RTX 3080, Big Nav, Ryzen 5000, PlayStation 5, Xbox Series X: pre-ordered chaos?

Coinbase Card: VISA Card with Bitcoins

The Coinbase Card wants to solve this problem and is a VISA-Debit-Card, with which you can directly access the credit in the Coinbase-Wallet. Coinbase works together with PaySafe and offers the Coinbase Card in six European countries, including Germany. Interestingly enough there is the ...

If you haven't seen it yet, don't worry, this text does not contain any spoilers. In the Netherlands Dolby Cinema has been around since 2014, now the technology is coming to Germany in the form of a completely new hall ...

Operate humidity sensor with photovoltaic & battery

Anyone who uses an air humidity sensor is first of all dependent on the proximity of a power socket. This can be avoided by using a solar cell and a rechargeable battery as a buffer. Basically, you should already have a functioning air data sensor - this can help you avoid a source of error, even if the fine dust sensor is not connected to the ESP8266 module in this article. In order to guarantee the 5 volt power supply of ESP8266 via ...

Vodafone Callya: top-up by bank transfer

Anyone using a Vodafone Callya prepaid card will sooner or later stumble upon the limited recharging options. But one can easily top up by bank transfer without having to use the service of Klarna ("Sofortüberweisung"), Paypal or a credit card. Klarna has managed without any scandals so far, but some banks prohibit the access data for online banking to third parties. Moreover, not everyone ...

Supervising: Experiences after 10 days

Since the Telekom at my location provides Supervectoring 35b as the fastest offer, I have booked the corresponding MagentaHome XL. The provision from a regular vectoring connection (100/40 MBit/s) was completely problem-free: on the announced changeover day, the Internet was gone for about 15 minutes, then the Fritz!Box 7590 synchronized itself again and since then, without reconnects, has reached stable 265.5 Mbit/s download and 42.5 Mbit/s upload. Net ...

Spectre & Meltdown: Processor vulnerability causes a stir

Two security vulnerabilities published by Google, which practically affect most of the current processors from various manufacturers, are currently causing a lot of fuss. As part of Project Zero with Meltdown and Spectre, security researchers at Google have published attack scenarios that can be used to exploit a vulnerability in current processors. Intel was the first to come under the spotlight - but the problem seems to be spreading to other processors as well.

FreeNAS Corral: Debian as a virtual machine

With FreeNAS 10 "Corral" a new system for virtual machines has been integrated. A template: Debian 8.4.0. Since a FreeNAS server is active most of the time anyway, you can easily replace a Raspberry Pi using the virtual machine feature. In addition, performance demanding applications like an OpenVPN server or a VPN gateway can be easily implemented. The setup is simple: there is a list of templates for ...

Congstar: no "all inclusive" roaming in sight

A few years ago, Fyve and Congstar were exciting alternatives in the networks of Vodafone and Telekom. Without current options, however, these providers are becoming increasingly unattractive. While it was possible to use LTE in postpaid tariffs for a while, at least with Congstar, the provider Fyve, which operates in the Vodafone network, never offered this option. Other prepaid providers that do not directly offer LTE to the brands of the major network operators are also unable to offer LTE at present, ...

Internet of Things for Cars: TankTaler in test

By means of a small adapter for the diagnostic port, various data can be read out and transferred to your own mobile phone. TankTaler offers a corresponding adapter, which I tried out. The idea of the ThinxNet GmbH from Munich, which markets the product "TankTaler", is actually quite simple: by means of an OBD adapter the driven kilometers are determined and if you have been to special places (like gas stations). Per kilometre driven ...
