തികച്ചും വ്യതസ്തമായ ഒരു അനുഭവം ആണ് ഇവിടം.  ജീവിതത്തില്‍ ഒരികല്‍ എങ്കിലും എത്തി പെടേണ്ട  ഇടം തന്നെ.
 സിങ്കപ്പൂര്‍ എന്നാല്‍  നമ്മുടെ രണ്ടു ജില്ലകളുടെ അത്രയേ വരൂ. പക്ഷെ ഒരു മനുഷ്യന് ആവശ്യമുള്ള എല്ലാം ഇവര്‍ ഈ കൊച്ചു  ഐലന്‍ഡില്‍ ഒരുകിയിരികുന്നു .
 ഇവിടെ എത്തിയാല്‍ ആദ്യം ആരും ഒന്ന് അമ്പരുന്നു പോകുന്ന ഒരു കാര്യം വ്ര്‍ത്തിയും വെടിപും ആണ് .  എനിക്ക് ഇനിയും മനസിലായിട്ടില്ല ഇവര്‍ എങ്ങനെ വേസ്റ്റ് മാനേജ് ചെയ്യുന്നു എന്ന്.  ഒരു തുണ്ട് കടലാസോ, ഒരു പ്ലാസ്റ്റിക്‌ ബോട്ടിലോ ഇവിടേ അലസം ആയി റോഡില്‍ കിടകുന്ന്തു കാണാനില്ല.
    നമ്മള്‍  സാദാരണ യൂറോപ്പ്യന്‍ രാജ്യങ്ങളും  ആയി നമ്മുടെ വൃത്തി താരതമ്യപെടുതുമ്പോള്‍ തടി തപ്പാന്‍ പറയുന്ന സ്ഥിരം വാചകം ഇല്ലെ, “ജനസാന്ത്രത”, അത് ഇവിടേ വില പോകില്ല.  അത് ഇവിടേ നമ്മുടെ നാട്ടിലെകളും കൂടുതല്‍ ആണ്. പിന്നെ എന്താണ് ഇവര്‍ക്ക് ഇത്ര വൃത്തി ? ചിന്തികേണ്ടി ഇരിക്കുന്നു.
 രണ്ടാമത്തെ കാര്യം ഇവടുത്തെ റോഡുകളാണ്. അവിടെയും നമ്മള്‍ തടി തപ്പാന്‍ പറയുന്ന കാര്യം നമ്മുടെ നാട്ടിലെ മഴ ആണ്. എന്നാല്‍ ഇവിടേ 365 ദിവസത്തില്‍ 350 ദിവസവും മഴ ആണ്.  എന്നിട്ടും എന്താണ് ഇവിടേ റോഡുകള്‍ ഇങ്ങനെ ? അതും ചിന്തികേണ്ടി ഇരിക്കുന്നു.
 പ്രകൃതി ഈവര്‍ക്ക് പ്രതികൂലമായ സാഹചര്യങ്ങളാണ് ഒരുക്കി ഇരികുന്നത്.  കൃഷി ചെയ്യാന്‍ പാടങ്ങളില്ല, ഡാം  കെട്ടാന്‍ പറ്റിയ പുഴകള്‍ ഇല്ല,  ഒരു കുന്തവും ഇല്ല. എന്നാലും ഇവന്മാരെ സമതിക്കണം.  ഞാന്‍ ഇവിടേ എത്തിയിട്ട് ഇന്നേ വരെ ഒരു തവണ പോലും കറന്റ്‌ പോയില്ല. അത് മാത്രമല്ല മികവരും കമ്പനികളില്‍ ഒന്നും ബാക്കുപ് പവര്‍  പോലും ഇല്ല.  കാരണം ഇവിടേ കറന്റ്‌ പോകാറില്ല.
 പിന്നെ ഇവിടേ കൂടുതലും ചൈനീസ് ലുക്ക്‌ ഉള്ള ആളുകളാണ്.  അവര്‍ക്ക്  ഇന്ത്യകരെ പേടി ആണ് എന്ന് തോനുന്നു. അതിനു തക്കതായ കാരണവും ഉണ്ട് . എന്റെ അനുഭവത്തില്‍ ഒരു സംഭവം ഉണ്ടായി. പൊതുവേ ഇവിടേ ക്രൈം ഇല്ല  എന്നാണ്  ഒരു വെപ്പ്.  എന്നാല്‍ പലയിടത്തും ബോര്‍ഡ്‌ വച്ചിടുണ്ട് “Less crime doesn’t means no crime”. അങ്ങനെ ഇരിക്കെ ഒരു ദിവസം ഞാന്‍ ഓഫീസിന്നു തിരിച്ചു വരുന്ന സമയത്ത് ഒരു ഇന്ത്യകാരന്‍ ഓടി  വരുനത്‌ കണ്ടു. അവന്‍ ചാടി ഓടി റോഡ്‌ മുറിച്ചു കടന്നു പോയി, എനിക്ക് ഒന്നും മന്സസിലയില്ല, അല്‍പ സമയം കഴിഞ്ഞു ഒരു ചീനി പെണ്ണ് കരഞ്ഞു കൊണ്ട് ഓടി വരുന്നേ കണ്ടു.  