When I say “rock star”, you probably have all kinds of images that pop up in your head. Private planes, penthouse suites, grand stages, and wheelbarrows full of money are probably on that list somewhere. Maybe you’re a purist and you think of someone dedicated to the craft of entertaining the masses and trying to claw their way to fame one note at a time. But I’m also sure in both of those cases you also think about the negative aspects of being a rock star. Like ego. And lack of humility. I want to touch on some of that as it pertains to our jobs and our involvement in the community.
The rock star mentality at work is easy to come by. Perhaps you’re very good at what you do. You may even be the best at your company or even at the collection of companies that are your competitors. You’re the best senior architect there is. You know the products and the protocols and you can implement a complex project with your eyes closed. That’s how people start looking at you. Larger than life. The best. One of a kind.
And that Continue reading
Today's Heavy Networking digs into VyOS, an open-source, Linux-based network OS for routing. Forked from the Vyatta Core, VyOS includes a full routing stack and features including firewalling, VPN, and more. Guest Yuriy Andamasov, the project coordinator, gives us a guided tour.

The performance of applications on the web platform is becoming increasingly bottlenecked by the startup (load) time. Large amounts of JavaScript code are required to create rich web experiences that we’ve become used to. When we look at the total size of JavaScript requested on mobile devices from HTTPArchive, we see that an average page loads 350KB of JavaScript, while 10% of pages go over the 1MB threshold. The rise of more complex applications can push these numbers even higher.
While caching helps, popular websites regularly release new code, which makes cold start (first load) times particularly important. With browsers moving to separate caches for different domains to prevent cross-site leaks, the importance of cold starts is growing even for popular subresources served from CDNs, as they can no longer be safely shared.
Usually, when talking about the cold start performance, the primary factor considered is a raw download speed. However, on modern interactive pages one of the other big contributors to cold starts is JavaScript parsing time. This might seem surprising at first, but makes sense - before starting to execute the code, the engine has to first parse the fetched JavaScript, make sure Continue reading
Every time a new simple programming language is invented, we go through the same predictable cycle:
A few years ago we experienced the same cycle when OpenFlow was the-one-tool-to-bind-them all.

From time to time I run into situations where someone would like to install the Cumulus Linux operating system as well as additional packages that aren’t part of the default binary install package. This short excerpt is meant to assist in helping get those additional packages into an air-gapped environment for the install where you don’t have a repo or mirror available to pull from.
For instance, let’s say we want to install TACACS+ on an air-gapped switch and we don’t have access to a mirrored repo. There is a very tedious method which I’ll outline first, then there is the more Linux admin like option which is much more streamlined.
One thing that could be done is to run through the install on a switch with outside connectivity, gather the package and dependency info… manually pull the deb’s off of the repo on whatever media you are using to transfer files to the new switch. Then copy all of the packages over and install them. It’s the hard way, but sometimes that’s the road we have to take.
Pull the package list from a switch connected to the repo:
All of the packages should be in Continue reading
How can the brightest minds help transform the Middle East for the better? The MIT SciTech Conference hoped to find answers. The annual three-day conference, which took place 19-21 April in Boston, Massachusetts, brought together students and professionals from across North America and the MENA Region. This year’s theme was “Envisioning the Future: Cities of MENA,” and included an IDEAthon on Energy, Innovation, and Infrastructure.
Many people from all over the globe attended the conference, mainly Arabs who were also successful tech entrepreneurs, leveraging the Internet to reach communities across the world. They also spoke about their innovations and inspired the young participants, who included MIT students, through panels, keynotes, ideation processes, and SciTech talks.
The first day started with a tour of MIT Labs and the launch of the IDEAthon. After initial sessions and introductions, participants were left for the night to work on their ideas. Those ended up being presented at the end of the third day to judges, with cash prizes awarded to winners so that they could turn them into reality by implementing them throughout the Arab world.
Infrastructure is a challenge in the MENA region, especially with a rapidly growing population, and the conference Continue reading
