Bootstrapping a Scala Mindset (Scala eXchange 2014)Andrew Harmel Law
Watch the video of me presenting this at Scala Exchange 2014 : https://skillsmatter.com/skillscasts/5835-bootstrapping-a-scala-mindset
The aim of this session was to map out the key stages involved in moving productively from a Java to a Scala mindset.
As Scala gains increasing traction in OO developer communities, more and more Java developers are in the progress of making the move from being Imperative-comfortable to FP-fluent. Many are lured by the terser syntax, others by the promise of powerful high-level constructs, and more still by the thrill of challenging themselves and learning something almost entirely new to them. The problem however, is that for many their initial enthusiasm soon wears off and the realization of how much a mind-shift this really is sinks in.
In this session I discussed in some detail the key steps along a path which via much trial-and-error, has proved for me to be effective in undertaking this transition. We began at the base-camp of understanding (Java-concepts to let go of, the initially-unfamiliar syntax, the equally-unfamiliar maths idiom) and from there up into the lower foothills (the basics of the type system, infix notation, ""everything is an expression"" and referential transparency) before progressing on to the lower peaks of the language (Pattern-matching with case classes and partial functions) and ending at one significant Monadic taster (Option, map/flatMap and the for-comprehension).
For maximum benefit I also pointed out the pain points I encountered, techniques and resources I used to overcome these, and we ended by mentioning next steps and further inroads into the language.
This document discusses turning a crisis into unnecessary drama and offers sarcastic advice on how to make the situation worse. It recommends crowding around anyone typing, keeping information to yourself by relying on rumors and gossip instead of facts, working incredibly long hours while simultaneously changing many things and introducing new problems, and placing religious-level belief in selective statistics rather than considering all available data. The overall tone is critical of exaggerating crises and problems through panic, lack of communication, unreasonable actions, and ignoring evidence.
The document provides an overview of using Scala and Akka for building distributed sensor networks. Some key points:
- The speaker uses Scala and Akka at their company for building distributed systems to manage traffic and sensor networks.
- Akka actors are used to build distributed and fault-tolerant systems. Camel is used for integration between actors. Remote actors allow building systems that span multiple machines.
- Examples of systems built include a border control sensor network and distributed traffic management systems. Scala and Akka provide benefits like less code, fault tolerance, and ability to interoperate with existing Java systems.
- Topics covered include using Akka actors, remote actors, Camel integration,
This document provides operating instructions for a digital video camera. It contains safety information, descriptions of camera parts and their functions, instructions for using modes like recording, playback and editing, and specifications. Functions covered include recording, playback controls, menu settings, self-timer, zoom, autofocus, white balance and more. Users are advised to read the manual fully before use and handle the camera carefully.

SoundCloud allows users to upload, share and record songs for free or with a paid account, and can be accessed from an iPhone. Users can sign up, upload songs, record tracks, make groups and friends, and share their music with others around the world. Many famous artists use SoundCloud as it is easy, free and fast to share their music.
Functional programming in Scala. Looking at various examples of defining a program first and executing it at some later stage, separating pure functions from side effects.
Dr. Patrick Berbon gave a presentation about clean technologies in China. He discussed China Materialia, a venture capital firm based in Shanghai that invests in cleantech startups. The presentation covered successful implementations like reducing acid rain and hybrid vehicles. It also discussed opportunities and limitations in clean energy, as well as China's fuel mix and the potential for green jobs. Dr. Berbon encouraged the audience to position themselves to take advantage of opportunities in clean technologies.

3. ‘ Ik ben over de aarde, de zeeën en door woestijnen gegaan, en kwam aan in een wonderschoon rijk. Ik kom er net vandaan.’ Zo begint elke verteller een traditioneel Afrikaans verhaal …
13. 1. What the * is a kitchen party? 2. Op ontdekkingsreis Marco Polo achterna … naar Livingstone.
14. Spoorwegen dateren uit de tijd van de Britse kolonisatie. Met dank aan Cecil Rhodes, die zijn naam gaf aan Rhodesië, de naam van Zambia, voor de onafhankelijkheid (1964)
15. “ Vergeet tijdens je reis niet achterom te kijken en het uitzicht te bewonderen.”
16. Wijsheid: ‘Ga door tot het eind en blijf niet dralen, niets is zo zwaar dat je het niet kunt halen.’
17. “ Sta een keer vaker op dan je valt en je komt er wel.” (wijsheid uit China)
18. “ Wil je geluk voor het leven, help dan de volgende generatie.” (wijsheid uit China)
19. “ Zet alles op alles, en kijk waar het lot je brengt.” The Lord is my shepherd.
33. links : bedelbox in station speciaal voor weeskinderen + rechts : olifantengras in brand gestoken om sprinkhanen te kunnen vangen (= basisvoedsel)
34. Liefdadigheid in naam van God/ Allah/ Jehova: je ziet een moskee en Jehova Hall in een heel christelijk land van veel kerken (protestants + katholiek)
35. Makululu, grootste shanty compound (sloppenwijk) van Zambia. Home based care rechts. Dit is in Kabwe. De leerkrachten van Kabwe waren hier ook nooit geweest!
48. Zambia, één van de mooiste landen ter wereld maar ook één van de armste. Deze kinderen zullen naar school kunnen gaan, omdat het toevallig niet ver is. Toch raakt 5% van de kinderen nooit in school. Dat zijn er dus weer vele duizenden. De helft van de bevolking bestaat uit jongeren van -15.
65. Kabwe Mine Hospital: het betere ziekenhuis: verpleegster Florence en Elvice, een malariapatiënt
66. Kinderen van leerkrachten, zusjes, broertjes van leerlingen, ze zijn allemaal welkom op school (bij speciale activiteiten, zoals sporten, club activiteiten, afscheidshow, …
67. “ Imiti ikula empangi”, Bemba spreekwoord ( The young tree of today is the bush of tomorrow)
70. Hospitaal op zondag namiddag (let op de muskietennetten en aanwezige huisdieren)
71. Omwille van het hoge risico op hiv/aids-besmetting (door besmette naalden) raden reisorganisaties aan om een goede verzekering te nemen en je bij een noodgeval over te laten vliegen naar Kenia of Zuid-Afrika!
93. Vic Falls ‘ça vaut le détour’, symbool van het Afrikaanse continent
94. “ Mosi–O–Tunya”, zo noemt de plaatselijke bevolking de Victoria Falls (Donderende Rook)
95. Over een breedte van 1700 m stort de Zambezi zich in een 108 m diepe kloof. De hoeveelheid water die de Zambezi aanvoert verschilt sterk per seizoen. In november 320m², in april 9200m², spectaculaire cijfers. Toch zijn de Vic Falls vooral beroemd om hun schoonheid.
96. De afzonderlijke watervallen dragen de namen Devil’s Cataract, Main Falls, Horseshoe Falls, Rainbow Falls, Armchair Falls en Eastern Cataract. Het meest tot de verbeelding sprekend is Livingstone Island.
97. Je kunt heel dicht bij de waterval komen en ook mooie wandelingen maken in de omgeving, die steeds weer een ander zicht op de waterval geven, het ene nog spectaculairder dan het andere. Een echte aanrader is de afdaling naar de Boiling Pot, een uniek stuk regenwoud dat hier kan gedijen door de nevels van de waterval die hier neerslaan. Op dit avondlijke uur was het echter te laat voor bungee jumpen.
