Regional Pitchfest Information Night at CoWS – Thurs April 27th at 6:30PM

Regional Pitchfest ImageA nationally significant StartUp pitching event visits Bega in a fortnight’s time, on April 27th. The Regional Pitchfest (regionalpitchfest.com) team, headed by Di Sommerville will present an information evening on the programme, and, for maximum fun, oversee some practice pitches on the night.
Pitches are only 1 minute long…so get practicing if you would like to do one on the night, or just rock up and pull one out of your proverbial there and then.
Please register here – https://www.stickytickets.com.au/51751
The competition has a finals event in Wagga in August.
Let us know if you are attending – we are expecting to have about 10 to 15 people pitching on the night.

08:30 AM Breakfast and Networking
09:15 AM Brendan to compere…
    • The 12 skills of Christmas’ – introduce the new batch of skilled sea-changers…one by one…and they speak for 3 minutes…and perhaps, for another minute they field a question from the audience, or chat with Brendan

10:15 AM Quick break to refill people’s coffees?

10:30 AM Brendan to deliver 30 mins ‘How to run a startup from the regions – tips and tricks’
11:00 AM Brendan to live mentor 3 lucky people…we can organise them prior, or pick them from the audience.
11:30 AM More Networking
We are offering breakfast to the attendees (or at least the first 20 to register on Eventbrite)….
More details about Brendan…here are the details of his previous visit in August…
“How to be a Rockstar Founder”
Brendan Yell
Director, Community Development, SoftLayer
Founder, ShopFree.com
Mentor @ Muru-D, Amcomm Upstart, Slingshot, Jumpstart, TechBeach
After creating an online service for use of his friends at age 14, working at CompuServe at age 21, running Optus Interactive Strategy at age 25, then founding and lauching ShopFree.com at age 27, there is not much Brendan Yell has not seen.

Bega High School Work Experience – A Load Balanced Web Server

This week we have been given the opportunity to conduct our work placement for I.T VET at 2pi Software. Within these days we have been able to set up a small web server running an Odroid as the master system, which had a load balancer installed, using Nginx, to evenly spread the traffic from incoming requests.

A load balancer is a device that evenly distributes incoming traffic between nodes. This increases the amount of requests and will increase the reliability of the server, which is critical for a company’s efficiency for their online presence. A company that uses load balancing is Google, which would have a massive load of requests being sent to the servers, which will then have to be evenly distributed across all their servers.

The requests were then distributed across 3 different Raspberry Pi systems, low cost, high availability micro computers that allow users to achieve goals such as learning basic coding to more experienced projects like creating a mini arcade machine.

These were then benchmarked to see how much stress the server will be able to take when under a heavy load of requests. We recorded our results and then compared the data to make sure the nodes were running at the same efficiency.

Also during the week we were given the task of making a MySQL database which was hosted on the Odroid to observe how the web server could handle the load of running a MySQL database with PHP.

Setup

Our setup looks like this:

The 3 Raspberry Pi’s

Results

We ran multiple tests using different types of media, these include:

  • Static HTML
  • Static HTML with an image
  • PHP
  • PHP and MySQL

The results we collected are below, where data presented ranges from the 50th to 100th percentile. The number on the right of the percentage indicates the response time in milliseconds.

These results show that using more complex web tools will slow down the web server significantly. This is shown in the odroid with PHP & mySQL  which has results that are double of the static HTML.

Cool Digital Music Demo and Project at upcoming coding night (Thurs 7th May)

The centrepiece of this upcoming coding night is an exciting project…and will be delivered by Steve Ryan. Please read Steve’s description below…it’s a terrific project….

 

Hey all,
so having met Scratch for drag and drop programming I wanted an easy way to enter longer pieces of music as Scratch blocks so I could integrate animations with the music.

http://abc2scratch.2pihosting.com/ is a javascript app (https://github.com/syntithenai/abc2scratch) to help by taking abc notation, rendering as music notation and offering export to scratch blocks.

http://abcnotation.com/ describes the text based ABC format for writing music and provides heaps of examples.

I’m running a demo next coding night taking an ABC tune from the web, adding parts and animating it in Scratch.

I’ve recently aquired a Lego EV3 and I’d love to connect scratch and coreograph dancing robots. I’m having trouble getting s2bot working to extend Scratch to provide EV3 blocks. Any experience out there?

Having had trouble with quicktime playback of midi, I’ve included a pure javascript midi playback solution using soundfont files. (currently broken but I have had it working – pull request on git anyone?). Scratch seems to do timing well when playing generated notes but not so well on the timing of playing back recorded sounds. Any experience ?

If anyone is interested I’d like to arrange a Scratch band by combining a bunch of musical sprites into a composition. To get the ball rolling I’m calling for musical sprites

  • The must in the key of C so all the sprites overlay in harmony (more or less). Mostly this means that the sprites last musical note must be C.
  • The sprite must be 1,2,4,8 or 16 bars length.
  • The sprite must be categorised (in it’s filename) as rhythm, bass, harmony and melody. Typically a melody part would be 16 bars.
  • The sprite must have costumes indicating active/inactive that are shown when the music starts/stops. More costumes or other animations throughout the musical fragment are encouraged.

For those with skills in music notation, another project could be a 12 bar blues.

CoWS Coding August 2014

Harry running his Clojure programming Workshop as part of National Science Week.

Having fun at CoWS!!!

Scratch and some Raspberry Pi hacking scheduled for tomorrow too.

And CoWS also featured in an article in StartUp Smart – some insights into tech ‘in the sticks’ and the plus’s and minus’s of trying to create disruptive businesses in regional Oz. Check out the link here.
