"操练身体，益处还少；惟独敬虔，凡事都有益处，因有今生和来生的应许。" (提摩太前书 4:8 和合本) For physical training is of some value, but godliness has value for all things, holding promise for both the present life and the life to come. (1 Timothy 4:8 NIV) Photo by Ines Álvarez Fdez / Unsplash

warning: unsupported value position: absolute; width: 12.9em; transform: translateX(16.27em); ^ and you know, some countries uses decimal point as comma - not point. so scanf function cannot read "12.9em" if we set NUMERIC at that country. Such as French.   // query LC_NUMERIC  char* locale = setlocale(LC_NUMERIC, NULL);  // set LC_NUMERIC  char* locale = "en_US.utf8";  setlocale(LC_NUMERIC, locale);    if LC_NUMERIC was set to "frCA.UTF-8" , 12.9em can't be read as a Decimal. The correct should be like "en_US.utf8" Refer: https://en.wikipedia.org/wiki/Decimal_mark http://man7.org/linux/man-pages/man3/setlocale.3.html

(Hebrews 10:28 NIV) 何况人践踏　神的儿子，将那使他成圣之约的血当作平常，又亵慢施恩的圣灵，你们想，他要受的刑罚该怎样加重呢！ (希伯来书 10:29 和合本) How much more severely do you think someone deserves to be punished who has trampled the Son of God underfoot, who has treated as an unholy thing the blood of the covenant that sanctified them, and who has insulted the Spirit of grace? (Hebrews 10:29 NIV) 因为我们知道谁说："伸冤在我，我必报应"；又说："主要审判他的百姓。" (希伯来书 10:30 和合本) For we know him who said, "It is mine to avenge; I will repay," and again, "The Lord will judge his people."

Refer to: https://www.howtogeek.com/117635/how-to-install-kvm-and-create-virtual-machines-on-ubuntu/ Summary: Determine whether your CPU support hardware virtualization egrep -c '(svm|vmx)' /proc/cpuinfo A 0 indicates that your CPU doesn't support hardware virtualization, while a 1 or more indicates that it does. You still have to enable hardware virtualization support in your computer's BIOS, even if this command returns a 1 or more. Otherwise you will get a warning later on: KVM is not available. This may mean the KVM package is not installed,  or the KVM kernel modules are not loaded.  Your virtual machines may perform poorly.

Refer: https://linux.die.net/man/3/pthread_mutex_init The pthread_mutex_destroy() function shall destroy the mutex object referenced by mutex; the mutex object becomes, in effect, uninitialized. An implementation may cause pthread_mutex_destroy() to set the object referenced by mutex to an invalid value. A destroyed mutex object can be reinitialized using pthread_mutex_init(); the results of otherwise referencing the object after it has been destroyed are undefined. What is the undefined behavior ? Let's us wirte sample codes to verify it. #include <pthread.h> #include <iostream> #include <unistd.h> using namespace std; static pthread_mutex_t foo_mutex; static void * thread1(void *arg) { while(1) { pthread_mutex_lock(&foo_mutex); cout << "thread 1 running" << endl; sleep(2); } } static void * thread2(void *arg) { while(1) { pthread_mutex_lock(&foo_mutex); cout << "thread
