What Kind of Design?

In this short video I work through two kinds of design, or two different ways of designing a network. Which kind of designer are you? Do you see one as better than the other? Which would you prefer to do, are you right now?

Aruba rolls out security fabric designed for IoT and the digital era

Aruba, a Hewlett Packard Enterprise Company, is best known for its outstanding business-grade Wi-Fi products. What’s less well known about Aruba is that it has always had excellent security products. In fact, I’ve often described the company as a security vendor dressed up as a Wi-Fi vendor, as Aruba and security have gone hand in hand like the New England Patriots and winning. However, Aruba’s security positioning has always been tactical rather than strategic because its products were used for specific purposes, such as end point protection or wireless security. That shifted this week at APAC Atmosphere in Macau when the company introduced its 360 Security Fabric, which enables it to provide end-to-end security to address the needs of a world that is becoming increasingly digitized. To read this article in full or to leave a comment, please click here

Evolution of data structures in Yandex.Metrica

Yandex.Metrica is the world's second largest web analytics system. Metrica takes in a stream of data representing events that took place on sites or on apps. Our task is to process this data and present it in an analyzable form.


Processing the data in itself is not a problem. The real difficulty lies in trying to determine what form the processed results should be saved in so that they are easy to work with. During the development process, we had to completely change our approach to data storage organization several times. We started with MyISAM tables, then used LSM-trees and eventually came up with column-oriented database, ClickHouse. In this article I'll explain what led us to settle on this last option.

Yandex.Metrica was launched in 2008 and has now been running for more than nine years. Every time we changed our approach to data storage in the past it was because a particular solution proved inefficient: either there was insufficient performance reserve, or the solution was unreliable, or it used too many computational resources, or it just did not allow us to implement what we needed to.

The old Yandex.Metrica for websites has more than 40 "fixed" Continue reading

W3C DRM appeal fails, votes kept secret

Earlier this summer, the World Wide Web Consortium (W3C) — the organization responsible for defining the standards that make up the Web — decided to embrace DRM (aka "EME") as a web standard. I wasn’t happy about this. I don’t know many who were.Shortly after that, the W3C agreed to talk with me about the issue. During that discussion, I encouraged the W3C to increase their level of transparency going forward — and if there is an appeal of their DRM decision, to make that process completely open and visible to the public (including how individual members of the W3C vote on the issue).To read this article in full or to leave a comment, please click here

Worth Reading: Why you should have a CAA DNS record

This Friday, all certificate authorities will have to honor a Domain Name System (DNS) record that allows HTTPS website owners to restrict who can issue SSL certificates for their domain names. It’s a long-needed defense against the issuance of fraudulent certificates, a security risk that domain owners had few protections for until now. The Problem: There are tens of certificate authorities (CAs) trusted in browsers and operating systems and any one of them can theoretically issue a valid SSL certificate for any website on the internet. Furthermore, many of these certificate authorities have subordinate CAs and resellers that are operated by separate organizations and which can also issue SSL certificates to end users. —Lucian Constantin @ The New Stack

IDG Contributor Network: Ethernet frames and packets: what’s the difference?

When discussing Ethernet data, the terms frame and packet are often used interchangeably. Frames and packets are the electronic containers that carry our data from point-to-point by navigating LANs and WANs and, as they both serve similar functions, their differences are often misunderstood.So what’s the difference? To simplify matters, imagine frames and packets as envelopes of information that are going to be sent from one person to another. The key difference between a frame and a packet is how they encapsulate the information and that depends on where the information is being sent.Frames explained Imagine a company with inter-department mail where a person can send documents to another person within their private/local organization. The contents are placed in an internal envelope and the sender writes their name and department in the “From” field, then writes the recipient’s name and department in the “To” field. To read this article in full or to leave a comment, please click here

Some Q&A About the Migration to Hugo

As you may already know, I recently completed the migration of this site from GitHub Pages (generated using Jekyll) to S3/CloudFront and Hugo for static site generation. Since then, I’ve talked with a few readers who had additional questions about the site migration. I thought others might have the same questions, so I decided to gather the most common questions here and share the answers with everyone.

(For those who need a quick primer on how the site is set up/served, refer to this post.)

I’ll structure the rest of this post in a “question-and-answer” format.

Q: Why migrate away from Jekyll?

A: Some of this is tied up with GitHub Pages (see the next question), but the key things that drove me away were very slow build times (in excess of five minutes), limited troubleshooting, dealing with Ruby dependencies in order to run local Jekyll builds (needed to help with troubleshooting), and limited functionality (due in part to GitHub Pages’ restrictive support for plugins).

Q: Why migrate away from GitHub Pages?

A: If you’re happy with Jekyll (and it’s a fine static site generator for lots of folks), having it integrated on the backend with GitHub Pages Continue reading

5 Ways to Secure Wi-Fi Networks

Wi-Fi is one entry-point hackers can use to get into your network without setting foot inside your building because wireless is much more open to eavesdroppers than wired networks, which means you have to be more diligent about security.But there’s a lot more to Wi-Fi security than just setting a simple password. Investing time in learning about and applying enhanced security measures can go a long way toward better protecting your network. Here are six tips to betters secure your Wi-Fi network.Use an inconspicuous network name (SSID) The service set identifier (SSID) is one of the most basic Wi-Fi network settings. Though it doesn’t seem like the network name could compromise security, it certainly can. Using a too common of a SSID, like “wireless” or the vendor’s default name, can make it easier for someone to crack the personal mode of WPA or WPA2 security. This is because the encryption algorithm incorporates the SSID, and password cracking dictionaries used by hackers are preloaded with common and default SSIDs. Using one of those just makes the hacker’s job easier.To read this article in full, please click here
