Privacy in the Digital Age: Your Ultimate Guide

To spare you time reading, this post is for online buyers and sellers interested in a new emerging form of escrow - blockchain escrow. Because of somewhat nerdy descriptions and use of blockchain buzzwords, better if you already know what the blockchain is and how it works 😉 Still, if interested feel free to check even if you are an absolute beginner. A Brief Intro to Escrow Service Before we dive into the world of blockchain escrow, let's first review how a centralized, a.i. traditional, escrow is used. Later on, this helps us see the differences and similarities that centralized and , also known as blockchain escrow, may have. decentralized escrow So, if you have been long enough on this planet, you already know that an escrow service is often used for "something big that's worth a lot of money". Something like a Beverly Hills mansion, a supercar, a yacht, or the original Rolex Oyster that your grandpa used to wear (who knows?). In other words, you do not hand over the car keys or the family Rolex to another person. There's paperwork to be done before any purchase or sale occurs. There in the contract you and the buyer signs you outline the rules of the purchase agreement that the escrow makes sure are followed. Then, as the buyer sends the payment to the escrow bank account and it receives it, you send the keys/watch to the buyer. Once the quality is examined by the buyer, the escrow is instructed to release payment to your account. A blockchain escrow is similar in a way it also safeguards the payment while the deal is done, and then, sends it to your account. But because it is an alternative to a centralized escrow, where a single person or entity has authority over money and contract, blockchain escrow is decentralized. Let's see what that means and why a blockchain escrow might be the next big thing for a P2P market. Fun Facts to Play Around The word "decentralized" is forever linked with DeFi, and the picture most people have on their minds is staking and trading crypto on DEX. Ironically, the World Bank defines "decentralization" in the common civil context of a transfer of power to sub-national governments. In a decentralized blockchain network the data, or any change in it, is copied and distributed across all blocks of the chain. What is Blockchain Escrow Service? Let's start by giving the definition. sometimes called “decentralized escrow”, is a specific escrow system that uses a blockchain network to confirm and act on the given instructions in code instead of a human. Blockchain escrow, Because a blockchain is a network of nodes, it is fair to say that a blockchain escrow uses nodes as a substitute for bank clerks. Sounds complicated? Let's try to put it simpler. Imagine you received a wire transfer and went to the bank to get it. You've explained to a clerk what your bank visit is about. The clerk listens to you, checks the system, and then, suddenly asks you to wait a few minutes before your query is solved. Turns out the new clerk has difficulties recognizing an operation address in the system and went on to consult a senior clerk who assists, and a few minutes later you are given a receipt and moved a floor down to get your money from the cashier. Depending on where you currently live, this wire transfer withdrawal may look familiar or not. The key takeaway is that in the blockchain escrow multiple nodes must approve the transaction before it happens. That's where the "decentralized" part of it comes from. Not a single node is deemed more authoritative than the other, and all operations (later on about the types) are double-checked by the "peer nodes". But, does any blockchain can be used as an escrow? Not really. For a blockchain escrow service developers have to first , able to store both rules for how and when the deal is complete, and the money to be paid in the end. In the blockchain universe, such machines are known as . Fancy, but true. build a safe machine smart contracts Just like an army officer, a machine is given the rules and is sent to the blockchain to complete its mission. And what is the mission? To receive and release money following the rules. Sounds even more complicated now. But let's have another (and more suitable) example this time. You walk to the nearest vending machine to buy soda. There is no one near supervising your purchase, but still, you are playing by the rules. To get the soda you input the right amount of money, and voila! it falls to your lap. Now, as you are slowly piecing together what a blockchain escrow is, it's time to see how it works. How Does a Blockchain Escrow Work? At this point, you start wondering, how the blockchain