Finding and fixing typos on Linux

If you want to check a text file for typos, Linux can help.It has a couple of tools and a number of commands that can point out the errors including aspell and enchant, and I’ll share a script that I put together recently that looks for typos using the system's words file.Using aspell aspell is very clever tool that will point out typos and make it surprisingly easy to fix them. When used to make changes to a single file, it reverses the text and background colors to highlight misspelled words. You would start it with a command like this:$ aspell check myfile If aspell detects no typos, it simply exits. Otherwise, it will open with a display that contains the file text (or just the top lines depending on the length of the file) followed by a list of suggested replacement words and, below that, a list of the commands that you can run. The first typo (or suspected typo) will be displayed with the text and background colors reversed as shown below.To read this article in full, please click here

Email Routing leaves Beta

Email Routing leaves Beta
Email Routing leaves Beta

Email Routing was announced during Birthday Week in 2021 and has been available for free to every Cloudflare customer since early this year. When we launched in beta, we set out to make a difference and provide the most uncomplicated, more powerful email forwarding service on the Internet for all our customers, for free.

We feel we've met and surpassed our goals for the first year. Cloudflare Email Routing is now one of our most popular features and a top leading email provider. We are processing email traffic for more than 550,000 inboxes and forwarding an average of two million messages daily, and still growing month to month.

In February, we also announced that we were acquiring Area1. Merging their team, products, and know-how with Cloudflare was a significant step in strengthening our Email Security capabilities.

All this is good, but what about more features, you ask?

The team has been working hard to enhance Email Routing over the last few months. Today Email Routing leaves beta.

Also, we feel that this could be a good time to give you an update on all the new things we've been adding to the service, including behind-the-scenes and not-so-visible improvements.

Network Automation Considered Harmful

Some of the blog comments never cease to amaze me. Here’s one questioning the value of network automation:

I think there is a more fundamental reason than the (in my opinion simplistic) lack of skills argument. As someone mentioned on twitter

“Rules make it harder to enact change. Automation is essentially a set of rules.”

We underestimated the fact that infrastructure is a value differentiator for many and that customization and rapid change don’t go hand in hand with automation.

Whenever someone starts using MBA-speak like value differentiator in a technical arguments, I get an acute allergic reaction, but maybe he’s right.

Oracle and Nvidia expand AI partnership

Oracle and Nvidia have extended their partnership to help speed customer adoption of artificial intelligence (AI) services.As part of the deal, Oracle Cloud Infrastructure (OCI), which is Oracle’s cloud service, will beef up the infrastructure with tens of thousands of Nvidia GPUs, both the Ampere A100 currently on the market and the upcoming Hopper H100. Oracle will also add Nvidia’s AI software stack that supports AI training and deep learning.This includes an upcoming release of Nvidia AI Enterprise software with access to Nvidia’s AI development and deployment platform that provides processing engines for each step of the AI workflow, from data processing and AI model training to simulation and large-scale deployment.To read this article in full, please click here

Cleaning Out The Cruft

I spent the weekend doing something I really should have done a long time ago. I went through my piles of technology that I was going to get around to using one day and finally got rid of anything I didn’t recognize. Old access points, old networking gear, and even older widgets that went to devices that I don’t even remember owning.

Do you have one of these piles? Boxes? Corners of your office or cave? The odds are good there’s a pile of stuff that you keep thinking you’re eventually going to get around to doing something with some day. Except some day hasn’t come yet. So maybe it’s time to get rid of that pile. Trust me you’re going to feel better for getting rid of that stuff.

What to do with it? It needs to be properly recycled so don’t just toss it in the trash can. Anything with electric circuits needs to be properly disposed of so look for an electronics recycling facility. Yes, there are stories that electronics recycling isn’t all it’s cracked up to be but it’s better than polluting with e-waste everywhere.

Consider donating the devices to a trade school or other maker Continue reading

Network Break 404: Episode Not Found

This week the Network Break covers new SASE capabilities from Fortinet, new 800G hardware from Cisco that uses its homegrown ASIC, and an app from RSA for smart phones that can disable authentication if the app detects malicious behavior. Plus we cover new initiatives from the Open Compute Project, disaggregated Wi-Fi, and more tech news.

On the ‘net: Privacy and Networking

The final three posts in my series on privacy for infrastructure engineers is up over at Packet Pushers. While privacy might not seem like a big deal to infrastructure folks, it really is an issue we should all be considering and addressing—if for no other reason than privacy and security are closely related topics. The primary “thing” you’re trying to secure when you think about networking is data—or rather, various forms of privacy.

Focusing on legal defensibility is the wrong way to look at privacy, or rather the wrong end of the stick.

What are some best practices network operators can follow to reduce their risk? The simplest way to think about best practices is to think about user rights and risks at each stage of the data lifecycle.

For the final post in this series, I’ll address two topics: the privacy implications of Domain Name System (DNS) queries, and the absolute necessity of having a plan for how to respond to a breach. Let’s start with DNS.

Sidecars are Changing the Kubernetes Load-Testing Landscape

As your infrastructure is scaling and you start to get more traffic, it’s important to make sure everything works as expected. This is most commonly done through testing, with load testing being the optimal way of verifying the resilience of your services. Traditionally, load testing has been accomplished via standalone clients, like JMeter. However, as the world of infrastructure has gotten more modern, and organizations are using tools like Kubernetes, it’s important to have a modern toolset as well. With traditional load testing, you’ll commonly run into one of three major issues: Scripting load tests takes a lot of time Load tests typically run in large, complex, end-to-end environments, that are difficult to provision, as well as being expensive for production-scale infrastructure Data and realistic use cases are impossible to mirror one-to-one, unless you have production data A more modern approach is to integrate your load-testing tools directly into your infrastructure. If you’re using Kubernetes, that can be accomplished via something like an 

Tech Bytes: Using Opengear Every Day–For Disruptions And More (Sponsored)

Today on the Tech Bytes podcast we talk about how to use out-of-band management for daily networking tasks, not just when there’s a problem or crisis. Our sponsor is Opengear and we’re joined by Ramtin Rampour, Solutions Architect, to talk about use cases including zero touch provisioning, configuration, and more.

How chaos engineering can improve network resiliency

Conventional wisdom says, ‘If it ain’t broke, don’t fix it.’ Chaos engineering says, ‘Let’s try to break it anyway, just to see what happens.’The online group Chaos Community defines chaos engineering as “the discipline of experimenting on a system in order to build confidence in the system’s capability to withstand turbulent conditions in production.”Practitioners of chaos engineering essentially stress test the system and then compare what they think might happen with what actually does. The goal is to improve resiliency.For network practitioners who have spent their entire careers focused on keeping the network up and running, the idea of intentionally trying to bring it down might seem a little crazy.To read this article in full, please click here
