Oh no! It's me and transactions again :)
I'm not really sure whether this is a limitation of psycopg or
postgresql. When I use multiple cursors in a transaction, the records
inserted at the start of the transaction aren't visible to those later
on in that transaction (using a different cursor).
Attached is a simplified example (the except's are a bit blunt, I know)
of what I'm trying to do. In reality, the different cursors are...

Take some standard code such as shown below. It simply loops to add up a
series of terms and it produces the correct result.
// sum numbers with a loop
public int DoSumLooping(int iterations)
{
int result = 0;
for(int i = 1;i <=iterations;i++)
{
result += i;

Hi there,
the Code below shows DJBs own implementation of strlen (str_len):
unsigned int str_len(char *s)
{
register char *t;
t = s;
for (;;) {
if (!*t) return t - s; ++t;

Hey Ppl,
I'm developing an Online Auction Site using ASP.net and am
experiencing a problem with Transactions in ADO.Net.
When beginTrasaction() function is invoked from a specific connection,
and insertions are made into a table, no other connection can access
the table, until the transaction is committed. I've set the
Isoloation level to ReadUncommited.

I'm using dotNet 2.0 and VS2005, I would like to have some code call several
webservices that I have written that insert data into a DB (MSSQL 2000)
inside a transaction. So that I can rollback if something goes wrong. Can I
support transactions across webservices on different frontend servers? And
if so how?
I've tried to google for it but haven't found anything yet.
Kind Regards,
Allan Ebdrup

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:

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,...

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.

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...
