Here's the summary for the wikipedia article you mentioned in your comment:

A betavoltaic device (betavoltaic cell or betavoltaic battery) is a type of nuclear battery which generates electric current from beta particles (electrons) emitted from a radioactive source, using semiconductor junctions. A common source used is the hydrogen isotope tritium. Unlike most nuclear power sources which use nuclear radiation to generate heat which then is used to generate electricity, betavoltaic devices use a non-thermal conversion process, converting the electron-hole pairs produced by the ionization trail of beta particles traversing a semiconductor.Betavoltaic power sources (and the related technology of alphavoltaic power sources) are particularly well-suited to low-power electrical applications where long life of the energy source is needed, such as implantable medical devices or military and space applications.

Here's the summary for the wikipedia article you mentioned in your comment:

KRACK ("Key Reinstallation Attack") is a replay attack (a type of exploitable flaw) on the Wi-Fi Protected Access protocol that secures Wi-Fi connections. It was discovered in 2016 by the Belgian researchers Mathy Vanhoef and Frank Piessens of the University of Leuven. Vanhoef's research group published details of the attack in October 2017. By repeatedly resetting the nonce transmitted in the third step of the WPA2 handshake, an attacker can gradually match encrypted packets seen before and learn the full keychain used to encrypt the traffic. The weakness is exhibited in the Wi-Fi standard itself, and not due to errors in the implementation of a sound standard by individual products or implementations. Therefore, any correct implementation of WPA2 is likely to be vulnerable. The vulnerability affects all major software platforms, including Microsoft Windows, macOS, iOS, Android, Linux, OpenBSD and others.The widely used open-source implementation wpa_supplicant, utilized by Linux and Android, was especially susceptible as it can be manipulated to install an all-zeros encryption key, effectively nullifying WPA2 protection in a man-in-the-middle attack. Version 2.7 fixed this vulnerability.The security protocol protecting many Wi-Fi devices can essentially be bypassed, potentially allowing an attacker to intercept sent and received data.

Here's the summary for the wikipedia article you mentioned in your comment:

This is the map and list of European countries by monthly average wage (annual divided by 12 months) gross and net income (after taxes) average wages for full-time employees in their local currency and in euros. The chart below reflects the average (mean) wage as reported by various data providers. The salary distribution is right-skewed, therefore more than 50% of people earn less than the average gross salary. Thus, the median figures provided further below might be more representative than averages. These figures will shrink after income tax is applied. In certain countries, actual incomes may exceed those listed in the table due to the existence of grey economies. In some countries, social security, contributions for pensions, public schools, and health are included in these taxes.

Standard-dynamic-range video (SDR video) is a video technology which represents light intensity based on the brightness, contrast and color characteristics and limitations of a cathode ray tube (CRT) display. SDR video is able to represent a video or picture's colors with a maximum luminance around 100 cd/m2, a black level around 0.1 cd/m2 and Rec.709 / sRGB color gamut. It uses the gamma curve as its electro-optical transfer function.The first CRT television sets were manufactured in 1934 and the first color CRT television sets were manufactured in 1954. The term "standard-dynamic-range video" was adopted to distinguish SDR video from high-dynamic-range video (HDR video), a new technology that was developed in the 2010s to overcome SDR's limits.

Here's the summary for the wikipedia article you mentioned in your comment:

"Kill Switch" is the eleventh episode of the fifth season of the science fiction television series The X-Files. It premiered in the United States on the Fox network on February 15, 1998. It was written by William Gibson and Tom Maddox and directed by Rob Bowman. The episode is a "Monster-of-the-Week" story, unconnected to the series' wider mythology. "Kill Switch" earned a Nielsen household rating of 11.1, being watched by 18.04 million people in its initial broadcast. The episode received mostly positive reviews from television critics, with several complimenting Fox Mulder's virtual experience. The episode's name has also been said to inspire the name for the American metalcore band Killswitch Engage. The show centers on FBI special agents Fox Mulder (David Duchovny) and Dana Scully (Gillian Anderson) who work on cases linked to the paranormal, called X-Files. Mulder is a believer in the paranormal, while the skeptical Scully has been assigned to debunk his work. In this episode, Mulder and Scully become targets of a rogue AI capable of the worst kind of torture while investigating the strange circumstances of the death of a reclusive computer genius rumored to have been researching artificial intelligence. "Kill Switch" was co-written by cyberpunk pioneers William Gibson and Tom Maddox. The two eventually wrote another episode for the show: season seven's "First Person Shooter". "Kill Switch" was written after Gibson and Maddox approached the series, offering to write an episode. Reminiscent of the "dark visions" of filmmaker David Cronenberg, the episode contained "many obvious pokes and prods at high-end academic cyberculture." In addition, "Kill Switch" contained several scenes featuring elaborate explosives and digital effects, including one wherein a computer-animated Scully fights nurses in a virtual hospital. "Kill Switch" deals with various "Gibsonian" themes, including alienation, paranoia, artificial intelligence, and transferring one's consciousness into cyberspace, among others.

