The highly popular PHP 5.x branch will stop receiving security updates at the end of the year.

The highly popular PHP 5.x branch will stop receiving security updates at the end of the year. | Code it | Scoop.it

According to statistics from W3Techs, roughly 78.9 percent of all Internet sites today run on PHP.

 

But on December 31, 2018, security support for PHP 5.6.x will officially cease, marking the end of all support for any version of the ancient PHP 5.x branch.

 

This means that starting with next year, around 62 percent of all Internet sites still running a PHP 5.x version will stop receiving security updates for their server and website's underlying technology, exposing hundreds of millions of websites, if not more, to serious security risks.

 

If a hacker finds a vulnerability in PHP after the New Year, lots of sites and users would be at risk.

 

"This is a huge problem for the PHP ecosystem, While many feel that they can 'get away with' running PHP 5 in 2019, the simplest way to describe this choice is: Negligent."

 

"To be totally fair: It's likely that any major, mass-exploitable flaw in PHP 5.6 would also affect the newer versions of PHP," Arciszewski added.

 

"PHP 7.2 will get a patch from the PHP team, for free, in a timely manner; PHP 5.6 will only get one if you're paying for ongoing support from your OS vendor.

 

"If anyone finds themselves running PHP 5 after the end of the year, ask yourself: Do you feel lucky? Because I sure wouldn't."

12 Things Every Junior Developer Should Learn

12 Things Every Junior Developer Should Learn | Code it | Scoop.it
  • learn how a relational database works (this is always useful)
  • learn how HTTP works in general
  • learn how to debug code in one language (it's pretty much the same in others, you can recycle most of the knowledge)
  • be familiar with the command line
  • know how to find code (either using your IDE or grep on the command line)
  • knowing the basics of regular expressions will get you far (also to find code in the previous point)
  • know how to find solutions using a search engine
  • know how to operate git (I would say any source control but git is the de facto standard so you might as well start with that)
  • ask questions, especially if you think they're not worth being asked
  • learn how timezones work (not kidding, lots of devs are still fuzzy on these)
  • learn how unicode and utf-8 work (same reason for timezones)
  • have a general idea of how caching (CPU, in memory, disk, HTTP) works as a concept

What makes PHP 7 so special ? 5 New Features in #PHP7

What makes PHP 7 so special ? 5 New Features in #PHP7 | Code it | Scoop.it

1. SPEED!

The developers worked very hard to refactor the PHP codebase in order to reduce memory consumption and increase performance. And they certainly succeeded.

Benchmarks for PHP 7 consistently show speeds twice as fast as PHP 5.6 and many times even faster! 

2. Type Declarations

Type declarations simply means specifying which type of variable is being set instead of allowing PHP to set this automatically. PHP is considered to be a weak typed language. In essence, this means that PHP does not require you to declare data types. 

3. Error Handling

The next feature we going to cover are the changes to Error Handling. Handling fatal errors in the past has been next to impossible in PHP. A fatal error would not invoke the error handler and would simply stop your script. On a production server, this usually means showing a blank white screen, which confuses the user and causes your credibility to drop. It can also cause issues with resources that were never closed properly and are still in use or even locked.

 

In PHP 7, an exception will be thrown when a fatal and recoverable error occurs, rather than just stopping the script. Fatal errors still exist for certain conditions, such as running out of memory, and still behave as before by immediately stopping the script. An uncaught exception will also continue to be a fatal error in PHP 7. This means if an exception thrown from an error that was fatal in PHP 5 goes uncaught, it will still be a fatal error in PHP 7.

 

4. New Operators

Spaceship Operator

PHP 7 also brings us some new operators. The first one we’re going to explore is the spaceship operator. With a name like that, who doesn’t want to use it? The spaceship operator, or Combined Comparison Operator, is a nice addition to the language, complementing the greater-than and less-than operators.

Null Coalesce Operator

Another new operator, the Null Coalesce Operator, is effectively the fabled if-set-or. It will return the left operand if it is not NULL, otherwise it will return the right. The important thing is that it will not raise a notice if the left operand is a non-existent variable.

5. Easy User-land CSPRNG

What is Easy User-land CSPRNG?

User-land refers to an application space that is external to the kernel and is protected by privilege separation, API for an easy to use and reliable Cryptographically Secure PseudoRandom NumberGenerator in PHP.

Essentially secure way of generating random data.

