The ‘Interview’….

Several years ago, a young lady wearing a salwar kameez, walked into a quiet place in a hesitant way. The environment was fairly formal and the people in the place made her feel quite warm and comfortable. This was the first time she was meeting them.

Her father had already hinted that this might not be the usual type of conversation. After the initial formalities, the conversation shifted its focus towards the real reason why she was there.

The interview process:

She was working in a computer training center then and the leading person in the situation asked a few questions along  these lines:

  1. “What computer language had she studied while she was in college?”
  2. ” What computer language did she teach now?”
  3.  “Was the concept of pointers in ‘C’ really hard?”

If you think, this was a technical interview, think again!

     There were also other non-technical questions such as:

  1. “Why was she not wearing any gold bangles – did she not like jewellery?”(all from first impression! :))(True – She had never liked gold jewellery!)
  2. “How would she like her future husband to be?”
  3. “Did she like to have an arranged marriage or love marriage?”

   I am not sure whether you are able to figure out the lead questioner in the above conversation…. it was a would-be father-in-law and a would-be daughter-in-law having a conversation! 🙂

 

 

 

How did it happen?

Contrary to most other ways of getting married in India, this couple got married in a novel way. The parents, sister and the girl were called for an appointment to meet the prospective groom’s family! By a strange turn of events, they marched right into their house without thinking twice(normally, it is the groom’s family that marches into the girls house!)  The would-be father-in law, mother-in-law and the groom’s grand mother were all present and the casual interview began!! 🙂

Only one obvious  person asked the questions – while the two other members remained silent. A person of excellent mathematical and computer skills, it was not easy to get past the would-be father-in-law’s questioning. Word had it that he could crack integration problems with ease even at his age!

Most of the questions that he asked(like love/arranged marriage etc and the many technical computer questions absolutely threw the girl off! – who would go for a wedding discussion and answer questions about pointers in ‘C’?!! :)) It was the frankness and outspokenness of the father-in-law and the girl’s ability to answer them boldly that really sealed the interview. 

The girl did crack the interview because she did marry the boy just a few months later! 🙂

And no prizes for trying to identify the characters in the above story! 🙂

The ‘Apple’ of my eye! :)

For most of the Apple lovers possessing iPhones, iPods, Mac books and iPad and so on, this week was an exciting week as it saw the  launch of the iPhone 8, iPhone 8S and iPhone X. How will the new iPhone X be? Pronounced iPhone ’10’ and not iPhone ‘X’, this is the thought for most of the world(if not all!) Till we can lay our hands on it or see someone who lays their hands on it 🙂 we can only surmise a few details as of now:

Features of iPhone XDescription

The most interesting features of the iPhone X  are:

  1. Price – $999 for US markets and a cool lakh for Indian markets(256GB variants)
  2. Processor speed – The iPhone X has the A11 Bionic chip supposedly the most powerful and smartest chip
  3. Battery life – The iPhone X boasts of 14 hrs of Internet usage which will be tested in due time(Scientific American)
  4. Camera – It has a larger and faster megapixel sensor(for camera buffs and geeks, there is plenty in store with the new iPhone X to achieve superior quality pictures) 
  5. Face ID – This is obviously the most talked about authentication feature of the new iPhone X – ‘face recognition’. Apple has done away with the home button and introduced the ‘face recognition’ feature which raises interesting and new questions. While biometrics is always a better way of authenticating a user than the traditional username and password combination(not to forget remembering the umpteen number of passwords) face ID might be much more trickier than  other biometrics.  These are some of the key points regarding Face ID:
  •   For now, only one face ID will be supported per device.
  •   Going by the number of thoughts around the web, what if the device can be unlocked while sleeping or by an identical twin?

           iPhone user experience is always beautiful and in India where owning an iPhone(or any Apple product and any version) is a symbol of pride, it remains to be seen if the new iPhone X will live up to its standards. Most of the details and doubts will only be solved in due course of time – but one final question that is on everyone’s mind – is it too pricey even by Apple standards?

Thanks to Satish for his thoughts, suggestions and tips for this post!

Should I or shouldn’t I?

After having written about the ‘Beauty of life in India’    and the reasons why we returned to India, I thought it would be a good idea to put the reverse into perspective too.

Most of the students in colleges all across in India (undergraduate or post graduate education) are always wondering the same thing throughout their education – “Should I go abroad for higher education/career option or not?” This has been an age old dilemma for those in their early 20s. They see their friends and seniors make the decision and they wonder if they should also pursue the same opportunity too. Some are able to make the decision quickly and have everything beautifully crafted out. They have written their GRE, GMAT, TOEFL and have their college admissions,scholarships, assistantships,visas  and financial details neatly ironed out.  Still others, might have offer letters and visas from prospective companies in their hand with great joy! 

