“Computer programming is an art, because it applies accumulated knowledge to the world, because it requires skill and ingenuity, and especially because it produces objects of beauty.”
Donald Knuth, 1974


It’s better to start your journey into the career of programming by answering the question “Do you really need programming?” This question does not apply to those, who majored in computer programming or was close to it. If at school you were good at math, if you like to spend a lot of time sitting in front of the computer, if you want to learn something new, then programming is for you. What is more, this area is now in demand and highly paid in the world, job vacancies for the post of programmers are always open. Isn’t it the best time to be a programmer? 🙂

Everyone knows that the future programmer should be able to think broadly and to present the project from different perspectives before its implementation and realization. Unfortunately, the machine does not understand a human language. Of course, I’m not talking about Siri and other voice recognition — I’m talking about the creation of new software. To create the calculator, the computer needs to be given the task in the same way as the foreman explains to workers how to lay bricks. That’s why you can’t do anything without understanding the programming languages. Well, first you need to decide what kind of programming languages we should start with.

And here everyone chooses a language which will be useful for him. It depends on the kind of products you are going to develop. Most of us studied Turbo Pascal at school, and it’s no news that this language is practically not used anymore. So, if you want to join the team of programmers in the nearest future, the choice of language should be made sensibly.

Among the most popular programming languages in 2016 are Java, followed by C languages, then Python, JavaScript, PHP, Ruby, etc. It should come as no surprise that the more popular language is, the more chances you have to find work in the future. So, you’d better start with Java or C#, as these are the best paid and relatively simple learning languages of writing code. If you can’t cope with them, then you should try to learn Python. This language suits for quick and effective programming.

But if you have no programming experience at all you can start with something more simple for understanding. Good examples can be the basics of HTML and CSS.

Why? These two languages are essential for creating static web pages. HTML (Hypertext Markup Language) structures all the text, links, and other content you see on a website. CSS is the language that makes a web page look the way it does—color, layout, and other visuals we call style. Well, if you are interested in making websites, you should definitely start with HTML and CSS.

Let’s move to JavaScript. It is the first full programming language for many people. Why? It is the next logical step after learning HTML and CSS. JavaScript provides the behavior portion of a website. For example, when you see that a form field indicates an error, that’s probably JavaScript at work.

JavaScript has become increasingly popular, and it now lives outside web browsers as well. Learning JavaScript will put you in a good place as it becomes a more general-purpose language.

Some people also suggest choosing Python as the first programming language because Python’s program code is readable, first of all. You don’t even need to be a programmer to understand what is happening in the program. Due to the simple syntax of Python you will need less time for writing programs than in Java, for example. A huge base of libraries will save you a lot of strength, nerves and time. Large technology companies are working with Python: Yandex, Google, Facebook and YouTube. It is used for web applications, game development, software for servers.

Java can also be a good choice for a beginner. This language is more popular than Python, but a bit more complicated. At the same time, the development tools are much better designed. Java is one of the most popular languages for the backend development of modern enterprise web applications. It is used in Amazon, eBay, LinkedIn and Yahoo! With Java and the frameworks based on it, developers can create scaling web apps for a wide range of users. Java is also the primary language used for developing Android applications for smart phones and tablets. Moreover, after Java you will be able to work with low level programming languages.

PHP is one more popular language. The PHP language, along with databases (e.g. MySQL) is an important tool for creating modern web applications. Most of the sites developed on PHP are focused on a large amount of data. It is also a fundamental technology of powerful content management systems like WordPress. There are no normal imports in PHP, there are many solutions to one and the same problem. And it makes training more complicated.


The languages C and C# are a bit complicated for a beginner. But if you develop software for embedded systems, work with system kernels or just want to squeeze out every last drop from all available resources, C is what you need.

Ruby has begun to gain popularity since 2003, when the framework Rails appeared. Used widely among web startups and big companies alike, Ruby and Rails jobs are pretty easy to come by. Ruby and Rails make it easy to transform an idea into a working application, and they have been used to bring us Twitter, GitHub, and Treehouse.

