What Makes Ruby on Rails Perfect for Marketplace Development?AlinaE-Commerce & SaaS StrategistMarketplaceRuby/RailsHomeBlogEntrepreneurshipWhat Makes Ruby on Rails Perfect for Marketplace Development?PublishedJul 13, 2020UpdatedJul 13, 202012 min readThe last several years have been marked with the rise of different marketplaces. Airbnb, AliExpress, Etsy, Booking.com are on everyone’s lips. That's not surprising that the idea of launching a second Amazon or eBay seems so appealing. To win the e-commerce race, entrepreneurs focus on providing excellent customer experience and build fast-loading and scalable websites. Besides, business owners take various security measures to protect their customers’ sensitive information. This way, they can gain clients’ trust and boost sales. When building a custom marketplace, what technology stack is best to achieve all these goals? Our answer is simple: Ruby on Rails. In this article, we will fill you in on the Ruby on Rails marketplace development. At Codica, we are passionate fans of this framework and have built numerous e-commerce platforms with its help. Based on our experience, we will discuss the key reasons to choose RoR for building a successful marketplace.

I like minimal languages and I have dwelled in the realm of Smalltalk minimalism for a long time, and as a Smalltalker I am also accustomed to a very high level of productivity, interactivity and sophistication of development environment. Nim may be productive once you get going - in fact - many people say they indeed are. But when it comes to interactivity and development environment, its very … early in the game.

Lean Canvas in JavaScript

we write code as text but think hard about all possible effects in the running system after a series of transformations. In other words, we simulate the computer in our head, while sitting in front of a computer—a powerful simulation machine.

The answer to the query above is that they both spend much of their time analyzing corpses. Pathologists analyze dead people; programmers analyze dead programs. A live program is dynamic; it changes over time; it is animated. A program is alive when it's running. When you work on a program in a text editor, it is dead. A live program has behavior, and that behavior is what we are interested in. It is very hard to discern the behavior of an organism on the basis of an autopsy. Did dinosaurs care for their young? If only we could look at some live dinosaurs and see.

Coding is a problem-solving skill, and few of theproblems that beset young people today, or are likely to in thefuture, can be solved by writing scripts or programs for computersto execute. I suggest a less ambitious enterprise with broaderapplications, and I’ll begin by listing the primary elements of thatenterprise. I think every young person who regularly uses acomputer should learn the following:

I only allowed smaller closures in the code and refactored the rest into separate top-level functions. This is a deliberate move against the common practice of js programmers. Why? Because I noticed closures make code harder to read.

The genius of the blog was not in the note-taking, it was in the publishing. The act of making your log-file public requires a rigor that keeping personal notes does not. Writing for a notional audience — particularly an audience of strangers — demands a comprehensive account that I rarely muster when I’m taking notes for myself. I am much better at kidding myself my ability to interpret my notes at a later date than I am at convincing myself that anyone else will be able to make heads or tails of them.Writing for an audience keeps me honest.

Thanks for posting this helpful, well written article. Learning programming, or any other thing one takes up, requires you to sit at one place have a plan of action for your study.

The challenges are very difficult and require great thinking ability to complete. If you are a beginner then it’s gonna be really tough for you.

Coding Scheme for Comments

“I came to Rust from Haskell, and I feel that Haskell is a very elegant and safe language. The biggest differentiator for me is that there is a greater difference between high-performance code and idiomatic ‘clean’ code in Haskell than in Rust. Most Rust code looks like most other Rust code, even when it performs well. Haskell can become unfamiliar real quick if someone is operating under different libraries and goals from what you are typically doing. Small differences in syntax can result in huge differences in behavior, and Rust has more uniformity on that axis.”

A compiler reads the program and translates it completely before the program starts running. In this case, the high-level program is called the source code, and the translated program is called the object code or the executable. Once a program is compiled, you can execute it repeatedly without further translation.

An interpreter reads a high-level program and executes it, meaning that it does what the program says. It processes the program a little at a time, alternately reading lines and performing computations.

programming is a skill that allows a computer scientist to take an algorithm and represent it in a notation (a program) that can be followed by a computer. These programs are written in programming languages.

If problem solving is a central part of computer science, then the solutions that you create through the problem solving process are also important. In computer science, we refer to these solutions as algorithms. An algorithm is a step by step list of instructions that if followed exactly will solve the problem under consideration.

The single most important skill for a computer scientist is problem solving. Problem solving means the ability to formulate problems, think creatively about solutions, and express a solution clearly and accurately. As it turns out, the process of learning to program is an excellent opportunity to practice problem solving skills.

