Troubleshooting serial link through soft Loopback testing on CISCO Routers
http://technicafe.net/2012/05/troubleshooting-serial-link-through.html
Note: Softloop test should only be performed when serial link is down. If performed when the link is up, it will effect the data transmission.
Troubleshooting serial links is always critical issue in networking world. One of the smarter way to test the connectivity through different hops by looping, which can either be software based or hardware based.
Soft looping:
Soft looping is a method which feeds a required signal or data, back to the sender. Through soft looping physical connection problems, passing through various Hops can be rectified. In Cisco routers, soft loopback is implemented with a Cisco IOS configuration command, or with a loopback button on some CSU/DSU.
(Channel Service Unit/Data Service Unit)
While working on a leased line or dedicated line, provided by ISP, there are times when we know there is some issue in leased line, then we can perform loopback test through our Cisco IOS and can do some measurement to rectify the exact problem.
In Cisco IOS, following soft loopback modes can be applied while testing :
Local : Loops the router data towards router and sends AIS towards the network.
Syntax :
loopback [remote {line {fdl ansi | inband} | payload fdl ansi}]
Link status can be analyzed through show interface serial x/x/x:x command in Cisco IOS. Point to remember is that whenever an interface will be looped, the output of show interface command will always be showing serial x is up, line protocol is down(looped).

CNAME
CNAME, and CNAME record
Short for canonical name. a record in a DNS database that indicates the true, or canonical, host name of a computer that its aliases are associated with. Sometimes more than one domain name resolves to the same IP address, and this is where the CNAME is useful. A machine can have an unlimited number of CNAME aliases, but a separate CNAME record must be in the database for each alias.

DNS Records - resolve
A record vs. CNAME (A used for IPv4, AAAA for IPv6)
1. How to create a CNAME to point rejiao.com to home.com
advantages
-Quickly change the IP address for a group of records; you just change the IP of the A record instead of all the records
-Point your record to a zone entry you don't control (e.g. www.mydomain.com. IN CNAME www.someotherdomain.com.)
-even if IP address of the host is changed, DNS server doesn't require any change.

Palm tree paradise and "Cats and Dogs"
Wow, at 23:03 in Tokyo, it's deadly raining "cats and dogs"...why do we say that btw?
Agggg I forgot after thousands times my friends kindly tought me! Later!
-Japanese lyrics-
ウクレレみたいな たびをしよう
あるいていこう つきのかけらをひろいながら
ちずのかわりに キャンバス
にじのしずくで(そめましょう)
ひのでにまにあうように ぼやけたとけいはおいてこう
うみにためいき とかして
いしにこえをきざもう
つきをスープにうかべたら
ヒョウがらの くもがわらう
ukurere mitaina tabi wo shiyo
aruiteikou tsukinokakera wo hiroinagara
chizunokawarini canvas nijinoshizukude somemasyo
hinodenimaniauyoni boyaketatokeiha oiteikou
uminitameiki tokashite
ishinikoe wo kizamo
tsuki wo suupe ni ukabetara
hyougarano kumogawarau
-English Translation-
Hello there
Shall we travel just like a ukulele
Walk along as picking up pieces of the moon
Don't use maps Paint a canvas with drops from the rainbow
Just leave your blurred clock So we can make it to the sunrise
Your sigh will melt into the sea
Curve our voices to the stone
Put the moon to the soup glass
Leopard spotted clouds will smile
just fyi this lyrics version is actully for bonus in Japanese edition of Wario land 4.
Raining cats and dogs
http://www.loc.gov/rr/scitech/mysteries/rainingcats.html
↑ I looked into the link above and was said. "We don’t know."
The phrase might have its roots in Norse mythology, medieval superstitions, the obsolete word catadupe (waterfall), or dead animals in the streets of Britain being picked up by storm waters.
Why “cats and dogs”?
Again, we don’t know for certain. Etymologists—people who study the origins of words—have suggested a variety of mythological and literal explanations for why people say “it’s raining cats and dogs” to describe a heavy downpour.

Sore throat, Kaiji, The Colosseum in Rome etc...
10 Ways to Soothe a Sore Throat
It's horrible to spend all day with a sore throat, especially if you are working in a Customer service center or wherever you have to handle phone calls. These are some of the tips and remedies for a sore throat which I found amazing and easy to implement.
1. Salt gargling: gargling several times a day with warm salt water can reduce swelling in the throat and loosen mucus, helping to flush out irritants or bacteria.
2. Lozenges and sprays: Sucking on cough drops stimulates saliva production, which can help keep your throat moist.
3. Fluids: Staying hydrated is very important, especially when you're sick and your throat is irritated or inflamed
Kaiji: Ultimate Survivor
How can people see a mere tissue box as careful as Kaiji? "This box is great..."
Owww Kaiji is great, been so thrilled that I couldn't help but to watch 3 episodes.
I didn't like the style of this manga, especially Kaiji's pointy nose, but I got over it after a episode.
This anime is very well created but cannot be helped but feel hatred toward humans in general later.
Rome, Italy: The Colosseum
Here's one of the ways to tell if a person is a Jojo lover or not.
Ask a person "what do you imagine when given the word the Colosseum in Rome."
Ordinaries would say "Gladiator?" or "A man fighting against a lion."
Some will say "We are all sleeping slaves of fate..." ok it's Jojo fan.
I have been reading Jojo again (never boring) since Jojo All Star Battle is just around the corner.
One of my dreams is to translate all Jojo manga official into many languages.
This masterpiece cannot be kept only for Japanese but should be for every human beings.