Since 2010, the European Union has investigated several antitrust complaints against Google alleging abuses of its dominant position in breach of the EU's competition laws. Three complaints have resulted in formal charges against Google: those relating to Google Shopping, the Android operating system and to Google AdSense. Google has been found guilty of antitrust breaches in the three cases and has been fined over €8 billion. In 2020, the European Union has also launched a full investigation of Google's proposed acquisition of the fitness tracker and wearable health company Fitbit, under the EU Merger Regulation. The operation was eventually cleared on 17 December 2020 subject to conditions.

From May 2 to September 27, 2023, the Writers Guild of America (WGA)—representing 11,500 screenwriters—went on strike over a labor dispute with the Alliance of Motion Picture and Television Producers (AMPTP). With a duration of 148 days, the strike is tied with the 1960 strike as the second longest labor stoppage that the WGA has performed, only behind the 1988 strike (153 days). Alongside the 2023 SAG-AFTRA strike, which continued until November, it was part of a series of broader Hollywood labor disputes. Both strikes contributed to the biggest interruption to the American film and television industries since the COVID-19 pandemic. The lack of ongoing film and television productions resulted in some studios having to close doors or reduce staff. The strike also jeopardized long-term contracts created during the media streaming boom: big studios could terminate production deals with writers through force majeure clauses after 90 days, saving them millions of dollars. In addition, numerous other areas within the global entertainment ecosystem were impacted by the strike action, including the VFX industry and prop making studios. Following a tentative agreement, union leadership voted to end the strike on September 27, 2023. On October 9, the WGA membership officially ratified the contract with 99% of WGA members voting in favor of it. Its combined impact with the 2023 SAG-AFTRA strike resulted in the loss of 45,000 jobs, and "an estimated $6.5 billion" loss to the economy of Southern California.

Here's the summary for the wikipedia article you mentioned in your comment:

` From 2014 onwards, software which manipulated air pollution tests was discovered in vehicles from some car makers; the software recognized when the standardized emissions test was being done, and adjusted the engine to emit less during the test. The cars emitted much higher levels of pollution under real-world driving conditions. Some cars' emissions were higher even though there was no manipulated software. Scandals relating to higher-than-reported emissions from diesel engines began in 2014 when the International Council on Clean Transportation (ICCT) reported discrepancies between European and US models of vehicles. This began with the Volkswagen emissions scandal. Independent tests carried out by the German car club ADAC proved that, under normal driving conditions, diesel vehicles including the Volvo S60, Renault's Espace Energy and the Jeep Renegade, exceeded legal European emission limits for nitrogen oxide (NOx) by more than 10 times. ICCT and ADAC showed the biggest deviations from Volvo, Renault, Jeep, Hyundai, Citroën and Fiat.Researchers have criticized the inadequacy of current regulations and called for the use of a UN-sanctioned test called Worldwide harmonized Light vehicles Test Procedures that better reflects real-life driving conditions. The test only came into force in 2017, with critics saying that car firms lobbied fiercely to delay its implementation due to the high cost of meeting stricter environmental controls.Conservative Internal Market spokesman Daniel Dalton – who led the legislation through the European Parliament – described the previous regulations as "at best patchy and at worst ineffective." He further said that his latest 2018 report introduced a strong, transparent system to ensure cars are safe and meet emissions standards.

Since 2016, 38 out of 40 diesel cars tested by ADAC failed a NOx-test. `
