It Always Takes Too Long

It always takes longer to find a problem than it should. Moving through the troubleshooting process often feels like swimming in molasses—it’s never fast enough or far enough to get the application back up and running before that crucial deadline. The “swimming in molasses effect” doesn’t end when the problem is found out, either—repairing the problem requires juggling a thousand variables, most of which are unknown, combined with the wit and sagacity of a soothsayer to work with vendors, code releases, and unintended consequences.

It’s enough to make a network engineer want to find a mountain top and assume an all-knowing pose—even if they don’t know anything at all.
The problem of taking longer, though, applies in every area of computer networking. It takes too long for the packet to get there, it takes to long for the routing protocol to converge, it takes too long to support a new application or server. It takes so long to create and validate a network design change that the hardware, software and processes created are obsolete before they are used.

Why does it always take too long? A short story often told to me by my Grandfather—a farmer—might help.

Evolution of search engines architecture – Algolia New Search Architecture Part 1

 

What would a totally new search engine architecture look like? Who better than Julien Lemoine, Co-founder & CTO of Algolia, to describe what the future of search will look like. This is the first article in a series.


Search engines, and more generally, information retrieval systems, play a central role in almost all of today’s technical stacks. Information retrieval started in the beginning of computer science. Research accelerated in the early 90s with the introduction of the Text REtrieval Conference (TREC). After more than 30 years of evolution since TREC, search engines continue to grow and evolve, leading to new challenges.

In this article, we look at some key milestones in the evolution of search engine architecture. We also describe the challenges those architectures face today. As you’ll see, we grouped the engines into four architecture categories. This is a simplification, as there are in reality a lot of different engines with various mix of architectures. We did this to focus our attention on the most important characteristics of those architectures.

Decentralized Chat: Matrix Offers Red Pill to Slack Users

One of the most interesting internet trends of 2021 is the experimentation going on with decentralized technologies. We’re seeing a blossoming of open source, decentralized internet applications — many of them attempting to provide alternatives to big tech products. Privacy breaches, misinformation, black box algorithms, lack of user control — these are just some of the problems inherent in the proprietary, centralized social media and communications products of Facebook, Twitter, Apple, Google, and others. The question is: can decentralized applications be a panacea? Richard MacManus Richard is senior editor at The New Stack and writes a weekly column about web and application development trends. Previously he founded ReadWriteWeb in 2003 and built it into one of the world’s most influential technology news and analysis sites. In today’s column, I look at an emerging decentralized, open standard for real-time communications: defined as “an open standard for interoperable, decentralized, real-time communication over IP.” Products built on top of Matrix could provide an alternative to using commercial Instant Messaging products like Slack or WhatsApp.

Thought Experiment: How Did Zoom’s Infrastructure Keep Us Connected?

Helping Keep Governments Safe and Secure

Today, we are excited to share that Cloudflare and Accenture Federal Services (AFS) have been selected by the Department of Homeland Security (DHS) to develop a joint solution to help the federal government defend itself against cyberattacks. The solution consists of Cloudflare’s protective DNS resolver which will filter DNS queries from offices and locations of the federal government and stream events directly to Accenture’s analysis platform.

Located within DHS, the Cybersecurity and Infrastructure Security Agency (CISA) operates as “the nation’s risk advisor.”1 CISA works with partners across the public and private sector to improve the security and reliability of critical infrastructure; a mission that spans across the federal government, State, Local, Tribal, and Territorial partnerships and the private sector to provide solutions to emerging and ever-changing threats.

Over the last few years, CISA has repeatedly flagged the cyber risk posed by malicious hostnames, phishing emails with malicious links, and untrustworthy upstream Domain Name System (DNS) resolvers.2 Attackers can compromise devices or accounts, and ultimately data, by tricking a user or system into sending a DNS query for a specific hostname. Once that query is resolved, those devices establish connections that can lead to malware downloads, phishing websites, Continue reading

SSD prices expected to spike as Intel, AMD ship new server processors

Prices of enterprise-grade solid-state drives are likely to jump in the coming months, perhaps by as much as 15% over current SSD prices, says TrendForce, a Taiwanese market research firm that focuses on the memory market.In a rare and no doubt unintentional move, Intel and AMD are on a path to begin shipping new processors at roughly the same time: Intel with its Ice Lake generation of Xeon processors and AMD with its Milan processors. You can expect HP Enterprise, Dell Technologies, Lenovo, Super Micro, and every other OEM to unleash a raft of servers at the same quarter as they usually do.To read this article in full, please click here

Is your network AI as smart as you think?

Network-operations types tell me that, in the future, AI is going to manage their networks. They also tell me that their vendors told them that very same thing. The good news is that’s sort-of-true. The bad news is the same; with emphasis on the qualifier “sort-of”. To get the most from AI network management, you have to navigate out of that hazy “sort-of” zone, and you do it by thinking about ants and farmers.Ants can build wonderfully complex anthills, with all manner of interconnecting tunnels and levels. Do the worker ants have some mighty engineer-ant directing this process? Nope. Each of them is single-mindedly performing its own simple task, and instincts program them. There is in fact an ant-engineer, but it’s their own DNA that’s organized their work to accomplish the goal. That’s a bit like how most network AI works.To read this article in full, please click here

How Pensando Redefines Networking with P4 DSC (SmartNIC) – Rolf Schaerer, Systems Engineer @ Pensando Systems

In this episode Rick and Melchior invited Rolf Schaerer from Pensando Systems and ask him all how Pensando redefines the Netwok Server Edge.

“A New Way of Thinking About Next-Gen Cloud Architectures” leveraging a custom, programmable P4 processor Pensanso refers to as Capri. Capri is optimized to execute a software stack delivering cloud, compute, network, storage, and security services at cloud scale. Capri is easily installed in any standard server via the Pensando Distributed Services Card (DSC). The DSC provides software-defined services at the server edge, eliminating an assortment of discrete appliances throughout the data center and simplifying IT operations.

pygnmi 10. Rapid and Reliable Network Testing with Pytest, Pygnmi, and OpenConfig

Hello my friend,

Talking to some our partners, they mentioned that they are extensively using the unit tests python libraries for the development of the software in Python. They are creating their applications in Django framework; therefore, they are using a built-in Django testing library, which is based on Python’s standard unittest. We start looking, how we can use that ourselves…

Can This Help with Automated Network Assurance?

What do we, network engineers, do to quickly check that our network devices are reachable? We do ping. However, is that really good enough to check that your devices are OK? The one could say: I don’t even use a ping for that, as I rely on my NMS. This is also a good answer. In the same time, though, the vast majority of the NMS doesn’t contain all the details of network devices configuration and their operational data: e.g. all the details of OSPF and Continue reading
