Check USB harddisk mounted or not in Linux

Today, I am checking how to use a script to check if USB hard disk is mounted or not in Linux.

After doing research, I developed the following script to check “mount” status.

1. Create a file chk_mount.sh.
2. chmod 755 chk_mount.sh
3. Add the follow content to “chk_mount.sh”.

if mount | grep sdb1 > /dev/null
then
        echo "sdb1 mounted"
else
        echo "No sdb1"
        mount /dev/sdb1 /backup
fi

If sdb1 is mounted, there is no action will be taken.
If sdb1 is not mounted, /dev/sdb1 will be mounted automatically.

You can put this script in cron job and check  mount status regularly.

PowerPoint 2007 Slow Text Editing

Recently, I am facing a problem that typing or editing text in powerpoint 2007 is very slow.

I faced this problem in RTM and SP2.

After doing research on Internet, a lot of people said that it is related to printer driver issue.

I tried their suggestion. Problem cannot be fixed.

After a further searching in Internet, it suggested to enable hardware acceleration in PowerPoint 2007.

I tried this approach. It works for my case.

MS will not provide hardcopy certificate anymore

Today, I receied July 2009 MCP Flash. It has big news. MS will not provide hardcopy certificate by default. If you need hardcopy, please pay $$$.

In my career, I took a lot of MS exam and got a lot of MS certificates. If they need me to pay extra $$ for my certificate, I will consider to end my MS certificate plan.

If you are not agree to MS new certificate arrangement, please goto the following url to express your angry and complain.

http://borntolearn.mslearn.net/2009/06/going-green-mcp-digital-certificates-are-here/comment-page-6#comment-2565

I left my comment to this url too.

Actually, I paid a lot of effort to take different MS exam from NT4 to Windows 2008. If exam will not provide paper printout certificate any more, I consider to discontinue my MS cert path in coming future. And in my peer group, I am one of the driver to encourage my peers to take MS exam. In coming, I will discourage my peers to take MS exam and technology. I am strongly disappointed to this arrangement.

I would like to propose the following suggestion for MS if they are really consider to our voice.

1. establish a plan for existing holder to choose to maintain the existing plan. They can order paper certificate w/o paying extra shipping and handling charge

2. Discount the exam fee (Not a short period to CHEAT user), deduct whole shipping and handling fee.

3. Send me an official email and tell me that it is MS new arrangement.
And please note it in the email “if you don’t accept it please do not use MS product”.

I am vvvvvery angry w/ this new arrangement.

I just planned my OCS and W2K8 virtualization in coming months. I will cut it. And I won’t suggest OCS as Enterprise Voice and IM solution to my customer. I will not suggest Hyper-V as Virtualization platform.

I will not take Win7 exam for driving new Desktop deployment.

Virtual Server to VMware Server

Previously, I built my testing lab by using Virtual Server 2005 SP1.
Currently, I am running VMware Server 2.0 (64-bit) in my Vista box. And I am going to convert vhd file to VMware Server.

I downloaded VMware Converter 4 from VMware.com. I found that this tool can help me to migrate vhd file to VMware server easily (Very Easy).

Screens:

vm-conv-01

vm-conv-02

vm-conv-03

vm-conv-04

vm-conv-05

vm-conv-06

Complete convertion.

vm-conv-08

You can find converted file in your defined path.

vm-conv-08

Add this VM to VMware datastore.

VMware Server Disk Performance Tuning (Example)

I found my VMware Server (Version 1.09) Linux Host running very slow when one of the guest OS doing backup.

Whole system is not responding while doing backup. This made me crazy for long time.

Yesterday, I tried to do some research about Disk Performance tuning.

Finally, I tried these settings and it works for my VMware Server Linux Box.

You can open the configuration file *.vmx and add the following lines to the configuration file.

# VMware Disk Performance tuning
mainMem.useNamedFile = "FALSE"
sched.mem.pshare.enable = "FALSE"
MemTrimRate = "0"

Wow, after adding it. Performance improved a lot :) . (Don’t ask me for the figure). I am lazy to do benchmark.

Tenor A400 DTMF inband with Asterisk

Tenor A400 DTMF inband with Asterisk

When you are using A400 to access Voicemail provided by Asterisk, you may not be able to submit the “digit” or “key” to it.

If you are facing this case, you can consider to do the following configuration.

1. In Asterisk sip.conf,
Configure
dtmfmode=inband

2. In A400,
Configure
dsp digitrelay 1

digitrelay

digitrelay

Description: Digit Relay. Used to set how the Tenor sends DTMF tones during a VoIP call. Sending DTMF tones in-band (the same path as the voice) over IP is extremely unreliable. It is not uncommon for these tones to be misinterpreted as a different digit than what was entered. Therefore, the Tenor, by default, will regenerate the tones in that, when a Tenor senses that a user has pushed digits during a call, the Tenor will translate the tones to the literal digit, send that information over IP to the destination Tenor. The destination Tenor will convert the digit back to a tone and insert it on to the correct voice path. This provides a high degree of accuracy when sending DTMF tones. However, some devices, such as Microsoft’s NetMeeting, do not support this method and can only send the digits in-band. This command allows you to choose the DTMF method.

Windows 7 System Requirement

After reading Windows 7 System Requirement,I puzzle that why memory requirement for x86 and x64 is different.

Basically, my understanding is that x64 can locate more memory address space than x86 architecture.

I don’t know why memory requirement for x64 Windows 7 is higher than x86?? 1GB vs 2GB ?? 50% more ???

x64 needs more RAM???? I wonder if there is any MS product team guy can explain it more. It is interesting that why x64 needs more memory for running Windows 7.
