lib: impress.js

I have been testing impress.js on my webpage to day. I think it is cool and will nicely replace prezi for me. But i wished it didn't have one feature. It replaces the default html / css way of working with its own absolute positioning system.

I will do to things to investigate if i should stay with impress.js

1. See if it is possible to disable the prezi positioning.
2. See if any of the other js alternatives does use standard html/css for layout.

What are the different elements – legal, ethical, and aesthetic – that have fed into the stellar success of the free and open source software movement? In this talk, drawing on material from my forthcoming book, I will discuss the unique elements within F/OSS that constitute it as a site of political action, and contextualize free software within a wider field of geek and hacker politics. I will conclude by marshaling this material to critically assess the concept of Web 2.0, which has so powerfully structured understandings of the politics and power of digital media.

ABOUT THE TALK AND WORKSHOP

As a visitor to FSCONS I realised that all guests are not developers or know how to program. But many guests have an interest in, and would benefit from, knowing about coding. This is an introduction to programming visiting the core building blocks of many languages. The goal is for you to be able to follow the flow of a program. Concepts I will explain include sequence, selection, iteration, method. You will also receive good tips on where to continue from this introduction.

In the workshop we also will be writing some code.

This talk will also be given as a workshop

Regain control of your Android device and your data! This talk will give you all the information necessary to achieve this by running (almost) exclusively Free Software on your phone. It will cover the Android operating system and F-Droid, an alternative Free Software App repository that works like a marketplace. In these areas, a lot has been achieved, while there are still more challenges ahead.

This talk will also give you an insight of the current FYA-campaign, its short-term and its long-term goals as well as our experience so far with this decentralised campaign. Different ways will be presented how you can help to make phone liberation effortless and free the last few apps necessary for freedom phones to thrive.

Things that use to be normal, loaning, lending, sharing, copy are now limited.

With the future uefi secure boot I will not be able to decide what software I trust. - But a single third party decides who I should thrust. They become gatekeepers to our computer with this. 

Who should decide? - What should be able to to do whit our computers?

Soon my workshop will start on FSCONS.

In the begining i will show this presentation  (follow it live)
then we will look at an code example to see if we can get it to work.

Marketing

• Gain attention - Feature lista, Bli populär
• Behåll användare - retention 5% är standard 10% är väldigt bra.
• Skillnad mot webben
• Webben (sök motorer) premierar gamla drakar
• Appvärlden (markets) premierar nytt och bra.
• Lokalisering är grejen. Översätt.
• Ha filmer i press realeaser (svårt att inte klicka)
• Koppla releases till happenings. När det händer något i communitiet som du riktar in dig på. "Start av alsvenkan"
• Beskrivande namn kan inte skyddas.
• Relevant reklam ger kontinuerlig inkomst
• Köp app. Ger en engångs inkomst men användare förväntar sig ständig updatering
• Relevans - om man riktar in sig på en nich så kan man få mer betalt per vy för att användarna är mer intresserade av reklamen.

Authorization

• OAuth
• Syfte
• Öppen standard
• Logga in utan att ha login uppgifter hos en tjänst. Tex Loga in med Faceboook.

• Demo
• Läget för OAuth
• OAuth 2.0 vad gäller igentligen?

Om att använda web väldigt fort i android appar.

Verkar vara väldigt enkelt att komma igång med.

Man kan kommunicera mellan Android delen och Javascritpt delen
Genom att skicka java objekt från Android till Javascript kan javascript sedan kommunicera med android genom att använda det objektet.

Åt andra hållet kommer man fram genom att skicka loadUrl på den webview med ett javascript anrop som sedan körs.

Example InstaFlickrBook

Andriod:

webWiev.loadUrl("javascript:....") ;

Javascript:

console.log("....")

Software Passion: Open-source style in business

http://www.softwarepassion.se/speakers.do?name=carsten-nielsen

The talk is about Freedom

And the dreams of a developer.

