Category: Internet & Cloud. This brand new thing: Internet & Cloud. Even though the technology is around for way more than 30 years, it is a never drying source of news and discoveries. The new channel of communication created a entirely new culture and created new businesses, fueling innovation and creativity.
All those things that clearly relate to something ‘new media’, items and thoughts that would not have been possible without the internet, will go here.
The Y2038 problem is similar to the Y2K problem. We’re exactly in between both about now. Both are 18 years away, in either direction. While Y2K is over and was obvious to everyone, Y2038 is not.
The issue here relates to a representation of date and time in Unix systems, and is therefore sometimes referred to as Unix Y2K. The root is the convention to store date and time information as 32bit unsigned integer in such systems. This means, possible values are limited. Time-differences in seconds, starting from 01.Jan 1970 cannot span beyond 03:14:07 UTC on 19 January 2038.
The Y2038 problem will make all calculations beyond this date impossible, until migrated to another representation. At the time being, this seems far away. However, the problem casts its shadows already. Industries, in particular financial markets, often rely on long term forecasts.
Governance issued treasury bonds come with with the longest maturity. Often twenty years, sometimes thirty years. Calculations for complex, long running financing models easily try to estimate returns 20 years and beyond into the future. This is already beyond the problematic date that Y2038 brings. The code to run these calculations is typically complex and stable. Sometimes, it is as old as from 1970. Back then, this date-representation Unix engineers introduced this approach. 32bit covered a long period. John Femellia has a thread, over at Twitter, telling a story about the upcoming issues today.
Amazon CloudFront Edge Locations: AWS’ Amazon CloudFront launches 5 new CloudFront Edge Locations. These are located in Bulgaria, Greece, Hungary, Kenya, and Romania.
AWS CloudFront is a Content Delivery Network and helps webpages to distribute their content globally. To achieve this, CDN’s leverage managed reverse proxy servers. The goal is to bring content closer to the consumer. And through keeping bulky media distributed, it prevents congesting internet connections.
These added deployments will help AWS customers and their consumers experience significantly improved page load times. AWS has constantly expanded CloudFront’s Network footprint since its launch in 2008. With this recent update, CloudFront now has 216 points of presence in 84 cities across 42 countries.
Arduino launches IoT platform: With the Portenta H7 Arduino announces a Platform targeted at small and medium businesses. It comes with all the connectivity necessary to enable devices classified as Internet of Things: WiFi, BLE, with physical connectivity to USB and SD-Cards, plus the well known Camera or UART connectivity. TechRadar also mentions LTE. Here is the article from TechCrunch:
Arduino, the open-source hardware platform, today announced the launch of a new low-code platform and modular hardware system for IoT development. The idea here is to give small and medium businesses the tools to develop IoT solutions without having to invest in specialized engineering resources. The new hardware, dubbed the Arduino Portenta H7, features everything […]
12:50 dreiwert and Claus Diem share ideas about Provable Insecurity and Cryptographic hash functions and the problems modelling them for the real world. Claus is a mathematician and cryptographer, who, among others, worked on designing and analyzing a novel attack on elliptic curve cryptography.
In Saal Ada erzählen Peter Schmidt und Heurekus schon um 11:30 über dem Weg von 4G zu 5G und den notwendigen Wandel im Core Netz. Im wesentlichen erklären die beiden dabei Unterschiede der beiden Protokolle an der sogenannten Luftschnittstelle, inkl. der Vor- bzw. Nachteile.
14:10 Das nützlich-unbedenklich Spektrum Fefe teilt seine Gedanken zu Softwarequalität und Legacy Code, in dem er Software zwischen Nützlich und Unbedenklich einteilt. Auf dem Gedankengang dahin erörtert er mehrere Dimensionen, die man für eine Bewertung heranziehen kann.
16:10 The ecosystem is moving Moxie Marlinspike, Gründer von Signal, dessen Crypto-Protokoll sogar in WhatsApp Einsatz findet, über Messenger: distributed and decentralized technologies from the perspective of a product that many would like to see decentralize. In his talk, Moxie Marlinspike, makes an argument against decentralizing. He argues with four (4) individual talking points and invalidates all four of them throughout the talk:
Unsurprisingly, the crown in the room disagreed.
17:10 Die Zukunft grenzüberschreitenden Datenzugriffs und politischer Verfolgung Elisabeth Niekrenz politische Referentin der netzpolitischen Organisation Digitale Gesellschaft e.V., über eine in Brüssel gegenwärtig verhandelte Verordnung, die Zugriffe auf Benutzerdaten Grenzüberschreitend regeln soll.
After having traveled for a few hours, we missed the opening ceremony but still had a few good first impressions. Here are a few notes from what I managed to see so far at Day 1 at the 36C3 in Leipzig:
16:10 The Large Hadron Collider Infrastructure Talk Sev and Thasti give an insight into how the Large Hedron Collider at CERN works. LHC is a particle collider that measures about 27km in diameter and requires – if I got the two speakers right – 450kV of current off the French electricity grid. The particle beam produces enough energy to melt 1000kg of copper, when turned on.
17:30 From Managerial Feudalism to the Revolt of the Caring Classes: David Graeber, author of Debt: The First 5000 Years and Bullshit Jobs is talking about how the caring classes, e.g. health and education, are becoming increasingly less appreciated and how administration is on the rise.

21:00 What the world can learn form Hong Kong. Katharin Tai talks about backgrounds of the Hong Kong protests and explains the 5 demands of protestors. The clarity helps the movement keep their momentum and stand against government. She also gives insights into strategies to cope with police and organisation of the protests, that are ongoing for months now. So is “Be water”, a phrase apparently inspired by Bruce Lee, a tactic to organise flash mob type protests. Plenty of these ideas are reflected in Hong Kong Protest Art, that Katharin Tai also covered in her talk.
David Belson, former Akamai Internet Analyst, now working for Internet Society, explained “Internet Shutdowns” in his latest blog post.
In March 2019, in a move described in one news report as a “government-imposed Internet shutdown,” the president of Sri Lanka temporarily blocked Facebook, WhatsApp, Instagram, Viber, and other services. In this case, limited access to a class of applications was inaccurately painted as a full-scale Internet shutdown. Unfortunately, this isn’t unusual. Media coverage and […]
