In the past weeks, I have noticed hearham.com repeater listing gets many requests from Android devices. Furthermore, many ham radio people already have an Android phone and are still waiting on their Librem Phone to ship. So I started an Android port of the Linux open-data repeater app, Repeater-START.Continue reading “Announcing Repeater-START Amateur radio app for Android”
Human pose estimation with Python and Gluoncv
Human pose estimation is something useful for robotics/programming as you can see what position a person is in a picture. For last weekend’s Hackrithmitic I did an experiment for fun using computer vision pose estimation. To start with I found several possibilities with available libraries:
- Tensorflow js has been used to say, don’t touch your face, but it takes a massive amount of cpu.
- Openpose is a popular one, only licensed for noncommercial research use, and there is a Opencv example for it that doesn’t quite show how to use it.
- AlphaPose is supposedly faster and has a more clear license and possibility for commercial use – if you want that as a possibility. I checked out the install instructions and worked but for “python3” instead of “python”. It also misses obvious step of installing cuda for your Nvidia system before running.
- GluonCV is another, which seems more user friendly. This one I was able to get running in a few minutes with their example:
Autocorrect Remover is now up on Chrome Web Store
The Autocorrect Remover was approved to be shown on Google Chrome webs store! Now all students or teachers can access the autocorrect remover that I built with a friend recently. One month after publishing, it appears no changes on Google Docs have broken it, which is a good sign 🙂Continue reading “Autocorrect Remover is now up on Chrome Web Store”
Slide rule enters the 21st century
Some time ago I came across this online tool in a newsletter article – this is a very cool slide-rule-emulator that will not just let you move two slides, but actually slide it for you as you run an equivalent digital calculator calculation to the right!
If you haven’t ever used a slide rule before, it works on properties of logarithms, and the principle that log(a)+log(b) = log(a*b). Now it wouldn’t be very interesting to just have two normal rulers together, as sliding and adding would just let you do problems like 5+5 = 10 or 50+50 = 100 if you scale the numbers. With logarithmic scale, the spacings are off and it allows you to do multiplication in adding the numbers.Continue reading “Slide rule enters the 21st century”
Matt Parker explains professional online videography

Librem announces Anbox working on Librem 5 phone
Yesterday Librem announced in a blog post that the Android compatibility layer, Anbox, is runnable in the Librem 5 Linux phone. They reportedly had to fix a few bugs, and they show a screenshot of a listing of apps – it is odd to notice that most apps shown (Firefox, Music, Camera…) really should have a native Linux application that works.Continue reading “Librem announces Anbox working on Librem 5 phone”
Hacktoberfest is coming up!
Hacktoberfest is coming up, online this time (well, the core of hacktoberfest always has been online collaboration…), and there are several projects I’ve worked on that welcome contributions:
- Repeater-START – a useful tool for any ham radio enthusiast looking for repeaters.
- Hearham Listener – also connects to hearham.com, this is an experimental listener to listen for audible callsigns on the ham radio.
- Anti-Auto-correct, very useful for students in these remote times!
- iosTransferGUI – I had used this for transferring files to iDevices, on Ubuntu.
- Pylympus – for certain Olympus cameras with wifi-remote, a pure Python remote program.
There are many others and probably plugins or software you use every day that may need contributions or bug fixes, so with less than a month before the start, be thinking about what projects you might contribute to! Check out the full details at https://hacktoberfest.digitalocean.com/events
Removing old PPA from Ubuntu for stability and latest features
Once in awhile a package hangs out at an old version even after a system upgrade or two. This can cause odd things like that software portion not working like it should. In my case, an old salbabix ios PPA that was long defunct as Ubuntu 18.04 and later have no problem just plugging in updated iOS devices.Continue reading “Removing old PPA from Ubuntu for stability and latest features”
Google sued over Android’s tracking, revises options.
Last month we heard Google was getting sued again for collecting location data tied to user accounts. This is yet another reason it’s good to keep your Google account separate, away from your Google device if you have one. But last week Google announced that they will be changing this, auto deleting data after 18 months… but only for new Google accounts.Continue reading “Google sued over Android’s tracking, revises options.”
