Will Java 8 include a Tool that will allow multiple versions of Java to run together?

We continue to struggle with an absolute need to run multiple versions of JAVA at the same time on the same PC.
Will JAVA 8 include a Tool, add--on, extension, something, that will allow this requirement to be executed?

Given that that's been possible for over a decade, there's no need for such "tools". All you need is knowledge of your operating system.

  • Is there a converter that will allow earlier versions of Audition to open sesx files?

    Is there a converter that will allow earlier versions of Audition to open sesx files?

    SteveG and ryclark have this covered.
    The only thing I would add is that if you really must convert from CS5 to AA3 then use AATranslator to convert to an AA3 xml.
    No fx will be converted but you will get the best possible conversion.
    Again this is only if you must and obviously the earlier in the project (before applying fx) the better.
    FWIW you would only need the $59 version but certainly it is good advice to keep multiple AA versions on your PC

  • Will Keynote '09 version 5.1.1 run on 10.7 Lion?

    Will Keynote '09 version 5.1.1 run on 10.7 Lion?

    I have done hours of work making presentations in Keynote 5.1.1 under OSX 10.6.8 and have been tempted to go up to Lion 10.7 but have read of problems with Keynote. You have suggested upgrading keynote to 5.3  and so I wondered if that would affect the work I have done already. `Thank you.

  • Is there a proven method of source control that would allow multiple authors to work on the same RoboHelp v11 project? Any advice would be appreciated.

    I was wondering which means of source control has proved the easiest to set up and live with for working concurrently on a RoboHelp project. Ideally, we would like to use Subversion, but would also consider Sharepoint, or other recommended solutions. Any experience you could share would be much appreciated.

    You could do a lot worse than look through the discussions over in the Source Control forum. Personally I use SVN although not integrated through the RoboHelp UI. There are others that do though. You'll find there are a selections of users using all sorts of source control apps with RH. Others not mentioned so far include Perforce, Team Foundation Server. It should just be a case of making your choice and then testing it to ensure it meets your needs.

  • A PKGBUILD that allows multiple installed kernels

    Hi All,
    I've had so many people help me with so many things here at Arch, hopefully this will be useful to someone.
    What is it:
    I've got a kernel PKGBUILD file that allows me to build and install as many different kernels as desired, as long as each one has a unique $pkgver-$pkgrel setting.

