  • Open Source Survey Shows Python Love, Security Pain Points

    ActiveState published results of a survey conducted to examine challenges faced by developers who work with open source runtimes, revealing love for Python and security pain points.

  • Study Finds Lukewarm Corporate Engagement With Open Source

    Companies expect developers to use open source tools at work, but few make substantial contributions in return

    Developers say that nearly three-quarters of their employers expect them to use open source software to do their jobs, but that those same companies’ contribution to the open source world is relatively low, with only 25 percent contributing more than $1,000 (£768) a year to open source projects.

    Only a small number of employers, 18 percent, contribute to open source foundations, and only 34 percent allow developers to use company time to make open source contributions, according to a new study.

    The study follows IBM’s announcement last week that it plans to buy Linux maker Red Hat for $34 billion (£26m) in order to revitalise its growth in the cloud market, an indication of the importance of open source in the booming cloud industry.

    The report by cloud technology provider DigitalOcean, based on responses from more than 4,300 developers around the world, is the company’s fifth quarterly study on developer trends, with this edition focusing entirely on open source.

  • On learning Go and a comparison with Rust

    I spoke at the AKL Rust Meetup last month (slides) about my side project doing data mining in Rust. There were a number of engineers from Movio there who use Go, and I've been keen for a while to learn Go and compare it with Rust and Python for my data mining side projects, so that inspired me to knuckle down and learn Go.

    Go is super simple. I was able to learn the important points in a couple of evenings by reading GoByExample, and I very quickly had an implementation of the FPGrowth algorithm in Go up and running. For reference, I also have implementations of FPGrowth in Rust, Python, Java and C++.

  • anytime 0.3.2

    A new minor release of the anytime package arrived on CRAN this morning. This is the thirteenth release, and the first since July as the package has gotten feature-complete.

    anytime is a very focused package aiming to do just one thing really well: to convert anything in integer, numeric, character, factor, ordered, … format to either POSIXct or Date objects – and to do so without requiring a format string. See the anytime page, or the GitHub README.md for a few examples.

Warnings Are Your Friend – A Code Quality Primer

  • Warnings Are Your Friend – A Code Quality Primer

    If there’s one thing C is known and (in)famous for, it’s the ease of shooting yourself in the foot with it. And there’s indeed no denying that the freedom C offers comes with the price of making it our own responsibility to tame and keep the language under control. On the bright side, since the language’s flaws are so well known, we have a wide selection of tools available that help us to eliminate the most common problems and blunders that could come back to bite us further down the road. The catch is, we have to really want it ourselves, and actively listen to what the tools have to say.

    We often look at this from a security point of view and focus on exploitable vulnerabilities, which you may not see as valid threat or something you need to worry about in your project. And you are probably right with that, not every flaw in your code will lead to attackers taking over your network or burning down your house, the far more likely consequences are a lot more mundane and boring. But that doesn’t mean you shouldn’t care about them.

Canonical Extends Ubuntu 18.04 LTS Linux Support to 10 Years

BERLIN — In a keynote at the OpenStack Summit here, Mark Shuttleworth, founder and CEO of Canonical Inc and Ubuntu, detailed the progress made by his Linux distribution in the cloud and announced new extended support. The Ubuntu 18.04 LTS (Long Term Support) debuted back on April 26, providing new server and cloud capabilities. An LTS release comes with five year of support, but during his keynote Shuttleworth announced that 18.04 would have support that is available for up to 10 years. "I'm delighted to announce that Ubuntu 18.04 will be supported for a full 10 years," Shuttleworth said. "In part because of the very long time horizons in some of industries like financial services and telecommunications but also from IOT where manufacturing lines for example are being deployed that will be in production for at least a decade ."

Benchmarking Packet.com's Bare Metal Intel Xeon / AMD EPYC Cloud

With the tests earlier this week of the 16-way AMD EPYC cloud comparison the real standout of those tests across Amazon EC2, Packet, and SkySilk was Packet's bare metal cloud. For just $1.00 USD per hour it's possible to have bare metal access to an AMD EPYC 7401P 24-core / 48-thread server that offers incredible value compared to the other public cloud options for on-demand pricing. That led me to running some more benchmarks of Packet.com's other bare metal cloud options to see how the Intel Xeon and AMD EPYC options compare. Packet's on-demand server options for their "bare metal cloud" offerings range from an Intel Atom C2550 quad-core server with 8GB of RAM at just 7 cents per hour up to a dual Xeon Gold 6120 server with 28 cores at two dollars per hour with 384GB of RAM and 3.2TB of NVMe storage. There are also higher-end instances including NVIDIA GPUs but those are on a dynamic spot pricing basis. Read more

Programming: WebRender, Healthcare Design Studio GoInvo, PHP Boost and Google Cloud Platform (GCP)

  • Mozilla GFX: WebRender newsletter #30
    Hi! This is the 30th issue of WebRender’s most famous newsletter. At the top of each newsletter I try to dedicate a few paragraphs to some historical/technical details of the project. Today I’ll write about blob images. WebRender currently doesn’t support the full set of graphics primitives required to render all web pages. The focus so far has been on doing a good job of rendering the most common elements and providing a fall-back for the rest. We call this fall-back mechanism “blob images”. The general idea is that when we encounter unsupported primitives during displaylist building we create an image object and instead of backing it with pixel data or a texture handle, we assign it a serialized list of drawing commands (the blob). For WebRender, blobs are just opaque buffers of bytes and a handler object is provided by the embedder (Gecko in our case) to turn this opaque buffer into actual pixels that can be used as regular images by the rest of the rendering pipeline.

  • PHP Lands Preload Feature, Boosting Performance In Some Cases 30~50%
    PHP developers unanimously approved and already merged support for the new "preloading" concept for this web server language. PHP preloading basically allows loading PHP code that persists as long as the web server is running and that code will always be ready for each subsequent web request, which in some cases will dramatically speed-up the PHP performance on web servers. While PHP has long supported caching to avoid PHP code recompilation on each new web request, with each request PHP has still had to check to see if any of the source file(s) were modified, re-link class dependencies, and similar work. PHP preloading allows for given functions/classes to be "preloaded" that will survive as long as the web server is active. It effectively allows loading of functions or entire/partial frameworks that will then be present for each new web request just as if it were a built-in function.
  • Google Announces a Managed Cron Service: Google Cloud Scheduler
    Google announced a new Service on the Google Cloud Platform (GCP) - Cloud Scheduler, a fully managed cron job service that allows any application to invoke batch, big data and cloud infrastructure operations. The service is currently available in beta. With Google Cloud Scheduler customers can use the cron service with no need to manage the underlying infrastructure. There is also no need to manually intervene in the event of transient failure, as the services retries failed jobs. Furthermore, customers will only pay for the operations they run -- GCP takes care of all resource provisioning, replication and scaling required to operate Cloud Scheduler. Also, customers can, according to Vinod Ramachandran, product manager at Google, benefit from:
