Nvidia co-founder and chief executive officer, Jensen Huang, would be the first one to tell you that the graphics chip maker was an unintended innovator in supercomputing, that what the engineers who created the first Nvidia GPUs were really trying to do was enable 3D video games. …

Edge computing offers multiple benefits in an IoT environment, but one thing you don't want to be on the edge about is edge computing security.
And here we are with an another guide that gives answers to the question such as "what Bitcoin is" or "how does it work" and how Bitcoin is related to online gambling. It is definitely worth to read and I hope you will enjoy it as much as I did.

Some (anti)patterns of network industry are way too predictable: every time there’s a new technology marketers start promoting it as the solution for every problem ever imagined. VXLAN was quickly touted as the solution for long-distance vMotion, and now everyone is telling you how to use VXLAN with EVPN to stretch VLANs across multiple data centers.
Does that make sense? It might… based on your requirements and features available on the devices you use to implement the VXLAN/EVPN fabric. We’ll cover the details in a day-long workshop in Zurich (Switzerland) on December 5th. There are still a few places left, register here.
It has been over three months since I started as a marketing intern at Cloudflare. Even before joining the Cloudflare team, I enjoyed reading the technical blog posts about Cloudflare’s use cases and solutions, as well as the inclusive and creative culture. Educating the world about the threats we face on the Internet is something that I found truly valuable. I figured that I would give my own spin on what it’s like to join and work at Cloudflare by writing a blog post too.
Before starting as a freshman in university, I created an online portfolio for my photography. It has been a passion of mine for about 9 years. I tried a multitude of platforms but none afforded me the aesthetic control that I wanted. The only solution was to build and host my own site. I started learning HTML/CSS, a bit of JavaScript and jQuery and so on.
This led to me using the Koken CMS, and hosting it on DigitalOcean in a Docker container. What was left was SSL/TLS encryption and a CDN (my friends in Europe find the loading times unbearable). Continue reading
Continuum: a platform for cost-aware low-latency continual learning Tian et al., SoCC’18
Let’s start with some broad approximations. Batching leads to higher throughput at the cost of higher latency. Processing items one at a time leads to lower latency and often reduced throughput. We can recover throughput to a degree by throwing horizontally scalable resources at the problem, but it’s hard to recover latency. In many business scenarios latency matters, so we’ve been seeing a movement overtime from batching through micro-batching to online streaming.
Continuum looks at the same issues from the perspective of machine learning models. Offline (batch) trained models can suffer from concept drift (loss of accuracy over time) as a result of not incorporating the latest data. I.e., there’s a business cost incurred for higher latency of update incorporation. Online models support incremental updates. Continuum determines the optimum time to retrain models in the presence of incoming data, based on user policy (best effort, cost-aware, or user-defined). There’s some great data here about the need for and benefit of continual learning, and a surprising twist in the tale where it turns out that even if you can afford it, updating the model on Continue reading

NCLU is the always helpful Network Command Line Utility. It’s a command interface for our products and platforms that’s designed to provide direct, simple access to network configuration information. Thus, NCLU supports both inspection and modification of Cumulus Networks configuration data. Better yet, NCLU is easy to customize for local environments and naming conventions using its net example facility.
In general, NCLU enables users at the command line to learn about current configurations, and make changes or additions to such configurations. NCLU reports on Interfaces and can provide information about IP addresses, VLANs, Access controls, Trunking, STP, and more. At the routing level, NCLU provides information about Border Gateway Protocol (BGP) and Open Shortest Path First (OSPF) routing protocol settings and configurations. NCLU also offers information about services, including hostnames, NTP (Network Time Protocol), Timezone, and so on.
NCLU also includes comprehensive, context-sensitive help. Starting with the basic net command, users can learn about the various sub-commands available to them. Similarly, entering net <sub-command-name> provides help for that specific sub-command. This is how Cumulus (and other forms of) Linux delivers help information for users of complex commands like net.
In addition, NCLU commands provide control over configuration staging, Continue reading
One thing’s for sure: The world of networking and networking administration is quickly changing. Part of this change is an evolution from old-school, proprietary centralized networking to more open options. This evolution has several different effects on the way network designers, administrators and engineers design and operate the network. This blog will focus on the different options available for modern automation, and how the Cumulus Linux approach provides the greatest amount of flexibility.
It wasn’t too long ago that the few big networking vendors had an almost unbreakable grip on organizational networking implementations, and correspondingly, with the way these implementations were managed. For most, this included the configuration of the various types of networking equipment using a command-line interface (CLI) and proprietary commands. Automating these types of solutions most often required either an offering developed by the vendors themselves, or the use of an application programming interface (API) written to interface with their products.
The question is whether this was a good thing or not. Generally, vendor-specific solutions have their advantages because they’re able to interface closely with the specific device code and take advantage of communications between the device coding team and the tools coding team.