Choosing a programming language may still seem challenging. It shouldn’t. You can’t go wrong. As long as you choose a language that is regularly used in technology today, you’re winning. When you are starting out, the goal is to become solid in the basics, and the basics are pretty similar across almost all modern programming languages.

Part of learning to code is learning a language’s syntax (its grammatical or structural rules). A much bigger part of learning to code, the part that takes longer and gives you more headaches, is learning to solve problems like a programmer. You can learn the grammatical structure of the English language pretty quickly; however, you won’t truly understand the language until you put that grammatical structure to use in a conversation. The same is true in programming. You want to learn the core concepts in order to solve problems. Doing this in one language is similar to doing it in another. Because the core concepts are similar from language to language, I recommend sticking with whichever language you choose until your understanding of the core concepts is solid. If you have a clear idea of your reasons for learning to program, and know exactly what you want to accomplish with your new coding skills, then you’ll be able to make the right choice.

How did you guys get into programming? What are the best programming languages for first-time learners?

The IT sector is flourishing. If you’ve used a computer for at least a couple of times in the last few years, you’ve probably noticed this. I’ve noticed it myself even more after a business trip to Stockholm where I was lucky to attend some conferences and learnt more about Swedish IT industry tendencies. These tendencies reflect our life in general. Life changes rapidly with new technologies bursting into it. And when it comes to programming languages, we get a chance to see very different trendy styles. Programming languages which were popular some years ago are not useful today. And no one can exactly predict which programming language will be popular in future. That’s why a programmer who wants to stay in developer fields has to adopt the right programming language from time to time.

As the Swedish software maker Erik Starck pointed out, “programming is about managing complexities”. And it’s really so. An understanding of at least one programming language makes an impressive addition to any CV nowadays.

It is also very difficult to get the exact number of users for any programming language. Many of us use multiple programming languages. The more experience you have, the more programming languages you use. The more programs you write or work with, the chances of using more languages rise. The larger the company, the more languages you’re likely to use.

There are a number of ways to measure the popularity of a programming language, for example, based on the number of: 1) new applications written in the language; 2) existing applications written in the language; 3) developers that use the language primarily; 4) developers that use the language ever; 5) web searches; 6) available jobs that require skills in the language; 7) developers’ favorites, etc.

My survey attempts to rank which programming languages are most popular in Sweden, each using a different measure. So, they are the following:

1) Python

Python is an object-oriented programming language which allows developers to work quickly while integrating their systems more efficiently and effectively. Designed by Guido van Rossum in 1991, Python is one of the most easy to use programming languages.

Python is characterized by its use of indentation for readability, and its encouragement for elegant code by making developers do similar things in similar ways.

Top Employers: Amazon, Dell, Google, eBay, Instagram, Yahoo

2) Java

Java is a class-based, object-oriented programming language founded by Sun Microsystems in 1995. Java is one of the most in-demand programming languages today for many reasons. First of all, it is a well-organized language with a strong library of reusable software components. Secondly, programs written in Java can run on many different computer architectures and operating systems because of the use of the JVM (Java virtual machine).

Top Employers: Amazon, Deloitte, Sun, eBay, Symantec Corporation, Cisco Systems, Samsung

3) C++

C++ is a compiled, multi-paradigm language written as an update to C in 1979 by Bjarne Stroustrup.

Due to its high-level compatibility and object-orientation, C++ is used for developing a wide-range of applications and games which makes it a popular and sought after programming language by the employers.

Top Employers: Intel, the Math Works, Microsoft, Qualcomm, Amazon, Mozilla, Adobe, Volvo

4) Ruby

Ruby is an open source, dynamic programming language designed by Yukihiro Matsumoto in 1995 with a key focus on productivity and simplicity .It is one of the most object-oriented languages in the world.

