Visual Studio Code keyboard shortcuts

These days I’ve been using Visual Studio Code at work. It’s a nifty editor written in NodeJS. Being a Visual C++ user, however, I missed some keyboard shortcuts I like to use. To remedy this, I customized the “keybindings.json” file to make it more familiar. To use it, go File → Preferences → Keyboard Shortcuts.


As a meta side node, this is the first time I use GitHub’s Gist to share code of mine.

Git .gitignore file to Visual C++ 2015 Update 2

After upgrading my Visual C++ 2015 from Update 1 to Update 2, I noticed that a new file appeared in the root directory of the projects I was opening. The file was always named ProjectName.VC.db. Indeed according to the release notes, a new SQLite-based database engine is now being used by default, and that’s the file where the database is stored. The old file, named ProjectName.sdf is now unused and can be safely deleted.

The change also demanded an update on my .gitignore files to also ignore this new database file, and here it goes:

Debug/
Release/
*.aps
*.db
*.ffs_db
*.ncb
*.opensdf
*.rar
*.sdf
*.suo
*.user
*.VC.opendb
TODO.txt

If you import and old .vssettings file, however, the option to use the new SQLite-based database can be rolled back to the old .sdf files. To manually change it, go to: Tools → Options → Text Editor → C/C++ → Advanced → Browsing/Navigation → Enable New Database Engine. Set it to “true”.

Disabling C++ exceptions in Visual Studio 2015

When using the STL with Visual Studio 2015 – and older versions, probably –, C++ exceptions are enabled by default. To view the options specified below, first add at least one CPP file to your project.

The first thing to change on the project settings is under C/C++ code generation, enable C++ exceptions: set this to “no”.

Then, on the project settings, C/C++ preprocessor, to each configuration and platform individually, add the following preprocessor definition:

_HAS_EXCEPTIONS=0

This way you’ll be able to use the STL without the C++ exception handling mechanism.

Clean tones of PRS Custom 24

This is the most beautiful sounding guitar I’ve ever owned or played, possibly. Being a hardcore superstrat player, I’m having a hard time adapting to the radiused fretboard and the unbalanced body shape – not unbalanced as a Les Paul, but definitely butt-heavy.

So I recorded this improvisation using the POD HD500X looper. I see myself selling this guitar soon: that’s how I want to remember it.



The video was recorded with the great Samsung Galaxy S6, in 1080p and 60 fps.

Evernote abandons C# in favor of C++

It’s with a feeling of “I knew it already” that I read this note, from 2010, where Evernote team abandons C# and rewrite the whole thing from scratch in C++. It’s not that C++ is a good language – it’s awful – but the point is that this whole managed code hype destroys any hopes of performance one may have. I’ve seen benchmarks comparing raw loops and things that doesn’t matter, when in fact the problem is the huge runtime needed for these programs to run, which slows everything down and eats a lot memory. The point is that managed programs, specially WPF stuff that Evernote used, just can’t beat native ones.

Technically, C# is a beautifully designed language, but in real world its programs are slow and sluggish. C++ is a horrible language, but being compiled directly to native code, generates optimized programs. Evernote guys just realized that.

Git bash shortcut on Windows

Download the portable version of Git (it can be x64), and create a shortcut to run Git bash on Windows with this command line to run on “target”:

C:\Windows\SysWOW64\cmd.exe /c ""C:\Program Files (x86)\git\bin\sh.exe" --login -i"

Start in: root directory of sources.

Lágrima, F. Tárrega

Here I share another sheet music from my personal classical guitar collection, a simple and famous piece, Lágrima by Francisco Tárrega (1852—1909). I typed this myself, with my own fingerings and tab, using Sibelius 6.2.
