DNS Resolution in PERL

DNS Resolver in Perl DNS, which stands for domain name system, controls your domain name's website and email settings. When visitors go to your domain name, its DNS settings control which company's server it reaches out to. Benefits of DNS: Domain Names are alphabetic, they're easier to remember. Capable of providing security. Companies that make use of DNS server are able to protect the company related data from being accessed by unwanted people. DNS servers are quite flexible to use. A single DNS server is capable of managing multiple Internet sub domains and domains. How DNS resolver... Read More

Basics of Restructuring and Refactoring

The code that seems clean and fresh today, will someday begin to smell... Thats when you rewrite it!!! WHAT IS IT? A passionate developer always tries to write clean and quality code. Contrary to that, we often find messy and unstructured code. The transformation from a clean code to a messy code is a natural process where the code 'ages' with time. With time the code gets modified by the same or a different programmer. These later additions to the code are primarily tweaks and fixes. These additions often do not fit with the existing code design and thus are placed with less emphasis... Read More

How we converted Latin1 encoding to UTF8 in Mysql DB

The problem statement of converting latin 1 encoding to UTF-8 encoding in mysql  database is something similar to upgrading your linguistic skills from english to any other language in the world. Sounds impractical!! Correct, you may find it difficult to learn all the languages in the world as it is practically impossible to learn the rules of so many languages. But machines can do it easily. You just need to feed it with character set of that language and rules i.e. in technical term collation. We at naukrigulf deal with middle east countries so our system needs to understand ARABIC...

Speeding up writing Unit Tests

Unit Tests writing, contrary to popular coding humour, is an important aspect of the development process. The process of writing Unit Tests reveals setbacks in one's code. It helps us identify complicated logic, magical functions, magic inside functions and non testable pieces of code (ex: - an if condition which is impossible to execute). Most of the programmers find writing Unit Tests tedious and cumbersome. But at Naukri we transform it into a fun way of learning more about the code base we are working on. Creating a test file is initially a repetitive process. It involves... Read More

Automating Front-End Processes – The Jenkins way

Being an IT techie, we are highly concerned with the way our websites are being developed and the way they perform. We are constantly pushing our limits to build and deliver high performance products and hence take up the end-users’ experience to another level and we do this by following countless techniques and technologies. In order to achieve the above said, we have a long list of tasks and processes we need to do or follow and the pain point is that most of them are taken care of and done manually. Before diving deep into the ways of doing all the stuff, lets first have a look at... Read More

Agile : Iteration Planning

Epic, Feature, Story. “A goal without a plan is just a wish” — Antoine de Saint-Exupery Agile, It’s all about flexibility in the course of software development phase. But flexibility is not possible without a proper plan in place. Even when we decide the architecture of a software, we often keep in mind that the software stays flexible to any changes in future and therefore design patterns come into picture. There comes Iteration,  a step by step approach. Grab yourself a cup of coffee as we are going to dig deeper into it. Planning plays a vital role in the software development life cycle. It...

Database Backups Using MySQL-ZRM

Data is one of the biggest assets for any organization, so maintaining multiple copies of updated data and to make it available in case of any hardware/software failure is a key thing to keep the business running. Thus, an efficient data backup solution is a must. Taking backups of huge data is always a challenge because having a hot backup of TBs of data is impossible and backing up the complete filesystem doesn’t guarantee data consistency. While exploring different open source backup solutions, we came across MySQL-ZRM (MySQL Zmanda Recovery Manager) which matched our requirements to an... Read More

Info Edge (India) Ltd, now IPv6 ready for all portals

What is IPV6? IPv6 was developed by the Internet Engineering Task Force (IETF) to deal with the long-anticipated IPv4 address exhaustion. IPv6 is intended to replace IPv4. This new version of the protocol serves the same functions as IPv4 except, it does this without the same limitations as of IPv4. IPv6 Address vs IPv4 Address IPv6 IPv4  Address length  128 bit 32 bit  No. of IP Address  2128 232  Address  representation  8 groups of 4 hexadecimal digits Four numbers whose value range from 0 to...

Naukri Mobile application now supports offline mode

The Mobile phone network in India though claims to have 4G but in reality the reliability and speed of the network is yet to reach and span whole India. Even in metro cities the continuity of the network is not perfect. In such scenarios it became a technical challenge for the mobile app engineering team to come-up with solution that allows app users to use the app without worrying about network signal strength or availability. Naukri IOS mobile application has a new offline feature that supports apply to jobs and edit of profile. The job seekers using the Naukri app can apply to cache jobs... Read More

Import resumes by bulk upload

Recruiters generally collect lot of resumes from email or from many other recruiting software. Over a period of time they have lots of resume stored as individual files or in compressed format. It becomes nearly impossible to look for a candidate from the huge collection of resumes stored at multiple places in multiple formats. Career Site Manager (CSM) is the one stop solution for application tracking which includes the capability to handle such scenarios and make it easier for recruiters to store resumes and search for relevant candidates. Rather than painstakingly uploading all your... Read More