and smart contracts come together as a blockchain escrow, right? In what way do they communicate and how connected they are? Well, once created and sent to the blockchain smart contracts actually live on it. So, every action that is requested by the escrow user (to receive or release the money, for example) must be approved by multiple network nodes. Such a verification process adds an additional layer of security to ensure that the contract is following its rules and no fraud is attempted. This may be the key reason why a blockchain escrow is a safer alternative to a traditional escrow service. The way a user, a smart contract, and a blockchain communicate is through code, and more specifically, smart contract calls and pre-determined functions. With that in mind, here's how it goes. A user makes a call to a contract, a.i. calls a specific function to execute. Blockchain nodes receive and confirm this operation. The function executes and brings the user expected results. Yet, the average user who may not be familiar with code may find building and integrating smart contracts with the blockchain difficult. On top of writing a smart contract code, you need a UI to make contract calls and a gateway connecting you to a specific blockchain network where requested transactions are confirmed. So, if you are a regular P2P marketplace user and not a full-blown developer, you need a blockchain escrow app or platform. It connects you to a smart contract and a blockchain network to request and confirm specific transactions without writing a line of code. The whole process for both users in this case should look like a regular escrow deal supervised by the nodes instead of humans. Below are the steps for our first blockchain product - . Zenland escrow application Either a buyer or seller fills out an escrow contract describing what, when, and how it is sold, and both approve the terms. Both must enter their cryptocurrency wallet addresses (to send and receive payment). A buyer sends the contract and the agreed payment to the selected blockchain. A seller checks if the payment is in the contract, and delivers the product/service. A buyer frees the money from the contract to a seller's wallet address. Watch a 2-minute explainer video for details, or read more in . user documentation https://youtu.be/Ge7e7C9WKTI Is Blockchain Escrow Only for Crypto and NFT? People often associate blockchain escrow with the purchase or sale of Bitcoins or other altcoins. A more recent trend is to use an escrow service for NFT. And it's easy to see why the use of smart contracts and blockchains as a secure guardian for fungible and non-fungible tokens is swelling in popularity. But can a blockchain escrow be used for real-world products or services? While it's hard to predict what the "big web3 future" holds for us, web3 escrow evolution seems inevitable. Among the clear benefits of blockchain, escrow is its proven security, transparency, and trustless nature. Given the fact that every transaction has to be confirmed before the contract executes any function requested by the user, fraudsters are having a hard time getting their hands on the money. Also, because any transaction request is recorded on the blockchain, it can easily be checked via a blockchain search tool - . blockchain explorer Last but not least, with the exception of the Ethereum blockchain, the overall than the traditional centralized escrow. Various bank fees and minor differences in banking may explain why most escrow services have a standard minimum fee or do not serve certain countries and states. fees for blockchain escrow services are lower and more flexible Yet, perhaps the biggest limitation to the widespread use of a blockchain escrow service is the difference in regional and international laws regulating third-party trade and web3. This makes it difficult to track physical goods or value items over a long distance and is likely to influence the result of the deal and users' satisfaction. On the bright side, digital trade (game items, domains, web services, etc.) is not only safer and geographically unlimited but cheaper and faster with a blockchain escrow. To eliminate the unnecessary volatility that cryptocurrency has today, Zenland users send and receive payments in stablecoins. At the end of the day, a blockchain escrow is yet to reach its full potential with more Bitcoins, NFT, domains, websites, and who knows Beverly Hills mansions being sold without escrow agents and banks. Though, in what we believe in as a team, our thousand-miles blockchain escrow journey starts with the first escrow contract on the test network. And you, an online user, can help us bring about this change.

