"Owner company already exists" OpenGoo

An amazing error "Owner company already exists" was popped out while working on Opengoo migration.

It was caused when the admin user installing Opengoo was deleted

This was in the version 1.5.3

Couldn't find MIME type application/octet-stream.

KDE returns "Couldn't find MIME type application/octet-stream" at startup and/or Konqueror returns the same error message when launching whatever application.

Start the Control Center and open KDE Components/File Associations, you will see something like
Expand "application", you will probably see that there's no entry for "octet-stream".
Click on "Add...", for "Group" select "application" and for "Type Name" fill in "octet-stream". This should fix it.

It solved

Error 1 in APACHE

Dear Ostwald,
Greetings,

I have been using xampp for linux for a long time, and had not reported with any errors. But, just today I got an error reporting. Error 1: ..... So, I went through FAQ pages and searched in other search engines too, but could not find any proper answer that could solve my exact problem.

Then I started to have trials on my own. But, it was mystical when I found a log file named apachestart.log. Since the error was reported while starting apache, it had the error which i had expected. Why I mentioned this here, is because this file name is not included in the FAQ page, And as you have mentioned to email at this address, I am doing the same.

Regards,
Dhruba Adhikari

Error:1235- This version of MySQL doesn't yet support 'LIMIT & IN/ALL/ANY/SOME subquery'

If you try the following you will find it fails in mysql version 4.1,

SELECT
COUNT(*)
FROM
TABLE_1
WHERE
ROW (PK_PART_1, PK_PART_2) IN
(
SELECT
PK_PART_1, PK_PART_2
FROM
TABLE_2
LIMIT
10 -- This is the basis of the whole idea
)
AND
Whatever;

The above fails with the warning ...

ERROR 1235 (42000): This version of MySQL doesn't yet support 'LIMIT & IN/ALL/ANY/SOME subquery'

However, you can get the desired behaviour with a slight rewrite...

SELECT
COUNT(*)
FROM
TABLE_1
INNER JOIN
(
SELECT
PK_PART_1, PK_PART_2
FROM
TABLE_2
LIMIT
10 -- HEY HEY!
) AS VIRTUAL_TABLE_2
ON
TABLE_1.PK_PART_1 = TABLE_2.PK_PART_1 AND
TABLE_1.PK_PART_2 = TABLE_2.PK_PART_2
WHERE
Whatever;

And it works like a charm!

Segmentation Fault (core dumped)

I have been working on opengl environment for my graphics project and I frequently get error messages like segmentation fault. When I went through some of the googlings I concluded that one of the reason to report such type of error messages is the unauthorised access to the memory location. That is trying to access the memory which wasn't allowed to do that.
