhappy loosing all the Acrobat data with Acrobat X I ended up deleting Acrobat X
              However as far as Creative Cloud is concered Acrobat X is still on my machine.
              It is not a problem for me because I am happy with Acrobat 9, it fullfils my needs and has not crashed and lost me all my bookmarks.
              However here is the point:-
              Adobe, when there was a problem with Acrobat X requested that no-one deletes the application.
             Though I do not know for certain I believe registration of the apps you have with Creative Cloud are registered with Creative Cloud in their database. Therefore were you to delete an app, it will still be registered with Creative Cloud and you will not be able to download a further copy even though the app is no longer on your    machine.
              Therefore it maybe not a good idea to delete an app when you no longer have a use for it. If you want it back I suspect you will have to contact Adobe Support
    Personal Comment:-
              It is true many unfortunately have had all sorts of problems, including me with Acrobat X.
              That said, Creative Cloud in my view has been a major advance in how Adobe delivers software. I have no regrets with signing up to Creative Cloud and I expect to remain with it.
    Hope all of that goes some way to answering your questions.

  • Few Questions on the Creative Cloud

    I have read that the Creative Cloud Connection will be released within the next few weeks which is great. I have a few questions about file uploading and the Creative Cloud Connection program.
    I have a folder which I will upload. The contents of that folder will be updated periodically locally. I want to the files in that folder to stay up to date between my desktop and laptop. Will the Creative Cloud Connection program be able to do that?
    If a file is changed that is already in the cloud will the program recognize the change and keep the cloud up-to-date?
    I guess a little more information about exactly what the Creative Cloud Connection program will do would be nice.
    On the topic of storage will I be able to upgrade from the standard 20 gb of storage that is available when/if needed? And how much will that be?
    One other question:
    When will Lightroom 4 be available via CC and why is it not available since it has been released?

    Creative Cloud Connection will keep files between your desktop and the website in sync. You will be able to add, edit and delete files from either end and see the changes reflected in both.
    To see the the Creative Cloud Connection in action you can watch this video from Adobe evangelist Paul Trani http://tv.adobe.com/watch/adobe-creative-suite-6-creative-cloud-launch-week/adobe-creative -cloud-tour-/.
    There will be a way to get more than 20 GB of storage. The Adobe Creative Cloud FAQ http://www.adobe.com/products/creativecloud/faq.html has a question and answer about this near the bottom:
    Can I buy additional Creative Cloud storage?
    Additional storage will be available for purchase later in 2012. If you have reached your storage limit, contact Adobe Customer Service.
    Lightroom 4 will be available in a few weeks. Jeff Veen has also tweeted this https://twitter.com/#!/veen/status/200810541550288896. More from Jeff on what is coming to the Adobe Creative Cloud here in his Adobe blog http://blogs.adobe.com/creativecloud/coming-soon-to-creative-cloud/.

  • Thinking of getting an iPad but have a few questions

    After using the iPhone 4 (3GS previously) and really liking the OS on it, I am thinking of purchasing an iPad to make reading ebooks easier, also, having the iPad would be more convenient for me to quickly go on the net in my home (or other wifi area, but mostly home use) to seek information and also check, send emails, rather than having to switch the computer on all the time and then having to wait for it to load up and also with the iPad, the larger screen would make email, internet use and ebook use more pleasurable due to the iPad's larger screen when compared to using my iPhone.
    I have a few questions that I would like to ask to iPad users, who could perhaps answer them for me?
    In my household we have 2 iTunes libraries, one for my iPhone and one for my girlfriend's iPod. I created a separate iTunes library for each of the devices so that each one would have a totally separate library and therefore the possibility of having one overwriting the others library would be impossible.
    Now ideally I would be wanting to create a separate iTunes library for the iPad, but I would want to add the music and apps, email accounts, bookmarks that I have on my iPhone and add them onto my iPad. Would this possible?
    Also. I believe some apps have specific versions for either iPhone or iPad, so would the iPhone versions of the apps run on the iPad, or would I need to download the iPad versions of those particular apps?
    Also. I have a number of DVD's that I have converted and then dragged and dropped the video off of them into iTunes. If I am correct, would I need to reconvert those videos/DVD's again, as the video size (screen size) would be for the iPhone and therefore a smaller screen, which would not look very good on the iPad's much larger screen. If this is the case, can anyone recommend a good video converter for converting video for the iPad and what settings need to be used for the iPad?
    I also would be wanting to have a number of photos on the iPad. To get them onto the iPad, is it just a simply matter of selecting the pictures I have on my computer that I want added to my iPad, and then just dragging and dropping them into iTunes, then connecting and syncing the iPad to get them added on to the iPad, or is there an easier method?
    Thanks in advance

