What is an OS kernel ? How does it differ from an operating system? [closed]
...ialized processes running on top of them. In that case the kernel itself becomes the OS itself.
I think you can draw the line at what the majority of the applications running on top of that OS do require. If most of them require only kernel, the kernel is the OS, if most of them require X Window Sy...

Checkout multiple git repos into same Jenkins workspace
...en you need multiple checkouts in the same physical location maintenance becomes a huge concern. For instance, if you wanted to create a branch build, you would have to clone 4 jobs and then individually change the paths for each one. There are of course plugins to help with this, but it's easier to...
How to initialize a vector in C++ [duplicate]
...
With the new C++ standard (may need special flags to be enabled on your compiler) you can simply do:
std::vector<int> v { 34,23 };
// or
// std::vector<int> v = { 34,23 };
Or even:
std::vector<int> v(2);
v = { 34,23 };
On compilers that don't support this feature (initiali...
What are .NET Assemblies?
...
In more simple terms: A chunk of (precompiled) code that can be executed by the .NET runtime environment. A .NET program consists of one or more assemblies.

Why not infer template parameter from constructor?
my question today is pretty simple: why can't the compiler infer template parameters from class constructors, much as it can do from function parameters? For example, why couldn't the following code be valid:

Best practices for circular shift (rotate) operations in C++
...with some more details about what asm gcc/clang produce for x86.
The most compiler-friendly way to express a rotate in C and C++ that avoids any Undefined Behaviour seems to be John Regehr's implementation. I've adapted it to rotate by the width of the type (using fixed-width types like uint32_t)....
'Static readonly' vs. 'const'
...a little unusual; public static properties (with only a get) would be more common (perhaps backed by a private static readonly field).
const values are burned directly into the call-site; this is double edged:
it is useless if the value is fetched at runtime, perhaps from config
if you change the...
What are the undocumented features and limitations of the Windows FINDSTR command?
The Windows FINDSTR command is horribly documented. There is very basic command line help available through FINDSTR /? , or HELP FINDSTR , but it is woefully inadequate. There is a wee bit more documentation online at https://docs.microsoft.com/en-us/windows-server/administration/windows-commands...
Why doesn't await on Task.WhenAll throw an AggregateException?
...n When Exceptions Happen)
...When you use await, the code generated by the compiler unwraps the
AggregateException and throws the underlying exception. By leveraging
await, you avoid the extra work to handle the AggregateException type
