We want a single-crowned cccy tech

After reading Java Concurrency in Practice by Goetz et al, I have come to think that current Java concurrency technology is double-crowned. One is thread safety, which is naturally convincing as a programming rule and care. Another is visibility, which is nothing but an issue borne by optimization artifacts from underlying low-level systems.
I think the visibility issue should be completely transparent to the user of high-level language. Programmers suffering and taking much care for such issue is felt quite unreasonable and counter-productive because they/we just want write code in a human-readable language which could be run as its natural, or common sense, semantics could assume.

If you don't care about performance then you need only deal with locks and can ignore any visibility issues. Real world programs need to push the performance envelope and they want atomics, lock-free data structures etc where visibility and ordering are crucial.

  • Want a single .swf like before

    I just want a single .swf like I iused to be able to publish
    out of v1 of captivate. Is there a way to do that?

    Hi again qptress
    Captivate 3 brings quite a wealth of new features to the
    plate. You have already mentioned grouping. But there are others,
    such as;
    * Ability to randomize, copy, paste, import, export question
    slides
    * Two new question types
    * Ability now to automatically size text buttons
    * New object type called a "Slidelet", that allows
    presentation of a Caption AND an Image on the same mouseover
    * New mode of recording audio narration - You may now watch
    the slide or project play while you narrate
    * New "Multiple mode recording". You may now record a single
    time and create both a Demonstration and a Simulation based off the
    single recording.
    There is more. I'm just hitting the high points.
    As for the full motion bits, it certainly sounds like you
    launched Captivate, selected the "Full Motion Recording" mode and
    recorded your project. Certainly, when you do this you will end up
    with multiple .SWF files to distribute.

  • Want a single entry for alarms in the "AlarmsWindow"

    Hi,
    I have an alarm in Lookout that comes in fairly frequently.  This is normal for this alarm, it comes in and out of alarm by itself.  After the alarm clears itself it becomes blue (the unacknowledged color).  When the alarm goes back into alarm it is displayed in the "AlarmsWindow" on a new line.  So after getting this alarm eight times I will have 8 entries in my AlarmsWindow. 
    How can I make it so that I will only get a single entry in the AlarmsWindow per alarm?
    I have tried the following paramenters in the Lookout.ini file, but they don't seem to do anything.
    [Alarms]
    MostRecent=1
    OldAlarmsLimit=0
    I edited the file in my Lookout4 directory and then restart lookout.  I have also tried restarting all the the Lookout services...  with no lock
    Please help,
    Thanks.

    Thanks for the reply!...
    Actually, I'd prefer not to use auto acknowledge if it can be avoided... precisely for the reason you've mentioned.  (i.e. because it is a global thing...)  I don't want my other alarms to auto acknowledge. 
    Ideally  I would like there to be a way for there to be just a single entry for an alarm, where the time stamp would update whenever the alarm is active.
    The problem is that my customer has a pressure gauge that they monitor for low pressure... but at certain times of the day the pressure readings will bounce around the setpoint level for the low pressure alarm.  For example, if the pressure setpoint is 70 psi, then we might see a period of time where we get 100 alarms because during that time of the day the pressure fluctuates between 68 and 73 psi frequently.  All these alarms flood the "AlarmsWindow" making it hard to see other valid alarms.  So the customer would like to see just one alarm entry for ALL occurances of the pressure alarm.
    It sounds like the .ini file entries I mentioned should do just that, but when I try it nothing different happens...  is there something different I have to do to get those .ini entries to work?  Has anyone had success with thise .ini entries?
    please help... thanks!

  • Is there a simple way to put two pieces of music together seamlessly? I just want a single, longer track.

    The music is 3:14 long.  I want to repeat it...seamlessly...withount a second or so hole between them. It's for  slide show background.
    I am definitely not a musician. But I figure I can do this in GarageBand.
    Thanks!

    OK... if it's the top right corner of the work space (the place where the track lies) where do I drag it to? Forgive me, but I'm not a musician, I'm a writer. To me, it's the "top right corner" there's no place for me to drag it to... except down or to the left.
    FYI:  The music is a very simple acoustic guitar solo.  The medium beat is clear and the point at which I'd put the two pieces together is equally clear. It's a pleasant piece.  Now you know as much as I do about the music.
    Thanks.

  • Want single tab close x - how can this be set up?

