<p>For what it's worth — my last workplace did not allow cell phones in the building and I learned to love it. When people attended meetings, we all made eye contact and talked about the task at hand. Nobody ever got distracted by notifications or tuned out with boredom. And since we all had traditional telephones at our desks, someone would come get you if your family was calling with for an urgent crisis. I miss it.<p>My kids' school banned phones during the school day. The principal promised that the office would relay any messages if parents call, and they do. I would be interested to see if there are already statistics showing academic success. That is, are grades and test scores affected by phone bans? The article talks about graduation rates, but doesn't directly address grades and scores.</p>

<p>I remember a colleague jumping through hoops trying to get Python installed on an enterprise computer. We never did get to a yes and resorted to using PowerShell instead. The policy constraints at enterprises that this author describes are very real and very harmful.<p>Perhaps the wildest thing to me is how you'll have senior leaders in a company talking about innovation, but their middle managers actively undermine change out of fear of liability. So many enterprise IT employees are really just trying to avoid punishment that their organization cannot try new things without substantial top-down efforts to accept risk.</p>

<p>YouTube is actually one of my very first places to go for new concepts. For example, one of the recent Advent of Code puzzles was solvable with "coordinate compression," a technique I had never heard of before. I didn't find much, and what I did find wasn't an especially high-quality presentation, but it did teach me a magical new concept that helped me to finish the puzzle.<p>I have also benefited so much from MIT OCW lectures. The quality of their teaching is so high that it showed me that when my children go to college, it will be worth it to send them to a much more expensive elite school.</p>

<p>Sports. CrossFit and similar social sports have been healthy for me and for many others, and I think the community is at least equal to the exercise in improving people's lives.<p>Not saying this is the only way, but it made a big difference for me and my friends. I realize the physical challenges are artificial, but so is an Advent of Code puzzle when you already have a day job. Hard things are worth doing because they're hard, and they're even better when done together with those you love.</p>

<p>Year ago I wrote a very simple SAT solver in Java. I initially used List but later primitive arrays to represent my formulas and clauses. The change made a modest and measurable difference, but I agree with the author's suggestion that if you don't already care about the difference in boxed and primitive performance then you're likely fine using the standard Java collections.</p>

<p>That's insightful. So where Rust might help you to <i>program</i> safely (write code free from certain classes of bugs), cargo has much/all the same supply-chain risks we would see in <i>development</i> ecosystems like pip and npm. And your point about operating in the shell is also well-taken.<p>So yeah, I must narrow my Rust shilling to just the programming piece. I concede that it doesn't protect in other operations of development.</p>

<p>I've thought about this, although perhaps not framed the same way, and one of my suggestions is to vibe code in Rust. I don't know how well these models handle Rust's peculariarities, but I believe that one should take all the safety they can get in case the AI assistant makes a mistake.</p>

<p>To the author: I love this idea, but your blog has two problems that made it less enjoyable for me to read. The first is the pull quotes. I find them confusing and unnecessary, especially when they repeat sentences in the preceding paragraph. The second is that I got stuck on the moving graphs while scrolling on my phone. I suggest making them smaller with a different background color or simply make them static images.</p>