What is Blockchain Escrow Service & How Does it Work?

When PHP developers need to prepare any enterprise-grade web application, they often prefer to use a framework. Using a framework in your coding work makes it easy for you to handle things with minimal coding. PHP frameworks also come in handy because they have coding standards that recommend good programming style, practices, and methods. But choosing a framework requires a bit of research. As a part of team (an IT Solutions Company and PIM Solution Provider) I am here to help you compare these two PHP frameworks: Laravel vs. Symfony. Syncrasy Tech Industry Stats Google Trends says that Laravel has been the most popular PHP framework for the last 5 years. Symfony is 2nd on the list. Image Source: Google Trends In this post, I’ll go through: Brief Overview of Frameworks Benefits of Laravel Benefits of Symfony Performance & Scalability Modularity Database support Popularity, Documentation & Learning Curve Image Source: Syncrasy Tech Symfony vs. Laravel: A Brief Overview When talking about Laravel, I’m referring here to all its versions 5.0, 5.1 (LTS), to 5.8 and the upcoming 6.0 (LTS) version. The framework helps you rapidly develop web applications with syntax that's simple and easy to learn, read, and maintain. Benefits of Laravel Introduced in 2011 by Taylor Otwell, Laravel has many benefits. Laravel allows separation of ‘business logic code’ from ‘presentation code’. Such separation allows you to change the appearance of a web page easily. Bug fixes with Laravel are also faster. Laravel supports integration with backend tools like and that makes web development easier and faster. Memcached Redis It fixes the most critical web application security vulnerabilities like SQL injection, cross-site scripting, and cross-site request forgery. Here is the to help web developers build more secure applications. Laravel Security Checklist Laravel which offers a convenient method for testing web applications. automates code testing with PHPUnit Symfony is an open-source web application framework. It is also popular among web developers for its reusable components as well as its libraries. Started in 2005 by French company SensioLabs, Symfony is an expandable framework. It adds unique functionality and features that can change everything within the application's framework, without having to reconfigure the entire framework. Benefits of Symfony Like Laravel, the open-source PHP framework Symfony also works on MVC architecture which is helpful for building scalable web applications. The MVC model also ensures that your project lives within a structured system that simplifies and speeds up the development process by separating business and presentation layers from each other. Symfony components are reusable and decoupled PHP libraries that work as a base for web development projects. These help you complete common tasks without writing lengthy code. components Symfony profiler is one of the best features that developers can use to track the behavior of any application by mapping all its actions and activities on the back-end side. for a full guide on how to use Symfony profiler for testing a web application. Check here Symfony has all the benefits that you expect from a PHP framework, for example speedy development, reliability of debugging with an extensible debugging toolbar, automated deployment of applications, easy documentation, and large community support. Performance & Scalability Performance and scalability are two key factors behind the success of every web application.  Laravel has a set of , while Symfony caches source code and views by default. This is the reason why Symfony has a longer website loading time. unified APIs for caching views The average loading time for websites on Laravel is about 60 milliseconds, while Symfony's load time is about 250 milliseconds. In the below image, you can see the load times of Symfony and Laravel on the two largest web servers Apache and NginX. (Image Source: Bitcoininsider.org) Laravel is based upon . At the same time, Laravel allows you to do PHP programming with less code and higher performance. If you’re thinking of building your next web application for business purposes, then Laravel works best for projects that need faster delivery with fewer resources. Symfony Components Symfony, on the other hand, requires more time, coding effort, and financial resources at the beginning stage of your projects. It also requires a lot of work for configuring its elements. But Symfony is a good choice for complex web projects, as its custom functionality works well with the requirements of your business web application. Modularity Standards Symfony is based on the that comes with a fine collection of reusable components. This ensures better modularity when developing a web application. bundled form of a modular structure Symfony Bundles (like FrameworkBundle, SecurityBundle, DebugBundle, and so on) are used to share code and features between different applications. is different. It is more restricted when you want to make quick changes to your web application. As a result, any changes to the application modules mean that developers don't just have to deal with that module, but instead with the entire unit of code. Laravel’s architecture Diagram of Laravel Architecture Image Source: Stack Overflow Symfony’s ability to organize code makes it an ideal choice for complex web development projects. This is the reason why some web developers prefer Symfony over Laravel. When it comes to the template engine, Symfony uses the which allows you to write concise and readable templates. Twig templating engine On the other hand, Laravel uses the for web applications because of its code's reusability. Also, there’s no need to define the same function twice as in the Twig template engine. Blade templating engine Both these frameworks are built on the MVC architecture. But in the end, Symfony is still the best choice for its code modularity and component reusability. Database Support The database support system is important because it allows developers to manage data and perform multiple tasks with ease. It stores, organizes, and manages information within a single software application. Using a database support system in web development projects increases efficiency in business operations and reduces costs. Both Symfony and Laravel use ORM (Object Related Mapping) for data access. Symfony ORM uses Doctrine while Laravel ORM uses Eloquent for data handling. Symfony database migrations are automatic. But developers need to define specific fields in the given code. On the other hand, Laravel uses database migrations and there is no need to define the fields. With ORM supported databases, these two PHP frameworks make it easier to process data and data manipulation. Symfony provides a few more options for database support, for example: MySQL Oracle Drizzle SQLServer PostgreSQL SQLite SAP Sybase SQL Anywhere While Laravel supports only a few of them: MySQL PostgreSQL SQLite SQLServer As you can see with these options, Symfony supports more databases than Laravel. Because of this, data manipulation and data management become much simpler with Symfony. So Symfony wins this one. But Laravel's functionality allows you to avoid bulky and large code blocks. Laravel also saves you time and effort on web projects rather than doing tedious, repetitive tasks. It supports many important tools that help make common tasks easier. It also automates functions like authentication, queuing, sessions, caching and routing. Popularity, Documentation & Learning Curve Choosing the right framework is always important for a developer whether you're updating your web application's content or website content. Choosing a PHP framework based on its popularity can bring some benefits. With a more popular framework, you get a large amount of training and support information online. You can find useful tutorials online for Laravel in the , , , , and . Laravel documentation Laracasts discussion forum Treehouse Sitepoint Codebright The Laravel are also extensive and provide excellent information that Symfony doesn’t provide. Github docs is also available but has more topics on bundles, components, service containers, and other sets of features. has more than 600,000 developers and contributors from more than 120 countries that help fix bugs and identify coding errors. Symfony documentation Symfony’s community Symfony is also popular among web developers. It shares great documentation, even though the resources are not as extensive as those for Laravel. In the end, Laravel is more popular than Symfony. There are more than on the web built using the Laravel framework. To compare, the number of websites built on Symfony is around 33,000. You can check for more information. 1 million websites here In the End From the points mentioned above, it’s clear that both Laravel and Symfony are rich in features. Both are suitable to use on a wide range of web development projects. Laravel is often preferred by developers for its rapid development, performance, and speed. Symfony is suitable for the development of complex and large-size web applications. You must use whatever suits your web project. Just make sure you choose the framework that you feel more comfortable with for the development of your web apps.