    Funny you should mention Macs, but I'm thinking of my next computer been an iMac, and using the Parallel Desktop software so that I can have functionality of been able to switch to Windows when needed to run the programs that are not Mac compatibly. I'm swaying towards Mac has I have heard their OS is more reliable and secure compared to Windows, and the need to have anti virus and anti spyware programs on a Mac is not really needed, but I figure if I can run Windows on a Mac then I have the best of both worlds, anyhow back on to topic
    I do indeed take backups of the various libraries and related data for them.
    I have used the Dropbox app and was impressed, but I did prefer an app called iFiles which allows me to carry various files/files types around with me on my iPhone, such as PDF files, Word doc files etc.
    The reason I use the method of having a separate iTunes library for each device we use on the computer, (my iPhone, girlfriend's iPod, and soon maybe an iPad) is because I accidentally replaced the music I had on an iPod I had at the time with my girlfriend's music. So from then on, that's why I have created a separate library for each Apple device, and so far I have never accidentally messed up another devices contents.
    Thanks for the help its much appreciated.

  • Thinking of moving to iMac from PC, got a few questions

    I'm thinking of moving to an iMac for my next computer, probably in the next 6 months or so, but I have a few questions I wondered if you might be able to help me with.
    I'm planning on getting Parrallels Desktop and installing Windows. Now I know Time Machine takes backups every hour. But I was wondering if it will also backup not only the Mac side but the Windows side too.
    For example, if I install a program on the Mac side, edit a file, delete a file etc, Time Machine will backup the changes on its next backup. If I done the same while running Windows, i.e install a program on the Windows side, edit a file, delete a file etc, does Time Machine backup these changes for the Windows side too.
    Presently for my backing up purposes. I have a hard drive caddie which has a esata connection as well as a USB connection. I have a 3.5 inch 1 TB sata drive that slides in and out of my caddie by way of (for want of a better word) a cradle. I'm planning on getting a 3.5 inch 2 TB sata drive and an additional cradle so that I can have a large collection of backups.
    Now with the hard drive caddie I've mentioned above, to use it on an iMac, I would only be able to connect it via USB. My fear with this is that it will be a lot slower at taking backups to what I am currently used to seeing when I have it connected to my PC via esata.
    I thought about this and noticed the LaCie eSATA Hub Thunderbolt Series on the Apple website http://store.apple.com/uk/product/H8875ZM/A/lacie-esata-hub-thunderbolt-series?f node=5f&fs=m.tsConnections%3Desata
    From what I can gather, it would allow me to connect my current esata caddie up to it and it would increase the performance of it to Thunderbolt performance and also would allow me to make use of my current hard drive in the process. I was wondering if anyone has used this hub and if so, is the performance significantly improved. I thought that Thunderbolt would be a good and extremely fast way of taking backups. I will point out that I find that the taking backups every hour with Time Machine, for me would be a bit of an overkill, so I'm planning on just switching Time Machine off when I don't need it to take backups, and then switching it back on when I want it to take a backup. Doing this could result in larger backups than if I had it doing it hourly, so again I thought something that would give me Thunderbolt performance would be good for this scenario.
    Any help and advice would be appreciated.

    By default TimeMachine does not back up your Parallels virtual machine and if you think about it that's a good thing. Since the Virtual Machine is in effect a hard drive, just booting up Windows or launching a program changes the VM file as temporary files are created. My VM is 25GB so not only would TimeMachine be making a copy of the VM every hour that Parallels is running, it would be copying 25GB! Not good.
    There are a number of solutions. On my desktop I use a different program to backup my VM each evening about the time I eat dinner. On my notebook I have a repeating reminder that asks if I've backed up my VM recently. As far files go, my solution is to save all my files to my Mac drive space so that TM backs them up.
    USB is slower than eSATA but for day to day use, USB is fine for TimeMachine. The initial backup will be longer and OS updates will result in longer backups but otherwise....I have a USB drive connected to the computer I'm using right now. On most hourly backups TM is running a couple minutes and it doesn't require much bandwidth or CPU so the only time I really notice it running is I look at the drive light.

