As you probably didn't get enough of Kryptoradio in our previous session, it's time for a redux. In brief Kryptoradio provides means to stream stuff over DVB-T network of Finland. Beyond Bitcoin block chain, you can transmit stuff like ASCII art or entire websites even.

Given the last time was sort of theoretical we thought maybe it would be nice to actually do something instead of contemplating future possibilities. That is where Revenge of Kryptoradio comes in. In this session we will take a hands on approach and actually try to build something on top of the technology.

I will be focusing on stuff such as React.js, D3.js and possibly webpack and show how to build a graphing thingy on top of Kryptoradio API. There is no rigid schedule and it's more about exploring technology than nodding in agreement. It might be useful to bring your laptop.

See you at Hemingways on Thursday 30.10 starting from 18:00. I'll go likely grab a bite around five in some nearby joint. If dinner sounds alright, let's arrange something over IRC at #geekcollision (@IRCnet of course).

GC v0.40 Kryptoradio

Hey, o-hoy, fellow geeks and comrades and radio amateurs and whoever is tuning in. For the version 0.40 we have a little something special in store as Joel Lehtonen will introduce his Kryptoradio project that has already made history.

Kryptoradio sends Bitcoin transactions through 90 of Digita's TV broadcasting stations. The broadcast is a pilot to evaluate the suitability of digital television network for transmitting payment data and to enable application development. Broadcast data includes Bitcoin transactions, blocks and exchange rates with regards to the most common currencies. These enable the reception and monitoring of Bitcoin payments without an Internet connection, which enhances the reliability of payment confirmation.

In GC meeting Joel will walk us through the basic concept of Kryptoradio and how exactly one can join in on developing applications for it. Kryptoradio has an HTTP interface that enables development with technologies already familiar from web development.

We'll be starting around 6PM next Wednesday the 8th, for presentational reasons in Hemingway's (the one on Kauppakatu).

TL;DR: Kryptoradio, bitcoin broadcasting via TV network, introduction Wed 8.10.2014 in Hemingway's Kauppakatu starting 6PM.

GC Adventure Time

It's been a long time since the days of our sauna ferry day, and I figured it could be nice to arrange some kind of communal activity again. They opened an adventure park in Laajavuori where one crosses and passes various obstacles on a roped course. Sounds like proper fun, eh?

There's not much information on the place in English yet, just that there are 5 trails and 62 barriers along the way. You can view the gallery at http://www.laajis.fi/seikkailupuisto/galleria/. The place is open on Tue-Fri 15-20, Sat 10-18 and Sun 12-18. There are also some special adventure nights coming up but they don't have any dates up yet. The tickets are some 20-26eur, depending on how many we are and are you renting gloves or not.

Vote for suitable times at http://www.sumpli.com/p.php?i=d4dcc21d9ace110. Feel free to suggest other options for activities and/or dates e.g. on the mailing lists or on IRC.

Introduction to Negative Testing and Security Tools at Mon 26.5 18:00-

Generally if people test, they test the happy path. What if something doesn't go as planned, though? How can you be sure the code won't explode on some boundary condition you didn't think of?

That's what negative testing, and fuzzing in particular is about. Our friend from the company who discovered Heartbleed will provide us an introduction to the topic. In addition we will have someone from the local university of applied sciences to show some security related tools and talk about OWASP.

The event will be held on Monday 26th at Hemingway's starting from 18:00. Even if you didn't make your mark to the Doodle, consider showing up. It should be a fine session and might change the way you think about testing.