PHP Laravel VS Symfony: A Detailed Comparison of Web Development Frameworks

Whiteboard coding interviews can cost you a job wow this article did have quite a few claps, getting closer to 17k! I’m grateful to everyone who showed support! Just to give you an update, I’m now a software engineer at ASOS and could not be happier than this. Well actually I’ll be even happier in a few days, when my first kid will be born 😍I have many ideas for new articles, I will just need to find the time to write them. Want to get notified? is the best way! march 2019: Adding me on Twitter Recently I’ve been quite close to getting a job at one of the . I went through the screening process and the smoothly but I failed to pass one of the final stages, a set of one to one, or two to one, interviews: Big 5 take-home assignment : algorithms. Whiteboard coding interview Technical interview: , CS, React. JavaScript Culture fit: that. : this maybe in another article :P Second whiteboard interview It went wrong There are a few mistakes that contributed to this temporary debacle. I may have passed the technical test and the culture fit (let’s just assume that) but I admittedly performed badly at the whiteboard coding interviews. Thinking in retrospective about that day I couldn’t expect any different outcome.The truth is: . I’m not prepared to do whiteboard interviews Whiteboard interviews ( ) The whiteboard interview is, in some ways, a hybrid of a technical test of the depth of your knowledge and also a social exercise source We all know what it is, right? it’s not much about the code, it’s about your solving abilities, it doesn’t matter if etc etc… I’m a frontend developer, I generally don’t implement interview-like algorithms on the fly or articulate my thought process while I code, I sort of make interactive UIs most the time with algorithms. When I need to implement one that I didn’t use for a while, I just start researching. How much do these tests tell about a candidate anyway? even said: Someone In real life, you would rarely just whip up an off-the-cuff algorithm from memory in the middle of a coding session. You are almost always going to use an existing library, which has its own test suite, and has survived the scrutiny of other developers. The only world where you would actually need to be able to recall an algorithm would be a post-apocalyptic one, where the hard drives of all the computers connected to the internet were fried, and all copies of foundational academic papers and computer science textbooks had been reduced to ashes. My opinion tend to match the one of the aforementioned author although I like to believe that such a skill (being good at whiteboard interviews) is about having a set of very good to have other skills, soft and hard. Mitigating circumstances first I’ll make this list because you may relate to some of them but most of all I still have to vent a little bit 😄 I didn’t do the interview in my first language. Under the spotlight, it gets harder. I’m a self taught frontend developer. I lack an academic preparation. I didn’t do many interviews in my career. And not many of them had whiteboard interviews kind of tests. I don’t do much public speaking. Unfortunately, at the moment, not much. You could object that none of these are actually mitigating circumstances and you would be right. By definition, mitigating circumstances are out of our control: the truth is that I could , , , . improve my English do more CS do more interviews do more public speaking I’m gonna try to solve that first whiteboard test the way I should have done that day and I’m going to try to report the process here. The Test ['Tokyo', 'London', 'Rome', 'Donlon', 'Kyoto', 'Paris']

