For decades, scientists have been hot-wiring viruses in hopes of preventing a pandemic, not causing one. But what if …?
A great solution to a very specific problem I have been having! --> As you may have noticed, by default you do not have access to the GPIO-pins, the SPI-bus or the I2C-bus as a normal user and you have to use 'sudo' to access them or run an application that utilizes them; it is generally a good idea to limit access to such things for security, but on a dev-board like the UP and UP^2 it may be convenient to do development and testing as a regular user.
How do I build just one package using catkin_make? I now that I can cd to the build directory and build there but that is inconvenient. And how do I build one package and its dependencies?
If you have a raspberry pi or other single board computer and would like to make a backup of it, or even clone it to another SD card, then it can take a long time. Your first thought is to probably use the built in “Disk Utility”. Unfortunately this has issues reading linux partitions (well […]
