Site Reliability Engineering or DevOps Changing Digital Economy July 18, 2017

Gone are the days of long term planning in software development and delivering value to core businesses. Data science based analytics facilitates to generate the real time data, funnel the bottlenecks observed in the development processes. With evolution of agile based development processes rapid feedback of the development strategy is decided fast as fail fast and fail safe. Site Reliability Engineering practices adopts the incremental feedback approach to quickly improve the software delivery pipeline through established continuous integration,  continuous delivery and continuous deployment pipeline.

It helps to streamline the pyramid to keep the People over Processes and processes over Tools. Agile and Lean start up development methodology highlights the gaps where an organization is inefficient to deliver the quality software to its clients and customers, it helps to quickly redesign the strategies focused towards quality software delivery pipeline.

A thought leadership change is evolving through this period which helps companies to relatively invest in hiring best minds who can understand the business needs and align the engineering priorities, identify gaps in the development, operations and security processes by thriving on data based incremental implementation approaches.

 

Start up Companies like Rapyuta & Teralytics are leveraging the DevSecOps practices to build the Highly available cloud Platform product to support data science based engineering.

How to write a monthly report for your investors or manager September 9, 2015

Awesome article to get insights into Financial of start up ecosystem.

A Founder's Notebook

Edited excerpt from Why communicate more with your existing investors (and how to do it efficiently) by Armandi Biondi:

There are two key benefits to sending your investors a monthly recap: a) you’ll give them a broad-enough but meaningful-enough perspective on what’s happening, b) you’ll give yourself a forcing function to generate relevant results in a reasonable amount of time. Here’s how:

• Short & sweet always win.
• Be numbers-oriented. How did your key metrics perform compared to the last month figure and the overall total? Where do you expect to go a month and a quarter from now? Those are the only things that matter.
• Think actionable. Write about what you did and how it generated impact on the company, and what you’re going to focus on in the next 4 weeks.
• Design matters. Use bullet points, divide the topics by area (I use five: product/tech, sales/clients, funds/corporate, press/pr, team/hr), leave some…

First page Advertisements: Surprise and Surmise of Journalism August 11, 2015

Front Paper News Headlines were used to be an element of surprise and surmise. Gone are the days when over a cup of tea and coffee we used to wait eagerly for news papers, spend time with family members, children and elders. Discussing with them politics, market, society, crime, neighbor hood gossips. The good old days, nostalgic memories are hard to revive back. The charm of reading headlines have gone due to the paradigm shift in printing full front page advertisements instead of “positive” front page headlines. Morality journalism address have been shifted to the graveyard, What rules now is paid media journalism, crony capitalism, political affinity and how we can forget advertisements. If we go by stats, In my view approximate 60% of print area of news paper is covered with  Advertisement where e-commerce firms, political parties, corporate agenda and meager space left for citizen welfare, government schemes. Standard Journalism is left only with few editorials being published, these editorials shapes the thoughts, actions and view points of our youth but this space is crowned with trust deficit. Its absolutely flabbergasting to observe how news paper purpose has shifted from telling, spreading effective news to informing about products through advertisements. News Papers rules the print media space, If this lobby have good intention to shape our youth minds with positive news content, value system then it would be absolutely wonderful of finding our youth, children and adult in creating community value system. But the shame reality is from what I observe I don’t see this happening, not now nor in near future. On certain occasion I was privileged to get access to polyglot news papers from Japan, Israel, South Korea, Singapore, US, Canada and India. The biggest trend I observed  in terms of the charm of reading front page headlines , Indian news papers are filled with hate, violence, critical voice and notes, meaningless statistics, where as Front page of mentioned countries were mind boggling, to start with content which is positive in nature, Imagine reading positive content, the power of positive thoughts{Reading is the food for thought, Which means good reading good thoughts, Bad reading, Bad thoughts} shape and set your day  on positive line. Hatred, violence, lobbying is given page 2/3 status. Art, culture, language, Humanity, Science, Technology  & Engineering makes lots of positive news but only once in a while these content is given a space on front page.    

Pot-Shots: FlipKart vs SnapDeal

With  market sentiments moving from pure social economy towards consumerism which is central to capitalist market, free market and free trade policy. This is good for Industries particularly Infrastructure, Telecom, e-commerce and manufacturing, But absolutely bad for farmer, people with low disposable incomes.

In the whole pyramid farmer should be put first but this is unfortunate in India and other developing countries we put our farmers at the bottom of pyramid. At the end we have to eat food, when there is no producer of food then what is the meaning of education, Land, economy, These all word cloud becomes  meaningless, shaking altogether the unwavering and unparalleled faith of 7 billion people of humanity just to satisfy the need of scores of people with high income, These 4% of population high net worth individuals controls the more than 90% of world’s total money. I wish there should be more equitable economic, macroeconomic financial models should be invented/evolved by concerned well learned economists, bureaucrats, politicians, Ambassadors, Intellectual thinkers, entrepreneurs. It will be absolutely wonderful to see observe the getting faith of 7 billion people restored with news papers as an agent of change by inculcating the power of news content positive in nature, building the value system of our citizens in general and children, youth in particular. Value system is central to build the self belief at the level of individual, community, patriotic citizens and nation. News paper have lion’s shares in print media, it should think about creating positive ecosystem by putting sovereignty over self interest profits in creating mark among the people.

