Adblock chrome10/7/2023 Google says Manifest V3 is "one of the most significant shifts in the extensions platform since it launched a decade ago." The company claims that the more limited platform is meant to bring "enhancements in security, privacy, and performance." Privacy groups like the Electronic Frontier Foundation (EFF) dispute this description and say that if Google really cared about the security of the extension store, it could just police the store more actively using actual humans instead of limiting the capabilities of all extensions. In January 2024, Manifest V2 extensions will be removed from the store entirely. Starting in January 2023 with Chrome version 112, Google "may run experiments to turn off support for Manifest V2 extensions in Canary, Dev, and Beta channels." Starting in June 2023 and Chrome 115, Google "may run experiments to turn off support for Manifest V2 extensions in all channels, including stable channel." Also starting in June, the Chrome Web Store will stop accepting Manifest V2 extensions, and they'll be hidden from view. Google's latest blog post details the new timeline for the transition to Manifest V3, which involves ending support for older extensions running on Manifest V2 and forcing everyone onto the new platform. The update is controversial because it makes ad blockers less effective under the guise of protecting privacy and security, and Google just so happens to be the world's largest advertising company. "Manifest V3" is the rather unintuitive name for the next version of Chrome's extension platform. Google's journey toward Chrome's "Manifest V3" has been happening for four years now, and if the company's new timeline holds up, we'll all be forced to switch to it in year 5. ![]() ![]() While there are a lot of good ad blocking extensions and applications on the market, it’s hard to find one more widely-used and well-received than Adblock.Isaac Bowen / Flickr reader comments 264 with Where can you run this program?Īdblock is an extension that can be used on Chrome, Safari, Firefox, and Opera web browsers.

In 2016, 13 years later after he built AWS, Jassy was promoted as the CEO of Amazon Web Services, his salary in 2017 touching $36 million, with the division making booming profits. In 2019, it was reported more than 80 percent of Germany’s listed DAX companies use AWS. Notable companies that use AWS include Apple, Adobe, BMW, Comcast, Capital One, Disney, Expedia, General Electric, Lonely Planet, McDonalds, NASA, Netflix, Nokia, Pinterest, Samsung, Spotify, Sony, Turner Broadcasting, Time Inc, Twitter, US Navy, Zillow among others. It now commands 33 percent of all cloud computing, with Microsoft at 18 percent and Google, at 9 percent respectively. By 2006, 150,000 developers had signed up to use AWS. But running its business with a lot of hiccups and cumbersome technology gave Bezos, Jassy and their team the confidence that they should come with a solution to solve problems that many other big and small companies have, and will have when they start and expand their business.ĪWS is offered to subscribers as an inexpensive, yet effective solution for procuring large scale computing capacity quickly than building an actual physical server farm. Amazon’s early customers were startups and the company built the business quietly and resiliently.Ĭloud computing was not a natural goal for Amazon, which started off as an online retail company. ![]() A lot of companies including huge corporate kings like Oracle dismissed the idea, but the concept proved to be successful eventually. He sought to simplify cloud computing into component pieces and offer them on rent to users, individuals and companies. It was created with the idea of redefining web services and the way companies bought technology. In 2003, Jassy founded Amazon Web Services, with a team of 57 people. ![]() He becomes the marketing manager of Amazon, back 1997. He went on to secure an MBA from the Harvard Business School.

