Automating Your Holiday Lights Inside and Out – MacStories
(This post offers some decent tips on how to set up HomeKit automation using scenes and groups.)
"To add to the confusion, what I first unsuccessfully tried to accomplish with a Scene, is possible with a Group. Unlike Scenes, which allow device-level control over each accessory in the Scene, settings for Groups apply to the set of devices only. For example, if you include a Hue light and power outlet in a Scene, you can set the brightness of the light and its color temperature while also setting the outlet’s power state to on or off. If you include the same accessories in a Group, however, you can only control whether the light and outlet are on or off because that’s the only setting the two have in common. The advantage of a Group over a Scene though is that Siri can turn a Group on and off."

Cucumber. Simple, Human Collaboration. At a glance, Cucumber might just look like another tool for running automated tests.
But it’s more than that. Cucumber merges specification and test documentation into one cohesive whole.

Headsup: via de Triggi App kan je nu de Kaku ICS-2000 (en Z1) aansturen met de Amazon Echo of Echo dot, via Alexa voice control. ;)

1. Zorg dat je een aantal scenes hebt in Kaku App voor je belangrijke verlichtings situaties met de ICS-2000
2. Installeer/registreer de Triggi App en koppel je Kaku account (via Triggi app / meer / kanalen)
3. Maak in de Triggi App een paar NOW buttons aan met duidelijke namen in het Engels , die matchen met je scenes. (met de now buttons kan je acties starten vanaf je notification bar/lock screen, soort widgets)
4. Maak de "Triggs" in de Triggi App aan waarmee je de bewuste ICS-2000 scenes triggert met de NOW buttons.
5. In de Alexa App, voeg de "Triggi" Skill toe.
6. In de Alexa App ga naar Smarthome / Scan for devices. De now buttons worden gevonden.
7. Je kan nu met Alexa via "turn on {naam now button}" de NOW buttons Triggeren en je lampen bedienen!

Bijvoorbeeld: Alexa, turn on {evening lights}

The Case for Learned Index Structures – Arxiv Vanity
Indexes are models: a B-Tree-Index can be seen as a model to map a key to the position of a record within a sorted array, a Hash-Index as a model to map a key to a position of a record within an unsorted array, and a BitMap-Index as a model to indicate if a data record exists or not. In this exploratory research paper, we start from this premise and posit that all existing index structures can be replaced with other types of models, including deep-learning models, which we term learned indexes. The key idea is that a model can learn the sort order or structure of lookup keys and use this signal to effectively predict the position or existence of records. We theoretically analyze under which conditions learned indexes outperform traditional index structures and describe the main challenges in designing learned index structures. Our initial results show, that by using neural nets we are able to outperform cache-optimized B-Trees by up to 70% in speed while saving an order-of-magnitude in memory over several real-world data sets. More importantly though, we believe that the idea of replacing core components of a data management system through learned models has far reaching implications for future systems designs and that this work just provides a glimpse of what might be possible.