For others, it is still a very confusing decision. While new lands seem to hold promising new opportunities, one is still not able to come to a concrete decision. Of course, while the decision is entirely yours and yours alone, some of my personal thoughts on this:

  1. It is fun to travel and see new places! 🙂
  2. It is always to good to explore new opportunities(education, career) particularly in the 20s with new educational institutions and employers
  3. Travel does broaden one’s horizons and we do get to know the different viewpoints in different continents
  4. We become more “family independent” (all said and done – staying within one’s family circle in one’s own country makes us all dependent on each other)
  5. We understand the meaning of financial independence too(managing finances in a foreign country where the cost of things is exactly the reverse of the home country is interesting! :))
  6. It is nice to experience the cutting edge technology of most things
  7. We also get to meet new friends, new food, new festivals, new experiences!(what is not to like?! :))
  8. And last but not least, every experience enhances us and better not let an opportunity to travel abroad slip by!

But given the chance and opportunity and everything else is fine and the stars are perfectly aligned for a stint abroad, do it today! 🙂 You will enjoy the experience…. 🙂

On a side note, I am sure there are plenty of other reasons like health conditions of family members or financial constraints or any other reason for one to not move abroad. 

Again my two cents thought on the topic! 😉

Which is more secure: SSL, TLS or HTTPS

Data that is passed “as-is”(without encryption) is prone to attacks by hackers and people with malicious intent. In order to pass critical financial information without being eavesdropped, it is crucial to encrypt all data. Encrypting communication allows one to pass credit card numbers, banking information and other sensitive details between the client and server and it is more secure. Encryption between the client and server is done by SSL/TLS. Before seeing which is a more secure protocol,we will first understand the terms SSL,  TLS  and HTTPS.

SSL is ‘Secure Sockets Layer‘ and it is used to secure the connection between the client and server. It makes use of public key encryption(when a public key may be used encrypt and private key may be used to decrypt –  or it can work the other way around too) and it works at the transport layer of the OSI model. It provides data integrity, confidentiality for the connections between the client and server. 

 

 SSL is now known as TLS or ‘Transport layer security‘. It is again a cryptographic protocol that is used to encrypt all communication between client and server. SSL 3.0 officially became TLS and TLS 1.2 is the latest version.  TLS is backward compatible to secure older SSL connections. 

‘HTTPS’ is ‘Hyper text transfer protocol secure’. HTTP is the building block of the Internet. HTTPis ‘HTTP’ secured with SSL/TLS.  HTTPS is synonymous with security during transmission.  Connections can be understood to be encrypted by seeing the padlock at the left hand corner of the screen or by seeing ‘https’ instead of ‘http’.

Now coming to the original question of which is more secure TLS is more secure as SSL has given way to TLS. But since communication security is still understood as SSL, it can be said that SSL/TLS is more secure.

Have you heard about cyber diplomacy?

‘Diplomacy’ is defined as “the art of dealing with people in a sensitive and tactful way” and cyber diplomacy is a careful extension to that.

Social media is an absolute necessity for individuals, businesses and government organizations. Most major heads of state are present either on Facebook, Twitter and/or other social media platforms. Given the openness of social media platforms, interactions are easy at all levels with these social media channels.  It is also easy for heads of state to carry out conversations with each other and/or with ordinary citizens.

Magic of ‘Belur’!

I have always been a fan of history and particularly Indian history. India is a glorious and old country with a rich heritage. There are numerous temples and other architectural monuments all around the country which are several hundred years old. While I have never had the opportunity to visit the monuments in the Northern part of India, the temples at Hampi, Halebidu and Belur(in the southern part of India) hold a special place in my heart. Words and pictures do poor justice to the exotic monuments.Join me as I try to recreate the magic of  ‘Belur’ in this post.

Definition of the day: Honeypots

“Honeypots” in network security is a computer system which entices hackers to attack it.  All ports are kept open on the  system and the computer acts normally with its services(but in reality, it is isolated and monitored) The main idea behind setting up “honeypots” is used to study the motives of malicious individuals and track their actions.

 

 

It must be noted that none of the production systems are connected to the “honeypot” system and no vital business information is lost during the “honeypot” project.

Introduction to Bitcoins

Even as the Bitcoin fork is making news, and there is  “Bitcoin” and  “Bitcoin cash” now, we will deal with the elementary aspects of “Bitcoin” and “Blockchain” in this post.

“Bitcoin” first appeared in 2009, but they are much more prominent now, thanks be to better adoption by individuals and professionals. In this post, we will understand the meaning of the “Bitcoin” cryptocurrency, some basic terms related to it and the way it works.

Definitions: What is “Deep web?”

Coming close on the heels of my previous post –  “Dark web“, we will be defining “Deep web” in this blog post.  Similar to “Dark web, the “Deep web” cannot be searched by traditional search engines as well. So, what is present in this “Deep web”, which sounds so similar to “Dark web”?  Here are a few features of the “Deep web”:

1. They cannot be indexed by popular search engines as well.

2.  The “Deep web” has content that you do not want everyone to see. The “Deep web” contents are:bank account statements,  contents of your email , medical information, academic information, databases and any dynamically generated information.

While “Dark web” is associated with illegal content, “Deep web” does not have that connotation.

3. In addition, it does not require special browsers to view it.

As seen in the previous blog post, surface web(the place where we mostly interact like Facebook, Twitter and other social media channels), the “Deep web” and the “Dark web” are best represented by an “iceberg”. The iceberg is the perfect representation of the amount of information that is visible to us (which is hardly any!)
