British consultant billing £650K/year. HMRC took £287K. His plan: "I'll become a non-dom." Non-dom rules got gutted in 2025. We moved him to Dubai. No personal income tax. He invoices through a US LLC. Banks in Singapore. Assets in a Nevis trust. From £287K in tax to £0. His old accountant said "you'll get caught." Caught doing what? Being legal?

Fun bit of Austrian trivia: The word for "Austria" in most European languages refers to the "Eastern Empire". The Czechs however reference the name of a castle near the border. Source: #lightbox" target="_blank" rel="nofollow noopener">reddit.com/r/MapPorn/comm…






🇺🇸A250e W177 Mercedes Plug-in Hybrid (2023) with a contactor counter zeroed at 20,000 km. This is an error we have encountered on all EV and hybrid vehicles since models dating back to 2010, which officially requires replacement of the entire battery system. In this specific case, for a customer from Milan, Italy, the cost exceeds €8,000, with the old battery required to be recycled and a new one manufactured—even though the cells themselves are fully functional. The error cannot be cleared using OBD tools, not even with Vediamo / DTS Monaco engineering tools, because there is no command available to reset the counter. Consequently, even the highest level of authorized service using Xentry cannot reset it. The BMS system is similar to those used in the Smart 453, EQC, and other Mercedes-Benz hybrids. Very often, this issue is actually a firmware bug: for example, a weak 12V battery can cause a 5V power glitch that corrupts the EEPROM, or the system may detect a fault that does not actually exist (as seen on the 453 EQ, for example, where after error “driving not possible” and after towing the vehicle later drives normally again). We opened the battery, identified a possible root cause, restored the battery, and performed an SPC processor firmware recovery. The vehicle started again, with the contactor counter error cleared. The method is invasive and requires a programmer. The cells are healthy, the vehicle continues to operate, the owner was spared €8,000 in costs, and miners were “saved” from digging new cobalt.