// YOUR ALGORITHM

[    [ 'Tokyo', 'Kyoto' ],    [ 'London', 'Donlon' ],    [ 'Rome' ],    [ 'Paris' ]] That’s it. If you rotate the letters of each city you may or may not match another city. In case you do, put them together in a array on their own. At work you’re escaping labyrinths of thousands of lines of code on a daily basis, how difficult is to show these people how to solve this simple and even kinda funny problem? Hold my beer. Yeah… Let’s pretend it went slightly differently. The perfect whiteboard interview Catchy paragraph title, although wrong. This is just the way I could have solved this test, both code and thought articulation. Who know how many other ways there are! thank you very much. I’ll gladly solve this problem for you (little bow) Me: First question, do the letters just ‘rotate’ or they can be randomly mixed up? Me: (to protect the privacy of the interviewers, I changed their name into a fancy one): Just rotate. First letter goes last, etc. Larry One at a time. IMPORTANT NOTE There are a few comments of people proposing their solution to this problem. First of all thank you, one day I’m gonna look at them all and do something with them :) But it’s not the point of the article to get the most performant solution out of this. Also please pay attention to my last question to the interviewer. Many skip this part when they comment with their solution: letters rotate If you do so, combinations like and would match: they shouldn’t. Tokyo matches only with: okyoT, kyoTo, yoTok, oToky. See? 5 letters, 5 possible combinations. There’s an hint for you there. Let’s continue. one by one. It’s not enough to .split and .sort the letters. tokyo yookt right. Me: right. Larry: Right! I guess to start I would need a way to rotate the letters of each city. Tokyo would became okyoT, then kyoTo, oh cool! we’ve got kyoto now! Ok, I’m going to need a function to do that. Me: I also need a way to loop through the input cities, ‘rotate’ the letters, do some matching and lastly grouping them together. I see that the input and the output are both arrays and they both contains the same values, the only difference is the depth of the two arrays, a flat one and an array of arrays. Me: I’m gonna write some pseudocode now to validate my thoughts. Later I’m going to test it too, cause I’m that good. 😏 Still me: function groupCitiesByRotatedNames(cities) {

  // use a variable to contain the output.  let output = [];

  // loop through each of the cities  //  rotate the name in any possible combination  //  check if the output contains a city that matches a combination  //   add that city to the array containing the match  //   otherwise add the city to the output as a new array

  return output;} Me, confident as a rockstar: let’s pseudotest my pseudocode (😛). const input = ["Tokyo", "London", "Rome", "Donlon", "Kyoto", "Paris"];

console.log(groupCitiesByRotatedNames(input));

// That's how it would build up. The final output would be the last array:

// [//     ["Tokyo"]// ]

// [//     ['Tokyo'],//     ['London']// ]

// [//     ['Tokyo'],//     ['London'],//     ['Rome']// ]

// [//     ['Tokyo'],//     ['London', 'Donlon'],//     ['Rome']// ]

// [//     ['Tokyo','Kyoto'],//     ['London', 'Donlon'],//     ['Rome']// ]