Ruby is a mix of elegant syntax which is easy to read and write and hence it has attracted many organizations and developers.

Top Employers: Spokes, VMware, Accenture, Cap Gemini, Siemens, BBC, NASA

5) JavaScript

JavaScript is an object-oriented scripting language founded in 1995 by Netscape.

Being a client-side language, it runs in the web browser on the client-side with a simplified set of commands, easier code and no need for compilation.  JavaScript is simple to learn and it is used in millions of web pages to authenticate forms, detect browsers and improve design.

Top Employers: Microsoft, Sales Force, IBM, Yahoo, Dell

6) C#

C# is a compiled, object-oriented language developed by Microsoft.

It is highly used on Windows platform and labelled as the premium language for Microsoft .NET framework. C# is known for strong typing, procedural and functional programming discipline which is the reason it has acquired so much popularity.

Top Employers: Microsoft, HP, Digi-Key Corporation, Allscripts, Intel

Those are the top 6 programming languages which are in great demand among Swedish developers.

And one more thing: remember that opinions are like noses, everyone has one and they all smell 😉 If you disagree, please feel free to email me or write your own opinions in the comments.

Working with many startups I was wondering recently why Python and Ruby are so popular and common with young and promising startups, especially Scandinavian ones as my experience shows. I am curious if anyone has analyzed the trend towards Python over Ruby with startups? Also I would like to find out what are the advantages of Python over Ruby if they are so?

I think a lot about choices and decisions at startups. Picking the language/platform to use at a startup is one of the harder decisions. Here I would like to mention the fact that most of startups today make their choice toward Python or Ruby over PHP or Java. From what I have read, PHP is just an inferior language to Python and Ruby. Even though a lot of people are using PHP because it is easy to get started, it seems to be easier to develop bad habits with PHP. Why jump on a bandwagon when you obviously know is broken? I’ve come to realize that the main reason why PHP gets into trouble with the purists is that there are just so many ways of doing one thing — it is not that standardized. I think it became the most popular language only because it’s so easy to pick up!

Python/Ruby win over Java on speed of development, and conciseness of code. This generally makes Python/Ruby a better choice for small startups for whom speed to market, and ability to implement new features matters most. Most of the modern sites chose Python when they were small startups. Only later did they have to scale. Websites tend to be horizontally scalable, meaning that for a surprising range of volumes of traffic you can just throw more webservers at it and the bottlenecks will be at other layers (for instance the database).

Searching for relevant information to compare both Pyton vs Ruby languages and analyzing customers’ demand on the software development market I found out that Python appeared to be the more popular choice for startups trying to get a minimum viable product launched and seek out potential venture capital.

This has less to do with the merits of either language and more to do with the philosophies of the frameworks represented by either language. RoR really can’t be beat as a rapid application development framework, and developers discussing Ruby on the web are generally referring to RoR. Django purports to do the same, but the overall philosophy of the python community is more minimalistic – python developers generally prefer to make their own selection of tools such as ORMs, Persistency layers and libraries.  A lot of people start Python web development with Django but move on to something more minimalistic like Flask, simply because the community seems predisposed to building its own stack in this way. RoR is more opinionated, and developers who are more predisposed to hitting the ground running, especially in the startup field, often take the Ruby fork in the road.

There is a “coming of age” point for startups coming from RoR or PHP, however.  I’ve heard about several companies who had this exact same experience and ended up moving towards something like Python or Scala.  I’m not certain this is specific to python, but I can say that as startups grow and become more ambitious, they move into problem domains poorly represented strictly by web frameworks/languages.  Search features and data extraction increasingly rely on advanced data mining techniques utilizing things like natural language processing and find they need to reengineer their stack a little to accommodate new ideas. Increasingly I see companies not abandoning their RoR/PHP/Django frontends, but creating separate REST APIs that almost always use bare python or a JVM language to take advantage of more complex computation outside of the HTTP req/response model.  Ruby could be used for this kind of offline processing, but the toolkits are just better and more mature in other languages since RoR is so prevalent in the Ruby community and consumes a great deal of the mindshare.

