The internet has been recently flooded with websites trying to create various statistical information regarding the new coronavirus. Just within the Czech register, there are several. If you are on of the people who like to follow latest “coronavirus” numbers or if you use them in your work, you can face multiple obstacles. Some of the statistics give you the data you need, but they are outdated and are not regurlarly refreshed. In case of dynamic visualizations, you are limited by fixed boundaries. If you are not satisfied with that, you can try a newly created tool for generating dynamic visualizations from the CZ.NIC Association that offers a broad set of features and settings. You can for example choose any country/region and a formula for your desired curve, copy URL and of course refresh the data simply by pressing F5. Everything you can find on the web page https://covid-19.nic.cz/.
Looking back at the Cybercompetition finale
A golden opportunity: the bank we’re about to rob is moving to new premises today. To our luck, they’re also testing alarms until 4 PM, so it won’t be suspicious if we accidentally set one off. There is an open window on the first floor protected by a single sensor. Our inside man among the staff has placed an IP camera into the sensor cabinet, so we can see if the sensor we are trying to break has the ‘status OK’ or the alarm is screaming. The IP camera is streaming to YouTube — alas with a delay. The problem is that the sensor communicates via radio waves: every 15 to 30 seconds the diode beeps and the device sends a signal. We’re listening, trying to imitate it, and when we’re sure, we’re gonna shut down the sensor and turn on our little imitation that we built. What is left is just to arrange the tin foil between the antennas, like this… the sensor alarm’s blaring! We are holding our ears and will try again in half a minute.
