New Filesharing Implementation in Docker Desktop Windows Improves Developer Inner Loop UX

A common developer workflow when using frameworks like Symfony or React is to edit the source code using a Windows IDE while running the app itself in a Docker container. The source is shared between the host and the container with a command like the following:

$ docker run -v C:\Users\me:/code -p 8080:8080 my-symfony-app

This allows the developer to edit the source code, save the changes and immediately see the results in their browser. This is where file sharing performance becomes critical.

The latest Edge release of Docker Desktop for Windows 2.1.7.0 has a completely new filesharing implementation using Filesystem in Userspace (FUSE) instead of Samba which:

  • uses caching to (for example) reduce page load time in Symfony by up to 60%;
  • supports Linux inotify events, triggering automatic recompilation / reload when the source code is changed;
  • is independent of how you authenticate to Windows: smartcard, Azure AD are all fine;
  • always works irrespective of whether your VPN is connected or disconnected;
  • reduces the amount of code running as Administrator.

Your feedback needed!

This improvement is available today in the Edge 2.1.7.0 release and will roll-out to the stable Continue reading

You Don’t Need IP Renumbering for Disaster Recovery

This is a common objection I get when trying to persuade network architects they don’t need stretched VLANs (and IP subnets) to implement data center disaster recovery:

Changing IP addresses when activating DR is hard. You’d have to weigh the manageability of stretching L2 and protecting it, with the added complexity of breaking the two sites into separate domains [and subnets]. We all have apps with hardcoded IP’s, outdated IPAM’s, Firewall rules that need updating, etc.

Let’s get one thing straight: when you’re doing disaster recovery there are no live subnets, IP addresses or anything else along those lines. The disaster has struck, and your data center infrastructure is gone.

7 ways to remember Linux commands

Some Linux commands are very easy to remember. The names may have only a couple letters and they often relate directly to what you want to do – like cd for changing directories or pwd for displaying the present working directory. Others can be very difficult to remember, especially if what you want to do relies on using a series of options.So, let’s look at some commands and tricks that can help you remember commands that do just what you need them to do and that make issuing those commands so much easier.Use aliases The best way to nail down a complicated command is to turn it into an alias. Just take a command that works for you and assign it an easy name. In fact, there is nothing wrong with using the name of the command itself as the alias as long as this doesn’t interfere with other ways you might want to use that command. For example, grep and egrep are often aliased to include using color to highlight your search term.To read this article in full, please click here

IDG Contributor Network: Secure SD-WAN: The security vendors and their SD-WAN offerings

During its inception, we had the early adopters and pure SD-WAN players. Soon it became obvious that something was missing, and that missing component was “security.” However, security vendors have highlighted the importance of security from the very beginning.Today, the market seems to be moving in the direction where the security vendors are focusing on delivering SD-WAN features around pervasive security. The Magic Quadrant for WAN Edge Infrastructure has made a substantial prediction. It states, “By 2024, 50% of new firewall purchases in distributed enterprises will utilize SD-WAN features with the growing adoption of cloud-based services, up from less than 20% today.”To read this article in full, please click here

Claudio Jeker Honored by Internet Security Research Group with Radiant Award

This week another Radiant Award has been awarded by the Internet Security Research Group, the folks behind Let’s Encrypt. The award puts the limelight on the heroes who make the Internet more secure and trustworthy each day.

The newest Radiant Award winner is Claudio Jeker, who receives the prize for his work of a BGP4 implementation on OpenBSD. This makes me horrendously enthusiastic. Why?

OpenBSD is a open-software based operating system that is focused on being secure and feature complete. It comes with a set of tools that make it ideally suited to be deployed, for instance, as a secure route server in an Internet Exchange Point (IXP). A route server is a service that an IXP can host in order to make the participating network service providers lives a little easier. They do not have to get the routing information from each other, but can simply talk to this piece of centralized infrastructure. OpenBSD allows this type of infrastructure to be build from commodity components in a scalable and secure way.

With a route server in place, an IXP can take additional measures to secure the Internet, namely by taking the MANRS actions.

Ultimately this would not be Continue reading