The fact of the matter is that most web startups represent feature sets early on where development speed is the prime concern, and so the language/framework with the biggest potential hire base and best RAD features typically win out early on.

As my personal point of view that no single language can answer every problem satisfactorily, and it is foolish to stubbornly stick to a single language for every case. Nevertheless a lot of our clients stick to Python when starting up their business. Let’s try to see what are the advantages of Python over Ruby?

The two are more similar than they are different, in everything from design to disadvantages to common uses – you can’t really go wrong either way, and shouldn’t base your decision on syntactical differences.

As Ruby developers say, Python’s main advantage has nothing to do with the language’s features. It’s more subjective: it seems that Python has more momentum amongst serious computer scientists. It’s increasingly popular in academic and scientific applications, and a lot of the technologists I respect the most seem to prefer it. By comparison, the Ruby community feels more designer-y and relatively more novice.

What this means is that while the Ruby world has very slick out-of-the-box product solutions, the Python world seems to produce more exceptionally well-written components like Tornado (web framework). Combined with it being used at Google and the potential for stuff like LiveNode to be released as open-source, I’d cast my lot with Python if I were starting today.

Thinking Python may be the best choice of startups, what is your opinion on this?

Looking forward to hearing from you!

Ruby is a dynamic programming language that gains popularity year by year due to its simple syntax and effectiveness. There are many web frameworks written in Ruby. I’m pretty sure everybody heard of Ruby on Rails, but are there any other Ruby frameworks deserving attention and offering better options than Ruby on Rails does? With the success of Ruby on Rails, is there a place left for other web frameworks written in Ruby?

Most Ruby developers are working with Ruby on Rails for building web applications. However, there are some great alternative frameworks out there that also deserve a look. Some of these frameworks borrow heavily from Ruby’s premier web framework. Many offer significant improvements in speed and flexibility. Some can be used as outright replacements for Ruby on Rails. Others are perfect for running as supplemental services, when something faster and closer to the metal is needed. And a few have entirely different goals in mind, such as providing a whole web application stack in a single file for easily deployed mini-applications. But despite all their differences each of these frameworks has at least two things in common: a great dynamically-typed human-friendly base language-Ruby-and a smart, enthusiastic core group of contributors.

Here is an overview of some Ruby web frameworks which deserve a look. Let’s see how they are similar to/different from its most popular representative-Ruby on Rails.

1. Ruby on Rails

As it was already mentioned, Ruby on Rails (sometimes known as “RoR” or just “Rails”) is perhaps the most popular Ruby framework that is in use today, and with good reason. Ruby on Rails was the framework that popularized the MVC approach. This is done primarily by the Ruby on Rails MVC framework that consists of the Model (ActiveRecord), View (ActionView) and Controller (ActionController) sub-systems. It is open source and comes with a rich set of features including: AJAX support; a host of testing, security, caching and form-validation frameworks; internalization and localization functionality; and there are also pretty standard features such as DB migration frameworks, MVC Push capability, etc. Ruby on Rails emphasizes agile development, “Convention over Configuration” – developer only needs to concentrate on the non-conventional aspects of application development, and “Don’t Repeat Yourself” – information is located in a single, unambiguous place. Since it has been around for a while, there is a well-defined API, extensive documentation as well as tutorials all over the web and finally a vibrant and supportive community. The principle difference between Ruby on Rails and other frameworks for development lies in the speed and ease of use, so developers working within the environment really enjoy it. Changes made to applications are immediately applied, avoiding the time consuming steps normally associated with web development cycle.