അപ്പൊ കാര്യം പിടികിട്ടി .  അവന്‍ അവളുടെ ബാഗ്‌ തട്ടി പറിചോണ്ട്  ഓടിയതാ. ഞാന്‍ ഇതേ പറ്റി കുറെ പേരോട് സംസാരിച്ചു, അവര്‍ പറയുന്നത് പണ്ട് ഇവിടെ കൊലപാതകം പോലും നടക്കാറുണ്ട് എന്നാണ്.   എന്തായാലും അവര്‍ നമ്മളെ പെടികുന്നതില്‍ കാര്യം ഉണ്ട്.
 ഇവര്‍  നമ്മളെ പോലെ തമ്മില്‍ തല്ലാതെ നാടിനെ സ്നേഹിക്കുന്നു. കയ്‌ക്കൂലി  എന്താന്ന് പോലും ഇവന്മാര്‍ക്ക് അറിയില്ലാന്നു തോന്നുന്നു. അതിനു കാരണവും ഉണ്ട്.  ലോകത്തിലെ ഏറ്റവും കൂടുതല്‍ ശമ്പളം വാങ്ങുന്ന PM സിങ്കപ്പൂര്‍ ആണ് ഉള്ളത്. അത് പോലെ തന്നെയാണ് ഇവിടത്തെ നിയമങ്ങളും. അഴിമതി കാണിച്ചാല്‍ പിന്നെ അവന്‍ പുറം ലോകം കാണില്ല.
 പക്ഷെ  ഇവടുത്തെ ചില നിയമങ്ങള്‍ കേട്ടാല്‍ ചിരി വരും . “chewing gum is illegal, but prostitution is legal :P ”  ഇത് പോലെ പല നിയമങ്ങളും ഇവിടേ കാണാം. എന്തായാലും ഇവിടുത്തെ ജനങ്ങള്‍ അനുസരിച്ചോളും, ഇല്ലേല്‍ ഇവര്‍ അനുസരിപ്പികും.  രണ്ടു മാസം മുന്നേ എന്റെ ഒരു സുഹുര്‍ത്തിന്റെ വീട്ടില്‍ റൈഡ്.  റൈഡ് എന്ന് കേട്ടാല്‍ നമ്മുടെ നാട്ടില്‍ മറ്റു പലതും ഓര്മ വരും, എന്നാല്‍ ഇവിടേ അവര്‍  കൊതുകുണ്ടോ എന്ന് നോക്കാനായിരുന്നു റൈഡ്. അവര്‍ക്ക് കൊതുകിനെയും കിട്ടി അവനും ഫൈന്‍ ഉം കിട്ടി. (200s$/8000 Rs). ഇങ്ങനെ ഒകെ ആയിരുന്നില് നമ്മുടെ കൊച്ചി ഒകെ എന്നെ കൊതുക് വിമുക്തമയേനെ അല്ലെ ?
 ഇതൊകെ ആണേലും ഇവര്‍ക്ക് സ്വന്തമായി ഒരു culture ഇല്ല.  പാശ്ചാത്യ സംസ്കാരത്തെ അതെ പടി കോപ്പി അടിക്കാന്‍ ശ്രമിക്കുന്ന ഒരു പിടി മണ്ടന്മാര്‍ എന്നാണ് എനിക്ക് ഒരു മലയാളി എന്നാ നിലയ്ക്ക് പറയാന്‍ ഉള്ളത് . കോപ്പി അടി എന്നാല്‍ സയിപിന്റെ ചെഷ്ടകളെ അതെ പടി (നമ്മുടെ നാട്ടിലും, നമ്മള്‍ ഈ വഴിക്ക് തന്നെ ആണ് പോകുന്നത്, അത് കൊണ്ട് കുറ്റം പറയാന്‍ പറ്റില്ല )
ഇതില്‍   നിന്നൊക്കെ  എനിക്ക് ഒരു കാര്യം മനസിലായി, ഈ ഇത്തിരി പോന്ന സിങ്ങപൂരിനു ഇത്ര ഒകെ ചെയ്യാന്‍ പറ്റുമെങ്കില്‍ . നമ്മുടെ ഇന്ത്യ മഹാരാജ്യം ഒന്ന് മനസ് വച്ചാല്‍ എന്തോകെ ചെയ്യാം!! . പക്ഷെ നമ്മള്‍ മനസ് വെയ്കണം !!