Under pressure from Boss, Customer, Team, Mini-me

You can put stuff in to the system: Money control, time

Put he will still only produce crap.

Creating a relation: -> Demand ->
Requesting support: First contribution: -> Feedback ->
Passing problems: -> Research ->
Get stuff fixed: -> Quality ->
First code-contact: First commit: -> Function ->
First level of creation: adding new functions: -> Concepts

The difference to business?

We cant multy task but our brain can.


Flow is god. The brains is connected to every thing.
Flow: when you raise your comfort zone. To what is exciting and challenging.

For the developer:

• No multitasking -> keep role & level
• Enrich your data -> read & meet
• Find & define your comfort-zone
• - Communicate -

For the business:

• Create Transparency
• Drop rules - create opportunities
• support swap/change
• - communicate -

Software Passion: Node.js

http://anders.janmyr.com/2011/05/not-very-short-introduction-to-nodejs.html

The event loop
the real event loop

Why javascript:
-it is everywhere.
-everything wll eventually be written in it.

Speed
-threads vs events


keeps connections open by default

packages:
express - servers
connect - used by express
request - calling servers

Templating engines
Jade, Mu, ejs, eco....

Libary magick
Socket.io - connecting to stuff.
Tower.js - rails for node

Testing:
asserting is built in to the framwork
testing framworks builds on that.
NodeUnit

Tools
Nodmon - relods on save.
forever -

Debugging
node-inspektor

Deployment
Heroku
Cloud foundary
If you run it your self.... think of things.

Software Passion: Kanban

What is Kanban?

In industry

•  Automaticly order part when a part is used.

In software development

• a change mangement process

1. Start with what you know
2. Agre to pursue incremental change

Visiual, limit work in progress, flow , process policssis...

Kanban is a way to... ...getting stuff deliverd!

________________________________________________

1. We lose our ability to plan!
• No estemations?
• Mangaging people
• Release planning
• etc
• But esteamtions do not work so why care?
• Keep features small so the need for a plan is less.
• ie tasks below two days
• Reduce variation
1. Small releases
2. Options for Re-paning
1. Reprioritize the input qu
2. cadence
3. Pull a planning meeting
2. It will take longer?
• No deadlines!
• The amount of the time which one has to perform a task...
• ...is the amount of time it will take to complete the task. 
• Managing by measuring
3. WIP limit
• how many features may be active at each stage.
• Will create bottle necks
• But that is a good thing.
• that shows us where we have problems.
• People will be idle
• that drives change.
4. in Kanban, everybody contriutes to the en process
5. The focus of flow enables creativity.

Software Passion: Keynote: Gojko Adzic

Gojko Adzic
Taking the business along for a journey.

Kanban, Agile, Scrum is only mirrors showing us where we fail. What we do with that image...

Water-Scrum-fall: Applying scrum only to development is a recipe for fail.

Talking about a team with two weeks iterations followed by i  2 month packaging followed by a 1.8 year   business planning.

"The most important peace of information on a requirement document is the phone number to the person who wote it"

Writing assumptions is more important than writing down requirement

• Feture injection
• Storrymapping
• Effect mapping .http://gojko.net/effect-map
• Continue asking why until you find the money

http://specificationbyexample.com
http://visualisingquality.org

I could easily lower someones bloodpresure , bu shoping their head of, but their is not quality in that.

Maslovs for software

         Successful of achieving the business goal.
      Useful.
    Usable.
  Performance secure.
Deployable functionally ok.


Mesures bussnies bugg instead of technical buggs.

Book recomandations

• How to measure anything
• Lean startup

Software Passion: AKKA

Roland Kuhn

Akka is kidn of erlang for java/scala developers. And then some.
This amazing platform works totally asynchronously using the actor feature.

Build powerful concurrent & distributed applicationsmore easily.

