When examining an Android phone, we have to overcome some barriers first so that we could extract data from it without fail. Usually the scenario is that Suspect's phone got pattern lock / password lock and you are not sure if USB Debug mode is ON or…

p { margin-bottom: 0.1in; line-height: 120% } 一.一开始我是按照网友所说的 : rm -f ~/.gnome2/keyrings/login.keyring 删除秘钥文件, 按照网友的解决办法,这步之后,会打开新的程序会提示输入新的密码.但是重新打开谷歌浏览器,还是提示unlocking, 然后我开始排除问题所在,首先  cd ~/.gnome2/ 里面是空的了,有两种可能一种是我删掉了,一种就是本来就是空的,但keyrings文件夹应该还在才对.猜…

LOCK TABLES对事务不安全,并且在试图锁定表之前隐式提交任何活动事务. UNLOCK TABLES只有在LOCK TABLES已经获取到表锁时,会隐式提交任何活动事务.对于下面的一组语句,UNLOCK TABLES释放了全局读锁,但是因为没有表锁,不会提交事务. FLUSH TABLES WITH READ LOCK; START TRANSACTION; SELECT ... ; UNLOCK TABLES; 开始一个事务(例如,START TRANSACTION)隐式地提交任何当前事…

Given an Android 3x3 key lock screen and two integers m and n, where 1 ≤ m ≤ n ≤ 9, count the total number of unlock patterns of the Android lock screen, which consist of minimum of m keys and maximum n keys. Rules for a valid pattern: Each pattern m…

前篇博客LZ已经分析了ReentrantLock的lock()实现过程,我们了解到lock实现机制有公平锁和非公平锁,两者的主要区别在于公平锁要按照CLH队列等待获取锁,而非公平锁无视CLH队列直接获取锁.但是对于unlock()而已,它是不分为公平锁和非公平锁的. public void unlock() { sync.release(1); } public final boolean release(int arg) { if (tryRelease(arg)) { Node h = he…

我们都知道,当一条记录进入审批流程以后会自动加锁,apex提供Approval类的lock和unlock方法可以让我们使用代码对记录进行加锁和解锁. 项目中遇到一个需求,需要当某种情况下对记录进行先解锁,然后update相关数据,然后再加锁.此种方式不影响审批流程. 主要大概代码如下所示 if(Approval.isLocked(xxApproval)) { Approval.UnlockResult ur = Approval.unlock(xxApproval.Id); if (ur.isS…
