clock

问题 I have a Nvidia Jetson tx1 board and want to change the gpu rate by writing in the following file: sudo echo 691200000 > /sys/kernel/debug/clock/override.gbus/rate sudo echo 1 > /sys/kernel/debug/clock/override.gbus/state However I get greeted with a Permission denied I know the commands from the following script https://github.com/dusty-nv/jetson-scripts/blob/master/jetson_max_l4t.sh which was proposed by an nvidia-employee. However I do not want to max out the gpu clock frequency, I want to

问题 I am writing an alarm clock app. Please correct me if I am wrong: On both events (lock & home button in iOS 4.x) the applicationWillResignActive: method is called. When locked my app can keep on running (forever if DeepSleepPreventer.h is used) to check if the alarm should go off. When home is pressed it has to stop working at some time (apart from some basic background calculations). So in this case I have to set a local UILocalNotification to trigger the alarm. So my question: How to

问题 I'm writing an app that sets an alarm, and here's the relevant code that's causing a force close: Intent i = new Intent(AlarmClock.ACTION_SET_ALARM); i.putExtra(AlarmClock.EXTRA_HOUR, hours); i.putExtra(AlarmClock.EXTRA_MINUTES, minutes); i.putExtra(AlarmClock.EXTRA_SKIP_UI, true); startActivity(i); The startActivity(i) is causing the force close. I tried catching ActivityNotFoundException and displaying a Toast, but the force close is still happening. I'm really new to Android programming,

问题 I have two programs written in .NET that communicate with acquisition hardware via USB. One device is asynchronous, but it tells me down to the microsecond when a data point was recorded. The other one is synchronous, that is, I know when each data point was recorded. I have .NET programs to interface with these. Until now, I have used DateTime.Now to establish when acquisition started, then I use the millisecond/microsecond time reported by the asynchronous device and the sample number from

问题 I searched the topic for several days, but finally confused. The idea is to create own alarm app with some special tricks. Firstly, I need clock hands. For creating custom clock, I used own class, which extends View. Hour and minute hands are PNG images. They should be located in the center of the screen, but they dont. Actually, I can't even see them. And that is the question. Here is the Clock class import android.annotation.SuppressLint; import android.content.Context; import android

问题 Hopefully this is an easy one because I've been trying all sorts of different ways to get rid of this. I am making an android app which incorporates a clock animation. I've got everything working really well except one very annoying thing. I have a second hand on the clock and I'm using the following code to rotate it around a the second hand center point. As you'll probably notice I'm trying to make this look like an analogue second hand so it sweeps instead of just ticking. public float

问题 I'm quite new to JavaScript and I have trouble working with etInterval() . I'm creating an analogue clock as an exercise. I have a function setTime() that gets and displays the time by rotating the arrows accordingly. I want to execute this function again and again. Here is my code : $(document).ready(function(){ function setTime(){ var d = new Date(); var hour = d.getHours(); var minute = d.getMinutes(); var hourRotation = hour * 30 + (minute / 2); var minuteRotation = minute * 6; $("#small"

问题 Given a start date, and a number of days, I need to display the end date = start date + number of days. So I did something like this: var endDate=new Date(startDate.getTime()+ONE_DAY); Everything works fine, except that for 25 and 26 October gives one day less. Ex.: 2014-01-01 + 2 days = 2014-01-03 2014-10-25 + 2 days = 2014-10-26 (here is the case I need to treat). This difference appear because of the clock going back 1 hour. Practically 2014-10-27 00:00:00 becomes 2014-10-26 23:00:00 . A

问题 I try to put style in a p:clock element with class attribute but I receive the following message: java.lang.IllegalArgumentException: Setter not found for property class. That's another way to define style to a p:clock element? XHTML: <p:clock pattern="HH:mm" class="clock"/> CSS: .clock { border-radius: 0px !important; } 回答1: Never use class . For many components you'd use styleClass instead, but here you have to do it like this: <p:clock pattern="HH:mm"/> .ui-clock{ border-radius: 0px

问题 I wish to calculate the time passed in milliseconds from a specific time in Java. The classic way it to use System.currentTimeMillis(); for the starting time, and then use this again with the previous one to get the elapsed time. I wish to do something similar to this, but NOT rely on the system time for this. If I rely on the system time, the user of the program could manipulate the system clock to hack the program. I have tried using code similar to the following: int elapsed = 0; while
