[Issue] How data is transferred when you use BlackBerry (NFC) Tag? WiFi Direct? Bluetooth 2.1? Bluetooth 3.0?

Hello

I saw a bunch of videos of demonstration of tag BlackBerry of all the cool things you can do with the NFC, but it wondered, what happens if all my other antenas wireless, WiFi and Bluetooth, are out of?

NFC can be used to transfer data, but it is not good for large quantities. I looked a little further and I found this cool video showing the difference to use Bluetooth 2.1, Bluetooth 3.0 high speed and Wifi Direct to transfer large files, such as videos. BB10 already does support Wifi Direct? Bluetooth 3.0 high speed?

I hope that BB10 supports ALL the performance and maximum compatibility.

I don't know where to post this question so here's. Please move was a better place. I think that the community needs a session of general development for wider issues.

See you soon!

Hello

Tag BlackBerry, and the APIs available for developers will automatically perform the best way to transfer the data. NFC supports something called "connect transfer" and are the largest payloads or certain types of data (photos, for example) rather than by peer-to-peer NFC, NFC mode data transfer is just used to negotiate alternative transport. In the case of the BlackBerry smart phones, this alternative will be bluetooth.

For users of touch devices, there is a brief 'conversation' between the devices on the NFC and this translates into a bluetooth connection set up and data transfer initiated through the bluetooth connection faster. This is all without the usual matching process. After reaching the stage of bluetooth devices need closer will be of course.

The same principle applies to both 7 BlackBerry and BlackBerry 10. In fact talk us a bit about this in our latest article on BlackBerry 10 NFC API:

I hope this helps.

    Thank you

    Be more specific.

    You try to insert this in a column that is defined as not null?

    If so, you can choose a default value for the value that you want to use if the user leaves the field to the white screen.

    Or, better yet, use the validation of the front to prevent them from going into an empty space (or perhaps failed it there).

    However, if you still want to do it in the DB:

    values (to_date (nvl (?, '' 2199/12/31), "dd/mm/yyyy"));

  • Issue of Oracle SQL Developer when you use VPN (Cisco)

    All,

    We have a somewhat obscure issue with connectivity SQL Developer to our databases of the laptop has distance from the employee.

    The database is hosted inside our firewall and when the employee is trying to connect to the database that it receives the following error message:
    + "Encountered error: an error has occurred to perform the requested operation: the network adapter could not establish the connection." Code provider 20 "+"

    I think maybe I saw the error at some point as well...
    Status: Failure-Test failed: IO error: the network adapter could not establish the connection

    Note: It gets this error when you are connected to our VPN & so that it can connect through SQL * more on that same basis. It gets the error without worrying if he uses the option to enter tnsnames in SQL Developer or if it uses the "basic" connection type

    What is interesting, is that if he disconnects the VPN, will turn off its wireless connectivity, then hard-wire in our network, it can connect, without issue.

    The strangest part for me, is that although it cannot connect to the database using SQL Developer, it can connect through SQL * more. It can ping the IP source address very well, he can tnsping database without problem, it can connect through SQL * Plus, it just cannot connect through SQL * Developer. Since SQL * more and tnsping work, I know that it can access the db server through port 1521, so I don't think it's a problem of port.

    Another weird thing: when it connects to our network via a 'old' virtual private network (VPN open) there is no problem.

    His machine is Windoz 64 bit (HP laptop) and it uses the latest version of the SQL Developer and a JAVA virtual machine.

    Also interesting: I also have a Windoz 64 bit computer laptop (Lenovo) and I don't have the same issues, as it does. I am however running an older version of SQL Developer and probably an older JVM.

    I dug around a bit, looks like maybe it has something to do with IPv6? No idea what to do next, except have my network guy look at the logs of firewall to try to grasp where the connectivity has been ignored.

    Any ideas or suggestions would be appreciated. I tried all sorts of things (giving him my file tnsnames.ora and sqlnet.ora, manually editing these files, try IP addresses instead of host names, host names I tried with the doman.org extensions, etc.).

    Still, any suggestion would be appreciated and I thank very you much.

