EU: EV charging infrastructure construction lags behind

The EU audit agency recently said that the deployment speed of electric vehicle charging infrastructure in the EU region is lagging behind, and the goal of adding 1 million charging piles by 2025 may be difficult to achieve. The European Commission announced this target early last year and plans to cut greenhouse gas emissions from transportation by 90% from 1990 levels by 2025. However, according to the investigation of the European Court of audit (ECA), the number of new charging piles in 27 EU countries and the UK is only 36000 each year, which has increased from 34000 in 2014 to 250000 by September 2020. If calculated according to the current deployment speed, the target of adding 1 million public charging piles by 2025 will face major risks. In fact, it will take about 150000 new jobs a year, equivalent to about 3000 a week, to narrow the gap. The [...]

Apple has launched a signature update for the old app to make it available on IOS / iPad OS 14.5

Some Apple iPhone users may have noticed that some apps that haven't been updated for a long time have been suddenly updated recently. One of the possibilities is that developers are actually working, and more likely, apple is officially updating. Apple is currently updating code signing certificates for older apps to enable them to run on IOS / iPad OS 14.5. Apple has launched a signature update for the old app to make it available on IOS / iPad OS 14.5 This update does not require the developer to re sign the deployment. Instead, Apple will officially issue a new signature. Users will receive a "this app has been updated with the latest signature certificate by Apple". In addition, apple warned developers of these old apps to release new versions as soon as possible.

Apple will use random serial numbers for new products to remind dealers to be prepared

Apple is reminding its authorized senior dealers and distributors to prepare for new products with 10 and 12 digital serial numbers. The company will hold a new product launch on the 21st of this month. Apple plans to switch to random serial numbers for future products from early 2021. The company now appears to be preparing for this plan, and in a memo obtained by macrumors, apple told authorized dealers and distributors to ensure that their "systems, warehouses and processes are in place to receive and deliver both serial number formats.". Apple currently uses a 12 digit serial number format for its products. Although this alphanumeric format is random on the surface, it actually contains key production information such as production date and time. With the new random serial number format, such information will be more difficult to decipher. Apple said the format would initially start with 10 bits.

Scientists unravel part of mystery radio source It wasn't an alien knock on the door

Is there any extraterrestrial civilization in the vast universe? Is there an alien with a big head, big eyes and a small chin hiding somewhere in the dark? It's a question that has crossed almost every modern mind at one time or another, and it's not just a science fantasy. It's a question that serious science is trying to crack. More than a decade ago, astronomers discovered a mysterious type of radio waves from outside the Milky Way galaxy. These radio waves, which flash for just a few milliseconds, are capable of emitting the energy that the sun emits throughout the day, eclipsing many celestial bodies in the universe. Astronomers call these radio astronomical phenomena of unknown origin fast radio bursts. Is this a signal sent to Earth by aliens? Some people put forward the basis of judgment: millisecond radio pulse, the arrival time and direction of the earth is [...]

The new batteries charge 10 times faster than lithium-ion batteries

Scientists at St. Petersburg State University in Russia have developed a new battery technology that not only allows batteries to charge up to 10 times faster than lithium-ion batteries, but also has little effect on battery capacity at low temperatures. Oleg Levin, an electrochemical researcher at St. Petersburg State University, says the key to the new battery is a REDOX polymer based on nitrogen oxides, which in a series of experiments has been shown to charge batteries 10 times faster than lithium-ion batteries. The REDOX polymer used is Ni-Salen (a combination of nickel and Salen), a metallic polymer that undergoes reversible oxidation (loss of electrons) and reduction (gain of electrons) during discharge and charge. The researchers say that in experiments, the technology not only greatly accelerated the charging rate of the battery, but also worked well at low temperatures, with little effect. However, the current drawback is that the battery's [...]
