nokia 9 pureview

Unlike other multi-camera phones, like the LG V40 or Samsung’s newly announced Galaxy S10, the Nokia 9 PureView uses the same key specs for all five cameras: each one has a 12 megapixel sensor and an f/1.8 lens. But only two of those five cameras shoot in color — the other three are monochrome.   Whenever you press the shutter, all five cameras shoot different exposures at the same time, which then get merged together into a single, ultra-detailed shot. Depending on the scene composition, Nokia says that individual cameras can even shoot multiple exposures on their own to add even more data to the final image. The result — at least in theory — is a smartphone camera that offers new levels of detail and color. As one might have expected from seeing a device with this many cameras, Nokia partnered with Light ( makers of the 16-camera L16 ), making it the first phone that the camera company has contributed to. Nokia is actually employing Light’s Lux Capacito...

facebook dilemma

trailer part one https://www.youtube.com/watch?v=T48KFiHwexM part two https://www.youtube.com/watch?v=EuA4qxPbpQE PBS Frontline's interactive version Throughout the documentary, which is swiftly paced but cogently focused on a few themes, we hear of warning signs about the political abuses of Facebook going unheeded. The company didn’t want to deal with safety and security until it absolutely had to. Understaffing (galling, considering the profits involved), a lack of governmental regulation and other factors combined with a moment in American culture when “hyperpartisan” divisions became a ripe new business model. As Roger McNamee, an early Facebook investor, says to Jacoby: “Fear and anger” creates “greater engagement,” and therefore “more advertising value.” With the midterm elections coming soon, Facebook has created an “election integrity team” to help Zuckerberg’s creation to learn from its past mistakes. “The Facebook Dilemma” chronicles those mis...

confusing espresso brew ratio: 1:1 shot, 1:2 shot and a 1:3 shot

first of all the brew ratio is not same brewing ratio in SCAA from SCAA : The ratio of coffee grounds (mass) to water (volume): how much coffee is used for a given quantity of water. This may be expressed in units of either grams per litre this is mainly used for unpressurised brewing, eg drip, pourover or french press brewing. This can be simply called as coffee-to-water ratio it is recommended to be 55 g /L +/- 10%.     The brew ratio ( or simply ratio of coffee grounds (mass) to water (volume)): how much coffee is used for a given quantity of water. This may be expressed in units of either grams per litre or ounces per US half gallon. These are related as follows:     Strength = Brew ratio × Extraction which can be analyzed as the following identity:     dissolved solids/water = grounds/water × dissolved solids/grounds So Brew ratio = Strength / Extraction or          ...

EPAWSS Eagle passive / Active Warning and Survivability System

With Boeing, the F-15 manufacturer, as prime contractor and integrator, the Epawss system is expected to include a new digital internal radar warning receiver, upgraded chaff-and-flare dispenser and a new fiber-optic towed decoy. The new system will also address "capability gaps as threats evolve," ACC officials say. "The threat environment is becoming congested and contested [and] F-15s need a modern EW system to remain viable in the future operational environment." The emergence of Digital Radio Frequency Memory technologies also has frustrated allied EW technology, driving a need for upgrades. Using DRFM, an adversary can swiftly replicate signals, allowing for fast and accurate jamming in the air battle. Though ACC officials say TEWS "lacks performance to counter current/future threats," Epawss introduction into service is beyond the future years defense plan, or beyond 2020. Installs for developmental testing aircraft are slate...

water recipe for coffee

from james Hoffman's book "how to make the best coffee at home", actually adapted from  Jon Gagne "physics of filter coffee" grindscience : above: NaHS04 should be NaHCO3. Alkanity should be 27.6ppm /mk alkalinity  , or 595.6 ppm for each g of Sodium Bicarbonate added to 1L of water. Anyways, this looks rather like a concentrate, ( 1000 times too strong) barista hustle diy water recipes, the world in two bottles Recipe 4 – Barista Hustle Water Recipe 48.8g Buffer 19.4g Mg 931.8g DI water The original Barista Hustle water recipe — where it all began.