Upgrade WordPress to PHP 7: How to Do It Safely

Upgrade WordPress to PHP 7: How to Do It Safely | Code it | Scoop.it

To upgrade WordPress to PHP 7, the process itself is easy.

 

In this article, we'll teach you how to make the switch and upgrade WordPress to PHP 7 the right way.

 

If you have full privileges on your server, you can upgrade WordPress to PHP 7 using your command line. On the other hand, if you’re on shared or managed hosting, you’ll probably have to ask your provider’s support team to upgrade your site manually.

 

In either case, the actual process is straightforward. The problem is that if you don’t take any precautionary measures, you run the risk of breaking elements of your site that don’t play nicely with PHP 7. That’s why we’re partial to a different approach that enables you to eliminate most of the risk involved.

 

Step #1: Back up your website

Step #2: Create a local staging copy of your site

There are plenty of ways to create a staging copy of your website, Try Local by Flywheel because it’s easy to set up. Plus, you don’t need to be a Flywheel customer to get the app. Just go to the website, fill out a short form, and download the tool.

Step #3: Test your staging site

Step #4: Upgrade your live site to PHP 7

There are two ways to approach it, depending on your host:

 

  1. If you use a Virtual Private Server (VPS) or any other hosting option that gives you full control, you can upgrade WordPress to PHP 7 from the command line.
  2. If your host doesn’t give you this level of access, you can ask them to upgrade you to the latest version through their support system.

 

When you’re done, be sure to test your site’s performance again (just to be safe). 

 

references:  

 

https://themeisle.com/blog/upgrade-wordpress-to-php-7/

 

https://wpengine.com/resources/upgrading-to-php-7/

 

 

 

 

nrip's insight:
You must upgrade your Wordpress sites to run on PHP7.
 
As mentioned earlier, security updates to PHP5+ branches will end on December 31, 2018.
 
Ask/Urge/Force your website developers, web managers, website hosts to move your sites to run on PHP7+

Why Javascript Developers Should Get Excited About Object.observe()

Why Javascript Developers Should Get Excited About Object.observe() | Code it | Scoop.it

Nobody is more excited about the most recent version of Google's Chrome browser than JavaScript developers.


The latest version, Chrome 36, now includes a long awaited potential update to the JavaScript language. Called Object.observe(), it’s a low-level API (see our API explainer) that might solve one of the biggest problems in modern JavaScript development.


That problem: JavaScript developers have yet to find a satisfactory way to ensure that changes in a Web app's underlying data—say, as the result of user input—are reflected properly in the browser display. (This basically reflects the fact that JavaScript developers usually separate an app's data structures and its user interface into distinct program components. That keeps the coding simpler and cleaner, but also raises issues when the two components need to communicate.)


Various JavaScript frameworks offer workarounds that developers can use to get a WYSIWYG (What You See Is What You Get) display based on exactly what their app is doing. But these workarounds add more code that can slow the app down, alter the flow of its execution and potentially introduce new bugs.


Object.observe() would simplify the problem by creating a direct pipeline between an app's data structures and its display. It can do this more easily because it's an actual change baked into the structure of the JavaScript language itself, and not just a collection of bolted-on code.


Object.observe() is still unofficial; it's so far only incorporated into Chrome, which means developers who use it can't count on it working their apps working in others browsers such as Firefox or Apple's Safari. And it's not clear when—or even whether—other browser makers will jump on the Object.observe() bandwagon.


Still, the promise of Object.observe() is such that if it clears these hurdles, it could change the way JavaScript is coded forever.

How developers can repurpose old web graphics for new mobile platforms

How developers can repurpose old web graphics for new mobile platforms | Code it | Scoop.it

Being stuck with a graphic that was created for a different purpose or platform can be discouraging. Knowing how to resize that graphic with sharper, crisper edges can make all the difference in the world.


The underlying technology behind mobile phones, tablets and even laptops and desktops is constantly changing. And changes to the screen sizes, orientations and resolutions of their screens can at times make a graphic artist go insane.


More often than not, the graphics that have been used in the past were created and sized for a specific purpose and just do not seem to look right when repurposed on a new device or platform. It is likely that many graphics were sized for the web and were right-sized and optimized for faster downloads of pages.


Unfortunately just resizing an image to a larger size does not always produce the results one expects. Sometimes you are fortunate enough to have all of the base elements used when the graphic was originally created and can ‘re-cut’ the graphic for a new purpose. Other times you may just have to start over from scratch or hire a professional designer.


