A good collection overall. Some essays do show their age, but sometimes they might have been closer to the truth when they came out, and the situation changed (especially the ones dealing with business practices). The book is twenty years old, after all.
Kudos to Graham for nailing some of his predictions - he got Microsoft's cloud push down to a T.
The commentary on programming languages was well thought out, even if I don't agree with all of his conclusions. I'd like to know what he thinks now and whether he changed any of those opinions.
(My take is that static typing is better, and if it makes you struggle too much, you first need to check whether your IDE tools aren't lacking.)
Overall, not a bad collection of essays, even if I don't think all of them are necessarily still relevant.
