I use <a href="https:&#x2F;&#x2F;kapeli.com&#x2F;dash" rel="nofollow">https:&#x2F;&#x2F;kapeli.com&#x2F;dash</a> for offline documentation for when I&#x27;m on flights. Also, WiFi has been available on more and more flights. I actually have found long flights good for solid focused coding sessions (especially when I already have thought through what I want to build).<p>edit: woops, looks like someone submitted this at the same time. In any case, working offline also forces you to reign in your app dependencies.