Respect for Teaching Community in India: Falling Standards January 19, 2015

I would like to say this in the words of newly recruited professor Mr. Brijesh Kumar { http://brijeshkumar.com/ }

Ah, how the times have changed. One of the IIT Bombay students just said to me on Quora, that you are just an assistant professor because you could get nothing else. It is just not that one person, this thinking is quite representative of how many other students in IIT think. Alas, how the times have changed?
It was not very long ago, that I was studying in IIT Delhi. I never heard a single student speak like this about a teacher during my four years of stay there. “He is JUST an assistant professor.” I graduated about 7 years ago and so much change. Such disrespect amongst the students towards their teachers.

Let us say that even if the premise were true, that he could not get anything else other than a professor position at IIT, what can you learn from him, if you have that attitude towards your professor. And, you may think it is trivial to get a position as assistant professor at IIT, believe me it is not that easy. Every year, departments get applications in 100s and only 1 or 2 get selected. But, this is besides the point that I am trying to make. If you want to learn something, there should a basic level of respect towards the teacher and if there is a feeling of contempt, you can learn nothing from the teacher.

Falling Standards of Education and Respect for Teachers as well

My feeling about this change in attitude of students in recent years is because the students no longer come to IITs to study, they come to get their fat pay packages. They are so shallow that they count everything in terms of money. They have no higher purpose in life other than to make money. I don’t know why IITs promote the pay packages in newspapers, all it does is increase the intake of such low quality students in IITs, who have nothing other than money making in their minds.

In all honesty, running after money is not very glorious. Unfortunately, our society is running after money and anyone who does not do that is considered a loser. I am one such loser. I am JUST an assistant professor.

Cost effective wireless Sensors for Structural Health Monitoring August 31, 2010

Cost effective wireless Sensors for Structural Health Monitoring

 

Monitoring the performance of civil structures calls for an immediate attention. Current commercial monitoring systems suffer from various technological and economic limitations that prevent their widespread adoption. The extensive wiring used to route measurements from system sensors to the centralized data server represent one of the greatest limitations.

The low cost wireless communications appears to be the best alternative, resulting in the design of a prototype wireless sensing unit. A more intelligent incorporation in the wireless sensing unit would be the use of microcontrollers for computational power.

 

Approach:

 

The architectural design of the wireless sensing unit, as shown in Figure, is divided into three major subsystems: sensor interface, computational core, and wireless communications.

How to Connect N70 and Motorola L series (L7 & L9) sets In Ubuntu October 25, 2008

Follow these steps to connect to Airtel GPRS or other Company GPRS :

1. Connect the phone to the PC/laptop.
2. Run wvdialconf command from the terminal which creates a
configuration file for wvdial
3. Open /etc/wvdial.conf and add the following commands:

Init3 = AT+CGDCONT=1, “IP”, “airtelgprs.com”

for other Networks : aka “companynamegprs.com”

4. Check for other settings it should be similar to values given below

ISDN = 0
New PPPD = yes
Phone = *99***1#
Modem = /dev/ttyACM0
Username = a
Password = a
Baud = 9600

Username /password may change for you. The modem device also may change.

5. Now type wvdial from the terminal and the GPRS should be connected

It works for me but with the Motorola L9 . It should work for you with
Nokia N70 too. Let me know if you face any problem.

Howto: Tweak and maximize your bandwidth in Linux via sysctl! September 16, 2008

Here I will unleash a few hidden settings that should improve your internet speed, and work with all current linux operating systems including Ubuntu:

1. Open a Terminal via Applications->Accessories->Terminal

Type:

    sudo vim /etc/sysctl.conf    (press i for edit mode)

Then Paste the Following at the end of the file:

 ## increase TCP max buffer size setable using setsockopt()
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216
 ## increase Linux autotuning TCP buffer limits
 ## min, default, and max number of bytes to use
 ## set max to at least 4MB, or higher if you use very high BDP paths
net.ipv4.tcp_rmem = 4096 87380 16777216
net.ipv4.tcp_wmem = 4096 65536 16777216
 ## don't cache ssthresh from previous connection
net.ipv4.tcp_no_metrics_save = 1
net.ipv4.tcp_moderate_rcvbuf = 1
 ## recommended to increase this for 1000 BT or higher
net.core.netdev_max_backlog = 2500
 ## for 10 GigE, use this, uncomment below
 ## net.core.netdev_max_backlog = 30000
 ## Turn off timestamps if you're on a gigabit or very busy network
 ## Having it off is one less thing the IP stack needs to work on
 ## net.ipv4.tcp_timestamps = 0
 ## disable tcp selective acknowledgements.
net.ipv4.tcp_sack = 0
 ##enable window scaling
net.ipv4.tcp_window_scaling = 1

Type :wq to exit and save.

Type in terminal

    sudo sysctl -p

to apply the settings.
You can disable all these settings by removing these lines you added via:

    sudo gedit /etc/sysctl.conf