German Measles, Sloppy Joes II and more...
Rubella, also known as German measles
http://wwwnc.cdc.gov/travel/notices/alert/rubella-japan
As of August 7, 2013, 13,509 rubella cases have been reported in Japan during 2013. Numbers of rubella cases have been highest in Osaka, Tokyo Metropolis and Kanagawa Prefectures. The peak period for rubella is spring to summer in Japan.
What is Rubella anyway?
Rubella, also called German measles, is a disease spread by the coughs and sneezes of infected people. Symptoms include rash and fever for 2 to 3 days. Some people do not feel sick. If a pregnant woman gets rubella virus, her baby could have birth defects such as deafness, cataracts, heart defects, mental disabilities, and organ damage.
It seems Rubella has been eliminated in the United States. People who cannot show that they were vaccinated as children and who have never had rubella should be vaccinated.
Sloppy Joes II
I made Sloppy Joes II for today's lunch, which my American friend recommended me.
It was quite easy to cook and prepare, took me only 10 mins. Here's a recipe and ingredients.
■Ingredients

That was good though I was feeling a little ill since visited hospital for German measles checkup.
It's a common food for Americans and mostly eaten with bread.
Underground vs. Overhead cabling
Power Line Installation-Cost Comparison and Mitigation
http://www.elp.com/articles/powergrid_international/print/volume-18/issue-2/features/underground-vs-overhead-power-line-installation-cost-comparison-.html
-Summary-
1. Overhead cable has risk of being destroyed by natural disasters or other reasons, which causes tangible and intangible impacts.
: There are also associated intangible impacts to a utility's customers such as despair, discomfort, anxiety and helplessness. And direct economic impacts to customers resulting from lost economic activity, food spoilage, looting, etc.
2. Underground cable is much safer but it takes higher cost to install and maintain underground lines.
[Cost Differentials] underground line costs 5 times more expensive than overhead line
[69 kV]
Overhead line - $285,000/mile
Underground line - $1.5million/mile
[138 kV]
Overhead line - $390,000/mile
Underground line - $2 million/mile
(without the terminals)
According to the May 2011 paper "Underground Electric Transmission Lines" published by the Public Service Commission of Wisconsin
What is PBX?
http://searchunifiedcommunications.techtarget.com/definition/private-branch-exchange
A PBX (private branch exchange) is a telephone system within an enterprise that switches calls between enterprise users on local lines while allowing all users to share a certain number of external phone lines. The main purpose of a PBX is to save the cost of requiring a line for each user to the telephone company's central office.
The PBX is owned and operated by the enterprise rather than the telephone company (which may be a supplier or service provider, however).

I'm Back with Kefir
Yeah I'm finally back with fury to keep this diary just to practice my writing skill.
Using English everyday in work, but I have no chance to write about non-business materials.
Also here is used just to keep my memo organized. also just for html command practice. Basically my playground. Lol
What is Kefir?
Kefir is a fermented milk product similar to yogurt, which originated in Russia. This tangy, creamy milk product is sometimes referred to as the “champaign of milk” because of its fizzy effervescence.
WHAT IS Kefir I said?
Kefir is made from milk that has been gently heated to eliminate possibly pathogenic bacteria...
http://foodreference.about.com/od/Dairy/a/What-Is-Kefir.htm
Raw Food Recipe: Making Kefir & Growing Water Kefir Grains
I wonder how much these Kefir grains are. This seems around Y700 for "5 packs."
I couldn't find any site which sells Kefir grains by the kilo.
Didn't know Kefir grows with honey sirup(sugar). If only I know how to make kefir grains from scratch...
The only reason why I featured Kefir today was I had this Kefir - Oogonto and found it really good.
It's available at Seven-eleven, or somewhere else.
wow, I didn't know I can arrange layouts for post as free as like this.
I just copied the picture on the right from the site and right-clicked → paste, and that was it! totally underestimated Blogger's easiness to organize the post. I like it.
WHAT IS the benefit of Kefir?
It seems to aid in digestion and calming an upset stomach. Kefir can also be mixed into smoothies, poured over cereal or granola, or used in baked goods.
Difference between Yogurt and Kefir
The most significant difference between Yogurt and Kefir is that only Kefir contains beneficial yeasts, which can also produce alcohol.
The bacteria in kefir, on the other hand, can actually colonize the intestinal tract. Kefir also contains a lot larger range of bacteria, as well as yeasts. So while yogurt may contain a handful of different strains of bacteria, kefir may contain many more than that.
