In this part I’ve connected the second IR sensor and Light sensor.
As you can see in the video when the light sensor is covered Arduino gives my a sign that it is night time by running Leds from one end and back.
At the moment there is a delay until the lights  starts switching off if during the delay any of the IR sensors are crossed the delay starts counting from the beginning.

While testing I’ve noticed that some Leds instead of dimming just switch off. Reading through Arduino forum I’ve found that apparently Arduino can only to analogWrite() on digital pins 3, 5, 4, 9, 10 and 11. This is what I most liekely will have to live with or maybe get myself  Arduino with ATmega.

Hi Everyone,
This post will be something different compared to the posts on this blog but it is still ralated to IT.

About a year ago I’ve found out about Arduino and really liked what can be done with it and how easy it is to use. So I’ve bought it…. Well needles to say I played around with for day or 2 and forgot about it.
Couple months ago I saw Automatic LED stair lighting posted on YouTube see the video bellow:

Last week after rebooting one of the servers was not coming up.
After connecting to it using iLO I’ve found it stuck on boot screen. It was saying Smart Array initializing. This initializing process should take a second and it should find or not find any logical drives and move to the next step.
The problem was fixed by replacing the Cache memory in Smart Array controller. The server would experience exactly the same problem if you try to boot the server without the cache. Well at leas that is the case on BL25 G2 with E200 Smart Array controller.

Here is some interesting problem with RSA ACE server that I’ve encountered.
Symptoms:
1. The servers is restarting automatically. You are able to login but after a minute or sow you get the message with counter ‘System Shutdown:This System is Shutting down. Please save all work in progress and log off. Any unsaved changes will be lost’
The message should tell you that RSA ACE is restarting the server.

2. In Event viewer Application. You should see plenty of ACESERVER 15004 errors.
In systems event log you should see many Service Control Manager 7031 errors.
Under services most Automatic RSA ACE services would not be running and when you try to start RSA ACE/Server authentication engine it would not start.

Here is an error that I’ve seen on couple installations:

SMS Active Directory System Discovery Agent failed to bind to container LDAP://DC=domain,DC=xxx. Error: The server does not support the requested critical extension.
.
Possible cause: The AD container specified earlier might be invalid now. The Domain Controller is inaccessible.
Solution: Please verify that the AD container paths specified are valid. Confirm accessibility of the site server to the Domain Controller to be queried. Continue reading SCCM: SMS_AD_SYSTEM_DISCOVERY_AGENT, Message ID: 5204 →
