And here is one more post about my 32C3 experience at the end of last year in Hamburg. This was the first conference I did not only “attend” but was actually “a part of”. There is a big difference between the to approaches: Normal conferences are fully organized and you go there to listen to … Continue reading 32C3 – An Angel In Retrospect – Being Part Of The Conference Instead Of Just Attending
Like ever year at the end of the Congress one of the last sessions is the Infrastructure Review. Here, the people who built the congress data network, the DECT network, the GSM network and the Seidenstraße talk about the technology they used this year. It always interesting to hear how much data, calls and packets … Continue reading 32C3 – Congress Infrastructure Review And A Plea for GSM ARFCNs for 2016
One feature some proponents are pushing for future 5G networks are ultra short reaction times for ultra critical communication, for example between cars. What I failed to understand so far in this discussion was why for car to car communication a fixed network infrastructure and a backhaul network was necessary!? After all, car to car … Continue reading 32C3 – Vehicle2Vehicle Communication with IEEE 802.11p
My 32C3 discovery of the day: I’m not quite at the end of my Nibbler discoveries yet but I’ve just figured out how I want to continue my hardware adventures by climbing up the CPU ladder just a bit to something with interrupts and a real hardware stack: Voja Antonic’s ‘DIY Single-chip 2D Retro Game … Continue reading 32C3 – A One Chip Retro Console For Assembly Programming
12.000 people have bought tickets for the 32C3 and while they consumer a lot of data from the Internet it's easily dwarfed by the amount of data that is flowing from the congress to the outside world. How much of that are the live and recorded video streams is hard to tell but I guess … Continue reading 32C3 – Approaching 20 Gbit/s of Outbound Traffic
It's day 2 of the 32C3 in Hamburg and I'm really happy that I was able to attend in person this year. My previous tip to use a 5 GHz Wifi capable Android phone as a WiFi USB dongle for my notebook has paid out as the 2.4 GHz range is hopelessly overloaded in most … Continue reading 32C3 – Recommended Videos of Day 1
It almost time for the 32C3 now and I'm on my way to attend in person this year. One thing the organizers have kept pointing out over the last few years is that due to the very limited spectrum available in the 2.4 GHz band, the network experience will be rather mediocre in this band. … Continue reading No 5 GHz Wifi in Your Notebook For 32C3? Use Your Smartphone As A Wi-Fi Dongle over USB!
And finally, here’s part 3 of my series of entries on what moved me in 2016 technology wise. While part 1 and 2 focused on networks and Linux computing this part deal with a few miscellaneous things.
Back in December I returned from 32C3 with a DIY retro game console kit created by Voja Antonic as it promised to be fun to assemble and to study the source code. To me it was “the” hardware discovery of the congress! Apart from the prospect of playing a retro-game and to feel transported back … Continue reading The DIY Retro Game Console Revisited
Back in December 2015 I found my first public Wifi network at 32C3 that used a certificate instead of a common password, not so much for user authentication but for assigning an individual ciphering key to each device. Especially at a hacker conference that’s a plus as normal WPA encryption uses the same passphrase for … Continue reading Eduroam – Wifi With A Certificate And Cool Roaming Features
