3,488,058 | 0 | <p><Edit> Although one object can access private properties of all objects of the same class, you cannot access protected methods of an object from other class even if the protected method is defined in a common super class.</p> <p>So while this code compiles:</p> <pre><code>public class Test { private int x; private void change(Test test) { test.x = test.x + 1; } public static void main() { Test test1 = new Test(); Test test2 = new Test(); test1.change(test2); } } </code></pre> <p>The following code will not compile:</p> <pre><code>public class Test2 { public static void main() { Test1 test1 = new Test1(); test1.clone(); // The method clone() from the type Object is not visible } } </code></pre> <p></Edit></p> <p>Being able to call <code>toString()</code>, <code>equals(Object)</code>, <code>hashCode()</code> and <code>getClass() on all objects makes things a lot easier.</p> <p><code>clone()</code> and <code>finalize()</code> are protected. So in order to be able to call them from the outside the subclass has to increase the visibility. And that is obviously a design decision.</p> <p>To be honest, i have no idea why Sun decided that all object are "locks" and have <code>notify()</code>, <code>notifyAll()</code>, <code>wait(long)</code>, wait(long, int)</code>. From my point of view those method should not be in Object at all but in a specialized Lock-class. But I guess there was a good reason to have them there in the very early days and it cannot be changed nowadays without breaking compatibility.</p> |

'.php'; $cache[$language][$file] = $lang; } return $lang; // return requested data, which is now definitely cached } </code></pre> <p>And to use it, you would do:</p> <pre><code>$lang = $this->lang('global', 'en'); </code></pre> <p>Dumping raw variables into the global scope like this is not always the best idea, but depending on the circumstances (small projects) it might be OK.</p> |

This answer is a bonus, an alternate avenue to accomplish the goal of calculating and applying elapsed time.</p> <p>Doing this kind of date-time work is much easier if using either of these libraries:</p> <ul> <li><a href="http://www.joda.org/joda-time/" rel="nofollow">Joda-Time</a></li> <li><a href="http://docs.oracle.com/javase/8/docs/api/java/time/package-summary.html" rel="nofollow">java.time package</a><br/>(built into Java 8, inspired by Joda-Time, defined by <a href="https://jcp.org/en/jsr/detail?id=310" rel="nofollow">JSR 310</a>)</li> </ul> <p>The old date-time classes (java.util.Date, .Calendar, java.text.SimpleDateFormat) bundled with Java are notoriously troublesome, confusing, and flawed. Avoid them. If required you can convert to-and-fro with either library listed above.</p> <h1>Joda-Time</h1> <p>The code example below is using Joda-Time 2.5.</p> <h2>Elapsed Time</h2> <p>You can count elapsed time in either of two ways: </p> <ul> <li><strong>Calendar</strong> style<br/>Number of months, weeks, days, and such.</li> <li><strong>Stopwatch</strong> style<br/>Total number of milliseconds, as if measured with a running <a href="http://en.wikipedia.org/wiki/Stopwatch" rel="nofollow">stopwatch</a>.</li> </ul> <p>These two ways to measure elapsed time may give different results! This code example shows both.</p> <h2>Time Zone</h2> <p>Unlike j.u.Date, a <code>DateTime</code> object in Joda-Time actually knows its own assigned time zone. That is crucial if you count elapsed time by the calendar style (months, days, and so on). Note how this example uses Montréal, Québec time zone (arbitrarily chosen).</p> <h2>Example Code</h2> <pre><code>// Simulate inputs, a trio of java.util.Date objects. java.util.Date dateStart = new DateTime( 2014 , 1 , 2 , 0 , 0 , 0 , DateTimeZone.UTC ).toDate(); java.util.Date dateStop = new DateTime( 2014 , 3 , 2 , 0 , 0 , 0 , DateTimeZone.UTC ).toDate(); java.util.Date dateTarget = new DateTime( 2014 , 7 , 1 , 0 , 0 , 0 , DateTimeZone.UTC ).toDate(); // Convert inputs to Joda-Time DateTimeZone timeZone = DateTimeZone.forID( "America/Montreal" ); // Or DateTimeZone.UTC. DateTime start = new DateTime( dateStart , timeZone ); DateTime stop = new DateTime( dateStop , timeZone ); DateTime target = new DateTime( dateTarget , timeZone ); // Determine elapsed time in three fashions: (a) pair of points on timeline, (b) An amount of weeks, days, hours, and such, and (c) actual milliseconds. Interval interval = new Interval( start , stop ); Period period = interval.toPeriod(); Duration duration = interval.toDuration(); // Add elapsed time to target date-time. Show results of adding either period or duration. DateTime laterByPeriod = target.plus( period ); DateTime laterByDuration = target.plus( duration ); </code></pre> <p>Dump to console.</p> <pre><code>System.out.println( "dateStart: " + dateStart ); // BEWARE: j.u.Date objects are in UTC by definition, but "toString" method applies the JVM's current default time zone.