2. Merb

Probably the most popular alternative to Rails, Merb is a smaller, tighter framework that’s easily extensible, thread safe, faster and less opinionated. However, it maintains many similar conventions so it should be relatively familiar to existing Rails developers. With Merb you can take your pick from DataMapper, Sequel, or other Object Relational Mapping (ORM) libraries, rather than being sticked to ActiveRecord. You’re also free to choose templating engines (Erubis, HAML, Markaby, Liquid, etc) and JavaScript libraries (JQuery, Prototype, YUI, etc). One more plus is that Merb community is vibrant and growing with quick tempo.

3. Camping

At less than 4kb code size, Camping is one of the lightest Ruby frameworks around. In fact, it is one of the developers’ stated goals to always keep it below 4kb code size. It once again follows the MVC philosophy and provides a single file in which to carry out the development of the entire application , although the separation between each sub-system is still maintained. The developers also suggest that once initial or prototype development is completed in Camping, the project can easily be migrated to Ruby on Rails. So in some cases Camping is a precursory development environment for Ruby on Rails.

Camping does not have AJAX support, internalization and localization frameworks, nor security, caching and form-validation frameworks, but has pretty much other necessary functionality such as DB migration, Testing frameworks, ORM, etc.

4. Nitro

Nitro is actually a framework that was around before Ruby on Rails became popular. There are a number of web developers who still swear by it. One of its finest features is a powerful template system that has a pipeline of configurable transformation steps. It is open source and along with the template style programming, there is the option of using the MVC approach as well.

5. Ramaze

Ramaze is a very simple and straight-forward web-framework. Its emphasis is on simplicity. Ramaze also has a strict adherence to modular design and having minimal dependencies between different modules. Ramaze comes with a templating system called Ezamar and also has a fairly full-featured support for MVC applications.

6. Sinatra

Sinatra is a Ruby framework which like Camping is perhaps more suited for prototype development than actual business applications. It does, however, have a pretty standard set of features including MVC support, DB migration, Template and Caching frameworks. It does not have AJAX support, nor security and form-validation frameworks. A recent entry into the Ruby web framework space, Sinatra is designed as a minimalist RESTful framework that sits on top of Mongrel. It’s core is a simple domain specific language for defining RESTful actions and responses. Also ideal for single-file mini-applications; ORM agnostic and built on Rack.

8. Halcyon

Halcyon is another lightweight framework built on Rack for speed and light weight. It aims to provide a framework for developing service-oriented applications (SOAs) such as APIs or other non-interfaced services. It has AJAX support through the JSON interface, and overall is a very well documented project and has a strong support community.

9. Waves

Waves seeks to provide an alternative solution for applications that do not need an MVC architecture. Thus, it has support for such things as AJAX, Adobe Air, mashups, OpenID, rich-client mobile apps, etc. This is done through a rich DSL. Waves’ developer speaks of the concept of request lambdas which are basically request mapping into a certain block, which results in a certain level of flexibility by removing some of the responsibilities of the Controller and placing the emphasis more on mappings. However, note that this is a subtle or implicit modification to the MVC pattern, and so it’s better to use it only after you have a good grasp of what’s going on and are confident that this is exactly what you need.

As you can see there are a large number of frameworks for writing Ruby web applications instead of using Rails. Rails is absolutely a great framework but it’s always good to have other tools at our disposal, isn’t it?  Maybe some smaller job or certain features of any of these frameworks would be better suited to the task. Having this variety of web frameworks is healthy for the Ruby community as it not only gives developers options but also allows for exploration of innovative ideas that may not be implemented with Rails. Check one of them out if you have the opportunity – I’m sure you won’t regret this. Please note that the list of Ruby frameworks in my article wasn’t intended to be exhaustive. If I am missing some frameworks, please let me know and I will incorporate them into future posts. As always, eager to see your comments 🙂

Debates about which programming language is the best are always hard and heated. Likewise, there’s no ideal language that works for all web application project requirements. Wikipedia is written in PHP. Gmail is written in Java. Python is number one choice of Google and YouTube. Ruby is used to create Twitter and Hulu. Slashdot is written in Perl. Stackoverflow is written in C#.

