My previous code example for IPv4 needed a bunch of modifications to work for an IPv6 address. The thing that took me the longest to figure out was that because IPv6 seems to send a lot more ICMP messages on the local network, I needed to filter the response messages to only the type I was listening for.

Because my calling routine is keeping the addresses for the hosts as strings, I’m calling each of these routines with those strings and converting them to proper addresses inside the function. I’m making a simple choice of whether it’s an IPv4 address or an IPv6 address by the fact that IPv4 addresses have “.” in them and IPv6 addresses have “:”.
I’ve written my own monitoring program to keep track of the availability of some of my machines. They register themselves in DNS using dynamic DNS protocols and occasionally change addresses. I realized that while recognizing when the address has changed is useful, I’d also like to know if the machine itself is reachable. Having code that would test the ICMP ping results directly in my code is useful, and this is what I ended up putting together after having found examples in variousl places on the web.

That works great if my address is an IPv4 address, but I required doing a lot of investigation to get a successful IPv6 address.
I upgraded my workstation for the holidays and needed to get things moved over as easily as possible.
In Visual Studio, under the tools menu, there’s an option to be able to Import and Export Settings… which got me an output file that made my new installation look mostly like my old installation.
What it didn’t transfer was the details of my connections to my Raspberry Pi devices. The following image is after I managed to get a working connection. It didn’t have anything displayed under Default Host Name etc.
I’d already run ssh-keygen on my new machine, creating a default security key on the local machine. I’d already connected via ssh to each of the hosts I regularly work on and imported the public key into the authorized_keys file and verified all appeared working.
After entering all of the details in the dialog box I got a rather unhelpful set of red boxes indicating that something had gone wrong. (192.168.0.66 and 192.168.0.67 are the same host, wired and Wi-Fi, on my local network, and I may use them interchangeably for images and text here)

I knew that the keys were good because I was using them to connect via SSH. I did some digging and realized that the physical file sizes on the new machine are larger than on the old machine. Looking at the length of the public keys themselves, I realized that my old keys were 2048 bits long, and the newly generated ones are 3072. I tried explicitly generating a new 2048 bit key with the command ssh-keygen -f id_rsa_2048 -b 2048 and using it, but I got similar results to what I was getting before. Finally, I copied my public and private key from the old machine and renamed them specifically for this usage on this machine.

