Jack Dorsey is een Amerikaanse zakenman die vooral bekend staat als de oprichter van de sociale netwerksite Twitter.

Korte inhoud

Jack Dorsey, geboren op 19 november 1976 in St. Louis, Missouri, raakte als student betrokken bij webontwikkeling en richtte in 2006 de sociale netwerksite Twitter op. Sinds die tijd is Dorsey CEO, voorzitter van de raad van bestuur, en uitvoerend voorzitter van Twitter. Hij lanceerde ook het succesvolle online betalingsplatform Square in 2010.

Vroege leven

Uitvinder van Twitter Jack Dorsey werd geboren op 19 november 1976 in St. Louis, Missouri. Opgroeiend in St. Louis raakte Dorsey op jonge leeftijd geïnteresseerd in computers en communicatie en begon hij te programmeren terwijl hij nog studeerde aan bisschop DuBourg High School . Hij was gefascineerd door de technologische uitdaging van het coördineren van taxichauffeurs, bestelauto's en andere wagenparken die constant in realtime met elkaar moesten communiceren. Toen hij 15 was, schreef Dorsey verzendsoftware die nog steeds door sommige taxibedrijven wordt gebruikt.

Creatie van Twitter

Na een korte periode bij de Missouri University of Science and Technology, ging Dorsey over naar de New York University. In de traditie van informatica-ondernemers zoals Bill Gates, Steve Jobs en Mark Zuckerberg stopte hij met studeren voordat hij zijn diploma behaalde. In plaats daarvan verhuisde Dorsey naar Oakland, Californië, en startte in 2000 een bedrijf dat zijn dispatch-software via het web aanbood. Kort na het opstarten van zijn bedrijf kwam Dorsey op het idee voor een site die het brede bereik van verzendsoftware zou combineren met het gemak van instant messaging.

Dorsey benaderde een inmiddels ter ziele gegane Silicon Valley-bedrijf genaamd Odeo om het concept te pitchen. "Hij kwam naar ons met dit idee: 'Wat als u uw status heel gemakkelijk met al uw vrienden zou kunnen delen, zodat zij weten wat u bent'opnieuw bezig?'"zei Biz Stone, een voormalige Odeo-directeur. Dorsey, Stone en Odeo mede-oprichter Evan Williams startte een nieuw bedrijf, genaamd Obvious, dat later evolueerde naar Twitter. Binnen twee weken had Dorsey een eenvoudige site gebouwd waar gebruikers direct konden posten berichten van 140 tekens of minder, in Twitter-taal bekend als 'tweets'.

Op 21 maart 2006 heeft Jack Dorsey de wereld gepost's eerste tweet: "gewoon mijn twttr instellen." Dorsey werd het bedrijf genoemd's chief executive officer. Hij verwijderde zijn neusring in een poging om naar het deel van een volwassen bestuurder uit Silicon Valley te kijken, hoewel hij zijn jongensachtige, dweilachtige kapsel en abstracte, onderarmlengte tatoeage hield waarvan de vorm onder andere het menselijke sleutelbeen vertegenwoordigde. Mede-oprichter Evan Williams verving Dorsey als Twitter's CEO in oktober 2008, met Dorsey als bedrijfsvoorzitter.

Twitter-succes

Twitter werd aanvankelijk door sommigen bespot als een hulpmiddel voor de oppervlakkige en egocentrische om de details van hun leven naar het universum uit te zenden. Komedie met late comedy Conan O'Brien had zelfs een segment genaamd "Twitter Tracker" dat gebruikers van de dienst bespotte. In de begindagen had de site ook te maken met frequente servicestoringen. Maar toen beroemdheden en CEO's begonnen te tweeten, was Twitter niet langer de dupe van zoveel grappen. Plotseling het hoofd van de "microblogging" -beweging, werd Twitter een krachtig platform voor Amerikaanse presidentskandidaten Barack Obama en John McCain in 2008, als een methode voor het bijwerken van hun supporters tijdens het campagnetraject.

Twitter sprong over naar internationale bekendheid na de presidentsverkiezingen van juni 2009 in Iran, toen duizenden oppositieleden de straat op gingen om te protesteren tegen de geclaimde overwinning van de gevestigde Mahmoud Ahmadinejad. Toen de overheid sms-berichten en satellietfeeds van berichtgeving in het buitenland blokkeerde, overspoelden Iraanse Twitter-gebruikers de site met live updates. Een functionaris van het Amerikaanse ministerie van Buitenlandse Zaken stuurde Dorsey zelfs een e-mail om Twitter te vragen het geplande onderhoud uit te stellen zodat demonstranten konden blijven tweeten. "Het lijkt erop dat Twitter een belangrijke rol speelt op een cruciaal moment in Iran. Kun je het volhouden?" zei een woordvoerder van het ministerie van Buitenlandse Zaken die de oproep beschreef. Twitter heeft voldaan.

