Learning with Treehouse for only 30 minutes a day can teach you the skills needed to land the job that you’ve been dreaming about.
I can honestly say that besides technical knowledge, Treehouse also gave me a certain mindset, and while I generally am a very ambitious person, with each completed course I felt energized to better myself even more.
Is there any advice you’d like to share with new students who are aspiring developers?
I’ve been only for about 2+ years in this industry and I could already write tens of pages about what should and should not be done by aspiring developers, but here’s a few:
If you’re offered a project you know nothing about, take it, you’ll learn after.
Be passionate about it. If your brain doesn’t get “turned on” by new concepts, libraries, programming languages, you should not be doing it.
Get ready to learn continuously. The web is like the Universe. Ever expanding. Consequently the same has to happen to your knowledge and skill-set.
Teach others and code forward ( code forward is a concept I came up with and it comes from “pay it forward”; it basically means do a few projects for free once in a while for people who deserve it ).
Accept failure as a necessary step in self-betterment.
Research before asking questions and know when to ask. Putting in even hours or days for finding the solution will always be more rewarding in the long-run than asking a question on StackOverflow waiting to be spoon-fed the answer. That being said, asking has its place especially in a team-based environment or if the deadlines are (as they often are) very tight.
Go to as many interviews as you can. If you tell a recruiter (agent) that you’d like to go to the interview even if just for the sake of the experience, they’ll respect you for that, and will do their best to land you an interview. That being said, don’t just rely on recruitment agencies, show some initiative and contact companies on your own too. It might just be the detail that gets you hired.
Finally, keep learning, especially when you feel discouraged.

Data Science perspective: MH370
flight data are crucial
It has been a while and still no answer for
the missing airplane of flight MH370. This case may give many possibilities, so
guessing by trying each of them is painful and may lead to wrong directions,
time consuming and frustrations. So simulating both physical and mathematical
model maybe an answer
Mathematical
Model
Data Science is newly established profession
to solve problems with data insights in high volume of data, so in this case like
airplane information systems, weather condition, pattern recognition, path
selections etc.
Based in the data above, Data Scientists
like me can build specific models to adapt exact or similar scenarios of the
missing plane in the line MH370
This may give as good picture what may
happen to flight, where may landed, what weather condition we had on that time,
what other circumstances occurred and what impact they had over the plane.
Picture: Possible routes
If Malaysian Airport can provide with
specific technical information about MH370 airplane, historical data of all
MH370 flights, we may find important patterns to solve this mystery. Period
between departure and lost signal may give us the distance compared to average distance
of all MH370 flights on the same period. Adding weather condition may help us
to segments the other MH370 flights that had same weather condition to seek
specific scenarios under same weather condition. Route lines are similar to all
flights in the same airline, but segmenting them to specific conditions of the
missing flight like weather, airplane type, technical conditions, air pressure
etc… may lead us to better targets. Technical check before departure may give
us information of what have been checked or not and if there is room for
possible technical failure. If there is room for failures, we can use data from
all technical failure plan crashes to predict the time occurred the failure by
that distance also segmented to adapt most the missing flight model.
Big Data technology provides us with the
power to analyze big and complicated data sets, and there are plenty of
professionals to do so.
Physical
model- Simulation
I am not the expert of the field but it can
be very smart to build a flight simulation of MH370 based on the mathematical
model that we provided here and including other external data that have impact
on the fight itself. Sometimes visualization may bring in table other factors
that may be decisive in solving the mystery.
These represent alternative approaches to
what may help involved institutions to solve this case and I hope they may consider
these.
Team Philosophy Johan Cruyff and Charly Rexach returned to Barcelona in 1988 and began to install a philosophy that would change the way people play and view football forever. Both Cruyff and Rexach admit that it wasn't a completely new philosophy. Admitting that it was one adapted from ideas given to them by Michels, and one which many believe had been given to Europe by the Hungarian side of the early 1950s. The foundation of this philosophy was, and still is, built upon the basic template of touch, technique, maintaining possession, and stretching the pitch with continuous circulation of the ball (Tiqui-Taka).Elements that, at the time, were not valued by many Barcelona supporters (Hunter, 2012)
The chart down (OptaPro) shows the power of Barcelona over other La Liga teams, its play philosophy of short passes and ball possession.