Browsing for the best web programming languages, among dynamic ones, you’ll mostly see PHP, Python and Ruby listed. Back in the days several years ago PHP was admitted the best tool for web job but since then both Python and Ruby have matured and grown robust libraries and frameworks around them that make them better candidates for many web projects now.

Today many consider PHP to be great for average everyday web systems. Python and Ruby are thought to be more suitable than PHP for most web applications in general and for more advanced things in particular. Just like PHP, they are free, open source, run on an open source stack (Apache and Nginx / linux, windows and BSD), and play well with any database engine. However, Ruby and Python have better syntax and they both enforce good programming habits by their nature, especially Python. PHP encourages sloppy spaghetti code by its nature. Also, the object oriented features in PHP are very ugly because of its arcane, retarded syntax.

Let’s get deeper insights into these two web programming languages from various standpoints:

As mentioned before, Python and Ruby are two of the most popular dynamic programming languages used in high level application development. In fact, Ruby was built using some of the design elements from Python. Developers often prototype using these two languages before implementing on compiled languages because of their modularity and object oriented features. Many use Python or Ruby instead of Perl as simple scripting languages. Python and Ruby are popular among web developers as well because of their rapid development cycle, with Python boasting computation efficiencies and Ruby boasting code design.

a/ Philosophy
Python really believes that code readability is the most important thing. Hence, there is one-true way of writing code, or as it has been reformulated lately: “There’s a most understandable way to do something and that is how it should be done”. Python is designed to strongly emphasize programmer productivity and it likes things to be structured, consistent, and simple. Python syntax enforces strict indentation rules; in fact, indentation has semantic meaning in Python.
Ruby believes in giving programmer the flexibility, freedom and power. It was designed, first and foremost, to make programming fun for its creator, with guiding concepts as follow: “The Principle of Least Surprise” and “There’s more than one way to do the same thing”. The latter philosophy principle inherited from Perl is the reason why many Ruby methods have alternate names, which may lead to some API confusion among new practitioners. However, this flexibility enables Ruby to be used as a meta language for describing DSL. Also Ruby provides a better way to write concise and compact code. More into the expressiveness of the code and writing code that is clever.
Python people like libraries to be transparent and obvious how they work and hence is easier to learn, while Ruby people tend to provide clean and pretty interfaces with “magic” behind the scenes. This makes development very fast when you understand the magic, but frustrating when you don’t.

b/ Ease of Use
Python is known for its ease of use. It allows beginners to start building powerful sites more quickly, and has the power to grow in complexity keeping its ease of comprehension. For example, one of the hardest parts of coding is going back to what you coded long ago and trying to remember the logic of it. Because Python uses natural language with white spaces and indenting, it is much more clear and easier to read than languages like Ruby. That makes it easier to fix mistakes or do updates. Also, there are literally thousands of pre-built modules that can be snapped on to let you get up and running on the web immediately. Its intuitive introduction to object-oriented coding concepts, such as communities, modules, and libraries, allows you to move on to other related programming languages as they develop.

c/ Object Oriented Programming
Both Python and Ruby support object oriented programming. Still Ruby’s object orientation is considered to be more ‘pure’ in that all functions exist inside a class of some sort. Python’s object orientation is more akin to that of C++, which allows functions and statements that exist outside of classes. In Ruby, even global variables are actually embedded within the ObjectSpace object. Python doesn’t have global variables, instead using attributes of module objects. In Python and Ruby, an instance of literally any type is an object. However, where in Ruby all functions and most operators are in fact methods of an object, in Python functions are first-class objects themselves.

