Middle East Chapters Advocacy Meeting

Last month, the Chapters Advocacy Workshop for the Middle East, took place in Beirut Lebanon. The two-day event hosted Chapter leaders and representatives from  Bahrain, Egypt, Jordan, Lebanon, Saudi Arabia, Morocco, Palestine, Somalia, Syria, United Arab Emirates, and Yemen. While the focus was on MANRS (Mutually Agreed Norms for Routing Security), it also included representatives from the Blockchain SIG (Special Interest Group).

During the two days, we discussed many issues related to the Middle East Chapters and their concerns, the 2019 plan of the Middle East Bureau, the strategic vision for the Internet Society, and the 2020 planning process. We acquired feedback from the delegates on our plans and community facing processes. We had ample staff representation that contributed immensely to the workshop, including, Sally Wentworth, Salam Yamout, Konstantinos Komaitis, Sally Harvey, Nermine El Saadany, and Aftab Siddiqui.

Aftab initiated the workshop with an introductory session on MANRS. He gave a technical breakdown on what MANRS is about before moving onto a hands-on workshop. The second day opened with an introduction to the 2020 Strategic Plan, followed by a PEST analysis led by Sally. Participants gave feedback on what’s important to their Chapters and to themselves as members Continue reading

By any metric, the queries and responses that take place in the DNS are highly informative of the Internet and its use. But perhaps the level of interdependencies in this space is richer than we might think. —Geoff Huston

According to our researchers, the attackers either had access to the source code of the victims’ projects or they injected malware at the time of project compilation, meaning they were in the networks of those companies. And this reminds us of an attack that we reported on a year ago… —Kapersky

Endpoint security is a common concern among organizations, but security teams should be thinking more broadly about protecting data wherever it resides. —Kelly Sheridan

Two open source projects that have been instrumental in providing metrics for cloud native operations have merged into a single project. The fusion of Google’s OpenCensus and the Cloud Native Computing Foundation’s OpenTracing will be known as OpenTelemetry, and will be managed by the CNCF. —Joab Jackson

In a blog post published Tuesday, Google revealed that its G Suite platform mistakenly stored unhashed passwords of some of its enterprise users on internal servers in plaintext for 14 years because of a bug in the password recovery Continue reading

Will Spectrum Hunger Kill Weather Forecasting?

If you are a fan of the work we do each week with our Gestalt IT Rundown on Facebook, you probably saw a story in this week’s episode about the race for 5G spectrum causing some potential problems with weather forecasting. I didn’t have the time to dig into the details behind the story on that episode, so I wanted to take a few minutes and explain why it’s such a big deal.

First, you have to know that 5G (and many other) speeds are entirely dependent upon the amount of spectrum they can use to communicate. The more spectrum available to them, the more channels they have available to communicate. Which increases the speed they can exchange information and reduces the amount of interference between devices. Sounds simple right?

Except mobile devices aren’t the only things that are using the spectrum. We have all kinds of other devices out there that use radio waves to communicate. We’ve known for several years that there are a lot of devices in the 5 GHz spectrum used by 802.11 that interfere with wireless devices. Things like ISM radios for industrial and medical applications or government radar systems. The government has instituted Continue reading

Using Infoblox as a dynamic inventory in Red Hat Ansible Tower

Ansible_and_Infoblox-3

Do you still use spreadsheets to keep track of all your device inventory? Do you have Infoblox Appliances deployed in your infrastructure? Do you want to start automating without the burden of maintaining a static register of devices? If you answered yes to any of these questions, this blog is for you.

Operations teams often struggle to keep their Configuration Management Databases (CMDBs) up-to-date, primarily because they were not involved in the specification process to share what pieces of information are relevant to them, or even if they were, once it is put in place: Teams are not allowed to change any of their Configuration Items (CI) because they have only read-only access!

The reality is that a lot of the time when we talk about a CMDB, we are talking about tables in a database without any version control mechanism, therefore only read access is provided to end users.

The impact is that in order to perform lifecycle management (Create/Update/Decommission) of their configuration items, teams must go through a fastidious and manual process until they give up changing CIs (Configuration Items) in the CMDB and just leave everything as it is. What happens next? Different teams start Continue reading

If You Worry About 768K Day, You’re Probably Doing Something Wrong

A few years ago we “celebrated” 512K day - the size of the full Internet routing table exceeded 512K (for whatever value of K ;) prefixes, overflowing TCAMs in some IP routers and resulting in interesting brownouts.

We’re close to exceeding 768K mark and the beware 768K day blog posts have already started appearing. While you (RFC 2119) SHOULD check the size of your forwarding table and the maximum capabilities of your hardware, the more important question should be “Why do I need 768K forwarding entries if I’m not a Tier-1 provider”

Compress objects, not cache lines: an object-based compressed memory hierarchy

Compress objects, not cache lines: an object-based compressed memory hierarchy Tsai & Sanchez, ASPLOS’19

Last time out we saw how Google have been able to save millions of dollars though memory compression enabled via zswap. One of the important attributes of their design was easy and rapid deployment across an existing fleet. Today’s paper introduces Zippads, which compared to a state of the art compressed memory hierarchy is able to achieve a 1.63x higher compression ratio and improve performance by 17%. The big idea behind zippads is simple and elegant, but the ramifications go deep: all the way down to a modified instruction set (ISA)! So while you probably won’t be using Zippads in practice anytime soon, it’s a wonderful example of what’s possible when you’re prepared to take a fresh look at “the way we’ve always done things.”

The big idea

Existing cache and main memory compression techniques compress data in small fixed-size blocks, typically cache lines. Moreover, they use simple compression algorithms that focus on exploiting redundancy within a block. These techniques work well for scientific programs that are dominated by arrays. However, they are ineffective on object-based programs because objects do not fall neatly Continue reading