There is, however, one technique that can work when all you want to do is simply repurpose a good design for a different use. If that is the case, then the following will help recycle your existing graphics used with older technologies, for new platforms that you would like to move to in the future.

Surprise! Microsoft wants its Android devices to run Windows Phone

Surprise! Microsoft wants its Android devices to run Windows Phone | Code it | Scoop.it


When Microsoft purchased Nokia it became a Android hardware manufacturer through the Nokia X line. But soon Microsoft will shift those devices to Windows Phone and the Lumia brand.



In the memos written by CEO Satyella Nadella and mobile device chief Stephen Elop announcing layoffs at Microsoft, both executives also announced a subtle change in strategy: Microsoft is planning to change the operating system of itsAndroid-powered Nokia X line to its own Windows Phone. Shocker.


According to Elop, Microsoft will continue “to sell and support existing Nokia X products” but plans to immediately shift “select future Nokia X designs and products to Windows Phone devices.” The Nokia X1, which was released earlier this year, was likely conceived and developed before Microsoft officially took over Nokia. The Nokia X2, its successor, was announced by Microsoft last month, and it will still run Nokia’s version of Android, but future low-cost devices most likely will not.

It's Time To Bet Big On Node.js

It's Time To Bet Big On Node.js | Code it | Scoop.it

Here’s a sure indication that Node.js is getting big: more employers are marking the server-side framework with JavaScript as a required job skill.


The fact that demand for Node.js jobs has grown so starkly since 2011 indicates the framework’s potential to remake the programming landscape. As need for their talent grows, Node.js developers could be some of the most highly sought after in the future.


An increasingly mobile Web has paralleled the rise of Node.js. Mobile devices make up at least 30% of total Web traffic, and Node.js is a framework with a lot to offer mobile app developers.


Mobile apps are designed to serve Web pages to mobile users. Most of the heavy lifting goes on in the back end of a mobile app, where websites are made available and managed. That means back-end frameworks, like lightweight Node.js, are enjoying a moment in the spotlight.


Node.js makes a great back-end framework for mobile development because its core purpose is to respond to network requests. The way this works on mobile is that iOS, Android and other mobile web clients connect to NodeJS over HTTP to send requests through an API.


Since Node.js is an asynchronous framework, it is able to handle multiple HTTP requests in tandem, and therefore handle more traffic than many competing back-end frameworks. Combine it with Node.js’s ease of development (since it uses popular language JavaScript), and you’ve got the technical explanation for why developers refer to Node.js as fast or “responsive.”


Larger technology companies have already noticed the appeal. In 2011, LinkedIn swapped Ruby on Rails for an overhauled mobile app running Node.js. 


The spike in job listings is an indication that still more companies are hoping to adopt Node.js into their mobile plans. Developers, it’s time to list “Node.js” higher up on your resumes.

What Makes a Good Check-in?

What Makes a Good Check-in? | Code it | Scoop.it
Few organizations have strong opinions and articulated policies on what a check-in should consist of. As long as the check-in is more or less usable in a code review, it's generally considered good enough. We can do better than this by making the contents of check-ins truly useful additions to the development process.

The central unit of work within any version-control system (VCS) is the check-in: committing one or more files into a repository. This records the current state of the files and preserves a record of their history. In this article, I examine the wide range of check-ins — from the minimal to the overly large — and identify the elements of a useful check-in and the costs of doing check-ins wrong.


 A check-in is an atomic operation that makes previously isolated changes visible to other users. A check-in can affect several files to keep the project consistent, just as a transaction can update multiple records and tables at once.  (To be accurate, some legacy VCSs such as CVS or Visual Source Safe only allow check-ins of single files. However, all modern VCSs support atomic commits across several files.)


Ideally, every check-in should move the project from one consistent buildable and tested state to the next. The VCS ensures that the history of these changes is stored durably.


A check-in differs from a database transaction in that it preserves the history of changes, including the author, and usually some documentation (a comment or link to a change request).

Similarity to Storytelling

Together, all check-ins tell the story of how a project has developed. The best stories have a strong theme, a fascinating plot, a fitting structure, unforgettable characters, a well-chosen setting, and an appealing style.


A good check-in is like a sub-plot with its own theme; it makes it easy and interesting for others to read and understand the purpose and execution of each change.