// [//     ['Tokyo','Kyoto'],//     ['London', 'Donlon'],//     ['Rome'],//     ['Paris']// ] Let’s start implementing this algorithm. First, the utility to rotate the letters of the city names. I will create a utility function: Me: let’s make this function a bit smoother (and less readable). Overconfidence at its peak. Right! I like the reduce method, I’m gonna use it again! (It’s also very functional-programmy so it’s cool to use in an interview 😎) Me: The method applies a function against an accumulator and each element in the array (from left to right) to reduce it to a single value ( ). **reduce()** MDN Our single value being the desired output. Let’s sum up what this algorithm does: We check for each city in the cities array, we rotate the name and we match every combination with the accumulator value. If we find something we add the new city to the array containing the matches (with ) otherwise we just a new array containing our new city. Array.splice push Et voila’: All together now! . Get the Gist here but this is what came to my mind that day.(It’s complexity is quadratic while you may want to solve it with an algorithm that takes linear time O(n)). This solution is not the best one My actual whiteboard interview I started from the solution. I said, ok, I’m gonna need a reduce method. I immediately approached the board to write actual code without really knowing the plan. I did have an idea of the solution, pretty much the one I wrote in the previous chapter, but I didn’t it, I didn’t really it consistently to my poor interviewers. So I got lost in the code, I lost the the train of my thoughts several times, I also stumbled on syntax errors, in a mix of poor written pseudocode and actual code. There was no way to turn the tide at this point. A performance like this can make a lot of damage to the outcome of the interviews, especially if you let this affect the rest of the process on your side. articulate explain What should I do now Practice, practice, practice. Get a whiteboard, pick a problem and talk out-loud to the air and write, do that a lot. Practice the whiteboard interview, learn the routine. Your routine, any routine. Learn it like a song on the guitar, a card trick or whatever dangerous stunt with your skate. You need to prepare a speech, it’s like a presentation. It’s like a presentation with variables. A variable is the problem. I’ll go like this: I’ll spend some time analysing the requirements (1 min) I’ll formulate questions if necessary and get answers (3 min). I’ll pause and think of a direction to take (few min, don’t be afraid to stay silent for a while). I will propose initial solutions and get feedback from the interviewers (5 min). I will pause again and choose a solution (2 min). I will write pseudocode (5 min) I will test my pseudocode (5 min) I’ll finish by transforming the pseudocode into actual code. (until necessary) In around 30 min I will have solved the problem in a enjoyable and ordinated way.

If you are a web designer probably you are not going to deal with complex algortihms, but if you are front-end developer maybe a little more and if you are a back-end developer much more. fundamental Here i will present you a list of 5 points, , with resources to improve our programming logic. that in my opinion This article is for if we manage to develop a good logic we will be ​​in a flexible way, everyone, able to move through the different languages try to do not depend on the language. 1.- Think to solve Programming is about solving problems, a good tecnique is to split the big problem in small ones to focus on each problem in a better way, you can use pseudocodes in a program or in a simple paper. 2.- Practice The most important point is this: An algorithm is nothing more than an ordered and finite set of operations that we carry out for the sole purpose of finding a solution to a problem. So try to practice simple problems to get a better logic. practice. 3.- Learn about Data Structures and Algorithms Learning about structures will give you a better plan to focus your problems and have an efficient software. You can play games like nd practice . Chess a Mathematics 4.- Learn programming paradigms A very good point is to learn programming paradigms. Probably one of the most programming paradigm is the (OOP). A programming paradigm is like a blueprint to follow to create our projects. You can learn Functional Programming to learn how you can develop programs and solve problems in a different way. The Object-Oriented Paradigm 5.- Look at other people’s code In programming we have many ways to solve problems, maybe another person solved the problem that you have in an optimal and simple way. Looking at other people’s minds is essential to advance as a programmer. You have to see a lot of great projects.