Not Many tutorials are available for Grub 2, So I thought of writing one!

Grub 2 configurations are stored in 3 locations

  1. /boot/grub/grub.cfg -

Main config file NOTE : This file should not be edited by hand.

2.) /etc/grub.d/-

This is the grub scripts directory.These scripts are building blocks from which the grub.cfg file is built. When the relevant GRUB command is executed, the scripts are read in a certain sequence and grub.cfg is created.

 

Sample grub.d contains the following files..

00_header is the script that loads GRUB settings from /etc/default/grub, including timeout, default boot entry, and others.

05_debian_theme defines the background, colors and themes.

10_linux loads the menu entries for the installed distribution.

20_memtest86+ loads the memtest utility.

30_os-prober is the script that will scan the hard disks for other operating systems and add them to the boot menu.

40_custom is a template that canbe used to create additional entries to be added to the boot menu.

The numbering defines the precedence of the scripts.

3. /etc/default/grub -

This file contains the GRUB menu settings that are read by the GRUB scripts and written into grub.cfg. It is the customization part of the GRUB, similar to the old menu.lst, except the actual boot entries.

There are many other files also in this directory. The grub file is a text file that is parsed by the 00_header script.

Sample file:

# If you change this file, run ‘update-grub’ afterwards to update
# /boot/grub/grub.cfg.

 

GRUB_DEFAULT=0
#GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash”
GRUB_CMDLINE_LINUX=”"

 

# Uncomment to disable graphical terminal (grub-pc only)
#GRUB_TERMINAL=console

 

# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo’
#GRUB_GFXMODE=640×480

 

# Uncomment if you don’t want GRUB to pass “root=UUID=xxx” parameter to Linux
#GRUB_DISABLE_LINUX_UUID=true

 

# Uncomment to disable generation of recovery mode menu entries
#GRUB_DISABLE_LINUX_RECOVERY=”true”

 

# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE=”480 440 1″

 

 

Note: Many more settings are available

Working

All customizations are done in /etc/default/grub and /etc/grub.d/ scripts. When the update-grub command is run, it reads the contents of the grub file and the grub.d scripts and creates the grub.cfg file.