    If it is IPv6, you can try adding

  • How update the content when you use SGD - CD?

    I managed to create a deployment for a presentation and then at the request of the URL (go to) to play.  It works very well.  My question is, when the content is being updated, make the changes to the presentation automatically updated on the flash memory or do I have to re - deploy the application?  I'm wading through the documentation and can't seem to get a clear answer on this.  I see something under the mounting of a deployment package that says:

    Step 8 (Optional) would you like to repopulate this deployment package?

    Repopulate and save now.

    When I change my deployment package, I see nothing that says repopulate.  Any help is greatly appreciated!

    Thank you!

    You may or may not use the game in the future. This isn't an obligation to update deployment packages.

    Regarding the deletion of old slides, it should overwrite files same htm if you just update a presentation, but if you completely change the contents he cannot remove the one according to which files are part of the presentation.

    In addition, if necessary, you can ftp on the IP of the DMP and delete old files of presentations as you want. They must be under/usb_1/deployment/content.

  • Data is encrypted when you use SQL * Net

    Hello

    I'm curious to know if the data that is transmitted through SQL * Net is encrypted or clear text - which means that it will be possible for someone read data that is sent from database to log on user or vice versa.

    Thank you
    SS

    I'll change the response of sb92075 to say that the transfer of normal data packets aren't encryped by default however the advanced security option can be used to encrypt all packets of sqlnet.

    I also believe that oracle encrypts the password in a package of authentication.

  • Stray WiFi by default, when you use the Fn + F3 WiFi on request (AODD270)

    The netbook (Win 7 starter) allows the WiFi feature on every start upward.  To save energy, how can it be turned off?

    I mean, it is, is there a way to remove the default WiFi and turn on only when I need, via the Fn + F3 command.  I don't want to have to turn off after starting upwards, it must be turned off by default.

    I looked through the BIOS and other parameters, but found nothing.  I tried net looking for a solution, but nothing helped.  I guess I could turn it off the network device, but it's just an approach long drawn to something that should be simple enough.

    The Fn key commands are accessible via a script .bat by chance.  He has a work around, but I could turn off the WiFi and also the pavement at startup automatically, by adding a .bat script to the registry to run at startup.

    A bit more technical than the usual post problems, but good.

    Congratulations for all the suggestions.

    Please do not post duplicate applications.

    I will summarize the issues here:

    1. How can I turn off WiFi at startup?

    2. How can I disable the touchpad on the boot?

    3. is it possible for me to programmatically control the Fn keys to do the above?

    We ship systems with everything by default.  It is the presumed position that our customers prefer to have all the material available and functional when the system starts.  If the system devices are off at the start, he won't see the device until it is powered, causing other possible problems with the feature.

    1. & 2. We do not recommend or provide a way to disable these devices by default.

    3. we do not ease for the capabilities requested by the programmatic use of the Fn keys.

    You will notice that if you disable the touchpad or the NIC wireless with Fn keys, it does NOT get disabled in Device Manager.  It is part of the overall design of the system.  It is not part of Windows or in the Windows registry.

    You can make sure the system is running the power system and power all the saving options are checked for devices you want to be turned off by power controls.

    Other than that, a quick tap of the Fn + F3 or Fn + F7 to disable wireless / touchpad as needed.

  • BlackBerry smartphone screen locks when you use Blackberry "BOLD"

    I administer a BES Blackberry Manager 4.1 running. We have a policy of lock screen that hangs on the screen after 30 minutes of inactivity. We have recently migrated to the Bold 9700 devices.

    Here is my code, I don't know how to move forward on this issue. Well, any help would be apprciated.

    Right.

    It is therefore being truncated when it is read in the DB.  Nothing to do with CFXML.

    Looks like it is hitting the size of the Long text buffer (which by default is 64 KB).  Increase this value (in your DSN settings, advanced).

  • Join external condition bug/feature when you use a RC?

    First I picked up on this bug/feature in an article in the blog of Armstrong ([http://learndiscoverer.blogspot.com/2008/05/using-case-to-solver-outer-join-issues.html])

    It seems that when you use an OR condition in Disco as well as 10 g, it ignores the join on the table conditions...

