WEBoggle needs a new game board every three minutes. Boards take an
unpredictable (much less than 3min, but non-trivial) amount of time to
generate. The system is driven by web requests, and I don't want the
request that happens to trigger the need for the new board to have to
pay the time cost of generating it.
I set up a producer thread that does nothing but generate boards and put
them into a length-two Queue (blocking). At the rate...

I have one process that will be multi-threaded. The parent (A) will
sit and deal with TCP/IP issues, and feed data to its child process
(B) via shared memory. I need assistance in finding a good example of
(B) pausing (not in a busy-wait loop) until it gets a signal from (A)
that data is ready.
That the child process (B) will then have a shared memory segment with
a second running process (C), where (B) will be the producer for (C),

Hello,
I have an application that essentially consists of two threads doing
their things. One thread is a producer, and pushes bytes (of a struct)
into a pipe, and another is a consumer that simply checks the pipe at
regular intervals reads out the bytes. If the consumer extracts bytes
and sees that it's not enough to recast to the struct, it caches it and
waits for more bytes in the pipe.
My question is: Do I still need to maintain...

I am developing an application that has several multi threaded tasks where
one thread is doing IO and another thread is grabbing data from the first
thread to process it further.
I've been noticing that every once in a while my program simply hangs- it is
rare but it is annoying. I am worried it may be a synchronization issue
involving my producer/consumer threads.
I basically go like this:

Hi all,
I am trying to develop a Producer thread that listens for UDP packets on a
socket and store then in an ArrayList.
The consumer should read data from list and block when no element is in
list.
When producer inserts a message in list, it should make the consumer aware
of the item and consumer should process the item as soon as it is available.

Hi,
I'm trying to implement the Producer-Consumer-Problem in C#.
Below is my code. The problem is, that the buffer always contains only one
element...it seems
that the Thread.Sleep() in the producer and in the consumers make the whole
app sleep
instead of only making the current thread sleep.
Maybe someone can help?

It seems to me that the MSDN code for synchronizing a producer and consumer
thread at http://msdn2.microsoft.com/en-us/library/yy12yx1f.aspx is
completely wrong. There is no reason to assume that each call to
NewItemEvent.Set() will release a consumer thread (as explicitly mentioned in
the AutoResetEven documentation), which means that the consumer threads won't
necessarily know that there are items on the queue.
Is this correct?

I'd like some feedback on a solution to a variant of the producer-
consumer problem. My first few attempts turned out to deadlock
occasionally; this one seems to be deadlock-free so far but I can't
tell if it's provably correct, and if so, whether it can be
simplified.
The generic producer-consumer situation with unlimited buffer capacity
is illustrated at http://docs.python.org/lib/condition-objects.html.
That approach assumes that the...

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