 

Adding new entries/script

To add a new boot option, you will have to follow a basic syntax:

a) Create a new file that has a XX_ prefix in the name, where XX is a sequence of numbers.

b) The next step is to write the actual content. Here’s a sample:

#!/bin/sh -e

echo “Adding my custom Linux to GRUB 2″

cat << EOF

menuentry “My custom Linux” {

set root=(hd0,5)

linux /boot/vmlinuz

initrd /boot/initrd.img

}

EOF

GRUB 2 uses PARTITION notation that starts with 1 and not 0 like GRUB legacy! sda1 is now (hd0,1) and NOT (hd0,0) as before

Anything inside “cat << EOF EOF” is grub commands and outside that is interpreted by the shell.

To know about what commands grub2 suppots, you can check the link : http://grub.enbug.org/CommandList.

Make sure scripts in /etc/grub.d/ are having execute permission.

Once the script is ready, you can type update-grub

So when you feel you want to convert some videos to other formats, dont look for those long ffmpeg commands, you could just install winff.

Note: Make sure you install libavcodec-extra-52 to avoid libmp3lame errors.

sudo apt-get install ffmpeg libavcodec-extra-52

Since this was held in a famous temple, I thought of going in traditional kerala dress(mundu).

In my opinion, mundu is the costume that suits our hot climate. But there is one problem with wearing mundu, we need to manage everything in our shirt pocket (phone, wallet etc).

All went fine, except the return journey from calicut bustand to my home. That bus had an unusual rush, but still I managed to get in. After bus passed few stops, I noticed one guy bringing his face towards me, I certainly felt strange and stepped back. He continued to do that, this time I tried to keep as far as I can from him. After that, he didnt come to bug me. I felt, “ah..All is fine now..”

Few minutes later I felt something wrong and when I checked

MY PHONE IS MISSING!!!OH MY GOD

I turned back to see whether that guy is there, No.. he is not there. I rushed to the door, huh.. there he is waiting to get down in the next stop(pottammal). I shouted at him, GIVE ME THE PHONE!! He took his phone and showed me.

I decided not to leave him like that, I caught him tight and pulled him back from foot board. By that time bus reached pottammal bus stop, and many people were trying to get in and suddenly one guy among them said … “Hey here is a phone lying on the foot board”. Ah, I tried to pick it from floor, and by that time that #$#$%$#%#$^ jumped out and ran away . !!!!! Feel so ashamed that I missed him..

NOTE:: Anyway happy that I got my sweet android back :-)

But Now, its serving from 2 servers instead of 1. From US dc and from Indian!!

This is done mainly to avoid latency and a step from my end for holding our traffic. If you are my regular reader, you will understand what I mean. “Why can’t we hold our traffic”

Something like that happened with planet.

I cant even imagine that the brandname planet is going to disappear soon, merged with softlayer to compete with Rackspace.

Even though I am able to fix the issue, I felt slowness in accessing the office PC. When I checked my internet speed, its normal. Then why this latency ?

I am using Bsnl and in my office asianet leased line is used. I am at calicut, nearly 500kms from my office. But when I checked the route of my packet, I am pretty amazed.

Means, the packet is exchanged from Mumbai. Packet is traveling (1200 * 2 kms simply to exchange between ISPs)

Yes, its true there is no Internet exchange point in my Place !!!! That is what I understand from all these. NIXI is responsible for national Internet exchange in India.

NIXI currently has seven operational nodes at the centers in Delhi (Noida), Mumbai (Vashi), Chennai, Kolkata, Bangalore, Hyderabad and Ahmedabad.

My question is why cant others come up with Internet exchange points like NIXI all over India? Is it possible ?