17,429,964 | 0 | <p>There is never a guarantee that you will not get stuck in a local optimum, sadly. Unless you can prove certain properties about the function you are trying to optimize, local optima exist and hill-climbing methods will fall prey to them. (And typically, if you can prove the things you need to prove, you can also select a better tool than a neural network.)</p> <p>One classic technique is to gradually reduce the learning rate, then increase it and slowly draw it down, again, several times. Raising the learning rate reduces the stability of the algorithm, but gives the algorithm the ability to jump out of a local optimum. This is closely related to simulated annealing.</p> <p>I am surprised that Google has not helped you, here, as this is a topic with many published papers: Try terms like, "local minima" and "local minima problem" in conjunction with neural networks and backpropagation. You should see many references to improved backprop methods. </p> |

Maybe it would be useful that I'm in tmp dir and I can not leave it at this moment.</p> <p>I've already study Netgem SDK looking for information and I found nothing, the same result after searching in google, so that's why I came looking for help here.</p> |

I have used the animation-play-state: paused, but it does not work. I can use the jquery function, but I really want to try and get this to work in css only. Am I screwing up on the parent child relation? Or is this timing sequence not supported or messing with the pause issue? Perhaps I need to do a hover type pause and build a new div for that? I know I am making a simple mistake.</p> |

22,771,957 | 1 | python subprocess sends backslash before a quote <p>I have a string, which is a framed command that should be executed by in command line</p> <p>cmdToExecute = "TRAPTOOL -a STRING "ABC" -o STRING 'XYZ'"</p> <p>I am considering the string to have the entire command that should be triggered from command prompt. If you take a closer look at the string cmdToExecute, you can see the option o with value XYZ enclosed in SINGLE QUOTE. There is a reason that this needs to be given in single quote orelse my tool TRAPTOOL will not be able to process the command.</p> <p>I am using subprocess.Popen to execute the entire command. Before executing my command in a shell, I am printing the content</p> <pre><code>print "Cmd to be exectued: %r" % cmdToExecute myProcess = subprocess.Popen(cmdToExecute, stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=False) (stdOut, stdErr) = myProcess.communicate() </code></pre> <p>The output of the above command is, Cmd to be executed: TRAPTOOL -a STRING "ABC" -o \'XYZ\'.</p> <p>You can see that the output shows a BACKWARD SLASH added automatically while printing. Actually, the \ is not there in the string, which I tested using a regex. But, when the script is run on my box, the TRAPTOOL truncates the part of the string XYZ on the receiving server. I manually copy pasted the print output and tried sending it, I saw the same error on the receiving server. However, when I removed the backward slash, it sent the trap without any truncation.</p> <ol> <li>Can anyone say why this happens?</li> <li>Is there anyway where we can see what command is actually executed in subprocess.Popen?</li> <li>Is there any other way I can execute my command other that subprocess.Popen that might solve this problem?</li> </ol> |

28,686,099 | 0 | Why NOP/few extra lines of code/optimization of pointer aliasing helps? [Fujitsu MB90F543 MCU C code] <p>I am trying to fix an bug found in a mature program for Fujitsu MB90F543. The program works for nearly 10 years so far, but it was discovered, that under some special circumstances it fails to do two things at it's very beginning. One of them is crucial.</p> <p>After low and high level initialization (ports, pins, peripherials, IRQ handlers) configuration data is read over SPI from EEPROM and status LEDs are turned on for a moment (to turn them a data is send over SPI to a LED driver). When those special circumstances occur first and only first function invoking just a few EEPROM reads fails and additionally a few of the LEDs that should, don't turn on.</p> <p>The program is written in C and compiled using Softune v30L32. Surprisingly it is sufficient to add single __asm(" NOP ") in low level hardware init to make the program work as expected under mentioned circumstances. It is sufficient to turn off 'Control optimization of pointer aliasing' in Optimization settings. Adding just a few lines of code in various places helps too.</p> <p>I have compared (DIFFed) ASM listings of compiled program for a version with and without __asm(" NOP ") and with both aforementioned optimizer settings and they all look just fine.</p> <p>The only warning Softune compiler has been printing for years during compilation is as follows:</p> <blockquote> <p>*** W1372L: The section is placed outside the RAM area or the I/O area (IOXTND)</p> </blockquote> <p>I do realize it's rather general question, but maybe someone who has a bigger picture will be able to point out possible cause. </p> <p>Have you got an idea what may cause such a weird behaviour? How to locate the bug and fix it?</p> <p>During the initialization a few long (about 20ms) delay loops are used. They don't help although they were increased from about 2ms, yet single NOP in any line of the hardware initialization function and even before or after the function helps.</p> <p>Both the wait loops works. I have checked it using an oscilloscope. (I have added LED turn on before and off after).</p> <p>I have checked timming hypothesis by slowing down SPI clock from 1MHz to 500kHz. It does not change anything. Slowing down to 250kHz makes watchdog resets, as some parts of the code execute too long (>25ms).</p> <p>One more thing. I have observed that adding local variables in any source file sometimes makes the problem disappear or reappear. The same concerns initializing uninitialized local variables. Adding a few extra lines of a code in any of the files helps or reveals the problem.</p> <pre><code>void main(void) { watchdog_init(); // waiting for power supply to stabilize wait; // about 45ms hardware_init(); clear_watchdog(); application_init(); clear_watchdog(); wait; // about 20ms test_LED(); {...} } void hardware_init (void) { __asm("NOP"); // how it comes it helps? - it may be in any line of the function io_init(); // ports initialization clk_init(); timer_init(); adc_init(); spi_init(); LED_init(); spi_start(); key_driver_init(); can_init(); irq_init(); // set IRQ priorities and global IRQ enable } </code></pre> |