Voorbij Twitter

In 2010 had Twitter meer dan 105 miljoen gebruikers die samen zo'n 55 miljoen keer per dag tweeten. Dorsey had zijn zinnen echter op andere projecten gericht. Hij werd een investeerder in het sociale netwerkbedrijf Foursquare en lanceerde een nieuwe onderneming, Square, waarmee mensen creditcardbetalingen kunnen ontvangen via een klein apparaat dat op hun mobiele telefoon of computer is aangesloten. Twitter heeft misschien al een revolutie teweeggebracht in de manier waarop mensen communiceren, maar Dorsey is dat niet'nog niet klaar. "In termen van technologie, wij'we gaan een betere en meer directe ervaring zien rond de dagelijkse dingen die we in het leven doen, "zei Dorsey.

Miljardair zakenman

In november 2013 zag Dorsey zijn persoonlijk fortuin enorm groeien dankzij Twitter'eerste openbare aanbieding. Het bedrijf's aandeel had een startkoers van $ 26, maar de prijs steeg snel tot $ 45 tijdens de eerste handelsdag. Binnen enkele uren is de waarde van Dorsey's ongeveer 23,4 miljoen aandelen maakten hem miljardair. Hij begon al in 2014 de mogelijkheid van een IPO voor zijn andere bedrijf, Square, te bespreken.

In 2015 keerde Dorsey terug naar Twitter. Hij diende eerst als interim CEO en werd vervolgens CEO. Niet lang daarna nam hij officieel het bedrijf over'Op de eerste plaats kondigde hij aan dat het bedrijf ongeveer 8% van zijn personeelsbestand zou verminderen. Deze stap maakt deel uit van een algemeen plan om zich binnen het bedrijf te organiseren's topproductprioriteiten en efficiëntie in het hele bedrijf, & # x201D; volgens een effectendossier door Twitter gemeld in de Los Angeles Times.

Broken spheres Dyson died in 2020 before any of his spheres could be found — although they are just one of a dozen ideas that bear his name. <a href=https://kra30att.cc>kra31 at</a> “As a young scientist, Dyson showed that three competing quantum theories were actually the same theory — he summarily ended the competition,” said William Press, the Leslie Surginer Professor of Computer Science and Integrative Biology at the University of Texas at Austin. He was not involved in the study. “Later, he applied his genius to areas of astronomy, cosmology, the extraterrestrial realm, and also the very real problem of nuclear proliferation here on planet Earth. At the time of his death, he was recognized as a provocative and creative thinker.” George Dyson also attested to his father’s fascination and comprehensive reach across disciplines. https://kra30att.cc kra at “Taking advantage of a short attention span and an aversion to bureaucracy, he contributed to five fields of mathematics and eleven fields of physics, as well as to theoretical biology, engineering, operations research, literature, and public affairs,” the younger Dyson said. “Many of his ideas were controversial, with one of his guiding principles being that ‘It is better to be wrong than to be vague.’” The approach of the researchers behind the new study could offer a more fruitful path in the search for extraterrestrial intelligence, said Tomotsugu Goto, an associate professor of astronomy at the National Tsing Hua University in Taiwan. He also was not involved with the study. “However, contamination by circumstellar debris disks, which mimic Dyson Sphere infrared signatures, remains a concern,” he added in an email. “Authors argue that the debris disks around (dwarf stars) are rare, but the 7 candidate authors selected out of 5 million sources are also rare. Despite this, the seven candidates warrant further investigation with powerful telescopes for a more definitive evaluation.”

Why axolotls seem to be everywhere — except in the one lake they call home <a href=https://kra30s.cc>kraken darknet</a> Scientist Dr. Randal Voss gets the occasional reminder that he’s working with a kind of superstar. When he does outreach events with his laboratory, he encounters people who are keen to meet his research subjects: aquatic salamanders called axolotls. The amphibians’ fans tell Voss that they know the animals from the internet, or from caricatures or stuffed animals, exclaiming, “‘They’re so adorable, we love them,’” said Voss, a professor of neuroscience at the University of Kentucky College of Medicine. “People are drawn to them.” https://kra30s.cc kraken войти Take one look at an axolotl, and it’s easy to see why it’s so popular. With their wide eyes, upturned mouths and pastel pink coloring, axolotls look cheerful and vaguely Muppet-like. They’ve skyrocketed in pop culture fame, in part thanks to the addition of axolotls to the video game Minecraft in 2021. These unusual salamanders are now found everywhere from Girl Scout patches to hot water bottles. But there’s more to axolotls than meets the eye: Their story is one of scientific discovery, exploitation of the natural world, and the work to rebuild humans’ connection with nature. A scientific mystery Axolotl is a word from Nahuatl, the Indigenous Mexican language spoken by the Aztecs and an estimated 1.5 million people today. The animals are named for the Aztec god Xolotl, who was said to transform into a salamander. The original Nahuatl pronunciation is “AH-show-LOAT”; in English, “ACK-suh-LAHT-uhl” is commonly used. Axolotls are members of a class of animals called amphibians, which also includes frogs. Amphibians lay their jelly-like eggs in water, and the eggs hatch into water-dwelling larval states. (In frogs, these larvae are called tadpoles.) Most amphibians, once they reach adulthood, are able to move to land. Since they breathe, in part, by absorbing oxygen through their moist skin, they tend to stay near water. Axolotls, however, never complete the metamorphosis to a land-dwelling adult form and spend their whole lives in the water. “They maintain their juvenile look throughout the course of their life,” Voss said. “They’re teenagers, at least in appearance, until they die.”

