Collaborate Disseminate
[P B Richards] and [Aaron Flin] were bemoaning the resource hunger of modern JavaScript environments and planned to produce a system that was much stingier with memory and CPU, that …read more Continue reading Squish That Stack With Rampart
As we returned from Supercon 2022, we noticed many airlines offer free in-flight messaging. While the messages are handy for complaining about the seat size, it isn’t quite as exciting …read more Continue reading Dial-Up Internet Over WhatsApp
I published the following diary on isc.sans.edu: “Keep an Eye on WebSockets“: It has been a while that I did not spot WebSockets used by malware. Yesterday I discovered an interesting piece of Powershell. Very small and almost undetected according to its Virustotal score (2/54). A quick reminder for those
The post [SANS ISC] Keep an Eye on WebSockets appeared first on /dev/random.
[Renzo Mischianti] got himself a Chinese 3D printer, specifically a FlyingBear Ghost 5. (Cracking name, huh?) He was more than a little irritated with the fact that whilst the controller, …read more Continue reading 3D Printering: Adding A Web Interface Where There Was None Before
You might have recently heard that eBay is performing port scanning, while online shoppers are visiting their website. At first glance, it will probably sound a bit strange, as port scanning is an internal network action. As such, it is designed to det… Continue reading Why and How are Enterprise Companies, Like eBay, Actively Port-scanning End-users’ Computers From Their Websites
Love it or hate it, for many people embedded systems means Arduino. Now Arduino is leveraging its more powerful MKR boards and introducing a cloud service, the Arduino IoT Cloud. The goal is to make it simple for Arduino programs to record data and control actions from the cloud.
The program is in beta and features a variety of both human and machine interaction styles. At the simple end, you can assemble a dashboard of controls and have the IoT Cloud generate your code and download it to your Arduino itself with no user programming required. More advanced users can …read more
It used to be that Web browsing was simple. You asked a server for some text, which was duly sent, and then formatted by your browser. Now a web page is as likely to be a full-blown application that is reading mail, editing text, or lots of other things and may use WebSockets to create a back channel to the server. Thanks to affordable hardware like the ESP8266 one of those things a modern web browser can do is sense and control the real world. [Acrobotic] has an interesting video about using WebSockets to allow a browser to talk to …read more

Everyone’s favourite IOT module, the ESP8266, is often the go-to choice for any project that needs quick and cheap control over the web. [Andi23456] wanted to control his quadcopter using the luxury of his mobile phone and thought permanently tethering an ESP12-E module to the quadcopter was exactly what he required.
The ESP8266, really showcasing its all-round prowess, hosts both a web server for a HTML5 based joystick and a Websockets server so that a client, such as a phone, could interact with it over a fast, low latency connection. Once the ESP8266 receives the input, it uses interrupts to …read more
In the process of making a homemade Mech Combat game that features robot-like piloted tanks capable of turning the cockpit independent of the direction of movement, [Florian] realized that while the concept was intuitive to humans, implementing it in a VR game had challenges. In short, when the body perceives movement but doesn’t feel the expected acceleration and momentum, motion sickness can result. A cockpit view that changes independently of forward motion exacerbates the issue.
To address this, [Florian] wanted to use a swivel chair to represent turning the Mech’s “hips”. This would control direction of travel and help provide …read more
