A good example of organizations fighting for their survival whether they have reason to exist or not:
Legalizing marijuana “insults our common values” and insisted that “every single parent out there” opposed legalization. What do you think, that people who are in favor of decriminalization or changing policy don’t procreate?
such nice technology being wasted on selfies and baby pictures.
Facebook, one of the primary backers of the Internet.org initiative, which aims to bring affordable Internet access to the 5B people in the world who still lack connectivity, is in talks with a company that could help further that agenda. Facebook is buying Titan Aerospace, makers of near-orbital, solar-powered drones which can fly for 5 years without needing to land.
FirstNet—pitched as a state of the art communications network for paramedics, firemen and law enforcement at the federal, state and local level—will give cops on the streets unprecedented technological powers, and possibly hand over even more intimate data about our lives to the higher ends of the government and its intelligence agencies. The system has already been tested in a handful of states, and 2014 will likely see it rolled out further.
apparently it’s going to be called DonutNet
A Dark Pattern is a type of user interface that appears to have been carefully crafted to trick users into doing things, such as buying insurance with their purchase or signing up for recurring bills.
I assume that if a student shoots first, I am allowed to empty my clip; but given the velocity of firearms, and my aging reflexes, I’d like to be proactive. For example, if I am working out a long equation on the board and several students try to correct me using their laser sights, am I allowed to fire a warning shot?
“During the time in 2011 when political warfare over the debt ceiling was beginning to paralyze the business of governance in Washington, the United States government somehow summoned the resources to overthrow Muammar Ghaddafi’s regime in Libya, and, when the instability created by that coup spilled over into Mali, provide overt and covert assistance to French intervention there. At a time when there was heated debate about continuing meat inspections and civilian air traffic control because of the budget crisis, our government was somehow able to commit $115m to keeping a civil war going in Syria and to pay at least £100m to the United Kingdom’s Government Communications Headquarters to buy influence over and access to that country’s intelligence. Since 2007, 2 bridges carrying interstate highways have collapsed due to inadequate maintenance of infrastructure, 1 killing 13 people. During that same period of time, the government spent $1.7m constructing a building in Utah that is the size of 17 football fields.
Americans for a Gay Arizona has already received commitments from 1M gay Americans to move to the state within the next 2 months, with a target of enlisting over 6M gays to move there by the end of the year.
A fitting memento on the day when Tesla announces plans to bring 50 GWh / year of li-ion battery online (current world production is 27 GWh): The Tesla induction motor has been called one of the 10 greatest inventions of all time.
2015-03-10: Check out this site visit at the first Gigafactory. When complete, it will be the largest footprint manufacturing building in the world. The scale can be deceiving; this 2-story structure is 24m tall.
2016-10-28: The powerwall is extremely impressive. The difference between wantrepreneurs like “secret” and actual ones is off the scale
Musk didn’t waste anybody’s time. He used that time to present a problem of critical importance (eliminating humanity’s use of fossil fuels), explained how it can be addressed, and offered a plausible solution in the form of a new product — one that’s priced within reach of a lot of people and available to order. Amazingly, all of those things are actually pretty rare to see in one show. Tesla’s presentation was inspiring, and Musk wasn’t selling some fancy scifi trinket that has the benefit of Star Trek nostalgia. Dude was selling a battery.
2019-06-07: Tesla has a big lead for dry batteries
Tesla cars have been able to last for 1.6M km but starting in 2020 the battery packs will be able to last for 1.6M km. Currently, the battery packs last for 500-800K km. Most non-electric cars only can last 160-320K km. Tesla will start using battery domination in 2020 with significantly longer lasting and higher energy density batteries. This will enable Tesla to use a mix of better prices and higher performance to win electric cars, electric trucks and with electric taxis.
2019-10-15: They’re investing in their battery manufacturing
Tesla bought Hibar Systems, a world leader in the development of battery manufacturing technology. Hibar is truly unique in its capability to provide the world’s leading manufacturers with innovative advanced automation solutions that are engineered specifically to suit their production automation requirements ranging from simple single station bottle filling systems to sophisticated high-speed assembly systems running in excess of 1000 parts per minute. This unique capability is made possible through Hibar’s vertically integrated structure.
2019-11-30: Over time, their batteries can get 3x cheaper
Lithium Ion batteries can get 3x cheaper than current average prices of $180 per kwh to $50-60 per kwh.
2020-10-02: By doing all this, they’re speeding up the industry by decades.
If Tesla achieves the goals of Battery Day then they bring forward the electrification of transportation and energy by decades. BloombergNEF projected lithium-ion batteries to halve their cost by 2030. Tesla plans to halve the cost by 2023. Half of what Tesla would do in 2030 and 2031 would surpass the cumulative projection of energy storage installations by 2040.
2020-10-21: They’ve, as of late 2020, achieved 5m km lifespans. This is enough charge cycles to last 25 years, longer than the cars, so the batteries can be reused for other applications, and can do other functions like grid storage.
If batteries become 2x cheaper over 7 years and 120 Gigabattery factories are made then combustion engine cars are replaced and Tesla is worth 50x more than today.
you’ll want to go easy on that sushi and switch to sea weed. 20% of fish stocks have collapsed, and 60% are overexploited. there are no reserves left.
newton’s masterpiece philosophiæ naturalis principia mathematica which is available online in a translated edition with the original pictures. the principia is justly regarded as one of the most important works in the history of science.