    cd $startdir/pkg/lib/modules/$pkgver-$pkgrel &&
    (rm -f build; ln -sf /usr/src/linux-$pkgver-$pkgrel build)
    How it works:
    The primary thing I've usually done is wipe out my custom kernel by inadvertantly overwriting the loadable modules in the /lib/modules/$pkgver directory with a pacman -Su.
    The reason for this is that the current arch kernel build does not set the EXTRAVERSION variable in the kernel top level makefile. Therefore all kernels of the same $pkgver use the same /lib/modules/$pkgver/ subdirectory.
    The above PKGBUILD sets EXTRAVERSION to the $pkgrel variable.
    This causes the loadable module tree to be in a /lib/modules/$pkgver-$pkgrel/ directory.
    There are two other places where kernels experience file conflicts:
    /boot/
    /usr/src/
    The /boot/ files: vmlinuz, System.map and kconfig are given unique names by appending the $pkgver-$pkgrel string.
    The /usr/src/linux-$pkgver/ directory is moved to /usr/src/linux-$pkgver-$pkgrel/.
    This allows the loadable kernel, the loadable modules and the stripped source headers to be in a unique place for each different kernel. Therefore multiple kernels can be loaded concurrently and the desired one may be chosen at boot time by grub.
    The only thing a little weird about this, is the $pkgname variable. pacman will only load one version of each $pkgname, so for multiple kernels to be loaded, they each have to have a unique $pkgname. This is accomplished by appending the $pkgver and $pkgrel to the $pkgname. This is fine, except it gives a slightly weird name for the resulting kernel package file. It has the format:
    kernel$pkgver$pkgrel-$pkgver-$pkgrel.pkg.tar.gz
    That is, the $pkgver and $pkgrel appear in the package file name twice. This also shows if one issues:
    pacman -Q | grep kernel -
    Which yields for me:
    kernel2.6.6custom1 2.6.6-custom1
    kernel2.6.61 2.6.6-1
    kernel26 2.6.7-1
    This command could only have shown one package before, now it shows that I currently have installed: a custom 2.6.6 kernel, the stock arch 2.6.6 kernel built with the above PKGBUILD and the current arch kernel26 package.
    I may choose between any of these at boot time with grub. And as an added bonus, the next time I pacman -Su I won't wipe out my custom /lib/modules subdirectory 8-)
    All of this assumes the supply of your own custom config file as in the arch wiki Building the Kernel in ABS instructions.
    Idle thoughts:
    It would sure be nice if something like this could be adopted for the stock arch kernels. Unlike most other packages it is often desirable to have multiple versions of the kernel package installed at once.
    I wonder if it is practical for pacman to allow multiple versions of the same $pkgname to be installed concurrently if the $pkgname-$pkgver-$pkgrel string is unique and the different versions do not have file conflicts?
    The other major package I could see this being applied to is gcc. It would be really cool to load different cross and other configurations of gcc concurently.
    I find one of the most diifficult things needed to get a workstation running is getting all of the correct kernel modules built in. It seems that most PCs today have all the major features built in to the motherboard chipset: graphics controller, sound, usb, ethernet, etc. If it was possible to build a database of custom kernels, one for each major chipset, then one could be chosen by hardware detection at install time. This would provide the benefits of a custom kernel in an autoload fashion.
    Just dreaming...
    Conclusion:
    I'm not sure how this strategy fits in with the bigger pictiure of running pkg repositories, building dependent packages, who knows what else.
    The thing I hope to add next is automatically adding and removing entries into: /boot/grub/menu.lst when the kernel package is installed and removed. The $pkgdesc string is perfect for serving as the title line.
    Hopefully this can be useful to others, it has helped me clean up my multi-kernel mess here.
    Thanks Again for such an awesome distro...
    John E. A.
    p.s Arch Rulz!

    Thank you, I tried to set something up like this in the wiki, but never tested it and it didn't work for some users. You've tested it well?
    If so, you can copy it over to the wiki (edit or overwrite the Kernel compile with ABS wiki entry), or I can.
    Thanks again, its much appreciated.

  • Magic wand tool that will select broken-line shapes?

    I'm an illustrator... working in both digital & real artwork.
    I work mostly in Photoshop CS, but I have been searching for a solution to a digital problem that I can't quite seem to find using either Photoshop or Illustrator.
    What I wish to do is scan a pencil drawing and then create selected shapes in a quick and easy method using a magic wand tool.
    But it needs to be a magic wand tool that will select an area drawn from a series of broken lines. Photoshop will only select shapes that are 100% intact, so I wind up having to spend lots of time searching to repair broken lines before Photoshop selects just that one area.
    I KNOW that such a program exists... because I recall there used to be such a program. It was a free dowloaded program that I got once, way back around 1998. I think it came from Australia... and it was a basic digital paint program of some sort. I can't recall the name.
    It allowed one to quickly click and select an area from within a shape drawn with broken line segments...
    Does anyone know of any program (hopefully for Mac) that allow this sort of selection?
    This would save me hours of frustration. I can't believe Adobe hasn't come up with something like this already.
    Thanks...

    I doubt that I will get to trying the proposed method on that sample image this weekend. I can make a few quick comments, however.
    Like numerous Photoshop tools, the success of Illustrator tools like Live Trace and Live Paint are very image dependent and some experience helps. Here are some comment on the three steps needed.
    First, the Live Trace step must be done well. There are a boat load of parameters for this process. For the subject image my guess would be to start with a preset and the one I would choose would be comic art.
    Secondly, once you make a live paint group you have to have automatic gap detection checked (turned on) and you choice of predefined or custom gap sizes specified. You will then see where the gaps are automatically found and fixed and the gap options dialog box will tell you how many have been found. If you like what you see you can just start painting. Usually, however it is an iterative process of painting some of the areas and then resetting the gap detection and painting again. At any point you can automatically close the paths (but you cannot go back), change the settings to auto detect even larger gaps and try again.
    Third is the manual phase. If lucky you will have none of this. On the subject image, however, I can see that some of this is required. To preserve the artistic content of the original one draws a line in the very big gaps having no stroke or fill (invisible line)and then you use the live paint bucket. While the above sounds like a lot of work, it can go very quickly with many drawings.
    JN
    >That's why I think Adobe ought to work on designing a 'smart magic wand tool'... that could select imperfectly closed shapes.
    The Live Paint tool in Illustrator does this. It automatically detects gaps and lets you paint as if they were not there.

