mySQL win32 (4.0.22)
I am using mySQL Control Admin and seeing a lockup on a thread specific to a
like query.
select * from table1 where field1 like 'http://h%' limit 100
This request will sit (thread) forever and never return any records. (status
: sending...)
However : select * from table1 where field1 like 'http://h%' limit 100

Got a site where we are still running the front end and back end on an
older machine under access 97 plus a new machine using XP as the front
end.
Only installed the XP version yesterday.
Client is reporting a one off complete lockup of the 97 machine this
morning (sounds like it happened when the XP machine looked at it).
They are back up and running happily at this moment.

We are evaluating some old code that was written as part of our math
library.
This code uses some optimizations that I'm not sure are necessary or
safe, but is a source of debate between my coworkers.
Method 1 includes a temporary storage varriable at class scope.
Method 2 includes a temporary storage varriable at method scope.
Method 3 includes a temporary static storage varriable at method scope.
Are any of the methods better than...

Below are 2 files that isolate the problem. Note, both programs hang
(stop responding) with hyper-threading turned on (a BIOS setting), but
work as expected with hyper-threading turned off.
Note, the Windows task manager shows 2 CPUs on the Performance tab with
hyper-threading is turned on.
Both Python 2.3.5 and 2.4.3 (downloaded from python.org) have this
problem.
The operating system is MS Windows XP Professional.

I have a form, and from the form when a user clicks a button, it instantiates
control that will be doing a lot of logic. I am trying to use
System.Threading.ThreadPool.QueueUserWorkItem to spawn a background thread
off the pool. I stepped through the logic, and everything seems to go
through fine when the control is initialized, and my main form continues to
work correctly. The only issue is that the control seems to not render
properly...

Obviously wrapping a critical section around access to some set of
shared state variables flushes any cached data, etc so that the threads
involved don't see a stale copy. What I was wondering is *what*
exactly gets flushed. Does the compiler some how determine the data
that is accessible from that thread, and flush just that set? (Seems
unlikely to me). Is it all data cached in registers etc? Or am I
overthinking this and instead...

Because C# has no native SSH class, I am using SharpSSH. Sometimes, for
reasons I do not know, a Connect call will totally lock up the thread and
never return. I am sure it has something to do with weirdness going on with
the server I am talking to. Anyhow, this locked up state happens once in a
while (maybe once per day) and I can't figure out how to deal with the locked
up thread.
If I issue a Thread.Abort() the exception never...

Hi all,
Recently I had a new coworker. There is some dispute between us.
The last company he worked for has a special networking programming
model. They split the business logic into different modules, and have
a dedicated thread for the each module. Modules exchanged info
through a in-memory message queue.
In my opinion, such a model means very complicated asynchronous

Hello everyone.
Recently I stumbled upon an interesting problem related to thread-parallel
programming in C (and similarily C++). As an example assume a simple "buffer"
array of size 8, e.g. with static lifetime and exteral linkage. One thread fills
the buffer structure, and the other in some way evaluates its contents, e.g.
do {
synchronize_with_other_thread();
for (int i=0;i<8;++i) {

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
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...
