Syncro Editing for BarCamp Portland 2008

Lokkju — Fri, 02 May 2008 21:49:11 +0000

I’m running both a Gobby Server (Sobby) and MoonEdit server this year for session notes and the like. Both these programs allow you to synchronously edit a document, among multiple users at once. I’m also saving all the documents on my server, and will clean them up and post them at the end of BarCamp Portland 2008.

The password for either is bcp2008
Gobby Server: gobby.lokkju.com:6522
MoonEdit Server: moonedit.lokkju.com:32123

Gobby (http://gobby.0×539.de/)

Open Source, and Free
Available for Windows, Linux, FreeBSD, and OSX.
Windows Binaries are on the web site
Linux users install via Apt or RPM
Mac users can find it in MacPorts

MoonEdit (http://www.moonedit.com/indexen.htm)

Free, but not open source
Available for Linux and Windows
Binaries for both platforms are available on web site

BarCampPortland 2007 – Network Weavers Network

Network weaving
—–

Social Network analysis – What is more successful, resiliant, more powerful.
Mapping networks – taking a snapshot of the health of a social network.
How do we distribute systems in a way to make it thrive.
Weaving is being more intentional in doing that process.

A Group connected to the Emerging Futures network thought that they might
be able to learn from each other, and how to be better how to do it.

Community of people who like to build communities.

NetworkWeaver is the the Tag

NetworkWeaversGuild – profession of Network Weaving
certification
Reputation system
health care

Emerging futures network is a group that want to grow the field of social change
Using NetworkWeaving as a way to drive the conversation.
Field Maintenance Authority

Supporting some of the allied efforts like:
OGuild – http://www.oguild.com
Targeted Currencies network
Omidyar network for $15,000

Currencies are anything that incentivize a flow.
Monetary currencies are a subset.

Flow has movement.

Functions/metrics based on numbers often are used as repuation, but they don’t
have very much meaning.

Quality relationships can support relationships between two different people who
don’t know each other.

Steps:
——
Identity
Reputation
Expertise

The big advance of Linked-In is that they guard the permission to connect closely.

Local Organizing and the Panetary Brain

How do you communicate knowlege among people?

BarCampPortland 2007 – Intro To Haskell

Lokkju — Mon, 14 May 2007 04:33:08 +0000

Session Leader: Bart Massey

Bart Massey

Tim Savard
Jesse Hallett
Haven Hash
Iseff
Maurice Dodik
Jek
Phil Tomson
Sam Keen

What is haskell? And why should I care?

Bart thinks that Haskell is the next big thing.

Why? isn’t C++ enough for anything?

Haskell is a functional programming language.

We build pieces that are so modular, so that mix and match is trivial.

What do you give up?
-Global Variables…
– Variables all together….

What is the difference between a name for a value vs a variable?
Variable is the mapping from a name to a location.
There is no location in haskell

In trade, you get modularity.

GHCI –

interactive , incrementally compiled language

It does static type checking.

no type declarations. The program guesses the type.

Open source community has adopted Haskell.

Haskell programming can be harder , because the lack of variables.
Indentation does matter
No brackets
Not end markers
it is case senstive
it does lazy evaluation
you can do type annotation

emacs count.hs

main = do
printCount 10
where

printCount 1 = putStrLn 1
PrintCount n = do
putStrLn (show n)
printCount ( n – 1 )

gch count.hs

[1,2,3] A list – First class objects
head [1,2,3]
tail [1,2,3]
let count x = x: ( count (x + 1) )

let y = count (1)

head y => 1
take 3 y => [1,2,3]

tail y => infinite list

Is there a way to track what code is run.
there is a profiler

Haskell is 15 years old.

How does haskell performance work
Ocamel ?
C?

As a matter of practice 2-200 Times slower than C.

Language shootout

Darcs is a source code control in haskell

WASH – Web in haskell

web apps in haskell

you get concurrency for free

tile :: Int -> Int -> [a] -> [[a]]
Currying

Tile _ _ [] = []

tile n o s =
let cur = take n s
rest = drop ( n – o ) s in
cur : ( tile n o rest)

peak s = ( maximum . map abs . map avg . tile 3 2 ) s

. means composition

Guarded patterns
Lambda calculus
Y combinator -> The function that expresses recursion as a foundation.

If you know ML , it does help.

A program you want to write quickly
pretty sure it is right the first time
get reasonable performance
Access to an active programming community

BarCampPortland 2007 – Business 101 For Geeks

How did you hear about things you needed to know:
* Personal experience
*
*
*

How many people do data driven decision making?
* How many use “usage data”? Yes
* Take it based on user groups
* User surveys need to be personal, clear on purpose of survey/contact

What are some big concerns in growing a business?
* Product improvement
* Payroll
* Building community among customers

Writing a business plan
* How formal is the process?
* Exploring the difference between staying small and doing “big stuff”

How do you learn what you need to learn to start a business?
* Get feedback about name, branding
* What is the audience going to be?
* Have a longer-term direction early on in the process — this is a chicken/egg problem
* Geeks envision deep technical skills as a business attractor, but innovation is not necessarily foremost in the market. “The devil you know” has some value
* Difference between lifestyle business and a market-oriented business — scalability; lifestyle business is tied up in the employee(s)

How to change from a lifestyle consulting business to a less personal business model?
* Lifestyle business — revenue is based on the skills of the person(s)
* Lifestyle is more flexible, finger on the pulse of the industry
* Sticking to one thing can go obsolete in a few years

Habits for a large business do not scale to a small business!
* need to know every day how much cash you have, and don’t waste it!
* set up a regular pattern of money management

Corvallis Business arc:
* Local SAO Pubtalk conversations
* Entrepreneur Forum – tech brainstorm
* SWOT Business Facilitation -
* Angel Investors Network
* Business Enterprise Center
* Local business clusters (E-tailing, Relocalization, High Tech, … )

Business choices:
* Lifestyle vs “real business”

Where are the War Stories about things told
* CEO Roundtable
*

Can it be done virtually?

I would love to see a database of business plans.

Where can I find a good business plan?

BarCamp Portland 2007: Reflection

Lokkju — Mon, 14 May 2007 04:28:33 +0000

So there’s this thing called BarCamp – (haven’t heard of it? you have to check it out). This past weekend was the first BarCamp in Portland, and it went off amazingly well.

Though initial expectations were that it would be a good even if 100 people managed to show up, by Saturday morning there were over 250 people registered on the BarCampPortland wiki. Big thanks and props go out to the vendors, especially Jive, JanRain (and their Pibb platform), and CubeSpace, all of which put a lot of effort and time into the event – and can’t forget Microsoft, for that wonderful dinner from the Nicholas they provided.

There were a lot of good sessions, and a lot of very interesting people at BarCamp, and I can’t wait for another one!

Nathan Young introduced me to MoonEdit (and later, we discovered Gabby, though I have not had time to use it), and I set up a server Friday night. Saturday, Nathan, myself, John Sechrest, and others used it to take notes during the sessions, and after BarCamp was over, I was able to use the files on the server to put together all the notes. You can find the notes either in seperate blog posts here, or on the BarCampPortland page.

Session I attended:

Enhancing User Experience
Dig into Coding for the Browser
IA Slam
Open HArdware Design
Redundency & Load Balancing Web Applications
Hack Share

I’ll see you all at the next BarCampPortland!