5 points to improve your programming logic

, like some many others, gift us a great phrase respect vocation and passion: _“Find a job you like and you add five days to every week”. I_n my opinion the fact to be developer is a job that we have to do it with vocation, i mean, The tech world grow every day, Jackson Brown the inclination or interest that a person feel inside to dedicate a determind way of life or job. so if you hate learning, you are out… If we have for what we do, why not try to be a better professional every day? passion Right now, i will show you a list of topics that will transform you in a better professional. Is important to say, that learning all this stuff and is not a fast travel, so we are going to need a lot of and is not easy, effort perseverance. The last thing I will tell you is that it to be an expert in all these subjects, if you are, good for you, but as a developer if you are interested in learning more you will be better. The more knowledge you acquire is not necessary your preparation will be better. Mathematics: Mathematics is going to give you a logic necessary to program in a better way. Learn about arithmetic, algebra, discrete mathematics, geometry and statistics. Algorithms and Data Structures: For me, this is one of the three/four subjects that are . The more knowledge you have of algorithms and data structures (do not depend on the language) the more efficient you will be when it comes to solving day-to-day problems. Learn about piles, trees, Linked List, Queue, ordering methods, graphs, etc. fundamental Databases: This is the other subject that, in my opinion is fundamental. Like as developer is probably that you are going to be in contact with a database manager. Study and learn about SQL and NoSQL databases and when to use each one. This theme will make you grow as a professional in an extraordinary way. Computer architecture: Know how to a computer works is are going to give you a top picture of how and why things work. Learn how the microprocessor works, hierarchy of memories, hard drives, etc. Operating systems: You must know how your operating system works. Basically the O.S is the most important software, learn how it works to have a better approach when developing. Learn about commands, memory management, etc. Networks: Nowadays everything is connected, therefore knowing about computer networks is fundamental. Learn about protocols such as TCP / IP, FTP, HTTP, how the Internet works, servers etc. Paradigms and Design Patterns: This will give you a better way to develop computer programs, in each language there are different (sometimes not) paradigms and design patterns. Learn about object-oriented programming, functional programming, reactive, SOLID principles, etc. English: If you are not a native english speaker, like me (this is a good oportuniy to say sorry if i make any english mistake), know about english is fundamental, especially technical english, because most of the books, documentation, blogs, articles are written in english. Learn to speak, write, read and listen english. Teamwork: Today is mandatory to know about version control to work as a team. Learn about Git, Github, SCRUM etc. If you are in a team, humility is fundamental, you can not put yourself above your teammates, because it is a TEAM. And a team needs everyone helping and learning every day. ◾️ Ux Design. ◾️ Computer security ◾️ Robotics ◾️ Leave another one.

Abilities that makes you a better developer

By , former VP Engineering at Addepar. on . Vladimir Novakovski Originally published Quora I have so far interviewed over a thousand engineers, data scientists, and quants and hired over a hundred within the hedge fund space, Quora, Addepar, and other companies. One thing to keep in mind is that you can’t to be a strong engineer or computer scientist. That comes from experience, education, and natural talent and shouldn’t be done in the context of the pressure of the job market. There’s nothing worse than interviewing someone who just memorized some things a few days earlier and doesn’t really understand them. prepare What you prepare for is the setting of an interview, where you have to think on your feet and generate discussion, answers, and code quickly. Equally important is to talk to industry experts and understand where your skill sets and interests are a good match, in terms of companies and groups. can For the mechanics of the technical interview before you start talking to companies, I’d suggest . They have an excellent set of technical problems that map out to actual questions asked in interviews and a robust platform to solve these problems and get realtime feedback with a low time commitment from your end. Codefights Once you’re ready, you need to understand what particular companies are looking for and how your strengths apply. If you are interested in practice interviews and feedback on how you index on these dimensions, I recommend checking out , a new recruiting platform that connects candidates with established industry veterans for technical interviews and referrals. Full disclosure: I am an advisor to the company. HiDimensional The main benefit in the platform, beyond the personalized feedback interviewers like myself share, is that we write recommendations of candidates who do well and refer those candidates to startups hiring on the platform that match their skill set. It’s an effective way of understanding your strengths and interests and fast-tracking the hiring process with a credible endorsement. By , former VP Engineering at Addepar. on .
