SSL was developed by Netscape in the 90s and evolved into TLS. Netscape Navigator essentially evolved into Mozilla. "They've" been at it from the beginning, so it somehow seems und…

It seems to me like the underlying issue was ignoring HTTP semantics and making a state-changing link like a logout link a plain (HTTP GET) and not something like a form submission…

Make an LED blink. Then, connect an RGB LED and experiment with PWM signal generation. Then, experiment with network programming, accepting a UDP packet to the ESP32 that sets the …

Could it also be, with the advent of Satellite SOS, that Apple is starting to explore non-conventional mobile RF protocols, and that Qualcomm's product offerings are only really ge…

The GPS P(Y) and Military codes exist to (hopefully) prevent spoofing.

This probably leads to a great user experience. However, if this catches on, SMS sniffing over the air is going to really pick up! :p SMS messages are often carried over GSM contro…

Recall that Visa and Chase are major investors. It's rather difficult to "eat their lunch" with them on your board.

As one of the volunteers operating the existing Market St. WiFi and the housing project WiFi, I can say that this is definitely being discussed and evaluated, but I don't have a lo…

Well, let's just say it's an architecture Square knows well. :)

Jekyll? There's not much more than a repo and text files on the admin side, but enables super-fast blogging on light hardware.

This is _exactly_ what Aircell does in the US. I'm not sure what spectra they're using, but the bandwidth would likely be quite variable, as planes with non-directional antennas wi…

I haven't run across or know of any tutorials on this exact problem, but I think you're right that you'll end up doing a lot of the synchronization yourself. You might check out Pu…

Seems decently useful. Pretty cool that they can do asynchronous jobs in node, php, go, java, .net, python, and ruby

BOOTP and DHCP use the same ports and general packet structure, so Wireshark has the dissectors grouped. I was humored by that Wireshark screenshot. ARPs and DHCP/BOOTP requests fr…

This is the dopest WebGL application, IMO. Totally loving this, including the green mode.

In my favorite static analysis toolset (Radare, http://radare.org/ ), there's a nice feature similar to this. It "zooms" out on a big file by summarizing portions of it into chunks…

This article raises a good point, and AFAIK there's noone doing something like this on a large commercial scale. There are systems for mapping telephone numbers into DNS, like ENUM…

There are a couple of factual errors in this piece that I feel obligated to point out: 1. The root DNS server pool only hosts glue pointing TLDs to other pools of servers that admi…

Isn't this what C99's uintptr_t type tries to address?
