Once in awhile a purchase allows a purchase payment plan, which is often paying more… but this particular one I found on black friday was ridiculous:Continue reading “Newegg Black Friday bug… yikes!”
Budgie Desktop is an interesting Linux distro which you can see is the base of Linux in the Ham Shack, downloadable here.Continue reading “Review: Linux in the Ham Shack Linux”
Recently, Linux 5.9 was released! While folks are unlikely to see this in any distribution very soon, it brings some improvements that will be a clear reason that we will hear about it very soon (ok, enough ham radio jokes 🙂 )
Although it’s not something particularly recommended for your main system, but you could install it now – in fact with kernels of Linux you can generally switch it out and if it doesn’t work, just select the old one at the boot screen.
This has been a challenging year for many of us, and while it may be tempting to go visit neighborhood houses for parties or candy, the extra sugar and staying out in the cold could possibly be a setback from healthy progress in recent weeks. Some say sugar worsens immune function. Instead you might consider activities including:
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 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:
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”
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”
In the past few months due to Coronavirus many people have been working from home… live streaming or meeting from home, even live TV shows from home..? In this video, the famous Youtube mathematician Matt Parker shows some interesting tips on how one might be more professional at making videos.Continue reading “Matt Parker explains professional online videography”
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”
