Is there a limit on Channel that can be added to selector

I have read in an old document on javaworld that there is a limit of 63 channels that can be registered with a Selector. I assume I can create multiple Selecors, if I have to manage more than 63 channels and try to select on each one after the other.
However, I still want to know whether this limit is there as I did NOT see it in any NIO documentaion.
I quote from the below article -
"Fourth, a selector can have only 63 channels registered, which is probably not a big deal. "

This was a Windows-only limit in JDK 1.4.0. If you are not on Windows, or are in 1.4.1 or later, there is no limitation.

    Hi Munirathinam,
    We can use transport rule and content filtering to implement this function, for example "SubjectOrBodyContains" or "

  • Are there any free TV channels that can be received on the Apple TV?

    Are there any free TV channels that can be received on the Apple TV?

    No, it's not a TV tuner.  It's primarily marketed as a rental vehicle for iTunes store movies/purchases and for playback of compatible (see specs) media from iTunes.
    Some subscription streams are available eg Netflix, MLB as well as youTube and some limited internet content (no browser).
    Check the Apple tech pages.

  • Is there a quick delete button that can be added next to emails?

    When reading through emails in Thunderbird there are some emails that I know I don't want to read and would rather quickly delete them without having to click on the email itself.
    What I am looking for is a quick delete button similar to the 'star' button that can be added as a column. I would like a button that sits next to message titles in the email pane that allows me to quickly delete messages.
    Microsoft Outlook (windows mail) has something like this on all messages and I would like if that functionality would be replicated in Thunderbird.

    Are you saying that features and design of other software should not be adopted by Mozilla software? I think the past few years of Mozilla software would highly disagree.

  • Is there a limit to what it can handle?

    I have a LR catalog of about 700gb. I have about 1tb of videos that I'd like to add. Will LR slow down at some point if you add too many files? Is there a limit to what it can handle?
    Thanks.

    Your files are not stored in Lightroom, so the size and amount of files does not affect Lightroom's performance. Lightroom is simply a database, it knows the location of your photos and videos. Thus, there is no limit. And people report catalogs of over 1/2 million items running properly.
    Tom Hogarty, one of the developers of LR, says as much in this video at about 18 minutes: https://plus.google.com/events/c8trrra6064daff60ul6ukltleo

  • Is there a stereo bluetooth headset that can pair with more than one device at a time?

    Is there a stereo bluetooth headset that can pair, i.e. multipoint, with more than one device at a time?
    Are the MacBook and iPhone 4 capable of multipoint bluetooth technoloagy?
    The goal is for my wife to be able to watch her Korean TV soap operas on her MacBook and still receive a call on her iPhone 4 via a stereo bluetooth headset.
    I was looking at the Motorola S10-HD but after further review saw that it only pairs with one device at a time.
    Appreciate any and all input. My Googling has returned no results.

    You can only pair one device at a time to your 8330, or any other phone for that matter.  The "pairings" are saved to the phone, you can use one or the other and you won't have to pair it again.  Once you turn your bluetooth device on and the phone is on, they will find each other again.
    Hope this helps,

  • Is there a version of PS that can adjust a batch by a Historgram setting?

    Is there a version of PS that can adjust mass numbers of high res images for Contrast and Brightness but at the same time constrained by a Histogram setting?
    I have thousands of hi res .sid or .png images that are all of various degrees of brightness and need to be brightened to different degrees along with contrast changes.  Although it can obviously be done individually, I am seeking a batch command that can do this without over correcting.   Is there any PS version that can analyze each photo and make brightness and contrast corrections but constrained by a histogram setting?  Because some photos need twice the brightness or contrast than others, using that batch same command will result in many of the photos being over corrected.  Thus, I am looking to adjust via an auto Histogram analysis of each photo to avoid over correction.  Is there any software that does this?

    Yes, it can be installed on a network. I teach Dreamweaver at a university in London, so I know that it definitely works. But I'm not a systems admin, so I don't know the details of how it's done. However, the following should be a starting point for your sysadmin: http://www.adobe.com/devnet/creativesuite/enterprisedeployment.html.

    Hi,
    Windows has a function called Narrator. Narrator reads what is displayed on the screen, including the contents of the active window, menu options, or text that has been typed. Narrator is designed to work with Notepad, WordPad, Control Panel programs, Internet Explorer,
    the Windows desktop, and some parts of Windows Setup, and may not read words aloud correctly in other programs.
    For more information, please refer the following link:
    Turn on and use Narrator
    http://windows.microsoft.com/en-IN/windows-xp/help/use-narrator
    In addition, based on my research, a kind of third party program named JAWS. You could know well it first, and then decide whether you want to buy it.

  • Is there any app or something, that can do that, you can stream any sound coming out of your mac to your airport express?

    Is there any app or something, that can do that, you can stream any sound coming out of your mac to your airport express?

    Yes, he would have to have jailbroken your phone to install malware. If you see an app called "Cydia", that would indicate conclusively that it was jailbroken. I would recommend restoring the phone as new using iTunes. It is your best shot at removing a jailbreak.
    You should also change your network password, your email password and your FB password as well as passwords to anything else you've used from the phone. Put a lock code on the phone.
    Your best defense against this sort of thing is to NOT give your phone to people you don't trust.

    I've heard good things about JasperReports (theres a link on the first results page from the above Google search) but I haven't used it myself.

  • I've just bought a new mac and I want to transfer the content from my old Macbook to my new. If I have iCloud enabled on both devices, is this simple, or is there a limit to what I can transfer? For example, can I upload word files to iCloud?

    I've just bought a new mac and I want to transfer the content from my old Macbook to my new. If I have iCloud enabled on both devices, is this simple, or is there a limit to what I can transfer? For example, can I upload word files to iCloud?

    iCloud is not the way to do this. You should use Migration Assistant - with this you can transfer your complete User folder from the old Mac including preferences and logins. You will need to connect the two with FireWire or USB depending on the models.
    Ideally you should do this before you set up the new Mac - if you create a user account with the same name than the Migration will have to give the migrated user folder a different name. When you first switch on the new Mac it should ask you if you want to transfer your data, and give you instructions.

  • Is there any iPhone midi controller that can control logic just by one usb

    is there any iPhone midi controller that can control logic just by one usb line to the mac?
    Free ones would be the best!
    Thanks!

    If you have a Mac Pro and an iPhone, surely you can afford a router? It's about the same price a a decent meal for two.

  • Is there any iPhone midi controller that can control logic just by USB?

    is there any iPhone midi controller that can control logic just by one usb insert to the mac?
    Free ones would be the best!
    Thanks!

    Although not USB, there are a couple of iPhone/Touch apps that can control the Mac using a wireless network. MobileMouse (free & paid versions) do a great job, as well as Logitech's TouchMouse. Both will allow you to use the touch screen to control the mouse, which essentially gives you the ability to do many things in Logic. I've used them, for example, to begin a recording, which frees me from being near the computer.
