GraphQL is a query language that is rapidly gaining wide adoption across the community.
It combines type validation with a query and filtering syntax that makes it easy to get up-and-running with a powerful web API in almost no time.
Features like running parallel queries or update-all become much easier because they are first-class citizens of GraphQL. Add to that a vibrant community that keeps creating excellent tooling and documentation, it’s clear why GraphQL has become so popular with developers
Every abstraction has a cost, and GraphQL is no exception. The added complexity and a new schema format to parse and execute mean new performance bottlenecks. In addition to performance issues, the wrong use of GraphQL can lead to architectural bottlenecks.
Instead of viewing this as a problem, NearForm took this as a challenge.

Malte Pietsch delivers this keynote on “Transfer Learning – Entering a new era in NLP” at PyData Warsaw 2019
Transfer learning has been changing the NLP landscape tremendously since the release of BERT one year ago. Transformers of all kinds have emerged, dominate most research leaderboards and have made their way into industrial applications. In this talk we will dissect the paradigm of transfer learning and its effects on pipelines, modelling and the engineers mindset.
The Science Elf explores the rise of and fall of Flash, a technology that enabled rich interactivity on the internet since the late 90s.
It became ubiquitous on the web and met its doom at the hands of the Steve Jobs, no really.
I do take issue with the statement in the video that Flash was a “flash in the pan” technology. It was prevalent for the better part of dozen years. Flash had staying power and it was only the pull of the iPhone that killed it.
Siraj Raval interviews Vinod Khosla in the latest edition of his podcast.
Vinod Khosla is an Entrepreneur, Venture Capitalist, and Philanthropist. It was an honor to have a conversation with the Silicon Valley legend that I’ve admired for many years. Vinod co-founded Sun Microsystems over 30 years ago, a company that grew to over 36,000 employees and invented so much foundational software technology like the Java programming language, NFS, and they pretty much mainstreamed the ‘idea’ of open source. After a successful exit, he’s been using his billionaire status to invest in ambitious technologists trying to improve human life. He’s got the coolest investment portfolio I’ve seen yet, and in this hour long interview we discuss everything from AI to education to startup culture. I know that my microphone volume should be higher in this one, I’ll fix that the next podcast. Enjoy!

Siraj Raval explores generative modeling technology.
This innovation is changing the face of the Internet as you read this. It’s now possible to design automated systems that can write novels, act as talking heads in videos, and compose music.
In this episode, Siraj explains how generative modeling works by demoing 3 examples that you can try yourself in your web browser.
In this era of “Internet of Code”, data and metadata around open source projects are abundantly available.
Here’s an interesting talk by Microsoft Research on AI developing software itself.
While research in program synthesis is not new, deep learning systems that take advantage of large scale code as data is starting to show new promise in improving developer productivity. The availability of GPU machines and cloud-based distributed systems help build deeper networks and scale them to production systems. In addition to passive input from open repos, crowdsourcing software expertise and integrating this with software systems has shown positive results. AI promises assistance and automation in every aspect of software development from edit and build stage to test and deploy stage. What traditional compiler and run time systems did with rules and analyzers can be replaced with AI-driven algorithmic systems. The concept of Software 2.0 is being discussed where code appears as data and where traditional software development processes give way to AI-based systems. In this panel, we explore opportunities for research and technology to improve productivity in software engineering and how AI plays a role in it.