A short Description of  NIXI

The National Internet Exchange of India (NIXI) is a non-profit Company established in 2003 to provide neutral Internet Exchange Point services in the country. It was established with the Internet Service Providers Association of India (ISPAI) to become the operational meeting point of Internet service providers (ISPs) in India. Its main purpose is to facilitate handing over of domestic Internet traffic between the peering ISP members, rather than using servers in the US or elsewhere. This enables more efficient use of international bandwidth and saves foreign exchange. It also improves the Quality of Services for the customers of member ISPs, by being able to avoid multiple international hops and thus lowering delays.

Here it is.

I am not your client, but been in webhosting field for the past 6 years.  Hope you are aware of the recent bom-sabado worn that hit orkut.

http://research.zscaler.com/2010/09/new-orkut-worm-bom-sabado-good-saturday.html

I could see the domain tptools.org,  under which the worm was hosted is in your gator1237.hostgator.com. server. Seeing the whois details of this domain, it seems it was hosted by the hacker itself. Also, no update is being done to his nameservers after 19th. Can you analyze your network/system logs to shed some idea of the hacker?

Yesterday, one guy came to me with a website which is having a huge downloads and connections.

When I logged in to the server and checked the load was 100-400 and websites/control panel everything was slow.

The server had good configuration and he was in a confusion to make things work better.

So i told him, I will do some optimization for better performance. But it didnt make any difference.

Next I changed the apache mpm from prefork to worker. It showed some positive signs, but still was not up to the mark.

Then I decided to run 2 webserves, one nginx to server static contents and apache in the background for serving dynamic contents.

I will explain the steps to do that.

cd /usr/src
wget http://sysoev.ru/nginx/nginx-0.7.63.tar.gz
wget http://stderr.net/apache/rpaf/download/mod_rpaf-0.6.tar.gz
wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-7.9.tar.gz
tar xvzf mod_rpaf-0.6.tar.gz
cd mod_rpaf-0.6
/usr/local/apache/bin/apxs -i -c -n mod_rpaf-2.0.so mod_rpaf-2.0.c
cd /usr/src
tar xvzf pcre-7.9.tar.gz
cd pcre-7.9
./configure
make
make install
cd /usr/src
tar xvzf nginx-0.7.63.tar.gz
cd nginx-0.7.63
./configure --with-http_ssl_module --with-http_realip_module --with-http_dav_module --with-http_flv_module --with-http_gzip_static_module
make
make install

-Login to WHM and look for the following route:
Main >> Service Configuration >> Apache Setup > Include Editor > Pre Main Include

- Add the following configuration and save, LIST_OF_YOUR_IPS changing the IP you occupy in your site:

LoadModule rpaf_module modules/mod_rpaf-2.0.so
RPAFenable On
# Enable reverse proxy add forward
RPAFproxy_ips 127.0.0.1 LIST_OF_YOUR_IPS
# which ips are forwarding requests to us
RPAFsethostname On
# let rpaf update vhost settings
# allows to have the same hostnames as in the "real"
# configuration for the forwarding Apache
RPAFheader X-Real-IP
# Allows you to change which header mod_rpaf looks
# for when trying to find the ip the that is forwarding
# our requests
Change the apache port to 81 (tweak settings)
Open whm – tweak settings and find 0.0.0.0:80 and change it to 0.0.0.0.:81
- Run SSH console


/usr/local/cpanel/whostmgr/bin/whostmgr2 --updatetweaksettings
/scripts/rebuildhttpdconf
httpd restart




wget the automated nginx virtual host creator and run it


http://prajizworld.com/nginx.sh




chmod 755 nginx.sh


./nginx.sh




Remove the 3 # signs of the following lines from


 /usr/local/nginx/conf/vhost.conf




#location ~* \.(gif|jpg|jpeg|png|wmv|avi|mpg|mpeg|mp4|js|css)$ {


# root   /home/myweb/public_html;




#}








Check nginx configuration  using



/usr/local/nginx/sbin/nginx -t




 If everything is fine, its time to  start nginx.