Like mathematicians, computer scientists use formal languages to denote ideas (specifically computations). Like engineers, they design things, assembling components into systems and evaluating tradeoffs among alternatives. Like scientists, they observe the behavior of complex systems, form hypotheses, and test predictions.

In this singularity-free world, the future would be bleak for programmers. (Imagine having to cope with hundreds of years of legacy software!)

one level is chosen as the “reference”, and its mean behaviour is represented by the intercept. Each column of the resulting matrix represents the difference between the mean of one level and this reference level

As an estimate, for a scoping review of 120 studies, it could take the equivalent of 2to 3 weeks for one person one person’s time for, 2 to 3 weeks to undertake the process of coding studies,including developing and testing a coding tool, although this varies between each review

On the basis of our experience of carrying out scoping reviews, we estimate that it takes between 5 and20 minutes to apply codes to one research abstract, depending on the detail of coding required. However, priorto this process, time is needed to develop a coding tool. This involves: considering what data would inform theresearch questions, and therefore deciding the facets upon which to code, and creating a coding tool that isunambiguous, and both broad and detailed enough to describe the dataset. The tool is often developed usinga sample of data, and examining pre-existing tools.

To enhance that process, you could add the appropriate path to the output file name in this script, and write a shell script that runs this script and then commits/pushes to GitHub, and then schedule that script to run at regular intervals from your computer/server. I'm going to look into adding that functionality to this script, but it's not ready yet.

Programming is not a detail that can be left to ‘technicians’ under the false pretence that their choices will be ‘scientifically neutral’. Societies are too complex

Insisting on the glamour and fun of coding is the wrong way to acquaint kids with computer science. It insults their intelligence and plants the pernicious notion in their heads that you don’t need discipline in order to progress. As anyone with even minimal exposure to making software knows, behind a minute of typing lies an hour of study.

As many universities are being queried by the federal government on how they spend their endowment money, and enrollment decreases among all institutions nationally, traditional campuses will need to look at these partnerships as a sign of where education is likely going in the future, and what the federal government may be willing to finance with its student loan programs going ahead.

Libraries like jQuery are useful because they hide the ugly details of dealing with cross-browser differences in JS engines. But these OO-helper libraries are different: they're going to great lengths to hide the true nature of JavaScript's OO mechanisms, instead masking them in a set of patterns that are more familiar to other languages.

Procedural programming and OOP are not going to get us where we need to go by themselves.

The tech skills that people are looking for now

Two performances did seem to transcend the present, with artists sharing music that felt like open-source software to paths unknown. The first, Sam Aaron, played an early techno set to a small crowd, performing by coding live. His computer display, splayed naked on a giant screen, showcasedSonic Pi, the free software he invented. Before he let loose by revising lines of brackets, colons and commas, he typed:#This is Sonic Pi…..#I use it to teach people how to code#everything i do tonight, i can teach a 10 year old child…..His set – which sounded like Electric Café-era Kraftwerk, a little bit of Aphex Twin skitter and some Eighties electro – was constructed through typing and deleting lines of code. The shadowy DJ sets, knob-tweaking noise and fogbank ambient of many Moogfest performers was completely demystified and turned into simple numbers and letters that you could see in action. Dubbed "the live coding synth for everyone," it truly seemed less like a performance and more like an invitation to code your own adventure.

In Silicon Valley, this divide is often explicit: As Kate Losse has noted, coders get high salary, prestige, and stock options. The people who do community management—on which the success of many tech companies is based—get none of those. It’s unsurprising that coding has been folded into "making." Consider the instant gratification of seeing "hello, world" on the screen; it’s nearly the easiest possible way to "make" things, and certainly one where failure has a very low cost. Code is "making" because we've figured out how to package it up into discrete units and sell it, and because it is widely perceived to be done by men.

Without feedback, there are three options: I can believe, without evidence, that I am an awesome programmer.  I can believe, without evidence, that I am a terrible programmer and quit to go do something else.  Or finally, I can believe, without evidence, that I am a terrible programmer somehow successfully pretending to be an awesome programmer.

In programming languages like C++, C# or Java a class usually would be defined in a source code. A class definition file (Desktop.cpp/ Desktop.cs/ Desktop.java) in these languages would be a dumb text definition file fed into a compiler to verify and translate.In an interactive and lively system like Pharo a class could be created like any other object by sending instance creation methods. The reason is simple: in a pure OO environment anything is an object, so even a class is an object. Remember: there are only objects and messages.
