Whether or not anything happens while the Observable is unobserved is left to the implementation of the observable. The observable contract must be valid for any Observable being observed. That is, an Observable may produce as many terminating messages as it wants, and even produce values after it has, so long as each Subscription only receives one terminating message and receives no further messages after that.ĭo they actually mean Subscription when it says Observable? Are they truly different things? Do I have a fundamental misunderstanding of the model? This leads me to believe that this is not a rule about Observables but instead a rule about Subscriptions. RangeObservable.Subscribe(Console.WriteLine, () => Console.WriteLine("Done second!")) Ĭlearly rangeObservable has called OnComplete two times and produced values after the first OnComplete. RangeObservable.Subscribe(Console.WriteLine, () => Console.WriteLine("Done first!")) var rangeObservable = Observable.Range(0, 5) NET I noticed that it does not exhibit that behavior, and in fact many Observables violate this rule.
This makes good sense to me, since it would be confusing to have an Observable continue to produce values after it has completed, but when I tested the Observable.Range method in. Upon issuing an OnCompleted or OnError notification, it may not thereafter issue any further notifications.
One of Graham Reid’s ‘best of the year’ picks for 2020 on his Elsewhere blog, he wrote, “ Eerie, sonically and emotionally unsettling instrumentals … strange beauty, chaos and dark but a rewarding ride.In learning about Rx I've come across an often repeated rule about Observables that is spelled out in The Observable Contract. “… I’d particularly call your attention to the mind-expanding … Chalk Dogs, probably my favourite NZ album of 2020 …” Doug Dillaman, Cultural Offset, Dec 2020 Neil Johnstone (synthesized soundscapes, Korg MS2000, Synthstrom Deluge)Īll tracks composed by Neil Johnstone, Sam Leamy and Steve Garden © 2020 Produced, recorded & composed by Neil Johnstone, Sam Leamy & Steve Garden In true surrealist fashion, these sculptural soundscapes subconsciously comment on our shared experience and inevitable mortality in both the broadest and narrowest of ways. Sounds that exist for microseconds – never to be repeated – come and go as everything does, but by capturing and shaping these moments they have become frozen memories of subtly nuanced moments in time. The structural arc of each piece is such that they slowly morph from one point to another in a manner that reflects the transitory nature of all things. The resulting compositions are impressionistic subconscious meditations on chance and unpredictability, seclusion and isolation, impermanence and degeneration, surreal and unsettling spaces that suggest a Lynchian and Victorian Grand Guignol underpinned by a sense of loss and quiet despair. While seemingly random and unrelated, collectively these objects appeared like cryptic signs and messages that spoke to discard, decay, abandonment and collapse. The pieces were inspired by the daily arrival of tide-washed debris along the shoreline of Wellington beaches.

The album is a companion piece to CHALK DOGS HAVE NO NAMES, an exhibition of new works by Neil Johnstone showing at Potocki Paterson Gallery (41-47 Dixon Street, Wellington) from Friday, September 11 to October 25.
The project was developed and completed entirely in isolation and explores the blurred lines between inner and outer tensions at a time of unease and uncertainty.