/usr/local/nginx/sbin/nginx




Configure nginx startup script




http://prajizworld.com/nginx.txt


mv nginx.txt /etc/init.d/nginx


chmod +x nginx


chkconfig --add --level 3  nginx




After doing all these, the server load was very low and pages were processing at lightning fast,


but still we experienced a slowness.


 When I analyzed the traffic, I understood now network is bottleneck.


I could see many concurrent connections from same session downloading huge files.


 So I thought of adding the below lines to limit traffic from same session




### Directive describes the zone, in which the session states are stored i.e. store in slimits. ###
### 1m can handle 32000 sessions with 32 bytes/session, set to 5m x 32000 session ###
       limit_zone slimits $binary_remote_addr 5m;

### Control maximum number of simultaneous connections for one session i.e. ###
### restricts the amount of connections from a single ip address ###
        limit_conn slimits 2;




And then, everything is working fine and the client is happy :-)

Update on Google Wave
8/04/2010 02:00:00 PM
We have always pursued innovative projects because we want to drive breakthroughs in computer science that dramatically improve our users’ lives. Last year at Google I/O, when we launched our developer preview of Google Wave, a web app for real time communication and collaboration, it set a high bar for what was possible in a web browser. We showed character-by-character live typing, and the ability to drag-and-drop files from the desktop, even “playback” the history of changes—all within a browser. Developers in the audience stood and cheered. Some even waved their laptops.

We were equally jazzed about Google Wave internally, even though we weren’t quite sure how users would respond to this radically different kind of communication. The use cases we’ve seen show the power of this technology: sharing images and other media in real time; improving spell-checking by understanding not just an individual word, but also the context of each word; and enabling third-party developers to build new tools like consumer gadgets for travel, or robots to check code.

But despite these wins, and numerous loyal fans, Wave has not seen the user adoption we would have liked. We don’t plan to continue developing Wave as a standalone product, but we will maintain the site at least through the end of the year and extend the technology for use in other Google projects. The central parts of the code, as well as the protocols that have driven many of Wave’s innovations, like drag-and-drop and character-by-character live typing, are already available as open source, so customers and partners can continue the innovation we began. In addition, we will work on tools so that users can easily “liberate” their content from Wave.

Wave has taught us a lot, and we are proud of the team for the ways in which they have pushed the boundaries of computer science. We are excited about what they will develop next as we continue to create innovations with the potential to advance technology and the wider web.

I am really wondering why google is going to drop such a wonderful project. Ofcourse, as expected no one is using the wave.

Is it because lack of marketing ?

No, I don’t think so. At first, when they released it everyone was amazed by its features. So what actually went wrong ?

Personally speaking, major reasons are

1. Its not so easy to use.

Most of us gets confused with such a large options, even though they are very useful. Some one needs to read its documentation or need to watch video tutorial in order to be an expert.

2. The entire browser gets slow down

Yes, I had to restart my browser couple of times. Even while using google chrome.

3. Google could have integrated all these to their existing webmail interface. Because no one wants to open another tab just to communicate through wave.

By chance I noticed some news about underground cable disruptions near italy, which might be causing this slowness.

This cable is a consortium of 16 companies (including Airtel and Tata Communications) and carries telecommunications between Singapore, Malaysia, Thailand, Bangladesh, India, Sri Lanka, Pakistan,United Arab Emirates, Saudi Arabia, Sudan, Egypt, Italy, Tunisia, Algeria and France.

So guys, don’t get agitated if your net goes slow in the coming days until the repair is complete.

Labor and resources are cheap here in India, but why ? Are we importing something for cost to shootup like this? The answer is, we are are simply wasting Bandwidth and paying more for it.

Why do we host a website in a server in US, while most of its customers are in INDIA?.

If we need to host here, we need more reliable datacenters here. So why there is not much datacenters here ? The answer would be bandwidth and connectivity. Since bandwidth cost is high here, we try to host servers in US, which will again increase the network traffic to US. Its a chain process and I am pretty sure we are not in the right path, which will end in a permanent solution.