    Minimally you need Snow Leopard or greater:
    Upgrade Paths to Snow Leopard, Lion, and/or Mountain Lion
    You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
    Upgrading to Snow Leopard
    You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard — Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
    After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
         Snow Leopard General Requirements
           1. Mac computer with an Intel processor
           2. 1GB of memory
           3. 5GB of available disk space
           4. DVD drive for installation
           5. Some features require a compatible Internet service provider;
               fees may apply.
           6. Some features require Apple’s iCloud services; fees and
               terms apply.
    Upgrading to Lion
    If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
    You can purchase Lion by contacting Customer Service: Contacting Apple for support and service — this includes international calling numbers. The cost is $19.99 (as it was before) plus tax.  It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.

  • Where is the Url for free Adobe Acrobat X Pro that will allow me to create PDF/X ‑1a requires all fonts to be embedded,

    Is there a free copy of Adobe Acrobat Pro that will allow me to create PDF/x‑1a with all requires all fonts to be embedded. I already have Adobe Acrobat Pro XI.

    The Standard joboptions that are used by default don't embed most so-called system fonts.
    Change your joboptions to High Quality Print and you will get Arial embedded plus much higher quality imagery.
    BTW, PDF/X is great (I'm actually Chair of the PDF/X standards committee), but PDF/X-1a created by using the PDF/X-1a joboptions ruins output by flattening transparency, yielding stitching and other image artifacts that you can see both on screen and print if your document has any transparency (including drop shadows, reflections, and even clipped images). It also forces all content to CMYK. PDF/X-4 is a better choice.
    What are you creating the PDF file from? Microsoft Office documents? Adobe layout programs such as InDesign?
    Let us know and we can give you a more focused recommendation as to what to do.

  • Looking for a crop that will allow me to keep all the heads the same size

    looking for a crop that will allow me to keep all the heads the same size. Iam a School photographer and have been looking for a crop tool mask out liner ect that will alow me to crop and see that head sizes remain the same throught out a job can any one help with this question?

    I *think* I'm understanding that Eisenray is asking. Similar to the crop overlays, like Grid or Spiral, he would like one with an oval, to help hi better size the heads in the photos. I believe in each photo, the heads have to be the same size.
    What he *could* do, is create a rectangle with an oval punched out of it. He could drag the image to an 8x10 300ppi document, and that rectangle can be overlayed on his photo, then he can shrink/enlarge the photo to fit the oval...if that makes sense.
    It's difficult to understand, do if I'm wrong, please let us know, Eisenray.

    There are many ways and applications that you can use to build a web site. Which will be best for you will depend on the site you want to build and your level of expertise. Many experienced web developers just use a text editor, often one with specialized features for web programming (BBEdit, for example), but there are programs that can offer additional help, up to and including "drag and drop". Without knowing more about your needs, it's difficult to offer specific advice, but here are some possibilities:
    iWeb - came with your Mac. Easy to build but rather limiting in what you can do.
    RapidWeaver - more flexible and capable than iWeb but harder to use; sort of an "inbetweener" application
    Dreamweaver - powerful but expensive and a steep learning curve
    There are of course a number of other options. If you can provide more detail about what you wish to build and your level of experience, someone can probably make more targeted recommendations.

    lllaass is correct.
    To use ThunderBolt devices, a computer must have left the factory with a ThunderBolt port.
    There are no known work-arounds, and there are not likely to be any because Intel controls the chips and is not interested in anything less than the full [including Video features] implementation.
