I am performing some site maintenance in conjunction with a move to a new VPS server. (Thank you Hetzner (some irony may be involved)).
Hopefully everything should be reachable, but some minor UI tweaks may occur.
Thanks for understanding.

Last week Howard Marks completed the Hyperconverged Infrastructure Deep Dive trilogy covering smaller HCI players (including Cisco’s Hyperflex) and explaining the intricacies of costing and licensing HCI solutions.
On Thursday I finally managed to start the long-overdue Data Center Interconnects update. The original webinar was recorded in 2011, and while the layer-3 technologies haven’t changed much (with LISP still being mostly a solution in search of a problem), most of the layer-2 technologies I described at that time vanished, with OTV being a notable exception. Keep that in mind the next time your favorite $vendor starts promoting another wonderful technology.
You can get access to both webinars with standard ipSpace.net subscription.
ExFaKT: a framework for explaining facts over knowledge graphs and text Gad-Elrab et al., WSDM’19
Last week we took a look at Graph Neural Networks for learning with structured representations. Another kind of graph of interest for learning and inference is the knowledge graph.
Knowledge Graphs (KGs) are large collections of factual triples of the form
(SPO) about people, companies, places etc.
Today’s paper choice focuses on the topical area of fact-checking : how do we know whether a candidate fact, which might for example be harvested from a news article or social media post, is likely to be true? For the first generation of knowledge graphs, fact checking was performed manually by human reviewers, but this clearly doesn’t scale to the volume of information published daily. Automated fact checking methods typically produce a numerical score (probability the fact is true), but these scores are hard to understand and justify without a corresponding explanation.
To better support KG curators in deciding the correctness of candidate facts, we propose a novel framework for finding semantically related evidence in Web sources and the underlying KG, and for computing human—comprehensible explanations for facts. We refer to our framework as ExFaKT (Ex Continue reading
In this post we’re going to talk about how to run the amazing stunnel program on your Android device, and do so properly!
Later, this would allow us to setup a lot of cool things like:
For this, we’re not going to use the old and very limited SSLDroid. It’s a bad idea, I don’t know why different sites still keep pushing it. It almost certainly has unpatched vulnerabilities. Please don’t use it.
Instead, we are going to use the official stunnel program, with the help of a proper wrapper.
stunnel already supports Android devices and even the compiled version of it is available in it’s download page.
Since we’ll be using the compiled binary, you may need to compile stunnel yourself for your specific Android architecture before continuing1. Chances are though, that your device is running on ARM and you are ready Continue reading

In our last post we covered the basic setup and configuration of ExaBGP. While we were able to make use of ExaBGP for dynamic route advertisement, it wasn’t able to help us when it came to actually programming the servers routing table. In this post, I want to show you how you can leverage ExaBGP from a more programatic perspective. We’ll start by handling route advertisement to our peer and then tackle reading and processing received route updates. We’ll also start using another Python module (pyroute2) to program the routing table of the bgp_server host so that it begins acting more like a normal router. Enough talk – let’s dive in!
Im going to assume you’re starting off at the end of the last post. So the first thing we need to do is clean up a couple of items. We’re not going to rely on the static route we provisioned so to clean that up we can simply reapply the netplan network configuration using the command sudo netplan apply…

During the second half of 2018, the causes of significant Internet disruptions observed through the Oracle Internet Intelligence Map could be clustered into a few overarching areas: government-directed, cable problems, power outages, distributed denial of service (DDoS) attacks, and general technical issues. Little changed heading into 2019, with two new government-directed Internet disruptions observed in Africa, alongside disruptions caused by fiber cuts and other network issues that impacted a number of countries around the world.
Initially covered in last month’s overview, the Internet disruption in the Democratic Republic of Congo continued into January, lasting through the third week of the month. Government authorities reportedly cut off Internet access in the country in December to prevent “rumor mongering” in the run-up to presidential elections.
An attempted military coup in Gabon led to a day-long Internet disruption in the country. The disruption started just after 07:00 UTC on January 7, as seen in the figure below, which shows clear declines in the Traceroute Completion Ratio and BGP Routes metrics, as well as a disruption to the usual diurnal pattern seen in the DNS Query Rate metric. Although the coup Continue reading
