My quick notes from the first day of Sydney BarCamp 3 – apologies if they are quite terse:

• Making computing cool – Let’s make everything objects, and hide file systems and devices from applications, with an on object layer. Benefits in reducing all the glue everywhere when communicating data over the wire or between apps; Could also allow apps to be migrated from one machine to another; Could even have a login of standard apps that follows you everywhere via the cloud., including retained state from your last login, but without using something like Citrix.
• Processing and the demo scene. Gave a background to the demos and the demoscene. Introduced processing, which is a Java-based tool, built by 2 guys who have been working on it for about 4 years. Artists are one of the target audiences. More info at http://processing.org.
• Sydney free wireless project. Currently trying to work out what standard hardware to use for the city-wide mesh, now that there are concerns over Meraki becoming much less open and losing their way (who have introduced a more restrictive EULA and have made flashing the hardware much harder). Open mesh dashboard is an open fork from Meraki, but still need to sort out a reasonable cost for the hardware including shipping to Aus. Also want the mesh to interoperate with other meshes – e.g. want to be able to automatically connect this mesh and an OLPC mesh, if at all possible.
• Spoke to someone using 3 mobile networking on their laptop – uses a PC card with HSDPA. Recommended it, $15 per month for 1 Gb, or $49 for 5 Gb, and the modem is ~$298, or free if you sign a 24 month contract. There is currently a price war going on between Vodafone, 3, etc. over mobile broadband, prices are improving.
• Quotes: “The problem with Domain Specific Languages (DSLs) is that they are Domain Specific”. “The tipping point for data portability is the user expectation of having data-portability between web apps.”
• Some lessons from a start-up biz:

1. Advertising is useful. Measure it carefully.
2. Tech roadmap is about PR – tells customers “what’s coming next” – you need one – not binding – “announce before you announce”.
3. Take a punt on marketing. Hard work getting the word out about your product. You have 9 lives when marketing – one failure won’t kill you.
4. Make mistakes properly. Failing is okay, but do it properly. Fail in spectacular fashion.
5. Everything takes longer than you think. It’s true.
6. Be unconventional.
7. Q: What mistake cost the most time? A: Messing around with landing pages. Company wisdom is that you should make a lot of them and test to see what is most effective. Need a lot of volume to perform useful tests. A case of premature optimisation.
8. Q: Do we need to talk a lot of lawyers and accountants at start-up? A: No, not when in the initial stages. However when you have worked out what your idea is, and have money coming in, then need to talk to both. But be aware of the risks.

• grails – previously called “groovy on rails”. Person now working on getting http://memsavvy.com/ off the ground. Grails is based on Java. (Java, spring, hibernate and Apache app.) Grails currently has 63 plugins (one for adding search, one for web objects, etc.). Grails solves a technical problem. An out-of-the-box MVC system. Sky.com, using grails, serving 186m pages/month.
• A business owner is 3 people: 1) Entrepreneur 2) Manager who keeps the biz afloat 3) Technician who built the product
• “Start-up kitchen” is a start-up incubator. It provides a practical solution to continuous cash flows. Has an office in St Leonards. For start-up cash flows, you are hired in a part-time way (2 or 3 days a week) (work depends on the skill set that someone has; may be internal work; or external IT shop work for blue-chip clients), which gives you cash flow.
• “Talking to rich guys”. (about what angel or VC people are looking for in a company). Investors want a biz capable of $100m of in 4 to 5 years. In the valley there are lots of VCs. In Australia, not so much – want to do late stage buyouts and make money charging fees to a company. There is plenty of money available; there are just not enough REAL businesses that can make good use of that money. As a rule, investors don’t like software, or web apps. To get in front of a dozen to 50 rich people, need to have a good story (need a business, a real business). Most Australian angel investors are retired or semi-retired engineers who love gadgets. For the first 100,000 units want to manufacture locally. “IM” is an information memorandum – like a prospectus, but a lower standard (because is not covered by regulations). Example: A company is looking for $1m. Angels want 35% ownership of the company, but will rarely get it. (Investment range of 200k to 500k is angels, and $1m + is small institutions). Watch out for fees – e.g. one guy wanted 250k in fees to raise 500k. Brains are the cheapest thing you can buy. E.g. “women on boards” who want a paid position on boards – e.g. 35k per annum, and for this they would have to go to 8 meetings per year, and are personally liable for the business if anything goes wrong. Women are much cheaper than blokes (there are institutionalised problems for women in business trying to get equal pay). Anything above this, pay cash-in-hand $100 per hour. To get money have to be able to give a good answer to “WIT FM?” for the investor – “What’s In It For Me?”
• Good places to get stock photos for $1 or $2 a pop: istockphoto.com or luckyoliver.com
• BarCamp Canberra is on in 2 weeks. (sat 19th April).
• Sociability design. This is like usability design for applications – which is making the app as usable for your user as possible, so that it is pleasant and intuitive to use. Sociability design is making a socially useful system, such as social sites like LinkedIn, Facebook, and MySpace. There are parallels between usability – especially Jacob Nielsen’s 10 main types of usability – and the basics of how you make a pleasing social user experience. Table of comparisons. The speaker’s blog. The language used to describe relationships needs to be richer, whilst still being diplomatic.
• Open coffee – a coffee meeting for people starting up. Runs every second Thursday.
• Twitter – got a quick intro to this. 140 character microblogging / updates. Max of 240 free SMSes per week in Australia.
• The bar opened, and I played 3 rounds of the Werewolves + Seekers + Healers + Villagers game (rules are here or here, we played with a healer), which was a fun social game. There were between 11 and 15 people at the start of each round. It just confirmed what I always known – that I am a really bad at deception – I was found out fairly quickly when I was a werewolf!