Amazon Web Services Launches New Capabilities for Mobile Developers

Amazon Web Services Launches New Capabilities for Mobile Developers | Code it | Scoop.it

Amazon Web Services  today announced several new capabilities to make it easier for developers to build, deploy, and scale mobile applications. Amazon Cognito is a new service that provides simple user identity and data synchronization that lets developers create apps that authenticate users through popular public login providers, and then keep app data such as user preferences and game state synced between devices.


The new Amazon Mobile Analytics service allows developers to easily collect and analyze app usage data, up to billions of events per day from millions of users, and delivers usage reports within an hour of data being sent by the app. AWS is also introducing a new unified Mobile Software Development Kit (SDK) that makes it easy for iOS, Android, and Fire OS developers to access the new Amazon Cognito and Amazon Mobile Analytics services as well as popular AWS services like Amazon S3 and Amazon DynamoDB.


Today, many app developers around the world use the AWS Cloud as infrastructure building blocks for the back-end services that power their mobile applications. Still, these mobile app developers have had to spend valuable time on undifferentiated heavy lifting like connecting apps to storage and database services and integrating core functionality such as authentication, user management, notifications, and usage data analytics. With Amazon Cognito, Amazon Mobile Analytics, and the AWS Mobile SDK, developers are now able to focus more of their energy on what matters, the differentiated functionality of their app that attracts and retains end users.


With AWS Mobile Services, developers can:


  • Securely store, manage, and sync user identities and data (Amazon Cognito)

  • Quickly access and understand app usage data (Amazon Mobile Analytics)

  • Easily connect apps to AWS services (AWS Mobile SDK)

  • Send notifications, updates, and promotions across platforms (Amazon SNS)

How to build your own Neural Network from scratch in Python

Most introductory texts to Neural Networks brings up brain analogies when describing them. Without delving into brain analogies, I find it easier to simply describe Neural Networks as a mathematical function that maps a given input to a desired output.

Neural Networks consist of the following components

 

  • An input layerx
  • An arbitrary amount of hidden layers
  • An output layerŷ
  • A set of weights and biases between each layer, W and b
  • A choice of activation function for each hidden layer, σ. In this tutorial, we’ll use a Sigmoid activation function.

 

The diagram above shows the architecture of a 2-layer Neural Network (note that the input layer is typically excluded when counting the number of layers in a Neural Network)

Migrating your Development Environment from PHP 5+ to PHP 7

Migrating your Development Environment from PHP 5+ to PHP 7 | Code it | Scoop.it

Many PHP applications are still running on PHP 5.x, not ready to take full advantage of the awesome features that PHP 7 offers.

 

A lot of developers have not made the switch because of certain fears of compatibility issues, migration challenges and the strange awkward feeling that migrating will take away a big chunk of their time.

 

In this tutorial, you'll learn how to upgrade your PHP 5 application to PHP 7 starting from upgrading your development environment.

 

Mac OS X

If you are a fan of Homebrew, you can install PHP 7.0 via homebrew like so:

brew tap homebrew/dupes brew tap homebrew/versions brew tap homebrew/homebrew-php brew unlink php56 brew install php70

If you were using PHP 5.6, then you should unlink the old PHP by running brew unlink php56 else unlink whatever version is present before you go ahead to install PHP 7.0.

Another option is to install it via curl on your terminal like so:

curl -s https://php-osx.liip.ch/install.sh | bash -s 7.0

Windows

If you are fan of WAMP or XAMPP, then you can just download the latest versions of the software. It comes packaged with PHP 7.0.

Download and install the last/latest version

Another option is to download the PHP 7.0 distribution for windows from http://windows.php.net/download#php-7.0.

Ubuntu

If you are running Ubuntu on your machine, especially around v14 and 15, you can install PHP 7.0 by running these commands:

sudo apt-get update sudo add-apt-repository ppa:ondrej/php sudo apt-get install -y php7.0-fpm php7.0-cli php7.0-curl php7.0-gd php7.0-intl php7.0-mysql

Note: You can check out how to install PHP 7 and Nginx here, and manually build memcached module for PHP 7.

Natural language understanding is a significant ongoing focus of Google’s AI research, with application to machine translation, syntactic and semantic parsing, and much more. Importantly, as conversational technology increasingly requires the ability to directly answer users’ questions, one of the most active areas of research we pursue is question answering (QA), a fundamental building block of human dialogue.

