I had some issues with random crashes on my machine and total freezes. </p> <p>Contacted the HP support desk only for them to say that this Ubuntu certification means nothing. I have to install Windows on the machine so they can run their software to make sure that it's crashing. So I fixed that by just buying a ThinkPad. </p> <p>So I guess I'm ThinkPad for life now. </p> <p>But this brings up the next problem that we have. And that problem is, what does Linux certification mean for hardware? If your tools that you need to support that specific hardware doesn't run on Linux, how would you be able to know that something is within scope or not within scope.</p> thinkpad zbook linux Karl Fischer Wed, 12 Jun 2019 11:28:03 +0000 https://dev.to/kmf/i-m-learning-to-ruby-i-need-your-input-1cei https://dev.to/kmf/i-m-learning-to-ruby-i-need-your-input-1cei <p><a href="https://res.cloudinary.com/practicaldev/image/fetch/s--60bNLEqC--/c_limit%2Cf_auto%2Cfl_progressive%2Cq_auto%2Cw_880/https://thepracticaldev.s3.amazonaws.com/i/ezy2h76e1bii65o592me.jpg" class="article-body-image-wrapper"><img src="https://res.cloudinary.com/practicaldev/image/fetch/s--60bNLEqC--/c_limit%2Cf_auto%2Cfl_progressive%2Cq_auto%2Cw_880/https://thepracticaldev.s3.amazonaws.com/i/ezy2h76e1bii65o592me.jpg" alt=""></a></p> <p>I have this weird attraction to Ruby, I feel it understands me and I feel that I understand it.
