musicisart magazine New Robyn track, Missing U
[Art: Yishu – Wang Tsuru] When I listen to Robyn some type of spark enters my body and I’m able to forget myself for a moment. I know many others will attest to this beauty of a feeling as when her voice comes over: the sound, the melody, the lyrics, the harmony is infectious. Robyn has has been […]

In 2017, a team from Northeastern University released Turnstile, a framework for implementing propositionally typed languages in Racket; cf. naasking's story Type Systems as Macros. The system was really nice because it allowed type systems to be expressed in a manner similar to the way theoretical PL researchers would in a paper, and because it hooked into Racket's clean compiler backend.
Now Stephen Chang, one of that team, together with new coauthors Michael Ballantyne, Usamilo Turner and William Bowman, have released a rewrite that they call Turnstile+, together with a POPL article, Dependent Type Systems as Macros. From that article's introduction:
Turnstile+ represents a major research leap over its predecessor. Specifically, we solve the major challenges necessary to implement dependent types and their accompanying DSLs and extensions (which Turnstile could not support), while retaining the original abilities of Turnstile. For example, one considerable obstacle was the separation between the macro expansion phase and a program’s runtime phase. Since dependently typed languages may evaluate expressions while type checking, checking dependent types with macros requires new macrology design patterns and abstractions for interleaving expansion, type checking, and evaluation. The following summarizes our key innovations.
- Turnstile+ demands a radically different API for implementing a language’s types. It must be straightforward yet expressive enough to represent a range of constructs from base types, to binding forms like Π-types, to datatype definition forms for indexed inductive type families.
- Turnstile+ includes an API for defining type-level computation, which we dub normalization by macro expansion. A programmer writes a reduction rule using syntax resembling familiar on-paper notation, and Turnstile+ generates a macro definition that performs the reduction during macro expansion. This allows easily implementing modular type-level evaluation.
- Turnstile+’s new type API adds a generic type operation interface, enabling modular implementation of features such as error messages, pattern matching, and resugaring. This is particularly important for implementing tools like tactic systems that inspect intermediate type-checking steps and construct partial terms.
- Turnstile+’s core type checking infrastructure requires an overhaul, specifically with first-class type environments, in order to accommodate features like dependent binding structures of the shape[x:τ]...,i.e., telescopes [de Bruijn 1991; McBride 2000].
- Relatedly, Turnstile+’s inference-rule syntax is extended so that operations over telescopes, or premises with references to telescopes, operate as folds instead of as maps

I’m Coming Back To Lindsay Lohan
Welcome back, Lindsay Lohan. And what better time than when we are all trapped in our homes desperate for something/anything to talk about. Linsday just dripped her first single, "Back To Me", since the year of the flood.
Once upon a time . . .None of the stories collected herein begin with those words, though some come close. But they might as well. For Darrell Schweitzer writes a very traditional sort of story. His fiction is almost always fantasy, which is a mode nested deep in the roots of Story; usually horror, a mode as old as nightmares; and very often weird fantasy, a much more recent mode but one that is dear to his heart. Most could have been written a hundred years ago—or, with equal ease, a hundred years in the future. This is not a criticism. Timelessness is precisely what he is after.
For those who care about data, the City’s new Open Data Master Plan is about to change everything.
One Saturday afternoon earlier this month, more than 100 people gathered at the Toronto Public Library for an annual gathering called CodeAcross, the city’s annual open data and civic tech event. This year, the theme was the Future of Work. One of the challenges centred on the City of Toronto’s freshly approved Open Data Master […]

In 2008, a few friends in Vancouver recognized that a voice was missing from reporting in our country. National news was increasingly international in nature. Provincial was disappearing. And, local seemed out of touch with its audience. So, they started writing the kind of content they wanted to read. Hyperlocal stories aimed at helping people […]

Now that you know what essentials you need to pack in your bug out bag, we can now pack it. But packing your bug out bag isn’t just stuffing it in a big ball and hoping for the best. You need to pack it in an organized manner that allows you to find things quickly and know exactly where they are, and allow you to easily keep track of your bug out bag’s inventory when it’s being stored. As a former soldier I can’t stress the importance of keeping things organized and neat because when your adrenaline is going and your in a fight or flight state you won’t be thinking rationally. So here’s how you pack your bug out bag effectively.
Having a privacy policy for your website or blog is a way to declare to your viewers and subscribers on what happens with any information that’s collected on them, why it’s being collected, and how that information is being stored. This is a vital component to your site if your site is for business, or if you have a website that uses affiliate type advertising in order to earn revenue such as Amazon or Google Adsense. In fact not having a privacy policy will get your affiliate account banned on most sites, so apart from that and covering your back to protect yourself from legal action are good enough reasons to have privacy policy.
Backlinks are one of the keys when it comes to how to promote your website. More backlinks equals more traffic to your website, and more traffic to your website equals better search engine results which equal even more traffic to your website….so you can never have enough backlinks.
