Using htop to check performance on Linux

While it's one of the best tools for examining performance on Linux, htop still requires some explanation before you'll be ready to take advantage of all the data it displays. It’s an excellent tool, but you need to understand the coloring scheme, how to scroll up and down through the processes displayed, and how to change your view of what’s happening on the system.It may take some time to get used to the type of information shown and be ready to quickly notice performance problems. That, of course, means that you have to know what normal behavior looks like on your system, and this generally requires spending time with the tool on a relatively frequent basis. In other words, use htop when you’re not at all concerned about how your system is performing and you’ll likely be able to make good use of it when you are.To read this article in full, please click here

Using Custom Vagrant Boxes with netlab

A friend of mine started using Vagrant with libvirt years ago (it was his enthusiasm that piqued my interest in this particular setup, eventually resulting in netlab). Not surprisingly, he’s built Vagrant boxes for any device he ever encountered, created quite a collection that way, and would like to use them with netlab.

While I didn’t think about this particular use case when programming the netlab virtualization provider interface, I decided very early on that:

  • Everything worth changing will be specified in the system defaults
  • You will be able to change system defaults in topology file or user defaults.

RSA: Intel reference design to accelerate SASE, other security tasks

Intel has introduced a reference design it says can enable accelerator cards for security workloads including secure access service edge (SASE), IPsec, and SSL/TLS.The upside of the server cards would be offloading some application processing from CPUs, effectively increasing server performance without requiring additional server rack space, according to Intel. [ Get regularly scheduled insights by signing up for Network World newsletters. ] The announcement was made at RSA Conference 2022, and details were published in a blog post by Bob Ghaffardi, Intel vice president and general manager of the Enterprise and Cloud Division.To read this article in full, please click here

Private Access Tokens: eliminating CAPTCHAs on iPhones and Macs with open standards

Private Access Tokens: eliminating CAPTCHAs on iPhones and Macs with open standards

Private Access Tokens: eliminating CAPTCHAs on iPhones and Macs with open standards

Today we’re announcing Private Access Tokens, a completely invisible, private way to validate that real users are visiting your site. Visitors using operating systems that support these tokens, including the upcoming versions of macOS or iOS, can now prove they’re human without completing a CAPTCHA or giving up personal data. This will eliminate nearly 100% of CAPTCHAs served to these users.

What does this mean for you?

If you’re an Internet user:

  • We’re making your mobile web experience more pleasant and more private than other networks at the same time.
  • You won’t see a CAPTCHA on a supported iOS or Mac device (other devices coming soon!) accessing the Cloudflare network.

If you’re a web or application developer:

  • Know your user is coming from an authentic device and signed application, verified by the device vendor directly.
  • Validate users without maintaining a cumbersome SDK.

If you’re a Cloudflare customer:

  • You don’t have to do anything!  Cloudflare will automatically ask for and utilize Private Access Tokens
  • Your visitors won’t see a CAPTCHA, and we’ll ask for less data from their devices.

Introducing Private Access Tokens

Over the past year, Cloudflare has collaborated Continue reading

Hedge 133: Brooks Westfield and Multifactor Testing

Multi-factor testing is one of the most important jobs a vendor takes on—and one of the most underrated. Testing across all possible configurations and use cases is nearly impossible. Brooks Westbrook joins Tom Ammon and Russ White on this episode of the Hedge to talk about the complexity of multi-factor testing and some of the consequences of that complexity.
