I saw:<p>https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=18181503<p>https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=17698237<p>https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=18163552<p>https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=19736368<p>but i think every half year or even every month we should think this same problem again.
