I was recently asked this question in an interview. Unfortunately I was
not able to answer it and the interviewer made a decision on my C
strengths (or weekness) based on this single question and that was a
sad end to my interview. Here is the program:
#include <stdio.h>
int main()
{
char *c ="abc";

I'm hoping there's someone here with experience in building the Visual
Explain tool from Red Hat. I downloaded it and the J2 SDK, but when I
attempt to follow the build instructions, I get messages like:
error: Type `JTableHeader' not found in the declaration of the local
variable `header'.
JTableHeader header = null;
To me, this indicates that the SDK isn't installed (properly). But I
admit I'm pretty much a Java...

I have been using the EXPLAIN ANALYZE command to debug some performance
bottlenecks in my database. In doing so, I have found an oddity (to me
anyway). The "19ms" total runtime reported below actually takes 25
seconds on my computer (no other CPU intensive processes running). Is
this normal for EXPLAIN ANALYZE to report a total runtime so vastly
different from wall clock time?
During the "explain ANALYZE delete from msgid;" the CPU is...

Not having earned my DBA badge from the scouts just yet I'm a little
lost with an error I'm getting.
We've just upgraded our development database from 7.2 to 8.2 as the
first step in upgrading our wider environment. Of course, development
doesn't stop so I'm running some explain plans over some new views. The
problem is, when the view is accessed as part of the explain plan
script, the following error is returned.

Hi - I'm new to javascript and I was reading the book Javascript
Professional Projects - there is a fragment that has me a little
perplexed, and I was wondering if anyone could explain why and how it
works.
How is it that setting a property to null alters another property?
For example setting
optionObject.options = null;
seems to set optionObject.selectedIndex to -1 automagically.
Can you attach "hooks" in javascript that get called...

Hi All,
Here is the code which generates Segmentation Fault. Can anyone explain why the third printf fails and the first printf works?

Hello,
one sql statement is causing severe performance issue. The problem occurs only in UDB environment, the same statemnt on the mainframe is running fine. I have an explain output from the sql. The statement itself is not that complicated, it is 3 selects and union all. Explain output is pretty big, but I could not find anything unusual. I'm new to db2 and I could be missing stuff. I am posting the explain output below and I really...

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,...

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...
