I am back again and developing some smaller APIs for my own use.
As I am learning a new programming language and framework (SwiftUI) and for my little learning project I need to also implement a server backend. Implementing a RESTful service is quite straight-forward but for testing and UI prototyping I actually want to do some testing before really setting up the server side.
To easily test RESTful calls without actually implementing anything I found that Reqres is a quite useful tool to have in the toolbelt:
Apart from some pre-set-up API endpoints with dummy data (like users, …) it also features a request mirror service.
With that you can simply throw a JSON document into the general direction of Reqres and it will put a timestamp on it and return it right away.
User space network drivers on Linux are often used in production environments to improve the performance of network-heavy applications. However, their inner workings are not clear to most programmers who use them. ixy aims to change this by providing a small educational user space network driver, which is gives a good overview of how these drivers work, using only 1000 lines of C code. While the language C is a good common denominator, which many developers are familiar with, its syntax is often much more dicult to read than that of more modern languages and makes the driver seem more complex than it actually is.
For this thesis I created a C# version of ixy, named ixy.cs, which utilizes the more modern syntax and additional safety of the C# programming language in order to make user space network driver development even more accessible. The viability of C# for driver programming will be analyzed and its advantages and disadvantages will be discussed.
The actual implementation (with other programming languages as well) can be found here.
Boomtime 5 Aftermath: The Apostle Malaclypse the Elder’s Holyday. A wandering Wiseman of Ancient Mediterrania (“Med-Terra” or middle earth), who followed a 5-pointed Star through the alleys of Rome, Damascus, Baghdad, Jerusalem, Mecca and Cairo, bearing a sign that seemed to read “DOOM”. (This is a misunderstanding. The sign actually read “DUMB”.)
Today I learned that the Apple iPhone re-purposes the IMAP protocol to implement the voice mail feature.
By sniffing the network traffic it was possible to examine the IMAP protocol revealing username and the corresponding hashed password (which allows to repeat a successful login) and of course all voicemail files. We want to highlight, that all the voicemail files have been transferred unencrypted.
Well, it’s about time to do something about MyFitnessPal. In our family we’re using their service by the daily. But just for logging. No reports, no further features used.
But still, we were using it for quite a time now:
The service has started to roll out ads for some time now in their apps. There are only iOS / Android apps available. And a mediocre website.
Just recently they started to announce that their freeservice will restrict how many years back are going to be stored. From those 5 years we will loose 3.
In addition the whole integration has never gotten to a point where I would have decided to upgrade to the paid premium version. No functionality ever got added. No interfacing with scales, no optimizations for UI/UX, …
But they now reduce the functionalities and service and want me to cough up a bit of money:
I am not generally against subscriptions. But I am not getting 9,99 Euro of value out of the service. A shared google sheet would almost achieve parity. And the price itself is just not value based. For 2 Euro I probably would not feel the urge to move on. For 9,99 (times 2 for 2 accounts) make me move.
So I’ve sat down with my wife and we scribbled up some things we want to have in a replacement. The content and feature-set is agreed. Now I’ll throw up a prototype app.
It’ll be integrated with the MQTT scales. And with the flow we came up with we hopefully will reduce the interactions dramatically over MyFitnessPal. And it’ll never stop saving history. And I’ll learn something new.
With the synthesizers and audio processing each series and make produced a distinctive sound. Some of us want to bring these sounds back. But keeping the (old) hardware running is an increasingly difficult task.
For example: The interface used by the above mentioned Sound Blaster 16 card is the ISA bus interface. This interface was introduced in 1981 and replaced in 1993. If you want to hear how such a sound card sounds today you would have to run hardware from this time period.
But some people are working towards getting at least some authentic sound back.
In this talk, Alan Hightower takes a look at the complexities, challenges, and even current progress at integrating all of the above cores into one FPGA based ISA sound card.
This is what the concept would bring if done:
Oh that would be soooooo nice to have all these vintage sound interfaces available and to be able to actually use them for audio output.

“Fraud and corruption prevent a fair and proper expression of the public voice; that open violation of the laws are constantly occurring, caused by mobs, parties, factions and undue influence of political sects; that the citizen has not that protection of person and property which he is entitled.”

SuperCollider is a platform for audio synthesis and algorithmic composition, used by musicians, artists, and researchers working with sound. It is free and open source software available for Windows, macOS, and Linux.
SuperCollider features three major components:
scsynth, a real-time audio server, forms the core of the platform. It features 400+ unit generators (“UGens”) for analysis, synthesis, and processing.
sclang, an interpreted programming language. It is focused on sound, but not limited to any specific domain. sclang controls scsynth via Open Sound Control.
scide is an editor for sclang with an integrated help system.
HACK LIKE A PROGRAMMER IN MOVIES AND GAMES! GeekTyper was inspired by the various media where hacking is usually portrayed incorrectly. Simply randomly mash your keyboard and code will be simulated on your screen.
This is hilarious! :-) I’ve had way to much fun poking keys while trying it out…
Of course there’s also a screensaver that you can install. Recommended for office use. Not recommended on airplanes and other public spaces.
I’ve just checked with a real person. I’ve used the Visual Studio skin and typed away. Oh the aww.
