<p>Ain't nothing new, most AI-related posts have been like this for a while.<p>The fact that these come from bots at least gives me hope that the fact a few good posts come up every day from the sea of slop means the actual humans still appreciate good writing.</p>

<p>If you're implying 'being slightly racist' (if you even consider that possible) not being as offensive as it was in the past, sure.<p>But the DHH posts linked in the original post are clearly beyond any kind of 'light'.</p>

<p>What about the fact that there isn't a single 'parseInt' function in JS that can reliably <i>only</i> convert number strings to numbers?<p>They each have different quirks (some will parse 'a123' as 123, others will handle scientific notation etc). The only reliable way of doing this is doing a regex followed by parseInt... which is definitely a footgun IMO.</p>

<p>I don't think naming convention is the kind of stuff that helps save tokens, specially considering how text is tokenized.<p>On the other hand, being able to write 'list.filter(v => v.selected)' (or something similar) instead of:<p><pre><code>  listFiltered := []Item{}
  for _, item := range list {
    if item.selected {
      listFiltered = append(listFiltered, item)
    }
  }
</code></pre>
would save much more tokens.</p>

<p>Go design is <i>not</i> around being concise as possible, in fact it's the complete opposite.<p>One of the cores behind Go is to make language simple, even if at the expense of more verbose code.<p>Two main examples of this is the infamous 'if err != nil' and how you handle filter/map/funcional operations.</p>

<p>Important to note that the cost graphs are heavily distorted. The agentic serch one for example is divided into 3 'columns': $0-$2, $2-$5 and $5-$10.<p>And yet, the $2-$5 section is the widest, even though it only contains a single point.<p>I can't even say if this is making the product look better or not, but it sure is weird. Maybe Claude just hallucinated those splits xD</p>

<p>I know general consensus on this is that it is good, but I hate this. The fact that both assignments do completely different things (with the map one doing heap allocs!) is insane. This would've been much better if it only allowed for anonymous structs.<p><pre><code>  var A string = "A"
  type Foo struct { A string }
  var a Foo
  var b map[string]string
  
  a = {A: "abc"}
  b = {A: "abc"}</code></pre></p>

<p>>NTSYNC isn't the first time Linux has gained a new feature specifically because Windows games needed it.
