A little annoyed one day that I couldn't use the statefulness of
generators as "resumable functions", I came across Hettinger's PEP 288
(http://www.python.org/peps/pep-0288.html, still listed as open, even
though it's at least a year old and Guido doesn't seem very hot on the
idea). I'm not too sure of its ideas on raising exceptions in
generators from outside (although it looks like it might be convenient
in some cases), but being able...

Hello,
- Is any body aware of a random workload/query generator such as the
TPC-H query generator (QGEN) ? I am looking for a query generator that
takes a schema as an input, and produces several queries.
I need it mainly for performance evaluation. the generator I am looking
for should produce SELECT queries, including joins, and not only INSERT
INTO, DELETE, UPDATE queries such as the "SqlQueryGenerator" at...

Does anyone have experience with running the DB2 Design Advisor on huge

sample?

Hello All,
Is it possible to create multiple random numbers in a query where
there are numerous records?
I've created a custom function. When I use it in a query it creates
the same random number for ALL the records. It appears the function is
only getting called once, therefore only one random number is being
generated for all the records. I want a different random number for
each record. Is this possible, or do I have to do it all...

Hello All,
In an 'Update' query can you use user-defined functions in the 'Update
To' for the query? Either no or I'm missing something. See the
additional info below.
If I run a query as a select query it runs fine. The select query is as

I am a newbie in ASP.NET (using VB.NET) & work on Windows 2000 Professional.
I find that the client browser just doesn't play any role other than rendering the page in HTML & the server does all the work. Even the various HTML/Web controls are validated by the server. So ASP.NET relying so much on the server to do even a small task - doesn't this put extra load on the server & in the process,slow down the retrieval time of ASPX pages? A Form...

Over the past few years I have consulted on six large projects that all
independently arrived at the same moronic design desision: The use of
SQL query classes.
No, I don't mean a class hierararchy like:
SQL Query
UpdateQuery
SelectQuery
Where you hide the details of the underlying database API. (Along the
lines of what Rogue Wave does.)

I've been fooling around with large numbers for a little while, and seeing how slow my laptop is calculating prime numbers above 10^8, have been wishing I had a dedicated machine to crunch numbers... If I have the concept somewhat right, supercomputers essentially are clusters of CPUs on purpose-made motherboards all linked together to share workload. Obviously such a machine is out of the question, but I do know that there are dual-processor...

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...

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...

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...