That created the connection properly in Visual Studio. I went back into the Visual Studio interface, Tools->Options->Cross Platform->Connection Manager->Remote Headers Intellisense Manager and updated the headers and everything appears to be working now.
I don’t know why the keys I generated using the software on my new machine didn’t work, even when I specified the same number of bits.
I use Microsoft Visual Studio as my primary development environment. I’ve got a long-term repository that I maintain on Azure Devops at https://wimsworld.visualstudio.com/. When I create a new test project, I often create it as a subdirectory inside the main repository. That gives me version control, without the hassle of creating a new repository every time.
The downside is that when a project grows into a real program, I want to make public, I have to figure out what to do about the code. I could take a snapshot, losing all of the history, or I could jump through hoops to get the project exported from the Azure git platform and imported into the GitHub platform. I like the history of how I got from the start to where I am, so I chose to go thourgh the hoops.
I should describe this with examples. My default code repository is WimsWorld and I often create projects as directories of that, so WimsWorld/WimsConstructionCam in this case. I created this project in July, and then a couple of months later I realized I should have created the program in WimsWorld/Linux/WimsConstructionCam, so I moved it one level deeper in the repository. Git handles all of that fine and I could trace back the history of the file all the way back to creation.
Now that it’s time for me to decide I may be interested in sharing this project publicly, I looked for step by step instructions and came across a nice video doing what I wanted.
This was easiest to do on a linux box at the command line, and since I have a dev system that has its SSH keys already registered as me in both Azure Devops and GitHub I could repeat the process multiple times to get it right.
The git –filter-branch –subdirectory command got rid of all of the history except for what was in the Linux/WimsConstructionCam/ directory, which seemed right, since all the files I wanted history on currently lived in that directory.
I had previously created a repository in GitHub and this got what appeared to have history in GitHub. On closer inspection, the history only went back a couple of months, and not back to when I’d created the project. I deleted my project in github, deleted the repository directory on my local machine and started again after some research.
First I tried to manually delete everything I didn’t want from my cloned repository, move all the files to where I wanted, commit them, then connect to the new repo and push. I got a problem message about a file that was too large. Sometime in my past history, I’d managed to push a Visual Studio debug symbol database into my repository and while I’d deleted the file, I’d not deleted the history of the file from the repository. That issue was actually a good thing because it confirmed to me that method of getting the files looking the way I wanted could be leaking credentials that I might have somewhere in my private repository.
I found that I needed the git tool git-filter-repo to do what I needed to do.
wget https://raw.githubusercontent.com/newren/git-filter-repo/main/git-filter-repo
git clone WimsWorld@vs-ssh.visualstudio.com:v3/WimsWorld/WimsWorld/WimsWorld
cd WimsWorld/
git remote rm origin
python3 ~/git-filter-repo --force --path WimsConstructionCam --path Linux/WimsConstructionCam
cd Linux/WimsConstructionCam/
git mv * ../..
cd ../..
git commit .
cd ..
mv WimsWorld WimsConstructionCam
cd WimsConstructionCam/
git remote add origin git@github.com:wcbonner/WimsConstructionCam.git
git pull origin main --allow-unrelated-histories
git push origin master
Using the git-filter-repo program I was able to remove the history of everything that was outside of the original folder and the current folder. Then I moved all of the files from the current subdirectory to the repository root and committed the changes. Then I connected the repository to the new remote repository, pulled the remote, and then pushed to the remote.
A funny issue I ran into during my second try into a brand-new repository in GitHub. I’d originally created an empty repository a few weeks ago and the default branch was called master, which matched the default branch on my old repository. They’ve changed to use the current politically correct term for the default branch, and it’s named main. After I’d got both branches in GitHub, I had to merge the two so I’m working from a single branch.
After writing up my issue yesterday I posted the question on the amazon product details. I received an answer with a link to this page overnight. It references a page with several custom tuning files for their lenses. There did not seem to be a tuning file that matched the 175° FOV lens on the package I got, but there was both a 160° and a 200° version. I downloaded both files and ran a test capture with each. On initial viewing, either will work for my solution. I need to focus the lens to see if there are any noticeable differences.
I got a message about the tuning file being an older version, with pointers on how to convert it to the updated version.
WARN RPiController controller.cpp:43 This format of the tuning file will be deprecated soon! Please use the convert_tuning.py utility to update to version 2.0.
I still need to decide how I want to handle this in my automated photo processing, but having the information is hugely useful.
I’ve been playing with several cameras attached to raspberry pi recently. Getting cameras is easy right now while getting Raspberry Pi is not. I purchased this model from Amazon and have it connected to a Raspberry Pi4. I had to upgrade the unit from running Raspian Buster to Raspian Bullseye to get support for this particular camera.
Amazon Listing
I was doing some searching for red tint problems and fixing them, and it seems to be something that should be able to fix in software. Most of the fixes refer to Jetson Nano, which is not the platform I’m working with, so the fixes don’t align with my platform.
Red Tint Problem on IMX219
I still need to manually focus the lens on this camera. It’s always a frustrating process on a small lens like this because my fingers obscure the view. I’m running with camera_auto_detect=1 while https://www.arducam.com/docs/cameras-for-raspberry-pi/native-raspberry-pi-cameras/8mp-imx219-standard-camera-modules/ recommends modifying /boot/config.txt and setting both camera_auto_detect=0 and dtoverlay=imx219. exiftool reports Camera Model Name : /base/soc/i2c0mux/i2c@1/imx219@10 with the current settings. I’ve verified that using the explicit camera overlay produces the same red tint as well as having exactly the same Model Name in the exif data.
I was able to find the file /usr/share/libcamera/ipa/raspberrypi/imx219.json which may be similar to the ISP files the Jetson platforms were using. I’m still working on the red tint.
Several years ago I was trying to play with a camera on a Raspberry Pi Zero and was using FFMPEG to stream video to my PC. Now that I’m trying out the Bullseye release of Raspian, I’m attempting to use the camera tools that are installed by default.

