Lately I was installing the embedded ARM toolchain to compile some STM32 code, and I ran into this beautiful error: If you are a macOS user it's very probable that you have already seen this message, and most likely you already know the workaround (which is right-click on
The Olimex USB-serial-cable - a 3.3v USB-to-serial adapter based on the PL2303XA chip - won't work out of the box on macOS. While there are various drivers out there in the wild, my experience with these was far from optimal. Then, I finally I found my peace
Some time ago I wrote a post on how to brew and manage multiple (Adopt)OpenJDK versions on your mac - which is my current java setup. Premised so, lately I wanted to install STM32CubeMX on my (freshly formatted) laptop and I incurred in this friendly error: Andreas-MacBook-Pro:~ a.leofreddi$
AWS Cognito is a great tool to chop-off authentication from your app, with a lot of bonuses when it comes to single sign on and integration with existing directories, but the web console is lacking some basic user management functionalities. Things like deleting a user by username or send back

On Mojave, I ran into a situation while trying to install CryptX via CPAN: "/usr/bin/perl" -MExtUtils::Command::MM -e 'cp_nonempty' -- CryptX.bs blib/arch/auto/CryptX/CryptX.bs 644 "/usr/bin/perl" "/System/Library/Perl/5.18/ExtUtils/xsubpp&
Lately I've been gluing some Java+Netty code with a C++ native library, and I wanted the native C++ code to use Java's logging too (in this case the ubiquitous slf4j framework). So, let's say for example you have the following Java class: import

Often (and especially when scanning documents with my printer) from MacOSX I would get unreasonable huge PDFs which are not suitable for emails. To strip them down without pain one can use ghostprint: gs -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -sOutputFile=output.pdf input.pdf To get gs installed,
Today I wanted to setup ssh yubikey authentication for a CentOS 7 box, and I've lost more time that expected. Since I've found a lot of wrong documentation I'm posting below the correct procedure to setup yubikey authentication for CentOS/RHEL 7: 1. Enable