 

Because open sourcing code is a critical component of reproducible research, we are releasing a TensorFlow package for Active Question Answering (ActiveQA), a research project that investigates using reinforcement learning to train artificial agents for question answering

Mozilla, EFF And Others Band Together To Provide Free SSL Certificates

Mozilla, EFF And Others Band Together To Provide Free SSL Certificates | Code it | Scoop.it

Mozilla, Cisco, Akamai, the Electronic Frontier Foundation, IdenTrust and researchers at the University of Michigan are working through the Internet Security Research Group to create a new certificate authority to offer digital certificates for free to anybody who owns a web domain. The “Let’s Encrypt” group will launch this service next summer.


Currently, the EFF writes today, “HTTPS (and other uses of TLS/SSL) is dependent on a horrifyingly complex and often structurally dysfunctional bureaucracy for authentication.”


The Let’s Encrypt project aims to make getting certificates not just free, but also as easy as possible. It will take two simple shell commands to enable HTTPS for any given site that wants to use it. All of the certificates that are issues or revoked will be public and the team aims to make its protocols an open standard that other certificate authorities can adopt.


Developers who want to test the service can head over to  https://github.com/letsencrypt/lets-encrypt-preview  to take a look at the code, but this is definitely not meant for production servers yet and if you decide to ignore that warning, chances are your users will see lots of warnings about your certificate that will keep them from ever seeing your site.

We won’t go into details, but things look a little different, don’t they? We all change behaviors based on our environment. Physical location and surroundings have a lot to do with our mindset, and can influence how we do just about everything.

Behavior on a mobile phone vs. a desktop computer is no exception. Your physical location, state of mind and desired outcomes can be profoundly different depending on which device you are using, yet recent efforts to adapt desktop sites to mobile often ignore these differences and simply scale the online experience to a smaller screen. The result is a degraded end-user experience that may not meet the needs of a mobile environment, as well as disappointing outcomes for marketers and consumers.

A Brief Explanation: Responsive vs. Mobile Web

At the most basic level, it’s the difference between having one website or two. Responsive design allows the layout, scale and orientation of the desktop site to be adapted to a mobile viewing experience. The content served up to the user is the same as on a desktop site, and while they layout is organized to accommodate a smaller screen, it is important to remember that the integrity of the desktop site is intended to remain as true to form as possible and any changes to the desktop site will also affect the mobile site. Responsive design is concerned only with size and scale, not with the end user’s device type or presumed environment.


A mobile website is separate and distinct site from the desktop site, and must be maintained as such.  It is designed to cater to the mobile experience, and makes the assumption that the end user has different objectives than they would on a desktop site. This means the mobile site may not offer the full scale of content served up on the desktop version, and the options presented on the landing page may be refined accordingly.

Which is better? Well, it depends

Going back to the work party vs. weekend with friends example, it’s clear we adapt our actions according to our environment. However, the case can be made that there are some things we do no matter where we are. Here are some examples that seek to make the case that the suitability of a responsive or mobile site depends entirely on whether the people using your site are changing behavior based on their environment – or not.

Adding captions and subtitles to HTML5 video

Adding captions and subtitles to HTML5 video | Code it | Scoop.it
In other articles we looked at how to build a cross browser video player using the HTMLMediaElement and Window.fullScreen APIs, and also at how to style the player. This article will take the same player and show how to add captions and subtitles to it, using Web_Video_Text_Tracks_Format and the track element.


HTML5 and Video Captions


Before diving into how to add captions to the video player, there are a number of things that we will first mention, which you should be aware of before we start.


Captions versus subtitles


Captions and subtitles are not the same thing: they have significantly different audiences, and convey different information, and it is recommended that you read up on the differences if you are not sure what they are. They are however implemented in the same way technically, so the material in this article will apply to both.

For this article we will refer to the text tracks displayed as captions, as their content is aimed at hearing people who have difficulty understanding the language of the film, rather than deaf or hard-of-hearing people.

PredictionIO raises $2.5M and wants to be MySQL for machine learning

PredictionIO raises $2.5M and wants to be MySQL for machine learning | Code it | Scoop.it

A startup called PredictionIO has raised $2.5 million in seed capital to help it try and make a business out of open source machine learning software. Unlike previous open source projects, though, PredictionIO is designed to be easy to get started with and use, even by developers who aren’t data scientists.


PredictionIO claims developers can be writing predictive models for their applications in minutes, primarily it seems around things such as recommendation and personalization. The software is available as a download or as cloud instance on Amazon Web Services. The company itself is part of three startup accelerators – MozillaWebFWD, 500Startups and StartX.


