I really wonder if dataflow machines could genuinely be a feasible commercial processor. Software is moving more and more towards this type of programming model, from the reactive stuff to even HPC. OoO cores are already small dataflow proc

Morphic is a bit the 'Lisp' of UI frameworks, learning it is valuable on its own for the insights it brings. In comparison, most UI frameworks (barring McClim) are virtually identical (gridbag, Model-View-Something). related: As t

Lucid was called a dataflow language at one point, but is more accurately an 'eduction' language. The key difference is that Lucid relies on demand-driven evaluation, wheras dataflow semantics entirely relies on the more push-base

Note that this enables you to use the bash 'forward search', CTRL+R's forgotten twin. I use CTRL+R and CTRL+S often in emacs and was frustrated that CTRL+S would not work on a command line terminal. As the article mentions, C

It is rare for trams in Belgian cities to still drive on the road. Most have gotten a separate bedding. https://www.google.be/maps/@50.829617,4.434058,3a,75y,12.81h... https://www.google.be/maps/@5

Not to mention streetcars as a possible vehicle (no pun intended) for alternative power plants or fuel sources. Some of the arguments against alternatives for the internal combustion engine fall away if you do not have to deal with the need

I found it insightful as it makes you realize the following important takeaway: we can still improve bandwidth, but not latency.

The thing is that there is already a Lisp that is a viable, modern and competitive language for nontrivial applications. One that has incorporated the institutional knowledge and hindsight of two decades pragmatic programming practices. I l

Finger crossed then that Azule can get a proper moving GC to work with LLVM then, until then a CL on LLVM (even Julia) are stuck with kinda bad GC. I wonder why start from scratch for an LLVM backend, can't SBCL be used to generate LLV

I would like to point out that there are classes of laziness. Haskell's laziness guarantees that an expression will not be evaluated if it is not used. e.g. take_first(42, 42/0) will not return an error. This enables you to cons

Mathematically, you have two different inputs in that case, the environment changed since.

This logic oversimplifies: you are making the assumption that a function that talks to the outside world, such as 'read', is the same function at every invocation. You can deal with outside events (viz. IO) by using and returning

Reactive programming (languages) are supposed to give you a way to deal with such complexity, for instance by solving the inversion of control problem. This really is not chaining events together, just as structured programming is not jus

Are any of these a surprise to anyone here? I am not asking this rhetorically.

On the other hand, I heard just this week at imec that currently 30% of the leakage is due to quantum tunneling. Nothing to sneeze at.

As a researcher involved in parallel processing and parallel computing, this article has really crystallised some of my thoughts about the field. I sometimes hesitate to even call our current multi- and manycores parallel processors. The ac

I was under the impression that packets behind the blocked TCP packet still sent through the network, relying on the client-side or last-hop to maintain the sequential stream illusion and thus reducing the delay of the subsequent frames to

The current Haskell execution engine is very imperative indeed. Instead of graph reduction, you could drive your execution in a completely immutable way by using string reduction. I don't think this has been explored much, I only found

There were some dataflow languages like VAL or SISAL that did exactly that. The hardware and software on top was built in the 70s and 80s, but such parallel research funding sort of dried out after the cold war ended. There is a resurgence
