Action sells ‘key finder’ key fobs for as low as €2-3. These key fobs are designed to be used in conjunction with a smartphone app that can do a few things. For example, you can tell the keyfob to make a sound, which comes in handy when you misplaced your …
This took me a while to figure out, so I’m putting this here to save someone some time! I wanted to cross-compile Rust programs on my Mac to run on a Raspberry Pi (Zero in this case, but that shouldn’t matter much). The easiest way to do this is as …
The Humaneyes Vuze XR is a 2D360 and 3D180 camera in one. It can be controlled over Wi-Fi through an app from iOS or Android. It allows live streaming to Facebook and YouTube (although it seems the iOS app is pending some verification at YouTube) and allows streaming to arbitrary …
Over the fast few years I have invested great amounts of time in learning and using various programming languages. Starting out (around 1995!) in a 4GL called OMNIS (apparently still around) I quickly learned Java (from the Dummies book actually) and PHP. With Java and PHP (around 2003), I had …
In the previous post, we saw that it is possible to create programs that really only depend on the Linux kernel in order to run. Yet, we still needed some sort of Linux distribution such as Raspbian on our Raspberry Pi to actually start this program. How can we get …
For our Escape Box project, we had to come up with some kind of way to control all the various puzzles – the lights, buttons, servos, displays all need to be controlled somehow. Luckily there are various solutions available: the Arduino, the ESP8266, and the Raspberry Pi are all available …
In my opinion, the AirPods may be Apple’s best innovation since the iPhone. Being a daily user, I am still baffled by the fact that the AirPods are still (two years after their introduction) so much more convenient to use than other wireless headphones. While other headphones have issues pairing, …
The barrier of 1 Gbit/s will be reached in 2018 by power users. DSL will be too slow for most users in relatively short time. DOCSIS 3.1 provides a growth path for cable that will allow it to compete for at least another few years. Effective throughput/capacity are however still highly dependent on the amount of investment by the operator.
Having written about 80.000 lines of Swift code for Warp, I have learned a thing or two about the best way to deal with concurrency in Swift. You must not make assumptions about how callback blocks are called. Usually you want a callback function to do some work in a certain queue. Although you can design …
The Internet of Things promises to connect virtually all devices and make sensor data ubiquitously available. Instead of storing all this data in a central location, you can use a peer-to-peer network to store sensor data. Using a peer-to-peer network has several advantages. First of all, the infrastructure is ‘free’ (although in …
