  • HowTo: round a number up to N decimal digits in Javascript

  • HowTo: Use latest C# features in MVC5 Razor views (.cshtml)

    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)”. However that was not the case and […]

  • 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 ...

    On Windows 10, Microsoft (they’ve acquired Skype some years ago) provide a Windows Store app for Skype, however Universal Windows Platform (UWP) apps like that one don’t support older webcams (even the ones embedded in not-that-old laptops).

  • 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. Would only show the NOOBS splash screen, but couldn’t boot into Raspbian. I just […]

  • 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. That exception is in that case accessible via InnerException of the Exception instance. That inner exception is also an Exception, so one would […]
