I got several interesting replies to my automation and orchestration blog post. Some of them were so far in the land of alternate definitions that they were literally off the charts. Here’s one of the best I got in that category:
Read more ...A few days ago I wrote an article demonstrating the Packet Tracer feature for troubleshooting Firepower Threat Defense. Another very cool tool for troubleshooting is the Capture w/Trace Feature. The power of this tool comes from both capturing a PCAP file (for Wireshark or your tool of choice) and a separate window pane that has a view of the device operation (very similar to the Packet Tracer output).
Similar to Packet Tracer, to initiate Capture w/Trace in the Firepower Management Console, choose ‘Devices‘ then ‘Device Management‘. Next, select the device that you want to perform the operation and select the icon that looks like a screwdriver and wrench.
This will produce the screen that provides health monitoring and troubleshooting for the device. Selecting “Advanced Troubleshooting” will change the view to a multi-tab troubleshooting screen.
Select the Capture w/Trace tab. The Add Capture button will allow for selection of filter criteria for the capture.
After filling out this information and choosing “Save“, an entry will be created for Continue reading

It's Docker and Kubernetes today, but what will be the magical combo for tomorrow?
Microsoft was a founding member of the Enterprise Ethereum Alliance.
The news comes after a month-long bidding war between PNI and Vector Capital.
When all of your business is driven by end users coming to use your applications over the Internet, the network is arguably the most critical part of the infrastructure. That is why search engine and ad serving giant Google, which has expanded out to media serving, hosted enterprise applications, and cloud computing, has put a tremendous amount of investment into creating its own network stack.
But running a fast, efficient, hyperscale network for internal datacenters is not sufficient for a good user experience, and that is why Google has created a software defined networking stack to do routing over the …

I have used the example of increasing paths to the point where the control plane converges more slowly, impacting convergence, hence increasing the Mean Time to Repair, to show that too much redundancy can actually reduce overall network availability. Many engineers I’ve talked to balk at this idea, because it seems hard to believe that adding another link could, in fact, impact routing protocol convergence in such a way. I ran across a paper a while back that provides a different kind of example about the trade-off around redundancy in a network, but I never got around to actually reading the entire paper and trying to figure out how it fits in.
In Gray Failure: The Achilles’ Heel of Cloud-Scale Systems, the authors argue that one of the main problems with building a cloud system is with grey failures—when a router fails only some of the time, or drops (or delays) only some small percentage of the traffic. The example given is—
The company claims it has the largest public LoRa network footprint in the U.S.
The two former rivals first partnered last year.
While it might not be an exciting problem front and center of AI conversations, the issue of efficient hyperparameter tuning for neural network training is a tough one. There are some options that aim to automate this process but for most users, this is a cumbersome area—and one that can lead to bad performance when not done properly.
The problem with coming up with automatic tools for tuning is that many machine learning workloads are dependent on the dataset and the conditions of the problem being solved. For instance, some users might prefer less accuracy over a speedup or efficiency …

Think your startup has a Big Hairy Audacious Goal? Along with President Thomas Jefferson, John Jacob Astor conceived (in 1808), and implemented (in 1810) a plan to funnel the entire tradable wealth of the westernmost sector of the North American continent north of Mexico through his own hands. Early accounts described it as “the largest commercial enterprise the world has ever known.”
Think your startup raised a lot of money? Astor put up $400,000 ($7,614,486 in today's dollars) of his own money, with more committed after the first prototype succeeded.
Think competition is new? John Jacob Astor dealt with rivals in one of three ways: he tried to buy them out; if that didn’t work, he tried to partner with them; if he failed to join them, he tried to crush them.
Think your startup requires commitment? Joining Astor required pledging five years of one’s life to a start-up venture bound for the unknownn.
Think your startup works hard? Voyageur's paddled twelve to fifteen hours per day, with short breaks while afloat for a pipe of tobacco. During that single day each voyageur would make more than thirty thousand paddle strokes. On the upper Great Continue reading
Last year at the Distributed System Summit in Berlin, Docker captains Marcos Nils and Jonathan Leibiusky started hacking on an in-browser solution to help people learn Docker. A few days later, Play-with-docker (PWD) was born.
PWD is a Docker playground which allows users to run Docker commands in a matter of seconds. It gives the experience of having a free Alpine Linux Virtual Machine in browser, where you can build and run Docker containers and even create clusters in Docker Swarm Mode. Under the hood Docker-in-Docker (DinD) is used to give the effect of multiple VMs/PCs. In addition to the playground, PWD also includes a training site composed of a large set of Docker labs and quizzes from beginner to advanced level available at training.play-with-docker.com.
In case you missed it, Marcos and Jonathan presented PWD during the last DockerCon Moby Cool Hack session. Watch the video below for a deep dive into the infrastructure and roadmaps.
Over the past few months, the Docker team has been working closely with Marcos, Jonathan and other active members of the Docker community to add new features to the project and Docker labs to the training section.
