A themeless blog
Here are my thoughts for you. Just like the way you decide, who to talk to by remaining invisible, I am going to decide whether to respond to your chat ping or not.
Once in a while u r in invisible mode, I can understand, but everyday? If you don't want other's to ping you as you are busy, set the busy status & politely tell ppl, you will get back to them. If you have a pesky friend on the list delete / block him or her.
Note: This post is not for any one person but in general to all my invisible friends.
Today morning, I was monitoring two EC2 AMI’s for their performance under load conditions for one applications in office. I was doing it in the most rudementary method, by obeserving the output from ‘top’. The last parameter in the CPU information line, ‘st’, drew my attention immediately as it was consuming nearly 60% of CPU time!
1:Def - 22:52:40 up 15:20, 1 user, load average: 7.07, 3.30, 1.44 Tasks: 110 total, 5 running, 105 sleeping, 0 stopped, 0 zombie Cpu(s): 30.9%us, 7.3%sy, 3.7%ni, 0.0%id, 0.0%wa, 0.0%hi, 0.0%si, 58.1%st Mem: 1747764k total, 1687264k used, 60500k free, 34288k buffers Swap: 917496k total, 88k used, 917408k free, 538928k cached
I guess I had missed it or never paid attention to that parameter earlier. Googled a little to find out that ‘st’ = ‘steal’, in the literal sense.
Steal time is the percentage of time a virtual CPU waits for a real CPU while the hypervisor is not scheduling this virtual CPU.
I found a very nice presentation from IBM, which explains what steal time is and why it exists –> http://t.co/XNhOIan
Anyways, here comes the Indian jugaad to rescue! I took one pin of a broken 3 pin adapter & plugged it into another 3 pin international converter adapter. This pin can be aligned to coincide with the earthing or grounding plate of the plug provided by Apple. See attached photos for better understanding.
Following up on the previous posts on configuring apache on Ubuntu, I now post the method to do the same on the Mac.
Step 1: You will need to download the mod_proxy_html module from http://apache.webthing.com/mod_proxy_html/
Step 2: Compile the code.
$ sudo apxs -ci -I /usr/include/libxml2 mod_xml2enc.c $ sudo apxs -ci -I /usr/include/libxml2 -I . mod_proxy_html.c
Then update you httpd.conf to include
LoadFile /usr/lib/libxml2.dylib LoadModule proxy_html_module libexec/apache2/mod_proxy_html.so LoadModule xml2enc_module libexec/apache2/mod_xml2enc.so
Also take a look at the proxy-httpd.conf file that ships with mod_proxy_html for additional config you may want.
This summer like every summer I could not camp, I spent my days in an AC office, hammering away at the keyboard, just like any other 'IT Worker'. Last week I saw a small window to make good an escape from the AC office to a Tiger Sanctuary, before they closed down for the monsoons. Making a mad dash, I managed to join a group of friends heading to Kanha Tiger Reserve. The forest looked just plain beautiful, with shades of green and brown. Never had I had a chance to see Kanha in this season. It seemed like all the deers in the forest had come out into the meadows to celebrate and get wet in the rains. The male chital (spotted deers) sported beautiful antlers.
This July calendar, I send across a picture of one such male Chital.Classic square monitor (4:3)To download,
