Pixels Camp 2016

A few weeks ago took place in Lisbon the first edition of Pixels Camp (aka Codebits 2.0), an event that I try to attend whenever it happens (see previous posts about it). It is the biggest technology focused event/conference in Portugal with a number of attendees close to 1000.

This year the venue changed to LX Factory, even though the place is really cool, it is not as well located as the previous venue, at least to people who don’t live in Lisbon and arrive to the airport. The venue was well decorated and with a cool atmosphere, giving you the feeling that it was the place to be. However, this year there was less room for the teams working on the projects and not everybody was able to get a table/spot (it appeared to me that the venue was a little bit smaller than the previous one).

From the dozens of great talks that were given on the 4 stages of the event, many of whose I was not able to see since I was competing in the 48h programming competition, bellow are two that I really liked:

Chrome Dev Tools Masterclass

IPFS, The Interplanetary Filesystem

If you have some curiosity you may find the remaining on their youtube channel.

All this is great but the main activity of Pixels Camp is the 48h programing competition and this year we had another great batch of cools projects being developed (total of 60, if I remember correctly).

As usual I entered the contest, this time with the fellow Whitesmithians, Rui and Pedro. We chose to develop a GPS based game, you know, since it seemed to be a popular thing this summer and we though the medium still has great potential to do really entertaining stuff.

The idea already had a few years but never had been implemented and at its core was quite simple. It took some ideas from the classic game “pong” and adapted it to be played in a fun way while navigating through a real world area.

We called it PonGO and essentially the users must agree on a playing field, such as city block, a city or even bigger areas, then they connect their phones and the ball starts rolling. The players have to move around with their phones (which they use to see the map and track everyone’s position) trying to catch the ball and throw it to the other side of the map. The player that is able to do it more times wins the game. Here is sketch we did while discussing the project:

As you can see in the above image, that would be on the phone’s screen, the player (in yellow) reached close enough to the ball so it can play it, now he has to change the direction to one of the opposite sides (marked as green). The other players (in blue), will have to run to catch the ball before it gets out. Spread across the map you can see some power ups that give users special capabilities.

That’s it, it might seem easy but doing it in less that 48h is not. We ended with a working version of the game but the power ups were not implemented due to time constrains. Here are some screenshots of the final result(we used the map view instead of the satellite view so it might look a little different):

The code itself is a mess (it was an hackathon what were you expecting) and can be found here and here.

At the end, it was a great event as usual and I would also like to congratulate some of my coworkers at Whitesmith that took home the 7th place in the competition. Next year I hope to be there again (and you should too).

Codebits 2014

The 3 days passed so fast that i got the sensation that the event took place in only one day. The only regret I felt in this year’s event was related with the fact that our team was unable to get the project ready for the presentation in 48h.

We were developing a service that would  pay developers (using MEO Wallet) who contribute to open source projects, with bounties associated to specific issues, as soon as their pull request is merged in Github.

The rest of the event was awesome as always and all the speakers of the talks i was able to attend (Christian Heilmann, Miguel Duarte, Miguel Mota Veiga, …) were up to the job.

So next year the organization can count with my application to the event again.

This year’s project

Another year and another codebits edition has come and gone. This time i had to enter the 48h programming competition. So with André Gonçalves and some help of Carlos Santos, we tried to develop a new service that would help the users of MEO Kanal. The description of the service was the following:

Basically this project aims to develop a new way of managing your MEO Kanal (or several of them) through your cloudpt account. Giving you the ability to access all the functionality without the need of a browser or any additional software.

The way it works is simple, just give the permissions to the webapp (from MEO Kanal and cloudpt accounts) and you are ready to manage your channel from any devise which can upload files to cloudpt, by adding or removing files in the channel folder. The next video (we made it for the presentation) shows the basic usage of the app:

Since the project is not finished and the coudpt will not be available to the public till December, i will try, in the next few months, to complete at least the basic functionality and publish a prototype. You can access the code (and help) in the github repository of the project. So if you have any idea, opinion or want to give a little feedback, please use the comments.

Here i go again

Just take a look on what arrived to my mail box yesterday morning:


Like last year (and a little bit sooner this year) i had the privilege of being accepted for the biggest technology event here in Portugal. It will take place in Lisbon in the middle of November and i will be there, participating in the 48h hackathon, and this time trying to finish my project. So in the next two months I will be collecting ideas (comment box please, if anyone would like to share some) and preparing for a great weekend.

If you’re going too, see you there. If you didn’t applied yet, you only have 3 days left.

To Codebits here i go…

2_normalThat’s right folks, just look at that beautiful message at the screenshot.

I’m sure that the most famous 800 people tech event in the country will be an amazing weekend, with lots of interesting talks, people and some competitions that will push the participants to the limit. If in the next few weeks, some nice ideia comes to my mind, maybe i will try my luck in the programing competition. So i’m looking foward to it.

If you are one of the lucky ones too, see you in November at Pavilhão Atlântico.

P.S.: And yes i will accept the “Nuclear Taco” challenge