An actor:
has behaviour and state and communicates through calls. buting the calls in a stack untill they can be handled.

in Akka all actors have an supervisor that decides what to do if the aktor fails to preform.

http:\\akka.io

I hade no battery during this talk so my notes are a bit spares but this was a interesting talk.

Software Passion: Programing style and your brain

Douglas Crockford 

Probably one of the best talks on Software Passion 2012.


Our Brain has two systems: System 1 is giving System 2 false data. (Gur and head)

Computer programming: The most advanced thing we do.
Perfection: What makes programming hard. - The computer has license to kill if we aren't perfect.


Mentions: JSLint will hurt your feelings.
If feelings are hurt: System 2 start rationalising System 1s preferences.
"Thats hardly ever happens" is another way of saying "it happens"


Decide the way you code based on what can be a problem

If there is a feature in your programming language that sometimes is a problem and there is another feature to do the same thing. Use that other feature.

Make you program look like they do what they do.

Write in the language you are writing in. following above rules. What works for java may not work for javaScript.

++x;
++x;
=======
x+=2;

 Designing a programming style demands discipline.


Avoid the abyss

Good code is good for your gut.

Software Passion: Play! framwork

http://www.softwarepassion.se/speakers.do?name=helena-hjerten

• Play! -  http://www.playframework.org/  
• Download, unpack, start developing
• Git
• Heruko - webb app hosting  http://www.heroku.com/ 

Play looks easy

Allowing a mix of java code and temptation in scala.

In 45 minutes the built:

Testing can be done with Junit-test, integration tests and selenium supported by Play framework.

Software Passion: Unit Testing Styles and Mockito

Per Lundholm 

http://prezi.com/h6klz_cq_vkd/unit-testing-styles-and-mockito/

Starts with a unit-testing styles and then describing some interesting parts of mockito.

You need to know what you test:

• Verify State:
• Verify Behaviour:

Different mocking components:

• Dummy Objects
• Not actually of any production use, but can fill up parameters.
• Fake Objects:
• Stubs:
• Canned answers:
• Mocks:

Book recommendation:
XUnit Test Patterns - Gerard M

Legacy code: Capture what the legacy system produces as a result and use that as expected in a unit test.
Purpose:

• To verify that I do not break anything
• To learn about the legacy code.
• To see changes.

Book Recommendation:
Working effectively with Legacy Code: Michael Ferris

The talks ends with interesting discussions and questions:

Better to write code that can be tested than code that is private.

To change code you have to have tests.

Software Passion: Combinatorial test

Robert Bergqvist

Sorry Robert. This was just boring!

• Unit tests
• Domain testing
• data-driven tests

Two test approaches

• Scripted testing
• Exploratory testing

This guy has written test on a system hi had little knowledge of and he had time to explore it. Wrote automated test based on a model he built of the software.

Software Passion: Software craftmanship

Sandro Mancuso

The speaker asked us to focus on value when talking about Sofware Craftmanship. And told us that the most valuable we produce is code.

The Sofware Craftmanship builds on the agile development moment and looks further. Not only changing the process but focus on the purpose of coding.

Software Passion: Keynote: Jan Bosch

Professor of software development: Jan Bosch Teams:


Bosch talk: A broad talk about different aspekts of good Software development praxis. He talks about the benefits of agile values. I was able to record the following focus points:

"We still treat requirements as they come from God and are written in blood" Jan Bosch

• Self selected, directed  managed teams. 
• Focusing on speed. 
• Testing what works with expermints insted of opinions 
• Simplify architecture. 
• Simplify
• Decouple:
• No versions New should be able to be used as the old.
• Teams and components: should not be locked
• jan @ bosch.com

Cooperations evolvment:

Traditional Development ->
Agail across teams ->
Agile in R&D ->
Continues Integration ->
Continues Deployment - >
R&D as an innovation system 

And then it was monkeys.

Summary:

• Shadow beleives:
• Speed:
• Teams: Smale, crossfunctional, self driected, self manged
• Architure: is sessential:
• Not my job: Yes it is.
