<b>the Human Journey:</b> "...while servers are individually more important, you can far more easily, cheaply, and effectively test and upgrade your server fleet than you can your desktops and laptops."
As a DBA you always followed a practice to back up your database (or take a snapshot of your database) before making any changes so that you can revert to your old database state if something goes wrong. Also to setup a development or test environment you use a backup of your database and restore it in the respective environment. If you are moving to SQL Azure, what would you do in these cases as backup / restore and database snapshots are not supported as of now?
Hello all, I have met something pretty odd. I am running a serialization on an object and not always the size of the output stream is the same. I even created a test that I am running the serialization in a loop, and each time I am running I have different results sizes in some point in the loop. This happens when I am using a object that was filled in the server side, and I get them thru WCF work...
I am trying to choose the row where
1)list.ispublic = 1
2)userlist.userid='aaa' AND userlist.listid=list.listid
I need 1)+2)
There is a row already but this statement can not get that row, is there any problem?
List table:
ListID ListName Creator IsRemindSub IsRemindUnSub IsPublic CreateDate LastModified Reminder
1 test2 aaa 0 0 1 2012-03-09 NULL NULL
user_list table (No row):
UserID ListID UserRights
My test version
SELECT l.*, ul.*
FROM list l
INNER JOIN user_list ul ON ul.ListID = l.ListID
WHERE l.IsPublic = 1
AND ul.UserID = 'aaa'
There is zero result. How can I fix that?
i have created a snapshot that takes data from 2 tables and has a refresh rate of 1 day.
The snapshot data is not refreshing it is still the same. is there something that i am
missing ?
Here is the code:
CREATE SNAPSHOT test
REFRESH COMPLETE
START WITH SYSDATE
NEXT sysdate + 1
AS
select item_code,item_conc_code,tran_bran_code,sum(tran_qty) bal_qty
from tranhist a,
itemmast b
where a.tran_item_code = b.item_code
group by item_code,item_conc_code,tran_bran_code
With a large-scale development of a database application, the task of supporting a large number of development and test databases, keeping them up to date with different builds can soon become ridiculously complex and costly. Grant Fritchey demonstrates a novel solution that can reduce the storage requirements enormously, and allow individual developers to work on thir own version, using a full set of data.
I installed Skype 4.2 via PPA on my fresh 14.04 system.
Skype itself makes notification sounds (though distorted), but when I am in a conversation, I receive neither sound, nor video. I tested it with my mom, she could hear and see me, but I couldn't see or hear her, and the sound test is quiet too.
I didn't install any additional drivers yet, as I'm much of a newbie I'm not sure which ones to choose. Please let me know if you need any command outputs.
I want to test deployment of a Windows application and a virtual PC seems the easiest method (I could be wrong, feel free to comment, but the question still stands). Courtesy my Windows 7 I have Virtual PC, and I seem to recall way back in XP I could download a pre-made image for Virtual PC 200x(7?) and use that without having to install from media.
Are there any similar images for developers for Virtual PC?

Due to rather strange circumstances, I only have until Monday to learn (at least) the basics of PHP and .NET programming. I'm already fairly competent (though there is a lot of room for improvement) in C++ so I feel I have some of the concepts nailed already, but I need to get into the two languages in a bit more depth in a very short time frame.
Unfortunately I won't have time to get any books so will need to exclusively use online resources, I'm more of a 'do-er' so any way to test my skills in a practical way would be a huge bonus :-)
I've made a simple 2D game engine using C# and DirectX and it's fully functional for the demo I made to test it. I have a Timer object that uses QueryPerformanceCounter and I don't know what's the better choice: use only one timer in the game loop to update everything in the game, or an independent timer in every object that needs one.
My worry is that when I try to implement threads, what will happen with timers? What happens with the sync?
Few mail servers have been presented as Exchange alternatives as long as GMS has. In its most most recent release Gordano added a document management system and various other functionality. We test drive the Linux version on an Intel box.
I am using CK editor to post the content. When I just type a simple text manually, It just appears as it was.But the problem is when I copy the test from other websites like wikipedia, an empty paragraph is rendered in the beginning of the string, which is making my page look odd. I have tried using trim,and preg_replace. But I did not find any solution.
Please suggest some method to overcome this issue..
Thanks
I want to share a folder for two users, here is what I did:
created group
add users to group
set chmod
set chown
set setgid 2775
reboot
After that:
echo test > /Common/testfile - group readable&writable
Created file using Nautilus - group readable, but not writable
Copied file using Nautilus - group readable, but not writable
Created file using gedit - group readable&writable
Why? Is it a bug? This was on a clean Ubuntu 10.10 installation.
You are about to read the best Google SEO advice that anybody will ever give you. At first site it may appear to be nothing much but don't be fooled into taking it at face value. Look at it again and again and test it and study it deeper. You will never regret it.
My team is developing an app that will work on about 100 (or more) different android devices.
We are having trouble testing it since we are not sure how to verify if it works on all the different devices.
Can anybody suggest some best practices, a testing framework, or some sort of way to give us feedback on how to test our app and/or get feedback from our users so they can tell us the problems they are having?
We all understand the value of Unit Testing, but how come so few organisations maintain unit tests for their in-house applications? We can no longer pretend that unit testing is a universal panacea for ensuring less-buggy applications. Instead, we should be prepared to actively justify the use of unit tests, and be more savvy about where in the development cycle the unit test resources should be most effectively used.
