36,988,817 | 0 | <p>In what I say below, KAAZING_GATEWAY_HOME represents the directory in which you installed the Kaazing JMS Gateway.</p> <p>There are several moving parts - the client, the Kaazing JMS Gateway, and the EMS back-end. The problem could be the Kaazing JMS Gateway connecting to EMS on the back end, or there could be an issue with the client trying to connect to the Kaazing JMS Gateway. There is not much detail yet. In order for us to troubleshoot, one way to provide more detail is to make the logging on the Kaazing JMS Gateway more verbose.</p> <p>The log is by default written to KAAZING_GATEWAY_HOME/log/. There are several there but the main log is error.log. Its default LOG4J configuration is in KAAZING_GATEWAY_HOME/conf/log4j-config.xml. You can get more diagnostics for the connection issues on both ends by replacing the contents of that file with the following (you can make a backup copy to restore the default log configuration later):</p> <pre><code><?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE log4j:configuration SYSTEM "log4j.dtd"> <log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/"> <appender name="ErrorFile" class="org.apache.log4j.RollingFileAppender"> <param name="File" value="${GATEWAY_LOG_DIRECTORY}/error.log"/> <param name="Append" value="false"/> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%d [%t] %-5p %m%n"/> </layout> </appender> <appender name="STDOUT" class="org.apache.log4j.ConsoleAppender"> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%d [%t] %-5p %m%n"/> </layout> </appender> <logger name="transport"> <level value="trace"/> </logger> <logger name="com.kaazing.gateway.jms"> <level value="trace"/> </logger> <logger name= "service.stomp.jms"> <level value="trace"/> </logger> <logger name= "service.jms"> <level value="trace"/> </logger> <root> <priority value="info"/> <appender-ref ref="ErrorFile"/> <appender-ref ref="STDOUT"/> </root> </log4j:configuration> </code></pre> <p>Once you have copied that in place, try connecting again. If you see no logging in the gateway for the connection attempts from your client, it means there is an issue in the client code or configuration, between the client and the gateway, or on the client machine itself. Otherwise, please share the results of updating this. The results should be time-stamped so you can tell which log entries correspond to your attempts to connect.</p> <p>You can share your logs here, or directly to me at the address below.</p> <p>Please keep us posted.

1,728,706 | 0 | <p>The <code>start</code> event is a tricksy faux one. What you need to do is attach your code to cancel event bubbling directly to the <code>mousedown</code> event of the <code>ul</code> itself, and make sure your event handler is executed first.</p> <p>You'll see in the jQuery docs for <code>event.stopPropagation</code> this little line:</p> <blockquote> <p>Note that this will not prevent other handlers on the same element from running.</p> </blockquote> <p>So, whilst <code>event.stopPropagation</code> will stop the event bubbling any further up the DOM, it won't stop the other event handlers attach to the <code>ul</code> being called. For that you need <code>event.stopImmediatePropagation</code> to stop the <code>selectable</code> event handler getting called.</p> <p>Based on the <a href="http://jqueryui.com/demos/selectable/" rel="nofollow noreferrer">selectable demo page</a>, this code snippet successfully cancels the bubble:</p> <pre><code>$(function() { $("#selectable").mousedown(function (evt) { evt.stopImmediatePropagation(); return false; }); $("#selectable").selectable(); }); </code></pre> <p>Note that you must add your event handler to the <code>ul</code> object <em>before</em> you execute the <code>.selectable()</code> setup function in order to sneak in and pop the event bubble first.</p> |

19,934,143 | 0 | <p>regarding pointer type: the idea here is that in order to reduce both loop and copy overhead, you want to copy using the largest data "chunks" (say 32bit) possible. So you try to copy as much as possible using 32bit words. The remainder then needs to be copied in smaller 8bit "chunks". For example, if you want to copy 13 bytes, you would do 3 iterations copying 32bit word + 1 iteration copying a single byte. This is preferable to doing 13 iterations of single byte copy. You could convert to uint32_t*, but then you'll have to convert back to uint8_t* to do the remainder.</p> <p>Regarding the second issue - this implementation will not work properly in case the destination address overlapps the source buffer. Assuming you want to support this kind of memcpy as well - it is a bug. This is a popular interview question pitfall ;).</p> |

32,450,553 | 0 | <p>There's a different behaviour for push notifications when the app is in the foreground/background and when the app isn't running at all. When the app is running, whether in the foreground, you'll receive a call to <code>didReceiveRemoteNotification:</code> and you'll be responsible for handling the notification's display (the operating system won't do it for you).</p> <p>When the app is in the background, you'll receive a call to <code>didReceiveRemoteNotification:</code> only if/when the user presses the notification banner/alert displayed to him/her by the operating system. If the user chooses not to interact with the notification, your app won't even know about it.</p> <p>If the app isn't running at all, the behaviour will be similar to when the app is in the background, only you'll receive the push notification indication and data in the userInfo dictionary of <code>application:didFinishLaunchingWithOptions:</code></p> <p>So, if your question refers to cases in which the app is in the foreground, that shouldn't be a problem and you can do anything you want with the alert field before displaying it to the user. Otherwise, it's the operating system's responsibility to show the alert so that makes it a bit more complicated.

