Creating the best Linux Development experience on Windows & WSL 2

We are really excited to have had Docker Desktop be featured in a breakout session titled “The Journey to One .NET” at MSFT Build by @Scott Hanselman  with WSL 2. Earlier in the his  keynote, we learned about the great new enhancements for GPU support for WSL 2 and we want to hear from our community about your interest in adding this functionality to Docker Desktop. If you are eager to see GPU support come to Docker Desktop, please let us know by voting up our roadmap item and feel free to raise any new requests here as well.

With this announcement, the launch of the Windows 2004 release imminently and Docker Desktop v2.3.02 reaching WSL2 GA , we thought this would be a good time to reflect on how we got to where we are today with WSL 2.

April 2019

Casting our minds back to 2019 (a very different time!), we first discussed WSL 2 with Microsoft in April. We were excited to get started and wanted to find a way to get a build as soon as possible.

May 2019

It turned out the easiest way to do this was to collect a laptop Continue reading

The Latest Modern Innovation in Architecture

Architecture is constantly changing. New materials and ideas, as well as the needs of clients, drive new innovation in architecture. The latest innovation in architecture is that there are no defining standards, allowing for a wide variety of different styles and designs.

Modern architecture places emphasis on horizontal and vertical lines, as well as 90-degree angles. Modern architecture depends a great deal on sculpture forms, smooth surfaces, circular voids, and overhead shading systems.

Innovations in architecture include such features as large horizontal windows and ample natural light, as well as outdoors entertainment areas.

Architecture Innovations for Those on a Budget

In the last few years, one of the biggest innovations in architecture is the designing of tiny houses for those on a budget. These tiny homes need to be well thought out and the innovation comes in when architects have to come up with innovative ways to fit everything that normal homes have in a small space often no larger than a small bedroom.

Some of the innovations in this include such things as built in storage solutions and multifunctional furniture to make the most of the limited living space.

Another architecture innovation is the turning shipping containers into cute Continue reading

Feedback: Data Center for Networking Engineers

When I started designing Data Center Infrastructure for Networking Engineers webinar I wanted to create something that would allow someone fluent in networking but not in adjacent fields like servers or storage to grasp the fundamentals of data center technologies, from server virtualization and containers to data center fabrics and storage protocols.

Here’s what a network architect said about the webinar:

Nvidia unleashes new generation of GPU hardware

Nvidia, whose heritage lies in making chips for gamers, has announced its first new GPU architecture in three years, and it’s clearly designed to efficiently support the various computing needs of artificial intelligence and machine learning.The architecture, called Ampere, and its first iteration, the A100 processor, supplant the performance of Nvidia’s current Volta architecture, whose V100 chip was in 94 of the top 500 supercomputers last November. The A100 has an incredible 54 billion transistors, 2.5 times as many as the V100.10 of the world's fastest supercomputers Tensor performance, so vital in AI and machine learning, has been significantly improved. FP16 floating point calculations are almost 2.5x as fast as V100 and Nvidia introduced a new math mode called TF32. Nvidia claims TF32 can provide up to 10-fold speedups compared to single-precision floating-point math on Volta GPUs.To read this article in full, please click here

Mutable References To ‘self’ In Rust’s Object Methods

Lately I’ve been working on graphics programming in Rust, as a continuation of my first steps with the language. As part of this work, I created a type I created called Vec3f, to hold cartesian coordinates for a given vector: #[derive(Copy, Clone, Debug)] struct Vec3f { x: f32, y: f32, z: f32 } In the natural course of this work, I needed to add certain methods for this type to allow me to perform calculations like cross product, and dot/scalar product.

Securing work-at-home apps

In today's post, I answer the following question:
Our customer's employees are now using our corporate application while working from home. They are concerned about security, protecting their trade secrets. What security feature can we add for these customers?
The tl;dr answer is this: don't add gimmicky features, but instead, take this opportunity to do security things you should already be doing, starting with a "vulnerability disclosure program" or "vuln program".


Gimmicks

First of all, I'd like to discourage you from adding security gimmicks to your product. You are no more likely to come up with an exciting new security feature on your own as you are a miracle cure for the covid. Your sales and marketing people may get excited about the feature, and they may get the customer excited about it too, but the excitement won't last.

Eventually, the customer's IT and cybersecurity teams will be brought in. They'll quickly identify your gimmick as snake oil, and you'll have made an enemy of them. They are already involved in securing the server side, the work-at-home desktop, the VPN, and all the other network essentials. You don't want them as your enemy, you want them as your friend.

Juniper’s big push: AI in all areas of enterprise networking

Juniper intends to spread the gospel of artificial intelligence across enterprise networking in the coming months with new products and services.The expected moves are a continuation of a strategy that has been an integral part of Juniper since the company bought wireless and artificial-intelligence software maker Mist in 2019 for $405 million.[Get regularly scheduled insights by signing up for Network World newsletters.] Mist’s cloud-based Wi-Fi Assurance system includes an AI-base engine called Marvis that features dynamic packet capture and machine learning to automatically identify, adapt to and fix network issues.To read this article in full, please click here

Helping You Better Identify Vulnerabilities in Partnership with Snyk

We are really excited that Docker and Snyk are now partnering together to engineer container security scanning deeply into Docker Desktop and Docker Hub. Image vulnerability scanning has been one of your most requested items on our public roadmap.

Modern software uses a lot of third party open source libraries, indeed this is one of the things that has really raised productivity in coding, as we can reuse work to support new features in our products and to save time in writing implementations of APIs, protocols and algorithms. But this comes with the downside of working out whether there are security vulnerabilities in the code that you are using. You have all told us that scanning is one of the most important roadmap issues for you.

Recall a famously huge data breach from the use of an unpatched version of the Apache Struts library, due to CVE 2017-5638. The CVE was issued in March 2017, and according to the official statement, while the patch should have been applied within 48 hours, it was not, and during May 2017 the websites were hacked, with the attackers having access until late July. This is everyone’s nightmare now. How can we help Continue reading

Resolve internal hostnames with Cloudflare for Teams

Resolve internal hostnames with Cloudflare for Teams

Phishing attacks begin like any other visit to a site on the Internet. A user opens a suspicious link from an email, and their DNS resolver looks up the hostname, then connects the user to the origin.

Cloudflare Gateway’s secure DNS blocks threats like this by checking every hostname query against a constantly-evolving list of known threats on the Internet. Instead of sending the user to the malicious host, Gateway stops the site from resolving. The user sees a “blocked domain” page instead of the malicious site itself.

As teams migrate to SaaS applications and zero-trust solutions, they rely more on the public Internet to do their jobs. Gateway's security works like a bouncer, keeping users safe as they navigate the Internet. However, some organizations still need to send traffic to internal destinations for testing or as a way to make the migration more seamless.

Starting today, you can use Cloudflare Gateway to direct end user traffic to a different IP than the one they originally requested. Administrators can build rules to override the address that would be returned by a resolver and send traffic to a specified alternative.

Like the security features of Cloudflare Gateway, the redirect function is Continue reading

Musings on IP Packet Reordering

During the Comparing Transparent Bridging and IP Routing part of How Networks Really Work webinar I said something along the lines of:

While packets should never be reordered in transit in transparent bridging, there’s no such guarantee in IP networks, and IP applications should tolerate out-of-order packets.

One of my regular readers who designs and builds networks supporting VoIP applications disagreed with that citing numerous real-life examples.

Of course he was right, but let’s get the facts straight first:
