Unikraft project promises to simplify unikernel creation

Fri, 12/08/2017 - 06:00

Unikernels promise fast boots, tiny memory footprints, and high performance, but they must be developed from scratch for each application. NEC is working to remove this barrier to unikernel adoption with a configurable unikernel code base called Unikraft.

Developed under the auspices of the Linux Foundation’s Xen Project, Unikraft will address unikernel development issues by providing libraries of operating system components that users can pick and choose from, using a menu to build a working image. Among the goals is to support multiple target platforms including Xen, KVM, and bare metal without having to do additional work to accommodate them.

Pivotal will bring serverless computing to Cloud Foundry

Tue, 12/05/2017 - 12:00

Serverless computing is coming to the Pivotal Cloud Foundry cloud computing platform, in the form of Pivotal Function Services. There’s no firm release date, but Pivotal says it’s aiming for early 2018.

With serverless computing, events happen only in response to events in an on-demand manner; Amazon Web Services’ AWS Lambda is perhaps the best-known service in this genre. Other companies also have jumped on this growing bandwagon: Google, for example, offers its Cloud Functions platform and Microsoft has Azure Functions.

Rust language gets direct WebAssembly compilation

Wed, 11/29/2017 - 12:50

Rust, the Mozilla-sponsored programming language geared to developing fast system-level software, can now compile to the WebAssembly portable code format without the need for additional tools.

Although still not officially supported, this feature was added via a pull request to enable WebAssembly as a back end by default. Through a nightly build this week, the wasm32-unknown-unknown target became natively available in Rust. (Nightly builds are unsupported test offshoots of the formal Rust language code, but their capabilities often get merged into the official build later.)

EE4J: Eclipse’s replacement for Java EE unveiled

Tue, 11/21/2017 - 20:13

The Eclipse Foundation, the new keeper of enterprise Java, has moved forward with nine project proposals for Eclipse Enterprise for Java (EE4J), which the organization describes as the first step toward the migration of Java EE (Enterprise Edition) to the open source tools organization.

The proposals, published for community review, cover aspects of Java ranging from JSON and REST to messaging. They emerge in response to Oracle’s decision in August to turn over enterprise Java to an open source tools foundation, which resulted in Eclipse taking over the project. This followed a tumultuous year for enterprise Java, with Oracle deciding on a plan to upgrade Java EE after being criticized for neglect, only to shed stewardship of Java EE this year.

Now you can port code from .Net Framework to .Net Core

Mon, 11/20/2017 - 18:09

Microsoft is looking to help developers move code from the Windows-oriented .Net Framework to cross-platform .Net Core via extended API access. But whether developers should actually make the move depends on their affinity for Windows.

Microsoft has made available a beta of Windows Compatibility Pack, adding access to APIs previously available just to .Net Framework. As a result, .Net Core developers gain access to an additional 20,000 APIs. You can get Windows Compatibility Kit via a NuGet package.

What’s next for Microsoft’s .Net CLR

Fri, 11/17/2017 - 17:49

Microsoft’s Common Language Runtime, the virtual machine that anchors the .Net Framework, is due for a makeover, with the company announcing plans to make the CLR more efficient and scalable.

Key to this modernization will be improvements to the intermediate language underlying the CLR, called IL, which has not been upgraded in ten years, said Mads Torgersen, lead designer for C# at Microsoft. The company wants to improve the IL and make the CLR a richer target for programming languages. 

[ Microsoft .Net Core 2.0: Everything you need to know. | Why .Net Core is finally ready for prime time. | .Net Framework or .Net Core? Learn when to use which. | Keep up with hot topics in programming with InfoWorld’s App Dev Report newsletter. ]

The goal of the CLR is to run .Net programs efficiently. Currently the biggest problem with .Net is the inherent limits of scalability of the runtime itself, said Ben Watson, Microsoft principal software engineer. The CLR is being pushed beyond its original intention and design. Watson explained that when multiple gigabytes of code are being loaded, algorithms built into the CLR start breaking down.

Azure IoT Edge brings smarts to devices at the cloud’s edge

Wed, 11/15/2017 - 10:00

It can be hard to pin down a definition of edge computing. Some companies look at it in terms of networks, others in terms of datacenters. For Microsoft, it’s a distributed cloud that encompasses every computer, no matter how small and how limited.

Microsoft CEO Satya Nadella uses the term “intelligent edge,” in which container-based machine learning models are deployed where needed along with your own code and Azure features like stream analytics and serverless Azure Functions.

What’s new in TensorFlow machine learning

Wed, 11/15/2017 - 06:00

TensorFlow, Google’s contribution to the world of machine learning and data science, is a general framework for quickly developing neural networks. Despite being relatively new, TensorFlow has already found wide adoption as a common platform for such work, thanks to its powerful abstractions and ease of use.

[ Go deep into machine learning at InfoWorld: 11 must-have machine learning tools. • 13 frameworks for mastering machine learningMachine learning pipelines demystified • Review: 6 machine learning cloudsWhich Spark machine learning API should you use? ] TensorFlow 1.4 API additions TensorFlow Keras API

The biggest changes in TensorFlow 1.4 involve two key additions to the core TensorFlow API. The tf.keras API allows users to employ the Keras API, a neural network library that predates TensorFlow but is quickly being displaced by it. The tf.keras API allows software using Keras to be transitioned to TensorFlow, either by using the Keras interface permanently, or as a prelude to the software being reworked to use TensorFlow natively.

Microsoft’s Mono .Net runtime brings back interpreter

Tue, 11/14/2017 - 17:59

Mono, Microsoft’s open source, cross-platform runtime for .Net-based development, has regained its .Net interpreter, about a decade after it was removed to keep Mono’s development effort manageable.

Mono’s developers are now turning their attention to using the interpreter in mixed-mode code execution, which combines interpreted code and statically compiled code.

When mixed-mode execution becomes available, developers will benefit from having core libraries optimized with the LLVM compiler platform but still have flexibility of running some dynamic code, said Miguel de Icaza, a longtime leader of the Mono project.

Scripting languages slip in popularity

Mon, 11/13/2017 - 14:58

Prominent scripting languages, once viewed as the future of programming by offering ease of use, have slipped in the monthly Tiobe index of language popularity. Only Python and JavaScript still have some momentum.

Languages that have seen their fortunes decline include Perl, PHP, and Ruby. Software quality services company Tiobe’s suspected cause is a desire among developers for higher quality than is afforded in scripting languages: “Because quality demands are getting higher and higher, hardly anybody dares to write a critical and large software system in a scripting language nowadays.”

[ What is TypeScript? Industrial-strength JavaScript. • Keep up with TypeScript’s frequent updates with InfoWorld’s TypeScript version feature tracker. | What is Python? Everything you need to know. • Tutorial: How to get started with Python. • 6 essential libraries for every Python developer. | Keep up with hot topics in programming with InfoWorld’s App Dev Report newsletter. ]

With scripting languages, most errors show up in runtime. And this is a problem, Tiobe says. Developers can write unit tests to compensate for this but it still is “quite dangerous” because these errors can happen while the application is in production. Statically typed languages, meanwhile, have responded to the threat of scripting languages by reducing type verbosity.