ISPs here cannot reduce their cost because international bandwidth is a bit costly for them too, which restricts them to reduce bandwidth cost beyond a limit. But they are charging the same for local traffic and international traffic, where local we have got TERABYTES of bandwidth and international which is limited. It is like paying ISD rates for all calls.

My opinion as a solution for this problem is, our ISPs should start providing bandwidth based on traffic, whether it is local or international. They can give local bandwidth at very cheap prices, even cheaper than US and international can remain the same. Once this is accomplished, more datacenter startups will emerge here and there would be great difference in the international traffic.

Also there is much difference in response times,

To a Website Hosted in US

time=326 ms

To a Website Hosted in India

time=51.7 ms

So now I think If we get such a plan from Any ISPs here, I could even go for a startup in this field :-) , What do you think ?

Felt bad when I saw this. I dont know why this happened, but I am sure we will make it next time :-)

I was thinking what is this Cryogenic technology, that makes it so complex for us ?

A cryogenic rocket engine is a rocket engine that uses a cryogenic fuel and/or oxidizer, that is, its fuel and/or oxidizer are gasses liquified at cryogenic temperatures.

The use of liquid fuel rocket engines was first considered by the German, American and Soviet engineers independently, and all discovered that rocket engines need high mass flow rate for both liquid oxidizer and fuel, for generating the necessary thrust. Higher thrust levels were achieved when liquid oxygen (LOX) and liquid hydrocarbon were used as fuel. At room temperature and pressure, oxygen and low molecular weight hydrocarbons are in gaseous state. To get the required mass flow rate, the only option is to feed them to the engine in liquid form. Therefore, they are converted to liquid form by cooling them down, and are stored in the rocket’s fuel tanks at very low temperatures. Hence engines that use these fuels are called cryogenic rocket engines.

Various cryogenic fuel-oxidizer combinations have been tried, but the liquid oxygen (LOX) oxidizer and liquid hydrogen (LH2) fuel combination is one of the most widely used. Both components are easily and cheaply available, bio-friendly, non-corrosive and when burned have the highest entropy release by combustion, among all non-toxic pairs. Liquefaction temperature of oxygen is 89 kelvins and at this temperature LOX achieves a density of 1,140 kg/m3 (1.14 g/cm3). And, for hydrogen it is 20 kelvins, a few kelvins above absolute zero, and gains a density of 70 kg/m3 (70 mg/cm3). All cryogenic rocket engines work on expander cycle or gas-generator cycle or staged combustion cycle depending on thrust requirement, since the oxidizer and fuel are at sub-zero temperatures. LOX LH2 cryogenic rocket engines produce specific impulse up to 450 s (4.4 kN·s/kg).

I thought of writing a simple Server monitoring script that can monitor the services and update via Twitter.

You can download the script from http://sourceforge.net/projects/servtweet

Installation

Installation is pretty easy. The first thing you need an extra Twitter account for monitoring. Once it is created you can continue with the steps.

1. cd /usr/local/src/
2. Download the tar file from http://sourceforge.net/projects/servtweet/
3. tar -zxf servtweet.tar.gz
4. cd servtweet/
5. sh install.sh
6. Enter the Details Requested by the script.
7. Done, Just follow the twitter account, you will be getting tweets from the server in case of
Load Spikes
Apache Failure
DNS Failure
SMTP/POP Failure

Happy Twitting.

NOTE: Contact me if there is any bugs !!

Its not the first time he is coming here, but this time, its first that we are going to part, even for a while in the past 3 years.

This makes me think of our miserable and short life, full of happenings that comes as waves. Some keep us comfortable and others that might even take us down. I do believe that everything happens for a reason, so I guess this has also got something to do with my life, and probably his.

Yes, its true that many changes took place in the past few years, and it would change the same way the coming years also. But as everyone does, I too wish if I could hold those good moments without any change.