    In versions after 30.0 the tab close x appears in every open tab. I want a single tab close x located at the right end of the tab toolbar. The about:config code to set the value = 3 no longer is accepted. What is the new way to create a single tab close x ??

    Killing the close x in each tab is only part of the solution. The rest of the solution would involve reinstating what used to be about:config where the browser tab close value = 3, which put the single close x under the app close red x on the right hand side of the window at the right end of the tab toolbar. I'll stick with version 30.0 where this was last supported until such time as the code is restored, or I'll find another browser.

  • 9ir2 Single Node RAC + RH80

    Hi all.
    I'm triying to install a single node RAC based in the single node rac for linux document in the metalink.
    The document was made based in a oracle 9iR1 database an RH71, I have followed the steps and i have a working kernel made by my own, the raw devices, and softdog hacked for being testing only. But the service does not go up.
    I don't know if someone have made a single node rac instalation and can help me to choose the right pieces.
    I don't have a RHAS2.1 but I do have a UnitedLinux 1.0 Server Patched.
    I want to try the RAC tech but here (ecuador-sudamerica) is dificult to find firewire cards and disks so I´m working around a single node instalation.
    Any help will be apreciate.

    Hi
    Database version and GI versions are 11.2.0.2.2. And these are not multinode RAC configuration at any given time only single instance will be there for any given database. Some thing like ACTIVE and PASSIVE in hardware clusters such are VCS (Veritas Clusters).
    I agree with you failover sinario in multi node (2 or more) RAC environments. In single node clustering only one instance will be there, like services in multinode, here whole instance will be re created on available nodes.

  • Bios settings for single SATA Drive Help

    I have just installed a 945P Platnium mother board with a Pentium 4 3.4 extreme with HT tech.
    I have 2 GB of memory, nvidia 1 gb video 9800 GT, I have 2 IDE hard drives: WD 320 GB(C:) and WD 120 GB (E:) and a CD/DVD drive (F:). I installed a WD 500 GB SATA drive on SATA 1 and the two IDE hard drives on IDE 1 on the same cable with the 320 GB as master and the 120 GB as slave. The CD is on IDE channel 2 as the master.  I have cloned the IDE 320 (c:) to the 500 GB Sata which is now the boot drive (c:).
    I have been able to boot the computer but the CD/DVD drive doesn't show. If I unplug the the hard drives and reboot then the CD/DVD drive shows up.
    My question is: I want the single 500GB sata as the boot drive (c:) (don't need RAID?). I want the two IDE drives with the 320GB as drive (e:) and the 120GB as drive (whatever) and the CD/DVD drive to show up as (F: or whatever).
    I don't know what settings in the bios I need to be working with. I have been experimenting but would like the correct way to set the bios up.
    Thanks

    Nope. Didn't work.
    I can try things all day but this doesn't make sense. Surely someone knows what bios settings are required (especially on the MSI board site) to set the bios on a MSI 945p platnium motherboard. I have the sata drive plugged into the Sata 1 connector and bios still says it is ide channel 4 master. The computer will boot with just the sata drive plugged in but the problems start when I plug the ide drives in on ide 1 or 2 or 3.

  • What is the best way to aggregate photos from multiple family users into a single iCloud photo library?

    My wife and I currently have a iPhone and iPad each.
    We share my apple ID account for apps and I also use this as my main icloud account on my devices.
    My wifes devices have a different main icloud account.
    We also have a iMac with separate users configures, which are tied to our individual icloud accounts.
    Now that OSX photos has been released we want to make use of it including icloud photo library.
    We take photos. Lots of them.
    And we want the photos from all our devices to be aggregated automatically into a single osx photos/iCloud photo library.
    1 - because we want a single library which includes all our photos from the last 15 yrs
    2 - because we don't want to pay twice for storage
    Seems to me there are two options - but I would be happy to hear any others.
    1) The family sharing route
    This seems to be the official solution, but it has major limitations.
    Set up family sharing. I'll be the organiser since its my apple id thats used for app purchases already
    Add my wife to the family
    Ah... but now she has to manually share every photo or moment from he device
    And it seems that these moments are not incorporated into the photos database in same way as the icloud library account users (me) are
    2) Family iCloud account
    I didn't test it yet, but no reason that I can see why it should not work
    Create a new icloud account for the family
    Make this family account the primary icloud account on all devices (could be a big disruption for icloud enabled apps)
    Add our personal apple ids as mail/contact/calendar account
    Make a new user on OSX for photos which has the family icloud account configured
    No all devices should share the same photo library
    Unfortunately:
    We lose bookmark, keychain, etc sync between devices and osx accounts
    We lose imessage (maybe).
    We lose the new ios8/yosemite features like handoff
    Or worse we get crazy imessage/handoff between all devices from all accounts
    Both methods have major downsides.
    Anyone know of a better way?
    Why doesnt apple allow multiple separate icloud accounts to be configured and select which features each can use (where some features may have to be unique to a single account). To me this would seem to be the best option...

