Off Facebook Activity

Off Facebook Activity is a tool, that let’s Facebook users see which sites they used outside of Facebook. The tool is as creepy as you would think it would be. Facebook, through it’s like buttons and other embeds, has sheer unlimited insight into personal browsing behaviour.

In an attempt by the company to create more transparency, it discloses how much curiosity in a negative sense is driving the social network in trying to understand their audience. And actually sell this gained knowledge to their customers.

The release of Off Facebook Activity a reminder we are living in an increasingly connected world that is watching us. There is entirely no point for any company to collect this type of data outsire of making us a product.

The Washington Post writes about how creepy and scary this feature is, and even more important, how to work with privacy settings. While the article deals with Facebook internal settings alone, the amout of data transferred to Facebook won’t stop. At this point, you may want to consider personal privacy tools like uMatrix (for Firefox or Chrome). Or, to leverage protection for the entire network, e.g. for your family, Pi-Hole is worth taking a look, too.

The Y2038 Problem

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
Calendar

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

Amazon CloudFront launches new Edge Locations

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.