In a letter to employees announcing the move, Bezos said: “I’m excited to announce that this Q3 I’ll transition to Executive Chair of the Amazon Board and Andy Jassy will become CEO. Dji mavic pro 4k video download10/6/2023 ![]() First, the standard Charging Hub only supports the Mavic’s 50W Battery Charger and Mavic Car Charger, while the advanced version also supports the 100W Battery Charger and Car Charger from the Phantom 4. There are two main differences between the two Charging Hubs. This gives you the fastest way of getting all your batteries fully charged. In order to fully charge the first battery as quickly as possible, the Intelligent Flight Batteries are charged in sequence according to their power levels, from high to low. The two Charging Hubs can both charge up to 4 batteries at one time. In conclusion, the Mavic's Intelligent Vision Positioning System requires fewer inputs and is therefore more robust in its functionality.ģ.What is the maximum distance and maximum flight speed at which the Mavic can fly while avoiding obstacles? Plants and trees do not reflect sound as well as other surfaces, causing the Optical Flow system’s ultrasonic sensors to be unable to gather altitude data. As the data is not compatible, an Optical Flow system may become confused.Īnother example is when the ground below the drone is covered by vegetation. When flying in over the balcony, drones using Optical Flow will receive data from two data sources that measure its height above the below surface differently – one being its height above the ground, and another the height above the balcony. In contrast, an Optical Flow system, requires information from ultrasonic sensors to supplement its view of patterned surfaces.Īn example to show the difference between the two systems is when the aircraft is returning to you while you are standing on a balcony. ![]() Even if the Mavic is unable to identify reference points on the ground, it can still rely on its forward vision sensors to hover. Therefore, it requires no more than a patterned surface and enough available light to be able to hover stably up to 13m above the ground. The Mavic combines dual forward and downward vision sensors to realize precision hovering.

Epic vs apple zoom call10/6/2023 ![]() It has expressed its displeasure with Epic for breaking the law by upgrading the game without their approval. Since its inception, Apple has maintained that its platform is fair. This is why, for example, Fortnite is directly available from Epic's store and other app stores such as Samsung's Galaxy App store. Google has made a direct reference to its Android blog.īecause of this openness, a developer can distribute on the Android platform even if he or she and Google disagree on business terms. With Android 12, it has made it very easy for users to download third-party apps. Google has been engaged in its way and has handled to remain relatively diplomatic about the situation. However, it has not received the same level of media critique as Apple. Yes, a lawsuit has been filed against Google as well.įortnite was consequently eliminated from the App Store. The Epic Games Store was created in part to demonstrate that Epic could perform with a lower revenue cut of 12 %.Įpic has declared war on both tech giants due to their large pay cuts. There is a massive investment in hardware, which is frequently sold below the price, and marketing strategies in a broad collaboration with publishers, but this does not enlarge to open platforms such as mobile devices and computers. While these are the global standard rates that are generally recognized, Tim had his two cents on the matter. Tim Sweeney queried the need for a 30% revenue cut for digital storefronts as early as 2017. Epic Games has demonstrated its brilliance by selecting its best-selling game for the trial to compel feedback from the tech giant. It has permitted Epic to maintain its established accounts for maintenance purposes. Even though the case is still being heard, Judge Yvonne Gonzalez Rogers has flatly denied Epic Games' application to host Fornite on iOS. The instance may take months of trials to resolve, but the investigations in the United States are making some headway. The company prepared a 60-page lawsuit and a video parodying the legendary "1984" commercial. Sweeney describes the case as the major bet of his journey in terms of concepts of a digital revolution if Epic Games wins. Sweeney confirmed in a discussion with CNN Business that the plan of action known as Project Liberty takes about seven months to put together. Epic Games has filed lawsuits in the United States, Australia, the United Kingdom, and now Europe. This sparked the #freefortnite campaign as well as a legal battle between the maestros. This restriction avoided 116 million of the game's 360 million players from accessing game updates. ![]() As a result, it decided to use its monopoly to force Fornite out of the App Store. This sneaky move allows players to avoid the App Store's payment system, and the consequences were visible within hours. If you bought something through a storefront, you didn't get this discount. Users that purchased V-bucks, the in-game currency, officially from Epic received a 20% discount. Tim Sweeney has long advocated for Apple receiving a larger part of the pie, and he sought to devise a method that either reduced income or prevented Apple from charging any fee.Įpic Games' most popular game, Fortnite, had a deliberate update on August 13, 2020. ![]() With the upgrade, the players were able to avoid paying Apple a 30% share on each purchase. What prompted the fight between Apple and Epic Games?Īfter Epic Games launched a software upgrade last year, the market leaders have been embroiled in a legal struggle. So, before we get to the conclusion, allow me to simplify the case and assist you in learning everything there is to know about this historic legal battle!