  • I used the migration assistant to transfer files from my PC to my Mac but it recreated my user profile from the PC and I wanted to transfer the files to the new different user profile I've setup on the Mac. How can I transfer everything now?

    I have an older Windows laptop and I am switching to a new MacBook Air. The main user on the Windows laptop is going to be different than the main user on the MacBook. I used the migration assistant to transfer data to the MacBook but it recreated the whole older profile on the new Mac when I just wanted to pull everything over into the new user profile I had already created on the new MacBook. How can I go about putting the data over into the new user profile and erasing the older other user profile it recreated? Would I erase the old user profile on the new Mac and start over with the migration assistant using some setting I missed that lets me pull the data over to the new main user on the MacBook? Or is there a way to rename the old user profile on the Mac to match what I want the new username/password to be somehow?
    Or would it be best to back the data I really need from the old PC onto an external HD and then copy it over to the new Mac from the external HD?
    Looking for advice on how to best go about this. On the old PC I had multiple profiles and it was awkward. On the new Mac I just want a single profile for the primary user and both users will just share the same user profile. I wasn't sure if the Migration Assistant only let you recreate entire profiles or if there was a way to just import data from the old PC's primary profile into the new Mac's new primary profile with some setting adjustment.
    Data would be docs, pics, bookmarks, music. Fairly basic.
    Thanks for any and all advice,

  • Combining filled forms into a single PDF

    Hello-
    I'm having some trouble combining some documents. I have a source PDF file, 'Service Form', that I use to fill out and save as a separate form by customer. For instance, I open 'Service Form', fill it in and save it as 'Customer A' form when completed.
    Now, if I try to combine 'Customer A' form and 'Customer B' form in to a single PDF, 'Customer B' form gets populated with 'Customer A''s data. In other words, I have two 'Customer A' forms. I have tried many different ways to save and combine them but nothing works.
    I don't want to create a PDF Package, I want a single PDF with multiple instances of 'Customer' forms.
    Anyway, I'm sure this is clear as mud. Any feedback is appreciated.

    You can flatten a file using the flattenPages() JavaScript method. The advantage to flattening is you can use JavaScript in a batch process to automate the process of flattening a large number of files.
    As a test to see how it works, you can open a copy of one of the forms in Acrobat, activate the JavaScript console (Advanced > JavaScript > Debugger), and enter the following in the code window:
    flattenPages()
    and hit CTRL+Enter (with the cursor on the same line as the code)
    and save the resulting modified PDF.

  • Record Working Time task merging multiple employees into a single task

    Hi Everyone,
    I'm going to check our configuration again to see if this is standard behaviour, config, or a problem with EHP 3's version of record working time.
    So if employee A submits to manager A 1 task is created.  Then when employee B submits to manager A we were expecting 2 tasks.  However, we've been noticing manager A is getting 1 task with several line times. 
    We are ok with it merging tasks for employee A over multiple weeks.  That is ideal actually.
    The problem is that employee B's task should be separate.
    Is there a quick fix?
    Thanks,
    Doug Robbins

    I did try 31000007 and noticed the same behavior.  Are you saying I should use an older version of the task to get back to grouped by employee number and not merging everything? 
    Well this causing us issues for a few reasons. The main one we developed a work around because we had to make sure emails were not being sent to 1 person for all the employees with their data.  That would cause obvious security concerns. 
    But when forward tasks out managers want to be able to forward a specific employee's requests and not all of them.  If some customers want this it should be a configurable option.  To allow companies that want 1 single task or companies that want 1 task/employee/week.
    This is inconsistent with the other portal applications.  It would be nice if Germany picked 1 way of doing things or provided more configuration options.  I'm hoping that OSS gives us something because merging everything into a single task for all employees is not the behaviour we want or expected.
    I always appreciate your input because you have been very helpful as I learn about portal.
    Thanks,
    Doug R