Team Discipline and attractivness (support by fans)
With this in mind, it seems that a lot of clubs steal ideas from Barcelona that they see on the surface, such as tactics, and implement them in the short term, but fail to intertwine them into their own specifically moulded model. It is one thing to use Barcelona as inspiration, but it must be remembered that Barcelona's philosophy is tailored to THEIR own needs, no one else's, and the coaching and playing staff have grown together surrounded by it. They have lived by it and through it. Due to Barcelona's on field success, many are using various aspects of the Barcelona model to shape their own coaching methods, training programmes, and playing style etc. Often missing the point that a club philosophy needs to be self defined and fully committed to by all. There are many different styles of playing football, Barcelona have their own unique style of playing, but it should be remembered that this playing style is born out of wider and deeper beliefs in the cultural values of their personal, independent philosophy.
The in-vogue languages vary by employment sector. Financial and enterprise systems need to perform complicated functions and remain highly organized, requiring languages like Java and C#. Media- and design-related webpages and software will require dynamic, versatile and functional languages with minimal code, such as Ruby, PHP, JavaScript and Objective-C.
With some help from Lynda.com, we've compiled a list of 10 of the most sought-after programming languages to get you up to speed.
What it is:Java is a class-based, object-oriented programming language developed by Sun Microsystems in the 1990s. It's one of the most in-demand programming languages, a standard for enterprise software, web-based content, games and mobile apps, as well as the Androidoperating system. Java is designed to work across multiple software platforms, meaning a program written on Mac OS X, for example, could also run on Windows.
Beginners are advised to learn C/C++ first, as Java is not the most user-friendly of languages.
What it is: A general-purpose, imperative programming language developed in the early '70s, C is the oldest and most widely used language, providing the building blocks for other popular languages, such as C#, Java, JavaScript and Python. C is mostly used for implementing operating systems and embedded applications.
Because it provides the foundation for many other languages, it is advisable to learn C (and C++) before moving on to others.
What it is:C++ is an intermediate-level language with object-oriented programming features, originally designed to enhance the C language. C++ powers major software like Firefox, Winampand Adobe programs. It's used to develop systems software, application software, high-performance server and client applications and video games.
What it is: Pronounced "C-sharp," C# is a multi-paradigm language developed by Microsoft as part of its .NET initiative. Combining principles from C and C++, C# is a general-purpose language used to develop software for Microsoft and Windows platforms.
What it is: Objective-C is a general-purpose, object-oriented programming language used by theApple operating system. It powers Apple's OS X and iOS, as well as its APIs, and can be used to create iPhone apps, which has generated a huge demand for this once-outmoded programming language.
What it is: PHP (Hypertext Processor) is a free, server-side scripting language designed for dynamic websites and app development. It can be directly embedded into an HTML source document rather than an external file, which has made it a popular programming language for web developers. PHP powers more than 200 million websites, including Wordpress, Digg andFacebook.
What it is:Python is a high-level, server-side scripting language for websites and mobile apps. It's considered a fairly easy language for beginners due to its readability and compact syntax, meaning developers can use fewer lines of code to express a concept than they would in other languages. It powers the web apps for Instagram, Pinterest and Rdio through its associated web framework, Django, and is used by Google, Yahoo! and NASA.
What it is: A dynamic, object-oriented scripting language for developing websites and mobile apps, Ruby was designed to be simple and easy to write. It powers the Ruby on Rails (or Rails) framework, which is used on Scribd, GitHub, Groupon and Shopify. Like Python, Ruby is considered a fairly user-friendly language for beginners.
What it is: JavaScript is a client and server-side scripting language developed by Netscape that derives much of its syntax from C. It can be used across multiple web browsers and is considered essential for developing interactive or animated web functions. It is also used in game development and writing desktop applications. JavaScript interpreters are embedded in Google's Chrome extensions, Apple's Safari extensions, Adobe Acrobat and Reader, and Adobe's Creative Suite.
What it is: Structured Query Language (SQL) is a special-purpose language for managing data in relational database management systems. It is most commonly used for its "Query" function, which searches informational databases. SQL was standardized by the American National Standards Institute (ANSI) and the International Organization for Standardization (ISO) in the 1980s.
