Administravia 030818: Added Navigation

I was asked by a reader to add categories and links for videos; I actually added three new categories, one for short videos, another for long videos, and a third for written posts. You can find these under the bottom menu item on the left. I am having a problem with the menu not showing up correctly, so I move the resources under the third menu item, as well.

Finally, I added a new archive page, which shows you all the posts in the “left” category across the three years this blog has been “in production.” I couldn’t figure out how to narrow things down so pictures and other stuff are not included, so there is more on the page than needed right now, but it’s a start.

Pushing Greater Stream Processing Platform Evolution

Today’s episode of “The Interview” with The Next Platform is focused on the evolution of stream processing—from the early days to more recent times with vast volumes of social, financial, and other data challenging data analysts and systems designers alike.

Our guest is Nathan Trueblood, a veteran of several companies like Mirantis, Western Digital, EMC, and current VP of product management at DataTorrent—a company comprised of many ex-Yahoo employees who worked with the Hadoop platform and have pushed the evolution of that framework to include more real-time requirements with Apache Apex.

Trueblood’s career has roots in high performance computing

Kate Ekanem: Promoting the Education, Literacy, and Empowerment of Girls in Nigeria

While the personal is almost always political, sometimes the person affected takes action that changes the course of history. That’s what Kate Ekanem has done. The founder of Kate Tales Foundation has spent her entire adult life promoting education, literacy, and empowerment of girls in her home country of Nigeria. And it started with herself.

“I was born into a family stuck with intense adversity, and a rural community with no access to quality education, basic health facility, reliable or no Internet facility, or social and educational opportunities,” Ekanem said. “There was no public library, no clean water, poor power supply, and streets filled with littered debris. Girls were resolving to getting pregnant [by] older men to escape the sting of poverty they were born into.”

After losing her mother at the age of two, Ekanem struggled as the only girl in a family of half-brothers. Her education took a backseat to the boys—something that she never fully accepted.

“I know what it feels like to rise in the morning and have nothing to eat. I know what it feels like to have an unending burning question, but dare not ask, because girls were not supposed to talk when Continue reading

Crypto Zealots

Is the IETF is behaving irresponsibly in attempting to place as much of the Internet’s protocols behind session level encryption as it possibly can?

Makkiya Jawed: At The Intersection of Technology and Medicine

The intersection between technology and medicine is perhaps one of the most important junctions of our time, and, in a world where access is king, many people—in fact, entire countries—can be left behind in the dust. That’s where Makkiya Jawed comes in as the director of social enterprise for Sehat Kahani in Pakistan.

The tech wiz joined forces with two doctors who launched the health tech enterprise, which circumvents Pakistan’s tradition of women having to choose family or career. It also caters to populations often overlooked by established medical communities.

“Sehat Kahani is a tele-health platform that aims to democratize healthcare via nurse-assisted video consultations by ensuring quick access, prevention and efficiency for healthcare,” Jawed explained.

Dr. Sara Saeed Khurram and Dr. Iffat Zafar, the co-founders of Sehat Kahani, both encountered the socio-cultural barriers to healthcare, but instead of giving up, they used their medical background to “democratize healthcare by building an all-female health provider network to deliver quality healthcare,” Jawed said. “They are the people who have taught me the power of team work and the importance of patience and dedication…In all honesty, whatever I have learned, they have had a major role to play in it. And the best thing is, they Continue reading

Some notes on memcached DDoS

I thought I'd write up some notes on the memcached DDoS. Specifically, I describe how many I found scanning the Internet with masscan, and how to use masscan as a killswitch to neuter the worst of the attacks.


Test your servers

I added code to my port scanner for this, then scanned the Internet:

masscan 0.0.0.0/0 -pU:11211 --banners | grep memcached

This example scans the entire Internet (/0). Replaced 0.0.0.0/0 with your address range (or ranges).

This produces output that looks like this:

Banner on port 11211/udp on 172.246.132.226: [memcached] uptime=230130 time=1520485357 version=1.4.13

Why a bare-metal cloud provider might be just what you need

Cloud services, particularly infrastructure- and platform-as-a-service, are well established, but in some cases customers demand more — more control, more access to hardware, more performance, and the ability to pick their own operating environment.In those cases, they are looking to bare-metal services, a niche that is growing quickly.As the name implies, bare metal means no software, just CPUs, memory, and storage. Customers provide all of the software from the operating system on up. That means a dedicated CPU, full access to the hardware, and freedom to run custom operating systems.According to a 2016 Markets and Markets report, the bare-metal cloud market is expected to grow from $871.8 million in 2016 to $4.7 billion in 2021, at an estimated compound annual growth rate of 40.1 percent.To read this article in full, please click here
