Now that you have developed your application using Angular 2.x. The next important step would be to limit access to certain routes. In other words, whenever user tries to navigates to a route, your application needs to decide whether or not to allow navigation. This is where "Angular Route Guards" come into picture. Angular exposes few interfaces which can help with this decision. This medium post by Ryan Chenkie explains in detail about the 5 different types of guards offered by Angular: CanActivate CanActivateChild CanDeactivate CanLoad Resolve These interfaces return a boolean indicating whether or not navigation to a route should be allowed. linkTo: https://medium.com/@ryanchenkie_40935/angular-authentication-using-route-guards-bf7a4ca13ae3

Narikurava is an indigenous hunting tribal community in India, concentrated more in the state of Tamilnadu. They live a nomadic life. Dr.Philo Irudhayanth has done extensive research on this and other nomadic communities in India. His notable Tamil book on the Narikurava community titled "Yaar intha Nadodigal"(translated into 'Who are these nomads?') provides an extensive record of their life, culture and customs. Related articles from The Times of India, that might be useful for anthropologists: 1. Tracing a nomadic dialect from TN to Gujarat 2. Rituals reflect distinct culture of Narikuravas
Late Dr.Philo Irudhayanath. He has written about 63 books and 5000 articles on tribals of India, 67 magazines, in English and Tamil. He was the recipient of National Award(India) in 28-April-1975 and Tamilnadu state award and UNESCO award for his extensive research works on the tribes in India. Born in Mysore in 1916, Dr.Philo Irudhayanath, as a school teacher for 25 years during British India, toured the whole of India with/in his bicycle and researched about the tribes of India, from Tibet in the north to the Nilgiris in the south. Out of the 63 books he has written, only 37 have been published so far and I was able to collect only 6 of them from Vaanathi Pathipagam chennai. Through the efforts of respectful sir N.Rathnavel , I was…
Is Kangaroo a native of India? "Yes" says Dr.Philo Irudhayanath in his Tamil book in 1985 named "காட்டில் கண்ட மர்மம் (Mysteries I have seen in forests)". Cave drawings by the early man in the "Satpura Caves" contain images of the present day Kangaroo. This book goes on to say that for some reason Kangaroos, which originated in India, migrated to Australia. The language spoken by the Australian Aborigines bear a strong resemblance to the South Indian Language: Tamil.
"In India, if you analyse where tribes are concentrated, you can observe that they are commonly found around places where several wars were fought during the ancient times. For eg, foothills of Himalayas, Madhya Pradesh, Gujarat, Orissa, Assam, Vindhya mountains, Malabar regions, East West mountain ranges." This is one of the interesting fact from the research book of Dr.Philo Irudhayanath, titled in Tamil "Kaatil Kanda Marmam", published in 1985.
*நாய் தேனை நக்காது. *சுத்தமான தேனைக் கண்டால் நாய் ஓடிவிடும். A dog never licks honey. It would run away if it comes in contact with pure honey. *கரடி மரம் ஏறி தேன் கூட்டை உடைத்து தேனைக் குடிக்கும். குடித்தபின் போதை உண்டாகி மரத்தின் மேலிருந்து அப்படியே பந்துபோல சுருண்டு கீழே, "தொப்" என்று விழும். Tempted by honey, a bear would take all risks to climb a tree, consume it and then intoxicated it falls down with a "thud". தேன் குடித்த போதையில் இருக்கும் கரடியை அடித்துக் கொல்வது மிகவும் சுலபம். It is said that it is easy to kill a bear intoxicated by honey. இன்னும் சுவாரசியமான நேரடி ஆய்வுகள், மறைந்த டாக்டர்.பிலோ இருதயநாத் 1980களில் எழுதிய ஆராய்ச்சி நூலான "காட்டில் கண்ட மர்மம்" நூலில் இருந்து.

An unquenchable thirst for reading books drove me to the great Connemara Library at Egmore, on 28th September,2013. I usually hang around the history section trying to pick up some interesting books on people, both common and extraordinary, in the pre-independence period. This time I noticed that section contained books on a mix of categories: Computers, History, Biographies, Literature. It may have been the mistake of the librarian or a purposeful assortment of varieties. Whatever it is, as usual I picked up some armful of bulky books planning to skim and sip through whatever tastes good in all of them. Then, there was one particular book which attracted me the most: “E-commerce Logistics and Fulfillment, by Deborah.L.Bayles”. There were 2 things, in the first place, that attracted me to this…
Source of this article: MOHIT’S DEN The three main techniques to analyze the behavior of wired and wireless networks are: Analytical Modeling, Computer Simulations and Real Time Physical Measurements. Analytical Modeling is very tedious and Real Time Physical Measurements may not be possible all the time. Computer Simulation is the only feasible approach to the quantitative analysis of networks. Computer Simulations can be Discrete Event Simulations (e.g.: arrival and departure of customers in a bank) or Continuous Simulations (e.g.: waterflow in a mountain). Computer Simulations are generally Discrete Event Simulations. Network Simulator – 2 (NS-2) is a discrete event and packet level simulator developed at UC Berkeley to analyze the performance of wired and wireless networks. The architecture of NS-2 is composed of five components:: Event Scheduler (there are four: List,…