science of coffee extraction

In a drip filter machine the brewing process consists of three stages. Initially in the filling stage, hot water is poured on the dry coffee grounds and begins to fill the filter, but doesn’t leave. In the steady state stage the bed is saturated, water is still entering the filter, but also leaving at the same rate. Finally in the draining stage no more water enters the bed but still drains out. Only the steady state stage is considered in this study. grind size: "The really surprising thing to us is that there are really two processes by which coffee is extracted from grains. “Initially, the concentration of coffee in the bed is determined by the balance between a rapid extraction from the surfaces of coffee grains and the rate at which coffee is removed from the coffee bed by the extracting water. Later in the process, the extraction is dominated by slow diffusion of coffee from the kernels of larger grains, which was initially negligible.” It had previous...

semi-carbonic fermentation

The microlot was processed with a anaerobic fermentation technique that enhanced the acidity, making it sparkling with notes of orange, peach and pineapple, with honey-like sweetness. Emi Fukahori (Switzerland) - WBrC Champion 2018 Laurina, or “Bourbon Pointu” is a rare varietal from the Reunion Islands of small, pointy beans that usually present a lower caffeine amount than other Arabica varietals. Harvesting: hand picked Process: semi-carbonic fermentation Drying: raised beds, finished on stainless steel drum drier tasting notes: orange, honey, peach, pineapple, sparkling WBrC 2018   Adding fruit to fermentation: Recent experiments have led some producers to include fruit when fermenting coffee. One such example is where cherries are fermented in a sealed, airtight tank for anaerobic fermentation along with a pre-established percentage of whole fruits or extracts (often sugar cane juice or citrus fruits). This mixture is then fermented in the t...

carbonic maceration

Carbonic Maceration is the process of fermenting grapes in an anaerobic environment rather than an aerobic one, meaning the fermentation process actually happens inside the grape, without oxygen.  In an aerobic situation, the grapes are crushed, allowing oxygen to interact with the yeasts, which then convert sugar to alcohol and CO2.  That’s the basic fermentation. In an anaerobic situation, grapes are put in a tank and oxygen is replaced with carbon dioxide . This prompts a chemical reaction inside the grape, where sugars are converted into alcohol while the grape remains whole.   What’s the difference? First, the wine spends virtually no time on its skins, so it does not absorb the tannins, color or other phenolics that skins provide during fermentation . The result are wines that are fruity in aroma and flavors, sometimes with a distinct banana aroma. They lack tannins, and deep color. Carbonic Maceration is most commonly practiced in ...

Eco and Eco trend in life

WHAT IS ECO? Today, the world is facing heavy pollution due to the destruction of ecosystems over a long period of time due to waste discharge and unplanned exploitation. Eco has become a trend of enthusiastic support from the community thanks to the many benefits it brings: limiting waste which adversely affects the environment, balancing the ecosystem, preventing many natural disasters and harassment. yards ... So what is Eco? Eco is an abbreviated state of the word ecology. Ecology means ecology is the science that studies the distribution and life of living organisms and the interactions between organisms and their habitats. So, all activities in the fields of curving life in particular are operated according to the above rules ie expressing eco style. Eco style (translated as ecological trend) appeared in the early years of the 20th century, calling for a lifestyle that shows a high sense of responsibility to the environment, limiting bad impacts on the environment to protect the ...

Industry seeks options for plastic straw

The global campaign against the use of plastic straws has been gaining adherence by companies and public authorities thanks to a growing wave that has relied on the help of social networks and millions of consumers who condemn the use of the product because of waste discarded in the environment, especially in the oceans. Some American cities have already turned the war to disposable plastic into law. This is the case in Seattle, which in July passed a ban on using utensils made from petroleum-based resin in restaurants, cafes, and food stores. Those who fail to comply with the rule will pay fines starting at $ 250. In the United States alone, the daily consumption of drinking straw reaches 500 million units per day. In nature, its decomposition time is approximately 200 years. In Brazil, the city of Rio de Janeiro was the first to adopt this type of restriction. Since last month, bars, restaurants and kiosks are required to offer paper straws. The punishment for those who do not follow...
