Image SourceI have been learning kotlin since quite a while. Needless to say I love it :) When I started learning it I had no clue from where I should start ? Because of number of resources like videos, official documentation and books. If you haven’t started yet and planning to learn kotlin then I would like share my journey of learning kotlin.Step 1 : Get your basics clearTo start with you should go through online kotlin’s official documentation. This will teach you about language basics like syntax and other features. Cool thing I like is while reading it you can also edit and run example code snippet within your browser so that you can play around with concept that you have just read.At first looking at documentation it will be overwhelming. Don’t panic and don’t target to finish entire documentation in one go. Learn piece by piece and once you finish documentation I would recommend again go through it once.After reading documentation twice you would have rough idea about language and at least you would be able to write hello world in kotlin :)Reference - Kotlin Programming LanguageStep 2 : Kotlin KoansAfter reading documentation it’s time to play around with kotlin. Kotlin koans is programming exercises that you should try. It covers all language features and concepts. It has failing unit tests for each concept, your task is to make it pass. You can try it either online here or you can clone github repo to try in IDE(Intellij IDEA or Android studio). I would recommend cloning github repo and try it in IDE for your future reference of your own solution.Kotlin koans will push you to think about all concept you read in documentation and apply it while solving exercises. After solving it you would have nice grip on language and feel bit confident. But this doesn’t mean you are done with kotlin. At this point you know the language basics and can write code in kotlin.Step 3 : Try it in real projectNow it is time to pull up your sleeves and show some action!!!https://medium.com/media/473f4f13df2140b956f2885c54f5b684/hrefSide projects are perfect guinea pig for experimenting with new things and learning all consequences that you might face while using it in production. As a android dev I am always occupied with side project. If you are starting something fresh like new side project then it is perfect opportunity to use kotlin in your domain. Using kotlin in side project related to your area of interest will boost your confidence and eventually make you feel safe to use it in production.At this point you will come across things in kotlin that is specific to your domain (e.g Kotlin Android Extensions for android, Anko is a library providing a set of Kotlin-friendly wrappers around the Android APIs). Trying kotlin in side project not only allow you to evolve your language skills but also gives you opportunity to learn other things that might be helpful if you use it along with kotlin in your domain.If you don’t have side project to try kotlin then don’t worry. You can still try kotlin if you love to solve programming puzzles (HackerRank, TopCoder etc). I personally got inspired by Dan Lew to improve my kotlin skills by solving puzzles on advent of code (work in progress).What’s next ?Learning programming language and writing code in that language is not big deal. What matters is how you write code that is readable to others and at the same time it uses ideal approach of writing code using language features. “Idiomatic kotlin” is the term that best describes above statement and it is not something that you get it quickly. As you keep using it you would come across ideal way to implement something you wrote previously. When you come across situation like this don’t blame yourself. It is perfectly fine to write code in a way you understood language at first. Realizing best approach and refactoring your approach to best approach is the key to idiomatic kotlin. It takes time to master a programming language and kotlin isn’t exception.Finally I would like to highlight few resources I use to keep up to date with kotlin.Kotlin BlogLatest PostsKotlin - Antonio LeivaKotlin WeeklyNote : These are just few resources I use and there are many more.You can find me on twitter, G+ and LinkedIn.That’s it for now folks, happy kotling(coding) ;)Getting started with kotlin was originally published in Hacker Noon on Medium, where people are continuing the conversation by highlighting and responding to this story.
