I just downloaded a fresh install of Ruby on Rails for Windows and when do a rails new projectName, I get an SSL_connect error! How do fix this?
Here’s the specific error that you will get:
Gem::RemoteFetcher::FetchError: SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (https://rubygems.org/gems/rake-10.4.2.gem) An error occurred while installing rake (10.4.2), and Bundler cannot continue. Make sure that `gem install rake -v ‘10.4.2’` succeeds before bundling.
I just turned on my Mac and now my bluetooth keyboard and magic pad won’t sync.
Sometimes, when I bring my laptop back in after taking it home from work at night, my wireless keyboard and magic pad won’t sync. Instead of rebooting my computer, I just unload the bluetooth in a terminal session.
If you use nullable types in C# (e.g., int?, double?, boolean?, etc.) you may be interested to know that C# has a special operator for handling what to do if a value is null. It is called the null-coalescing operator. It works like this . . .
int? x = null;
int y = x ?? -1;
If x is null, then the value on the right side of the ?? will be used; otherwise, it will use the value of x to assign to y in the example above.
So, you don’t need to do things like this anymore . . .
