Idea of Music

Music is the sound form of words. The form can be expressed with tools. Either voice or instrument act as medium to communicate a meaning of the words put together. Different forms of music are formed based on the mankinds need to communicate with inside self and immitate it to outside. If there is rythum to communicate inside then the outword expressions are portrayed. The body of music is first defined to find a classical meaning and is an art form. Hence music doesn't belong or represent a relegion or a region. IT is universal. When there is melody going with harmony music can be explored from all directions. The frequency of this music form notes or swara. The 7 forms of swara called saptha sware Sa Re Ga Ma Pa Dha Ni is universal. The 5 variants apart of Sa & Pa add up to make 12 swara sthanas. Keyboard is a universal instrument which can depcit all the notes visually and help us make use of all the swara sthanas listed below. Veena is unique to carnatic music and sitar for Hindustanic, like the 2 forms of oldest musics started in 12th century.

1. Sa
2. R₁
3. R₂

5. G₂
6. M₁
7. M₂
8. Pa
9. D₁

Color and sound both are continum. So it is not required to give a name to each color or a sound. But from a human understanding it is required to break this continum. There comes tones in sound. The tonic defines a prescription in each much type. The pitch that defines this difference can't be controlled so is a natural scale does fits the music. Thus a music composed can be sung in any pitch based on the tonic assinged by the singer. Having had this fudamentals next step woudl be rAga.

Thriving with times

This is an excerpt while discussion on how to thrive with times. Saleema JS & Lakshmi Iyer started the discussion on how to understand what is time? It is just a duration or all the events in that duration ? Example duration is equal to 1 hr - 60 mins - 60 secs. Events in the duration are the ability as a society to produce, transmit and consume within the available duration. With technology and progress we are able to remove friction and able to fit more events in the duration. When the speed is related to time, so do the economy of speed is experiencing time as a faster change, resulting in volatility in sapce vs ambiguity. That is more complex, uncertain and anxiety creating fear. Once hope is bought it fear disappers. This further can be understood by introducing the : => modulus operator for treating uncertainty (variance -sigma) as your friend rather than doing a total quality is reducing that sigma. Thus hope becomes a friend and fear disappears. The value system built on abundance is not on what you know but what you can learn; learning and knowing. If knowledge = k ; rate of change of learning=dk/dt. How is the learning measure, may be the growth mindset is a word that defines this measurement? Experimentations over expertise will answer the knowing factor which is further agumented by sharing. Through interaction over intellectual property one can spread this learning as entropy in abundance. Lakshmi Iyer summed it up as “Embracing uncertainty leads to better learning through experience over time”

Pre-overview: Distributed, Grid, Cluster, Utility & CC

CC -> Defintion, Characteristics ( on demand, Broad network, Resource pool,Measured servic, Rapid Elasticity), Common Charactersitcs( Massice Scale, Resilient, Homegeneity, Geographic distribution, Virtualization, Service Orientation, Low cost s/w, Advanced Security)

CC service Models -> SaaS, IaaS, PaaS

Tpes of Cloud (Deployment models) - > private, community, public, Hybrid

Cloud & Virutatilzation -> Cloud Sourcing - > Storage (Eg: Amazon-EC2 & S3)->Adv&disadv->3 main Reasons still to go r cost, capacity illusion, low utlization in private

IaaS Economics -> Purchase cost, cost/hr for 3yrs can get the cost ratio for cloud/inhouse= Efficiency, cost/hour,power/coiling, mgmt cost give total cost/effective hr as Costratio inhouse/cloud

Benefits of 1. Public., 2. for Small&Medicum businesses, 3. Private

Economics of Paas vs IaaS -> IaaS for servers, PaaS for web appication

PaaS benefits, SaaS benefits , Benefits as perceived by IT, Factors for investment(cost, fexibility and scalability main reasons)

Purpose of CC in organizations:

NPTEL- CC - Week 0

IP datagram -> Header Fields -> Time to Live(TTL)-> Is used to prvent packet looping

Process sate transitions for preemptive scheduling-> a running process can move to ready state, a ready process can move to ready

state, a blocked process can move to ready sate.

System calls in sending SYN packets->connect

Hosts per subnet?

System with 3 processes that has 4 instances of same resource type. Each process request max k intances..deadlock question