Adding the verbose option gets some interesting information.
Each time I try higher resolution, the pi program crashes, and sometimes it leaves the pi completely nonresponsive on the network, requiring a power cycle to recover it.
I was playing with a couple of brand new H5074 devices and realized that the iOS app now includes two new charts, Dew Point, and VPD.
VPD
The new devices report as hardware version 2.00.01 firmware version 1.00.01. My older devices all report hardware version 1.00.01 and firmware version 1.01.00.
The pressure and dew point are available in both the new and old H5074 devices, but not with any of the other units I’ve got connected. (H5177 or H5075)
I’ve not been able to find details on the data. I don’t know if it’s packed into the BLE advertising data, or only available in the connected download data.
The Bluetooth communication protocol is different from any of the other devices I’ve got, but after a day of staring at raw data I was able to figure out some of the details and add support to my monitoring program https://github.com/wcbonner/GoveeBTTempLogger/ . The Bluetooth announcements from the device include both the current temperature and the set alarm temperature. I’ve not yet figured out the battery strength data. The phone app displays the battery, so I know it should be available.
There’s an orange button on one side to turn the unit on. Hold for three seconds. It will beep indicating it’s on. The LED will start flashing green, and the device will periodically send Bluetooth announcements including the temperature and alarm temperature. If you connect to the device with the phone app, the LED will switch to flashing blue, indicating that it’s in a connected state. While the device is in a connected state, it doesn’t not send out announcements. To return it to standard mode, simply exit back to the top level of the app. The app will still alarm when the probe gets to set temperature. Holding the button for three seconds when it’s on will turn it off, with beeps to confirm the change.
A nice feature of this device is that it has a magnet built in, enough to hold the device to the front of a metal oven.
Details from the Amazon listing:
Useful Smart Alerts: If temperatures fall out of your preset range, an alarm will sound, and you will get a phone alerts notification via the Govee Home app. The probe measuring range is 0° to 300°C /32° to 572°F. Note: press and hold the orange button for 3 seconds to power on.
Convenient Remote Monitoring: Tired of waiting near a hot grill, With a 230ft/70m smart Bluetooth wireless control range(no obstructions), you are free to relax and check your temperatures on your smartphone at a glance. Remember to remove the protective tip before use.
Performance Review: Detailed temperature data and easy-to-read charts are generated within 2 hours. (Charts can’t be stored/downloaded) Perfect for a quick review or an in-depth analysis of temperature performance. Improve your cooking and temperature with calibration at ±5°C.
Temperature Made Easy: 28 temperature recommendations for 14 types of foods take the hassle out of cooking. Ideal for both beginner cooks and pro chefs.
Practical Features: Temperature switching between Fahrenheit and Celcius. (The default unit is Fahrenheit) Mute alarm function and countdown timer on the Govee Home app. The magnetic back can easily be attached to the refrigerator, oven or grill, or any other metal surface. Note: Please keep the meat thermometer unit safe from heat sources and very hot surfaces to protect its internal batteries and exterior shell.
In my recent GoveeBTTempLogger Project I’ve been writing SVG files as temperature graphs. I realized I could organize the color combinations with CSS Style descriptions inside the SVG instead of fully describing each element of the graphic. I am using transparent backgrounds by default, and loading the SVG files in a simple index html file like any other image.
Playing with CSS in the HTML, I came across the ability to support dark-mode. I thought that this would be really nice for when I bring up the graphs on my phone late at night, not having everything being in a bright white background.
@media screen and (prefers-color-scheme: dark) {
body {
background-color: black;
color: grey;
}
}
I added the previous block to my style in the index.html file, which overrides the default body style of background-color: white and color: black. It works nicely at the top level, but now the black lines and text in my SVG became invisible, since now they match the background.
I tried something similar in the style for my SVG and it was working great in Chrome or Microsoft Edge. But then I realized that it doesn’t work on my phone. After realizing that it wasn’t working correctly on the phone, I decided to try switching the defaults so my default used grey, and if light mode was selected it would use black. It still didn’t work! It seems that apple is paying attention to my color-scheme selection, but doing something different from any other browser.
<style>
text { font-family: sans-serif; font-size: 12px; fill: grey; }
line { stroke: grey; }
polygon { fill-opacity: 0.5; }
@media screen and (prefers-color-scheme: light) {
text { fill: black; }
line { stroke: black; }
}
</style>
I had a friend who works primarily on a Mac test to see if the problem was specific to the iPhone, or if it occurred in Safari on the desktop as well. Yes. Apple is handling my styles differently from the other browsers I tried.
Safari on MacChrome on MacFirefox on Mac
You can see my choices displaying the way I want on Chrome and Firefox, with grey lines and text on a black background, while Safari isn’t showing the grey. Am I doing something explicitly wrong in my style that Chrome and Firefox are forgiving? Or is Apple not supporting the feature properly?
The frustrating thing is that all browsers on iPhones use the Apple rendering engine. That means there’s no way I know to get the functionality I want on my phone, where the phone uses dark mode overnight, but light mode during the day.
