I'm hoping my post here doesn't fall into the 'hard to say' category,
nonetheless I've been advised that multiple uses of accessor/mutator
(get/set) member functions can be viewed as a 'design flaw'. In that
regard I'm trying to create an 'example' class that's an alternative
to the accessor/mutator approach. To further describe the problem
consider the class BAR (below) which has a member data in_use that FOO
needs visibility into. ...

I've got an unpacker that unpacks a 32 bit word into 3-10 bits samples.
Bits 0 and 1 are dont cares. For the purposes of perfoming an FFT and
an inverse FFT, I cast the 10 bit values into doubles. I'm told:
"floats and doubles have bits for mantissa and exponent. (I knew that).
If you are subtract bits that partly belong to mantissa and partly
belong to exponent, that hardly makes sense. Anyway, looking on bits
only, a float has 32...

Dear all,
It would be nice if the Design advisor was not outputing all "unused
indexes" of the whole database (10000 tables at least), when the workload is
only using 4 tables.
Why not limiting these "unused indexes" to the 4 tables in the workload ?
Best regards,

Does anyone have experience with running the DB2 Design Advisor on huge
workloads? I have a workload for a single day for some 132'000
statements in a file. Will the advisor handle this or should I take a
sample?
Thanks,

Dear all,
After FP8 apply on a DB2 UDB multi-partition instance, the design advisor's
MQT function is not selectable. From the DB2 Information Center (FP7), there
is nothing that suggests that MQTs should not work in multi-partition. Have
you encountered this problem (I have tested and got the problem on both
Windows and Linux) ?

Hello,
I am using DB2 UDB v.8.2, with TPC-H 1GB database.

the design advisor does not recommend anything.

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...

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,...

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...
