I know the answer to this is going to be "It depends . . .", but I want
to get my mind right. In Fowler's *Refactoring* I read: "Older
languages carried an overhead in subroutine calls, which deterred
people from small methods" (followed by the basic "Extract Method"
advice). In Skip Montanaro's "Python Performance Tips"
(http://manatee.mojam.com/~skip/python/fastpython.html) I read: ". . .

mysql v4.0.16:
I had been using mysql with innodb and thought that was fine, until i used
it for something requiring a few - perhaps slightly involved - joins, and
have now seen the performance become totally unacceptable.
I have a query that takes over 35 seconds using mysql and innodb, for
reasons that are completely a mystery to me, in a result set consisting of
only a handful of items.

Hi all,
I have done a lot of experimentations using several
"or" predicates within an sql select statements on mysql.
My only conclusion so far is that whatever syntax or order
I use it is always slower than doing seperate
sql statements (one for each or) and programaticaly
adding them to a vector.

Hello,
I have a client (customer) who asked the question : "Why would I buy and
use UDB, when MySql is free?"
I had to say I was stunned. I have no experience with MySql, so I was
left sort of stammering and sputtering, and managed to pull out something
I heard a couple of years back - that there was no real transaction
safety in MySql. In flight transactions could be lost.

At this moment I use MsAccess and i can build about every databound
application i want. Who knows about a serious open source alternative?
Because Windows will be a client platform for some time, i prefer a
solution that (also) supports Windows.
On the net I found a number of products that i looked at, but none of
them gave me the impression of a serious candidate at this moment
(KNoda, Gnome DB Manager, InterBase...).

Hi!
My company make several flash-based games, and I use php to communicate with
mysql to provide highscore-lists.
My problem is this:
When I save a player's score in the mysql-table, I want to find which place
the player got with his score (today). To get this I have tried two
different solutions, which both works, but are very ineffective: (The
Time-field is a DateTime type, and I have Score and Time as Indexes)

I'm starting a project in data mining, and I'm considering Python and
Java as possible platforms.
I'm conserned by performance. Most benchmarks report that Java is
about 10-15 times faster than Python, and my own experiments confirms
this. I could imagine this to become a problem for very large
datasets.
How good is the integration with MySQL in Python?

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

Overview:
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,...
