For a class, MyClass, there are two ways to instantiate an object:
1. MyClass *MC = new MyClass();
2. MyClass MC;
In general, when should you have to use 1 and when 2? What're
advantages/disadvantages of using either?
Thanks!

We've had a very large A97 app running fine for the last seven years.
I've just converted to SQL Server backend, which is being tested, but
meanwhile the JET based version, running under terminal server, has
suddenly started running very slowly. The network engineer has thrown
up his hands and said "It's Access 97". I've checked out lots of
things including the Oplocks setting and other stuff from this NG, and
I think I've done everything...

Hi,
I wrote the code to test how CacheItemPriority.NotRemovable works:
Cache.Insert("Time", DateTime.Now,
new System.Web.Caching.CacheDependency(Server.MapPath("Test.txt")),
System.Web.Caching.Cache.NoAbsoluteExpiration,
System.Web.Caching.Cache.NoSlidingExpiration,
CacheItemPriority.NotRemovable, null);
When then Test.txt is changed, the cache item "Time" is unavailable,

Hi
I just have one server that runs Apache, MySQL, PHP. It handles
requests fine and never had problems. When should I think about a small
step into scaling? By maybe having an independent MySQL server? How
many QPS (Querys Per second) (approx) on the MySQL DB will it be
optimal for me to have MySQL on a seperate maybe more powerful machine?
The current server has 1GB Ram and intel duo core processors..
I know the question is a bit...

FAQ Topic - When should I use eval?
-----------------------------------------------------------------------
The ` eval() ` function should _only_ be used when it is necessary to
evaluate a string supplied or composed at run-time; the string
can be anything from a simple (but unpredictable) expression such
as 12*2.54 to a substantial piece of javascript code.

I have run into a situation that if a page/tab that uses the Ajax toolkit
(using .net version 3.5) is closed before the Ajax enable controls complete
loading, then IE locks up. Does it in both IE7 and IE8. There is no issue
when the controls are allowed to complete loading.
Can you please tell me the best practice that handles this?
Thanks.

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
Here is the code in...

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...
