Understanding the Nipah Virus Outbreak in KeralaUnderstanding the Nipah Virus Outbreak in Kerala

September 15, 2023| rajinfo| 0 Comment | 10:13 pm

The Nipah virus has once again made headlines, this time with an outbreak in the southern state of Kerala, India. First identified in 1999 in Malaysia, the Nipah virus belongs to the family of Paramyxoviridae. It is a zoonotic virus, meaning it can be transmitted from animals to humans. The natural hosts of the virus are fruit bats, specifically the Pteropus genus.

The recent outbreak in Kerala has raised concerns due to the high fatality rate associated with the Nipah virus. The symptoms of the infection include fever, headache, dizziness, and respiratory distress. In severe cases, it can lead to encephalitis, an inflammation of the brain, which can be fatal.

The outbreak in Kerala is believed to have originated from a family who consumed contaminated fruit juice made from fruits that had been partially eaten by infected fruit bats. The virus can also be transmitted through direct contact with infected animals or their bodily fluids. As a precautionary measure, the affected areas have been put under strict quarantine, and health authorities are closely monitoring the situation.

what is HSTS protocol?what is HSTS protocol?

November 28, 2020| rajinfo| 0 Comment | 11:56 pm

HSTS, or HTTP Strict Transport security header(Strict-Transport-Security) is set on your domain, a browser will do all requests to your site over https from then onwards. In case when a hacker is redirecting this user to a fake domain.com, the browser remembers to use SSL because of the HSTS, so requests the secure site.

Browser needs to visit your site first to see this header, this will be active only after the first visit.

Why HSTS?

You can set SSL certificate on your domain, anyone can still use your site over http. The simplest solution is to add a redirect to your site and forces it over SSL. But user is open to attacks when the hackers directs the request to a site pretending to be non secured domain.

Microservices are built with REST APIs, and the significant reason is that they help in building loosely coupled services. Spring Boot provides the flexibility to create REST APIs quickly, which are exposed as various services.

Spring Boot Framework is quite flexible while working with SQL database. You can use direct JDBC calls using JDBC templates, or you can go by implementing hibernate. One more significant option that Spring framework offers is by creating repositories for Spring Data implementation

Spring Boot provides an option of an embedded in-memory database. This has no persistent data storage. You can retain the data as long as the application is up and running.

Steps to build a simple Spring boot application:

Generate a quick Java project with Maven command.
Update pom.xml with the Spring web and other Spring boot dependencies.
Add SpringApplication.run() method to bootstrap Spring application.
Do a Maven clean build using mvn clean package command.
Execute command mvn spring-boot:run to run the application.

<dependency>
<groupid>org.springframework.boot</groupid>
<artifactid>spring-boot-starter-data-jpa</artifactid>
</dependency>

<dependency>
  <groupid>org.hsqldb</groupid>
  <artifactid>hsqldb</artifactid>

Do you Need SSL(https) for the Website?Do you Need SSL(https) for the Website?

What happen’s if you don’t have the SSL?

If the SSL certificate gets flagged as invalid by the browser, the data exchanged between you and the website you’re trying to connect to will be transferred in cleartext. Potentially, any user credentials or other sensitive data communicated over the channel can be sniffed or stolen. It is always recommended not to proceed over an insecure connection.
The user’s visiting your website will lose trust due to a lack of perceivable credibility.
Some users might be convinced that you are hosting a malicious website and would choose to steer clear even after the issue gets fixed.
Adversely impacts business and brings down the reputation especially if you are not a known player experiencing a temporary technical glitch.

The intention behind having an SSL/TLS certificate was not just for authentication but also to establish the identity of the remote server with whom the client browser communicates.

SSL /TLS protocol to ensure that data travels securely over the wire. Encrypting data in transit helps to prevent any malicious user from sniffing the network to steal sensitive information like passwords, credit card details, etc.

SSL or Secure Sockets Layer and TLS (Transport Layer Security) are cryptographic protocols designed to provide a secure communication channel between clients and servers over the internet. TLS is the relatively newer version when compared to SSL, SSL is the older encryption protocol.

New Law Passed Jallikattu WinsNew Law Passed Jallikattu Wins

Young Indians Saving Jallikattu

The much awaited the Law for Jallikattu Was Passed. This is the huge victory for students #StudentsPower. Proud Movement for all. Unity wins. Jallikattus are big events that draw people in thousands. They generate a lot of consumption around them which is significant for the rural poor.

Why Jallikattu?

Supporters of native breeds argue that foreign breeds might not be a better option in the long run. Native breeds require less expensive maintenance and are less vulnerable to diseases and viruses. Jersey cows also require more grazing pastures. In the long run, native breeds are a better economic option. And Jallikattu is one big way people keep on rearing native cattle.

Artificial insemination, where semen from one bull can impregnate scores of cows, is criticized because it is believed to destroy the genetic diversity of cattle. It makes cattle more vulnerable to viruses and diseases. The supporters of native breeds argue that this has led to foreign companies creating monopoly on semen.

The low-yield milk of native cows can generate a huge demand as increasingly people perceive it to be more nutritious.