Axolotl problems As Mexico City grew and became more industrialized, the need for water brought pumps and pipes to the lake, and eventually, “it was like a bad, smelly pond with rotten water,” Zambrano said. “All of our aquatic animals suffer with bad water quality, but amphibians suffer more because they have to breathe with the skin.” <a href=https://lucky-jetts.com>lucky jet игра</a> To add to the axolotls’ problems, invasive fish species such as carp and tilapia were introduced to the lake, where they feed on axolotl eggs. And a 1985 earthquake in Mexico City displaced thousands of people, who found new homes in the area around the lake, further contributing to the destruction of the axolotls’ habitat. These combined threats have devastated axolotl populations. According to the International Union for Conservation of Nature, there are fewer than 100 adult axolotls left in the wild. The species is considered critically endangered. https://lucky-jetts.com лаки джет играть While the wild axolotls of Lake Xochimilco have dwindled to near-extinction, countless axolotls have been bred for scientific laboratories and the pet trade. “The axolotl essentially helped establish the field of experimental zoology,” Voss said. In 1864, a French army officer brought live axolotls back to Europe, where scientists were surprised to learn that the seemingly juvenile aquatic salamanders were capable of reproduction. Since then, scientists around the world have studied axolotls and their DNA to learn about the salamanders’ unusual metamorphosis (or lack thereof) as well as their ability to regrow injured body parts. In addition to their role in labs, axolotls have become popular in the exotic pet trade (though they are illegal to own in California, Maine, New Jersey and Washington, DC). However, the axolotls you might find at a pet shop are different from their wild relatives in Lake Xochimilco. Most wild axolotls are a dark grayish brown. The famous pink axolotls, as well as other color variants such as white, blue, yellow and black, are genetic anomalies that are rare in the wild but selectively bred for in the pet trade. What’s more, “most of the animals in the pet trade have a very small genetic variance,” Zambrano said. Pet axolotls tend to be inbred and lack the wide flow of different genes that makes up a healthy population in the wild. That means that the axolotl extinction crisis can’t simply be solved by dumping pet axolotls into Lake Xochimilco. (Plus, the pet axolotls likely wouldn’t fare well with the poor habitat conditions in the lake.)

‘Dyson spheres’ were theorized as a way to detect alien life. Scientists say they’ve found potential evidence <a href=https://kra30c.cc>kraken onion</a> What would be the ultimate solution to the energy problems of an advanced civilization? Renowned British American physicist Freeman Dyson theorized it would be a shell made up of mirrors or solar panels that completely surrounds a star — harnessing all the energy it produces. “One should expect that, within a few thousand years of its entering the stage of industrial development, any intelligent species should be found occupying an artificial biosphere which completely surrounds its parent star,” wrote Dyson in a 1960 paper in which he first explained the concept https://kra30c.cc kraken darknet If it sounds like science fiction, that’s because it is: Dyson took the idea from Olaf Stapledon’s 1937 novel “Star Maker,” and he was always open about that. The late scientist was a professor emeritus at the Institute of Advanced Study in Princeton, New Jersey. Still, coming from a thinker who some in the scientific community say might have been worthy of a Nobel Prize early in his career, the concept took hold and the hypothetical megastructures became known as Dyson spheres, even though the physicist later clarified that they would actually consist of “a loose collection or swarm of objects traveling on independent orbits around the star.” In his paper, Dyson also noted that Dyson spheres would give off waste heat detectable as infrared radiation, and suggested that looking for that byproduct would be a viable method for searching for extraterrestrial life. However, he added that infrared radiation by itself would not necessarily mean extraterrestrial intelligence, and that one of the strongest reasons for searching for such sources was that new types of natural astronomical objects might be discovered. “Scientists (at the time) were largely receptive, not to the likelihood that alien civilisations would be found to exist, but that a search for waste heat would be a good place to look,” said George Dyson, a technology writer and author and the second of Dyson’s six children, via email. “Science fiction, from ‘Footfall’ to ‘Star Trek,’ took the idea and ran with it, while social critics adopted the Dyson sphere as a vehicle for questioning the wisdom of unlimited technological growth.”