13,636,694 | 0 | <p>If I've understood it correctly you don't have any problems of library versions and isolation, so independently of if a library is used by all the war archives or not, you can place them all inside the ear's lib directory (you could even consider placing the libraries in the jboss instance lib directory, and removing them from the ear/wars!). This way the ear file will have the smallest size possible.</p> <p>Don't worry about the memory used, the JBoss classloader will just load once the libraries, so they will be shared by all the wars that need them (another case would be if you need a different version of the same library for each war).</p> <p>On the other hand, if any of the libraries is just used by one of the war file, it will also be optimal if you place the library inside this war's lib directory.</p> <p>So your first approach is right, I don't think you need to change it.</p> |
5,160,906 | 0 | <p>When doing performance tests like this, you should always allow for "warmup period". So you shouldn't start measuring before having run the calculations a couple of hundred or thounsand times. This way the Java Hotspot compiler will have compiled what it considers being frequently executed code, and the native binary will have put its most frequently used variables in processor registers.</p> <p>My guess is that close to 100% of the difference in your result is due to the slow startup time of the JVM. Java uses ages to start compared to a natively compiled program.</p> <p>It would be interesting to see a measurement actually done in code, after a "warmup period".</p> |

16,418,755 | 0 | <p>The entire difference is like you said, in texture caching. So choosing between either of these methods depends on whether or not you will want to exploit texture caching in your visualization. Lets look at some common cases:</p> <p>a) If you want to calculate how a surface is deformed (for example the surface of water, or maybe some elastic deformation) and you need to know the new vertices for the surface's polygonal mesh then you would typically use Buffers (Number one), except you wouldn't need to copy to an OpenGL texture here. In fact there would be no copying involved here, you would just reference the buffer in CUDA and use it as a gl buffer.</p> <p>b) If you have a particle simulation and need to know the updated particle's position, you would also just use a buffer as in the above case.</p> <p>c) If you have a finite element grid simulation, where each fixed volume cell in space would gain a new value and you need to visualize it via volume rendering or isosurface, here you would want to use a texture object (2D or 3D depending on the dimensionality of your simulation), because when you're casting rays, or even generating streamlines you will almost always be needing to immediately have the neighboring texels cached. And you can avoid doing any copying here, as in the above method you could also directly reference some CUDA texture memory (cudaArray) from OpenGL. You would use these calls to do that:</p> <pre><code>cudaGraphicsGLRegisterImage( &myCudaGraphicsResource, textureNameFromGL, GL_TEXTURE_3D,...) ... cudaGraphicsMapResources(1, myCudaGraphicsResource) cudaGraphicsSubResourceGetMappedArray(&mycudaArray, myCudaGraphicsResource, 0, 0) cudaGraphicsUnMapResources(1, myCudaGraphicsResource) </code></pre> <p>and so this texture data in CUDA can be referenced by mycudaArray while this same memory in OpenGL can referenced by textureNameFromGL.</p> <p>Copying from a buffer into a texture is a bad idea because if you need this data for texture caching you will be doing the additional copy. This was more popular in the earlier versions of CUDA before texture interop was supported</p> <p>You could also use textures in the a) and b) use cases as well. With some hardware it might even work faster, but this is very hardware dependent. Keep in mind also that texture reading also applies minification and magnification filters which is extra work if all you're looking for is an exact value stored in a buffer.</p> <p>For sharing textures resources with CUDA and OpenGL please refer to this sample</p> <p><a href="https://github.com/nvpro-samples/gl_cuda_interop_pingpong_st" rel="nofollow">https://github.com/nvpro-samples/gl_cuda_interop_pingpong_st</a></p> |

Is there any way to capture these signals and with bash (.sh) ignore everyone but one ?</p> <p>Code sent from device:</p> <pre><code>...RUNNING /usr/bin/php /var/www/autosys/python_to_raw.php "class:command;protocol:arctech;model:selflearning;house:13741542;unit:10;group:0;method:turnon;" ...RUNNING /usr/bin/php /var/www/autosys/python_to_raw.php "class:command;protocol:arctech;model:selflearning;house:13741542;unit:10;group:0;method:turnon;" ...RUNNING /usr/bin/php /var/www/autosys/python_to_raw.php "class:command;protocol:arctech;model:selflearning;house:13741542;unit:10;group:0;method:turnon;" ...RUNNING /usr/bin/php /var/www/autosys/python_to_raw.php "class:command;protocol:arctech;model:selflearning;house:13741542;unit:10;group:0;method:turnon;" </code></pre> <p>and my script is:</p> <pre><code>#!/bin/bash if [[ ( "${RAWDATA}" == *13741542* ) && ( "${RAWDATA}" == *turnon* ) ]]; then # Something will be done here, like turn on a lamp, send an email or something else fi </code></pre> <p>(Some explanation to the RAWDATA code can be found here: <a href="http://developer.telldus.com/blog/2012/11/new-ways-to-script-execution-from-signals" rel="nofollow">http://developer.telldus.com/blog/2012/11/new-ways-to-script-execution-from-signals</a>)</p> <p>If i set my bash-script to send an email i get 4 emails, if i set it to update a counter at my local webpage it updates it 4 times. There is no way to controll how many signals the device will send, but can i only capture it once somehow? Maybe some way to "run script on first signal and drop everything else for 5 seconds"</p> |
