Developing Community Networks in Northern Brazil: Strengthening Marginalized Communities

Today’s guest author is Carlos Afonso, executive director of Instituto Nupef.

Our aim is to contribute to the growth and improvement of community networks policies and practices in Brazilian rural areas by strengthening marginalized movements and communities. Our project is supported by the Internet Society Beyond the Net Funding Programme and developed by the Brazil Chapter in partnership with the Instituto Nupef (Center of Research, Studies, and Learning) as well as the involvement of local communities.

Nupef’s role helps to build a statement of needs perceived by the communities involved and an evaluation of infrastructural conditions in the area.  It takes note of conditions for sustainable maintenance of the network; training for local people; constitution of a cooperative-like structure to operate, maintain, and further develop the network; as well as basic training on content development, user security, and privacy issues.

Although access to broadband Internet has been growing in Brazil, there is still a huge gap in marginalized regions and populations, especially in rural areas in the North and Northeast. This is the case of the Quilombola communities living in rural areas with very few telecommunications, and where over 300 thousand women make their living from gathering babaçu palm tree Continue reading

Investigator finds no evidence of spy chips on Super Micro motherboards

An investigation by an outside firm that specializes in all manner of corporate investigations has found no evidence that motherboards sold by Super Micro Computer but made in China had secret chips implanted in them for spying or backdoor access.Like every other OEM, Super Micro, based in San Jose, California, sources many of its components from China. There have been issues raised in the past about Chinese-owned hardware companies. IBM faced some initial resistance when it sold its x86 server business to Lenovo, especially since many government agencies — including the Defense Department — used IBM hardware.But Super Micro was rocked last October when Bloomberg BusinessWeek ran a lengthy feature article alleging that tiny chips were being secretly stashed on Super Micro motherboards for the purpose of providing backdoors for hackers to illegally access the servers.To read this article in full, please click here

Traffic Acceleration with Cloudflare Mobile SDK

Traffic Acceleration with Cloudflare Mobile SDK

We’re excited to announce early access for Traffic Acceleration with Cloudflare Mobile SDK. Acceleration uses novel transport algorithms built into the SDK to accelerate apps beyond the performance they would see with TCP. Enabling Acceleration through the SDK reduces latency, increases throughput, and improves app user experiences.

A year ago, we launched Cloudflare Mobile SDK with a set of free features focused on measuring mobile app networking performance. Apps are dependent on network connectivity to deliver their app’s user experiences, but developers have limited visibility into how network connectivity is impacting app performance. Integrating the Mobile SDK allows developers to measure and improve the speed of their app’s network interactions.

How it works

Mobile applications interact with the Internet to do everything — to fetch the weather, your email, to step through a check out flow. Everything that makes a smartphone magical is powered by a service on the Internet. How quickly those network interactions happen is dictated by two things: how large the payloads are for the given request/response, and what the available link bandwidth is.

Payload size is mostly application specific: a shopping app is going to request product images and similar medium sized assets, while a stock Continue reading

Lessons learned from Black Friday and Cyber Monday

 

If you’re a consumer-facing business, Black Friday and Cyber Monday are the D-Day for IT operations. Low-level estimates indicate that upwards of 20% of all revenues for companies can occur within these two days. The stakes are even higher if you’re a payment processor as you aggregate the purchases across all consumer businesses. This means that the need to remain available during these crucial 96 hours is paramount.

My colleague, David, and I have been working the past 10 months preparing for this day.  In January 2018 we started a new deployment with a large payment processor to help them build out capacity for their projected 2018 holiday payment growth. Our goal was to create a brand new, 11 rack data center to create a third region to supplement the existing two regions used for payment processing. In addition, we helped deploy additional Cumulus racks and capacity at the existing two regions, which were historically built with traditional vendors.

Now that both days have come and gone, read on to find out what we learned from this experience.

Server Interop Testing

Payment processing has most of its weight on the payment applications running in the data center. As with Continue reading

How my team wrote 12 Cloudflare apps with fewer than 20 lines of code

How my team wrote 12 Cloudflare apps with fewer than 20 lines of code

This is a guest post by Ben Ross. Ben is a Berkeley PhD, serial entrepreneur, and Founder and CTO and POWr.io, where he spends his days helping small businesses grow online.

I like my code the same way I like my team of POWr Rangers… DRY.

And no, I don’t mean dull and unexciting! (If you haven’t heard this acronym before, DRY stands for Don’t Repeat Yourself, the single most important principle in software engineering. Because, as a mentor once told me, “when someone needs to re-write your code, at least they only need to do it once.”)

At POWr, being DRY is not just a way to write code, it’s a way of life. This is true whether you’re an Engineer, a Customer Support agent, or an Office Manager; if you find you’re repeating yourself, we want to find a way to automate that repetition away. Our employees’ time is our company’s most valuable resource. Not to mention, who wants to spend all day repeating themselves?

We call this process becoming a Scaled Employee. A Scaled Employee leverages their time and resources to make a multifold impact compared to an average employee in their Continue reading

Podcast: The State of Packet Forwarding

Enterprise network architectures are being reshaped using tenets popularized by the major cloud properties. This podcast explores this evolution and looks at the ways that real-time streaming telemetry, machine learning, and artificial intelligence affect how networks are designed and operated.

Computers could soon run cold, no heat generated

It’s pretty much just simple energy loss that causes heat build-up in electronics. That ostensibly innocuous warming up, though, causes a two-fold problem:Firstly, the loss of energy, manifested as heat, reduces the machine’s computational power — much of the purposefully created and needed, high-power energy disappears into thin air instead of crunching numbers. And secondly, as data center managers know, to add insult to injury, it costs money to cool all that waste heat.For both of those reasons (and some others, such as ecologically related ones, and equipment longevity—the tech breaks down with temperature), there’s an increasing effort underway to build computers in such a way that heat is eliminated — completely. Transistors, superconductors, and chip design are three areas where major conceptual breakthroughs were announced in 2018. They’re significant developments, and consequently it might not be too long before we see the ultimate in efficiency: the cold-running computer.To read this article in full, please click here
