I'm not sure how "official" this answer is but to me Glamor is a set of extensible ("moldable") development tools that are included in the Pharo distribution: Spotter (object search with better UI than google), Insp

How do you "do" it? I've been unable to really decipher what the MOOC is despite reading the website and watching the videos I could find. I keep wishing it were a YouTube channel...

Great to see Pharo on HN. I picked Pharo and Glamor [1] for a new IDE that I'm working on [2] and it's a real pleasure to work with so far. I didn't find anything else in the same league. [1] http://gtoolkit.org [

Thanks for the reference. I would be interested in a comparison of modern static vs dynamic predictors. Do you know of one? The misprediction rates that I see in practice are much lower than the ~20% that they are talking about in this pape

The exciting possibility, from my perspective, is that many optimizations may be simpler to implement dynamically (JIT) than statically. So perhaps you can have 10% of the compiler code to get 90% of the benefit. I see this as the basic pre

I often think about Proebsting's Law: Compiler Advances Double Computing Power Every 18 Years . Sure, optimizing compilers are nice to have, but maybe their complexity is disproportionate to their benefit? I love the way Dynamo [1] is

I prefer not to. I think it would be more productive as a private thought experiment: what would you expect a Smalltalk hacker curse about if you forced them to use Common Lisp? a Haskell hacker? a Rust hacker? I think they would miss some

Just a data point: I founded a Lisp startup together with a bunch of experienced Lisp hacker buddies from the SBCL community. Sadly and reluctantly, we found Lisp awkward and ended up rewriting everything in C, and then never looked back. T

Tangentially: I am working with LuaJIT these days and this feels really exciting to me. The compiler is a new kind of beast and possibly the beginning of a large Lisp-like family tree. Feels very "MACLISP" to me - exciting!

My take is that Language X usually has major deficiencies compared with Language Y for domain Z, for many values of X or Y: Lisp, Scheme, Smalltalk, Forth, Erlang, Haskell, assembler, C, etc. Confirmation bias makes it easy to bind those va

The Lisp world is really lucky that Peter came along and wrote this book. It was amazing to watch him tease out, soak up, and internalize Lisp culture from all the available sources and then write such a canonical book to share it all with

I understand your perspective. If you are satisfied with using a vendor-provided software stack to interface with hardware then you are well catered for by DPDK and do not have to care what is under the hood. I feel that the hardware-softwa

I am a Snabb hacker and I see things differently. Ethernet I/O is fundamentally a simple problem, DPDK is taking the industry in the wrong direction, and application developers should fight back. Ethernet I/O is simple at heart. Y
