Funny how the house reacts to our presence…
To replace MyFitnessPal in our toolchain I am on the hunt for at least some quality food fact data.
The Open Food Facts data base seems to be one source – although in sparse and questionable quality (after first initial testing).
There is a comprehensive documentation about the fields of data supported. And there are several formats that the raw data can be downloaded in.
There are ready-made applications available as well. Definitly worth looking into further.
There is a free and well integrated OpenVPN client for iOS devices already. And as much as this one works quite well it’s also lacking some comfort features that are now made available through alternative iOS client implementations of OpenVPN.
OpenVPN is an open-source commercial software that implements virtual private network techniques to create secure point-to-point or site-to-site connections in routed or bridged configurations and remote access facilities. It uses a custom security protocol that utilizes SSL/TLS for key exchange.https://en.wikipedia.org/wiki/OpenVPN
Meet Passepartout. The iOS OpenVPN client that comes with lots of comfort features. Of main interest for me is that Passepartout is aware of the connection you’re currently using and can adopt it’s VPN tunnel status accordingly.
Passepartout is a smart OpenVPN client perfectly integrated with the iOS platform. Passepartout is the only app you need for both well-known OpenVPN providers and your personal OpenVPN servers.
The goal of this book is to document commonly-known and lesser-known methods of doing various tasks using only built-inhttps://github.com/dylanaraps/pure-bash-bible
bashfeatures. Using the snippets from this bible can help remove unneeded dependencies from scripts and in most cases make them faster. I came across these tips and discovered a few while developing neofetch, pxltrm and other smaller projects.
RTL-SDR is a very cheap ~$25 USB dongle that can be used as a computer based radio scanner for receiving live radio signals in your area (no internet required). Depending on the particular model it could receive frequencies from 500 kHz up to 1.75 GHz. Most software for the RTL-SDR is also community developed, and provided free of charge.
The origins of RTL-SDR stem from mass produced DVB-T TV tuner dongles that were based on the RTL2832U chipset. With the combined efforts of Antti Palosaari, Eric Fry and Osmocom (in particular Steve Markgraf) it was found that the raw I/Q data on the RTL2832U chipset could be accessed directly, which allowed the DVB-T TV tuner to be converted into a wideband software defined radio via a custom software driver developed by Steve Markgraf. If you’ve ever enjoyed the RTL-SDR project please consider donating to Osmocom via Open Collective as they are the ones who developed the drivers and brought RTL-SDR to life.https://www.rtl-sdr.com/about-rtl-sdr/
And since the hardware is so affordable there’s lots of software and therefore things that can be done with it.
This repo contains an annotated overlay for the Nintendo Game Boy DMG-CPU-B chip die and the extracted schematics.
This was done manually with only a few automated checks so THERE’S A HIGH RISK OF ERRORS. I’m in no way responsible if you made someone’s life depend on this and it fucked up.https://github.com/furrtek/DMG-CPU-Inside
For years now Google Maps did not allow us to download Offline Maps for Japan. It is an extremely useful feature when you are out and about and you might not yet have full mobile coverage or your plan is not set-up yet.
A week ago this was not possible and I have just now noticed that you can now select the Japan area for a custom offline map in the Google Maps app on my iPhone and on my iPad.
This is great news! Do you use the offline map feature?
This application generates a random medieval city layout of a requested size. The generation method is rather arbitrary, the goal is to produce a nice looking map, not an accurate model of a city. Maybe in the future I’ll use its code as a basis for some game or maybe not.Medieval Fantasy City Generator
The 27th Day of the Season of The Aftermath, aka The Day of the Sloth.
Curtesy of Sam Zeloof I came around the fact that I’ve got a good part of a FSTM in a cupboard here.
Apparently my choice of purchasing the HD-DVD drive for the Xbox 360 will ultimately pay off!! As we all know Bluray won that format war back in the days.
But now it seems that this below would be useable for something:
Over the life of nuclear fuel, inhomogeneous structures develop, negatively impacting thermal properties. New fuels are under development, but require more accurate knowledge of how the properties change to model performance and determine safe operational conditions.
Measurement systems capable of small–scale, pointwise thermal property measurements and low cost are necessary to measure these properties and integrate into hot cells where electronics are likely to fail during fuel investigation. This project develops a cheaper, smaller, and easily replaceable Fluorescent Scanning Thermal Microscope (FSTM) using the blue laser and focusing circuitry from an Xbox HD-DVD player.The Design, Construction, and Thermal Diffusivity Measurements of the Fluorescent Scanning Thermal Microscope (FSTM)
As mentioned, Sam Zeloof shows off the actual chip in more detail:
Streamsheets is, similar to NodeRed, a tool to step in between MQTT data coming in and something being done with it. Just other than NodeRed it is not based on flows but on a spreadsheet that executes in it’s entirety everytime a step is made.
Streamsheets are a new spreadsheet technology specifically designed for real-time data stream processing and the opportunities of digitization and the Industrial IoT.Streamsheets
SwiftUI is the new cool kid on the block when it comes to iOS/iPadOS/macOS application development.
As Apple announced SwiftUI early 2019 it’s naturally only focussing on making all the declarative UI goodness available for the Apple operating systems. No non-apple platforms in focus. Naturally.
The SwiftWebUI project is aiming to do so:
Unlike some other efforts this doesn’t just render SwiftUI Views as HTML. It also sets up a connection between the browser and the code hosted in the Swift server, allowing for interaction – buttons, pickers, steppers, lists, navigation, you get it all!
In other words: SwiftWebUI is an implementation of (many but not all parts of) the SwiftUI API for the browser.
To repeat the Disclaimer: This is a toy project! Do not use for production. Use it to learn more about SwiftUI and its inner workings.SwiftWebUI
Here’s one project that aims to develop (and explain along the way) how to create an operating system from scratch. On top of the RISC-V specifics this tutorial also aims to teach how this all can be done in a programming language called Rust.
Keep in mind that all of this is done on a baremetal system. No other software is running.
RISC-V (“risk five”) and the Rust programming language both start with an R, so naturally they fit together. In this blog, we will write an operating system targeting the RISC-V architecture in Rust (mostly). If you have a sane development environment for RISC-V, you can skip the setup parts right to bootloading. Otherwise, it’ll be fairly difficult to get started.
This tutorial will progressively build an operating system from start to something that you can show your friends or parents — if they’re significantly young enough. Since I’m rather new at this I decided to make it a “feature” that each blog post will mature as time goes on. More details will be added and some will be clarified. I look forward to hearing from you!The Adventures of OS
