Good (and bad news): the general consensus in the web developer community is that any and every website should be HTTPS by default. Why?

As if 2016 wasn’t long enough, this year, a leap second will cause the last day of December to be one second longer than normal. But don’t worry, we’ve built support for the leap second into the time servers that regulate all Google services.
Data harvesters are reaching into virtually every part of your digital life through the little-known surveillance hardware industry.
A quick look at how the movie The Exorcist from 1973 has links to the late great Alan Turing via Mike Oldfield’s album Tubular Bells, Scotland and Amateur Radio. It’s Halloween so figured why not throw some horror in the mix.
I think I've mentioned occasionally that various devices, mostly cellular modems, just use the Hayes or AT command set. Recently I obtained a GPS tracking device (made by Queclink) that is, interestingly, fully configured via the Hayes command set. It's an example of a somewhat newer trend of converging the…
While hackers do good most of the time, we occasionally do evil and play a prank. The ESP8266, unlike JSON , allows me to do evil. Thus, I programmed the microcontroller for an evil purpose: slow down the WiFi.

This post is going to be a bit different from my usual posts. It’s still about computers, but it’s about a different type of computer: the computer modules in my 2009 Dodge Ram 1500 pickup. Vehicles these days have lots of computers in them. I’ve historically been afraid to mess too much with them in fear of screwing…

Over the last month, we’ve been watching some of the largest distributed denial of service (DDoS) attacks ever seen unfold. As CloudFlare has grown we've brought on line systems capable of absorbing and accurately measuring attacks.

We locate web content using special addresses called URLs. We are all familiar with addresses like https://google.com. Sometimes, URLs can get long and they can become difficult to read. Thus, we might be tempted to format them like so in HTML using newline and tab characters, like so: <a…

I really love ping! It is easy to use and directly reveals whether the network works or not. Refer to Why Ping is no Security Flaw! (But your Friend) and Advanced Tracerouting . At least outgoing pings (from trust to untrust) should be allowed without any security concerns. However, many companies are denying these…

When you hear the term, you should picture an hourglass with M things on one side, N on the other, and an important concept in the middle.
I attended a TCP/IP Geeks Stockholm meetup yesterday and did a talk about HTTP/2. Below is the slide set, but as usual it might not be entirely self explanatory... HTTP/2 - for TCP/IP Geeks Stockholm from Daniel Stenberg