The Merkle: BitConnect Plaintiff Claims its Founders are Associated With a Large Ponzi Scheme OneCoin
Lawsuits filed in the US last week against BitConnect promoters and executives were released to the public. The identities behind the alleged ponzi scheme including director Glenn Arcaro were unraveled, and several plaintiffs have claimed that the founders of OneCoin, another large-scale ponzi scheme, were involved in BitConnect. Several lawsuits filed earlier this month suggested that Glen Arcaro practically ran the ponzi scheme as the director of US promotions, overseeing several promoters including Craig Grant and Travon James. The lawsuits accused BitConnect of running a ponzi scheme by using cryptocurrency as a cover. It promised investors a fixed income for

… and why you should really have a look at it.Since 2010, Facebook allows you to download an archive file of all your interactions with the network. It’s a 5-click easy process that your grandmother can do (more details below).Inside the .zip, lies an ‘index.html’ page that acts as a portal to your personal data. Visually, it looks like an ad-free stripped down version of Facebook that’s actually quite relaxing.As I’m trying to reduce my exposure to social networks, I decided to take a look at this info. By extrapolating the data of a single individual (me), I might be able to better apprehend the capabilities of the beast. In the end, it all comes down to what is tracked and what can be deduced from that.We all gave up on privacy…… we just don’t fully realise it.Everything you expect is there: your profile, statuses, messages, friends, pokes (Tinder’s ancestor), photos, videos, comments, events. All of it in a 500mb zip file.There’s a lot of material and you could sift it for hours. Most of the content is unsurprising but there are a few notable facts that are worth exploring.Limitless data storage periodQuite simply, Facebook never deletes anything. Unfriended friends, past relationships, former employers, previous names, address book: you name it.I created my account Friday, September 14, 2007 at 10:59am and all my actions have been recorded ever since. I feel that for the first time in history, 10 years of consistent human behavior have been meticulously gathered, stored & analysed.Exhaustive photo metadataWhenever you post a photo to Facebook, it keeps a record of all the data that’s attached to it. That seems quite obvious but I didn’t suspect it was so detailed. Have a look: Camera Maker, Model, Orientation, Exposure, F-Stop, ISO Speed, Focal Length, Latitude, Longitude & Upload IP AddressAbundant log-in & session data pointsEvery time you open Facebook, the time, location, IP address, browser & device have been recorded. If you’re part of the 1.4B people that use Facebook on a daily basis, they have enough data points to determine your everyday life patterns with great accuracy: home and work address, daily commute, wake up & bed time, travel duration & destination, etc.Flawless facial recognitionApparently, Facebook has 232 examples of what I look like.How does it know? Well, every time you tag a photo, you’re adding to an enormous, user-driven wealth of knowledge and data. Everyday, billions of people are telling an algorithm what a human face looks like, from different angles, at different ages and in different light conditions.The result? Facebook allegedly said that its image recognition models could recognise human faces with 98% accuracy & that it could identify a person in one picture out of 800 million in less than five seconds.Detailed contact listWhen you install Facebook’s app on your phone, you give it the right to see your contact list. Once that’s done, Facebook keeps ALL your contacts information forever.There’s no sneaky move here: the opt-in process on your phone is actually pretty clear about that. But seeing the phone numbers, emails & addresses of everyone you know (or knew) listed on Facebook is a bit disturbing.Get to know your advertiser… because he surely knows you.Facebook main revenue source are ads served by their powerful targeting engine using custom audiences built for advertisers.Apparently 21 advertisers got access to my Facebook information:Playstation seems to like me a lot.The thing is, Facebook’s been purposely mysterious about what type of information they share with third parties. Despite numerous requests by users throughout the world, their response is systematically:Advertisers do not give Facebook any users’ contact details. We only get such details in hashed form and they are, in any event, deleted within 48 hours. We are therefore not able to confirm what contact information an advertiser has for a particular user.But looking at Facebook Business platform provides some details about what info is used in custom audiences targeting: email, phone number, first name, last name, city, state, country, date of birth, age & gender.So Facebook has a lot of data about you & it shares it with a lot of advertisers: but what should you care?“Bring the world closer…”… to ads.I used to think there was no real drawback in ceding a lot of personal data to a 3rd party. After all, I get a free service that’s pleasant to use & really helpful.Eventually, I realised that the harm potential really depends on 2 factors: the intentions & means of action of the organisation that harvests your data.Harm potential = money * financial KPI’s — regulatory pressure.That’s were Facebook gets really frightening: it’s hugely powerful & its only objective is to maximise the time spent & interactions made with its platform (just look at its financial KPI’s).Don’t be fooled by the “bring the world closer together” motto: if Facebook’s here, it’s only to make money by selling ads. And to do that, they must target — in the most precise manner — the highest possible amount of eyeballs.The thing is, do we really care?How to get your data?Starting with Facebook in 2010 and followed by Google and Twitter in 2011 and 2012, big social networks began allowing their users to download a backup file of everything they’ve ever posted.To download your Facebook backup, just follow the 3 steps described here. Facebook will send you an email once your backup’s ready (it usually takes less than 10 minutes).For a more holistic approach, check out PersonalData.io. It’s a web service that‘s helping individuals get a hold on their personal data. They’re doing an awesome job referencing data controllers & providing request templates filled with the correct wording & legal jargon. They then publish the requests & answers online so that everyone can appreciate corporate lawyers’ talent for complexifying exchanges & dodging questions.Dig deeperMost facts presented in this article are sourced from these reports & websites.If you which to learn more or make your own opinion, I think they’re a good starting point.Facebook machine learning - Stacey Higginbotham from Fortune magazine wrote really interesting stuff on that topic.Algorithm & user profiling - Julia Angwin, Terry Parris Jr. & Surya Mattu published an awesome 4 episode series on machine bias in ProPublicaFacial recognition legal issues - The Daily Beast’s thorough report taught me a lot.Archiving your social media data - Liana Bandziulis published a great article on that topic in WIRED magazine.Thanks for making it till the end!My mom won’t be the only one reading this.I’ve learned most of what I know through the writings of others.