  • A few questions from a newbie!

    Hello!
    So, I am VERY new to using Mac productions and I just got my Macbook recently.
    I have a few questions that may seem to have a very simple and obvious answer but like I said, this is all new to me...
    1. Do I have to install a anti-virus/spam program? If so, which one?
    2. Time Machine- this is the program to back up files right? when I try to set it up it doesn't give me any options for a back up disk.
    Anything else that I should defiantly know please let me know!
    Thanks so much!
    Alanna.

    Not unless you want to. I have had Macs for 2 years and never had a problem. This is a good one if you decide to install one. ClamXav
    2. Time Machine- this is the program to back up files right? when I try to set it up it doesn't give me any options for a back up disk.
    You need an external hard drive attached to use with Time Machine. This explains it.

    This is info that will help you get the best life from your battery.
    It is OK to leave your battery hooked to the charger most of the time. The only time I unhook mine from the charger is when I calibrate or for a few minutes to use in another room. Have you calibrated your battery yet? You should calibrate every two months or so to keep the battery fully functioning. If you use your MacBook infrequently, it’s best to re-calibrate the battery at least once a month.
    It is best not to use your battery unless you need to. Some people have hurt their batteries by charging then discharging every time they use the MacBook. This will age a battery very fast and cause you to buy a battery sooner than you should have too. Don't discharge the battery just because you used it. Li-Ion batteries prefer small charges over big ones. Use it and then plug it in as soon as you can. The only time my Battery is ever fully discharged is when I'm doing a calibration.

  • Few questions about customizing jwm

    Hello all,
    Coming from KDE, I found jwm and it runs so much better on this circa 2008 laptop. KDE runs OK but this is a lot faster. I have familiarized myself with .jwmrc and how to make basic changes and I've come across a few questions.
    1.) Is there any way to enable dragging and rearranging the open programs in the taskbar? I'm kind of OCD about the order of my running apps especially since restarting jwm after edits to the config file puts them in a random order.
    2.) I think I see a way to get programs to start maximized and such using Groups but is there a way to start a program with a specific size? Specifically I am referring to nedit - it always starts too small and I size it so be larger but not overlapping my conky.
    3.) Relating to #2, is there any way to get all programs to remember their window's size and position upon restarting? This has been a pet peeve of mine for years and KDE has the ability to remember this but most other Linux DEs and WMs don't.
    4.) I've been using slock to lock the screen but I need to run it manually. Is there any way to get slock to run automatically, ie after say 5 minutes of inactivity? As of now I've been using xscreensaver to power off the monitor - should I just use the "Lock screen" option here? I've been trying to keep this install as minimal as possible - I don't need a screensaver, just ideally to turn off the monitor and lock the screen after some time.

    1) I don't think you can - you can however disable the jwm taskbar and use xfce4-panel or similar.
    2/3) Devilspie
    4) xautolock

  • A few questions about Boot Camp: installation, performance, which Win OS?

    Hello.
    I am planning on getting a windows OS. My main motives for this are because I would like to get some PC only games (I've been eyeing that Fallout 3 Game of the Year Edition that is soon to come out) and because there is a good chance that I will need some PC only programs for my college work. I just had a few questions before I did anything. Note: I am running 10.5.8 now but getting 10.6 soon.
    1. According to wikipedia: "Its functionality relies on BIOS emulation through EFI and a partition table information synchronization mechanism between GPT and MBR combined". The only word I understood of that sentence was "emulation." I know that emulation software significantly reduces performance. Is this true for boot camp? (say i were to get the exact same game for both mac and windows and set them to the exact same performance settings, when playing on windows, would there be more lag than on OS X?)
    2. Which Windows OS should I get? Since I am just going to be using Boot Camp to run games and a few other programs, would XP be the best to get to optimize the application's performance (as opposed to Win 7)?
    3. How complex is installation? I am a decent Mac techie, but this is my first time with boot camp, and I am a Windows noobie.
    4. There seems to be a lot of talk about partitions. What exactly is a partition? I have some theories, but want to know for sure.
