Hi All,
I'm trying to get my head around synchronization.
Documentation seems to say that creating a volatile field gives a
memorybarrier.
Great! But when I do a little performance testing Thread.MemoryBarrier is
40 times slower than accessing a volatile int. Also I don't see any
significant difference between the time to increment a volatile int and a

I'm trying to make a thread safe object cache without locking.
The objects are cached by the id of the data dict given in __new__.
Objects are removed from the cache as soon as they are no longer
referenced. The type of the data must be a Python dict (comes from an
external source).
Here's what I've got so far:

Ref Docs: c.l.c FAQ article 12.26 .
www.digitalmars.com sitemap.stdio.fflush
Reading these Docs I understand that fflush does not
summarily destroy or discard the flushed data.
But it is not clear, in the case of fflush(stdin),
where stdin is default C keyboard buffer, what
actually becomes of the data.

Hello,
First let me tell you that I'm very new to C# and learning as I go. I'm
trying to write a client application to communicate with a server (that I
didn't write). Each message from the server is on one line (\r\n at end) and
is formed as - each of
which is seperated by a space. Arguments with spaces in them are enclosed in
quotations.
So, I'm able to open a connection to the server. When I send a message to

Hi people,
I am writing a library that will implement a binary file format.
Well... I'm thinking, as a design, it would be nice to have my library
able to promise to not use more than a certain amount of RAM. I could
have a "SetCacheSize(long NewSize);" function. So as part of that
promise, when required memory exceeds that limit, the extra data is
saved to disk and flushed from RAM.

Does anyone have any input on setting up my CAB application so that the
application is thread safe, and cached appropiately? I read that this
can be managed through Services, and dynamic injection. On the
contrary, I was told that this can be handled using Enterprise Library
cached application block. Last, but not least, i read you can implement
this at the class level, creating immutable classes, and caching them
accordingly. Any...

I've read a bit online seeing that two writes are not safe, which I
understand, but would 1 thread push()'ing and 1 thread pop()'ing be
thread-safe? Basically my situation is the follows:
--Thread 1--
1. Reads TCPIP Buffer
2. Adds Buffer to Queue (q.size() to check queue isn't full, and
q.push_back(...))
3. Signals Reading Thread Event & Goes Back to Wait for More Messages

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
