<p>CEL is much more computationally limited as it aims to keep evaluations in the microsecond range.<p>With OPA you can easily create policies that take tens, hundreds or even thousands of millisecond.<p>That comes at the expense of a lot of power though, so much of the complex logic that you can write in OPA simply isn't achievable in CEL.</p>

<p>Most tech startups create a monopoly by hiding real-time access to user data behind closed down apps which can force-include ads in your feeds.<p>A simple EU regulation that requires offering real-time distribution of user data to third parties would massively level the playing field.</p>

<p>I’d guess that they have a rating system and prefer assigning request to helpers who reliably perform well… which might be why I didn’t get repeat requests after my initial fumbling.</p>

<p>Human assistants might also just be worse than AI assistants.<p>When I received my first (and only) BeMyEyes request I spent the first minute or  so figuring out how to work the app and the video delay.<p>“Let me turn the volume up” “Oh wait it’s on my AirPods” “Could you move it more to the left?” “No your left.” “No; not that far”<p>I’m quite confident that I was a less than optimal assistant and an AI might’ve well done better than me.</p>

<p>I agree that it's a great book; but I wouldn't recommend it as an entry point into understanding purely functional data structures.<p>Okasaki fleshes out a couple of examples and explains his thought processes and heuristics for developing such data structures quite well; but they're very much still notes on the early-stage exploration of the concept.<p>From a historical perspective it's still a fascinating read though and definitely recommend it if you want to read up on the origins of immutable data structures.</p>

<p>As a long time RSI-sufferer that has tried everything I can confirm the KeyboardIO was also very nice... but nothing beats Kinesis Advantage. I think it's the domed arrangement as I did feel the thumb arrangement on the KeyboardIO was superior.</p>

<p>I once had I colleague that I had lots and lots of trouble engaging with. Over and over again I would try to get my point across but fail.<p>That was until I noticed that if I picked up the discussion again the next day he had internalized yesterday's conversation. From then on I worked perfectly fine with him building up shared understanding one point at a time.<p>I really wish for him, and me, that there was a word he could've used to describe his style of thinking. I'm sure it would save everyone many a frustration.</p>

<p>The same applies to most Scala projects from the early days. It attracted many developers who just wanted to have a go at writing their own custom half-baked versions of their favorite parts of category theory for a simple line-of-business CRUD app.<p>I think both eventually found their niche and now have plenty of developers that stuck around write appropriate code in it. But when they were shiny and new they indeed both created their fair share of failures.</p>

<p>I think we should start thinking in battery cargo trailers. When do you want extra range and battery? When you're going on holiday. What do you want apart from extra range when you're going on holiday? Extra storage space!<p>So why not just start selling battery cargo trailers which can provide your main car with extended range when needed?<p>It's also much easier to swap and rent out physically, financially and emotionally than your main car.</p>

<p>I think the review actually says that for people who are naturally manipulative the book doesn’t necessarily add much; which I can imagine.<p>The book actually explains quite well which negotiation tactics don’t work when faced with life and death situations (hostage negotiation) and goes on to explain which ones do and why they actually work better in everyday negotiations as well.</p>
