The AWS Global infrastructure is built around Regions and Availability Zones (AZs). AWS Regions provide multiple, physically separated and isolated Availability Zones which are connected with low latency, high throughput, and highly redundant networking.

Along the journey of learning Junos, you will run across different routing tables that are used for different purposes. Some tables make sense right away, but others take some digesting. I hope I c…

Device-independent quantum key distribution provides security even when the equipment used to communicate over the quantum channel is largely uncharacterized. An experimental demonstration of device-independent quantum key distribution is however challenging. A central obstacle in photonic implementations is that the global detection efficiency, i.e., the probability that the signals sent over the quantum channel are successfully received, must be above a certain threshold. We here propose a method to significantly relax this threshold, while maintaining provable device-independent security. This is achieved with a protocol that adds artificial noise, which cannot be known or controlled by an adversary, to the initial measurement data (the raw key). Focusing on a realistic photonic setup using a source based on spontaneous parametric down conversion, we give explicit bounds on the minimal required global detection efficiency.

While searching for your next GNU/Linux enabled computer, you may have found that some vendors such as Dell, HP and Lenovo sell a selection of desktops and laptops with Ubuntu pre-installed. In fact, Ubuntu is certified on an ever-growing list of hardware. But what does it mean exactly for such a device to be “Ubuntu  […]

My program received a SIGSEGV signal and crashed with "Segmentation Fault" message. Where does the "V" come from?

Did I read it wrong? Was there a "Segmentation *V*ault?"? Or did Linux authors make a mistake? Shouldn't the signal be named SIGSEGF?

The previous record for the largest DDoS attack ever recorded was of 1.7 Tbps, recorded in March 2018.

[edit] And now you can hear the bell(s)! Actually a whole episode on it: https://youtu.be/b2QPy-igBLA

Some commenters requested that we use our restored vintage 1930 Model 15 Teletype as a terminal for Linux. Hooking up a 5-bit Baudot mechanical contraption to a modern OS, even one that is terminal friendly, is not without some challenges: adapting to the non-standard high voltage 60 mA current loop, interfacing ASCII to the much smaller and different Baudot encoding, working in all caps, dealing with Baudot FIGS and LTRS modes, and making sure the computer doesn't overrun the pokey 45.5 bauds connection. But hey, Unix was developed on (much more modern 8-bit) teletypes, so that should still work, shouldn't it?

The bell can now be heard playing the Teletype March: https://youtu.be/b2QPy-igBLA