For any load test to be accurate, the battery must be fully charged and left to sit 12 hours before load testing the battery. Your local automotive shop is more than able to load test your battery, but it's quite easy to do at home and all you need is a digital voltmeter. The majority of replacement battery purchases occur when the original battery has reached this point. At this point, charging alone will not restore the battery to a healthy condition. Charging a sulfated battery is like trying to wash your hands while wearing gloves. Sulfation decreases the potential to reach a full charge, and it self-discharges the battery quicker than normal. This covers the surface area of the plates, removing the chemicals needed to produce power. But if a battery sat, uncharged, severely discharged, and/or drained for extended periods of time, the sulfation will increase in size and harden onto the plates. Naturally, re-charging the battery will reverse the sulfation crystals and turn it back into electrolyte, ready to produce power again. Sulfation is the natural byproduct when the battery discharges.

If running water is not available, use moistened towelettes to remove the visible soil, followed by alcohol-based hand rub. Handwashing with soap and running water must be done when hands are visibly soiled. It is better than washing hands (even with antibacterial soap) when hands are not visibly soiled. How to clean hands: Two methods Alcohol-based hand rub is the preferred method for cleaning hands. Adapted from the Swiss Hand Hygiene Campaign Hand hygiene with soap and water – done correctly – removes organisms. Why does hand hygiene work? Hand hygiene with alcohol-based hand rub – correctly applied – kills organisms in seconds.

Element synonym etynomolgy10/6/2023 Īll other isotopes of aluminium are radioactive. ![]() The standard atomic weight of aluminium is low in comparison with many other metals. This makes aluminium very useful in nuclear magnetic resonance (NMR), as its single stable isotope has a high NMR sensitivity. ![]() Nearly all aluminium on Earth is present as this isotope, which makes it a mononuclidic element and means that its standard atomic weight is virtually the same as that of the isotope. the only one that has existed on Earth in its current form since the formation of the planet. It is the only primordial aluminium isotope, i.e. This situation is common for elements with an odd atomic number. Because of the abundance of these salts, the potential for a biological role for them is of interest, and studies continue. In the 21st century, most aluminium was consumed in transportation, engineering, construction, and packaging in the United States, Western Europe, and Japan.ĭespite its prevalence in the environment, no living organism is known to use aluminium salts for metabolism, but aluminium is well tolerated by plants and animals. In 1954, aluminium became the most produced non-ferrous metal, surpassing copper. In World Wars I and II, aluminium was a crucial strategic resource for aviation. Aluminium became much more available to the public with the Hall–Héroult process developed independently by French engineer Paul Héroult and American engineer Charles Martin Hall in 1886, and the mass production of aluminium led to its extensive use in industry and everyday life. The first industrial production of aluminium was initiated by French chemist Henri Étienne Sainte-Claire Deville in 1856. The discovery of aluminium was announced in 1825 by Danish physicist Hans Christian Ørsted. It is obtained industrially by mining bauxite, a sedimentary rock rich in aluminium minerals. The strong affinity towards oxygen leads to aluminium's common association with oxygen in nature in the form of oxides for this reason, aluminium is found on Earth primarily in rocks in the crust, where it is the third-most abundant element, after oxygen and silicon, rather than in the mantle, and virtually never as the free metal. The aluminium cation Al 3+ is small and highly charged as such, it is polarizing, and bonds aluminium forms tend towards covalency. The radioactivity of 26Al is used in radiometric dating.Ĭhemically, aluminium is a post-transition metal in the boron group as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. ![]() It has one stable isotope: 27Al, which is highly abundant, making aluminium the twelfth-most common element in the universe. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It has a great affinity towards oxygen, forming a protective layer of oxide on the surface when exposed to air. Aluminium has a density lower than those of other common metals about one-third that of steel. Aluminium ( aluminum in North American English) is a chemical element with the symbol Al and atomic number 13. AuthorWrite something about yourself. No need to be fancy, just an overview.
