What you are seeing is a marketing stunt. Since non-technical people don’t know the difference between Metric Meg, Gig, etc. against the binary Meg, Gig, etc. marketers for storage will use the Metric calculation, thus 1000 Bytes == 1 KiloByte.

When user space applications call malloc(), that call isn’t implemented in the kernel. Instead, it’s a library call (implemented glibc or similar). The short version is that the malloc implementation in glibc either obtains memory from the brk()/sbrk() system call or anonymous memory via mmap(). This gives glibc a big contiguous (regarding virtual memory addresses) … Read more
We have two options. Look at Preferences->Locations->”Custom Paths” in Xcode’s preference. A path added here will be a variable which you can add to “Header Search Paths” in project build settings as “$cppheaders”, if you saved the custom path with that name. https://help.apple.com/xcode/mac/11.4/#/deva52afe8a4 Set HEADER_SEARCH_PATHS parameter in build settings on project info. I added “${SRCROOT}” … Read more

QProcess process; process.start(“gedit”, QStringList() << docPath); the same as above QProcess process; process.start(“gedit”, QStringList() << “/home/oDx/Documents/a.txt”); Also, read this.
exec — Execute an external program system — Execute an external program and display the output shell_exec — Execute command via shell and return the complete output as a string so if you don’t need the output, I would go with exec. Further details: http://php.net/manual/en/function.exec.php http://php.net/manual/en/function.system.php http://php.net/shell_exec
Both Debian and Ubuntu ship with pam_umask. This allows you to configure umask in /etc/login.defs and have them apply system-wide, regardless of how a user logs in. To enable it, you may need to add a line to /etc/pam.d/common-session reading session optional pam_umask.so or it may already be enabled. Then edit /etc/login.defs and change the … Read more
Use intern=TRUE: a <- system(“ls “, intern = TRUE)
Pass the arguments before the -jar. If you pass them after the jar file they are interpreted as command line parameters and passed to the String[] args in main. Like, java -Denviroment=dev -jar myjar.jar
Use the collapse argument to paste: paste(a,collapse=” “) [1] “aa bb cc”