d/ Syntax
Ruby includes several syntactic features which make dynamic extension of and higher-order interaction with external (library) code more straightforward. In particular these are blocks and mix-ins. Most things implementable with block and mix-in syntax are also achievable in Python, they are simply less syntactically natural and clear, and so less commonly form the centerpiece of major libraries or common styles of programming. These features, combined with a lighter-weight syntax with fewer restrictions (whitespace flexibility, optional parentheses, etc), make Ruby more suitable to pervasive and relatively transparent use of metaprogramming.
At the same time, while this flexibility and the Ruby community’s tendency to use it for metaprogramming can facilitate aesthetically pleasing code, they can also create stylistic variation in how the language is used, and obscure the mechanisms by which code actually works. Python’s more restrictive syntax is intentionally designed to steer developers towards one canonical “pythonic” style to improve accessibility and comprehension.

e/ Style
Ruby code is organized into blocks, with blocks starting with various constructs and ending with the keyword “end”. Python code is indentation-sensitive, with successively larger indentation meaning tighter (nested) scopes. Python’s syntax has been described as executable pseudocode.

f/ Functional Programming
Both languages support some functional programming constructs, but Ruby is arguably better suited to a functional programming style. Lambdas in Python are generally very short, because lambdas in Python are restricted to expressions and cannot contain statements. Ruby’s lambda support is far more flexible, allowing for lambda expressions of arbitrary length.

g/ Speed
The standard CPython implementation is generally regarded as executing code slightly faster than Ruby.If speed is really an issue for a Python project, you also have the option to use Cython, Pyrex,Pypy (JIT) or the ShedSkin tools to compile your code into C or C++.

j/ Features
Both Python and Ruby are high level application development languages. Each of them is estimated to have a Capers Jones language level of at least 15. Both languages promote test driven development.
Both languages have full Unicode support, although the way that support is implemented varies. Python distinguishes between “Unicode strings” and “byte-strings”. Ruby, on the other hand, treats all strings as byte-strings with a semi-hidden flag which causes problems when dealing with badly-encoded data from third-party sources.
Both Python and Ruby support multithreading. Python has the Global Interpreter Lock (GIL), which negates much of the potential advantage of using threads; Ruby has a comparable Global VM Lock (GVL).
There are a number of functions that are available by default in Ruby but for which in Python it is necessary to import a module from the standard library. Python supports generators and generator expressions.

k/ Community
There are great communities behind both frameworks. Some people believe that Python has a more developed community in terms of libraries suited for data analysis, machine learning, natural language processing, scientific libraries. As for community folks, Python ones are believed to be conservative and afraid of change, while Ruby guys welcome changes and love new shiny stuff even if it breaks older things. Consequently, Python world is more stable, and you can update your installation without much troubles, but that also means new technology is only added very slowly.

l/ Frameworks
There are a number of Web frameworks based on both Ruby and Python. The most notable and leading are Ruby on Rails (Ruby) and Django (Python) based on MVC. Django is more declarative, with it you’ll have a clearer understanding of what’s actually going on. It lets you specify most configuration details yourself. Django creates a much simpler project structure. On the other hand, the centerpiece of Rails’s philosophy is called convention over configuration. Rails provides you with more defaults.

m/ Popularity
Python is generally more widely used than Ruby, according to most measures, but in the wake of the rising popularity of the Ruby on Rails Web application development framework Ruby’s popularity too has seen rapid growth.
Python is more mature general purpose nature vs Ruby’s more niche (Rails) usage. Python is stronger and sees use in automating system administration and software development, web application development, data manipulation, analyzing scientific data (with help of numpy, scipy, and matplotlib modules), biostatistics, and teaching introductory computer science and programming. Ruby+Rails holds a slight edge over Python+Django for web development and sees use in general programming, and has more mindshare.
In terms of cloud deployment, Python can run on Google-Cloud (Google-App engine). Though Ruby has very strong cloud deployment options in the shape of Heroku and Engine Yard.

Would you prefer Python or Ruby over PHP for implementation of your web project? And is it indeed a philosophy that you chose while selecting between Python and Ruby? Interested to hear your thoughts.
