The robot has stereoscopic cameras and can do face recognition, in that it recognises a face when it is in front of it. This means the robot will talk to you when you when it looks at you, although it cant tell one face from another by default. The robot has pressure sensors and fingers so it can interact with its environment.
London Scala user group
There were a lot of developers from LSug group and they ended up split into three smaller groups to focus on different problems.
Some of the team were working with MongoDB, some working on the RSVP via meetup. All the events displayed on the Lsug website can now be joined directly, without having to visit the meetup site. Perhaps the total number of Yes RSVP’s can be added to each meetup?
Coding Board is a small web application allowing developers to share code with each other in a hands-on session. When we want to talk about the decisions we took as we approached a problem, its nice to have the code itself shared on the screen in a syntax highlighted way.
- Scala and Scalatra
- Twitter Bootstrap for the front end framework
- Selenium Webdriver and Specs2 for “testing”
- Heroku developer cloud service for easy deployment
- and no persistence whatsoever..:)
The project is under an open source license and the code is available on Github for you to clone and fork.
Read a blog of the days events for this project from Balint Pato himself.
London Clojurians - getting going with Clojure
Two of us helped out a developer relatively new to Clojure, although they did have some past experience with Lisp. We helped them get ther environment set up, which was a bit more of a challenge as the were running Windows 8.
Luckily its still fairly easy to set up a working Clojure environment on Windows, although just about every command seemed to ask for the Administrators password! On the Leiningen website, there is reference to a 3rd party bat file for getting going with windows. The problem with this bat file is that its dependant on either wget or curl, neither of which were available on this machine.
We got round the problem by manually doing what the leiningen bat file did, downloading the .jar file and putting it in ~/.lein/self-install/…jar
A problem still remand with running lein. The version in the .bat file was different from the ..jar file, so lein attempted to use and download a different version, which it couldnt find. As we didnt have curl or wget to download the version in the bat file, we simply changed the bat file manually.
Some other aspects to setting up Clojure on windows 8 included:
- make sure javac is on the path, we only had java and lighttable failed
- install leiningen - there is a bat file or use cygwin
- install lighttable
- use lein to create a new project and connect to a REPL
Salesforce for charity
Another team formed around the Salesforce platform. The were developing a tool to extract data from charity sites like Virgin Just Giving, helping fund raising organisations improve their fund-raising capabilities and getting a better view on where funds were coming from.
The data captured is filtered for the valuable data and the tool would allow you to match the incoming data with existing information you have.
The project is open source and available on Github.
Java, Java, Java
A team was also working on Java and some of the technical activity around the Java Community Process (JCP). The JCP is a way for others to help shape the future of the Java language and define the specifications for the language.
Coding through the night?
I did wonder at one point if we would still be here coding through Sunday as there were teams coding well into the evening. By about 6pm everyone had got headed off into the beautiful London night.
Join us for the next HackTheTower event
Come along and join the fun. If you are a developer who likes to learn and share experiences with others, then all you need is a laptop and some enthusiasm (laptop optional).