    I've included the two reports the SQL code to illustrate my point:

    Here is the SQL code generated when I agree with the point of view, you will notice the outer join (i.e. "(+)" ")
    SELECT O100288. UNIQUE_ID, O100291. UNIQUE_ID
    OF ODSTHING. TABLE1: O100288, ODSTHING. O100291 FROM TABLE2
    WHERE ((O100291. UNIQUE_ID = O100288. UNIQUE_ID (+)))
    ;

    Here's what happens if I simply add that a condition is not null. Notice the outer join on the 'IS NOT NULL' which allows to do nothing
    SELECT O100288. UNIQUE_ID, O100291. UNIQUE_ID
    OF ODSTHING. TABLE1: O100288, ODSTHING. O100291 FROM TABLE2
    WHERE ((O100291. UNIQUE_ID = O100288. UNIQUE_ID (+))) AND (O100288. UNIQUE_ID (+) IS NOT NULL)
    ;

    This is what happens when I have AND the same condition with himself, he remains outside joined
    SELECT O100288. UNIQUE_ID, O100291. UNIQUE_ID
    OF ODSTHING. TABLE1: O100288, ODSTHING. O100291 FROM TABLE2
    WHERE ((O100291. UNIQUE_ID = O100288. UNIQUE_ID (+))) AND (((O100288. UNIQUE_ID (+) IS NOT NULL AND O100288. UNIQUE_ID (+) IS NOT NULL)))
    ;+

    Here's what happens if I have the same CONDITION with himself. MAGIC! The outer join disappears!
    SELECT O100288. UNIQUE_ID, O100291. UNIQUE_ID
    OF ODSTHING. TABLE1: O100288, ODSTHING. O100291 FROM TABLE2
    WHERE ((O100291. UNIQUE_ID = O100288. UNIQUE_ID (+))) AND (((O100288. UNIQUE_ID IS NOT NULL OR O100288. UNIQUE_ID IS NOT NULL)))
    ;

    Is it the way it is supposed to work? If it is then I don't see any trace of it in the documentation ([http://download.oracle.com/docs/html/B13915_04/conditions.htm])

    Is it just a useful bug?

    What people think about its use?

    Hello

    It is documented (http://download.oracle.com/docs/html/B13916_04/conditions.htm#sthref854) that the discoverer does not use outer joins with IN and OR conditions. But the implications of this are not stated. The documentation never tries to explain the underlying SQL.

  • When you use a left and right axis, how to choose what issed axis for the value of y GetGraphCursor?

    I use a graph with a left and right axis (2 data sets).  I try to use a slider to select a point in time (x) and the values of y in the two sets of data.  I can't understand how the control, the value that is returned for the value is when you use the GetGraphCursor call.

    GetGraphCursor (panelHandle, PANEL_GRAPH, yourCursorNumber, & x & y)

    Using SetCursorAttribute with the attribute ATTR_CURSOR_YAXIS must be what you are looking for. The online help for this attribute explains wery well:

    Description: Used to change the y-axis which is associated with the bar graph.
    When a graphics cursor is created, the Y axis with which it is associated is determined by the value of ATTR_ACTIVE_YAXIS.  Subsequently, the association can be changed using ATTR_CURSOR_YAXIS.
    The y-axis associate serves as reference for the coordinates of the cursor position in calls to SetGraphCursor and GetGraphCursor.

  • How to disable direct sound when you use a plugin for guitar?

    I use the Waves GTR plugin for recording guitar in Logic Pro X, but because it puts a lot of pressure on the CPU, I tried he governs through a "bus" instead of having the plugin separately on every guitar track. The difference is that when I use the bus option, I can't seem to get rid of dry direct sound which is obviously very embarrassing. The only way for me to get rid of the direct sound is to use the RTM plugin on every guitar track that quickly causes the overload program when using several of these titles.

    Anyone know how to get rid of the direct sound when you use the alternative of bus for the guitar tracks?

    just at the exit of the guitar channel strip no output. This way you won't hear at the follow (because the dry track will not be transmitted to any output)
