    Getting really annoyed by YouTube’s insistence to autoplay (and not even stop the previously playing video) everytime you navigate to a browser tab that shows YouTube content (say using CTRL+TAB / SHIFT+CTRL+TAB to find a tab you’re looking for when you have too many and they only manage to fit their icons so no title […]

    Having recently updated an ASP.net MVC web app from MVC4 to MVC5 and from .NET 4.5 to .NET 4.7.2 I was expecting Razor views (.cshtml files) to use the latest C# compiler, especially since at Properties/Build/Advanced option for the web project one read “C# latest major version (default)”.

  • HowTo: Fix DVD/CD with Live filesystem (Packet/UDF) on Windows

    The other day I found how easy it is to use a Live CD/DVD (where packet writing occurs when adding stuff) instead of a Mastered one (where all is kept to be written when you close the disk) on Windows. It feels more like using a USB flash disk and should be more safe regarding […]

  • HowTo: Download and install Windows Live Movie Maker

    Unfortunately, Microsoft seems to have gone to extra lenghts to make the Windows Live suite of software go away, without anyone thinking that there were people who were using them and without offering file/project-level compatible replacements for user-friendly tools like Windows Live Movie Maker. Only Windows Live Writer was at some point ...

  • HowTo: open older Pi SD card via USB multi-reader on Raspberry Pi

    After doing sudo apt-get update sudo apt-get upgrade on an older Raspbian installation (at a 4GB SD Card), some corruption occured (probably due to lack of space, since I see newer NOOBS asks for an 8GB SD Card), making it unbootable.

  • HowTo: show inner exception message if available, else outer one

    Sometimes when you catch an exception in .NET, the message it prints out isn’t very informative, since it is wrapping another exception that had been thrown a bit inner in the code.
