Wake Windows PC from sleep in Python 2.7

阅读更多关于 Wake Windows PC from sleep in Python 2.7

问题 I have a script that will put the system to sleep in the middle of it. Is there any way to make that script wake the system up and then continue running? I have read many round-about ways of doing so by Wake on LAN or using Task Scheduler. I am looking for something that would wake it up after a set period of time or after a specific piece of my script is finished. I will need to this to work for Windows 7, 8.1, and 10. Anyone know of a way to wake from sleep while still running a script? 回答1

问题 i start an activity from a BroadcastReceiver, which is triggered by an alaram (RTC_WAKEUP type). in onCreate of that activity i add these flags getWindow().addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD | WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED | WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON | WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON ); problem is that sometimes (approximately 10% cases) the screen does not turn on. the alarm is correctly triggered (i here the sound

题目可以知道是关于PHP序列化的问题。 class xctf { //定义类xctf public $flag = '111' ; //flag赋值为111 public function __wakeup ( ) { //关于魔术变量_wakeup() exit ( 'bad requests' ) ; } ? code = 序列化后的字符串绕过_wakeup()： _wakeup()执行漏洞：一个字符串或对象被序列化后，如果其属性被修改，则不会执行_wakeup()函数，这是一个绕过点。改变序列化后的属性的个数: <? class xctf { public $flag = '111' ; } $a = new xctf ( ) ; echo serialize ( $a ) ; ?> 将源代码的"?code="加上O:4:“xctf”:1:{s:4:“flag”;s:3:“111”;} 添加到url内；关于PHP反序列化漏洞可以参考： https://www.jianshu.com/p/1d2c65601d2a 来源： CSDN 作者： LEO__Z 链接： https://blog.csdn.net/zouchengzhi1021/article/details/104277188

Does OnNavigatedTo get called when you turn on the screen and the app comes to life?

问题 I'm dealing with a strange situation I want to debug in my Windows Phone 8.1 app, and I'm not sure in which moments OnNavigatedTo is called. Obviously, it gets called (and I've checked tracing it with the debugger) when you navigate to the view normally. My doubt arises in other point I want to check, let's call it "You wake up your application and the screen was shut off". My question is: When you turn on the screen, and you swype the screen protector away, is "OnNavigatedTo" function called

问题 I'm running a long python script in the windows command line with several prints throughout my code to keep track of progress. Right before certain prints, the python code stops running and CPU Usage just drops to zero. I can "wake up" python by hitting random keys on the keyboard with the command line window as the active window. Using Task Manager, I can see that the CPU usage jumps, the print line processes ("Process took 219 seconds") and then the script gets going again. Why do I have to

阅读更多关于 What to make of an “impossible” stack trace after a crash?

问题 My program appears to be suffering from a very hard-to-reproduce bug: Once in a blue moon, when a user puts his Mac to sleep and later on wakes it back up again, one of my program's child processes will crash immediately after the Mac wakes up. When this happens Apple's crash-reporter mechanism reliably reports a stack trace like this one: Thread 0 Crashed:: Dispatch queue: com.apple.main-thread 0 libsystem_kernel.dylib 0x967f9a6a __pthread_kill + 10 1 libsystem_c.dylib 0x9003dacf pthread

问题 I have a problem with acquiring a WakeLock. It seems not to work. I am trying to acquire a FULL_WAKE_LOCK but neither the display gets enabled nor is my app able to perform tasks. I am using the following permission: android.permission.WAKE_LOCK My acquire code looks like this: PowerManager pm = (PowerManager) getBaseContext().getSystemService(Context.POWER_SERVICE); wl = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK|PowerManager.ACQUIRE_CAUSES_WAKEUP, "My Tag"); wl.acquire(); What am i doing

how to wakeup android phone from sleep?

问题 How to wakeup android phone from sleep (suspend to mem) programmably? I don't want to acquire any wakelock, which means the phone goes into "real" sleep with the cpu disabled. I guess I can use some kind of RTC (real time clock) mechanism? Does anyone have any examples? Thanks. 回答1: In order to let the Activity wake up the device and not require a password/swipe, you only need to add a few flags. To get that, include to your code: this.getWindow().setFlags(WindowManager.LayoutParams.FLAG

Selector.wakeup() and “happens-before” relationship

问题 Im writing yet another NIO server. There is a selector thread that performs reading, processing (for the most cases) and writing (pseudo-code below, not real Java): while (true) { select(); for (key : keys) { if (isReading(key)) { data = read(key.channel()); result = process(data); key.interestOps(OP_WRITE); } if (isWriting(key)) { key.channel().write(result); } } } The processing for the most cases is trivial, so should be fine. However there are (rare) cases, when processing is time
