With Bash (source):
# tr includes ABCabc123 and the characters from OWASP's "Password special characters list"
cat /dev/urandom | tr -dc 'A-Za-z0-9!"#$%&\''()*+,-./:;<=>?@[\]^_`{|}~' | head -c 100 ; echo

Why aren't variable-length arrays part of the C++ standard?
... And if you don't know the size beforehand, you will write unsafe code.
C99 VLAs could provide a small benefit of being able to create small arrays without wasting space or calling constructors for unused elements, but they will introduce rather large changes to the type system (you need to be abl...

...数据包被转换为以分号分隔的十进制数字字符串，例如“123；33；0；44”。在 AI2 应用程序中，您可以使用 String.Split 获取字节列表。
对于转换，我使用以下算法：
1) 用分号替换所有逗号
2) 用分号拆分字符串
3) 删除前导和尾随...

What does the C++ standard state the size of int, long type to be?
...one of these de facto standards is legislated by the C standard (ISO/IEC 9899:1999), but all are permitted by it.
And, by definition, sizeof(char) is 1, notwithstanding the test in the Perl configure script.

... A B C D
a 1 4 9 1
b 4 5 0 2

If you want to chain methods, you can add your own mask method and use that one.

In Objective-C why should I check if self = [super init] is not nil?
... that if (self != nil) check is there, for proper operation of your class, 99.99% of the time you actually do need self to be non-nil.
Now, suppose, for whatever reason, [super init] did return nil, basically your check against nil is basically passing the buck up to the caller of your class, where...
What is the “FS”/“GS” register intended for?
...ritten code on 6809 (with and without paged memory), 6502, z80, 68k and 80[123]?86, my perspective is that segmented memory is a horror show and I'm glad it was consigned to the dustbin of history. The use of FS and GS for efficient access of thread_local data is a happy unintended consequence of an...