Machine learning is a potentially lucrative software market, and PredictionIO is tackling it by trying to split the difference between open-source and proprietary tools. Open source software is popular — in machine learning that includes projects such as Mahout, scikit-learn and, at some point, Oryx — but often hard to deploy and use. Commercial software is getting much better — with the release of products likeGraphLab Create and Microsoft’s new Azure machine learning service — but can be too much like a black box, PredictionIO contends.

AWS customers can now use Nginx for media streaming

AWS customers can now use Nginx for media streaming | Code it | Scoop.it

After a year-long “pilot program,” server software maker Nginx is officially launching several paid services on Amazon Web Services (AWS) today. While Nginx Plus has been available (if not promoted) for the whole pilot program, there are two new additions to Nginx’s cloud product lineup: support for its streaming media server and annual subscriptions for all its services.


Now sites and applications using Amazon’s Elastic Compute Cloud (EC2) can use Nginx’s streaming media server as a video streaming solution. A module extension to Nginx’s web server product, Nginx streaming supports “all common video formats” — from MP4 and FLV to Apple HLS and Adobe HDS — and can adjust the quality of a video on the fly based on the speed of a connection.


Nginx Plus, Nginx’s other AWS product, is the commercial version of the popular open-source, Linux-based Nginx web server technology.


Essentially, it’s web server and networking software that you can embed inside an app. The company touts features like application load balancing, advanced cache control, and monitoring tools as reasons why AWS customers should upgrade from the free version.


“Building a great application is half the battle, delivering it is the other half … so our focus is all about application delivery,” Robertson said.


Nginx has brought annual subscription prices to its AWS customers, offering an Nginx Plus instance for $1,500 annually rather than a $0.04 per hour base price (based on EC2 instance type), and streaming media server support for $700 annually versus a $0.10 per hour flat rate.


Paying an annual subscription up front can be cheaper than paying for each service hourly, while customers who want to hedge their bets can use a combination of both annual and hourly services.

Python is Now the Most Popular Introductory Teaching Language at Top U.S. Universities

Python is Now the Most Popular Introductory Teaching Language at Top U.S. Universities | Code it | Scoop.it

At the time of writing (July 2014), Python is currently the most popular language for teaching introductory computer science courses at top-ranked U.S. departments.


Specifically, eight of the top 10 CS departments (80%), and 27 of the top 39 (69%), teach Python in introductory CS0 or CS1 courses.


Python is the most popular language in this list. It narrowly surpassed Java, which has been the dominant introductory teaching language over the past decade. Some schools have fully switched over to Python, while others take a hybrid approach, offering Python in CS0 and keeping Java in CS1. However, at the high school level, Java is still used in the AP (Advanced Placement) curriculum.


The next most popular language is MATLAB, which is often used in CS0 courses to introduce scientists and engineers to programming. C++ is next on the list, but it's been firmly supplanted by Java over the past decade. The high school AP curriculum even replaced C++ with Java in 2003. C is just as popular as C++ in this list, but some introductory courses that use C (such as Harvard's CS50) teach it alongside other languages rather than having it be the sole language.


Scheme-based languages are popular amongst a devoted subset of educators and programming language researchers. Most notably, two (somewhat rival) philosophical camps -- SICP and HtDP -- have created acclaimed textbooks and courses around the Scheme ecosystem. But in recent years, Scheme has been phased out in favor of Python at places such as MIT and UC Berkeley. It's being used in only 4 schools in this list.


Scratch is the only visual, blocks-based language that made this list. It's one of the most popular languages of this genre, which include related projects such as Alice, App Inventor, Etoys, Kodu, StarLogo, andTouchDevelop. The creators of these sorts of languages focus mostly on K-12 education, which might explain why they haven't gotten as much adoption at the university level.


Finally, note that three interesting sets of languages didn't make it on this chart because they were used in either zero or one university in our sample:

  • Statically-typed functional languages such as Haskell and OCaml, which are popular amongst PL researchers
  • Dynamically-typed languages such as JavaScript, Ruby, and PHP, which are popular amongst Web programmers
  • Widely-used industry languages that are commonly associated with specific proprietary platforms, such as Objective-C (Apple) and C#/Visual Basic (Microsoft)


If we revisit this analysis in five, ten, or twenty years, which language will be in the lead then?
